Has been filed for an organic waste treatment system (Japanese Patent Application No. 2001-18547), which is supplied to the kneading means as a processing base material for kneading with the next organic waste.
[0004]
[Problems of the Invention]
The basic problem of the present invention is to provide a system that can efficiently process organic waste in a relatively small space, and that generates less secondary waste and has less offensive odor. The object is to be able to cover the object with the processing base material (claims 1 to 3).
An additional problem in the invention of claim 2 is that no turning over is required and the aging period is shortened, and further, from the kneading of the kneaded material to the shaking of the processing base material and the carrying into the warehouse can be carried in a lump. Is to make it.
An additional object of the invention of claim 3 is to easily and uniformly sprinkle the treated base material so that the surface of the kneaded material that has been placed can be coated more uniformly.
[0005]
[Structure of the invention]
The present invention provides kneading means for kneading by providing a kneading means for kneading a treatment base material containing microorganisms with organic waste, and a warehouse for storing and aging the container holding the kneaded material for a predetermined period of time. An organic waste processing system for supplying a product to the kneading means as a processing base material for kneading with the next organic waste, wherein the processing base material is disposed on the surface of the kneaded material held in the container There is provided a swinging means for dropping and covering, and a transporting means for transporting the container so as to pass through the lower part of the swinging means, and processing by the swinging means while transporting the container by the transporting means The base material is sprinkled to cover the surface of the kneaded product with the treated base material (claim 1).
[0006]
The warehouse is preferably an automatic warehouse, but may be a rack warehouse for forklift conveyance. The container is preferably a pallet, but may be a container with an open top such as a bucket or container.
[0007]
Preferably, the container is used as a pallet, the kneaded material is placed on the pallet by the kneading means, the conveying means is constituted by a conveyor, and the kneaded material is placed at the kneading means by the lower portion of the sprinkling means. The pallet is transported to the warehouse (claim 2). This conveyor may be physically constituted by one conveyor, or may be constituted by connecting a plurality of conveyors.
[0008]
Preferably, the shaking means is provided with means for moving the dropping port of the processing base material in a direction different from the moving direction of the container (Claim 3).
[0009]
[Operation and effect of the invention]
In this invention, the processing base material containing microorganisms and the organic waste are kneaded, stored in a warehouse and aged. During this time, the organic waste is digested by microorganisms, and the matured kneaded material becomes a processing base material for kneading with the next organic waste. Since aging can be performed in a warehouse, a large amount of kneaded material can be stored in a relatively small space, and organic waste is digested by microorganisms and becomes the next processing base material, so that generation of secondary waste is reduced.
[0010]
Here, when the surface of the kneaded material placed in the container, that is, the surface of the built-up shape, is covered with the treatment base material, it absorbs or decomposes the bad odor from the kneaded material, and not only reduces the bad odor but also flies and insects. It can be prevented from smoldering. Further, the kneaded product is aged also from above, and in particular, the surface portion of the kneaded product is coated and kept warm to promote fermentation and prevent the aging of the surface of the kneaded product from being delayed. And since a process base material is dropped from a sprinkling means, conveying a container, the surface which piled up the kneaded material can be coat | covered substantially uniformly (Claim 1).
[0011]
Here, when the kneaded material is put on a pallet and aged, the aerobic fermentation is easy because the aeration is higher than the case of aging with a bucket, and reversal is unnecessary. For this reason, malodors are reduced, for example, deodorization of the air in the warehouse is unnecessary, and the aging period can be shortened. And since it can convey to a warehouse via the sprinkling means from the loading position in a kneading means with a conveyor, conveyance of a pallet becomes easy (Claim 2).
[0012]
When the processing base material is sprinkled while reciprocating or swinging the processing base material drop port of the sprinkling means in a direction different from the container or pallet transport direction, for example, in a substantially orthogonal direction, the surface of the kneaded product Thus, the processing base material can be sprinkled evenly (claim 3).
