Description
Affiliated technical field
The utility model relates to the carbon removing device in a kind of preparation of silicon carbide micro-powder, particularly a kind of synchronous device except free carbon in silicon carbide micropowder.
Background technology
Silicon carbide has very high hardness, chemical stability and certain toughness, is widely used in sealing member, ballistic resistant sheet, high temperature nozzle, mill Jie, solar cell etc.Along with scientific and technical progress, the demand of carborundum powder is in continuous increasing, and purity requirement and globule size are also more and more higher.Purity is high, fine size, grain type are good, supply falls short of demand especially for the silicon carbide sub-micro ground rice of grain group essence.
Uncombined carbon in silicon carbide not only can produce spot to silicon carbide sintered article, flower prints, and the uncombined carbon in silicon carbide is active not enough, in the sintering of silicon carbide articles, do not have the effect of carbon source, affect on the contrary the specification of quality such as density of silicon carbide articles, so silicon carbide micro-powder needs to remove uncombined carbon in the process of preparation.
Removing at present the main method that uncombined carbon in silicon carbide micro-powder adopts is, utilizes deionized water and silicon carbide micro-powder to mix, stir, and silicon carbide micro-powder is carried out to classification, removes the uncombined carbon in silicon carbide micro-powder simultaneously.As Patent Office of the People's Republic of China's on December 30th, 2009 disclosed " a kind of method of removing free carbon from silicon carbide micro powder " by name, number of patent application: 200910065419.4, the method is to utilize addition polymerization liquid collecting in fractionated container, the a small amount of uncombined carbon that floats over gathering liquid surface is removed, then precipitation, discharge, carry out de-carbon by the color of discharge port in discharge process.The method is to operator's requirement is very high, technique is loaded down with trivial details, labour intensity is large, long processing period.
Summary of the invention
The purpose of this utility model is the defect that overcomes prior art, provides a kind of by the refinement of silicon carbide micro-powder with remove uncombined carbon and organically combine, and de-carbon is effective, the simple synchronous device except free carbon in silicon carbide micropowder of technique.
For realizing the purpose of this utility model, the technical solution of the utility model is: a kind of synchronous device except free carbon in silicon carbide micropowder, comprise with whipping appts with the container of water jacket, opening for feed and discharge gate are installed on container, it is characterized in that the discharge gate in said vesse is connected with the opening for feed of silicon carbide sand grinding machine by marker pipe, discharge pump is installed on marker pipe, opening for feed in said vesse is connected with the discharge gate of silicon carbide sand grinding machine by feeding pipe, and fresh feed pump is installed on feeding pipe.
The whipping appts being arranged on said vesse is comprised of the vertical axes being connected with motor and two stirring rakes that are arranged on vertical axes upper and lower end, the upper and lower end of the water jacket in container is provided with water coolant inlet tube and outlet tube, bottom at container is provided with discharge gate, has uncombined carbon relief outlet on the sidewall on container top.
The above-mentioned stirring rake that is arranged on vertical axes upper end is straight-plate-type stirring rake, and its height location is corresponding with uncombined carbon relief outlet; The stirring rake that is arranged on vertical axes lower end is pusher stirring rake.
The technical solution of the utility model has following characteristics:
1, technique is simple, with short production cycle: the utility model organically combines silicon carbide sand grinding machine and carbon removing device, in silicon carbide thinning process, just the uncombined carbon in silicon carbide can be removed automatically by carbon removing device, can effectively be shortened the production cycle 30-50%;
2, treatment effect is good: the content of the type silicon carbide Free Carbon after the utility model is processed is less than 0.1%;
3, except carbon efficiencies is high: the utility model only need to add appropriate flotation oil in the process of the refinement of silicon carbide micro-powder, and the uncombined carbon of floating can be scraped to uncombined carbon clearing device by the overflow notch on uncombined carbon clearing device, except carbon efficiencies high;
4, with low cost: the flotation oil that the utility model adopts, 1 ton of α type silicon carbide micro-powder of every production, cost only increases 5-20 yuan, with low cost.
