Description

Technical Field

[0001] This invention relates to the field of battery material processing technology, specifically to a ball mill for processing tubular flooded power batteries. Background Technology

[0002] Currently, in the battery material processing, the particle size of the positive electrode material needs to be strictly controlled during grinding, as the particle size has a significant impact on battery performance. Excessively large particles may increase the battery's internal resistance, affecting its charge and discharge performance. While the particle size processing for the negative electrode material is less complex than that for the positive electrode material, the negative electrode powder still needs to have good dispersibility to ensure uniform coating on the current collector during battery manufacturing. Existing ball mills do not provide sufficient uniformity in grinding the positive electrode material, resulting in poor grinding effects and failing to meet the requirements for particle size and surface quality, leading to low battery production efficiency and high costs. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: a ball mill for processing tubular flooded power batteries, comprising a loading base plate, two fixed carrier plates fixedly connected to the top two sides of the loading base plate, bearings fixedly connected inside the two fixed carrier plates, a conveying mechanism fixedly connected to the surface of one of the fixed carrier plates, an arc-shaped opening provided on the surface of the other fixed carrier plate aligned with the center of the bearing, and a delivery arc block inclinedly provided on the surface of the other fixed carrier plate at the notch of the arc-shaped opening, a grinding roller body provided on the inner shaft of the bearing, an directional carrier body provided on the top of the loading base plate near one of the fixed carrier plates, several grinding balls being installed inside the grinding roller body, and the grinding balls being of three diameters: large, medium, and small, and a carrier housing provided at the top of the directional carrier body, the top of the carrier housing being fixed A drive motor is connected, and a stabilizing block is fixedly connected to the output end of the drive motor. A first rotating tooth is fixedly connected to the surface of the stabilizing block, and the first rotating tooth meshes with the middle of the surface of the grinding roller. A loading mechanism that cooperates with the conveying mechanism is also provided on the top of the loading base plate away from the directional carrier. A delivery mechanism is also provided on the surface of another fixed carrier plate at the gap between the arc-shaped opening and the delivery arc block. Several sets of trapezoidal blocks are fixedly connected in a circular array at the groove gap of the inner wall of the grinding roller on one side. A matching mechanism is slidably connected on the inner wall of the grinding roller near the trapezoidal blocks. An auxiliary mechanism is provided at one end of the inside of the grinding roller. The auxiliary mechanism is close to the fixed carrier plate with the arc-shaped opening. A cylinder is fixedly connected to the inside of the grinding roller near the matching mechanism through a limiting carrier.

[0004] Furthermore, the conveying mechanism includes a C-shaped housing fixedly connected to the surface of one of the fixed carrier plates. Three extended housings are fixedly connected to the surface of the C-shaped housing and are inclined. A conveyor belt body is fixedly connected inside the C-shaped housing and the extended housings. The surface of the conveyor belt body is provided with several sets of circular slots.

[0005] Furthermore, the mating mechanism includes a sliding housing slidably connected to the inner wall of the grinding roller. The interior of the sliding housing has several sets of limiting arcs arranged in a circumferential array. A long rod is slidably connected inside the limiting arcs. A spring is fixedly connected to one end of the long rod, and a disc-shaped push block is fixedly connected to the other end of the long rod. The surface of the disc-shaped push block is fixedly connected to the output end of the cylinder. The inner ring portion of the disc-shaped push block has several sets of pushing slots arranged in a circular array. The pushing slots are conical, with a large opening on the side near the long rod.

[0006] Furthermore, the auxiliary mechanism includes an auxiliary block disposed inside the grinding roller body, the auxiliary block having a circular arc opening in the center of its surface and a rolling groove in the center of its surface.

[0007] Furthermore, the loading mechanism includes a loading housing disposed at the top of the loading base plate, the interior of the loading housing is provided with three sets of vertical plates, and the surface of the loading housing is provided with conveying pipes corresponding to the number of extended housings, the conveying pipes being inclined and communicating with the interior of the loading housing.

[0008] Furthermore, a circular slot is provided on the top of the directional carrier near the side of the carrier housing, and the arc of the circular slot is greater than the arc of the grinding roller that meshes with the first rotating tooth.

[0009] Furthermore, the side of the carrier housing closest to the grinding roller is curved, and the curvature of the curved surface is greater than the range of motion of the grinding roller.

[0010] Furthermore, the grinding roller is inclined, and the horizontal plane of the grinding roller is lower than that of the other fixed carrier plate.

[0011] Furthermore, the interior of the grinding roller body has several sets of trapezoidal slots arranged in a circular array. The grinding balls are divided into three diameters: large, medium, and small. The small-diameter grinding balls can fall into the bottom surface of the trapezoidal slots. The radius of the medium-diameter grinding balls is smaller than the large opening radius of the trapezoidal slots, and the radius of the large-diameter grinding balls is larger than the large opening radius of the trapezoidal slots.

