[0001] The utility model relates to the technical field of battery production, and particularly relates to a magnetic separator, a magnetic iron removing device and a battery production line. Background Art

[0002] In the process of lithium battery production, a magnetic separator is used to remove ferromagnetic impurities in the battery slurry to avoid the influence of ferromagnetic impurities on the battery performance. A magnetic bar is arranged in the magnetic separator, and the magnetic bar is inserted into the battery slurry to adsorb the ferromagnetic impurities in the battery slurry. In order to ensure the cleaning effect of the magnetic bar on the impurities, the ferromagnetic impurities adsorbed on the magnetic bar need to be cleaned regularly. At present, the magnetic bar is usually cleaned manually, and the operation is relatively inconvenient. Summary of the Utility Model

[0003] The main purpose of the utility model is to propose a magnetic separator, a magnetic iron removing device and a battery production line, aiming to improve the cleaning convenience of the magnetic bar in the magnetic separator.

[0004] To achieve the above purpose, the magnetic separator proposed by the utility model includes:

[0005] A tank body, the tank body is provided with an open magnetic iron removing cavity;

[0006] A magnetic bar assembly, the magnetic bar assembly includes a cover body and a magnetic bar, the cover body covers the opening, and the magnetic bar is arranged on the side of the cover body facing the magnetic iron removing cavity;

[0007] A driving assembly, the driving assembly is connected with the magnetic bar assembly and is used for driving the magnetic bar assembly to approach or move away from the tank body so that the magnetic bar enters and exits the magnetic iron removing cavity; and

[0008] A cleaning assembly, the cleaning assembly includes a cleaning module and a moving mechanism, the cleaning module includes a cleaning slip ring and a sealing ring arranged inside the cleaning slip ring, the magnetic bar penetrates through the cleaning slip ring and the sealing ring and is attached to the sealing ring, the moving mechanism is used for driving the cleaning module to slide along the magnetic bar, the cleaning slip ring includes two semi-ring structures that are spliced together, and the cleaning module further includes a tightening member that is fastened on the outer sides of the two semi-ring structures.

[0009] In the electromagnetic separator according to the embodiments of the present application, a cleaning assembly for cleaning the magnetic rod is provided. When the magnetic rod needs to be cleaned, the driving assembly drives the magnetic rod assembly to move so that the magnetic rod assembly is separated from the tank body. The moving mechanism of the cleaning assembly drives the cleaning module to slide, so that the sealing ring of the cleaning module scrapes off the ferromagnetic impurities adhered to the magnetic rod, realizing the cleaning of the magnetic rod. This setting method can realize the automatic cleaning of the magnetic rod in the electromagnetic separator without manual participation, improving the convenience of magnetic rod cleaning. The cleaning slip ring is composed of two connected half-ring structures, and is fastened by a fastening member to stably join the two half-ring structures, and is convenient for disassembly and assembly.

[0010] In some embodiments, the cleaning module further includes a connection disk, the connection disk is provided with an installation opening, the cleaning slip ring is fixed in the installation opening, and the connection disk is connected to the moving mechanism.

[0011] With this setting method, multiple cleaning slip rings can be installed on the connection disk for cleaning multiple magnetic rods, enabling the moving mechanism to drive multiple cleaning slip rings to move synchronously, with a simple structure and high cleaning efficiency.

[0012] In some embodiments, a card slot is provided on the outer side wall of the cleaning slip ring, and a partial structure of the connection disk located on the periphery of the installation opening is clamped in the card slot.

[0013] With this setting method, the connection strength between the cleaning slip ring and the connection disk is relatively high, and the connection disk limits the cleaning slip ring in the sliding direction of the cleaning module, preventing the cleaning slip ring from moving relative to the connection disk or falling off the connection disk, and improving the overall structural stability of the cleaning module.

[0014] In some embodiments, a limiting groove is provided on the outer side wall of the half-ring structure, and the fastening member is clamped in the limiting groove.

[0015] With this setting method, it can be avoided that the fastening member moves along the axial direction of the cleaning slip ring and causes it to detach from the cleaning slip ring, improving the connection strength between the fastening member and the cleaning slip ring and the overall structural stability.

[0016] In some embodiments, the moving mechanism includes:

[0017] a driving member, which is arranged on the side of the cover body facing away from the tank body; and

[0018] a connecting rod, the connecting rod penetrates through the cover body, one end of the connecting rod is connected to the driving member, the other end of the connecting rod is connected to the cleaning module, and the driving member is used to drive the connecting rod to move up and down.

