Es ist daher die Aufgabe der vorliegenden Erfindung, eine Düsenvorrichtung zur Verfügung zu stellen, die mit einer flexibleren Anordnung durch ein gutes Reinigungsergebnis bei reduziertem Wasserverbrauch die Effizienz von HD-Spritzrohren weiter steigert.It is therefore an object of the present invention to provide a nozzle device is available, which further increases the efficiency of HD spray tubes with a more flexible arrangement by a good cleaning result with reduced water consumption.
Diese Aufgabe wird gelöst durch eine Düsenvorrichtung der eingangs genannten Art, bei welcher an dem Düsenkörper wenigstens ein weiteres Düsenelement vorgesehen ist, welches jeweils in einem von dem ersten Düsenkanal verschiedenen weiteren Düsenkanal oder zusammen mit dem ersten und/oder einem weiteren Düsenelement in einem gemeinsamen Düsenkanal angeordnet ist und dass der Düsenkörper an der Düsenvorrichtung um seine Längsachse ohne axialen Versatz drehbar angeordnet ist.This object is achieved by a nozzle device of the type mentioned, in which at least one further nozzle element is provided on the nozzle body, which in each case in a different of the first nozzle channel further nozzle channel or together with the first and / or another nozzle member in a common nozzle channel is arranged and that the nozzle body is rotatably mounted on the nozzle device about its longitudinal axis without axial displacement.
Da an einer Düsenvorrichtung mehrere Düsenkanäle und/oder Düsenelemente vorgesehen sind, können diese mit einem geringeren Durchmesser versehen werden, was zum einen den Volumenstrom selbst reduziert, zwei Düsenelemente verbrauchen etwa 60% des Volumens eines Düsenelements, dessen Durchmesser der Summe der zwei Düsenelemente entspricht, bei drei Strahlen mit 40% des Durchmessers eines größeren Strahls ist eine Reduktion des Volumenstroms auf die Hälfte festzustellen.Since a plurality of nozzle channels and / or nozzle elements are provided on a nozzle device, these can be provided with a smaller diameter, which on the one hand reduces the volume flow itself, two nozzle elements consume about 60% of the volume of a nozzle element whose diameter corresponds to the sum of the two nozzle elements, for three beams with 40% of the diameter of a larger jet, a reduction of the volume flow to half is observed.
Überdies ist der Wasserbrauch auch deshalb reduziert, weil der Düsenkörper durch seine Drehbarkeit um die Längsachse hinsichtlich der Laufrichtung der Papiermaschine optimal justierbar ist, und so eine deutliche Optimierung der Einstellung erreicht werden kann. Der Düsenkörper ist hierbei prinzipiell drehbar, während des Betriebs der Düsenvorrichtung aber drehfest.Moreover, the water consumption is also reduced because the nozzle body is optimally adjustable by its rotation about the longitudinal axis with respect to the direction of the paper machine, and so a significant optimization of the setting can be achieved. The nozzle body is in principle rotatable during operation of the nozzle device but rotatable.
Hinsichtlich der Anordnung von Düsenkanälen und Düsenelementen an der erfindungsgemäßen Düsenvorrichtung sind verschiedene Ausführungsformen denkbar, die unterschiedliche Weiterbildungen der Erfindung darstellen. Bei einer von diesen kann etwa der drehbare Düsenkörper mit zwei oder drei Düsenelementen versehen sein, denen jeweils ein eigener Düsenkanal zugeordnet ist oder die einem gemeinsamen Düsenkanal zugeordnet sind.With regard to the arrangement of nozzle channels and nozzle elements on the nozzle device according to the invention, various embodiments are conceivable that represent different developments of the invention. In one of these, for example, the rotatable nozzle body may be provided with two or three nozzle elements, which each have their own nozzle channel is assigned or assigned to a common nozzle channel.
