Description

Technical Field

[0001] The utility model relates to the field of dust collectors, and more specifically, to a bag dust collector with convenient filter bag replacement. Background Art

[0002] Dust collectors are very common in industrial production. Dust collectors are used to filter the gases that need to be used. Filter bags are important components in dust collectors. When the dust collector is in use, the gas is filtered through the filter bags to block dust on the outside of the filter bags. The filtered gas passes through the filter bags to complete the filtration of the gas. The existing filter bags are fixed to the dust collectors by bolts and other parts. When the operator replaces the filter bags, it is necessary to use corresponding tools to remove the bolts, etc., which takes a lot of time and is inefficient when replacing the filter bags. At the same time, the existing dust collectors lack a cleaning structure. When the filter bags are used and do not need to be replaced, the surface of the filter bags needs to be cleaned when the filter bags are used again to facilitate filtering by the filter bags. The lack of a cleaning structure will cause dust to accumulate on the surface of the filter bags, affecting the filtering effect on the gas. Utility Model Content
