Description

Technical Field

[0001] This utility model relates to the technical field of electromagnetic iron removal devices, and more specifically, to a quick-release demagnetizing mechanism. Background Technology

[0002] In the new energy materials manufacturing industry, the requirements for magnetic materials are extremely strict. Electromagnetic separators are commonly used to demagnetize materials. An electromagnetic separator is a device that uses the principle of electromagnetic induction to remove ferromagnetic impurities from materials. Its working principle is based on the generation of a strong magnetic field by an energized coil, which uses magnetic force to attract ferromagnetic impurities and separate them from the material. The key component of an electromagnetic separator is the iron core, which is placed inside the cylinder during the iron removal process and removed from the cylinder when maintenance or replacement is required.

[0003] Existing technology discloses an electromagnetic iron removal device, which includes a cylinder, an upper cover plate, a lower cover plate, and an iron core. The upper and lower cover plates are detachably connected to both ends of the cylinder. A limiting member is provided on the downward-facing side of the upper cover plate, and a guide groove is provided on the upward-facing side of the lower cover plate. The upper end of the iron core has a limiting groove, and its lower end has a guide member. The iron core is located inside the cylinder, with the limiting groove aligned with the limiting member, and the guide groove aligned with the guide member. When the limiting groove and the limiting member are aligned, an anti-rotation fit is formed. Specifically, when placing the iron core, the lower cover plate and one end of the cylinder are connected first, the iron core is placed inside the cylinder, and then the upper cover plate is rotated to thread it onto the other end of the cylinder. When removing the iron core, the upper cover plate is rotated in the opposite direction to remove it, and then the iron core is taken out of the cylinder.

[0004] However, during the rotation of the top cover plate, if there is a slight deviation in the number of rotations of the thread or the starting position, the limiting component and the limiting groove may not be fully aligned, requiring repeated adjustments or even disassembly and reassembly. During the reverse rotation of the top cover plate, there is friction and jamming between the aligned limiting component and the limiting groove, which causes disassembly resistance, thus increasing the difficulty of disassembling and assembling the iron core. Utility Model Content

[0005] The purpose of this invention is to provide a quick-release demagnetizing mechanism, which solves the technical problem of how to reduce the difficulty of disassembling and assembling the iron core.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0007] This utility model provides a quick-release demagnetizing mechanism, comprising: an iron core, including a positioning rod and an iron core body connected together; a cylindrical body, which is hollow and tubular, having an inlet at the upper end and an outlet at the lower end; a hanging lug assembly, including two hanging lugs fixed to the inner wall of the cylindrical body, the two hanging lugs being centrally symmetrically distributed about the axis of the cylindrical body, and respectively allowing the two ends of the positioning rod to be inserted to hang the iron core body inside the cylindrical body; the hanging lugs have an opening on one side of the cylindrical body in the circumferential direction, the opening allowing the end of the positioning rod to enter or exit the hanging lug, and the openings of the two hanging lugs facing opposite directions; and a support base, fixed inside the cylindrical body and communicating with the inlet and outlet respectively, the support base being located below the hanging lug assembly and used to support the iron core body below.

[0008] In some embodiments of this application, the ear loop has a U-shaped structure and includes a first stop block, a second stop block, and a third stop block arranged sequentially from top to bottom. The first end of the first stop block and the first end of the second stop block are respectively connected to the third stop block. An opening is formed between the second end of the first stop block and the second end of the second stop block, and the opening is disposed opposite to the third stop block. The top of the second stop block is provided with an arc-shaped groove extending from the first end to the second end, and the arc-shaped groove is a concave structure with a lower middle and higher sides.

[0009] In some embodiments of this application, the cylinder includes an upper cylinder and a lower cylinder that are detachably connected. The lower end of the upper cylinder is connected to the upper end of the lower cylinder, and the upper end of the upper cylinder has the feed inlet, while the lower end of the lower cylinder has the discharge outlet. The hanging lug is fixed to the inner wall of the upper cylinder, and the support seat is fixed to the lower cylinder.

