BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of a garbage recycling system according to the present invention will be described with reference to examples shown in the drawings. First, FIG. 1 shows an outline of a garbage recycling system according to the present invention.
[0014]
Garbage collected from restaurants and grocery stores is mixed with relatively light foreign substances such as packaging materials (vinyl chloride resin containers, wrapping materials for packaging, etc.). It may take a long time for the chemical conversion step 603 or the like, or the environment may be polluted by scattering of foreign contaminants. In addition, the water content of these garbage reaches about 80%, and in the garbage carbonization step 604 and the like, far exceeds the optimum value of about 60%, which is the optimum value for the propagation of microorganisms, so that fermentation and decomposition by microorganisms are suppressed. Therefore, there is a possibility that a long time is required for the carbonization step 604 or the like, or the vitality of the microorganism-supporting material (microorganism bed) containing the microorganisms is hindered.
[0015]
Therefore, in the garbage recycling system according to the present invention, first, the garbage is separated from the garbage or the like mixture in which the garbage or the like is mixed with the garbage. A heterogeneous contaminant separation step 601 for subdividing into predetermined particles or fragments is performed, and then a water content adjustment step 602 for reducing the water content of garbage from the initial 80% to about 50% is performed. In addition, this water content adjustment step 602 reduces the water content of garbage by one or more combinations of water content adjustment materials such as sawdust, pruning chips, rice husks, hay and the like, heating evaporation and dry air ventilation. Adjust below a certain rate.
[0016]
Next, a composting step 603 in which the raw garbage that has passed through the foreign matter separation step 601 and the water content adjustment step 602 is fermented and aged through microorganisms to be regenerated into compost, and the raw garbage is heated to a predetermined temperature or higher. A carbonization step 604 for regenerating carbon by charcoalization, a garbage elimination step 605 for eliminating garbage by fermenting and decomposing garbage into microbial feed, and a fermentation feed by fermenting garbage through microorganisms. Any of the steps of the feed converting step 606 to be regenerated is executed alternatively.
[0017]
Of these, garbage is mixed with a microorganism-carrying material (bacterial bed) containing microorganisms, and the mixture is fermented and decomposed under predetermined conditions to obtain a garbage elimination step 605 in which garbage is almost eliminated. When the garbage elimination step 605 is executed, the garbage cannot be used as compost and a circulation system of the garbage recycling system cannot be formed. However, it can be said that this is one effective processing method from the viewpoint of environmental pollution prevention.
[0018]
Furthermore, fermented feed is used as livestock feed in animal husbandry, compost is used for fertilization on farms, and charcoal is used for deodorization and soil improvement at farms, etc., and the consumption of farm products or livestock products harvested at farms etc. In some cases, the residue discarded due to (sales or provision of food) is recycled as garbage again.
[0019]
Next, in the garbage recycling system shown in FIG. 1, an example of a separation apparatus that can be used in the foreign matter separation step 601 is shown in FIGS.
[0020]
FIG. 2 is a front sectional view of an apparatus for separating foreign contaminants of a mixture such as garbage (hereinafter, simply referred to as a separation apparatus), and FIG. The separation device 1 has a separation body 10 that separates a mixture M such as garbage supplied from the rotary supply device 40 into garbage G and foreign substances X (see FIG. 4). Is designed to be able to be taken out from the garbage outlet 61 and the foreign matter X is to be taken out from the foreign matter take-out passage 62, and the garbage G is used as a raw material for composting, feed conversion and the like.
[0021]
The separating body 10 of the separating device 1 has an inner peripheral surface formed in a horizontally-inverted cylindrical shape extending substantially in a horizontal direction, and a sorting hole 12 is formed in a lower portion of the cylindrical inner peripheral surface. Are formed by a punching metal (porous member) in which a large number is formed. The sorting body 10 accommodates the mixture M such as garbage at a filling rate equal to or less than a predetermined value, and the separation hole 12 allows the garbage G having a size equal to or less than a predetermined value to pass therethrough while allowing foreign matter X (wrapping material such as wrap) to pass through. It is set to a size that does not allow passage (for example, a hole diameter of 20 to 40 mm × a pitch of 10 to 50 mm). In the present embodiment, the separation hole 12 is formed only in the lower portion of the inner peripheral surface of the separation body 10, but may be formed over the entire circumference.
[0022]
A rotating shaft 22 is arranged inside the sorting body 10 along the depth direction of the sorting body 10, and the rotating shaft 22 is provided with a crushing blade (hereinafter simply referred to as a blade) 25. The blade 25 is rotated by the driving device 30 including the motor 31 and the speed reducer 32 in the sorting body 10, and is a rotary crushing member that crushes the garbage G together with the rotation shaft 22 to a predetermined size or less. 24.
[0023]
Specifically, when viewed from the axial direction as shown in FIG. 4, the blade portion 25 is disposed substantially concentrically with the center line O (see FIG. 3) of the cylindrical inner peripheral surface of the sorting body 10. A plurality (four in the figure) is fixed to the rotating shaft 22 at a predetermined interval along the circumferential direction, and protrudes toward the cylindrical inner peripheral surface of the sorting body 10, and the tip is close to the inner peripheral surface. In addition, the blade portion 25 has a long plate shape that extends over substantially the entire length of the rotating shaft 22 in the axial direction.
[0024]
Returning to FIG. 2, in order to supply the mixture M such as garbage to the separation body 10, the separation device 1 is coaxially and integrally with the rotary shaft 22 so as to cooperate with the rotary shaft 22 of the rotary crushing member 24. A rotation supply device 40 is provided. The rotation supply device 40 is rotated in association with the rotation speed of the rotary crushing member 24 using the driving device 30 of the rotary crushing member 24 as a common driving source, so that a predetermined amount of the mixture M Supply.
[0025]
Specifically, as shown in FIG. 5, the rotation supply device 40 includes an extension shaft (screw shaft) provided coaxially with the rotation shaft 22 of the rotary crushing member 24 so as to be located on an extension of the rotation shaft 22. ) 41, a screw 43 having a spiral blade 42 formed on the outer periphery of the extension shaft 41, a housing 44 for storing the screw 43 therein, and a mixture M formed in the housing 44 to remove the garbage such as garbage. And an inlet (supply port) 45 to be inserted into the housing 44.
