Definitions

  • the invention relates to a static mixing device for highly viscous media, in particular for plastic melts, according to the preamble of claim 1.
  • the invention also relates to a mixing element of such a mixing device and to the use of this device.
  • the mixing element of this device has a structure which is composed of interlocking, intersecting webs, the webs forming two groups of structural elements aligned in parallel.
  • the mixing element 10 of FIG. 1 is composed of the crossing webs 3 and 30.
  • the reference symbol 30 is assigned to the marginal webs.
  • An adjacent mixing element 10 ' is indicated by dash-dotted lines.
  • the elliptical lines 35 and 36 indicate the edges of surfaces that are spanned by webs, not shown. The surfaces with the edges 35 and 36 cross each other.
  • the two mixing elements 10 and 10 ' are the same, but one is arranged rotated by 90 ° with respect to the other about the longitudinal axis.
  • the longitudinal axis runs in the direction of arrow 4, which represents the main direction of flow.
  • marginal webs 30 are omitted according to the invention, two open, segment-shaped marginal regions are formed which lie between the side edges of the lateral webs 31 (see FIG. 3) and the tube wall 2.
  • the medium can flow axially uninhibited through the segment-shaped edge regions. As has been shown experimentally, this measure remains with regard to the mixing quality without a significant negative effect.
  • the marginal webs 30 have been removed and replaced by ribs 5.
  • the reinforcing ribs 5 can have the length of the mixing element 1 (shown in solid lines) or they can have extensions 5a (indicated by dash-dotted lines) which protrude into the adjacent mixing elements 1 'and 1' '.
  • FIG. 4 shows the second case.
  • FIG. 4 where, in addition to the mixing element 1 of FIG. 3, two adjacent mixing elements 1 'and 1' '(with the associated reinforcing ribs 5' and 5 '') can be seen.
  • 5a and 5b the ribs 5, as provided in the mixing elements of FIGS. 3 and 4, are shown as separate parts.
  • the ribs 5 are connected at the points 51 to the side webs 31 (welded in the present example).
  • the ribs 5 can also be formed in the form of continuous bars extending over the entire length of the mixing device.
  • all the webs 3, 31 of the mixing element 1 are of the same width.
  • the distance between the lateral webs 31 and the tube wall 2 in the two segment-shaped edge regions is not greater than a web width.
  • the node lines 32a and 32b which are given by intersections of the webs 3 and 31 (cf. FIG. 1), are advantageously ground in a wedge shape (see FIG. 3). This wedge shape results in a slightly lower pressure gradient during the mixing process.
  • the webs 3 and 31 are advantageously cut to length and through to the crossing points a weld seam joined together. The reason for this measure is the same as for the omission of the marginal webs 30.
  • the modification to the lateral node lines 33 has the additional effect that the pressure gradient is further reduced. There is practically no adverse effect on the mixing quality.
  • FIG. 6 shows an example in which the rib 5 has a transverse extension 50 in its center.
  • the cross section of this extension 50 fills a sector 60 of the segment-shaped edge region between mixing element 1 and tube 2 (cf. FIG. 4).
  • the sector 60 is delimited by an arc 61 of the tube wall, by a partial section 62 of the side surface of the mixing element 1 and by two connecting sections 63 and 64.
  • the mixing element 1 shown in the drawings is provided for a tube 2 with a circular cross section.
  • the invention can of course also be correspondingly applied to mixing devices with other cross-sectional shapes.
  • the mixing element - including the reinforcing ribs - can also be provided as a casting instead of in the form of a welded construction.
