Description
Die Erfindung betrifft einen statischen Sprühmischer zum Mischen und Sprühen von mindestens zwei fliessfähigen Komponenten gemäss dem Oberbegriff des unabhängigen Patentanspruchs.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.
Statische Mischer zum Mischen von mindestens zwei fliessfähigen Komponenten sind beispielsweise in der
Bei einigen Anwendungen, bei denen solche statischen Mischer eingesetzt werden, ist es wünschenswert, die beiden Komponenten nach ihrer Durchmischung in dem statischen Mischer auf ein Substrat aufzusprühen. Dazu werden die durchmischten Komponenten am Ausgang des Mischers durch Beaufschlagung mit einem Medium wie beispielsweise Luft zerstäubt und können dann in Form eines Sprühstrahls oder Sprühnebels auf das gewünschte Substrat aufgebracht werden. Eine solche Vorrichtung ist beispielsweise in der
Bei dieser Vorrichtung ist ein rohrförmiges Mischergehäuse vorgesehen, welches das Mischelement für die statische Mischung aufnimmt und welches an einem Ende ein Aussengewinde aufweist, auf das ein ringförmiger Düsenkörper aufgeschraubt wird. Der Düsenkörper weist ebenfalls ein Aussengewinde auf. Auf das Ende des Mischelements, das aus dem Mischergehäuse herausschaut, wird ein konusförmiges Zerstäuberelement aufgesetzt, das auf seiner Konusfläche mehrere in Längsrichtung verlaufende Nuten aufweist. Über dieses Zerstäuberelement wird eine Kappe gestülpt, deren Innenfläche ebenfalls konisch ausgestaltet ist, sodass sie an der Konusfläche des Zerstäuberelements anliegt. Folglich bilden die Nuten Strömungskanäle zwischen dem Zerstäuberelement und der Kappe. Die Kappe wird zusammen mit dem Zerstäuberelement mittels einer Überwurfmutter, die auf das Aussengewinde des Düsenkörpers aufgeschraubt wird, am Düsenkörper fixiert. Der Düsenkörper weist einen Anschluss für Drucklust auf. Im Betrieb strömt die Druckluft aus dem Düsenkörper durch die Strömungskanäle zwischen dem Zerstäuberelement und der Kappe hindurch und zerstäubt das aus dem Mischelement austretende Material.In this device, a tubular mixer housing is provided, which receives the mixing element for the static mixture and which has an external thread at one end, onto which an annular nozzle body is screwed. The nozzle body also has an external thread. On the end of the mixing element, which looks out from the mixer housing, a cone-shaped Zerstäuberelement is placed, which has on its conical surface a plurality of longitudinal grooves. About this Zerstäuberelement 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 pressure. 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.
Auch wenn sich diese Vorrichtung als durchaus funktionstüchtig erwiesen hat, so ist ihr Aufbau sehr komplex und die Montage ist aufwändig, sodass die Vorrichtung insbesondere im Hinblick auf den Einmalgebrauch nicht sehr wirtschaftlich ist.Although this device has proven to be quite functional, so its structure is very complex and the assembly is complex, so that the device is not very economical, especially in terms of single use.
Ausgehend von diesem Stand der Technik ist es daher eine Aufgabe der Erfindung, einen besonders einfachen statischen Sprühmischer zum Mischen und Sprühen von mindestens zwei fliessfähigen Komponenten vorzuschlagen, der wirtschaftlich in der Herstellung ist und ein effizientes Durchmischen und Zerstäuben der Komponenten ermöglicht.Based on this prior art, it is therefore an object of the invention to propose a particularly simple static spray mixer for mixing and spraying of at least two flowable components, which is economical to manufacture and allows efficient mixing and atomization of the components.
Der diese Aufgabe lösenden Gegenstand der Erfindung ist durch die Merkmale des unabhängigen Patentanspruchs gekennzeichnet.The object of the invention solving this object is characterized by the features of the independent claim.
