DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to garbage and marine products, seaweeds, starfish, cut grass, and the like generated at homes and restaurants.
The present invention relates to a continuous decomposition apparatus for organic waste, in which various unnecessary organic wastes such as weeds, wood chips, sawdust, straw and the like are fermented and dehydrated and dried.

[0002]

2. Description of the Related Art Conventionally, municipalities generally collect organic waste such as garbage generated at home and the like, and treat it by incineration and landfill. However, such a treatment method requires not only a large incineration facility cost, a facility cost for treating combustion gas and odor, a personnel cost, and the like, but also a restriction on a landfill site. In addition, in each household or the like, the organic waste must be stored until the day when the local government collects the organic waste, and sealing work for deodorization and the like is troublesome. Therefore, it is desired that each household or the like treat organic waste.

Conventionally, in order to treat organic waste at home or the like, the organic waste is pulverized by a disposer or the like, or the organic waste put in a treatment tank is transferred by a screw and compressed, or the organic waste is centrifuged. Things were being dehydrated.

[0004] In other countries, for example, kitchen garbage generated at home is crushed by a disposer and is discharged into a sewer. However, in Japan, sewage pipes are not only thin and may be clogged, but the absolute capacity of sewage treatment capacity is insufficient, and in some areas, sewage facilities are not widely used. Can not be adopted. Even if the above-mentioned treatment method is adopted, garbage generated at home is several times higher in nutrients than human waste, that is, carbohydrates such as starch, protein,
Because of its fat content, Japan, which has a high population density, has a problem in that if it is discharged into rivers, lakes, or the sea, it will contaminate them.
Therefore, even if the organic waste is pulverized, compressed, or dehydrated as described above, in the end, the municipal government has to rely on the refuse disposal, saving labor, reducing the cost of the municipal waste, preventing air pollution, etc. Can not contribute to.

In order to solve the above problems, in recent years,
Various batch-type (solid fractionation) decomposition treatment apparatuses have been proposed in which organic wastes are fermented by microorganisms and composted (Japanese Utility Model Application Laid-Open No. 63-140037, Japanese Patent Laid-Open No. 4-4).
084).

[0006]

However, in the above-mentioned conventional decomposition treatment apparatus, the added organic waste is mixed with the organic waste being fermented in one treatment tank, so that the added anaerobic waste is added. Aerobic microorganisms and aerobic microorganisms and aerobic microorganisms and anaerobic microorganisms adhering to the organic waste itself are mixed, and the balance of fermentation is disrupted, and it is difficult to keep the growth environment conditions of microorganisms constant. , Cannot be composted efficiently. In addition, the organic waste introduced immediately before being taken out as compost is insufficiently fermented, or tends to emit a bad smell when the inlet of the treatment tank is opened. In addition, since new organic waste cannot be introduced without removing composted waste, multiple units must be prepared, which not only increases equipment costs but also requires a large installation space. I do.

[0007] Unless the fermentation rate of the organic waste is increased as described above, it is not possible to input the next new organic waste or to shorten the cycle for removing the composted processed material. It is necessary to throw wood chips every time waste is thrown in, to heat with an electric heater, or to blow hot air, which not only involves inconvenience, but also requires extra energy and equipment, It will be expensive. In addition, if the fermentation is forcibly conducted rapidly, a large amount of bad odor is generated at one time, so that ventilation and odor prevention measures are required, and the cost is further increased. Further, the processed material cannot be reliably crushed and discharged, and handling of the processed material after discharging is troublesome.

[0008] The present invention is to solve the conventional problems as described above, the organic waste is decomposed and fermented by microorganisms, the water is removed and dried, so that municipalities can collect waste. It can save labor, reduce costs, effectively use landfills, prevent air pollution by incineration, etc., as well as recycle organic waste as liquid fertilizer and fertilizer for effective use. The organic waste is dewatered to reduce its volume, and the organic waste is arranged from the discharge port side toward the inlet port in the oldest order, so that a large amount of organic waste can be continuously decomposed at once. Organic waste continuous fraction that can be economically promoted and efficiently treated without the need for extra energy or equipment. It is an object to provide a processing apparatus.

