WNG Suspended Central Drive Scraper

1. Working Principle

The scraper operates by rotating a drive unit located at the center of the tank. The scraper arms move slowly along the bottom of the tank, with the attached blades pushing the settled sludge toward the sludge outlet at the center of the tank. The suspended structure design reduces the equipment weight and enhances operational stability and efficiency.

2. Structural Features

• Central Drive System: The drive unit, consisting of a motor and gearbox, provides stable and reliable rotational power for smooth operation.

• Suspended Structure: The lightweight design allows for easy installation and reduces the load on the tank.

• Scraper Mechanism: The scraper blades are designed to efficiently collect the settled sludge and push it toward the discharge point.

• Corrosion-Resistant Materials: The equipment is made of stainless steel or carbon steel with anti-corrosion coatings, making it suitable for harsh wastewater environments.

• Automated Control: The system supports automated start/stop functions and real-time monitoring, reducing manual intervention.

3. Applications

• Municipal Wastewater Treatment: Ideal for use in thickening tanks and sedimentation tanks in wastewater treatment plants.

• Industrial Effluent Treatment: Widely used in food, pharmaceutical, chemical, and other industries for sludge removal in thickening tanks.

• Sludge Thickening: Perfect for sludge thickening tanks to efficiently collect and remove bottom sludge, improving concentration efficiency.

4. Advantages

• Efficient Sludge Collection: Adjustable scraper speed ensures high sludge collection efficiency, reducing the amount of sludge left behind.

• Stable Operation: The central drive design provides smooth operation with minimal downtime and low failure rates.

• Energy-Efficient: The low power consumption design reduces operational costs while meeting environmental standards.

• Easy Installation and Maintenance: The suspended structure simplifies installation, and the device is easy to maintain with low operational costs.

• Long Service Life: Made from durable, corrosion-resistant materials and high-quality components, the scraper has a long service life and low maintenance needs.

5. Precautions

• Proper Installation: Ensure the central drive unit is aligned with the tank center and that the suspended structure is securely mounted.

• Regular Maintenance: Inspect the scraper blades, drive system, and suspension components regularly and replace worn-out parts promptly.

• Operational Monitoring: Adjust the scraper speed based on the sludge concentration and water quality to optimize the operation.

• Prevent Blockages: Periodically clean the sludge discharge outlet to prevent clogging and ensure smooth operation.

• Safety Measures: Do not allow non-operators near the equipment during operation, and ensure the power is turned off during maintenance.
