During the battery production process, magnetic substances can be introduced into the slurry due to equipment wear, improper human operation, or unsuitable storage environment. Therefore, how to efficiently remove magnetic substances from the slurry has become an urgent problem to be solved. Utility Model Content

[0003] In view of the above problems, this application provides a demagnetizing device and battery production equipment, which helps to improve demagnetizing efficiency.

[0005] In some embodiments of the first aspect, the slurry can be demagnetized by entering a demagnetizing tank connected to it through a feed channel. The demagnetized slurry can be discharged through a discharge channel. By setting multiple demagnetizing mechanisms, and having a first valve in one part of the multiple feed channels alternately open and close with a first valve in another part of the feed channels, multiple demagnetizing mechanisms can work independently. While one part of the demagnetizing mechanism is used to demagnetize the slurry, another part of the demagnetizing mechanism can be used for cleaning.

[0013] In the above technical solution, the slurry can flow between the demagnetizing tank and the buffer tank to achieve repeated demagnetization, which can greatly remove magnetic substances from the slurry and improve the quality of the slurry.

[0014] In some embodiments, the buffer mechanism further includes a first pump body and a second pump body, the first pump body being disposed in the circulation inlet pipe and configured to provide power for the slurry to enter the buffer chamber, and the second pump body being disposed in the circulation outlet pipe and configured to provide power for the slurry to exit the buffer chamber; and / or, the valve control further includes a sixth valve connected to the main inlet pipe. This configuration improves the reliability of the demagnetizing device.

[0015] In some embodiments, there are two demagnetizing mechanisms, two feeding channels, two discharging channels, and two first valves, wherein the two first valves are opened and closed alternately.

[0016] The above-mentioned design helps to reduce the volume occupied by the demagnetizing device and also helps to reduce costs.

[0017] In some embodiments, the demagnetizing mechanism further includes a drive assembly, the demagnetizing can includes a can body and a cover, the can body has a demagnetizing cavity, the cover fits onto the can body along the height direction of the demagnetizing can and has a through hole communicating with the demagnetizing cavity, the drive assembly is connected to the adsorption member and configured to drive the adsorption member to move along the height direction to extend or extend into the demagnetizing cavity through the through hole.

[0018] In the above technical solution, when the adsorption component extends into the demagnetization cavity, it can adsorb magnetic substances in the slurry. When the adsorption component extends out of the demagnetization cavity, it can be maintained.

[0019] In some embodiments, the drive assembly includes a drive member and a protective cover. The protective cover has a protective cavity and is connected to one side of the demagnetizing tank along the height direction. The drive member is connected to the side of the protective cover opposite to the demagnetizing tank along the height direction. The drive member is telescopic to drive the adsorption member to move along the height direction between the demagnetizing cavity and the protective cavity.

[0020] In the above technical solution, the protective cover can protect the adsorption component extending out of the demagnetizing cavity to prevent external impurity particles from sticking to the adsorption component, thereby preventing contamination of the slurry.

[0021] In some embodiments, the demagnetizing mechanism further includes a guide sleeve having a through hole in the height direction. The guide sleeve is connected to the cover, and a portion of the guide sleeve extends into the demagnetizing cavity through the through hole. The adsorption element extends into or out of the demagnetizing cavity through the through hole.

[0022] In the above technical solution, the guide sleeve can provide positioning and guidance for the adsorption component.

[0023] In some embodiments, the guide sleeve includes a sleeve body and a protrusion. The sleeve body extends into the demagnetizing cavity through a through hole and has a sleeve hole. The protrusion is connected to the side of the sleeve body facing away from the demagnetizing cavity along the height direction and protrudes from the sleeve body facing away from the sleeve hole along the circumferential direction of the sleeve hole.

[0025] In the above technical solution, when the adsorption component extends from the demagnetization chamber, the scraper will come into contact with the adsorption component to scrape off the magnetic material adsorbed around it, so as to facilitate subsequent cleaning.

[0026] In some embodiments, the demagnetizing mechanism further includes a cleaning component connected to the demagnetizing tank. In the cleaning state, the cleaning component is configured to introduce a cleaning medium for cleaning magnetic materials into the demagnetizing cavity.

[0027] In the above technical solution, the use of cleaning components can wash away the magnetic material scraped off by the scraper, thereby reducing labor costs.

[0028] In some embodiments, there are multiple cleaning components, which are distributed circumferentially around the demagnetizing tank.

[0030] In some embodiments, the adsorption assembly further includes an adapter connected to the side of the adsorption assembly facing the tank along the height direction, wherein the magnetic attraction capacity of the adsorption assembly is greater than that of the adapter; in the adsorption state, the scraper abuts against the adsorption assembly, and in the cleaning state, the scraper abuts against the adapter.

[0031] In the above technical solution, when the adsorption component extends from the demagnetization chamber, the scraper will gather the magnetic material on the adsorption component to the adapter, which helps to ensure the effectiveness of the magnetic material falling off the adapter during the cleaning process.

[0032] In some embodiments, during the cleaning state, a portion of the adapter is located in the sleeve hole, and another portion is located in the demagnetizing cavity. This arrangement ensures that no magnetic material remains inside the sleeve hole, preventing magnetic residue.

[0033] In some embodiments, the demagnetizing mechanism further includes a guide member, and the sleeve body also has a second groove communicating with the sleeve hole. The second groove is disposed on the side of the first groove facing away from the demagnetizing cavity along the height direction. The second groove is provided with a guide member, and the guide member protrudes from the sleeve body toward the sleeve hole and abuts against the adsorption assembly. There are multiple second grooves, and the multiple second grooves are distributed at intervals along the height direction.