[0019] In this setting method, the driving member of the moving mechanism is arranged outside the iron removal cavity, which can avoid the influence of the battery slurry on the driving member; and the driving member does not occupy space in the iron removal cavity and on the cover body, which can reduce the volume of the tank body and the cover body.

[0020] In some embodiments, the driving assembly includes:

[0021] A mounting rack, the mounting rack is located above the tank body, and the cover body is arranged on the mounting rack; and

[0022] A lifting mechanism, the lifting mechanism is arranged on the side of the tank body and is connected to the mounting rack, and the lifting mechanism is configured to drive the mounting rack to lift and lower.

[0023] In this setting method, the driving assembly drives the magnetic rod assembly to lift and lower so that the magnetic rod assembly is separated from or connected to the tank body. The movement mode of the magnetic rod assembly is relatively simple, the overall structure is concise, and it is convenient to control.

[0024] In some embodiments, the tank body is provided with a first connection part, and the magnetic rod assembly is provided with a second connection part. The second connection part is located on the side of the cover body facing the tank body;

[0025] When the cover body covers the tank body, the first connection part and the second connection part cooperate with each other to connect the tank body and the cover body.

[0026] This setting method can improve the connection strength between the magnetic rod assembly and the tank body, so that the cover body and the tank body are tightly connected, improve the sealing performance of the iron removal cavity, and reduce the risk of liquid leakage from the tank body and external impurities entering the iron removal cavity.

[0027] In some embodiments, the second connection part and the cover body are arranged at intervals, and the magnetic rod assembly further includes a connecting piece connecting the cover body and the second connection part;

[0028] The iron remover further includes a rotating mechanism, and the rotating mechanism is used to drive the magnetic rod assembly to rotate so that the first connection part and the second connection part are clamped or separated. When the first connection part and the second connection part are clamped, the second connection part is located on the side of the first connection part facing away from the cover body.

[0029] In this setting method, when the cover body covers the tank body, the magnetic rod assembly is driven to rotate by a rotating mechanism so that the first connecting portion enters and exits the area between the second connecting portion and the cover body. When the first connecting portion is clamped between the second connecting portion and the cover body, the magnetic rod assembly is locked with the tank body, and the magnetic rod assembly cannot be directly detached from the tank body above the tank body, thus improving the reliability of the connection between the magnetic rod assembly and the tank body. When it is necessary to enable the magnetic rod assembly to move freely along the height direction of the tank body, the first connecting portion and the second connecting portion can be misaligned by driving the magnetic rod assembly to rotate through the rotating mechanism. The structure is simple and the operation is convenient.

[0030] In some embodiments, the first connecting portion is set as one of a wedge block and a rolling member, and the second connecting portion is set as the other of the wedge block and the rolling member. When the first connecting portion and the second connecting portion are clamped or separated, the rolling member rolls along the wedge block.

[0031] In this setting method, the contact between the first connecting portion and the second connecting portion is a point contact, and it is a rolling friction when the first connecting portion and the second connecting portion are clamped or separated. This can not only reduce the friction between the magnetic rod assembly and the tank body when the magnetic rod assembly rotates, but also reduce the problem of impurity particles generated due to friction.

[0032] In some embodiments, one of the first connecting portion and the second connecting portion is provided with an inclined surface for abutting against the other, and the inclined surface is inclined along the rotation and clamping direction of the magnetic rod assembly and along the arrangement direction of the cover body and the tank body.

[0033] In this setting method, when the magnetic rod assembly is rotated to clamp the first connecting portion and the second connecting portion, the second connecting portion can move downward under the guidance of the inclined surface, thereby driving the cover body to move toward the tank body, making the cover body tightly fastened to the tank body, improving the sealing performance of the iron removal cavity, and reducing the risk of liquid leakage from the tank body and external impurities entering the iron removal cavity.

[0034] In some embodiments, the material of the first connecting portion is a non-metallic material;

[0035] and / or, the material of the second connecting portion is a non-metallic material.

[0036] In this setting method, the first connecting portion and the second connecting portion will not generate ferromagnetic impurities due to friction, thereby reducing the risk of ferromagnetic particles generated by the iron remover itself.

[0037] In some embodiments, the iron remover further includes a liquid leakage detection assembly, and the liquid leakage detection assembly is configured to detect the liquid leakage state of the tank body.

[0038] In this setting method, the liquid leakage detection assembly can be used to detect whether there is a liquid leakage problem in the tank body, so as to deal with it in time when there is a liquid leakage, and avoid the leakage of battery slurry from affecting the operation of the equipment and polluting the environment.

