For solving the problems of the technologies described above, technical scheme of the present invention is: submicron silicon carbide grading device, comprise the cylindrical shell and the end cap that are fixed together, and described cylindrical shell is provided with discharging opening, and described end cap is provided with charging aperture, and described charging aperture is communicated with the pressure slip; Rotation is installed on the rotor in the described cylindrical shell, and described rotor comprises rotating shaft and the rolling disc that is fixedly installed togather, and stretch out from the charging aperture of described end cap an end of described rotating shaft, is used for being connected with power set; The adjustment dish, described adjustment dish is pressed against on the described rolling disc by pressure regulation device, and described cylindrical shell is provided with and only is used to limit the locating part that described adjustment dish rotates, described locating part and the clamping of described adjustment dish; Be provided with first seal between the outer peripheral face of described adjustment dish and the inwall of cylindrical shell; Applying end face between described rolling disc and the described adjustment dish forms slip classification passage, and the outside of described slip classification passage communicates with described discharging opening, the inboard and the feeding inlet of described slip classification passage.
As a kind of improvement, described pressure regulation device comprises the compression spring; Adjust screw mandrel, described adjustment wire rod thread is connected on the described end cap and by spring capping will compress the spring roof pressure on described adjustment dish.
As further improvement, the inwall of described cylindrical shell is provided with annular groove, and described annular groove is corresponding with the position of described slip classification passage, and described annular groove is communicated with described discharging opening.
As further improvement, described adjustment dish is provided with a central through hole, described central through hole is passed in described rotating shaft, has toroidal cavity between the inwall of described rotating shaft and described central through hole, and the inboard of described slip classification passage is by described toroidal cavity and described feeding inlet.
As further improvement, be provided with second seal between the outer peripheral face of described rolling disc and the inwall of described cylindrical shell.
Owing to adopted technique scheme, the invention has the beneficial effects as follows: because rolling disc and rotating shaft are rotated together, the adjustment dish is then owing to the position-limiting action that is fixed on the locating part on the cylinder inboard wall can not rotate with rolling disc, had between adjustment dish and the rolling disc and relatively rotated, destroyed the diaphragm seal between adjustment dish and the rolling disc, make slurry overcome the pretightning force of pressure regulation device under pressure, flow out by the classification passage between rolling disc and the adjustment dish; Because relatively rotating of rolling disc and adjustment dish makes oarse-grained carborundum can not pile up in the joint place of rolling disc and adjustment dish, improved production efficiency; Owing to pressurize in slip, the particulate that makes it possible to overcome the pressure regulation device pretightning force can be by the classification passage, and the particle that can not overcome the pressure regulation device pretightning force then can not play the effect of classification by the classification passage; Owing to be provided with first seal between the outer peripheral face of adjustment dish and the inwall of cylindrical shell, make slurry to discharge by the classification passage between adjustment dish and the rolling disc, avoided unassorted slurry to sneak in the finished product slurry, improved the qualification rate of finished product slurry.
Owing to designed in pressure regulation device and the slurry and be connected with pressure, the size of pressure in pretightning force by adjusting the compression spring and the slurry, can overcome the pressure regulation device pretightning force and granular size by the classification passage changes, thereby isolate the silicon carbide micro-powder of the different different stage of diameter, satisfied different needs.
