The specific embodiment

Following conjunction with figs. is elaborated to the utility model.

As shown in Figure 1, the utility model comprises one by tortuous pipeline mixing chamber 1 that constitutes and the some rotating vanes 2 that are arranged in the mixing chamber 1.Import and export at mixing chamber 1 is respectively arranged with and other pipeline flange connecting dish 3,4, mixing chamber 1 is some " several " font and is provided with continuously, and the length of its pipeline that both extended has avoided strengthening the volume of mixing chamber 1 again.

As Fig. 2, shown in Figure 3, the rotating vane 2 in the mixing chamber 1 is the stainless steel thin slices by a circle, through radial symmetric fluting 5, and the formation that rotates to an angle.The material of rotating vane 2 also can be made with other method or other material.The anglec of rotation of rotating vane 2 can be 60 ° or other angle.The quantity of fluting 5 can be two, four, or more, direction of rotation can be identical, or different, as shown in Figure 3, is to form relatively in twos.The axle center of adjacent rotating vane 2 is 90 ° and is crisscross arranged, and the direction of rotation of adjacent rotating vane 2 can be opposite.

In the foregoing description, mixing chamber 1 can also be spiraled to be provided with and constitute by some serpentine pipelines, and the what is called setting of spiraling both can be in the two-dimensional space inside turn, also can be in the three dimensions inside turn, and it all can reach and prolong pipeline length, the purpose of saving the space.

Owing between two adjacent rotating vanes 2, all reserve an intersegmental crack, therefore when glue flows through, under the effect of rotating vane 2, fluid is forced to produce " self rotates stirring " sometimes left-handedly, sometimes right, and fully mixes in the gap between two rotating vanes 2.

When the utility model uses, the ring flange 3,4 of mixing chamber 1 two ends import and export is connected on the pipeline between water, powder mixing arrangement and the High-efficient Stirrer of preparing fracturing fluid, need not other power-equipment, consumes energy not, only rely on the impulsive force of inflow line glue, just can produce rotation and mixing, reach the purpose of static mixing preferably.Being the influence of test the utility model to non-newtonian fluid, studying the situation of its mixing and viscosity, is object with the petroleum fracturing liquid, has done relevant test, concrete data following (annotate: different gelatin concentrations causes the difference of glue original viscosity):

By above-mentioned test data as can be known, through behind the static mixing device of the present utility model, the gelatin viscosity of variable concentrations has all had significant growth.Illustrate and adopt the mixing chamber 1 of tortuous pipeline to make glue further discharge viscosity by the collision of glue and tube wall, the interpolation of rotating vane 2 does not only cause degraded to gelatin viscosity, has quickened the release of viscosity all the better.The design of tortuous pipeline simultaneously makes the glue time of staying extend, and this also is one of necessary condition that adapts to the gelatin viscosity growth.The utility model can make the preparation glue in the rubber powder molecular distribution more even, can make gelatin viscosity discharge rapidly to a great extent again.Whole apparatus structure is simple, and appearance and size is little, and no movement parts need not maintenance, does not consume energy, and manufacturing cost and use cost is low, even can be considered the special pipeline of a cover that the dosing process medium fluid is flowed through.The utility model also can be applicable to relevant industries such as food, pharmacy, make between liquid or the uniform process of solid particle rapid mixing in liquid in reach viscosity abundant release become possibility.
