AI Technical Summary
Existing dust removal devices for silicon micropowder processing have a simple structure, making it difficult to simultaneously achieve graded filtration of coarse and fine dust. They are also prone to filter plate clogging, uneven mixing, and cleaning difficulties, resulting in low dust removal efficiency and a large workload for equipment maintenance.
Design a dust removal device that includes coarse and fine filter plates, and combine a differential rotation mechanism to drive scrapers and stirring columns to achieve graded filtration of coarse impurities and fine dust, and inject high-pressure air through high-pressure nozzles to prevent dust accumulation.
It achieves efficient separation of coarse particulate impurities and fine dust, improves filtration efficiency, reduces filter plate clogging and cleaning difficulty, and enhances equipment operating efficiency and maintenance convenience.
