The alkali adding component 4 includes a medicine tank 30 fixed to the top outer wall of the shell 2, and the bottom of the medicine tank 30 is welded with a medicine discharge pipe 31 connected to the inside of the medicine tank 30, and the medicine discharge pipe 31 is connected to the shell 2. The top outer wall of the shell 2 is fixed with a third electric push rod 33 by bolts, and one end of the telescopic part of the third electric push rod 33 is fixed to the limit plate 32 by bolts. The limiting plate 32 is inserted into the medicine dispensing pipe 31 and fits against the inner wall of the medicine dispensing pipe 31, and the third electric push rod 33 is started to contract, and the third electric push rod 33 will pull the limiting plate 32 to move outside the medicine dispensing pipe 31. At this time, the alkali liquid in the medicine tank 30 will be added into the housing 2 through the medicine dispensing pipe 31. The control component is the controller body 1, and the controller body 1 includes a control module 34, a data processing module 35, an electrical module mounting plate 36, a data analysis module 37 and a communication module 38. The data analysis module 37 is electrically connected to the alkali liquid concentration detector 7 and the photoelectric switch body 5, and the data analysis module 37 is connected to the data processing module 35. The data processing module 35 is connected to the control module 34. The control module 34 It is electrically connected to the first electric push rod 15, the second electric push rod 18 and the third electric push rod 33, and the communication module 38 is connected to the external device. It is connected to the local area network through the communication module 38 in the controller body 1. The alkali concentration detector 7 will pass the detected data to the data analysis module 37.

[0035] Working principle of this embodiment: when in use, the communication module 38 in the controller body 1 is connected to the local area network, and the alkali solution concentration detector 7 will detect the concentration of the alkali solution in real time, and the alkali solution concentration detector 7 will transmit the detected data to the data analysis module 37, the data analysis module 37 analyzes the concentration of the alkali solution and transmits the analysis result to the data processing module 35, the data processing module 35 will process the detected data and display it on the mobile phone, when the staff observes that the concentration of the alkali solution is low, the control module 34 will control the first electric push rod 15 to extend, the first electric push rod 15 will drive the moving plate 16 to move along the slide groove 17, and the moving plate 16 will drive the rack 1 23 and the rack 2 29 to move, At this time, since rack 1 23 is meshed with half toothed disc 22 and rack 29 is not meshed with full toothed disc 21, rack 1 23 will drive half toothed disc 22 to rotate, and half toothed disc 22 will drive connecting shaft 8 to rotate, and connecting shaft 8 will drive spoiler frame 19 to rotate and cause first torsion spring 9 to generate torque. When half toothed disc 22 rotates to disengage from rack 1 23, connecting shaft 8 will reverse through the force of first torsion spring 9, so that half toothed disc 22 will mesh with rack 1 23 again, and the cycle will continue, so that spoiler frame 19 will swing. Since the lithium battery is located at the bottom of shell 2, the concentration of alkali solution at the bottom will decrease rapidly during the alkalization process of the lithium battery, while the concentration of alkali solution at the top will not decrease because it does not contact the lithium battery. The alkali solution above and below is stirred and mixed by the swing of the spoiler frame 19, thereby increasing the concentration of the alkali solution below, making full use of the alkali solution, avoiding waste of alkali solution and saving costs. After the alkali solution above and below is stirred and mixed to alkalize the lithium battery and the concentration of the alkali solution is reduced again, the control module 34 will first discharge the alkali solution in the outer shell 2, and then start the third electric push rod 33 to contract. The third electric push rod 33 will pull the limit plate 32 to move out of the lower medicine pipe 31. At this time, the alkali solution in the medicine tank 30 will be added to the outer shell 2 through the lower medicine pipe 31, thereby increasing the concentration of the alkali solution and improving the subsequent alkalization efficiency of the lithium battery. When it is necessary to clean the impurities in the alkali solution, the second electric push rod 18 is started to extend. The rod 18 will push the second slide 27 to move upward, and the second slide 27 will drive the rack 29 to move upward and mesh with the full toothed disc 21. At the same time, the second slide 27 will mesh with the second tooth groove 28 through the transmission toothed disc 24, which will cause the transmission toothed disc 24 to rotate when the second slide 27 moves upward. During the rotation process, the transmission toothed disc 24 will mesh with the first tooth groove 26 to move the first slide 25 downward. The first slide 25 will drive the rack 1 23 to move downward, so that the rack 1 23 is disengaged from the half toothed disc 22, and then the first electric push rod 15 is started to extend. At this time, the meshing of the rack 29 and the full toothed disc 21 will cause the full toothed disc 21 to rotate, and the full toothed disc 21 will drive the rotating drum 13 to rotate, and the rotating drum 13 will drive the filter screen 20 to rotate.The filter screen 20 is used to filter and screen out impurities in the alkali solution. When the filter screen 20 rotates to the other side of the partition plate 10, the impurities on the filter screen 20 will fall into the collection box 11, so that the collection box 11 collects the impurities uniformly. During the rotation of the filter screen 20, the spoiler frame 19 will be driven to rotate synchronously, and the spoiler frame 19 will drive the connecting shaft 8 to rotate. When the impurities on the filter screen 20 fall into the collection box 11, the full toothed disc 21 is disengaged from the rack 29 and the rack 1 23 is engaged with the half toothed disc 22. At this time, the rotating cylinder 13 will be reversed by the force of the second torsion spring 14 to drive the filter screen 20 to reset, and the connecting shaft 8 will be reversed by the force of the first torsion spring 9 to drive the spoiler frame 19 to reset. At the same time, the communication module 38 is connected to the local area network for control to achieve remote control, thereby improving the intelligence and automation of the recycling mechanism. When the lithium battery is discharged into the housing 2 through the feeding pipe 3, the photoelectric switch body 5 will be blocked. At this time, the photoelectric switch body 5 will detect that the lithium battery is being discharged. ,
