Description

Technical Field

[0001] The utility model relates to a multiphase mixing and separating device. Background Art

[0002] Extraction, also known as solvent extraction, liquid-liquid extraction, or extraction, is a unit operation that separates mixtures by exploiting the different solubilities of components in a system.

The organic phase flows out from the organic phase outlet pipe interface, and the aqueous phase enters the aqueous phase chamber of the aqueous phase regulator from the aqueous phase outlet. The regulating rod is rotated to control the gap between the head and the overflow hole, thereby controlling the rate at which the aqueous phase enters the regulating chamber and, in turn, controls the discharge of the aqueous phase.