[0034] In the above technical solution, the guide can further guide the movement of the adsorption component and prevent friction between the adsorption component and the guide sleeve.

[0035] In some embodiments, the demagnetizing mechanism further includes a first sealing ring disposed between the protrusion and the cover; and / or, the demagnetizing mechanism further includes a second sealing ring, and the sleeve body further has a third groove communicating with the sleeve hole, the third groove being provided with the second sealing ring, the third groove being disposed on the side of the first groove facing away from the demagnetizing cavity along the height direction, and the second sealing ring protruding from the sleeve body toward the sleeve hole and abutting against the adsorption assembly.

[0065] In this application, "multiple" means two or more (including two).

[0066] The quality of the slurry is a crucial factor affecting battery performance, and the purity of the slurry is one of the important indicators for measuring its quality. During the battery production process, magnetic substances can be introduced into the slurry due to equipment wear, improper human operation, or unsuitable storage environment. Therefore, how to efficiently remove magnetic substances from the slurry has become an urgent problem to be solved.

[0067] To address the aforementioned technical issues, this application provides a demagnetizing device, which includes a demagnetizing mechanism, a connecting pipe assembly, and a valve control. By configuring multiple demagnetizing mechanisms that can operate independently, while some demagnetizing mechanisms are used to demagnetize the slurry, others can be used for cleaning. This eliminates the need for the demagnetizing device to be shut down for cleaning the adsorption components, enabling continuous demagnetization and improving demagnetizing efficiency.

[0068] The demagnetizing device provided in this application embodiment can be provided separately or used as a component in battery production equipment, etc.

[0069] Please refer to the following: Figures 1 to 7 According to an embodiment of this application, a demagnetizing device is provided, including multiple demagnetizing mechanisms 1, connecting pipe assemblies, and valve control components. Each demagnetizing mechanism 1 includes a demagnetizing tank 11 and an adsorption assembly 12. The demagnetizing tank 11 has a demagnetizing cavity 101 and an inlet and an outlet respectively connected to the demagnetizing cavity 101. The adsorption assembly 12 includes an adsorption element 121, which is configured to adsorb magnetic substances in the slurry within the demagnetizing cavity 101. The connecting pipe assemblies have multiple inlet channels 201 and multiple outlet channels 202. The inlet channels 201 are connected to the inlet inlet one by one, and the outlet channels 202 are connected to the outlet inlet inlet one by one. The valve control components include multiple first valves 31. Each inlet channel 201 is provided with a first valve 31, which is configured to control the opening and closing of the inlet channel 201. Among the multiple inlet channels 201, the first valves 31 provided in some inlet channels 201 are opened and closed alternately with the first valves 31 provided in other inlet channels 201.

[0070] It should be noted that a demagnetizing device refers to a device that can demagnetize battery slurry to remove magnetic substances from the slurry.

[0071] The demagnetizing cavity 101 is used to contain the slurry. The demagnetizing cavity 101 can also be used to contain the adsorption element 121, so that the adsorption element 121 can be located in the demagnetizing cavity 101 to adsorb the magnetic substances in the slurry.

[0072] The adsorption member 121 refers to a component capable of adsorbing magnetic materials in a slurry. The adsorption member 121 may extend along the height direction X. The adsorption member 121 can adsorb magnetic materials in the slurry, so that the magnetic materials adhere to the adsorption member 121. The adsorption member 121 may be, but is not limited to, a magnetic rod or a magnetizable metal structure.

[0073] The connecting pipe assembly refers to the component capable of conveying slurry. The slurry can enter the demagnetizing chamber 101 through the feed channel 201 and the feed port, and the slurry in the demagnetizing chamber 101 can be discharged through the discharge channel 202 and the discharge port. Each feed channel 201 is equipped with a first valve 31, which is used to control the opening and closing of the feed channel 201.

[0074] "The first valve 31 provided in a portion of the multiple feed channels 201 is opened and closed alternately with the first valve 31 provided in another portion of the feed channels 201" means that when the first valve 31 provided in a portion of the feed channels 201 is open, the demagnetizing mechanism 1 connected to this portion can be used to demagnetize the slurry. At the same time, the first valve 31 provided in another portion of the feed channels 201 is closed, and the demagnetizing mechanism 1 connected to this portion can be used for cleaning, maintenance and other operations. By controlling the opening and closing of the first valve 31 provided in different feed channels 201, each demagnetizing mechanism 1 can work independently.

[0075] The demagnetizing devices in related technologies require regular cleaning and maintenance to remove the magnetic impurities they adsorb. During the cleaning process, the device needs to be shut down, which interrupts the demagnetizing process and affects the continuity and efficiency of demagnetization.

[0076] In contrast, the embodiments of this application differ from those of the previous one. In the embodiments of this application, multiple demagnetizing mechanisms 1 can work independently, that is, there is no communication between multiple demagnetizing tanks 11. This allows one part of the demagnetizing mechanism 1 to be used to demagnetize the slurry while another part of the demagnetizing mechanism 1 can be cleaned. This eliminates the need for the demagnetizing device to stop for cleaning the adsorption component 12, enabling continuous demagnetization and improving demagnetization efficiency.

[0077] In some embodiments, two demagnetizing mechanisms 1 are provided, and correspondingly, two feeding channels 201, two discharging channels 202, and two first valves 31 are provided. When one of the first valves 31 is open, the slurry can enter the demagnetizing tank 11 connected to it through one of the feeding channels 201 for demagnetization. The demagnetized slurry can be discharged through the discharging channel 202 connected to it. At the same time, the other first valve 31 is closed, so that the other demagnetizing mechanism 1 can be cleaned or maintained. When the adsorption element 121 used for demagnetization needs to be cleaned, the opening and closing states of the two first valves 31 are switched, so that the demagnetizing device can continuously demagnetize.

