Description

Technical Field

[0001] The utility model relates to the field of bag dust collectors, in particular to an auxiliary dust cleaning device for bag dust collectors. Background Art

[0002] Bag filter is a dry dust filter. 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 filter, the dust with large particles and high specific gravity settles down due to gravity and falls 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. After the filter material has been used for a period of time, a layer of dust accumulates on the surface of the filter bag due to the effects of screening, collision, retention, diffusion, static electricity, etc., so a bag filter auxiliary cleaning device is needed.