Erfindungsgemäss wird also ein statischer Sprühmischer zum Mischen und Sprühen von mindestens zwei fliessfähigen Komponenten vorgeschlagen, mit einem rohrförmigen, einstückigen Mischergehäuse, das sich in Richtung einer Längsachse bis zu einem distalen Ende erstreckt, welches eine Austrittsöffnung für die Komponenten aufweist, mit mindestens einem in dem Mischergehäuse angeordneten Mischelement zum Durchmischen der Komponenten sowie mit einer Zerstäubungshülse, die eine Innenfläche aufweist, welche das Mischergehäuse in seinem Endbereich umschliesst, wobei die Zerstäubungshülse einen Einlass für ein unter Druck stehendes Zerstäubungsmedium aufweist. In der Aussenfläche des Mischergehäuses oder in der Innenfläche der Zerstäubungshülse sind mehrere sich jeweils in Richtung der Längsachse erstreckende Nuten vorgesehen, durch welche das Zerstäubungsmedium vom Einlass der Zerstäubungshülse zum distalen Ende des Mischergehäuses strömen kann.Thus, according to the invention, a static spray mixer is proposed for mixing and spraying at least two flowable components, with a tubular, one-piece mixer housing extending in the direction a longitudinal axis extending to a distal end having an outlet opening for the components, with at least one arranged in the mixer housing mixing element for mixing the components as well as with a Zerstäubungshülse having an inner surface which encloses the mixer housing in its end region, wherein the Zerstäubungshülse having an inlet for a pressurized sputtering medium. In the outer surface of the mixer housing or in the inner surface of the Zerstäubungshülse a plurality of each extending in the direction of the longitudinal axis grooves are provided through which the Zerstäubungsmedium can flow from the inlet of the atomizer to the distal end of the mixer housing.
Durch diese Massnahmen resultiert eine besonders einfache Struktur des statischen Sprühmischers, ohne dass hierfür Zugeständnisse an die Qualität des Mischens oder des Zerstäubens vonnöten sind. Die optimale Nutzung der einzelnen Bauteile ermöglicht eine kostengünstige und wirtschaftliche Herstellung der Sprühmischer, die zudem - zumindest weitgehend - automatisiert durchgeführt werden kann. Grundsätzlich benötigt der erfindungsgemässe statische Sprühmischer nur drei Bauteile, nämlich das einstückige Mischergehäuse, die Zerstäuberhülse sowie das Mischelement, das ebenfalls einstückig ausgestaltet sein kann. Hieraus resultiert eine deutliche Reduktion der Komplexität im Vergleich zu bekannten Vorrichtungen und eine wesentlich einfachere Herstellung bzw. Montage.These measures result in a particularly simple structure of the static spray mixer, without requiring concessions on the quality of mixing or atomization. The optimal use of the individual components enables a cost-effective and economical production of the spray mixers, which moreover can-at least largely-be carried out automatically. Basically, 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.
Um insbesondere die Herstellung noch weiter zu vereinfachen, ist es vorteilhaft, wenn die Zerstäubungshülse gewindefrei mit dem Mischergehäuse verbunden ist.In order in particular to simplify the production still further, it is advantageous if the atomizing sleeve is connected thread-free with the mixer housing.
Bei einem bevorzugten Ausführungsbeispiel weist das Mischergehäuse einen distalen Endbereich auf, der sich auf das distale Ende hin verjüngt und bei welchem die Innenfläche der Zerstäubungshülse zum Zusammenwirken mit dem distalen Endbereich ausgestaltet ist. Durch diese Verjüngung wird der Zerstäubungseffekt verbessert.In a preferred embodiment, the mixer housing has a distal end portion which tapers towards the distal end and wherein the inner surface of the atomizing sleeve is configured to cooperate with the distal end portion. This rejuvenation improves the atomization effect.
Vorzugsweise ist die Aussenfläche des Mischergehäuses im distalen Endbereich zumindest teilweise als Kegelstumpffläche ausgestaltet.Preferably, the outer surface of the mixer housing in the distal end region is at least partially designed as a frustoconical surface.
Dabei hat es sich als vorteilhaft erwiesen, wenn die Kegelstumpffläche mit der Längsachse einen Konuswinkel bildet, der mindestens 10° und höchstens 45° beträgt.It has proved to be advantageous if the truncated cone surface forms a cone angle with the longitudinal axis, which is at least 10 ° and at most 45 °.