[0013]
【Example】

In these figures, 2 is an organic waste treatment system, 4 is a pit, and organic waste such as garbage is used in garbage trucks, food factories, fish processing plants, agricultural processing plants, and sewage treatment plants. From sludge tanks, paper mills, and other pipes. In the case of raw garbage, for example, it is packed in an easily decomposable plastic bag or the like and put into a pit, and food processing waste, fishery processing waste or the like is put as it is, for example, naked, and conveyed to the crusher 6 by the conveyor 5. In the crusher 6, the organic waste (for example, raw garbage such as vegetables) introduced from the upper part is sandwiched between crushing means such as a pair of rollers and a pair of gears, and dropped while crushing, and the dropped organic waste The product is received in an appropriate case and conveyed to the next kneading and setting machines 10 and 11 by the conveyors 12 and 13. In addition, since a considerable bad odor is generated when organic waste is crushed, it is preferable to deodorize the air in the crusher 6 by sending it to a deodorizing means such as the soil deodorizing unit 7.
[0014]
The kneading and placing machines 10 and 11 knead the crushed organic waste with the processing base material, and then, for example, place it on a wooden pallet with a substantially uniform thickness. The pallet to be used may be made of resin, iron, or the like that does not easily rot. Reference numerals 12 to 18 denote conveyors. The conveyors 12 and 13 convey cases containing organic waste from the crushing machine 6 to the kneading and setting machines 10 and 11, and the conveyors 14 and 15 are processed from the case automatic warehouse 42 to the processing mother. The case containing the material is conveyed to the kneading and setting machines 10 and 11. The conveyors 16 and 17 convey a pallet loaded with a kneaded product of the processing base material and organic waste such as raw garbage to the pallet automatic warehouse 24 via the shakers 20 and 21. The conveyor 18 conveys the case in the automatic case warehouse 42 to the work area 19, and the work area 19 performs operations such as replenishing sawdust to the case containing the processing base material.
[0015]
The kneading and sorting machines 10 and 11 mix organic waste such as raw garbage and the processing base material at a predetermined ratio, and the kneaded material is placed on the pallet to a substantially constant thickness, for example. The processing base material is sprinkled almost uniformly on almost the entire surface of the kneaded material so as to cover the upper surface of the kneaded material with the shakers 20 and 21. The pallet on which the processing base material is sprinkled by the shakers 20 and 21 is conveyed to the stations 31 and 32 in the automatic warehouse by the conveyors 16 and 17.
[0016]
In the automatic pallet warehouse 24, a pallet transport stacker crane 26 is caused to travel along a travel path 25 provided in the center in the longitudinal direction, and a pair of racks 28 and 29 are provided on both sides of the travel path 25, for example. A pallet on which the kneaded material is placed is placed on the shelves of the racks 28 and 29, and the kneaded material is aged on the pallet while controlling the temperature and humidity in the automatic warehouse 24 as necessary. Stations 31 and 32 for transferring the pallets to the stacker crane 26 are arranged at the tips of the conveyors 16 and 17 for conveying the pallets from the shakers 20 and 21 to the automatic warehouse 24. There is another station 33 in the automatic warehouse 24. The station 33 is provided with a conveyor, receives a pallet on which the aged kneaded material is placed from the stacker crane 26, and carries the pallet to the sieve / subdivider 40. The station 34 is a station for carrying out the compost aged in the automatic warehouse 24 from the hopper 35, and includes a conveyor.
[0017]
Reference numerals 36 and 37 denote air conditioners which air-condition the interior of the automatic warehouse 24 using the travel path 25 of the stacker crane 26 as an air passage. For example, the air conditioner 36, 37 blows outside air to ventilate the interior of the automatic warehouse 24, dehumidifies the air in the automatic warehouse 24, or adjusts the temperature of the air in the automatic warehouse 24. is there. In order to ripen the kneaded material on the pallet in the automatic warehouse 24, it is important to control the temperature and humidity. The temperature and humidity are maintained at conditions where microorganisms in the processing base material are easy to act, and the kneaded material on the pallet is kept. Aged uniformly and in a short time. Note that ventilation may be performed by opening and closing a window without using an air conditioner, and the frequency may be changed according to temperature and humidity.
