The automatic liquid-liquid extraction instrument is a common pretreatment operation in laboratories at all levels. Manual extraction is labor-intensive, inefficient, and poses a significant risk of inhaling toxic gases. Most common automatic liquid-liquid extraction devices are of reciprocating oscillation, 360-degree flip, stirring, and jet types, each with its own drawbacks. The first two require manual venting, which only saves on the oscillation process. The latter two can cause solvent evaporation and are difficult to clean. This automatic liquid-liquid extraction instrument absorbs the advantages of similar products, avoids the shortcomings, and creatively uses a closed-airflow oscillating internal circulation principle. It can be started with one button, automatically extracts, does not require venting during extraction, automatically cleans up after extraction, and the waste liquid is adsorbed by an activated carbon adsorption tank and automatically discharged. All operational instructions and parameters can be controlled via a liquid crystal touch screen. It boasts high automation, time and labor savings, energy conservation, and environmental protection. It is suitable for various liquid-liquid extraction scenarios in water quality monitoring, such as water oil and volatile substances.
Liquid extraction separation is a crucial unit operation in process industries. Traditional box-type mixing and clarification tanks have poor sealing performance, which makes organic phase volatilization prone to solvent loss and severe fire hazards. The successful application of the new equipment has reduced solvent loss and fire risks during liquid-liquid solvent extraction processes. It has also broken through the bottleneck of continuous production in some special liquid-liquid extraction systems in the chemical pharmaceutical production process, enhancing production capacity. It serves as a demonstration for the application in various liquid-liquid extraction fields such as hydrometallurgy, wastewater treatment, fine chemicals, petrochemicals, and more, and is of significant importance for promoting green and safe production in related enterprises.
The liquid-liquid extraction separation in chemical pharmaceutical processes (such as pesticides) involves complex system properties, such as strong solvency and volatility in the organic phase; strong acidity in the aqueous phase and frequent presence of chloride ions; high concentration of the substance to be extracted; significant changes in physical properties between the two phases before and after extraction; and emulsification sensitivity to pH. Continuous production using traditional box-type mixing clarification tanks is challenging, and the existing production process can only adopt batch operation with pots, resulting in low yield and unstable product quality. Batch operation leads to severe volatility of the organic phase, causing solvent loss while also deteriorating the working environment for workers and posing serious fire hazards.
The CHCQ-6 Automatic Liquid-Liquid Extraction Apparatus operates in an all-electric mode, comprising an extraction bottle, a gas-liquid pump, and a control section. It operates by utilizing air pressure to thoroughly mix and collide water samples with extraction agents, achieving complete extraction. It completely replaces manual shaking, reduces the labor intensity for experimenters, avoids direct contact with toxic reagents, and protects the health of the operators. The entire extraction process requires no manual venting, can automatically drain, and self-clean. Additionally, the automatic liquid-liquid extraction system significantly reduces environmental pollution, enhances extraction efficiency, and ensures stable and reliable analysis.
