Definitions

  • the invention relates to a spray mixer designed for placement and connection to a multi-component cartridge and for mixing and spraying of at least two flowable components.
  • the components to be mixed are usually supplied to such mixers from a multi-component cartridge.
  • the mixer is arranged at a cartridge outlet opening, via which the components to be mixed can be discharged from containers of the multi-component cartridge.
  • the two components are atomized at the outlet of the mixer by exposure to a pressurized medium such as compressed air and can then be applied in the form of a spray or spray on the desired substrate.
  • a pressurized medium such as compressed air
  • higher-viscosity coating media for.
  • polyurethanes, epoxy resins or the like can be processed.
  • a spray mixer for such applications is for example in the US-B-6,951,310 or the EP 2 286 925 A2 disclosed.
  • a tubular mixer housing is provided which extends in the direction of a mixer longitudinal axis from a mixer start to a distal mixer end.
  • the mixer housing houses a mixing element for static mixing.
  • a sleeve is arranged, which can be supplied via a perpendicular to the mixer longitudinal axis oriented mixer-compressed air inlet compressed air.
  • Said sleeve and the mixer housing form a mixer compressed air channel, which is closed in the direction of the mixer start and at the mixer end has an annular mixer compressed air outlet, which encloses a mixer outlet opening.
  • compressed air is supplied via the mixer compressed air inlet, which flows via the mixer compressed air channel to the mixer compressed air outlet and atomises the material emerging from the mixer outlet opening.
  • Such spray mixers are used in systems for mixing and spraying flowable components, which are used in particular for the application of coatings in the maintenance of hulls, pipelines and steel structures such as bridges. It is also necessary to coat hard to reach places. When coating such areas, it may happen that you hang with hoses or lines of the coating system, such as with the above-described compressed air hose to projections of the component to be coated. On the one hand, these hoses and lines can be damaged, which leads to failure of the coating system and thus to repair costs and delays in maintenance. On the other hand, one must The operator of the coating system must work very cautiously and thus slowly in narrow places, which can lead to a high time and thus also a cost expenditure when using the coating system.
  • a spray mixer which has a handle and a mixer outer housing in the form of a sleeve.
  • the handle and the sleeve are made of aluminum.
  • a plastic mixer which consists of a mixer inner housing and a mixing element arranged therein, can be placed on the handle.
  • the sleeve can be slipped over the mixer and bolted to the handle. Between the sleeve and the mixer inner housing, a compressed air channel is formed, can be guided by the compressed air from the handle to an outlet.
  • the mixer is intended only for single use, the sleeve is used several times.
  • the handle has connections for the flowable components and compressed air.
  • the US 4,255,125 describes a sputtering device for a combustible material with a feed for the combustible material and a further feed for a sputtering gas.
  • the combustible material and the atomizing gas are combined within the sputtering apparatus in a sputtering chamber and then passed through a mixing element in the form of curved elements.

  • a mixing inner housing arranged inside the mixer outer housing, at least one mixing element arranged in the mixer inner housing for mixing the components, and a mixer compressed air duct, which extends from a mixer compressed air inlet to a mixer outlet opening.
  • the mixer compressed air inlet is located at the mixer start.
  • the mixer compressed air channel extends from the mixer start to the mixer end along the spray mixer.
  • this is usually arranged on a multi-component cartridge and protrudes away from it.
  • the arrangement of the mixer-compressed air inlet at the mixer start no compressed air supply to the mixer end and thus no hose to the mixer end is necessary.
  • the spray mixer can be introduced into narrow spaces without the risk that a compressed air hose hooked somewhere.
  • the compressed air supply to the mixer-compressed air inlet can be made perpendicular to the mixer longitudinal axis. But it can also be inclined relative to the mixer longitudinal axis and in particular in the direction of the mixer longitudinal axis.

  • the mixer compressed air channel is formed between mixer inner housing and mixer outer housing.
  • the mixer outer housing and the mixer inner housing are thus designed so that in the assembled state between the two forms a gap which is used as a mixer-compressed air channel. This results in a particularly simple construction of the spray mixer.
  • the mixer outer housing, the mixer inner housing and the mixing element are combined in one structural unit. This is achieved by having the mixer outer housing, the mixer inner housing and the mixing element in the unmounted state, i. in their non-patched with respect to the multi-component cartridge and not connected state, are connected to each other captive.

  • the spray mixer has a mixer inlet connection which is arranged at the mixer start and which can be connected to a cartridge outlet connection of a multicomponent cartridge.
  • the mixer inlet connection has at least one mixer inlet opening, via which the components can be supplied. It also includes the mixer air inlet.
  • the spray mixer can be connected directly to the cartridge outlet connection of the multicomponent cartridge. But it is also possible that the connection takes place by means of a suitable connecting element, for example in the form of matching hoses.
  • the mixer input connection is oriented in particular in the direction of the mixer longitudinal axis. By this is meant that the components and the compressed air in the direction of the mixer longitudinal axis through the mixer input port flow. This achieves a particularly compact construction of the spray mixer.

This is no longer necessary for the compressed air supply of the spray mixer separate compressed air hose, which allows a particularly simple and safe handling of the spray mixer.
  • the mixer input connection has two separate mixer inlet openings, that is to say a separate mixer inlet opening for each component. This enables a particularly effective mixing of the two components. If more than two components are to be mixed and sprayed with the spray mixer, the mixer input connection has, in particular for each component, a separate mixer inlet opening.
  • the mixing element is designed in particular as a static mixing element.
  • a static mixer In contrast to a dynamic mixer, which has a rotating mixing element for mixing the components, a static mixer has a fixed mixing element, which allows by its special geometry efficient mixing of the components. This allows a particularly cost-effective design of the spray mixer.
  • the mixing element and the mixer input port are made in one piece.
  • the spray mixer has very few items, which makes its manufacture and its installation particularly simple and inexpensive.
  • mixing element and the mixer input port are designed as two separate components.

