Description
Die vorliegende Erfindung bezieht sich auf eine Sprühvorrichtung zum Behandeln eines Hohlrauminneren, insbesondere von Hohlrauminnenwänden.The present invention relates to a spraying device for treating a cavity interior, in particular interior cavity walls.
Obwohl auf beliebige zu behandelnde Hohlrauminnenbereiche anwendbar, beispielsweise auch zur Hohlraumkonservierung von Fahrzeugen, Flugzeugen und Schiffen, werden die vorliegende Erfindung sowie die ihr zugrunde liegende Problematik in Bezug auf den Verbrennungsraum eines Motors eines Personenkraftfahrzeugs lediglich beispielhaft näher erläutert.Although applicable to any internal cavity areas to be treated, for example, for the cavity preservation of vehicles, aircraft and ships, the present invention and the underlying problems with respect to the combustion chamber of an engine of a passenger car will be explained in more detail by way of example only.
Zur Konservierung des Verbrennungsraums des Antriebsmotors, beispielsweise eines Kraftfahrzeugs, ist es bei längerer Standzeit des Fahrzeugs erforderlich, den Brennraum und zudem den an diesen angrenzenden Ventilbereich bei Viertaktmotoren bzw. die Einlass- und Auslassschlitze bei Zweitaktmotoren mittels eines Schmier- oder speziellen Konservierungsmittels zu konservieren, um eine Rostbildung auf den metallischen Oberflächen zu verhindern. Eine einfache Möglichkeit, den Brennraum zu erreichen ohne den Motor demontieren zu müssen ist der Zugang über die Zündkerzenbohrung. Durch diese Öffnung kann mit bisher aus dem Stand der Technik bekannten Sprühvorrichtungen der Brennraum nur teilweise erreicht werden. Diese Sprühvorrichtungen bestehen meist aus einem mit Druck beaufschlagten Vorratsbehälter für das Schmier- oder Konservierungsmittel, einem Betätigungsmittel und einem an diesem Betätigungsmittel fixierten Kunststoffrohr mit einer axialen Öffnung, durch die das Schmier- oder Konservierungsmittel an der gewünschten Stelle platziert wird. Im Falle des Motorbrennraums können so je nach der Länge des Kunststoffrohres die Bereiche des Brennraums direkt erreicht werden, die der Zündkerzenbohrung gegenüberliegen. Die Bereiche neben der Zündkerzenbohrung, also der obere Bereich des Brennraums mit dem Ventilbereich bei Viertaktmotoren bzw. den Einlass- und Auslassschlitzen bei Zweitaktmotoren, werden nicht oder nur undefiniert und unzureichend über den entstehenden Sprühnebel erreicht. Eine zufriedenstellende Konservierung des Brennraums ist nicht möglich.For preserving the combustion chamber of the drive motor, for example of a motor vehicle, it is necessary for longer life of the vehicle to conserve the combustion chamber and the adjoining valve region in four-stroke engines or the inlet and outlet slots in two-stroke engines by means of a lubricating or special preservative, to prevent rust on the metallic surfaces. An easy way to reach the combustion chamber without having to disassemble the engine is the access via the spark plug hole. Through this opening can be achieved only partially with previously known from the prior art spraying the combustion chamber. These spray devices usually consist of a pressurized reservoir for the lubricant or preservative agent, an actuating means and fixed to this actuating means plastic tube having an axial opening through which the lubricant or preservative on the desired location is placed. In the case of the engine combustion chamber so depending on the length of the plastic pipe, the areas of the combustion chamber can be reached directly opposite to the spark plug hole. The areas adjacent to the spark plug bore, ie the upper region of the combustion chamber with the valve region in four-stroke engines and the intake and exhaust ports in two-stroke engines are not or only undefined and achieved insufficiently via the resulting spray. A satisfactory preservation of the combustion chamber is not possible.

This object is achieved by the spray device with the features of
Accordingly, a spraying device for treating a cavity interior, in particular interior cavity walls, with a spray head having a predetermined 3-dimensional geometry and a treatment agent supply means for supplying a treatment agent to the spray head, wherein the spray head comprises a plurality of treatment agent outlet openings, which are such arranged and aligned in different spraying directions, that the 3-dimensional space in a predetermined area around the spray head can be sprayed with the treatment agent, wherein the treatment agent supply means comprises at least two portions and these portions are rotatable about the longitudinal axis of the processing agent supply means, at least one of the portions of the processing agent supply means is connected to the spray head and having an actuating means which the spray head in a rotation around the Offset longitudinal axis of the treatment agent supply means, wherein the actuating means is formed as a fixed portion with the handle and a length of the at least one portion is formed such that the spray head facing away from the end of this section protrudes from the area to be treated, the Behandlungsmittel- Outlet openings of the spray head formed as adjustable in cross-section nozzles and are selectively deactivated.
