Description

A high-efficiency mixing and fine grinding device for green silicon carbide raw materials Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a high-efficiency mixing and fine grinding device for green silicon carbide raw materials. Background Technology

[0002] Green silicon carbide is green in color and has a hexagonal crystal structure. It is brittle and sharp, and possesses excellent properties such as high packing density, strong grinding ability, strong cutting ability, and concentrated and uniform particle size distribution. Moreover, green silicon carbide can significantly enhance the performance of materials. In powder metallurgy, green silicon carbide is used as an additive or raw material to improve the wear resistance of alloys. Therefore, fine grinding equipment is needed to process and grind green silicon carbide raw materials. For example, a fine grinding processing device is disclosed in Chinese patent application number CN201922221536.7. It can uniformly stir the material in the processing tank and avoid the accumulation of material, thus accelerating the grinding process. However, the degree of fineness is not enough, as the material is not further filtered. In addition, the device does not have a centrifugal mechanism, which may lead to uneven distribution of grinding media in the container, thereby affecting the uniformity of grinding and the quality of the final product. Summary of the Invention

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a high-efficiency mixing and fine grinding device for green silicon carbide raw materials. The grinding effect is improved by the cooperation of the first gear, the second gear and the ring gear. Under the centrifugal action, the material distribution during the grinding process can be optimized, and the grinding disc can be used to impact and grind the material, thereby accelerating the crushing and refining of the material, which is conducive to improving the grinding quality. In addition, by cleaning the coarse filter screen in time during the grinding process, the clogging of the screen can be reduced.

[0004] This utility model also provides a high-efficiency mixing and fine grinding device for green silicon carbide raw materials, comprising: a support frame, a tank fixedly connected inside the support frame, an electric motor fixedly connected to the upper surface of the tank, a first conical shaft fixedly connected to the output end of the electric motor, a first gear fixedly connected to the outside of the first conical shaft, second gears meshing with the outside of the first gears, and ring gears meshing with the outside of the two second gears, the outer side of the ring gears being rotatably connected to the tank, and an inner cavity fixedly connected to the lower surface of the ring gears; a coarse filter screen and a fine filter screen fixedly connected to the inner wall of the inner cavity, a grinding shaft fixedly connected to the bottom end of the first conical shaft, a grinding disc fixedly connected to the bottom end of the grinding shaft, a fixing rod provided outside the grinding shaft, a scraper fixedly connected to the end of the fixing rod away from the grinding shaft, and a fan provided inside the inner cavity. The grinding effect is improved by the cooperation of the first gear, the second gear and the ring gear. Under the centrifugal force, the material distribution during the grinding process can be optimized, and the grinding disc can also impact and grind the material, thereby accelerating the crushing and refining of the material, which is conducive to improving the grinding quality. In addition, timely cleaning of the coarse filter screen during the grinding process can reduce the clogging of the screen opening.

[0005] According to the present invention, a high-efficiency mixing and fine grinding device for green silicon carbide raw materials includes two second conical piercing shafts fixedly connected inside each of the two second gears. The top ends of the second conical piercing shafts are rotatably connected to the upper top wall of the tank. This prevents the first conical piercing shaft from shaking or shifting during rotation, thereby ensuring the stability and reliability of the rotation.

[0006] According to the present invention, a high-efficiency mixing and fine grinding device for green silicon carbide raw materials is provided. A pipe is fixedly connected to the outlet of the blower, and a dust collector is fixedly connected to the end of the pipe furthest from the blower. The bottom of the dust collector is fixedly connected to the lower wall of the inner cavity. This device can directly extract dust generated during the grinding of the green silicon carbide raw materials and transport the dust to the dust collector through the pipe.

[0007] According to the present invention, a high-efficiency mixing and fine grinding device for green silicon carbide raw materials is provided on the outside of the tank, and a hopper is fixedly connected to the end of the feed pipe away from the tank. This facilitates the feeding of green silicon carbide raw materials through the hopper and the smooth addition of them into the tank through the feed pipe.

[0008] According to the present invention, a high-efficiency mixing and fine grinding device for green silicon carbide raw materials is provided, wherein the outside of the grinding shaft is rotatably connected to a coarse filter screen, and the coarse filter screen is in close contact with a scraper. The grinding shaft drives the grinding disc to rotate, and the scraper cleans the coarse filter screen in a timely manner to prevent clogging.

