Description

Technical Field

[0001] This utility model relates to the field of waste lithium battery processing technology, specifically a waste lithium battery electrode grinding device. Background Technology

[0002] Waste lithium battery electrode grinding equipment is a type of mechanical equipment specifically used for surface treatment of recycled or reused lithium-ion battery electrodes. It achieves this by grinding, polishing, and grinding the coating materials, binders, and conductive additives on the electrodes, thus removing surface contaminants, reducing electrode thickness variations, improving the consistency of capacity information per unit area, and enhancing the efficiency of subsequent separation, recycling, and reuse. Currently, waste lithium battery recycling technology requires disassembling the waste lithium batteries into different parts, followed by screening and crushing, and finally grinding for reuse. The indirect coordination between crushing and grinding increases the operational intervals and reduces overall efficiency. Integrated operation, on the other hand, is hampered by the one-piece molding structure, leading to difficulties in later maintenance and increasing the likelihood of equipment damage. Furthermore, static grinding techniques can easily cause waste lithium battery electrodes to accumulate during grinding, making grinding difficult and resulting in uneven grinding. This reduces the effectiveness of the waste lithium battery electrode grinding equipment and indirectly affects its grinding efficiency.

[0003] Therefore, it is necessary to develop a grinding equipment for waste lithium battery electrodes. Utility Model Content

[0004] The purpose of this invention is to provide a grinding equipment for waste lithium battery electrodes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste lithium battery electrode grinding equipment, including an operating frame, guide columns installed on both sides of the top of the operating frame, a grinding tank installed at the center of the top of the operating frame, a fixing ring A installed on the lower outer wall of the grinding tank, and electric telescopic rods installed on both sides of the bottom of the fixing ring A.

[0006] A grinding assembly is installed on the top of the grinding jar. The grinding assembly includes a sealing cover, and a retaining ring B is installed on the lower part of the outer wall of the sealing cover.

[0007] Preferably, a limit ring is installed at the top of the guide post, and a spring is installed on the lower part of the outer wall of the guide post.

[0008] Preferably, the outer wall of the grinding jar is slidably connected to the inside of the operating frame, and guide plates are installed on both sides of the top of the fixing ring A.

[0009] Preferably, the inner side of the guide plate is slidably connected to the outer wall of the guide column, and a vibrator is installed on the upper part of the outer wall of the grinding tank.

[0010] Preferably, the bottom of the fixing ring B is fixedly connected to the output end of the electric telescopic rod, and a filter frame is installed at the bottom of the sealing cover.

[0011] Preferably, the outer wall of the filter frame is slidably connected to the interior of the grinding tank, and a motor is installed at the top center of the sealing cover.

[0012] Preferably, a rotating shaft is installed at the output end of the motor, and blades are installed on the upper part of the outer wall of the rotating shaft.

[0013] Preferably, the blade is located inside the filter frame, and a grinding roller is installed at the bottom end of the rotating shaft, with the grinding roller located inside the grinding tank at the bottom.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By fixing the retaining ring B on the sealing cover to the output end of the electric telescopic rod on the grinding tank, and setting multiple sets of crushing blades on the outer wall of the rotating shaft inside the filter frame on the sealing cover, and setting the grinding roller on the bottom of the rotating shaft below the filter frame, the sealed cover in its sealed state allows waste lithium battery electrodes to be fed in. Once the waste lithium battery electrodes fall into the filter frame, the motor drives the rotating shaft to rotate at high speed, so that the blades crush the waste lithium battery electrodes. The crushed waste lithium battery electrodes then fall below the filter frame and are ground by the grinding roller, completing the grinding operation. The entire system integrates crushing and grinding, improving operational efficiency. After grinding is completed, when maintenance is required, simply drive the electric telescopic rod to raise the sealing cover to the specified height to clean the blockages in the filter frame mesh and clean the outer wall of the grinding roller below, reducing the chance of equipment damage.

[0016] During the grinding process, a vibrator and springs are used to vibrate the grinding tank at high speed. This vibration facilitates the crushing and grinding of waste lithium battery electrodes, ensuring uniformity and minimizing uneven grinding caused by static grinding. This effectively improves the performance of the waste lithium battery electrode grinding equipment and indirectly increases its grinding efficiency. Attached Figure Description

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.

