Abstract
The utility model adopts a technical scheme as follows: a low-shear multi-element fluid static mixer is provided with a runner, wherein two ends of the runner are provided with interfaces, and the runner is internally and fixedly provided with more than two multi-direction rotational flow mixing units. The low-shear multi-element fluid static mixer is characterized in that each multi-direction rotational flow mixing unit is provided with inner-layer and outer-layer spiral fins which are connected onto a bracket, and the two layers of spiral fins are opposite in spiral direction. The low-shear multi-element fluid static mixer disclosed by the utility model can be used for sufficiently mixing general multi-element fluid, is particularly suitable for mixing the multi-element fluid under complicate conditions, eliminates the contradictions among blockage, shear rate and mixing unevenness, and is particularly specific to fluid mixing in special occasions, such three-element chemical injection of oil fields, chemical industry and pharmacy. The low-shear multi-element fluid static mixer fully reflects the technical features of high mixing degree, low shear and no blockage.
Description
Technical field
The utility model relates to a kind of blender, particularly relates to the polynary liquid static mixer of a kind of low shearing, mixes with other liquid for oil field, chemical industry, a kind of high viscosity liquid of pharmaceutical field.
Background technology
In the oil field, chemical industry, the production fields such as pharmacy usually need a kind of high viscosity liquid is mixed with other liquid, static mixer commonly used has X-type at present, L-type, the K type, the D type, V-type, the H type, the unit of Y type or above several form combinations, contradiction between mixing uniformity and the shearing during use, need larger shearing that mixed liquor is mixed preferably, if want to obtain the uniformity that low shearing certainly will be sacrificed mixing, it is very responsive for shearing when particularly oilfield polymer solution mixes, use above-mentioned static mixer, can't obtain with lower shearing high mixing uniformity; As in the oil field ternary injecting is used, alkali lye polymer solution table live agent solution with form extremely easily dirty matter obstruction mixed cell runner after oilfield sewage mixes, above-mentioned common blender can only require the fluid mixing without shearing to generic media.Can't satisfy the demanding fluid mixing of mixing such as polymer solution.
The utility model content
In order to overcome the easy fouling obstruction of existing static mixer runner, the low inhomogeneous problem of shear-mixed of high viscosity fluid, the utility model provides a kind of low shearing polynary liquid static mixer.
The technical solution adopted in the utility model is: the polynary liquid static mixer of a kind of low shearing, be provided with the runner of two ends band interface, be fixed with multidirectional eddy flow mixed cell in the runner, it is characterized in that multidirectional eddy flow mixed cell is provided with the inside and outside two-layer flight that is connected on the support, the two-layer flight hand of spiral is opposite, and this multidirectional eddy flow mixed cell is more than two.
Every helical layer sheet is more than two.
Adjacent multidirectional eddy flow mixed cell coaxial rotating 90 degree are placed, and connect by central shaft.
Flight is that the flight hand of spiral is opposite between adjacent layer more than three layers from inside to outside.
Outer flight pitch is 1/2nd to two times of external diameters.
Outermost layer flight pitch is 1/2nd to two times of external diameters.
The flight anglec of rotation is greater than 180 degree.
Each helical layer sheet pitch is different.
Be provided with the gap between each helical layer sheet, the gap is 1/2nd to times of flight width.
When the utility model uses, two or more pressure fluid enters forward axial flow of runner, under the effect of the flight of the different hands of spiral of multidirectional eddy flow mixed cell ectonexine, the ectonexine of fluid produces the circumferential movement of different directions, fluid produces soft distortion and disperses disturbance, simultaneously with fluid internal layer and the outer Radial Flow that produces that adjacent flight lower space is replenished, make mixing more abundant more even and shear low, because flow produces multi-direction disturbance during too much to the eddy flow mixed cell and washes away, can reach the purpose of avoiding the runner fouling to stop up.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the multidirectional eddy flow mixed cell of the utility model structural representation.
Number in the figure title: 1 interface; 2 runners; 3 supports; 4 flights; 5 central shafts.
The specific embodiment
The utility model embodiment as shown in Figure 1, 2, should lowly shear the runner 2 that polynary liquid static mixer is provided with two ends band interface 1, be fixed with multidirectional eddy flow mixed cell in the runner 2, multidirectional eddy flow mixed cell is provided with the inside and outside two-layer flight 4 that is connected on the support 3, two-layer flight 4 hands of spiral are opposite, every helical layer sheet 4 is two, this multidirectional eddy flow mixed cell is more than two, present embodiment adopts seven, adjacent multidirectional eddy flow mixed cell coaxial rotating 90 degree are placed, and connect by central shaft 5; During use, two or more pressure fluid enters forward axial flow of runner, under the effect of the flight of the different hands of spiral of multidirectional eddy flow mixed cell ectonexine, the ectonexine of fluid produces the circumferential movement of different directions, fluid produces soft distortion and disperses disturbance, simultaneously with fluid internal layer and the outer Radial Flow that produces that adjacent flight lower space is replenished, make mixing more abundant more even and shear low, because flow produces multi-direction disturbance during too much to the eddy flow mixed cell and washes away, can reach the purpose of avoiding the runner fouling to stop up, and simple in structure easy for installation.
Every helical layer head number can also greater than two, strengthen the dispersion dynamics when the utility model was implemented; Flight can be made as more than three layers from inside to outside, and the flight hand of spiral is opposite between adjacent layer, strengthens the distortion level; The pitch of outermost layer flight can be regulated in 1/2nd to two times of external diameters, mixes and keep shearing appropriateness for different viscosities liquid; The flight anglec of rotation is greater than 180 degree, and this angle can appropriateness increase to increase mixed effect, as when adopting a multidirectional eddy flow mixed cell; Can adopt different pitch between each helical layer sheet, regulate and answer melange effect between the fluid ectonexine; Between each helical layer sheet the gap can be set, the gap is regulated in 1/2nd to times of flight width, is used for keeping the shearing of appropriateness; Multidirectional eddy flow mixed cell quantity can regulate to reach the mixing requirement as required.
The utility model not only can fully mix general multi-element fluid, especially the multi-element fluid of usable condition complexity mixes, solved obstruction, shearing rate and mixed contradiction between the unevenness, injected medicament for oil field ternary especially, the fluid of the special occasions such as chemical industry, pharmacy mixes.Demonstrate fully high degree of mixing, low shearing, nonclogging technical characterstic.