[0012] The delivery mechanism includes a turning baffle disposed on the surface of another of the fixed carrier plates. The surface of the turning baffle is fixedly connected to a first delivery rod and a second delivery rod by a first bent rod and a second bent rod, respectively. The second delivery rod and the first delivery rod form an acute angle, and the tilt angle is the same as that of the upper part of the split-load housing.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] Through the arrangement of conveying, cooperating, auxiliary, directional carrier, and delivery mechanisms, the grinding roller grinds the positive or negative electrode material to a certain particle size by rotating it forward and backward. Then, it is pushed towards the auxiliary block by the sliding shell. The grinding roller then rotates left and right to a certain extent. Since the grinding balls have three different radii, the negative electrode material, whose processing steps are relatively simple, already has a smaller particle size than the grinding balls due to the initial processing. The small-range forward and reverse movement of the grinding roller will sieve the material into the trapezoidal groove inside the grinding roller. Furthermore, as the sliding shell moves towards the auxiliary block, the material will fall into the circular arc opening and the lower groove of the grinding roller due to the roller's tilt angle and rotation. Larger grinding balls cannot fall into the trapezoidal groove. Most of the larger balls will be above the mixture, while smaller and medium-diameter grinding balls will be in the lower middle of the mixture. At this time, the sliding shell will stop moving due to the smaller gap in the mixture, and the output end of the cylinder will continue to drive the disc pusher forward, pushing the larger diameter grinding balls to the rolling groove. Most of the large diameter grinding balls will be sent out along the rolling groove. Then the output end of the cylinder will retract, and the grinding roller will continue to rotate 360 ​​degrees in both forward and reverse directions. The small diameter grinding balls can penetrate deep into the raw material for fine mixing, thereby improving the grinding uniformity. This will make the negative electrode material particles finer and the lithium ion insertion and extraction channels shorter, reducing the replacement process and improving the battery's charging and discharging performance, thereby improving work efficiency.

[0015] Through the joint operation of the distribution mechanism, the distribution mechanism sorts three different types of spheres (large, medium, and small) into the loading shell for partial packaging. Then, the conveying mechanism feeds the small-diameter and some medium-diameter spheres into the grinding chamber according to the ratio of the positive electrode grinding material. This allows the device to promptly deliver large-diameter grinding spheres and increase the input of small-diameter spheres when grinding the positive electrode material. By utilizing the characteristics of grinding spheres of different diameters, the impact frequency of the material is increased, and the grinding effect is flexibly controlled. At the same time, it meets the different requirements of the positive electrode material for particle size, surface quality, etc., thereby reducing production costs while adjusting and optimizing the production efficiency of battery materials.

The cylinder 73 pushes the disc pusher 714 forward to move it closer to the auxiliary mechanism 72. When the sliding housing 711 is displaced to a certain stroke, the disc pusher 714 pushes the larger grinding ball 9 to the rolling groove 723 and then sends out the grinding roller body 7.

[0035] Combination Figures 2-16 The conveying mechanism 4 includes a C-shaped housing 41 fixedly connected to the surface of one of the fixed carrier plates 2. Three extended housings 42 are fixedly connected to the surface of the C-shaped housing 41 and are inclined.

The top of the directional carrier 8 is close to... A circular slot is provided on one side of the carrier housing 81. The curvature of the circular slot is greater than the curvature of the grinding roller 7 that meshes with the first rotating tooth 84. The side of the carrier housing 81 near the grinding roller 7 is curved, and the curvature of the curved surface is greater than the range of motion of the grinding roller 7. The curved surface on one side of the carrier housing 81 allows the device to operate without affecting the work of the grinding roller 7. The grinding roller 7 is inclined, and the horizontal plane of the grinding roller 7 near the other fixed carrier plate 2 is lower. The inclined setting of the grinding roller 7 allows for more efficient crushing of materials and grinding of balls inside the device. At the same time, it also facilitates the subsequent removal of the finished product after grinding.

[0037] The interior of the grinding roller 7 has several sets of trapezoidal slots arranged in a circular array. The grinding balls 9 are divided into three diameters: large, medium, and small. The small diameter grinding balls 9 can fall into the bottom surface of the trapezoidal slots.

[0039] Specific working principle:

[0040] The positive or negative electrode material is fed into the grinding roller 7. Then, the drive motor 82 drives the first rotating tooth 84 to rotate the grinding roller 7. After rotating 360 degrees, the grinding roller 7 rotates 360 degrees in the opposite direction according to a set trajectory, causing the material and grinding balls 9 to be continuously ground inside the grinding roller 7. Subsequently, when the material needs further reduction in particle size, the first rotating tooth 84 will drive the grinding roller 7 to perform a forward and reverse rotation of 90 to 180 degrees. At this time, the cylinder 73 begins to push the disc-shaped pusher 714 forward, bringing it closer to the auxiliary mechanism 72. When the sliding housing 711 has moved to a certain distance, it will reduce the gap between the mixture of balls and material. Simultaneously, the material in the mixture will be below the grinding roller 7, while the larger grinding balls 9 will be in the middle of the mixture. Above the material, the disc-shaped pusher 714 pushes the larger grinding ball 9 to the rolling groove 723, and then sends it out of the grinding roller 7. The grinding ball 9 will be transported to the storage housing 111 by the second feed rod 105 and the first feed rod 103 to grind grinding balls 9 of different radii. When different grinding ball ratios are required for grinding, the conveyor belt body 43 inside each required extension housing 42 is activated to transport the grinding ball 9 back to the grinding roller 7. Then the output end of the cylinder 73 is reset, pulling back the mating mechanism 71. At this time, the grinding ball 9 put into the grinding roller 7 will be mixed with the material again. The drive motor 82 drives the first rotating tooth 84 to rotate 360 ​​degrees in both directions on the set trajectory for grinding. After grinding is completed, the material is taken out for the next battery processing step.