The insertion ports 12 and 15 are inserted through holes formed in the top plate 7 and are opened to the outside of the outer box 1, and each protruding end is opened and closed by opening and closing lids 19 and 20. The drain port 13 and the drain port 14 are inserted into holes formed in the partition plate 16 and open to the lower chamber.

On the bottom plate 2 of the outer box 1, a liquid storage container 21 and a storage container 22 are removably stored. Liquid storage container 21
The opening 23 communicates with the drain port 13 through a flexible pipe 24 made of rubber or the like.
5 communicates with the outlet 14. The discharge port 14 is opened and closed by an opening / closing lid 26 as needed. Outlets 27 and 28 are formed below the end plate 6 of the outer box 1 and below the position of the side plate 3 near the end plate 6, and the outlets 27 and 28 are opened and closed by opening and closing lids 29 and 30. It has become.

A transfer screw 31 is provided in the processing container 8. Both ends of the stainless steel screw shaft 32 of the transfer screw 31 are connected to the end plates 10, 1, 1 of the processing vessel 8.
1, a rotatable handle 35 is attached to a protruding end of the screw shaft 32 on the end plate 10 side. The transfer screw 31 is set such that the outer diameter of the plastic screw blade 36 is substantially equal to the inner diameter of the processing container 8. Therefore, by operating the handle 35, the transfer screw 31 is rotated, and the organic waste input from the input port 12 can be transferred to the front of the processing container 8 by the screw blade 36, that is, to the discharge port 14 side. Further, the screw blade 36 can serve as a lid for the transferred organic waste. The screw blade 36 has one or more holes (having a diameter of 5 mm to 50 mm) on the downstream side in the organic waste transfer direction.
mmφ) 37 is formed. At the tip of the screw shaft 32, that is, at the discharge port 14 side, the blade 3
8 are attached. An exhaust pipe 39 communicates with the top plate 7 of the outer box 1 on the front end side of the processing container 8.

In this embodiment, the diameter of the processing vessel 8 is 300
mm, length 1100mm, volume 70 liters, pitch of screw blade 36 200mm, diameter 300m
mφ.

The above configuration will be described in further detail below, together with the usage thereof. The organic waste continuous decomposition treatment apparatus of the present invention is installed in a home garden or the like, and before use, the opening / closing lid 19 is removed in advance and the input port 12 is opened, and about 10 liters of humus in which a large amount of microorganisms inhabit is supplied to the input port 12. And into the processing container 8. After the charging, the handle 35 is operated to rotate the transfer screw 31, and the humus is slightly transferred to the front in the processing container 8, that is, to the discharge port 14 side. Then, unnecessary organic waste such as garbage is supplied to the input port 12.
Then, the transfer screw 31 is rotated by operating the handle 35, the organic waste is slightly transferred to the inside of the processing container 8, and the input port 12 is closed by the opening / closing lid 19. When the organic waste is generated in this way, the organic waste is charged into the processing container 8 from the input port 12 in the same manner as described above, and is sequentially transferred little by little by rotating the transfer screw 31. It should be noted that the humus only needs to be charged first, and then only unnecessary organic waste needs to be charged. Further, the humus and the organic waste to be charged in the initial stage may be sent from the beginning to the back side of the discharge port 14 side, but thereafter, there is a possibility that the organic waste to be charged is compressed when sent to the back side. Therefore, it is preferable to feed in little by little.

When water is contained in organic waste such as garbage, the water flows down along the inclined surface of the processing vessel 8, passes through the drainage port 13 through the pipe 24, and flows into the storage vessel 21.
Stored inside. The organic waste transferred to the front of the processing container 8 starts to be decomposed by microorganisms attached to itself, inoculum inhabiting the mulch, and moderate moisture, oxygen and temperature. The liquid fertilizer produced by the decomposition also flows down along the inclined surface of the processing container 8, and is discharged from the drain port 13 to the pipe 24.
And is stored in the liquid storage container 21 and fermentation is continued in the liquid storage container 21. In this manner, excess water in the processing vessel 8 is removed, the moisture content of the organic waste being decomposed is automatically adjusted, and microorganisms useful for decomposition are easily propagated. Fermentation can be performed, and generation of unnecessary methane gas and the like can be prevented. On the other hand, gas and water vapor generated during the fermentation and leaked into the outer box 1 from the exhaust port 17 and the like rise along the inclined outer wall of the processing container 8,
It is discharged from the exhaust pipe 39 to the outside of the outer box 1.

