Detailed Description

In order to facilitate understanding of the present invention, the following description is further provided with reference to the accompanying drawings.

As shown in fig. 1 and 2, the multiphase mixer of the present invention realizes the unpowered mixing of multiphase flow media by disposing the fluid mixing structure 2 in a multilayer arrangement inside the mixer outer cylinder 1. Each fluid mixing structure 2 comprises a plurality of fluid mixing units 21, the fluid mixing units 21 are key components for realizing the unpowered mixing of multiphase flow media, the fluid mixing units 21 are rotatable paddle structures, the paddle structures can adopt flat paddle structures or spiral paddle structures, and the number of the paddles on each fluid mixing unit 21 is 4-6. After the multi-phase flow medium is sent into the mixer from the feed inlet of the outer cylinder 1 of the mixer, the blades of the fluid mixing units 21 can be rotated by turbulence and turbulent flow generated when the multi-phase flow medium is sent into the mixer, the multi-phase flow medium is separated into a plurality of vortexes under the rotation of the fluid mixing units 21 when passing through the fluid mixing structures 2 of each layer and then mixed with each other, and finally the uniformly mixed multi-phase flow medium is discharged from the discharge outlet of the outer cylinder 1 of the mixer.

The utility model discloses in adopted multilayer fluid mixed structure 2, as shown in figure 1, fluid mixed structure 2 is the multilayer and distributes and along mixer urceolus 1 axial arrangement inside mixer urceolus 1. As shown in fig. 1 and 2, a plurality of fluid mixing units 21 on each fluid mixing structure 2 are installed through a mesh 3, a plurality of meshes 3 arranged along the axial direction of the mixer outer cylinder 1 are arranged in the mixer outer cylinder 1, rotating shafts 31 perpendicular to the meshes 3 are fixed at each intersection of the meshes 3, one fluid mixing unit 21 is rotatably connected to each rotating shaft 31, and the number of the meshes 3 is the same as that of the fluid mixing structures 2.