Somit weist die vorliegende Erfindung gegenüber dem Stand der Technik den Vorteil auf, dass der Sprühkopf mehrere Behandlungsmittel-Austrittsöffnungen aufweist, die in unterschiedlichen Sprührichtungen derart ausgerichtet sind, dass ein vorbestimmter 3-dimensionaler Raum vollständig besprühbar ist. Darüber hinaus wird dadurch, dass die Rotation des Sprühkopfes mittels eines Betätigungsmittels bewirkt wird, eine gleichmäßige Rotation des Sprühkopfes und damit eine auch bei kleinen versprühten Stoffmengen optimierte Verteilung des Behandlungsmittels gewährleistet. Weil der zumindest eine der wenigstens zwei Abschnitte der Behandlungsmittel-Zuführeinrichtung derart ausgebildet ist, dass das eine seiner Enden, welches von dem Sprühkopf abgewandt ist, aus dem zu behandelnden Bereich herausragt, kann die Rotation des Sprühkopfes erreicht werden, ohne dass ein Betätigungsmittel direkt am Sprühkopf selbst vorgesehen werden muss. Somit kann eine Drehung des Sprühkopfes von außerhalb des zu behandelnden Bereichs bewirkt werden. Mittels der vorgesehenen Sprühvorrichtung können also bei der Behandlung eines Hohlrauminneren sämtliche Bereiche des Hohlraums vorteilhaft erreicht werden.Thus, the present invention over the prior art has the advantage that the spray head has a plurality of treatment agent outlet openings, which are aligned in different spraying directions such that a predetermined 3-dimensional space is completely sprayable. In addition, the fact that the rotation of the spray head is effected by means of an actuating means, a uniform rotation of the spray head and thus ensures an optimized even with small quantities of sprayed substance distribution of the treatment agent. Because the at least one of the at least two sections of the treatment agent supply device is formed so that one of its ends, which faces away from the spray head, protrudes from the area to be treated, the rotation of the spray head can be achieved without an actuating means directly on Spray head itself must be provided. Thus, a rotation of the spray head from outside the area to be treated can be effected. By means of the proposed spray device Thus, in the treatment of a cavity interior, all areas of the cavity can be advantageously achieved.
In den Unteransprüchen finden sich vorteilhafte Ausgestaltungen und Verbesserungen der im Anspruch 1 angegebenen Sprühvorrichtung.In the dependent claims are advantageous embodiments and improvements of the
Gemäß einer bevorzugten Weiterbildung ist zumindest eine Behandlungsmittel-Austrittsöffnung der mehreren Behandlungsmittel-Austrittsöffnungen in Richtung und beabstandet von der Behandlungsmittel-Zuführeinrichtung ausgerichtet. Somit ist es möglich, das Behandlungsmittel auch in etwa in Richtung der Behandlungsmittel-Zuführeinrichtung zu sprühen. Dadurch werden, wenn die Sprühvorrichtung durch eine kleine Öffnung in einen Höhlraum eingeführt wird, auch die Bereiche des Hohlraums erreicht, welche angrenzend zu der Einführöffnung liegen.According to a preferred development, at least one treatment agent outlet opening of the plurality of treatment agent outlet openings is aligned in the direction of and spaced from the treatment agent supply device. Thus, it is possible to spray the treatment agent also approximately in the direction of the treatment agent supply means. Thereby, when the spray device is introduced through a small opening in a cavity, the areas of the cavity are reached, which are adjacent to the insertion opening.
Gemäß einer weiteren bevorzugten Weiterbildung weist der Sprühkopf zumindest zwei Segmente in seiner Längsrichtung auf, wobei die einzelnen Segmente bezüglich der Längsachse, der Querachse oder einer weiteren Achse des Sprühkopfs zueinander drehbar sind. Dadurch können sich die einzelnen Segmente entweder während des Sprühvorgangs für eine bessere Verteilung des Behandlungsmittels zueinander verdrehen oder ihre Winkelposition kann voreingestellt werden, um somit gezielt Bereiche des Hohlraums mit der gewünschten Menge Behandlungsmittel zu versorgen.According to a further preferred development, the spray head has at least two segments in its longitudinal direction, wherein the individual segments with respect to the longitudinal axis, the transverse axis or a further axis of the spray head are mutually rotatable. As a result, the individual segments can either rotate each other during the spraying process for a better distribution of the treatment agent or their angular position can be preset, in order thus to supply targeted areas of the cavity with the desired amount of treatment agent.
