Water washing and liquid injection control system for recycling waste batteries

The invention relates to the technical field of washing liquid injection control, in particular to a washing liquid injection control system for waste battery recycling. The system comprises an analysis and comparison unit, an inspection and judgment unit, a calculation unit and a control and adjustment unit, and the control and adjustment unit controls and adjusts washing injection according to the calculated washing injection concentration data. According to the invention, the analysis and comparison unit obtains the recovered waste battery and the historical processing rate data of the waste battery, cleans the dirt on the surface of the waste battery, and analyzes the nickel oxide on the surface of the cleaned waste battery; the nickel oxide content in the analyzed nickel oxide data is compared with the set marked nickel oxide content when the nickel oxide content exceeds the standard, the condition of an oxide layer on the surface of the waste battery can be judged by comparing the nickel oxide content,
