Definitions

  • FIG. 1 shows a side view of a partial view of a first sub-mixer insert 2a comprising a longitudinal ridge L extending in the longitudinal direction 3a with four visible, each spaced over a respective space Za arranged Mixing elements 4.
  • the mixing elements 4 have mutually parallel base webs 6,6a, 6b and mutually parallel additional webs 7,7a, 7b, wherein the base webs 6,6a, 6b and the additional webs 7,7a, 7b are crossed each other.
  • a partial mixer insert usually has between two and ten mixing elements 4.
  • the illustrated sub-mixer insert 2a could be made of plastic as an injection molding or of metal in a suitable casting process. For reasons of casting technology, the mixing elements 4 are connected in the illustrated arrangement to the longitudinal rib 3a, in order to produce the partial mixer insert 2a by injection molding with an "open-close" tool.
  • the mixing element 4 could also be formed by more than three sub-mixer inserts 2a, 2b, 2c arranged one above the other, for example by four, five, six or more sub-mixer inserts 2a, 2b, 2c. Such a mixing element 4 could therefore also have a corresponding plurality of webs 6, 6a, 6b, 7, 7a, 7b lying next to one another on the end side.
  • This structure of longitudinally L successive and spaced intermediate mixing elements 4 could, for example, with the in FIG. 2 illustrated sub-mixer insert 2b with mixing elements 5 or with the in FIG. 7 shown sub-mixer insert 2c and 2d, forming the mixer elements 5, to be assembled.
  • the mixer elements 4 and 5 can also be created by the same number of sub-mixer inserts, as in the Figures 1 and 2 shown with a sub-mixer insert 2a, 2b, or as in FIG. 13 shown with two sub-mixer inserts 2a, 2b; 2c, 2d, or as in FIG. 15 only partially visible, each with three sub-mixer inserts 2a, 2b, 2c and not apparent sub-mixer inserts 2d, 2e, 2f.
  • This in FIG. 15 shown mixing element 4 has a substantially cylindrical outer contour on, for example, in FIG. 2 in the direction L outer contour shown.
  • the mixing elements 4,5 in the longitudinal direction L are designed to be substantially as long or slightly shorter than the spaces Za, Zb, so that the mixing elements 4,5 in the interstices Za, For example, are insertable.
  • the FIGS. 17 and 18 schematically show two sub-mixer inserts 2a, 2b with longitudinal webs 3a, 3b, on which mixing elements are arranged 4.5.
  • no such opening 3e is formed, wherein the webs 6,6a, 6b, 7,7a, 7b are configured so flexible, and for example made of plastic, that the webs 6,6a, 6b, 7,7a , 7b slightly distort where the longitudinal webs 3a, 3b, 3c, 3d are arranged to provide this space.
  • the additional webs 7, 7a, 7b could also be designed such that they are connected at their tips, where possible, also with the respective longitudinal web 3a, 3b, 3c, 3d.
