Dedusting filter bag based on alkali-free expanded glass fiber cloth

Abstract

The invention discloses a dust removal filter bag based on alkali-free expanded glass fiber cloth, which comprises a filter bag body, the filter bag body is composed of an outer filter screen, a support screen, an inner filter screen and a net rack, a hoop is clamped and mounted at the top end of the filter bag body, a locking bar is mounted in the hoop, a lock catch is clamped and mounted on one side of the hoop, and a sealing cover is hinged and mounted on the front side of the lock catch. According to the dust removal filter bag based on the alkali-free bulked glass fiber cloth, only double-layer filtration of the filter bag body is formed, dust and impurities subjected to secondary filtration can conveniently and rapidly fall down and are intensively accumulated through gaps between the supporting net bodies, follow-up cleaning is facilitated, the dust removal filter bag can be conveniently arranged on a dust remover cage frame in a sleeving mode, and a rotary locking block can be rotated through a simple tool; and through combined operation of the fixed lock teeth and the sealing cover, the rotary lock block is clamped and fixed, the lock strips are prevented from rebounding, meanwhile, the lock catches are protected, and the lock catches are prevented from being eroded and corroded by dust and impurities.

Description

technical field [0001] The invention relates to the technical field of filter devices, in particular to a dust filter bag based on non-alkali expanded glass fiber cloth. Background technique [0002] Dust removal filter bag is a kind of high-efficiency dust removal filter material. The dust removal filter bag is made of polyester staple fiber, pps fiber, pp polypropylene, aramid fiber, aramid fiber, etc., and its service life is generally 2-4 years. Excellent air permeability, high dust collection rate, easy to clean dust, dust removal efficiency can reach 98.99%, and has a good removal of PM2.5. At present, the internal space of existing bag-type dust collectors is relatively small, and the installation of traditional dust filter bags requires external fasteners to assist in fixing, which not only presents installation difficulties, but also causes parts to easily fall into the equipment during subsequent disassembly. Therefore, we improve this and propose a dust filter ba...
