[0014] In one possible design, multiple abutments are fixedly connected to the outer walls of both receiving frames. Two of the abutments are rotatably connected to limit blocks via a pivot.

[0016] In this application, the top of the equipment box has two inlets, and an inlet frame is fixedly installed on the inner wall of each inlet to guide and position the waste lithium batteries. The bottom of both inlet frames is fixedly connected to the feeding pipe, which guides the waste lithium batteries into the receiving frame inside the equipment box. The discharge is controlled by the opening and closing of a solenoid valve. When the receiving frame is full of waste lithium batteries, one of the electric push rods is activated, which pushes one of the sliding boxes to move. The sliding box moves one of the receiving frames through a connecting rod until it pushes the receiving frame to the top of the collection tank. When the sliding box moves, the guide block and the limit... The positioning block makes its movement more stable. At this time, the second motor is started. The second motor drives the two eccentric wheels to rotate, and through the transmission of the hinge rod and hinge block, it causes the steel needle to move up and down, piercing the waste lithium battery located in the receiving frame and draining the electrolyte. Before the steel needle pierces the battery residue, the decontamination plate first contacts the battery residue. The steel needle will pierce the battery residue through the decontamination hole of the decontamination plate. At this time, multiple springs on the decontamination plate will contract. When a small amount of battery residue is stuck on the steel needle, after the steel needle rises, multiple springs will push the decontamination plate to move and reset, so that the residue on the steel needle will be scraped off by the decontamination hole. The electrolyte passes through the filter at the bottom of the receiving frame. The electrolyte flows into the collection frame through the orifice. When pressure is applied to the waste lithium batteries inside the collection frame, it is supported by a lifting frame and lifting plate located at its bottom to prevent the collection frame from being damaged under strong pressure. At the same time, the electrolyte is discharged through the drainage holes of the lifting plate, so that its flow is not affected. In addition, multiple blocks can also abut against the top of the collection tank to further distribute the downward pressure on the collection frame. After the electrolyte in the collection frame is discharged, it is retracted again using an electric push rod. When it is at the top of the collection frame, the first motor is started. The first motor drives the drive shaft to rotate, causing the gear on the drive shaft to rotate. The rotation of the gear drives the gear meshing with it to rotate, so that the connection... The rod rotates, and the connecting rod drives the receiving frame to rotate. The other side of the receiving frame is rotatably connected to the limiting block, making its rotation more stable. After rotating 180 degrees, the waste battery residue inside is poured into the collection frame. At the same time, when the receiving frame is tilted, the other receiving frame can move to the top of the water tank to discharge the electrolyte. After the receiving frame that has finished emptying the waste battery residue returns to its original position, the solenoid valve of the feeding pipe on this side opens, and the waste battery residue with electrolyte to be discharged is discharged into its interior. When the discharge is complete, the electrolyte in the other receiving frame will also be discharged, so that they can work alternately, further improving the working efficiency of the device.

[0017] In this utility model, a solid-liquid separation device for recycling electrolyte from waste lithium batteries can achieve the effect of puncturing waste batteries to drain their internal electrolyte through a puncture mechanism, and there will be no residue adhering to the steel needle, thus further enhancing the practicality of the device.

[0018] In this utility model, a solid-liquid separation device for recycling waste lithium battery electrolyte can achieve the effect of alternating operation of the two receiving tanks of the device through a sliding mechanism, thereby enhancing the working efficiency of the device.

[0019] In this invention, the puncture mechanism removes battery residue adhering to the steel needle through its decontamination plate, making the device operate more stably. The sliding mechanism, through efficient automated processing and compact structural design, enables the device to work alternately and repeatedly, enhancing the device's working efficiency and improving the efficiency of the separation process.

A second synchronizing rod is fixedly connected to one side of each hinge block 18 that is close to the other. Sleeves are rotatably connected to the outer walls of both the first and second synchronizing rods. The two ends of the hinge rod 23 are fixedly connected to the outer walls of the two sleeves.

The tops of the multiple springs 21 are fixedly connected to the bottom of the fixed plate, and the bottoms of the multiple springs 21 are fixedly connected to the top of the cleaning plate 19.

Driven by the hinge rod 23 and the hinge block 18, the steel needle 20 moves up and down to pierce the waste lithium battery located in the receiving frame 11 and discharge the electrolyte. Before the steel needle 20 pierces the battery residue, the cleaning plate 19 first contacts the battery residue. The steel needle 20 will pierce the battery residue through the cleaning hole of the cleaning plate 19. At this time, the multiple springs 21 on the cleaning plate 19 contract. When a small amount of battery residue is stuck on the steel needle 20, after the steel needle 20 rises, the multiple springs 21 push the cleaning plate 19 to move and reset, so that the residue on the steel needle 20 is scraped off by the cleaning hole.

When full, one of the electric push rods 5 is activated, which pushes one of the sliding boxes 6 to move. The sliding box 6, through a connecting rod, moves one of the receiving frames 11 until it is pushed to the top of the water collection tank 14 to remove the electrolyte. As the sliding box 6 moves, the guide block and the limiting block make its movement more stable. After the electrolyte in the receiving frame 11 is discharged, the electric push rod 5 is used again to retract it. When it is at the top of the collection frame, the first motor 7 is activated. The first motor 7 drives the transmission shaft 8 to rotate, causing the gear 9 located on the transmission shaft 8 to rotate.

The connecting rod drives the receiving frame 11 to rotate, and the other side of the receiving frame 11 is rotatably connected to the limiting block, making its rotation more stable. After rotating it 180 degrees, the waste battery residue inside is poured into the collection frame. At the same time, when the receiving frame 11 is tilted, the other receiving frame 11 can move to the top of the water collection tank 14 to discharge the electrolyte. After the receiving frame 11 that has finished discharging the waste battery residue is reset, the solenoid valve of the feeding pipe 3 on this side is opened, and the waste battery residue to be discharged electrolyte is discharged into its interior. When the discharge is completed, the electrolyte in the other receiving frame 11 will also be discharged, so that they can work alternately, further enhancing the working efficiency of the device.