Gemäß einer weiteren bevorzugten Weiterbildung sind die Behandlungsmittel-Austrittsöffnungen zumindest eines Segments deaktivierbar. Dadurch sind bestimmte Sprührichtungen deaktivierbar, wodurch gezielt Bereiche des Hohlraums von einer direkten Beaufschlagung mit Behandlungsmittel ausgenommen sind.According to a further preferred development, the treatment agent outlet openings of at least one segment can be deactivated. As a result, certain spraying directions can be deactivated, whereby specifically areas of the cavity are excluded from a direct application of treatment agent.
Gemäß einer weiteren bevorzugten Weiterbildung ist die Behandlungsmittel-Zuführeinrichtung als mehrlumige Behandlungsmittel-Zuführeinrichtung ausgebildet. Insbesondere sind mittels einer Blockiereinrichtung, welche zur Blockierung zumindest eines Querschnitts der mehrlumigen Behandlungsmittel-Zuführeinrichtung dient, die Behandlungsmittel-Austrittsöffnungen zumindest eines Segments deaktivierbar. Durch die Blockiervorrichtung, welche beispielsweise durch ein Verdrehen der Behandlungsmittel-Zuführeinrichtung aktiviert wird, ist es möglich, bestimmte Segmente des Sprühkopfs zu deaktivieren. Beim Aktivieren der Blockiereinrichtung werden beispielsweise Schieber vor einzelne Lumen der mehrlumigen Behandlungsmittel-Zuführeinrichtung gefahren oder der Lumenquerschnitt durch ein Zusammendrücken des entsprechenden Querschnitts verschlossen.According to a further preferred development, the treatment agent supply device is designed as a multi-lumen treatment agent supply device. In particular, the treatment agent outlet openings of at least one segment can be deactivated by means of a blocking device which serves to block at least one cross section of the multi-lumen treatment agent supply device. By the blocking device, which is activated for example by a rotation of the treatment agent supply means, it is possible to deactivate certain segments of the spray head. When activating the blocking device, for example, slides are moved in front of individual lumens of the multi-lumen treatment agent supply device or the lumen cross-section is closed by compressing the corresponding cross-section.
Gemäß einer weiteren bevorzugten Weiterbildung variiert die Dichte der Verteilung der Behandlungsmittel-Austrittsöffnungen pro Flächeneinheit auf der Oberfläche des Sprühkopfs. Hierdurch werden bestimmte Bereiche des zu besprühenden 3-dimensionalen Raumes mit einer höheren oder geringeren Menge an Behandlungsmittel beaufschlagt.According to a further preferred development, the density of the distribution of the treatment agent outlet openings per unit area varies on the surface of the spray head. As a result, certain areas of the 3-dimensional space to be sprayed with a higher or lower amount of treatment agent are applied.
Gemäß einer weiteren bevorzugten Weiterbildung sind die Behandlungsmittel-Austrittsöffnungen in einem vorbestimmten Winkel und/oder senkrecht zur Oberfläche des Sprühkopfs angeordnet. Hierdurch wird eine optimale Verteilung des Behandlungsmittels in dem zu besprühenden 3-dimensionalen Raum ermöglicht.According to a further preferred development, the treatment agent outlet openings are arranged at a predetermined angle and / or perpendicular to the surface of the spray head. This allows an optimal distribution of the treatment agent in the 3-dimensional space to be sprayed.
Gemäß einer weiteren bevorzugten Weiterbildung ist der Sprühkopf aus mehreren flexiblen Leitungen ausgebildet, wobei die flexiblen Leitungen jeweils mindestens eine Behandlungsmittel-Austrittsöffnung aufweisen. Da die einzelnen Leitungen flexibel ausgebildet sind, ist die Sprührichtung der einzelnen Leitungen frei einstellbar. Die Behandlungsmittel-Austrittsöffnungen sind sowohl an den Enden als auch an den Mantelflächen der einzelnen flexiblen Leitungen angeordnet.According to a further preferred development, the spray head is formed from a plurality of flexible lines, wherein the flexible lines each have at least one treatment agent outlet opening. Because the individual lines are flexible are formed, the spray direction of the individual lines is freely adjustable. The treatment agent outlet openings are arranged both at the ends and on the lateral surfaces of the individual flexible lines.
