The invention relates to a pretreatment type lithium battery separation and recovery method

Lithium battery is mainly by acting as a partition of the film, positive and negative electrode powder, electrolyte, shell composition, attached to the black powder above the positive electrode for the diaphragm, the negative electrode above the graphite, graphite and the powder above the positive electrode collectively referred to as black powder; Lithium batteries need to be broken and recycled after exceeding their service life; The main recovery is: black powder, copper and aluminum, electrolyte and metal shell. The invention relates to a pretreatment type lithium battery separation and recovery method;

First of all, we need to pre-discharge the lithium battery to prevent fire when broken.

Then, the chemical discharge is used to ensure that the discharge is complete, and the lithium battery is dried after pre-discharge. Next is the rough breaking process, the lithium battery is placed in the rough breaking machine, and then into the second rough breaking machine, in this process, the electrolyte volatilization, the broken material into the low temperature evaporation equipment.

Then the crushing and separation process is carried out, the broken lithium battery is placed on the vibrating screen, the diaphragm and black powder are sucked away by the cyclone separator, and the tail gas is blown into the pulse dust collector for treatment. At the same time, the copper foil and aluminum foil fall to the magnetic separation conveyor conveying the next broken. The second vibrating screen screens the small particles to achieve material separation and small size film, copper and aluminum separation. Followed by the magnetic screening process, the magnet will be the material on the iron, nickel and other magnetic impurities suck away.

Lithium battery recycling equipment A pretreatment type lithium battery separation and recycling method, using multiple crushing multiple physical step separation of materials, to achieve the effect of completely separating the film, copper aluminum foil and black powder, to avoid harm to the human body, reduce environmental pollution, save resources.
