Description

Technical Field

[0001] This utility model belongs to the field of lithium battery cathode material processing technology, and particularly relates to a structure for reprocessing batch mixing of lithium battery cathode materials. Background Technology

[0002] Rework batch mixing of lithium battery cathode materials refers to the process in which, during the production of lithium battery cathode materials, some batches of products fail to meet quality standards due to various reasons. These substandard batches need to be remixed to bring them up to standard or make them usable again. During this process, the cathode materials to be reworked are placed in a container equipped with a stirring device, and mechanical stirring is used to ensure thorough and uniform mixing. Parameters such as stirring speed, time, and impeller design affect the mixing effect and need to be optimized and adjusted according to the material characteristics and batch size.

[0003] When reworking and batch mixing lithium battery cathode materials, lifting equipment is used to transport ton bags. However, during the transportation and disassembly of ton bags, metal foreign objects are easily mixed in, and the materials are easily contaminated, affecting the quality control of finished products. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a rework batch mixing structure for lithium battery cathode materials, which more precisely solves the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a structure for rework batch mixing of lithium battery cathode materials, including a mounting frame, on which a small material hopper is mounted. The mounting frame is provided with a circular through groove aligned with the opening of the small material hopper. An mounting component is provided on the upper surface of the mounting frame, and a ton bag placement base is placed on the mounting component. The ton bag placement base is connected to the small material hopper, and a ton bag opening is provided on one side of the ton bag placement base.

[0007] Preferably, the mounting frame includes a base plate, a support rod is fixedly connected to the upper surface of the base plate, a horizontal plate is fixedly connected to the upper end of the support rod, the horizontal plate is fixedly connected to the small hopper, a circular through groove is located on the horizontal plate, and four fixable pulleys are installed on the lower surface of the base plate.

[0008] Preferably, the lower end of the small hopper is connected to a material discharge pipe.

[0009] Preferably, a pneumatic vibrator is installed between the small hopper and the material discharge pipe.

[0010] Preferably, the mounting assembly includes four guide posts, which are fixedly connected to the horizontal plate. Four mounting tubes are fixedly connected to the side of the ton bag placement base. The mounting tubes cooperate with the guide posts. The lower inner side of the mounting tube is provided with a tapered surface. A rubber plug is installed at the upper position of the guide post.

[0011] Preferably, the sides of the ton bag placement base are fixedly connected to threaded posts on both sides of the ton bag opening, a baffle is provided inside the ton bag opening, and fixed plates are fixedly connected to both sides of the baffle. The fixed plates are provided with through holes that cooperate with the threaded posts, and nuts are provided on the threaded posts.

[0012] The rework batch mixing structure for lithium battery cathode materials proposed in this utility model can bring the following beneficial effects:

[0013] 1. By setting the opening of the ton bag, the ton bag is placed in the ton bag placement base. At this time, the opening of the ton bag is opened, the bottom of the ton bag is opened, and an opening is made at the bottom of the aluminum foil bag through the opening of the ton bag using a ceramic knife. Then the opening of the ton bag is closed to prevent dust and foreign objects from entering. The whole process reduces the introduction of metal foreign objects, improves the quality of finished products, is easy to operate, saves manpower and working time, and improves production efficiency.

[0014] 2. By setting the installation components, after the four guide posts are aligned and inserted into the installation tube, the ton bag placement base is aligned with the small hopper. As the ton bag placement base descends, the lower end of the ton bag placement base contacts the upper end of the hopper. At this time, rubber plugs are installed on the upper end of the guide posts to make the connection between the ton bag placement base and the small hopper tighter. By setting the four guide posts and installation tube, the ton bag placement base is supported, making it more stable and preventing the ton bag placement base from being crushed after the ton bag enters it.
