Abstract
The utility model discloses a novel composite foam ceramic filter comprising a small filter and a large filter, which are concentric and cylindrical, wherein the large filter and the small filter are combined up and down to sinter into a whole at high temperature; high-temperature-resisting wrappers are arranged at the connected step of the small filter and the large filter, and the outer side of the small filter; the high-temperature-resisting wrapper at the outer side of the small filter is lower than the small filter; the high-temperature-resisting wrappers are high-temperature-resisting fiber papers or fiber felts; and the thicknesses of the high-temperature-resisting are 0.1-6mm. when the novel composite foam ceramic filter is used, one end of the small filter penetrates inside a riser tube; the large filter is positioned outside the riser tube to play a supporting role; the high-temperature-resisting fiber wrappers mainly play the roles of protecting and fixing the filters and preventing aluminum water from laterally leaking, have the filter effects of the filters, and do not introduce impurities such as iron; meanwhile, no slag easily falls off when the novel composite foam ceramic filter is in use; and the novel composite foam ceramic filter is firm and durable, high in strength, and good in filter effect, and has great significance on generalization.
Description
Technical field
The utility model relates to a kind of casting industry filter, particularly a kind of NEW TYPE OF COMPOSITE ceramic foam filter.
Background technology
Ceramic foam filter is a kind of filter that nearly twenty or thirty grew up over year, pass through ceramic filter, can effectively remove or reduce the field trash in the founding molten metal, improve the degree of purity of metal liquid, the metal casting smooth surface that founding is gone out, even structure, intensity improves, percent defective reduces, and has further reduced the machined loss simultaneously, has improved labor productivity.The casting of metals that this series products is mainly used in casting industry filters, and is applicable to the casting of cast steel, cast iron, cast aluminium, alloy, non-ferrous casting and the casting of heavy castings.Therefore product is widely used in the casting of the various foundry goods of the machine building industries such as automobile, shipbuilding, locomotive, agricultural machinery, building machinery, Aeronautics and Astronautics, lathe, electrical equipment, engineering pipeline, valve, pipe fitting.The filter type of aluminum current wheel hub cast aluminum-molykote composite material water generally uses wire netting or ceramic foam filter.Using wire netting is easily to bring iron into, reduce the performance of aluminium wheel hub, and filter capacity is limited; Use conventional ceramic filter to have good filter effect, need to be in stalk reserved location, easily collide slag in use procedure, What is more, in actual mechanical process because molten metal inflow amount is excessive, can damage filter, cause the filter fragmentation to enter foundry goods, cause foundry goods to produce defective.Patent CN201482323U discloses a kind of stalk mouth glass fibre filter bag for the wheel hub casting, stop to increase the iron-holder of aluminium liquid, but filter effect is general.
Summary of the invention
Technical problem to be solved in the utility model is the problem that exists for prior art, and a kind of existing good filter effect is provided, again sturdy and durable, the ceramic filter of not introducing new impurity.
For solving this technical problem, the utility model provides a kind of NEW TYPE OF COMPOSITE ceramic foam filter, comprises concentric cylindrical small filter and large filter, and described small filter and large filter make up through high temperature sintering up and down and be integral; On small filter and step surface that large filter is connected and the outside of small filter be provided with high temperature resistant integument.
The height of the high temperature resistant integument in the described small filter outside is lower than the height of small filter.
Described high temperature resistant integument is high-temperature fibre paper or fibrofelt, and its thickness is 0.1 ~ 6mm.
Beneficial effect: when the utility model uses, small filter one end is goed deep into stalk inside; large filter is in stalk and plays a supportive role outward; the high-temperature fibre integument mainly plays protection, Fixed-Filter and prevents that aluminium water side is excessive; the filter effect of existing filter can not introduced again the impurity such as iron, is difficult for falling slag in use procedure simultaneously; sturdy and durable; have intensity large, the characteristics of good filtration effect have dissemination.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is generalized section of the present utility model.
In figure: 1 small filter, 2 large filters, 3 high temperature resistant integuments.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is done specific descriptions.
Figure 1 shows that structural representation of the present utility model;
Figure 2 shows that generalized section of the present utility model.
The utility model provides a kind of NEW TYPE OF COMPOSITE ceramic foam filter, comprises concentric cylindrical small filter 1 and large filter 2, and described small filter 1 and large filter 2 make up through high temperature sintering up and down and be integral; On small filter 1 and step surface that large filter 2 is connected and the outside of small filter 1 be provided with high temperature resistant integument 3.
The height of the high temperature resistant integument 3 in described small filter 1 outside is lower than the height of small filter 1.
Described high temperature resistant integument 3 is high-temperature fibre paper or fibrofelt, and its thickness is 0.1 ~ 6mm.
During use, that small filter 1 insertion stalk is inner, large filter 2 is in outside stalk, and high temperature resistant integument 3 mainly plays a part fixing and prevents that aluminium water side is excessive.
The 20ppi aluminum oxide ceramic filter that described small filter 1 is diameter=49mm, thickness=48mm;
The 20ppi aluminum oxide ceramic filter that described large filter 2 is diameter=74mm, thickness=12mm;
Described high temperature resistant integument 3 is the high-temperature fibre paper of the alumina silicate material of width=30mm, thickness=3mm.
Embodiment 2
The 30ppi zirconium oxide ceramic filter that described small filter 1 is diameter=47mm, thickness=28mm;
The 30ppi zirconium oxide ceramic filter that described large filter 2 is diameter=68mm, thickness=15mm;
Described high temperature resistant integument 3 is the high-temperature fibre of the aluminium oxide material of width=20mm, thickness=3mm
The filter effect of the existing filter of the utility model can not introduced again the impurity such as iron, is difficult for falling slag in use procedure simultaneously, and is sturdy and durable, has intensity large, and the characteristics of good filtration effect have dissemination.
The above-mentioned embodiment of the utility model just illustrates, and is not only, all in the utility model scope or the change that is equal in scope of the present utility model all surrounded by the utility model.
