[0037] It should be noted that, in this embodiment, during electrolysis, the moving feed component 23 adds electrolyte and reducing agent into the electrolysis chamber 22. The first electrolysis rod 25 and the second electrolysis rod 263 are simultaneously energized. Lead metal is deposited on the surface of the second electrolysis rod 263. When enough lead metal is deposited on the surface of the second electrolysis rod 263, the stepper motor 26 drives the rotating disk 261 to rotate 180 degrees. At this time, the stripping and recycling component 27 recycles the lead metal on the surface of the second electrolysis rod 263. The auxiliary moving component 28 drives the second electrolysis rod 263 to move down so that the second electrolysis rod 263 is reset. After electrolysis is completed, the sorting and discharging component 24 sorts and discharges the electrolyte and waste residue.

[0038] Furthermore, when the moving feeding component 23 is working, the first linear guide rail 231 drives the feeding nozzle 234 to move, and the drive motor 232 drives the feeding nozzle 234 to rotate, so that the feeding nozzle 234 is in the corresponding electrolysis chamber 22, and the raw material enters the corresponding electrolysis chamber 22 after passing through the feeding pipe 235 and the feeding nozzle 234.

[0039] Furthermore, when the stripping and recycling component 27 is working, the first telescopic cylinder 272 drives the lead stripping box 275 to move along the Y-axis direction, and the second telescopic cylinder 274 drives the lead stripping box 275 to move along the X-axis direction.

[0040] Furthermore, when the sorting and discharging component 24 is working, the drive cylinder 244 drives the baffle 243 to move so that the filter screen 245 coincides with the discharge port 241. The electrolyte is discharged after being filtered through the filter screen 245. After the electrolyte is discharged, the drive cylinder 244 drives the baffle 243 to continue to move down so that the discharge port 241 is in an open state. At this time, the servo motor 247 drives the unloading tilting plate 246 to rotate so that the waste residue is discharged through the discharge port 241.

[0042] It should be noted that in this embodiment, the battery panels on the feed plate 42 are transmitted by the feed plate 42 and crushed by the crusher 43 before entering the feed disc 41. When one of the electrolysis chambers 22 needs to add crushed battery panels, the first drive motor 442 drives the opening and closing disc 443 to rotate so that the feed through hole 4431 coincides with the corresponding feed hole 411. The crushed battery panels enter the corresponding electrolysis chamber 22 after passing through the feed hole 411 and the feed through hole 4431.

[0043] Furthermore, the feeding component 45 can move the crushed battery plate on the feeding disc 41 to facilitate feeding.

[0046] Furthermore, when the battery fixing component 33 is working, the actuator of the pneumatic cylinder 331 drives the clamping plate 332 to move, and the clamping plate 332 clamps and fixes the lead-acid battery.

[0047] Furthermore, when the electrolyte recovery component 32 is working, the actuator of the electric cylinder 321 drives the negative pressure box 322 to move until the needle 323 pierces into the lead-acid battery casing. At this time, the negative pressure tube 324 draws out the electrolyte in the battery.

[0048] Furthermore, when the mobile battery panel disassembly component 34 is working, the actuator of the cylinder 344 drives the disassembly box 343 to move downward so that the disassembly box 343 covers the outside of the lead-acid battery. The pneumatic cylinder 345 drives the cutter head 346 to move to break the side wall of the lead-acid battery so as to remove the top cover. After removal, the pneumatic cylinder 345 drives the cutter head 346 to move to clamp the battery panel. After clamping, the cylinder 344 drives the disassembly box 343 to reset. The second linear guide rail 341 drives the disassembly box 343 to move onto the feeding plate 42. The pneumatic cylinder 345 drives the cutter head 346 to reset, and the battery panel falls onto the feeding plate 42.

[0049] The specific process of this invention is as follows:

[0050] The waste lead-acid battery is placed on the dismantling platform 10. The battery fixing component 33 positions and fixes the lead-acid battery. After fixing, the electrolyte recovery component 32 draws out the electrolyte from the lead-acid battery. After the drawing is completed, the mobile battery panel dismantling component 34 breaks the top cover of the lead-acid battery. After breaking, the battery panel is taken out and transported to the feeding plate 42. The lead-acid battery casing with the battery panel removed is removed by the conveyor belt on the dismantling platform 10, and the next lead-acid battery can be dismantled.

