AI Technical Summary

Technical Problem

In existing dust collection devices for air jet mills, the filter surface of the filter bags is used unevenly. The filter bags closer to the air inlet are clogged prematurely, while the filter bags farther from the air inlet have low utilization rates, resulting in a shortened overall lifespan of the filter bags.

Method used

A dust removal device comprising a revolution unit and a rotation unit was designed. The filter bags are driven to revolve as a whole by a sealed partition, and each filter bag rotates independently and intermittently. Combined with a pulse cleaning mechanism, the filter bags are used evenly and cleaned efficiently.

Benefits of technology

This achieves balanced use of filter bags, extends their service life, improves filtration efficiency and utilization, and reduces operating costs.

Abstract

This invention discloses a dust removal device for an air jet mill used in bactericide production, relating to the field of bactericide production technology. It includes a filter chamber and a feeding chamber, and further includes: a dust removal mechanism disposed inside the filter chamber; and a pulse cleaning mechanism disposed on the top surface of the filter chamber. The dust removal mechanism includes a sealing partition, a movable tube, a filter bag, a revolution unit, a rotation unit, and a locking component. Through the coordinated operation of a driven gear, a driving gear, a second drive motor, a support plate, a sliding column, a movable groove plate, a sliding groove, and a pulse tube, the second drive motor can be periodically activated during the filtration process. Through the meshing transmission of the driving gear and the driven gear, and the intermittent engagement of the sliding column and the sliding groove, each movable tube drives the corresponding filter bag to rotate independently and intermittently, allowing multiple filter surfaces of each filter bag to rotate sequentially to the air inlet side, achieving the effect of evenly utilizing the entire outer circumference of a single filter bag.
