Description

Technical Field

[0001] This utility model relates to the field of rare earth processing technology, and in particular to a polishing powder ball mill. Background Technology

[0002] Rare earth polishing powder is a special powder material used for precision polishing and grinding. It is widely used in high-end manufacturing industries such as optics, semiconductors, and liquid crystal displays. Especially in the polishing process of crystals, glass, and ceramic materials, efficient and uniform ball milling is required to produce high-quality rare earth polishing powder. As a key piece of equipment in the production of rare earth polishing powder, the ball mill is crucial for improving the particle size uniformity, distribution, fineness, and surface properties of the powder.

[0003] However, existing polishing powder ball mills lack a screening structure when discharging rare earth polishing powder after grinding. This results in the grinding balls and polishing powder mixing together during the discharge process. This lack of separation means that the grinding balls and polishing powder are not effectively separated during discharge, and they flow out together, creating significant difficulties in subsequent processing. To separate the grinding balls from the polishing powder, workers have to manually screen and pick them. This process is not only very time-consuming, but also involves a huge amount of manual work due to the large number of grinding balls, severely impacting production efficiency and increasing labor costs.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] Example 1, please refer to Figures 1 to 4 This utility model provides a technical solution: a polishing powder ball mill, including a base plate 1, a screening box 101 fixedly installed on the top side of the inside of the base plate 1, a ball mill body 102 arranged on the top side of the inside of the screening box 101, a sieve plate 104 movably embedded in the inside of the screening box 101 near the bottom, sliding grooves 103 are opened on both sides of the inner wall of the screening box 101, the outer surfaces of both sides of the sieve plate 104 are slidably connected to the inner surface of the sliding grooves 103, telescopic rods 105 are fixedly installed around the bottom of the sieve plate 104, and return springs 106 are fixedly installed around the bottom of the sieve plate 104. The inner surfaces of the four return springs 106 are movably sleeved on the outer surfaces of the telescopic rods 105, and the other ends of the four return springs 106 and the four telescopic rods 105 are fixedly connected. The first rotating rod 107 is fixedly installed inside the screening box 101. The first motor 108 is fixedly installed on the left side of the first rotating rod 107. The bottom of the first motor 108 is fixedly installed on the left side of the screening box 101. An eccentric wheel 109 is fixedly sleeved on the outer surface of the first rotating rod 107. The first discharge pipe 110 is fixedly installed at the bottom of the screening box 101. A cover plate 112 is movably installed on the right side of the screening box 101. A collection box 111 is provided on the top of the bottom plate 1. Support members 2 are fixedly installed on both sides of the screening box 101. The outer surface of the ball mill body 102 is movably embedded in the two support members 2. A feed pipe 201 is fixedly installed on the left side of the ball mill body 102.

[0031] In this embodiment, after the ball mill body 102 has finished grinding the material, the operator can activate the solenoid valve 207 through the power supply system of the solenoid valve 207, thereby opening the second discharge pipe 206. This allows the material and grinding balls inside the ball mill body 102 to fall onto the top of the screen plate 104 through the second discharge pipe 206. Then, the operator can activate the first motor 108 through the power supply system of the first motor 108. During operation, the first motor 108 will drive the first rotating rod 107 to rotate through the output shaft. The first rotating rod 107 will then drive the eccentric wheel 109 to rotate in a circle. When the eccentric wheel 109 reaches the top of its circular rotation, it will push the screen plate 104 to slide upward through the slide groove 103 and pull the telescopic rod 105 and the return spring 106 to extend. When the eccentric wheel 109 reaches the bottom of its circular rotation, it will cause the return spring to extend. Spring 106 retracts with telescopic rod 105, simultaneously pulling screen plate 104 downwards. This, in turn, allows eccentric wheel 109 to reciprocate, causing screen plate 104 to perform a reciprocating lifting motion, thus screening the material. The material falls through screen plate 104 into the first discharge pipe 110 and is transported through the pipe to the collection box 111 on the bottom plate 1. The grinding balls remain on top of screen plate 104, allowing personnel to open cover 112 to collect them. The structure of screen plate 104 and eccentric wheel 109 effectively separates the grinding balls from the ground material through the reciprocating lifting motion. This automated separation reduces manual intervention and improves efficiency.

