The invention discloses a self-absorption alternating extraction device, system and method and belongs to the technical field of extraction device. The device, system and method are designed to solve the problem that the existing device has a high price and is difficult to eliminate the emulsification. The self-absorption alternating extraction device comprises a driving device and a mixing tank for containing extract and extract to be extracted. A rotating shaft is vertically arranged in the mixing tank. At least one L-shaped hollow stirrer is arranged in the mixing tank. The stirrer is fixed on the rotating shaft. The first end of the stirrer close to the rotating shaft is located in one of the extract or extract to be extracted, and the second end of the stirrer away from the rotating shaft is located in the other one of the extract or extract to be extracted. The self-absorption alternating extraction device, system and method ensure that one of the two kinds of incompatible products to be extracted can uniformly distributed in the other one and realize a high extraction rate. The device, system and method have the advantages of simple structure, low cost and high emulsification difficulty.
Description
technical field [0001] The present invention relates to the technical field of extraction devices, in particular to a self-priming alternate extraction device, a self-priming alternate extraction system comprising a plurality of such self-priming alternate extraction devices, and The self-priming alternate extraction method of the suction alternate extraction system. Background technique [0002] In the process of product separation in the fields of metallurgy, pharmaceuticals, and biological fermentation, emulsification is prone to occur during the extraction process. Since the biological system is very sensitive to acid and alkali, organic solvents and mechanical shearing force, the extraction method using vigorous mixing with a stirring blade can easily cause inactivation and decomposition. [0003] In order to solve the problem of emulsification and emulsification of mixed solvents in the process of separation and purification of biological products, high-efficiency cen...