[0078] In some embodiments, the demagnetizing mechanism 1 may be configured as three or more, and correspondingly, the feed channel 201, the discharge channel 202, and the first valve 31 may be configured as three or more.

[0079] Optionally, the adsorption assembly 12 may include a plurality of adsorption elements 121 spaced apart, which is beneficial to improving the adsorption efficiency of the adsorption elements 121 in adsorbing magnetic materials, thereby improving the demagnetization efficiency of the demagnetizing device.

[0080] Optionally, the adsorption element 121 may be configured as a cylindrical, conical, or cubic shape, etc.

[0081] Optionally, the connecting pipe assembly may be made of, but is not limited to, plastic, rubber, ceramic, glass, or aluminum alloy.

[0082] In some alternative embodiments, the demagnetizing device further includes a controller electrically connected to a plurality of first valves 31 of the valve control, the controller being configured to control the opening and closing of the first valves 31 respectively.

[0083] The controller can open and close the first valve 31, which helps to improve the reliability of the demagnetizing device.

[0084] Optionally, the controller can be a programmable logic controller (PLC) to achieve automatic opening and closing of the valve control. Specifically, the controller can achieve automatic opening and closing of the first valve 31, that is, when one of the first valves 31 is closed, another first valve 31 is opened to meet the continuous demagnetization of the demagnetizing device.

[0085] like Figures 1 to 3 As shown, in some optional embodiments, the connecting pipe assembly includes a main inlet pipe 21 and a plurality of sub-inlet pipes 22, which are respectively connected to the main inlet pipe 21. Each sub-inlet pipe 22 has a feed channel 201 and is connected to a first valve 31.

[0086] The slurry can enter through the main inlet pipe 21 and be distributed to one of the feed ports through the sub-inlet pipe 22 to enter the demagnetizing tank 11.

[0087] By setting it up in the above way, the layout of the connecting pipe group can be simplified, so as to reduce the space occupied by the connecting pipe group, thereby reducing the space occupied by the demagnetizing device and also helping to reduce costs.

[0088] For example, such as Figure 2 and Figure 3 As shown, the demagnetizing device is equipped with two demagnetizing mechanisms 1, and two sub-inlet pipes 22 and two first valves 31. During the demagnetizing process, the two first valves 31 are opened and closed alternately so that the demagnetizing device always has one demagnetizing mechanism 1 for demagnetizing, while the other demagnetizing mechanism 1 can be used for cleaning or maintenance.

[0089] It should be noted that in the embodiments of this application, "alternating opening and closing" means that the two first valves 31 are not opened at the same time or not closed at the same time, and when one of the first valves 31 is open, the other first valve 31 is closed.

[0090] Optionally, the first valve 31 can be a pneumatic ball valve, or the first valve 31 can also be, but is not limited to, a pneumatic butterfly valve, a pneumatic gate valve, a pneumatic stop valve, and an electric valve.

[0091] like Figures 1 to 3 As shown, in some optional embodiments, the connecting pipe assembly further includes a main outlet pipe 23 and multiple sub-outlet pipes 24, each of which is connected to the main outlet pipe 23 and has a discharge channel 202. The valve control also includes a second valve 32, and each discharge channel 202 is provided with a second valve 32. The second valve 32 is configured to control the opening and closing of the discharge channel 202, and the sub-outlet pipes 24 are connected to the second valve 32.

[0092] The slurry in the demagnetizing tank 11 can be discharged from the outlet to the sub-outlet pipe 24 and then discharged from the main outlet pipe 23. This arrangement simplifies the layout of the connecting pipe assembly, reducing its space requirements and consequently the space occupied by the demagnetizing device, thus lowering costs.

[0093] For example, such as Figure 2 and Figure 3 As shown, the demagnetizing device is equipped with two demagnetizing mechanisms 1, and two sub-outlet pipes 24 and two second valves 32. During the demagnetizing process, the two second valves 32 are opened and closed alternately so that the demagnetizing device always has one demagnetizing mechanism 1 for demagnetizing, while the other demagnetizing mechanism 1 can be used for cleaning or maintenance.

[0094] Optionally, the second valve 32 can be a pneumatic ball valve, or the second valve 32 can also be, but is not limited to, a pneumatic butterfly valve, a pneumatic gate valve, a pneumatic stop valve, and an electric valve.

[0095] Optionally, the controller is electrically connected to a plurality of second valves 32 of the valve control, and the controller is configured to control the opening and closing of the second valves 32 respectively.

[0096] Please see Figures 2 to 5 In some embodiments, the demagnetizing device further includes a buffer mechanism 4, which includes a buffer tank 41. The buffer tank 41 has a buffer cavity and a buffer inlet and a buffer outlet respectively connected to the buffer cavity. The connecting pipe assembly also includes a circulation inlet pipe 25 and a circulation outlet pipe 26. The circulation inlet pipe 25 is connected to the main outlet pipe 23 and the buffer inlet, and the circulation outlet pipe 26 is connected to the main inlet pipe 21 and the buffer outlet. The valve control also includes a third valve 33, a fourth valve 34, and a fifth valve 35. The third valve 33 is connected to the main outlet pipe 23, the fourth valve 34 is connected to the circulation inlet pipe 25, and the fifth valve 35 is connected to the circulation outlet pipe 26.

