Description

Technical Field

[0001] The invention relates to the technical field of solvent extraction detection, in particular to a liquid level detection device for a rapid solvent extraction system. Background Art

[0002] Rapid solvent extraction is a unit operation that utilizes the different solubilities of components in the system in the solvent to separate the mixture. It utilizes the difference in solubility or distribution coefficient of a substance in two immiscible solvents. At the same time, the rapid solvent extraction is carried out under high temperature (up to 200 degrees) and high pressure (1500psi). Based on this condition, the solute substance is transferred from one solvent to another. After the extraction is completed, the solvent is tested by a liquid level detection device to obtain the data of the solvent after extraction. However, the existing solvents are mostly operated in a static state at room temperature when mixed for extraction. However, this method has a low extraction efficiency and cannot meet the use requirements well.
