The crushing rod 8 is inclined, and the crushing rods 8 are evenly distributed on the outside of the second rotating shaft 7, which increases the rotation speed of the crushing rod 8 and is conducive to the crushing rod 8 breaking up the agglomerated silicon carbide micropowder.

[0035] The vibration mechanism includes a fixing plate 12. The fixing plate 12 is fixedly attached inside the drying box 1 and inside the conveyor belt 3. Both sides of the top of the fixing plate 12 are fixedly attached with fixing cylinders 13. A spring 14 is fixedly attached to the bottom inside the fixing cylinder 13. The top of the spring 14 is fixedly connected to an inner rod 15. The top of the inner rod 15 penetrates through the inside of the fixing cylinder 13 and is fixedly connected to the bottom of a top plate 16. A vibration motor 17 is fixedly attached to the bottom of the top plate 16. A groove 18 is opened on the top of the top plate 16. A third rotating shaft 19 is rotatably installed inside the groove 18 through bearings. A guide post 20 is nested and fixedly attached to the outer wall of the third rotating shaft 19. The top of the guide post 20 penetrates through the top of the top plate 16 and is mutually attached to the top inside the conveyor belt 3.

The top of the scraper 30 abuts against the bottom of the conveyor belt 3. The silicon carbide micropowder on the conveyor belt 3 can be scraped into the inside of the collection box 23 through the scraper 30, avoiding the waste of silicon carbide micropowder.

[0041] Working principle: When using this drying equipment for silicon carbide micropowder, first remove the top cover 11 from the top of the storage bin 5, then pour the silicon carbide micropowder to be dried into the inside of the storage bin 5, and then start the rotary motor 4 to drive the first rotating shaft 2 and the conveyor belt 3 to rotate clockwise. The silicon carbide micropowder inside the storage bin 5 and the discharge pipe 6 is spread flat on the top of the conveyor belt 3 through the discharge port 31. When the rotary motor 4 is started, the rotary motor 4 drives the second rotating shaft 7 and the crushing rod 8 to rotate through the first rotating shaft 2, the second gear 10 and the first gear 9, breaking up the agglomerated silicon carbide micropowder inside the discharge pipe 6, which is beneficial for the silicon carbide micropowder to pass through the inside of the discharge port 31;

[0042] Start the electric heating rod 26 to heat the air inside the drying oven 1, and the heated air dries the silicon carbide micropowder laid flat on the top of the conveyor belt 3. Start the vibration motor 17, and the vibration motor 17 drives the top plate 16 to vibrate up and down through the spring 14 and the inner rod 15, thereby driving the silicon carbide micropowder on the top of the conveyor belt 3 and the conveyor belt 3 to vibrate up and down, so that the silicon carbide micropowder can be evenly heated, improving the drying efficiency of the silicon carbide micropowder. When the conveyor belt 3 continues to rotate clockwise, the dried silicon carbide micropowder on the top of the conveyor belt 3 falls into the inside of the collection box 23 through the through groove 21, completing the centralized collection of the dried silicon carbide micropowder.
