Novel static and dynamic structural liquid-liquid mixing device

Abstract

A novel static and dynamic structural liquid-liquid mixing device comprises an outer pipe, and is characterized in that at least two units are disposed inside the outer pipe by a periodic arrangement of firstly arranging a rotating impeller component unit and secondly arranging a static state mixing unit; a front rotating impeller component unit communicates with a rear static state mixing unit by a convergent channel, and a front static state mixing unit and a rear rotating impeller component unit occasionally communicates with an outlet of the device by a divergent channel; the rotating impeller component unit comprises a set of rotatable shaft-carrying rotating impellers disposed inside an outer tube, a set of blades oriented -20-60 degrees to the axial direction are arranged on the impellers, and shafts on two ends of the rotating impellers are respectively equipped with axial fixing frames; the static state mixing unit is formed by the combination of 2-4 tunnel subunits, and a set of fixed helical blades are disposed inside each tunnel subunit with each fixed helical blade unidirectionally screwing at angles of 120-270 degrees. According to the invention, by combining respective advantages of the rotating impellers and the fixed hybrid elements, two and more different liquids can be efficiently mixed.

Description

technical field [0001] The invention belongs to the technical field of liquid mixing, in particular to a mechanical device for mixing two or more different liquids. Background technique [0002] In practical applications, commonly used liquid-liquid mixing devices usually have two types: stirring mixer and static mixer. [0003] The agitating mixer is a mechanical agitator, which uses the mechanical rotation of the paddle to achieve the mixing of the various components of the material. The different shapes of the paddles and different movement methods cause great differences in the mixing effect, and the stirring speed is limited to a certain extent, and the mixing efficiency is not high. . For some liquids with high viscosity or multi-phase dispersion mixing system, it is difficult to form uniform shear force by mechanical stirring, and mechanical stirring requires external power, which consumes a lot of energy. [0004] The static mixer has no moving parts, and multiple ...