[0039] In some embodiments, a liquid leakage tray is provided on the outer side of the tank body for receiving the slurry overflowing from the tank body, and the liquid leakage tray is provided with a liquid discharge port;

[0040] The liquid leakage detection assembly includes a liquid receiving box and a liquid leakage detection belt. The liquid receiving box is arranged below the liquid discharge port, and the liquid leakage detection belt is arranged in the liquid receiving box.

[0041] In this setting method, when there is a problem of liquid leakage in the tank body, the battery slurry overflowing from the tank body first flows into the liquid leakage tray, and then flows into the liquid receiving box of the liquid leakage detection tray through the liquid discharge port of the liquid leakage tray to trigger the liquid leakage detection belt, so that the liquid leakage detection assembly emits an induction signal; it can not only ensure that the liquid leakage detection assembly can detect the liquid leakage problem in time when the tank body leaks, but also avoid the overflowing battery slurry from flowing to the area outside the liquid leakage detection assembly through the setting of the liquid leakage tray and the liquid receiving box, preventing the battery slurry from leaking and affecting the operation of the equipment and polluting the environment.

[0042] In some embodiments, the iron remover is provided with a plurality of the tank bodies, and the liquid leakage trays are provided on the outer sides of all the tank bodies;

[0043] Wherein, two adjacent liquid leakage trays are arranged in a stepped manner. The liquid leakage tray located at a lower position is arranged below the liquid discharge port of the liquid leakage tray located at a higher position, and the liquid receiving box is arranged below the liquid discharge port of the liquid leakage tray located at the lower position;

[0044] And / or, the liquid discharge ports of two adjacent liquid leakage trays are located above the same liquid receiving box.

[0045] By adopting the above methods, the liquids in two adjacent liquid leakage trays can be discharged into the same liquid receiving box, thereby reducing the number of liquid leakage detection devices in the iron remover and simplifying the structure.

[0046] The present application also provides an iron removal device, including:

[0047] The iron remover as described in any one of the foregoing embodiments; and

[0048] A collection mechanism, the collection mechanism includes a moving component and a dirt collection member arranged on the moving component, and the moving component is used to drive the dirt collection member to move;

[0049] After the magnetic bar of the iron remover is pulled out from the iron removal cavity, the moving component can drive the dirt collection member to move below the magnetic bar.

[0050] The iron removal device of the present application is composed of an iron remover and a collection mechanism. When cleaning the magnetic rod, ferromagnetic impurities and battery slurry scraped off from the magnetic rod can be collected by the collection mechanism and transported to the recycling and treatment location, further improving the automation and convenience of the cleaning operation.

[0074] During the production process of lithium batteries, a magnetic separator is used to remove ferromagnetic impurities in the battery slurry to avoid the influence of ferromagnetic impurities on the battery performance. A magnetic rod is provided in the magnetic separator, and the magnetic rod is inserted into the battery slurry to adsorb ferromagnetic impurities in the battery slurry. To ensure the cleaning effect of the magnetic rod on the impurities, it is necessary to regularly clean the ferromagnetic impurities adsorbed on the magnetic rod. Currently, the magnetic rod is usually cleaned manually, and the operation is relatively inconvenient.

[0075] Based on the above considerations, the present utility model proposes a magnetic separator 100, which can achieve the effect of automatically cleaning the magnetic rod 22 on the magnetic separator 100, thereby improving the cleaning convenience of the magnetic rod 22 in the magnetic separator 100.

[0076] Please refer to Figure 1 and Figure 2 ,Figure 1 Structural diagram of the iron remover 100 provided according to some embodiments of the present application Figure 2 State diagram of the iron removal device 1000 provided according to some embodiments of the present application when cleaning the magnetic rod 22

[0077] According to some embodiments of the present application, the iron remover 100 includes a tank body 10, a magnetic rod assembly 20, a driving assembly 30, and a cleaning assembly 40. The tank body 10 is provided with an iron removal cavity and an open mouth 11 communicating with the iron removal cavity; the magnetic rod assembly 20 includes a cover body 21 and a magnetic rod 22. The cover body 21 covers the open mouth 11, and the magnetic rod 22 is arranged on the side of the cover body 21 facing the iron removal cavity.