[0010] In some embodiments of this application, the upper cylinder includes a first main body and a first disc arranged around the outer periphery of the first main body, and the lower cylinder includes a second main body and a second disc arranged around the outer periphery of the second main body. The first disc has a first connecting hole extending through its upper and lower sides, and the second disc has a second connecting hole extending through its upper and lower sides. The cylinder also includes bolts, which are locked in the first connecting hole and the second connecting hole respectively to connect the first disc and the second disc, and the first main body and the second main body are in communication.

[0011] In some embodiments of this application, the upper cylinder includes an equal-diameter portion and a reduced-diameter portion arranged sequentially from top to bottom. The upper end of the equal-diameter portion has the feed port, the flared end of the reduced-diameter portion is connected to the lower end of the equal-diameter portion, and the reduced-diameter end is connected to the upper end of the lower cylinder.

[0012] In some embodiments of this application, the core body includes a core rod and iron chips. The core rod extends vertically and its upper end is connected to the positioning rod. There are several iron chips, and each iron chip is fixed to the core rod at intervals along the extension direction of the core rod. The iron chips are provided with gaps for material to pass through.

[0013] In some embodiments of this application, the support base is provided with a frustum-shaped positioning groove, and the lower end of the iron core rod is provided with a frustum-shaped positioning structure. The positioning structure is inserted into the positioning groove so that the support base is supported below the iron core body.

[0014] In some embodiments of this application, the support base includes a connecting base and a plurality of support rods arranged at intervals around the outer periphery of the connecting base. One end of each support rod is connected to the connecting base, and the other end is connected to the inner wall of the cylinder.

[0015] In some embodiments of this application, the quick-release demagnetizing mechanism further includes a motor bracket for fixing the vibration motor, the motor bracket being fitted around the cylinder body.

[0016] In some embodiments of this application, the upper end of the cylinder is provided with a first annular groove arranged coaxially with the feed port, and the outer wall of the cylinder is provided with a second annular groove arranged circumferentially along the cylinder, and the second annular groove is arranged near the lower end of the cylinder. Each of the annular grooves is used to place a sealing ring.

[0017] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0018] In this embodiment of the quick-release demagnetizing mechanism, the iron removal process is as follows: material enters the cylinder from the feed inlet, and as it flows through the iron core body, the iron core body magnetically attracts ferromagnetic impurities, while non-ferrous materials continue to fall and eventually flow out from the discharge outlet. Specifically, the hanging lug assembly and the positioning rod cooperate to suspend the iron core body inside the cylinder, and the support base provides bottom support for the iron core body. The three-point support structure formed by the two hanging lugs of the hanging lug assembly and the support base ensures that the iron core body is stably placed inside the cylinder, thereby ensuring that the iron removal work can be carried out stably.

[0019] Because the openings of the lugs are located circumferentially on the cylinder body, and the openings of the two lugs face opposite directions, the rotation of the positioning rod can cause both ends of the positioning rod to simultaneously retract or enter the two lugs. Specifically, when the iron core needs to be repaired or replaced, align both ends of the positioning rod with the openings of the two lugs respectively, apply a rotational force to the positioning rod to retract its end from the lug through the opening, and then pull the positioning rod, connected to the iron core body, out of the feed inlet to complete the removal of the iron core. Similarly, first place the entire iron core into the cylinder through the feed inlet, align both ends of the positioning rod with the openings of the two lugs respectively, and rotate them in opposite directions to enter the two lugs to complete the installation of the iron core. This allows for quick and convenient disassembly and installation of the iron core, reducing the difficulty of disassembly and installation. Attached Figure Description

