Stainless Steel Sand Suction Machine - 4m Suction Type Reciprocating Pump

Bridge-Type Desanding Equipment: 4m Sand Suction & Skimming System

Company Overview

Located in Yixing, Jiangsu Province, China, Longdai Co., Ltd is a specialized supplier of petrochemical and environmental processing equipment. We integrate independent R&D, design, general contracting, manufacturing, and material supply to deliver tailored solutions for industrial water and wastewater treatment.

Key Parameters

Main Features

1. Efficient Reciprocating Operation: Combines sand suction and slag skimming in a simple, high-efficiency structure.

2. Vortex Submersible Pump: No water diversion required; resistant to clogging and wear for safe, reliable performance.

3. Unidirectional Skimming: Ensures thorough cleaning of pool surfaces.

4. Aerated Grit Circulation: Removes organic matter from sand, eliminating odor in discharged grit.

5. Dual Control Modes: Local or remote operation for user convenience.

Applications

Primarily used for sand-water treatment in aeration grit tanks at urban sewage treatment plants or water plants. It extracts settled sand, cinder, and other large particles from the tank bottom and discharges them into a sand collection tank. Optional oil/slag skimming attachments are available for customized needs.

Structure & Working Principle

The equipment features a mobile bridge design with a pump suction system. Key operational steps:

1. Sand Suction: At rest, the machine stations at the water inlet. Upon activation, it traverses the tank while a submersible pump extracts sand and grit via a suction pipe.

2. Skimming: A scraper blade skims surface scum into a skimmer tank at the pool end.

3. Reciprocating Motion: Reverse movement lifts the skimmer rake to prevent backflow, ensuring continuous sand discharge and skimming.

4. Grit Processing: Extracted grit flows to a sand-water separator for further treatment.

Why Choose Our System?

• Customizable Design: Adapts to pool dimensions (width, depth, length) and user requirements.

• Durable Construction: Corrosion-resistant materials and robust mechanical components.

• Low Maintenance: Wear-resistant pumps and automated controls reduce operational costs.

• Turnkey Solutions: From design to material supply, we provide end-to-end support.
