annular centrifugal extractor

Product description
The centrifugal extractor is a new, fast and efficient liquid-liquid extraction and separation equipment. It is fundamentally different in working principle from traditional extraction equipment such as mixing and clarifying tanks and extraction towers. The centrifugal extractor uses a motor to drive the drum to rotate at high speed. Two liquids with different densities and immiscible liquids are mixed and mass transferred under the action of the shear force generated by the rotation of the drum or blades, and the high-speed rotation of the drum produces Rapid separation under centrifugal force. Working principle:
This machine integrates mixing and separation into one unit and has a compact structure. Centrifugal force is used to accelerate the separation of liquid-liquid phases with a difference in specific gravity. The two unfused liquid phases enter the outer cavity of the rotor from the two feed nozzles and are rapidly mixed with the rotation of the rotor. The mixed liquid enters the interior of the rotor through the channel at the bottom of the rotor. The interior of the rotor with self-priming pump function is divided into four vertical cavities, and the incoming liquids are balanced with each other. The liquid gradually separates as it flows from bottom to top in the rotor.
The separation zone extends from the baffle plate to the light phase weir to ensure sufficient time to form the liquid-liquid interface. The separated liquid-liquid phases are collected into their respective collection chambers through light and heavy phase weirs, and discharged from their respective outlets. The heavy phase weir plate can be removed and replaced to change the weir plate diameter. Features
1. Small space occupied - direct motor drive, no transmission accessories, compact structure, saving floor space and operating space;
2. Strong adaptability - compared with traditional chamber-type and tower-type extraction equipment, the stage retention time is short, phase separation is rapid, and the adaptable flow ratio range is wide; it can meet different densities and different flow ratios by replacing weir plates and frequency control. Viscosity of liquid materials;
3. High extraction efficiency - phase equilibrium is established quickly, making it easy to realize single-stage or multi-stage series counter-current or cross-flow washing and extraction;
4. Good operating performance - fully automatic operation, can run continuously without interruption, and can also be used in small batches and multiple varieties;
5. Low investment cost - the internal volume of the machine is small, and the consumption of extraction agents, solvents or detergents is minimal;
6. Good sealing performance - meets the application environment and GMP specifications for explosion-proof and toxic, harmful and volatile media;
7. Multiple optional configurations - According to different needs, the machine can be equipped with an anti-emulsification device, a cleaning-in-place (CIP) mechanism, a frequency converter, etc.
