Ldl Series Spiral Mud Dehydrator
Loren Continuous Multiple Screw Dewatering Machine Definition
It's a New Type Clog-Free Solid-Liquid Separation Equipment By Utilizing Strong Screw Extrusion Pressure Between Screw Diameter And Pitch Change Under Tiny Gap Between Moving Rings And Fixing Rings To Realize Separation Or Sludge Dewatering Under Full Auto Control Plc Control Panel With Its Auto Self-Cleaning System.
It Can Replace Traditional Filter Press Like Belt Press Filter , Frame Plate Press, Volute Decanters In Some Special Field And Condition Sites.
Multiple Disc Ring Spiral Dewatering Machine Feature & Merit
-Lower Run Cost: 40% of Belt Press & 20% of Volute Decanter
-Energy Saving: Less Than 5% of Centrifuge Decanter
-Low Speed Run with No Vibration and Noise
-Little Water Consumption: 0.1% of Belt Filter Press
-Chemical Saving: Around 60%
-Compact Design: Save Site Room
-Investment Saving: 60%
-Clog-Free Performance: Fit for Sludge with oil, Grease and Fiber Perfectly
-No Filter Cloth , No Need High Pressure Back Washing
-PLC Control with More Accurate Performance and Convenience
-Applied in Many Raw Sludge Moisture Range: 95%-99%
-Concentrated Sludge Moisture Adjustable Range: 90%-96%
-High Thickening Efficiency
-Enclosure Working with No Secondary Odor or VOCS Generated
-Little Easy-Damaged Parts, Little Maintenance Fee
-Stainless Steel Module Structure Make It Run In A Long Life Time
The Multiple Disc Spiral Sludge Filter Press Working Principle
The Wastewater Is Pushed Into The Spiral Dehydrator,The Sludge Will Bear Heavier Pressure Of The Helical Aixs Blades And Began To Carry On Dewatering After Continuously Being Moved To The Outlet Port Of The Sludge Cake Due To The Gap Among The Helical Blades Gradually Becoming Narrower And The Water Will Then Comes Out From The Gap Between Fixed Plates And Moving Plates.
