Abstract

PROBLEM TO BE SOLVED: To efficiently treat garbage automatically by installing a drying chamber for receiving garbage and a device for supplying the garbage in the drying chamber to a fermentation chamber in a garbage treatment machine equipped with an inlet in the upper part and the fermentation chamber in the lower part. SOLUTION: In the treatment of garbage, first a lid 14 is opened, and garbage is fed from an inlet 12 into a drying chamber 16. Next, an air heater 50 and fans 52, 56 are actuated, and the garbage is dried so that the water content, which is usually about 80%, is reduced to about 60%. When the weight of the garbage fed is detected to be reduced by half by drying, a motor 32 is operated to rotate a plate in a vertical posture. In this way, the garbage in the drying chamber 16 is supplied to a fermentation chamber 34 and is agitated by an agitation blade 36 to be mixed with a microorganism culture base material 35. The fermentation chamber 34 is heated by a panel heater 46, and the garbage is decomposed actively by microorganisms.

Description

Detailed Description of the Invention

[0001]

The present invention relates to a garbage disposal machine for decomposing garbage with microorganisms.

[0002]

2. Description of the Related Art It has been found that when garbage is treated by a garbage disposer, a temperature of about 60 ° C. and a garbage moisture of about 50 to 60% are most suitable.

However, the water content of raw garbage is 70% (wt%).
The same applies hereinafter. ) Or more (usually about 80%), when garbage is put into the garbage disposal machine every day, the water content in the garbage disposal machine becomes excessive, and the ability to decompose microorganisms is extremely reduced. Therefore, it is performed to exhaust the excess water to the outside of the machine by exhausting it from the inside of the garbage processing machine, but due to this, the temperature inside the machine is removed and the temperature of the machine is lowered, which reduces the activity of microorganisms. is there.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a garbage treatment machine which can control the water content in the fermentation chamber to be optimum for the decomposition of garbage by microorganisms while maintaining the temperature around 60 ° C. And

[0005]

The raw garbage treating machine of the present invention is a raw garbage treating machine having an input port in the upper part and a fermentation chamber in the lower part, and a drying chamber for receiving the organic waste from the input port. In addition to the provision, a supply device for supplying raw garbage in the drying chamber to the fermentation chamber is also provided.

According to such a garbage disposal, since the garbage is dried to some extent in the drying chamber and then fed to the fermentation chamber, it is possible to prevent the moisture in the fermentation chamber from becoming excessively excessive. Also, because of this, the amount of excess water that must be discharged from the fermentation chamber is small, so heat is prevented by suppressing the flow rate of the exhaust fan that discharges the moisture out of the room, and the temperature inside the fermentation chamber can easily reach around 60 ° C. Can be maintained at

According to the present invention, a sensor for detecting the weight of raw garbage in the drying chamber is provided, and when the weight reduction rate detected by the sensor reaches a predetermined value, the supply device is operated to remove the raw garbage. It is preferable to provide a controller for feeding from the drying chamber to the fermentation chamber.

In this way, when the garbage in the drying chamber is dried to the target water content, the garbage is automatically supplied from the drying chamber to the fermentation chamber.

FIG. 1 is a longitudinal sectional view of a garbage disposer according to an embodiment. An inlet 12 is provided at the upper part of the casing 10.
Is provided, and an openable / closable lid 14 is provided. A drying chamber 16 is provided directly below the charging port 12. The bottom surface of the drying chamber 16 is partitioned by a plate 18 that can be rotated 90 °. The plate 18 is horizontally arranged by rotating shafts 20 and 22 provided at both ends thereof are supported by bearings 24 and 26. The bearing 24 is configured to detect the load applied by the weight sensors 28 and 30.

A motor 32 connected to the rotary shaft 20
Thus, the plate 18 is rotated so as to be able to take the horizontal posture shown in the drawing and the vertical posture rotated by 90 degrees therefrom.

A fermentation chamber 34 is provided below the plate 18. A stirring blade 36 is provided in the fermentation chamber 34. The stirring blade 36 includes a pulley 38, a belt 4
It is rotated by a motor 44 via the pulley 42 and the pulley 42. A panel heater 46 is provided on the inner surface of the fermentation chamber 34. Further, the fermenter 34 is filled with a microorganism culture base material 35.

An air heater 5 is provided above the drying chamber 16.
An air supply port 54 having a fan 52 and an air supply port 54 having a fan 56 is provided.
An exhaust port 62 having an exhaust fan 60 is provided in an upper part of the fermentation chamber 34.

The detection signals of the weight sensors 28 and 30 are input to the controller 64, and the motor 32 is driven by the control signal from the controller 64.

In the garbage disposal having the above structure, the lid 14 is opened and the garbage is introduced into the drying chamber 16 through the inlet 12. Then, the air heater 50 and the fan 52,
By operating 56, the garbage put into the drying chamber 16 is dried. The water content of the garbage is usually about 80%, and drying is performed until the water content becomes about 60%. In this case, the water content of the raw garbage is reduced from 80% to 60% by performing drying until the weight of the input garbage is reduced to half.

The detection signals of the weight sensors 28 and 30 are input to the controller 64, and when the weight of the input garbage is dried by half, the motor 32 is driven to bring the plate 18 into the vertical posture. Rotate. As a result, the drying room 1
Raw garbage in 6 is supplied to the fermentation chamber 34. This fermentation room 3
In 4, the food waste is agitated by the agitating blade 36 and mixed with the microorganism culture substrate 35 such as sawdust. The fermentation chamber is heated by a panel heater 46, and the garbage is actively decomposed by microorganisms to generate fermentation heat, and the temperature of the fermentation chamber rises to about 60 ° C. Insulated material 4
It is kept warm by 7 and kept without radiating heat. A small amount of excess water generated in the fermentation chamber due to the decomposition of raw garbage becomes steam due to the temperature of the fermentation chamber maintained at a high temperature, moves to the upper part of the fermentation chamber, and is discharged outside by a low-flow exhaust fan that does not affect the indoor temperature. Is discharged. According to this garbage processor, the temperature inside the fermentation chamber 34 is maintained at around 60 ° C,
The water content can be maintained at about 50 to 60%, and the decomposition treatment can be carried out under the conditions most suitable for the decomposition of garbage by microorganisms.

According to the present embodiment, when the raw garbage in the drying chamber 16 is dried to a predetermined water content, the raw garbage is automatically supplied into the fermentation chamber 34, so that the garbage treatment is automatically performed. It can be done efficiently.

As described above, according to the present invention, the temperature and moisture in the fermentation chamber can be easily maintained at the most suitable conditions for the decomposition of microorganisms. Further, according to the present invention, when the raw garbage in the drying chamber is dried to the target water content, it can be automatically supplied to the fermentation chamber, and the raw garbage processing can be automatically performed efficiently.
