Abstract
The utility model relates to a kind of blackwash sprayers for casting, including tee tube, control switch, jet pipe, feed pipe, blast pipe, tee tube top exit is fixedly connected by control switch with jet pipe, and tee tube bottom inlet is fixedly connected with blast pipe, and centre entrance is fixedly connected with feed pipe；The jet pipe internal diameter is 12-16mm.Advantage is: overall structure is simple, solves the problems such as unstable existing spray gun pressure, spray nozzle clogging rapid wear；Each component is made of metal tube, bearing capacity is strong, it can adapt to the pressure of the compressed air of pipeline, meanwhile, under big pressure environment, and jet pipe uses internal diameter 12-16mm, it is not easy to plug, coating can be enable easily to penetrate into sand core surface layer, keep dope layer consistency high, surface quality of continuous castings is improved, solves the non-uniform status of casting sand mold brushing paint layer.
Description
Technical field
The utility model belong to cast paint spraying technology field more particularly to a kind of blackwash sprayer for casting.
Background technique
It is higher and higher to the castings desire of casting industry with being growing more intense for market competition, not only to the inherence of casting
Quality requirement flaw detection, and the surface quality requirements of casting are also increasingly promoted.Especially cast steel company is Thyssen gram captive
The In Mine Crusher shell of uncle's production, the requirement to spray quality are even more to have risen to a new height, casting industry
Casting quality require it is further harsh.For a long time, since casting scene type process is handwork, casting is seriously constrained
Quality, therefore surface quality of continuous castings annoyings always Foundry Production.Traditional foundry facing painting way far can not expire
Sufficient Foundry Production.And then sprayed coating is carried out to casting sand mold using spray gun, but existing spray gun serious wear, the every two moon just need
New spray gun is purchased, production cost is higher.Study carefully its source of damage, mainly nozzle is easily stifled, due to coating particles mainly
Larger, spray gun is easily stifled, and compressed gas used in scene, by pipeline, air pressure is larger, therefore causes nozzle rapid wear, while
The phenomenon that can cause spraying uneven in spraying process.
Summary of the invention
In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a kind of blackwash sprayer for casting, solutions
Certainly existing spray gun is easily blocked when spraying cast paint, or even the problem of damage；Coating is set easily to penetrate into sand core surface layer,
Dope layer consistency is improved, casting technique requirement is reached.
To achieve the above object, the utility model is achieved through the following technical solutions:
A kind of blackwash sprayer for casting, including tee tube, control switch, jet pipe, feed pipe, blast pipe, tee tube
Top exit is fixedly connected by control switch with jet pipe, and tee tube bottom inlet is fixedly connected with blast pipe, centre entrance with
Feed pipe is fixedly connected；The jet pipe internal diameter is 12-16mm.
The blast pipe, feed pipe, jet pipe are copper pipe.
The tee tube is to be threadedly coupled with control switch input end, feed pipe, blast pipe, jet pipe and control switch
Outlet end is threadedly coupled.
Angle between the blast pipe and feed pipe is 75 °~90 °.
Compared with prior art, the utility model has the beneficial effects that
Blackwash sprayer overall structure for casting is simple, solves existing spray gun pressure shakiness, spray nozzle clogging rapid wear etc.
Problem；Each component is made of metal tube, and bearing capacity is strong, can adapt to the pressure of the compressed air of pipeline, meanwhile,
Under big pressure environment, and jet pipe uses internal diameter 12-16mm, is not easy to plug, coating can be enable easily to penetrate into sand core surface layer, make to apply
Bed of material consistency is high, improves surface quality of continuous castings, solves the non-uniform status of casting sand mold brushing paint layer.Blackwash sprayer is each
It is all made of threaded connection between component, is conveniently replaced each component, reduces production cost.Blackwash sprayer effectively reduces cast steel
The generation of the casting flaws such as part scab and sand holes has saved coating dosage to reduce casting finish rehabilitation expense, reduces casting
Part cost input.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1- tee tube 2- control switch 3- jet pipe 4- blast pipe 5- feed pipe.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings of the specification, it should be noted that the utility model
Implement embodiment not limited to the following.
See Fig. 1, a kind of blackwash sprayer for casting, including tee tube 1, control switch 2, jet pipe 3, feed pipe 5, air inlet
Pipe 4,1 top exit of tee tube are fixedly connected by control switch 2 with jet pipe 3, and 1 bottom inlet of tee tube and blast pipe 4 are fixed
Connection, centre entrance are fixedly connected with feed pipe 5；3 internal diameter of jet pipe is 12-16mm；Live use isSpray
3 length of pipe is 25mm.
Wherein, blast pipe, feed pipe, jet pipe 3 are copper pipe, i.e., all components are rigid element, the pressure that can be born
It is larger.Tee tube 1 is to be threadedly coupled with 2 input end of control switch, feed pipe 5, blast pipe 4, and jet pipe 3 goes out with control switch 2
Mouth end is threadedly coupled, and can be convenient for daily maintenance, is conveniently replaceable components.Blast pipe 4 is connect by hose with compressed air pipe,
The flexible use of blackwash sprayer can be facilitated；Feed pipe 5 is connect by hose with paint can, facilitates paint can be placed on operator attached
Closely, convenient for spraying.Angle between blast pipe 4 and feed pipe 5 is α, α=75 °~90 °.
The utility model solves the problems such as existing spray gun such as pressure instability, spraying blockage rapid wear.Since this is practical
It is novel to be able to bear bigger pressure, and jet pipe 3 is not easy to plug, therefore coating is enable easily to penetrate into sand core surface layer, makes dope layer
Consistency is high, while having reached thickness of coating layer >=3mm of casting technique requirement, improves the surface quality of steel-casting, effectively
The generation of the casting flaws such as steel-casting scab, drop and sand holes is reduced, to reduce casting finish rehabilitation expense.
