[0022] A driving mechanism is provided in the rotating chamber 13, and the driving mechanism is used to drive the rotating sleeve 9 to rotate; the driving mechanism includes a motor 14, a driving wheel 15, and a driven wheel 16; the circumferential inner wall of the driven wheel 16 is fixedly connected to the circumferential outer wall of the rotating sleeve 9, the driving wheel 15 and the driven wheel 16 are meshed, the motor 14 is embedded in the top of the rotating chamber 13, and the output end of the motor 14 is fixedly connected to the driving wheel 15 through a rotating shaft

[0023] The lifting device 11 is an electric telescopic rod, a pneumatic telescopic rod or a hydraulic telescopic rod.

[0024] In this embodiment, the fan 2 is started, and suction is generated in the air inlet 4 on the filter housing 1, which easily draws the exhaust gas into the filter housing 1. When the exhaust gas flows out from the air outlet 5, it passes through the filter cartridge 7, which can filter the smoke and impurities in the exhaust gas. The filtered exhaust gas is then transported to the treatment housing 3 through the fan 2 for further treatment.

[0025] The filtering mechanism performs a pre-filtering function on impurities and smoke in the exhaust gas; when cleaning the filtering mechanism, by starting the lifting device 11, the dust removal mechanism moves downward, and starting the motor 14, the driving wheel 15 and the driven wheel 16 are engaged, so that the driven wheel 16 can rotate. When the driven wheel 16 rotates, it synchronously drives the rotating sleeve 9 to rotate, so that the cleaning brush 10 on the inside of the rotating sleeve 9 can clean the impurities and smoke filtered on the outer surface of the filter cartridge 7, thereby improving the cleaning effect of the filter cartridge 7 and ensuring the quality of the filter cartridge 7 for exhaust gas filtration.

[0026] As a technical optimization solution of the present invention, a ring-shaped limit sleeve 17 is provided on the top of the rotating sleeve 9, and a limit groove 18 adapted to the limit sleeve 17 is opened on the top of the inner part of the annular slide groove 12. The limit sleeve 17 is located in the limit groove 18, and the limit sleeve 17 can rotate in the limit groove 18.

[0027] In this embodiment, when the rotating sleeve 9 rotates, the limiting sleeve 17 on the rotating sleeve 9 is limited by the limiting groove 18, which can improve the rotation stability of the rotating sleeve 9.

[0028] As a technical optimization solution of the present invention, an activated carbon layer 19 and a nozzle 20 are provided inside the processing shell 3. The nozzle 20 is located above the activated carbon layer 19. The air inlet 4 and the air outlet 5 on the processing shell 3 are respectively located below and above the activated carbon layer 19. A water supply pipe 21 connected to the nozzle 20 is provided on the processing shell 3; a pump 22 is provided on the processing shell 3, and the input and output ends of the pump 22 are connected to the bottom of the processing shell 3 and the nozzle 20 through a pipeline; a filter cover 23 connected to the pipe head of the input end of the pump 22 is provided in the processing shell 3.

[0029] In this embodiment: the air outlet 5 on the processing shell 3 is located below the water level, and the exhaust gas filtered inside enters the processing shell 3. When the exhaust gas moves upward from below the water level, small impurities in the exhaust gas can be retained in the water and will not be discharged from the processing shell 3 together with the exhaust gas; and when the exhaust gas flows out from the air outlet 5, it will pass through the activated carbon layer 19. The activated carbon layer 19 can not only efficiently adsorb and remove organic pollutants in the exhaust gas again, but also improve the odor of the exhaust gas (activated carbon is a porous carbon-containing substance. When the exhaust gas passes through the activated carbon layer 19, these pollutants are captured by the micropores on the surface of the activated carbon and fixed inside the pores, thereby achieving the purpose of purifying the exhaust gas and improving the odor). The water supply pipe 21 is opened, and the nozzle is used to spray the activated carbon layer 19, which helps to protect the activated carbon layer 19 from being blocked by particulate matter, prevent the activated carbon from being saturated, improve the purification efficiency, and improve the filtration quality of the activated carbon layer 19.

[0030] When there is water inside the treatment shell 3, the water supply pipe 21 can be closed, the pump 22 can be started, and the filter cover 23 can filter the water inside the treatment shell 3, which can be recycled to reduce the waste of water resources;

[0031] The position of the fan 2 is higher than the water level inside the processing shell 3.

[0032] As a technical optimization solution of the present invention, the bottoms of the filter shell 1 and the treatment shell 3 are both conical structures with a larger top and a smaller bottom. The bottoms of the filter shell 1 and the treatment shell 3 are both provided with a drain pipe 24, and a valve 25 is provided on the drain pipe 24.

[0033] In this embodiment, the valve 25 on the bottom pipe 24 of the filter housing 1 is opened to facilitate cleaning of soot and impurities at the bottom of the filter housing 1 ; the valve 25 on the bottom pipe 24 of the treatment housing 3 is opened to facilitate cleaning of sewage at the bottom of the treatment housing 3 .

[0034] Working principle: First, start the fan 2, and suction is generated in the air inlet 4 on the filter housing 1, which makes it easy to draw the exhaust gas into the filter housing 1. When the exhaust gas flows out from the air outlet 5, it passes through the filter cartridge 7, which can filter the smoke and impurities in the exhaust gas. The filtered exhaust gas is transported to the treatment housing 3 through the fan 2. The activated carbon layer 19 in the treatment housing 3 performs a secondary filtration on the exhaust gas, and finally it is discharged safely.

[0035] The filtering mechanism performs a pre-filtering function on impurities and smoke in the exhaust gas; when cleaning the filtering mechanism, by starting the lifting device 11, the dust removal mechanism moves downward, and starting the motor 14, the driving wheel 15 and the driven wheel 16 are engaged, so that the driven wheel 16 can rotate. When the driven wheel 16 rotates, it synchronously drives the rotating sleeve 9 to rotate, so that the cleaning brush 10 on the inside of the rotating sleeve 9 can clean the impurities and smoke filtered on the outer surface of the filter cartridge 7, thereby improving the cleaning effect of the filter cartridge 7 and ensuring the quality of the filter cartridge 7 for exhaust gas filtration.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
