Description

Technical Field

[0001] This utility model relates to the field of crystal growth technology, specifically to a crystal growth raw material grinding and mixing device. Background Technology

[0002] In the crystal growth process, the purity, particle size distribution, and mixing uniformity of the raw materials have a significant impact on the quality and performance of the crystal. Traditional grinding and mixing methods often suffer from problems such as insufficient grinding and uneven mixing, which lead to defects in the crystal growth process and affect the electrical, optical, and mechanical properties of the crystal. Therefore, it is of great significance to develop a new type of crystal growth raw material grinding and mixing device.

[0003] According to CN219804726U, a crystal growth raw material grinding and mixing device includes a machine body and a ball mill mixing tank mounted on the machine body. The machine body includes a frame, several threaded rollers, several rubber rollers, and a servo motor mounted on the frame. The threaded rollers and rubber rollers are arranged alternately from front to back and are rotatably mounted on the frame via bearings. The servo motor is connected to one of the threaded rollers and drives it to rotate alternately in both forward and reverse directions. A transmission unit is provided on the threaded rollers and rubber rollers. The servo motor drives the threaded rollers to rotate, and the transmission unit drives the rotation of each threaded roller and each rubber roller. Synchronous rotation; the outer wall of the ball mill mixing tank is provided with concave and convex ring patterns that engage with the threaded rollers. The cooling jacket of the ball mill mixing tank facilitates the filling of coolant, which can effectively reduce the temperature in the tank liner. This allows the temperature of the raw materials in the tank liner to be effectively controlled during the grinding and mixing process, maintaining the characteristics of the raw materials and improving the quality of the crystals. As can be seen from the above, although this device can be applied well, the raw materials are usually ground and mixed in a closed space, requiring the cooling liquid to cool the ground raw materials. This makes the device somewhat inconvenient for grinding and mixing raw materials and needs to be improved. Utility Model Content

[0023] In use, the abutment strip 26 is provided to fix the grinding frame 10 to the top of the support table 9.

[0024] A grinding frame 10 is installed on the top of the bearing platform 9. Guide seats 11 are provided on the inner walls of both sides of the grinding frame 10.

A guide post 13 is provided at the center of the top of the base plate 12. A lifting seat 16 is movably installed on the outer wall of the upper end of the guide post 13. A second lead screw 15 is threaded on one side inside the lifting seat 16. Both ends of the second lead screw 15 extend to the outside of the lifting seat 16.

[0025] In use, the second lead screw 15 is used to position the lifting seat 16.

[0026] A second rotary drive component 14 is provided on one side of the top of the chassis 12, and the top of the second rotary drive component 14 is connected to the bottom of the second lead screw 15.

[0027] In use, the second rotary drive 14 is configured to drive the second lead screw 15 to rotate;

[0028] The lifting seat 16 is provided with a lifting frame 17 at the end away from the guide column 13. A telescopic drive component 18 is installed on one side of the bottom end of the lifting frame 17 through a bracket. One end of the telescopic drive component 18 is connected to the outer wall of the linkage frame 19.

[0029] In use, the telescopic drive component 18 is used to drive the linkage frame 19 to move horizontally.

[0030] The bottom end of the lifting frame 17 is provided with a limiting rail 24, and the bottom end of the limiting rail 24 is slidably connected to a linkage frame 19. A component seat 20 is provided on the outer wall of one side of the linkage frame 19, and a third belt drive mechanism 22 is provided on the inner wall of the component seat 20. A grinding roller 23 is installed on the inner wall of the lower end of the third belt drive mechanism 22.

[0031] In use, the grinding roller 23 is set to grind the raw materials.

[0032] A third rotary drive 21 is installed on the outer wall of the mounting base 20. One end of the third rotary drive 21 extends to the inner side of the mounting base 20 and is connected to the upper end of the third belt drive mechanism 22.

[0033] In use, the third rotary drive 21 is configured to drive the third belt drive mechanism 22 to operate.

[0034] In this embodiment, various raw materials are first fed into the grinding frame 10. When the rotating grinding roller 23 moves down and contacts the raw materials inside the grinding frame 10, the raw materials can be ground and mixed in an open manner, allowing for natural heat dissipation and cooling. The second rotary drive 14 drives the second lead screw 15 to rotate, causing the lifting seat 16 to slide on the outer wall of the second lead screw 15 and the guide column 13. This allows the lifting frame 17 and other related components to drive the grinding roller 23 to rise and fall. When the third rotary drive 21 is activated, the grinding roller 23 can be raised and lowered via the second rotary drive 14. The three-belt drive mechanism 22 drives the grinding roller 23 to rotate, so that the grinding roller 23 grinds the raw material. Then, the first rotary drive member 2 drives the first belt drive mechanism 3 and the second belt drive mechanism 4 to operate, so that the first belt drive mechanism 3 and the second belt drive mechanism 4 drive the first lead screw 5 to rotate, so that the nut seat 7 slides on the outer wall of the first lead screw 5 and the guide rod 6, and the nut seat 7 drives the grinding frame 10 to move back and forth through the linkage seat 8. Then, the telescopic drive member 18 drives the linkage frame 19 to be located on the limit rail 24. By sliding the bottom of the grinding frame 10, the grinding roller 23 can be driven to move left and right, thus facilitating the grinding roller 23 to grind and mix the raw material inside the grinding frame 10 in all directions. Finally, by tightening the threaded pin 27 and rotating the abutment strip 26, the bottom of the abutment strip 26 is no longer in contact with the bottom of the grinding frame 10, allowing the grinding frame 10 to be detached from the top of the support platform 9. When the threaded pin 27 is tightened, one end of the abutment strip 26 abuts against the bottom of the grinding frame 10, thus fixing the grinding frame 10 to the top of the support platform 9. This facilitates the assembly and disassembly of the grinding frame 10. This facilitates the cleaning and maintenance of the grinding frame 10. Furthermore, two guide seats 11 are positioned on either side of the bottom of the grinding frame 10. The curvature of the guide seats 11 is designed to fit the grinding roller 23, allowing the grinding roller 23 to fully contact the raw material inside the grinding frame 10. This facilitates efficient grinding of the raw material by the grinding roller 23. During the grinding process, various ground raw materials combine together, and the moving grinding roller 23 pushes different types of raw materials together to perform mixing operations, thus completing the use of this grinding and mixing device.
