[Prior art]
In a conventional garbage processing machine in which raw garbage thrown into a stirring chamber is treated with soil bacteria while stirring, there are those that decompose or fertilize by repeating ventilation and stirring.
[0003]
[Problems to be solved by the invention]
Garbage is generated every day where people are present, so it is necessary to treat it so that it does not remain. Among the treatment methods, the method of utilizing soil bacteria can decompose garbage or make it into fertilizer.
However, when using this soil fungus, stirring the garbage in a ventilated treatment room serves the purpose of increasing the aerobic soil fungus activity and increasing the treatment efficiency. Carbon dioxide and water vapor generated in this way can be easily discharged, but it is difficult to discharge moisture adhering to garbage without delay. There is a problem that processing may become impossible. For this reason, it becomes necessary to replace the soil fungus support material every several months, and the running cost becomes high.
Moreover, there is also a problem that even if it is converted to fertilizer, there is no takeover and there are cases where the processing is troubled.
[0004]
The present invention has been made to solve such a conventional problem, and the object of the present invention is to ventilate even moisture that is added together with raw garbage and moisture that is excessively generated by decomposition. Providing a garbage disposal machine that can efficiently dehumidify through the combined use of forced dehumidification and maintain a high degree of decomposition of soil bacteria to enable continuous decomposition of garbage and can be used economically. There is.
[0005]
[Means for Solving the Problems]

In the garbage processing machine according to the first aspect of the present invention, the stirring blades agitate the garbage in the stirring chamber, and hot air of fresh air is supplied from the warm air fan into the stirring chamber. When the supplied hot air is caught in the garbage, the temperature rise of the garbage and the gap between them and the oxygen supply to the aerobic soil fungus in the garbage are continuously and sufficiently performed. The warm air is controlled so that the stirring chamber has an appropriate temperature.
The aerobic soil fungus obtains the controlled atmosphere and actively decomposes garbage into carbon dioxide and water. Further, the air collected from the agitation chamber is aerated in a deodorizing tank to remove odors and the like and discharged to the outside.
[0008]
As described above, in the garbage processing machine according to claim 1 of the present invention, moisture that is introduced together with the garbage and moisture that is sequentially generated by decomposition is excessive from the warm air blower.

Next, the operation of this embodiment will be described.
In the garbage processing machine of the present embodiment, first, the driving blades 5 and 5 cause the stirring blades 4 and 4 to stir the garbage introduced from the inlet 12 together with the base material, for example, about one rotation per minute. . At this time, depending on the characteristics of the garbage, there are various directions such as the direction in which the blades bite the garbage from the top, the direction to bite the garbage from the bottom, or the same direction, one is stopped and the other is forward or reverse, and the other is intermittently rotated. Can be stirred into form.
Moreover, the warm air machine 6 supplies the fresh warm air which heated external air to high temperature to the heating chamber 18 from the opening part 22b. The hot air is supplied to the stirring chamber 2 and the upper space 11 through the passage 19 after filling the heating chamber 18. Accordingly, the garbage in the stirring chamber 2 is heated from the outside of the stirring chamber and maintained at, for example, 60 ° C., and the warm air is wound inside by the stirring blade 4.
Soil fungi are heated together with raw garbage and actively decompose and decompose the raw garbage into carbon dioxide gas and water. The humidity of the part 11 becomes high. Further, the air in the upper space is in a state in which a large amount of the odor of garbage and the amount of carbon dioxide generated during decomposition is contained.
[0015]
During the decomposition of the garbage, the suction pump 28 and the liquid pump 9 are also driven at the same time, and the suction pump 28 contains a large amount of the odor and carbon dioxide gas of the garbage through the suction cylinder 27. The air is collected and aerated by the nozzle 23 of the deodorization tank 7 to be purified air and discharged from the exhaust port 29 to the outside. At this time, the deodorizing liquid is deprived of temperature from the exhaust air in addition to the heat radiation from the outer wall of the deodorizing tank 7.
The liquid pump 9 circulates the deodorizing liquid in the deodorizing tank 7 to the dehumidifying device 8. Since the temperature of the deodorizing liquid is lower than the heated air temperature of the upper space portion 11, the dehumidifying device 8 condenses moisture in the air in the upper space portion that is in contact with the pipe, and is collected by the drain pan 25 to be It discards in the deodorizing tank 7 from the opening part 26. FIG.
For this reason, the water | moisture content in the stirring chamber 2 does not become excess, and can maintain the decomposition | disassembly effect | action by a soil microbe favorably.
[0016]
As described above, in the garbage processing machine according to the present embodiment, in addition to the stirring action, the heating action, and the decomposition action, the forced dehumidification action is repeatedly performed repeatedly, so that Efficient removal of excess water due to the water that is sequentially generated by decomposition and decomposition makes it possible to maintain the decomposition function of soil bacteria at a high level and to efficiently decompose garbage continuously. .
Since the base material is dried and the soil fungi are activated by continuous operation, the base material can be continued by additional supplementation about once a year and can be used economically.
Further, since the dehumidifying device 8 communicates with the deodorizing tank 7 and is provided with a liquid pump 9 for circulating the deodorizing liquid between the deodorizing tank 7, a Freon gas compressor, an evaporator and the like are not required, and the dehumidifying device 8 is removed. The apparatus can be provided economically and lightly.
In addition, since the agitating blades 4 are arranged in two horizontal directions with their axes parallel to each other and each has a dedicated drive unit 5, an optimum form of agitation is performed depending on the type and characteristics of the garbage and the garbage is decomposed. Effects such as efficient processing can be obtained.
