Description

Technical Field

[0001] This utility model relates to the field of lithium battery magnetic separation and recycling technology, and in particular to a lithium battery recycling magnetic separation processing device. Background Technology

[0002] Magnetic separation recycling of lithium batteries refers to the process of separating and recycling valuable metal materials from waste lithium batteries using magnetic materials. This technology helps reduce resource waste and environmental pollution, and improves the reuse rate of waste lithium batteries.

[0003] Patent document CN222035162U discloses a magnetic separation recycling device for lithium batteries, including a base plate, a turntable rotatably connected to the top of the base plate, a transmission assembly on the top of the base plate for driving the turntable to rotate, a magnetic separation drum fixedly connected to the top of the turntable, a magnetic separation cover above the magnetic separation drum, a first vertical plate and a second vertical plate fixedly connected to the top of the base plate, a lifting assembly inside the first vertical plate for moving the magnetic separation cover, and a feeding port fixedly connected to the top of the magnetic separation cover. This invention uses the magnetic separation assembly to perform magnetic separation on the material introduced into the magnetic separation drum. A rotating rod drives the magnetic column to rotate, thoroughly dispersing the material. Simultaneously, magnetically conductive materials are adsorbed onto the magnetic column. After magnetic separation, the lifting assembly removes the magnetic column from the magnetic separation drum, further facilitating the rapid separation of magnetically conductive and non-magnetically conductive materials, thereby enabling rapid magnetic separation recycling of lithium batteries.

[0004] When using the above-mentioned technology, the following technical problems were found in the existing technology: Although lifting the magnetic column away from the magnetic separation tank by the lifting component can remove the magnetically separated magnetic material from the magnetic column, the detached magnetic material will immediately fall back into the magnetic separation tank, making it difficult to collect the magnetic material; in addition, because the crushing step before magnetic separation in lithium battery recycling is not precise enough, the materials to be magnetically separated are of different sizes. After magnetic separation, it is necessary to filter out magnetic and non-magnetic materials of different sizes to facilitate recycling by size. To address these issues, a lithium battery recycling magnetic separation processing device is designed to provide an alternative technical solution. Summary of the Invention

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

[0007] A magnetic separation processing device for lithium battery recycling includes a frame and further includes:

[0017] The first and second channels have opposite discharge directions and are both connected to the receiving hopper. The filter body is used to filter out materials of different sizes and is placed in the first and second channels respectively.

[0018] In a preferred embodiment of the lithium battery recycling magnetic separation device provided by this utility model, the filter body includes two filter plates corresponding to the first channel and the second channel respectively, wherein the filter holes on one of the filter plates are larger or smaller than the filter holes on the other filter plate.

[0019] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0020] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] like Figure 1 - Figure 3 As shown, this lithium battery recycling magnetic separation treatment device includes a frame 1, a feeding hopper 2, a discharging component 3, a magnetic separation chamber 4, and a magnetic control mechanism 5. The magnetic separation chamber 4 is rotatably mounted on the frame 1 and is used to receive waste materials formed after the lithium battery is crushed through the feeding hopper 2. The waste materials include both magnetic and non-magnetic materials. The magnetic and non-magnetic materials located in the magnetic separation chamber 4 are separated by magnetic separation using the magnetic control mechanism 5 located in the magnetic separation chamber 4. Specifically, the magnetic materials in the waste materials are separated by magnetic attraction through the expansion of magnetic force. Finally, the magnetic and non-magnetic materials are discharged from the magnetic separation chamber 4 by the discharging component 3.

[0035] like Figure 2 and Figure 3 As shown, and refer to Figure 1A set of plates 11 is provided in the transverse direction of the frame 1. The magnetic separation chamber 4 is rotatably connected between the set of plates 11. A reduction motor 6 is fixed on one of the plates 11 and coaxially connected to the magnetic separation chamber 4. The reduction motor 6 drives the magnetic separation chamber 4 to rotate on the frame 1.

[0036] Furthermore, the feed hopper 2 is fixed to one side of the top of the frame 1, and the discharge component 3 is fixed to the inner bottom of the frame 1; the magnetic separation chamber 4 is provided with a feed port 41, which is used to rotate the corresponding feed hopper 2 or discharge component 3 under the drive of the reduction motor 6. In this way, the reduction motor 6 is used to switch the feed port 41 to the corresponding feed hopper 2 or discharge component 3 by a rotation of much less than one revolution. When the feed port 41 is in the corresponding feed hopper 2, the waste material formed after the lithium battery is crushed can be discharged into the magnetic separation chamber through the feed hopper 2 and the feed port 41. Inside the magnetic separation chamber 4, and concentrated in the middle area at the bottom of the magnetic separation chamber 4, when the magnetic materials are attracted by the magnetic control mechanism 5, the material outlet 41 is rotated to correspond to the discharge component 3. (Under the action of gravity, the non-magnetic materials remain in the middle area at the bottom of the magnetic separation chamber 4) The non-magnetic materials are discharged through the material outlet 41 and the discharge component 3. Finally, the magnetic control mechanism 5 reduces the magnetism, allowing the magnetic materials to detach from the magnetic control mechanism 5 and be discharged through the discharge component 3, thereby achieving the magnetic separation and recovery of the magnetic materials.

