Description
本发明涉及一种萃取装置，特别是涉及一种全自动高效低乳化的液液萃取装置。 The invention relates to an extraction device, in particular to a liquid-liquid extraction device with automatic, high-efficiency and low emulsification.
萃取是利用化合物在两种互不相溶(或微溶)的溶剂中溶解度或分配系数的不同，使化合物从一种溶剂内转移到另外一种溶剂中从而将其提取出来的过程。萃取有两种方式，分别是液液萃取和固液萃取。液液萃取是用选定的溶剂分离液体混合物中某种组分，溶剂必须与被萃取的混合物液体不相溶，具有选择性的溶解能力，而且必须有好的热稳定性和化学稳定性，如用苯分离煤焦油中的酚，用有机溶剂分离石油馏分中的烯烃，用CCl4萃取水中的Br2。通过萃取，能从液体混合物中提取出所需要的化合物。现今萃取已应用于石油馏分的分离和精制，铀、钍、钚的提取和纯化，有色金属、稀有金属、贵重金属的提取和分离，抗菌素、有机酸、生物碱、血液有效成分的提取，以及废水处理等。液液萃取是最常见也是最常用的萃取手段,液液萃取有着操作简单、通用性好、溶剂选择灵活简单等优点，但是同时也存在着重复工作繁复特别是液液接触面易发生乳化等缺点，这都导致了传统液液萃取方式的萃取效率较低。目前的液液萃取装置无法克服传统液液萃取方式的诸多缺点。
Extraction is the process of transferring a compound from one solvent to another by extracting it by dissolving the solubility or partition coefficient of the compound in two mutually incompatible (or slightly soluble) solvents. There are two ways of extraction, liquid-liquid extraction and solid-liquid extraction. Liquid-liquid extraction is the separation of a component of a liquid mixture with a selected solvent. The solvent must be incompatible with the liquid of the extracted mixture, have selective solubility, and must have good thermal and chemical stability. For example, the phenol in the coal tar is separated by benzene, the olefin in the petroleum fraction is separated by an organic solvent, and Br 2 in the water is extracted with CCl 4 . By extraction, the desired compound can be extracted from the liquid mixture. Nowadays, the extraction has been applied to the separation and purification of petroleum fractions, the extraction and purification of uranium, strontium and barium, the extraction and separation of non-ferrous metals, rare metals and precious metals, the extraction of antibiotics, organic acids, alkaloids and active components of blood, and Waste water treatment, etc. Liquid-liquid extraction is the most common and most commonly used extraction method. Liquid-liquid extraction has the advantages of simple operation, good versatility, flexible and simple solvent selection, but also has the disadvantages of repeated work, especially liquid-liquid contact surface. This has led to a lower extraction efficiency of the traditional liquid-liquid extraction method. The current liquid-liquid extraction device cannot overcome the shortcomings of the traditional liquid-liquid extraction method.
本发明所要解决的技术问题是，提供一种全自动高效低乳化的液液萃取装置。The technical problem to be solved by the present invention is to provide a liquid-liquid extraction device with automatic, high-efficiency and low emulsification.

作为本发明的改进一，还包括设置在所述萃取反应容器中的搅拌子。As a modification of the present invention, a stirrer disposed in the extraction reaction vessel is further included.
作为本发明的改进二，所述泵为柱塞泵。As a second improvement of the present invention, the pump is a plunger pump.
作为本发明进一步的改进，还包括设置在所述萃取反应容器中的搅拌子。As a further improvement of the present invention, a stirrer disposed in the extraction reaction vessel is further included.

During the aqueous-organic liquid-liquid extraction, the two-phase solution will stratify in the test tube, and the layered two-phase solution can be connected through a conduit and a pump disposed on the conduit. During the extraction, the pump will continuously pump the upper liquid into the lower liquid or according to the actual needs, the lower liquid can be driven into the upper liquid. By continuously driving in, the two-phase solution can be fully mixed and reacted. Automatic extraction. The liquid dispersing mechanism disperses the driven liquid into minute droplets, which not only makes the contact between the two-phase solution more sufficient, thereby improving the extraction efficiency, and the liquid droplets and the liquid droplets to be injected are two-phase. The rapid mass transfer between the droplets causes the surface tension of the droplets to decrease, which accelerates the polymerization between the droplets, thereby reducing the emulsification during extraction. The pump is a plunger pump, and the flow rate and flow rate of the plunger pump can be precisely controlled, so that a suitable flow rate and flow rate can be set for different extraction solvents and extraction solutions, thereby obtaining high extraction efficiency. The present invention also includes a stirrer disposed in the extraction reaction vessel, and the stirring of the stirrer can disperse minute droplets from the liquid dispersion mechanism into droplets of a smaller volume, thereby forming W/O (oil) Water-in-water emulsion dispersion, in which the rapid mass transfer between the droplets and the liquid droplets to be injected by the smaller volume droplets causes the surface tension of the droplets to be further reduced again, causing polymerization between the droplets. Accelerating again, which further reduces the emulsification in the extraction. At the same time, the smaller volume of the droplets further increases the sufficiency of mixing between the two-phase liquids, thereby further improving the extraction efficiency.
