Description

Technical Field

[0001] The utility model relates to the technical field of silicon carbide ceramic processing, in particular to a granulation system for silicon carbide ceramics. Background Art

[0002] Silicon carbide ceramics have the advantages of good chemical corrosion resistance, high strength, high hardness, good wear resistance, low friction coefficient, oxidation resistance, low high-temperature creep, and good thermal stability. They are widely used in mechanical chemical industry, environmental protection, information electronics, automobile, energy and other fields.

[0003] After searching, the patent number CN202322245902.9 discloses a granulation system for silicon carbide ceramics. This solution sets two symmetrically distributed granulation rollers on the inner side of the machine body. When the granulation rollers rotate, the silicon carbide ceramics can be granulated. However, the silicon carbide ceramic raw materials are often not uniform enough. When adding silicon carbide ceramics, agglomeration is often accompanied. The current device lacks a dispersion mechanism for the silicon carbide ceramic raw materials, and the loading is not uniform enough, and the granulation effect of the silicon carbide ceramics cannot be guaranteed. Therefore, it needs to be improved. Utility Model Content

[0010] The dispersion mechanism is installed on the inner side of the machine body. The dispersion mechanism includes a reciprocating screw rotatably connected to the machine body, and a sliding block adapted to the reciprocating screw.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a granulation system for silicon carbide ceramics, which has the following beneficial effects:

[0018] The utility model installs a dispersion mechanism on the inner side of the machine body, and the dispersion mechanism is mainly composed of a reciprocating screw, a guide rod, a rack, a sliding block, a gear, an ear plate, a shaft rod, a crushing blade, etc. When the silicon carbide ceramic is granulated, the motor drives the granulation roller to rotate. At this time, the rotating shaft on the granulation roller rotates, and the rotating shaft shakes the driving wheel to rotate, and then the reciprocating screw rod is driven to rotate through the relationship between the synchronous belt and the driven wheel. When the reciprocating screw rod rotates, the sliding block can move along the guide rod, and then the shaft rod and the crushing blade are rotated.