[0037] The discharge component 3 has a first channel 31 and a second channel 32. The first channel 31 and the second channel 32 are used to discharge materials of different sizes. Specifically, the first channel 31 discharges larger magnetic and non-magnetic materials, while the second channel 32 discharges smaller magnetic and non-magnetic materials.

[0038] like Figure 4 As shown, and refer to Figure 2 The magnetic control mechanism 5 includes a first magnet 51, a second magnet 52, a braking element that controls the second magnet 52 to overlap or move away from the first magnet 51, and a housing 53 that carries the first magnet 51, the second magnet 52, and the braking element. Specifically, the second magnet 52 is rotatably connected inside the housing 53, so that the second magnet 52 can be driven to rotate by the braking element to overlap with the first magnet 51, and a magnetic force that can attract magnetic materials is generated when they overlap. Conversely, when the braking element drives the second magnet 52 to rotate and detach from the first magnet 51, the first magnet 51 cannot attract the magnetic materials in the magnetic separation chamber 4. Therefore, in this example, the first magnet 51 is limited to having a magnetic force that cannot attract the magnetic materials in the magnetic separation chamber 4 individually (specifically, the appropriate magnetic force is obtained by controlling the body shape), and the entry of each batch of materials into the magnetic separation chamber 4 is limited by a controlled amount. Therefore, the magnetic materials in a batch cannot be attracted by the first magnet 51 alone.

[0039] Furthermore, a wire groove 42 is provided on the magnetic separation chamber 4. The wire groove 42 is used to accommodate the wiring or liquid circuit connected to the braking component of the magnetic control mechanism 5, so that the braking component inside the magnetic separation chamber 4 can still receive external control signals.

[0040] The braking component further includes: a set of brackets 55 fixedly connected to the second magnet 52, a shaft 56 fixed between the set of brackets 55, and at least one hydraulic cylinder 57 respectively hinged between the shaft 56 and the housing 53. The hydraulic oil circuit connected to the hydraulic station passes through the wire groove 42 and is connected to the hydraulic cylinder 57. Under the control of the hydraulic station, the hydraulic oil enters or exits the hydraulic cylinder 57 through the oil circuit, thereby driving the piston shaft of the hydraulic cylinder 57 to extend and retract. This drives the second magnet 52 to rotate and match with the first magnet 51 through the shaft 56 and the set of brackets 55. When they match, the magnetic force is significantly increased and it can magnetically attract magnetic materials in a batch. When the magnetic force is reduced, the second magnet 52 is driven to rotate away from the feed port 41 of the magnetic separation chamber 4. At this time, the magnetic materials magnetically attracted to the outer surface of the middle part of the bottom of the housing 53 will fall downward.

[0041] In some embodiments, the first magnet 51 and the second magnet 52 are both electromagnets, and the braking component is a relay module that controls the circuit of the first magnet 51 and the second magnet 52. In this embodiment, the first magnet 51 and the second magnet 52 are both fixed at different positions within the housing 53. Referring to the previous figure, the relay module controls the first magnet 51 and / or the second magnet 52 to be energized or de-energized to generate a larger magnetic force, or to reduce the magnetic force based on the larger magnetic force, so that the magnetic material is magnetically attracted to the outside of the housing 53, or falls off the outside of the housing 53.

[0042] It should be noted that the housing 53 is indirectly fixedly connected to a set of plates 11 on the frame 1 without affecting the rotation of the magnetic separation chamber 4, thereby restricting the housing 53 to be fixedly located inside the magnetic separation chamber 4. Specifically, a set of support columns 54 are fixed at the middle of both ends of the housing 53. The two sets of support columns 54 pass through the sliding grooves opened in the middle area on both sides of the magnetic separation chamber 4 and are fixedly connected to a set of plates 11 on the frame 1. With the cooperation of the support columns 54 and the sliding grooves, the magnetic separation chamber 4 can switch its own material inlet 41 to the rotation of the feed hopper 2 or the discharge component 3 without being restricted by the support columns 54.

[0043] like Figure 5 As shown, and refer to Figure 1 and Figure 3 The discharge component 3 also includes a receiving hopper 33 and a filter body disposed in the receiving hopper 33. Based on this, the discharge directions of the first channel 31 and the second channel 32 are opposite and both are connected to the receiving hopper 33. The filter body is used to filter out materials of different sizes and is placed in the first channel 31 and the second channel 32 respectively, so that magnetic and non-magnetic materials of different sizes are discharged through the first channel 31 and the second channel 32.

[0044] Furthermore, the opening of the receiving hopper 33 is preferably larger than or matched with the length and width of the magnetic separation chamber 4, so as to ensure that when the material outlet 41 rotates downward with the magnetic separation chamber 4 as the axis, the material leaking out through the material outlet 41 completely enters the receiving hopper 33.

[0045] The filter body includes two filter plates 34 corresponding to the first channel 31 and the second channel 32 respectively. The filter holes on one filter plate 34 are larger or smaller than the filter holes on the other filter plate 34. Materials of different sizes are filtered out by the size of the filter holes on the filter plates 34 and discharged through the first channel 31 and the second channel 32 respectively.

[0046] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
