Description
Technical field
The present invention relates to a kind of mixed uniformly mixing arrangement of several materials that is used for, a kind of dynamic mixer that mixes with pressed powder especially for liquid and liquid, liquid.
Background technology
In a lot of industry production, all relating to, such as the interpolation of various auxiliary agents in production, chemical fibre and the plastics-production of the production of missible oil type agricultural chemicals, printing ink etc. the mixed uniformly production link of several materials.These mixing of materials evenly whether extremely important is directly connected to the stability of production and the quality of product quality.
When several mixing of materials, usually a kind of material that consumption is more is referred to as major ingredient, and consumption less be referred to as auxiliary material.For various reasons, for example compatibility is relatively poor between major ingredient and the auxiliary material, auxiliary material is easy to generate agglomeration or major ingredient viscosity is unfavorable for auxiliary material dispersion etc. more greatly, evenly disperses to have made difficulty for auxiliary material in major ingredient.
Just because of this, many about the research of mixing of materials equipment, various mixing apparatus arise at the historic moment, such as various high speed gyratory shakers, static mixer, dynamic mixer, extruser etc.These mixing apparatus are mainly used to shear auxiliary material are disperseed in major ingredient, promptly strengthen shear effect, seldom have equipment to have the effect of auxiliary material being carried out multistage distribution simultaneously.
Such as high speed gyratory shaker, extruser etc., with the auxiliary material of reuniting repeatedly, the powerful shearing until aggregate disappear, finally be uniformly dispersed.But this kind equipment has two aspect drawbacks: because it is its brute force is sheared, kneading, bigger on the one hand to the material destructiveness, cause the polymeric resin degraded easily such as extruser; Application limitation is bigger on the other hand, such as the high speed gyratory shaker, and low viscosity mixing of materials in only being suitable for, inapplicable viscosity higher mixing of materials, extruser just is used for the viscosity higher mixing of materials, inapplicable middle low viscosity mixing of materials.
Along with the expansion of studying reaches deeply, wherein dynamically mixer is finally shown one's talent owing to have a lot of special performances.Such as Chinese patent CN2138556, on open July 21 1993 date, a kind of ball-and-socket type dynamic mixer is disclosed.This blender has used the method for designing of dynamic hybrid element and static mixing element, and the mixing head of mixed zone is designed to hemisphere nest shape.This design concept had both been strengthened shear effect, possesses multistage distribution function simultaneously mixed effect is increased.The design of this hemisphere nest shape hybrid element simultaneously is also for realizing that the equipment processing and manufacturing provides a kind of possibility.But there is a big drawback in this class ball-and-socket shape hybrid element, the movement locus of material after entering the mixed zone be forward, preceding on, downward again, similar walk snakelike, when polymer viscosity is higher, circulating resistance is very big, can't carry out multistage mixing, causes mixed effect limited, when this invention is applied to the high polymer manufacture field, very high in addition to the equipment processing request.
Deutsche Bundespatent WO00/32376 on June 8 2000 international publication day, discloses a kind of method of utilizing the equipment coagulating plastic dispersions of shearing elements in addition.Used a series of shearing elements in this invention,, the radial teeth array structure arranged and be star-arrangement at the outer surface of inner surface of stator and rotor as stator and rotor, stator and rotor complementation join and.The purposes of this equipment is to make plastics or rubber dispersion realize cohesion by emulsion polymerisation, is about to that very small (the polymer emulsion particle coacervation of 80nm～220nm) is than macroparticle, is beneficial to the most at last polymer and separates from aqueous medium.Its action principle is to utilize the minim gap between rotor outer surface and the stator inner surface that material is produced shear action, impels the microemulsion particle to condense, and its particle diameter is increased, and material mainly is to circulate by the gap between rotor outer surface and the stator inner surface.In order to obtain flocculating result preferably, the gap between preferred rotor outer surface and the stator inner surface will be in a small range, and its gap is 0.5mm～1.0mm from embodiment.To the analysis of above technical scheme as can be known, the movement locus of material in the inside of this equipment is the gap circulation between rotor and stator, and purpose is a coagulating plastic dispersions, does not have dispersion, mixed function.
