Definitions

  • the invention relates to a static mixing device according to the preamble of claim 1.
  • a static mixing device is from US-A-4577258 known.
  • the object of the present invention was to one over US-A-4577258 to create more stable mixing device. This task is characterized by the Features of claim 1 solved.
  • Claims 2 to 5 relate to various Embodiments of the mixing device according to the invention.
  • the material from which the mixing elements are made is preferably a metallic alloy or a Plastic (claim 6).
  • the two sections are included Advantage welded together (claim 7).
  • Claim 8 relates to an advantageous mixing device more than one mixing element.
  • the mixing element 3 of Figure 1 is made up of the strip-like, essentially zigzag or undulating sections 1 and 2 together.
  • the section 1 comprises the mixing-effective webs 12, with between two of these webs 12 each have an opening 13.
  • At the Section 2 have the corresponding webs and openings the reference numerals 22 and 23.
  • the two sections 1 and 2 are connected to one another at the crossbars 11 and 21, for example by spot welding.
  • To the The webs 12 and 22 have outer extreme points Connectors 14 and 24 respectively.
  • Sections 1 and 2 can by punching from metal or plastic plates - and subsequent forming - are produced.
  • the Parts can also be injection molded.
  • Fig.2 shows how the mixing element 3 of Fig.1 in one tubular housing 4 is arranged. With arrow 5 is the main flow direction is given.
  • Section 1 is in the form of a rigid chain
  • the Chain links each have two parallel mixing bridges 12, lies in the second embodiment in 3 shows a corresponding chain, each with three webs 12 and two openings 13 before.
  • the third Embodiment, Figure 4 have the chain links only one mix-effective bridge.
  • Fig.5 represents a fourth embodiment Detail, in which the openings 13a and 13b (or 23a and 23b) by partially cutting out as well Bending of material are formed, the bent material 15a and 15b (or 25a and 25b) itself has the function of mixing-effective webs.
  • a mixing device comprises more than one Mixing element 3. It is advantageously provided that the adjacent mixing elements with respect to the Main flow direction at an angle of preferably -90 ° are pivoted against each other.
