[0049] Working principle: When in use, the invention connects the slurry inlet and outlet ends of the first four-way tube 10 and the second four-way tube 11 to the input and output ends of the electrolytic slurry respectively when the device is normally used for lithium extraction. At this time, the electrolytic slurry enters the electrolytic component 7 through the first four-way tube 10, the second connecting tube 404, the first connecting tube 403 and the liquid inlet hose 9 for lithium extraction. The slurry after lithium extraction is discharged outward through the liquid outlet hose 8, the third connecting tube 405, the fourth connecting tube 406 and the second four-way tube 11. When the slurry is located in the electrolytic component 7, the first power connection plate 723 and the second power connection plate 729 are connected to the positive and negative electrodes of the power supply, so that the wavy current collector 732 is energized. At this time, the waste battery slurry is pumped into the flow channel plate 726 through the liquid inlet hose 9, and the wavy current collector 732 improves the liquid charging performance and enhances the electrical adsorption effect, thereby improving the efficiency of extracting lithium ions from the waste battery slurry and greatly improving the lithium recovery rate of the waste battery.

[0050] When cleaning the electrolytic component 7, first connect the cleaning liquid inlet and outlet ends of the first four-way pipe 10 and the second four-way pipe 11 to the input and output ends of the cleaning liquid respectively. At this time, the cleaning liquid passes through the first four-way pipe 10, the second connecting pipe 404, the first connecting pipe 403 and the liquid inlet hose 9 and penetrates the electrolytic component 7 for cleaning. Since the interior of the second bellows 507 is connected to the interior of the first connecting pipe 403, a part of the cleaning liquid will remain in the interior of the second bellows 507. The cleaning liquid after cleaning is discharged outward through the liquid outlet hose 8, the third connecting pipe 405, the fourth connecting pipe 406 and the second four-way pipe 11. Since the third connecting pipe 405 is connected to the interior of the first bellows 502, a part of the cleaning liquid will also remain in the first bellows 502. Inside, since the second bellows 507 and the first bellows 502 do not expand at the same time, that is, when the first driving frame 501 moves upward and compresses the first bellows 502, the cleaning liquid inside the first bellows 502 will enter the liquid outlet hose 8, the electrolytic assembly 7 and the liquid inlet hose 9 through the third connecting pipe 405, and at the same time, it will enter the second bellows 507 through the first connecting pipe 403, and drive the second bellows 507 to expand, so that the second bellows 507 drives the second driving frame 506 to move upward, and squeezes the reset spring 505 and the telescopic rod 504. When the first driving frame 501 moves downward, under the action of the reset spring 505 and the telescopic rod 504, the cleaning liquid inside the second bellows 507 flows back to the inside of the first bellows 502;

[0051] In the above process, first, the first driving frame 501 moves up and down to squeeze and release the first bellows 502. Under the reset action of the reset spring 505 and the telescopic rod 504, the cleaning liquid inside the third connecting pipe 405, the liquid outlet hose 8, the electrolytic component 7, the liquid inlet hose 9 and the first connecting pipe 403 will be pressurized to flow back and forth, which can more effectively flush the structure inside the electrolytic component 7. In particular, for some stubborn scale attached to the tube wall or the plate, the reciprocating cleaning liquid can "stir" the fluid inside the electrolytic component 7 to a certain extent, increase the turbulence of the cleaning liquid, and help dissolve and discharge the scale. At the same time, the cleaning liquid reciprocates inside the electrolytic component 7, which can make the flow path of the cleaning liquid inside the electrolytic component 7 more complex and changeable, which helps to reduce the cleaning dead corners, and can accelerate the shedding and discharge of dirt, thereby improving the cleaning efficiency.

[0052] After cleaning with the cleaning liquid, the inside of the electrolytic component 7 is cleaned with acid by connecting the acid output end of the acid storage tank 3 to the acid inlet end of the first four-way pipe 10, and connecting the acid outlet end of the second four-way pipe 11 to the acid input end of the recovery tank 2, while the spoiler component and the drive component work at the same time, so that the acid can penetrate the electrolytic component 7 and reciprocate inside the electrolytic component 7 to pickle the inside of the electrolytic component 7, and the acid after pickling can be recovered through the recovery tank 2, and the pickling of the electrolytic component 7 can dissolve stubborn dirt, so that the cleaning is more thorough;

[0053] The up and down movement of the first driving frame 501 is driven by the driving assembly. When the driving assembly is in use, the driving motor 607 is energized to drive the driving gear 605 to rotate, and the driving gear 605 drives the driving gear ring 606 to rotate synchronously. When the tooth pattern on the surface of the driving gear 605 and the driven gear 602 meshes with the driven gear 602, the two driven gears 602 will rotate synchronously. When the two driven gears 602 rotate synchronously, the driven gear 602 will drive the two driven gears 606 to rotate synchronously through the rotating shaft 601. The two driving gear blocks 603 rotate synchronously in the same direction, so that the two driving gear blocks 603 are not meshed with the lifting gear plate 604 at the same time. As the driven gear 602 rotates, the lifting gear plate 604 moves up and down reciprocatingly. When the driven gear 602 rotates one circle, the lifting gear plate 604 moves up and down once, and the lifting gear plate 604 drives the first driving frame 501 to move up and down reciprocatingly through the connecting block, thereby achieving the purpose of driving the first driving frame 501 to move up and down to squeeze and release the first corrugated tube 502;