[0026]
Separation and removal of the foreign matter X from the mixture M such as garbage is performed as follows. When the rotary crushing member 24 and the screw 43 rotate in synchronization with each other by the driving device 30, a certain amount of the mixture M such as garbage is supplied to the separation body 10. The rotary crushing member 24 rotates and crushes the garbage G into particles or fragments having a certain size or less in the separation body 10, and only the crushed garbage G is separated from the large number of separation holes 12 by the separation body. It is discharged out of 10. On the other hand, since the foreign substance X is in the form of a sheet, it does not become small enough to pass through the separation hole 12 without being crushed or even if it is slightly crushed, and remains in the separation body 10. Thereby, the foreign substance X is separated from the mixture M such as garbage.
[0027]
At this time, it is assumed that the rotation shaft 22 of the rotary crushing member 24 and the screw shaft (extended shaft) 41 of the rotation supply device 40 rotate synchronously, and the transfer amount per rotation of the rotation shaft 22 and the screw shaft 41 is assumed. Is adjusted so that the discharge amount of the garbage G and the foreign matter X is substantially equal to the supply amount of the garbage mixture M, so that an appropriate amount of the garbage is An equal mixture M can be supplied. In order to make the discharge amount of the garbage G and the foreign matter X substantially equal to the supply amount of the garbage mixture M, the rotation shaft 22 and the screw shaft 41 are driven via rotation transmission means such as gears. By transmitting force, synchronous rotation may be performed. In this case, if a transmission device or the like (supply amount adjusting device) that changes the gear ratio is provided, a relative relationship between the processing amount per unit time in the separation body 10 and the supply amount to the separation body 10 is generated. It can also be changed according to the type of trash.
[0028]
The separation apparatus 1 includes a garbage collection unit 50 that collects garbage G discharged from the separation hole 12 to the outside of the separation body 10, and foreign matter left in the separation body 10 without passing through the separation hole 12. An air collection means 70 is provided to supply or generate a wind (also referred to as a pressure wind) for collecting the object X to the separation body 10.
[0029]
The garbage collection means 50 is disposed substantially parallel to the rotating shaft 22 of the rotary crushing member 24, is driven by a collection driving device 80 including a motor 81, a reduction gear 82, and the like, and has a screw provided with a spiral blade 52.

In this example, a plurality of bow-shaped (arc-shaped) wind direction guide plates 72 are fixed along the upper part of the cylindrical inner peripheral surface of the sorting body 10. In addition, the wind direction guide part 72 may be formed intermittently or continuously along a helix centering on the axis of the sorting body part 10. In any case, the flow of air generated by the rotation of the blades 25 is applied to the wind direction guide portion 72 in the separation body 10 to generate an air flow (wind) from one end of the separation body 10 to the other end. The foreign matter X left in the sorting body 10 is blown off (carrying on the wind) without passing through the sorting hole 12 due to the wind. That is, since the foreign matter X is usually lighter (has a lower specific gravity) than the garbage G, the wind generated by the rotation of the blade portion 25 enables the wind selection of the garbage G and the foreign matter X. In this way, the foreign matter X remaining in the sorting body 10 is discharged to the foreign matter discharge passage 62.
[0031]
In the above-described wind generation due to the interaction between the rotation of the blade portion 25 and the wind direction guide portion (guide plate) 72, wind is generated from one end side of the separation body 10 to the other end side. At the same time, air is guided into the separation body 10 from the separation hole 12 of the punching metal and the entrance 45 of the mixture such as garbage in the separation body 10, so that a steady flow of wind is continued.
[0032]
Further, as shown in FIG. 4, the foreign matter X discharged into the foreign matter discharge passage 62 is guided to a cyclone collecting device 63 (centrifugal separation and recovery means). Then, the foreign contaminant X that flows down while rotating along the inner wall and the conical portion of the outer cylinder of the cyclone collecting device 63 is discharged out of the apparatus from the lower foreign contaminant outlet 64 and stored in the pallet 65 or the like. . On the other hand, air is discharged from the air outlet 66 of the cyclone collecting device 63.
[0033]
In this embodiment, the garbage is collected by the screw conveyor 51 and the like, and the foreign matter is collected by the blade 25 and the wind direction guide 72. Can be used.

For example, for garbage after crushing,
(1) Conveying and collecting means using a belt conveyor
(2) Collection means for moving along a gutter whose bottom is inclined
(3) Collection means received in containers such as pallets
Etc. can be adopted.
[0035]
On the other hand, for foreign contaminants,

[0036]
Further, in this embodiment, the axis of the sorting body is substantially horizontal, but it may be provided in the vertical direction or the like. Further, the drive source 80 of the conveyor device 50 such as a screw for transporting the garbage discharged from the sorting body 10 in FIG. 2 is omitted, and the drive source 31 of the rotary crushing member 24 and the screw 43 is used as a common drive source ( It is also possible to carry out the discharged garbage (via a predetermined power transmission device).

As described above, in the drying chamber 150, steam is circulated through the outer cylinder side heat source circulation section 191 and the inner cylinder side heat source circulation section 192, and drying by heating based on contact with the outer cylinder section 110 or the inner cylinder section 120 is performed. Drying by heating and drying air that passes through the screw shaft side heat source circulation section 194 and blows out from the screw shaft side heat source outlet 194b at the lower end thereof is performed simultaneously. Therefore, drying of the garbage G can be further promoted.
[0054]
The supply pipe 184 and the screw shaft side heat source inlet 194a are connected to each other by a rotary joint 194c so as to be relatively rotatable, whereby the supply of heated and dried air to the screw shaft side heat source circulation section 194 and the rotation of the screw 124 generate The dust G can be transported between the inside and outside of the screw shaft 123 without any trouble. The heated and dried air spouted from the screw shaft side heat source outlet 194b also heats garbage moving at the end (lower end) of the descending space 151, the lower communication part 152 or the starting end (lower end) of the ascending space 153. A drying action can be exerted, and the drying efficiency of garbage can be increased. In addition, since the heating and drying air is heated by a common heating source (heat steam generator 181) with the steam, the heat piping system can be simplified.
