[0002] Lithium-ion batteries, with their advantages of high energy density and long cycle life, have been widely used in electric vehicles, drones, and home energy storage. The positive and negative electrode slurries are the core components for energy storage and conversion in batteries. The slurry acts as a "carrier," uniformly distributing these active materials on the electrode surface, allowing lithium ions to be smoothly inserted into the crystal lattice of the positive electrode material during charging; during discharging, lithium ions can be extracted from the crystal lattice and migrate to the negative electrode through the electrolyte, thus realizing the battery's charging and discharging functions.

[0003] However, existing equipment is not convenient for completely adsorbing magnetic foreign objects in the slurry, and it is also not convenient for collecting the adsorbed magnetic foreign objects, which will hinder the improvement of work efficiency before testing.

[0004] Based on this, a device for enriching magnetic materials in the positive and negative electrode slurries of batteries is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0007] Preferably, the water inlet mechanism includes a water inlet hole, a water inlet pipe, and a top cover. The mixing tank is equipped with a top cover, which is connected to one end of the water inlet pipe. The top cover has a plurality of water inlet holes that are connected to the water inlet pipe.

[0008] Preferably, the support mechanism includes bearing plates, support columns, and connecting blocks.

[0010] Preferably, a plurality of electromagnetic rods are embedded in the inner wall of the mixing tank.

[0011] Preferably, the bottom wall of the mixing tank is provided with a conical wall.

[0012] The advantages of this utility model compared to the prior art are:

[0013] This invention involves loading the slurry into a mixing tank, inserting a water inlet pipe for automatic water intake, removing the water inlet pipe after completion, closing the top cover, placing the mixing tank on a support platform, securing it with a fastening strap, and tightening it.

Detailed Implementation

[0020] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0021] Reference Figures 1-5 A device for enriching magnetic materials in positive and negative electrode slurries of batteries includes a stirring tank 101, a discharge port 104 on the lower side wall of the stirring tank 101, a fixed base 106 below the stirring tank 101, a rotating platform 105 rotatably mounted on the fixed base 106, a support platform 102 on the rotating platform 105, a power contact piece 103 on the support platform 102, a groove at the bottom of the stirring tank 101 that engages with the support platform 102, a water inlet mechanism 400 mounted on the stirring tank 101, and a support mechanism 300 and a fastening mechanism 200 for stabilizing the stirring tank 101 on the rotating platform 105.

[0022] The mixing tank 101 is made of polyamide, which has good thermoplasticity, toughness, chemical resistance and durability. Its unique self-lubricating and solvent resistance prevent the slurry from sticking to the walls. The entire mixing tank 101 can hold 15kg of slurry. The support platform 102 on the rotating table 105 can be aligned with the groove at the bottom of the mixing tank 101 to fix the central axis position of the mixing tank 101. The power contact 103 automatically forms a circuit when the mixing tank 101 is placed on it, energizing the electromagnetic rod 107 and forming a magnetic field.

[0023] Reference Figures 1-5 The water inlet mechanism 400 includes a water inlet hole 401, a water inlet pipe 402, and a top cover 403. The top cover 403 is installed on the mixing tank 101. The top cover 403 is connected to one end of the water inlet pipe 402. The top cover 403 has a plurality of water inlet holes 401 connected to the water inlet pipe 402.

[0024] Automatic water intake can be achieved by inserting the water inlet pipe 402. The water will automatically spread out in an umbrella shape through the water inlet hole 401 to clean the inner wall of the mixing tank 101.

[0025] Reference Figures 1-5The support mechanism 300 includes a bearing plate 301, a support column 302 and a connecting block 303. The bearing plates 301 are symmetrically installed on the rotary table 105. The connecting block 303 is rotatably provided between the bearing plates 301. The other end of the connecting block 303 is provided with a support column 302. The fastening mechanism 200 is provided between the support columns 302.

[0026] The bearing plate 301 and the support column 302 are used to support the fastening band 203 passing through the connecting block 303 and to fasten the mixing tank 101.

[0027] Reference Figure 2 The fastening mechanism 200 includes a bolt 201, a threaded hole 202, and a fastening band 203. Both ends of the fastening band 203 pass through the support column 302 and slide in fit with it. A plurality of threaded holes 202 are provided on the side wall of the fastening band 203 at any end. Both ends of the fastening band 203 are penetrated by bolts 201 and fit with the threaded holes 202.

[0028] By adjusting the bolt 201 to a suitable width and passing it through the fastening band 203 and engaging it with the threaded hole 202, the two ends of the fastening band 203 can be used to restrain the mixing tank 101.

[0029] Reference Figures 4-5 The inner wall of the mixing tank 101 is embedded with several electromagnetic rods 107.

[0030] The mixing tank 101 is equipped with an embedded electromagnetic rod 107, and the embedded part of the electromagnetic rod 107 protrudes from the inner wall of the mixing tank 101, so that the slurry will continuously collide with it during mixing, resulting in more uniform dispersion and easier adsorption of magnetic materials.

[0031] Reference Figures 4-5 The bottom wall of the mixing tank 101 is provided with a conical wall 108.

[0032] The conical wall 108 inside the mixing tank 101 is designed to make it easier for the slurry to contact the inner wall of the mixing tank 101 when rotating, while increasing centrifugal force and increasing the impact force between the slurry and the inner wall of the mixing tank 101.

[0033] Working principle: After the slurry is loaded into the mixing tank 101, water is automatically introduced through the inlet pipe 402. After completion, the inlet pipe 402 is removed, the top cover 403 is closed, the mixing tank 101 is placed on the support platform 102, and the fastening strap 203 is tied and tightened. Then, it automatically rotates to adsorb magnetic substances. After adsorption is complete, the discharge port 104 is opened, and the inlet pipe 402 is inserted to automatically clean the tank body. All magnetic substances will be adsorbed onto the electromagnetic rod 107. Waste and wastewater after cleaning are discharged through the discharge port 104. At this time, the power is turned off, and then water is introduced again. The magnetic substances can then be discharged through the discharge port 104, thus easily collecting all magnetic foreign objects. This method can achieve complete adsorption of magnetic foreign objects in the slurry, save adsorption time, and improve adsorption efficiency. It also facilitates the desorption and separation of magnetic foreign objects from the electromagnetic rod 107, making it easy to collect magnetic foreign objects and saving pre-testing treatment time.

[0034] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