There are many types of microorganisms such as molds, yeasts, bacteria, etc., and there is a huge amount in a wide distribution. And
While repeating the decomposition and mineralization of organic waste, a cycle in which various microorganisms grow and disappear and another microorganism grows is repeated. In addition, when environmental conditions are different, organic waste is decomposed and mineralized by microorganisms of different groups. By utilizing this property, the decomposition and mineralization of organic waste can be continuously processed using one processing container 8 and the transfer screw 31. That is, the organic waste put into the processing container 8 is fermented sequentially from the old organic waste, and is decomposed and mineralized. In this process, even if one microorganism dies, another microorganism propagates, and the surviving microorganisms migrate to the next newly input organic waste, propagate and start to decompose the organic waste.

As described above, since the inner diameter of the processing vessel 8 is substantially equal to the outer diameter of the screw blade 36, the organic waste which is charged first in the processing vessel 8 and sequentially transferred to the other side,
The old waste products that have been decomposed and mineralized are sequentially sent toward the outlet 14 without being mixed with the organic waste that has been introduced later. During this time, the input organic waste contains trimethylacine like fish, and particularly when the odor is strong, the opening / closing lid 20 is removed and the input port 15 is opened, and the activated carbon is charged into the processing container 8 from the input port 15. You may make it deodorize. Further, the exhaust pipe 39 may be provided with a deodorant such as activated carbon to deodorize. In addition, when the organic waste is excessively packed in the front end portion of the processing container 8, the transfer screw 31 may be loosened by rotating the transfer screw 31 in the opposite direction.

Also, by forming one or more holes 37 at the tip of the screw blade 36, when the organic waste decomposed at the tip in the processing vessel 8 becomes a certain pressure or more,
Not only can the backflow from this hole 37 reduce the extrusion pressure of the organic waste by the transfer screw 31, but also the organic waste being decomposed and the demineralized processed material after decomposition can be put into the hole 37 to form a powder. The air can be supplied through the holes 37 to facilitate the growth of aerobic microorganisms, the gas and water vapor can be easily removed from the holes 37, and the decomposition efficiency of organic waste can be increased. it can.

In the case of microorganisms, especially aerobic microorganisms, oxygen needs to be supplied for their growth.
When the organic waste is pushed in at step 1, a gap is formed on the back surface of the screw blade 36, and the gap continues spirally toward the inlet 12, so that air can flow in, and further, gas,
Water vapor can be exhausted.

The disassembled, dried and fertilized material is crushed by the crushing blade 38 at the tip by rotating the transfer screw 31 by operating the handle 35, and the opening / closing lid 26 is removed to remove the outlet 14. From storage container 22
The storage container 22 can be taken out of the outer box 1 through the outlet 27 by removing the opening / closing lid 29 as necessary. Then, the processed material is extracted as a fertilizer such as agricultural crops, horticulture, vegetation, etc. containing a suitable amount of nitrogen, phosphorus, etc. with as little water as possible, or is reduced in weight, collected, incinerated,
You can either remove it as landfill waste, choose the most economical or convenient method, and remove it when you need it. At this time, the outlet 14 may be always closed by the opening / closing lid 26 or the outlet 14 may be opened by removing the opening / closing lid 26 according to the degree of drying of the processed material or the degree of fertilization.

If the temperature is low in winter and the composting is insufficient when taking out the processed material, natural stone, zeolite, activated carbon, wood chips, etc. containing fermentative microorganisms and enzymes are added to promote the fermentation. You may make it do.

On the other hand, the opening / closing lid 30 is removed, the liquid storage container 21 is taken out from the outlet 28, and is generated during decomposition of the organic waste.
By diluting the liquid fertilizer stored in the liquid storage container 21 by 100 to 1000 times with water, it can be used as a fertilizer for agricultural products, horticulture, plants and the like. The liquid fertilizer may be treated with activated sludge to purify eutrophic water, or may be purified using plants or plankton and flown to a sewer or drain.

