[0002]

2. Description of the Related Art As a waste disposal apparatus of this kind, the present applicant has disclosed a "garbage disposal apparatus" disclosed in Japanese Patent Application No. 4-98213.
Has already provided. As shown in FIG. 9, this food waste processing device is provided with a container 1 into which food waste as raw material (waste) is put, an agitating carrier 2 provided in the container 1, and the container 1. With a raw material charging port 3 and the agitating and conveying machine 2 provided at the center of the container 1 in the vertical direction.
A stirring means 5 rotatable about the central axis 4 for scraping garbage located on the front side (arrow (a) side) and dropping it toward the rear side (arrow (b) side); Means 5
Is provided on the rear side of the agitator 5 and is pressed by the garbage scraped up by the agitating means 5. It is composed of a driving means 7 for driving. Further, a raw material input port 3 is provided on a side portion of the above-mentioned raw waste processing device, and raw food waste can be input into the container 1 through the raw material input port 3.

In the garbage processing apparatus configured as described above, the garbage on the front side (arrow (a) side) is removed by the stirring means 5 of the stirring and conveying machine 2 as shown by the arrow (c). The pressure receiving plate 6 is scraped and dropped to the rear side (arrow (b) side) of the pressure receiving plate 6, whereby the pressure receiving plate 6 is pressed by the garbage accumulated on the rear side of the pressure receiving plate 6, and the stirring and transporting machine 2 moves forward (pressure receiving). (The side opposite to the side where the plate 6 is located). By mixing and stirring the garbage with the stirring and transporting machine 2 while running the stirring and transporting machine 2 in this manner, the garbage is fermented and decomposed by the bacteria put in advance. Has become.

[0004]

In the garbage processing apparatus constructed as described above, the garbage in front of the garbage is scraped up by the agitating means 5 of the agitating / transporting machine 2 and the rear side of the pressure receiving plate 6 in the rear. The garbage that has just been thrown in from the material inlet 3 is also scraped up and deposited on the rear side of the pressure receiving plate 6. That is, in the above-mentioned garbage disposal apparatus, all the large-sized garbage that has just been introduced from the raw material input port 3 can be scraped up, so that the large-sized garbage is first introduced and deposited. There is a problem that it is not easily mixed into the garbage and it takes a long time to mix into the garbage. As a result, there is a problem that fermentation does not proceed smoothly, and there is room for improvement in this respect.

The present invention has been made in view of the above circumstances, in which raw garbage (waste) having a large grain, which has just been charged from the raw material charging port, is smoothly stirred into the raw material charged previously. It is an object of the present invention to provide a waste treatment device capable of efficiently performing stirring fermentation of the raw material.

[0006]

In order to achieve the above object, the first invention is to crush raw materials such as raw garbage, and then
With a waste treatment device that processes by stirring and fermenting

The container is arranged vertically in the center of the container so that the center axis of the container is the same as that of the container , the raw material charging port is on the upper side, and the raw material charged from the raw material charging port is on the lower side at the bottom of the container. central material discharge port for discharging comprises: a material feed portion respectively formed at the raw material supply portion, a central axis of the container
And a crushing blade that is provided to rotate as a crusher for crushing the raw material charged from the raw material charging port , and a bottom in the container.
Centered around the central axis of the container
A centrifugal blade that is provided so as to rotate and moves the raw material crushed by the crushing blade toward the inner wall side of the container, and a bottom portion inside the container and around the raw material supply portion.
, So that it turns around the center axis of the container.
Provided, by the centrifugal blade, a stirring blade for scooping up and lifting upward the raw material moved toward the inner wall side of the container, and the periphery of the raw material supply section in the container,
And, above the stirring blade, the central axis of the container
And a stirring and raising blade that is provided so as to swirl around and that raises the raw material scooped by the stirring blade while stirring.

In the second invention, the stirring blade of the first invention is constituted by a screw.