[0078] The driving assembly 30 is connected to the magnetic rod assembly 20 and is used to drive the magnetic rod assembly 20 to approach or move away from the tank body 10, so that the magnetic rod 22 enters and exits the iron removal cavity; the cleaning assembly 40 includes a cleaning module 41 and a moving mechanism 42. The cleaning module 41 includes a cleaning slip ring 411 and a sealing ring 412 arranged inside the cleaning slip ring 411. The magnetic rod 22 passes through the cleaning slip ring 411 and the sealing ring 412 and fits with the sealing ring 412. The moving mechanism 42 is used to drive the cleaning module 41 to slide along the magnetic rod 22. The cleaning slip ring 411 includes two semi-ring structures 4111 that are spliced together. The cleaning module 41 further includes a tightening member 414, and the tightening member 414 is fastened to the outside of the two semi-ring structures 4111.

[0079] In the embodiments of the present application, the tank body 10 of the iron remover 100 serves as a container for accommodating battery slurry and is provided with an iron removal cavity. The tank body 10 can be, but is not limited to, a cylinder, a cuboid, or other shapes. The magnetic rod assembly 20 includes a cover body 21 and a magnetic rod 22. The cover body 21 is used to seal the open mouth 11 of the tank body 10 to seal the iron removal cavity and prevent the battery slurry contained in the iron removal cavity from leaking. The magnetic rod 22 is a rod with magnetism. The cross-section of the magnetic rod 22 can be circular, elliptical, triangular, quadrilateral, or other regular and irregular shapes; the magnetic rod 22 is connected to the side of the cover body 21 facing the iron removal cavity. When the cover body 21 is covered on the tank body 10, the magnetic rod 22 is inserted into the iron removal cavity to adsorb ferromagnetic particles doped in the battery slurry contained in the iron removal cavity.

[0080] The driving component 30 is at least used to drive the lifting of the magnetic rod component 20. When the magnetic rod component 20 rises, the cover body 21 moves away from the tank body 10 to open the iron removal cavity, and the magnetic rod 22 is withdrawn from the iron removal cavity for cleaning; when the magnetic rod component 20 descends, the magnetic rod 22 is inserted into the iron removal cavity, and the cover body 21 covers the open mouth 11 of the tank body 10 to seal the iron removal cavity. Optionally, the driving component 30 can be set as a lifting cylinder or other lifting structures, or can be set as a pulling structure located above the cover body 21, which is not limited herein. Optionally, in some embodiments, the driving component 30 can further include a translation mechanism for driving the magnetic rod component 20 to translate, and the magnetic rod component 20 can be moved away from above the tank body 10.

[0081] In the iron remover 100 in the embodiment of the present application, a cleaning component 40 for cleaning the magnetic rod 22 is further provided. The cleaning component 40 includes a cleaning module 41 and a moving mechanism 42 for driving the cleaning module 41 to slide along the magnetic rod 22. The cleaning module 41 includes a cleaning slip ring 411 and a sealing ring 412. The cleaning slip ring 411 is provided with a through hole for the magnetic rod 22 to pass through, and the sealing ring 412 is arranged on the hole wall. The sealing ring 412 is made of non-metallic material, which can be but is not limited to rubber, silicone rubber, polyurethane rubber, plastic or silica gel and other materials. The magnetic rod 22 passes through the through hole of the cleaning slip ring 411 and the sealing ring 412 arranged in the through hole, and the sealing ring 412 fits on the surface of the magnetic rod 22. Optionally, when the magnetic rod 22 does not need to be cleaned, the moving mechanism 42 drives the cleaning module 41 to move to one end of the magnetic rod 22 close to the cover body 21; when the magnetic rod 22 needs to be cleaned, the moving mechanism 42 drives the cleaning module 41 to move to one end of the magnetic rod 22 away from the cover body 21, so that the cleaning module 41 can scrape off the impurities adsorbed on the surface of the magnetic rod 22 during the moving process. The non-metallic sealing ring 412 can not only prevent the cleaning module 41 from being adsorbed by the magnetic rod 22, resulting in too much resistance during the sliding process, but also avoid the cleaning module 41 from wearing the magnetic rod 22, and avoid mutual wear between the cleaning module 41 and the magnetic rod 22 to generate ferromagnetic particles.

[0082] In this embodiment, the cleaning slip ring 411 is composed of two half-ring structures 4111. The two half-ring structures 4111 enclose to form a through hole for passing the magnetic rod 22. The two half-ring structures 4111 are tightened by a tightening member 414 to make the two half-ring structures 4111 stably spliced. The structure is simple and the disassembly and assembly are convenient. Optionally, the tightening member 414 can be set as but is not limited to a snap ring, a binding band, etc.

