Technical Field

[0001] The utility model relates to the technical field of battery electrolyte recovery, in particular to a battery electrolyte recovery device. Background Art

[0002] Batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and a non-aqueous electrolyte solution. Due to the extremely active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. Therefore, lithium batteries need to be recycled after use.

[0003] When recycling lithium batteries, the electrolyte is generally made of high-purity organic solvents, electrolyte lithium salts, necessary additives and other raw materials, prepared in a certain proportion under certain conditions. It has certain hazards. If accidentally inhaled, it will cause headaches, dizziness, weakness, nausea, difficulty breathing, etc., so it is necessary to recycle the electrolyte in the used lithium batteries. At present, the common recycling method for lithium battery electrolyte is to crush the used lithium batteries through a crusher, and then use filtering equipment to filter out the electrolyte. However, this method is relatively cumbersome, and because the crushing effect of the crusher is relatively thorough, the recycled electrolyte is prone to fine fragments, and there is a problem of unclean filtration, resulting in poor quality of the recycled electrolyte.

Two cone nails and two extrusion plates are respectively fixedly mounted on the bottom surfaces of the supporting plates. The extrusion plates have the effect of squeezing the batteries, and the cone nails have the effect of puncturing the batteries.

[0008] Preferably, a stabilizing device is provided on the inner bottom surface of the processing box. The stabilizing device includes a long groove, which is formed on the inner bottom surface of the processing box. Two vertical strips are slidably connected to the interior of the long groove. The ends of the vertical strips away from the long groove are fixedly connected to the placement box. The provision of the vertical strips has the effect of supporting the placement box.

[0012] 1. In the utility model, by providing an auxiliary device, when it is necessary to recover the electrolyte of the battery, the battery is first placed inside the placement slot, and then the motor is started. The motor starts to drive the threaded rod to rotate, and the rotation of the threaded rod drives the T-shaped plate to move downward inside the vertical slot. The T-shaped plate moves downward inside the vertical slot, driving the connecting rod to move downward. The downward movement of the connecting rod drives the carrying plate to move downward. The downward movement of the carrying plate drives the cone nail and the extrusion plate to move downward. The cone nail will first pierce the middle of the battery, so that a large amount of electrolyte flows into the interior of the filter box through the through slot and is filtered through the filter screen and collected inside the filter box. As the carrying plate continues to press downward, the extrusion plate will squeeze the two ends of the battery, so that the remaining electrolyte of the battery can be gathered into the through hole pierced in the middle of the battery, thereby ensuring the recovery effect of the electrolyte. Through the cooperation of the above structure, the crusher is avoided from being used for highly crushing processing. Not only can other components be relatively completely retained and recovered, but also the problem of highly crushed debris mixing with the electrolyte affecting the recovery quality can be avoided, and the use effect is good.
