Description

Technical Field

[0002] In the existing extraction process, the extraction device is mainly composed of an extraction tank composed of a mixing chamber and a transport chamber as an extraction unit, and is composed of a plurality of extraction tanks connected in series, and the number of extraction tanks connected in series is fixed. After the mixed fluid of the aqueous phase liquid and the oil phase extraction liquid containing specific elements is mixed in the mixing chamber by a stirring device, it overflows into the transport chamber through an overflow device. Due to the density difference between the aqueous phase liquid and the oil phase extraction liquid, the mixed fluid of the aqueous phase liquid and the oil phase extraction liquid completes phase separation under the action of gravity, and the upper layer is the oil phase extraction liquid and the lower layer is the aqueous phase liquid.

[0003] During use of the existing extraction tank, due to the existence of dead corners in the extraction tank, the oil phase extraction liquid is retained in the dead corners in the extraction tank, resulting in a fluid short circuit problem in the oil phase extraction liquid, which in turn affects the extraction effect of the aqueous phase liquid and the oil phase extraction liquid, thereby affecting the use efficiency of the extraction tank.
