Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a dust removal system. Background Art

[0002] The filter bag of the bag filter is made of textile filter cloth or non-textile felt. It uses the filtering effect of fiber fabric to filter the dust-containing gas. Therefore, it is suitable for capturing fine, dry, non-fibrous dust and is often used for the treatment of industrial waste gas.

[0003] However, after long-term use, a large amount of dust will be adsorbed on the filter bag, resulting in a decrease in the filtration efficiency of the filter bag. However, the bag dust collector equipment is large and inconvenient to clean, and the conventional vibration motor vibration cleaning has unsatisfactory cleaning effect.

[0011] The top surface of the second tube body is fixedly connected with a third tube body, and the diameter of the third tube body is greater than the diameter of the first tube body. The third tube body is located above the first tube body, and the bottom surface of the third tube body is placed on the top surface of the first tube body;
