Description

Technical Field

[0001] The utility model relates to the technical field of cloth bag skeletons, and more specifically, it relates to a cloth bag skeleton for a bag dust collector. Background Art

[0002] A bag dust collector is a dry dust filtering device, which is suitable for collecting fine, dry and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the dust-containing gas is filtered by the filtering action of the fiber fabric. When the dust-containing gas enters the bag dust collector, dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained and the gas is purified. Inside the bag dust collector, the cloth bag is usually sleeved on the cloth bag skeleton, and the cloth bag is supported by the cloth bag skeleton.

[0003] Most of the existing cloth bag skeletons of bag dust collectors are welded by multiple rings and steel wires, and a barrel shape is formed by multiple steel wires and rings. Usually, the cloth bag skeletons of corresponding sizes are welded according to the diameter and length of the cloth bag. The existing bag dust collectors are not convenient for corresponding adjustment between them, not convenient for supporting cloth bags of different diameters, and in addition, it is not convenient to appropriately adjust their lengths and not convenient for supporting cloth bags of various different lengths, reducing the practicability of its use.
