(2) when a plated part is sequentially placed in each cleaning tank 3, the PLC 40 controls a hydraulic rod on the fork shearing frame 601 to work, so that the fork shearing frame 601 is driven to extend, two oppositely arranged spray buckle discs 60 are close to the plated part, the PLC 40 controls the high-pressure water pump 61 to pump an external water source into the spray buckle discs 60 through a connecting pipe and spray the external water source to the surface of the plated part through 10 atomizing nozzles 600, plating solution on the surface of the plated part is further cleaned, after the cleaning is finished, the PLC 40 controls the hydraulic machine 6010 to work, so that the fork shearing frame 601 is driven to compress, the two oppositely arranged spray buckle discs 60 are far away from the plated part, and then the plated part is taken out;
(3) the conductivity in the first and last recovery tanks 2 is measured by using the conductivity meter 30, when the conductivity meter 30 detects that the increase amplitude of the conductivity in the first cleaning tank 3 is too fast, the PLC 40 can automatically increase the spraying water amount of the spraying device 6 in the recovery tank 2 and the blowing air amount of the high-pressure blowing-off device 21, when the conductivity meter 30 detects that the conductivity concentration in the last cleaning tank 3 exceeds 100us/cm, the cleaning liquid in the first cleaning tank 3 is discharged, then the cleaning liquid in the second cleaning tank 3 is pumped into the first cleaning tank 3 by the liquid pumping pump 7, the cleaning liquid in the third cleaning tank 3 is pumped into the second cleaning tank 3 by the liquid pumping pump 7, and then pure water is injected into the third cleaning tank 3;
(4) the cleaning liquid subjected to the three-stage counter-current rinsing is collected in the recovery tank 2, and as the cleaning liquid passes through the concentration evaporator 20, firstly, the cleaning solution enters a weak electrolysis box body 200, weak electrolysis treatment is carried out on the cleaning solution by using a weak electrolysis loop between an anode plate 2011 and a cathode plate 2012, impurities in the cleaning solution are removed, then enters the concentration tank 203 after passing through the heat exchanger 202, and after the cleaning solution enters the concentration tank 203, enters the innermost sub-case 2030 first, and is diffused to the outside through the water passage holes 2032 formed in the side wall of the innermost sub-case 2030, then sequentially passes through the inside and the outside of each sub-box 2030, the PLC 40 controls the heating ring 2033 to start, the cleaning liquid in each sub-tank 2030 is heated, the steam generated after heating enters the concentration tank 203 again for heating, when the conductivity of the cleaning solution in the concentration tank 203 is the same as the desired concentration of the plating solution, the plating solution is discharged into the plating tank 1 for reuse.
