The upper and lower ends of the moving filter plate 6 and the fixed filter plate 5 are fixed with blocks 9. The lower block 9 is fixed to the bottom of the cavity.

[0029] One of the chambers has a sealing plate 10 installed at its upper end, and multiple collection hoppers 11 for collecting clogging particles are installed at its lower end. Upper clamping blocks 9 are fixed to the sealing plate 10. An annular tube 12 for cleaning the ejector pin 8 is also fixed to the lower end of the sealing plate 10. Nozzles 13 are evenly spaced at the bottom of the annular tube 12. Guide posts 14 for guiding the filter plate 5 are fixed to the upper and lower adjacent clamping block 9 supports. Considering that the exhaust gas contains various types of dust, the filter screen is prone to clogging after long-term use, affecting the gas flow within the activated carbon adsorption box and reducing the efficiency of the activated carbon adsorption box in treating the exhaust gas. This device will use... The horizontally movable filter plate 6 cleans and unblocks the sieve holes of the fixed filter plate 5 and the moving filter plate 6. When the moving filter plate 6 moves horizontally, the pin 8 will clean and unblock the filter holes 7 of the fixed filter plate 5 during the horizontal movement of the moving filter plate 6. In addition, the sieve holes of the moving filter plate 6 will be unblocked and cleaned by the pin 8 on the fixed filter plate 5 during the horizontal movement of the moving filter plate 6. The cleaned dust particles and the dust particles attached to the surface of the pin 8 will be cleaned by the airflow sprayed from the nozzle 13 at the lower end of the annular pipe 12. The dust particles blown to the bottom of the cavity will be transported to the inside of the dust collection bag 20 for storage by the negative pressure generated by the collection hopper 11 and the fan 17.

[0030] One of the chambers is equipped with an activated carbon adsorption box 15. An exhaust pipe 16 is installed on the other side of the activated carbon adsorption box 15.

The middle of the fixing ring 29 is threadedly connected to a positioning bolt 30 for mounting the electric push rod 28, and the telescopic end of the electric push rod 28 is fixed to the U-shaped rod 25. The electric push rod 28 drives the U-shaped rod 25. When the telescopic end of the electric push rod 28 extends or retracts, the U-shaped rod 25 will cause the filter plate 6 to move horizontally along the guide column 14.

[0035] The upper end of the sealing plate 10 is also provided with a reserved hole for the installation of two air injection pipes 31. The bottom of the two air injection pipes 31 is connected to the annular pipe 12, and the top of the two air injection pipes 31 is connected to the same three-way pipe 32. The upper end of the three-way pipe 32 is connected to the air injection end of the air pump 33 through a pipe. The air pump 33 is fixed to the upper end of the processing pipe 2 through the mounting box. The upper end of the air pump 33 passes through the top of the mounting box through a pipe and is installed with the dustproof mesh cover 34. By setting the air pump 33, the annular pipe 12 is injected with air. During the process of sending the external gas into the air injection pipe 31, it will first be filtered by the dustproof mesh cover 34, and then sprayed out by the nozzle to clean the dust particles attached to the surface of the ejector pin 8.
