AI Technical Summary
In existing waste gas treatment devices, the cleaning brushes wear down after prolonged use, making it impossible to effectively clean the outer or inner wall of the rotating drum. This leads to blockage of the air inlet, affecting the normal operation of the device and increasing replacement costs.
A waste gas treatment device including a filter box, a purification component, and a spray component was designed. By turning the handle, the rotating rod and the bidirectional lead screw are driven to move the bristles relative to each other, ensuring contact with the rotating cylinder. In conjunction with the motor driving the rotating cylinder to rotate, the rotating cylinder is effectively cleaned, and the bristles are easy to disassemble and replace.
It effectively prevents air inlet blockage, reduces the frequency of brush replacement due to wear, reduces operating costs, and improves the operational stability and maintenance convenience of the device.

[0040] The principle of the embodiment of the application is that the motor 12 is controlled to work to drive the square block 14 to rotate, the square block 14 is inserted into the square groove 13, so that the square block 14 can drive the rotating cylinder 17 to rotate when rotating, the rotating cylinder 17 rotates along the brush 20, and then the large particles on the side of the rotating cylinder 17 are cleaned through the brush 20, so that the large particles cannot block the air inlet hole 18, and the rotating cylinder 17 can continuously filter the exhaust gas;
