Residual liquid recovery equipment before cleaning of lithium battery solution finished product tank

The invention belongs to the technical field of lithium batteries, and particularly relates to a lithium battery solution finished product tank residual liquid recovery device before cleaning, the lithium battery solution finished product tank residual liquid recovery device comprises a chain conveyor belt, a placing rack and a finished product tank placed on the placing rack, and one side of the chain conveyor belt is fixedly provided with an L-shaped support. According to the residual liquid recycling equipment before cleaning of the lithium battery solution finished product tank, by arranging the pulling and retracting mechanism, a liquid suction pipe can be automatically positioned and dragged to enter the finished product tank, the traditional mode that a pipeline is manually held by hand to recycle residual liquid is replaced, rotation of an output shaft of a driving motor drives a rotating shaft to rotate, and rotation of the rotating shaft drives a connecting gear connected with the rotating shaft in