[0055]
Further, the heated and dried air flowing through the inside of the screw shaft 123 can also heat the garbage G moving upward in the ascending space 153 from the center side of the garbage G to promote the evaporation of moisture, thereby further improving the drying efficiency. And the drying time can be shortened. In addition, the evaporation of the water from the garbage G may be further promoted by providing radial ejection ports on the peripheral surface of the screw shaft 123 and blowing heated dry air therefrom.
[0056]
In the vicinity of the upper communication portion 154, a duct 170 for exhausting moisture evaporated from the garbage G is provided. In the upper communication portion 154, which is a turning position from the ascending space 153 to the descending space 151, the gap between the garbage G is widened and scattered, so that the water is easily evaporated. Will be lost.
[0057]
In FIG. 6, reference numeral 200 denotes a screw driving device, which includes an electric motor with a speed reducer for driving the screw shaft 123, a transmission member such as a chain, and the like. Further, 210 is a heat insulating material for covering the drying chamber 150 from the outside to insulate it, 211 is a support frame for supporting the drying chamber 150 from the outside, 212 is an inspection port cover provided on the upper surface of the top 39, and 213 is a cover for the outer cylinder 110. This is an inspection lid provided on the outer peripheral surface.
[0058]
Next, the structure of the lower end portion and the bottom portion 130 of the screw shaft 123 will be described with reference to an enlarged view shown in FIG. As shown in FIG. 9A, the bottom portion 130 has a tapered inclined inner wall 131 and an inclined outer wall 132 having substantially equal inclinations (for example, 30 to 60 °). The stirring rod 125 (stirring member) that rotates integrally with the screw shaft 123 has one end or a plurality of stirrers 125 (in the figure, three at a predetermined interval in the circumferential direction) whose tip is bent toward the rotation direction during drying in a cross section orthogonal to the axis. Book; see FIG. 9B). The garbage G is stirred and guided from the descending space 151 to the ascending space 153 through the lower communication portion 152 while being stirred by the inclined inner wall 131 and the stirring rod 125. Therefore, the garbage G is smoothly taken into the start end of the screw 124 along the inclined inner wall 131, and even if the garbage G has a relatively large particle size, the stirring rod 125 does not hinder the flow and clogging occurs. It becomes difficult.
[0059]
Further, the upper end of the stirring rod 125 is located above the starting end (lower end) of the screw 124. By setting such a positional relationship, the garbage G is smoothly taken in the lower communication part 152 by the stirring rod 125.
[0060]
Further, since the starting end (lower end) of the screw 124 is located below the upper end of the inclined inner wall 131, clogging of the garbage G at the starting end of the rising space 153 can be prevented.
[0061]
In FIG. 9B, reference numeral 126 denotes a reinforcing material that also serves to fix the stirring rod 125 to the screw shaft 123.
[0062]
FIG. 10 shows a modification of the stirring member. A stirring blade 125a (stirring member) that rotates integrally with the screw shaft 123 is provided near the inclined inner wall 131, and the garbage G descends through the lower communication portion 152 while the garbage G is stirred by the inclined inner wall 131 and the stirring blade 125a. It is guided from the space 151 to the rising space 153 side. Therefore, the garbage G is smoothly taken into the starting end of the screw 124 along the inclined inner wall 131 also by the stirring blade 125a.
[0063]
Returning to FIG. 9A again, the bottom portion 130 is provided with an opening / closing take-out portion 160 for taking out the dried garbage G '. The bottom cover 161 that covers the central opening 130a of the bottom portion 130 is locked by the air cylinder 162 (for closing the air, etc.) during operation (during drying). When taking out the dried garbage G ', the upper end surface of the bottom cover 161 is positioned lower than the lower end surface of the bottom portion 130 via the air cylinder 162 (air release or the like). Next, the support arm 164 is rotated about the support shaft 163 in the axial direction by a large amount (preferably 90 to 180 °) to open the central opening 130a. Receiving the dried garbage G ′ falling from the central opening 130a in a container box CB or the like, or transporting it by a belt conveyor, a screw conveyor, air transport, or the like, and moving to an appropriate next process such as a composting process. I do. In addition, when the garbage G 'after drying is taken out, if the screw 124 is rotated in a direction opposite to the direction at the time of drying, the garbage G' after drying may be easily taken out.

Next, in the garbage recycling system shown in FIG. 1, a known composting device can be used in the composting step 603.
[0074]
12 and 13 show an example of such a composting device. FIG. 12 is a front view of the garbage composting device, and FIG. 13 is a side view thereof. The composting device 700 is rotatably provided around a center line, and has a tubular horizontal rotary downflow type inclined rotary body 720 provided with the center line tiltable within a predetermined angle range with respect to the horizontal direction. have. Then, for example, a packaging material such as a vinyl chloride resin-based container and a wrapping material for packaging is separated and removed by a foreign matter separation device (see FIGS. 2 to 5), and a moisture content is dried by a drying device (see FIGS. 6 to 11). Garbage reduced to about 50% is fed into the body from the high end of the inclined rotating body 720 through the supply device 710, and the composted garbage is provided at the low end. It can be taken out from the outlet 725 provided.
[0075]
The supply device 710 includes a belt conveyor 713 and a kneading machine 711, and includes garbage conveyed by the belt conveyor 713, a moisture content adjusting material (sawdust, pruning debris, chaff, rice hay, etc.) and bacteria containing microorganisms. The support material (bacterial bed) is mixed by a kneader 711 (see FIG. 13) driven by a kneader driving device 712. The mixture is supplied from the higher end of the rotating drum 721 to the inside while the rotating drum 721 constituting the inclined rotating body 720 is rotated by the drum driving device 722. When a predetermined amount of garbage or the like is stored in the rotating drum 721, the supply of the garbage or the like is stopped, and the fermentation process in the rotating drum 721 starts.
