Detailed ways

The present invention will be further described below in conjunction with drawings and embodiments.

As shown in Fig. 1, Fig. 2, Fig. 3, the present invention comprises fermenting device, feeding device, stirring device, leachate respraying device, heating device and ventilating device; Wherein:

1) Fermentation device: two horizontal fermentation bins are arranged horizontally, connected by the sealed pipeline of the conveying device;

2) Material delivery device: one end of the screw propeller 12 stretches out from the bottom of the first fermentation bin 7, and is connected to the motor 1 through the clutch and the reducer 2, and the other end of the screw propeller 12 passes through the sealed pipeline between the two bins, and stretches out. into the second fermentation bin 10;

3) Stirring device: composed of a stirring shaft 6 and a detachable blade 5, the stirring shaft 6 is horizontally fixed in the middle of the first and second fermentation bins 7 and 10 through a bearing; connected;

4) Leachate back-spraying device: a porous stainless steel plate 17 is installed at the bottom of each bin, which is connected to the leachate recovery device 14 through a pipeline, and the pipeline of the sewage pump 9 is inserted into the leachate recovery device, and connected to each fermentation tank through a pipeline Inside;

5) Heating device: fix the stainless steel heating tube 15 on the inner wall of each fermentation bin;

6) Ventilation device: each fermentation bin is provided with a perforated pipeline, which is connected to the air pump 11 .

Each of the fermentation chambers is connected to the exhaust gas purifier 8 through pipelines respectively.

The organic waste is crushed to form particles with a diameter of less than 30 mm, and is put into the first fermentation bin 7 from the feeding port. Every once in a while, the motor 1 rotates, through the reducer 2, drives the transmission shaft 16 to rotate, the transmission shaft 16 drives the small pulley 4 to rotate, the small pulley 4 drives the large pulley 3 to rotate through the belt, and the large pulley 3 drives the stirring shaft 6 to rotate, stirring The stirring blade 5 fixed on the shaft rotates to turn the material, so that the material is in contact with the air that the pipeline of the air pump 11 feeds. After the heating tube 15 is energized, the air in the storehouse is heated. The air pump 11 blows cold air into the fermentation bin through the pipeline, which not only accelerates the drying of the garbage, but also provides the oxygen needed by the organism. By controlling the heating time and the amount of air introduced, the temperature in the fermentation chamber is kept at the optimum temperature for biological fermentation. The leachate of the rubbish passes through the porous stainless steel plate 17, flows into the leachate recovery device 14 at the bottom of the bin through the pipeline, and is sprayed back into the fermentation bin through the pipeline of the sewage pump 9.

After the primary fermentation is finished, the screw propeller 12 starts to rotate, and the garbage is pushed into the second fermentation bin 10, and the garbage is evenly piled up by the tumbling action of the stirring blade 5. At the same time, a certain amount of material is reserved in the first fermentation chamber 7 to provide high-efficiency bacteria for re-feeding the material. After the remaining materials are transported, the second fermentation bin 10 starts to work, and the principle of each device is the same as that of the first fermentation bin 7 . The gas produced by the fermentation bin enters the exhaust gas purifier 8 through the pipeline and is discharged into the atmosphere. The whole system is controlled by single chip microcomputer.

The specific embodiments above are used to explain the present invention, rather than to limit the present invention. Within the spirit of the present invention and the protection scope of the claims, any modification and change made to the present invention will fall into the protection scope of the present invention.
