Abstract
The utility model belongs to the technical field of machine devices and relates to a static mixer which mainly comprises a plurality of serially-connected duct-type mixing elements, wherein each mixing element comprises an inner pipe and a partition plate, and the inner layer and the outer layer of the inner pipe are communicated with each other through a plurality of small holes on the partition plate and the inner pipe. The mixing elements of the static mixer can be combined into building block type mixers by adjusting dimensions of the small holes so as to adapt to viscosity changing and the like during mixing. Due to the fact that diameters of the small holes are small, flowing speed of mixed liquid flowing through the small holes is high so that very strong turbulence can be formed, and mixing of the mixed liquid is even. When the static mixer serves as a reactor for emulsion polymerization, good emulsion effect can be formed through the strong turbulence.
Description
Technical field
The utility model belongs to mechanical equipment technical field, is specifically related to a kind of static mixer of static mixing equipment, particularly low-viscosity (mobile) liquid.
Background technology
Static mixer also is the duct type blender, is a kind of mixing apparatus that does not have moving component, and it mainly relies on the unique shaped design of hybrid element, and the immiscible multiple fluid of flow therein is evenly mixed.Static mixer is widely used in industries such as oil, chemical industry, grease, medicine, food.
Nineteen ninety-five, Ministry of Machine-Building Industry issued the standard JB/T7660 that mechanical industry is recommended the static mixer of usefulness; Defined the static mixer of several kinds of specifications such as SX, SV, SL, SH, SK, standardization is all played bigger facilitation to the production and the use of static mixer.
But the later static mixer of standardization also has shortcoming, and in some situation, these static mixers can't satisfy mixed effect.With a series of blenders, under same diameter, the specification of internal mix element is confirmed, is not easy to adjust or make up according to actual condition.
The SV type that is fit to viscosity material, respond well in the approaching mixing of gas-liquid mixed or two kinds of liquid fraction, like the mixed of two kinds of liquid with 1: 1, but under ratio differs bigger situation, during like 100: 1 mixed proportion, effect is just not ideal.Change if bigger viscosity has taken place when two kinds of liquid reactions, the SV type just has been not suitable for more.
Be fit to the models such as SK that heavy viscous material is used, effect is just poorer in to the mixing of viscosity material, and the low-viscosity (mobile) liquid that Comparative Examples differs bigger is difficult to the mixed effect that reaches satisfied.
In the industry of reality, some synthetic or polymerisations are arranged, less several kinds of molecular weight ratio often, the liquid that ratio of viscosities is lower, polymerization perhaps synthesizes higher liquid of viscosity or melt.The reactor of making these reactions of the static mixer of standard has certain degree of difficulty; These standard reaction devices and their combination; Mixing requirement that can't the adaptive response different phase also can't adapt to the viscosity situation that gradually changes, for this reason; Need to design a kind of static mixer of new construction, adapt to the gradual change situation of polymerisation medium viscosity.
Summary of the invention
The purpose of the utility model provides a kind of static mixer, to adapt to the various working in the polymerisation.
For achieving the above object; The mentality of designing of the utility model is such: adopt same static mixer hybrid element structure; On the size of certain key element, do a series of variation; Enable to adapt under the different viscosities fluid different flow situation, reach the needed reynolds number Re of well-mixed.
The main technical schemes of the utility model: static mixer, it is characterized in that it comprises the duct formula hybrid element of some series connection, pipe and dividing plate in said hybrid element comprises, between the internal layer of interior pipe and the skin through the some apertures UNICOM on interior pipe and the dividing plate.
Usually, static mixer often wants a plurality of hybrid elements series connection to use during as reactor, and above-mentioned ten hybrid elements series connection of the utility model can be done the reactor of polymerization aqueous acrylic emulsion.The long 60mm of hybrid element, interior external diameter of pipe 18mm, wall thickness 4mm; Dividing plate diameter 28mm, thick 4mm; Dividing plate hole diameter 2mm, 8 of quantity; Diameter of inner pipe 2mm, 16 of quantity, about dividing plate each 8.
The utility model can make the static mixing element appropriate answer the requirement in differential responses stage through regulating the diameter of aperture, according to the stage of reaction, forms cordwood static mixing element combination, and needn't adjust the outer dia of static mixer.This specific character is that several kinds of static mixers of recommending among the present JB/T7660 can't be accomplished.
The static mixer of the utility model because hole diameter is less, has higher flow rate during the mixing material flows small holes, form very strong turbulent flow, and it is very even that mixing material is mixed.When this static mixer was done the reactor of emulsion polymerisation, strong turbulent flow can form the good emulsifying effect.
Description of drawings
Accompanying drawing 1 is the cross-sectional view of the utility model embodiment hybrid element.
Among the figure, pipe in the 1-; The 2-dividing plate; Pipe aperture in the 3-; 4-dividing plate aperture.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.
Embodiment: the hybrid element of present embodiment static mixer is shown in accompanying drawing 1, and hybrid element comprises interior pipe 1 and dividing plate 2, passes through some interior pipe aperture 3 and dividing plate aperture 4 UNICOMs on interior pipe 1 and the dividing plate 2 between the internal layer of interior pipe 1 and the skin.
Among the embodiment, the skin of pipe 1 in mixing material enters into through interior pipe aperture 3 from interior pipe 1 internal layer enters into the right of dividing plate 2, the internal layer of pipe 1 in being entered into by interior pipe aperture 3 more again through dividing plate aperture 4 from the left side of dividing plate 2.
The static mixer of present embodiment is used as the reactor of polymerization aqueous acrylic emulsion, is composed in series by ten hybrid elements.The long 60mm of each hybrid element, external diameter of pipe 18mm in it, wall thickness 4mm; Dividing plate diameter 28mm, thick 4mm; Dividing plate hole diameter 2mm, 8 of quantity; In the pipe 16 of apertures are arranged, about dividing plate each 8, diameter 2mm.