[0097] When a single demagnetization cannot meet the requirements, cyclic demagnetization can be achieved through the buffer mechanism 4 until the slurry after demagnetization meets the requirements. The specific implementation process is as follows: after the slurry enters the demagnetization tank 11 of any one of the demagnetization mechanisms 1 for demagnetization, the demagnetized slurry enters the buffer tank 41 through the circulation inlet pipe 25. When the slurry in the buffer tank 41 reaches the preset liquid level, the slurry in the buffer tank 41 enters the demagnetization tank 11 of any other demagnetization mechanism 1 through the circulation storage tank for continued demagnetization. The demagnetized slurry continues to flow back to the buffer tank 41, and this cycle is repeated until the magnetic material content in the slurry in the buffer tank 41 is reduced to the standard. At this time, the fourth valve 34 is closed and the third valve 33 is opened to discharge the slurry.

[0098] If the adsorption element 121 of a certain demagnetizing mechanism 1 needs to be cleaned during the above process, the path is changed so that the slurry in the buffer tank 41 enters the demagnetizing tank 11 of another demagnetizing mechanism 1 through the circulation outlet pipe 26 for demagnetization.

[0099] In the above technical solution, the slurry can flow between the demagnetizing tank 11 and the buffer tank 41 to achieve repeated demagnetization, thereby increasing the number of times the slurry is demagnetized, which is beneficial to removing magnetic substances from the slurry to a great extent and improving the quality of the slurry.

[0100] The third valve 33 is configured to control the opening and closing of the passage of the main outlet pipe 23. Optionally, the third valve 33 can be a pneumatic ball valve, or the third valve 33 can also be, but is not limited to, a pneumatic butterfly valve, a pneumatic gate valve, a pneumatic stop valve, and an electric valve.

[0101] The fourth valve 34 is configured to control the opening and closing of the passage of the circulation inlet pipe 25. Optionally, the fourth valve 34 can be a pneumatic ball valve, or the fourth valve 34 can also be, but is not limited to, a pneumatic butterfly valve, a pneumatic gate valve, a pneumatic stop valve, and an electric valve.

[0102] The fifth valve 35 is configured to control the opening and closing of the passage of the circulation outlet pipe 26. Optionally, the fifth valve 35 can be a pneumatic ball valve, or the fifth valve 35 can also be, but is not limited to, a pneumatic butterfly valve, a pneumatic gate valve, a pneumatic stop valve, and an electric valve.

[0103] Please see Figure 4 and Figure 5 In some embodiments, the buffer mechanism 4 further includes a first pump body 42 and a second pump body 43. The first pump body 42 is disposed in the circulation inlet pipe 25 and configured to provide power for the slurry to enter the buffer chamber, and the second pump body 43 is disposed in the circulation outlet pipe 26 and configured to provide power for the slurry to exit the buffer chamber.

[0104] By providing a first pump body 42 and a second pump body 43, it is beneficial to ensure the reliability of slurry entering and exiting the buffer tank 41.

[0105] Optionally, both the first pump body 42 and the second pump body 43 can be configured as diaphragm pumps.

[0106] In some embodiments, the valve control further includes a sixth valve 36, which is connected to the main inlet pipe 21.

[0107] The sixth valve 36 is configured to control the opening and closing of the passage of the main inlet pipe 21. The sixth valve 36 can be a pneumatic ball valve, or it can also be, but is not limited to, a pneumatic butterfly valve, a pneumatic gate valve, a pneumatic stop valve, and an electric valve.

[0108] Optionally, the controller is also electrically connected to the third valve 33, the fourth valve 34, the fifth valve 35 and the sixth valve 36 of the valve control, respectively, and is configured to control the opening and closing of the third valve 33, the fourth valve 34, the fifth valve 35 and the sixth valve 36, respectively.

[0109] In some embodiments, the number of demagnetizing mechanism 1, feeding channel 201, discharging channel 202 and first valve 31 are two, wherein the two first valves 31 are opened and closed alternately.

[0110] In the above technical solution, the demagnetizing device includes two demagnetizing mechanisms 1. Correspondingly, there are two feeding channels 201, two discharging channels 202, and two first valves 31. In the specific use of the demagnetizing device, one of the first valves 31 is opened, and the slurry can enter the demagnetizing mechanism 1 connected to it through one of the feeding channels 201 to carry out demagnetization. When the adsorption element 121 in this demagnetizing mechanism 1 needs to be cleaned, this first valve 31 is closed to carry out cleaning. The other first valve 31 is opened, and the slurry can enter the demagnetizing mechanism 1 connected to it through the other feeding channel 201 to carry out demagnetization.

[0111] By setting it up in the above manner, the two demagnetizing mechanisms 1 can be used alternately during the production process. The two first valves 31 can be used to control the demagnetizing mechanism 1 to demagnetize and the demagnetizing mechanism 1 to clean the magnetic slag. This allows the demagnetizing device to be used without stopping the machine to clean the adsorption component 121, thus achieving high-speed and continuous demagnetization. At the same time, the setting of two demagnetizing mechanisms 1 can also simplify the structure and reduce the volume occupied by the demagnetizing device, thereby helping to reduce costs.

[0112] For ease of description, the following explanation will focus on two demagnetizing mechanisms, 1 and 2.

[0113] Please continue reading. Figure 1 and Figure 2In some embodiments, the demagnetizing mechanism 1 further includes a drive assembly 13. The demagnetizing tank 11 includes a tank body 111 and a cover 112. The tank body 111 has a demagnetizing cavity 101. The cover 112 covers the tank body 111 along the height direction X and has a through hole 1121 communicating with the demagnetizing cavity 101. The drive assembly 13 is connected to the adsorption member 121 and is configured to drive the adsorption member 121 to move along the height direction X to extend or extend into the demagnetizing cavity 101 through the through hole 1121.

[0114] The tank body 111 has a demagnetizing chamber 101, a feed inlet and a discharge outlet, and the cover 112 covers the top of the tank body 111 along the height direction X.

