The invention discloses a submicron silicon carbide grading device, which belongs to a grading device. The device mainly comprises a cylinder body, an end cover, a rotor and an adjusting disc, wherein the end cover is provided with a feeding hole, and the feeding hole is communicated with pressure slurry; the rotor is rotationally arranged in the cylinder body, and comprises a rotating shaft and a rotating disc which are fixedly arranged together; the adjusting disc is pressed on the rotating disc through a pressure adjusting device; the cylinder body is provided with a limiting piece only used for limiting the rotation of the adjusting disc; a first sealing piece is arranged between the peripheral surface of the adjusting disc and the inner wall of the cylinder body; and the jointed end faces between the rotating disc and the adjusting disc form a slurry grading passage. The device solves the technical problems of long hydraulic (settling and overflowing) grading time of submicron silicon carbide, low production efficiency and instable product. The device has a reasonable structure, and is widely applied to micro-power manufacture in other industries such as silicon carbide and the like.
Description
technical field [0001] The invention relates to a separation device, in particular to a device for wet separation of submicron silicon carbide powder. Background technique [0002] At present, in the production of micropowder, the powder whose maximum particle diameter is less than 5 microns is called submicron powder. Due to the small particle size of submicron powder, it is difficult to separate it by conventional classification devices. [0003] Most manufacturers use the sedimentation method to classify submicron powders. Mix silicon carbide micropowder with water and stir to make a suspension. After sedimentation and stratification, the submicron powders are extracted. Usually, the sedimentation time is long and the classification is difficult. Difficult to guarantee product quality and production efficiency. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a submicron silicon carbide grading device to solve...