[0051] When the battery fixing component 33 is working, the actuator of the pneumatic cylinder 331 drives the clamping plate 332 to move, and the clamping plate 332 clamps and fixes the lead-acid battery.

[0052] When the electrolyte recovery component 32 is working, the actuator of the electric cylinder 321 drives the negative pressure box 322 to move until the needle 323 pierces the lead-acid battery casing. At this time, the negative pressure tube 324 draws out the electrolyte in the battery.

[0053] When the mobile battery panel disassembly component 34 is working, the actuator of the cylinder 344 drives the disassembly box 343 to move down so that the disassembly box 343 covers the outside of the lead-acid battery. The pneumatic cylinder 345 drives the cutter head 346 to move to break the side wall of the lead-acid battery so as to remove the top cover. After removal, the pneumatic cylinder 345 drives the cutter head 346 to move to clamp the battery panel. After clamping, the cylinder 344 drives the disassembly box 343 to reset. The second linear guide rail 341 drives the disassembly box 343 to move onto the feeding plate 42. The pneumatic cylinder 345 drives the cutter head 346 to reset, and the battery panel falls onto the feeding plate 42.

[0054] The solar panels on the feed plate 42 are transported by the feed plate 42 and crushed by the crusher 43 before entering the feed disc 41. When one of the electrolysis chambers 22 needs to add crushed solar panels, the first drive motor 442 drives the opening and closing disc 443 to rotate so that the feed through hole 4431 coincides with the corresponding feed hole 411. The crushed solar panels enter the corresponding electrolysis chamber 22 after passing through the feed hole 411 and the feed through hole 4431.

[0055] The feeding component 45 can move the crushed battery plate on the feeding disc 41 to facilitate feeding. When the feeding component 45 is in use, the second drive motor 451 drives the connecting rod 452 to rotate, and the connecting rod 452 moves the crushed battery plate through the feeding plate 453.

[0056] During electrolysis, the moving feed component 23 adds electrolyte and reducing agent into the electrolysis chamber 22. The first electrolysis rod 25 and the second electrolysis rod 263 are energized simultaneously. Lead metal is deposited on the surface of the second electrolysis rod 263. When enough lead metal is deposited on the surface of the second electrolysis rod 263, the stepper motor 26 drives the rotating disk 261 to rotate 180 degrees. At this time, the stripping and recycling component 27 recovers the lead metal on the surface of the second electrolysis rod 263. The auxiliary moving component 28 drives the second electrolysis rod 263 to move down so that the second electrolysis rod 263 is reset. After electrolysis is completed, the sorting and discharging component 24 sorts and discharges the electrolyte and waste residue.

[0057] When the moving feeding component 23 is working, the first linear guide rail 231 drives the feeding nozzle 234 to move, and the drive motor 232 drives the feeding nozzle 234 to rotate, so that the feeding nozzle 234 is in the corresponding electrolysis chamber 22. The raw material enters the corresponding electrolysis chamber 22 after passing through the feeding pipe 235 and the feeding nozzle 234.

[0058] When the stripping and recycling component 27 is working, the first telescopic cylinder 272 drives the lead stripping box 275 to move along the Y-axis, and the second telescopic cylinder 274 drives the lead stripping box 275 to move along the X-axis. After both lead stripping boxes 275 come into contact with the outer wall of the second electrolytic rod 263, the actuator of the hydraulic cylinder 282 drives the second electrolytic rod 263 to move downward, and the precipitated metallic lead falls into the lead stripping box 275. The negative pressure transmission pipe 276 can collect the finished metallic lead in the lead stripping box 275.

[0059] When the sorting and discharging component 24 is working, the drive cylinder 244 drives the baffle 243 to move so that the filter screen 245 coincides with the discharge port 241. The electrolyte is discharged after being filtered through the filter screen 245. After the electrolyte is discharged, the drive cylinder 244 drives the baffle 243 to continue to move down so that the discharge port 241 is in an open state. At this time, the servo motor 247 drives the unloading tilting plate 246 to rotate so that the waste residue is discharged through the discharge port 241.