[0083] In some embodiments, two or more tightening members 414 may be hoop-mounted on the outer side of the cleaning slip ring 411. Optionally, the cleaning module 41 further includes a connection disk 413. The cleaning slip ring 411 is installed in the installation opening of the connection disk 413, such that the two tightening members 414 hoop-mounted on the cleaning slip ring 411 are respectively located on the two opposite sides of the connection disk 413, and the outer contour dimension of the tightening member 414 is greater than the cross-sectional dimension of the installation opening, so as to mutually limit the cleaning slip ring 411 and the connection disk 413 by means of the two tightening members 414 and prevent the cleaning slip ring 411 from sliding along the axial direction of the installation opening.

[0084] Optionally, the moving mechanism 42 may be directly connected to the cleaning slip ring 411, or may be connected to the connection disk 413 for installing the cleaning slip ring 411 as in the following embodiments. Optionally, the moving mechanism 42 may be configured as a cylinder or a hydraulic cylinder pushing mechanism, and the piston rod of the cylinder or the hydraulic cylinder is connected to the cleaning module 41. Alternatively, the moving mechanism 42 may use a driving motor as the driving member 421. The moving mechanism 42 may be provided with a lead screw for connecting the driving motor and the cleaning module 41. The output shaft of the driving motor is connected to the lead screw for driving the lead screw to rotate. The lead screw is in threaded connection with the cleaning module 41, so as to drive the cleaning module 41 to slide along the magnetic bar 22 when the lead screw rotates. Of course, the driving motor and the cleaning module 41 may also be connected through other transmission mechanisms, such as a connecting rod transmission mechanism, a rack and pinion transmission mechanism, etc.

[0085] Optionally, multiple magnetic bars 22 may be provided in the iron remover 100 to improve the efficiency of removing impurities from the battery slurry in the iron removal chamber. Corresponding multiple cleaning slip rings 411 and sealing rings 412 are provided in the cleaning module 41, and each magnetic bar 22 passes through the corresponding cleaning slip ring 411 and sealing ring 412.

[0086] In specific applications, under the working condition that the magnetic bar 22 needs to be cleaned, the driving assembly 30 drives the magnetic bar assembly 20 to move so that the magnetic bar assembly 20 is separated from the tank body 10, and the moving mechanism 42 of the cleaning assembly 40 drives the cleaning module 41 to slide, so that the sealing ring 412 of the cleaning module 41 scrapes off the ferromagnetic impurities adhered to the magnetic bar 22, realizing the cleaning of the magnetic bar 22. This setting method can realize the automatic cleaning of the magnetic bar 22 in the iron remover 100 without manual participation, improving the convenience of cleaning the magnetic bar 22.

[0087] Please refer to Figure 3 and Figure 5 In some embodiments, the cleaning module 41 further includes a connection disk 413. The connection disk 413 is provided with an installation opening, the cleaning slip ring 411 is fixed in the installation opening, and the connection disk 413 is connected to the moving mechanism 42.

[0088] In this embodiment, the cleaning module 41 includes a connection disk 413 for installing the cleaning slip ring 411. A plurality of cleaning slip rings 411 can be installed on the connection disk 413 to correspond to the cleaning of a plurality of magnetic rods 22, enabling the moving mechanism 42 to drive the plurality of cleaning slip rings 411 to move synchronously. The structure is simple and the cleaning efficiency is high. Among them, the connection disk 413 is provided with an installation opening for installing the cleaning slip ring 411, and a part of the structure of the cleaning slip ring 411 is embedded in the installation opening. The connection method between the cleaning slip ring 411 and the connection disk 413 can be the snap connection in the following embodiments; or the installation opening can be set as a threaded hole so that the cleaning slip ring 411 is threadedly connected to the installation opening; of course, the cleaning slip ring 411 and the connection disk 413 can also be connected by a connecting member 24 such as a bolt, which is not limited herein.

The jacking mechanism 32 can be set as a cylinder or a hydraulic cylinder jacking mechanism, or can be set as but not limited to a motor lead screw mechanism or a scissor lift structure, etc. The mounting frame 31 is connected to the jacking mechanism 32 and can be driven by the jacking mechanism 32 to lift and lower, so as to drive the magnetic rod assembly 20 to lift and lower; so that the magnetic rod assembly 20 is separated from or connected to the tank body 10. The movement mode of the magnetic rod assembly 20 is relatively simple, the overall structure is concise, and it is convenient to control.

[0099] In some embodiments, the moving mechanism 42 is disposed on the mounting frame 31. With this arrangement, the mounting frame 31 can drive the cleaning assembly 40 and the magnetic bar assembly 20 to lift and lower together, keeping the relative positions of the cleaning assembly 40 and the magnetic bar assembly 20 stable, and making the overall structure of the magnetic bar assembly 20, the cleaning assembly 40, and the mounting frame 31 compact.

