Definitions

  • the material-saving production of the static mixing element can be further improved in that the flag elements and / or the columnar body are at least partially hollow and the cavity is open to the outer surface of the shell part.
  • corresponding projections, pins or mandrels can be provided on the mold of an injection molding machine.
  • the base of the flag elements and / or columnar body can be widened conically to bead-like, whereby favorable flow transitions and uniform wall thicknesses can be achieved. Due to the possible softer flow transitions there is a smaller dead or Veriustvolumen in Static mixing element, since dead corners do not have to be filled with mass or mixture to be mixed.
  • the static mixing element 10 has a first shell part 11 and a second shell part 12, which are connected to one another via a connecting means designed as a film hinge 33 connecting means.
  • Both shell parts 11, 12 are elongated and extend along a longitudinal direction 13 from an inlet opening 17 to an outlet opening 18 of the static mixing element 10.
  • By folding along the film hinge 33 both shell parts 11, 12 can be assembled into a tubular body. This is usually done during the manufacturing process of the static mixing element 10.
  • the shell parts 11, 12 each have two sealing edges 14, 15 on which both shell parts 11, 12 lie in the folded state together. Both shell parts 11, 12 embrace a flow space 16 for the mass to be mixed.
  • connection part 25 In the region of the inlet opening 17, the connection part 25 is arranged, which is formed here on one of the shell parts 12. A channel 26 in the connection part 25 goes directly into the flow space 16.
  • the connection part 25 may be connected to a fixing device, such as. As an internal thread to be provided for fixing to a fitting of a Auspressilless.
  • Flag elements 21, 22 are arranged as flow-guiding elements 20 on the first shell 11. These flag elements 21, 22 have a planar habit, wherein they have a base 29 which is flared towards the shell part 11. As a result, a soft transition to the inner surface of the shell part 11 is created.
  • the flag elements 21, 22 protrude beyond the sealing edges 14 of the first shell part and have a height which is designed so that their end faces 23 in the folded state reaches as far as the inner surface of the second shell part 12.
  • the contour or shape of the end faces 23 is adapted to the inner contour of the second shell part 12.
  • the flag elements 21, 22 are partially hollow, wherein the cavities 37, 38 are formed open to the outer surface 27 of the first shell part 11.
  • the flag elements 21, 22 in each case do not close off the entire flow space 16, but each leaves a section 35 free. This section can be designed differently for different flag elements 21, 22.
