Description

Technical Field

[0001] The utility model belongs to the technical field of pulse bag dust collectors, and in particular relates to a quick bag replacement mechanism for a pulse bag dust collector. Background Art

[0002] The pulse bag dust collector is a new type of high-efficiency pulse bag dust collector improved on the basis of the bag dust collector. In order to further improve the pulse bag dust collector, the modified pulse bag dust collector retains the advantages of high purification efficiency, large gas processing capacity, stable performance, easy operation, long filter bag life, and small maintenance workload. It also reforms the structure and pulse valve to solve the problems of open-air placement and low compressed air source pressure.

[0003] During the use of the pulse bag dust collector, dust is removed by combining the inside of the dust barrel with the partition and the dust bag, which can quickly and massively remove the smoke and dust exhaust gas generated by industrial production. In the process of large-scale exhaust gas treatment, the surface of the dust bag is contaminated with dust at a fast rate, so the dust bag needs to be replaced regularly. Since the bag is continuously impacted by the up and down airflows inside the dust collector box, bolts are used to assist in stable installation to ensure the stability of the bag. However, there is a problem of slow replacement speed. At the same time, the bolts will become loose after multiple replacements, affecting the stability of the device. Utility Model Content
