Abstract
The utility model provides an automatically sealed and circulative electrostatic powder-spraying apparatus. A suit of automatic sieving machine and powder reclamation pneumatic delivery device to send back a powder supply device is arranged between a vortex separating powder retriever which can reclaim the powder and the powder supply device so as to realize automatically sealed and circulative use. The utility model has the advantages of high work efficiency and low cost, and the quality of the sprayed powder is ensured.
Description
The utility model relates to a kind of equipment that is used for electrostatic powder spraying.
Existing electrostatic powder spraying equipment is made up of electrical control gear, powder feeder, electrostatic high-pressure dusting device, powder spraying chamber, suspension workpiece carrier chain, cyclonic separation Powder Recovery device, powder collecting bucket, cloth bag filtering powder retracting device, electronic sieving machine, air compressor, oil water separator etc.The electrostatic high-pressure dusting device is by electrostatic high-pressure generator, and podwer gun and travel mechanism thereof form.This electrostatic powder spraying equipment can only be accomplished semi-automation, because the powder that reclaims through cyclonic separation Powder Recovery device can only be stored in the powder collecting bucket, reuses through the artificial powder feeder that adds after also will sieving in addition again.In this process, the easy contaminated environment of powder, make moist and other impurity is sneaked into, when this powder is reused, influence by the coating quality of spraying workpiece.
In view of there being the problems referred to above, the design's task provide a kind of recovery powder through the Automatic sieve powder after, directly be conveyed into powder feeder from movable sealing circulation electrostatic powder spraying equipment.
The design's task be achieved in that in the static that between the bottom of cyclonic separation Powder Recovery device and powder feeder, is provided with a ground connection and automatically sieving machine and one by the recovery powder Pneumatic conveyer of air nozzle to duff pipe mouth gas jet.The powder that the bottom of cyclonic separation Powder Recovery device is reclaimed get off, through in the static and after sieving automatically, principle according to the venturi aspirator, be provided with and reclaim the powder Pneumatic conveyer, be about to compressed air from air nozzle when the duff pipe mouth sprays, local space in cyclonic separation Powder Recovery device bottom---the periphery of air-flow produces negative pressure between air nozzle and the duff pipe mouth, powder after recovery sieved along with compressed air stream together to the diffluence of duff pipe mouth, become powder gas admixture, the new powder that enters powder feeder and storage through recovery powder carrier pipe sprays again.
The utility model is owing to used recovery powder Pneumatic conveyer, powder through the recovery of cyclonic separation Powder Recovery device, just do not need a dead lift to sieve and add powder feeder again, and in static and after sieving machine sieves automatically, directly sent into powder feeder by Pneumatic conveyer, realization loops back to receive from movable sealing and uses, and this had both improved Powder Recovery rate and operating efficiency, has guaranteed the quality of spraying again.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an electrical control gear schematic diagram of the present utility model.
Fig. 3 is a Powder Recovery Pneumatic conveyer schematic sectional view.
With reference to Fig. 1, Fig. 2 and Fig. 3, with the powder spraying chamber 2 that sheet metal is made, it is indoor to be to hang workpiece carrier chain 5 by the top, and the portability workpiece passes through with certain linear velocity in powder spraying chamber 2, sprays automatically.Import, the outlet 16 of spraying workpiece are arranged at the two ends of powder spraying chamber 2.In the both sides of powder spraying chamber 2 electrostatic high-pressure spray equipment 3 is housed, it is made up of electrostatic high-pressure generator 13, the electrostatic high-pressure podwer gun 14 that is contained in powder spraying chamber 2 both sides and travel mechanism 15 thereof.Electrostatic high-pressure generator 13 is the employing combining form, and its maximum output voltage is 100KV, and has overvoltage protection and constant current device automatically.Electrostatic high-pressure produces electrostatic field by the head that cable is added to podwer gun 14.Electrostatic high-pressure podwer gun 14 is made up of rifle head, the body of a gun, air diffuser, pulverized coal feed pipe etc.For reaching desirable electrostatic spraying effect and quality, it must possess characteristics such as withstand voltage, that powder delivery even, maintenance is esy to use, safe and reliable.The travel mechanism 15 of electrostatic high-pressure podwer gun 14 is the electromechanical structure form, and move mode divides swing and parallel movable.The powder of electrostatic high-pressure spray gun 14 is supplied with by powder feeder 4 through pulverized coal feed pipe.The clean dried compressed air of its power source for filtering through oil water separator 8.Compressed air is produced by air compressor 22, the powder of powder feeder 4 is the fluid bed state, during use, regulate compressed air pressure by pressure regulator valve, make the powder fluidisation, its pressure is between 0.2～0.5 atmospheric pressure, and powder is a principle normally to stir, not overflow, and controls powder outlet quantity and fluidized powder concentration simultaneously.
Powder spraying chamber 2 is connected with powder recovering device, generally all adopts secondary recovery, and the first order is a cyclonic separation Powder Recovery device 6, and the second level is dynamo-electric rapping formula cloth bag filtering powder recover 7.Under normal operative condition, because centrifugal fan 17 causes certain negative pressure, under the effect of negative pressure, be not adsorbed on the suspended powder of surface of the work in the powder spraying chamber 2, directly sucked powder recovery system, do not escape thereby reach powder, free from environmental pollution, realize reclaiming the purpose that re-uses.After the gas of band powder enters cyclonic separation Powder Recovery device 6 with certain wind speed, because powder is under the centrifugation of inertia and gravity, overwhelming majority powder evenly been separated in the bottom of cyclonic separation Powder Recovery device 6, through in the static of ground connection and after sieving machine 9 sieves automatically, enter again and reclaim powder Pneumatic conveyer 12, sent back to powder feeder 4.Reclaiming the powder Pneumatic conveyer is made of flange 18, valve body 19, compressed-air atomizer 10, duff pipe 11 and duff pipe joint 20.The residue that is not recovered trace powder enters the second level dynamo-electric rapping formula cloth bag filtering powder recover 7 through the top exit 21 of cyclonic separation Powder Recovery device 6, and the pure air after the filtration gets final product emptying.
