Description

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 composting garbage such as garbage generated in a home kitchen or a commercial kitchen by aerobic fermentation decomposition, and more particularly to an aerobic fermentation decomposition. The present invention relates to a structure for taking out composted garbage in an apparatus provided with a fermenter for performing fermentation and an aging tank for further promoting aerobic fermentation decomposition in addition to the fermenter.

[0002]

2. Description of the Related Art Composting of garbage is accomplished by fermenting and decomposing organic matter in the garbage with the aid of microorganisms. This fermentation generally employs an aerobic fermentation decomposition method in which oxygen is added to the processed product for fermentation because of advantages such as high fermentation heat obtained during fermentation and little generation of malodor accompanying fermentation. ing. In order to promote this aerobic fermentation, it is necessary to prepare an optimum environment for the activity of microorganisms. It is necessary to maintain the water state and the like, supply oxygen necessary for fermentation, and maintain an appropriate temperature.

[0003] For this purpose, a conventional general garbage disposing apparatus includes, in addition to a fermentation tank, a stirring means for equalizing the state of the whole processed material put into the fermentation tank, oxygen supply, and the like. The apparatus is provided with a ventilation means for adjusting the water condition and a heating means for keeping the temperature inside the fermenter at a certain value.

By the way, the fermentation time may be long depending on the components contained in the garbage. For example, fibrous plants and the like are hardly subjected to fermentation degradation in a fermentation tank, so that considerable time is required for complete fermentation degradation. Therefore, in addition to the fermentation tank, there has been proposed an apparatus having a configuration in which a fermentation tank for fermenting and degrading garbage fermented and decomposed in the fermentation tank to ripen plant fibers and the like is added (for example,
JP-A-9-253614, JP-A-10-5732
No.). The configuration disclosed in the above publication is separated from this fermentation tank in addition to a fermentation tank provided with a heating means and a stirring means, and an aging tank provided with stirring and scraping-out stirring means therein is provided. These tanks communicate with each other via an opening formed in the partition wall. further,
The ripening tank is provided with an opening for taking out the ripened processed product, and a collecting means for collecting processed garbage is disposed below the opening. Through the opening located between the fermentation tank and the ripening tank and the opening formed in the ripening tank, the processed product can be moved to another position by overflowing.

[0005]

In the above-mentioned apparatus, the stirring means provided in the fermentation tank and the ripening tank are stirred while crushing garbage by stirring blades supported coaxially. However, the following problem arises because the stirring means located in the aging tank is set to have the same radius of rotation as the stirring means located in the fermentation tank. The stirring means in the fermenter has a large stirring radius in order to enable a large amount of stored garbage to be decomposed. Therefore, if the stirring radius in the fermentation tank is the same as that of the fermentation tank, the distance between the processed material removal opening provided in the fermentation tank and the bottom of the fermentation tank becomes longer, and the distance accumulated at the bottom is increased. It takes time for the processed material to overflow from the removal opening. Furthermore, since the processed material from the maturation tank overflows from the take-out opening and is introduced into the recovery means, it depends on the amount of overflow regardless of artificial removal. Unnecessary overflow may cause the processing unit to become full by the collection unit and overflow the processing unit into the apparatus. Also, if the collection means is enlarged to prevent such overflow of the processed material, it will take time and effort to transfer the collected processed material to another container such as a bag, and it is necessary to easily perform the transfer. Becomes difficult. In addition, since the aging tank is configured to take out the processing material existing through the taking-out opening to the outside, the processing material that cannot overflow from the taking-out opening will remain, so the aging tank is emptied. It is difficult to clean the inside.

SUMMARY OF THE INVENTION In view of the above problems in the conventional garbage processing apparatus, an object of the present invention is to provide an apparatus having a plurality of processing tanks, namely, a fermentation tank and an aging tank, without increasing the size of the apparatus. An object of the present invention is to provide a garbage disposal apparatus having a configuration that can be easily and quickly taken out.

[0007] Another object of the present invention is to provide a garbage disposal apparatus having a structure capable of easily performing the work of transferring the processed material taken out of the aging tank to another container or the like.

[0008]

Means for Solving the Problems In order to achieve this object, the invention according to claim 1 further comprises a fermentation tank for performing fermentation decomposition while stirring garbage, and a processed product fermented in the fermentation tank. A fermentation tank for fermenting by agitation while stirring, and a garbage disposal apparatus in which a transfer opening is formed between the tanks so that the processed material overflows and is movable. The height of the bottom of the maturation tank is set higher than the height of the bottom of the fermentation tank by reducing the stirring radius in the maturation tank with respect to the stirring radius, and the processed material in the maturation tank is located near the bottom of the maturation tank. And a collecting means for collecting the processed material in a space below the bottom of the ripening tank between the vicinity of the taking-out opening and the bottom of the processing apparatus main body.