Description

Die Erfindung betrifft einen Sprühmischer ausgebildet zum Aufsetzen und zum Verbinden mit einer Mehrkomponentenkartusche und zum Mischen und Sprühen von mindestens zwei fliessfähigen Komponenten.The invention relates to a spray mixer designed for placement and connection to a multi-component cartridge and for mixing and spraying of at least two flowable components.

Mischer zum Mischen von mindestens zwei fliessfähigen Komponenten in Form von so genannten statischen Mischern sind beispielsweise in der EP-A-0 749 776 und in der EP A 0 815 929 beschrieben. Diese sehr kompakten Mischer liefern trotz eines einfachen, materialsparenden Aufbaus ihrer Mischerstruktur gute Mischresultate, insbesondere auch beim Mischen von hochviskosen Stoffen wie beispielsweise Dichtmassen, Zweikomponenten-Schäumen oder Zweikomponenten-Klebstoffen. Üblicherweise sind solche statischen Mischer für den Einmalgebrauch ausgelegt und werden häufig für aushärtende Produkte verwendet, bei denen die Mischer praktisch nicht mehr gereinigt werden können.Mixers for mixing at least two flowable components in the form of so-called static mixers are described, for example, in US Pat EP-A-0 749 776 and in the EP A 0 815 929 described. Despite the simple, material-saving construction of their mixer structure, these very compact mixers produce good mixing results, in particular also 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.

Die zu mischenden Komponenten werden derartigen Mischern üblicherweise von einer Mehrkomponentenkartusche zugeführt. Der Mischer wird dazu an einer Kartuschen-Austrittsöffnung angeordnet, über die die zu mischenden Komponenten aus Behältern der Mehrkomponentenkartusche ausgetragen werden können.The components to be mixed are usually supplied to such mixers from a multi-component cartridge. The mixer is arranged at a cartridge outlet opening, via which the components to be mixed can be discharged from containers of the multi-component cartridge.

Bei einigen Anwendungen, bei denen solche statischen Mischer eingesetzt werden, ist es wünschenswert, die beiden Komponenten nach ihrer Durchmischung in dem Mischer auf ein Substrat aufzusprühen. Dazu werden die durchmischten Komponenten am Ausgang des Mischers durch Beaufschlagung mit einem unter Druck stehenden Medium wie beispielsweise Druckluft zerstäubt und können dann in Form eines Sprühstrahls oder Sprühnebels auf das gewünschte Substrat aufgebracht werden. Mit dieser Technologie können insbesondere auch höher viskose Beschichtungsmedien, z. B. Polyurethane, Epoxidharze oder ähnliches verarbeitet werden.In some applications where such static mixers are used, it is desirable to spray the two components onto a substrate after they have been mixed in the mixer. For this purpose, the mixed components are atomized at the outlet of the mixer by exposure to a pressurized medium such as compressed air and can then be applied in the form of a spray or spray on the desired substrate. With this technology, especially higher-viscosity coating media, for. As polyurethanes, epoxy resins or the like can be processed.

Ein Sprühmischer für solche Anwendungen ist beispielsweise in der US-B-6,951,310 oder der EP 2 286 925 A2 offenbart. Bei dieser Vorrichtung ist ein rohrförmiges Mischergehäuse vorgesehen, das sich in Richtung einer Mischer-Längsachse von einem Mischer-Anfang bis zu einem distalen Mischer-Ende erstreckt. Das Mischergehäuse nimmt ein Mischelement für eine statische Mischung auf. An dem distalen Ende des Mischergehäuses ist eine Hülse angeordnet, der über einen senkrecht zur Mischer-Längsachse orientierten Mischer-Drucklufteingang Druckluft zugeführt werden kann. Die genannte Hülse und das Mischergehäuse bilden einen Mischer-Druckluftkanal, der in Richtung Mischer-Anfang abgeschlossen ist und am Mischer-Ende einen ringförmigen Mischer-Druckluftausgang aufweist, der eine Mischer-Austrittsöffnung umschliesst. Im Betrieb des Mischers wird über den Mischer-Drucklufteingang Druckluft zugeführt, welche über den Mischer-Druckluftkanal zum Mischer-Druckluftausgang strömt und das aus der Mischer-Austrittsöffnung austretende Material zerstäubt.A spray mixer for such applications is for example in the US-B-6,951,310 or the EP 2 286 925 A2 disclosed. In this apparatus, a tubular mixer housing is provided which extends in the direction of a mixer longitudinal axis from a mixer start to a distal mixer end. The mixer housing houses a mixing element for static mixing. At the distal end of the mixer housing a sleeve is arranged, which can be supplied via a perpendicular to the mixer longitudinal axis oriented mixer-compressed air inlet compressed air. Said sleeve and the mixer housing form a mixer compressed air channel, which is closed in the direction of the mixer start and at the mixer end has an annular mixer compressed air outlet, which encloses a mixer outlet opening. During operation of the mixer, compressed air is supplied via the mixer compressed air inlet, which flows via the mixer compressed air channel to the mixer compressed air outlet and atomises the material emerging from the mixer outlet opening.

Die Zuführung von Druckluft an den Mischer-Drucklufteingang erfolgt über einen nicht näher beschriebenen Schlauch, der wegen der genannten Orientierung des Mischer-Drucklufteingangs ebenfalls senkrecht zur Mischer-Längsachse orientiert ist.The supply of compressed air to the mixer-compressed air inlet via a hose not described in detail, which is also oriented perpendicular to the mixer longitudinal axis because of the said orientation of the mixer-compressed air inlet.

