Description

Technical Field

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

[0002] Bag filter is a dry dust filter device 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 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] In the prior art, the dust collector upper cover with multiple feed ports is generally made of multiple cut flat plates welded together. The welding workload is large and the working hours are long. In addition, the product quality is greatly affected by the welding quality and is difficult to control. Not only is the cost high, but the yield rate is also low. Utility Model Content