[0032] Example 2, as Figures 1 to 4 As shown, the outer surface of the feed pipe 201 is movably embedded in the left side of the screen box 101. A second rotating rod 203 is fixedly installed on the right side of the ball mill body 102. A one-way valve 202 is installed inside the feed pipe 201. The outer surface of the second rotating rod 203 is movably embedded in the right side of the screen box 101. A second motor 204 is fixedly installed on the right side of the second rotating rod 203. A flow guide plate 205 is fixedly installed on both sides of the inner wall of the ball mill body 102. The bottom of the second motor 204 is fixedly installed on the right side of the screen box 101. A second discharge pipe 206 is fixedly installed at the bottom of the ball mill body 102. A solenoid valve 207 is installed inside the second discharge pipe 206.

[0033] In this embodiment, personnel can open the one-way valve 202 to feed the material and grinding balls into the ball mill body 102 through the feed pipe 201, and then close the one-way valve 202. The second motor 204 on the screening box 101 is then started via its power supply system, enabling it to drive the second rotating rod 203 through its output shaft. The second rotating rod 203 then drives the ball mill body 102 to rotate inside the support member 2, thereby grinding the material inside. After grinding is complete, personnel can activate the solenoid valve 207 and open the second discharge pipe 206, allowing the material inside the ball mill body 102 to discharge. The material can flow into the interior of the second discharge pipe 206 through the guide plate 205, and be transported through the second discharge pipe 206 to fall onto the top of the screen plate 104. Through the structure of the support member 2 and the guide plate 205, the support member 2 can provide stable support for the ball mill body 102, preventing imbalance during the grinding process and affecting the grinding effect. At the same time, the guide plate 205 guides the material into the second discharge pipe 206, and then the second discharge pipe 206 transports the material to the top of the screen plate 104. This design ensures the high efficiency of material flow and helps the material flowability during the screening process.

[0034] Working Principle: During operation, after the ball mill body 102 has finished grinding the material, the operator can activate the solenoid valve 207 via its power supply system. This opens the second discharge pipe 206, allowing the material and grinding balls inside the ball mill body 102 to fall onto the top of the screen plate 104 through the second discharge pipe 206. Then, the operator activates the first motor 108 via its power supply system. During operation, the first motor 108 drives the first rotating rod 107 to rotate via its output shaft. The first rotating rod 107 then drives the eccentric wheel 109 to rotate in a circle. When the eccentric wheel 109 reaches the top of its rotation, it pushes the screen plate 104 upwards through the slide groove 103, pulling the telescopic rod 105 and the return spring 106 to extend. When the eccentric wheel 109 reaches the bottom of its rotation, it causes the screen plate 104 to return to its original position. When the spring 106 and the telescopic rod 105 retract, the screen plate 104 slides downward. This, in turn, causes the eccentric wheel 109 to reciprocate, raising and lowering the screen plate 104, thus screening the material. The material falls through the screen plate 104 into the first discharge pipe 110 and is transported through it to the collection box 111 on the bottom plate 1. The grinding balls remain on top of the screen plate 104, allowing personnel to open the cover 112 and collect them. The structure of the screen plate 104 and the eccentric wheel 109 effectively separates the grinding balls from the ground material through the reciprocating lifting motion. This automated separation reduces manual intervention and improves efficiency. In operation, personnel can open the one-way valve 202 to feed the material and grinding balls into the ball mill body 102 through the feed pipe 201, and then close the one-way valve 202. The second motor 204 on the screening box 101 is then started via its power supply system, enabling it to drive the second rotating rod 203 through its output shaft. The second rotating rod 203 then drives the ball mill body 102 to rotate inside the support member 2, thereby grinding the material inside. After grinding is complete, personnel can activate the solenoid valve 207 and open the second discharge pipe 206, allowing the material inside the ball mill body 102 to discharge. The material can flow into the interior of the second discharge pipe 206 through the guide plate 205, and be transported through the second discharge pipe 206 to fall onto the top of the screen plate 104. Through the structure of the support member 2 and the guide plate 205, the support member 2 can provide stable support for the ball mill body 102, preventing imbalance during the grinding process and affecting the grinding effect. At the same time, the guide plate 205 guides the material into the second discharge pipe 206, and then the second discharge pipe 206 transports the material to the top of the screen plate 104. This design ensures the high efficiency of material flow and helps the material flowability during the screening process.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
