Description

Technical Field

[0001] This utility model relates to the field of material performance testing technology, specifically to a magnetic material cleaning device. Background Technology

[0002] The detection of magnetic foreign matter content in the positive electrode material, its precursor, and lithium salt used in battery manufacturing is one of the important criteria for determining whether nickel-cobalt-manganese ternary materials can be used to manufacture high-performance batteries.

[0003] Currently, the testing process for this project includes several steps. First, the magnetic sample is enriched in a 500mL beaker and allowed to stand for 3-5 minutes before magnetic adsorption begins. A 6000GS magnetic block is placed firmly against the bottom of the beaker, and the sample is rotated three times clockwise and three times counterclockwise, constituting one round of adsorption. Three rounds of adsorption are performed, with each round lasting at least 3 seconds. The magnetic block is then placed in the center of the bottom of the beaker, and the beaker is slowly tilted to drain the water. The beaker is then rinsed with primary water until the solution is clear. During the rinsing process, the magnetic block must not leave the bottom of the beaker, and the adsorption area where the magnetic block is located should not be directly rinsed. After rinsing, 15ml (1+1) of hydrochloric acid is added to the beaker, and the mixture is sonicated for 2 minutes. The 6000GS magnetic block is again placed firmly against the bottom of the beaker, and the beaker is rinsed three times with primary water using the same method as the previous step until no visible material remains in the beaker.

[0054] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below: The tilting frame 200 is rotatably connected to the base 100. The beaker 130 is held in the clamping gap by the clamping member 310 and is connected to the tilting frame 200 together with the clamping member 310. The magnetic stirrer 320 and the ultrasonic transducer 330 are both connected to the tilting frame 200 and abut against the bottom of the beaker 130 respectively, for cleaning and separating the magnetic materials in the beaker 130. Under the drive of the drive component 400, the tilting frame 200 can rotate the beaker 130 at a preset angle to pour out the solution in the beaker 130. Compared to existing technologies, by setting up a clamping component 310 to clamp and fix the beaker 130 so that it can be detachably connected to the tilting frame 200, the magnetic material washed out in the beaker 130 is separated by the magnetic stirrer 320 and the ultrasonic transducer 330, and then the driving component 400 drives the tilting frame 200 and the beaker 130 to rotate relative to the base 100 at a preset angle, which can realize the pouring of the solution in the beaker 130. Under the action of the magnetic stirrer 320, the magnetic material is retained in the beaker 130, realizing the automation of the magnetic material cleaning process and reducing the operational errors caused by manual operation.

[0055] In the specific working process of this utility model, the user first uses a magnetic stirrer and an ultrasonic converter to separate the magnetic material. The magnetic stirrer 320 has a replaceable magnetic block that can move clockwise and counterclockwise along a specific trajectory, causing the magnetic material to be attracted to the bottom of the beaker 130. Then, driven by the stepper motor 410, the tilting frame 200 rotates at a preset angle relative to the column 110 on the base 100. At this time, the beaker 130 tilts relative to the base 100, causing the liquid inside the beaker 130 to... The contents are poured out, and after the pouring is complete, the beaker 130 and the tilting frame 200 rotate and return to their original positions. Some fine particles adhere to the wall of the beaker 130. The nozzle 810 sprays water onto the inner wall of the beaker 130, and the magnetic material in the beaker 130 is cleaned a second time under the combined action of the magnetic stirrer and the ultrasonic converter. Finally, the stepper motor 410 drives the tilting frame 200 to rotate again relative to the column 110 on the base 100 at a preset angle, pouring out the material in the beaker 130 until the magnetic material is completely separated from the liquid.

[0056] Furthermore, all steps in the entire process are completed automatically by the equipment, which not only reduces manual operation, but also reduces operational errors caused by manual operation, minimizing the impact on test results and ensuring high test accuracy.

[0057] This application, through the above structure, can solve the technical problem in the prior art where the detection of magnetic foreign matter content in magnetic materials mainly relies on manual operation, which is prone to operational errors and thus affects the test results.