[0100] Please refer to Figure 1 and Figure 2 , the driving assembly 30 is provided with two sets of lifting mechanisms 32, and the two sets of lifting mechanisms 32 are respectively located on both sides of the tank body 10.

[0101] With this arrangement, the mounting frame 31 is controlled to lift and lower by the two sets of lifting mechanisms 32, which can improve the stability of the mounting frame 31 during the lifting process, avoid the mounting frame 31 from tilting due to uneven force, and ensure that the cover body 21 can accurately align with the tank body 10 for opening and closing.

[0102] Combined with reference to Figure 2 , Figure 4 and Figure 7 , in some embodiments, the tank body 10 is provided with a first connection portion 12, and the magnetic bar assembly 20 is provided with a second connection portion 23. The second connection portion 23 is located on the side of the cover body 21 facing the tank body 10; when the cover body 21 covers the tank body 10, the first connection portion 12 and the second connection portion 23 cooperate with each other to connect the tank body 10 and the cover body 21.

[0103] In this embodiment, the first connection portion 12 is provided on the tank body 10, and the second connection portion 23 corresponding to the first connection portion 12 is provided on the magnetic bar assembly 20. The tank body 10 and the magnetic bar assembly 20 can be connected through the first connection portion 12 and the second connection portion 23. Among them, the first connection portion 12 and the second connection portion 23 can be set as a snap structure that cooperates with each other, or the first connection portion 12 is set as an internal thread on the inner wall of the tank body 10, and the second connection portion 23 is set as an external thread on the side wall of the cover body 21 to thread-connect the tank body 10 and the cover body 21; alternatively, the first connection portion 12 can be set as an external thread on the outer wall of the tank body 10, and the second connection portion 23 can be set as an internal thread hole provided on the cover body 21. Of course, it can also be set as a magnetic attraction connection structure or other structures. With this arrangement, the connection strength between the magnetic bar assembly 20 and the tank body 10 can be improved, so that the cover body 21 is tightly connected to the tank body 10, the sealing performance of the iron removal chamber is improved, and the risk of liquid leakage from the tank body 10 and external impurities entering the iron removal chamber is reduced.

[0104] Combined with reference to Figure 4 and Figure 7, in some embodiments, the second connecting portion 23 and the cover body 21 are spaced apart, and the magnetic bar assembly 20 further includes a connecting member 24 connecting the cover body 21 and the second connecting portion 23; the iron remover 100 further includes a rotating mechanism for driving the magnetic bar assembly 20 to rotate so that the first connecting portion 12 and the second connecting portion 23 are engaged or separated. When the first connecting portion 12 and the second connecting portion 23 are engaged, the second connecting portion 23 is located on the side of the first connecting portion 12 facing away from the cover body 21.

[0105] In this embodiment, the second connecting portion 23 is connected to the cover body 21 through the connecting member 24. The connecting member 24 can be set as a strip structure, a block structure or a border surrounding the cover body 21 along the circumferential direction; the second connecting portion 23 is connected to the connecting member 24 to be spaced apart from the cover body 21, so that a clamping space can be formed between the second connecting portion 23 and the cover body 21. When the cover body 21 covers the tank body 10, the rotating mechanism is used to drive the magnetic bar assembly 20 to rotate so that the first connecting portion 12 enters and exits the area between the second connecting portion 23 and the cover body 21. When the first connecting portion 12 is clamped between the second connecting portion 23 and the cover body 21, the magnetic bar assembly 20 is locked with the tank body 10, and the magnetic bar assembly 20 cannot be directly separated from the tank body 10 from above the tank body 10, improving the reliability of the connection between the magnetic bar assembly 20 and the tank body 10. When it is necessary to enable the magnetic bar assembly 20 to move freely along the height direction of the tank body 10, the rotating mechanism can be used to drive the magnetic bar assembly 20 to rotate so that the first connecting portion 12 is misaligned with the second connecting portion 23. The structure is simple and the operation is convenient.

[0106] Optionally, both the second connecting portion 23 and the first connecting portion 12 can be set as block structures, or, in the following embodiments, one of the first connecting portion 12 and the second connecting portion 23 is set as a wedge block and the other is set as a roller, which is not limited herein.

[0107] Please refer to Figure 7 , in some embodiments, the first connecting portion 12 is set as one of a wedge block and a rolling member 231, and the second connecting portion 23 is set as the other of the wedge block and the rolling member 231. When the first connecting portion 12 and the second connecting portion 23 are engaged or separated, the rolling member 231 rolls along the wedge block.

