Description
Technical field
The invention belongs to high-pressure casting fields, and in particular to a kind of high-pressure casting aluminum water screen pipe.
Background technology
In foundry industry, it is a kind of very important type in casting flaw to be mingled with, account for the half of defect total amount with
On, all there may be this defects in all casting, and only severity is different.
In aluminium and Al alloy parts casting process, the impurity that aluminum water contains includes the oxygen containing calcium carbonate and iron, manganese, aluminium
The slag of compound, the inovulant particle not melted, sulfide, the solid impurities such as magnesium silicate, remaining solvent, the density of partial impurities
Close, field trash is difficult to float, and molten aluminum is fallen into from mould gate along with that may have other field trashes such as sand in casting process
In, if these liquid/solid non-metallic inclusions enter cast-internal with cast, it is easy to generate slag blister, sand holes, core
And other issues, it not only results in gas leakage and generates waste product, while can also influence the mechanical property of material.
Farthest to filter field trash, domestic and international manufacturing enterprise often places filter screen at cast gate, common are
Wire netting, fibrous filter net, foam ceramic filter, straight-bore ceramic filter.Traditional wire netting will have a direct impact on because of Fe harmful elements
The cast gate that mechanical castings scale off simultaneously cannot directly melt down use；Fibrous filter net filter effect is not good enough, is easy cracking
It is difficult that installation is fixed, casting is easily made to generate stomata, slag stomata class defect；Although foam ceramic filter and straight-bore ceramic filter aluminium skimmings
Use can be recycled, but filter screen manufacturing cost is high, it is frangible and be difficult to fix.
In addition, part strainer can also cause casting to generate gross blow hole greatly due to filter screen gas forming amount, lead to rate of wasted casting product
The problems such as raising.
Invention content
The object of the present invention is to provide a kind of high-pressure casting aluminum water screen pipes of energy high efficiency filter aluminium impurities in water.
It is a further object to provide a kind of high-pressure casting aluminum water screen pipes of low gas forming amount.
In order to solve the above-mentioned technical problem, the invention discloses a kind of high-pressure casting aluminum water screen pipes, including：Charging
Mouth, screen pipe and discharge port, in the shape of a spiral, both ends are connected with inlet port and outlet port screen pipe respectively, and screen pipe is by interior
Include the first filtering meshes, the second filtering meshes, third filtering meshes, protective layer and insulating layer, first filter screen outward
Layer, the second filtering meshes, third filtering meshes are detachable.Spiral helicine screen pipe make high pressure aluminum water by when quickly rotate,
The centrifugal force of generation gets rid of the impurity in aluminum water to filtering inside pipe wall, in addition, aluminum water flows through rough first filtering meshes table
It will produce sinuous flow when face, impurity driven to break through chimney filter inner wall, to be filtered by the first filtering meshes, the second filtering meshes, third
The cell absorption or retention that stratum reticulare is formed, achieve the purpose that impurity screening.
Preferably, one end caliber that the screen pipe is connected with feed inlet is more than what screen pipe was connected with discharge port
One end, screen pipe are gradually reduced from feed inlet one end to discharge port one end caliber；Since screen pipe is from feed inlet one end to discharging
Mouth one end caliber is gradually reduced, and under wind tunnel effect, speed of the aluminum water in screen pipe is getting faster, to make aluminium impurities in water
The centrifugal force being subject to is increasing, to make impurity be detached；One end internal diameter that the screen pipe is connected with discharge port does not surpass
12mm is crossed, if filtering bore is excessive, filter effect can be caused to be deteriorated or cannot play a role in filtering.
Preferably, first filtering meshes, the second filtering meshes, third filtering meshes dictyosome use 304 stainless steels
Net is as base material.
Preferably, first filtering meshes, the second filtering meshes, third filtering meshes dictyosome surface are coated with high temperature resistant
Coating or refractory material reduce harm of the Fe harmful elements to casting.
Preferably, the mesh diameter of first filtering meshes is 1.2-1.6mm, and porosity is 30-60 mesh.The filtering
Layer can retain large-sized impurity and bubble.
Preferably, the mesh diameter of second filtering meshes is 0.8-1.2mm, and porosity is 50-80 mesh.The filtering
Layer can retain the impurity and bubble of greater particle size.
Preferably, the mesh diameter of the third filtering meshes is 0.2-0.3mm, and porosity is 200-500 mesh.The mistake
Filtering layer can retain the smaller impurity and bubble of grain size.
Preferably, the protective layer is slim stainless steel materials, which can prevent aluminum water from penetrating, and to the first filter screen
Layer, the second filtering meshes, third filtering meshes play the role of fixing and supporting.
Preferably, the insulating layer is ceramic thermal insulation material, prevents aluminum water from occurring significantly cooling down in filtering.
Preferably, the middle vacancy of the spiral screen pipe is equipped with Elema heating tube, plays compensation heating
Effect.
It should be noted that the present invention is poor less than the contaminant filter effect of 0.2mm to grain size in aluminum water, but the part is miscellaneous
The influence of confrontation casting quality is smaller.
Advantageous effect：
The present invention high-pressure casting aluminum water screen pipe, aluminum water be not necessarily to penetrate screen pipe, can effectively reduce filtration resistance and
Reduce filtering in strainer gas forming amount, when aluminum water high speed pass through screen pipe when, impurity is adsorbed or is retained by its inner wall, can reach compared with
Good filter effect.
