Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a bag installation structure of a bag dust collector. Background Art

[0002] The bag dust collector is a dry dust filtering device, which is suitable for capturing fine, dry, non-fibrous dust. The filter 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 dust collector, the large particles and high specific gravity 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 and the gas is purified. The filter bag diameter and length of the existing cloth dust collector are fixed, which cannot meet the installation requirements of equipment of different sizes, and the dust on the outer wall of the filter bag is not cleaned thoroughly. In order to solve the above problems, a cloth bag installation structure for a cloth dust collector is needed.

[0003] The existing bag installation structure of a bag dust collector cannot meet the installation requirements of bags of different diameters and lengths during operation, and the dust cleaning effect on the outer wall of the bag is poor. Therefore, a bag installation structure for a bag dust collector is urgently needed. Utility Model Content

The outer wall of the filter bag is installed with a fixing sleeve, the inner wall of the fixing sleeve is installed with a limiting plate, and the bottom of the fixing sleeve is installed with a base.

[0008] Preferably, the clamping plate is movably connected to the fixed plate, and the clamping plate forms a telescopic structure with the fixed plate via a return spring.

[0009] Preferably, the filter bag is threadedly connected to the ferrule, and the fixing blocks are distributed in a circular array with the central axis of the filter bag as the center.
