Description

Technical Field

[0001] This utility model belongs to the field of waste lithium battery recycling technology, specifically relating to a hydrodynamic-eddy current copper-aluminum foil high-efficiency sorting system device. Background Technology

[0002] With the popularization of new energy vehicles in my country and the upgrading of automotive power batteries, the number of retired power batteries is increasing year by year. The harmless treatment of retired lithium batteries is a social problem that urgently needs to be solved; at the same time, the precious and rare metals in the batteries, such as lithium, cobalt, and nickel, as well as the positive and negative electrode metal materials copper and aluminum, also have high recycling value.

[0003] Existing technologies for sorting and recycling waste lithium batteries typically involve mechanical-physical separation. However, some physical separation methods suffer from low efficiency, high impurity levels, significant safety hazards, difficulty in separating copper and aluminum, and environmental pollution. Both copper and aluminum have good ductility, and the foils easily entangle, leading to a significant reduction in mechanical sorting efficiency and an increase in impurities. Furthermore, material splashing during mechanical screening poses a considerable safety hazard.

[0004] Patent CN109261517A discloses a method and system for separating copper and aluminum from waste lithium batteries. This method involves crushing waste lithium batteries, followed by vibratory screening and magnetic separation. A second screening process yields a mixture of metals and non-metals, which is then separated by air separation to remove the non-metallic material. Finally, the air-separated aluminum-copper mixture is separated by heating. However, this technical solution involves two mechanical screening processes, which can easily cause dust pollution and pose safety hazards to the operating environment. Furthermore, because the fan's airflow is fixed, the air separation device has certain limitations. If the size of the incoming material does not meet the fan's settings, the separation accuracy of the air separation will be affected, resulting in a poorer separation effect.

[0005] Patent CN111974785A discloses a method for the pyrolysis recycling of waste lithium batteries. First, the primary raw materials after discharge and crushing are pyrolyzed to remove water, electrolyte, binder, and separator, yielding the pyrolysis raw material. Then, the pyrolysis material is sorted by wet screening to obtain electrode powder and a copper-aluminum sheet mixture. Next, flotation is used to obtain the positive electrode active material and graphite powder, respectively. Finally, a metal separator is used to separate the copper-aluminum sheet mixture into copper and aluminum components. This technical solution suffers from drawbacks such as complex operation and high energy consumption.

[0006] Because copper and aluminum foils have good ductility, they are prone to entanglement, resulting in low mechanical sorting efficiency (recovery rate <90%). To efficiently sort and recover valuable components such as positive and negative electrode powders, copper, and aluminum, and maximize recycling, it is still necessary to develop a sorting system that can achieve efficient, safe, and environmentally friendly sorting of copper and aluminum foils. This has significant guiding significance for production practice. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention provides a hydrodynamic-eddy current copper-aluminum foil high-efficiency sorting system, comprising a hydrodynamic sorting unit and an eddy current sorting unit connected in sequence. The key feature is an adjustable baffle linked to a laser feedback unit installed at the outlet of the eddy current separator in the eddy current sorting unit. Based on real-time monitoring of the aluminum foil offset distance by the laser feedback unit, the adjustable baffle can control the size of the aluminum foil collection port. This not only enables the separation of electrode powder from copper and aluminum foil in waste lithium batteries but also achieves efficient separation between copper and aluminum foil, realizing the secondary utilization of copper and aluminum resources.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] This utility model provides a hydrodynamic-eddy current copper-aluminum foil high-efficiency sorting system device, including a hydrodynamic sorting unit and an eddy current sorting unit connected in sequence; the upper outlet of the hydrodynamic sorting unit is connected to an electrode powder recovery unit, and the lower outlet of the hydrodynamic sorting unit is connected to the inlet of the eddy current sorting unit.

[0010] The eddy current separation unit includes an eddy current separator. An adjustable baffle that is linked to a laser feedback unit is installed at the outlet of the eddy current separator. The laser feedback unit is used to monitor the aluminum foil offset distance in real time, and the adjustable baffle is used to adjust the size of the aluminum foil collection port.