Derartige Sprühmischer werden in Systemen zum Mischen und Sprühen von fliessfähigen Komponenten verwendet, die insbesondere für das Aufbringen von Beschichtungen bei der Wartung von Schiffskörpern, Pipelines und Stahlkonstruktionen wie beispielsweise Brücken eingesetzt werden. Dabei ist es auch notwendig, schwer zugängliche Stellen zu beschichten. Bei der Beschichtung derartiger Stellen kann es dazu kommen, dass man mit Schläuchen oder Leitungen des Beschichtungssystems, wie beispielsweise mit dem oben beschriebenen Druckluftschlauch an Vorsprüngen des zu beschichtenden Bauteils hängen bleibt. Dabei können zum einen die genannten Schläuche und Leitungen beschädigt werden, was zum Ausfall des Beschichtungssystems und damit zu Reparaturkosten und Verzögerungen bei den Wartungsarbeiten führt. Zum anderen muss ein Bediener des Beschichtungssystems an engen Stellen sehr vorsichtig und damit auch langsam arbeiten, was zu einem hohen Zeit- und damit auch Kostenaufwand bei der Verwendung des Beschichtungssystems führen kann.Such spray mixers are used in systems for mixing and spraying flowable components, which are used in particular for the application of coatings in the maintenance of hulls, pipelines and steel structures such as bridges. It is also necessary to coat hard to reach places. When coating such areas, it may happen that you hang with hoses or lines of the coating system, such as with the above-described compressed air hose to projections of the component to be coated. On the one hand, these hoses and lines can be damaged, which leads to failure of the coating system and thus to repair costs and delays in maintenance. On the other hand, one must The operator of the coating system must work very cautiously and thus slowly in narrow places, which can lead to a high time and thus also a cost expenditure when using the coating system.

In der US 6,131,823 wird ein Sprühmischer beschrieben, der einen Handgriff und ein Mischeraussengehäuse in Form einer Hülse aufweist. Der Handgriff und die Hülse sind aus Aluminium hergestellt. Auf den Handgriff kann in einem ersten Arbeitsschritt ein aus Kunststoff gefertigter Mischer, der aus einem Mischerinnengehäuse und einem darin angeordneten Mischelement besteht, aufgesetzt werden. In einem zweiten Arbeitsschritt kann die Hülse über den Mischer gestülpt und mit dem Handgriff verschraubt werden. Zwischen der Hülse und dem Mischerinnengehäuse bildet sich ein Druckluftkanal aus, über den Druckluft vom Handgriff zu einem Auslass geführt werden kann. Der Mischer ist dabei nur zum einmaligen Gebrauch vorgesehen, wobei die Hülse mehrfach verwendet wird. Der Handgriff weist Anschlüsse für die fliessfähigen Komponenten und Druckluft auf.In the US 6,131,823 a spray mixer is described which has a handle and a mixer outer housing in the form of a sleeve. The handle and the sleeve are made of aluminum. In a first step, a plastic mixer, which consists of a mixer inner housing and a mixing element arranged therein, can be placed on the handle. In a second step, the sleeve can be slipped over the mixer and bolted to the handle. Between the sleeve and the mixer inner housing, a compressed air channel is formed, can be guided by the compressed air from the handle to an outlet. The mixer is intended only for single use, the sleeve is used several times. The handle has connections for the flowable components and compressed air.

Die US 4,255,125 beschreibt eine Zerstäubungsvorrichtung für einen brennbaren Stoff mit einer Zuführung für den brennbaren Stoff und einer weiteren Zuführung für ein Zerstäubungsgas. Der brennbare Stoff und das Zerstäubergas werden innerhalb der Zerstäubungsvorrichtung in einer Zerstäubungskammer zusammengeführt und anschliessend durch ein Mischelement in Form von gekrümmten Elementen geleitet.The US 4,255,125 describes a sputtering device for a combustible material with a feed for the combustible material and a further feed for a sputtering gas. The combustible material and the atomizing gas are combined within the sputtering apparatus in a sputtering chamber and then passed through a mixing element in the form of curved elements.

Demgegenüber ist es die Aufgabe der Erfindung, einen Sprühmischer zum Mischen und Sprühen von mindestens zwei fliessfähigen Komponenten vorzuschlagen, welcher einfach handhabbar ist.In contrast, it is the object of the invention to provide a spray mixer for mixing and spraying of at least two flowable components, which is easy to handle.

Erfindungsgemäss wird die Aufgabe durch einen Sprühmischer mit den Merkmalen des Anspruchs 1 gelöst.According to the invention the object is achieved by a spray mixer with the features of claim 1.

Der erfindungsgemäße Sprühmischer ist ausgebildet zum Aufsetzen auf und zum Verbinden mit einer Mehrkomponentenkartusche und zum Mischen und Sprühen von mindestens zwei fliessfähigen Komponenten und verfügt über ein rohrförmiges Mischeraussengehäuse, das sich in Richtung einer Mischer-Längsachse von einem Mischer-Anfang bis zu einem distalen Mischer-Ende erstreckt. Ausserdem weist er ein innerhalb des Mischeraussengehäuses angeordnetes Mischerinnengehäuse, mindestens ein im Mischerinnengehäuse angeordnetes Mischelement zum Durchmischen der Komponenten und einen Mischer-Druckluftkanal auf, welcher von einem Mischer-Drucklufteingang zu einer Mischer-Austrittsöffnung verläuft.The spray mixer according to the invention is designed for placement on and for connection to a multicomponent cartridge and for mixing and spraying of at least two flowable components and has a tubular mixer outer housing extending in the direction of a mixer longitudinal axis from a mixer start to a distal mixer End extends. In addition, it has a mixing inner housing arranged inside the mixer outer housing, at least one mixing element arranged in the mixer inner housing for mixing the components, and a mixer compressed air duct, which extends from a mixer compressed air inlet to a mixer outlet opening.

