Dust removal mechanism

The dust removal mechanism comprises a lower barrel body, an upper barrel body and exhaust pipelines, the upper barrel body is arranged at the top of the lower barrel body, the exhaust pipelines are symmetrically arranged at the top of the upper barrel body, and a water collection box is arranged on the inner side of the upper barrel body relative to the bottom of the exhaust pipelines. Two lifting assemblies are symmetrically arranged on the two sides of the lower barrel body, and each lifting assembly comprises a supporting block, an air cylinder and an ejection block; through the designed structures such as a supporting block, an air cylinder, a top block, a metal block and a positioning hole, the upper barrel body is lifted upwards by a certain height through the air cylinder, so that the barrel body is quickly opened, and a worker can conveniently clean the interiors of the lower barrel body and the upper barrel body, and meanwhile, through the designed structures such as a fixing frame, a mounting ring,
