The work of changing the stored garbage up and down is hardly performed.
Therefore, it is difficult to evenly pulverize the garbage stored in the treatment tank, and it takes a long processing time to sufficiently pulverize and dry and proceed to the next process, which increases power consumption. Have.

Japanese Patent No. 3097639

  The present invention has been made in view of the above-described problems of the prior art, and provides a garbage processing machine equipped with a stirring means that can efficiently perform pulverization and drying processing of garbage in a short time. Is an issue.

In order to solve the above-mentioned problems, a garbage processing machine according to the present invention includes a stirring member that is driven and rotated at the bottom of a processing tank, and the stirring member that stirs and crushes garbage with the stirring member. The scissors extend in the radial direction across the center of rotation, the heights of the ends of both scissors are different, and cooperate with a fixed blade that is arranged and fixed on the inner surface of the treatment tank at the radial side end of the scissors located below. It is characterized by comprising a blade body for cutting and crushing raw garbage for operation, and further having a curved stirring rod fixed at a position preceding the blade body when the stirring member is rotated over both sides of the stirring member. you.

The stirrer only needs to have different height positions at the ends of both ends protruding in the radial direction across the rotation center axis. For example, the bases of both ends are horizontally spaced with a vertical interval. Or the lower ridges may be projected horizontally, and the upper ridges may protrude upwardly.
Fixed blades that are arranged and fixed on the inner surface of the treatment tank are arranged above and below across a trajectory along which the side edge of the lower ridge (horizontal ridge) moves, and are arranged at one place or in the circumferential direction. Arbitrary, for example, provided at a plurality of locations (for example, 3 locations).
Further, the curved stirring rod fixed over both sides of the stirring member may be a pipe having a circular or square cross section, a strip, or the like. In short, the curved stirring rod is fixed over both ends having different heights.

  According to the above means, when the stirring member rotates, the garbage collected in the treatment tank is firstly stirred by the upper bowl and the curved stirring bowl is rotated after the upper bowl passes. The garbage is moved to the bottom surface side and the peripheral surface side of the treatment tank. Then, after the curved stirring bowl passes, the lower bowl rotates on the bottom surface, so that the garbage collected on the bottom side is rubbed and crushed by the bottom face of the processing tank and the rotating lower bowl. At the same time, the garbage collected on the peripheral surface side is efficiently crushed by passing between the blade fixed to the side edge of the lower ridge and the fixed blade fixed to the inner surface of the treatment tank. Therefore, raw garbage can be efficiently pulverized in a short time.

The stirring member may be constituted by a pipe having a circular cross section, etc., but the cross sectional shape may be a pipe or bar material having a substantially equilateral triangle or an isosceles triangle, etc., and the apex may be located above the bottom. not good.

  According to the above means, the garbage can flow upward along the upward inclined surface by the rotation of the agitating member, so that the lower and upper layers of the garbage layer are effectively interchanged and stirred uniformly. be able to.

  The curved stirrer is attached so as to protrude outward from the diameter line across the horizontal and inclined ridges on the diameter line, but the shape thereof is substantially arcuate in plan view, or substantially U-shaped in plan view, and is not shown in plan view. The outer peripheral surface of the curved or bent shape is arranged close to the inner surface of the treatment tank (claim 3). Note that the shape of the curved stirring bowl in plan view is not limited to the circular arc shape formed of a continuous curve, but may be a combination of a straight line and a curved line, or a straight line discontinuity (bending).

  According to the above-mentioned means, the curved stirring bowl can be smoothly rotated while being scraped through the garbage layer by the rotation of the stirring member, and the action of moving the garbage to the bottom side of the treatment tank can be effectively performed. .

The rotation of the stirring member may be either continuous rotation or intermittent rotation in a direction (clockwise direction) in which the curved stirring rod precedes the blade fixed to the side edge of the horizontal rod, but rotation in the clockwise direction. If, but it may also be to repeat the rotation of the counter-clockwise direction alternately.

  According to the above means, the upper and lower layers of the garbage in the treatment tank are effectively stirred by rotating the stirring member alternately in the clockwise direction and the counterclockwise direction. That is, it is possible to effectively exchange the lower layer and the upper layer by disposing the garbage which has moved and accumulated on the bottom side of the treatment tank by the clockwise rotation and is rotated by the counterclockwise rotation. As a result, the garbage that accumulates on the bottom side of the processing tank and is crushed by the rotation of the stirring member is moved upward by the rotation in the counterclockwise direction, and the garbage that is not sufficiently crushed in the upper layer is moved to the bottom side. Then, it is crushed by the rotation of the stirring member.

