Leak-Proof Vertical Reducer | CNC Formed Inverted Umbrella Impeller
The Inverted Umbrella Vertical Surface Aerator is a low-speed surface aeration equipment specifically engineered for industrial wastewater and municipal sewage treatment processes. Driven by a parallel vertical shaft reduction mechanism, it rotates a high-strength bottom inverted umbrella impeller to spirally lift sewage and sludge along the inverted cone.
The rising sewage carries the surrounding water and is forcefully thrown out from the impeller's edge, creating a hydraulic jump that engulfs massive amounts of air for highly efficient oxygenation. Simultaneously, the impeller's lifting and pushing action drives the water to circulate forward in a spiral pattern within the oxidation ditch, keeping the activated sludge mixture completely suspended.
Vertically adjustable, thick steel plates with square steel support for concentricity
Water Flow Speed
> 0.3 m/s (within oxidation ditch)
Key Applications
Oxidation Ditches & River Aeration: This machine is not only suitable for sewage aeration in activated sludge processes but also highly effective for ecological aeration in rivers and oxidation ponds. It performs exceptionally well in oxidation ditch processes, providing immense radial push-flow and oxygenation capabilities.
Multi-Industry Wastewater Treatment: Extensively deployed in the wastewater treatment operations of petroleum, chemical, tanning, pharmaceutical, papermaking, food, and gas industries, achieving large-area complete mixing and high-efficiency pollution control.
Core Features & Technical Solutions
Traditional horizontal aerators are prone to oil leaks at the shaft end. How does this vertical aerator solve this issue?
The equipment utilizes a dedicated vertical parallel shaft reducer, which features a highly compact and lightweight structure. Because of this vertical orientation, the reducer requires absolutely no horizontal seals, fundamentally eradicating the possibility of oil leakage at the input shaft end that plagues horizontal structures.
How is the equipment's durability and long-term operational stability guaranteed?
The system is heavily reinforced across multiple components. First, the main shaft is forged from high-strength, large-diameter 45# solid steel in a single process, guaranteeing perfect concentricity and a long service life. Second, to counteract the upward thrust generated by hydraulic reaction forces, a dedicated "lifting ring" is installed to protect the reducer from severe mechanical damage. Finally, the inverted umbrella impeller delivers formidable radial propulsion while remaining completely "clog-free and tangle-free," ensuring peak dynamic efficiency continuously.