Der Mischer-Drucklufteingang ist am Mischer-Anfang angeordnet. Damit erstreckt sich der Mischer-Druckluftkanal vom Mischer-Anfang zum Mischer-Ende entlang des Sprühmischers. Im Betrieb des Sprühmischers ist dieser meist an einer Mehrkomponentenkartusche angeordnet und ragt von dieser weg. Durch die Anordnung des Mischer-Drucklufteingangs am Mischer-Anfang ist keine Druckluftzuführung zum Mischer-Ende und damit kein Schlauch zum Mischer-Ende notwendig. Damit kann der Sprühmischer auch in enge Zwischenräume eingeführt werden, ohne dass die Gefahr besteht, dass sich ein Druckluftschlauch irgendwo verhakt. Die Druckluftzuführung zum Mischer-Drucklufteingang kann senkrecht zur Mischer-Längsachse erfolgen. Sie kann aber auch gegenüber der Mischer-Längsachse geneigt und insbesondere in Richtung der Mischer-Längsachse erfolgen.The mixer compressed air inlet is located at the mixer start. Thus, the mixer compressed air channel extends from the mixer start to the mixer end along the spray mixer. During operation of the spray mixer, this is usually arranged on a multi-component cartridge and protrudes away from it. The arrangement of the mixer-compressed air inlet at the mixer start no compressed air supply to the mixer end and thus no hose to the mixer end is necessary. Thus, the spray mixer can be introduced into narrow spaces without the risk that a compressed air hose hooked somewhere. The compressed air supply to the mixer-compressed air inlet can be made perpendicular to the mixer longitudinal axis. But it can also be inclined relative to the mixer longitudinal axis and in particular in the direction of the mixer longitudinal axis.

Innerhalb des Mischeraussengehäuses ist ein Mischerinnengehäuse angeordnet, welches das Mischelement aufnimmt. Der Mischer-Druckluftkanal ist zwischen Mischerinnengehäuse und Mischeraussengehäuse ausgebildet. Das Mischeraussengehäuse und das Mischerinnengehäuse sind also so ausgeführt, dass sich im montierten Zustand zwischen beiden ein Zwischenraum ausbildet, der als Mischer-Druckluftkanal genutzt wird. Damit ergibt sich ein besonders einfacher Aufbau des Sprühmischers.Within the mixer outer housing, a mixer inner housing is arranged, which receives the mixing element. The mixer compressed air channel is formed between mixer inner housing and mixer outer housing. The mixer outer housing and the mixer inner housing are thus designed so that in the assembled state between the two forms a gap which is used as a mixer-compressed air channel. This results in a particularly simple construction of the spray mixer.

Erfindungsgemäss sind das Mischeraussengehäuse, das Mischerinnengehäuse und das Mischelement in einer Baueinheit zusammengefasst. Dies wird erreicht, indem das Mischeraussengehäuse, das Mischerinnengehäuse und das Mischelement im unmontierten Zustand, d.h. in ihrem in Bezug auf die Mehrkomponentenkartusche nicht aufgesetzten und nicht verbundenen Zustand, verliersicher miteinander verbunden sind.According to the invention, the mixer outer housing, the mixer inner housing and the mixing element are combined in one structural unit. This is achieved by having the mixer outer housing, the mixer inner housing and the mixing element in the unmounted state, i. in their non-patched with respect to the multi-component cartridge and not connected state, are connected to each other captive.

Dazu sind insbesondere die einzelnen Bauteile über ein Zusammenwirken von korrespondierenden Ausnehmungen bzw. Nuten und
Nasen bzw. Wulsten gegenseitig fixiert. Derartige Fixierungen werden auch als Clip- oder Click-Verbindungen bezeichnet. Insbesondere bildet der gesamte Sprühmischer eine Baueinheit, die als eine Einheit vertrieben wird. Damit ist das Aufsetzen oder Verbinden des Sprühmischers auf eine Mehrkomponentenkartusche besonders einfach, da die genannten Teile nicht zuerst zusammengesetzt werden müssen, sondern der Sprühmischer ohne vorherige Montage verwendet werden kann.For this purpose, in particular the individual components via an interaction of corresponding recesses or grooves and
Noses or beads mutually fixed. Such fixations are also referred to as clip or click connections. In particular, the entire spray mixer forms a structural unit that is distributed as a unit. Thus, the placement or connection of the spray mixer to a multi-component cartridge is particularly simple, since the said parts do not have to be assembled first, but the spray mixer can be used without previous assembly.

In Ausgestaltung der Erfindung ist der Sprühmischer dazu vorgesehen, in einem Arbeitsschritt mit einer Mehrkomponentenkartusche verbunden zu werden. Darunter ist zu verstehen, dass ohne eine vorherige Montage einzelner Bauteil mit der Mehrkomponentenkartusche verbunden werden kann.In an embodiment of the invention, the spray mixer is intended to be connected in one step with a multi-component cartridge. By this is to be understood that without a previous assembly of individual component can be connected to the multi-component cartridge.

In Ausgestaltung der Erfindung weist der Sprühmischer einen am Mischer-Anfang angeordneten Mischer-Eingangsanschluss auf, welcher an einen Kartuschen-Ausgangsanschluss einer Mehrkomponentenkartusche anschliessbar ist. Der Mischer-Eingangsanschluss verfügt über wenigstens eine Mischer-Eintrittsöffnung, über welche die Komponenten zugeführt werden können. Er umfasst ausserdem den Mischer-Drucklufteingang. Damit können über den einen Mischer-Eingangsanschluss sowohl die Verbindungen für die zu mischenden Komponenten, als auch die Verbindung für die Druckluft hergestellt werden, was eine besonders einfache Handhabung des Sprühmischers ermöglicht, da zum Anschliessen des Sprühmischers an die Mehrkomponentenkartusche nur ein Arbeitsschritt notwendig ist.In an embodiment of the invention, the spray mixer has a mixer inlet connection which is arranged at the mixer start and which can be connected to a cartridge outlet connection of a multicomponent cartridge. The mixer inlet connection has at least one mixer inlet opening, via which the components can be supplied. It also includes the mixer air inlet. Thus, both the compounds for the components to be mixed, as well as the compound for the compressed air can be produced via the one mixer input connection, which allows a particularly simple handling of the spray mixer, since only one step is necessary to connect the spray mixer to the multi-component cartridge.