[0076]
That is, the blower 723 is driven so that the pressure air adjusted to the predetermined pressure is constantly blown out from the air outlet 724 at a constant flow rate, for example, and the drum driving device 722 is intermittently driven so that the rotating drum 721 is appropriately rotated at predetermined time intervals, for example. Rotate several times to promote the activity of aerobic microorganisms. In this way, the garbage (intermediate product) that is composted by fermenting and maturing to a predetermined level via microorganisms is taken out from the outlet 725 provided at the lower end of the inclined rotating body 720. .
[0077]
The raw garbage supplied to the inclined rotating body 720 by the supply device 710 is only the garbage that has been adjusted to a predetermined water content by mixing the water content adjusting material without drying by a drying device. Is also good.
[0078]
The above process is called primary fermentation, and is completed in about one day, for example, in the case where the pressurized air is constantly blown out from the air blowout port 724 and the drum drive 722 is intermittently driven. The fermented compost is stored in a maturation tank whose bottom is made of perforated metal (a perforated container), and if necessary, air is constantly blown down from below. Then, the secondary fermentation is completed. Furthermore, when the compost after the secondary fermentation is piled in a pile and alternately subjected to fermentation at around 75 ° C. and turning back after adding water, the tertiary fermentation is completed in about 4 to 5 days, for example, and the composting process is performed. Is completed.
[0079]
Next, in the garbage recycling system shown in FIG. 1, an example of a carbonization device that can be used in the carbonization step 604 is shown in FIGS.
[0080]
FIG. 14 is a front view of the garbage carbonizing apparatus, and FIG. 15A is a side view thereof. The carbonizing device 300 is rotatably provided around a center line O, and has a tubular horizontal rotary flow-down type rotary housing body provided such that the center line O can be inclined in a predetermined angle range with respect to the horizontal direction. 320. For example, a light-weight packaging material such as a vinyl chloride resin-based container and a packaging wrap material is separated and removed by a foreign matter separation device (see FIGS. 2 to 5), and a moisture content is dried by a drying device (see FIGS. 6 to 11). Prepare garbage reduced to 40 to 70%, especially to about 50%. Then, the garbage is continuously fed into the rotating housing body 320 from the higher end (the inlet 320a side) through the supply device 310 including the screw conveyor 311 and the supply cylinder 312, and carbonized. The processed garbage can be continuously taken out from the outlet 338 of the take-out part 330 connected to the lower end (the outlet 320b side).
[0081]
In FIG. 14, the center line O of the rotating housing body 320 is shown in a horizontal shape. However, in use, the rotating housing body 320 is positioned higher by the inclination angle adjusting means described later so that the supply device 310 side becomes higher. The tilt angle adjustment is performed.
[0082]
In addition to the supply device 310 and the take-out unit 330 described above, the rotating housing body 320 has a support 340 that rotatably supports the rotating housing body 320, and an inclination that changes the inclination angle of the rotating housing body 320. There are provided an angle adjusting device 350, a driving device 360 for rotationally driving the rotary housing body 320, and a heating device 370 for heating the rotary housing body 320 to a high temperature for carbonizing the garbage. It is attached to 410 in a fixed state.
[0083]
In the lower frame 400 mounted and fixed on the base (ground), the fixed shaft 354 in the vertical direction is directed toward the upper frame 410 near the outlet 320b (lower end) in the direction of the center line O of the rotary housing body 320. It is provided in a protruding shape. The upper frame 410 is rotatably connected to the fixed shaft 354 about a fulcrum shaft 353. In other words, the upper frame 410 is rotatably connected to the lower frame 400 at the entrance 320a side (higher end) about the fulcrum shaft 353 together with the rotary housing body 320 mounted thereon.
[0084]
In order to connect the upper frame 410 to the lower frame 400 so as to be rotatable about the fulcrum shaft 353, the inclination angle adjusting device 350 (this embodiment) is provided between the two frames on the entrance 320a side (higher end). Then, the screw jack 351) is inserted.
[0085]
As shown conceptually in FIG. 15B, the screw jack 351 includes a screw shaft 351a on which a male screw is formed, a screw-side receiving member 351b for screwing the screw shaft 351a forward and backward, and a female screw. On the side opposite to the side receiving member 351b, a holder 351c for rotatably holding the non-threaded portion of the screw shaft 351a, and the screw shaft 351a and the first direction so as to selectively rotate the screw shaft 351a in both forward and reverse directions. A ratchet mechanism 351d that engages with the second direction in such a manner that the screw shaft can rotate relative to the first direction and the second direction, and a screw shaft connected to the ratchet mechanism 351d. 351a is provided with a lever 351e for rotation operation protruding in the radial direction of the inner frame 351a, and the female screw side receiving member 351b is attached to the lower frame 400 via the shaft 351f and the holder 351c. And it is relatively rotatably connected to each other through a shaft 352 to the upper frame 410.
[0086]
Accordingly, when the screw shaft 351a is rotated in the jack extension direction via the lever portion 351e and the ratchet mechanism 351d from the state where the screw jack 351 is contracted, the upper frame 410 with respect to the lower frame 400 has a predetermined angle with the fulcrum shaft 353 as a fulcrum. As a result, the center line O (see FIG. 14) of the rotary housing body 320 is inclined at a predetermined angle with respect to the horizontal line. At this time, as shown in FIG. 15C, the shafts 351f and 352 allow the screw shaft 351a to be slightly inclined with respect to the horizontal line so as to keep the posture substantially perpendicular to the upper frame 410.
[0087]
As shown in FIG. 15A, the tilt angle adjusting device 350 is installed at a symmetrical position with respect to a vertical line passing through the center of rotation of the rotary housing body 320 when viewed from the center line O direction. Further, the tilt angle adjusting device 350 includes a jack having another structure such as an oil jack or a hydraulic jack in place of the screw jack 351, and a wedge device capable of moving forward and backward (the amount of advance and retreat of the wedge and the inclination angle of the rotary housing body 320). And a rotary cam device such as an eccentric cam (the rotation angle of the cam corresponds to the inclination angle of the rotary housing body 320). In addition, an angle scale for visually recognizing the tilt angle of the rotary housing body 320 or an electronic display unit for displaying the digital scale by a digital numerical value is provided or further developed, and the tilt angle and the carbonization depth (degree of carbonization) are determined in advance. From the recognized relationship, it is possible to provide a display unit that displays the inclination angle replaced with the carbonization depth.
