Description

Technical Field

[0001] This utility model relates to the field of impeller aeration technology, specifically a variable frequency synchronous impeller aerator. Background Technology

[0002] The variable frequency synchronous impeller aerator is a high-efficiency oxygenation device used in aquaculture. It mainly consists of a variable frequency permanent magnet synchronous motor, an adaptive variable frequency controller, a nylon gearbox, a shell-shaped tooth or web-claw impeller, a 304 stainless steel support rod, and a high-strength special float. Its working principle is to refresh the upper and lower interfaces of the water flow through mechanical movement, disperse the water into fine droplets and spray them into the air, increasing the contact area between air and water. At the same time, due to negative pressure, the gas is drawn in and turned into bubbles, which are then pressed into the water, thereby increasing the oxygen content in the water.

[0003] Existing variable frequency synchronous impeller aerators are widely used. However, during use, the impellers of these aerators are frequently exposed to water and sunlight, leading to rapid damage and frequent replacements. Furthermore, the existing impellers are not easy to disassemble, resulting in slow disassembly speeds for workers and impacting work efficiency.

[0004] Therefore, a variable frequency synchronous impeller aerator is proposed to address the above problems. Utility Model Content