Der Sprühmischer kann dabei insbesondere direkt an den Kartuschen-Ausgangsanschluss der Mehrkomponentenkartusche angeschlossen werden. Es ist aber auch möglich, dass die Verbindung mittels eines geeigneten Verbindungselements, beispielsweise in Form von passenden Schläuchen erfolgt.In particular, the spray mixer can be connected directly to the cartridge outlet connection of the multicomponent cartridge. But it is also possible that the connection takes place by means of a suitable connecting element, for example in the form of matching hoses.

Der Mischer-Eingangsanschluss ist insbesondere in Richtung der Mischer-Längsachse orientiert. Darunter ist zu verstehen, dass die Komponenten und die Druckluft in Richtung der Mischer-Längsachse durch den Mischer-Eingangsanschluss fliessen. Damit wird ein besonders kompakter Aufbau des Sprühmischers erreicht.The mixer input connection is oriented in particular in the direction of the mixer longitudinal axis. By this is meant that the components and the compressed air in the direction of the mixer longitudinal axis through the mixer input port flow. This achieves a particularly compact construction of the spray mixer.

Für diese Ausgestaltung des erfindungsgemässen Sprühmischers ist eine besonders ausgestaltete Mehrkomponentenkartusche notwendig, die einen Kartuschen-Druckluftkanal mit einem Kartuschen-Drucklufteingang und einem Kartuschen-Druckluftausgang aufweist. Damit ist für die Druckluftversorgung des Sprühmischers überhaupt kein separater Druckluftschlauch mehr notwendig, was eine besonders einfache und sichere Handhabung des Sprühmischers erlaubt.For this embodiment of the inventive spray mixer a specially designed multi-component cartridge is necessary, which has a cartridge compressed air channel with a cartridge compressed air inlet and a cartridge compressed air outlet. This is no longer necessary for the compressed air supply of the spray mixer separate compressed air hose, which allows a particularly simple and safe handling of the spray mixer.

Der Mischer-Eingangsanschluss weist insbesondere zwei getrennte Mischer-Eintrittsöffnungen, also für jede Komponente eine separate Mischer-Eingangsöffnung auf. Damit wird eine besonders effektive Durchmischung der beiden Komponenten ermöglicht. Falls mit dem Sprühmischer mehr als zwei Komponenten gemischt und versprüht werden sollen, weist der Mischer-Eingangsanschluss insbesondere für jede Komponente eine separate Mischer-Eintrittsöffnung auf.In particular, the mixer input connection has two separate mixer inlet openings, that is to say a separate mixer inlet opening for each component. This enables a particularly effective mixing of the two components. If more than two components are to be mixed and sprayed with the spray mixer, the mixer input connection has, in particular for each component, a separate mixer inlet opening.

Das Mischelement ist insbesondere als ein statisches Mischelement ausgeführt. Im Gegensatz zu einem dynamischen Mischer, welcher ein rotierendes Mischelement zum Mischen der Komponenten aufweist, verfügt ein statischer Mischer über ein fest stehendes Mischelement, welches durch seine spezielle Geometrie eine effiziente Mischung der Komponenten ermöglicht. Dies ermöglicht einen besonders kostengünstigen Aufbau des Sprühmischers.The mixing element is designed in particular as a static mixing element. In contrast to a dynamic mixer, which has a rotating mixing element for mixing the components, a static mixer has a fixed mixing element, which allows by its special geometry efficient mixing of the components. This allows a particularly cost-effective design of the spray mixer.

In Ausgestaltung der Erfindung sind das Mischelement und der Mischer-Eingangsanschluss einstückig ausgeführt. Damit weist der Sprühmischer besonders wenige Einzelteile auf, was seine Herstellung und seine Montage besonders einfach und kostengünstig macht.In an embodiment of the invention, the mixing element and the mixer input port are made in one piece. Thus, the spray mixer has very few items, which makes its manufacture and its installation particularly simple and inexpensive.

Es ist aber auch möglich, dass das Mischelement und der Mischer-Eingangsanschluss als zwei getrennte Bauteile ausgeführt sind.But it is also possible that the mixing element and the mixer input port are designed as two separate components.

In Ausgestaltung der Erfindung sind das Mischeraussengehäuse, das Mischerinnengehäuse und das Mischelement aus Kunststoff ausgeführt. Damit weist der Sprühmischer ein besonders geringes Gewicht auf und ist ausserdem kostengünstig herzustellen. Die Bauteile können beispielsweise aus Polypropylen, Polyamid, Polycaprolactam (Polyamid 6) oder Polybutylenterephthalat bestehen. Es sind aber auch andere geeignete Kunststoffe möglich.In an embodiment of the invention, the mixer outer housing, the mixer inner housing and the mixing element are made of plastic. Thus, the spray mixer has a particularly low weight and is also inexpensive to manufacture. The components may for example consist of polypropylene, polyamide, polycaprolactam (polyamide 6) or polybutylene terephthalate. But there are also other suitable plastics possible.

Die Herstellung des Mischeraussengehäuses, des Mischerinnengehäuses und des Mischelements erfolgt insbesondere mittels eines Spritzgussverfahrens. Die Bauteile können damit einfach in sehr grossen Stückzahlen und besonders kostengünstig hergestellt werden.The preparation of the mixer outer housing, the mixer inner housing and the mixing element takes place in particular by means of an injection molding process. The components can thus be easily manufactured in very large numbers and particularly cost.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich anhand der nachfolgenden Beschreibung von Ausführungsbeispielen sowie anhand der Zeichnungen, in welchen gleiche oder funktionsgleiche Elemente mit identischen Bezugszeichen versehen sind.Further advantages, features and details of the invention will become apparent from the following description of exemplary embodiments and with reference to the drawings, in which the same or functionally identical elements are provided with identical reference numerals.

