Description

Technical Field

[0001] This utility model relates to the technical field of magnetic particle separation, and in particular to a device for separating different magnetic particles. Background Technology

[0002] Lithium-ion batteries are widely used in electric vehicles, residential energy storage, and industrial and commercial energy storage due to their advantages such as high energy density, long cycle life, and environmental friendliness.

[0003] With technological advancements, researchers have discovered that lithium-ion batteries contain numerous magnetic particles, which can negatively impact the cell's voltage drop, cycle life, and other performance characteristics. Therefore, the monitoring and control of magnetic metal particles is crucial. Traditional methods for collecting magnetic metal particles involve using a 5000-10000 Gs magnetic rod to magnetically adsorb the sample, then rinsing the adsorbed particles onto the rod with deionized water into a beaker for collection. This process is repeated 2-3 times.

[0004] Traditional methods for collecting magnetic metal particles rely on manual operation, which is not only inefficient and inaccurate, but also unable to distinguish magnetic particles with different magnetic properties. Utility Model Content

[0005] The purpose of this invention is to provide a device for separating different magnetic particles, thereby alleviating the technical problems of traditional magnetic metal particle collection methods that rely on manual operation, which are not only inefficient and inaccurate, but also unable to distinguish magnetic particles with different magnetic properties.

[0006] This utility model provides a device for separating different magnetic particles, including a device body, a separation chamber provided inside the device body, a separation plate provided inside the separation chamber, one end of the separation plate being connected to the inner wall of the upper end of the device body, and the other end being connected to the inner wall of the lower end of the device body.

[0007] The separating plate divides the separation chamber into an upper separation chamber and a lower separation chamber; an upper feed port is provided at the upper end of the main body of the device, and a lower discharge port is provided at the lower end of the main body of the device, and both the upper feed port and the lower discharge port are connected to the upper separation chamber.

[0018] The device for separating different magnetic particles provided by this utility model has multiple electromagnetic rods on its main body. The electromagnetic rods have different magnetic forces.

[0027] Example

[0028] Reference Figure 1 This utility model provides a device for separating different magnetic particles, including a device body 100, a separation chamber is provided inside the device body 100, a separation plate 400 is provided inside the separation chamber, one end of the separation plate 400 is connected to the inner wall of the upper end of the device body 100, and the other end is connected to the inner wall of the lower end of the device body 100.

[0029] The separation plate 400 divides the separation chamber into an upper separation chamber 200 and a lower separation chamber 300; an upper feed port 500 is provided at the upper end of the device body 100, and a lower discharge port 700 is provided at the lower end of the device body 100, and both the upper feed port 500 and the lower discharge port 700 are connected to the upper separation chamber 200.

[0030] A plurality of electromagnetic rods 110 are provided in the lower separation chamber 300, and the plurality of electromagnetic rods 110 are arranged sequentially at intervals along the separation plate 400.

[0031] In some embodiments, multiple electromagnetic rods 110 are arranged sequentially. Magnetic particles with different magnetic properties enter from the upper feed port 500 and flow onto the separation plate 400. The magnetic particles with different magnetic properties flow along the separation plate 400. Since the electromagnetic rods 110 have different magnetic permeabilities, the magnetic force exerted by the electromagnetic rods 110 on the magnetic particles is also different. Magnetic particles with different magnetic properties can be magnetically attracted onto the separation plate 400. This achieves the separation of different magnetic particles. When collecting magnetic particles, the electromagnetic rods 110 are de-energized, and the electromagnetic rods 110 lose their magnetic force. The magnetic particles attracted by the electromagnetic rods 110 can then move downwards along the separation plate 400.

[0032] When collecting magnetic particles, the electromagnetic rod 110 is de-energized sequentially from bottom to top, and water is poured in from the upper feed port 500. The water flow washes down the magnetic particles that have lost their magnetic attraction and discharges them from the lower discharge port 700, thus completing the collection of one type of magnetic particle. By repeating the above operation, multiple magnetic particles with different magnetic properties can be collected separately.

[0033] In an optional embodiment, the main body 100 of the device is provided with a plurality of controllers 120, each of the controllers 120 being connected to one of the electromagnetic rods 110.