[0088]
In any case, by adjusting the inclination angle of the rotating housing body 320, the garbage stay time in the rotating housing body 320 (the time from when the garbage is supplied to the inlet 320a to when it is discharged from the outlet 320b). ) Can be adjusted. Thereby, the degree of carbonization (carbonization depth) of the garbage can be easily adjusted.
[0089]
The support portions 340 are provided at two locations in the longitudinal direction (the center line O direction) of the rotary housing body 320, on the inlet 320a side (the supply device 310 installation side) and the outlet 320b side (the extraction portion 330 installation side). The first support portion 340A on the side of the inlet 320a rotates the plurality of (two or more) rollers 341 supported by the adjustment frame 420 forming a part of the upper frame 410 so as to be rotatable around an axis substantially parallel to the center line O. The rollers 341 are rotatably contacted with the first ring 321 fixed to the outer peripheral surface of the rotation housing body 320. That is, the first support portion 340A is configured by two rollers 341 when viewed from the center line O direction as illustrated in FIG. 15A or FIG. 16A, and the two rollers 341 rotate. It is installed at a symmetrical position with respect to a vertical line passing through the rotation center of the housing body 320, and rotates the rotation housing body 320 in the opposite direction to the rotation housing body 320 while supporting the lower part of the outer peripheral surface thereof. . More specifically, as shown in FIG. 16B, the roller 341 includes large-diameter flanges 341a on both sides, and a groove-shaped (small-diameter) rolling contact portion 341b formed therebetween has a first ring 321 provided thereon. Are in rolling contact with each other in a state where they are fitted and positioned. Thereby, the positional relationship between the first ring 321 and the first support portion 340A becomes substantially unchanged.
[0090]
Returning to FIG. 14, the second support portion 340 </ b> B on the outlet 320 b side includes a plurality (two or more) of rollers 342 rotatable about an axis substantially parallel to the center line O, and these are supported by the upper frame 410. Thus, it is in contact with the second ring 322 fixed to the outer peripheral surface of the rotary housing body 320 so as to be rotatable by friction. Similarly to the first support portion 340A, the second support portion 340B has two rollers 342 installed at symmetrical positions with respect to a vertical line passing through the rotation center of the rotation housing body 320 when viewed from the center line O direction. Then, the rotatable housing body 320 rotates in the opposite direction to the rotatable housing body 320 while supporting the lower part of the outer peripheral surface thereof (not shown). Unlike the roller 341 of the first support portion 340A, these rollers 342 have a cylindrical shape without flanges on both sides, so that the roller 342 can be rotatably supported irrespective of the axial thermal expansion of the rotary housing body 320. This point will be described later.
[0091]
Further, the rotary housing body 320 is placed on the rollers 341 and 342 of the first support 340A and the second support 340B described above, and is rotated by the driving device 360. In this embodiment, the driving device 360 is wound around the motor 361, the chain sprocket 362 of the motor 361, the annular chain sprocket 323 fixed to the outer peripheral surface on the inlet 320 a side of the rotary housing body 320, and the two sprockets 362 and 323. Although it is constituted by a chain 363 or the like, a belt, a gear, or the like may be used.
[0092]
Next, a heating device 370 that heats the rotating housing body 320 to a high temperature at which the garbage is carbonized is provided at an intermediate portion of the rotating housing body 320 in the direction of the center line O (see FIG. 17). In the heating device 370, a plurality (for example, two) of burners 371 are arranged below the rotating housing body 320 along the center line O direction, and the rotating housing body 320 is heated (increased in temperature) to heat the rotating housing body 320. The garbage flowing inside is heated from the inlet 320a toward the outlet 320b. That is, the garbage is heated from the outside of the rotating housing body 320. When the peripheral wall of the rotary housing body 320 is heated to about 800 to 1200 ° C. by the burner 371, the amount of heat is mainly transmitted from the peripheral wall of the rotary housing body 320 to the garbage by heat conduction, and carbonized in a relatively short time. You. The degree (depth) of the carbonization of the garbage is determined by the calorific value of the burner 371 as one parameter. Therefore, in the present embodiment, the degree of carbonization of the garbage can be adjusted quite precisely by appropriately combining the adjustment of the inclination angle of the rotary housing body 320 and the adjustment of the calorific value of the burner 371 described above. It is possible.
[0093]
Further, as described above, the peripheral wall of the rotary housing body 320 is exposed to a considerably high temperature. Therefore, here, the peripheral wall has a double structure, the outer peripheral wall is made of ordinary steel plate, and the inner peripheral wall is made of stainless steel plate having rust resistance and low friction coefficient. Since the inner peripheral wall is made of a stainless steel plate, it is hardly rusted and the flowability of garbage is improved.
[0094]
In FIG. 17, reference numeral 373 denotes a heat insulating material covering the heating furnace 372 surrounding the rotating housing body 320 by superposing ceramic wool or the like in multiple layers, and 374 denotes an exhaust tube of the heating furnace 372.
[0095]
Returning to FIG. 14 again, the above-mentioned second support portion 340B is provided with a thermal expansion corresponding bearing portion 380 that absorbs thermal expansion of the rotary housing body 320 in the direction of the center line O when heated to a high temperature. . Specifically, in the direction of the center line O of the rotating housing body 320, a roller that supports the second ring 322 so as to be rotatable by rolling contact than the width W1 of the second ring 322 fixed to the rotating housing body 320. The width W2 of 342 is configured to be larger. Accordingly, even if the peripheral wall of the rotary housing body 320 is heated to a high temperature of about 800 to 1200 ° C. by the burner 371 or the like and thermally expanded in the direction of the center line O, the second ring 322 is in a position of rolling contact with the roller 342. , The rolling contact state can be maintained without the engagement between the second ring 322 and the roller 342 being disengaged, so that the support of the rotary housing body 320 by the second support portion 340B is favorably maintained.
