Abstract

The utility model relates to a rotary cloth bag dust remover which is capable of vibrating and blowing back, comprising a blower, a vertical vibrating rotary device, an electromotor, a cylinder, a dust collecting funnel and a dust discharge valve. The utility model is characterized in that the vertical vibrating rotary device is butted with a fixed idler disk via the movable arms of three idlers, the movable arms of three idlers can rotate on the fixed idler disk in order to connect and drive vibrating arms via a movable air pipe, and extending joints can seal with a dust suction cloth bag accurately for blowing dust in the cloth bag. The utility model having reasonable design, simple structure and high work efficiency is ideal equipment for cement manufacture industry.

Description

Bag dust collector

The utility model belongs to cement manufacturing dust falling device device, especially can shake the deduster of playing blowback revolution cloth bag up and down.

At present, the blowback swinging sack cleaner that known domestic and international manufacturing cement industry uses, a cloth bag is blown afloat, and the cloth bag of its both sides still is in negative pressure state, this moment, just the dust under blowback was absorbed by the cloth bag of work both sides again, cause the both sides cloth bag easily to stop up, only blow a cloth bag, make deduster improve working efficiency for solving each revolution.

The purpose of this utility model provides a kind of shake up and down and makes blowback revolution sack cleaner, it can not only turn round at every turn and only blow a cloth bag, and cloth bag is all shut automatically before and after its adjacent both sides, and the dust that blowback is got off all falls among the deduster, and the dedusting operating efficiency can improve more than 10%.

The purpose of this utility model is achieved in that from top to bottom hair-dryer, vertical shake return rotary device, motor, cylindrical shell, flue-dust retainer and ash-valve and form.It is characterized in that vertical shake returns rotary device and connect three carrying roller lever arms by bearing box, bear the synchromesh gear drive and do the circumference rotation, three carrying roller lever arms rely on spline to slide, move up and down, three carrying roller lever arms dock with fixing carrying roller dish, and carrying roller is housed all, three carrying roller lever arms are fixedly rotating on the carrying roller dish, the shake of ceaselessly sliding is up and down beaten, and fixedly the carrying roller dish is fixed on the cylindrical shell top cover, below be provided with the cone bearing box, inner ring cooperates rotation with spline, three carrying roller lever arm lower ends and movable airduct join, and and shake beat spring be housed between the arm, shake to beat and be equipped with movable airduct support roller under the arm, the right side is three and stretches out joint, have only middle one to open mouth with the cloth bag banjo fixing butt jointing, other two is airtight, and control pulsation air discharge cook is housed on the inverted ventilation pipe.

Owing to adopt technique scheme, can extensively implement making cement industry, solved that positive and negative pressure causes the obstruction of dust suction cloth bag in the deduster, ineffective big problem, this machine is reasonable in design, and is simple in structure.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 shakes the unitary construction figure that makes blowback revolution sack cleaner up and down.

Fig. 2 shakes the vertical shake of making blowback revolution sack cleaner up and down to return the rotary device profile.

Fig. 3 shakes dozen blowback revolution sack cleaner shake up and down to beat the cutaway view that arm stretches out joint and dust suction cloth bag.

Among the figure 1. back blowing machines, 2. inverted ventilation pipes 3. vertically shake slewing equipment 4. splines 5. bearing boxs 6. cone bearing boxes 7. 3 carrying roller lever arms 8. fixedly carrying roller dish 9. synchromesh gears 10. movable wind ducts 11. springs 12. shake arm 13. motor 14. movable wind duct support rollers 15. and stretch out joint 16. air inlets 17. cloth bags 18. cyclone types and advance mouth 19. cylindrical shells 20. ash-valves 21. flue-dust retainers 22. exhaust openings 23. pulsation air discharge cooks 24. carrying rollers 25. carrying rollers

The framework of deduster is in order by back blowing machine 1 in Fig. 1, Fig. 2), motor (13), cyclone type advance mouth (18), cylindrical shell (19), flue-dust retainer (21), ash-valve (20) and exhaust opening (22) and form.Its concrete enforcement structure is that the inverted ventilation in the inverted ventilation pipe (2) is controlled through pulsation air discharge cook (23), returning device (3) with vertical shake is connected, it is to do the circumference rotation by the three carrying roller lever arms (7) that synchromesh gear (9) drives on the upper bearing (metal) box (5) that rotary device is returned in vertical shake, move up and down by spline (4) slip lever arm, lever arm (7) links to each other with movable airduct (10), spring (11) is contained in movable airduct (10) and shake is beaten in the middle of the arm (12), three carrying roller lever arms (7) dock with fixing carrying roller dish (8), arm all respectively is equipped with carrying roller (24) with dish, (25), lever arm (7) rotates on carrying roller dish (8), driving shake beats arm (12) and ceaselessly slides to shake up and down and beat, fixedly carrying roller dish (8) is fixed on the top cover of cylindrical shell (19), the carrying roller dish has cone bearing box (16), its inner ring supports the rotation of spline (4), it is fitted together with carrying roller dish (8), and inner ring rotates together with three carrying roller lever arms (7).

What Fig. 3 described is that arm (2) and dust suction cloth bag (17) are played in shake, shake is beaten arm (2) lower end movable airduct support roller (14) is housed, its right side has three and stretches out joint (15), three are stretched out and have only an air inlet (16) in the joint (15), shut for other two, dust suction cloth bag (17) is that evenly row is routine in cylindrical shell (19), only provides one group among the figure.

It is such shaking the course of work of making blowback revolution sack cleaner up and down: inverted ventilation is controlled by pulse air draft switch through the inverted ventilation pipe, when inverted ventilation is blown into switch opens, stretch out joint and just in time insert cloth bag this moment, three are stretched out joint and have only an air intake, adjacent two block cloth bag, dust promptly falls into flue-dust retainer, at this moment three carrying roller lever arms and fixedly the carrying roller in the carrying roller dish stagger, otherwise pulse air draft switch cuts out, and shake is beaten arm and driven and to stretch out joint and lift, and the wait inverted ventilation is blown into, at this moment, three carrying roller lever arms and fixedly the carrying roller in the carrying roller dish oppose, periodic duty in this way reaches desirable dust removing effects.