[0018]
The sieve / subdivider 40 receives a pallet on which the aged kneaded material is placed from the pallet automatic warehouse 24, separates the kneaded material from the pallet and puts it on a sieve, and separates foreign matters such as metal and plastic. The kneaded material from which the foreign matter has been separated is subdivided by a predetermined amount into other uses such as kneading, sprinkling, compost production and disposal of the next organic waste with a measuring instrument. The predetermined amount here is a predetermined amount for each application, and the predetermined amount changes as the application changes. The subdivided kneaded material is stored in an appropriate case and stored in the case automatic warehouse 42. 44 is a stacker crane of the case automatic warehouse 42, 45 and 46 are, for example, a pair of racks, and 48 is a station for connecting the sieve / sorter 40 and the case automatic warehouse 42, and has a conveyor for carrying the case. Yes.
[0019]
In addition to this, the organic waste processing system 2 is provided with a parking lot, an office, a material storage, a flat storage 50 for flatly placing produced compost, and the like. In the organic waste treatment system 2 shown in FIG. 1, the layout itself is arbitrary, but the layout of FIG. 1 is suitable for a relatively small-scale organic waste treatment system provided with one pallet automatic warehouse 24, for example. ing.
[0020]
FIG. 2 shows the configuration of the kneading and serving machine 11. In the following, for convenience of explanation, it is assumed that garbage is treated, but the same applies to other organic waste. A garbage case 52 containing garbage 53 and the like is sent from the crusher by the conveyor 13. A processing base material case 54 containing the processing base material 55 is sent from the automatic case warehouse by the conveyor 15. The internal garbage 53 is dropped by chucking the case 52 with the input unit 60 and reversing the garbage case 52 by 180 °. In the crushing / feeding unit 62, the processing base material 55 is similarly dropped by chucking the processing base material case 54 and turning it 180 °. The crushing / input unit 62 is also used for crushing rice husks and the like, and therefore includes crushing rollers and gears. In other respects, the crushing and charging unit 62 is configured in the same manner as the charging unit 60.
[0021]
Reference numeral 56 denotes a pallet made of wood, iron, plastic, or the like, and preferably has a breathability improved by making the bottom part a cocoon shape or providing a mesh on the bottom part. A kneaded material 57 is placed on the pallet 56 so as to have a substantially uniform thickness so that the aging proceeds uniformly at the same speed.
[0022]
The garbage 53 and the processing base material 55 are put into a kneading unit 64, and the kneading unit 64 is provided with, for example, three screw conveyors 65 and the like. At the time of kneading, the garbage conveyor and the processing base material are transported to the right side of FIG. 2 by the screw conveyor 65, and the transported raw garbage and the processing base material are transported to the collapsing surface 66 and broken, and are kneaded during this time. At the time of serving, the screw conveyor 65 is rotated in the reverse direction to convey the kneaded material to the left side of FIG. The conveyed kneaded material falls from the hole 70 provided in the left bottom of the kneading part 64 in FIG. 2, and the pallet 56 is conveyed by the conveyor 17 from right to left in FIG. Then, the kneaded material can be placed on the pallet 56 in a uniform thickness. Here, the arrangement direction of the holes 70 is the short side direction of the pallet 56, and the conveyance direction of the conveyor 17 is the long side direction of the pallet 56, but these may be reversed, and the arrangement direction of the holes 70 and the conveyance direction of the conveyor 17 are different. What is necessary is just to be orthogonal.
[0023]
No. 68 is a nozzle, and microorganisms in the processing base material change as the garbage is repeatedly decomposed. Therefore, an aqueous solution of the same type of microorganism as that used in the processing base material is replenished at the time of kneading. It is used to prevent Moreover, it is preferable that the kneaded material 57 put on the pallet 56 has a substantially constant water content, and water may be replenished from the nozzle 68 during a dry period such as winter. The moisture content can be controlled roughly. For example, the moisture content of raw garbage is about 95% in summer and about 70% in winter, preferably about 60 to 65% after kneading and sprinkling. Further, the moisture content after aging is, for example, about 54%. Therefore, it is sufficient to replenish water at the operator's discretion without using a moisture meter. Conversely, if the water content is too high, treatment such as dehydration or drying may be performed.