Um eine gleichmässige Verteilung des Zerstäubungsmediums auf die Nuten zu realisieren, ist vorzugsweise zwischen der Aussenfläche des Mischergehäuses und der Innenfläche der Zerstäubungshüles ein Ringraum vorgesehen, welcher mit dem Einlass der Zerstäubungshülse und mit den Nuten in Strömungsverbindung steht.In order to realize a uniform distribution of the atomizing medium on the grooves, an 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.
Damit das aus der Austrittsöffnung des Mischergehäuses austretende Material möglichst homogen zerstäubt wird, ist es bevorzugt, die Nuten gleichmässig über die Aussenfläche des Mischergehäuses zu verteilen.So that the material emerging from the outlet opening of the mixer housing is atomized as homogeneously as possible, it is preferred to distribute the grooves uniformly over the outer surface of the mixer housing.
Bezüglich der Geometrie der Nuten hat es sich als vorteilhaft erwiesen, wenn jede Nut in der radialen Richtung eine Tiefe aufweist, die kleiner ist, insbesondere höchstens halb so gross, wie die Erstreckung der jeweiligen Nut in der zur Längsachse und zur radialen Richtung senkrechten Richtung.With respect to the geometry of the grooves, it has proved to be advantageous if 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.
Insbesondere sind solche Ausgestaltungen bevorzugt, bei welchem jede Nut in der radialen Richtung eine Tiefe aufweist, die zum distalen Ende des Mischergehäuses hin zunimmt.In particular, those embodiments are preferred in which each groove has a depth in the radial direction that increases toward the distal end of the mixer housing.
Im Hinblick auf eine besonders einfache Herstellung bzw. Montage ist es vorteilhaft, wenn die Zerstäubungshülse mittels einer dichtenden Schnappverbindung am Mischergehäuse befestigt ist.With regard to a particularly simple production or assembly, it is advantageous if the atomizing sleeve is fastened by means of a sealing snap connection on the mixer housing.
Bei einem bevorzugten Ausführungsbeispiel weist das Mischergehäuse ausserhalb des distalen Endbereichs einen im wesentlichen rechteckige, vorzugsweise quadratische, Querschnittsfläche senkrecht zur Längsachse auf. Dadurch können die bewährten Mischer, die unter dem Markennamen Quadro® erhältlich sind, für den statischen Sprühmischer verwendet werden.In a preferred embodiment, 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.
Daher ist es auch bevorzugt, dass das Mischelement senkrecht zur Längsrichtung rechteckig, vorzugsweise quadratisch, ausgestaltet ist, so wie dies bei den Quadro®-Mischern der Fall ist.Therefore, it is also preferred that the mixing element is rectangular, preferably square, perpendicular to the longitudinal direction, as is the case with the Quadro® mixers.
Um eine sichere Zuführung des Zerstäubungsmediums zu gewährleisten, weist der Einlass der Zerstäubungshülse vorzugsweise Fixiermittel für eine Zuführung für das Zerstäubungsmittel auf.In order to ensure a reliable supply of the atomizing medium, the inlet of the atomizing sleeve preferably has fixing means for a supply for the atomizing agent.
Im Hinblick auf eine besonders einfache und kostengünstige Herstellung ist es vorteilhaft, wenn das Mischergehäuse und/oder die Zerstäubungshülse spritzgegossen sind, vorzugsweise aus einem Thermoplast.With regard to a particularly simple and cost-effective production, it is advantageous if the mixer housing and / or the atomizing sleeve are injection-molded, preferably made of a thermoplastic.
Aus dem gleichen Grund ist es vorteilhaft, wenn das Mischelement einstückig ausgestaltet und spritzgegossen ist, vorzugsweise aus einem Thermoplast.For the same reason, it is advantageous if the mixing element is configured in one piece and injection-molded, preferably of a thermoplastic.
Weiter vorteilhafte Massnahmen und Ausgestaltungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.Further advantageous measures and embodiments of the invention will become apparent from the dependent claims.

Im Folgenden wird auf den für die Praxis besonders relevanten Fall Bezug genommen, dass genau zwei Komponenten gemischt und gesprüht werden. Es versteht sich aber, dass die Erfindung auch für die Durchmischung und das Sprühen von mehr als zwei Komponenten verwendet werden kann.In the following, reference will be made to the case, which is particularly relevant for practice, in that exactly two components are mixed and sprayed. It is understood, however, that the invention can also be used for mixing and spraying more than two components.
