10m Depth Alloy Steel Sand Suction System - Eddy Current Submersible Pump

Siphon Sand Suction System - High-Efficiency Desanding Equipment with Eddy Current Submersible Pump

Product Overview

The Bridge-Type Siphon Sand Suction Machine is engineered for efficient grit removal in aeration grit tanks at sewage treatment plants. Combining a siphon-based suction mechanism with an eddy current submersible pump, this system ensures seamless extraction of sand and debris with minimal energy consumption. Its simple structure and automated operation make it ideal for municipal and industrial wastewater applications.

Working Principle & Structure

1. Automated Traversing:

   • The machine moves along rails installed over the grit settling tank, covering the entire tank width.

2. Siphon-Enhanced Suction:

   • A vortex submersible pump (eddy current design) extracts sand-water mixtures from the tank bottom.

   • Siphon action amplifies suction efficiency, reducing pump workload.

3. Integrated Skimming:

   • An optional skimmer blade removes surface scum, directing it to a slag trough.

4. Grit Separation:

   • Extracted混合物 is delivered to a gravel separator for dewatering and organic matter removal.

Technical Parameters

Key Features

1. Dual-Function Design: Simultaneous sand suction and surface skimming in a single pass.

2. Eddy Current Submersible Pump:

   • Low-lift, high-efficiency operation without water diversion.

   • Clog-resistant and wear-resistant for long-term reliability.

3. Aerated Grit Cleaning: Circulates grit to remove organic matter, eliminating odors.

4. Automated Control: Local or remote operation with programmable logic controllers (PLC).

5. Low Maintenance: Simple structure with minimal moving parts reduces downtime.

6. Adaptability: Customizable tank dimensions (width, depth, length) to fit existing infrastructure.

Applications

• Municipal Sewage Plants: Aeration grit tanks in urban wastewater treatment facilities.

• Industrial Wastewater: Pre-treatment for food processing, textiles, and chemical plants.

• Water Intake Systems: Sand removal in river or reservoir water purification plants.

Why Choose This System?

• Energy Efficiency: Eddy current pump technology cuts power consumption by up to 30%.

• Odor-Free Output: Aerated washing ensures discharged grit is environmentally safe.

• Quick Installation: Pre-assembled components and rail-based design simplify setup.

• Compliance Ready: Meets ISO 9001 and GB standards for wastewater equipment.

Customization Options

• Tank dimensions (width, depth, length).

• Pump capacity (20–30 m³/h).

• Control systems (manual, semi-automatic, full PLC automation).

• Material upgrades (stainless steel, corrosion-resistant coatings).