[0096]
The width W2 of the roller 342 can be determined according to the material of the peripheral wall, based on the length of the rotary housing body 320 and the heating temperature of the peripheral wall.
[0097]
A take-out part 330 fixed to the upper frame 410 by a stay 339 is provided to face the outlet 320b side of the rotary housing body 320. As shown in FIG. 18, the take-out part 330 has an opening 332 into which the outlet 320b of the rotatable body 320 enters, and has a carbonized garbage take-out port 338 formed at the tip. In addition, 333 shown in FIG. 18 is a suction port which communicates with the extraction part 330 and also communicates with the exhaust pipe 374 of the heating furnace 372 via a suction blower (not shown). The smoked gas in 330 is guided to an exhaust pipe 374 for combustion.
[0098]
A cooling unit 390 is arranged outside the rotating housing body 320 at the end on the outlet 320b side, which is the lower end of the rotating housing body 320. The cooling unit 390 can employ an appropriate cooling method such as an air cooling method or an air cooling method. Here, a water cooling method using a shower 391 which is a simple method and has a relatively high cooling effect is used. Therefore, the carbonized garbage that reaches the end of the rotating housing body 320 and is cooled from the outside of the rotating housing body 320 by the cooling unit 390 passes through the outlet 320 b and the opening 332, and from the outlet 338 of the extracting unit 330. Emitted outside the machine.
[0099]
As described above, the support portion 340A on one side in the axial direction of the rotary housing body 320 is a positioning portion (a grooved rolling contact) that restrains the supported portion of the rotary housing body 320 from being displaced by thermal expansion. Portion 341b), and the other support portion 340B is a free end (which does not restrict the supported portion in the axial direction) that allows the rotational accommodation body portion 320 to expand in the axial direction due to thermal expansion. The extension / contraction of the rotary housing body 320 due to thermal expansion is absorbed by the support on one side. This makes it possible to smoothly perform the carbonization treatment under a high temperature state without complicating the structure. In addition, by connecting this freely expandable / contractible end side of the rotary housing body 320 to a position-fixed outlet 338 for taking out the carbonized garbage so as to be able to approach / separate, a simple structure can be obtained. Removal of the processed garbage can be performed smoothly.
[0100]
The garbage carbonizing apparatus 300 configured as described above generally operates as follows. (1) The vertical movement of the screw jack 351 is adjusted, the upper frame 410 is rotated about the fulcrum shaft 353 as a fulcrum, and the inclination angle of the center line O of the rotary housing body 320 is adjusted.
(2) Adjust the calorific value of the burner 371.
(3) The motor 361 is driven, and the rotation housing body 320 placed on the rollers 341 and 342 of the support 340 is rotationally driven by the drive chain 363.
(4) The burner 371 is ignited, and cooling water is sprayed from the shower 391.
(5) A predetermined amount of the garbage dried to a predetermined moisture content is fed into the body from the high-side end (the inlet 320a side) of the rotary housing body 320 via the screw conveyor 311 and the supply cylinder 312 of the supply device 310 and the like. Supply continuously.
(6) The garbage that has been carbonized and cooled is continuously discharged from the outlet 338 of the take-out section 330 to the outside of the machine.
[0101]
The above-described operation has been described in connection with the continuous processing method in which the garbage is continuously supplied from the supply device 310 into the rotating housing body 320 and continuously discharged from the extracting unit 330. A so-called batch processing method in which (one batch) of garbage is supplied and stored to perform carbonization processing is also possible.

[0107]
FIG. 19 is a front view of the garbage eliminating apparatus, FIG. 20 is a plan view of a main part thereof, and FIG. 21 is a left side view. The extinction device 500 is provided with a horizontal storage portion 510 whose longitudinal direction is oriented substantially horizontally, and inside the storage portion 510, a bacterial carrier containing microorganisms (hereinafter, referred to as a bacterial bed) is provided. It is equipped and garbage is thrown in. A stirring member 520 for stirring the garbage and the bacteria bed is rotatably disposed in the housing section 510 with the rotation shaft 521 provided substantially horizontally, and the lower half of the housing section 510 is provided with the stirring member 520. It is formed in a semi-cylindrical shape along the tip rotation locus. Then, for example, a packaging material such as a vinyl chloride resin-based container and a wrapping material for packaging is separated and removed by a foreign matter separation device (see FIGS. 2 to 5), and a moisture content is dried by a drying device (see FIGS. 6 to 11). Is reduced to about 40 to 60% (for example, about 50%), and the garbage is substantially parallel to the rotating shaft 521, and the lower cylindrical portion is rotated when the stirring member 520 rotates the semi-cylindrical portion. From the loading portion 511 formed on the side surface (the right side surface in FIG. 21), the belt is fed into the housing portion 510 above the center in the axial direction of the rotating shaft 521 using a belt conveyor 514 (see FIG. 20) and disappears. Processing is performed.
[0108]
The extinction device 500 includes, in addition to the storage unit 510 and the stirring member 520 described above, a rotation driving device 530 that rotates the stirring member 520, and a pressurized air that is formed at least at the bottom of the storage unit 510 and is stirred in the garbage to be stirred. And an air supply device 550 connected to the air blowing unit 540 for supplying compressed air to the air blowing unit 540.
[0109]
The stirring member 520 includes a rotating shaft 521 at the center, spiral linear bodies 522 and 524 spirally provided around the rotating shaft 521 around the rotating shaft 521, and the rotating shaft 521 and the spiral linear bodies 522 and 524. Are provided in the radial direction at predetermined intervals in the axial direction. The spiral wire bodies 522 and 524 and the stirring blade portion 523 have an action of lifting and stirring the garbage and the bacterial bed to stir the garbage and the bacterial bed, so that the garbage and the bacterial bed are evenly mixed and the air supply device 550 is provided. Thus, the pressure air supplied by the method can be evenly distributed over the entirety, and gas such as carbon dioxide gas, methane gas, and ammonia gas generated by fermentation and decomposition of garbage by microorganisms can be smoothly degassed.