Gemäß einer weiteren bevorzugten Weiterbildung ist der Sprühkopf und/oder die Behandlungsmittel-Zuführeinrichtung aus einem flexiblen Material ausgebildet. Durch ein flexibles Sprühkopfmaterial ist es möglich, den Sprühkopf durch Zusammendrücken des flexiblen Materials durch eine Einführöffnung in einen Hohlraum einzuführen. Die Einführöffnung kann dann einen kleineren Durchmesser aufweisen als der maximale Außendurchmesser des Sprühkopfs vor dem Zusammendrücken. Mittels Verwendung eines flexiblen Materials für die Behandlungsmittel-Zuführeinrichtung kann der Sprühkopf durch Biegungen zu dem zu behandelden Hohlraum geführt werden. Weiterhin ist die Stellung des Sprühkopfes im Raum durch Biegen der flexiblen Behandlungsmittel-Zuführeinrichtung vorab einstellbar.According to a further preferred development of the spray head and / or the treatment agent supply means is formed of a flexible material. By means of a flexible spray head material, it is possible to introduce the spray head into a cavity by compressing the flexible material through an insertion opening. The insertion opening may then have a smaller diameter than the maximum outer diameter of the spray head before compression. By using a flexible material for the treatment agent supply device, the spray head can be guided by bends to the cavity to be treated. Furthermore, the position of the spray head in space by bending the flexible treatment agent supply device is adjustable in advance.
Gemäß einer weiteren bevorzugten Weiterbildung sind die Behandlungsmittel-Austrittsöffnungen als austauschbare Wechseldüsen oder erfindungsgemäß als in ihrem Querschnitt verstellbare Düsen ausgebildet. Je nach Anwendungsfall können somit die Größe und/oder die Form des Querschnitts der Behandlungsmittel-Austrittsöffnungen variiert werden. Weiterhin ist es möglich, verstopfte Düsen auszutauschen ohne den vollständigen Sprühkopf austauschen zu müssen.According to a further preferred development, the treatment agent outlet openings are designed as replaceable alternating nozzles or according to the invention as nozzles adjustable in their cross-section. Depending on the application, the size and / or the shape of the cross section of the treatment agent outlet openings can thus be varied. Furthermore, it is possible to replace clogged nozzles without having to replace the complete spray head.
Gemäß einer weiteren bevorzugten Weiterbildung weist der Sprühkopf unterschiedlich große Behandlungsmittel-Austrittsöffnungen auf. Hierdurch kann die Durchflussmenge an Behandlungsmittel in unterschiedlichen Bereichen des Sprühkopfs eingestellt werden.According to a further preferred development, the spray head has different sized treatment agent outlet openings. As a result, the flow rate of treatment agent can be adjusted in different areas of the spray head.
Gemäß einer weiteren bevorzugten Weiterbildung ist der Sprühkopf relativ zu der Behandlungsmittel-Zuführeinrichtung, insbesondere um die Längsachse der Behandlungsmittel-Zuführeinrichtung, drehbar ausgebildet. Dadurch kann sich der Sprühkopf während des Versprühens des Behandlungsmittels im Hohlraum drehen, was eine bessere Verteilung des Behandlungsmittels ermöglicht.According to a further preferred development, the spray head is designed to be rotatable relative to the treatment agent supply device, in particular about the longitudinal axis of the treatment agent supply device. This allows the spray head during the spraying of the treatment agent in the cavity to rotate, allowing a better distribution of the treatment agent.
Gemäß einer nicht erfindungsgemäßen Weiterbildung ist das Betätigungsmittel als mechanisches, hydraulisches, pneumatisches oder elektromechanisches Betätigungsmittel ausgebildet. Hierdurch wird ein komfortables automatisiertes Drehen des Sprühkopfs während des Versprühens des Behandlungsmittels ermöglicht.According to a development not according to the invention the actuating means is designed as a mechanical, hydraulic, pneumatic or electromechanical actuating means. This allows a comfortable automated turning of the spray head during the spraying of the treatment agent.
Gemäß einer weiteren bevorzugten Weiterbildung ist zumindest eine Behandlungsmittel-Austrittsöffnung der mehreren Behandlungsmittel-Austrittsöffnungen derart zu der Längsachse der Behandlungsmittel-Zuführeinrichtung ausgerichtet, dass das aus der zumindest einen Behandlungsmittel-Austrittsöffnung ausströmende Behandlungsmittel den Sprühkopf in eine Rotation um beispielsweise die Längsachse der Behandlungsmittel-Zuführeinrichtung versetzt. Durch die Rotation des Sprühkopfs wird das Behandlungsmittel besser verteilt.According to a further preferred refinement, at least one treatment agent outlet opening of the plurality of treatment agent outlet openings is aligned with the longitudinal axis of the treatment agent supply device such that the treatment agent flowing out of the at least one treatment agent outlet opening causes the spray head to rotate about, for example, the longitudinal axis of the treatment agent supply device added. Due to the rotation of the spray head, the treatment agent is better distributed.

