Definitions

  • the invention relates to a static mixer, a device with a such mixer and a use of the mixer.
  • the mixing results of the mentioned mixers are in individual applications insufficient, especially in cases where components are mixed which have different values of their viscosity.
  • One insufficient mixing results in the fact that at least one Streamline made of only one of the components to be mixed passes through the mixer structure with virtually no or one to undergoes slow mixing with adjacent flow filaments.
  • One such flow thread is referred to herein as "mix resistant”.
  • Mixed-resistant flow filaments are mainly found in static mixers before, whose mixer structure from a periodic sequence of similar consists of elementary mixing chambers. But even with non-periodic Mixer structures can be observed mixing resistant flow filaments.
  • US-A-5 944 419 discloses current filament yarns in each mixer structure for better mixing of the components.
  • the object of the invention is to provide a static mixer whose Mixed result is improved over the known mixers. These The object is achieved by the static mixer defined in claim 1.
  • the static mixer comprises a plurality of mixing chambers, the one Forming mixer structure.
  • the mixing chambers are in a tube along a Pipe axis behind and arranged side by side. They are for mixing of at least two flowable components usable.
  • the Mixer structure represents a modification of a basic structure. In this Basic structure are the mixing chambers by radial, in the direction of Tube axis oriented walls and standing across the tube axis Walls demarcated against each other. Breakthroughs between adjacent Chambers in the radial walls form inputs and outputs for the mixing components.
  • the modification consists of structural changes at individual points of the basic structure. It is designed so that in the Flow of the components to be mixed is a transversal Dislocation of mixed-resistant flow threads results, these Flow threads are resistant to mixing with respect to the basic structure.
  • the impurities have in flow areas outside the mixed-resistant flow thread are, as a rule, a disadvantageous Effect on the mixing process. If this is the case, only just as many Defects are provided, as for a sufficient number of Dislocations of the mixed-resistant flow filaments is necessary.
  • the defects can be formed so that they do not directly on the mix-resistant flow thread, but indirectly by putting in their direct sphere of influence cause deflections, which in turn then influence the mixed-resistant flow thread.
  • An embodiment suitable impurities can be found empirically. One leads experiments with blending components that are differently colored, and compares the results for a basic structure with those of a modification of the Basic structure, whereby one can determine whether mix-resistant Streamline have actually been deployed.
  • a device 100 is indicated by dash-dotted lines.
  • the basic structure 1 consists of a variety of Mixing elements together, which are arranged in a tube 10 in a row are; or it consists of a bundle of four chambered strands, their mixing chambers 8 ("mixing chambers”) each between two closed ends 4a and 4b extend.
  • Each of the mixing elements includes two axial sections, each of the sections at least one assigned to the section dividing divider 2 and 3 (radial walls) is.
  • the dividers 2, 3 intersect and divide the pipe cross section in equal areas.
  • the faces are open or through Deflecting discs 4 covered. Further details can be seen in the Drawings, in particular in FIG. 6, which show an unmodified basic structure 1 "with a mixing chamber 8 shown completely.
  • the mixing chambers 8 of the basic structure 1 "are free of installation, the same size and offset from each other.
  • Two inputs 6a, 6b and two Form outputs 7a, 7b arranged in an alternate sequence Connections to four adjacent chambers.
  • Two side Reinforcing walls 5 extend over the entire length of the mixer. 1
  • the device 100 comprises a two-chambered container 100a, namely a cartridge, with chambers 101 and 102. These are used for separate Inclusion of two flowable components A and B. Through outlets of the container 100a, A and B can by means of pistons 111 and 112 in the tube 10 are pressed (arrows A ', B'). After mixing A with B in the static mixer 1, which consists of the tube 10 and the mixer structure 1 ' composed, the mixture passes through a nozzle 120 from the device 100 off.
  • the cartridge 100a may include more than two chambers.
  • the Tube 10 may be a tubular part that can be placed on the cartridge 100a be educated.
  • FIG. 2 A section along the line II - II is shown in Fig. 2.
  • the mixer structure 1 ' is traversed by the two components A and B, the same values for the Have viscosity.
  • Arrows in the mixing chamber 8 give the flow path (with the symbols 'circle with cross' and 'circle with point' arrows after below or above - refer to the image plane - mean).
  • the Flow pattern is after results of a numerical simulation drawn. As you can see, the flow threads appear to be similarly thick Layers; this means a good mixing.
  • Fig. 3 shows a corresponding representation as in Fig. 2, here for two Components A and B, their values for the viscosity by a factor of 100 are different.
  • the less viscous component B forms much narrower Layers as this component flows faster.
  • the flow threads unfold unevenly. Another unevenness is formed particularly strong over a cross-section perpendicular to the shown section is. These inequities have a bad one Mixing results.
  • the modification 9 according to FIGS. 4 and 7 is inclined Web 91 formed in the mixing chamber 8 ', the pipe axis 11 or axis the mixer structure 1 'is inclined.
  • the web 91 connects on a radial Wall 2 has an input 6b with an output 7a such that the Flow through the web 91 of the tube wall 10 in the direction of tube axis eleventh is deflected (arrow 91 '). Also the reversal is possible: one Flow deflection through the web 91 of the tube axis 11 in the direction Pipe wall 10.
  • the modification 9 according to Figures 5 and 8 is by shortening the Lengths of three adjacent chambers 81, 82 and 83 at the same time Reduction in the number of inputs or outputs formed.
  • the pair of the chambers 81 and 82 which lie one behind the other along the tube axis 11, arranged laterally from the third chamber 83.
  • a modification 9 advantageously includes several impurities Modification elements 91 (first modification) and 81, 82, 83, 92 (second Modification), preferably regularly over the entire length of the static mixer 1 are positioned.
  • Modification elements 91 and 81, 82, 83, 92 is particularly advantageous.
  • FIG. 9 summarized shown: a) broken wall pieces 93, 94th and 95 effecting bypass flows (arrows 93 ', 94' and 95 '); and b) added webs 96, the passages between mixing chambers 8 narrow.
  • FIG. 10 shows schematically by means of a cross section through the static mixer 1 mixed-resistant flow filaments 30 and 31.
