Abstract

The invention relates to a pneumatic ultrasonic extraction device and an ultrasonic extraction method using the pneumatic ultrasonic extraction device. The device and the method can achieve continuousultrasonic extraction and are favorable for improving the extraction efficiency. According to the pneumatic ultrasonic extraction device, a solvent storage mechanism, a liquid inlet mechanism, a separate storage container, an extraction vessel and a concentration vessel are sequentially connected in series through a liquid pipeline; after a sample is added into the extraction vessel for extraction, extracted liquid can be pressed into the concentration vessel through a pneumatic circulating mechanism for concentration and constant volume, and an extraction solvent can be further supplementedinto the extraction vessel through the solvent storage mechanism and the separate storage container for further extraction, so that continuous ultrasonic extraction can be carried out. By means of thepneumatic circulation mode, repeated continuous extraction and circulation extraction can be achieved, pipeline pollution caused by a liquid pump can be reduced, and the risk of cross contamination is reduced. The pneumatic ultrasonic extraction device can automatically control all mechanisms to act through a control mechanism, excessive manual intervention is not needed, and the extraction efficiency is high.

Description

technical field [0001] The invention relates to the field of extraction, in particular to a pneumatic ultrasonic extraction device and an ultrasonic extraction method using the pneumatic ultrasonic extraction device. Background technique [0002] Extraction is also called extraction in the field of production. It is the process of transferring a substance from one solvent to another by using the difference in solubility or distribution coefficient of the substance in two immiscible (or slightly soluble) solvents. . Solid-liquid extraction, also called leaching, is the use of solvents to separate components in solid mixtures, such as leaching sugars from sugar beets with water, leaching soybean oil from soybeans with alcohol to increase oil production, and leaching from traditional Chinese medicines with water Active ingredients to prepare liquid extract (also known as "leaching" or "leaching"). [0003] Organic toxic substances refer to organic substances that are toxic an...
