Embodiment Construction

[0027] see Figure 1 to Figure 6 As shown in the figure, the novel static-dynamic combined high-efficiency liquid-liquid mixing device of the present invention includes an outer tube 7 of a mixing device; the outer tube 7 contains at least two subunits of a fixed helical blade and a rotating impeller assembly, wherein the initial subunit is a fixed subunit. The helical vane subunit, followed by the rotating impeller assembly subunit.

[0028] When the outer tube 7 contains more than three subunits, the subunits of the fixed helical blade and the subunit of the rotating impeller assembly are alternately arranged and assembled. figure 1 , figure 2 The embodiment shown is a novel static-dynamic combined high-efficiency liquid-liquid mixing device with three subunits. The order of the three subunits set in the outer pipe 7 is: fixed helical blade subunit → rotating impeller assembly subunit → fixed helical blade subunit. unit. If there are four subunits, the order of setting i...

Abstract

The invention discloses a novel static and dynamic combined high-efficiency liquid-liquid mixing device. The device comprises an outer pipe, wherein at least two subunits, namely a fixed spiral blade subunit and a rotating impeller component subunit are arranged in the outer pipe; the rotating impeller component subunit is arranged behind the fixed spiral blade subunit; the fixed spiral blade subunit consists of a group of fixed spiral blades which are arranged in the outer pipe and unidirectionally spirally rotate 200 to 300 degrees; the rotating impeller component subunit comprises a group of rotating impellers which are arranged in the outer pipe, can rotate and are provided with shafts; the rotating impellers are provided with a group of rotating wheel blades which incline -20 to 60 degrees to the axial direction; and axial fixing frames are arranged on two end shafts of each rotating impeller. The device has the advantages of fixed mixing elements and the rotating impellers, and can efficiently mix two or more kinds of liquid.

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, there are usually two types of liquid-liquid mixing devices: stirring mixers and static mixers. [0003] The stirring mixer uses the mechanical rotating motion of the paddle to realize the stirring and mixing of the various components of the material. The different shapes of the paddles and the 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 for multiphase dispersion mixing systems, it is difficult to form uniform shear force by mechanical stirring, and mechanical stirring requires external power and consumes a lot of energy. [0004] The static mixer has no moving parts. Multiple sets of fixed mixin...
