Description

Technical Field

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

[0002] The filter bag is made of textile filter cloth or non-textile felt. It uses the filtering effect of fiber fabric to filter the 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, a layer of dust will accumulate on the surface of the filter bag. If the dust accumulated on the filter bag is not processed, the filtering effect will be affected. The current bag dust collector cannot effectively remove the dust adhered to the bag body during use, which will affect the filtering effect of the filter bag. In view of the above problems, the inventor proposes a dust bag dust collector to solve the above problems. Utility Model Content
