Product Description
Radial Flow Induction Inverted Umbrella Surface Aerator for Wastewater Basins
Vertical inverted umbrella surface aerators are widely utilized in municipal wastewater treatment and industrial sectors, including petroleum, chemical, tanning, pharmaceutical, papermaking, food processing, and coking. The equipment is highly effective for the Activated Sludge Process, as well as river restoration and oxidation pond aeration, with specialized performance in Oxidation Ditches. As a low-speed aeration solution, it excels in radial flow induction, high oxygen transfer rates, and intensive mixing capabilities.
Construction Features
- Main Shaft: Machined from single-piece high-strength 45# solid steel; ensures superior concentricity and durability.
- Gearbox: Heavy-duty vertical parallel-shaft type; optimized service factor for harsh environments and high-power stability.
- Adjustable Base: Heavy-gauge steel construction with precision-machined leveling; vertically adjustable with ≥300mm concrete anchoring.
- Dual-Axial Thrust Device: Isolates the gearbox from underwater axial loads and hydraulic upthrust, significantly extending service life.
- High-Torque Coupling: Precision-machined for wear-free operation under high torque; features a quick-disassembly design for easy maintenance.
- Inverted Umbrella Impeller: Optimized for flow dynamics and oxygen transfer; components are CNC waterjet-cut and formed in a single process.
Product Features
- Dedicated Vertical Gearbox: Utilizes a specialized vertical reducer, resulting in a compact footprint and reduced overall equipment weight.
- Zero Leakage Risk: The vertical configuration eliminates the need for horizontal seals, fundamentally eradicating the oil leakage issues commonly associated with the input shafts of horizontal gearboxes.
- High-Efficiency Impeller: The inverted umbrella impeller provides powerful radial thrust and a wide completely-mixed zone. It offers high power efficiency and is self-cleaning, preventing debris entanglement and clogging.
Working Principle
The unit consists of a vertical-shaft drive, adjustable base, dual-axial thrust device, high-strength coupling, and an inverted umbrella impeller. It operates by rotating the impeller to lift oxygen-deficient sludge along the conical surface, discharging it to create a hydraulic jump for rapid oxygenation. Simultaneously, it drives the mixture into a spiral circulation at a velocity of >0.3m/s, ensuring continuous liquid renewal and keeping activated sludge in full suspension.