Bei einer weiteren Ausbildung der Düsenvorrichtung kann der Düsenkörper einen im wesentlichen kreisrunden Querschnitt aufweisen und können die Düsenkanäle und/oder Düsenelemente auf einer den Kreismittelpunkt schneidenden Geraden angeordnet sein, beispielsweise in einer bezügliche des Kreismittelpunkts symmetrischen Konfiguration, die eine einfache Einstellung der Vorrichtungen im Verhältnis zueinander an verschiedenen Austrittsöffnungen gestattet.In a further embodiment of the nozzle device, the nozzle body may have a substantially circular cross-section and the nozzle channels and / or nozzle elements may be arranged on a line intersecting the center of the circle, for example in a symmetrical relative to the circle center configuration, the simple adjustment of the devices in relation to each other allowed at different outlet openings.
Bei einer weiteren Ausführung der Düsenvorrichtung können wenigstens zwei Düsenkanäle und/oder Düsenelemente im Düsenkörper mit gleichem Abstand zu verschiedenen Seiten des Kreismittelpunkts angeordnet sein und es kann bei einer ungeraden Anzahl von Düsenkanälen und/oder Düsenelementen eines von diesen im Kreismittelpunkt liegen. Verläuft beispielsweise die Gerade, auf der die Düsenelemente angeordnet sind, ihrer Justierung nach in Richtung der x-Achse der Papiermaschine, kann eine den Düsenkanälen und/oder Düsenelementen entsprechende Anzahl hinter einander liegender Strahle erreicht werden.In a further embodiment of the nozzle device, at least two nozzle channels and / or nozzle elements may be arranged in the nozzle body at the same distance to different sides of the circle center and it may be in the center of an odd number of nozzle channels and / or nozzle elements of these. If, for example, the straight line on which the nozzle elements are arranged extends in the direction of the x-axis of the paper machine, a number of behind-the-jet beams corresponding to the nozzle channels and / or nozzle elements can be achieved.
Ähnlich vorteilhaft kann durch die Anordnung der Düsenelemente ihrer Justierung nach quer zur x-Achse gegebenenfalls ein breiterer Bereich von nur einer Düsenvorrichtung bestrichen werden, was die Reinigungsintensität des Spritzrohres erhöhen kann.Similarly advantageous may be by the arrangement of the nozzle elements of their adjustment to transverse to the x-axis optionally one wider area of only one nozzle device are coated, which can increase the cleaning intensity of the spray tube.
Bei anderen vorteilhaften Weiterbildungen der erfindungsgemäßen Düsenvorrichtung können die Längsachsen der Düsenkanäle und/oder Düsenelemente den gleichen oder jeweils verschiedene Winkel mit der Längsachse des Düsenkörpers einschließen.In other advantageous developments of the nozzle device according to the invention, the longitudinal axes of the nozzle channels and / or nozzle elements may include the same or different angles with the longitudinal axis of the nozzle body.
Bei anderen vorteilhaften Weiterbildungen der erfindungsgemäßen Düsenvorrichtung kann zumindest eine Mehrzahl von Düsenkanälen und/oder Düsenelementen jeweils untereinander den gleichen oder jeweils verschiedene Kanaldurchmesser aufweisen.In other advantageous developments of the nozzle device according to the invention, at least a plurality of nozzle channels and / or nozzle elements may each have the same or different channel diameters.
