Definitions

  • the invention relates to a static spray mixer for mixing and spraying of at least two flowable components according to the preamble of the independent claim.
  • Static mixers for mixing at least two flowable components are for example in the EP-A-0 749 776 and in the EP-A-0 815 929 described. Despite their simple, material-saving construction of their mixer structure, these very compact mixers produce good mixing results, especially when mixing highly viscous substances such as sealants, two-component foams, or two-component adhesives. Typically, such static mixers are designed for single use and are often used for curing products in which the mixer practically can not be cleaned.
  • the two components are atomized at the outlet of the mixer by exposure to a medium such as air and can then be applied in the form of a spray or spray on the desired substrate.
  • a medium such as air
  • Such a device is for example in the US-B-6,951,310 disclosed.
  • a tubular mixer housing which receives the mixing element for the static mixture and which on one end has an external thread on which an annular nozzle body is screwed.
  • the nozzle body also has an external thread.
  • a cone-shaped Zerstäuberelement is placed, which has on its conical surface a plurality of longitudinal grooves.
  • a cap is inverted, the inner surface is also designed conical, so that it rests against the conical surface of the atomizer. Consequently, the grooves form flow channels between the atomizer element and the cap.
  • the cap is fixed together with the atomizer element by means of a union nut, which is screwed onto the external thread of the nozzle body, on the nozzle body.
  • the nozzle body has a connection for compressed air. In operation, the compressed air flows from the nozzle body through the flow channels between the atomizer element and the cap and atomizes the material emerging from the mixing element.
  • a nozzle for atomizing a liquid in which the liquid is mixed with gas comprising a one-piece housing extending in the direction of a longitudinal axis to a distal end with an outlet opening, and a sputtering sleeve having an inner surface which the housing encloses in its end region, wherein the atomizing sleeve has an inlet for a pressurized atomizing medium is in EP 0 904 844 A1 described.
  • US 6,601,782 describes a spray nozzle assembly having a tubular, one-piece mixer housing extending in the direction of a longitudinal axis to a distal end with an outlet opening with a mixing element disposed in the mixer housing and a sputtering sleeve having an inner surface enclosing the mixer housing in its end region wherein the sputtering sleeve has an inlet for a pressurized sputtering medium.
  • a static spray mixer for mixing and spraying at least two flowable components, comprising a tubular, one-piece mixer housing which extends in the direction of a longitudinal axis up to a distal end which has an outlet opening for the components, with at least one in the Mixer element arranged to mix the components and with a sputtering sleeve having an inner surface which encloses the mixer housing in its end region, wherein the sputtering sleeve has an inlet for a pressurized sputtering medium.
  • a plurality of extending in the direction of the longitudinal axis grooves are provided through which the sputtering medium from the inlet of the sputtering sleeve to the distal end of the mixer housing can flow.
  • the inventive static spray mixer requires only three components, namely the one-piece mixer housing, the atomizer sleeve and the mixing element, which may also be configured in one piece. This results in a significant reduction in complexity compared to known devices and a much simpler manufacture or assembly.
  • each groove has a depth in the radial direction that increases toward the distal end of the mixer housing.
  • the mixer housing has a distal end portion that tapers toward the distal end. This rejuvenation improves the atomization effect.
  • the inner surface of the atomizing sleeve is configured to cooperate with the distal end portion.
  • the atomizing sleeve is connected thread-free with the mixer housing.
  • the outer surface of the mixer housing in the distal end region is at least partially designed as a frustoconical surface.
  • the truncated cone surface forms a cone angle with the longitudinal axis, which is at least 10 ° and at most 45 °.
  • annular space is preferably provided between the outer surface of the mixer housing and the inner surface of the Zerstäubungshüles, which is in fluid communication with the inlet of the atomizing sleeve and with the grooves.
  • each groove in the radial direction has a depth which is smaller, in particular at most half as large as the extension of the respective groove in the direction perpendicular to the longitudinal axis and the radial direction.
  • the atomizing sleeve is fastened by means of a sealing snap connection on the mixer housing.
  • the mixer housing has a substantially rectangular, preferably square, cross-sectional area perpendicular to the longitudinal axis outside the distal end region. This allows the proven mixers, available under the brand name Quadro®, to be used for the static spray mixer.

  • Fig. 2 a perspective view.
  • the spray mixer is used for mixing and spraying of at least two flowable components.
  • the spray mixer 1 comprises a tubular, one-piece mixer housing 2 which extends in the direction of a longitudinal axis A to a distal end 21.

Seen in the flow direction up to this stop 25, the interior of the mixer housing 2 has a substantially square cross-section for receiving the mixing element 3. At this stop 25, the interior of the mixer housing 2 is in a circular cone shape, thus has a circular cross-section and forms an exit region 26 which tapers in the direction of the distal end 21 and there opens into the outlet opening 22.

  • fixing means 42 are possible, such as a corrugation, a clamp, a crimp or crimp, a bayonet connection or the like.
  • the inlet 42 can be designed for all known connections, in particular also for a Luer lock.

  • the cone angle ⁇ which forms the outer surface of the mixer housing 2 in the distal end region 27 with the longitudinal axis A, is at least 10 ° and at most 45 °. This cone angle ⁇ is in general different from and especially smaller than the cone angle with which the output region 26 tapers in the interior of the mixer housing 2.
  • the inner surface of the atomizing sleeve 4 is configured to cooperate with the distal end portion 27.
  • the inner surface of the atomizing sleeve 4 is also designed as a frustoconical surface having the same cone angle ⁇ as the outer surface of the mixer housing 2 in this region K.
  • the inner surface of the atomizing sleeve 4 is initially still frusto-conical, but has a larger cross-section than the outer surface of the mixer housing 2, so that between the outer surface of the mixer housing 2 and the inner surface of the Zerstäuberhülse 4 an annular space 6 exists (see Fig. 7 ).
