Abstract

The invention discloses a full-automatic closed-circuit circular extraction device. The device comprises a magnetic stirring water bath pot, an evaporation kettle, an extraction kettle, ultrasonic/microwave auxiliary equipment, a condenser, a support frame, a horizontal support, an extraction container and a dual-sealing cover; a support is arranged at the pot bottom; the evaporation kettle is arranged in the pot; a sealing cover and a steam pipe are arranged on the top of the evaporation kettle; a flow guide pipe is arranged between the evaporation kettle and the extraction kettle; the dual-sealing cover comprises an inner cover and an outer cover; the outer cover is fixedly connected with the extraction kettle in a sealing mode; the extraction container is connected with the inner cover in a sealing mode; mesh holes are formed in the extraction container, and a return pipe is arranged on the inner cover; the condenser is fixed to the support frame and comprises a water cooling part, a natural cooling part and a drainage pipe; the drainage pipe is detachably connected with the return pipe in a sealing mode; the natural cooling part is detachably connected with the steam pipe in a sealing mode; the support frame, the magnetic stirring water bath pot and the ultrasonic/microwave auxiliary equipment are arranged on the horizontal support. The whole device is a closed-circuit system, no solvent is lost in the extraction process, and steam in the evaporation kettle serves as driving force for achieving automatic circulation of the whole system.

Description

technical field [0001] The invention relates to the technical field of extraction devices, in particular to a fully automatic closed-circuit circulation extraction device. Background technique [0002] Extraction, also known as solvent extraction or liquid-liquid extraction, also known as extraction, is a unit operation that uses the different solubility of the components in the system to separate the mixture. That is, it is a method of transferring a solute substance from one solvent to another by using the difference in solubility or partition coefficient of the substance in two mutually immiscible (or slightly soluble) solvents. Widely used in chemical, metallurgy, food and other industries. Although extraction is often used in chemical experiments, its operation does not cause changes or chemical reactions in the chemical composition of the extracted substance, so the extraction operation is a physical process. Extraction is one of the means used in organic chemistry l...
