Acrylic Extractor Tank (extractor box, extractor, and mixing clarification unit) is a stepwise contact extraction equipment, consisting of a stirring system, mixing zone, clarification area, and phase separation zone. In each stage, the two immiscible liquid phases are stirred, mixed, clarified, and phased separately, thereby achieving mass transfer and separation of the target solute between different liquid phases.
Work Process
The specific working process of the extraction tank (mixed clarification tank) involves the feed liquid and extractant being pumped into the mixing chamber through their respective feed ports by a feed pump. A high-speed stirrer then mixes the feed liquid and extractant for mass transfer. Subsequently, they flow through overflow baffles into the clarification chamber, where they separate into light and heavy phases under gravity. The separated light and heavy phases enter different outlets, completing one extraction cycle. In actual production, the extraction tank is typically a multi-stage series configuration, including extraction, back-extraction, washing, and regeneration sections, among others, which should be configured according to the specific production process.

Mixed Mass Transfer Process
Raw Material IntroductionThe raw material liquid and the extractant are separately introduced into the mixing chamber of the extraction tank through their respective feed openings. 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, ensuring thorough contact and mixing between the raw material liquid and the extracting agent. Under the action of stirring, the solute is transferred from the raw material liquid to the extracting agent, forming a two-phase solution. The intensity and duration of stirring significantly impact the mass transfer efficiency; insufficient stirring can result in inadequate contact between the two phases, reducing the efficiency of mass transfer; excessive stirring 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 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 efficiency grade
●Simple Structure: The extraction tank typically consists of a tank body, interface adjustment tube, motor reducer, agitator shaft, impeller, speed controller, and a movable platform, with a relatively simple structure.
●Stable Operation and Strong 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.
● Scalable Reliability: Single-stage extraction rates and other design parameters remain relatively reliable after scaling up.