Weist eine erfindungsgemäße Düsenvorrichtung etwa zwei Düsenelemente und gegebenenfalls die gleiche Anzahl von Düsenkanälen auf, kann sie zwei parallele oder in einem Winkel zueinander befindliche Wasserstrahle abgeben, und sie erzielt damit eine höhere Reinigungs- bzw. Konditionierleistung an Sieben, Filzen und Walzen einer Papiermaschine, als Düsenvorrichtungen mit nur einem Düsenelement. Die Position der Wasserstrahle kann sowohl so eingestellt werden, dass sie sich in x-Richtung hintereinander befinden, als auch nebeneinander, mit jeder Stellung zwischen diesen beiden Positionen. Durch diese Manipulationsmöglichkeiten ist es möglich, bei Anordnung der Strahle quer zur x-Achse der Maschine die Gesamtzahl der Strahle, die das Spritzrohr abgibt, zu verdoppeln, was eine Erhöhung der Reinigungs- bzw. Konditionierleistung des Spritzrohres zur Folge hat, wobei außerdem die Strahle in einem Winkel zur z-Achse austreten können, was eine Erhöhung der Reinigungs- bzw. Konditionierleistung des Spritzrohres und eine gründlichere Reinigung von doppellagigen Blattbildungssieben zur Folge hat. Bei Anordnung der Strahle in der x-Achse kann eine Erhöhung der Reinigungs- bzw. Konditionierleistung jeder einzelnen Düse erzielt werden. Bei Anordnung der Strahle in der x-Achse oder quer zur x-Achse kann durch den Einsatz kleinerer Düsenelemente und entsprechend reduzierter Strahldurchmesser bspw. bei verdoppelung der Anzahl der Strahle eine adäquate Reinigungs- bzw. Konditionierleistung der Düse bei einem signifikant reduzierten Wasserverbrauch erzielt werden, wobei etwa, wie bereits erwähnt, der Volumenstrom von zwei Strahlen mit einem Durchmesser von 0,5 mm bei gleichem Wasserdruck nur etwa 60% des Volumenstroms eines Strahls von 1,0 mm Durchmesser entspricht.If a nozzle device according to the invention has approximately two nozzle elements and optionally the same number of nozzle channels, it can emit two parallel or at an angle to each other water jet, and thus achieves a higher cleaning or conditioning performance on screening, felting and rolling a paper machine, as Nozzle devices with only one nozzle element. The position of the waterbeams can be set both to be in the x-direction one behind the other, as well as next to each other, with each position between these two positions. These manipulation possibilities make it possible, when the jet is arranged transversely to the x-axis of the machine, to double the total number of jets emitting the spray tube, which results in an increase in the cleaning or conditioning performance of the spray tube, and in addition the jets at an angle to the z-axis, resulting in an increase in the cleaning or conditioning performance of the spray tube and a more thorough cleaning of double-layered sheet forming screens result. When arranging the Beams in the x-axis can be achieved an increase in the cleaning or conditioning performance of each nozzle. With the arrangement of the beam in the x-axis or transversely to the x-axis can be achieved with a significantly reduced water consumption by the use of smaller nozzle elements and correspondingly reduced beam diameter, for example, when doubling the number of beams adequate cleaning or conditioning performance of the nozzle wherein, as already mentioned, the volume flow of two jets with a diameter of 0.5 mm at the same water pressure corresponds to only about 60% of the volume flow of a jet of 1.0 mm diameter.
Die Düsenelemente der erfindungsgemäßen Düsenvorrichtung können vorteilhafterweise in unterschiedlichen Ausführungsformen einen zuströmseitigen Abschnitt des oder der Düsenkanäle bilden und dort entweder durch eine Durchtrittsöffnung des betreffenden Abschnitts des Düsenkörpers selbst gebildet sein oder als ein in dem jeweiligen Düsenkanal aufgenommenes, mit einer Durchtrittsöffnung versehenes Einsetzteil ausgebildet sein. Im ersten der beiden Fälle bildet demnach die den Düsenkörper zumindest teilweise durchgreifende Öffnung selbst das Düsenelement, während dieses im zweiten Fall durch ein in diesen Abschnitt eingesetztes, vorzugsweise in eine exakt passende Aufnahme des Düsenkörpers eingepresstes Einsetzteil gebildet ist. In beiden Fällen mündet das Düsenelement abströmseitig in den zugeordneten Düsenkanal, der auch ein gemeinsamer Kanal sein kann.In various embodiments, the nozzle elements of the nozzle device according to the invention can advantageously form an inflow-side section of the nozzle channel or channels and be formed there either through a passage opening of the relevant section of the nozzle body itself or as an insertion part accommodated in the respective nozzle channel and provided with a passage opening. Accordingly, in the first of the two cases, the opening which at least partially penetrates the nozzle body itself forms the nozzle element, whereas in the second case it is formed by an insert part inserted into this section and preferably pressed into a precisely fitting receptacle of the nozzle body. In both cases, the nozzle member opens downstream in the associated nozzle channel, which may also be a common channel.