[0011] The hydrodynamic-eddy current copper-aluminum foil high-efficiency separation system of this invention is a system device for the efficient separation of copper and aluminum foil from waste lithium batteries. This system first uses hydraulic stripping to remove electrode powder from the crushed raw material, and then employs an eddy current separation unit to deflect the aluminum foil under eddy current force, achieving copper-aluminum foil separation. The interconnected laser feedback unit and adjustable baffle allow for control of the aluminum foil collection port size, improving the separation efficiency of copper and aluminum foil. This system is a two-stage separation system of hydraulic stripping and eddy current separation. It first efficiently recovers positive and negative electrode powder through hydraulic stripping, and then efficiently controls the separation of aluminum and copper foil through eddy current separation, achieving efficient separation of electrode powder, aluminum foil, and copper foil from waste lithium batteries and enabling the secondary utilization of aluminum and copper resources.

[0012] As a preferred technical solution of this utility model, the eddy current separator is a magnetic roller type eddy current separator, and the adjustable baffle is set at the junction between the copper foil collector and the aluminum foil collector.

[0013] It should be noted that if the eddy current separator is a magnetic roller type eddy current separator, when the mixture to be separated passes above the rotating magnetic roller, both copper foil and aluminum foil, which are conductive materials, will be ejected due to repulsive force. However, the aluminum foil is ejected a farther distance, so the aluminum foil collector at the discharge port is placed at a farther distance, while the copper foil is ejected a shorter distance, so the copper foil collector at the discharge port is placed at a closer distance. That is, the copper foil collector and the aluminum foil collector are set one near and one far. The adjustable baffle is set at the junction between the copper foil collector and the aluminum foil collector. The size of the aluminum foil collection port is adjusted by the tilt angle in the near and far directions.

[0014] As a preferred technical solution of this utility model, the eddy current separator is an inclined plate type eddy current separator, which includes an inclined magnetic plate and an adjustable baffle is disposed at the outlet end of the inclined magnetic plate; wherein, the magnetic field of the inclined magnetic plate includes a magnetic field formed by alternating N-pole magnets and S-pole magnets or an electromagnetic field based on current.

[0015] It should be noted that the magnetic field direction of the fixed magnetic field in which several N-pole magnets and S-pole magnets are alternately set is the direction in which the N-pole magnets and S-pole magnets extend alternately.

[0016] As a preferred technical solution of this utility model, the angle between the magnetic field direction of the inclined magnetic plate and the inclined downward direction is 20-40 degrees, such as 20 degrees, 21 degrees, 23 degrees, 25 degrees, 26 degrees, 28 degrees, 30 degrees, 32 degrees, 35 degrees, 37 degrees, 38 degrees or 40 degrees.

[0017] As a preferred technical solution of this utility model, the adjustable baffle is set at a distance of 10-15cm, perpendicular to the inclined downward direction of the inclined magnetic plate, such as 10cm, 11cm, 12cm, 13cm, 14cm or 15cm.

[0018] It should be noted that if the eddy current separator is an inclined plate type eddy current separator, the inclined magnetic plate is tilted downwards along the material flow direction. Due to the angle between the magnetic field direction of the inclined magnetic plate and the downward tilting direction, the aluminum foil will be laterally offset because the repulsive force it experiences is greater than the frictional resistance. Although the copper foil will also be laterally offset due to the repulsive force, the lateral offset distance is smaller, causing the copper foil to fall almost vertically along the downward tilting direction. Further experimental research has shown that setting the angle between the magnetic field direction of the inclined magnetic plate and the downward tilting direction to 20-40 degrees can make the lateral offset distance of the aluminum foil >10cm, generally 10-15cm. An adjustable baffle is set at the offset distance of 10-15cm to achieve effective separation of copper foil and aluminum foil. In addition, if the magnetic field of the tilted magnetic plate is an electromagnetic field based on current, such as an electromagnetic field generated by a pulse magnetic field generator, the aluminum foil can be deflected by eddy current force by controlling the direction of the magnetic field, thus achieving the separation of copper and aluminum foil. Alternatively, the magnetic field strength can be adjusted to maintain the deflection of the aluminum foil within the target range, such as a lateral deflection distance of >10cm, typically 10-15cm.

[0019] As a preferred technical solution of this utility model, the adjustable baffle adjusts the size of the aluminum foil collection port by sliding parallel to the guide rail.

[0020] As a preferred technical solution of this utility model, the adjustable baffle adjusts the size of the aluminum foil collection port by deflection angle.

