PMMA Extractor Tank (extractor box, extractor, and mixing clarification unit) is a stepwise 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.
Process of Work
The specific operating process of the extraction tank (mixed clarification tank) involves the liquid and extracting agent being fed into the mixing chamber through their respective feed ports by a feeding pump. A high-speed stirrer then facilitates the mixing and mass transfer between the liquid and extracting agent. Subsequently, the mixture flows through overflow baffles into the clarification chamber, where the two phases (light and heavy) are separated under the action of gravity. The separated phases then enter different outlets, completing one extraction cycle. In actual production, the extraction tank is typically a multi-stage series arrangement, including stages such as extraction, back-extraction, washing, and regeneration, among others. The specific configuration depends on the production process.

Mixed mass transfer process
Raw Material IntroductionThe raw material liquid and the extractant are separately fed into the mixing chamber of the extraction tank through their respective feed ports. For example, in hydrometallurgy, the aqueous solution containing metal ions serves as the raw material liquid, while the organic extractant is introduced into the mixing chamber as another liquid phase.
Agitate and mixThe mixing chamber is equipped with a stirrer that rotates at high speed, allowing the raw material liquid and solvent to fully contact and mix. Under the action of stirring, the solute is transferred from the raw material liquid to the solvent, forming a two-phase solution. The intensity and duration of stirring have a significant impact on the mass transfer efficiency. Insufficient stirring can result in inadequate contact between the two phases, reducing the mass transfer efficiency; excessive stirring, on the other hand, may lead to emulsification, increasing the difficulty of subsequent separation.
Separation process
Overflow enters clarification chamberThe mixed liquid enters the clarification chamber through overflow baffles. The clarification chamber is a spacious 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 different densities of the raw liquid and the extractant, under the action 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 on top, forming a clear phase interface.
Partial contact reduces mass transfer efficiency; excessive stirring can 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 adjustment pipe, motor reducer, stirrer shaft, stirrer blade, speed controller, and a movable platform, making its structure relatively simple.
●Stable Operation and Strong Adaptability: Due to the larger volume of the extraction tank and higher liquid storage capacity, it can accommodate fluctuations in the feed material within a certain range. After balancing the adjustment, the operation is relatively stable and highly adaptable.
● Amplified Reliability: Single-stage extraction rates and other design parameters remain relatively reliable after amplification.
