The operation of processing the garbage by the garbage processing apparatus 10 having the above configuration will be described. First, the lid 1
4 is opened, a predetermined amount of the bacterial bed is put into the hopper 22, and the motor 24 is energized to rotate the shaft 27 and supply the bacterial bed into the processing tank drum 30. Then, the temperature inside the processing tank drum 30 is brought close to a predetermined temperature (a temperature at which the aerobic fermentation bacteria in the bacterial bed can be actively activated) by a heater (not shown). However, since the fermentation heat of the aerobic fermenter keeps the inside of the treatment tank drum 30 at an appropriate temperature from spring to autumn, it is basically unnecessary to use a heater except during severe winter.

Next, garbage and an appropriate amount of a pH adjuster are charged into the hopper 22, and the motor 24 (shaft 27) is rotated at a predetermined rotation speed. Thereby, the hopper 22
The garbage introduced into the inside is continuously and quantitatively introduced into the processing tank drum 30. Simultaneously with the input of the garbage, the motor 62 (the processing tank drum 30) is rotated at a predetermined rotation speed and frequency, and the bacteria bed in the processing tank drum 30 and the garbage are stirred. The rotation speed of the processing tank drum 30 (motor 62) is about 1 to 2 rpm, and the rotation frequency after the inputted garbage and the bacterial bed are uniformly stirred is once an hour. About 5 minutes each time. Further, water is supplied from a water supply source (water supply pump), not shown, into the water sprinkling pipe 72 via the shaft 27 and the hose 74, and the water is supplied from the water sprinkling port 76 of the water sprinkling pipe 72 to the treatment tank drum 3
Water is sprinkled in 0. In addition, it is preferable that the upper surface of the bacteria bed and the garbage to be charged into the processing tank drum 30 is about half the height of the processing tank drum 30 from the viewpoint of stirring efficiency and the like. In addition, p charged into the processing tank drum 30
The amount of the H adjuster may be such that the whole of the contents in the processing tank drum 30 which is easily acidified with the decomposition can be made neutral.

In this embodiment, the bacteria bed and the garbage are agitated by rotating the processing tank drum 30 periodically,
Since a sufficient amount of air is sent into the bacterial bed and the bacterial bed and the garbage are uniformly mixed, the decomposition of the garbage is promoted. Therefore, the garbage introduced into the processing tank drum 30 is decomposed and liquefied in a short time. The liquefied matter generated by this decomposition treatment is supplied from the liquid permeable plate 34 to the processing tank drum 3 together with the water sprinkled in the processing tank drum 30.
The liquid is dropped outside and stored in the storage liquid tank 40. The liquefied matter stored in the storage liquid tank 40 is discharged out of the garbage disposal device 10 through the drain pipe 18. Since the aerobic fermentation bacteria are also contained in the liquefied matter stored in the storage liquid tank 40, even if the organic matter being decomposed leaks from the liquid-permeable plate 34 and falls into the storage liquid tank 40, the aeration pipe is used. It is decomposed and purified by aeration. Also, this liquefied material is B
Since it contains OD, COD and SS components, it can be used as liquid fertilizer.

As is apparent from the above description, in the garbage processing apparatus 10 of the present embodiment, the feeder 20 supplies the garbage regardless of the rotation of the processing tank drum 30 (there is no need to synchronize with the rotation of the processing tank drum 30). Since the garbage can be charged into the processing tank drum 30, the garbage can be continuously input while the processing tank drum 30 is operating. Further, since the garbage can be continuously supplied by the supply device 20, a large amount of garbage is not supplied at one time, the bias of the supplied garbage can be prevented, and the decomposition processing can be performed efficiently. Becomes possible. In the garbage disposal apparatus 10 described above, the sprinkler pipe 72 is fixed to the supply pipe 25 of the supply apparatus 20, and the water is supplied to the sprinkler pipe 72 by the shaft 27 and the hose 74. Even if the drum 30 rotates, the sprinkler tube 72 and the hose 74 do not rotate, and the handling thereof becomes easy. Furthermore, the above-mentioned garbage processing apparatus 10
Then, the processing tank drum 30 is provided in a substantially horizontal shape,
Since the motor 62 is provided in the lower space of 0, the garbage disposal device 10 can be made compact.

However, the present invention is not limited to the above-described embodiment, and the present invention can be variously modified based on the knowledge of those skilled in the art. , Can be implemented in an improved form. For example, in the above-described embodiment, the processing tank drum 3 is passed through the shaft 27 of the supply device 20 from an external water supply source.
Although the water was supplied to the sprinkling pipe 72 inside 0, it is not limited to such an example, and for example, a method as shown in FIG. 6 can be adopted. Here, FIG. 6 is an enlarged view showing a portion of the opening 36 of the garbage disposal apparatus according to another embodiment. As shown in FIG. 6, in this example, a flange 80 is fixed to the supply pipe 25, and a hose mounting port 81 is provided in the flange 80. One end of a hose 74 connected to an external water supply source and connected to the sprinkler tube 72 is connected to the outside of the hose mounting port 81. Even with such a structure, the flange 80 is fixed to the supply pipe 25 and the position of the hose mounting port 81 does not change depending on the rotation of the processing tank drum 30. In the example shown in FIG. 6, the periphery of the hose mounting port 81 is
And the sprocket mounting bracket 65,
The path through which bacteria beds, garbage and the like stored in the processing tank drum 30 leak out is bent to seal between the supply pipe 25 and the drum processing tank end face 31. Also in this case, since the drum-side plate 82, the flange 80, and the sprocket mounting bracket 65 are not in contact with each other, these members are not worn and the sealing effect is not reduced.

Further, in the above-described embodiment, the processing tank drum 30 is provided in the main casing 12 in a substantially horizontal shape. However, the present invention is not limited to such an example. May be provided at an angle. According to such a configuration, the garbage and the like introduced from the supply pipe 25 move to the end opposite to the opening 36 due to gravity, so that the bacteria bed and the garbage in the processing tank drum 30 can be efficiently stirred. It can be carried out.

In the above-described embodiment, the motor 62 serving as a drive source for rotating the processing tank drum 30 and the supply device 2
Although two motors 24 are used as the zero driving source, they may be used as one power source (motor). For example, a gear or the like that meshes with the chain 68 rotated by the motor 62 may be provided, and the supply device 20 may be driven by the rotation transmitted to the gear. In this case, the ratio of the rotation of the shaft 27 to the rotation of the processing tank drum 30 can be easily adjusted by adjusting the gear ratio of the gear described above.

Further, in the above-described embodiment, a water spray pipe for spraying water toward the liquid-permeable plate 34 may be provided at a position above the processing tank drum 30 so as to face the liquid-permeable plate 34. good. Thereby, the outer surface of the liquid-permeable plate 34 can be cleaned,
