[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. When lithium batteries are scrapped after a long period of use, they can be recycled. When recycling used lithium batteries, they need to be crushed to avoid polluting the environment with used lithium batteries.

[0024] Example

[0026] ② The second aspect is to only set up a static screen structure to realize the screening of the crushed waste lithium batteries. The crushed waste lithium battery fragments are easy to accumulate on the screen surface, which greatly reduces the efficiency of sorting and recycling;

[0027] To do this, see Figure 1-3 The utility model provides a waste lithium battery efficient sorting and recycling device, comprising: a crushing box 1, a feed hopper 2 is fixed at the top feed port of the crushing box 1, two symmetrically arranged transmission shafts 22 are arranged below the feed hopper 2 and are rotatably connected to the inside of the crushing box 1, and crushing rollers 21 are fixedly connected to the outsides of the two transmission shafts 22, one end of one of the transmission shafts 22 extends to the outside of the crushing box 1 and is connected to the output shaft of the motor 23, the motor 23 is fixedly connected to the outside of the crushing box 1, and the other ends of the two transmission shafts 22 extend to the outside of the crushing box 1 and are fixedly connected to the gear 24, the two transmission shafts 22 are fixedly connected to the outside of the crushing box 1, and the two transmission shafts 22 are fixedly connected to the outside of the crushing box 1. The gears 24 are meshed with each other, a discharging square tube 3 is installed at the bottom discharging port of the crushing box 1, and a supporting frame 11 is also fixedly connected to the bottom end of the crushing box 1. A receiving box 4 is placed on the inner bottom wall of the supporting frame 11, and a sorting frame 5 movable at the bottom of the discharging square tube 3 is arranged above the receiving box 4. A screening net 51 is fixedly connected to the inner wall of the sorting frame 5, and the bottom end of the screening net 51 is flush with the bottom end of the sorting frame 5. Guide seats 52 with an I-shaped structure in a vertical section are slidably connected in the guide grooves provided on the two side walls of the supporting frame 11, and a disassembly structure 6 is connected between the two guide seats 52 and the sorting frame 5;

[0028] It also includes a reciprocating transmission structure 7, which is installed on one of the gears 24 and connected to the guide seat 52 on the same side. The reciprocating transmission structure 7 can realize the back and forth reciprocating movement of the sorting frame 5 synchronously while the gear 24 is operating.

[0029] Further as Figure 1-3 As shown, it is worth explaining in detail that, in order to facilitate the disassembly and cleaning of the sorting frame 5 from the two guide seats 52, a disassembly and assembly structure 6 is provided, including an insertion strip 61 fixedly connected to the opposite ends of the two guide seats 52, and the vertical section of the insertion strip 61 is an isosceles trapezoidal structure. Insertion channels 62 matching the insertion strip 61 are provided on the two side walls of the sorting frame 5, and a moving track 65 is fixedly connected to the front side wall of the sorting frame 5. Two symmetrically arranged moving seats 64 slide in the moving channel provided on the front side wall of the moving track 65. The vertical section of the moving seat 64 is a convex structure. A spring 66 is connected between the opposite ends of the two moving seats 64. The ends of the two moving seats 64 that are away from each other are fixedly connected to an insertion rod 63, and the other ends of the insertion rod 63 are movably inserted into the insertion hole provided on the outer wall of the insertion strip 61. Push columns 67 are fixedly connected to the outer surfaces of the two moving seats 64.

[0030] The jack is attached Figure 3 It can be seen that the outer wall of the insert 61 is arranged near the front.

[0031] Further as Figure 1-3 As shown, it is worth explaining in detail that in order to be able to synchronously link the sorting frame 5 to move back and forth when the two crushing rollers 21 crush the battery material, a reciprocating transmission structure 7 is set up, including a transmission column 71 fixed at the edge of the surface of the gear 24, and an L-shaped transmission rod 72 is movably sleeved on the outer side of the transmission column 71.

The transmission channel 73 is L-shaped and has a width equal to the diameter of the transmission column 71.

[0032] The width of the transmission channel 73 is equal to the diameter of the transmission column 71 in order to prevent the L-shaped transmission rod 72 from moving outside the transmission column 71 .

[0033] In summary: when using the efficient waste lithium battery sorting and recycling equipment, first, the prepared waste lithium battery material is inverted into the feed hopper 2, and by starting the motor 23 and cooperating with the action of the two gears 24, the two crushing rollers 21 rotate in opposite directions, and the waste batteries can be crushed, and the crushed battery fragments are discharged from the discharge square tube 3 to the sorting frame 5 below. In addition, the gear 24 drives the transmission column 71 to rotate, and the transmission column 71 drives the guide seat 52 connected to the L-shaped transmission rod 72 to move back and forth, so that the sorting frame 5 connected to the two insertion strips 61 can be at the bottom of the discharge square tube 3 at the same time to move back and forth, thereby greatly improving the sorting work efficiency, and can also effectively prevent the crushed battery particles from clogging the screening net 51.
