Description

Technical Field

[0001] This utility model relates to the field of aluminum powder refining technology, and in particular to an alumina powder refining device. Background Technology

[0002] Alumina powder for lithium battery separators is a white micro-powder with uniform particle size, easy dispersion, stable chemical properties, moderate high-temperature shrinkage, good sintering performance, and conversion rate. It is a basic raw material for producing heat-resistant, wear-resistant, and corrosion-resistant products. Refining alumina powder can enhance the heat resistance of the separator, improve its mechanical strength, improve lithium-ion conductivity, and improve the electrochemical performance of the battery. In addition, it can also provide good isolation, ensure efficient charging and discharging of the battery, and improve the battery's charging and discharging performance.

[0003] Existing alumina powder refining devices generally employ dry mechanical ball milling during the refining process. The refining is achieved through the grinding action of the ball mill. However, due to the impact and friction of the grinding balls on the material in the ball mill, the refining efficiency is low, the refining time is long, and the refined alumina powder has an uneven particle size, thus reducing the overall refining effect.

[0004] Therefore, it is necessary to provide an alumina powder refining device to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides an alumina powder refining device, which solves the problems in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides an alumina powder refining device, comprising a device body, a refining frame installed inside the device body via a connecting rod, a first filter hole formed on the periphery of the refining frame, a first refining cavity formed on the top surface of the refining frame, a second filter hole formed on the inner wall of the first refining cavity, a sealing cover provided on the top surface of the device body, a drive motor provided on the top surface of the sealing cover, a main shaft provided through the output end of the drive motor on the top surface of the sealing cover, a first grinding ball provided at the bottom end of the main shaft, a grinding column provided at the bottom end of the first grinding ball, and grinding protrusions provided around the grinding column. By configuring the refining frame, the main shaft, and the first grinding ball... The combined use of the first refining chamber, the second filter hole, the grinding column, and the grinding protrusions facilitates two-stage grinding and refining of alumina. During operation, the operator feeds the alumina powder to be processed into the first refining chamber through the feed inlet, then starts the drive motor. The drive motor then drives the first grinding ball and the grinding column to rotate via the main shaft. The first grinding ball grinds the alumina powder above the first refining chamber, while the grinding protrusions on the periphery of the grinding column grind and refine the alumina powder at the bottom of the first refining chamber. The alumina powder refined through these two stages is then discharged through the second filter hole for further processing. This method is simple to operate and facilitates multi-stage refining of alumina powder.

[0007] Preferably, a second refining cavity is formed near the edge of the bottom surface of the refining frame. The second refining cavity is connected to the first refining cavity through a second filter hole. A bottom cover is provided at the bottom of the second refining cavity. A second grinding ball is placed inside the second refining cavity. A drive rod is provided on the outer surface of the main shaft. One end of the drive rod extends into the second refining cavity. By using the second refining cavity, drive rod, second grinding ball, and first filter hole in combination, it is convenient to improve the multi-stage refining treatment of alumina powder. During operation, the alumina powder in the first refining cavity enters the second refining cavity through the second filter hole. Then, under the action of the main shaft, the drive rod is driven to rotate inside the second refining cavity. When the drive rod rotates, it pushes the second grinding ball to roll inside the second refining cavity, thus refining the alumina powder inside the second refining cavity. After the treatment is completed, it is discharged through the first filter hole. This method is simple to operate, facilitates multi-stage refining treatment of alumina powder, and improves its refining accuracy.

[0008] Preferably, the inner diameter of the first filter hole is smaller than the inner diameter of the second filter hole.

[0009] Preferably, the top surface of the refining frame is provided with an annular slide, which is connected to the second refining cavity. The inner width of the annular slide is smaller than the diameter of the second grinding ball. By setting the annular slide, it is convenient to make way for the rotation of the drive rod. By setting the inner width of the annular slide to be smaller than the diameter of the second grinding ball, the second grinding ball is prevented from flying out of the annular slide.

[0010] Preferably, the top surface of the sealing cover is provided with a feed inlet, which is located directly above the first refining chamber. By providing the feed inlet, it is convenient to add alumina powder.

[0011] Preferably, the device body is provided with a conical hopper at the bottom end, and a discharge pipe is provided at the bottom end of the conical hopper. A solenoid valve is installed on the surface of the discharge pipe. By providing a discharge pipe, it is convenient to discharge the finely refined alumina powder inside. By providing a solenoid valve, it is convenient to control the discharge pipe.

[0012] Preferably, a support base is installed at the bottom of the device body, and a controller is installed on the support base. The support base facilitates the support of the device body, and the controller facilitates the control of the electrical components inside the device body.

[0014] Compared with existing technologies, the alumina powder refining device, through the coordinated use of a refining frame, main shaft, first grinding balls, first refining chamber, second filter, grinding column, and grinding protrusions, facilitates two-stage grinding and refining of alumina. During operation, the operator feeds the alumina powder to be processed into the first refining chamber through the inlet, then starts the drive motor. The drive motor then rotates the first grinding balls and grinding column via the main shaft. The first grinding balls grind the alumina powder above the first refining chamber, while the grinding protrusions on the periphery of the grinding column grind and refine the alumina powder at the bottom of the first refining chamber. The alumina powder refined through these two stages is discharged through the second filter for further processing. This method is simple to operate and facilitates multi-stage refining of alumina powder. Furthermore, the coordinated use of a second refining chamber, a drive rod, a second grinding ball, and a first filter hole enhances the multi-stage refining of alumina powder. During operation, alumina powder from the first refining chamber enters the second refining chamber through the second filter hole. Then, under the action of the spindle, the drive rod rotates within the second refining chamber. As the drive rod rotates, it pushes the second grinding ball to roll within the chamber, thus refining the alumina powder. After processing, the powder is discharged through the first filter hole. This method is simple to operate, facilitates multi-stage refining of alumina powder, and improves its refining accuracy.

This method is simple to operate and facilitates multi-stage refining of alumina powder.

[0026] The working principle of the alumina powder refining device provided by this utility model is as follows:

[0027] In operation, the alumina powder refining device involves feeding the alumina powder to be processed into the first refining chamber 16 through the feed inlet. The drive motor 3 is then started, which, via the main shaft 8, drives the first grinding balls 17 and the grinding column 19 to rotate. The first grinding balls 17 grind the alumina powder above the first refining chamber 16, while the grinding protrusions 20 on the periphery of the grinding column 19 grind the alumina powder at the bottom of the first refining chamber 16. The alumina powder refined through these two stages of grinding is then discharged through the second filter 18 for further processing. This method is simple to operate and facilitates multi-stage refining of alumina powder. This is achieved by setting up a second refining chamber 14 and a drive motor 19. The coordinated use of the moving rod 15, the second grinding ball 13, and the first filter hole 12 facilitates the multi-stage refining of alumina powder. During operation, the alumina powder inside the first refining chamber 16 enters the second refining chamber 14 through the second filter hole 18. Then, under the action of the main shaft 8, the driving rod 15 is driven to rotate inside the second refining chamber 14. When the driving rod 15 rotates, it pushes the second grinding ball 13 to roll inside the second refining chamber 14, thus refining the alumina powder inside the second refining chamber 14. After the processing is completed, the powder is discharged through the first filter hole 12.
