Filter bag fixing mechanism for pulse-jet bag dust collector

Abstract

The invention discloses a filter bag fixing mechanism for a pulse-jet bag dust collector. The filter bag fixing mechanism comprises a pressing plate, wherein the pressing plate is movably connected toone end of the top of a pattern card by virtue of rivets; a groove is formed in the middle of the pattern card; a positioning head penetrates through the middle of the groove; an annular groove is formed in the top of the positioning head; a pressure block corresponding to the annular groove is welded at the bottom of the pressing plate; through holes are correspondingly formed between inner holes of the pressure block; a bag cage is arranged just under the through holes; a filter bag is connected to the periphery of the bag cage in a sleeving manner; the bag cage is fixedly connected to thebottom of the positioning head; a movable head is hinged to one end of the pressing plate; a clamping block is fixed on the inner side of the movable head; torsion springs are clamped on two sides ofthe groove. According to the arrangement of the pressing plate, the filter bag and the bag cage are fixed at the bottom of the positioning head, the pressure block at the bottom of the pressing plateis correspondingly clamped in the annular groove of the positioning head, and finally the pressing plate is locked above the pattern card by utilizing the matched fixation of the clamping block and the clamping groove, so that the stable effect during filter bag fixation is improved.

Description

technical field [0001] The invention relates to the technical field of dust collector equipment, in particular to a filter bag fixing mechanism for pulse bag dust collectors. Background technique [0002] The working state of the pulse bag filter is divided into filtering and dust cleaning. When the dust collector is filtering, the dust-laden gas enters the air duct of the dust collector from the air inlet of the dust collector, and the gas is evenly distributed by the air duct uniform air device. Distributed to each filter chamber, and then filtered through the filter bag from bottom to top, the dust is trapped on the outer surface of the filter bag, and the filtered clean gas is discharged from the filter bag mouth into the clean air chamber and then discharged to complete the dusty gas the filtering process. During the filtering and dust cleaning process of the bag filter, due to the irregular flow of the air flow, the cage and the filter bag shake violently, especially ...

AI Technical Summary

Problems solved by technology

During the filtering and dust cleaning process of the bag filter, due to the irregular flow of the air flow, the cage and the filter bag shake violently, especially the lower part is larger, causing mutual friction between the filter bags, especially in the dust collector. When filtering, due to the negative pressure of the filter bag, it is in a deflated state, coupled with the effect of the updraft, the cage is often lifted, which increases the folding range of the filter bag, reduces the service life, and affects the dust removal effect

At the same time, the continuous shaking of the filter bag and the cage frame also makes it difficult for the dust to settle, prolonging the settling time of the dust, especially for the dust with fine particles and strong viscosity, it is easy to cause secondary adsorption and increase the load of the dust collector , affecting the normal operation of the bag filter