[0023] This utility model provides the following technical solution: a grinding device for waste lithium battery electrodes. Please refer to [link / reference]. Figures 1-4 The system includes an operating frame 1, with guide posts 101 installed on both sides of the top of the operating frame 1. A limit ring 102 is installed at the top of each guide post 101, and a spring 103 is installed on the lower outer wall of each guide post 101. A grinding jar 2 is installed at the center of the top of the operating frame 1, with a fixing ring A201 installed on the lower outer wall of the grinding jar 2. Electric telescopic rods 202 are installed on both sides of the bottom of the fixing ring A201. The outer wall of the grinding jar 2 is slidably connected to the interior of the operating frame 1. Guide plates 203 are installed on both sides of the top of the fixing ring A201. The grinding tank 2 is slidably connected to the outer wall of the guide column 101 on one side. Vibrators 204 are installed on the upper part of the outer wall of the grinding tank 2. The guide plate 203 is welded and fixed on the upper part of the fixing ring A201 on the grinding tank 2. The guide plate 203 is slidably set on the outer wall of the guide column 101 on the operating frame 1. The spring 103 is fitted on the outer wall of the guide column 101. With the vibration of the vibrator 204 on the upper part of the outer wall of the grinding tank 2, the vibration generated by the vibrator 204 when it is powered on, combined with the elastic effect of the spring 103, can effectively vibrate the entire grinding tank 2.

[0024] A grinding assembly is installed on the top of the grinding tank 2. The grinding assembly includes a sealing cover 3. A fixing ring B301 is installed on the lower outer wall of the sealing cover 3. The bottom of the fixing ring B301 is fixedly connected to the output end of the electric telescopic rod 202. A filter frame 302 is installed at the bottom of the sealing cover 3. The outer wall of the filter frame 302 is slidably connected to the inside of the grinding tank 2. A motor 303 is installed at the center of the top of the sealing cover 3. A rotating shaft 304 is installed at the output end of the motor 303. Blades 305 are installed on the upper outer wall of the rotating shaft 304. The blades 305 are located inside the filter frame 302. A grinding roller 306 is installed at the bottom of the rotating shaft 304. The grinding roller 306 is located at the lower inside of the grinding tank 2. The fixing ring B301 on the sealing cover 3 is fixedly installed at the output end of the electric telescopic rod 202 on the grinding tank 2. Multiple sets of crushing blades 305 on the upper outer wall of the rotating shaft 304 are set on the sealing cover 3. Inside the filter frame 302, the grinding roller 306 on the bottom end of the rotating shaft 304 is positioned below the filter frame 302, allowing waste lithium battery electrodes to be placed into the sealed cover 3 in its sealed state. Once the waste lithium battery electrodes fall into the filter frame 302, the rotating shaft 304 is driven by the motor 303 to rotate at high speed, causing the blades 305 to crush the waste lithium battery electrodes. The crushed waste lithium battery electrodes then fall below the filter frame 302 and are further ground by the grinding roller 306, completing the grinding operation. The entire system integrates crushing and grinding, improving operational efficiency. After grinding is completed, when maintenance is required, the sealing cover 3 can be raised to a specified height by the electric telescopic rod 202 to clean the blockages in the mesh of the filter frame 302 and to clean the outer wall of the grinding roller 306 below, reducing the chance of equipment damage.

[0025] Working principle: When using this utility model, a guide plate 203 is welded and fixed above the fixing ring A201 on the grinding jar 2, and the guide plate 203 is slidably set on the outer wall of the guide column 101 on the operating frame 1. A spring 103 is fitted on the outer wall of the guide column 101, and a vibrator 204 is installed above the outer wall of the grinding jar 2. The vibration generated by the energized vibrator 204, combined with the elastic effect of the spring 103, can effectively vibrate the entire grinding jar 2. By fixing the fixed ring A201 on the sealing cover 3, the grinding jar 2 can be effectively vibrated. The fixed ring B301 is fixedly installed at the output end of the electric telescopic rod 202 on the grinding tank 2, and multiple sets of crushing blades 305 above the outer wall of the rotating shaft 304 are set inside the filter frame 302 on the sealing cover 3. The grinding roller 306 on the bottom end of the rotating shaft 304 is positioned below the filter frame 302, so that the sealing cover 3, in its sealed state, allows waste lithium battery electrodes to be added. Once the waste lithium battery electrodes fall into the filter frame 302, the motor 303 drives the rotating shaft 304 to rotate at high speed, achieving the effect of the blades 305 crushing the electrodes. Waste lithium battery electrodes are crushed and then fall below the filter frame 302, where they are ground by the grinding roller 306. This integrated crushing and grinding process improves operational efficiency. After grinding, maintenance is performed by using the electric telescopic rod 202 to raise the sealing cover 3 to a specified height. This allows for cleaning of blockages in the mesh of the filter frame 302 and cleaning of the outer wall of the grinding roller 306, reducing the risk of equipment damage. During grinding, the vibrator 204 and springs 103 on the operating frame 1 vibrate the grinding tank 2 at high speed, facilitating the crushing and grinding of the waste lithium battery electrodes and ensuring uniform grinding. This avoids uneven grinding that can occur with static grinding, effectively improving the performance and efficiency of the waste lithium battery electrode grinding equipment.
