[0035] Working principle: when the oil removal operation of electroplated parts before plating is carried out, the operator first opens the sealing cover 13 movably connected at the top of the treatment tank 1, and then places the electroplated parts to be treated on the electroplated part tray 52. The electroplated part tray 52 is tightly fitted in the filter hole groove 50 of the filter cartridge 5 by means of the tray hook 51, and the filter cartridge 5 is firmly clamped on the rotating disc holder 4. Then, the circulating pump 22 and the driving motor 3 are started. The driving motor 3 drives the rotating disc holder 4 to rotate smoothly on the sealing shaft seat 15, and since the filter cartridge 5 is clamped and connected with the rotating disc holder 4, the filter cartridge 5 and the electroplated parts carried therein rotate synchronously. At the same time, the circulating pump 22 starts to work, draws the cleaning agent from the cleaning agent tank 21, and then delivers it to the spray pipe 23 in the treatment tank 1 through the pump pipe. The cleaning agent is uniformly sprayed from the spray pipe 23 and covers the rotating electroplated parts. Then, the valve on the liquid inlet pipe 11 is opened, and the external clean water flows into the treatment tank 1 after being effectively filtered by the filter, mixes with the cleaning agent to form a cleaning solution, and preliminarily cleans the electroplated parts. The operator can check the cleaning status in real time through the observation window 10 provided on the treatment tank 1. When the cleaning solution reaches the appropriate liquid level, the ultrasonic generator 25 and the heating coil 6 are started. The ultrasonic generator 25 generates high-frequency electric signals, which are transmitted to the ultrasonic transducers 24 uniformly distributed on the inner wall of the treatment tank 1 through a line. The ultrasonic transducers 24 convert the electric signals into mechanical vibrations, and generate strong ultrasonic waves in the cleaning solution, which use the cavitation effect to remove stubborn dirt on the surface of the electroplated parts. The heating coil 6 heats the cleaning solution, and the temperature of the cleaning solution is monitored in real time by the temperature controller 7 installed on the side wall of the L-shaped supporting arm 14, which communicates with external equipment through a line, feeds back the power of the heating coil 6, and adjusts the power to ensure that the cleaning solution maintains the optimal cleaning temperature, thereby further enhancing the cleaning effect. After the oil removal operation is completed, the circulating pump 22, the ultrasonic generator 25 and the heating coil 6 are sequentially turned off. The valve on the liquid outlet pipe 12 is opened, and the sewage containing dirt and impurities is discharged from the treatment tank 1 after being filtered again by the filter on the liquid outlet pipe 12. Since the bottom of the treatment tank 1 is designed as a reverse funnel structure, the impurities will be concentrated at the bottom under the action of liquid flow, which is convenient for subsequent cleaning.
