Flexible filter bag device of pulse dust collector

Abstract

The invention provides a flexible filter bag device of a pulse dust collector. The flexible filter bag device consists of a filter bag, an upper bushing ring, anti-flat rings, a hose, a back-over filter bag plate, a bundling rope, a tension spring, upper and lower hooks and a hanger, wherein the upper bushing ring is arranged to be a conical plug bushing ring; a semicircular arc clamp groove is arranged on the outer wall of the upper bushing ring; the outer circle of the upper end face of the upper bushing ring is larger than a pattern card hole, so as to tightly press a sealing ring of the filter bag; the anti-flat rings are arranged in the filter bag, and are fixedly arranged inside the filter bag according to a certain distance; the bundling rope is arranged at the lower end of the filter bag, and is bundled on the back-over lower filter bag plate; the grating type filter bag hanger is arranged at the upper end of a dust hopper; and the tension spring is fixedly arranged on the filter bag plate and the hanger by using the upper hook and the lower hook. The flexible filter bag device provided by the invention has the advantages of simple structure and easiness in manufacturing; the filter bag and the pattern card hole are in tight contact; no movement exists; the filter bag can be prevented from being damaged, and is convenient to replace; the service life of the filter bag is prolonged; and various defects of a cage type rigid framework can be overcome.

Description

Technical field: [0001] The invention relates to the technical field of filter bag devices for industrial dust collectors in environmental protection equipment, in particular to a flexible filter bag device for pulse dust collectors, which is mainly used in various pulse bag dust collectors. Background technique: [0002] The pulse bag filter adopts the negative pressure external filter type, the filter bag diameter is 130~160mm, the length is 2.45~6m, and the filter bag skeleton needs to be set inside the filter bag. At present, the cage-type steel frame is mostly used in China, which is welded by φ4mm steel wire. The cage-type steel frame has the following defects: [0003] Welding requires special equipment, many solder joints, heavy workload and high cost. [0004] Large aspect ratio, easy to deform during transportation, loading and unloading, installation, and bag changing, welding points are easy to break, and transportation costs are high. [0005] The dust collect...

AI Technical Summary

Problems solved by technology

[0007] Collisions between filter bags, especially the bottom of the filter bags, are easy to occur and damage the filter bags. As long as one filter bag is damaged, the standard discharge cannot be achieved

Due to the corrosion of the bag cage, the adhesion between the filter bag and the bag cage is caused, which makes it difficult to change the bag
