DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus for decomposing garbage (garbage) generated in a kitchen by the action of microorganisms.

[0002]

2. Description of the Related Art As a method for treating kitchen waste generated daily in kitchens such as ordinary households and restaurants, there is a method utilizing decomposition by microorganisms. This method is useful for reducing the amount of garbage, can contribute to the reduction of the treatment load in garbage incineration plants and sewage treatment plants, and is attracting attention as being desirable from the viewpoint of environmental conservation.

[0003] As this type of kitchen waste treatment apparatus, a compost container has been conventionally known. This is a cylindrical container with a lid plate on one side opening, and is used by embedding it in the soil with the opening on the other side facing downwards in a suitable length, opening the lid plate and throwing garbage inside, It is configured to leave the lid closed and decompose the input garbage into compost by the activity of microorganisms that propagate in the soil.

[0004] However, composting containers require the presence of soil for embedding, which is a prerequisite for use. In addition, since the decomposition of kitchen garbage inside is slow, a large-volume container is required to increase the throughput. The unpleasant odor generated due to decomposition leaks into the surrounding area, making it unsuitable for use in urban areas where there are many condominiums such as condominiums and apartments. In urban areas, it is difficult to handle compost generated by decomposition. There is also a problem.

A garbage disposal apparatus which solves these problems, utilizes decomposition by microorganisms, and can be used in an urban area is disclosed in Japanese Patent Application Laid-Open No. 4-156959 and the like. An application has already been filed. The garbage processing apparatus for which the present applicant has already filed, stores a processing medium suitable for culturing microorganisms using porous wood chips in a processing tank having an appropriate internal volume, and processes the garbage. The inside of the tank is maintained in an environment (temperature, humidity, etc.) suitable for propagation of microorganisms such as worms such as worms, nematodes and protozoa, and fungi such as cocci and bacilli. Is arranged.

This mixing means is constituted, for example, by rotatably supporting a stirring wheel embedded in a processing medium around a horizontal axis so as to be rotatable. They are mixed. The mixed garbage can be disposed of in the processing medium maintained in a good environment by the activity of various microorganisms. H ₂ O)
And carbon dioxide (CO ₂ ), which can be released to the atmosphere, and has the advantage that it is not necessary to dispose of the product.

[0007]

By the way, in such a conventional garbage processing apparatus, a space connected to the garbage input port is formed above the processing tank to receive the garbage into the processing tank between the top plate and the processing board. However, since the environment such as temperature and humidity is favorable in this space, eggs such as flies and the like attached to the garbage may hatch, breed, and jump out when the garbage is thrown.
As a countermeasure, a heater is arranged in the space,
A configuration has been proposed in which insects are maintained at a high temperature of 50 ° C. or higher, and a volatile insecticide is disposed. However, such a method has a problem that a sufficient insecticidal effect cannot be expected when the pests are sneaking into the processing medium.

The present invention has been made in view of the above circumstances, and an object of the present invention is to use a combination of a pest attracting means and a pesticidal means to attract pests lurking in a treatment medium. It is an object of the present invention to provide a garbage disposal device capable of reliably extermination.

[0009]

According to the present invention, there is provided a garbage disposal apparatus in which mixing means is disposed inside a processing tank for storing a processing medium, and the garbage which is put into the processing tank from above by the operation of the mixing means. Is mixed with the processing medium, and the garbage processing apparatus is decomposed by the activity of microorganisms that propagate in the processing medium. The garbage processing apparatus faces the space above the storage area of the processing medium inside the processing tank, and attracts insects and kills insects. Means are provided.

[0010]

According to the present invention, this makes it possible to attract pests lurking in the processing medium into the space and kill the insects, so that the pests in the processing tank can be reliably exterminated and contribute to the decomposition of kitchen garbage. It has little effect on power worms, fungi, etc.

The peripheral edge is locked to a locking claw 35d provided on the mounting plate 35b to be detachably attached to the slide plate 30. The net 36 may be simply made of synthetic resin, and a sheet or the like impregnated with an insecticide may be attached along the inside thereof. Note that an attractant such as a pheromone of various insects may be used instead of the moth lamp 35.

On the rear side of the pivot portion of the cover plate 33, a storage room is formed, which is surrounded by a cover plate 60 attached to the top plate 3, and inside the storage room, a microprocessor is used. Operation control unit 6 is stored. The operation control unit 6
And its peripheral circuit are integrally coated with a resin mold such as urethane resin, and prevent corrosion caused by gas generated inside the processing tank 1 due to decomposition of kitchen garbage described later and moisture inside the processing tank 1. I'm doing it. Above the cover plate 60, an operation panel (not shown) provided with a switch for operation operation, a display unit for displaying an operation state, and the like is provided.

As shown in FIG.
A drain portion 10 is formed around the periphery by the partition plate 11.
The drainage section 10 is connected to the outside by a drainage port 12 penetrating the peripheral wall of the treatment tank 1, and is connected to a drainage pipe for sewage (not shown) by a drainage pipe 14 connected to the drainage port 12 via a joint 13. Have been. The partition plate 11 surrounding the periphery of the drainage unit 10 is formed of a perforated metal plate such as a punching metal, and transmits water generated in the processing medium 2 in the process of kitchen waste treatment described later, and While preventing the medium 2 from falling off, the weight of the processing medium 2 containing water can be supported.

