One or a plurality of cutter members 9 are fixed substantially in the radial direction on the upper side, and the lower rotary vane 8 is configured to rotate on the upper side of the cutter member 9 at a slight interval.

The whole of the garbage disposal according to the present invention is as described above. Next, the details of each part will be described.
2 is a horizontal sectional view taken along the line AA in FIG.
For example, three strip-shaped iron plates 9 are radially welded and fixed to the bottom plate 3 of the processing chamber.

The iron plate 9 functions as a cutter member, but it does not necessarily have to be radial, and is angled by an angle α with respect to the radial direction, so that when the lower rotary blade 8 passes, the scissors are used. Since the passage position is gradually moved so that the blade edge of is closed, the load on the motor when cutting fibrous food waste is reduced. The cutter member 9 may also be inclined like the lower rotary blade 8 described above.

FIG. 3 is a horizontal sectional view taken along the line BB in FIG. 1, in which the lower rotary vane 8 is arranged on the cutter member 9 with a slight interval, and the lower rotary blade 8 is attached to the rotary shaft 7. Radially attached and fixed. In addition, the lower rotary blade 8 is 1
Two sheets are provided at intervals of 80 degrees, but three or more sheets may be provided at a constant angular interval.

FIG. 4 is a horizontal sectional view taken along the line CC in FIG. 1, in which the overflow cylinder 4 is arranged on the lower rotary vane 8 at a slight interval, and the upper end of the overflow cylinder 4 is formed as described above. Thus, it is fixed to the side wall 1 of the processing chamber through the horizontal supporting member 5. In the illustrated example, three horizontal support members 5 are provided radially, and one of them is extended to the inside of the overflow cylinder 4.

The overflow cylinder 4 has a radius R larger than its height H, as shown in FIG. Further, the lower end of the overflow cylinder 4 has a triangular wave shape such as a saw tooth shape.

FIG. 5 is a horizontal sectional view taken along the line D--D in FIG. 1, in which the upper rotary vanes 6 are arranged at a slight interval on the horizontal support member 5 to perform the above-mentioned rotation. Axis 7
It is attached and fixed radially. This upper rotary blade 6
Have the same number as the lower rotary vane 8, and also the lower rotary vane 8
On the other hand, the upper rotary blade 6 is arranged so as to be displaced in the circumferential direction.

As shown in FIG. 1, the upper rotary blade 6 has its upper surface inclined forward and downward, and the lower rotary blade 8 also inclined forward and downward, as shown in FIG. As shown in FIG. 1, the lower rotary blade 8 and the upper rotary blade 6 have a strong member such as an angle 10 welded and fixed to the back surface thereof, and the angle 10 is radially attached to the rotary shaft 7. It is preferable to fix it to.

FIG. 6 is a cross-sectional view for explaining the stirring and mixing operation of the raw dust in this raw dust processing apparatus. In the garbage processing device of the present invention, a bacterium that decomposes garbage is mixed with garbage,
Moreover, the processing chamber 2 is moved to a position higher than the overflow cylinder 4.
Put it in. Therefore, the overflow cylinder 4 is not made too high so that a small amount of garbage can be treated.
As shown in FIG. 1, a structure having a height H smaller than the radius R may be used.

When the rotary shaft 7 is rotated by the motor, the lower rotary vane 8 and the upper rotary vane 6 are rotationally driven, and when the lower rotary vane 8 passes through the garbage 11 by rotation, as shown in FIG.
As shown in FIG. 5, the lower rotary vane 8 pushes up the raw dust 11 and raises it like 11a. As a result, the raw dust at the raised portion 11a overflows from the outside of the overflow cylinder 4 and falls.

By repeating this operation, as shown by the arrow in FIG. 6, the raw dust falls from above the overflow cylinder 4 to the inside, passes under the overflow cylinder 4 from the inside to the outside, and rises outside. While circulating in this way, the garbage and the degrading bacteria are stirred and mixed to decompose the garbage. Therefore, it is possible to stir and mix by circulating the garbage without using a screw or the like unlike the conventional case. It should be noted that the raw garbage 1 is located sufficiently above the upper rotary blade 6.
Even if 1 is added, the flow in the direction of the arrow is performed smoothly, so there is no hindrance to the disassembly process.

The rotation of the upper rotary blade 6 also acts to move the raw dust from the outside to the inside of the overflow tube 4. Therefore, when the upper rotary blade 6 is angled by the angle β with respect to the radial direction, as shown by the chain line in FIG. 4, the raw dust can be moved into the overflow tube 4 more smoothly. Further, it is more effective if it is curved like a broken line.

In order for the upper rotary blade 6 to pass over the horizontal support member 5 to cut the fibrous garbage, the upper rotary blade 6 has the same reason as the angle α in FIG. It is better to make an angle β.

FIG. 10 is a left side view. On the upper side of the front side of the cylindrical main body 1, there is a lid 12 for the garbage input port, and on the lower side of the front side, there is an outlet 13 for the decomposed fertilizer.

Further, similarly to the previously proposed garbage disposal, a motor for rotating the rotating shaft 7 is mounted on the ceiling plate covered on the main body 1 and is covered with a cover 14. . Further, a deodorizer 15 is installed that sucks air in the processing chamber 2 and passes it through water to collect dust and eliminate a bad odor.
