Filter bag structure of dust collector

Abstract

The invention discloses a filter bag structure of a dust collector. The filter bag structure of the dust collector comprises a base; one end of the base is connected with a fixing head; an air-vent port is formed in the center of the fixing head; a bag cage is fixed at the bottom of the air-vent port; the periphery of the bag cage is connected with a filter bag main body; a filter bag head is integrally formed at one end of the filter bag main body; a rubber band is embedded inside the filter bag head; the rubber band is arranged in an annular groove in a sleeving manner; the annular groove isformed in the periphery of the fixing head; the outer side of the filter bag head is clamped and connected with a hoop; the inner side of the hoop is fixed with a clamping block corresponding to theannular groove; and the inner wall of the clamping block is fitted with a rubber pad; according to the invention, through the arranged hoop and a stainless steel clamping ring, the filter bag head andthe fixing head are fixed by the cooperation of the hoop and the annular groove, and the bottom end of the filter bag main body is matched and connected with the bag cage through the stainless steelclamping ring, so that the installation verticality of the filter bag is well ensured, the shaking and wear of the filter bag are effectively reduced, and the service life of the filter bag is prolonged.

Description

technical field [0001] The invention relates to the technical field of dust collector equipment, in particular to a filter bag structure of a dust collector. Background technique [0002] Bag-type dust removal equipment is suitable for the separation of dust from dust-containing gases in food, grain, medicine, building materials, chemicals and other industries. The material device is collected by the material collecting device and then discharged. The bag filter is a dry dust removal device suitable for capturing fine, dry, non-fibrous dust. The filter bag is a very important part of the bag dust collector. The filter cloth of the existing dust removal equipment is mainly staple fiber needle-punched non-woven fabric, and the raw material used is short fiber. The dust-containing gas is filtered by the filter function of the fiber fabric. When the dust-containing gas enters the bag filter, the dust with large particles and specific gravity will settle down due to the action ...

AI Technical Summary

Problems solved by technology

At present, the filter bags used in the bag filter are generally long, and there is no installation and fastening structure at the lower part, which is inconvenient to fix. After installation, the verticality of the filter bags cannot be guaranteed, and they are easy to tilt or even touch each other, especially when the flue gas is introduced. Under the action of air flow, the filter bag is easily worn, which greatly reduces its service life
