Background
Along with the rapid development of economy, the living standard of people is increasingly improved, the national requirements on the air quality control are increasingly strict, and higher requirements on the performance and the reliability of dust removal equipment are provided. Because the pulse blowing bag type dust collector has high dust removal efficiency, the pulse blowing bag type dust collector is widely adopted. The pulse blowing cloth bag type dust collector mainly comprises a filter bag, a bag cage, a pattern plate, a bag chamber, an air purifying chamber, an air inlet and outlet channel, an ash cleaning system, an ash conveying system and the like.
The pattern plate may also be referred to as a multi-plate hole. The pattern plate is used for hanging the filter bag, and a bag chamber containing dust-containing gas is separated from a clean air chamber through the hung filter bag.

In addition, in order to improve the sealing performance between the filter bag and the dust collector pattern plate and ensure the verticality of the filter bag and reduce the inclination of the filter bag during installation, a mode of additionally arranging a short pipe is adopted in the prior art, and the short pipe and the dust collector pattern plate are both subjected to hot welding and full welding of a welding line. This may cause a problem that the pattern plate is deformed excessively. In order to prevent the problem of deformation of the pattern plate due to hot full welding, the pattern plate needs to be additionally provided with complex reinforcing ribs, and the pattern plate and the short pipe are subjected to hot full welding by using a special welding auxiliary tool fixture, so that the manufacturing cost is greatly increased.
5. When the ash removal and filtration of the long filter bag are switched, the phenomena of deflection, swing, mutual collision and the like are easy to occur, so that the lower part of the filter bag is damaged early, and the discharge exceeds the standard; in addition, the filter bag swings, deflects, even is piled up together and other problems occur, the effective filtering area of the dust remover is reduced, and the filtering efficiency of the dust remover is reduced.
Most of the filter bags of the traditional pulse blowing type bag dust collector are manually installed and replaced one by one at the top of the dust collector at the site, so that the problems of high labor intensity, low working efficiency, unsafety, easy secondary pollution to the surrounding environment of the dust collector and the like exist.