Gemäss Fig. 1 weist eine Mehrkomponentenkartusche 10 einen ersten Behälter 11 zur Aufnahme einer ersten Komponente und einen zweiten Behälter 12 zur Aufnahme einer zweiten Komponente auf. Der erste und der zweite Behälter 11, 12 haben eine zylinderförmige Grundform mit einer ersten Zylinderachse 13 und einer zweiten Zylinderachse 14. Die beiden Behälter 11, 12 sind achsparallel nebeneinander angeordnet. Die Behälter 11, 12 sind miteinander verbunden und weisen einen minimalen Abstand zueinander auf. Damit ergibt sich zwischen den beiden Behältern eine Kerbe 15, die parallel zu den beiden Zylinderachsen 13, 14 verläuft. Die Mehrkomponentenkartusche 10 ist damit als eine so genannte Side-by-Side-Kartusche ausgeführt. Die Behälter 11, 12 der Mehrkomponentenkartusche 10 weisen einen selben Durchmesser auf. Ein Mischungsverhältnis der Komponenten beim Austragen aus den Behältern 11, 12 beträgt damit 1:1. Es sind aber auch andere Durchmesser- und damit Mischungsverhältnisse, wie beispielsweise 1:2, 1:4, 1:10 oder höher möglich.According to Fig. 1 For example, a multi-component cartridge 10 has a first container 11 for receiving a first component and a second container 12 for receiving a second component. The first and the second container 11, 12 have a cylindrical basic shape with a first cylinder axis 13 and a second cylinder axis 14. The two containers 11, 12 are arranged side by side parallel to the axis. The containers 11, 12 are connected to each other and have a minimum distance from each other. This results in a notch 15 between the two containers, which extends parallel to the two cylinder axes 13, 14. The multi-component cartridge 10 is thus designed as a so-called side-by-side cartridge. The containers 11, 12 of the multi-component cartridge 10 have a same diameter. A mixing ratio of the components when discharging from the containers 11, 12 is thus 1: 1. But there are also other diameter and thus mixing ratios, such as 1: 2, 1: 4, 1:10 or higher possible.

An einer Stirnseite der Behälter 11, 12 weisen diese jeweils eine Füllöffnung 16, 17 auf, die sich über die gesamte Stirnseite der Behälter 11, 12 erstreckt. Über die Füllöffnungen 16, 17 können die Behälter 11, 12 mit einer entsprechenden fliessfähigen Komponente befüllt werden. Die Füllöffnungen 16, 17 sind in der Darstellung der Fig. 1 mit jeweils einem Kolben 18, 19 verschlossen. Die Kolben 18, 19 werden nach dem Befüllen der Behälter 11, 12 eingesetzt. Durch Verschieben der Kolben 18, 19 von den Füllöffnungen 16, 17 weg können die Komponenten über zwei Kartuschen-Austrittsöffnungen, die auf einer den Füllöffnungen 16, 17 gegenüber liegenden Seite der Mehrkomponentenkartusche 10 angeordnet sind, ausgetragen werden. Die Kartuschen-Austrittsöffnungen sind in der Darstellung der Fig. 1 nicht zu sehen.At one end face of the containers 11, 12, these each have a filling opening 16, 17, which extends over the entire end face of the containers 11, 12. Via the filling openings 16, 17, the containers 11, 12 can be filled with a corresponding flowable component. The filling openings 16, 17 are in the illustration of Fig. 1 each with a piston 18, 19 closed. The pistons 18, 19 are used after filling the containers 11, 12. By moving the pistons 18, 19 away from the filling openings 16, 17, the components can be discharged via two cartridge outlet openings, which are arranged on a side of the multicomponent cartridge 10 opposite the filling openings 16, 17. The cartridge outlet openings are in the illustration of Fig. 1 not to be seen.

In der Kerbe 15 zwischen den beiden Behältern 11, 12 verläuft ein Kartuschen-Druckluftkanal 20. Der Kartuschen-Druckluftkanal 20 weist einen kreisrunden Querschnitt auf und verläuft von einem Kartuschen-Drucklufteingang 21 zu einem in der Fig. 1 nicht dargestellten Kartuschen-Druckluftausgang. Der Kartuschen-Drucklufteingang 21 ist in einer Ebene mit den Füllöffnungen 16, 17 der Behälter 11, 12 angeordnet. Der Kartuschen-Druckluftausgang befindet sich im Bereich der Kartuschen-Austrittsöffnungen. Der Kartuschen-Druckluftkanal 20 verläuft damit über die gesamte Länge der Behälter 11, 12 und damit auch der Mehrkomponentenkartusche 10.In the notch 15 between the two containers 11, 12 extends a cartridge compressed air passage 20. The cartridge compressed air passage 20 has a circular cross section and extends from a cartridge compressed air inlet 21 to one in the Fig. 1 not shown cartridge compressed air outlet. The cartridge compressed air inlet 21 is arranged in a plane with the filling openings 16, 17 of the containers 11, 12. The cartridge compressed air outlet is located in the area of the cartridge outlet openings. The cartridge compressed air channel 20 thus extends over the entire length of the container 11, 12 and thus also the multi-component cartridge 10th

Der erste Behälter 11, der zweite Behälter 12 und der Druckluftkanal 20 sind einstückig ausgeführt. Ausserdem sind für die nicht dargestellten Kartuschen-Austrittsöffnungen und den Kartuschen-Druckluftausgang ebenfalls keine separaten Bauteile notwendig, so dass damit die gesamte Mehrkomponentenkartusche 10 einstückig ausgeführt ist. Die Mehrkomponentenkartusche 10 wird mittels eines Spritzgussverfahrens aus Kunststoff hergestellt. Dazu kann beispielsweise Polypropylen, Polyamid, Polycaprolactam (Polyamid 6) oder Polybutylenterephthalat verwendet werden.The first container 11, the second container 12 and the compressed air channel 20 are made in one piece. In addition, no separate components are necessary for the cartridge outlet openings and the cartridge compressed air outlet, not shown, so that the entire multi-component cartridge 10 is made in one piece. The multi-component cartridge 10 is made of plastic by an injection molding method. For example, polypropylene, polyamide, polycaprolactam (polyamide 6) or polybutylene terephthalate can be used for this purpose.

