Opening toward the upstream side in the direction of rotation, it passes through the communication holes 32, 32. It will fall to the side, that is, the lower part of the processing tank 1. At this time, the rotation direction of the screw blades 5 is a direction accompanied by the downward movement as described above, so that the downward pushing force acts on the processing medium 2 and the processing medium generated through the communication holes 32, 32 ... 2 fall is promoted.

The stirring pad 6 which rotates with the lower part of the processing tank 1 as a rotation range by the rotation of the stirring shaft 50 has a function of stirring the processing medium 2 falling through the dividing plate 3 to the lower part and uniformly dispersing it over the entire surface. Eggplant At the lower part of the processing bath 1, there is provided a take-out port 7 which penetrates the peripheral walls of the inner bath 1b and the outer bath 1a and opens to the outside of the exterior housing H.
A lid 8 is detachably attached to the. FIG. 4 shows a state in which the lid 8 is removed, and at this time, the processing medium 2 in the lower part of the processing tank 1 can be easily taken out to the outside through the taking-out port 7.

Inside the outer housing H, a heater chamber 13 is formed so as to face the lower part of the processing tank 1. Inside the heater chamber 13, a heater plate that generates heat by power supply from a power source (not shown) is formed. 14 is arranged by being crimped to the bottom surface of the processing tank 1 by the spring force of the pressing spring 15. In addition, the heater chamber 13
An air pump P as an air supply means is fixed to the lower part of the inside of the heater chamber 13 with a discharge port.

The stirring shaft 50 is a hollow shaft as shown in the drawing with a part cut away, and horizontal holes are formed above and below the processing tank 1 and open in the heater chamber 13. The supply air introduced into the heater chamber 13 by the operation of the air pump P is heated by the contact with the heater plate 14, and the stirring shaft 50

In the apparatus of the present invention constructed as described above, the upper lid 4 is opened, and the garbage to be treated is put into the treatment tank 1 through the opening in the upper part, and then the upper lid 4 is closed to hermetically close the treatment tank 1. Used. After that, for example, when an operation switch (not shown) is operated, the stirring motor M is driven for a predetermined time, the processing medium 2 is stirred on the upper side of the dividing plate 3 by the rotation of the screw blades 5, and the processing medium 2 is put into the processing tank 1. The kitchen waste is taken into the processing medium 2.

At this time, since the rotation of the screw blades 5 is carried out in the upward direction, the stirring of the processing medium 2 is carried out along with the movement in the axial direction, and the garbage is evenly distributed in the processing medium 2. It is dispersed and decomposed by the activity of microorganisms inhabiting the treatment medium 2. Further, during this period, the processing medium 2 does not drop to the lower part of the processing tank 1, and the garbage is decomposed at the upper side of the dividing plate 3 (upper part of the processing tank 1).

The air pump P is driven constantly or at predetermined time intervals, and sucks the outside air and supplies the inside of the processing tank 1 through the above-mentioned path. This supply air is introduced into the processing tank 1 through heating by the heater plate 14 inside the heater chamber 13 and is aerated through the processing medium 2, and then the dividing plate 3
Is discharged to the lower part through the communication holes 32, 32 ... And is discharged to the drain tank T ₁ through the discharge pipe 10 and the connection pipe 11.

That is, the kitchen waste in the processing medium 2 is decomposed under the condition that an appropriate temperature is maintained by the heated air supply as described above and a sufficient amount of oxygen is supplied. The water and gas generated by this decomposition are sent out to the lower side of the dividing plate 3 together with the air supply, and are discharged to the drainage tank T ₁ via the discharge pipe 10 and the connection pipe 11.

Inside the drainage tank T ₁ , water having a depth capable of burying the tip of the connecting pipe 11 is stored, and the produced water discharged together with the supply air and the produced gas is the tip of the connecting pipe 11. The gas that is captured in the drainage tank T ₁ together with the outflow from the gas and is simultaneously discharged is purified by aeration in water.

A drainage tank T arranged in parallel with the drainage tank T _1.
The _second, upper part of the gas in the waste water tank T ₁ is introduced through the communication pipe 12, the moisture contained in the gas is trapped in the drain tank T _2, the gas introduced at the same time, the aeration in water It is purified and discharged to the outside air through a discharge port (not shown). That is, by installing the _two drainage tanks T ₁ and T ₂ , it is possible to reliably collect the water content in the exhaust gas and to sufficiently purify the gas released to the outside air.

