The HKD pickling passivation drying line is used to improve the surface quality of the rear bridge for cathodic electrophoresis. The pickling line is an independent production line located in front of the electrophoresis line. The entire pickling, passivation, and drying line is automatically completed by 4 gantry single arm machines, with a total of 11 workstations, including 2 soaking degreasing cleaning tanks, 1 soaking acid washing slag cleaning tank, 4 soaking rinsing tanks, 1 soaking neutralization tank, 1 soaking passivation tank, and 2 hot air drying tanks. After effective degreasing cleaning, rinsing, passivation, and drying, it meets the cleaning requirements. The cleaning process utilizes the chemical degreasing and degreasing ability of the cleaning agent, The chemical reaction with chemical reagents achieves the effect of slag removal and passivation, making the surface of the workpiece meet the cleaning requirements.

This equipment has the characteristics of beautiful appearance, stable performance, reasonable structure, high production efficiency, good cleaning effect, and convenient use, making it an ideal cleaning equipment.

The cleaning machine mainly consists of a cleaning tank, a rinsing tank, a PP acid washing tank, a filtration and circulation storage system, a liquid level and temperature control system, an oil-water separation system, a hot air drying system, an automatic cover plate system, an in and out turnover material car, an in and out material level, a gantry single arm lateral movement system, an exhaust system, an electrical control system, etc.
