AI Technical Summary
Existing shear-type aerators suffer from uneven water flow distribution and insufficient mixing, resulting in low overall aeration efficiency.
By installing a baffle plate and a shearing component on the rotating spindle inside the oxygenation chamber, air and water are mixed using shearing action. Combined with the design of the drive mechanism and bearings, the water flow path is guided and made uniform, avoiding short-circuiting and improving oxygen dissolution efficiency.
It significantly improves oxygen dissolution efficiency and the uniformity of water circulation, enhances the overall oxygenation effect, and reduces energy consumption.