In den Figuren der Zeichnung bezeichnen gleiche Bezugszeichen gleiche oder funktionsgleiche Komponenten, soweit nichts Gegenteiliges angegeben ist.In the figures of the drawing, like reference characters designate like or functionally identical components, unless otherwise indicated.
Als Behandlungsmittel kommen beispielsweise Flüssigkeiten, Gase oder feine Feststoffe in Frage.Suitable treatment agents include, for example, liquids, gases or fine solids.
In die Oberfläche des Sprühkopfes 2 sind vorzugsweise mehrere Behandlungsmittel-Austrittsöffnungen 4, 5, 6 eingebracht, von denen in
Die Behandlungsmittel-Austrittsöffnungen 4, 5, 6 können als Bohrungen mit kreisförmigem Querschnitt aber auch als längliche Schlitze, rechteckförmige Durchbrüche oder ähnliches ausgeführt sein. Der Querschnitt der Behandlungsmittel-Austrittsöffnungen 4, 5, 6 ist beliebig und hängt vom Anwendungsfall und der Art des Behandlungsmittels ab. Die Behandlungsmittel-Austrittsöffnungen 4, 5, 6 können senkrecht oder in einem Winkel zur Oberfläche des ovalen Drehkörpers des Sprühkopfs 2 angebracht sein. Auf dem Sprühkopf 2 können die Behandlungsmittel-Austrittsöffnungen 4, 5, 6 gleichmäßig oder beliebig verteilt angeordnet sein, um Bereiche mit einem höheren Behandlungsmittel-Durchfluss und einem niedrigeren Behandlungsmittel-Durchfluss zu schaffen. Der Querschnitt der Behandlungsmittel-Austrittsöffnungen 4, 5, 6 kann auf der Oberfläche des Sprühkopfs variieren. So können etwa in den Bereichen, welche am weitesten von der Behandlungsmittel-Zuführeinrichtung 3 entfernt sind und in denen daher der niedrigste Druck herrscht, größere Querschnitte vorgesehen werden zum gleichmäßigen Austritt des Behandlungsmittels über die gesamte Oberfläche des Sprühkopfs. Es können auch Bereiche des Sprühkopfes 2, welche besonders wichtige Stellen des Hohlrauminneren mit Behandlungsmittel versorgen sollen, im Falle des Verbrennungsmotors sind dies bei Viertaktmotoren die Ventilbereiche im Bereich der Zündkerzenbohrung oder bei Zweitaktmotoren die Einlass- und Auslassschlitze, mit einer erhöhten Dichte an Behandlungsmittel-Austrittsöffnungen 4, 5, 6 oder vergrößerten Querschnitten der Behandlungsmittel-Austrittsöffnungen 4, 5, 6 versehen sein. Die Behandlungsmittel-Austrittsöffnungen 4, 5, 6 sind beispielsweise als wechselbare Düsen ausgebildet. Somit können die Querschnitte der Behandlungsmittel-Austrittsöffnungen 4, 5, 6 flexibel ausgewählt und verstopfte Düsen ausgetauscht werden. Die Behandlungsmittel-Austrittsöffnungen 4, 5, 6 können in ihrem Querschnitt beispielsweise einzeln, bereichsweise als auch in ihrer Gesamtheit verstellbar ausgebildet sein.The treatment
Der Sprühkopf 2 ist bevorzugt aus einem flexiblen oder schaumartigen Werkstoff, wie beispielsweise aus einem thermoplastischen Polyurethan (TPU), gebildet. Dadurch ist es möglich, den Sprühkopf 2 in zusammengedrücktem Zustand durch eine Öffnung, deren Querschnitt kleiner ist als der Querschnitt des Sprühkopfs 2 in nicht zusammengedrücktem Zustand, in den zu behandelnden Hohlraum einzuführen. Im Hohlraum entfaltet sich der Sprühkopf 2 durch die Elastizität des Materials oder durch den Druck mit dem das Behandlungsmittel zugeführt wird und das Hohlrauminnere kann wunschgemäß behandelt werden. Durch die Flexibilität des Materials des Sprühkopfs 2 kann dieser nach der Behandlung wieder durch die Zuführöffnung auf einfache Weise aus dem Hohlraum gezogen werden.The
