Description

A kind of flame retardant dust collector bag

Technical field

The utility model relates to the technical field of dust removal, specifically a flame-retardant dust collector bag.

Background technique

Bag dust collector is a dry dust filter device, which is suitable for collecting fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt. The filtering effect of fiber fabric is used to filter dust-containing gas. When the dust-containing gas enters the bag dust collector, the dust with large particles and heavy specific gravity will be removed due to the effect of gravity. It first settles down and falls into the ash hopper. When the gas containing finer dust passes through the filter bag, the dust is blocked on the outer surface of the filter bag, allowing the gas to be purified.

For example, the public document with application number CN201910856668.9 discloses a bag dust collector. Through the cooperative use of filter components, dust cleaning structures, annular elastic parts, connectors and cam mechanisms, during dust cleaning, due to the rotation of the cam, , push the connecting piece to move in the direction away from the filter assembly, and the connecting piece pulls the annular elastic member to deform/rebound at intervals, so that the outside of the filter assembly is subjected to a slap-like effect, which can then slap the dust on the outer wall of the filter assembly. Remove and reduce dust adhering to the outer wall of the filter assembly, thereby improving the dust cleaning effect of the filter bag and extending the filter bag replacement cycle. However, this utility model is inconvenient to replace the dust bag, and the replacement process is relatively complicated.

Therefore, in view of this, the existing structural deficiencies were studied and improved, and a flame-retardant dust collector bag was proposed.
