A plurality of positioning shafts 73 are provided for rotation, the positioning shafts 73 are connected to the guide vanes 74, the guide vanes 74 are provided with a plurality of through holes, the guide vanes 74 are provided with a counterweight block 72, the filter ring body 67a is provided with a avoidance groove 67a1 matching the guide vanes 74, the cylinder 2 62 is fixed to the upper part of the processing box 59, the piston rod of the cylinder 2 62 is vertically downward, the piston rod end of the cylinder 2 62 is connected to the lifting frame 61, the lifting frame 61 is fixed with a drive motor 65, the drive motor 65 The output shaft end is connected to the positioning block 66, the brush roller 60 is horizontally rotatably installed on the positioning block 66, and the brush roller 60 can contact the filter plate 67, the cylinder three 56 is fixed to the lower part of the processing box 59, the piston rod of the cylinder three 56 is vertically upward, and the piston rod end of the cylinder three 56 is fixed with a support frame 70 for supporting the filter ring body 67a, and the support frame 70 is located in the processing box 59; in this embodiment, the filter plate 67 adopts an existing product available on the market.

[0059] With this structure, when the filter plate 67 filters the smoke entering the processing box 59 from the outlet pipe 63, since the filter plate 67 is composed of a plurality of filter ring bodies 67a, and two adjacent filter ring bodies 67a are sealed and connected by elastic bodies 67b, under the action of its own gravity, the entire filter plate 67 will form a downwardly concave structure, and the guide plate 74 is in a vertical state under the action of the counterweight block 72. During the downward flow of smoke entering the processing box 59 from the inlet pipe, the airflow generated by the smoke will continuously hit the guide plate 74, and the guide plate 74 will cause the corresponding filter ring body 67a to slightly shake. The movement can prevent the smoke dust in the smoke from sticking to the filter plate 67, and the treatment is reliable; after the treatment box 59 has been used for a period of time, the support frame 70 is driven to move upward by the cylinder three 56, and the support frame 70 contacts the filter ring body 67a, so that each filter ring body 67a is located on the same plane, and the guide plate 74 is in a horizontal state. The counterweight block 72 can be located under the action of the avoidance groove 67a1, and is driven to move downward by the cylinder two 62. The lifting frame 61 makes the brush roller 60 contact the filter plate 67 forming a plane, and the brush roller 60 is driven to rotate by the stepping motor 26, and the smoke dust on the filter plate 67 is swept away by the brush roller 60.

[0060] By opening the solenoid valve 69, the smoke on the filter plate 67 can be temporarily collected in the collection box 57, replacing the conventional need to frequently take out the filter plate 67 for cleaning.

[0061] The side of the processing box 59 has a cleaning port, and the cleaning port is located below the filter plate 67. The processing box 59 is hinged with a box door 58 that can close the cleaning port.

[0062] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0063] In addition, those skilled in the art may also make other changes within the spirit of the present invention. Of course, these changes made according to the spirit of the present invention should be included in the scope of protection required by the present invention.
