Turntable extracting tower

Abstract

The invention relates to a turntable extracting tower belonging to the technical field of separation equipment of pharmaceutical chemicals and comprising a tower body, a rotating shaft, a rotator, a power mechanism, an upper sedimentation tank with a heavy phase lead-in interface and a light phase lead-out interface, a lower sedimentation tank with a light phase lead-in interface and a heavy phase lead-out interface, and a separation disc distributed with separation disc through holes on the surface, wherein the rotator comprises a blade holder, a first blade and a second blade; the blade holder is fixed on the rotating shaft; the first blade and the second blade are formed on the blade holder and are arranged at intervals; and the first inclination angle of the first blade and the second inclination angle of the second blade face to opposite directions. The invention can avoid axial backmixing, enhance the interstage mixing effect, ensure the mass transfer of two phases in the tower, meet industrialized production requirements, simplify the structure and save the energy for driving the rotating shaft to rotate.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical and chemical separation equipment, and in particular relates to a rotary extraction tower. Background technique [0002] The rotating disk extraction tower, also known as the rotating disk tower, is an extraction tower with external energy. The structure of the widely used rotating disk extraction tower in the prior art is as follows: image 3 As shown, it includes a tower body 1, a rotating shaft 2, a rotator 3, a power mechanism 4 that drives the rotating shaft 2 to move, an upper settling tank 5, a lower settling tank 6, and a partition plate 7. Placed on the top of the upper settling tank 5, the upper settling tank 5 is connected to the top of the tower body 1, the lower settling tank 6 is connected to the lower part of the tower body 1, and there is a group of rotators 3, which are fixed on the rotating shaft 2 at intervals, and the partition plate 7 also has a group, fixed on the inn...

Problems solved by technology

However, the applicant believes that when the rotating shaft drives the rotator and the rotating baffle to rotate, the vortex caused by the rotator and the rotating baffle will still escape from the small holes on the rotating baffle, so there are still two phases. Axial mixing problems between, although to a much lower degree than image 3 Rotating disk extraction column with the structure shown

[0004] As mentioned above, although the rotary disk extraction tower has the advantages of simple structure, convenient operation, ideal mass transfer efficiency and low energy consumption, the maximization of mass transfer efficiency due to inter-stage back-mixing has always been concerned by the industry and urgently needed. technical issues to be resolved
