Description

Technical Field

[0001] This utility model relates to the field of wet ball milling technology, specifically a grinding and dispersing mechanism for wet ball milling of alumina powder. Background Technology

[0002] Alumina powder is an important inorganic material, widely used in various fields due to its excellent physicochemical properties. The processing of alumina powder requires a wet ball mill to grind lumpy alumina into powder. The wet ball mill is a key piece of equipment for further pulverizing materials after they have been crushed. In dry ball milling, alumina powder is prone to agglomeration due to electrostatics or van der Waals forces, resulting in uneven particle distribution. The liquid medium in wet ball milling, such as water or organic solvents, can effectively disperse particles, reduce agglomeration, and make the particle distribution more uniform. A ball mill consists of a cylinder, hollow inlet and outlet shafts, and grinding heads. The cylinder is a long cylindrical shape, containing grinding media. The cylinder is made of steel plate and fixed with steel liners. The grinding media are generally steel spheres, loaded into the cylinder in different diameters and proportions, and move to perform the ball milling process.

[0003] In existing wet ball milling of alumina powder, the grinding and dispersing mechanism often uses a single shaft for input, which drives the cylinder to rotate. However, the cylinder only has a self-rotation process, resulting in a single movement trajectory and path of the raw material and the ball mill body. This leads to the problem of raw material settling to the bottom during the grinding process, which affects the grinding efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a grinding and dispersing mechanism for wet ball milling of alumina powder, in order to solve the problem mentioned in the background art that the existing grinding and dispersing mechanisms for wet ball milling of alumina powder often use a single shaft for input to drive the cylinder to rotate. However, the cylinder only has a self-rotation process, which results in the material and the ball mill body having a single movement trajectory and path, causing the material to settle to the bottom during the grinding process, thus affecting the grinding efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding and dispersing mechanism for wet ball milling of alumina powder, comprising a base and a grinding section:

[0016] Preferably, the grinding part also has a transmission gear a disposed on the outside of the rotating shaft b, and a motor is fixedly mounted on the top of the base by bolts. The output end of the motor is provided with a transmission gear b, which meshes with the transmission gear a.

[0017] By adopting the above technical solution, the transmission gear b can be driven to rotate by the motor, thereby driving the transmission gear a to rotate.

[0018] Preferably, the rotation axis of the transmission gear a coincides with the rotation axis of the rotating shaft a.

[0019] By adopting the above technical solution, the rotation of the transmission gear a can drive the entire rotating frame to rotate.

[0020] Compared with the prior art, the beneficial effects of this utility model are: by providing a grinding part, the grinding barrel can be driven to revolve around the rotation axis of the rotating frame at a certain angle by the rotation of the rotating frame.

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.

[0028] Example 1

[0029] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a grinding and dispersing mechanism for wet ball milling of alumina powder, comprising a base 1 and a grinding section 2.

[0030] A support frame a101 is mounted on the top of the base 1, and a support frame b103 is also mounted on the top of the base 1. A bevel gear a105 is bolted to the side of the support frame b103. The grinding part 2 is mounted on the top of the base 1. A rotating frame 201 is horizontally rotatably mounted on the top of the support frame a101. The end of the rotating frame 201 away from the support frame a101 is rotatably connected to the support frame b103. A grinding barrel 205 is rotatably mounted inside the rotating frame 201. The grinding barrel 205 has an inclination angle, and a feeding port 207 is provided at one end of the grinding barrel 205. The principle of wet ball milling is that the grinding media, materials, and liquids are placed together in the grinding barrel 205, and the grinding is carried out by the grinding barrel 205. The rotation of the 05 unit grinds the material. The feeding port 207 is equipped with a flip cover with a locking device. A bevel gear b206 is provided on the outer side of the feeding port 207. The bevel gear b206 meshes with the bevel gear a105. The rotation of the rotating frame 201 drives the grinding barrel 205 to revolve around the rotation axis of the rotating frame 201, so that the bevel gear a105 drives the grinding barrel 205 to rotate on its own axis. Through the rotation of the rotating frame 201, the grinding barrel 205 is driven to revolve around the rotation axis of the rotating frame 201 with a certain angle. At the same time, the grinding barrel 205 is also driven by the bevel gear a105, thus rotating on its own axis inside the rotating frame 201.

[0031] Example 2

[0032] Please see Figure 3 , Figure 4 and Figure 5 This embodiment provides a technical solution: a grinding and dispersing mechanism for wet ball milling of alumina powder, comprising a grinding section 2, a rotating frame 201, and a grinding barrel 205.

[0033] A rotating groove a102 is formed inside the support frame a101. A rotating shaft b204 is provided at one end of the rotating frame 201 near the support frame a101. The rotating shaft b204 is embedded in the rotating groove a102 and rotatably connected to the support frame a101, allowing the rotating shaft b204 to rotate inside the support frame a101. A rotating groove b104 is formed inside the support frame b103. A rotating shaft a203 is provided at one end of the rotating frame 201 near the support frame b103. The grinding barrel 205 is rotatably connected to the support frame b103 within the rotating groove b104. The axis of the rotating shaft a203 coincides with that of the rotating shaft b204, allowing the rotating shaft a203 to rotate inside the support frame b103. A rotating groove c202 is provided inside the rotating frame 201, and the grinding barrel 205 is embedded in the rotating groove c202 and rotatably connected to the rotating frame 201. A feeding port 207 is provided at the end of the grinding barrel 205 away from the rotating frame 201, allowing the grinding barrel 205 to move within the rotating frame 201. The grinding barrel 205 rotates at an angle to the rotation axis of the rotating frame 201, allowing the grinding barrel 205 to revolve around the rotation axis of the rotating frame 201 at a certain angle. A transmission gear a208 is bolted to the outside of the rotating shaft b204. A motor 210 is bolted to the top of the base 1. A transmission gear b209 is mounted at the output end of the motor 210, meshing with the transmission gear a208. The motor 210 is a servo motor, and its working principle is based on a closed-loop control system. High-precision motion control is achieved by precisely controlling the position, speed, and torque of the servo motor. The motor 210 can drive the transmission gear b209 to rotate, thereby driving the transmission gear a208 to rotate. The rotation axis of the transmission gear a208 coincides with the rotation axis of the rotating shaft a203. The rotation of the transmission gear a208 can drive the entire rotating frame 201 to rotate.

[0034] Working principle: First, power on the device, then open the flap at the feeding port 207 and pour the alumina material into the grinding barrel 205. The motor 210 drives the transmission gear b209 to rotate, which in turn drives the transmission gear a208 to rotate, thereby causing the rotating frame 201 to rotate within the support frame a101 and support frame b103. Through the rotation of the rotating frame 201, the grinding barrel 205 revolves around the rotation axis of the rotating frame 201 at a certain angle. At the same time, the grinding barrel 205 is also driven by the bevel gear a105, thus rotating inside the rotating frame 201. This causes the grinding barrel 205 to continuously change its tilt angle during the grinding process, improving the grinding efficiency.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
