Submersible Actuator Mixing for Low-Pressure Polymer Activation

The patent combines the motor and mixing mechanism into a single integrated submersible blending unit that is placed directly inside the reaction chamber. This merging eliminates the need for separate external motor mounting structures and complex water pressure transmission systems, while ensuring consistent blending performance even at low inlet pressures (as low as 5 PSI) because the blending action is driven by the submersible motor rather than by inlet water pressure.

The patent replaces static mixing devices that rely on high water pressure to create turbulence and mixing with an active mechanical submersible blending unit. This unit uses a motor-driven impeller or mixing mechanism that actively stirs and blends the polymer solution, thereby achieving high-quality mixing at very low inlet pressures (5-10 PSI) where static mixers would fail to generate sufficient flow and mixing action.

The submersible blending unit is designed to operate autonomously at low inlet pressures by using its own motor power to drive the mixing action. The system does not require high inlet water pressure to force mixing, as the blending is self-driven by the submersible motor. This self-service capability allows operation at inlet pressures as low as 5-10 PSI, significantly reducing energy consumption and equipment wear compared to systems requiring 30-60 PSI inlet pressure to achieve the same blending quality.

The patent replaces pressure-dependent passive mixing with an active submersible blending unit that provides consistent mixing performance independent of inlet water pressure. This ensures that polymer is always properly blended and activated regardless of water pressure fluctuations, eliminating the need to increase polymer dosing pump capacity to compensate for poor mixing. As a result, polymer consumption is optimized and waste is reduced, directly addressing the issue of increased consumption costs.
