The principle of the Cyclone Sedimentation Device is primarily based on the intense rotational movement generated when water enters the equipment tangentially under specific pressure. This rotational flow produces centrifugal force, centripetal force, buoyancy, and fluid drag, which collectively cause less dense water to rise and exit through the outlet, while denser sand particles settle to the bottom of the device and are discharged through the waste outlet, achieving the purpose of sand removal.

Specifically, the vortex sedimentation device operates based on the principles of vortex and gravity sedimentation. The mixed liquid enters the equipment tangentially under pressure, creating a vortex and high-speed rotation. Due to the different densities of solids and liquids, they follow different paths within the sedimentation device. Heavier solid particles generate an outer vortex, moving downward along the inner wall of the equipment and settling into the tail pipe through the sedimentation holes. At the same time, the high-speed rotation inside forms a low-pressure area, creating an upward inner vortex that enters the cylinder through the center hole of the vortex arm and undergoes secondary filtration inside. The filtered liquid then enters the pump and is pumped to the surface, while the settled sand enters the tail pipe through the sedimentation holes and is released into the artificial well bottom after reaching a certain height through a release mechanism.

Additionally, the cyclone sand separator controls the flow state and velocity of water through mechanical force, causing sand particles in the wastewater to accelerate downwards in a spiral path along the pool wall under the influence of centrifugal force and gravity, thereby achieving the sedimentation of sand particles. Organic matter attached to the surface of the sand particles is washed off due to centrifugal force and collision, and enters the wastewater for subsequent treatment. The sand particles are separated by centrifugal force into the sand pit at the bottom of the sedimentation pool. As the sand particles accumulate and gradually compact, when there is an adequate amount of sand stored in the pit, they are extracted and transported to the sand-water separator for processing.

In summary, the working principle of the cyclone sand separator involves the centrifugal force generated by the rotational water flow, gravitational sedimentation, and the action of mechanical force, all working together to facilitate the separation of solid particles from the liquid.
