Description

Technical Field

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloys as positive and negative electrode materials and a non-aqueous electrolyte solution. Lithium metal batteries were first proposed and researched in 1912, and research on lithium-ion batteries began in the 1970s. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use place high demands on the environment. With the advancement of science and technology, lithium batteries have become mainstream.

[0003] In the prior art, such as the Chinese patent number CN214262221U, a screening device for lithium battery recycling includes a bottom plate, a bracket fixedly connected to the top outer wall of the bottom plate, a screening assembly fixedly connected to the outer wall of one side of the bracket, and a crushing assembly fixedly connected to the top outer wall of the screening assembly; the crushing assembly includes a middle frame and an upper frame, and the inner wall of the middle frame is rotatably connected to a roller assembly, the number of roller assemblies is two groups, and the roller assembly includes two coaxially arranged turntables. The utility model is provided with a crushing assembly, wherein the batteries enter the roller assembly area along the guide frame, the crushing motor is started, driving the turntable to rotate, and the cutting plate crushes the batteries. For batteries with smooth surfaces that are retained in the guide frame, a grab hook is inserted into the surface to tear the surface and accelerate the crushing. At the same time, when the battery crushing becomes stuck, the cutting motor is simultaneously started. Due to the stagnation of the turntable, the core shaft can continue to work and crush the battery, which can timely resolve the blockage inside the crushing assembly.

[0004] Although the above scheme has the advantages as mentioned above, the disadvantage of the above scheme is that the traditional screening devices for lithium battery recycling only screen the fragments after crushing, and do not screen the different specifications of lithium batteries to be recycled. Since the internal electrolyte components of lithium batteries of different specifications may be different, resulting in different recycling standards, it is impossible to screen lithium batteries of different specifications, which is not convenient for later recycling and reduces the recycling efficiency of lithium batteries. In addition, when replacing screens of different specifications, it is impossible to quickly replace screens of different specifications, which reduces the practicality of the screening device for lithium battery recycling.

One side of the inner wall of the swing rod 110 is movably connected to one side of the other slider 106. A collecting plate 111 is fixedly connected to the top of one of the sliders 106, and a sealing door 115 is connected to one side of the outer surface of the collecting plate 111 through a hinge.

[0032] In this embodiment, the device is first placed in the desired position as a whole, and the lithium batteries to be classified are poured into the hollow plate 113. The screening screen 2 that meets the specifications has been replaced in the hollow plate 113. Then, the external power supply of the servo motor 108 is turned on, and the servo motor 108 is started by the controller. The output end of the servo motor 108 starts to drive the rotating rod 109 to rotate in a circle. As the rotating rod 109 rotates in a circle, the swing rod 110 also swings back and forth up and down, and gradually drives the two sliders 106 to move left and right in the square groove 103 respectively. The two sliders 106 then perform relative reciprocating motion and are reset by the return spring 110. 04 and the reset spring 2 105 reset the slider 106.

[0035] Working principle: When in use, first place the entire device in the desired position, and pour the lithium batteries to be classified into the hollow plate 113. The screening screen 2 that meets the specifications has been replaced in the hollow plate 113. Then turn on the external power supply of the servo motor 108, and use the controller to start the servo motor 108. The output end of the servo motor 108 begins to drive the rotating rod 109 to rotate in a circle. As the rotating rod 109 rotates in a circle, the swing rod 110 also swings back and forth up and down, and gradually drives the two sliders 106 to move left and right in the square groove 103 respectively. The two sliders 106 now perform relative reciprocating motion, and the slider 106 is reset by the return spring 104 and the return spring 2 105. At the same time, when the other slider 106 moves left and right, the extension plate 112 at the top of the other slider 106 begins to gradually drive the hollow plate 113 to move back and forth left and right. The lithium batteries to be screened begin to be gradually screened into the collection plate 111 through the holes of the screening mesh plate 2, and the lithium batteries of the required specifications are quickly screened out. Then the servo motor 108 is turned off, the sealing door 115 is opened, and the screened lithium batteries are manually taken out, so that lithium batteries of different specifications can be screened, which is convenient for later recycling and improves the recycling efficiency of lithium batteries. In order to facilitate the rapid replacement of the screening mesh plate 2, the staff first pulls out multiple pins 202 at the same time, quickly takes out the original screening mesh plate 2, and then puts the screening mesh plate 2 of the new specification into the hollow plate 113, and then loosens the multiple pins 202. The multiple pins 202 are quickly pushed out by the elastic force of the spring body 203, and the multiple pins 202 are quickly inserted into the holes in the hollow plate 113 and the screening mesh plate 2, thereby completing the quick disassembly operation of the screening mesh plate 2, thereby achieving the rapid replacement of screens of different specifications and improving the practicality of the screening device for lithium battery recycling.
