Definitions

  • the invention relates to a static mixer, a device with a such mixer and use of the mixer.
  • the mixing results of the mixers mentioned are for individual applications insufficient, especially in cases where components are mixed that have different values of their viscosity. On insufficient mixed result manifests itself in the fact that at least one Flow thread that only consists of one of the components to be mixed exists, the mixer structure passes through and practically no or one to experiences slow mixing with adjacent flow threads. On such flow threads are referred to here as "mix-resistant”. Mixing-resistant flow threads come mainly in static mixers before, whose mixer structure consists of a periodic sequence of similar elementary mixing chambers. But also for non-periodic ones Mixer-resistant flow threads can be observed in mixer structures.
  • the object of the invention is to provide a static mixer, the Mixing result compared to the known mixers is improved. This The object is achieved by the static mixer defined in claim 1.
  • the static mixer includes a plurality of mixing chambers, one Form mixer structure.
  • the mixing chambers are in a tube along one Pipe axis arranged behind and next to each other. They are for mixing usable from at least two flowable components.
  • the Mixer structure represents a modification of a basic structure. In this Basic structure are the mixing chambers through radial, in the direction of Pipe axis oriented walls and through walls that are transverse to the pipe axis Walls separated from each other. Breakthroughs between neighboring Chambers in the radial walls form entrances and exits for the mixing components.
  • the modification consists of structural changes at individual points in the basic structure. It is designed in such a way that Flow of the components to be mixed is a transversal Dislocation of mix-resistant flow threads results, this Flow threads are resistant to mixing with respect to the basic structure.
  • the impurities have flow areas outside of the mix-resistant flow thread are usually a disadvantage Effect on the mixing process. If this is the case, only as many should be used Impurities are provided, such as for a sufficient number of Dislocation of the mix-resistant flow threads is necessary.
  • the defects can be designed so that they are not directly on the mix resistant flow threads, but indirectly by acting in their direct sphere of influence cause diversions, which in turn then influence the mix-resistant flow thread.
  • An arrangement suitable defects can be found empirically.
  • a device 100 is indicated by dash-dotted lines in FIG. 1.
  • This contains a static mixer 1, the mixer structure 1 'of which is a regular, unmodified basic structure 1 "forms.
  • the mixer structure 1 ' is as Side view shown. It is known from EP-A-0 749 776 and EP-A- 0 815 929, in which the basic structure 1 "on two different Wise is described:
  • the basic structure 1 consists of a multitude of Mixing elements together, arranged in a tube 10 one behind the other are; or it consists of a bundle of four chambered strands, whose mixing chambers 8 (“mixing chambers”) each between extend two closed ends 4a and 4b.
  • the mixing chambers 8 of the basic structure 1 "are of the same size without any installation and staggered.
  • Two side Reinforcement 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.
  • a and B can be inserted into the tube by means of pistons 111 and 112 10 are pressed in (arrows A ', B').
  • static mixer 1 which consists of the tube 10 and the mixer structure 1 ' the mixture exits the device through a nozzle 120 100 out.
  • the cartridge 100a can comprise more than two chambers.
  • the Tube 10 can be a tube part that can be placed on the cartridge 100a be trained.
  • FIG. 2 A section along the line II - II is shown in Fig. 2.
  • the mixer structure 1 ' is flowed through by the two components A and B, the same values for the Have viscosity.
  • Arrows in the mixing chamber 8 indicate the flow pattern (with the symbols 'circle with cross' and 'circle with point' arrows following below or above - in relation to the image plane - mean).
  • the Flow pattern is based on results of a numerical simulation drawn. As you can see, the flow threads appear to be of similar thickness Layers; this means good mixing.
  • Fig. 3 shows a corresponding representation as in Fig. 2, here for two Components A and B, their viscosity values by a factor of 100 are different.
  • the less viscous component B is much narrower Layers because this component flows faster.
  • the flow threads spread unevenly. Another unevenness is particularly strong over a cross section perpendicular to shown section stands. These irregularities are bad Mixing results.
  • Web 91 is formed in the mixing chamber 8 'to the tube axis 11 or axis the mixer structure 1 'is inclined.
  • the web 91 connects on a radial Wall 2 has an entrance 6b with an exit 7a such that the Flow through the web 91 from the tube wall 10 in the direction of the tube axis 11 is deflected (arrow 91 ').
  • the reverse is also possible: one Flow deflection through the web 91 from the tube axis 11 in the direction Pipe wall 10.
  • the modification 9 according to FIGS. 5 and 8 is shortened by the Lengths of three adjacent chambers 81, 82 and 83 with simultaneous Reduced number of inputs or outputs.
  • the pair is the the chambers 81 and 82 which lie one behind the other along the tube axis 11, arranged laterally from the third chamber 83.
  • Two breakthroughs 7c and 92 make a connection (arrow 92 ') between the two chambers of the pair 81, 82 ago.
  • a modification 9 advantageously includes several defects Modification elements 91 (first modification) or 81, 82, 83, 92 (second Modification), which is preferably carried out regularly over the entire length of the static mixer 1 can be positioned.
  • Modification elements 91 first modification
  • second Modification second Modification
  • the mixer structures 11 'of the described embodiments are included Advantage each monolithic; you can in particular from one Injection molded thermoplastic.
  • the mixer structure 11 ' has one rectangular cross-section and includes four arranged side by side Chamber strands. Each line forms a series of 5 to 15 mixing chambers 8.
  • Each chamber 8 of the basic structure has a length that is 1.5 to 2.5 times is longer than a chamber width, this width being greater than 1 mm and is less than 10 mm, preferably at least 2 mm and at most 5 mm.
  • the device 100 is suitable for mixing a highly viscous Components A with at least one further component B, one around can have a factor 10 to 1000 lower viscosity.
  • the Mass flow of the other component can be for example, by a factor of 10, less than the mass flow of highly viscous components.
