ZQXN Peripheral Drive Full-bridge Suction Scraper

1. Working Principle

The ZQXN suction scraper operates by rotating the full-bridge structure around the tank center using a peripheral drive system. Suction pipes beneath the bridge utilize vacuum or hydraulic pressure to extract sludge from the tank bottom, which is then discharged through sludge outlets. An optional scum skimmer clears floating debris from the water surface, further enhancing the cleaning process.

2. Structural Features

• Peripheral Drive System: A motor and gearbox provide stable and powerful operation, suitable for long-term continuous use.

• Full-Bridge Structure: The bridge spans the entire tank diameter, offering robust support for the suction and drive systems.

• Suction System: High-efficiency suction pipes, available with vacuum or hydraulic operation, effectively remove sludge.

• Scum Skimmer (Optional): Designed to eliminate floating debris and maintain surface cleanliness.

• Corrosion-Resistant Materials: Constructed from stainless steel or carbon steel with anti-corrosion coatings for durability in harsh environments.

• Automated Control System: Includes options for automated start/stop functions, operational monitoring, and fault alarms.

3. Applications

• Municipal Wastewater Treatment: Suitable for sludge removal in primary and secondary sedimentation tanks.

• Industrial Effluent Treatment: Used in industries such as petrochemicals, food processing, and pharmaceuticals.

• Water Supply Purification: Applied in sedimentation tanks for efficient sludge removal in water treatment plants.

• Environmental Projects: Ideal for sedimentation processes requiring high-efficiency sludge suction and discharge.

4. Advantages

• Efficient Sludge Removal: Multi-point suction design ensures thorough and uniform sludge extraction, minimizing residual sludge.

• Stable Performance: The peripheral drive mechanism ensures smooth operation, even in large-diameter sedimentation tanks.

• Energy Efficiency: Low power consumption reduces operational costs and enhances sustainability.

• Easy Installation and Maintenance: Optimized full-bridge structure design simplifies installation and maintenance.

• Durability and Longevity: Made from high-quality materials, the equipment offers a long service life and excellent reliability.

5. Precautions

• Installation and Alignment: Ensure proper alignment of the drive system with the tank perimeter and secure leveling of the full-bridge structure.

• Routine Maintenance: Regularly inspect suction pipes, drive mechanisms, and the scum skimmer for wear or damage.

• Prevent Blockages: Keep sludge outlets and suction pipes clear to maintain efficiency.

• Safe Operation: Restrict unauthorized access during operation and disconnect power during maintenance.

• Customized Adaptation: Select the appropriate suction method (vacuum or hydraulic) based on the sedimentation tank's specific conditions.
