Technical Field
[0001] The utility model relates to the technical field of separation equipment, in particular to a silicon carbide powder screening device. Background Art
[0002] Silicon carbide has four major application areas, namely: functional ceramics, advanced refractory materials, abrasives and metallurgical raw materials. Silicon carbide belongs to the third generation of semiconductor materials. Compared with ordinary silicon materials, silicon carbide has outstanding advantages. It not only overcomes some shortcomings of ordinary silicon materials, but also has very good performance in power consumption, thus becoming the most promising semiconductor material in the field of power electronics.
[0003] Silicon carbide is often processed into granular powder during preparation to facilitate subsequent processing operations. However, the hardness of silicon carbide raw materials is relatively high, and iron filings from the crushing equipment will be mixed into the raw materials during the crushing process.

In addition, when preparing different finished products, silicon carbide powders of different particle sizes are required. In the prior art, although the iron removal equipment has a screening structure, the size of the screening particle size is often not adjustable. After the preliminary screening, the powder needs to be screened using professional screening equipment, and the process is relatively cumbersome. Utility Model Content

When the powder falls in the inner cylinder, it contacts the electromagnetic guide plate, which is energized to carry magnetic force, and the iron filings in the powder are adsorbed. At the same time, silicon carbide powder particles fall into the rotating inner cylinder, are screened out through the staggered leakage holes and are placed in the receiving box for screening. Subsequently, the mounting plate and the electromagnetic guide plate are removed and the power is turned off to allow the iron filings to fall and be collected.
