Description

Technical Field

[0001] The present application relates to the field of pharmaceutical extraction, and in particular, to a biological pharmaceutical extraction device. Background Art

[0002] Extraction is a unit operation that uses the different solubility of components in the system to separate the mixture. It is a method that uses the difference in solubility or distribution coefficient of substances in two immiscible (or slightly soluble) solvents to transfer solute substances from one solvent to another.

[0003] In the extraction technology of biopharmaceuticals, the extraction tank is one of the common extraction equipment. In the extraction tank technology, the light phase liquid inlet and outlet and the heavy phase liquid inlet and outlet of the extraction tank are usually connected by connecting pipes, and flanges are provided at the ends of the connecting pipes. The connecting pipes are connected to the pipelines for conveying the light phase liquid and the heavy phase liquid from the outside through the flanges. However, the matching connection between the flanges is completed by multiple bolts. The fixing or disassembly between the two flanges requires the multiple bolts to be rotated one by one, which is more troublesome and inconvenient, thereby making it more troublesome and inconvenient to connect the extraction tank with the pipelines for conveying the light phase liquid and the heavy phase liquid from the outside.

[0030] In the present application, one end of the positioning rod 220 is fixedly connected to one side of the connecting plate 210, and the rod body of the positioning rod 220 slides through the plate body of the limiting plate 120.