The inclination杆側end of the stirring member is extended up to near the inner surface of said processing bath, placed in treatment vessel inner surface facing the scraper on its side edge.
According to the above means, the garbage adhering to the upper inner surface of the treatment tank can be effectively scraped off by the scraping plate that rotates the position near the inner surface of the treatment tank. Therefore, the whole garbage can be uniformly pulverized.

According to the first aspect of the present invention, the garbage processing machine is fixed to the fixed blade that fixes the garbage stored in the processing tank to the inner surface of the processing tank, and the side edge of the bowl at the lower position of the stirring member. It is possible to efficiently move to the crushing location to be crushed by the cooperative action with the blade body, so that the garbage can be crushed and dried efficiently in a short time. Moreover , the upper layer and the lower layer of the garbage can be effectively exchanged and stirred uniformly.
Furthermore, according to the structure of Claim 2 , the upper layer garbage can be efficiently moved to the bottom face side of a processing tank.

Further, according to the configuration of the third aspect, the upper and lower layers of the garbage layer can be efficiently exchanged, so that the entire garbage can be uniformly crushed.
According to the configuration of the fourth aspect , it is possible to prevent garbage from remaining on the upper inner surface of the treatment tank. Therefore, the whole garbage can be uniformly pulverized.

The drive means 11 includes a motor 11a and a power transmission mechanism (transmission) 11b that transmits the rotational force of the motor 11a to the stirring member 5. The detailed structure of the stirring member 5 will be described later.
In addition, an extraction port 12 for extracting dried garbage is provided at the lower portion of the peripheral wall of the processing tank 1, and a lid plate 12 ′ is attached to the outside of the extraction port 12 so as to be openable and closable.
The outer peripheral surface of the treatment tank 1 configured as described above is covered with a heat insulating material (not shown) to suppress heat dissipation and temperature decrease.

The lid 8 that closes the opening of the processing tank 1 is configured as a flat box having a hollow structure, and a packing 13 is attached to the lower surface 8a of the box so as to surround the upper opening of the processing tank 1. In addition, an exhaust port 14 is opened in communication with the internal space inside the position where the packing 13 is attached and within the processing tank 1, and the exhaust port 14 is directly below the exhaust port 14. A shielding plate 15 having a diameter larger than the diameter is supported in a horizontally suspended manner at a predetermined interval.
An attachment arm 16 is connected to the lid 8, and the attachment arm 16 is pivotally supported on the instrument frame 7 by a shaft 17, and a damper 18 extends between the attachment arm 16 and the instrument frame 7. It is installed and supported so that it can be opened and closed.

  As shown in FIG. 1, the shielding plate 15 may be suspended and fixed to the lower surface of the lid body 8, but when the lid body 8 is opened, the shielding plate 15 is in front of the upper surface of the processing tank 1 (apparatus). When the garbage is thrown into the treatment tank, a container (bucket or the like) containing the garbage may hit the shielding plate 15. For this purpose, the shielding plate 15 is movable, and when the lid 8 is opened, the shielding plate 15 is tilted and retracted to a position where it does not interfere with the closing operation, that is, the lid 8 side. Good.

The hot air outlet 9 is configured to discharge hot air from the upper part of the peripheral wall of the processing tank 1 in a substantially horizontal direction in order to dry the garbage stored in the processing tank 1. Specifically, a cylindrical body 9 ′ defining the hot air outlet 9 is disposed through the peripheral wall of the treatment tank 1, and a blower (blower) accommodated in the casing 7 on the opposite side of the cylindrical body 9 ′. The heater 3 is arranged in the middle of the two air passages. As a result, air (hot air) heated by the heater 3 is blown out from the hot air outlet 9 that protrudes into the treatment tank 1 through the cylindrical body 9 ′.
The blowing capacity of the blower (blower) 2 is preferably 4 m ³ / min or more if, for example, a single garbage disposal capacity is 50 kg, but even if it is less than that, moderate hot air on the garbage surface Just hit.

The exhaust port 14 has one side of an exhaust plate 14 ′ in which a cylinder having a predetermined height is integrally fixed to an auxiliary lid 8 ′ having a size capable of closing an opening 19 opened in the center of the lower surface of the lid 8. A hinge (not shown) is rotatably supported, and the opposite side of the hinge is fixed with a set screw, and the auxiliary lid 8 'is positioned directly above (downstream side) the exhaust port 14. The first filter 20 is detachably mounted. The attachment of the auxiliary lid 8 ′ to the lid body 8 is not limited to the above-described method, and any method may be used, for example, a method in which four sides of the auxiliary lid 8 ′ are detachably fixed with a set screw.
The filter 20 is discharged into the treatment tank 1, and when the hot air used for drying the garbage flows into the exhaust port 14, the dried garbage is mixed in the exhaust stream, so that the garbage is removed. It is a filter, and has a mesh shape that can remove particulate matter.

