Definitions

  • the release element is preferably arranged adjacent to the mixer housing, so that the wall flow is deflected via the release element.
  • This wall flow has a lower flow velocity than the flow in the mixing space formed by the installation body, which is free of wall effects.
  • an improved deflection of this wall flow and thus an improved mixing effect can be achieved by the detachment elements, so that the required overall length of the mixer can consequently be reduced.
  • Particularly advantageous results have been found for release elements which have between 20% and 50% reduction have the available for the fluid flow free cross-sectional area in the mixer.
  • a detachment element can be provided in at least one part of the installation body. It is also possible that only a single mounting body has a release element.
  • a mixing element 100 for a static mixer according to a first embodiment of the invention is shown.
  • the mixing element comprises an installation body 1, which is installed in a tubular housing, which is not shown.
  • the tubular housing serves as a boundary of a mixing chamber 20, which is located in the interior of the tubular housing.
  • a fluid to be mixed flows, which usually consists of at least two different components. In most cases, the components are in the liquid state or as viscous masses.
  • these include, for example, pastes, adhesives, but also fluids which find use in the medical field, which contain active pharmaceutical ingredients, or fluids for cosmetic applications, as well as foods.
  • such static mixers also find use as disposable mixers for mixing a thermosetting mix of flowable components, such as the mixture of multicomponent adhesives. Another preferred use is in the mixture of impression compounds in the dental field.
  • Fig. 5 shows a section through the second and third wall elements 8, 9 of the mounting body 1.
  • the viewing direction is in the flow direction, so that the first wall element 102 of the mounting body 101 is visible.
  • the deflecting element 111 adjoins the first wall element 102 of the installation body 101.
  • the deflecting element 111 includes a first opening 112, which is arranged on the side of the second side wall 104.
  • a second opening 113 and a third opening 114 are arranged on the side of the first side wall 103.
  • the second opening 113 and the third opening 114 are offset from the first opening 112.
  • the CoV becomes smaller.
  • the reduction of the coefficient of variation CoV was determined over a given mixer length with the same distribution and therefore also the same CoV before the mixers; the mixer, which has a smaller CoV after the given length, mixes more intensively or better.
