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...

Problems solved by technology

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 precision requirement is high and the processing is difficult. During the production, a precision automatic cutting machine is required to cut out the required fixing holes on the entire steel plate. However, the general hand-held cutter is easy to deform and cannot meet the precision requirements at all. Not only the investment in processing equipment is large, but also time-consuming and troublesome, and the waste of cutting materials is serious

The second is that the fixing of the bag mouth is cumbersome, time-consuming and labor-intensive, and the reliability is poor. Although there are many fixing methods, there are problems in this respect: if the filter bag seat or short tube structure is used, it is necessary to use a bag to tie the head, tie hoop, tie rope, etc. Hole by hole is tied by hand, which is time-consuming and labor-intensive, and the efficiency is low

The third is to use a flower plate to fix the filter bag. Only one filter bag can be fixed in each hole. The filter bag and the filter bag are separated into independent parts. The effective utilization rate of the dust removal box is low, a waste of resources, and it is difficult to adapt to the development trend.
