A method of using the agitated electroplating bath recovery apparatus of any of claims 1-8, wherein, The use method specifically comprises the following steps: Step one: through the operation of the control panel (8), the external liquid inlet pipe injects the electroplating solution into the second filter tank (9), the large-particle impurities in the electroplating solution are pre-filtered, and then the pre-filtered electroplating solution is injected into the recycling tank (7), when the amount of the electroplating solution reaches a threshold value, the external liquid inlet pipe is closed in time, the driving motor (1) is started, the rotating shaft (12) drives the stirring paddle to rotate in one direction, so that the vortex is generated in the electroplating solution, because the flow velocity is low, the pressure is high, and the particles with a density less than that of the liquid are easy to gather at the liquid surface in the vortex center; Step two: at this time, the extension end of the second cylinder (46) is the longest, the first piston (41) is located in the recycling tank (7), because the stirring paddle rotates in one direction, the particles with a density greater than that of the liquid are easy to gather at the center of the bottom inner wall of the recycling tank (7), and then enter the collecting pipe (42), the pump body is started, so that the absorption pipe (2) absorbs the particles with a density less than that of the liquid into the first filter tank (3), at this time, the second control valve is in a closed state, so that the particles with a density greater than that of the liquid are located on the top of the second piston (49); Step three: by controlling the extension end of the second cylinder (46) to contract to the shortest, the first piston (41) enters the collecting pipe (42), the second piston (49) slides down to the position corresponding to the input end of the distribution pipe (43) on the top, so that the solution carrying the particles on the top of the second piston (49) is discharged through the distribution pipe (43), the electromagnet plate (45) is started, the solution carrying the particles will flow downwards along the electromagnet plate (45), and the magnetic metal impurities are adsorbed on the electromagnet plate (45), wherein, because the electroplating solution in the collecting pipe (42) is discharged from the distribution pipe (43), the non-magnetic impurities attached to the electromagnet plate (45) are washed down. Step four: before the electromagnetic plate (45) is opened, the first cylinder (54) is at the shortest end, the baffle (53) is separated from the opening of the heat conduction dish (55), the remaining solution carrying particles will flow into the heat conduction dish (55), the electric heating plate (59) and the gas filtering tool (51) are opened, the solution in the heat conduction dish (55) is heated by the electric heating plate (59), the gas filtering tool (51) cooperates with the air inlet pipe (57) to absorb and filter the harmful gas generated in the heat conduction dish (55), and then the first cylinder (54) is controlled to extend to the longest, so that the baffle (53) covers the opening of the heat conduction dish (55), and at the same time, the electromagnetic plate (45) is closed, so that the magnetic metal impurities fall into the chute (52) and then enter the collection box (56); Step five: control the second cylinder (46) to extend to the longest and reset, at this time, the first piston (41) is located in the recovery tank (7), and the second piston (49) is located above the input end of the distribution pipe (43), the first control valve and the second control valve are opened in sequence, so that the electroplating solution filtered out of impurities is discharged along the liquid discharge pipe (47).
