Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collector replacement technology, and in particular to a replacement structure for a bag filter dust collector. Background Technology
[0002] A baghouse dust collector is a dry dust filtration device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle down due to gravity and fall into the ash hopper. The gas containing finer dust particles is purified as it passes through the filter media, as the dust is trapped.
[0003] Replacing existing filter bags is quite troublesome. Filter bags are usually fixed with bolts, which makes it difficult to quickly replace them when it is necessary to disassemble them for dust removal. Therefore, a structure that allows for quick replacement of dust collector filter bags is needed. Utility Model Content