[0024]
In the embodiment, two kneading and setting machines 10 and 11 are provided, and these configurations are basically the same. When composting is also produced in the kneading and serving machine 10, both the kneading and serving machines 10 and 11 are provided with a crushing and charging unit 62. In the case where compost production is not performed in the kneading and serving machine 10, the kneading and serving machine 10 may be provided with a pair of input portions 60 having no grinding function. In addition, the mechanism for performing kneading | mixing and serving with the same apparatus is not restricted to the screw conveyor 65 of FIG. For example, a screw or blade is installed in the mixer and rotated to knead, and an openable / closable hole is provided at the bottom of the mixer. When kneading, the hole is closed and the kneaded material is confined, and when serving is kneaded, the hole is opened. Should be placed out of the hole.
[0025]
FIG. 3 shows the configuration of the shaker 20, and the other shakers 21 have the same configuration. The conveyor 16 conveys the pallet 56 from the kneading and setting machine 10 to the automatic pallet warehouse 24, 72 is a hopper for feeding the processing base material, and a swinging conveyor 73 for swinging motion is provided at the outlet. The processing base material provided from the hopper 72 is conveyed to the right side of FIG. 3 by the conveyor 73 and is sprinkled almost uniformly on the kneaded material 57 from the dropping hole 74 at the tip. Since the conveyor 73 swings, the processing base material is sprinkled so as to cover the entire surface of the kneaded material 57 with a substantially uniform thickness, and the thickness to be sprinkled is equal to the thickness of the kneaded material 57 (for example, about 40 cm thick). For example, about 1/10. Then, while the pallet 56 is conveyed to the left side of FIG. 3 by the conveyor 16, the dropping hole 74 moves so as to be substantially orthogonal thereto, and the processing base material is sprinkled almost uniformly on the kneaded material 57.
[0026]
FIG. 4 shows the configuration of the sieving / dividing machine 40. The pallet 56 on which the aged kneaded material 57 is placed is conveyed from the station 33 by the conveyor from the station 33. The pallet 56 is chucked in the reversing and charging machine 80 and reversed by, for example, 180 °, whereby the kneaded material 57 falls into the hopper 82. A sieve 84 such as a vibrating sieve is provided on the outlet side of the hopper 82, and a metal piece or a plastic piece that cannot pass through the mesh of the sieve is removed and discharged from the duct 89 to the foreign material container 90. The kneaded material that has passed through the sieve 84 enters the measuring device 88 from the hopper 86 and is divided into units for next kneading, next shaking, compost production, and the like. The case is stored in the automatic case warehouse 42 by a conveyor. Note that the amount of processing base material is different for kneading, shaking, and compost production, and the amount corresponding to each application is measured and subdivided by a measuring device 88.
[0027]
FIG. 5 shows an organic waste treatment process in the embodiment. Organic waste such as raw garbage thrown in from the pit is crushed by a crusher, and the generated bad odor is treated by a soil deodorizing section or the like. The crushed organic waste is transported to a kneading and setting machine, and the processing base material weighed in an amount for kneading is transported through a conveyor from the case automatic warehouse and kneaded with the crushed organic waste. At this time, in order to compensate for the alteration of microorganisms, an active solution comprising a microorganism solution is added as necessary, and water is replenished in the dry season.
[0028]
In the kneading / slicing machine, kneading is first performed by reversing the rotation direction of the screw conveyor using a single kneading device, and then the pallet is scaled. When the pallet is transported by a conveyor and then placed by a kneading and placing machine, it can be automatically placed to a substantially uniform thickness. The pallet loaded with the kneaded material passes through the lower part of the shaker by a conveyor, and the processing base material is sprinkled almost uniformly on the surface. The processing base material used for the shake is also stored in the case automatic warehouse for each case, and is conveyed to the shaker by a conveyor and sprinkled.