[0032] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0033] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0034] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0035] Please see Figures 1 to 3 The quick-release demagnetizing mechanism provided in one embodiment of this utility model mainly includes an iron core 1, a cylindrical body 2, a lug assembly 3, and a support base 4. The iron core 1 includes a positioning rod 11 and an iron core body 12 connected together. The cylindrical body 2 is hollow and tubular, with an inlet 2113 at the upper end and an outlet 2211 at the lower end. The lug assembly 3 includes two lugs 31 fixed to the inner wall of the cylindrical body 2. The two lugs 31 are centrally symmetrically distributed about the axis of the cylindrical body 2 and are respectively inserted into the two ends of the positioning rod 11 to hang the iron core body 12 inside the cylindrical body 2. An opening 314 is provided on one side of the lug 31 in the circumferential direction of the cylindrical body 2. The opening 314 allows the end of the positioning rod 11 to enter or exit the lug 31, and the openings 314 of the two lugs 31 face opposite directions. The support base 4 is fixed inside the cylinder 2 and is connected to the feed port 2113 and the discharge port 2211 respectively. The support base 4 is located below the lug assembly 3 and is used to support the iron core body 12.

[0036] In the quick-release demagnetizing mechanism of this utility model embodiment, the iron removal process is as follows: the material enters the cylinder 2 from the feed inlet 2113, and when it flows through the iron core body 12, the iron core body 12 magnetically adsorbs ferromagnetic impurities, while the non-ferrous material continues to fall and finally flows out from the discharge outlet 2211. Specifically, the hanging ear assembly 3 and the positioning rod 11 cooperate to suspend the iron core body 12 inside the cylinder 2, and the support base 4 provides bottom support for the iron core body 12. The three-point support structure formed by the two hanging ears 31 of the hanging ear assembly 3 and the support base 4 can ensure that the iron core body 12 is stably placed inside the cylinder 2, so as to ensure that the iron removal work can be carried out stably.

[0037] Since the openings 314 of the lugs 31 are located circumferentially on the cylinder 2, and the openings 314 of the two lugs 31 face opposite directions, the rotation of the positioning rod 11 can cause both ends of the positioning rod 11 to simultaneously exit or enter the two lugs 31. Specifically, when the iron core 1 needs to be repaired or replaced, align both ends of the positioning rod 11 with the openings 314 of the two lugs 31 respectively, apply a rotational force to the positioning rod 11 to cause the end of the positioning rod 11 to exit from the opening 314 of the lug 31, and then pull the positioning rod 11 through the feed port 2113 to complete the removal of the iron core 1. Similarly, first place the entire iron core 1 into the cylinder 2 through the feed port 2113, align both ends of the positioning rod 11 with the openings 314 of the two lugs 31 respectively, and rotate it in opposite directions to enter the two lugs 31 to complete the installation of the iron core 1. Thus, the disassembly and installation of the iron core 1 can be completed quickly and conveniently, reducing the difficulty of disassembling and assembling the iron core 1.

[0038] It should be noted that in this embodiment, the lug 31 is fixed to the inner wall of the cylinder 2 by welding.

[0039] Please see Figure 3 In a specific embodiment, the lug 31 has a U-shaped structure and includes a first stop 311, a second stop 312, and a third stop 313 arranged sequentially from top to bottom. The first end of the first stop 311 and the first end of the second stop 312 are respectively connected to the third stop 313. An opening 314 is formed between the second end of the first stop 311 and the second end of the second stop 312, and the opening 314 is opposite to the third stop 313. The top of the second stop 312 is provided with an arc-shaped groove 3121 extending from the first end to the second end, and the arc-shaped groove 3121 has a concave structure that is low in the middle and high on both sides.

[0040] The first stop 311 and the third stop 313 respectively limit the upward and circumferential movement of the end of the positioning rod 11. The second stop 312 provides bottom support for the end of the positioning rod 11. The top of the second stop 312 has an arc-shaped groove 3121. On the one hand, after the end of the positioning rod 11 rotates into the lug 31, it can automatically align with the middle of the arc-shaped groove 3121 to complete quick positioning. On the other hand, the shape of the arc-shaped groove 3121, which is low in the middle and high on both sides, makes it less likely for the positioning rod 11 to accidentally come loose and exit from the lug 31 through the opening 314, thereby ensuring the stability of the overall structure.

