[0027] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0028] Please refer to the reference. Figures 1 to 3 This utility model provides a lithium battery recycling device (not shown) for recycling lithium batteries. It can completely remove battery powder from the current collector surface, enhancing the separation effect, increasing the battery powder recovery rate, and improving economic benefits.

[0029] The lithium battery recycling equipment includes a pyrometallurgical unit (not shown) and a powder stripping unit 100. The pyrometallurgical unit and the powder stripping unit 100 are arranged sequentially. The pyrometallurgical unit is used to sinter the electrode 200 at high temperature, and the powder stripping unit 100 is used to strip the powder from the sintered electrode 200 to separate the current collector and the battery powder.

[0030] The powder separation device 100 includes a frame 110 and a linear vibrating screen 120 and an impact mechanism 130 mounted on the frame 110. The impact mechanism 130 is positioned above the linear vibrating screen 120. The linear vibrating screen 120 conveys the electrode sheets 200 along a first direction and flattens multiple electrode sheets 200 to prevent overlap. The impact mechanism 130 impacts the electrode sheets 200 on the linear vibrating screen 120 along a second direction, separating the electrode sheets 200 into current collectors and battery powder. The linear vibrating screen 120 also drives the electrode sheets 200 to vibrate, further aiding in the separation of current collectors and battery powder. After the current collectors and battery powder are separated, the linear vibrating screen 120 also drives the current collectors and battery powder to discharge along the first direction, achieving rapid discharge and improving separation efficiency. Specifically, the first direction is perpendicular to the second direction to improve impact efficiency and impact effect, thereby achieving complete stripping of battery powder from the current collector surface, enhancing separation effect, improving battery powder recovery rate, and increasing economic benefits.

[0031] In this embodiment, the first direction is located on a horizontal plane, the second direction is vertical, the linear vibrating screen 120 is set horizontally, the linear vibrating screen 120 can drive the electrode 200 to move forward in the horizontal direction, and the impact mechanism 130 can impact the electrode 200 in the vertical direction so that the electrode 200 is separated into current collector and battery powder.

[0032] In this embodiment, the frame 110 includes a first frame 111 and a second frame 112. The first frame 111 and the second frame 112 are separately configured. The linear vibrating screen 120 is mounted on the first frame 111, and the impact mechanism 130 is mounted on the second frame 112, facilitating the removal of the impact mechanism 130 from the linear vibrating screen 120 for easier cleaning and maintenance. However, this is not the only embodiment; in other embodiments, the first frame 111 and the second frame 112 can be integrally configured.

[0033] Please refer to the reference. Figures 4 to 6 The impact mechanism 130 includes a mounting plate 131, a first drive member 132, a transmission assembly 133, a sliding plate 134, and an impact assembly 135. The mounting plate 131 is connected to the second frame 112. The first drive member 132 is mounted on the mounting plate 131 and connected to the sliding plate 134 via the transmission assembly 133. The sliding plate 134 is connected to the impact assembly 135. The first drive member 132 can drive the sliding plate 134 to move up and down in a second direction via the transmission assembly 133, thereby causing the impact assembly 135 to impact the electrode 200, so that the electrode 200 is separated into current collector and battery powder.

[0034] Optionally, the transmission assembly 133 includes an eccentric disk 1331 and a connecting rod 1332. The first driving member 132 is connected to the eccentric disk 1331, one end of the connecting rod 1332 is rotatably connected to the eccentric disk 1331, and the other end is rotatably connected to the slide plate 134. The first driving member 132 is used to drive the eccentric disk 1331 to rotate, thereby driving the slide plate 134 to move up and down in the second direction through the connecting rod 1332, and further driving the impact assembly 135 to move up and down in the second direction.

[0035] Optionally, the mounting plate 131 is provided with a guide rail 1311, which extends along the second direction. The slide plate 134 is provided with a slider 1341, which slides in cooperation with the guide rail 1311. The slider 1341 can slide relative to the guide rail 1311. The guide rail 1311 can guide and limit the slider 1341, thereby limiting the slide plate 134 and ensuring that the slide plate 134 can only slide up and down along the second direction, thus improving the stability of the movement of the slide plate 134 and the impact component 135.