[0054] When the notch of the tooth pattern of the driving gear 605 and the driving gear ring 606 corresponds to the driven gear 602, the through hole 608 coincides with the connecting frame 609, and the cleaning liquid or slurry can be directly discharged through the liquid outlet hose 8, the third connecting pipe 405 and the fourth connecting pipe 406, so that in the process of cleaning or lithium extraction, the movement of the lithium extraction slurry or the cleaning liquid or the acid is generally that it first enters the inside of the electrolytic component 7 from the liquid inlet hose 9 and is discharged through the liquid outlet hose 8. In this process, when the driving gear 605 and the driving gear ring 606 drive the driven gear 602 to rotate, that is, when the first corrugated tube 502 is squeezed and contracted, the lithium extraction slurry or the cleaning liquid or the acid will reciprocate inside the electrolytic component 7, thereby improving the lithium extraction efficiency or the cleaning effect. When the notch in the middle of the tooth pattern of the driving gear 605 and the driving gear ring 606 corresponds to the driven gear 602, the lithium extraction slurry or the cleaning liquid or the acid normally enters the inside of the electrolytic component 7 through the liquid inlet hose 9 and is discharged through the liquid outlet hose 8.

[0055] In this embodiment, the metal titanium has the characteristics of light weight, high strength, easy processing, strong conductivity, etc. On the basis of the existing flow electrode electrochemical device, the current collector with the electrode liquid flow channel is replaced by a wavy titanium mesh stacked three-dimensional current collector electrode, that is, a structural wavy current collector 732, and the two side layers of the No. 1 connecting plate 723 use flat titanium mesh to increase the contact area between the current collector and the connecting plate and the ion exchange membrane, and improve the charging performance of the electrode liquid. The two middle layer titanium meshes are pressed into a sinusoidal curve by a mold, the waveform period is 20mm, the peak and trough heights are both 4mm, and the sinusoidal waveforms of the two wavy titanium meshes differ by half a cycle in phase, so that the peaks and troughs of the middle titanium mesh are relative when combined, thereby increasing the pores in the current collector. The wavy structure of the middle layer titanium mesh can significantly improve the flow performance of the electrode liquid inside the three-dimensional current collector, avoid the blockage of solids in the electrode liquid, and the flow of the electrode liquid in the wavy titanium mesh stacked three-dimensional current collector is more comprehensive, making the wavy current collector 7 The flow path of the electrode liquid in 32 is more disordered and uniform and is covered with the three-dimensional collector cross-section of the wavy titanium mesh stack, so that the contact area between the electrode liquid and the anion and cation membrane is maximized, thereby improving the ion adsorption capacity of the anion and cation membrane to the electrolyte passing through the flow channel plate 726, improving the desalination effect and the utilization efficiency of the anion and cation membrane. The process cost of this embodiment is low, but it has extremely strong ion adsorption capacity and excellent adsorption stability. It will not cause secondary environmental pollution and has broad development prospects. In addition, this embodiment can also clean the wavy collector 732, that is, the two ends of the No. 1 flow electrode circulation tube 733 and the two ends of the No. 2 flow electrode circulation tube 734 are not fixed to the inlet and outlet ends of the first four-way tube 10 and the second four-way tube 11 at the same time, and the wavy collector 732 is cleaned by a cleaning liquid or an acid solution, and the liquid outlet hose 8 and the liquid inlet hose 9 are respectively fixed to the inlet and outlet ends of the first four-way tube 10 and the second four-way tube 11, and the inside of the flow channel plate 726 can also be cleaned. Embodiment 2

Embodiment 3

[0057] See also Fig.11, which is different from the first embodiment, is that the wavy current collector 732 is composed of two flat titanium meshes and two pressed wavy titanium meshes stacked alternately, the wavy titanium mesh corrugations are perpendicular to the liquid flow direction, and are fixed by perforating with titanium wires. The wavy titanium mesh perpendicular to the liquid flow direction makes the turbulence of the electrode liquid flowing therethrough more sufficient, significantly improving the flow performance of the electrode liquid inside the three-dimensional current collector. The alternating combination of the flat titanium mesh and the wavy titanium mesh effectively increases the pores in the current collector and avoids clogging of solids in the electrode liquid. Embodiment 4

[0058] See also Fig.12 , which is different from the first embodiment, is that the wavy current collector 732 is composed of two planar titanium meshes sandwiching two wavy titanium meshes, and the directions of the waves of the two wavy titanium meshes are parallel to each other, the waves of the two wavy titanium meshes are perpendicular to the flow direction of the liquid, and are fixed by perforating with titanium wires. The wavy titanium meshes perpendicular to the flow direction of the liquid make the turbulence of the electrode liquid therein more sufficient, significantly improve the flow performance of the electrode liquid inside the three-dimensional current collector, and avoid the blockage of solids in the electrode liquid. The two side layers use planar titanium meshes to increase the contact area between the current collector and the connecting plate and the ion exchange membrane, thereby improving the charging performance of the electrode liquid.
