Abstract
The invention provides a filter bag fixing mechanism of a pulsed bag type dust remover, which has simple structure and can prolong the service life of filter bags and improve dust removing efficiency. The filter bag fixing mechanism comprises a fixing frame, combined cover-shaped nuts, gaskets and studs. The fixing frame is an oblong frame formed by welding profile steel and is installed on a nut cap at the top end of a row of cage frame, and a plurality of through holes are arranged around the fixing frame; and the studs are welded and fixed among pattern plate holes of a pattern plate, and the number and the positions of the studs correspond to the number and the positions of the through holes around the fixing frame. When the filter bag fixing mechanism is installed, the plurality of studs are firstly welded among the pattern plate holes of the pattern plate, the fixing frame provided with the through holes passes through the studs and then is installed on the nut cap at the top end of the cage frame, each stud is sheathed with one gasket, the combined cover-shaped nuts are screwed on the studs to apply pressure to the fixing frame so that the fixation of the cage frame and the relative rest of the filter bags are ensured; and the filter bag fixing mechanism avoids the mutual friction among the filter bags, prolongs the service life of the filter bags and simultaneously quickens the settlement of dust to improve dust removing efficiency and dust removing effect.
Description
Technical field
The present invention relates to a kind of filter bag fixed mechanism of suction type pulse bag type dust collector, particularly a kind of pulse bag type dust collector.
Background technology
Existing large-scale row spray pulse bag type dust collector is the negative pressure operation, adopts the outside filtering type filter type, i.e. filter bag bottom sealing, and upper opening shrinks in order to prevent filter bag in the course of the work, and cage is housed in filter bag, is suspended on the card through block; The sack of filter bag adopts the snap ring interlocking in the card hole.The duty of pulse bag type dust collector is divided into filters and two kinds of deashings; When deduster when filtering, dusty gas gets into the air channel of deduster by the deduster air inlet, equal wind apparatus is assigned to each filter chamber equably with gas through the air channel; Filter through filter bag from bottom to top then; Dust is delayed at the outer surface of filter bag, and clean gas is after filtering discharged to get into by filter bag opening and discharged after air-purifying chamber compiles, and accomplishes the filter process of dusty gas.When the dust layer thickness on filter bag surface acquires a certain degree; Must carry out deashing to guarantee the required gas permeability of filter bag continuous firing to filter bag; Pulse jet mechanism ejection this moment high pressure draught; Filter bag is expanded, the dust on filter bag surface is shaken off to the ash bucket of below, realize deashing operation filter bag.
In the filtration of sack cleaner, deashing process, because the irregular of air-flow flowed, cause acutely rocking of cage and filter bag, particularly the bottom amplitude is bigger, causes the phase mutual friction between filter bag, has reduced service life; Especially when deduster filters, owing to filter bag receives suction function, be in to receive flat state, add the effect of ascending air, cage tends to be lifted, and has strengthened the folding amplitude of filter bag, has reduced service life, influences dust removing effects.Simultaneously, constantly rocking of filter bag and cage also caused the sedimentation that is difficult to of dust; Prolonged the sedimentation time of dust, the dust particularly thin for particle, that viscosity is strong causes second adsorption easily; Strengthen the load of deduster, influenced the normal operation of sack cleaner.
Summary of the invention
Technical problem to be solved by this invention is, to the deficiency of prior art, provide a kind of simple in structure, can prolong life of bag filter, improve the filter bag fixed mechanism of the pulse bag type dust collector of efficiency of dust collection.
The technical scheme that the present invention solves its technical problem is: comprise fixed mount, combined type acorn nut, packing ring and double-screw bolt.The rectangular frame of fixed mount for adopting shaped steel to be welded is placed on the block on row's cage top, and around fixed mount, having some through holes is long kidney-shaped hole; Stud welding is fixed between the card hole of card, and its number is corresponding with the through hole around the fixed mount with the position.During installation; Between the card hole of card, weld several double-screw bolts earlier; The fixed mount that will have through hole again passes on the block that double-screw bolt is placed in the cage top, and each double-screw bolt all overlaps upper gasket, and the combined type acorn nut is exerted pressure to fixed mount through on double-screw bolt, screwing; Thereby guaranteed the fixing of cage, also guaranteed the static relatively of filter bag.The use of combined type acorn nut has prevented that effectively dust from accumulating on the thread of double-screw bolt, produces wearing and tearing when avoiding dismantling, and damages thread, also makes staff's easy to disassemble and assemble when repair and maintenance.
The invention has the beneficial effects as follows: simple and reasonable, reduce cost of equipment maintenance, avoided the phase mutual friction between filter bag; Prolonged the service life of filter bag; Accelerate the sedimentation of dust simultaneously, improved efficiency of dust collection and dust removing effects, reduced the load of deduster; Energy-saving effect is obvious, is specially adapted to handle the dust that particle is thin, viscosity is strong.

Among the figure: 1 is that card, 2 is that filter bag fixed mechanism, 2-1 are that fixed mount, 2-1-1 are that through hole, 2-2 are that combined type acorn nut, 2-3 are that packing ring, 2-4 are that double-screw bolt, 3 is that cage, 4 is filter bag.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further explain.
Present embodiment comprises fixed mount 2-1, through hole 2-1-1, combined type acorn nut 2-2, packing ring 2-3 and double-screw bolt 2-4.The rectangular frame of fixed mount 2-1 for adopting shaped steel to be welded is placed on the block on row's cage 3 tops, and around fixed mount 2-1, having some through hole 2-1-1 is long kidney-shaped hole; Double-screw bolt 2-4 is weldingly fixed between the card hole of card 1, and its number is corresponding with the through hole 2-1-1 around the fixed mount 2-1 with the position.During installation; Between the card hole of card 1, weld several double-screw bolts 2-4 earlier; The fixed mount 2-1 that will have through hole 2-1-1 again passes on the block that double-screw bolt 2-4 is placed in cage 3 tops, and each double-screw bolt 2-4 all overlaps upper gasket 2-3, and combined type acorn nut 2-2 exerts pressure to fixed mount 2-1 through on double-screw bolt 2-4, screwing; Thereby guaranteed the fixing of cage 3, also guaranteed the static relatively of filter bag 4.Cage 3 and filter bag 4 do not produce when filtration, deashing and rock like this, have avoided filter bag 4 because of the phase mutual friction damages, and have prolonged the service life of filter bag 4, help the sedimentation of dust simultaneously yet, have improved the operating efficiency of sack cleaner.
The use of combined type acorn nut 2-2 has prevented that effectively dust from accumulating on the thread of double-screw bolt 2-4, produces wearing and tearing when avoiding dismantling, and damages thread, also makes staff's easy to disassemble and assemble when repair and maintenance.
