9. The process for coating a low concentration exhaust gas treatment device according to any one of claims 1 to 8, comprising the steps of:
the equipment is placed at a proper position, a suction fan (11) is started, the suction fan (11) generates suction force, waste gas generated during coating can be sucked into a shell (3) through a suction hood (14), a connecting pipe (13), an air suction pipe (12) and an air outlet pipe (15), dust or other particles in the waste gas can be filtered out under the action of a filter screen plate (4), after the waste gas passes through the filter screen plate (4), harmful substances in the waste gas can be adsorbed under the action of the active carbon filter plate (9), and then clean gas can be discharged from an exhaust pipe (16);
S2, when the mesh of the filter screen plate (4) is blocked and the ventilation effect is affected, a stepping motor (807) is started, the stepping motor (807) can drive a cam (808) to rotate, and the cam (808) can make two sliding plates (803) do left-right reciprocating motion in the horizontal direction in cooperation with the elastic force of a second spring (804), the sliding plates (803) can drive corresponding U-shaped rods (805) to do left-right reciprocating motion, the U-shaped rods (805) can drive corresponding connecting rods (806) to move, the two connecting rods (806) can drive an H-shaped connecting plate (5) to do up-down reciprocating motion, the H-shaped connecting plate (5) can drive a vibrating plate (7) to do up-down reciprocating motion through a first spring (6), so that the filter screen plate (4) can be beaten, and the meshes of the filter screen plate (4) can be dredged;
S3, when more dust is accumulated in the shell (3), the electric push rod (1705) is started, the ejection end of the electric push rod (1705) stretches out to drive the connecting piece (1706) to move, the connecting piece (1706) can drive the plugging plate (1704) to move, so that the dust exhaust pipe (1703) can be opened, then the servo motor (1702) is started, the servo motor (1702) can drive the auger (1701) to rotate, and the auger (1701) can push out the dust accumulated in the shell (3) from the port of the dust exhaust pipe (1703).