In sum, although the mode that existing mixing arrangement has adopted dynamic hybrid element to cooperate with static mixing element, material be the movement locus complexity in mixing arrangement, circulating resistance is excessive, make it can not produce multistage effectively distribution, also reduced shear effect simultaneously material.
Summary of the invention
In order to overcome material movement locus complexity in the mixed zone in the existing mixing arrangement, circulating resistance is excessive, makes it can not produce multistage effectively distribution, the shortcoming of shear effect difference to material, it is little to the invention provides a kind of material stream passed resistance, the dynamic mixer of good mixing effect.

The quantity of preferred moving projection 91 is identical with the quantity of quiet groove, and moving projection 91 evenly distributes around the outer toroid circumferencial direction of dynamic hybrid element, and quiet groove 101 evenly distributes around the interior annulus circumferencial direction of static mixing element.
It is preferred that dynamically hybrid element 9 is identical with the quantity of static mixing element 10, each dynamic hybrid element 9 with replace close fit about static mixing element 10 is in mixing of materials device 5.But dynamically the gap between hybrid element 9 and the static mixing element 10 is also moderate.Dynamically the gap between hybrid element 9 and the static mixing element 10 is 0.1～10mm, is preferably 0.2～5.0mm, between further 0.3～1.5mm.Gap greatly then material lagging is caused waste and is cleaned difficulty in the gap, the gap is too little also to make the frictional force between dynamic hybrid element and static mixing element excessive easily, additionally increases energy consumption and wearing part.
Split type setting or integral type setting between the static mixing element 10, dynamically split type setting or integral type setting between the hybrid element 9.The interior annulus of static mixing element 10 has material with space between the center rotating shaft 1 and retains in the process of mixing, material will be difficult to move forward at this, also just become " dead angle " of mixing, fill so be preferably in herein, as a sleeve is set, the internal diameter of sleeve equals the diameter of center rotating shaft 1, and the external diameter of sleeve equals the diameter of the interior annulus of static mixing element 10.In like manner as can be known, the space also is " dead angle " of mixing between the outer toroid of dynamic hybrid element 9 and outer sleeve 7, and a sleeve also is set herein, and the external diameter of sleeve equals the internal diameter of outer sleeve 7, and the internal diameter of sleeve equals the external diameter of dynamic hybrid element 9.Sleeve between static mixing element and static mixing element can split type setting also can the integral type setting, dynamically the sleeve between hybrid element and dynamic hybrid element can split type setting also can the integral type setting.
The operation process of this dynamic mixer is, enter the inside of dynamic mixer from major ingredient charging aperture 2 and auxiliary material charging aperture 3 when material, pushed to mixing of materials device 5 by material propulsion plant 4 immediately, material has a very rough mixing in this process, and auxiliary material is present in the major ingredient with similar coherent condition.Dynamic hybrid element 9 in the mixing of materials device rotates with center rotating shaft 1 in the process of mixing of materials, and static mixing element 10 keeps static with outer sleeve 7.Dynamically hybrid element 9 and static mixing element 10 are provided with moving projection 91 and quiet groove 101, be arranged alternately about dynamically between hybrid element and the static mixing element, when dynamic hybrid element rotates to certain angle, dynamically the moving groove 92 of hybrid element is communicated with fully with the quiet groove 101 of static mixing element, formed the passage that can be communicated with the left and right sides of mixing of materials device, material is pushed ahead from this passage under the effect of material propulsion plant 4.Center rotating shaft 1 drives dynamic hybrid element continuation rotation then, material in the static mixing element passage can be subjected to the thrust of material propulsion plant 4 and the shear force of dynamic hybrid element 9 moves forward, the moving groove 92 that rotates to dynamic hybrid element up to dynamic hybrid element 9 no longer is communicated with the quiet groove 101 of static mixing element, above process is that material has been finished the mixed once distribution in the quiet groove 101 of static mixing element, if a plurality of static mixing elements are arranged and when dynamically alternately connecting about hybrid element, mixed allocation will be at the passage of static mixing element and is dynamically finished in the moving groove of hybrid element.