[0036] In this embodiment, there are two guide rails 1311 and two sliders 1341. The two guide rails 1311 are arranged opposite to each other at both ends of the mounting plate 131. The transmission component 133 is arranged between the two guide rails 1311. Each slider 1341 slides with one guide rail 1311 to further improve the limiting effect on the slide plate 134 and ensure the stability of the slide plate 134 movement.

[0037] The impact assembly 135 includes a fixed beam 1351, a mounting beam 1352, a connecting rod 1353, and an impact ball 1354. The fixed beam 1351 is connected to the sliding plate 134, and the fixed beam 1351 is connected to the mounting beam 1352 via the connecting rod 1353. The impact ball 1354 is mounted on the mounting beam 1352 and is used to impact the electrode 200. The sliding plate 134 can drive the fixed beam 1351 to move up and down in a second direction, thereby driving the mounting beam 1352 and the impact ball 1354 to move up and down in the second direction via the connecting rod 1353, so that the impact ball 1354 impacts the electrode 200.

[0038] In this embodiment, the impact ball 1354 is made of plastic to ensure the integrity of the current collector and to prevent the impact ball 1354 material from adhering to the battery powder and causing an increase in the impurity content of the battery powder.

[0039] Optionally, the impact assembly 135 also includes an elastic element 1355. A stop head 1356 is provided at the end of the connecting rod 1353. The cross-sectional area of ​​the stop head 1356 is larger than that of the connecting rod 1353. The elastic element 1355 is sleeved on the connecting rod 1353. One end of the elastic element 1355 abuts against the stop head 1356, and the other end abuts against the side of the fixed beam 1351 away from the mounting beam 1352, thereby achieving flexible contact between the impact ball 1354 and the linear vibrating screen 120, preventing damage to the linear vibrating screen 120 from the impact ball 1354. Specifically, during the downward sliding of the slide plate 134 driven by the first driving component 132 through the transmission assembly 133, the fixed beam 1351, mounting beam 1352, connecting rod 1353, elastic element 1355, and impact ball 1354 all move downward until the impact ball 1354 contacts the electrode plate 200 on the linear vibrating screen 120. At this time, the slide plate 134 drives the fixed beam 1351 to continue moving downward, while the mounting beam 1352, connecting rod 1353, and impact ball 1354 remain stationary, and the elastic element 1355 is deformed under tension; when the slide plate 1354 moves downward, the fixed beam 1351 continues to move ... fixed beam 1351, mounting rod 1352, connecting rod 1353, and impact ball 1354 remain stationary, and the elastic element 1355 is deformed under tension. When the plate 134 moves downward to its limit position, the fixed beam 1351 is at its lowest position. During the process of the first driving member 132 driving the slide plate 134 to slide upward through the transmission assembly 133, the fixed beam 1351 moves upward, while the mounting beam 1352, the connecting rod 1353 and the impact ball 1354 remain stationary. At this time, the elastic element 1355 shortens and resets. After the elastic element 1355 has reset, the fixed beam 1351, the mounting beam 1352, the connecting rod 1353, the elastic element 1355 and the impact ball 1354 all move upward.

[0040] Optionally, the impact assembly 135 also includes a limiting strip 1357. The limiting strip 1357 is spaced apart on the side of the mounting beam 1352 away from the fixed beam 1351 and is screwed to the mounting beam 1352. The impact ball 1354 is installed between the mounting beam 1352 and the limiting strip 1357. The mounting beam 1352 and the limiting strip 1357 work together to fix and limit the position of the impact ball 1354, preventing the impact ball 1354 from detaching from the mounting beam 1352.

