Description

The Filter bag device of pulse dust collector
Technical field
The invention belongs to technical field of dust removal equipment more particularly to a kind of Filter bag devices of pulse dust collector.
Background technology
Pulse bag type dust collector, through being widely used both at home and abroad, has been continuously improved, in purification dust-laden since the fifties come out It achieves in terms of gas and develops on a large scale very much, since ash-clearing technology is advanced, air cloth ratio increases substantially, therefore air quantity is big, accounts for handling The features such as ground area is small, purification efficiency is high, reliable operation, simple in structure, a little repair.The country mostly uses cage rigidity bone at present Frame is applied in combination with flexible bag, but uses cage steel frame, has the following defects:Welding needs special equipment, solder joint is more, It is heavy workload, of high cost, and transport, load and unload, installing, to change bag cumbersome time-consuming.Filter bag inside is carried out using blowning installation When air blowing deashing, fitting compared with being with skeleton due to filter bag, filter bag not will produce larger deformation, just with back draught The dust being adhered on filter bag is blown outward, ash-removal effect is limited.
Invention content
The purpose of the present invention is to provide a kind of Filter bag devices of pulse dust collector, in utilization blowing device to filter bag ash removal When filter bag can be made back and forth to shake, while clappers also can back and forth pat filter bag, ash-removal effect is good.
In order to achieve the above object, base case of the invention is:The Filter bag device of pulse dust collector, including filter bag, filter Shaft is equipped in bag, shaft is rotatably connected in deduster, and shaft is equipped with flabellum, and shaft is equipped with several convex successively from the bottom to top Wheel, the direction of the lug boss of two neighboring cam along cam curved surface on the contrary, offer sliding slot, equipped with several motion bars in filter bag Group, each motion bar group include two horizontally disposed motion bars, and two motion bars engage and slide close to one end of shaft It is connected in sliding slot, two one end of motion bar far from shaft are fixedly connected with filter bag, are slidably connected on two motion bars There are vertically arranged clappers, the lug boss and cylindrical portion of cam to be respectively equipped with the first magnet and the second magnet, two clappers are close The side of shaft is equipped with third magnet, and magnetic pole of first magnet far from shaft one end is with third magnet close to the magnetic of shaft one end Extremely identical, magnetic pole of magnetic pole of second magnet far from shaft one end with third magnet close to shaft one end is opposite.
The operation principle of this base case is:Shaft and several motion bars constitute skeleton, make filter bag in dust filtering process In will not be flat.When using blowing device to filter bag ash removal, there is a large amount of air-flow to enter inside filter bag, air-flow will enter in filter bag Portion, then air-flow the dust being adhered on filter bag outer wall will be blown off.Simultaneously because shaft is equipped with flabellum, therefore when air-flow is blown When into filter bag, air-flow can apply flabellum one power for making it rotate, and shaft is rotatably connected in deduster, therefore flabellum Shaft can be driven to rotate, since shaft is equipped with several cams, so cam can also be rotated with shaft.And the curved surface of cam It is equipped with sliding slot, motion bar is close to the engaging of one end of shaft and is slidably connected in sliding slot, so cam can drive work when rotating Lever moves back and forth in the horizontal direction, since the one end of motion bar far from shaft is fixedly connected on filter bag, so motion bar is past Filter bag can be driven back and forth to shake when moving again, to make filter bag generate deformation, be adhered to the dust on filter bag lateral wall in filter bag Shaken off under the action of shake and deformation, and due to the direction of the lug boss of two neighboring cam on the contrary, so neighbouring Motion bar group motion state meeting on the contrary, be bent to filter bag, keep the deformation of filter bag maximum, while the shake effect of filter bag It is best.Since the lug boss of cam is equipped with the first magnet, two clappers are equipped with third magnet, the first magnetic close to the side of shaft Magnetic pole of magnetic pole of the body far from shaft one end with third magnet close to shaft one end is identical, so in cam rotation process, when When lug boss is towards motion bar, the first magnet can generate repulsive force to third magnet, to make clappers to close to filter bag side wall Direction moves, and finally clappers are clapped to filter bag side wall, realize the beating to filter bag, to which clappers can pat the dust on filter bag Go down;And the cylindrical portion of cam is equipped with the second magnet, magnetic pole of second magnet far from shaft one end is with third magnet close to shaft The magnetic pole of one end is on the contrary, so when cylindrical portion is towards when having the final say, and clappers can be moved to the direction close to shaft, and it is next to make clappers Secondary beating is prepared.
The advantageous effect of this base case is:This programme is used as skeleton using motion bar and shaft, compared to fixation For the rigid backbone of formula, the skeleton of this programme is easy for installation, dismounting facility;This programme is in utilization air-jet device to filter bag ash removal When, filter bag can be driven to generate deformation and reciprocal shake by shaft, cam and motion bar, be conducive to carry out dust on filter bag Cleaning, cleaning efficiency are high, ash-removal effect, and have the final say in deashing process and also can back and forth pat filter bag, can be further Raising cleaning efficiency, and pat the stronger dust of adhesiveness can be cleaned up, cleaning effect is good.
Further, the upper surface of motion bar is inclined-plane, and inclined-plane is higher side close to one end of shaft, so set, Speed of the clappers close to filter bag can be improved, keeps the effect that clappers pat filter bag more preferable, ash-removal effect is more preferable.
Further, the upper end of clappers is tilted to close to one end of shaft, is arranged such so that clappers pat filter bag side wall When, clappers are more bonded with filter bag side wall, and it is good to clap grey effect.
Further, filter bag side wall is equipped with two sections elastic corrugated section, and bellows segment generates elastic oscillation, ash-removal effect when deashing It is good.
Further, anti-corrosion layer is coated on filter bag outer surface, the anti-corrosion layer is polytetrafluorethylecoatings coatings, can be kept away The corrosive goods confrontation filter bag exempted from flue gas causes to damage.
Description of the drawings
Fig. 1 is the sectional view of the Filter bag device embodiment of pulse dust collector of the present invention;
Fig. 2 is the enlarged drawing at A in Fig. 1.
Specific implementation mode
Below by specific implementation mode, the present invention is described in further detail:
