The utility model is characterized in that the main body of an inner cylinder is of cylinder shape or square body shape, the main body of the outer cylinder is of cylinder shape or square body shape, the middle part of the main body of the outer cylinder is of inverted four-arris table shape or cone shape, and the port on the lower part of the outer cylinder is connected with apull rod, a withdrawal stopping spanner, a fixing supporting plate, a spring, a movable supporting plate and other parts which are formed into a box opening bracing pulling part. One part of the main body of the inner cylinder is in the main body of the outer cylinder, the bottom of the inner cylinder is connected with a balance type air locking device, and an automatically dust expelling part is composed of an upper close cover, a lower close cover, a counterbalance, etc.

Description

Dry type dust collecting apparatus

The utility model relates to collects industry and heating boiler (or kiln) flue dust dry type assembling sphere, is specially a kind of dry type dust collecting.

Boiler or kiln are in operation and all are furnished with deduster miscellaneous, and they all must be in the state of not leaking out when operation, otherwise will reduce the efficiency of dust collection of deduster.So the dust-exhausting port of deduster is equipped with movable or the fastening-type dust exhaust.But, in service in real work, because this class dust exhaust often damages, or be subjected to the narrow and small restriction in deduster place of living in, be not easy to transport flue dust, or because of sanitary condition relatively poor, operating personnel are deashing in time, cause the locked or uncovered operation of leaking out of dust exhaust, thus deduster can not be on request regularly or remove flue dust automatically, efficiency of dust collection reduces or is ineffective fully.Moreover, from the flue dust that deduster gets off, stack everywhere, very easily produce secondary smoke and pollute.

The purpose of this utility model is to provide a kind of working environment that makes to improve greatly, can automatically the flue dust of collecting be installed in the container of dirt, eliminates reentrainment of dust and pollutes, and reaches a kind of dry type dust collecting of protection atmospheric environment.

The purpose of this utility model is achieved in that the inner core body is the cylinder bodily form or the square bodily form, the urceolus body is the cylinder bodily form or the square bodily form, the middle part of urceolus body is shape of falling the truncated rectangular pyramids or taper shape, be connected with pull bar, retaining spanner in lower port, fixedly fagging, spring, Movable fagging etc. constitute the bag opening support pull portion, one one of the inner core body in the urceolus body, the bottom is connected with the balanced type flapper, and upper cover, capping down, counterweight etc. constitute automatic dust discharge part.Side at the urceolus body has a gland, and several shallow slots are arranged on the pull bar, and the retaining spanner can slide front and back in groove.

Advantage of the present utility model is: simple in structure, with low cost, eliminate secondary pollution, protection atmospheric environment, adorn dirt automatically.

Fig. 1 is the utility model structural principle generalized section;

Fig. 2 is the utility model structural principle A-A generalized section;

Fig. 3 is the utility model structural principle B-B generalized section.

Capping under 1-Movable fagging, 2-pull bar, 3-retaining spanner, 4-balanced type flapper, 5-urceolus body, 6-gland, 7-bearing pin, 8-inner core body, 9-peep hole, 10-ring flange, 11-upper cover, the 12-, 13-nut, 14-spring, 15-be fagging, 16-nut, 17-round iron, 18-counterweight, 19-shallow slot fixedly.

Below in conjunction with accompanying drawing in detail the utility model most preferred embodiment is described in detail:

Inner core body top is welded with the circular flange dish, so that be connected with boiler or kiln deduster body, inner core body lower port is welded with upper cover, following capping is welded on the round iron of balanced type flapper, by adjusting the nut of balanced type flapper afterbody, and the counterweight of change counterweight, thereby adjust and control inner core body in what of dust quantity, when the dust quantity in the inner core body acquires a certain degree, the balanced action of flapper is destroyed, automatic and the upper cover unlatching of following capping, flue dust is discharged from the inner core body, and enters the urceolus body.Can observe the dust discharge situation whenever and wherever possible by peep hole, so that corresponding adjustment dust-exhausting quantity.There is a gland urceolus body side, behind the unlatching gland, can keep in repair and adjust dust-exhausting quantity to counterweight, flapper by this hole.Pull bar is fixed on two short sides of this dust-exhausting port, and there are several shallow slots side, pull bar right side, and the retaining spanner enters or withdraws from the shallow slot, can control the length that pull bar is pulled out.Movable fagging is fixed on the pull bar bottom, and fixedly fagging is welded on urceolus body dust-exhausting port, its excess-three face barrel lower limb, and spring housing is fixed spring and pull bar by nut in the left side of pull bar, and can carry out the elastic force adjustment to spring by nut.When using the bag opening support drawing device, the major part of the sack of the fibrage bag that will purchase in advance earlier is mounted on fixedly on the fagging, extract the retaining spanner then, pull bar is pulled out, simultaneously, another fraction of sack is mounted on the Movable fagging on the pull bar, in the time fixing sack, dial back the retaining spanner, this moment, the pull bar respective fixation was motionless, when inner core body balanced type flapper comes into operation dust discharge, the dirt of discharging fume just enters sack by urceolus body bottom ash discharging hole, when sack is filled the dirt ash, by hand sack is tightened, then unified the concentrating of bag transported.
