Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to an air intake device. Background Art

[0002] In life, the dust bag is the heart of the bag dust collector, generally called the dust bag or dust filter bag. The dust bag is the key part of the operation of the bag dust collector. Usually the round filter bag is hung vertically in the dust collector. The fabric and design of the dust bag should strive for high-efficiency filtration, easy dust removal and durability. The washing of the dust bag is very important, which directly affects the dust removal effect of the dust collector. The selection of dust bags is based on the following aspects: gas temperature, humidity and chemistry, particle size, dust concentration, filtration wind speed, dust cleaning method and other factors.