[0108] In this embodiment, the first connecting portion 12 can be set as the rolling member 231 and the second connecting portion 23 can be set as the wedge block; or the first connecting portion 12 can be set as the wedge block and the second connecting portion 23 can be set as the rolling member 231; the rolling member 231 can be set as but not limited to structures such as rollers and rolling bearings. In this setting method, the contact between the first connecting portion 12 and the second connecting portion 23 is a point contact, and it is a rolling friction when the first connecting portion 12 and the second connecting portion 23 are engaged or separated, which can not only reduce the friction between the magnetic bar assembly 20 and the tank body 10 when the magnetic bar assembly 20 rotates, but also reduce the problem of impurity particles generated due to friction.

[0109] Please refer to Figure 7 In some embodiments, the first connecting portion 12 is provided with an inclined surface 121 for abutting against the second connecting portion 23. The inclined surface 121 is inclined along the rotation and clamping direction of the magnetic rod assembly 20 and along the arrangement direction of the cover body 21 and the tank body 10.

[0110] Specifically, both the first connecting portion 12 and the second connecting portion 23 can be set as block structures. At this time, the abutting surface of the first connecting portion 12 for abutting against the second connecting portion 23 can be set as the inclined surface 121; or the abutting surface of the second connecting portion 23 for abutting against the first connecting portion 12 can be set as the inclined surface 121; or, both the abutting surface of the first connecting portion 12 and the abutting surface of the second connecting portion 23 are set as the inclined surface 121. In some embodiments, one of the first connecting portion 12 and the second connecting portion 23 is set as a wedge block, and the other is set as a rolling member 231, and the inclined surface 121 can be provided on the wedge block. The inclined surface 121 is inclined along the rotation and clamping direction of the magnetic rod assembly 20 and along the arrangement direction of the cover body 21 and the tank body 10. When the magnetic rod assembly 20 is rotated to engage the first connecting portion 12 and the second connecting portion 23, the second connecting portion 23 can move downward under the guidance of the inclined surface 121, thereby driving the cover body 21 to move toward the tank body 10, so that the cover body 21 is tightly fastened to the tank body 10, improving the sealing performance of the iron removal cavity, and reducing the risk of liquid leakage from the tank body 10 and external impurities entering the iron removal cavity.

[0111] In some embodiments, the material of the first connecting portion 12 is a non-metallic material; and / or, the material of the second connecting portion 23 is a non-metallic material.

[0112] In this embodiment, at least one of the first connecting portion 12 and the second connecting portion 23 is made of a non-metallic material; optionally, the non-metallic material can be, but is not limited to, plastic, silica gel, wood or other materials. In this way of setting, the first connecting portion 12 and the second connecting portion 23 will not generate ferromagnetic impurities during friction, thereby reducing the risk of the iron remover 100 itself generating ferromagnetic particles.

[0113] Please refer to Figure 1 and Figure 2 In some embodiments, the iron remover 100 further includes a liquid leakage detection component 50, and the liquid leakage detection component 50 is configured to detect the liquid leakage state of the tank body 10.

[0114] In this embodiment, the liquid leakage detection component 50 can be a weighing sensor, which is used to detect the weight of the tank body 10 and its contents. When the measured weight is lower than the preset weight, it can be determined that there is a liquid leakage problem with the tank body 10. The liquid leakage detection component 50 can also be set as a liquid leakage detection belt. The liquid leakage detection belt includes a belt body and two induction wire cores arranged in the belt body. When the liquid contacts the liquid leakage detection belt, the liquid soaks into the interior through the small holes on the surface of the liquid leakage detection belt, causing the two induction wire cores to conduct, forming a loop resistance, and thus resulting in a change in current, so as to detect whether there is a liquid leakage problem.

[0115] By adopting the above method, the liquid leakage detection component 50 can be used to detect whether there is a liquid leakage problem with the tank body 10, so as to handle it in time when there is a liquid leakage, and avoid the leakage of battery slurry from affecting the operation of the equipment and polluting the environment.

[0116] Please refer to Figure 1 and Figure 2 , in some embodiments, a liquid leakage tray 60 is provided on the outer side of the tank body 10 for receiving the slurry overflowing from the tank body 10. The liquid leakage tray 60 is provided with a liquid discharge port 61; the liquid leakage detection component 50 includes a liquid receiving box 51 and a liquid leakage detection belt. The liquid receiving box 51 is arranged below the liquid discharge port 61, and the liquid leakage detection belt is arranged in the liquid receiving box 51.

