Description

Technical Field

[0001] The utility model relates to the technical field of bag dust removal, and more specifically, to a bag dust removal machine. Background Art

[0002] The bag filter is a dry dust filter. It is suitable for capturing fine, dry, non-fibrous dust. The dust 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 filter, the large particles and heavy 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] The dust bag assembly of the existing bag type dust collector has a fixed filtering area and poor filtering effect. In addition, the dust bag assembly is often difficult to clean due to its fixed connection mode, and needs to be disassembled and cleaned repeatedly, which is quite inconvenient.

[0004] In order to solve the above problems, the utility model with publication number CN209997332U discloses a bag filter assembly for a bag-type dust collector. The pleated design increases the filtering area. At the same time, the pleated dust filter bag has better flexibility. Under the action of the pulse, the dust is easy to shake off and not easy to collect dust, which reduces the number of times the dust filter bag is disassembled and assembled, and improves the filtering effect. The circular ring support plate can rotate in the outer support seat, and the lower ring frame can rotate around the lower connecting seat. Under the action of the pulse, the support rod rotates with the dust filter bag to achieve uniform contact between the dust filter bag and the pulse, improve the filtering effect, and at the same time, during the rotation of the dust filter bag, it is easy to shake off the dust, achieving the filtering effect and playing a cleaning role.

[0005] When the above-mentioned bag dust collector dust bag assembly is actually used, a certain amount of dust will accumulate in the ash hopper, making the air inlet smaller, which may cause the air inlet to be blocked and may cause wear on the filter bag, thereby shortening the service life of the filter bag and reducing the working efficiency of the dust collector.
