Abstract

The invention relates to a top-suspended low-power consumption and weak-shearing type liquid-liquid centrifugal extractor. The liquid-liquid centrifugal extractor includes a shell and a rotating drumwhich are coaxially arranged, the upper shaft end of the rotating drum is connected with a motor driving shaft by a shaft coupling, the lower shaft end of the rotating drum is suspended in the shell,the outer bottom surface of the shell is provided with a material mixing cylinder communicated with the internal of the shell and arranged coaxial with the rotating drum, a material-to-be-extracted inlet and an extractant inlet which are arranged along the tangential direction of the mixing cylinder are arranged in the outer side surface of the mixing cylinder, material dispersing blades are arranged on the inner side surface of the mixing cylinder, and a centripetal impeller structure arranged coaxial with the rotating drum is arranged on the inner bottom surface of the shell. The liquid-liquid centrifugal extractor realizes non-contact of the outer side surface of the rotating drum and the material, so the problems of power consumed by material stirring generated turbulent flow, power consumed by the contact friction with the material, wearing of the outer surface of the rotating drum by the material scouring and heat are solved, and the problem of material emulsification caused by the shearing effect of the side surface of the rotating drum on the material is also solved.

Description

technical field [0001] The invention belongs to the field of centrifugal extractors, in particular to a top-suspended low-power consumption weak-shear type liquid-liquid centrifugal extractor. Background technique [0002] Liquid-liquid centrifugal extractor is a fast and efficient liquid-liquid extraction and separation equipment. The principle is to use the centrifugal force generated by the centrifugal extractor during high-speed rotation to mix and transfer the two-phase liquids with different densities and immiscibles, and finally separate them to achieve the purpose of extraction. That is to say, a complete extraction process includes two processes: 1. Mass transfer process; 2. Separation process. The liquid-liquid centrifugal extractor can complete the two processes in the same equipment. [0003] The liquid-liquid centrifugal extraction machine is easy to achieve multi-stage countercurrent (cross-flow) series extraction. The single machine has the characteristics o...