Auf der den Füllöffnungen 16, 17 gegenüber liegenden Seite der Mehrkomponentenkartusche 10 ist ein Sprühmischer 22 angeordnet.

Der Sprühmischer 22 zum Mischen und Sprühen von mindestens zwei fliessfähigen Komponenten ist in der Fig. 2 in einer Schnittdarstellung dargestellt. Der Schnitt verläuft bezüglich der Fig. 1 zwischen den beiden Behältern 11, 12 parallel zu den Zylinderachsen 13, 14. In der Fig. 2 ist ausserdem noch ein kleiner Teil der Mehrkomponentenkartusche 10 dargestellt. Ein Teil des Behälters 11 der Mehrkomponentenkartusche 10, der hinter der Schnitteebene liegt, ist zum besseren Verständnis gepunktet dargestellt.The spray mixer 22 for mixing and spraying of at least two flowable components is disclosed in U.S. Patent Nos. 5,496,074 Fig. 2 shown in a sectional view. The section runs with respect to the Fig. 1 between the two containers 11, 12 parallel to the cylinder axes 13, 14. In the Fig. 2 Furthermore, a small part of the multicomponent cartridge 10 is shown. A part of the container 11 of the multicomponent cartridge 10, which lies behind the cutting plane, is shown dotted for better understanding.

Der Sprühmischer 22 verfügt über ein hauptsächlich rohrförmiges Mischeraussengehäuse 23, das sich in Richtung einer Mischer-Längsachse 24 von einem Mischer-Anfang 25 bis zu einem distalen Mischer-Ende 26 erstreckt. Am Mischer-Anfang 25 ist der Sprühmischer 22 mit der Mehrkomponentenkartusche 10 verbunden.The spray mixer 22 has a generally tubular mixer outer housing 23 which extends in the direction of a mixer longitudinal axis 24 from a mixer start 25 to a distal mixer end 26. At the mixer start 25, the spray mixer 22 is connected to the multi-component cartridge 10.

Das Mischeraussengehäuse 23 weist in einem mittleren Bereich einen konstanten Querschnitt auf und verjüngt sich ein wenig zum Mischer-Ende 26 hin. Auf der gegenüberliegenden Seite zum Mischer-Anfang 25 weitet sich das Mischeraussengehäuse 23 auf und bildet einen Teil eines Mischer-Eingangsanschlusses 27, mittels welchem der Sprühmischer 22 an einen Kartuschen-Ausgangsanschluss 28 der Mehrkomponentenkartusche 10 angeschlossen ist.The mixer outer housing 23 has a constant cross section in a central region and tapers slightly towards the mixer end 26. On the opposite side to the mixer start 25, the mixer outer housing 23 widens and forms part of a mixer input port 27, by means of which the spray mixer 22 is connected to a cartridge outlet port 28 of the multi-component cartridge 10.

Innerhalb des Mischeraussengehäuses 23 ist ein Mischerinnengehäuse 29 angeordnet, welches eine der Kontur des Mischeraussengehäuses 23 korrespondierende Aussenkontur aufweist, so dass sich zwischen dem Mischeraussengehäuse 23 und dem Mischerinnengehäuse 29 ein ringförmiger Hohlraum ergibt, der als ein Mischer-Druckluftkanal 30 dient. Dem Mischer-Druckluftkanal 30 kann über einen Mischer-Drucklufteingang 31, der ebenfalls einen Teil des Mischer-Eingangsanschlusses 27 bildet, Druckluft zugeführt werden. Der Mischer-Drucklufteingang 31 ist damit am Mischer-Anfang 25 angeordnet. Die Druckluft wird über den Mischer-Druckluftkanal 30 zu einem Mischer-Druckluftausgang 32 geleitet, der sich am Mischer-Ende 26 befindet.Within the mixer outer housing 23, a mixer inner housing 29 is arranged, which has an outer contour corresponding to the contour of the mixer outer housing 23, so that between the mixer outer housing 23 and the mixer inner housing 29, an annular cavity results, which serves as a mixer compressed air channel 30. The mixer compressed air channel 30 can be fed via a mixer-compressed air inlet 31, which also forms part of the mixer input port 27, compressed air. The mixer-compressed air inlet 31 is thus arranged at the mixer start 25. The compressed air is conducted via the mixer compressed air channel 30 to a mixer compressed air outlet 32, which is located at the mixer end 26.

Innerhalb des Mischerinnengehäuses 29 ist ein statisches Mischelement 33 angeordnet, das zum Mischen der beiden Komponenten dient. Das Mischelement 33 ist einstückig mit einer Mischer-Eintrittsöffnung 34 ausgeführt, über welche eine erste Komponente dem Sprühmischer 22 zugeführt werden kann. Das Mischelement 33 weist noch eine zweite Mischer-Eintrittsöffnung auf, über die eine zweite Komponente zugeführt werden kann. Diese liegt aber nicht in der dargestellten Schnittebene, weshalb diese zweite Mischer-Eintrittsöffnung in der Fig. 2 nicht dargestellt ist. Die Mischer-Eintrittsöffnung 34 weist einen kreisrunden Querschnitt auf und bildet ebenfalls einen Teil des Mischer-Eingangsanschlusses 27.Within the mixer inner housing 29, a static mixing element 33 is arranged, which serves for mixing of the two components. The mixing element 33 is designed in one piece with a mixer inlet opening 34, via which a first component can be supplied to the spray mixer 22. The mixing element 33 also has a second mixer inlet opening, via which a second component can be supplied. However, this is not in the illustrated section plane, why this second mixer inlet opening in the Fig. 2 not shown. The mixer inlet 34 has a circular cross section and also forms part of the mixer input port 27th

Die beiden Mischer-Eintrittsöffnungen sind mit korrespondierenden Kartuschen-Austrittsöffnungen verbunden, wobei in der Fig. 2 nur eine Kartuschen-Austrittsöffnung 36 zu sehen ist, die mit der Mischer-Eintrittsöffnung 34 verbunden ist. Die Kartuschen-Austrittsöffnung 36 ist Teil des Kartuschen-Ausgangsanschlusses 28.The two mixer inlet openings are connected to corresponding cartridge outlet openings, wherein in the Fig. 2 only a cartridge outlet opening 36 is seen, which is connected to the mixer inlet opening 34. The cartridge exit port 36 is part of the cartridge exit port 28.

