Description

Technical Field

[0001] The utility model relates to the technical field of lithium ion battery positive electrode material processing, in particular to a filtering and screening device for lithium ion battery positive electrode material processing. Background Art

[0002] Lithium-ion battery is a secondary battery that mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. When charging, Li+ is deintercalated from the positive electrode and embedded into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true when discharging. When filtering and screening the existing filtering and screening devices for processing positive electrode materials of lithium-ion batteries, the positive electrode materials of lithium-ion batteries cannot be filtered and screened multiple times, which affects the screening quality of the positive electrode materials, and it is inconvenient to remove the positive electrode materials after screening, which affects the efficiency of filtering and screening the positive electrode materials.

[0003] In the prior art, a Chinese patent document with publication number CN217474058U is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a filtering and screening device for processing positive electrode materials of lithium-ion batteries, comprising a screening tank, a first mounting frame, a second mounting frame, a third mounting frame, a flow pipe, a first discharge box and a second discharge box are fixedly connected to the side of the screening tank, a telescopic mechanism is fixedly installed on the first mounting frame, a first rotating mechanism is fixedly installed on the second mounting frame, a first baffle plate is slidably connected in the first discharge box, a second baffle plate is slidably connected in the second discharge box, and a leak plate and a drawer are slidably connected in the screening tank.

[0004] In order to solve the problem that the filtering and screening device cannot filter and screen multiple times, affecting the screening quality, and is inconvenient to take out and affecting the efficiency, the existing technology adopts a method of setting a screening plate and a leakage plate for two filtrations, and setting two sets of material baffle plates and drawers for classified collection. However, the filter plate is fixed, and the material is easily damaged by collision when it falls, and the motor will have too high temperature when working for a long time, which leads to poor buffering effect of the filter plate and low efficiency of the motor working at high temperature. Utility Model Content

[0005] The utility model aims to provide a filtering and screening device for processing positive electrode materials of lithium ion batteries, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

By classifying the discharge valves, materials of different sizes filtered out can be taken out, which is convenient for screening and collection.

[0013] A further improvement of the technical solution of the utility model is that the stirring device includes a servo motor fixedly mounted on the surface of one side of the processing box body close to the servo electric cylinder, a rotating rod is fixedly mounted on the output end of the servo motor, and a stirring rod is fixedly mounted on the surface of the rotating rod. The material is stirred by rotating the stirring rod, so that the powdered material can be filtered into the drawer through the filter plate to achieve separation.

[0014] A further improvement of the technical solution of the utility model lies in that: the heat dissipation box includes a heat dissipation box body fixedly mounted on the surface of one side of the processing box body, the surface of the heat dissipation box body is provided with a mounting groove, and a heat dissipation fan is fixedly mounted on the surface of the mounting groove. By setting up the heat dissipation box, the servo electric cylinder and the servo motor are arranged in the same space, which is convenient for using the heat dissipation fan for ventilation and heat dissipation, thereby preventing the two sets of motors from being used for a long time, resulting in reduced work efficiency and safety problems.

[0015] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0016] The utility model provides a filtering and screening device for processing positive electrode materials of lithium ion batteries. By arranging a baffle, it can prevent the materials from falling from the inner gap during screening, resulting in inaccurate screening. It can also prevent the stirrer from being unable to stir the materials at the edge, resulting in material accumulation and difficulty in taking out.

[0017] The utility model provides a filtering and screening device for processing positive electrode materials of lithium ion batteries. By arranging a spring rod at the bottom of the filter plate, the filter plate can have a certain buffering effect, which effectively prevents the positive and negative electrode materials from contacting and colliding with the filter plate when they fall after screening, causing damage and affecting the quality.

[0018] The utility model provides a filtering and screening device for processing lithium-ion battery positive electrode materials. By arranging a heat dissipation box, a servo electric cylinder and a servo motor are arranged in the same space, which is convenient for using a heat dissipation fan for ventilation and heat dissipation, thereby preventing the two sets of motors from being used for a long time, resulting in reduced work efficiency and safety problems.