[0041] It should be noted that during actual operation, after the end of the positioning rod 11 is aligned with the opening 314 and rotated into the lug 31, it will automatically sink into the middle of the arc-shaped groove 3121, and the bottom of the iron core body 12 will be supported on the support base 4. When removing the iron core 1, the entire iron core 1 needs to be lifted upwards so that the end of the positioning rod 11 is aligned with the opening 314, and then the end of the positioning rod 11 is rotated out of the lug 31.

[0042] Please see Figure 1 and Figure 2 In a specific embodiment, the cylinder 2 includes an upper cylinder 21 and a lower cylinder 22 that are detachably connected. The lower end of the upper cylinder 21 is connected to the upper end of the lower cylinder 22, and the upper end of the upper cylinder 21 has a feed inlet 2113. The lower end of the lower cylinder 22 has a discharge outlet 2211. The lug 31 is fixed to the inner wall of the upper cylinder 21, and the support base 4 is fixed inside the lower cylinder 22.

[0043] In actual use, if the iron impurities entering the iron removal machine are too large or too numerous, the iron core 1 may get stuck and be difficult to remove normally. Since the upper cylinder 21 and the lower cylinder 22 are connected in a detachable manner, the connection between the upper cylinder 21 and the lower cylinder 22 can be disconnected first, and the upper cylinder 21 and the iron core 1 can be removed as a whole. Then, the positioning rod 11 can be removed from the lug 31, thereby further reducing the difficulty of disassembling and assembling the iron core 1.

[0044] In a specific embodiment, the upper cylinder 21 includes a first main body 211 and a first disc 212 arranged around the outer periphery of the first main body 211. The lower cylinder 22 includes a second main body 221 and a second disc 222 arranged around the outer periphery of the second main body 221. The first disc 212 has a plurality of first connecting holes 2121 penetrating its upper and lower sides, and the second disc 222 has a plurality of second connecting holes 2221 penetrating its upper and lower sides. The cylinder 2 also includes bolts (bolts not shown in the figures), which are locked in the first connecting holes 2121 and the second connecting holes 2221 respectively to connect the first disc 212 and the second disc 222, and to connect the lower end of the first main body 211 with the upper end of the second main body 221.

[0045] The first main body 211 and the second main body 221 are respectively used to undertake the main functions of the upper cylinder 21 and the lower cylinder 22. The first disc 212 and the second disc 222 are respectively used to undertake the connection function of the upper cylinder 21 and the lower cylinder 22. Through the cooperation between the first connecting hole 2121 of the first disc 212, the second connecting hole 2221 of the second disc 222 and the bolt, the upper cylinder 21 and the lower cylinder 22 can be detachably connected, which has the advantages of stable and reliable connection and easy disassembly and assembly.

[0046] It is conceivable that there are at least two bolts, arranged at equal intervals. For example, when there are two bolts, the angle between the two bolts is 180 degrees; when there are three bolts, the angle between the three bolts is 120 degrees, and so on.

[0047] In this embodiment, the lower end of the first disc 212 is slightly higher than or flush with the lower end of the first main body 211, and the upper end of the second disc 222 is slightly lower than or flush with the upper end of the lower cylinder 22. When the first disc 212 and the second disc 222 are connected, a sealing ring is sandwiched between the first disc 212 and the second disc 222, thereby improving the sealing performance at the connection between the upper cylinder 21 and the lower cylinder 22 and preventing material leakage.

[0048] In a further embodiment, a spring retaining ring is provided at the lower end of the second disc 222.

[0049] Please see Figures 1 to 3 In a specific embodiment, the upper cylinder 21 includes an equal diameter portion 2111 and a reduced diameter portion 2112 arranged sequentially from top to bottom. The upper end of the equal diameter portion 2111 has a feed inlet 2113. The flared end of the reduced diameter portion 2112 is connected to the lower end of the equal diameter portion 2111, and the reduced diameter end of the reduced diameter portion 2112 is connected to the upper end of the lower cylinder 22.

[0050] The equal diameter section 2111 has a large diameter, which facilitates the feeding of materials. The narrow diameter section 2112 forms a gradually narrowing flow channel, which can accelerate the material passing speed. The equal diameter section 2111, the narrow diameter section 2112 and the lower cylinder 22 are arranged in sequence and work together to accelerate the iron removal efficiency of materials.

