Description

Technical Field

[0001] This utility model relates to the field of ball milling equipment technology, specifically to a ball milling equipment for hafnium dioxide production. Background Technology

[0002] Hafnium dioxide (HfO2) is an oxide of hafnium, a white solid at room temperature and pressure. It is sparingly soluble in water, insoluble in hydrochloric acid and nitric acid, but soluble in concentrated sulfuric acid and hydrofluoric acid. It is chemically stable, possessing high melting point, high hardness, high dielectric constant, and wide bandgap, thus finding wide applications in various fields. During its production, the refinement and uniformity of the raw materials have a crucial impact on the performance of the final product.

[0003] However, in the traditional process of pulverizing hafnium dioxide using ball milling equipment for hafnium oxide production, the material tends to adhere to the cylinder wall of the ball mill, which reduces the collision frequency between the grinding balls and the material, resulting in excessively long grinding time and increased energy consumption. To address these issues, the inventors have proposed a ball milling device for hafnium dioxide production. Utility Model Content

[0004] In order to solve the problem of low grinding efficiency of traditional ball mill equipment for hafnium dioxide production, the purpose of this utility model is to provide a ball mill equipment for hafnium dioxide production.

[0007] Preferably, a synchronous pulley one is fixedly connected to one end of the servo motor drive end, a synchronous pulley two is fixedly connected to one side of the mounting bracket, the outer sides of the synchronous pulley one and the synchronous pulley two are connected by belt drive, a synchronous pulley four is coaxially connected to one side of the mounting bracket and the synchronous pulley two, and a synchronous pulley three is fixedly connected to one end of the rotating rod two to one side of the mounting bracket, the outer sides of the synchronous pulley three and the synchronous pulley four are connected by belt drive.

[0008] Preferably, the mounting plate has a base plate at its bottom end, and rubber pads are fixedly connected to the base plate at each of the four corners of the bottom end of the mounting plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-4 As shown, this utility model provides a ball milling device for hafnium dioxide production, including a mounting plate 1 and a ball mill 12. Two mounting brackets 2 are fixedly connected to the top of the mounting plate 1 near the ball mill 12. A fixing block 3 is fixedly connected to the top of each mounting bracket 2. Connecting rods 5, which are evenly distributed, are fixedly connected to the outer side of the fixing block 3. A hammer head 6 is fixedly connected to the end of each connecting rod 5 away from the rotating rod 4. The bottom end of the hammer head 6 is located above the ball mill 12. A rotating rod 7 is rotatably connected between the two mounting brackets 2. An eccentric wheel 8, which is evenly distributed, is fixedly connected to the outer side of the rotating rod 7. The position of the eccentric wheel 8 corresponds to that of the hammer head 6. A connecting block 9 is movably sleeved on the outer side of the eccentric wheel 8. A connecting seat 10 is fixedly connected to the outer side of the connecting rod 5. Two square blocks 11 are fixedly connected to the bottom end of the connecting seat 10. The top end of the connecting block 9 is rotatably connected between the two square blocks 11.

[0020] Vertical plates 13 are fixedly connected to both sides of the top of the mounting plate 1. The ball mill 12 is rotatably connected between the two vertical plates 13. A gear ring 14 is fixedly connected to the outer side of one end of the ball mill 12. A fixing plate 15 is fixedly connected to one side of the vertical plate 13. A servo motor 16 is fixedly installed on one side of the fixing plate 15. A gear 17 is fixedly connected to the drive end of the servo motor 16. The gear 17 meshes with the gear ring 14.

[0021] By adopting the above technical solution, the servo motor 16 drives the gear 17 to rotate, and the gear 17 meshes with the gear ring 14, thereby driving the ball mill 12 and the gear ring 14 to rotate, thus realizing the driving of the ball mill.

[0022] One end of the servo motor 16 is fixedly connected to a synchronous pulley 18, and one side of the mounting bracket 2 is fixedly connected to a synchronous pulley 19. The outer sides of the synchronous pulley 18 and the synchronous pulley 29 are connected by a belt drive. One side of the mounting bracket 2 is coaxially connected to the synchronous pulley 29 and a synchronous pulley 41. One end of the rotating rod 27 extends to one side of the mounting bracket 2 and is fixedly connected to a synchronous pulley 30. The outer sides of the synchronous pulley 30 and the synchronous pulley 41 are connected by a belt drive.

[0023] By adopting the above technical solution, when the first synchronous pulley 18 rotates, the outer sides of the first synchronous pulley 18 and the second synchronous pulley 19 are connected by a belt drive, which drives the second synchronous pulley 19 to rotate. The second synchronous pulley 19 and the fourth synchronous pulley 21 are coaxial, which drives the fourth synchronous pulley 21 to rotate. At the same time, the outer sides of the third synchronous pulley 20 and the fourth synchronous pulley 21 are connected by a belt drive, which drives the second rotating rod 7 to rotate, thereby driving the hammer head 6 to work.

[0024] A base plate 22 is provided at the bottom of the mounting plate 1, and rubber pads 23 are fixedly connected to the base plate 22 at the four corners of the bottom of the mounting plate 1.

[0025] By adopting the above technical solution and setting the rubber pad 23, the vibration and impact force generated during equipment operation can be effectively absorbed and dispersed, thereby protecting the equipment itself from damage caused by vibration and impact.

[0026] Each hammer head 6 has a rubber head 25 fixedly connected to its bottom end.

[0027] By adopting the above technical solution and setting the rubber head 25, the striking force is made more uniform while protecting the ball mill 12 from being damaged by the impact.

[0028] A reinforcing rib 24 is fixedly connected between one side of the bottom of the mounting bracket 2 and the top of the mounting plate 1.

[0029] By adopting the above technical solution and setting the reinforcing ribs 24, the stability of the connection between the mounting frame 2 and the mounting plate 1 can be enhanced.

[0030] Working principle: In hafnium dioxide production, when the ball mill 12 crushes the material, the servo motor 16 drives the gear 17 to rotate. The gear 17 meshes with the gear ring 14, simultaneously driving the ball mill 12 and the gear ring 14 to rotate, thus enabling the mounting plate 1 to work. Simultaneously, the servo motor 16 drives the synchronous pulley 18 to rotate. The synchronous pulley 18 is connected to the outer side of the synchronous pulley 19 via a belt drive, simultaneously driving the synchronous pulley 19 to rotate. Furthermore, the synchronous pulley 19 and the synchronous pulley 21 are coaxial, thereby driving the synchronous pulley 21 to rotate. 1. The rotating rod rotates, and the outer sides of the synchronous pulley 3 20 and synchronous pulley 4 21 are connected by a belt drive, thereby driving the rotating rod 2 7 and the eccentric wheel 8 to rotate. The eccentric wheel 8 and the connecting block 9 are engaged, and the rotating rod 1 4 limits one end of the connecting seat 10. When the eccentric wheel 8 rotates, it drives the hammer head 6 to swing vertically around the axis of the rotating rod 1 4, thereby realizing the hammering operation on the top of the mounting plate 1, shaking off the material adhering to the inner wall of the mounting plate 1, thereby increasing the impact frequency between the grinding ball and the material, and further improving the grinding efficiency of the material.

[0031] Furthermore, by setting rubber pads 23, the vibration and impact forces generated during equipment operation can be effectively absorbed and dispersed, thereby protecting the equipment itself from damage caused by vibration and impact.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