Am Mischer-Ende 26 weist das Mischerinnengehäuse 29 eine Mischer-Austrittsöffnung 35 auf, über welche die durch das Mischelement 33 gemischten Komponenten das Mischerinnengehäuse 29 verlassen können. Der Mischer-Druckluftausgang 32 ist um die Mischer-Austrittsöffnung 35 herum angeordnet. Damit werden die aus der Mischer-Austrittsöffnung 35 austretenden gemischten Komponenten vernebelt und versprüht. Im Bereich der Mischer-Austrittsöffnung 35 und des Mischer-Druckluftausgangs 32 können auch zusätzlich Nuten oder ähnliches angeordnet sein, die für eine Verwirbelung der Druckluft und damit zu einer effektiven Vernebelung der gemischten Komponenten sorgen.At the mixer end 26, the mixer inner housing 29 has a mixer outlet opening 35, via which the components mixed by the mixing element 33 can leave the mixer inner housing 29. The mixer compressed air outlet 32 is arranged around the mixer outlet opening 35. Thus, the mixed components exiting the mixer outlet 35 are atomized and sprayed. In the region of the mixer outlet opening 35 and the mixer compressed air outlet 32, grooves or the like can additionally be arranged, which provide for a swirling of the compressed air and thus to an effective atomization of the mixed components.

Der Mischer-Drucklufteingang 31 ist mit einem Kartuschen-Druckluftausgang 37 der Mehrkomponentenkartusche 10 verbunden, welcher vom Kartuschen-Druckluftkanal 20 mit Druckluft versorgt. Der Kartuschen-Druckluftkanal 20 knickt dazu in Richtung Mischer-Längsachse 24 ab. Der Mischer-Drucklufteingang 31 und der Kartuschen-Druckluftausgang 37 weisen einen ringförmigen Querschnitt auf und sind um die Mischer-Eintrittsöffnungen 34 und Kartuschen-Austrittsöffnungen 36 angeordnet. Der Mischer-Drucklufteingang 31 ist dabei ein Teil des Mischer-Eingangsanschlusses 27 und der Kartuschen-Druckluftausgang 37 ein Teil des Kartuschen-Ausgangsanschlusses 28.The mixer compressed air inlet 31 is connected to a cartridge compressed air outlet 37 of the multicomponent cartridge 10, which supplies compressed air from the cartridge compressed air channel 20.

The mixer compressed air inlet 31 and the cartridge compressed air outlet 37 have an annular cross section and are arranged around the mixer inlet openings 34 and the cartridge outlet openings 36. The mixer compressed air inlet 31 is a part of the mixer input port 27 and the cartridge compressed air outlet 37 is a part of the cartridge output port 28.

Die Komponenten und die Druckluft strömen vom Kartuschen-Ausgangsanschluss 28 zum Mischer-Eingangsanschluss 27 entlang der Mischer-Längsachse 24. Sie sind damit in Richtung der Mischer-Längsachse 24 orientiert.The components and the compressed air flow from the cartridge outlet port 28 to the mixer inlet port 27 along the mixer longitudinal axis 24. They are thus oriented in the direction of the mixer longitudinal axis 24.

Die Verbindung zwischen dem Mischer-Eingangsanschluss 27 und dem Kartuschen-Ausgangsanschluss 28 wird durch eine Überwurfmutter 38 gesichert, die um den Mischer-Drucklufteingang 31 und den Kartuschen-Druckluftausgang 37 herum angeordnet ist. Statt der Überwurfmutter sind auch andere Sicherungen, wie beispielsweise ein Bajonett-Verschluss möglich.The connection between the mixer inlet port 27 and the cartridge outlet port 28 is secured by a union nut 38 disposed about the mixer compressed air inlet 31 and the cartridge compressed air outlet 37. Instead of the union nut other fuses, such as a bayonet lock are possible.

Das Mischeraussengehäuse 23, das Mischerinnengehäuse 29 und das Mischelement 33 sind über an sich bekannte, nicht näher dargestellte Click-Verbindungen miteinander verbunden und sind so in einer Baueinheit zusammengefasst. Darüber hinaus ist der Mischer-Eingangsanschluss 27 und die Überwurfmutter 38 verliersicher mit den anderen Bauteilen verbunden, so dass der gesamte Sprühmischer 22 eine Baueinheit bildet.The mixer outer housing 23, the mixer inner housing 29 and the mixing element 33 are connected to each other via known per se, not shown click connections and are combined in one unit. In addition, the mixer input port 27 and the union nut 38 is captively connected to the other components, so that the entire spray mixer 22 forms a structural unit.

Für die Verbindung des Sprühmischers 22 mit der Mehrkomponentenkartusche 10 wird der Sprühmischer 22 auf die Mehrkomponentenkartusche 10 aufgesetzt und anschliessend die Verbindung mit der Überwurfmutter 38 gesichert. Das Aufsetzen und Sichern wird dabei als ein Arbeitsschritt angesehen.For the connection of the spray mixer 22 with the multi-component cartridge 10, the spray mixer 22 is placed on the multi-component cartridge 10 and then secured the connection with the union nut 38. Setting up and saving is considered as one step in this process.

Die einzelnen Bauteile des Sprühmischers 22 werden mittels eines Spritzgussverfahrens aus Kunststoff hergestellt. Dazu kann beispielsweise ebenfalls Polypropylen, Polyamid, Polycaprolactam (Polyamid 6) oder Polybutylenterephthalat verwendet werden.The individual components of the spray mixer 22 are made of plastic by means of an injection molding process. For example, polypropylene, polyamide, polycaprolactam (polyamide 6) or polybutylene terephthalate can also be used for this purpose.