The screw blades 5 are designed so that they can be reversed by a user's operation.
The process is performed every predetermined period (several weeks or months) set based on the necessary time for exchanging the processing medium 2. When such a reversal occurs, the processing medium 2 in the upper part of the processing tank 1 drops to the lower part through the communication holes 32, 32 ...
Is flattened by the rotation of and is deposited on the bottom surface of the processing tank 1 (inner tank 1b).

The processing medium 2 below the processing tank 1 is the lid 8
Can be quickly taken out to the outside of the exterior housing H from the take-out port 7 that opens as shown in FIG. 4, and then the upper lid 4 is opened and the same amount as the taken-out processing medium 2 is added. By replenishing the treatment medium 2 from the upper part of the treatment tank 1, the exchange of the treatment medium 2 can be completed easily and hygienically.

As shown in FIG. 1, it is desirable that the processing medium 2 below the processing tank 1 be left with an appropriate deposition depth even during the normal operation for decomposition treatment. That is, the gas discharged to the lower part containing the water produced by the decomposition treatment in the upper part of the treatment tank 1 contains organic matter such as untreated garbage particles, and when the treatment medium 2 is present in the lower part, The exhaust gas passes through the processing medium 2 and is exhausted to the exhaust pipe 10. On the other hand, the heating by the heater plate 14 is
Since 14 is directly performed from the bottom surface of the processing tank 1 to which pressure is applied, the internal temperature of the processing tank 1 has a higher distribution in the lower side of the dividing plate 3 than in the upper side, and the inside temperature of the processing medium 2 deposited as described above. Microorganisms have a high activity.

Therefore, the organic matter contained in the exhaust gas is decomposed by the activity of the microorganisms inhabiting the treatment medium 2 while being aerated through the treatment medium 2 below the treatment tank 1, and the exhaust pipe 10 The exhaust gas discharged to the exhaust gas is purified, and the gas finally released to the outside air is sufficiently purified by this cleaning action and the cleaning action in the two drainage tanks T ₁ and T _2. As a result, adverse effects on the surrounding environment due to odor emission can be reduced as much as possible.

The communication holes 32, 32 ...
Is not limited to the formation mode shown in FIG. 2 and FIG.
Although other forming modes may be adopted, the communicating holes 32, 32 ... Shown in FIGS. 2 and 3 have an effect that they can be easily formed by cutting and bending the plate material forming the dividing plate 3.

Further, in this embodiment, the screw blade 5 is provided as the stirring means inside the processing tank 1, but the present invention can be applied to a structure using other stirring blades which rotate around the vertical axis. It goes without saying that the same effect can be obtained. However, when the screw blades 5 are used and the openings of the communication holes 32, 32 ... Of the dividing plate 3 are formed toward the upstream side of the rotation accompanied by the downward movement of the screw blades 5 as shown in the embodiment, the processing tank Screw blade 5 at the top of 1
The downward pushing force due to the rotation of the processing medium 2 acts on the treatment medium 2 to promote the depression of the treatment medium 2 to the lower part, and as a result, the operating time of the stirring means when the treatment medium 2 is replaced can be reduced.

[0038]

As described above in detail, in the apparatus of the present invention, the dividing plate is installed inside the processing tank for containing the processing medium, and is divided into the upper portion including the rotation range of the stirring blade and the lower portion including the discharge port. At the same time, since the communication hole is formed in the dividing plate with an opening directed to the upstream side with respect to the rotation of the stirring blade in the downward direction, the normal processing is performed by the rotation of the stirring blade in the upward direction. By stirring the medium and taking in the garbage thrown into the treatment tank into the treatment medium, the kitchen waste is decomposed at the top of the treatment tank, while the stirring blade is replaced when the treatment medium needs to be replaced. By rotating in the opposite direction, the processing medium can be dropped to the lower part of the processing tank through the communication hole and taken out from the outlet opening to the lower part, and the replacement of the processing medium can be performed easily and hygienically. Always throughput Etc. it is possible to use in a superior state, the present invention exhibits an excellent effect.