[0021] It should be noted that if the eddy current separator is an inclined plate type eddy current separator, the copper foil will fall almost vertically along the inclined downward direction, while the aluminum foil will be significantly deflected laterally. Based on the aluminum foil deflection distance monitored in real time by the laser feedback unit, the adjustable baffle can be adjusted by sliding parallel to the guide rail or by deflecting the angle to adjust the size of the aluminum foil collection port.

[0022] As a preferred technical solution of this utility model, anti-splash baffles are provided on both sides of the inclined magnetic plate.

[0023] As a preferred technical solution of this utility model, a centrifuge is provided between the lower outlet of the hydrodynamic separation unit and the inlet of the eddy current separation unit. The solid phase outlet of the centrifuge is connected to the inlet of the eddy current separation unit, and the liquid phase outlet of the centrifuge is connected to the electrode powder recovery unit.

[0024] It should be noted that the electrode powder separated by the hydrodynamic separation unit will enter the electrode powder recovery unit along with the liquid phase. The addition of a centrifuge is to further recover the electrode powder slurry attached to the mixture after hydrodynamic separation and enter it into the electrode powder recovery unit, thereby helping to achieve efficient separation of electrode powder, aluminum foil and copper foil in waste lithium batteries.

[0025] As a preferred technical solution of this utility model, the hydrodynamic sorting unit includes a hydrocyclone, and the cone angle of the cyclone cavity of the hydrocyclone is 35-45 degrees, such as 35 degrees, 36 degrees, 37 degrees, 38 degrees, 39 degrees, 40 degrees, 41 degrees, 42 degrees, 43 degrees, 44 degrees or 45 degrees, preferably 38-42 degrees.

[0026] As a preferred technical solution of this utility model, the inlet pressure of the hydrocyclone is 0.45-0.55MPa, such as 0.45MPa, 0.46MPa, 0.47MPa, 0.48MPa, 0.49MPa, 0.50MPa, 0.51MPa, 0.52MPa, 0.53MPa, 0.54MPa or 0.55MPa, etc.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] This invention provides a hydrodynamic-eddy current copper-aluminum foil high-efficiency sorting system, comprising a hydrodynamic sorting unit and an eddy current sorting unit connected in sequence. The key feature is an adjustable baffle linked to a laser feedback unit installed at the outlet of the eddy current separator in the eddy current sorting unit. Based on real-time monitoring of the aluminum foil offset distance by the laser feedback unit, the adjustable baffle can control the size of the aluminum foil collection port. This not only achieves the separation of electrode powder from copper and aluminum foil in waste lithium batteries, but also enables efficient separation between copper and aluminum foil, achieving the secondary utilization of copper and aluminum resources.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] One specific embodiment of this utility model provides a hydrodynamic-eddy current copper-aluminum foil high-efficiency sorting system device, including a hydrodynamic sorting unit and an eddy current sorting unit connected in sequence; the upper outlet of the hydrodynamic sorting unit is connected to an electrode powder recovery unit, and the lower outlet of the hydrodynamic sorting unit is connected to the inlet of the eddy current sorting unit; wherein, the eddy current sorting unit includes an eddy current separator, and an adjustable baffle linked to a laser feedback unit is provided at the outlet of the eddy current separator. The laser feedback unit is used to monitor the aluminum foil offset distance in real time, and the adjustable baffle is used to adjust the size of the aluminum foil collection port.

[0033] Preferably, the eddy current separator is an inclined plate type eddy current separator, which includes an inclined magnetic plate and an adjustable baffle is disposed at the outlet end of the inclined magnetic plate; wherein, the magnetic field of the inclined magnetic plate is an electromagnetic field based on current generation.

[0034] Preferably, the angle between the magnetic field direction of the inclined magnetic plate and the inclined downward direction is 20-40 degrees.

[0035] Preferably, the adjustable baffle is set at a distance of 10-15cm from the inclined downward direction of the inclined magnetic plate.

[0036] Preferably, the adjustable baffle adjusts the size of the aluminum foil collection port by sliding parallel to the guide rail.

[0037] Preferably, anti-splash baffles are provided on both sides of the inclined magnetic plate.

[0038] Preferably, a centrifuge is installed between the lower outlet of the hydrodynamic separation unit and the inlet of the eddy current separation unit. The solid phase outlet of the centrifuge is connected to the inlet of the eddy current separation unit, and the liquid phase outlet of the centrifuge is connected to the electrode powder recovery unit.

