[0035] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0037] It can be understood that the regeneration repair chamber 110 formed in the repair box 100 is used to hold the waste electrode positive electrode material, lithium salt, hydrogen bond co-agent and detergent; since the bottom of the regeneration repair chamber 110 is respectively provided with a discharge hole 111 and a liquid discharge hole 112, the discharge hole 111 is convenient for the smooth discharge of the waste electrode positive electrode material after the repair is completed, and the liquid discharge hole 112 is convenient for discharging the liquid in the repair box 100, such as the detergent after washing the waste electrode positive electrode material; since the positive electrode powder inlet pipe 210, the detergent inlet pipe 220, the co-agent inlet pipe 230 and the lithium salt inlet pipe 240 are The tubes 240 are respectively connected to the regeneration repair chamber 110, so that the hydrogen bond co-agent and the lithium salt enter the regeneration repair chamber 110 through the co-agent inlet tube 230 and the lithium salt inlet tube 240 respectively, and the stirring component 400 is started to prepare a low eutectic solvent in the regeneration repair chamber 110, and the waste electrode positive electrode material enters the regeneration repair chamber 110 through the positive electrode powder inlet tube 210, so that the waste electrode positive electrode material reacts with the low eutectic solvent to achieve mixed repair of the waste electrode positive electrode material; then, detergent is introduced into the detergent tube, and at the same time, the stirring component 400 is cooperated to make The detergent can wash away the impurities and excess eutectic solvent adhering to the surface of the regenerated positive electrode material; then, when the mixed repair operation of the waste electrode positive electrode material is completed, since the first filter press plate and the second filter press plate are arranged in parallel with each other and are respectively located on both sides of the stirring component 400, when the filter press component is running, the first filter press plate 510 and the second filter press plate 520 are respectively slidably connected to the inner walls on both sides of the regeneration repair chamber 110, so as to realize the filter pressing treatment of the washed waste electrode positive electrode material mixture; the filtrate after the filter pressing is passed through the first filter press plate 510 and the second filter press plate 520; The multiple filter holes opened in the second filter press plate 520 pass through and are discharged from the liquid outlet 112, while the filter cake remains in the regeneration repair chamber 110; then the heating component and the stirring component 400 are started, so that the stirring component 400 can realize the crushing operation of the filter cake. At the same time, the use of the heating component is used to accelerate the sintering of the regenerated waste electrode positive material, so that the low eutectic solvent preparation, mixed repair, washing, filter pressing and sintering operations of the waste electrode positive material are completed in the regeneration repair chamber 110, which simplifies the structure of the regeneration repair device and occupies a smaller area.

[0038] like Figure 2As shown, in one embodiment, the stirring assembly 400 includes a rotating shaft 410, a motor 440, at least one first rotating rod 420 and at least one second rotating rod 430. The rotating shaft 410 is rotatably arranged in the middle of the regeneration and repair chamber 110, and the rotating shaft 410 is connected to the driving end of the motor 440; each first rotating rod 420 and the corresponding second rotating rod 430 are symmetrically arranged along the central axis of the rotating shaft 410, and the extension direction of the first rotating rod 420 and the extension direction of the second rotating rod 430 are in the same plane; when the filter press assembly is running, the first filter press plate 510 and the second filter press plate 520 are parallel to the plane where the extension direction of the first rotating rod 420 is located. It can be understood that since a rotating shaft 410 is provided in the middle of the regeneration and repair chamber 110, the rotating shaft 410 is connected to the driving end of the motor 440, and when the motor 440 is driven, the rotating shaft 410 is driven to rotate to realize the stirring function; since the first rotating rod 420 and the second rotating rod 430 are symmetrically arranged along the central axis of the rotating shaft 410 and the extension direction of the first rotating rod 420 and the extension direction of the second rotating rod 430 are in the same plane, the first rotating rod 420 and the second rotating rod 430 are located in the same plane. During filter pressing, start the motor 440 so that the extension direction of the first rotating rod 420 and the extension direction of the second rotating rod 430 are perpendicular to the pressing direction of the first filter press plate 510 and the pressing direction of the second filter press plate 520, which is the preset non-interference position of the stirring assembly 400 and the filter press assembly 500. Under the action of the driver, the first filter press plate 510 and the second filter press plate 520 can fully extrude and filter the washed waste electrode positive electrode material mixture, avoiding the interference between the first rotating rod 420 and the second rotating rod 430 of the stirring assembly 400 and affecting the extrusion filtration effect.

