Description

Novel packed tower extraction equipment Technical Field The utility model relates to the technical field of extraction equipment, and particularly discloses novel packed tower extraction equipment. Background Extraction, also known as solvent extraction or liquid-liquid extraction, is a unit operation that utilizes the differential solubility of components of the system in a solvent to separate a mixture. That is, the method is a method of transferring a solute substance from one solvent to the other solvent by utilizing the difference in solubility or partition coefficient of the substance in two solvents which are not compatible (or slightly soluble) with each other. Widely applied to the industries of chemistry, metallurgy, food and the like and is generally applied to the petroleum refining industry. The desired substances can be extracted from the solid or liquid mixture by extraction. Chinese patent No. CN221513578U discloses a novel packed column extraction equipment, through agitator motor, puddler and stirring vane that upper portion was equipped with in the extraction tower body, agitator motor drive puddler and stirring vane are getting the internal lower part of tower and rotating at uniform velocity for can carry out even stirring mixing to the material in the extraction tower body and handle, be favorable to improving the speed of equipment extraction, stirring vane is established in the puddler lower extreme outside through link and adapter sleeve slip cap moreover, the link downside passes through bearing frame and electric putter's telescopic link one end swivelling joint, make through electric putter drive telescopic link flexible regulation, thereby can adjust stirring vane use height, and then can satisfy the stirring use of the different liquid levels in the extraction tower body and handle, further improve the efficiency of equipment extraction.