[0115] When demagnetization is required, the drive assembly 13 drives the adsorption element 121 to extend into the demagnetization chamber 101 through the through hole 1121, and uses the magnetic attraction ability of the adsorption element 121 to adsorb magnetic impurities. When it is necessary to clean or replace the adsorption element 121, the drive assembly 13 drives the adsorption element 121 to extend out of the demagnetization chamber 101 through the through hole 1121, which facilitates replacement, maintenance or other operations. This design makes the demagnetization mechanism 1 more flexible and efficient, and can adapt to different demagnetization needs.

[0116] For example, Figure 2 The adsorption element 121 in the demagnetizing mechanism 1 located on the left extends out of the demagnetizing cavity 101, while the adsorption element 121 in the demagnetizing mechanism 1 located on the right extends into the demagnetizing cavity 101, so that the two demagnetizing mechanisms 1 can demagnetize and clean alternately.

[0117] In some embodiments, the drive assembly 13 includes a drive member 131 and a protective cover 132. The protective cover 132 has a protective cavity 1321 and is connected to one side of the demagnetizing tank 11 along the height direction X. The drive member 131 is connected to the side of the protective cover 132 facing away from the demagnetizing tank 11 along the height direction X. The drive member 131 is telescopic to drive the adsorption member 121 to move between the demagnetizing cavity 101 and the protective cavity 1321 along the height direction X.

[0118] In the above technical solution, the protective cover 132 can protect the adsorption member 121 extending out of the demagnetizing cavity 101 to prevent external impurity particles from sticking to the adsorption member 121, thereby preventing contamination of the slurry.

[0119] Alternatively, the drive unit 131 can be configured as a telescopic cylinder.

[0120] Optionally, the controller is also electrically connected to the drive 131, and the controller is also configured to turn the drive 131 on and off.

[0121] Please see Figures 5 to 7In some embodiments, the demagnetizing mechanism 1 further includes a guide sleeve 14, which has a through hole 1401 extending along the height direction X. The guide sleeve 14 is connected to the cover 112, and part of the guide sleeve 14 extends into the demagnetizing cavity 101 through the through hole 1121. The adsorption member 121 extends into or out of the demagnetizing cavity 101 through the through hole 1401.

[0122] The guide sleeve 14 is used to position and guide the adsorption component 121. The phrase "the guide sleeve 14 is connected to the cover 112, and part of the guide sleeve 14 extends into the demagnetizing cavity 101 through the through hole 1121" can be understood as follows: in the height direction X, the size of the guide sleeve 14 is larger than the size of the cover 112, and the size of the sleeve hole 1401 is larger than the size of the through hole 1121. The adsorption component 121 can move through the longer sleeve hole 1401, which helps reduce the risk of the adsorption component 121 deflecting during movement, thereby improving its stability and accuracy in moving along the height direction X. Furthermore, it can reduce the thickness of the cover 112, thus helping to reduce costs.

[0123] Furthermore, by adjusting the shape and size of the sleeve hole 1401 of the guide sleeve 14, it can be adapted to adsorption components 121 of different shapes or sizes, thereby improving the flexibility of the demagnetizing device.

[0124] In some embodiments, the guide sleeve 14 includes a sleeve body 141 and a protrusion 142. The sleeve body 141 extends into the demagnetizing cavity 101 through a through hole 1121 and has a sleeve hole 1401. The protrusion 142 is connected to the side of the sleeve body 141 facing away from the demagnetizing cavity 101 along the height direction X, and protrudes from the sleeve body 141 along the circumferential direction of the sleeve hole 1401 facing away from the sleeve hole 1401. The protrusion 142 is connected to the cover 112.

[0125] like Figure 7 As shown, the protrusion 142 protrudes from the periphery of the sleeve body 141 and connects with the cover body 112 to realize the connection between the guide sleeve 14 and the cover body 112, which facilitates the assembly of the guide sleeve 14. A portion of the sleeve body 141 is disposed in the through hole 1121, which can abut against the cover body 112 and can also be adhered to the cover body 112.

[0126] Optionally, the shape of the sleeve 1401 is the same as that of the sleeve 1401 and is coaxially arranged.

[0127] Optionally, the protrusion 142 can be fixed to the cover 112 by fasteners, which may include, but are not limited to, bolts, screws, studs, etc.

[0128] Please continue reading. Figure 7In some embodiments, the demagnetizing mechanism 1 further includes a scraper 15. The sleeve body 141 has a first groove 1411 communicating with the sleeve hole 1401. The scraper 15 is disposed in the first groove 1411, protruding from the sleeve body 141 toward the sleeve hole 1401 and abutting against the periphery of the adsorption assembly 12. The adsorption assembly 12 has an adsorption state and a cleaning state. In the adsorption state, the adsorption member 121 extends into the demagnetizing cavity 101, and in the cleaning state, the adsorption member 121 extends out of the demagnetizing cavity 101.

[0129] In the above technical solution, when the adsorption component 121 extends out of the demagnetizing cavity 101, the scraper component 15 will abut against the adsorption component 12 to scrape the magnetic material adsorbed on its periphery into the demagnetizing cavity 101 for subsequent cleaning.

[0130] Alternatively, the scraper 15 can be a scraper rubber ring, which will not pose a safety problem to the adsorption component 12.

[0131] In some embodiments, the demagnetizing mechanism 1 further includes a cleaning component connected to the demagnetizing tank 11. In the cleaning state, the cleaning component is configured to introduce a cleaning medium for cleaning magnetic materials into the demagnetizing cavity 101.

[0132] In related technologies, demagnetizing devices are typically cleaned manually, which not only increases labor costs but also compromises the cleanliness of the adsorption element 121, thus affecting the quality of the slurry.

