Abstract: This invention involves a liquid-liquid separation device, which includes a centrifugal cylinder. The centrifugal cylinder maintains a liquid inlet/outlet, and centripetal float valve inside, which is mounted on the wall of a cylinder that produces the centrifugal force. Liquids of various densities enter the centrifugal cylinder; under the action of centrifugal force, the liquid medium of the highest density moves to the cylinder wall first, while the liquids of lower densities follow in sequence; when the inward buoyant force that the float bears in the liquids of various densities is greater than the outward centrifugal force generated due to its own mass, the float will move inwards to open the passageway and discharge the heavy medium deposited on the cylinder wall, thus achieving the automatic separation.

This invention allows the liquids of various densities to enter the centrifugal cylinder; under the action of centrifugal force, the liquid medium of the highest density approaches to the cylinder wall first, while the liquids of lower densities follow in sequence; when the inward buoyant force that the float bears in the liquids of various densities is over the outward centrifugal force generated due to its own mass, the float will move inwards to open the passageway and discharge the heavy medium deposited on the cylinder wall, thus achieving the automatic separation.
