Inner-filtering bag-type deduster

Abstract

An inner-filtering bag-type deduster comprises a dedusting box, and a filtering bag and fixing components thereof which are arranged in the inner cavity of the dedusting box, wherein the fixing components comprise a bag mouth fixing framework and a convex insert matched with the bag mouth fixing framework and used for fixing the filtering bag mouth; four sides of the bag mouth fixing framework arefixed on the inner wall of the dedusting box in a sealed manner; a plurality of lines of bag mouth receiving through grooves are cut in the middle of the bag mouth fixing framework; the filtering bagis a connected bag with serial bag structure, and upper filter drums of the connected bag are connected or separated; and the lower part of the connected bag is a public bag mouth, and the edge of the public bag mouth is pressed by the convex insert so as to be clamped on the sides and the lower plane of edges of the bag mouth receiving through grooves; and the convex insert and the bag mouth fixing framework are coupled to form an integral body. The manufacturing of the inner-filtering bag-type deduster is simple and convenient without the use of high-precise equipment, and especially, the processing of the connected bag is simpler, thus not only saving materials, and reducing manufacturing cost, but also reducing labor intensity of workers.

Description

【Technical field】

[0001] The invention relates to a bag dust collector, in particular to a filter bag fixing structure of an inner filter bag dust collector. 【Background technique】

[0002] The structure of the inner filter bag filter usually includes a dust removal box formed by connecting the upper, middle and lower boxes through flanges, and a flower plate, filter bag and its accessories located in the inner cavity of the dust removal box. The lower part of the inner cavity is used to fix the opening of the filter bag; the accessories include fixing parts to assist in fixing the opening of the filter bag to the hole of the flower plate, etc. With the continuous development of science and technology, the structure of the bag filter has also changed a lot, but the structure of using flower plates to fix the bag mouth of the filter bag has not changed, which has become a bottleneck restricting the development of this industry: one is the production of flower plates The prec...
