Description

Technical Field

[0001] The utility model relates to the technical field of demagnetization devices, in particular to a demagnetization device for sodium ion battery cathode materials. Background Art

[0002] Sodium ion battery is a rechargeable battery technology similar to lithium ion battery. As one of the essential components of sodium ion battery, the cathode material is mainly used to reversibly insert and extract sodium ions during charge and discharge, and maintain a stable structure after multiple cycles.

[0003] During the production and preparation of sodium ion battery cathode materials, there are some magnetic elements in the raw materials, which will affect the battery performance. Therefore, it is necessary to remove these magnetic elements, and currently, electromagnetic demagnetizers are mostly used.

[0004] When the current electromagnetic demagnetizer demagnetizes, the cathode material needs to be first put into the electromagnetic demagnetizer from the feeding port, and these magnetic substances are adsorbed by the strong magnetic field inside the electromagnetic demagnetizer. Most electromagnetic demagnetizers have two discharge ports, one for discharging the adsorbed magnetic substances and the other for discharging the purified raw materials after removing the magnetic substances.

[0005] When the removed magnetic substances are discharged from the discharge port, due to being attracted by the strong magnetic field before, magnetization may occur inside them (or they may already have certain magnetism), and these substances will adhere to the inner wall of the discharge port. If not cleaned for a long time, the discharge port may be blocked. If cleaned frequently, the labor intensity will increase and the demagnetization efficiency will decrease. Summary of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a demagnetization device for sodium ion battery cathode materials to solve the problem that magnetic substances will adhere inside the magnetic discharge pipe of the current demagnetization body.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Please refer to Figures 1-5 , a demagnetization device for a sodium-ion battery cathode material, including a demagnetization body 1 and a magnetic drainage tube 2 installed at the bottom of the demagnetization body 1.

[0024] The demagnetization device for a sodium-ion battery cathode material in the present utility model is similar in structure to the existing demagnetization device for a sodium-ion battery cathode material, such as the special demagnetizer for battery cathode materials of the model: ZR0709LZ series. Such as Figures 1 to 5As shown in the figure, when the magnetic removal device for the positive electrode material of the sodium-ion battery in the present utility model is in use, first, the magnetic substances in the positive electrode material of the sodium-ion battery are normally processed by the magnetic removal body 1. Subsequently, the separated magnetic substances will be discharged to the outside from the magnetic discharge pipe 2. When the magnetic removal body 1 discharges the magnetic substances in the positive electrode material of the sodium-ion battery from the magnetic discharge pipe 2, at this time, the power mechanism can be started through an external PLC controller. After the power mechanism is started, it can drive the rotating assembly to rotate. After the rotating assembly rotates, it can drive the connecting plate 7, the mounting plate 8, the support assembly, and the rubber strip 10 to rotate. After the rubber strip 10 rotates, it can scrape the inner wall of the magnetic discharge pipe 2, thereby solving the problem that magnetic substances adhere to the inner wall of the magnetic discharge pipe 2 and even cause blockage.

[0025] It should be specifically noted here that:

[0026] 1. The internal principle of the above-mentioned magnetic removal body 1 and the PLC controller are prior arts, so no detailed description will be given.

[0027] 2. During the long-term use of the rubber strip 10, a certain degree of wear will occur. At this time, the mounting plate 8 can be separated from the connecting plate 7 through the limiting component, and then the mounting plate 8, the support assembly, the rubber strip 10, etc. can be cleaned and replaced.

[0028] 3. The rubber strip 10 can be made of materials that are not easily magnetized, such as silica gel and rubber.

[0029] Please mainly refer to Figures 2-4 , the power mechanism includes a support plate 4 and a motor 5. One end of the support plate 4 is fixedly connected to the outer wall of the lower end of the magnetic discharge pipe 2, and the other end of the support plate 4 is fixedly connected to the outer wall of the motor 5. The output shaft of the motor 5 penetrates the upper surface of the support plate 4 and is connected to the rotating assembly.

[0030] More specifically, when it is necessary to control the rotation of the rotating assembly, only need to turn on the motor 5 through the PLC controller. After the motor 5 is started, the output shaft can drive the rotating assembly to rotate.