[0110]
As shown in FIG. 20, a plurality of helical linear bodies 522 and 524, such as two, are wound around each other like a right-handed screw and a left-handed screw in the axial direction of the rotary shaft 521 (helical direction). ) Is reversed, so that the right half and the left half of the contents (mixture of garbage and a bacterial bed) in the storage section 510 are conveyed to the opposite side in the axial direction with the rotation of the rotating shaft 521. . In FIG. 20, when the rotation shaft 521 rotates in the direction of the arrow, the contents are set so as to be conveyed so as to be separated from the center part in the axial direction toward both outer sides. Therefore, if the garbage is thrown into the center part in the axial direction from the throwing part 511, the garbage can be almost uniformly stored in the storage part 510 with the rotation of the rotating shaft 521 in the direction of the arrow. Further, if the rotating shaft 521 is driven so as to be changed between the normal rotation (first direction) and the reverse rotation (second direction), the objects can be moved not only along the circumferential direction but also along the axial direction of the rotating shaft 521 such as the horizontal direction. It is possible to move away and approach.
[0111]
The rotation driving device 530 includes a motor 531, a speed reduction device 532, and the like, and is provided in a driving device storage unit 570 adjacent to the storage unit 510. The rotation driving device 530 rotates the rotation shaft 521 of the stirring member 520 by, for example, a predetermined number of rotations at predetermined time intervals. That is, it is intermittent rotation of a fixed period. At this time, the mixture of the garbage and the bacterial bed is conveyed to the opposite side in the axial direction with the rotation of the rotating shaft 521 in the direction of the arrow, so that the entire inside of the storage unit 510 can be rapidly stirred with a small number of rotations. Can be. Further, if the motor 531 is of a reversible type as described above, the rotation direction of the rotating shaft 521 can be switched to achieve more uniform stirring. The timing and the rotation direction of the intermittent rotation of the stirring member 520 are set and adjusted in advance by a controller in the control panel 590. In addition to the intermittent rotation, the stirring member 520 may be constantly rotated at a low speed at a constant speed, or may be switched between a low speed rotation and a high speed rotation at predetermined time intervals.
[0112]
A plurality of air outlets 541 of the air blowing portion 540 into the housing portion 510 are provided. For example, a plurality of air outlets 541 are provided on the bottom of the housing portion 510 at a predetermined pitch in a direction substantially parallel to the rotating shaft 521 (in a row). A plurality of rows (three rows in the example of FIG. 20) are arranged at predetermined row intervals in the direction, and these blowing ports 541 are formed in a semi-cylindrical shape of the housing portion 510 in order to blow pressure air into the garbage to be stirred. Open to each bottom wall. The air supply device 550 that supplies the compressed air to the air blowout portion 540 includes an air compressor 551 installed in the air supply device storage portion 580 adjacent to the storage portion 510, and the air compressor 551 and a predetermined number of blowout units. It is composed of a pipe 552 and the like connecting the section 540.
[0113]
The air compressor 551 ejects the pressure air adjusted to a predetermined pressure from the air outlet 541 at a constant flow rate, for example. The timing of the intermittent ejection of the compressed air and the like are preset and adjusted by a controller in the control panel 590. The pressurized air may be jetted for several minutes at predetermined time intervals, or may be switched between low flow jetting and high flow jetting at predetermined time intervals.
[0114]
Thus, the garbage in the storage section 510 can be eliminated through the microorganisms by the stirring by the stirring member 520 and the supply of the compressed air by the air supply device 550. That is, the mixture of the garbage and the bacterial bed is supplied with appropriate oxygen (air) by the air supply device 550, so that fermentation and decomposition can be promoted.
[0115]
Next, the housing portion 510 is covered with a housing 560 so as to form a container and form a closed space, and the housing 560 receives the pressure air supplied from the air blowing portion 540 and the microorganisms of the bacterial bed. A duct 561 for guiding a gas generated when the garbage is decomposed and eliminated to the outside is connected.
[0116]
Due to the housing 560 and the duct 561, the housing portion 510 and the housing 560 are damaged by the gas pressure of gas such as carbon dioxide gas, methane gas, and ammonia gas generated when microorganisms decompose and eliminate garbage, and these unpleasant odors are generated. Can be removed to the outside without being scattered.
[0117]
A blower 562 is provided in the duct 561, and the blower 562 discharges the pressure air supplied into the housing 510 and the gas generated in the housing 510 to the outside. Further, a deodorizer 563 is connected to the duct 561 on the lower side of the blower 562, and the pressure air supplied into the storage unit 510 and the gas generated in the storage unit 510 via the deodorizer 563 are externally supplied. To be discharged.
[0118]
By the blower 562 and the deodorizer 563, the pressure air supplied into the storage unit 510 and the odor of the gas generated in the storage unit 510 can be reliably discharged to the outside without being scattered around, and the working environment can be reduced. No harm.
[0119]
Note that the deodorizer 563 may be either a device that treats odor components by chemical decomposition using an ozone generator or the like, or a device that treats odor components by physically adsorbing them using an activated carbon layer or the like. Can be used.
[0120]
Reference numeral 512 denotes a bacterial bed discharge port for removing an old bacterial bed when replacing the bacterial bed, and 513 denotes a motor for opening and closing the bacterial bed.
[0121]
The garbage extinguishing device 500 configured as described above generally operates as follows. (1) While rotating the stirring member 520, raw garbage dried to a predetermined moisture content is thrown into the upper part of the rotating shaft 521 in the axial direction from the throwing part 511 using the belt conveyor 514 or the like, and contains microorganisms. It is housed in a housing section 510 provided with a bacterial bed.
(2) The blower 562 and the deodorizer 563 are driven.
(3) The air compressor 551 is driven, and the pressure air adjusted to the predetermined pressure is constantly blown out from the air blowing unit 540 at a constant flow rate, for example.