[0039] Preferably, the hydrodynamic sorting unit includes a hydrocyclone, wherein the cone angle of the cyclone cavity of the hydrocyclone is 35-45 degrees.

[0040] The above-described high-efficiency hydrodynamic-eddy current copper-aluminum foil separation method includes the following steps: Crushed material is added to a hydrocyclone for hydrodynamic separation, where the electrode powder is stripped away; the mixture after hydrodynamic stripping is then subjected to eddy current separation to separate the copper and aluminum foils; the hydrocyclone's cyclone chamber cone angle is 40±2 degrees, and the inlet pressure is maintained at 0.5±0.05MPa. The electrode powder in the crushed material is stripped away by hydraulic force, and a cone valve at the bottom of the cyclone chamber discharges the electrode powder at regular intervals as the outlet; the mixture after hydrodynamic stripping is then subjected to eddy current separation. A pulsed magnetic field generator (e.g., a periodic change in current with a sinusoidal waveform distribution, a magnetic field strength of 20-25T, and a time gradient >4000T / s) is deflected at a 30-degree angle to the vertical magnetic field direction. The aluminum foil in the mixture after hydrodynamic stripping is laterally deflected by the eddy current force, with a deflection distance >10cm, while the copper foil falls almost vertically, at which point the copper and aluminum foils separate. Copper foil outlet: The copper foil falls almost vertically. Aluminum foil outlet: An adjustable baffle is installed 10-15cm to the side. The parallel sliding distance of the baffle is controlled by a motor and is linked to laser feedback.

[0041] In practical operation, during the hydrodynamic stripping of the electrode powder, the cone angle of the swirling cavity must be controlled at 40±2 degrees, and the inlet pressure maintained at 0.5±0.05MPa. Properly controlling the angle of the swirling cavity and the inlet pressure is crucial for efficient stripping. The key to eddy current separation is that the aluminum foil is laterally deflected by the eddy current force, effectively separating the copper foil from the aluminum foil, allowing the copper foil to fall. In the eddy current system, the laser rangefinder of the laser feedback unit monitors the aluminum foil's deflection distance in real time and adjusts the magnetic field strength to maintain the deflection at 10-15cm. An adjustable baffle is set at a lateral position of 10-15cm as the aluminum foil outlet. The parallel sliding distance of the adjustable baffle is controllable and linked with the laser rangefinder to ensure effective aluminum foil collection.

[0042] Example 1

[0043] This embodiment provides a hydrodynamic-eddy current copper-aluminum foil high-efficiency sorting system, including a hydrodynamic sorting unit and an eddy current sorting unit connected in sequence. The upper outlet of the hydrodynamic sorting unit is connected to an electrode powder recovery unit, and the lower outlet of the hydrodynamic sorting unit is connected to the inlet of the eddy current sorting unit. The eddy current sorting unit includes an eddy current separator, and an adjustable baffle linked to a laser feedback unit is installed at the outlet of the eddy current separator. The laser feedback unit is used to monitor the aluminum foil offset distance in real time, and the adjustable baffle is used to adjust the size of the aluminum foil collection port. The eddy current separator is an inclined plate type eddy current separator. The inclined plate type eddy current separator includes an inclined magnetic plate, and an adjustable baffle is disposed at the outlet end of the inclined magnetic plate. The magnetic field of the inclined magnetic plate is an electromagnetic field generated by a periodically changing current with a sinusoidal waveform distribution. The angle between the magnetic field direction of the inclined magnetic plate and the inclined downward sliding direction is 30 degrees. The adjustable baffle is disposed perpendicular to the inclined downward sliding direction of the inclined magnetic plate at a distance of 10-15 cm. The adjustable baffle adjusts the size of the aluminum foil collection port by sliding parallel to the guide rail. Anti-splash baffles are disposed on both sides of the inclined magnetic plate. The hydrodynamic separation unit includes a hydrocyclone, and the cone angle of the cyclone cavity of the hydrocyclone is 40 degrees.

