Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating garbage which dries various kinds of garbage and treats them into fine powder.

[0002]

2. Description of the Related Art Conventionally, the following is known as an apparatus for treating garbage. That is, a hopper into which raw garbage is put, a dehydrating means for dehydrating the raw garbage, and a treatment tank for treating the raw garbage dehydrated by the dehydrating means into fine powder, and the dehydrating means is a cylindrical body. There is known an apparatus for treating food waste, which is provided with a screw that is rotatably supported by being disposed in the axial direction of the cylinder. Since such a conventional device is provided with the dehydrating means having the above-described configuration, the processing speed of raw garbage can be increased as compared with a device not having such dehydrating means.

[0003]

However, in the prior art,
Since the cylindrical body and the screw constituting the dewatering means are arranged in the lateral direction (horizontal direction) and the processing tank is arranged below the dewatering means, the efficiency of dewatering raw garbage is deteriorated and the dewatering means is also provided. However, there is a drawback in that the height of the entire apparatus is increased by arranging the above in the upper part of the processing tank.

[0004]

[Means for Solving the Problems] In view of such circumstances,
A hopper into which raw garbage is put, a dehydrating means for dehydrating the raw garbage, and a treatment tank for treating the raw garbage dehydrated by the dehydrating means into fine powder, and the dehydrating means is a cylindrical body, In an apparatus for treating food waste, which is provided with a screw rotatably supported by being arranged in the axial direction in the cylinder,
The screw of the dehydrating means is arranged in the vertical direction, while the hopper and the lower part of the dehydrating means are connected via a communication pipe, the upper part of the dehydrating means and a processing tank are connected via a communication pipe, and the dehydration is further performed. A drainage pipe is connected to the lower part of the means.

[0005]

According to this structure, since the cylindrical body and the screw constituting the dewatering means are arranged in the vertical direction, the dehydration of raw garbage is more efficient than the above-mentioned conventional arrangement in which they are arranged in the horizontal direction. It can be performed. Moreover, by arranging the dehydrating means in the vertical direction, the dehydrating means and the processing tank can be arranged in parallel, so that the height of the entire apparatus can be made lower than in the prior art.

To the third fermentation chamber 16-18, the function of sequentially transferring the contents stored in the third fermentation chamber 16 to 18 to the right side while stirring is performed. still,
A communication pipe 28 is installed between the first fermentation chamber 16 and the cylindrical body 8 of the dehydrating means 7, and a discharge port 29 is installed in the third fermentation chamber 18. Reference numeral 30 is a blower, 31 is an exhaust pipe provided between the blower 30 and the processing tank 14,
Reference numeral 2 denotes an exhaust pipe provided between the blower 30 and the deodorizing tank 33. Reference numeral 34 is an intake pipe, and 35 is a control panel. Next, a method for treating raw garbage using the above-mentioned apparatus will be described. The raw garbage put in from the hopper 6 is crushed by the rotary blade 3 of the crushing means 5 and is blown by centrifugal force to open the communication pipe 13. It is sent to the lower part of the cylindrical body 8 of the dehydrating means 7 from the portion 13a, and is sent to the inside of the middle cylindrical body 8a from the opening 13b. This raw garbage is compressed and dehydrated upward by the rotating screw 9 and sent from the relay chamber 8 to the first fermentation chamber 16 of the treatment tank 14 via the communication pipe 28. The water generated by compressing the garbage is
It is discharged to the outside through the drainage pipe 10 from a large number of small holes provided in the middle tubular body 8a. The garbage is gradually provided on the partition plate 15a while being heated by the heating means 19 in the first fermentation chamber 16 and subjected to the fermentation bacterium which has been charged in advance, while being stirred by the stirring rod 24 of the stirring transfer means 22. Transfer port 1
6a is transferred into the second fermentation chamber 17, where it is also heated by the heating means 20 and agitated by the stirring rod 24, and the third fermentation chamber 1 is passed through the small hole 17a provided in the partition plate 15b.
Transferred to 8. In this third fermentation chamber 18 as well, the garbage is turned into fine powder by the heating by the heating means 21 and the stirring by the stirring rod 24, and is discharged from the discharge port 29 to the outside. Meanwhile, the malodor generated inside the processing tank 14 is sent to the deodorizing tank 33 by the blower 30 to be deodorized.
The outside air is sent to the processing tank 14 via the air supply pipe 34. In the above operation, the temperature of the first fermentation chamber 16 was controlled to 60 ° C, the temperature of the second fermentation chamber 17 was controlled to 50 ° C, and the temperature of the third fermentation chamber 18 was controlled to 60 ° C. The rotation speed of each stirring rod 24 of the stirring / transferring means 22 is 6 to 7 /.
The cycle of 10 minutes forward rotation, 10 minutes rest, 10 minutes reverse rotation at rpm was repeated. When 3 days have passed in this way, the free-flowing fine powdery processed material is discharged from the discharge port 29, and at the time of input, garbage having a water content of 80% becomes fine powder having a water content of about 18%, and the initial volume It was reduced to about 1/5. It takes three days from the first charging of garbage to the discharge of the finely powdered processed material to continuously feed the garbage into the hopper 6. It was thrown in after a lapse of days, and then continuously fed every other day. After the lapse of 3 days, the free-flowing fine powdery processed material was continuously discharged and collected from the discharge port 29 smoothly.
In addition, the deodorizing tank 33 is a forest bath deodorizer N-1 manufactured by Ace Corporation used for vacuum cars.
01 was used. The finely powdered treated product discharged from the discharge port 29 could be used as an organic fertilizer or a soil improving material. According to the above-mentioned embodiment, a large amount of raw garbage can be continuously dried to be a finely powdered organic fertilizer or a soil improving material, and effective use of raw garbage and prevention of pollution such as environmental pollution. This can be effectively achieved. At that time,
When the garbage is finely crushed by the crushing means, the dehydration effect and the drying rate and the fermentation decomposition rate can be further increased. There is an extremely strong malodor generated by the garbage during fermentation decomposition in the treatment tank. However, since this malodor is almost completely removed by the deodorizing means 33, it may disturb the neighborhood during operation of the device. There is no such thing.
Furthermore, by individually controlling the temperature of each fermentation chamber or by controlling the stirring transfer speed,
It is possible to perform a rational decomposition and drying treatment according to the state of raw garbage in each fermentation chamber and the type of raw garbage, and this makes it possible to perform treatment in a shorter time. Also,
According to the above-mentioned embodiment, since the cylindrical body 8, the intermediate cylindrical body 8a and the screw 9 which constitute the dehydrating means 7 are arranged side by side on the side portion which is close to the processing tank 14, the dehydrating means 7 is disposed in the processing tank 14. As compared with the conventional device provided laterally above, the efficiency of dehydrating raw garbage can be improved and the height of the entire device can be reduced.

[0007]

As described above, according to the present invention, the garbage can be dehydrated more efficiently than in the prior art, and the height of the entire apparatus can be made lower than in the prior art. The effect is obtained.
