5) and a combustion type deodorizer (16) that burns the odor generated from dust to deodorize.

A large number of small holes are formed in the peripheral wall of the granulation chamber (4), and a pair of perforated drums (17) (17) rotatably driven by appropriate rotation driving means are brought into contact with the granulation chamber (4). A granulator (18) which is arranged facing each other and has a scraping plate (not shown) in contact with the inner wall surface of each porous drum (17) (17).
Is provided.

Next, the operation of the dust-reducing device of the present invention will be described based on the above configuration.

First, the crushing chamber (2) of the waste treatment container (1)
When a garbage bag containing garbage such as raw garbage and plastic is put into the inside, the conveyor belt (5) at the same time as scraping the garbage bag by the chain conveyor (5) (5) with hooking claws of the bag breaking machine (6) The trash bag is ruptured due to the difference in transfer speed of (5) to discharge the trash from the trash bag to the crusher (8), and the crusher drums (7) and (7) of the crusher (8) The trash bag and the garbage, plastic, etc. discharged from the trash bag are finely crushed.

Next, the dust finely crushed in the crushing chamber (2) is collected and stored in the volume-reducing chamber (3) for fermentation treatment.
In this fermentation treatment, fermenting bacteria are added to the crushed dust, and this is stirred for about 24 hours by stirring with a stirrer (11) and contacting with air. The fermenting bacterium used for this fermentation treatment is a thermophilic aerobic bacterium that grows and activates at a high temperature (for example, 50 to 60 ° C). It is carried out by heating to 60 ° C. However, since the fermenting bacteria generate heat by themselves when fermenting, the supply of warm air by the warm air blower (15) is stopped to maintain an appropriate temperature. Further, the odor generated by the fermentation process is burned and deodorized by the combustion type deodorizer (16). And
A part of raw garbage components of fermented waste becomes carbon dioxide gas and water, and the volume is reduced and the amount of plastic remains only in powder form. Appropriate.

Next, the powdery dust reduced in volume reduction chamber (3) is granulated in the granulation chamber (4) by the screw conveyor (14).
And is granulated into pellets by the granulator (18) in the granulation chamber (4). The granulator (18) has a perforated drum (1
7) The rotary drive of (17) pushes powdery dust through the small holes through the inner wall surface of each porous drum (17) (17) through a small hole, and scrapes it with a scraping plate that is in contact with the inner wall surface. It is pelletized by dropping. After that, the granulated pellets are discharged by an appropriate discharging means and carried out to a destination as fuel or the like. In addition, when transferring the powdery dust reduced in the volume reduction chamber (3) to the granulation chamber (4) by the screw conveyor (14), the fermented dust in the volume reduction chamber (3) is about 3 minutes. If about 1 is left, the number of times of addition of fermenting bacteria can be significantly reduced in the subsequent fermentation treatment.

FIG. 2 is a schematic constitutional view showing another embodiment of the dust volume reducing apparatus of the present invention. The same components as those in the embodiment shown in FIG.

In this embodiment, a garbage storage box (19) for storing raw garbage, plastics, steel cans, aluminum cans, etc. is arranged near the garbage disposal container (1) and is accommodated in this garbage input box (19). Raw garbage, plastic, steel cans, aluminum cans, etc. are separated and removed by the can sorting conveyor (20) into the crushing chamber (2) of the waste treatment container (1), and this crushing chamber ( After finely crushing with the crusher (8) in 3), it is dried with the dryer (21) to the water content preferred by the fermenting bacteria, collected and stored in the volume reduction chamber (3), and stored in the volume reduction chamber (3). Stir with a stirrer (11) and ferment for about 24 hours to reduce the volume, transfer it to the granulation chamber (4) by the screw conveyor (14), and pelletize it by the granulator (18). After granulating, it is discharged by an appropriate discharging means and used To carry-out.

Although the above embodiment describes the case of stationary, the present invention can be mounted on a vehicle.

[0020]

As described above, according to the present invention,
It is possible to significantly reduce the volume of raw garbage, plastic waste, and other waste discharged from each household by fermenting them using biotechnology, and at the same time, reuse them as fuel, fertilizer and the like.
