Fully Automatic Sludge Dewatering Equipment for Petrochemical Plants & Food Factories
Product Overview
The Volute Sludge Dewatering Machine (TPDL) represents an advanced screw press technology designed for efficient sludge treatment in petrochemical plants and food processing facilities. This innovative system features a clog-free design that eliminates the need for sedimentation and sludge thickening tanks, significantly reducing construction costs for wastewater treatment plants. Utilizing a unique combination of rotating screws and moving rings for self-cleaning, the TPDL operates under full PLC automation control. With its low-speed operation, this cutting-edge equipment consumes minimal power and water compared to traditional centrifuges, belt presses, and frame filter presses.
Working Principle
Wastewater is fed into the dewatering machine where sludge is conveyed toward the discharge outlet by helical blades. As the gap between these blades progressively narrows, the sludge undergoes increasing pressure, initiating the dewatering process. The separated water is expelled through spaces between fixed and moving plates, while the dewatered sludge is discharged as cake.
Key Advantages
Clog-Free Design: Self-cleaning mechanism prevents blockages
Cost Efficiency: Reduces infrastructure requirements and operational costs
Automated Operation: PLC-controlled for continuous, unmanned performance
Low Energy Consumption: Slow screw speed minimizes power usage
Versatile Application: Suitable for both petrochemical and food processing industries
Minimal Water Usage: Superior efficiency compared to centrifugal systems
