DETAILED DESCRIPTION

[0027] ​With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0028] Embodiment 1:

[0029] With reference to Figures 1-4 The utility model discloses a kind of grinding equipment for processing silicon carbide raw materials, including grinding tank 1, further comprising: fixed grinding wall 101, fixedly connected in grinding tank 1;Rotary grinding wall 2, rotatably connected in grinding tank 1, rotary grinding wall 2 and the grinding end of fixed grinding wall 101 are pasted;Connecting block 3, fixedly connected on rotary grinding wall 2;Conical cavity 302, is arranged in connecting block 3;Auger 602, rotatably connected in conical cavity 302, auger 602 and conical cavity 302 inner wall are pasted;Multiple groups of discharge holes 303, all are arranged on the small end of conical cavity 302, by auger 602 can be absorbed into the raw material of the bottom of grinding tank 1, then extruded by conical cavity 302, raw material is re-arranged to the above of grinding end, motor two 601 is fixedly connected in connecting block 3, the output end of motor two 601 and auger 602 are fixedly connected, motor one 5 is fixedly connected on grinding tank 1, motor one 5 and connecting block 3 are fixedly connected, rotary grinding wall 2 is provided with inclined plane 301 below discharge hole 303, convex ring 304 is fixedly connected on connecting block 3, connecting rod 7 matched with convex ring 304 is fixedly connected in grinding tank 1, convex ring 304 is located above discharge hole 303, inlet 102 and discharge outlet 103 are provided on grinding tank 1.

[0030] Because in the process of preliminary grinding, some particles of silicon carbide are directly discharged, it is necessary to re-grind to reduce the difference between the particles after grinding.

[0031] When the device is used, motor one 5 is started, and rotary grinding wall 2 is continuously rotated, at this time, the silicon carbide to be ground is poured into grinding tank 1 through inlet 102, and the silicon carbide is ground between fixed grinding wall 101 and rotary grinding wall 2, and the ground silicon carbide falls into the bottom of grinding tank 1 naturally.

[0032] In use, the motor two 601 can be started to drive the auger 602 to rotate, at this time, the rotation of the auger 602 can continuously suck the silicon carbide at the bottom into the conical cavity 302, and then the silicon carbide is continuously pressurized in the conical cavity 302 to be quickly discharged through the discharge hole 303, and then the silicon carbide is guided to above the fixed grinding wall 101 to be re-grounded, so that the ground particles can be as uniform as possible, and the situation that the particle size is too large is reduced.

[0033] The ground silicon carbide can be discharged through the discharge port 103.

[0034] The inclined surface 301 is used to guide the silicon carbide between the two groups of grinding walls, so that the silicon carbide can be ground, and the situation that the silicon carbide is accumulated above the grinding wall and is not ground is reduced.

[0035] The convex ring 304 and the connecting rod 7 are used to limit the connecting block 3, and ensure that the connecting block 3 can stably rotate.

[0036] Embodiment 2:

[0037] Referring to Figures 1-4 The grinding pot 1 is fixedly connected with the storage hopper 4 at the bottom of the fixed grinding wall 101, the storage hopper 4 is provided with a sieve hole at the bottom, and the auger 602 is attached to the storage hopper 4.

[0038] The storage hopper 4 is used to store the silicon carbide after preliminary grinding, and then the smaller particles fall into the bottom of the grinding pot 1 through the sieve hole, and the larger particles remain in the storage hopper 4 and will be sucked into the conical cavity 302 by the auger 602 to be re-grounded.

[0039] At the same time, after the auger 602 sucks away the larger silicon carbide, the silicon carbide accumulated on the storage hopper 4 can flow, so that the situation that the larger particles block the sieve hole and the smaller particles cannot fall is avoided.

[0040] The auger 602 and the conical cavity 302 can guide the particles after preliminary grinding at the bottom to above the grinding end to be re-grounded, so that the ground particles can be as uniform as possible, and the uniformity of the particle size can be realized.