[0117] In this embodiment, a liquid leakage tray 60 is arranged on the outer side of the tank body 10. When there is a liquid leakage problem with the tank body 10, the battery slurry overflowing from the tank body 10 first flows into the liquid leakage tray 60, and then flows into the liquid receiving box 51 of the liquid leakage detection tray through the liquid discharge port 61 of the liquid leakage tray 60. Optionally, the liquid discharge port 61 of the liquid leakage tray 60 can be arranged on the bottom wall of the tray, or a liquid discharge port 61 can be arranged on the side wall of the liquid leakage tray 60. In addition, the bottom wall of the liquid leakage tray 60 can be set to be inclined towards the liquid discharge port 61, so that the liquid in the liquid leakage tray 60 can flow to the liquid discharge port 61 in time and flow into the liquid receiving box 51 of the liquid leakage detection component 50.

[0118] For the specific structure of the liquid leakage detection belt, refer to the previous embodiment. When the liquid flows into the liquid receiving box 51, the liquid leakage detection belt can be triggered to enable the liquid leakage detection component 50 to send an induction signal; it can not only ensure that the liquid leakage detection component 50 can detect the liquid leakage problem in time when the tank body 10 leaks, but also, through the settings of the liquid leakage tray 60 and the liquid receiving box 51, avoid the overflowing battery slurry from flowing to areas outside the liquid leakage detection component 50, and avoid the leakage of battery slurry from affecting the operation of the equipment and polluting the environment.

[0119] Optionally, there are multiple tanks 10 in the iron remover 100. A liquid leakage tray 60 can be provided to receive the battery slurry leaked from the multiple tanks 10, or a liquid leakage tray 60 can be provided on the outside of each tank 10 respectively. Optionally, multiple liquid leakage detection components 50 can be provided, and each liquid leakage detection component 50 corresponds to one tank 10 and one liquid leakage tray 60 one by one. Or, as in the following embodiment, the same liquid leakage detection component 50 is used to detect the liquid leakage state of multiple tanks 10, which is not limited herein.

[0120] Please refer to Figure 1 and Figure 2 , in some embodiments, the iron remover 100 is provided with multiple tanks 10, and liquid leakage trays 60 are provided on the outside of each tank 10.

[0121] In this embodiment, the iron remover 100 is provided with multiple tanks 10 for containing battery slurry, and a set of magnetic bar assemblies 20 are correspondingly provided for each tank 10 to adsorb ferromagnetic materials. The iron remover 100 can clean a relatively large amount of battery slurry at one time, improving the cleaning efficiency.

[0122] Please refer to Figure 1 and Figure 2 , two adjacent liquid leakage trays 60 are arranged in a stepped manner, and the liquid leakage tray 60 at the lower position is arranged below the drain port 61 of the liquid leakage tray 60 at the higher position, and the liquid receiving box 51 is arranged below the drain port 61 of the liquid leakage tray 60 at the lower position. In this setting method, only a liquid leakage detection component 50 needs to be provided below the drain port 61 of the liquid leakage tray 60 at the lower position, and the liquid leakage tray 60 at the higher position can drain the liquid into the liquid leakage tray 60 below its drain port 61, and then flow to the liquid leakage detection component 50, so that the number of liquid leakage detection components 50 can be reduced and the structure can be simplified.

[0123] Please refer to Figure 1 and Figure 2 , in some embodiments, the drain ports 61 of two adjacent liquid leakage trays 60 are located above the same liquid receiving box 51. In this setting method, the liquid in two adjacent liquid leakage trays 60 is drained into the same liquid receiving box 51, so that the number of liquid leakage detection components 50 in the iron remover 100 can also be reduced and the structure can be simplified.

[0124] Optionally, there are three or more tanks 10 provided in the iron remover 100. Taking three tanks 10 as an example, the three liquid leakage trays 60 corresponding to the three tanks 10 can be arranged in a stepped manner, and the liquid receiving box 51 of the liquid leakage detection assembly 50 is arranged below the liquid receiving port of the liquid leakage tray 60 at the lowest position. Alternatively, two of the liquid leakage trays can be arranged in a stepped manner, and the drain port 61 of the liquid leakage tray 60 at the lower position is adjacent to the drain port 61 of another separately provided liquid leakage tray 60 and is above the same liquid receiving box 51. By adopting the above methods, the liquid in the three liquid leakage trays 60 can be drained into the same liquid receiving box 51, so as to reduce the number of liquid leakage detection devices in the iron remover 100 and simplify the structure.
