DETAILED DESCRIPTION

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Figure 1 A first structural schematic diagram of a pressure discharge device for waste lithium batteries according to an embodiment of the present invention is shown. The pressure discharge device includes a frame 100, a discharge bottom frame 200 fixedly mounted on the frame 100, a discharge movable frame 300 movably mounted within the discharge bottom frame 200, and a pressure plate 400 movably mounted within the discharge movable frame 300. The top and one side of the discharge bottom frame 200 are open, while the upper and lower ends of the discharge movable frame 300 are through-connected. The frame 100 is further provided with a first power device 500 and a second power device 600. The discharge movable frame 300 is driven by the first power device 500 to move vertically within the discharge bottom frame 200, and the pressure plate 400 is driven by the second power device 600 to move vertically within the discharge movable frame 300. When the pressure discharge device is in operation, the discharge bottom frame 200 seals the bottom of the discharge movable frame 300, and the pressure plate 400 seals the top of the discharge movable frame 300, forming a discharge space.

[0028] When using the pressure discharge device for waste lithium batteries of the present invention, the first power device 500 can be used to drive the discharge movable frame 300 to move vertically downward until it contacts the discharge bottom frame 200, so that the bottom of the discharge movable frame 300 is closed by the discharge bottom frame 200. At this time, conductive particles and waste lithium batteries can be placed into the discharge movable frame 300 from the top; then, the second power device 600 is used to drive the pressure plate 400 to move vertically downward to the top of the closed discharge movable frame 300; then, the pressure plate 400 is continued to be driven vertically downward for a certain distance to provide discharge space. The conductive particles and the waste lithium batteries in the discharge box are uniformly, stably and strongly pressured, so that the conductive particles and the waste lithium batteries are in full and close contact for discharge. After the waste lithium batteries are discharged, the second power device 600 is first used to drive the pressure plate 400 to move vertically upward until it leaves the discharge movable frame 300, and then the first power device 500 is used to drive the discharge movable frame 300 to move vertically upward for a certain distance, so that the conductive particles and the waste lithium batteries are released from the discharge movable frame 300. The whole process does not require the lifting of heavy objects, is convenient and fast, and the effect of applying pressure is good, which is conducive to improving the discharge efficiency of the waste lithium batteries.

[0029] In addition, in the pressure discharge device for waste lithium batteries of the present invention, the discharge space can actually be used for squeezing and crushing the waste lithium batteries. The pressure plate 400 cooperates with the second power device 600 to provide strong pressure, and the discharge movable frame 300 can effectively prevent battery fragments and the like from splashing, thereby expanding the use of the pressure discharge device.

[0030] In some specific implementations, the outer periphery of the discharge movable frame 300 is consistent with the inner periphery of the discharge bottom frame 200 , which is beneficial to enhancing the working stability of the discharge movable frame 300 .

[0031] In some specific implementations, see Figure 1 The first power unit 500 is fixedly mounted on top of the frame 100 and includes at least one first hydraulic cylinder. The output end of the first hydraulic cylinder is fixedly connected to the discharge movable frame 300 via a first connecting rod 510. The first hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation, and can easily drive the discharge movable frame 300 to move vertically within the discharge bottom frame 200.

[0032] For details, please refer to Figure 1 The discharge movable frame 300 is fixedly connected to at least two auxiliary rods 310. The auxiliary rods 310 and the first connecting rods 510 are parallel to each other. The auxiliary rods 310 are movably arranged in the frame 100. The auxiliary rods 310 can effectively improve the stability of the vertical movement of the discharge movable frame 300, which is conducive to reducing the workload of the first connecting rods 510.

[0033] In some specific implementations, see Figure 1 The second power unit 600 is fixedly mounted on top of the frame 100 and includes at least one second hydraulic cylinder, the output end of which is fixedly connected to the pressure plate 400 via a second connecting rod 610. The second hydraulic cylinder is also a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation, easily driving the pressure plate 400 to move vertically within the discharge movable frame 300 and providing sufficient pressure for the conductive particles and used lithium batteries. The second hydraulic cylinder can also provide pressure to crush the used lithium batteries.

[0034] Figure 2 A second structural diagram of the pressure discharge device for waste lithium batteries in an embodiment of the present invention is shown. The open side of the discharge bottom frame 200 is hinged with a discharge channel 700, which facilitates people to clean out the waste lithium batteries and conductive particles from the discharge bottom frame 200.

[0035] For details, please refer to Figure 2 The discharge channel 700 is provided with a vibrator 710. A first rubber cushion 720 is provided between the discharge channel 700 and the discharge bottom frame 200, and a second rubber cushion is provided between the bottom surface of the discharge channel 700 and the frame 100. The vibrator 710 vibrates the discharge channel 700, thereby automatically discharging the waste lithium batteries and conductive particles from the discharge channel 700. The first rubber cushion 720 prevents hard contact between the discharge channel 700 and the discharge bottom frame 200, while the second rubber cushion prevents hard contact between the discharge channel 700 and the frame 100. This improves the vibration efficiency of the discharge channel 700 and reduces vibration noise.

