Description

Technical Field

[0001] The invention relates to the technical field of battery material processing, in particular to a ball mill for processing tubular liquid-rich power storage batteries. Background Art

[0002] At present, in the process of battery material processing, the particle size of the positive electrode material needs to be strictly controlled when grinding. The particle size of the positive electrode material has an important influence on the battery performance. Too large a particle size may lead to an increase in the internal resistance of the battery, affecting the charge and discharge performance of the battery. When processing the negative electrode material, although the particle size of the negative electrode material is not as complicated as the positive electrode material process, the negative electrode material powder also needs to have good dispersibility to ensure that it can be evenly coated on the current collector during the battery manufacturing process. The existing ball mill does not have enough uniformity in grinding the particle size of the positive electrode material, and the grinding effect is not good. It cannot meet the requirements of the positive electrode material on particle size, surface quality, etc., which will lead to low battery production efficiency and high cost.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Through the setting of conveying mechanism, matching mechanism, auxiliary mechanism, directional carrier and distribution mechanism, when the grinding roller body grinds the positive electrode material or the negative electrode material to a certain particle size by forward and reverse rotation, the grinding roller body rotates left and right to a certain extent after being pushed to the auxiliary block by the sliding shell. Since the grinding balls have three different radii, when the grinding roller body is working, the process required for the negative electrode material is relatively simple. When the negative electrode material is ground, the particle size of the negative electrode material under processing has been processed in the first step, and its particle size is smaller than that of the grinding ball. The small range of forward and reverse movement of the grinding roller body will screen it into the internal trapezoidal notch of the grinding roller body, and as the sliding shell moves toward the auxiliary block, it will fall into the circular arc and the lower notch of the grinding roller body due to the inclination angle of the grinding roller body and the rotation of the roller body. , while the larger grinding balls cannot fall into the trapezoidal notch. Most of the larger balls will be above the mixture, while most of the smaller and medium diameter grinding balls will be in the middle and lower part of the mixture. At this time, the sliding shell will no longer move due to the smaller gap in the mixture, and the output end of the cylinder will continue to drive the disc-shaped push block forward to push the larger large-diameter grinding balls to the rolling notch, and send most of the large-diameter grinding balls out along the rolling notch. Then the output end of the cylinder retracts, and the grinding roller continues to rotate forward and reverse 360 ​​degrees. The small-diameter grinding balls can penetrate into the raw materials for fine mixing, thereby improving the uniformity of grinding, making the negative electrode material particles finer, and the channels for lithium ion embedding and extraction shorter, reducing the replacement process, while improving the battery's charging and discharging performance, thereby improving work efficiency;

[0015] Through the joint operation of the distribution mechanism, the distribution mechanism screens the three different types of spheres, large, medium and small, and packs them into the distribution shell. Then, the small-diameter and some medium-diameter spheres are put into the grinding cavity according to the ratio of the positive electrode grinding material through the conveying mechanism. When the device is grinding the positive electrode material, the large-diameter grinding spheres can be delivered in time, and the small-diameter ones can be increased. The characteristics of grinding balls of different diameters are used to increase the impact frequency of the materials, flexibly control the grinding effect, and meet the different requirements of the positive electrode materials on particle size, surface quality, etc., while adjusting and optimizing the production efficiency of battery materials, reducing production costs.

[0039] Specific working principle:

[0040] The positive electrode material or the negative electrode material is put into the interior of the grinding roller body 7, and then the driving motor 82 drives the first rotating tooth 84 to work, so that the grinding roller body 7 starts to rotate. After the grinding roller body 7 rotates 360 degrees, it rotates 360 degrees in the opposite direction according to the set trajectory, so that the material and the grinding ball 9 are continuously ground inside the grinding roller body 7. Then, when the material needs to further reduce its particle radius, the first rotating tooth 84 will drive the grinding roller body 7 to perform a forward and reverse motion of 90 to 180 degrees. At this time, the cylinder 73 starts to push the disc-shaped push block 714 forward to move it close to the auxiliary mechanism 72. When the sliding shell 711 moves to a certain stroke, the gap between the ball and the material mixture will become smaller. At the same time, the material in the mixture will be below the grinding roller body 7, and the larger grinding ball 9 will be in the mixing The grinding balls 9 are pushed to the top of the material by the disc-shaped push block 714 to the rolling groove 723, and then sent out of the grinding roller body 7. The grinding balls 9 will be transported to the storage inside the load-sharing shell 111 by the second delivery rod 105 and the first delivery rod 103. When different grinding balls 9 are required to be ground in different proportions, the conveyor belt body 43 inside each required extension shell 42 is started to transport the grinding balls 9 to the inside of the grinding roller body 7 again. Then the output end of the cylinder 73 is reset and the matching mechanism 71 is pulled back. At this time, the grinding balls 9 put into the grinding roller body 7 will be mixed with the material again. The driving motor 82 drives the first rotating tooth 84 to rotate 360 ​​degrees in the forward and reverse directions of the set trajectory again for working grinding. When the grinding is completed, the material is taken out for the next battery processing.