Auch die Behandlungsmittel-Zuführeinrichtung 3 ist bevorzugt aus einem flexiblen Material gebildet. Im Gegensatz zu dem Material aus dem der Sprühkopf 2 gebildet ist, weist dieses Material jedoch vorzugsweise eine höhere Steifigkeit auf. Nach dem Biegen der Behandlungsmittel-Zuführeinrichtung 3 bleibt die Verformung erhalten. Zum einen kann der Sprühkopf 2 dann durch Biegungen eines Rohrsystems zum Behandlungsort geschoben werden. Zum anderen kann durch ein Vorbiegen der Behandlungsmittel-Zuführeinrichtung 3 die Position des Sprühkopfs 2 im Raum definiert werden. Vor dem Einführen des Sprühkopfs 2 in den zu behandelnden Hohlraum wird die Behandlungsmittel-Zuführeinrichtung 3 in der gewünschten Krümmung vorgebogen und der Sprühkopf 2 kann so innerhalb des Hohlraums hinter Hinterschnitten oder ähnlichem positioniert werden. Weiterhin kann die Behandlungsmittel-Zuführeinrichtung 3 auch aus einem Material gebildet sein, welches eine sehr geringe Steifigkeit aufweist, wie beispielsweise einem silikonartigen Material.The treatment
Der Sprühkopf 2 ist vorzugsweise entweder als integraler Bestandteil der Behandlungsmittel-Zuführeinrichtung 3, beispielsweise in Form eines Spritzguss- oder Feingussteils, oder trennbar von der Behandlungsmittel-Zuführeinrichtung 3 ausgestaltet. Im zweiten Fall ist es möglich, den Sprühkopf als Ersatzteil für die Sprühvorrichtung 1 vorzusehen. Die Düsen der Behandlungsmittel-Austrittsöffnungen 4, 5, 6 des Sprühkopfs sind ebenfalls austauschbar. Somit können verstopfte Düsen ausgetauscht werden oder Düsen mit verschiedenen Querschnitten eingesetzt werden.The
Gemäß dem vorliegenden Ausführungsbeispiel ist zumindest eine Behandlungsmittel-Austrittsöffnung 5 der mehreren Behandlungsmittel-Austrittsöffnungen 4, 5, 6 derart zu der Längsachse der Behandlungsmittel-Zuführeinrichtung 3 ausgerichtet, dass das aus der zumindest einen Behandlungsmittel-Austrittsöffnung 5 ausströmende Behandlungsmittel den Sprühkopf 2 in eine Rotation um die Längsachse der Behandlungsmittel-Zuführeinrichtung 3 versetzt. Es ist somit eine optimierte Verteilung des Behandlungsmittels möglich. Die drehbare Verbindung zwischen dem Sprühkopf 2 und der Behandlungsmittel-Zuführeinrichtung 3 ist bevorzugt dicht gegen das verwendete Behandlungsmittel ausgestaltet, etwa mittels einer Gummi- oder Keramikdichtung. Zur Lagerung der drehbaren Verbindung sind kleine Wälzlager oder Gleitlager vorgesehen, welche beispielsweise integraler Bestandteil des Sprühkopfs 2 oder der Behandlungsmittel-Zuführeinrichtung sind. In
Durch gegensätzliche Anordnung zumindest jeweils einer Behandlungsmittel-Austrittsöffnung 4, 5, 6 auf jeweils unterschiedlichen Segmenten rotieren die jeweiligen Segmente in gegensätzliche Richtungen.By opposing arrangement of at least one treatment
Die Segmente 7, 8, 9 sind zueinander bevorzugt dicht gegen das Behandlungsmittel ausgebildet. Die Abdichtung kann beispielsweise über eine Gummi- oder Keramikdichtung erfolgen. Die Segmente 7, 8, 9 sind zueinander beispielsweise über Wälz- oder Gleitlager gelagert. Die Gleitlager sind dabei bevorzugt integraler Bestandteil eines der Segmente 7, 8, 9. Die Behandlungsmittel-Zuführeinrichtung 3 kann auch derart ausgestaltet sein, dass diese mehrere Einzelleitungen aufweist, welche zu den einzelnen Segmenten führen. Dadurch ist es möglich, einzelne Segmente 7, 8, 9 des Sprühkopfs 2 abzuschalten. Das Abschalten einzelner Segmente 7, 8, 9 kann beispielsweise durch Einbringen von Schiebern in einzelne Querschnitte einer mehrlumigen Behandlungsmittel-Zuführeinrichtung 3 oder Querschnittsverringerung durch Zusammendrücken einzelner Querschnitte der mehrlumigen Behandlungsmittel-Zuführeinrichtung erfolgen. Es kann somit beispielsweise eine Verteilung des Behandlungsmittels direkt nach oben, nach unten oder zur Seite durch Deaktivierung bestimmter Segmente verhindert werden.The
