AI Technical Summary
Traditional horizontal screw centrifuges have low differential speed control precision, resulting in low dewatering efficiency or easy clogging when processing sludge with large fluctuations in viscosity and solids content.
The system employs a dual-motor drive system, which controls the speed difference between the rotating drum and the spiral blades by using a rotary motor and an auxiliary motor respectively. This allows for precise control of the sludge dewatering process, and combined with the pushing action of the spiral blades, it improves dewatering efficiency.
It achieves strong adaptability to different sludge properties, avoids clogging problems, and significantly improves sludge dewatering efficiency and continuity.
