[0027] Example 1

[0028] In one embodiment, such as Figures 1-5 As shown, the waste lithium-ion power battery live-line crushing device includes:

[0029] Rack 1;

[0030] The collection box 2 is located on the upper surface of the frame 1;

[0031] Crushing box 3 is connected to the upper end of collecting box 2;

[0032] Connecting box 4, which is connected to the upper end of crushing box 3;

[0033] The feed hopper 5 is connected to the upper end of the connecting box 4;

[0034] A circulating cooling assembly is used to circulate and transport the liquid at the bottom of the collection box 2 to the interior of the connecting box 4, and is disposed between the collection box 2 and the connecting box 4. The circulating cooling assembly includes a circulation pipe 6, one end of which is connected to the lower side wall of the collection box 2 and extends into the interior of the collection box 2, and the other end of which is connected to the side wall of the connecting box 4 and extends into the interior of the connecting box 4. A first water pump 7 is installed on the circulation pipe 6, and a cooling component is provided on the circulation pipe 6.

[0035] The cooling component includes a cooling cylinder 8, which is sleeved on the outer wall of the circulation pipe 6. A conveying pipe 9 is connected to the upper end wall of the cooling cylinder 8, and the other end of the conveying pipe 9 is connected to the bottom end wall of the cooling cylinder 8. A second water pump 10 is installed on the conveying pipe 9, and two sets of refrigeration mechanisms 11 are provided on the bottom inner wall of the cooling cylinder 8.

[0036] Specifically, before the crushing device starts operating, liquid, such as water, alkaline solution, mineral oil, transformer oil, fluorinated alkanes, or hydrofluoroethers, is poured into the crushing device to fill the collection box 2, crushing box 3, and connecting box 4. Waste lithium-ion power batteries are fed through the feeding hopper 5 and enter the crushing box 3 through the connecting box 4. The crushed power batteries fall onto the filter plate 12 and are then discharged through the discharge collector 13. Simultaneously, the first water pump 7 is started, causing the liquid at the bottom of the collection box 2 to be re-transported to the connecting box 4 through the circulation pipe 6. This allows the liquid to carry the material inside the crushing box 3 back into the collection box 2, preventing material blockage inside the crushing box 3. At the same time, two sets of cooling mechanisms 11 and the second water pump 10 are started. The two sets of cooling mechanisms 11 cool the coolant inside the cooling cylinder 8, and the second water pump 10 cools the coolant inside the cooling cylinder 8. The feed pipe 9 transports the coolant from the upper part of the cooling cylinder 8 to the bottom of the cooling cylinder 8, allowing the coolant inside the cooling cylinder 8 to be evenly distributed and cooled. This improves the cooling effect of the coolant inside the circulation pipe 6, thereby reducing the temperature inside the collection box 2, crushing box 3, and connecting box 4, and improving the safety of the power battery in case of breakage. By setting up a circulation cooling assembly consisting of circulation pipe 6, first water pump 7, and cooling components, the liquid at the bottom of the collection box 2 can be transported to the inside of the connecting box 4 through circulation pipe 6, so that the liquid is in a downward flow state. This allows the material inside the crushing box 3 to fall into the inside of the collection box 2, preventing blockage inside the crushing box 3. At the same time, the cooling cylinder 8 can cool the liquid inside the circulation pipe 6, thereby reducing the temperature inside the collection box 2, crushing box 3, and connecting box 4, and improving the safety of the power battery in case of breakage.

[0037] like Figures 1-5 As shown, a filter plate 12 is installed on the inner wall of the collection box 2, and the filter plate 12 is inclined. A discharge collector 13 is installed on one outer wall of the collection box 2. The filter plate 12 can filter the crushed power battery, and the discharge collector 13 can discharge the crushed power battery. A drain pipe 14 is installed below the discharge collector 13. The drain pipe 14 is connected to the side wall of the collection box 2 and extends into the interior of the collection box 2. A control valve 15 is installed on the drain pipe 14. The drain pipe 14 and the control valve 15 can discharge the liquid inside the collection box 2. A support block 23 is installed on the outer wall of the cooling cylinder 8 and is connected to one outer wall of the collection box 2. The support block 23 can support the cooling cylinder 8.

[0038] Example 2

[0039] like Figures 1-4 As shown, a base 16 is provided on one outer wall of the crushing box 3, and a crushing motor 17 is installed on the base 16. The output end of the crushing motor 17 passes through the side wall of the crushing box 3 and is connected to a first gear 18. A second gear 19 is meshed on one side of the first gear 18. Both the first gear 18 and the second gear 19 are rotatably connected to the inner wall of the crushing box 3. A set of rotating rods 20 is provided on the side wall of both the first gear 18 and the second gear 19. A set of crushing rollers 21 is sleeved on the outer wall of both sets of rotating rods 20. A protective box 22 is provided on one inner wall of the crushing box 3. The protective box 22 is located outside the first gear 18 and the second gear 19, and one side wall of the protective box 22 is rotatably connected to the outer wall of the two sets of rotating rods 20. When the crushing motor 17 is started, the crushing motor 17 drives the first gear 18 to rotate, and the first gear 18 drives the second gear 19 to rotate, so that the two sets of rotating rods 20 drive the two sets of crushing rollers 21 to rotate, thereby crushing the power battery and improving the crushing effect of the power battery.

[0040] The above embodiments disclose a live-line crushing device for waste lithium-ion power batteries. Before the crushing device operates, a liquid, such as water, alkaline solution, mineral oil, transformer oil, fluorinated alkanes, or hydrofluoroether, is poured into the crushing device to fill the collection box 2, crushing box 3, and connecting box 4. Waste lithium-ion power batteries are fed through the feeding hopper 5 and enter the crushing box 3 through the connecting box 4. Then, the crushing motor 17 is started, which drives the first gear 18 to rotate. The first gear 18 drives the second gear 19 to rotate, causing the two sets of rotating rods 20 to drive the two sets of crushing rollers 21 to rotate, thereby crushing the power batteries. The crushed power batteries fall onto the filter plate 12 and then pass through the discharge collector 1. 3. Discharge material; simultaneously, start the first water pump 7, so that the liquid at the bottom of the collection box 2 is transported back to the inside of the connecting box 4 through the circulation pipe 6, so that the liquid can carry the material inside the crushing box 3 into the inside of the collection box 2, avoiding material blockage inside the crushing box 3; at the same time, start the two sets of cooling mechanisms 11 and the second water pump 10. The two sets of cooling mechanisms 11 cool the coolant inside the cooling cylinder 8, and the second water pump 10 transports the coolant at the top of the cooling cylinder 8 to the bottom of the cooling cylinder 8 through the conveying pipe 9, so that the coolant inside the cooling cylinder 8 can be cooled and distributed evenly, thereby improving the cooling effect of the coolant inside the circulation pipe 6, thereby reducing the temperature inside the collection box 2, crushing box 3 and connecting box 4, and improving the safety of power battery breakage.
