Description

Technical Field

[0001] The utility model relates to the technical field of bag cages, in particular to a convenient bag-changing bag cage. Background Art

[0002] The filter bag is an indispensable and important part of the bag dust collector and the electric bag composite dust collector. When the dust-containing flue gas passes through the filter bag, the dust in the flue gas is retained on the surface of the filter bag to achieve the purpose of dust removal. At present, most of the filter bags adopt an external filtration structure. In order to keep the filter bag in a certain shape during the dust filtering and cleaning process, a bag cage is required to support it. The filter bag has to withstand a large gas pressure during the filtering and cleaning state. In order to prevent the filter bag from separating from the bag cage, the two are often required to be tightly connected together. However, the connection method between the filter bag and the bag cage in the prior art is very troublesome, which makes the replacement of the filter bag time-consuming and labor-intensive, and is very inconvenient to use. For this reason, we propose a bag cage that is easy to change bags. Utility Model Content
