A vibration knocking device is provided on the filter cover 11. The filter cover 11 performs a second layer of filtration on the exhaust gas, and the filtered particles adhere to the filter cover 11, and the particles are knocked down by the vibration knocking device to prevent the particles from gathering and clogging the filter holes.

In this embodiment, the vibration knocking device includes a fixed shaft 22 connected to the inner wall of the processing box 1, and a torsion spring 23 is sleeved on the fixed shaft 22. The two ends of the torsion spring 23 are respectively connected to the V-shaped rod 18 and the processing box 1. The V-shaped rod 18 is rotatably sleeved on the fixed shaft 22, and the end of the V-shaped rod 18 is connected to a knocking head 21 on the side close to the filter cover 11, and the side of the V-shaped rod 18 away from the knocking head 21 is connected to an armature 20. The inner wall of the processing box 1 is connected to an electromagnet 19 corresponding to the armature 20. The electromagnet 19 is controlled by an intermittent switch.

In this case, the exhaust gas flows from the air inlet end of the treatment box 1 to the air outlet end. During this process, the filter belt 7 realizes the first layer of filtration. The servo motor drives the filter belt 7 to rotate back and forth, and uses different positions of the filter belt 7 for filtering. The dust box 9 sucks in the particles attached to the filter belt 7, cleans the filter belt 7, and discharges them in a centralized manner, thereby extending the service life of the filter belt 7 and improving the filtration efficiency. The filter cover 11 performs the second layer of filtration on the exhaust gas. When the exhaust gas blows toward the baffle plate 14, the baffle plate 14 moves back and forth under the action of the cam 4, and blows the exhaust gas evenly toward the activated carbon block 16, so that the particles in the exhaust gas are evenly gathered on the surface of the activated carbon block 16.
