Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figures 1-4 As shown, a waste lithium battery electrolyte removal device includes a housing 101, a support leg 103 connected to the housing 101, a baffle 102 for blocking electrolyte on the housing 101, a lithium battery puncture structure on the housing 101, an electrolyte extrusion component on the lithium battery puncture structure, and an electrolyte discharge structure on the housing 101.

[0030] In this embodiment, the lithium battery puncture structure first punctures the waste lithium battery placed in the box 101, and the electrolyte extrusion component squeezes the punctured lithium battery to accelerate the outflow of electrolyte, reduce the amount of electrolyte residue inside the lithium battery, and improve the removal effect of electrolyte from the waste lithium battery.

[0031] In one embodiment, such as Figure 1 As shown, the lithium battery puncture structure includes a movable plate 202 slidably disposed within a housing 101. A plurality of puncture rods 204 are connected to the lower surface of the movable plate 202. The plurality of puncture rods 204 are evenly distributed on the movable plate 202. The housing 101 is provided with a lifting assembly that drives the movable plate 202 to move up and down. The lifting assembly includes a first telescopic rod 203 connected to the housing 101. The output end of the first telescopic rod 203 is connected to the upper surface of the movable plate 202. When the first telescopic rod 203 extends, it drives the movable plate 202 to descend, so that the puncture rods 204 on the movable plate 202 approach the bottom plate of the housing 101 and puncture the waste lithium batteries placed on the bottom plate of the housing 101.

[0032] In one embodiment, such as Figure 2 and Figure 3 As shown, the box body 101 is symmetrically provided with sliding grooves 201. The movable plate 202 is slidably disposed in the box body 101. The sliding grooves 201 guide the movable plate 202 and improve the stability of the movable plate 202 when it moves.

[0033] In one embodiment, such as Figure 1 As shown, the electrolyte extrusion assembly includes an extrusion plate 205 slidably disposed on the puncture rod 204. A compression drive module is provided on the moving plate 202 to drive the extrusion plate 205 to slide on the puncture rod 204. The compression drive module includes two second telescopic rods 206 symmetrically connected to the moving plate 202. The output end of the second telescopic rods 206 is connected to the extrusion plate 205. A square hole 107 is provided on the top of the housing 101 corresponding to the position of the second telescopic rods 206. The extension of the second telescopic rods 206 drives the extrusion plate 205 to move closer to the bottom plate of the housing 101, thereby compressing the waste lithium batteries placed on the bottom plate of the housing 101.

[0034] In one embodiment, such as Figure 3 and Figure 4 As shown, the electrolyte discharge structure includes a drain port 104 located at the bottom of the housing 101. An electrolyte receiving assembly is provided on the support leg 103 at a position corresponding to the drain port 104. The electrolyte receiving assembly includes a receiving hopper 105 slidably mounted on the support leg 103. The bottom of the receiving hopper 105 is connected to a first outlet pipe 106. A filter assembly is provided on the housing 101 at the drain port 104. The filter assembly includes a slot 401 mounted on the housing 101. A filter screen 402 is slidably mounted in the slot 401. The upper surface of the receiving hopper 105 is in contact with the lower surface of the housing 101. The filter screen 402 filters the electrolyte flowing out from the waste lithium battery, effectively reducing the amount of solid insoluble matter in the electrolyte flowing out through the first outlet pipe 106, facilitating the subsequent reuse of the electrolyte. The filter screen 402 can be easily removed, and the receiving hopper 105 can be easily moved away for cleaning.

[0035] In one embodiment, such as Figure 3 and Figure 4 As shown, the liquid receiving hopper 105 is provided with a handle 108, and the filter screen 402 is provided with a rectangular hole 403, which facilitates the removal of the liquid receiving hopper 105 and the filter screen 402.

[0036] In one embodiment, such as Figure 1 and Figure 2 As shown, a vent 301 is provided on the housing 101. An electrolyte vapor condensation and recovery module 302 is provided on the outside of the housing 101 corresponding to the vent 301. The electrolyte vapor condensation and recovery module 302 extracts the gas inside the housing 101 through the vent 301 and condenses the extracted gas to recover the electrolyte that has evaporated into the air. The condensed and recovered electrolyte is discharged through a second liquid outlet pipe 303 provided on the electrolyte vapor condensation and recovery module 302.

[0037] The above embodiment discloses a waste lithium battery electrolyte removal device, wherein the first telescopic rod 203 first extends to drive the moving plate 202 to descend, so that the piercing rod 204 on the moving plate 202 approaches the bottom plate of the box 101 and pierces the waste lithium battery placed on the bottom plate of the box 101. Then, the second telescopic rod 206 extends to drive the squeezing plate 205 to approach the bottom plate of the box 101 and squeeze the waste lithium battery placed on the bottom plate of the box 101, thereby accelerating the electrolyte outflow speed, reducing the amount of electrolyte residue inside the lithium battery, and improving the removal effect of waste lithium battery electrolyte.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