Inside the processing tank 1, a stirrer 7 is disposed above the storage area of the processing medium 2. Stirrer 7
Is configured such that a plurality of agitating blades 71 project radially outward at appropriate intervals in the axial direction on an agitating shaft 70 that is rotatable about a substantially horizontal axis. A motor box 80 is provided on the upper inside of the processing tank 1, and the drive motor 8 is housed inside the motor box 80.
The output shaft of the drive motor 8 and the stirring shaft 70 penetrate one side wall of the processing tank 1 and protrude to the outside of the same, and are connected by a drive chain 81 wound therebetween.

As described above, the stirrer 7 is located above the storage area of the processing medium 2, and the storage area of the processing medium 2 includes an upper area A in which the stirring is performed by the stirring blades 71, 71. The lower region B is set to be larger than the upper region A, as is apparent from FIG.

Inside the processing tank 1, a heater tube 9 containing a heater H is mounted horizontally and slightly below the rotation range of the stirring wheel 7. Electricity is supplied according to the command to generate heat, and the surrounding processing mediums 2 are heated.

The operation of the apparatus of the present invention configured as described above is performed by opening the cover plate 33 covering the front upper part of the top plate 3, putting the garbage on the slide plate 30, closing the cover plate 33, and then closing the cover plate 33. An operation switch (not shown) arranged on the rear cover plate 60 is turned on.

In response to the ON operation of the operation switch, the operation control unit 6 issues a drive command to the drive motor 8 for a predetermined time, and drives the drive motor 8 to rotate. As described above, the driving force of the drive motor 8 is transmitted to the agitator 7 via the drive chain 81, rotates inside the processing tank 1, and the garbage is removed from the processing medium 2.
Mixed with. In addition, it is possible to reliably introduce the kitchen waste into the treatment tank 1 by flowing water on the slide plate 30 after the kitchen waste is charged.

The stirrer 7 has a plurality of normal rotations (rotation in the direction indicated by the arrow in FIG. 2) and a short time reverse rotation in accordance with a drive command from the operation control unit 6. Repeat several times.
Each of the stirring blades 71 has a curved shape, so that the garbage introduced into the processing tank 1 and dropped onto the processing medium 2 is drawn inward in the radial direction at the time of the forward rotation, and is mixed while being pushed outward at the time of the reverse rotation. At the same time, during this time, it is gradually crushed by collision with the stirring wheel 7 and the inner wall of the processing tank 1 to form fine crushed pieces, which are substantially uniformly dispersed throughout the upper region A.

After the above-described operation of putting the garbage, the waiting state is maintained until the next garbage is put in, and the garbage mixed in the processing medium 2 is decomposed during this waiting state. During this time, for example, the operation control unit 6 issues an energization command to the heater H based on the detection result of the internal temperature of the processing medium 2 to heat the processing medium 2, and also issues a drive command to the drive motor 8 at predetermined time intervals. And a short-time stirring by the stirring wheel 7 is performed.

The processing medium 2 in the processing tank 1 is a microorganism culture base material that forms an environment suitable for propagation of microorganisms as described above. The temperature in the processing medium 2 depends on the activity of the microorganisms themselves and the heater H. The temperature is maintained at a temperature suitable for the propagation of microorganisms by appropriate energization of the. Therefore, in the processing medium 2 inside the processing tank 1, various microorganisms brought along with the garbage propagate, and the garbage is decomposed by the activity of these microorganisms during the standby state. Since the garbage in the processing medium 2 has been crushed by the rotation of the stirring blades 71, 71,... After being charged, the decomposition processing is performed in a relatively short time.

During the disassembly of the kitchen garbage, the moth lamp 35 is turned on constantly or periodically to attract insects such as flies breeding in the treatment tank 1 and bring them into contact with the net 36, thereby killing the insects. It can be exterminated, and the inconvenience of fly or the like breeding in the treatment tank 1 jumping out when throwing garbage into the kitchen can be eliminated. The net 36 is exchanged regularly.

Microorganisms that propagate in the treatment medium 2 include rotifers,
Insects such as nematodes and protozoa, and fungi such as cocci and bacilli are classified roughly, and the garbage in the processing medium 2 is converted into saccharides by predation of the worms which are active in an aerobic environment. , Amino acids and organic acids, and then into the final products water and carbon dioxide by the activity of the fungus in an anaerobic environment.

A part of the generated water is taken into the processing medium 2 and acts to maintain a humidity suitable for the propagation of microorganisms, and most of the remaining water flows down in the processing medium 2 to form the partition plate 11.
Penetrates into the drain section 10, drain port 12, joint 13
And discharged into the sewage through the drain pipe 14. On the other hand, the generated carbon dioxide gas rises in the processing medium 2, flows out into the upper space of the processing tank 1, and is provided on the rear side of the top plate 3 by the operation control unit 6.
The air is discharged to the atmosphere via an exhaust port (not shown) juxtaposed in the storage space.

In the above-described embodiment, the structure in which the moth lamp 35 and the net 36 for insecticide are attached to the lower surface of the sliding plate 30 is shown. However, the present invention is not limited to this. Of course it is good.