In order to continuously ferment the organic waste as described above and to process the required amount of input and discharge without the need for labor, the length of the processing container 8 (organic waste) is required. L, the effective diameter of the screw blade 36 of the transfer screw 31 is D, the pi is π, the pitch of the screw blade 36 is P, and the number of crests of the screw blade 36 is N. Desired.

[0030]

(Equation 1)

Then, the processing container 8 and the transfer screw 3
The shape 1 is such that the ratio L / D of the length L and the diameter D of the processing vessel 8 is 3 or more, and the pitch P and the diameter D of the screw blade 36 are different.
Is preferably 1 or less.

For example, in the case of a family of four in a general household, unnecessary organic waste such as garbage of an average of 1 kg or less per day is generated, and 1 kg of the organic waste is discharged daily under a natural condition at a temperature of 20 ° C. to 40 ° C. In order to continuously perform fermentation treatment under the following conditions, it is preferable to set the volume of the processing container 8 to 10 liters to 300 liters from conditions such as pH during fermentation of organic waste, fermentation heat, and supply amount of oxygen. For example, as in this embodiment, the processing container 8
Is set to 70 liters, as described above,
In order to treat an average of 1 kg of organic waste per day, it is possible to reduce the volume by dehydrating and fermenting and decomposing the organic waste in order, and the average temperature is about 1/5 in about 3 months at an average temperature of 20 ° C.
Since the volume can be reduced, it can be stored for 70 days or more.

Next, a second embodiment of the present invention will be described. 3 and 4 show an apparatus for continuously decomposing organic waste according to a second embodiment of the present invention. FIG. 3 is a partially cutaway side view of a main part, and FIG. 4 is a sectional view taken along line BB of FIG. It is.

In this embodiment, as shown in FIGS. 3 and 4, at the intermediate portion of the transfer screw 31, instead of the screw blade 36, the inlet 12 (see FIG. 1) side and the discharge port 14 (see FIG. A plurality of switching blades 40 (in the illustrated example, three at every 120 degrees) are provided for switching the organic waste transferred toward the reference) side. That is,
A fermentation zone in which the inside of the processing vessel 8 has a screw blade 36 on the input port 12 side, and a screw blade 36 on the discharge port 14 side.
, And a switching zone having a switching blade 40 at an intermediate portion. The fermentation zone is set so as to be 1/3 or more of the total length. Other configurations are the same as those in the first embodiment.

° C is the optimum temperature. Here, in the fermentation zone, part of the energy when the microorganisms breathe inside the organic waste pushed by the screw blades 36 is dissipated as heat and has heat inside the organic waste. Activity becomes active. This heat is transferred to the screw blade 36
Can act as a wall to prevent heat from escaping outside, even in winter.

In addition, the fibers of organic wastes, especially fibers of turfgrass and defoliation, are decomposed by thermophilic and anaerobic cellulase-decomposing bacteria (bacteria and filamentous fungi). Blocked conditions are desirable, and the screw blades 36 can accomplish that purpose. On the other hand, anaerobic microorganisms desirably have a high moisture content. In this fermentation zone, the water is blocked by the screw blades 36 and the moisture is hard to evaporate.

Then, after the fiber has been decomposed and the heat has dropped, the organic waste is thinly cut by the turning blades 40, the bulk specific gravity of the organic waste is reduced, and the organic waste is softened to provide a condition under which microorganisms are easily activated. In addition, by reducing the bulk specific gravity of the organic waste by turning over, unnecessary moisture is caused to flow down along the inclined inner surface of the processing container 8 or is evaporated from a gap at the upper part of the processing container 8, and carbon dioxide gas or the like is removed. It can be discharged from the gap at the top of the processing container 8.

In the extrusion zone, the organic waste sent from the cutback zone is a treated product in which the decomposition of fiber and lignin is progressing, especially in the case of turfgrass and defoliation.
Alternatively, it can be sent to the outlet 14 as a processed product after the decomposition.

By the above process, the organic waste is continuously converted into air suitable for the activity of microorganisms at each stage.
Conditions such as moisture and temperature can be given as timely as possible to promote treatment such as reduction of organic waste.