[0044] Figure 1 The diagram shows a schematic of the inclined plate eddy current separator in Embodiment 1. The top of the inclined magnetic plate 3 is used to receive the material 1 transported by the conveyor belt 2. After the material 1 falls into the inclined magnetic plate 3, the aluminum foil 5 therein will be laterally offset due to the repulsive force. Figure 1The blue arrow in the middle indicates the direction of the lateral offset. The copper foil 4 will also be offset by the repulsive force, but the aluminum foil is subjected to a stronger repulsive force and offsets a greater distance. The copper foil falls almost vertically along the inclined downward direction. The laser feedback unit 7 is set at the upstream end near the adjustable baffle 6. By monitoring the lateral offset distance of the aluminum foil that is about to approach the adjustable baffle 6 in real time, the position of the adjustable baffle 6, which slides parallel to the guide rail, is adjusted by the motor, thereby controlling the size of the aluminum foil collection port.

[0045] Application Example 1

[0046] This application example uses the hydrodynamic-eddy current copper-aluminum foil high-efficiency sorting system device described in Example 1. The high-efficiency sorting method includes:

[0047] 100 kg of crushed material was added to a hydrocyclone for hydrodynamic separation. The cone angle of the cyclone chamber was controlled at 40 ± 2 degrees, and the inlet pressure was maintained at 0.5 ± 0.05 MPa. This yielded 93.2 kg of electrode powder and 6.8 kg of hydrodynamically screened mixture, with an electrode powder shedding rate of 98.1%. Eddy current separation was then applied to the hydrodynamically screened mixture, maintaining a magnetic field strength of 20-25 T, a time gradient > 4000 T / s, and a deflection channel at a 30-degree angle to the perpendicular magnetic field direction. This resulted in 2.9 kg of copper foil and 3.9 kg of aluminum foil, with a copper recovery rate of 99.4% and an aluminum recovery rate of 98.4%.

[0048] Application Example 2

[0049] This application example uses the hydrodynamic-eddy current copper-aluminum foil high-efficiency sorting system device described in Example 1. The high-efficiency sorting method includes:

[0050] 200 kg of crushed material was added to a hydrocyclone for hydrodynamic separation. The cone angle of the cyclone chamber was controlled at 40 ± 2 degrees, and the inlet pressure was maintained at 0.5 ± 0.05 MPa. This yielded 186.1 kg of electrode powder and 13.9 kg of hydrodynamically screened mixture, with an electrode powder shedding rate of 97.9%. Eddy current separation was then applied to the hydrodynamically screened mixture, maintaining a magnetic field strength of 20-25 T, a time gradient > 4000 T / s, and a deflection channel at a 30-degree angle to the perpendicular magnetic field direction. This ultimately yielded 6.0 kg of copper foil and 7.9 kg of aluminum foil, with a copper recovery rate of 99.6% and an aluminum recovery rate of 98%.

[0051] In the actual operation of this invention, the magnetic field strength and time gradient are precisely controlled through eddy current separation, causing the aluminum foil to be laterally deflected by eddy current force with a deflection distance ≥10cm, while the copper foil falls almost vertically. At this point, the copper and aluminum foils separate and are collected by a conveyor belt. Adjustable baffles are set within the deflection distance range (10-15cm) of the aluminum foil to ensure effective collection. This technology significantly improves the separation efficiency of copper and aluminum foils, achieving a copper recovery rate of up to 99.5% and an aluminum recovery rate of up to 98.2%, while reducing the entanglement rate to near zero. This technology avoids mechanical screening methods, and the hydrodynamic-eddy current separation system fundamentally reduces splashing. Furthermore, this technology can be remotely controlled, improving the safety of the production environment for workers. This technology effectively solves the problem of efficient separation of copper and aluminum foils while achieving safety and environmental protection goals.

[0052] In summary, this utility model provides a hydrodynamic-eddy current copper-aluminum foil high-efficiency sorting system, including a hydrodynamic sorting unit and an eddy current sorting unit connected in sequence. The key feature is that an adjustable baffle linked to a laser feedback unit is set at the outlet of the eddy current separator of the eddy current sorting unit. Based on the real-time monitoring of the aluminum foil offset distance by the laser feedback unit, the adjustable baffle can adjust the size of the aluminum foil collection port. This not only enables the separation of electrode powder and copper-aluminum foil in waste lithium batteries, but also achieves efficient separation between copper foil and aluminum foil, realizing the secondary utilization of copper and aluminum resources.
