[0040] When the present invention is in use, firstly, the installation of the discharge hopper 203 is conducive to guiding the batteries to be crushed onto the two rollers 201, and the operation of the driving motor 202 makes the two rollers 201 rotate synchronously in opposite directions, which is conducive to extruding and crushing the batteries, and the installation of the discharge plate 204 is convenient for placing the batteries to be crushed in advance, and by pushing the push handle 208, the push handle 208 drives the push rod 206 to slide under the action of the return spring 207, which is conducive to driving the push plate 205 to push the batteries on the discharge plate 204 into the discharge hopper 203, so as to safely carry out the loading work and prevent the batteries from popping out and causing harm. After pushing the batteries, the push handle 208 is reset under the action of the return spring 207, and drives the push plate 205 to reset, so as to ensure the safety of the battery loading. The second guide plate 303 is installed to facilitate the subsequent battery placement and pushing, and the broken batteries are conveniently connected to the screen 302 through the installation.

The second deceleration bar 306 is installed on the screen 302, which is conducive to slowing down the speed of debris sliding down, thereby improving the screening effect. The first collection box 401 and the second collection box 403 are conducive to storing the debris guided down by the first guide plate 301 and the third guide plate 304, and the handle 402 is used to lower the debris.

After the classified and collected debris is transported, a certain proportion of sulfuric acid and an appropriate amount of carbon powder are added before reduction roasting. Sulfuric acid is used to reduce the activation energy between the reduction of nickel cobalt manganese oxide and lithium, and the ability of carbon powder reduction is improved. At the same time, due to the action of sulfuric acid, the reduction reaction is changed from "solid-solid reaction" to "liquid-solid reaction". ", increases the contact area between the reactants, which can not only improve the degree of reduction reaction, but also improve the reaction rate. The calcined material is then immersed in water, and the lithium oxide produced by the reduction reacts with water to form lithium hydroxide, which is then dissolved in the aqueous solution, thereby achieving the purpose of separation from nickel, cobalt and manganese. By controlling the proportion of sulfuric acid and carbon powder added, the reduction temperature and the reduction time, the reduction rate of the ternary waste can reach up to 92%, which means that the water leaching rate of lithium can reach 92%, which can fully realize the "fast in and fast out" of lithium in the ternary waste. The installation of the connecting pipe 503 and the external vacuum cleaner is conducive to exhausting the inside of the two fixed shells 502. Under the connection of the rotating sleeve 505, the dust suction groove 506 on the rotating block 501 is connected to the inside of the fixed shell 502.The dust suction groove 506 can thereby perform suction and dust suction work. When the debris flows through the first guide plate 301, the generated dust powder can be sucked away by the dust suction groove 506, and the broken paper pieces can be sucked away and recycled at the same time. Since the suction force is constant, the debris will not be sucked out. At the same time, the rotation of the rotating block 501 is conducive to adjusting the suction angle, so that it is convenient to suck out debris in different directions according to needs. When the roller 201 rotates, the eccentric driving groove 605 repeatedly resists the connecting sleeve 604, so that the two transmission rods 601 make reciprocating motion, which is conducive to the shaking of the second guide plate 303, so that the debris can be discharged smoothly. Under the action of the two connecting rods 603, the shaking of the second guide plate 303 drives the shaking of the first guide plate 301, which is conducive to the smooth discharge of the first guide plate 301 without blockage, and improves In order to improve the quality of screening, the installation of multiple baffles 703 and multiple fixed plates 702 is conducive to shielding the bottom of the lower hopper 203. Under the action of the driving shaft 707, the multiple baffles 703 can rotate, which is conducive to the opening and closing of the baffles 703 and the fixed plate 702. When the second guide plate 303 shakes, under the action of the movable groove 708 and the movable rod 709, the two pull rods 701 can shake, thereby realizing the driving control of the driving rod 706. The two driving rods 706 resist and pull the two control rods 704, so that the control rods 704 drive the multiple swing rods 705 to swing, so that the multiple baffles 703 can rotate and open and close, which is conducive to the batteries inside the lower hopper 203 being poured into the roller 201 in turn for crushing, and the batteries will not pop out under the action of the baffles 703, which plays a protective role.
