Primarily composed of rare earth element oxides, it features high hardness, high polishing efficiency, and good stability, thus finding wide application in optics, electronics, and precision machinery. During processing, rare earth polishing powder requires slurry grinding, necessitating the use of slurry grinding equipment.

[0003] Chinese patent discloses a ball milling device for rare earth polishing powder on semiconductor wafers (authorization announcement number CN217341625U). This patented technology includes a body, a guide tube, and a lubrication device.

Detailed Implementation

[0018] Please see Figures 1-3 In this embodiment of the present invention, a high-efficiency homogeneous rare earth polishing powder slurry grinding device includes a base 10 and a grinding roller 1 located on the base 10. Two guide rings 2 are fixedly connected to the outer side of the upper end of the grinding roller 1. A set of support rollers 11 are provided at the lower end of the two guide rings 2 at the upper end of the base 10. The support rollers 11 support and limit the grinding roller 1, so that the grinding roller 1 can roll on the support rollers 11. A toothed ring 4 is fixedly connected to one end of the outer side of the grinding roller 1, and a motor 7 is installed on one side of the upper end of the base 10. The output end of the motor 7 is fixedly connected to a drive gear 8, which meshes with the toothed ring 4. A feeding device is embedded through one end of the grinding roller 1. Mechanism 3, and a slurry adjustment mechanism 5 is embedded at the other end of the grinding roller 1. A discharge gate 9 is set on the outer side of the grinding roller 1 between a set of guide rings 2. After opening the discharge gate 9, steel balls for grinding rare earth polishing powder raw materials, such as lanthanum and cerium carbonate, can be added to the grinding roller 1. The motor 7 drives the drive gear 8 to rotate. The drive gear 8 meshes with the gear ring 4 to transmit power, so that the grinding roller 1 rolls on the support roller 11. During the rolling process, the grinding roller 1 drives the steel balls to rotate together, and the polishing powder raw materials are ground by the moving steel balls. When the lanthanum and cerium carbonate are ground, the discharge gate 9 is opened so that the position of the discharge gate 9 is downward, and the slurry-adjusted and ground rare earth polishing powder raw materials can be poured out.

[0019] exist Figure 1 and Figure 2In the process, the feeding mechanism 3 includes a cylindrical shell 31. A second motor 33 is installed at one end of the cylindrical shell 31, and a support shaft 36 is installed at the other end of the cylindrical shell 31. An auger 34 is installed inside the cylindrical shell 31 at the output end of the second motor 33. A feed inlet 32 ​​is provided at the upper end of the cylindrical shell 31 near the second motor 33, and a discharge outlet 35 is provided at the lower end of the cylindrical shell 31 near the support shaft 36. A shaft seal 37 is installed on the outer side of the cylindrical shell 31 between the feed inlet 32 ​​and the discharge outlet 35. The cylindrical shell 31 is rotatably mounted on the inner side of one end of the grinding roller 1 via the shaft seal 37. The discharge port 35 is located inside the grinding roller 1, and the feed port 32 is located outside the grinding roller 1. Rare earth polishing powder raw material is added through the feed port 32, and then the auger 34 is driven to rotate by the motor 33. The auger 34 conveys the rare earth polishing powder raw material to the discharge port 35, and then it falls into the grinding roller 1 from the discharge port 35. The upper end of the grinding roller 1 is fixedly connected to the lower end of the cylinder shell 31 by the support frame 12. The support frame 12 supports the cylinder shell 31 so that the cylinder shell 31 remains fixed and does not rotate with the grinding roller 1.

[0020] exist Figure 1 and Figure 3In the process, the slurry preparation mechanism 5 includes an inner cylinder 51. One end of the inner cylinder 51 is fixedly connected to a bearing seat 59, and the other end of the inner cylinder 51 is connected to a support pipe 511. One end of the support pipe 511 is connected to a water pipe 54 through a rotary joint 53. On the outside of the support pipe 511, from left to right, a shaft seal 57 and a pulley assembly 56 are installed sequentially. One end of the pulley assembly 56 is equipped with a motor 52. Several protruding columns 58 are staggered on the inner cylinder 51. Each protruding column 58 has a water-permeable hole that communicates with the inner cylinder 51, connecting one end of the water pipe 54 to an external pure water source. Connected to each other, pure water enters the inner cylinder 51 sequentially from the water pipe 54 and the support pipe 511, then flows out from the water-permeable hole on the protruding column 58 and enters the grinding roller 1. It mixes with the rare earth polishing powder raw material inside the grinding roller 1 to adjust the uniformity of the rare earth polishing powder particle size, increase the specific surface area of ​​the powder, and make subsequent reaction processes more complete. The inner cylinder 51 is located inside the grinding roller 1, thus forming an annular space between the grinding roller 1 and the inner cylinder 51. When the grinding roller 1 rotates, the steel balls inside the grinding roller 1 tumble together with the grinding roller 1, which can reduce the impact of the steel balls tumbling out of the grinding roller 1. The steel ball falls directly to the bottom from a high position, reducing the impact force of the steel ball on the inside of the grinding roller 1; a bearing 510 is installed on the inner side of the bearing seat 59, and the bearing seat 59 is rotatably connected to the support shaft 36 through the bearing 510. The support shaft 36 supports one end of the inner cylinder 51, allowing the inner cylinder 51 to rotate stably around the support shaft 36; the support tube 511 is rotatably connected to the grinding roller 1 through the shaft seal 57, thus ensuring that the support tube 511 and the grinding roller 1 rotate relative to each other; the upper end of the base 10 is fixedly connected to the lower end of the motor 52 with the support frame 6. The motor 52 can be kept stable by the support frame 6; a support block 55 is fixedly connected to the water pipe 54, and one end of the support block 55 is fixed to the support frame 6, so that the water pipe 54 and the support block 55 are kept stable. When the motor 52 drives the support pipe 511 to rotate through the pulley group 56, the support pipe 511 and the water pipe 54 rotate at the rotary joint 53, while the water pipe 54 remains stationary; when the protruding column 58 rotates together with the inner cylinder 51, the steel balls and rare earth polishing powder in the grinding roller 1 can be dispersed by the protruding column 58, which improves the grinding effect.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
