Air filtering device for chemical production

The utility model discloses an air filtering device for chemical production, which relates to the technical field of chemical engineering and comprises a device body, a vibrating mechanism is arranged on one side of the inner wall of the device body and comprises a driving shaft, one end of the driving shaft is fixedly connected with the middle of one side of a driven plate, and a rocker is fixedly arranged on the other side of the driven plate. The outer circumferential face of the rocker is in sliding connection with the outer circumferential face of the stop lever. A driving shaft can be driven to rotate through external power, the driving shaft further drives a shifting rod on one side of a driven plate to do work on a stop rod, the stop rod drives a driven rod to compress a reset spring on a supporting column, the driven rod further ascends under the acting force of the reset spring, the driven rod collides and makes contact with a supporting frame, and therefore the supporting frame can be driven to rot