[0031] Please mainly refer to Figure 4 , a rotating groove 201 is opened on the outer wall of the lower end of the magnetic discharge pipe 2, and the end of the rotating assembly away from the motor 5 is located in the rotating groove 201.

[0032] More specifically, by setting the rotating groove 201, a support can be provided for the rotating assembly to increase stability.

[0033] Please mainly refer to Figures 2-4, the rotating assembly includes a first gear 3 and a second gear 6. The first gear 3 is sleeved on the outer wall of the rotating groove 201, and the side wall of the first gear 3 is rotatably connected to the inner wall of the rotating groove 201. The bottom surface of the first gear 3 is fixedly connected to the upper end of the connecting plate 7. The upper end of the second gear 6 is fixedly connected to the output shaft of the motor 5, and the first gear 3 and the second gear 6 are meshed with each other.

[0034] More specifically, when the motor 5 is started, the output shaft can drive the second gear 6 to rotate. After the second gear 6 rotates, it can drive the first gear 3 to rotate by meshing. As the first gear 3 rotates, the connecting plate 7 can be driven to rotate.

[0035] Please mainly refer to Figure 5 , a rectangular groove 701 is formed through the lower end of the connecting plate 7, and the limiting assembly is located in the rectangular groove 701.

[0036] More specifically, by setting the rectangular groove 701, a storage and support can be provided for the limiting assembly, thereby increasing the connectivity between the connecting plate 7 and the mounting plate 8.

[0037] Please mainly refer to Figures 3-5 , the limiting assembly includes a threaded rod 11, a nut 12 and a rectangular block 14. One end of the rectangular block 14 is fixedly connected to one end of the mounting plate 8 close to the connecting plate 7, the other end of the rectangular block 14 is fixedly connected to one end of the threaded rod 11, the outer wall of the rectangular block 14 matches and is slidably connected to the inner wall of the rectangular groove 701, the other end of the threaded rod 11 penetrates through the rectangular groove 701 and the nut 12, and the outer wall of the threaded rod 11 is threadedly connected to the inner wall of the nut 12. The side wall of the nut 12 abuts against the side wall of the lower end of the connecting plate 7.

[0038] More specifically, when it is necessary to separate the connecting plate 7 and the mounting plate 8, only need to rotate the nut 12 to rotate and separate the nut 12 from the threaded rod 11, and then the threaded rod 11, the rectangular block 14, the mounting plate 8, etc. can be taken out of the rectangular groove 701 together, which is convenient and easy to operate.

[0039] It should be particularly noted here that: due to the functions of the rectangular block 14 and the rectangular groove 701, when the nut 12 squeezes the connecting plate 7 and the mounting plate 8 tightly, the mounting plate 8 itself will not rotate, so the stability of the support assembly and the rubber strip 10 can be ensured.

[0040] Please mainly refer to Figures 3-5 , the support assembly includes an L-shaped rod 9 and two anti-detachment pieces 13. One end of the L-shaped rod 9 is fixedly connected to the end of the mounting plate 8 away from the connecting plate 7. The other end of the L-shaped rod 9 penetrates through the rubber strip 10 and the two anti-detachment pieces 13, and the outer wall of the L-shaped rod 9 is fixedly connected to the inner walls of the rubber strip 10 and the two anti-detachment pieces 13.

[0041] More specifically, by providing a support component, the rubber strip 10 can be supported to prevent the rubber strip 10 made of a soft material from bending, thus affecting the scraping effect.

[0042] It should be specifically noted here that:

[0043] 1. Installing the rubber strip 10 between two anti-detachment pieces 13 can prevent the rubber strip 10 from falling off from the upper and lower ends of the L-shaped rod 9.

[0044] 2. One of the anti-detachment pieces 13 located at the upper end can be detachably connected to the L-shaped rod 9 by bolts. In this way, when the rubber strip 10 is severely worn and cannot be used anymore, the rubber strip 10 can be replaced.

[0045] 3. The L-shaped rod 9 is configured in an L shape. In this way, when the L-shaped rod 9 and the rubber strip 10 rotate to scrape magnetic substances, the scraped substances are not likely to fall off or even accumulate on the mounting plate 8.

[0046] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
