Description

Technical Field

[0001] The utility model relates to the technical field of bag dust removal, in particular to a back-blowing bag dust collector. Background Art

[0002] Bag filter, also known as bag dust collector, is a dry dust filtering device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter dust-containing gas. When the dust-containing gas enters the bag dust collector, the large particles and heavy dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

[0003] After the bag dust collector has been used for a period of time, the staff needs to maintain the bag dust collector and take out the filter bags for cleaning or replacement. However, the filter bags of commonly used bag dust collectors are individually fixed by spring clips, which makes it cumbersome for the staff to remove the filter bags, affecting maintenance efficiency.