[0133] In contrast, the embodiments of this application use a cleaning component to wash away the magnetic material scraped off by the scraper 15, thereby preventing the accumulation of magnetic material and reducing the demagnetization effect, and reducing labor costs.

[0134] In some alternative embodiments, the controller is also electrically connected to the cleaning component, and the controller is also configured to control the opening and closing of the cleaning component.

[0135] In the above technical solution, the opening and closing of the cleaning components can be controlled by the controller, which can realize the automated design of the demagnetizing device.

[0136] In some alternative embodiments, the adapter 122 is provided with a sensor that is communicatively connected to the cleaning component.

[0137] When the scraper 15 comes into contact with the adapter 122, the sensor can send a cleaning signal to the cleaning component. After receiving the cleaning signal, the cleaning component introduces a cleaning medium for cleaning magnetic materials into the demagnetizing chamber 101 to achieve the self-cleaning function of the demagnetizing device, which helps to improve operating efficiency.

[0138] Please see Figure 5 and Figure 6In some embodiments, there are multiple cleaning components, which are distributed circumferentially along the demagnetizing tank 11. Each cleaning component includes a nozzle 161, which is connected to the side of the tank 111 facing the demagnetizing cavity 101.

[0139] Setting it up in the above way helps to improve the efficiency of cleaning components.

[0140] Optionally, the cleaning component may include a cleaning pipe that is connected to a nozzle 161. N-methylpyrrolidone (NMP) or other cleaning media are introduced into the nozzle 161 through the cleaning pipe, and the nozzle 161 can spray out the cleaning media to clean the demagnetizing cavity 101.

[0141] Please see Figure 8 Optionally, the nozzle 161 can be configured as a fan-shaped structure, that is, four 90° fan-shaped nozzles 161 are evenly arranged circumferentially on the inner wall of the tank 111, so that the high-pressure water sprayed from the nozzle 161 can achieve 360° coverage, so as to wash away the magnetic material attached to the inner wall of the tank 111.

[0142] Please continue reading. Figure 1 and Figure 2 In some embodiments, the demagnetizing tank 11 also has a vent that communicates with the demagnetizing chamber 101, and the connecting pipe assembly also includes a vent pipe 27 that communicates with the vent. The valve control also includes a seventh valve 37 that is connected to the vent pipe 27.

[0143] The seventh valve 37 is configured to control the opening and closing of the passage in the vent pipe 27, thereby achieving precise control of the vent discharge function.

[0144] Specifically, a vent is provided at the bottom of the tank 111. The bottom of the tank 111 can be configured as a conical structure to facilitate the outflow of cleaning medium and magnetic material from the demagnetizing chamber 101.

[0145] The controller is also electrically connected to the seventh valve 37 of the valve control, and the controller is configured to control the opening and closing of the seventh valve 37.

[0146] After the cleaning operation is completed, the controller controls the seventh valve 37 to open, thereby opening the discharge pipe 27. This allows the cleaning medium and magnetic material in the demagnetizing chamber 101 to flow out through the discharge port. When there is no more cleaning medium or magnetic material in the demagnetizing chamber 101, the controller controls the seventh valve 37 to close, thereby closing the discharge pipe 27. This design facilitates the automation of the demagnetizing device's cleaning process, thereby improving operational efficiency and reducing labor costs.

[0147] Optionally, the seventh valve 37 can be a pneumatic ball valve, or the seventh valve 37 can also be, but is not limited to, a pneumatic butterfly valve, a pneumatic gate valve, a pneumatic stop valve, and an electric valve.

[0148] Please see Figures 5 to 7 In some optional embodiments, the adsorption assembly 12 further includes an adapter 122, which is connected to the side of the adsorption member 121 facing the tank 111 along the height direction X. The magnetic attraction capacity of the adsorption member 121 is greater than that of the adapter 122. In the adsorption state, the scraper 15 abuts against the adsorption member 121; in the cleaning state, the scraper 15 abuts against the adapter 122.

[0149] With the above configuration, when the adsorption assembly 12 is in the adsorption state, a portion of the adsorption element 121 abuts against the scraper 15, and the other portion extends into the demagnetizing chamber 101 to adsorb magnetic materials in the slurry. When the adsorption assembly 12 switches from the adsorption state to the cleaning state, the adsorption assembly 12 moves upward along the height direction X, and the scraper 15 abuts against the adsorption element 121 to scrape off the adsorbed magnetic materials. When the scraper 15 abuts against the adapter 122, all the magnetic materials scraped off by the scraper 15 gather on the adapter 122. At this time, the adsorption assembly 12 is in the cleaning state and can be cleaned. Since the magnetic attraction capacity of the adapter 122 is relatively weak, the magnetic materials on the scraper 15 are more likely to fall off naturally or be washed off by the cleaning medium, which helps to improve the efficiency of the demagnetizing device in cleaning magnetic materials.

[0150] By connecting the adapter 122 to the bottom of the adsorption component 121, in the cleaning state, the magnetic material will be gathered by the scraper 15 onto the adapter 122 and then fall off. Since the magnetic attraction of the adapter 122 is relatively weak, it can avoid the situation where the magnetic material is still stuck to its bottom, thereby improving the cleanliness of the adsorption component 12.

[0151] The adapter 122 can be made of a non-magnetic material, which may include, but is not limited to, polytetrafluoroethylene, polyurethane, etc.

[0152] Optionally, the adapter 122 can be fixed to the adsorption member 121 by fasteners, which may include, but are not limited to, bolts, screws, studs, etc.