Die Leitungen 10, 11, 12 sind bevorzugt aus einem flexiblen Material ausgebildet. Nach dem Verformen des Materials bleibt dieses vorzugsweise in der gewünschten Position. Durch das Verformen der einzelnen Leitungen 10, 11, 12 kann die Sprührichtung der Leitungen 10, 11, 12 eingestellt werden. Somit ist es möglich, die Sprührichtung und Sprühmenge in einer Richtung des Sprühkopfs 2 exakt zu definieren.The
Der Querschnitt der einzelnen Leitungen 10, 11, 12 wird vorzugsweise je nach Anwendungsfall und dem zu verwendenden Behandlungsmittel festgelegt. Innerhalb des Sprühkopfes 2 können Leitungen 10, 11, 12 mit verschiedenen Querschnitten und ebenso unterschiedliche Behandlungsmittel-Austrittsöffnung 4, 5, 6 verwendet werden, um unterschiedliche Durchflussmengen innerhalb des Sprühkopfs 2 zu realisieren. Die Form des Querschnitts der Leitungen 10, 11, 12 ist bevorzugt kreisförmig, kann aber auch jede Form, wie z.B. eine rechteckige Form annehmen. Wie bei den zuvor beschriebenen Ausführungsbeispielen bereits beschrieben, können die Querschnitte der Behandlungsmittel-Austrittsöffnungen 4, 5, 6 beliebig und die Behandlungsmittel-Austrittsöffnungen 4, 5, 6 als wechselbare oder als in ihrem Querschnitt verstellbare Düsen ausgebildet sein.The cross section of the
Gemäß dem vorliegenden Ausführungsbeispiel ist zumindest eine Behandlungsmittel-Austrittsöffnung 5 der mehreren Behandlungsmittel-Austrittsöffnungen 4, 5, 6 derart zu der Längsachse der Behandlungsmittel-Zuführeinrichtung 3 aus-gerichtet, dass das aus der zumindest einen Behandlungsmittel-Austrittsöffnung 5 ausströmende Behandlungsmittel den Sprühkopf 2 in eine Rotation um die Längsachse der Behandlungsmittel-Zuführeinrichtung 3 versetzt. Es ist somit eine optimierte Verteilung des Behandlungsmittels gewährleistet. Die drehbare Verbindung zwischen dem Sprühkopf 2 und der Behandlungsmittel-Zuführeinrichtung 3 ist bevorzugt dicht gegen das verwendete Behandlungsmittel ausgestaltet, etwa mittels einer Gummi- oder Keramikdichtung. Zur Lagerung der drehbaren Verbindung sind kleine Wälzlager oder Gleitlager vorgesehen, welche integraler Bestandteil des Sprühkopfs 2 oder der Behandlungsmittel-Zuführeinrichtung sein können. In
Gemäß dem vorliegenden Ausführungsbeispiel ist zumindest eine Behandlungsmittel-Austrittsöffnung 5 der mehreren Behandlungsmittel-Austrittsöffnungen 4, 5, 6 derart zu der Längsachse der Behandlungsmittel-Zuführeinrichtung 3 aus-gerichtet, dass das aus der zumindest einen Behandlungsmittel-Austrittsöffnung 5 ausströmende Behandlungsmittel den Sprühkopf 2 in eine Rotation um die Längsachse der Behandlungsmittel-Zuführeinrichtung 3 versetzt. Der Sprühkopf 2 dreht sich somit aufgrund des austretenden Behandlungsmittels relativ zu dem Abschnitt 13 der Behandlungsmittel-Zuführeinrichtung 3. Somit ist eine optimale Verteilung des Behandlungsmittels möglich. Der Sprühkopf 2 wird über das Einbringen einer Drehbewegung mittels eines Betätigungsmittels 15, welches mit dem Abschnitt 14 der Behandlungsmittel-Zuführeinrichtung 3 fest verbunden ist, rotiert. Die Länge des Abschnitts 14 ist in diesem Fall derart zu wählen, dass das dem Sprühkopf 2 abgewandte Ende des Abschnitts 14 aus dem zu behandelnden Bereich herausragt. Das Betätigungsmittel 15 ist erfindungsgemäß als Handgriff ausgebildet. Weiterhin ist es möglich, aber von der Erfindung nicht vorgesehen, den Sprühkopf über eine entsprechende mechanische, hydraulische, pneumatische oder elektromechanische Vorrichtung, beispielsweise über einen Elektromotor, welche an dem Betätigungsmittel 15 angreift, rotierbar zu gestalten. Durch das Rotieren des Sprühkopfs 2 in dem zu behandelnden Bereich wird eine optimierte Verteilung des Behandlungsmittels gewährleistet.According to the present exemplary embodiment, at least one treatment agent outlet opening 5 of the plurality of treatment
