Description

Technical Field

[0002] Bag dust collector is a dry dust filtering device, which is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, the large particles and high specific gravity dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

[0003] In the prior art, a utility model patent with publication number CN214551894U provides a built-in cyclone bag dust collector, which belongs to the technical field of dust removal devices. It includes a device shell, a fixed frame is arranged in the device shell, and a plurality of dust removal filters are fixedly connected in the fixed frame. The fixed frame is clamped in a support plate, and the outer wall of the support plate overlaps the inner wall of the device shell, and the left and right sides of the support plate are fixedly connected with sliders.

[0004] The built-in cyclone bag dust collector has a poor effect of filtering and collecting dust particles by letting the dust particles fall by their own gravity, and the dust in the dust gas is not cleaned thoroughly. Therefore, we propose a built-in cyclone bag dust collector to solve the above problems. Utility Model Content
