Principle of centrifugal extractor:

离心萃取机是利用离心力实现液液两相萃取、分离、混合传质、反应、洗涤等多功能设备。具有比重差(互不相融)的两相液借助离心力进行液液分离/萃取。由不融合的两相液分别进入离心萃取机内，通过旋转转子和混合叶轮进行充分混合，促使溶质转移，混合后吸入转子内部逐渐分离/萃取。分开的液相分别汇集到轻相重相的两收集腔并分别从出口排出。可以通过调换堰板和转速满足不同密度、不同粘度的物料。                                                                                                                                                                                       

Centrifugal extractor is a multi-functional equipment that realizes liquid-liquid two-phase extraction, separation, mixed mass transfer, reaction and washing by centrifugal force. Two-phase liquids with differential gravity (non-blending) are separated/extracted by centrifugal force. The non-fused two-phase liquid enters the centrifugal extractor respectively, and is fully mixed by rotating the rotor and mixing impeller to promote the transfer of solute. After mixing, it is sucked into the rotor to gradually separate/extract. The separated liquid phase is collected into two collecting cavities of the light phase and the heavy phase respectively and discharged from the outlet respectively. Materials of different densities and viscosities can be met by changing weir plates and rotating speeds.

A solution of one or more solutes (shown in blue) when a centrifugal extractor performs liquid-liquid separation/extraction. With a density difference, a non-fused solution (shown in yellow) enters the device mixing chamber. Rotate the drum and mixing impeller for material mixing (green). The mixture is sucked into the drum for phase separation, the centrifugal force of the drum and the gravity of the material disperse the heavy phase (blue) to the outside of the drum, and the heavy phase liquid overflows from the adjustable heavy phase weir plate to the heavy phase collection chamber and is discharged. The light phase liquid (yellow) spills from the light phase weir plate to the light phase collection chamber inside the drum.