[0009] According to the present invention, a high-efficiency mixing and fine grinding device for green silicon carbide raw materials is provided, wherein the cross-section of the fine filter screen is a platform structure that gradually decreases from top to bottom, and the fine filter screen is located below the coarse filter screen. This increases the filtration area and subjectes the material to greater pressure and friction during the filtration process, thereby improving the filtration accuracy.

[0010] According to the present invention, a high-efficiency mixing and fine grinding device for green silicon carbide raw materials is provided inside the inner cavity, with two symmetrically distributed baffles located on both sides of the first conical shaft. The baffles allow the green silicon carbide raw materials to gather towards the center of the container, facilitating crushing of the raw materials.

[0011] According to the present invention, a high-efficiency mixing and fine grinding device for green silicon carbide raw materials is provided at the bottom of the inner cavity, and a discharge valve is provided at the connection between the discharge port and the inner cavity. The outflow of material is controlled by opening or closing the discharge valve, which precisely controls the flow rate of material from the inner cavity through the discharge port.

[0012] Beneficial effects: Compared with the existing technology, this new type of high-efficiency mixing and fine grinding device for green silicon carbide raw materials improves the grinding effect through the cooperation of the first gear, the second gear and the ring gear. Under the centrifugal action, the material distribution during the grinding process can be optimized, and the grinding disc can also generate impact and grinding action on the material, thereby accelerating the crushing and refining of the material, which is conducive to improving the grinding quality. In addition, timely cleaning of the coarse filter screen during the grinding process can reduce the clogging of the screen opening. Attached Figure Description

Through the cooperation of the first gear 4 and the second gear 5, the device can crush the green silicon carbide raw materials while the inner cavity 7 can rotate through the meshing of the second gear 5 and the ring gear 6, thereby allowing the material inside to be evenly distributed under centrifugal force.

[0024] The inner wall of the inner cavity 7 is fixedly connected to a coarse filter screen 8 and a fine filter screen 9 to ensure the purity and fineness of the grinding product, improve grinding efficiency, and enhance the grinding effect. The bottom end of the first conical shaft 3 is fixedly connected to a grinding shaft 10, and the bottom end of the grinding shaft 10 is fixedly connected to a grinding disc 11 to grind the crushed green silicon carbide raw material. A fixing rod 12 is set on the outside of the grinding shaft 10, and a scraper 13 is fixedly connected to the end of the fixing rod 12 away from the grinding shaft 10 to clean the coarse filter screen 8 and prevent the screen opening from becoming blocked. A fan 14 is set inside the inner cavity 7 to clean the dust in the inner cavity 7. The outlet of the fan 14 is fixedly connected to a pipe 18 to transport the dust to the dust collector 19 for collection and treatment. The end of the pipe 18 away from the fan 14 is fixedly connected to the dust collector 19, and the bottom of the dust collector 19 is fixedly connected to the bottom wall of the inner cavity 7.

[0025] A feed pipe 16 is provided on the outside of the tank body 1. A hopper 17 is fixedly connected to the end of the feed pipe 16 away from the tank body 1. Green silicon carbide raw material is fed in through the hopper 17. The outside of the roller shaft 10 is rotatably connected to the coarse filter screen 8. The coarse filter screen 8 is in close contact with the scraper 13. The cross-section of the fine filter screen 9 is a platform structure that gradually decreases from top to bottom, which increases the filtration area and improves the filtration accuracy.

[0027] Working principle: First, the green silicon carbide raw material is fed into the hopper 17 and enters the inner cavity 7 of the tank 1 through the feed pipe 16. Then, the motor 2 is started, driving the first gear 4 to rotate the two second gears 5. The two second gears 5 drive the second conical piercing shaft 15, and the first gear 4 drives the first conical piercing shaft 3. With the cooperation of the first conical piercing shaft 3 and the second conical piercing shaft 15, the green silicon carbide raw material can be crushed into small particles. Then, the particles crushed to a certain size pass through the coarse filter screen 8. As the green silicon carbide raw material falls above the fine filter screen 9, the activated fan 14 removes the dust from the raw material and transports it to the dust collector 19 through the pipe 18. At the same time, the first cone shaft 3 drives the grinding shaft 10 to rotate the grinding disc 11, thereby allowing the grinding disc 11 to finely grind the green silicon carbide raw material. The material is then filtered through the fine filter screen 9, and the filtered fine particles are stored at the bottom of the inner cavity 7. When discharge is required, the material is discharged through the discharge valve 21.
