Description

Technical Field

[0001] The utility model relates to the field of bag dust collectors, in particular to a dust cleaning device for a bag dust collector. Background Art

[0002] A bag dust collector is a dry dust filtering device, which is suitable for collecting fine, dry and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the dust-containing gas is filtered by the filtering action of the fiber fabric. When the dust-containing gas enters the bag dust collector, dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, and the gas is purified. A bag dust collector is a dry dust filtering device. After the filter material is used for a period of time, due to effects such as sieving, collision, retention, diffusion, and static electricity, a layer of dust accumulates on the surface of the filter bag. This layer of dust is called the primary layer. In the subsequent movement process, the primary layer becomes the main filtering layer of the filter material. Relying on the action of the primary layer, a filter material with larger mesh holes can also obtain a higher filtering efficiency.

[0003] However, in the existing market, during the use of the bag dust collector, a large amount of dust is easily attached to the inside of the ash hopper. When the dust accumulates thickly, it is easy to cause the ash hopper to be blocked, and it is not convenient to clean the dust inside the ash hopper, which affects the working efficiency of the cloth belt dust collector.

[0004] Therefore, it is necessary to provide a dust cleaning device for a bag dust collector to solve the above technical problems. Summary of the Invention

By the operation of the first motor 4, the first guide rod 5 is effectively driven to rotate. The first guide rod 5 drives the rotating rod 6 to rotate, the rotating rod 6 drives the connecting rod 7 to rotate, the connecting rod 7 drives the brush 8 to rotate, and the brush 8 effectively cleans the dust adhering to the surface of the dust accumulation hopper 2.
