Abstract

PROBLEM TO BE SOLVED: To provide a garbage treating machine by which the garbage charged into a fermentation tank is agitated and crushed by a agitating tine shaft provided horizontally in the tank and fermented for decomposition. SOLUTION: The inside of a fermentation tank is divided by a first partition and a second partition 11 into a feed compartment A1, a treating compartment A2 and a discharge compartment A3. The treated material overflow of the second partition 11 is set lower than that of the first partition to reduce the retention and residence time of the finely granulated material in the treating compartment and to reduce the rotation load on an agitating tine shaft B. Besides, the upper side 11U of the second partition 11 is made almost flush with the center O of the shaft to let the treated material overflow the upper side into the discharge compartment A3 from the treating compartment A2, and the height of the upper side of the second partition 11 is made variable to adjust the retention and residence time of the finely granulated material in the treating compartment A2. Further, at least one of the pawls is arranged in the treating compartment to reinforce the transfer of the treated material from the treating compartment to the discharge compartment by the agitating and transferring action of the pawl.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fermentation treatment tank of a garbage disposer for fermenting and decomposing organic matter such as garbage, and more specifically, to a fermentation treatment tank having a charging chamber. The present invention relates to a configuration of a partition wall that divides into a processing chamber and a discharge chamber, and an arrangement configuration of a stirring claw related thereto.

[0002]

2. Description of the Related Art A garbage disposer is known which composts organic matter such as garbage generated in general households and kitchens of restaurants by utilizing decomposition by fermentation bacteria, and uses the compost as a fertilizer for reduction. And the general ones of this kind
The garbage and fermentation bacteria put into the fermentation tank are stirred at any time with a stirring claw mounted on a rotating claw shaft supported horizontally in the tank to promote fermentation and decomposition of garbage and composted. Is taken out of the tank.

[0003]

In the above-mentioned garbage disposal machine, if the inside of the fermentation treatment tank is a single chamber, the garbage mixed with the garbage that has undergone the fermentation treatment is mixed in the entire area of the single chamber. Since it is difficult to separate the two, the efficiency of the treatment is poor and the accuracy of the finished product as compost is not good.

[0004] Therefore, the inside of the fermentation treatment tank is partitioned into a plurality of chambers of an input chamber, a processing chamber, and a discharge chamber by a partition wall in a direction perpendicular to the axis of a stirring claw shaft provided horizontally in the tank, and a new production chamber is formed. The garbage is thrown into the input chamber, and the garbage is stirred and pulverized in the input chamber, and the decomposed substance by the fermentation bacteria is advanced to a certain extent. It is preferable that the overflowed finished product is sent out of the tank through the discharge port provided in the discharge chamber and collected.However, when the inside of the fermentation treatment tank is partitioned by a partition wall, it is agitated and pulverized to obtain fine particles. Movement is interrupted by the partition wall, and particularly, accumulation and stagnation occurs at the lower bottom of the processing chamber and the discharge chamber, and the stagnation causes an excessive rotation load on the stirring claw shaft. Situation that would lock the .

According to the present invention, the inside of a fermentation treatment tank is partitioned into a charging chamber, a processing chamber, and a discharge chamber by a partition wall, thereby efficiently and satisfactorily separating raw garbage and fermented food. Despite the fact that the material that has been agitated and pulverized into fine particles does not excessively stagnate and accumulate on the lower bottom of the processing chamber or discharge chamber, the rotational load on the agitating claw shaft is reduced, and the fermentation and decomposition of garbage In addition, a series of processes for discharging the finished product from the tank are smoothly and smoothly performed.

[0006]

That is, the present invention relates to a fermentation treatment tank comprising a first partition wall and a second partition wall in a direction perpendicular to the axis of a stirring claw shaft provided laterally in the tank. Partitioning into the input chamber, processing chamber, and discharge chamber by the partition wall, raw garbage is input into the input chamber, and the fermentation decomposition process is performed while stirring, and the processed material is transferred from the input chamber to the processing chamber and from the processing chamber to the discharge chamber. In the garbage disposer configured to cause the overflow of the processing waste, the height of the processed material overflowing of the second partition wall separating the processing chamber and the discharge chamber is set to the height of the first partition wall separating the processing chamber and the input chamber. The height of the processed material is set lower than the overflow height of the processed material, and the upper side of the second partition wall is positioned at substantially the same height as the axis of the stirring claw shaft, and the processed material overflows from the processing chamber to the discharge chamber. Is performed over the upper side, whereby the agitated and pulverized granulated material is processed. So that there is no undue stagnant deposited into the room.

[0007] Further, by configuring the second partition wall, which is lower than the first partition wall, to be able to change and adjust the height, when the crushed material is fine according to the fineness of the crushed material in the processing chamber, By lowering the second partition wall, the overflow from the processing chamber is accelerated. If the pulverized material is rough, the second partition wall is raised to extend the residence time, and the appropriate pulverization state is obtained by dry pulverization in the same chamber. I am getting it.

In addition, a plurality of agitating claws provided on the agitating claw shaft are disposed in the input chamber and the interior of the processing chamber, and are discharged from the processing chamber by the agitating transfer action of the agitating claw disposed in the chamber of the processing chamber. By helping the material overflow into the room,
The overflow of the granulated material from the processing chamber to the discharge chamber is performed more efficiently.
