s3: the gas after secondary filtration is sent into the air storage cylinder (15) through the snake skin metal hose (20), along with the increase of the sent gas, the piston plate (16) pulls the tension spring (18) to slide in the air storage cylinder (15), when the gas slides, the piston rod (17) is driven to extend, in the extension process, the rotary table (19) is driven to rotate, the torsion spring (22) is driven to tighten in the rotation process of the rotary table (19), when the gas extends to the farthest point, the piston plate (16) slides to the gas outlet end of the air storage cylinder (15), the high-pressure gas in the air storage cylinder (15) is sent to the outside of the case (1) through the gas outlet hose (21), at the moment, the pressure in the air storage cylinder (15) is reduced, the tension spring (18) rebounds under the effect of the rebounding force, the torsion spring (22) rebounds, the rotary table (19) is driven to reciprocate, the transmission rod (8) and the first metal net rotating rod (5) are further driven to reciprocate, when the first metal net (5) reciprocates, the mesh rod (10) and the second metal net (6) are matched along the mesh (9), dust cleaning cloth bag is removed, and dust falls into the inner wall of the dust cleaning bag (7);
s4: and opening the electric valve (13), enabling deposited dust at the dust removing port to fall into the dust deposition frame (26), and then closing the electric valve (13) to disassemble the dust deposition frame (26) filled with the deposited dust for centralized treatment.
2. The use method of a cloth bag dust collector according to claim 1, characterized in that the top of the filtering baffle plate (4) is fixedly connected with uniformly distributed annular nut seats (27) which are sleeved outside the opening, the outer side wall of each annular nut seat (27) is provided with a threaded part, the threaded part is in threaded connection with a screw pipe (28), and the bottom of the cloth bag (7) is fixedly connected between the threaded part and the screw pipe (28).
3. The use method of the cloth bag dust removal device according to claim 2, wherein the rotating rod (9) and the ash removal rod (10) are both hollow structures, and the outer side wall of the ash removal rod (10) is provided with a brush layer.
