Abstract

The utility model relates to a multi-hole solid ceramic filter screen. The multi-hole solid ceramic filter screen is characterized by being simple in structure and high in efficiency and comprising a ceramic filter screen body. The ceramic filter screen body comprises a ceramic netting-wire and holes which are formed among the ceramic netting-wire. The inner portion of the ceramic netting-wire is of a solid structure. Due to the fact that the screen diameter of the ceramic netting-wire of the filter screen is solid and the ceramic netting-wire is burned into a three-dimensional network structure of high strength and multiple layers of holes in space, the mechanical strength of the filter screen is large, the thermal shock resistance is good, the thermal-shock resistance performance and the scour resistance performance are good, the mechanical property is excellent and the service life is long. Due to the fact that the porosity of the holes on the ceramic filter screen body is more than 92%, the metal melt penetrating ability is high, the inflation property is low, the filter screen does not fracture and drop off, effects of filtration, edulcoration and deaeration are stable and good, the strength, toughness and machining performance of castings are improved and cost of the castings is saved.

Description

Porous solid ceramic screen pack
Technical field
The utility model relates to a kind of screen pack, is specifically related to a kind of hot investment casting foam ceramic filter, particularly a kind of porous solid ceramic screen pack.
Background technology
Filter of the prior art is casting resistance to sudden heating ceramic foam filter, and adopting foamed plastics is that presoma slip casting is made, and filter comprises the screen pack with continuous through hole, is bonded with the cushion of pyrolytic at the upper surface of screen pack; The porous foam ceramic filter net that when traditional screen pack is a kind of casting metals liquid metal liquid is filtered, comprise take Tercod as main, be equipped with the mixed slurry that schmigel, clay are made, stick on the polyurethane foam carrier, form the tridimensional network of spatial multi hole through sintering, be interconnected between each adjacent holes and tortuous making a circulation, porosity is greater than 90%.The problem that this foamed ceramics in use occurs is: the net of screen pack directly is hollow net footpath, and net footpath wall is thin, and is large because of casting stream, to the impulsive force damage aggravation in screen pack net footpath, causes that screen pack is cracked to come off, and impact is to the filter effect of molten metal; And can cause screen pack because cracked coming off is mingled with the material of large volume to molten metal---cracked of screen pack, the quality harm to foundry goods loses filtration.
Therefore, produce a kind of simple in structure, the net porosity is large, and heat shock resistance and performance of flushing are good, and mechanical property is excellent, long service life, screen pack can crackedly not come off, and the filtering and impurity removing degassing effect is stable good, can improve cast product intensity, toughness and processing characteristics, and can reduce the porous solid ceramic screen pack of casting cost, have wide market prospects.
Summary of the invention
For the deficiencies in the prior art, the utility model provides that a kind of simple in structure, net porosity is large, heat shock resistance and performance of flushing is good, mechanical property is excellent, long service life, screen pack can crackedly not come off, the porous solid ceramic screen pack of stable good, the high efficiency of filtering and impurity removing degassing effect.
The technical solution of the utility model is achieved in that a kind of porous solid ceramic screen pack, comprise the foam ceramic filter body, described foam ceramic filter body is by ceramic twine and be arranged on that cavity between the ceramic twine forms, and described ceramic twine inside is solid construction.
Be interconnected between the described cavity and tortuous making a circulation, cavity porosity on the foam ceramic filter body is not less than 92%.
Described foam ceramic filter body be shaped as tridimensional network.
The utlity model has following good effect: the utility model is simple in structure, high efficiency, comprise the foam ceramic filter body, described foam ceramic filter body is by ceramic twine and be arranged on that cavity between the ceramic twine forms, described ceramic twine inside is solid construction, because the ceramic network silk screen of screen pack directly is solid net footpath, sinter the tridimensional network of high strength spatial multi hole into, the mechanical strength of screen pack is large, good thermal shock stability, have good heat shock resistance and performance of flushing, mechanical property is excellent, long service life, and cavity porosity on the foam ceramic filter body is not less than 92% in addition, therefore have very high metal bath and see through ability, and extremely low initiation, screen pack can crackedly not come off, and the filtering and impurity removing degassing effect is stable good, can improve cast product intensity, toughness and processing characteristics, and can reduce casting cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is ceramic twine truncation surface structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, 2, a kind of porous solid ceramic screen pack, comprise the foam ceramic filter body, it is characterized in that: described foam ceramic filter body is by ceramic twine 1 and be arranged on that cavity 2 between the ceramic twine 1 forms, and described ceramic twine 1 inside is solid construction.
Be interconnected between described empty 2 and tortuous making a circulation, cavity 2 porosity on the foam ceramic filter body is not less than 92%.Described foam ceramic filter body be shaped as tridimensional network.
The utility model pottery twine 1 adopts solid net gauge structure, do not need presoma, directly slurry is made into solid wire, coiling stack by computer program control solid wire, form the tridimensional network of multilayer hole, be interconnected between the cavity 2 and tortuous making a circulation, cavity 2 porosity on the foam ceramic filter body is not less than 92%, production technology is easily controlled, and is simple to operate.During use, can be different according to requirements such as casting mold size, material, flow and temperature, select the porous ceramics screen pack of different computer program control hole size and number.
