Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-purity alumina ball milling technology, specifically a device for high-purity alumina ball milling. Background Technology
[0002] High-purity alumina is an alumina material with extremely high purity, typically greater than 99.99%, exhibiting uniform particle size and stable chemical properties. Its main component is aluminum oxide, with a molecular weight of 102, and it appears as a white, odorless powder. Due to its excellent properties, such as high hardness, high strength, wear resistance, corrosion resistance, high temperature resistance, oxidation resistance, and good insulation, high-purity alumina is widely used in many high-tech industries. A high-purity alumina ball mill uses high-purity alumina as milling media in a ball mill for the process of pulverizing and grinding materials.
[0003] In existing ball mills, the object to be milled is usually placed into the grinding cylinder first, and then the grinding cylinder is installed and the grinding begins. However, when there are many objects to be milled and they are placed into the grinding cylinder, the internal space of the grinding cylinder is reduced, which prevents the grinding balls from moving freely at the beginning, resulting in slow grinding efficiency. Alternatively, the grinding can be performed in multiple stages, but the problem of slow efficiency still exists. Utility Model Content
[0004] The purpose of this invention is to provide a device for high-purity alumina ball milling to solve the problems mentioned in the background art.

A first cylinder cover and a second cylinder cover are respectively mounted on the outer sides of the grinding cylinder. A baffle mesh is mounted inside the grinding cylinder facing the first cylinder cover. A hexagonal opening is provided on the outer side of the first cylinder cover. A hexagonal bolt is mounted on the motor drive shaft. The hexagonal opening and the hexagonal bolt are slidably connected. A support assembly is provided on the inner side of the upper part of the base to support the grinding cylinder. An installation port is provided on the inner side of the second cylinder cover.

[0024] Please refer to Figures 1-5This utility model discloses a high-purity alumina ball milling device. This device is a small ball milling device used in the laboratory for ball milling high-purity alumina or other objects. It includes a base 1 and a ball milling cylinder 2. The base 1 is the bottom structure of the device, used for supporting and installing the overall structure. The ball milling cylinder 2 is the main structure of the device, and grinding balls made of high-purity alumina are placed inside. A first cylinder cover 21 and a second cylinder cover 22 are respectively provided on the outer sides of the ball milling cylinder 2. External threads 23 are provided on the outer walls of both sides of the ball milling cylinder 2. Internal threads 24 are provided on the inner walls of the first cylinder cover 21 and the second cylinder cover 22. The internal threads 24 and the external threads 23 are threadedly connected, that is, the first cylinder cover 21 and the second cylinder cover 22 are both threadedly connected to both sides of the ball milling cylinder 2. A blocking mesh 25 is provided inside the ball milling cylinder 2 facing the first cylinder cover 21. That is, when the high-purity alumina is poured out by opening the first cylinder cover 21 after the grinding is completed, the grinding balls will not be poured out, making it more convenient to use.
[0025] A motor 11 is installed on one side above the base 1. A hexagonal notch 15 is provided on the outer side of the first cylinder cover 21. A hexagonal bolt 12 is provided on the drive shaft of the motor 11. The hexagonal notch 15 and the hexagonal bolt 12 are slidably connected. A support assembly is provided on the inner side above the base 1. The support assembly is used to support the ball mill cylinder 2. The support assembly includes two support rods 3. A support tube 33 is movably provided on the outer side of the support rods 3. When installing the ball mill cylinder 2, it is placed on the ball mill cylinder 2, and the hexagonal notch 15 is connected to the hexagonal bolt 12 and inserted, thereby driving the motor 11. The ball mill cylinder 2 rotates to grind the internal objects. The rotation direction of the motor 11 is the same as the threaded installation direction of the two cylinder covers. The support rod 3 has first shaft grooves 31 on both sides of the ball mill cylinder 2. First ball bearings 32 are provided on the outside of the first shaft grooves 31. The first ball bearings 32 support the support tube 33. The support rod 3 does not directly contact the support tube 33. Instead, the support rod 3 rotates smoothly by the first ball bearings 32 rolling on the first shaft grooves 31, thereby reducing friction with the ball mill cylinder 2.
[0026] The inner side of the second cylinder cover 22 is provided with an installation port 44, which is an installation structure. A feeding assembly is provided on the outer side of the installation port 44 for continuous feeding. The feeding assembly includes a feeding pipe 4 and a baffle 5. A connecting pipe 41 is provided at the top of the feeding pipe 4, and the connecting pipe 41 is movably installed in the installation port 44. A second shaft groove 42 is provided on the outer side of the connecting pipe 41 and the inner side of the installation port 44. A second ball bearing 43 is provided inside the second shaft groove 42, which provides support for the connecting pipe 41. The connecting pipe 41 does not directly contact the installation port 44. An electric push rod 13 is provided on the other side above the base 1. A fixing part 14 is provided on the electric push rod 13. The fixing part 14 is connected to the outside of the feeding pipe 4. After the ball mill cylinder 2 is installed, the feeding pipe 4 is adjusted to the top, and the fixing part 14 is pushed by the electric push rod 13 to fix the position of the feeding pipe 4 and the ball mill cylinder 2. That is, when the ball mill cylinder 2 rotates, the mounting port 44 rotates outside the connecting pipe 41 and the second ball 43 rolls on the second shaft groove 42 to reduce friction. The feeding pipe 4 is always in the top position, so that feeding can be carried out continuously.
[0027] The top of the feeding pipe 4 has an installation port 44 on one side, and the cover 5 has a connecting bolt 51 on one side. The connecting bolt 51 is movably connected to the installation port 44, so that the cover 5 is connected to the top of the feeding pipe 4 and can move, thereby opening and closing the feeding pipe 4. The cover 5 has a sealing ring 52 on the inside. The other side of the top of the feeding pipe 4 has an iron block 45, and the other side of the cover 5 has a magnetic block 53. The magnetic block 53 is magnetically connected to the iron block 45, that is, the iron block 45 is connected by the magnetic block 53, so that the cover 5 closes the feeding pipe 4 and is sealed by the sealing ring 52.
[0028] The working principle of this utility model is as follows: By opening the second cylinder cover 22, the object to be ball-milled is placed inside the ball mill cylinder 2. During installation, the ball mill cylinder 2 is placed on top, and the hexagonal opening 15 is aligned with the hexagonal bolt 12 and inserted. The motor 11 then drives the ball mill cylinder 2 to rotate, thus ball-milling the internal object. After the ball mill cylinder 2 is installed, the feeding pipe 4 is adjusted to the top, and the fixing member 14 is pushed by the electric push rod 13, thereby fixing the position of the feeding pipe 4 and the ball mill cylinder 2. That is, when the ball mill cylinder 2 rotates, the mounting opening 44 is... The outer side of the connecting pipe 41 rotates, and the second ball 43 rolls on the second shaft groove 42, thereby reducing friction. The feeding pipe 4 remains above, so that feeding can be carried out continuously. A portion of the grinding material can be placed in the grinding cylinder 2 first. When the grinding material is ground to a certain extent, the internal space of the grinding cylinder 2 will increase, so that more grinding material can be added from the feeding pipe 4, thereby increasing the grinding efficiency. After the grinding material is finished, the high-purity alumina can be poured out by opening the first cylinder cover 21 without pouring out the grinding balls, making it more convenient to use.
