Description

Lithium battery recovery equipment Technical Field The invention relates to the technical field of lithium battery recovery, in particular to lithium battery recovery equipment. Background In the recovery treatment process of the lithium battery, safe and thorough discharge of the lithium battery is an important pretreatment step. At present, a common discharging method is to soak the battery in a conductive discharging liquid. However, the existing soaking equipment mostly has the problems that firstly, a discharging tank is usually required to be manually loaded, immersed down, lifted and unloaded, the whole process is low in efficiency, operators have electric shock risks and poor in safety, secondly, a large amount of discharging liquid is required to be poured in order to ensure that the battery can be completely immersed, the liquid utilization rate is low, the cost is high, the overflow risk exists, and furthermore, the discharging efficiency is easily influenced by the electrolyte in the soaking process due to impurity accumulation, and the equipment lacks effective self-cleaning capability. Therefore, development of a lithium battery recycling and discharging device capable of realizing automatic continuous operation, saving the discharge liquid consumption and improving the safety and the cleanliness is needed. Disclosure of Invention Aiming at the defects of the prior art, the invention provides lithium battery recycling equipment, which solves the problems. The lithium battery recycling device comprises a soaking box and a top plate fixed at the top of the soaking box, wherein the inner cavity of the soaking box is respectively and slidably connected with two battery placing frames, and the top of each battery placing frame is fixedly connected with an upper frame; the surface of the top plate is provided with a lifting mechanism for lifting the battery placing rack; The lifting mechanism comprises a fixed wheel fixed on the surface of the top plate, the surface of the fixed wheel is in transmission connection with a pull rope, and two ends of the pull rope are respectively and fixedly connected with the tops of the two upper frames; The inner cavity of the soaking box is filled with discharge liquid, and when the battery placing rack is lowered to the lowest point, the battery above the battery placing rack is soaked in the discharge liquid; The inner chamber of soaking case is provided with the push pedal through cylinder drive fore-and-aft movement, the fixed surface of push pedal is connected with the spacing with battery rack bottom plate joint, the spacing is provided with two, and just be located the opening side and be located the intermediate position with the highest position and the intermediate position one by one of battery rack respectively, place the battery in the left battery rack when using, the battery rack of left side descends into the soaking incasement and soaks, descend to the minimum back, stretch out through the push pedal this moment, the spacing of bottom stretches out the joint battery rack and fixes a position it, then add the battery on the battery rack of right side, wait for the left side battery rack to discharge the back, withdraw the spacing, under the effect of gravity, the stay cord slides on the tight pulley, drive two battery racks and reach same level, two battery racks are located the intermediate position just at this moment, stretch out through the spacing to the left battery rack this moment, prevent its up-down motion, then carry out unloading to the battery that finishes discharging in the left side battery rack, after unloading, the automatic falling of battery rack, the automatic falling can receive the spacing, can position by the self-lifting and self-lifting of the self-elevating mechanism of the automatic positioning of the battery rack.
