Description

Technical Field

[0001] The utility model relates to the technical field of dust collection, in particular to an automatic dust collector. Background Art

[0002] The automatic dust collector is a dry dust filtering device suitable for capturing fine, dry, non-fibrous dust. It filters the dust-containing gas by using a filter element made of textile filter cloth or non-textile felt. When the dust-containing gas enters the bag filter, it will first flow downward after being blocked by the dust shield. At this time, the heavier particles fall into the dust collecting port below, and the lighter flue gas floats upward and is filtered through the filter element. However, in the existing dust collector, there is no corresponding flow equalization structure after the flue gas passes through the dust shield, resulting in most of the flue gas being filtered through the filter element close to the dust shield side, while the bottom of the filter element far away from the dust shield cannot be fully utilized, affecting the actual filtering effect of the filter element.