Maintenance of the first filter 20 is performed by opening the lid 8 when the lid 8 can be opened (when the drying process is not performed), and then removing a set screw for fixing the exhaust plate 14 '. By rotating about the hinge, the first filter 20 appears and the first filter 20 can be replaced.
Moreover, after opening the cover body 8, the set screw which fixes auxiliary cover 8 'to which exhaust board 14' is attached can be removed, and the 1st filter 20 can also be removed together.

  Further, a through hole 21 is formed in the back plate 8b of the lid body 8. When the lid body 8 is closed, the through hole 21 is opposed to the suction port 2a of the blower 2 installed in the casing 7. In addition, the lid 8 is configured to generate an intake action. In addition, an opening 22 is formed in the portion of the casing 7 where the air inlet 2a of the blower 2 faces, and a packing (not shown) is attached around the opening 22, whereby the through hole 21 of the lid 8 and the blower are provided. The two suction ports 2a are configured to communicate with each other. A wire mesh (not shown) is attached to the opening 22 to remove dry garbage mixed in the exhaust flow.

The blower port 2b of the blower 2 is connected to a box 3 'provided with a heater 3, and the outlet of the box 3' is branched in two directions, one of which is a hot air outlet 9 for supplying hot air to the processing tank 1. The other end is connected to an exhaust pipe 23 that opens into the atmosphere. The exhaust pipe 23 is provided with a pre-deodorizer filter (second filter) 24 and a deodorizer 4 in the direction of the exhaust port, and between the pre-deodorizer filter (second filter) 24 and the deodorizer 4. This pipe is provided with an exhaust adjustment valve 25 for adjusting the flow rate of the exhaust.
The deodorizer 4 is a platinum catalyst type deodorizer generally known today.
With the above-described configuration, a circulation path is formed by the processing tank 1, the blower 2, and the heater 3, and the other branched downstream from the heater 3 is opened to the atmosphere, deodorized, and exhausted to the atmosphere. .

Next, the stirring member 5 for crushing raw garbage put into the treatment tank 1 will be described.
The stirring member 5 includes a horizontal rod 10 extending horizontally in one of the radial directions across a shaft portion fixed to an output shaft (power transmission mechanism 11b) of the driving means 11 that drives and rotates the stirring member 5, and the horizontal rod It is composed of an inclined rod 10 ′ that extends in an upwardly inclined shape from the same height position as the starting end position in the opposite direction of the radial direction. That is, the stirring member 5 as a whole is formed in a shape in which the top and bottom of the “he” is reversed.

  The horizontal rod 10 and the inclined rod 10 ′ constituting the stirring member 5 are pipes (or rods) having a substantially equilateral triangle cross section, and are arranged so that the apex is located above the bottom. In addition, the cross-sectional shape of the pipe constituting the stirring member 5 is not limited to a substantially equilateral triangle, but may be a substantially isosceles triangle. In this case, the apex is arranged so as to be located above the bottom.

A blade body 26 having a substantially inverted L-shaped cross section is fixed to the tip of the horizontal rod 10 with the tip of the horizontal piece 26a facing the inner surface of the processing tank 1, and the tip of the inclined rod 10 ' A scraper plate 27 is fixed substantially parallel to the inner surface of the treatment tank 1.
The blade body 26 fixed to the tip of the horizontal rod 10 passes between a pair of upper and lower fixed blades 28 arranged on the inner surface of the processing tank 1 with a predetermined interval in the vertical direction and shifted in the circumferential direction. Is arranged. The fixed blades 28 are arranged and fixed at a plurality of locations (three locations in the drawing) on the inner surface of the processing tank 1 at intervals in the circumferential direction. The interval between the tip of the blade body 26 and the inner surface of the treatment tank 1 is set to an interval at which the crushing effect is exhibited. If the interval is large, the crushing effect is small, and if the interval is small, the garbage is clogged, causing a problem that hinders the rotation of the stirring member 5. For example, the distance between the tip of the blade body 26 and the inner surface of the processing tank 1 is about 25 mm, and the distance between the scraping plate 27 and the inner surface of the processing tank 1 is about 15 mm.

