Definitions

  • the invention relates to a static mixing device for highly viscous media, especially for Plastic melting, according to the preamble of claim 1.
  • the invention also relates to a mixing element such a mixing device and for use this device.
  • the mixing element of this device has one Structure based on interlocking, itself crossing webs builds up, the webs two groups of structural elements aligned in parallel.
  • the mixing element 10 of Figure 1 is composed of the crossing webs 3 and 30 together.
  • Reference numeral 30 is assigned to the marginal ridges.
  • a neighboring one Mixing element 10 ' is indicated by dash-dotted lines.
  • the elliptical lines 35 and 36 give the edges of Surfaces by webs, not shown be spanned.
  • the surfaces with the edges 35 or 36 cross each other.
  • the two mixing elements 10 and 10 ' are the same, but one is 90 ° from the other another arranged rotated about the longitudinal axis.
  • the Longitudinal axis runs in the direction of arrow 4, which the Main flow direction represents.
  • Fig.2 shows the critical areas between the marginal webs 30 and the tube wall 2.
  • Through the thin arrows 4b is the weakly developed flow in the edge region, while the wide arrows 4a the stronger flow inside the mixing element 10 specify.
  • In the corner areas 40 between pipe wall 2 and marginal webs 30, in Fig.2 by a variety are marked by dots, the movement of the mixing medium practically to a standstill.
  • the marginal Web 30 removed and replaced by ribs 5.
  • the reinforcing ribs 5 can have just the length of the mixing element 1 (pulled out shown) or they can have extensions 5a (indicated by dash-dotted lines) in the neighboring Project mixing elements 1 'and 1' '.
  • the second case is shown in Figure 4, where in addition to the mixing element 1 3 two adjacent mixing elements 1 'and 1' '(with the associated reinforcing ribs 5 'and 5' ') can be seen.
  • the ribs 5, as shown in the mixing elements of FIGS. 3 and 4 are provided, shown as separate parts.
  • the ribs 5 are on the Places 51 connected to the side webs 31 (welded in the present example).
  • the ribs 5 can also be in the form of continuous, over the entire Length of the mixing device extending bars be educated.
  • all webs 3, 31 of the mixing element 1 of the same width are identical.
  • the distance between the lateral webs 31 and the tube wall 2 in the two segmental edge areas is not larger than one Web width.
  • the node lines 32a and 32b are given by crossing points of the webs 3 and 31 (see Fig. 1), ground in a wedge shape (see Fig. 3). Thanks to this wedge shape, the result is slightly smaller Pressure gradient during the mixing process. Also on the lateral node lines 33, the webs 3 and 31 with Advantage cut to the intersection and cut through 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. A disadvantageous effect on the mixing quality is practically not available.
  • the mixing element 1 shown in the drawings is provided for a tube 2 with a circular cross section.
  • the invention can of course be correspondingly also on mixing devices with others Apply cross-sectional shapes.
  • the mixing element - including the Reinforcing ribs - can take the form of a Welded construction can also be provided as a casting.
