Dust collector filtering bag component and cloth bag dust collector

Abstract

The invention discloses a dust collector filtering bag component and a cloth bag dust collector. The dust collector filtering bag component comprises filtering bags and a cage framework, wherein the filtering bags comprise an external filtering bag body, an inner filtering bag body and a connecting bag body, so that four cylinder-shaped filtering surfaces are formed; the cage framework comprises an upper flange cylinder, an outer support rod, an inner support rod and an inner sleeve rod; the outer support rod is inserted between the external filtering bag body and an outer connecting bag wall; the inner support rod is inserted between the inner filtering bag body and an inner connecting bag wall; a circular pressing plate is fixed at the upper end part of the inner sleeve rod; the upper end of the inner sleeve rod penetrates through the inner sealing plate and is fixed through a screw nut; the pressing plate is matched with an inner sealing plate part to press the upper sealing part of the inner filtering bag body; the lower end of the inner sleeve rod is bent upwards to form a support rod section; the support rod section is used for supporting the inner connecting bag wall of the connecting bag body. Compared with a conventional filtering bag component, the dust collector filtering bag component has the advantages that the filtration area is increased and the filtration efficiency is improved.

Description

technical field [0001] The invention relates to a filter bag assembly, in particular to a filter bag assembly of a dust collector, and simultaneously the invention also discloses a bag dust collector equipped with the filter bag assembly. Background technique [0002] The bag filter is a dry dust filter device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt, and uses the filter function of the fiber fabric to filter the dusty gas. When the dusty gas enters the bag filter, the dust with large particles and large specific gravity will When the air containing fine dust passes through the filter material, the dust will be blocked and the air will be purified. In order to improve the efficiency of filtration and purification, two methods are usually adopted: 1. Increase the diameter of the filter bag; 2. Increase the length of the filter bag, and both of these methods will increase the volume of the ent...