Der Sprühmischer 1 umfasst ein rohrförmiges, einstückiges Mischergehäuse 2, das sich in Richtung einer Längsachse A bis zu einem distalen Ende 21 erstreckt. Mit dem distalen Ende 21 ist dabei dasjenige Ende gemeint, an welchem im Betriebszustand die durchmischten Komponenten das Mischergehäuse 2 verlassen. Dazu ist das distale Ende 21 mit einer Austrittsöffnung 22 versehen. An dem proximalen Ende, womit das Ende gemeint ist, an welchem die zu mischenden Komponenten in das Mischergehäuse 2 eingebracht werden, weist das Mischergehäuse 2 ein Verbindungsstück 23 auf, mittels welchem das Mischergehäuse 2 mit einem Vorratsbehälter für die Komponenten verbunden werden kann. Dieser Vorratsbehälter kann beispielsweise eine an sich bekannte Zwei-Komponenten-Kartusche sein, als Koaxial- oder Side-by-Side-Kartusche ausgestaltet, oder zwei Tanks, in denen die beiden Komponenten von einander getrennt aufbewahrt werden. Je nach Ausgestaltung des Vorratsbehälters, bzw. seines Ausgangs ist das Verbindungsstück ausgestaltet, z.B. als Schnappverbindung, als Bajonettverbindung, als Gewindeverbindung oder Kombinationen davon.The spray mixer 1 comprises a tubular, one-
In dem Mischergehäuse 2 ist in an sich bekannter Weise mindestens ein statisches Mischelement 3 angeordnet, das an der inneren Wand des Mischergehäuses 2 anliegt, sodass die beiden Komponenten nur durch das Mischelement 3 hindurch vom proximalen Ende zur Austrittsöffnung 22 gelangen können. Es können entweder mehrere, hintereinander angeordnete Mischelemente 3 vorgesehen sein, oder wie im vorliegenden Ausführungsbeispiel ein einstückiges Mischelement 3, das vorzugsweise spritzgegossen ist und aus einem Thermoplast besteht. Solche statischen Mischer bzw. Mischelemente 3 an sich sind dem Fachmann hinlänglich bekannt und bedürfen daher keiner weiteren Erläuterung.In the
Insbesondere geeignet sind solche Mischer bzw. Mischelemente 3 wie sie unter der Markenbezeichnung QUADRO® von der Firma Sulzer Chemtech AG (Schweiz) vertrieben werden. Derartige Mischelemente sind beispielsweise in den bereits zitierten Dokumenten
Das Mischelement 3 erstreckt sich nicht ganz bis an das distale Ende 21 des Mischergehäuses 2, sondern endet an einem Anschlag 25 (siehe
Der statische Sprühmischer 1 weist ferner eine Zerstäubungshülse 4 auf, die eine Innenfläche hat, welche das Mischergehäuse 2 in seinem Endbereich umschliesst. Die Zerstäubungshülse 4 ist einstückig ausgestaltet und vorzugsweise spritzgegossen, insbesondere aus einem Thermoplast. Sie weist einen Einlass 41 für ein unter Druck stehendes Zerstäubungsmedium auf, das insbesondere gasförmig ist. Vorzugsweise ist das Zerstäubungsmedium Druckluft. Um ein sicheres Einbringen der Druckluft in die Zerstäubungshülse 4 zu gewährleisten, weißt der Einlass 41 Fixiermittel 42 für die Zuführung der Druckluft auf, hier ein Gewinde, auf das der Anschluss eines Druckluftschlauchs aufgeschraubt werden kann. Natürlich sind auch andere Fixiermittel 42 möglich, wie beispielsweise eine Riffelung, eine Schelle, eine Klemm- oder Quetschverbindung, ein Bajonettanschluss oder ähnliches. Der Einlass 42 kann für alle bekannten Anschlüsse ausgestaltet sein, insbesondere auch für einen Luer-Lock.The static spray mixer 1 further comprises a
Um eine besonders einfache Montage bzw. Herstellung zu ermöglichen, ist die Zerstäubungshülse 4 vorzugsweise gewindefrei mit dem Mischergehäuse verbunden, beim vorliegenden Ausführungsbeispiel mittels einer Schnappverbindung. Dazu ist am Mischergehäuse 2 eine flanschartige Erhebung 24 vorgesehen (siehe
