Description

Technical Field

[0001] The utility model belongs to the technical field of electrolyte collection, and in particular relates to a semi-solid lithium battery electrolyte collection device. Background Art

[0002] Semi-solid batteries have electrodes made of a slurry of tiny lithium compound particles mixed with a liquid electrolyte. The battery uses two streams of slurry, one positively charged and one negatively charged. Both streams pass through aluminum and copper current collectors, with a water-permeable membrane between them. As the two streams pass through the membrane, lithium ions are exchanged, causing an electric current to flow on the outside. To recharge the battery, a voltage is simply applied to cause the ions to move back through the membrane.

[0003] The utility model patent with the authorization announcement number CN220671074U discloses a semi-solid lithium battery electrolyte collection device, including: a turntable connected to the transmission shaft of the motor; an electrolyte extraction box fixed on the turntable by a clamp, wherein the electrolyte extraction box includes: a shell abutting the turntable and the clamp; a flexible battery clamp fixed on the bottom surface of the shell; an electrolyte collection tank arranged on the edge of the bottom surface of the shell, and the shell surrounds the flexible battery clamp and the electrolyte collection tank. The semi-solid battery electrolyte can be fully extracted without pollution, and can be used for soft-pack or steel-shell batteries, with high application value.

[0004] However, the above mechanism needs to clamp and lock the battery when installing it, and continue to operate the clamp when removing the battery, which is cumbersome.

The bottom end of the battery positioning frame 9 is inclined in a direction away from the axis of the main shaft 7. The battery positioning frame 9 includes an outer frame body 91, and a filter cartridge 92 is connected to the inner side of the outer frame body 91. A filter bag 93 is inserted into the inner side of the filter cartridge 92. A plurality of cylindrical semi-solid batteries of different specifications can be inserted into the inner side of the adapted battery positioning frame 9 after the break, and the internal extract can be stably thrown out during the centrifugation process to achieve efficient and rapid Extraction, the battery positioning frame 9 is arranged at equal intervals around the axis of the main shaft 7. Multiple battery positioning frames 9 arranged around the main shaft 7 can make the main shaft 7 evenly stressed when rotating, thereby ensuring the stability of the main shaft 7. The outer frame 91 is welded by multiple annular tubes and rod structures parallel to the axis of the annular tubes. The outer frame 91 can provide stable support for the filter cartridge 92 and stably bear the force applied by the battery during the rotation of the battery. The filter cartridge 92 is a cylindrical structure with an open top. The filter cartridge 92 can be used to support the filter bag 93 to avoid The deformation of the filter bag 93 affects the filtering effect of the filter bag 93 on impurities in the battery. The main shaft 7 includes a shaft body 71, and a right prism 72 is formed at the bottom end of the shaft body 71. The top end of the driving shaft 5 is provided with a groove structure adapted to plug in the right prism 72. After the driving shaft 5 is plugged in and connected with the right prism 72, it can stably drive the main shaft 7 to rotate as a whole.

The cover plate 2 is firmly mounted on the lower shell 1 under the action of the plurality of bolts, so as to realize the stable rotation of the main shaft 7.

[0032] The working principle of this technical solution is as follows: After making a break at one end of the battery and pouring in the extraction liquid, when the electrolyte is fully dissolved in the extraction liquid, according to the size of the battery, place the broken end of the battery downward inside the battery positioning bracket 9 that fits it. After the battery is installed, install the cover plate 2 on the lower housing 1 so that the top end of the shaft body 71 is inserted into the rotating seat 21, and then use bolts to connect the lower housing 1 and the cover plate 2 to limit the axial position of the main shaft 7. Start the motor 3, and the motor 3 drives the drive shaft 5 to rotate through the belt drive mechanism 4. The rotating drive shaft 5 drives the main shaft 7 to rotate stably as a whole through the regular prism 72 inserted inside, so that the main shaft 7 drives the battery positioning bracket 9 to rotate at a high speed around the axis of the main shaft 7 through the connecting frame 8, thereby causing the extraction liquid in the battery installed in the battery positioning bracket 9 to be thrown out under the action of centrifugal force, pass through the pores of the filter bag 93 and the filter cylinder 92, and fall on the inner wall and bottom of the lower housing 1 for collection. The operator can release the collected extraction liquid after opening the drain valve 6.