Die Verbindungshülse 17 ist bevorzugt dicht gegen das verwendete Behandlungsmittel ausgestaltet, beispielsweise mittels einer Gummi- oder Keramikdichtung. Zur Lagerung der Verbindungshülse 17 sind beispielsweise kleine Wälzlager oder Gleitlager vorgesehen, welche integraler Bestandteil eines der Abschnitte 13, 14 der Behandlungsmittel-Zuführeinrichtung 3 sind.The connecting
Obwohl die vorliegende Erfindung anhand bevorzugter Ausführungsbeispiele vollständig beschrieben wurde, ist sie darauf nicht beschränkt, sondern auf vielfältige Art und Weise modifizierbar. Insbesondere können Merkmale der einzelnen oben aufgeführten Ausführungsbeispiele beliebig miteinander kombiniert werden.Although the present invention has been fully described in terms of preferred embodiments, it is not limited thereto but is modifiable in a variety of ways. In particular, features of the individual embodiments listed above can be combined as desired.
Gemäß einer weiteren bevorzugten Weiterbildung weist der Sprühkopf eine Kameraeinrichtung zur Erfassung des Hohlrauminneren auf. Hierdurch lässt sich komfortabel der Erfolg des Einsprühens betrachten. Weiterhin kann der Hohlraum beispielsweise auch auf Schäden, wie z.B. Korrosionsschäden untersucht werden. Die erfassten Aufnahmen werden beispielsweise über eine Glasfaserleitung aus dem zu besprühenden Hohlrauminneren übertragen. Dabei kann das Glasfaserkabel beispielsweise in die Behandlungsmittel-Zuführeinrichtung integriert sein.According to a further preferred development, the spray head has a camera device for detecting the interior of the cavity. This makes it easy to look at the success of the spraying. Furthermore, the cavity may also be susceptible to damage, e.g. Corrosion damage will be investigated. The recorded images are transmitted, for example via a glass fiber cable from the cavity to be sprayed interior. In this case, the optical fiber cable can be integrated, for example, in the treatment agent supply device.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung weist der Sprühkopf eine Beleuchtungseinrichtung zur Beleuchtung des Hohlrauminneren auf. Die Beleuchtungseinrichtung ist beispielsweise als Leuchtdiode (LED) ausgebildet. Die Beleuchtungseinrichtung erleichtert die Beurteilung des Erfolges des Besprühens des Hohlrauminneren.In a further embodiment of the present invention, the spray head has a lighting device for illuminating the interior of the cavity. The lighting device is designed, for example, as a light-emitting diode (LED). The lighting device facilitates the assessment of the success of spraying the interior of the cavity.
Gemäß einer weiteren bevorzugten Weiterbildung ist der Sprühkopf als länglicher, insbesondere ovaler Rotationskörper mit einem runden Querschnitt ausgebildet. Auf der gewölbten Außenfläche des Rotationskörpers können die Behandlungsmittel-Austrittsöffnungen nahezu beliebig ausgerichtet werden.According to a further preferred development of the spray head is designed as an elongated, in particular oval body of revolution with a round cross-section. On the curved outer surface of the rotation body, the treatment agent outlet openings can be aligned almost arbitrarily.
Gemäß einer weiteren bevorzugten Weiterbildung ist der Sprühkopf als länglicher, insbesondere blockförmiger Körper mit einem ovalen, quadratischen, rechteckigen oder andersartigen Querschnitt ausgebildet. Auf der dreidimensionalen Oberfläche des Sprühkopfs können die Behandlungsmittel-Austrittsöffnungen nahezu beliebig ausgerichtet werden.According to a further preferred development of the spray head is designed as an elongated, in particular block-shaped body with an oval, square, rectangular or other cross-section. On the three-dimensional surface of the spray head, the treatment agent outlet openings can be aligned almost arbitrarily.