Natürlich ist auch möglich, zusätzliche Dichtmittel, beispielsweise einen O-Ring zwischen dem Mischergehäuse 2 und der Zerstäubungshülse 4 anzuordnen.Of course, it is also possible to arrange additional sealing means, for example an O-ring, between the
Alternativ zu der dargestellten Ausführung ist es auch möglich, eine Umfangsnut am Mischergehäuse 2 vorzusehen und an der Zerstäubungshülse 4 eine Erhebung, welche in diese Umfangsnut eingreift. Erfindungsgemäss sind in der Aussenfläche des Mischergehäuses 2 oder in der Innenfläche der Zerstäubungshülse 4 mehrere sich jeweils in Richtung der Längsachse A erstreckende Nuten 5 vorgesehen, durch welche das Zerstäubungsmedium vom Einlass 42 der Zerstäubungshülse 4 zum distalen Ende 21 des Mischergehäuses 2 strömen kann.Alternatively to the illustrated embodiment, it is also possible to provide a circumferential groove on the
Mit der Bezeichnung "in Richtung der Längsachse A" ist auch gemeint, dass die jeweilige Nut 5 gekrümmt, beispielsweise bogenförmig ausgestaltet sein kann. Es ist also nicht unbedingt so, dass jede der Nuten 5 geradlinig in Richtung der Längsachse A verlaufen bzw. auf die Längsachse A zu laufen muss.By the term "in the direction of the longitudinal axis A" is also meant that the
Im Folgenden wird auf den Fall Bezug genommen, dass die Nuten 5 nur in der Aussenfläche des Mischergehäuses 2 vorgesehen sind. Es versteht sich aber, dass die Nuten 5 in sinngemäss gleicher Weise alternativ oder ergänzend auch in der Innenfläche der Zerstäubungshülse 4 vorgesehen sein können.In the following reference is made to the case that the
Für die detaillierte Beschreibung der Nuten 5 und der Zerstäubungshülse 4 wird auf die
Das Mischergehäuse 2 weist einen distalen Endbereich 27 auf, der sich auf das distale Ende 21 hin verjüngt. Insbesondere ist die Aussenfläche des Mischergehäuses im distalen Endbereich 27 zumindest teilweise als Kegelstumpffläche ausgebildet. Der Konuswinkel α, den die Aussenfläche des Mischergehäuses 2 im distalen Endbereich 27 mit der Längsachse A bildet, beträgt mindestens 10° und höchstens 45°. Dieser Konuswinkel α ist im allgemeinen verschieden von und speziell kleiner als der Konuswinkel mit dem sich der Ausgangsbereich 26 im Innenraum des Mischergehäuses 2 verjüngt.The
Die Innenfläche der Zerstäubungshülse 4 ist zum Zusammenwirken mit dem distalen Endbereich 27 ausgestaltet. In dem mit K bezeichneten Bereich am distalen Ende 21 des Mischergehäuses 2 ist die Innenfläche der Zerstäubungshülse 4 ebenfalls als Kegelstumpffläche ausgestaltet, welche den gleichen Konuswinkel α aufweist wie die Aussenfläche des Mischergehäuses 2 in diesem Bereich K. In dem Bereich K liegen die Innenfläche der Zerstäubungshülse 4 und die Aussenfläche des Mischergehäuses 2 eng und dichtend aneinander an so dass in diesem Bereich K die Nuten 5 in der Aussenfläche des Mischergehäuses 2 jeweils einen separaten Strömungskanal bilden. (siehe
Stromaufwärts des Bereichs K ist die Innenfläche der Zerstäubungshülse 4 zunächst immer noch kegelstumpfförmig, hat aber einen grösseren Querschnitt als die Aussenfläche des Mischergehäuses 2, sodass zwischen der Aussenfläche des Mischergehäuses 2 und der Innenfläche der Zerstäuberhülse 4 ein Ringraum 6 existiert (siehe
