Definitions

  • the invention relates to a static mixer for a curing mix according to the preamble of claim 1 and a use of the mixer.
  • the object of the invention is one with respect to said Disposable mixers to create improved mixer, for a longer Lifetime results. This object is achieved by the defined in claim 1 Mixer solved.
  • the static mixer is used for a curing mix of flowable Used components that when mixing to a solidifying React to mass.
  • the mixer comprises an injection molded article Installation body and the installation body sheathing pipe.
  • Of the Mounting body has a chamber through a plurality of mixing chambers on.
  • the mixing chambers are behind and behind a tube axis arranged side by side. By oriented in the direction of the tube axis, Radial longitudinal walls and transverse transverse to the tube axis transverse walls they are separated from each other. Breakthroughs between adjacent Chambers in the radial longitudinal walls provide input and output for the mix Exits.
  • Two parallel outer longitudinal walls are common in one used embodiment outside of the mixing chambers.
  • the filling namely the first angular filling, a concave surface spans to the interior of the mixing chamber.
  • the "concave surface” means a surface that at no Position is curved against the interior of the mixing chamber.
  • the Surface can also be flat in some areas:
  • the concave surface is concavely curved or forms together with the angular edges in the Cross-section of a "concave stretch", which approximates the course of a has concave curved curve.
  • a small wedge-shaped angle filling enters Example of a concave surface in the sense of the second meaning.
  • the dependent claims 2 to 9 relate to advantageous embodiments of the mixer according to the invention.
  • a use of the The mixer according to the invention is the subject of claim 10.
  • the fragmentary shown in Fig. 1 mixer structure of the Document EP-A-0 749 776 known disposable mixer is a through Injection molded installation body 1, in an unillustrated tube is inserted.
  • This the installation body 1 sheathing tube has a Interior with a square cross-section, into which the installation body 1 fits snugly.
  • the installation body 1 and the sheathing pipe could also be cylindrical: cf. Fig. 3.
  • From cartridges be by means of piston flowable components of a curing Blended through the pipe and the mounting body 1 pressed through, wherein the reactive Mischgutkomponenten to a solidifying mass be mixed.
  • the mounting body 1 has a chamber through a Variety of mixing chambers 2 on.
  • the mixing chambers 2 are along one Pipe axis 10 behind and arranged side by side.
  • radial Longitudinal walls 3a, 3b, 3c and 3d which are oriented in the direction of the tube axis 10 are, and transverse transverse to the tube axis 10 transverse walls 4a and 4b the mixing chambers 2 are delimited against each other. Breakthroughs 5a, 5b, 5c and 5d between adjacent chambers 2 set in the radial Longitudinal walls 3a, 3b, 3c and 3d inputs and outputs for the mix ago.
  • First outer sides 6a of the mixing chambers 2 are separated by two parallel outer longitudinal walls 6 formed. Between these longitudinal walls 6 have the Mixing chambers 2 each have a second outer side 6b, which is open and from not shown pipe is limited.
  • the outer longitudinal walls 6 can also missing. Form in the said frequently used embodiment the longitudinal walls 6, the first outer sides 6a.
  • FIG. 1 A mixing chamber 2 designed according to the invention is shown in FIG. With Arrows there is also the transport of the mix through the mixing chamber. 2 shown.
  • a current 12b enters.
  • the current 12a branches into partial streams 12ad and 12ac, which through the outputs 5d or 5c into adjacent mixing chambers. Accordingly, the current 12b branched into partial streams 12bd and 12bc, which together with the Partial streams 12ad and 12ac the mixing chamber completely shown in Fig. 2 2 leave.
  • first angular fill 7 tenses one concave surface 7a (as defined above) for Interior of the mixing chamber 2 on.
  • first angular filling 7 the conditions for the occurrence of a Stagnation defuses, which causes an extension of the service life.
  • Another measure in the form of a "second angular filling 8" carries in addition to an extension of the service life at: In the mixing chamber 2 close on the input side, the transverse wall 4a and the second outer side 6b an angle filled with wall material whose filling, namely the second angular fill 8, also a concave surface 8a to the interior the mixing chamber 2 spans.
  • the mode of action of this second Angular filling 8 is the same as that of the first angular filling. 7
  • first and / or second angular fillings 7, 8 at least partially are of different sizes, and each angular filling 7 or 8 equal to or smaller than the downstream angular fillings 7 or 8 is.
  • the angular fillings 7, 8 should not form too large accumulations of material, as already explained above. Therefore, it is advantageous if the following applies to the first angular filling 7 (and the like for the second Angular filling 8):
  • the concave surfaces 7a (or 8a) respectively a boundary line 7b to a flat surface part 4b '(or 4a') of the transverse wall 4b (or 4a) via; this boundary line 7b is intended in a middle strip of Transverse wall 4b lie, said strip the middle third of the transverse wall 4b occupied on the inside.
  • the concave surfaces 7a or 8a are each at least approximately part a circular cylinder.
  • the axis of this cylinder lies in a vertical to the tube axis 10 standing level.
  • the two angular fillings 7 and 8 associated cylinder axes are aligned perpendicular to each other.
  • the concave surfaces 7a and 8a each go with smooth Course in flat surface parts 4a 'and 4b' of the transverse walls 4a and 4b over. The same applies to transitions in planes on which the outer sides 6a or 6b of the mixing chamber 2 lie.
  • the second outside 6b of the mixing chamber 2 is through the second Angular filling in the area of a zone covered, whose area is not larger as the breakthrough area of the entrance 5a, which is to the transverse wall 4a borders. This condition results from the geometry of the tool, which is used as a mold in the injection molding device.
  • Fig. 3 is a cylindrical mounting body of the inventive mixer shown, which also has first and second angular fillings 7 and 8 respectively.
  • the outer longitudinal walls 6, which the first outer sides 6a of Form mixing chambers, have a circular segment-shaped cross-section.
  • the second outside 6b is curved. Accordingly, therefore, the one Flank of the second angular filling 8 curved.
  • Blend of components which, when mixed, solidify Mass react, at a largely constant or clocked varying pressing pressure, i. Pressure drop along the internals 1 of Mixer, mixed continuously or quasi-continuously.
  • the mixing will interrupted as well as the mixer replaced once a delivery of Mixture is noticeably smaller or an increase in the pressing pressure is required.