[0153] Optionally, the adapter 122 and the adsorption member 121 have the same shape to prevent magnetic material scraped off the adsorption member 121 from remaining at the connection between the adsorption member 121 and the adapter 122. For example, both the adapter 122 and the adsorption member 121 can be configured as cylindrical structures.

[0154] In some embodiments, in the cleaned state, a portion of the adapter 122 is located in the sleeve hole 1401, and another portion is located in the demagnetizing cavity 101.

[0155] By setting it in the above manner, it can be ensured that there are no magnetic materials inside the sleeve hole 1401, so as to prevent magnetic material residue.

[0156] Please continue reading. Figures 5 to 7 In some optional embodiments, the demagnetizing mechanism 1 further includes a guide 17, and the sleeve body 141 also has a second groove 1412 communicating with the sleeve hole 1401. The second groove 1412 is disposed on the side of the first groove 1411 facing away from the demagnetizing cavity 101 along the height direction X. The second groove 1412 is provided with the guide 17, and the guide 17 protrudes from the sleeve body 141 toward the sleeve hole 1401 and abuts against the adsorption assembly 12.

[0157] The guide member 17 further guides and limits the movement of the adsorption member 121. Furthermore, by fixing the guide member 17 within the second groove 1412 of the sleeve body 141, the connection stability between the guide member 17 and the sleeve body 141 is improved. It is understood that the adsorption assembly 12 can move up and down along the height direction X under the drive of the drive member 131, which will exert a pulling force on the guide member 17. By placing a portion of the guide member 17 within the second groove 1412 for fixed connection with the sleeve body 141, and having another portion extend out of the second groove 1412 to abut against the adsorption assembly 12, the guide member 17 can both perform its guiding function and prevent displacement or even failure during use, thereby improving the reliability of the demagnetizing device.

[0158] Optionally, the guide 17 can be configured as a full ring structure or as a ring structure with an intermittent structure.

[0159] In order to improve the ability of the guide 17 to provide better limiting for the adsorption assembly 12, the guide 17 can be made of a non-elastic material to prevent the adsorption assembly 12 from squeezing the guide 17 and causing it to wobble during movement.

[0160] For example, the guide 17 can be a nylon guide ring. The nylon guide ring can provide better positioning for the adsorption component 12, so that the adsorption component 12 and the guide sleeve 14 remain concentric during the movement, and it is not easy for the nylon guide ring to deviate. In addition, the nylon guide ring is more wear-resistant and can reduce the wear of the adsorption component 12.

[0161] In some alternative embodiments, there are multiple second slots 1412, and multiple first slots 1411 are distributed at intervals along the height direction X.

[0162] By setting the number of second slots 1412 to multiple, and providing a guide 17 in each second slot 1412, the adsorption assembly 12 can be better guided and limited to prevent it from shifting during movement, thus improving the reliability of the demagnetizing device.

[0163] Please continue reading. Figures 5 to 7 In some alternative embodiments, the demagnetizing mechanism 1 further includes a first sealing ring 18 disposed between the protrusion 142 and the cover 112.

[0164] The first sealing ring 18 can ensure the sealing between the protrusion 142 and the cover 112 to prevent the slurry from flowing out between the protrusion 142 and the cover 112. Furthermore, it can also prevent impurities and other foreign objects in the external environment from entering the demagnetizing cavity 101 between the protrusion 142 and the cover 112, so as to ensure the cleanliness of the environment in the demagnetizing cavity 101 and avoid slurry contamination, thereby improving the reliability of the demagnetizing device.

[0165] The first sealing ring 18 can be an O-ring.

[0166] In some alternative embodiments, the demagnetizing mechanism 1 further includes a second sealing ring 19, and the sleeve body 141 also has a third groove 1413 communicating with the sleeve hole 1401. The third groove 1413 is provided with the second sealing ring 19. The third groove 1413 is located on the side of the first groove 1411 facing away from the demagnetizing cavity 101 along the height direction X, and the second sealing ring 19 protrudes from the sleeve body 141 toward the sleeve hole 1401 and abuts against the adsorption assembly 12.

[0167] The second sealing ring 19 can ensure the sealing between the sleeve body 141 and the adsorption component 12 to prevent the slurry from flowing out between the sleeve body 141 and the adsorption component 12. Furthermore, it can also prevent impurities and other foreign objects in the external environment from entering the demagnetization chamber 101 between the sleeve body 141 and the adsorption component 12, so as to ensure the cleanliness of the environment in the demagnetization chamber 101 and avoid slurry contamination, thereby improving the reliability of the demagnetization device.

[0168] Furthermore, by fixing the second sealing ring 19 within the third groove 1413 of the sleeve body 141, the connection stability between the second sealing ring 19 and the sleeve body 141 is improved. It is understood that the adsorption assembly 12 can move up and down along the height direction X under the drive of the drive member 131, which will exert a pulling force on the second sealing ring 19. By placing a portion of the second sealing ring 19 within the third groove 1413 to be fixedly connected to the sleeve body 141, and having another portion extend out of the third groove 1413 to abut against the adsorption assembly 12, the sealing function of the second sealing ring 19 can be guaranteed, and displacement or even failure during use can be prevented, thereby improving the reliability of the demagnetizing device.

[0169] In order to better improve the sealing performance of the demagnetizing mechanism 1, the second sealing ring 19 can be set as a lip seal.

[0170] like Figure 7 As shown, for example, there are two second slots 1412 and two guide members 17. In the height direction X, the second slot 1412 and the third slot 1413 are respectively located on the side of the first slot 1411 facing away from the demagnetizing cavity 101, and the third slot 1413 is located between the two second slots 1412.