[0036] For further information, see Figure 2 A discharge port 730 is provided on the side of the discharge channel 700 away from the discharge bottom frame 200. A discharge hopper 740 is connected to the bottom surface of the discharge channel 700. A screen 750 connects the discharge channel 700 and the discharge hopper 740. Conductive particles can pass through the screen 750 and be discharged from the discharge hopper 740, while used lithium batteries cannot pass through the screen 750 and be discharged from the discharge port 730, thus achieving automatic separation of the conductive particles and used lithium batteries. The screen 750 forms a downwardly concave arc-shaped pit, which increases the residence time of the conductive particles within the pit and helps ensure sufficient separation of the conductive particles and used lithium batteries.

[0037] A third buffer rubber pad is provided between the discharge hopper 740 and the frame 100 to support the discharge hopper 740 while reducing noise.

[0038] Figure 3 A schematic diagram of the structure of the discharge movable frame and stripper plate in an embodiment of the present invention is shown. A stripper plate 320 is provided at the bottom of the discharge movable frame 300. One side of the stripper plate 320 is pivotally connected to one side of the bottom of the discharge movable frame 300, while the other side of the stripper plate 320 extends from the open side of the discharge bottom frame 200. When the pressure discharge device is in operation, the discharge bottom frame 200 and the stripper plate 320 abut against each other, sealing the bottom of the discharge movable frame 300. When the first power unit 500 drives the discharge movable frame 300 vertically upward, the side of the stripper plate 320 pivotally connected to the discharge movable frame 300 is lifted by the discharge movable frame 300, while the side of the stripper plate 320 extending from the open side of the discharge bottom frame 200 remains in place, forming an inclined slope. This allows the conductive particles and used lithium batteries to slide down automatically, accelerating the discharge process.

[0039] Figure 4 Shown Figure 3 In the structural diagram of area A, a rotating shaft groove 321 and an arc block 322 are provided on one side of the stripper plate 320, and a rotating shaft block 301 and an arc groove 302 are provided on one side of the bottom of the discharge movable frame 300. The rotating shaft groove 321 and the rotating shaft block 301 are rotatably matched, and the arc block 322 and the arc groove 302 are rotatably matched, so that the stripper plate 320 and the discharge movable frame 300 form a stable rotational connection, and the rotational connection will not interfere with the discharge bottom frame 200.

[0040] For further information, see Figure 4 The arc block 322 is provided with a first limiting portion 3221, and the arc groove 302 is provided with a second limiting portion 3021. The second limiting portion 3021 blocks the rotation path of the first limiting portion 3221. The first limiting portion 3221 and the second limiting portion 3021 cooperate with each other to limit the maximum opening angle between the stripper plate 320 and the discharge movable frame 300, preventing the stripper plate 320 from rotating too much, and ensuring that the conductive particles and used lithium batteries slide smoothly out of the discharge bottom frame 200. Preferably, the maximum opening angle between the stripper plate 320 and the discharge movable frame 300 does not exceed 25°.

[0041] The working process of the pressure discharge device for waste lithium batteries of the utility model is as follows:

[0042] First, the first hydraulic cylinder is activated to drive the discharge movable frame 300 to move vertically downward. When the stripper plate 320 contacts the discharge bottom frame 200, as the discharge movable frame 300 continues to move vertically downward, the stripper plate 320 gradually closes until the stripper plate 320 seals the bottom of the discharge movable frame 300. At this time, conductive particles and used lithium batteries can be placed into the discharge movable frame 300 from the top.

[0043] Then, the second hydraulic cylinder is activated to drive the pressure plate 400 to move vertically downward to the top of the closed discharge movable frame 300; then, the pressure plate 400 is further driven to move vertically downward for a certain distance, applying uniform, stable and strong pressure to the conductive particles and waste lithium batteries in the discharge space, so that the conductive particles and waste lithium batteries are in full and close contact to discharge;

[0044] After the waste lithium batteries are discharged, the second hydraulic cylinder is activated to drive the pressure plate 400 to move vertically upward until it leaves the discharge movable frame 300. Then, the first hydraulic cylinder is activated to drive the discharge movable frame 300 to move vertically upward. The side of the discharge plate 320 that is rotatably connected to the discharge movable frame 300 is driven up by the discharge movable frame 300, and the side of the discharge plate 320 that extends from the open side of the discharge bottom frame 200 remains in place, thereby forming an inclined slope, allowing the conductive particles and waste lithium batteries to automatically slide into the discharge channel 700.

[0045] The vibrator 710 is started to vibrate the discharge channel 700, so that the waste lithium batteries and conductive particles are automatically discharged from the discharge channel 700; after being screened by the screen 750, the conductive particles are discharged from the discharge hopper 740 and the waste lithium batteries are discharged from the discharge port 730, completing the separation of the conductive particles and the waste lithium batteries.

[0046] The pressure-discharging device for waste lithium batteries of the present invention eliminates the need for heavy lifting, making the entire process quick and convenient. Furthermore, the pressure application is effective, thereby improving the discharge efficiency of waste lithium batteries. Automatic unloading, discharge, and separation are achieved through the unloading plate 320, discharge channel 700, vibrator 710, and screen 750, making it more convenient to use. Furthermore, the pressure-discharging device for waste lithium batteries of the present invention has a simple structure and is easy to maintain. Furthermore, the pressure-discharging device for waste lithium batteries of the present invention can also be used to crush waste lithium batteries, thus providing a wide range of applications.