[0029]
The pallet sprinkled with the processing base material is received by a conveyor into a pallet automatic warehouse, and is automatically placed and stored on a predetermined shelf in the rack. As a specific example, the amount of organic waste per pallet is about 150 kg, and the moisture content is about 70% in winter and about 95% in summer. The processing base material added by the kneader is mainly an aged kneaded material, and its volume is, for example, about 1000 liters. When the processing base material is insufficient, the amount may be increased with sawdust, rice straw, wheat straw, rice husk, bark (wood skin) or the like. Further, the mixing ratio of the organic waste and the treated base material is preferably about 3 to 20 liters of the treated base material per 1 kg of the organic waste. The water content of the kneaded product is about 60 to 65%, and water is replenished in winter so that the water content becomes this level. The thickness of the kneaded material on the pallet that has been arranged is, for example, 40 cm, and the thickness is preferably about 10 cm to 80 cm, particularly preferably about 20 to 60 cm in order to ensure air permeability and perform uniform fermentation without turning over. And
[0030]
The sawdust in the treated base material enhances the air permeability of the kneaded product, retains microorganisms, etc., and absorbs the generated bad odor or rot. The kneaded mixture of the treated base material and the organic waste is digested with nutrients by microorganisms to make it odorless and harmless. In fact, it hardly smells after being sprinkled with the treated base material.
[0031]
Further, in the shaker, for example, a processing base material of about 100 liters is sprinkled on the surface of the kneaded product. The treated base material here is an aged kneaded material itself, but when the amount is insufficient, sawdust or the like may be added, and when the microorganisms are aged or deteriorated, an aqueous solution of microorganisms may be added. In the automatic pallet warehouse, ventilation, dehumidification, and temperature adjustment are performed by the air conditioners 36 and 37, and the temperature in the automatic warehouse is slightly higher than the outside temperature due to fermentation heat when the kneaded material is digested by microorganisms. By controlling the ventilation amount, the air-conditioning is air-conditioned to a substantially constant temperature, and an increase in humidity due to evaporation from the kneaded material is prevented.
[0032]
In the automatic pallet warehouse, the kneaded product is aged for about two weeks, organic waste such as garbage is digested by microorganisms in the treated base material, and because of aerobic fermentation, the amount of bad odor generated is small. During the first week during this period, the kneaded mixture is heated to about 70 ° C., the high-temperature bacteria are activated, proteins, saccharides, cellulose, etc. are decomposed, and in the next week the temperature drops to near room temperature and lignin, etc. Slowly decomposed components are decomposed. This fermentation is an aerobic fermentation on a pallet, and the generation of ammonia, hydrogen sulfide, and the like is slight due to increased aeration by sawdust and the like. Further, a bad odor such as ammonia generated in a minute amount is adsorbed and decomposed by the processing base material sprinkled on the surface of the kneaded product. Further, by sprinkling the treated base material, aging from the upper surface of the kneaded material is promoted, and the aging of the kneaded material is accelerated as a whole. In addition, by sprinkling the treated base material, the upper surface of the kneaded product is kept warm, and the kneaded material near the upper surface is prevented from being cooled by ambient air and delayed fermentation. Furthermore, if the main part of the pallet is made of wood, or the bottom of the pallet is shaped like a cocoon, or a mesh is provided on the bottom, the kneaded product can be ventilated from above and below. Furthermore, since it arrange | positions on a pallet, unlike the case where it arrange | positions to a bucket etc., the air permeability from a side surface direction can also be acquired. Then, air is supplied to the kneaded product by aeration from the upper and lower gaps between the pallets and the travel path of the stacker crane. For these reasons, aging of a large amount of garbage can be completed uniformly and in a short time.
[0033]
The kneaded material hardly smells after the treated base material is sprinkled. The aged kneaded product is about 1100 liters per pallet, the volume hardly changes, the water content is about 54%, and is slightly dryer than the water content 60 to 65% at the time of kneading. Pathogens and plant seeds are killed when heated to about 70 ° C. at the beginning of fermentation and are harmless. The aged kneaded product is odorless and harmless, and there is almost no decomposable organic matter. The aged kneaded product is sieved by a sieve / divider to remove foreign matter. Subsequently, the kneaded material that has passed through the sieve is weighed by a measuring device, weighed by a predetermined amount for the next kneading and shaking, and stored in a case automatic warehouse. This predetermined amount is, for example, 1000 liters for the next kneading, 100 liters for sprinkling, and if digestion has progressed too much and the total amount does not reach 1100 liters, replenish sawdust etc. to make the total amount 1100 liters .