[0039] In one embodiment, the number of the first rotating rods 420 and the number of the second rotating rods 430 are both multiple, and the multiple first rotating rods 420 are arranged at intervals along the extension direction of the rotating shaft 410. The multiple first rotating rods 420 and the multiple second rotating rods 430 are arranged one by one to achieve mixing and stirring of the positive electrode material of the waste electrode sheet and the low eutectic solvent.

[0040] In one embodiment, the waste electrode sheet positive electrode material regeneration and repair device 10 further includes a material discharge cover plate 900, which is detachably arranged at the discharge hole 111. Since the discharge hole 111 is located below the rotating shaft 410, the material discharge cover plate 900 needs to close the discharge hole 111 when the material is not discharged, so as to prevent the waste electrode sheet positive electrode material from leaking from the discharge hole 111 when the washing, filter pressing and sintering processes are not completed, thereby affecting the repair efficiency.

[0041] like Figure 2As shown, in one embodiment, the waste electrode positive material regeneration and repair device 10 also includes a first drive assembly 600, which includes a first driver 610 and a first telescopic rod 620. The driving end of the first driver 610 is connected to the first end of the first telescopic rod 620.

When the first driver 610 is started, the first telescopic rod 620 can slide in the first sliding hole 113, so that the first filter press plate 510 can be set to slide on the first side inner wall of the regeneration and repair chamber 110.

[0042] Likewise, if Figure 2 As shown, in one embodiment, the waste electrode positive material regeneration and repair device 10 further includes a second drive assembly 700, the second drive assembly 700 includes a second driver 710 and a second telescopic rod 720, the driving end of the second driver 710 is connected to the first end of the second telescopic rod 720, the second side inner wall arranged opposite to the first side inner wall of the regeneration and repair chamber 110 is provided with a second sliding hole (not shown), the second end of the second telescopic rod 720 passes through the second sliding hole (not shown) and is connected to the second filter press plate 520, so that the second filter press plate 520 is slidably arranged on the second side inner wall of the regeneration and repair chamber 110. Since the second side inner wall and the first side inner wall are arranged opposite to each other, the first filter press plate 510 and the second filter press plate 520 can form an extrusion chamber under the use of the first driver 610 and the second driver 710, thereby realizing the filter pressing operation of the waste electrode positive material mixture in the regeneration and repair chamber 110.

[0043] In one embodiment, the waste electrode positive material regeneration and repair device 10 further includes a support seat 800, the support seat 800 is provided with a mounting hole 810, and the first telescopic rod 620 or the second telescopic rod 720 is arranged in the mounting hole 810. It can be understood that the support seat 800 is provided with a mounting hole 810, so that the first telescopic rod 620 or the second telescopic rod 720 is adapted to the mounting hole 810, so as to facilitate supporting and fixing the first telescopic rod 620 or the second telescopic rod 720, and prevent the first telescopic rod 620 and the second telescopic rod 720 from loosening when the driver is started to affect the filter pressing effect.

[0044] In one embodiment, the heating assembly includes a plurality of heating wires 300, each of which is disposed around the inner wall of the regeneration repair cavity 110. A receiving cavity is formed in the side wall of the regeneration repair cavity 110, and the plurality of heating wires 300 are disposed around the length direction of the receiving cavity to ensure uniform heating of the regeneration repair cavity 110, thereby improving the sufficiency and uniformity of the sintering of the positive electrode material of the waste electrode sheet.

