摘要： The subject of the invention is the device for disposal of lithium batteries that are not suitable for further use. The device for disposal of lithium batteries, where the ground batteries are immersed in tanks with water/acid converting the base - electrolyte lithium salts and metals into chlorides or other acid salts, and where the plastic is removed from the metal solution tank, rinsed and dried and then heated to the melting point of the plastic. The molten plastic is transported for further use and the metal solution is chemically treated to recover the pure metal. In the device for disposal of lithium batteries, under the hopper (1), there is a mill (14) where the batteries are thrown, cut and crushed into fine particles. The ground particles are picked up by the belt conveyor (2) and from it they are dropped into an openwork basket (6) suspended on the ropes (5) of winches (4) and placed in the acid tank (17). Next to the water/ acid tank (17) there is a tub (12) with the flushing liquid. The metals are dissolved in acid and after that the basket (6) is pulled up, then it is moved over the tub (12) and lowered there on the ropes (5). The residue is rinsed and then the basket (6) lifts again from the tub (12), the ground plastic particles are dried in the air stream of the conduit (8). The dried particles are discharged onto the conveyor belt (16), and from there to the screw conveyor (15). The screw conveyor (15) is heated to the temperature at which the plastic melts, the charge is compacted there and fed to the final processing station where the press (10) extrudes paving slabs or other functional shapes.