[0034] In an optional embodiment, the separation plate 400 is made of plastic or glass.

[0035] In some embodiments, the device body 100 is provided with a plurality of controllers 120, and each electromagnetic rod 110 corresponds to a controller 120; generally, five controllers 120 are provided on the device body 100, with the first controller 120 controlling one electromagnetic rod 110; the plurality of magnetic particles are strongly magnetic Fe, Co, Zn, Ni and weakly magnetic Fe3P. The separation plate 400 is generally made of glass, and the separation plate 400 cannot be magnetized when the electromagnetic rod 110 is turned on.

[0036] In an optional embodiment, the upper feed inlet 500 is provided with a feed funnel 600.

[0037] In an optional embodiment, the lower discharge port 700 is provided with a lower discharge pipe 800.

[0038] In an optional embodiment, the lower separation cavity 300 is provided with a plurality of assembly slots 900, and each of the assembly slots 900 is equipped with an electromagnetic rod 110.

[0039] In an optional embodiment, the separation plate 400 is provided with a plurality of magnetic plates, and each assembly slot 900 is provided with one magnetic plate.

[0040] In an optional embodiment, a plurality of collecting devices are also included, with one collecting device corresponding to each of the electromagnetic rods 110.

[0041] In an optional embodiment, the permeability of the plurality of electromagnetic rods 110 increases sequentially from high to low.

[0042] In some embodiments, a feed funnel 600 is provided at the upper feed inlet 500 to facilitate the pouring of magnetic particles into the upper feed inlet 500; and a lower discharge pipe 800 is provided at the lower discharge inlet 700 to facilitate the collection of magnetic particles discharged from the lower discharge outlet 700.

[0043] Multiple assembly slots 900 are provided in the lower separation chamber 300, and each assembly slot 900 is provided with an electromagnetic rod 110.

[0044] To separate magnetic particles with different magnetic properties, the strength of multiple electromagnetic rods 110 increases sequentially from high to low. As the magnetic particles move along the separation path, the stronger magnetic particles are magnetically attracted to the separation plate 400 by the magnetic force generated by the first electromagnetic rod 110. The magnetic particles are magnetically attracted by the magnetic forces generated by different electromagnetic rods 110 in order of magnetic strength. The weakest magnetic particle is magnetically attracted by the electromagnetic rod 110 at the lowest point, which generates the strongest magnetic force. This achieves the separation of magnetic particles with different magnetic properties.

[0045] In order to enable the electromagnetic rod 110 to better attract magnetic particles, a magnetic guide plate is provided on the separation plate 400. The magnetic guide plate is made of metal and can be magnetized, so that the magnetic particles are more easily attracted when they come into contact with the magnetic guide plate.

[0046] When it is necessary to collect and separate different magnetic particles, each magnetic particle corresponds to a collection device; the collection device can be a beaker; the discharge pipe 800 is placed in the collection device, and then the controller 120 causes the bottom electromagnetic rod 110 to lose its magnetism; deionized water is poured in from the feed funnel 600, the deionized water washes the magnetic particles attracted by the bottom electromagnetic rod 110, and causes the magnetic particles to enter the collection device, thus completing the collection of one type of magnetic particle.

[0047] Repeat the above operation, turning off the electromagnetic rod 110 from bottom to top in sequence, and collecting the magnetic particles attracted by the corresponding electromagnetic rod 110 in sequence, thus realizing the collection of different magnetic particles.

[0048] The device body 100 of the apparatus for separating different magnetic particles provided by this utility model is equipped with multiple electromagnetic rods 110. The multiple electromagnetic rods 110 have different magnetic forces. When the magnetic particles flow along the separation plate 400, each electromagnetic rod 110 attracts a type of magnetic particle according to the different magnetic strengths of the magnetic particles, thereby separating multiple different magnetic particles. Then, the electromagnetic rods 110 are closed sequentially from bottom to top, so that the same magnetic particles are discharged sequentially from the lower discharge port 700, improving the separation efficiency of magnetic particles and enabling the separation of magnetic particles with different magnetic properties.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