[0034]
When extracting an aged kneaded product for other uses such as compost production, add almost the same amount of fibers such as sawdust to the total amount of kneading and sprinkling for 1100 liters. . And the ratio of the circulation utilization in the organic waste processing system for kneading or sprinkling is, for example, 50% or more, preferably 70% or more, and particularly preferably 70 to 90%. When there is no other use such as compost production, 100% is recycled for kneading or sprinkling. The treated base material weighed for kneading is supplemented with fibers such as sawdust as needed before kneading and re-stocked in a case automatic warehouse. Then, the case is carried out by a conveyor to a kneading and serving machine, kneaded with raw garbage, and used for the next processing of raw garbage.
[0035]
When the compost production process is shown in FIG. 6, since the demand for compost (compost) varies significantly depending on the season, the production amount of compost also varies seasonally. Therefore, until compost production is required, the excess of the aged kneaded material is subdivided for compost and stored in a case automatic warehouse. When compost production is not carried out for a relatively long period, the aged kneaded material is recycled in its entirety. For compost production, rice husk etc. is added and kneaded and pulverized at the crushing and charging part of the serving machine, and nutrients such as chicken manure, cooking oil and rice bran are added appropriately to knead the treated base material and rice husk etc. , Place on a pallet.
[0036]
When the rice husks are crushed, considerable dust is generated, and the crushed rice husks are easy to fly and have poor storage properties. Moreover, since it is a small-scale organic waste treatment system 2, the same apparatus is used for kneading and serving for both garbage and composting. The processed base material kneaded with rice husk and added with nutrients is stored in an automatic warehouse using the same pallet, aged for about one week, the aged compost is discharged from the hopper, stored in a flat place, etc., and shipped. .
[0037]
In the embodiment, the input organic waste is made odorless and harmless in the organic waste treatment system 2, and the amount of foreign matter such as metal or plastic is reduced to waste. In addition to this, compost is produced, but this can be used effectively rather than waste. As described above, in the embodiment, organic waste can be treated almost in a closed manner, the generation of bad odor is small, and aging can be performed while efficiently controlling in a three-dimensional automatic warehouse. Can be processed uniformly in a short time.
[0038]
Although the examples have been explained mainly on the treatment of garbage, marine waste, food processing waste, livestock waste, forestry waste, manure, organic sludge such as activated sludge and sludge, beverage waste and fallen leaves, pruning The same applies to waste, sawmill waste, paper mill waste, and the like. In the embodiment, since aerobic fermentation is used, the generation of malodor is small, and the processing base material is sprinkled so that the fly and insects do not come close, and the organic waste can be decomposed in a short time in about two weeks. In addition, the burden on the environment such as the generation of CO2 and the generation of dioxins is small, the equipment cost is small, and treatment such as incineration, denitration, desulfurization, and dust removal is unnecessary, so the operation cost is low. The aged kneaded product can be reused in the treatment system, and the secondary waste is little, and the secondary waste is harmless and odorless and can be used for composting.
[0039]
[Modification]
7 and 8 show a variation of the shaker 100. FIG. 102 is the tip, 104 is a drop hole, 106 is an eaves, and 108 is a handle. The tip portion 102 and the handle 108 have a T shape as a whole. Reference numeral 110 denotes an oscillating means for oscillating the tip portion 102 to improve the fluidity of the processing base material, but it is not particularly necessary to provide it.
[0040]
As shown in FIG. 8, the bottom of the tip 102 is inclined from the center to both ends so as to be higher at the center and lower at both ends, and the eaves 106 are higher at the center and lower at both ends. The processing base material sent from 108 is uniformly dropped from the dropping hole 104 at both the center and both ends so that the surface of the kneaded material 57 can be uniformly coated.
[0041]
The pallet 56 on which the kneaded material 57 is placed in the kneading section passes through the lower part of the shaker 100 by the conveyor 16 and is conveyed to a station of an automatic warehouse. When the pallet 56 reaches the lower position of the shaker 100, the gate 112 is opened and the processing base material is supplied from the handle 108 to the tip portion 102. The supplied shaking member is improved in fluidity by the vibration of the vibrating means 110, moves by the inclination from the central portion of the tip end portion 102 to both end portions, and falls while getting over the eaves 106. Then, by using the inclination and the height of the eaves 106, the processing base material is uniformly dropped at both the central portion and both end portions of the dropping hole 104.