(4) The motor 531 is intermittently driven to rotate the stirring member 520 by a predetermined number of revolutions, for example, at predetermined time intervals. In this intermittent driving, if the driving cycle (pause time) is S, and the intermittent driving time (stirring time) per operation is t, S> t, and t / S is, for example, 0.001 to 0.001. 0.05, especially about 0.005 to 0.03.
[0122]
When the fermentation / decomposition of the mixture composed of the garbage and the bacterial bed is continued under predetermined conditions, the fermentation / decomposition is completely completed and the garbage is almost eliminated. In other words, when such an extinguishing process is performed, the weight of the bacterial bed after the disappearance becomes substantially equal to the weight of the bacterial bed before the input of the garbage.
[0123]
Next, a modified example of FIG. 19 is shown in FIG. In this embodiment, the housing is divided into two parts 560a and 560b. One housing 560a is fixed on the upper part of the housing part 510, and the other housing 560b is slidably mounted on the upper end surface of the housing part 510. . When the housing 560b is closed, a closed space is formed together with the housing 560a, and when the housing 560b is slid open, the housing 510 (stirring member 520) is opened between the housing 560a and the housing 560a. A part 511 is formed. According to this embodiment, garbage can be put in a state where the upper part of the storage part 510 is opened, and the space above the storage part 510 is effectively used as compared with the case where the input part is provided on the side surface (FIG. 19). The installation area of the accommodation section 510 can be reduced. Further, since the garbage can be introduced from above the storage section 510, the volume ratio of the garbage stored in the storage section 510 can be increased.
[0124]
The duct 561 is provided so as to be displaced toward the fixed side housing 560a, and the ceiling portions of both the housings 560a and 560b are provided with a slope so as to continuously increase toward the joint with the duct 561. The generated gas flows smoothly along this slope. Note that, in FIG. 22, the same reference numerals are given to portions common to FIG. 19, and description thereof will be omitted.
[0125]
By the way, as shown in FIG. 23, in order to prevent the pressure air outlet 541 from being clogged or the like, each outlet 541 may be covered with a semi-open type cover 595. As shown in FIGS. 23A to 23C, the cover 595 is integrally provided on the inner surface of the housing portion 510 by welding or other methods so as to cover the outlet 541 in a roof shape with a predetermined gap therebetween. One end is closed with respect to the inner surface of the housing portion 510, and the other end is opened by an opening (opening) 595a.
[0126]
The form of the cover 595 is, for example, as shown in the figure, one side surface of the triangular cone is removed and the surface is fixed to the inner surface of the housing portion 510 by welding or the like (the joint portion is processed into an arc shape or the like as necessary). be able to. In addition, the rotation direction of the stirring member 520 and the fixing direction of each cover 595 (which can be said to be a clogging prevention cover or a blowing air guide cover) are associated and associated with each other, for example, as shown in FIG. , The upstream side in the rotation direction of the rotary stirring member 520 may be closed by the cover 595 (positioning the closed end), and the downstream side in the rotation direction may be opened (opening part 595a is positioned). it can. As a result, garbage and the like are less likely to enter into the outlet 541 during rotational stirring, and the cover 595 is inclined such that the amount of protrusion from the inner surface of the storage section 510 gradually increases as the cover 595 advances in the rotational stirring direction. The resistance to is small.
[0127]
In addition, when air is blown out, pressure air is blown into the mixture of the garbage and the bacterial bed from the opening 595a through the gap between the cover 595 and the inner surface of the storage section from the blowout port 541, so that the air is blown out well. In addition, the form of the cover 595 can be variously changed. In addition to the triangular cone shape, a curved shape such as a conical shape or a semi-cylindrical shape may be used. A predetermined plate member is lifted up by the supporting portion and fixed to the inner surface of the housing portion so that the plate member (roof portion) serving as the cover can receive the load such as garbage, so that the garbage becomes an open end. It is also possible to prevent such a load from being directly applied to the outlet 541.
[0128]
In the above description, as shown in FIG. 24, a plurality of blowout portions 540 are attached to the outer surface of the housing portion 510 substantially in parallel with the axial direction of the rotation shaft 521, and a common pressure air is applied to each blowout portion 540. The air outlets 540 (air introduction portions) are formed as a single unit, and a plurality of air outlets 541 are formed. 541 can also be formed.

The said annihilation device provided with a shape-like object and a stirring blade part which connects the above-mentioned rotation axis and the above-mentioned helical linear object at predetermined intervals.
[0132]
The accommodating portion has a container shape and is covered with a housing so as to form a closed space, and the housing is provided with the compressed air supplied from the air blowing portion and the microorganisms of the bacteria bed in the garbage. The extinction device to which a duct for guiding a gas generated when decomposing and extinction of the gas is introduced is connected.
[0133]

Next, in the garbage recycling system shown in FIG. 1, the garbage eliminating device described above can be used almost as it is as a feed converting device that can be used in the feed converting step 606. Invite.
[0136]
In the case where the apparatus shown in FIGS. 19 to 24 is used as a feed converting apparatus, similarly to the garbage eliminating apparatus 500, the air compressor 551 is driven so that the pressure air adjusted to a predetermined pressure is constantly supplied at a constant flow rate, for example. The jetting is performed from the blowing unit 540, the motor 531 is intermittently driven, and the stirring member 520 is rotated, for example, an appropriate number of times at predetermined time intervals. However, when used as a feed conversion device, it is generally used without adding a moisture content adjusting material (sawdust, pruning debris, rice husk, hay, etc.) so that the fermentation is stopped before the microorganisms reach the whole (usually 2). The feed is completed before the garbage disappears.
[0137]
As a result, a fermented feed containing the bacteria in a semi-ripened state is obtained. When this feed is given to livestock, its intestinal action has a deodorizing effect on feces.
[0138]
The fermented feed obtained as described above was used as livestock feed in livestock, compost was used for fertilization on farms, and charcoal was used for deodorization and soil improvement such as farms, and was further harvested on farms etc. Residues that are discarded due to consumption of agricultural products or livestock products (sales or provision of dishes) are recycled again as garbage.
