AI Technical Summary

Technical Problem

Existing dust removal devices in cement processing prevent dust from adhering by tapping the filter bags, but this can easily lead to damage to the filter bags and affect the filtration effect.

Method used

Dust is drawn in by a negative pressure fan, filtered through dust collector filter bags, and falls into the dust hopper while the gas is discharged. When dust adheres to the filter bags and reduces their efficiency, an air jet pipe blows air onto the filter bags to remove the dust. When a filter bag is damaged, a cylinder opens the top cover for easy replacement.

Benefits of technology

It achieves effective dust filtration and filter bag cleaning and maintenance, prevents filter bag damage, maintains good filtration effect, and simplifies the filter bag replacement process.
