when the cylinder output shaft stretches, the cylinder output shaft drives the connecting rod to reciprocate through the fixing ring, the stirring blades on the connecting rod stir the original solution in the discharge tank and the newly introduced solution, the position of the waste battery is changed, the newly introduced solution is quickly blended into the original solution and reacts with the waste battery, and the waste battery is discharged.
2. The discharging device for recycling lithium batteries as recited in claim 1, wherein the bracket is an "L" shaped bracket, the cylinder is installed at the top of the horizontal section of the bracket, and one end of the vertical section of the bracket is fixedly connected with the bottom of the storage bin by a bolt.
3. The discharging device for recycling lithium batteries according to claim 2, wherein the outer ring of each baffle is slidably connected with a sliding sleeve which is matched with the baffle and is fixedly connected with the side wall of the storage tube.
4. The discharging device for recycling lithium batteries according to claim 1, wherein a floating plate is horizontally arranged inside the storage bin, a transverse plate is horizontally arranged on the top of the storage bin, and two sides of the bottom of the transverse plate are provided with support rods which penetrate through the top of the storage bin through sliding sleeves and are connected with the top of the floating plate.
5. The discharging device for recycling lithium batteries according to claim 1, wherein a contact switch is installed at the top of the storage bin and at the bottom of the transverse plate, a feeding pump is installed at one side of the top of the discharging groove, the discharging end of the feeding pump is communicated with the top feeding hole of the storage bin through a pipe body, and the output end of the contact switch is electrically connected with the input end of the feeding pump.
6. The discharging device for recycling lithium batteries as recited in claim 4, wherein the floating plate is provided with supporting plates at both sides of the bottom thereof.
7. The discharging device for recycling lithium batteries as recited in claim 1, wherein the two sides of the bottom of the storage bin are respectively provided with a bottom frame detachably connected with the top of the base.
8. The discharging device for recycling lithium batteries according to claim 1, wherein the control unit is used for controlling the movement of the cylinder and processing the information fed back by the gas detection unit.
