[0022] (1) In the present invention, the operator turns on the motor, and the motor drives the position of the rotating rod to rotate through the rotating shaft at the output end, and the rotating rod further drives the position of the bevel gear one to rotate. The side wall of the bevel gear one is meshed with the side wall of the bevel gear two. Therefore, when the bevel gear one rotates, it can drive the position of the bevel gear two to rotate.

Then, the operator turns on the suction pump, and the suction pump transports the exhaust gas after the treatment of the inner wall of the processing chamber through the suction pipe at the output end to discharge the air. Before being discharged, the exhaust gas will pass through the surface of the cylindrical sieve plate to perform the final treatment on the exhaust gas. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] A pulley 2 is fixedly mounted on the bottom of the fixed plate 1. There are four pulleys 2. The four pulleys 2 are of equal shape and size. The four pulleys 2 are respectively fixedly mounted at the four corners of the bottom of the fixed plate 1.

[0040] A processing chamber 3 fixedly mounted on the top of the fixed plate 1;

[0041] and a processing assembly 4 disposed at the top of the fixed plate 1;

[0042] The processing assembly 4 includes a processing mechanism 41 installed at the top position of the fixed plate 1;

[0043] A filtering mechanism 42 is installed at the top of the fixed plate 1, and the filtering mechanism 42 is located at the left side of the processing mechanism 41;

[0044] An auxiliary mechanism 43 is installed at the top of the fixing plate 1 , and the auxiliary mechanism 43 is connected to one end of the processing mechanism 41 .

[0045] The processing mechanism 41 includes a motor 411, which is fixedly installed on the right side wall of the processing chamber 3. The motor 411 passes through the side wall of the processing chamber 3 and extends to the inner wall of the processing chamber 3 through the rotating shaft at the output end. A rotating rod 412 is installed for transmission. One end of the rotating rod 412 is rotatably connected to the inner wall of the processing chamber 3 through a bearing. A bevel gear 1 413 is fixedly installed on the side wall of the rotating rod 412, and a bevel gear 2 414 is installed on the side wall of the bevel gear 1 413. There are two bevel gears 2 414. A long rod 418 is fixedly installed on the bottom of the bevel gear 2 414 located on the left side, and a stirring block 419 is fixedly installed on the bottom of the long rod 418. A rotating rod 415 is fixedly installed on the bottom of the bevel gear 2 414 located on the right side, and a horizontal plate 416 is fixedly installed on the bottom of the rotating rod 415. A brush 417 is fixedly installed on the bottom of the horizontal plate 416, and a cylindrical screen plate 4110 is provided in contact with the bottom of the brush 417.
