Definitions

  • the present invention relates to a static mixing element for mixing flowable multicomponent masses such.
  • Such static mixing elements are arranged at the output openings of dispensers for such multi-component masses, where you mix the components of the masses when they flow through the static mixing element.
  • a plastic injection molding mixer with a cylindrical inner contour and formed therein, obliquely arranged webs, which form branches and mergers for the component mixture.
  • the mixer has two parts which are hingedly connected to each other via a film hinge. In the folded position, both parts are held together by a snap closure. The webs are formed in both parts of the mixer.
  • the mixing elements consist of two parts, which are hingedly connected to each other by hinges. In the mixing elements while flow channels and mixing chambers are arranged, which ensure a mixing of material flowing through the mixing elements. Both parts of the mixing elements in this case have parts of the flow channels and the mixing chambers.
  • a mixing element with a radially divided mixing channel is known in which elements are arranged with a plurality of mixing vanes.
  • the mixing vanes are designed as massive bodies that taper towards their free edge.
  • a mixing element which consists of a plurality of interconnected elements, each element comprising a cylindrical body, which is formed of two half-shells.
  • the hollow cylindrical body have in each case on opposite inner sides in each case inwardly projecting plates.
  • the object of the present invention is therefore to develop a mixing element of the aforementioned type, which avoids the aforementioned disadvantages. This is achieved according to the invention by the measures mentioned in claim 1.
  • the flag elements are at least partially hollow and the cavity is open to the outer surface of the shell part, whereby a preparation of the static mixing element is achieved.
  • corresponding projections can be provided on the mold of an injection molding machine.
  • the base of the flag elements 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 loss volume in the static mixing element, since dead corners do not have to be filled with mass or mixture to be mixed. As a result, the flag elements protrude into the opposing second shell part when the static mixing element is folded, so that no further flag element has to be formed there at the opposite location.
  • the flag elements in this case have a planar habit and form at least two planar surface sides lying transversely to the direction of flow.
  • the released section in the flow space serves to flow past a mass to be mixed on a flag element. Due to the overlapping of the flag elements from one shell part to the other now less total flow guide elements or flag elements are needed, whereby the tool costs can be reduced. It is therefore particularly advantageous if the flag elements are formed on only one shell part.
  • the flag elements each have a free end face whose contour is adapted to the inner contour of the other shell part.
  • the flag elements with a corresponding height above the sealing edges, in the folded state of the static mixing element can be positively brought up to the inner wall of the second shell part.
  • flag elements can not be brought completely to the opposite shell part, so that a change of the mixing plane is possible.
  • the flag elements form pairs that consist of two offset flag elements opposite each other.
  • This measure can be a advantageous mixing geometry are provided, wherein the flow direction is changed at the one pair of flag elements.
  • the flag elements of such a pair are at an angle, z. B. in the range of 20 ° to 80 °, inclined to the longitudinal direction of the static mixing element, whereby the mixing efficiency is further increased.
  • the material-saving production of the static mixing element can be further improved in that the columnar body are at least partially hollow and the cavity is open to the outer surface of the shell part.
  • corresponding pins or mandrels can be provided on the mold of an injection molding machine.
  • the base of the columnar body can be widened conically to bead-like, whereby more favorable flow transitions and uniform wall thicknesses can be achieved.
  • an embodiment of an inventive static mixing element 10 is shown by way of example, which by means of a arranged on this connection part 25 z. B. on an output device for multi-component masses such. B. a dispenser for two-component cartridges, can be attached.
  • the static mixing element 10 has a first shell part 11 and a second shell part 12, which are hingedly connected to each other via a connecting means formed as a film hinge 33.
  • 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 joined together to form 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 guide 20. 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 leave a section 35 free. This section can be designed differently for different flag elements 21, 22.
  • the flag elements 21, 22 are grouped in pairs 24, with the flag elements 21, 22 of a pair being offset from each other.
  • the flag elements 21, 22 lie at an angle ⁇ / ⁇ of about 70 ° to the longitudinal direction 13.
  • connecting means 30 which engage in the folded state of the shell parts 11, 12 designed as a counter-locking means 32 connecting means 30 and engage there.