Further, the curved stirring rod 29 is arranged so as to rotate ahead of the blade body 26 when the stirring member 5 rotates in the clockwise direction across the horizontal rod 10 and the inclined rod 10 'of the stirring member 5. It is fixed.
The curved stirring bowl 29 is curved and formed into a substantially semicircular arc shape in plan view using a round pipe having a circular cross section, and one end thereof is bent substantially perpendicularly downward and fixed on the apex near the rotation center of the horizontal bowl 10. The other end is connected and fixed to the outer surface (slope) near the tip of the inclined rod 10 '. As a result, the semicircular arc-shaped portion of the curved stirring rod 29 protrudes to one side (left side of the stirring member in this embodiment (FIG. 5)) with the stirring member 5 as the center, and the inclined stirring rod 10 from the connection point with the horizontal rod 10. It is attached so as to have an upward slope toward the connection point.

  Further, the curved stirring bowl 29 is arranged so that the arc portion near the connection point with the inclined bowl 10 ′ is close to the inner surface of the processing tank 1. The space between the inner surface of the processing tank 1 and the closest part of the arc portion of the curved stirring bowl 29 is, for example, about 40 mm.

  When the stirring member 5 configured as described above is driven and rotated by the driving means 11, the garbage stored in the processing tank 1 is moved between the bottom surface by the horizontal basket 10 rotating horizontally on the bottom surface of the processing tank 1. When the horizontal basket 10 passes through the lower layer portion of the garbage, the garbage is agitated on the slope of the horizontal basket 10. Further, since the inclined rod 10 ′ of the stirring member 5 is inclined upward toward the peripheral wall of the treatment tank 1, it is uniformly stirred so that the lower, middle and upper layers of the garbage are mixed. Then, since the scraper plate 27 fixed to the tip of the inclined rod 10 'rotates in the vicinity of the inner surface of the peripheral wall of the processing tank 1, the garbage remaining on the upper peripheral surface of the processing tank 1 is scraped off and dried without being crushed. The generation of garbage to be processed can be eliminated.

  Further, due to the rotation (clockwise direction) of the stirring member 5, the curved stirring rod 29 is rotated prior to the horizontal rod 10, and the curved stirring rod 29 is directed upward from the horizontal rod 10 side toward the inclined rod 10 ′. Because of the inclination, the middle to upper layer garbage is moved to the bottom surface side of the processing tank 1 by the curved stirring bowl 29. That is, by rotating the stirring member 5 in the clockwise direction, the garbage is turned into the garbage in the order of the upper part of the processing tank → the peripheral wall of the processing tank → the bottom surface of the processing tank → the space between the curved stirring bowl 29 and the stirring member 5. A flow is generated such that the garbage moves in a substantially vertical direction with respect to the treatment tank 1, and the garbage moves from the upper part to the lower part of the treatment tank. And the garbage which moved to the lower part (bottom side) of the processing tank is between the blade 26 fixed to the horizontal paddle 10 that rotates following the curved stirring pad 29 and the fixed blade 28 fixed to the processing tank 1. Gather and crush with a double-edged blade.

  Further, when the stirring member 5 is rotated counterclockwise, the garbage in the processing tank is bent in the order of the bottom of the processing tank → the peripheral wall of the processing tank → the upper part of the processing tank → the space between the curved stirring bowl and the stirring member 5. A flow is generated such that the garbage moves in a direction substantially perpendicular to the processing tank 1 around 29, and the garbage moves from the lower part to the upper part of the processing tank. That is, when the rotation direction of the stirring member 5 is reversed, the flow direction (moving direction) of the garbage generated around the curved stirring rod 29 is also reversed.

  Accordingly, the stirring member 5 may be rotated in one direction, for example, only in the clockwise direction. However, by alternately repeating the clockwise direction and the counterclockwise direction, the garbage is disposed in the upper part of the processing tank 1. The garbage that regularly flows between the bottom and the lower part of the treatment tank moves to the upper part, and the garbage that has not been sufficiently crushed on the upper part is replaced by the lower part and moved again. It is processed. By repeating this, the garbage in the treatment tank can be efficiently and evenly crushed. As a result, the treatment time can be shortened and the power consumption can be saved.

The present invention is not limited to the illustrated embodiment, and can be changed as appropriate without departing from the scope of the invention.
(1) The pair of upper and lower fixed blades 28 that are fixed to the inner surface of the peripheral wall of the treatment tank 1 are arranged so as to be shifted in the circumferential direction, but they may be arranged at positions that overlap each other.

It is good also as a form.
(3) The stirring member is not limited to a shape in which one (lower ridge) is horizontal and the other ridge (upper ridge) is inclined, and the height of the end portions of both ridges may be different.