According to a second aspect of the present invention, in the garbage disposal apparatus according to the first aspect, the collecting means has a dust-like configuration and is disposed in a space below a bottom of the aging tank. And

[0010]

According to the first aspect of the invention, the height of the bottom of the fermentation tank can be made higher than the bottom of the fermentation tank by setting the stirring radius of the fermentation tank smaller than that of the fermentation tank. Thus, a space for accommodating the collecting means can be formed below the bottom of the aging tank, so that it is not necessary to increase the size of the apparatus in order to secure an installation space for the collecting means.
In addition, since the opening for taking out the processed material is provided near the bottom of the aging tank, the processed material can be taken out in the direction of gravity only by opening the opening. Furthermore, since the processed material can be taken out in the direction of gravity, the processed material remaining in the maturation tank can be almost completely taken out to the outside, so that the state in which the maturation tank is empty can be easily obtained, and the cleaning operation is simple. Can be done.

According to the second aspect of the present invention, since the collecting means is formed in a dust-like shape, the processed material taken out of the aging tank can be directly transferred to another container or the like, thereby causing scattering. It can be easily transferred without any change.

The stirring shaft 6 is provided with a plurality of stirring blades 6A for fermentation tanks inside the fermentation tank 2 and a plurality of stirring blades 6B for maturation tanks inside the ripening tank 3 along the axial direction. The bases of the stirring blades 6A and 6B are fixed at equal positions in the circumferential direction of the stirring shaft 6. As shown in FIG. 2, of the stirring blades 6A and 6B, the aging tank stirring blade 6B has a smaller stirring radius than the fermentation tank stirring blade 6A.

As shown in FIG. 2, the fermenter 2 comprises a fermenter bottom plate 2B arranged near the bottom plate of the apparatus main body 1A, the side cover 2A and the partition wall 4, and constitutes an accommodation space for processed products. On the lower surface of the bottom plate 2B of the fermenter, a heater (not shown) serving as a heating means for maintaining a temperature required for fermentation decomposition of the processed product and a heat insulating material (not shown) for preventing heat radiation to the outside are provided. ) Is arranged.

On the other hand, as shown in FIG. 2, the aging tank 3 has a lower stirring radius than the fermentation tank bottom plate 2B because the aging tank stirring blade 6B has a smaller stirring radius than the fermentation tank stirring blade 6A. A certain aging tank bottom plate 3B, a side cover 3A, and a partition wall 4 constitute an accommodation space for the processed material. In this embodiment, the ripening tank bottom plate 3B is a ripening tank stirring blade 6B.

Since the present embodiment has the above configuration,
When a processed material such as garbage is put into the fermenter 2, the stirring shaft 6 is driven to rotate, and the stirring blade 6 A for the fermenter rotates to perform crushing and stirring of the garbage, and the heat from the heater is used. A fermentation decomposition process is performed. When the fermentation decomposition process proceeds in the fermenter 2, the fermented product is scraped up from the state of being deposited on the bottom 2 B of the fermenter in the direction of rotation of the stirring blade 6 A for the fermenter, and is transferred to the partition wall 4. It is transferred into the aging tank 3 by overflowing from the opening 4A.

In the aging tank 3, the treated product is stirred and aged by the stirring blades 6B for the aging tank, and an aged product corresponding to the final residue is obtained. Since the ripened product is deposited on the bottom of the ripening tank 2, when the take-out opening 3B2 is opened by the take-out shutter member 8, the ripened product is dropped toward the take-out container 9 and collected. Take-out container 9
Can be transferred to another container by pulling out the take-out container 9 from the apparatus main body 1A. At this time, the tip of the take-out container 9 can be inserted into the container. There is no scattering.

On the other hand, since the processed material in the aging tank 3 can be dropped and discharged from the removal opening 3B2,
All elimination can be performed without the need for a special elimination operation, so that the inside of the aging tank 3 can be cleaned without any processed material.

According to the above-described embodiment, since the processed material deposited in the ripening tank 3 can be taken out by free fall, the processed material deposited in the ripening tank 3 can be removed. The processed material can be collected from the aging tank 3 before overflowing from the upper surface of the tank 3.

[0022]

According to the first aspect of the present invention, the height of the bottom of the fermentation tank is higher than the bottom of the fermentation tank because the stirring radius of the fermentation tank is smaller than that of the fermentation tank. Can be. Thus, a space for accommodating the collecting means can be formed below the bottom of the aging tank, so that it is not necessary to increase the size of the apparatus in order to secure an installation space for the collecting means. In addition, since an opening for taking out the processed material is provided near the bottom of the aging tank, the processed material can be taken out in the direction of gravity simply by opening the opening, and the time required for taking out can be reduced. Will be possible. Furthermore, since the processing object remaining in the aging tank can be almost completely taken out by removing the processing object in the direction of gravity, it is easy to obtain a state in which the aging tank is emptied, and to perform cleaning work and the like. Maintenance work can be performed easily.

According to the second aspect of the present invention, since the collecting means is formed in a dust-like shape, the processed material taken out of the aging tank can be transferred to another container or the like as it is, and scattering can be prevented.