Die Nuten 5, bei diesem Ausführungsbeispiel sind es acht Nuten 5, sind gleichmässig über die Aussenfläche des Mischergehäuses 2 verteilt. Es hat sich als vorteilhaft im Hinblick auf eine möglichst vollständige und homogene Zerstäubung der aus der Austrittsöffnung austretenden durchmischten Komponenten erwiesen, wenn die von den Nuten 5 erzeugten Druckluftströmungen bezüglich der radialen Richtung flach sind, also keine zu grosse Ausdehnung in der zur Längsachse A senkrechten Richtung aufweisen.The
Eine hierfür geeignete Geometrie der Nuten 5 ist insbesondere in den
Eine weitere vorteilhafte Massnahme besteht darin, wenn die Nuten 5 jeweils so ausgestaltet sind, dass ihre Tiefe T in Strömungsrichtung gesehen, also zum distalen Ende 21 hin zunimmt. Dieses Merkmal ist durch einen Vergleich der
Bezüglich der Geometrie und des Verlaufs der Nuten 5 sind natürlich noch viele andere Ausgestaltungen möglich. Die Nuten 5 können auch auf den speziellen Anwendungsfall bezogen hinsichtlich ihrer Zahl, ihres Verlaufs und ihrere Abmessungen optimiert werden.With regard to the geometry and the course of the
Eine weitere Variante besteht darin, dass sich die flanschartige Erhebung 24, die am besten in
Im Betrieb funktioniert dieses Ausführungsbeispiel wie folgt. Der statische Sprühmischer wird mittels seines Verbindungsstücks 23 mit einem Vorratsgefäss verbunden, welches die beiden Komponenten von einander getrennt enthält, beispielsweise mit einer Zwei-Komponenten-Kartusche. Der Einlass 41 der Zerstäubungshülse 4 wird mit einer Quelle für das Zerstäubungsmedium, beispielsweise einer Druckluftquelle verbunden. Nun werden die beiden Komponenten ausgetragen, gelangen in den statischen Sprühmischer 1 und werden dort mittels des Mischelements 3 innig durchmischt. Als homogen durchmischtes Material gelangen die beiden Komponenten nach Durchströmen des Mischelements 3 durch den Ausgangsbereich 26 des Mischergehäuses 2 zur Austrittsöffnung 22. Die Drucklust strömt durch den Einlass 41 der Zerstäubungshülse 4 in den Ringraum 6 zwischen der Innenfläche der Zerstäubungshülse 4 und der Aussenfläche des Mischergehäuses 2 und von dort durch die Nuten 5, die Strömungskanäle bilden, zum distalen Ende 21 und somit zur Austrittsöffnung 22 des Mischergehäuses 3. Hier treffen sie auf das durch die Austrittsöffnung 22 austretende durchmischte Material, zerstäuben es gleichmässig und transportieren es als Sprühstrahl zu dem zu behandelnden oder zu beschichtenden Substrat. Da bei einigen Anwendungen das Austragen der Komponenten aus dem Vorratsgefäss mit Druckluft bzw. druckluftunterstützt erfolgt, kann die Druckluft auch für die Zerstäubung verwendet werden.In operation, this embodiment operates as follows. The static spray mixer is connected by means of its connecting
Ein besonderer Vorteil des erfindungsgemässen statischen Sprühmischers 1 ist in seiner besonders einfachen Konstruktion und Herstellung zu sehen. Im Prinzip bedarf es bei dem hier beschriebenen Ausführungsbeispiel nur dreier Teile, nämlich eines einstückigen Mischergehäuses 2, eines einstückigen Mischelements 3 und einer einstückigen Zerstäubungshülse 4, wobei jedes dieser Teile in einfacher und wirtschaftlicher Weise mittels Spritzgiessens herstellbar ist. Die besonders einfache Konstruktion ermöglicht auch ein - zumindest weitgehend - automatisiertes Zusammensetzen der Teile des statischen Sprühmischers 1. Insbesondere sind keine Verschraubungen dieser drei Teile notwendig.A particular advantage of the inventive static spray mixer 1 can be seen in its particularly simple design and manufacture. In principle, in the embodiment described here, only three parts, namely a one-
