PVC Extracting Tank(Extractor boxes, extractors, and mixing clarification units) are a series of contact extraction equipment, consisting of a mixing system, mixing zone, clarification zone, and phase separation zone. In each stage, the two immiscible liquid phases undergo mixing, clarification, and phase separation processes, thereby achieving mass transfer and separation of the target solute between different liquid phases.
Work Process
The specific operation process of the extraction tank (mixed clarification tank) involves the料液and extracting agent being pumped into the mixing chamber through their respective feed ports by the feed pump. A high-speed agitator then mixes the料液and extracting agent for mass transfer. Subsequently, the mixture flows through overflow baffles into the clarification chamber, where separation of the light and heavy phases is achieved under gravity. The separated light and heavy phases then enter different outlets, completing one extraction cycle. In actual production, the extraction tank is typically a multi-stage series configuration, including stages such as extraction, reverse extraction, washing, and regeneration, among others. The specific configuration should be based on the production process.

Mixed Mass Transfer Process
Raw Material IntroductionThe feedstock liquid and extractant are separately introduced into the mixing chamber of the extraction tank through their respective feed ports. For instance, in hydrometallurgy, the aqueous solution containing metal ions serves as the feedstock liquid, while the organic extractant is introduced as another liquid phase into the mixing chamber.
Agitate and mixThe mixing chamber is equipped with a blender, which rotates at high speed, allowing the raw material liquid and solvent to come into full contact and mix. Under the action of blending, the solute is transferred from the raw material liquid to the solvent, forming a two-phase solution. The intensity and duration of blending have a significant impact on the mass transfer efficiency; insufficient blending may result in inadequate contact between the two phases, reducing the mass transfer efficiency; excessive blending, on the other hand, may lead to emulsification, increasing the difficulty of subsequent separation.
Separation process
Overflow enters the clarification chamberThe mixed liquid enters the clarification chamber through overflow baffles. The clarification chamber is a spacious empty room with a large cavity volume, providing ample space for the liquid to settle and separate.
Gravity Natural SeparationIn the clarification chamber, due to the differing densities of the raw liquid and the extractant, under the influence of gravity, the two phases gradually separate. The denser phase (usually the heavy phase) sinks to the bottom, while the less dense phase (usually the light phase) floats to the top, forming a clear phase interface.
Partial contact reduces mass transfer efficiency; excessive stirring may lead to emulsification, increasing the difficulty of subsequent separation.
Key Features
● High-grade efficiency
●Simple Structure: The extraction tank typically consists of a tank body, interface regulating pipe, motor reducer, stirrer shaft, impeller, speed controller, and a movable platform, with a relatively simple structure.
●Stable Operation, High Adaptability: Due to the larger volume of the extraction tank and the higher liquid storage capacity, it can accommodate a certain range of fluctuations in the feedstock liquid. After balancing, the operation is relatively stable and highly adaptable.
● Scalability Reliability: Design parameters such as single-stage extraction rates remain relatively reliable after scaling up.