If dynamically the number of the moving projection 91 of hybrid element is n, the number of the quiet groove 101 of static mixing element also is n, and then dynamically hybrid element 9 whenever turns around with respect to static mixing element 10, and the number of times that material is sheared distribution is:
Material is sheared distribution number of times=n
2
When material flows out from above-mentioned static mixing element 10, when flowing into next dynamically hybrid element, be sheared again and distribute n
2Inferior, the further homogenizing of the distribution of auxiliary material in major ingredient.If total m hybrid element in the mixing of materials device 5, then material is sheared and distributes number of times to add up to:
Material is assigned with total degree=n
2 (m-1)
For example, dynamically the thick 5mm of hybrid element moves 12 of projections, the thick 5mm of static mixing element, 12 of quiet grooves, dynamically the gap between hybrid element and the static mixing element is 1mm, totally 10 hybrid elements are example, and promptly dynamically hybrid element and static mixing element respectively have 5:
Mixer total length=5 * 10+1 * (10-1)
＝59mm
Material is sheared distribution total degree=10
2 * (10-1)=10
18
This shows that length is the mixer of 59mm only, the present invention shears material and distributes number of times just can reach 10
18Inferior, so mixed effect of the present invention and efficient are very high.
When material in mixed process, when the passage of dynamic hybrid element when passage between static mixing element is not communicated with, the material in the static mixing element passage does not stress; When the passage of dynamic hybrid element rotates to when beginning to be communicated with the passage of static mixing element, the material in the static mixing element passage is subjected to the thrust of material propulsion plant and the dynamic shearing force of hybrid element.On macroscopic view, material passes through from the passage on dynamic hybrid element and the static mixing element, the direction of motion of the material in the static mixing element passage is the direction along center rotating shaft, and dynamically the direction of motion of the material in the hybrid element passage is axially circumferential with the outer sleeve circumference along center rotating shaft.As seen material can be to the radial motion of center rotating shaft in blender, and material is the diametric power of acceptor center turning cylinder no longer, does not promptly have away the phenomenon of " snakelike ", so significantly reduced circulating resistance.
Be mainly used in viscosity in thousands of extremely mixing of materials between tens thousand of centipoises, such as the printing ink production link.In process of production, key link is the even dispersion of pigment in connecting material.Because pigment particle size is very little, its specific area is very big, therefore is very easy to reunite, and causes it to be difficult to evenly disperse in connecting material.In common production process, mainly be to use the grinder repeated multiple times to grind, production efficiency is relatively low.
For solving such problem, these hybrid element characteristics are: 1, the groove relative narrower of hybrid element, darker; 2, hybrid element thinner thickness.
The shape of concrete dynamically hybrid element and static mixing element is seen Fig. 4, Fig. 5.Other structure of dynamic mixer is identical with embodiment 1.
In the present embodiment dynamic hybrid element upper groove is substituted with through hole, what this through hole can be in circle, rectangle, triangle, regular pentagon, the regular hexagon is a kind of, sees Fig. 6.The arrangement of this through hole on dynamic hybrid element can also be two rows that are arranged to different-diameter along the circumferencial direction of dynamic hybrid element, is arranged to two rows and can improves the quantity in hole in limited space, strengthens the effect of mixing and distribution, sees Fig. 7.
Simultaneously the groove on the static mixing element also replaces with through hole, and the size in hole, shape, distribution mode can be identical with the hole on the described dynamic hybrid element.Other parts are identical with embodiment 1, no longer repeat.