[0041] Furthermore, the mounting beam 1352 has a first clearance opening 1358, and the limiting strip 1357 has a second clearance opening 1359. The areas of the first clearance opening 1358 and the second clearance opening 1359 are both smaller than the diameter of the impact ball 1354. The impact ball 1354 is partially protruding from the first clearance opening 1358 and the second clearance opening 1359. The first clearance opening 1358 and the second clearance opening 1359 work together to improve the limiting effect on the impact ball 1354. The part of the impact ball 1354 protruding from the second clearance opening 1359 is used to impact the electrode 200.

[0042] In this embodiment, there are multiple connecting rods 1353 and elastic elements 1355 to enhance the flexible contact effect between the impact balls 1354 and the linear vibrating screen 120. There are also multiple impact balls 1354, first clearance openings 1358, and second clearance openings 1359. These multiple impact balls 1354 are spaced apart along a third direction to increase the impact area of ​​the impact balls 1354 and improve powder stripping efficiency. Specifically, the first direction, the second direction, and the third direction are perpendicular to each other to further improve powder stripping efficiency and increase battery powder recovery rate.

[0043] In this embodiment, the number of impact mechanisms 130 is one, but it is not limited to this. In other embodiments, the number of impact mechanisms 130 can be two or three. The number of impact mechanisms 130 is not specifically limited. Multiple impact mechanisms 130 are arranged at intervals along the first direction. Multiple impact mechanisms 130 work together to further improve the powder stripping efficiency and improve the battery powder recovery rate.

[0044] Please refer to the reference. Figure 1 and Figure 3 Optionally, the powder stripping device 100 further includes a translation mechanism 140, which is mounted on the second frame 112. The translation mechanism 140 includes a second drive member 141 and a slide table 142. The second drive member 141 is mounted on the second frame 112 and connected to the slide table 142. The slide table 142 slides along a first direction with the second frame 112. The impact mechanism 130 is mounted on the slide table 142. Specifically, the mounting plate 131 of the impact mechanism 130 is connected to the slide table 142. The second drive member 141 can drive the entire impact mechanism 130 to move along the first direction through the slide table 142 to adjust the relative position of the impact mechanism 130 and the linear vibrating screen 120, thereby adjusting the impact area of ​​the impact mechanism 130, which is convenient and quick.

[0045] Optionally, the powder stripping device 100 further includes a filter screen 150, a first discharge nozzle 160, and a second discharge nozzle 170. The first discharge nozzle 160 is connected to the end of the linear vibrating screen 120 and is used to discharge the current collector. The filter screen 150 is disposed between the first discharge nozzle 160 and the impact mechanism 130 and is connected to the second discharge nozzle 170. The filter screen 150 is used to filter out the battery powder and prevent the current collector from leaking out (the volume of the current collector is much larger than the volume of the battery powder). The second discharge nozzle 170 is used to discharge the battery powder.

[0046] Optionally, the powder stripping device 100 also includes a conveyor line 180. The conveyor line 180 is located between the pyrometallurgical device and the linear vibrating screen 120. The conveyor line 180 is used to transport the high-temperature sintered electrode sheets 200 output from the pyrometallurgical device to the beginning of the linear vibrating screen 120 to realize the feeding function, which is convenient and fast.

[0047] The powder stripping device 100, linear vibrating screen 120, and impact mechanism 130 provided in this embodiment are all mounted on a frame 110. The impact mechanism 130 is positioned above the linear vibrating screen 120. The linear vibrating screen 120 is used to convey the electrode sheets 200 along a first direction, and the impact mechanism 130 is used to impact the electrode sheets 200 on the linear vibrating screen 120 along a second direction, so that the electrode sheets 200 are separated into current collectors and battery powder. The linear vibrating screen 120 is also used to drive the current collectors and battery powder to discharge along the first direction, which is perpendicular to the second direction. Compared with the prior art, the powder stripping device 100 provided in this invention, due to the use of the linear vibrating screen 120 mounted on the frame 110 and the impact mechanism 130 positioned above the linear vibrating screen 120, can achieve complete stripping of battery powder from the surface of the current collector, enhance the separation effect, improve the battery powder recovery rate, and increase economic benefits. This results in high recycling efficiency and good recycling effect for lithium battery recycling equipment.
