Three-stage reverse centrifuging extracting device for pharmacy

Abstract

The invention discloses a three-stage reverse centrifuging extracting device for pharmacy. The three-stage reverse centrifuging extracting device comprises a base, wherein a first extracting tank is fixedly arranged at one side of the top end of the base, and is connected with a third extracting tank through a first charge pipe; one side of the third extracting tank is connected with a medicine discharge pipe; a support rod is welded with the bottom end of one side of the third extracting tank; a movable block is welded with the bottom end of the support rod, and is movably arranged in an opening groove; the opening groove is arranged on the base; the bottom part of the third extracting tank is connected with a residue discharge pipe; a damping gasket is fixedly arranged at the top end ofthe third extracting tank. The three-stage reverse centrifuging extracting device has the advantage that the movable rod is screwed into a thread groove of a fixed block by threads, and can be rotatedin the thread groove according to actual conditions, the extending length of the movable rod can be adjusted, and the contact area with extracting medicine liquor is changed, so that the centrifuge force field is changed, and the flexibility is higher.

Description

technical field [0001] The invention relates to the field of pharmacy, in particular to a three-stage countercurrent centrifugal extractor for pharmacy. Background technique [0002] Centrifugal extraction is to separate immiscible mixtures with different densities. Its characteristic is that under the action of the stirring paddle, the two phases are fully mixed for mass transfer, and then enter the high-speed rotating drum together, and in the centrifugal force field The solute is transferred, and then the liquid is separated and discharged. In the process of pharmaceutical preparation, a centrifugal extractor is required to extract the medicinal liquid. However, the centrifugal force field of the existing extractor is fixed, and the centrifugal position cannot be adjusted according to actual needs. Therefore, the requirement cannot be satisfied. Contents of the invention [0003] The purpose of the present invention is to provide a three-stage countercurrent centrifuga...