[0051] Please see Figure 2 and Figure 4In a specific embodiment, the iron core body 12 includes an iron core rod 121 and iron chips 122. The iron core rod 121 extends vertically, and its top end is connected to the positioning rod 11. There are several iron chips 122, each fixed to the iron core rod 121 at intervals along its extension direction. The iron chips 122 have gaps for material to pass through. This provides a practical and feasible structure for the iron core body 12, and the multi-layered arrangement of iron chips 122 along the iron core rod 121 covers a larger magnetic field area, improving the adsorption capacity of fine iron filings.

[0052] In a specific embodiment, the support base 4 has a frustum-shaped positioning groove 411, and the lower end of the iron core rod 121 has a frustum-shaped positioning structure 1211. The positioning structure 1211 is inserted into the positioning groove 411 so that the support base 4 is supported below the iron core body 12. The positioning groove 411 and the positioning structure 1211 cooperate through their frustum-shaped shapes, which can realize the automatic alignment of the iron core rod 121 and the iron core piece 122 on it, and can effectively limit the movement of the iron core body 12 on the support base 4, thereby further improving the stability of the overall structure.

[0053] Please see Figure 5 In a specific embodiment, the support base 4 includes a connecting base 41 and a plurality of support rods 42 arranged at intervals around the outer periphery of the connecting base 41. One end of the support rod 42 is connected to the connecting base 41, and the other end is connected to the inner wall of the cylinder 2. Its structure is stable, and the interval between two adjacent support rods 42 allows non-ferrous materials to pass through and eventually flow out from the discharge port 2211.

[0054] In this embodiment, a positioning groove 411 is provided on the connecting seat 41. The weight of the iron core body 12 is applied to the connecting seat 41 and distributed and transmitted to the inner wall of the cylinder 2 through multiple support rods 42, thereby improving its support for the iron core body 12 and enhancing the stability of the overall structure.

[0055] It should be noted that in this embodiment, the support rod 42 is connected to the connecting seat 41 and the inner wall of the cylinder 2 by welding.

[0056] In this embodiment, the support rods 42 extend radially along the cylinder 2, and there are four of them, which are evenly distributed.

[0057] Please see Figures 1 to 3 In a specific embodiment, the quick-release demagnetizing mechanism also includes a motor bracket 5 for fixing the vibrating motor, which is attached to the outside of the cylinder 2. The motor bracket 5 being attached to the outside of the cylinder 2 allows the high-frequency vibration of the vibrating motor to be directly transmitted to the entire cylinder 2, thereby accelerating the iron removal process of the material, reducing material blockage within the cylinder 2, and thus improving iron removal efficiency.

[0058] Please see Figure 1 , Figure 3 and Figure 5 In a specific embodiment, the upper end of the cylinder 2 is provided with a first annular groove 2114 arranged coaxially with the feed port 2113, and the outer wall of the cylinder 2 is provided with a second annular groove 2212 arranged along the circumference of the cylinder 2, and the second annular groove 2212 is arranged close to the lower end of the cylinder 2. Each annular groove is used to place a sealing ring.

[0059] The first annular groove 2114 and the second annular groove 2212 are provided to ensure the sealing of the quick-release demagnetizing mechanism when connected to other structures in the electromagnetic separator, and to ensure that the material can flow in and out correctly. On the other hand, since the cylinder 2 and its related components vibrate as a whole under the action of the vibrating motor, if the quick-release demagnetizing mechanism is rigidly connected to other mechanisms, the effect of vibration feeding will be greatly limited.

[0060] It should be noted that in the above embodiments, the iron core 1 has magnetic force when excited by an external current. In other embodiments, the iron core 1 can be replaced with other materials with permanent magnetism.

[0061] It should be noted that the quick-release demagnetizing mechanism in the above embodiments is mainly used in scenarios where ferromagnetic impurities are separated from lithium battery cathode materials.

[0062] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
