China Grit-Water Separator: Shaftless Screw Style Desanding Equipment for Grit Basin in Urban Sewage Treatment
Introduction
The spiral sand-water separator is designed for grit tanks in sewage treatment plants. It is an integrated system for separating and lifting inorganic grit from sewage, capable of effectively removing particles with a diameter ≥0.2mm. With high separation efficiency, this equipment features a shaftless spiral design and operates without water bearings. Its lightweight, compact structure, reliable performance, and easy installation make it an ideal solution for sand-water separation.
Applications
The LSF sand-water separator is suitable for grit removal in grit tanks of urban sewage treatment plants. It is commonly paired with cyclone grit degreasing tanks or bridge-type sand suction machines to enhance the separation of sand-water mixtures.
Technical Parameters
Key Features
-
Efficient Drive System: Equipped with a shaft-mounted parallel shaft helical gear reducer, ensuring compact design, stable operation, and high safety.
-
High Recovery Rate: Achieves a recovery rate of ≥96% for particles larger than 0.2mm.
-
Wear-Resistant Lining: The U-shaped groove features a replaceable inner lining with excellent wear resistance and long service life.
-
Fully Enclosed Design: Provides a clean operating environment and eliminates the need for embedded parts. The frame is securely fixed using expansion bolts.
-
Flexible Control: Can be integrated with auxiliary equipment for centralized control or operated independently with a local control box.
Structure and Working Principle
The equipment utilizes a shaftless spiral mechanism. The sand-water mixture is fed into the top of the separator, where grit settles by gravity in the separation tank. The shaftless spiral rotates at a 25° angle, gradually conveying the grit along the U-shaped groove to the discharge outlet, where it falls into a collection container for removal. The separated water is discharged through the overflow weir, ensuring improved operational efficiency and convenient transport of dewatered grit.
