Description

Technical Field

[0001] The invention relates to the technical field of dust collectors, and in particular to an air bag structure of a novel bag type dust collector. Background Art

[0002] Bag filter is a dry dust filter. After the filter material has been used for a period of time, a layer of dust accumulates on the surface of the filter bag due to the effects of screening, collision, retention, diffusion, static electricity, etc. This layer of dust is called the primary layer. In the subsequent movement process, the primary layer becomes the main filter layer of the filter material. Relying on the effect of the primary layer, the filter material with a larger mesh can also obtain a higher filtration efficiency. The bag filter includes an air bag structure and a frame.

[0003] However, the various components of some air bag structures are connected to the air bag tube by welding. The structural performance of the air bag structure is easily damaged during the welding process, and the sealing performance of the welding joints needs to be tested. Generally, the water sealing test of the air bag structure as a whole is performed with a test liquid. In addition, since the structure of the air bag structure is too large, the assembly process is more cumbersome.