[0045] like Figure 3As shown, in one embodiment, the waste electrode positive material regeneration and repair device 10 further includes a filter plate 120, and the filter plate 120 is clamped at the liquid outlet 112. The additional filter plate 120 realizes the separation of the detergent and the waste electrode positive material, and avoids the loss of the waste electrode positive material. In addition, the filter plate 120 is clamped at the liquid outlet 112, which is convenient for the operator to disassemble and assemble the filter plate 120, thereby reducing the difficulty of cleaning the filter plate 120.

[0046] like Figure 3 and Figure 4 As shown, in one embodiment, the waste electrode positive material regeneration and repair device 10 further includes a liquid outlet pipe 130, which is arranged at the liquid outlet hole 112, and a valve body 131 is arranged on the liquid outlet pipe 130. The valve body 131 is used to control the discharge of liquid from the liquid outlet pipe 130.

[0047] The present disclosure also provides a waste electrode positive material regeneration device 1, comprising any of the waste electrode positive material regeneration and repair devices 10 described above.

[0048] During operation, the crushing box 20 crushes the waste electrode sheet positive electrode material by rotating the crushing tool to obtain 1cm-2cm waste electrode sheet positive electrode material powder; the waste electrode sheet positive electrode material powder is input into the alkali dissolving tank 30, and then the alkali solution (NaOH solution, LiOH solution) is input into the alkali dissolving tank 30, and the alkali solution reacts with the waste electrode sheet positive electrode material powder to remove the metal ions (Li + 、Ni 2+ 、Co 2+ , Mn 2+ The metal ion-containing alkaline solution is input into the impurity removal box 40, and the impurity removal box 40 is heated to between 600 degrees and 640 degrees to effectively remove impurities such as binders and plastics, and then the waste electrode positive electrode material after impurity removal is input into the repair box 100 through the positive electrode powder inlet pipe 210 for repair and regeneration.

[0049] Compared with the prior art, the present invention has at least the following advantages:

[0050] 1) Since the first filter press plate 510 and the second filter press plate 520 are respectively slidably connected to the inner walls on both sides of the regeneration and repair chamber 110, the first filter press plate 510 and the second filter press plate 520 are both located in the regeneration and repair chamber 110; and since when the filter press assembly 500 is in operation, the first filter press plate 510 and the second filter press plate 520 are arranged in parallel with each other and are respectively located on both sides of the stirring assembly 400, the first filter press plate 510 and the second filter press plate 520 can squeeze and filter the washed waste electrode positive material mixture under the action of the driver, and the stirring, washing and filter pressing are completed in the same chamber. In this way, on the one hand, the problem of material loss caused by the waste electrode positive material mixture adhering to the pipe wall during the required transfer process of stirring, washing and filter pressing in different chambers is avoided, thereby improving the recycling rate of the waste electrode positive material. On the other hand, the connection of the pipeline is reduced, so that the area of ​​the regeneration and repair device is small and the structure is more compact.

[0051] 2) Since the positive electrode powder inlet pipe 210, the detergent inlet pipe 220, the common body inlet pipe 230 and the lithium salt inlet pipe 240 are respectively connected to the regeneration and repair chamber 110, and since the inner wall of the regeneration and repair chamber 110 is provided with a heating component, the stirring component 400 is rotatably arranged in the regeneration and repair chamber 110, so that the positive electrode powder inlet pipe 210, the detergent inlet pipe 220, the common body inlet pipe 230, the lithium salt inlet pipe 240, the heating component and the stirring component 400 are integrated in the repair box 100, so that the low eutectic solvent preparation, mixed repair, washing, filter pressing and sintering are all completed in the regeneration and repair chamber 110, which simplifies the structure of the regeneration and repair device and occupies a smaller area.
