A dust filter bag

Abstract

The invention relates to a dust-removing filter bag. According to the invention, the lower end of a mounting plate is provided with a fixed drum; two through holes are arranged on the mounting plate;the upper ends of the through holes are provided with sealing assemblies; the lower ends of two through holes are respectively provided with a first cage frame and a second cage frame which are arranged on the mounting plate; the interiors of the first cage frame and the second cage frame are respectively provided with a first filter bag body and a second filter bag body; the lower ends of the first cage frame and the second cage frame are respectively connected with a fixed iron block through a spring; an electromagnet is arranged below each fixed iron block; each electromagnet is arranged ona telescopic rod; the inner walls of two sides of the fixed drum are respectively provided with a compression cylinder; compression plates corresponding to the first cage frame and the second cage frame are respectively arranged at the front ends of two compression cylinders; a slidable supporting block is arranged between two telescopic rods; two clamping cylinders are symmetrically arranged onthe supporting block; and the front end of each clamping cylinder is provided with a clamping plate. The dust-removing filter bag provided by the invention can rapidly and effectively fix the positions of two filter bag bodies firmly, is convenient for installation and maintenance, and can adjust the opening size of the filter bag bodies at the same time.

Description

technical field [0001] The invention belongs to the technical field of dust removal filter bags, in particular to a dust removal filter bag. Background technique [0002] The dust filter bag is a kind of high-efficiency dust filter material, which has good ventilation performance, high dust removal efficiency, and has certain acid, alkali and heat resistance. [0003] With the rapid development of society and the advancement of science and technology, the demand for dust filter bags is increasing. At present, some dust filter bags are equipped with multiple filter bags, which can improve the efficiency of dust removal, but in such a dust filter bag device containing multiple filter bags, the positions of the two filter bags are not easy to fix. The position of the filter bag cannot be locked, which may lead to danger in the later stage. At the same time, the outlet size of the filter bag cannot be adjusted, which brings a lot of inconvenience to the actual use. Contents o...
