After the adoption of the structure, the utility model can realize that the mixture material can not only move along the rotation direction of the stirring blades in the stirring barrel but also thresh from the outside to the inside and from the lower to the upper, thus attaining the strong stirring mixed effect, improving greatly the mixed equality of the mixture, and achieving the even stirring mix of tungsten powder and black carbon.
Description
Technical field
The utility model relates to a kind of metal smelting device, particularly relates to a kind of mixer that is used to prepare tungsten carbide powder.
Background technology
Tungsten is a kind of metal of infusibility, fusing point up to 3410 ℃ about, its hardness height, ductility is strong, be not subjected to the erosion of air under the normal temperature,, make that the range of application of tungsten powder is comparatively extensive just because of tungsten has these characteristics, as can be used for preparing high-density alloy, be applied to automatic watch pendulum, telecommunication ticker, aircraft balanced plate, anti-χ ray, alpha ray, gamma-rays baffle or the like; Also can be used for preparing electrical alloy, as high-voltage contact etc.Tungsten carbide powder is an important source material of making alloy, and the carbide alloy that is prepared by tungsten carbide can be used for making miniature brill, making oil bit, making lathe tool, milling cutter, the boring cutter of producing surface-mounted integrated circuit, makes diamond or the like.With the superfine tungsten carbide is the carbide alloy that raw material is made, it is very high that its hardness of alloy and intensity can reach, overcome the contradiction that its intensity of micron order Talide and hardness can not improve simultaneously fully, in the market, the price of high-performance superfine tungsten carbide is about 1.5～2.0 times of common micron order tungsten carbide powder, compare with the common micron order tungsten carbide powder of production and produce superfine tungsten carbide, both production costs are basic identical, then obvious, produce superfine tungsten carbide and can bring bigger added value of product, superfine tungsten carbide is the better substitute products of common micron order tungsten carbide powder.In the preparation process of product, because ultrafine tungsten powder and ultra-fine carbon black is mobile very poor, the apparent density of micron order tungsten powder and carbon black differs bigger, when the ball mill mode ball milling mixing tungsten powder of employing prior art and carbon black, both are difficult to mix, and the ball milling incorporation time is very long, noise is big, production efficiency is low, simultaneously, owing to grind spheroid wearing and tearing mutually between wearing and tearing and spheroid and the ball mill barrel mutually, thus cause pollution to product, the chemical purity of product is descended, influenced product quality.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art, a kind of mixer that is used to prepare tungsten carbide powder is provided, realize improving the particularly mixing uniformity of ultrafine tungsten powder and ultra-fine carbon black of tungsten powder and carbon black, the ball milling incorporation time of having avoided employing ball mill mode to be caused is very long, drawbacks such as noise is big, and production efficiency is low; Make the tungsten powder and the carbon dust that mix be easy to clean out, avoid the cross pollution of size fractionated powder, also can avoid adopting the ball milling hybrid mode to bring objectionable impurities elements such as iron, nickel, chromium into simultaneously, improve the purity of tungsten carbide product.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of mixer that is used to prepare tungsten carbide powder, it comprises a sealable cylindrical shell, a bearing, a drive motors, a workbench, cylindrical shell is fixed on the bearing, bearing, drive motors are individually fixed on the workbench, the top of cylindrical shell is provided with air-pressure type cover and sealable charging aperture, but the bottom of cylindrical shell is provided with the discharging opening of stirring blade and pressurized seal, stirring blade and stirring shaft fixedly link, and stirring shaft is by motor-driven; The outer wall of cylindrical shell is coated with water chamber; One inlet channel feeds stirring shaft, and is entered in the cylinder chamber by slit between axis hole.
Described cylindrical shell bottom is than the orthodrome transition to sidewall by diapire.
The curved upwards bending in the edge of described stirring blade.
In use, open the charging aperture on cylindrical shell top, tungsten powder and carbon black ratio are on request put into cylindrical shell, charging aperture is covered; The air-pressure type cover that its cylindrical shell top is set is mainly used in the time of need cleaning cylindrical shell, just opens and uses; After ultrafine tungsten powder and ultra-fine carbon black are put into cylindrical shell, starter motor, machine operation, machine shaft begins to rotate, machine shaft drives stirring shaft by belt pulley or sprocket wheel and rotates, stirring shaft is contained in the bearing, its upper and lower is contained in the bearing by a bearing respectively, the bottom of stirring shaft joins by drive and machine shaft transmission, after stirring shaft rotates, drive the stirring blade that is fixedly connected with its middle part and rotate, be than the orthodrome transition to sidewall, the curved upwards bending in the edge of stirring blade because the bottom of cylindrical shell is made as by diapire, the stirring that this structure produced, make the material in the mixing drum not only move along the rotation direction of stirring blade, but also from outside to inside, roll from bottom to top, realized the uniformity that stirs.When stirring, also in cylindrical shell, feed inert gas, inert gas is to enter stirring shaft by an external tracheae and through inlet channel, enter in the cylinder chamber by slit between axis hole again, the inert gas one that is entered by this place is can prevent in the mixed process, and mixed material is because of the too high issuable burning of surface energy; The 2nd, air-flow enters from here, can prevent that the interior coccoid of tube from falling from the slit of stirring shaft and cylindrical shell bottom connection, is stuck on the joining bearing of stirring shaft and bearing, bearing can not be rotated, and then influence the use of mixer.After stirring, disable motor, motor is stopped operating, and then stirring blade also stops operating, and stirring stops, at this moment, can in the water chamber that cylinder body outer wall coated, inject water, the mixed material in the tube is cooled off, after cooling is good, open the discharging opening of pressurized seal, the material after mixing is derived.
The beneficial effects of the utility model are, owing to adopted the mode of mixer that tungsten powder is mixed with carbon black, the ball milling incorporation time of having avoided employing ball mill mode to be caused is very long, noise is big, production efficiency is low, drawbacks such as mixing uniformity is relatively poor, improved the homogeneity that mixture mixes greatly, thereby can improve the homogeneity of the copmbined-carbon and the tungsten-carbide powder carbon of tungsten-carbide powder, reduce the hard granule of sintering in the tungsten-carbide powder, growing up unusually of tungsten carbide crystal grain appears when preventing alloy sintering, reduce simultaneously iron in the tungsten-carbide powder significantly, nickel, objectionable impurities constituent contents such as chromium help improving the quality of carbide alloy; Owing to being made as by diapire, the cylindrical shell bottom is than the orthodrome transition to sidewall, and the edge of stirring blade made upwards bending of arc, make material in mixing drum not only the rotation direction along stirring blade move, but also from outside to inside, roll from bottom to top, can obtain strong stirring and mixing effect, mixed material is very even; Owing to establish an inlet channel at stirring shaft and cylindrical shell bottom connection place, make the inert gas that enters from here both can prevent in the mixed process, mixed material is because of the too high issuable burning of surface energy; Can also prevent that the interior coccoid of tube from falling from the slit of stirring shaft and cylindrical shell bottom connection, be stuck on the joining bearing of stirring shaft and bearing, bearing can not be rotated, and then influence the use of mixer.