[0171] In some alternative embodiments, the demagnetizing mechanism 1 further includes a level gauge 20, and each demagnetizing tank 11 is connected to a level gauge 20, which is configured to detect the level of the slurry in the demagnetizing chamber 101.

[0172] The controller is electrically connected to the level gauge 20 and is configured to control the opening and closing of the level gauge 20.

[0173] The demagnetizing device provided in this application embodiment can have two demagnetizing modes: one is capable of single-pass demagnetization, which is beneficial for improving demagnetizing efficiency and enabling rapid production; the other is capable of repeated demagnetization, which is beneficial for improving the purity of the slurry. In specific use, the demagnetizing state can be adjusted by controlling the valve control according to requirements.

[0174] The process of a single demagnetization mode is, for example, as follows: Figures 1 to 7 As shown, in the control diagram, the drive unit 131 on the left extends to drive the adsorption unit 121 into the demagnetizing chamber 101, opening the sixth valve 36, the first valve 31 on the left, the second valve 32 on the left, and the third valve 33, allowing the slurry to enter the demagnetizing tank 11 on the left side of the diagram through the main inlet pipe 21 and the sub-inlet pipe 22 for demagnetization, and then being discharged to the next process through the sub-outlet pipe 24 and the main outlet pipe 23. When the adsorption unit 121 on the left has a lot of magnetic material adhering to it, resulting in poor demagnetization effect, the drive unit 131 on the right side of the control diagram extends to drive the adsorption unit 121 into the demagnetizing chamber 101, and closes the first valve 31 and the second valve 32 on the left, while opening the first valve 31 and the second valve 32 on the right, allowing the slurry to enter the demagnetizing tank 11 on the right side of the diagram for demagnetization. In the control diagram, the drive unit 131 on the left retracts to drive the adsorption unit 121 to extend out of the demagnetizing chamber 101. The scraper unit 15 scrapes the magnetic material adsorbed on the adsorption unit 121 into the demagnetizing chamber 101. The cleaning mechanism automatically opens to spray cleaning medium for cleaning magnetic materials into the demagnetizing chamber 101 through the nozzle 161, thereby flushing off the magnetic materials adhering to the inner wall of the demagnetizing tank 11. The seventh valve 37 is opened, allowing the cleaning medium and magnetic materials to be discharged through the vent and vent pipe 27. By repeatedly switching in this manner, the function of demagnetizing one demagnetizing tank 11 and cleaning another demagnetizing tank 11 can be achieved, enabling continuous and efficient demagnetization.

[0175] The process of repeated demagnetization mode is, for example, as follows: Figures 2 to 7 As shown, the drive unit 131 on the left side of the control diagram extends to drive the adsorption unit 121 into the demagnetizing chamber 101, opening the sixth valve 36, the first valve 31 on the left side, the second valve 32 on the left side, the fourth valve 34, and the first pump body 42. This allows the slurry to enter the demagnetizing tank 11 on the left side of the diagram through the main inlet pipe 21 and the sub-inlet pipe 22 for demagnetization, and then enter the buffer tank 41 through the sub-outlet pipe 24 and the circulation inlet pipe 25. When the slurry in the buffer tank 41 reaches the preset liquid level, the sixth valve 36 and the first valve 31 on the left side are closed. The first pump body 42 will pump the remaining slurry in the demagnetizing tank 11 on the left side into the buffer tank 41. When the slurry in the demagnetizing tank 11 on the left side drops to the preset liquid level, the second valve 32 on the left side and the first pump body 42 are closed. In the control diagram, the drive unit 131 on the right extends to drive the adsorption unit 121 into the demagnetizing chamber 101, opening the fifth valve 35, the first valve 31 on the right, the second pump body 43, and the slurry in the buffer tank 41. The slurry then enters the demagnetizing tank 11 on the right for demagnetization and continues to flow back into the buffer tank 41, repeating this process. When the purity of the slurry meets the requirements, the fourth valve 34 is closed and the third valve 33 is opened to discharge the slurry.

[0176] Among them, the valve control, drive component 131, first pump body 42, second pump body 43, cleaning mechanism and level gauge 20 are all controlled by programmable logic controllers to realize the automatic demagnetization and automatic cleaning functions of the demagnetizing device.

[0177] Secondly, this application also provides a battery production apparatus, including a demagnetizing device according to any embodiment of the first aspect, the demagnetizing device being configured to remove magnetic materials from battery slurry.

[0178] Because the demagnetizing device provided in this application embodiment can effectively demagnetize the battery slurry while cleaning the adsorption component 12, the battery production equipment can continue production, which helps to improve the efficiency of the battery production equipment.

[0179] Please refer to the following: Figures 2 to 7 According to some embodiments of this application, this application provides a demagnetizing device, including a demagnetizing mechanism 1, a connecting pipe assembly, a valve control, a controller, and a buffer mechanism 4.

[0180] Two demagnetizing mechanisms 1 are provided. Each demagnetizing mechanism 1 includes a demagnetizing tank 11, an adsorption component 12, a driving component 13, a guide sleeve 14, a scraper component 15, a cleaning component, a guide component 17, a first sealing ring 18, and a second sealing ring 19. The demagnetizing tank 11 includes a tank body 111 and a cover 112. The tank body 111 has a demagnetizing cavity 101 and an inlet, an outlet, and a vent that are respectively connected to the demagnetizing cavity 101. The cover 112 covers the tank body 111 along the height direction X of the demagnetizing tank 11 and has a through hole 1121 that is connected to the demagnetizing cavity 101.

[0181] The guide sleeve 14 includes a sleeve body 141 and a protrusion 142. The sleeve body 141 has a sleeve hole 1401 extending through the sleeve in the height direction X and extending into the demagnetizing cavity 101 through a through hole 1121.