Um einen optimal laminaren Strahl für einen geraume Zeit gewährleisten zu können ist das Einsetzteil einer Weiterbildung der Düsenvorrichtung vorteilhafterweise aus einem harten, verschleißarmen Material wie Rubin, Saphir, Diamant, einer Keramik, Hartmetall oder einem ähnlichen Hartmaterial vorgesehen.In order to ensure an optimally laminar jet for a long time the insert part of a development of the nozzle device is advantageously provided from a hard, low-wear material such as ruby, sapphire, diamond, a ceramic, hard metal or similar hard material.
Bei den von den Düsenelementen der erfindungsgemäßen Düsenvorrichtung erzeugten laminaren Flüssigkeitsstrahlen, insbesondere Wasserstrahlen, handelt es sich, im Sinne einer merklichen Reduktion des Volumenstroms an Flüssigkeit jeweils um Strahlen mit einem Durchmesser im Bereich von 0,1 mm bis 1,2 mm, bevorzugt im Bereich von 0,2 mm bis 0,9 mm, besonders bevorzugt im Bereich von 0,3 mm bis 0,6 mm.The laminar liquid jets, in particular jets of water, generated by the nozzle elements of the nozzle device according to the invention are in the sense of a marked reduction in the volume flow of liquid in each case to jets having a diameter in the range of 0.1 mm to 1.2 mm, preferably in the range from 0.2 mm to 0.9 mm, more preferably in the range of 0.3 mm to 0.6 mm.
Um den Düsenkörper einfach aus einer ersten Gebrauchsstellung in eine oder mehrere weitere Gebrauchsstellungen überführen zu können, ist bei einer Weiterbildung der Düsenvorrichtung dem Düsenkörper ein Werkzeug zugeordnet, welches ein Eingriffsmittel aufweist, mittels dessen der Düsenkörper um seine Längsachse verdreht werden kann.In order to be able to transfer the nozzle body simply from a first position of use to one or more other positions of use, in a further development of the nozzle device the nozzle body is assigned a tool which has an engagement means by means of which the nozzle body can be rotated about its longitudinal axis.
Bei einer anderen zweckmäßigen Weiterbildung der Düsenvorrichtung, die insbesondere von Vorteil bei mehreren Düsenkanälen ist, kann das Eingriffsmittel zum Verdrehen des Düsenkörpers in wenigstens eine hierfür vorgesehene, bevorzugt schlitzartige Öffnung des Düsenkörpers oder in wenigstens zwei Austrittsöffnungen der Düsenkanäle greifen. Für die schlitzartige Öffnung des Düsenkörpers, die zweckmäßigerweise bei zur Düsenkörperachse nicht parallelen Düsenkanälen einsetzbar ist, kann das Werkzeug mit einem Eingriffsmittel nach der Art der Klinge eines Schraubendrehers versehen sein, während bei achsparallelen, insbesondere im wesentlichen zylindrischen Düsenkanälen das Werkzeug mit komplementären Zylinderstücken als Eingriffsmittel versehen ist.In another expedient development of the nozzle device, which is particularly advantageous in the case of a plurality of nozzle channels, the engagement means can engage in at least one preferably slot-like opening of the nozzle body or in at least two outlet openings of the nozzle channels for rotating the nozzle body. For the slot-like opening of the nozzle body, which is expediently used with nozzle channels not parallel to the nozzle channels, the tool may be provided with an engagement means on the type of blade of a screwdriver, while in axially parallel, in particular substantially cylindrical nozzle channels, the tool with complementary cylinder pieces as engaging means is provided.
Zur einfachen Handhabung der Düsenvorrichtung bei Anordnung und Entfernung aus der Austrittsöffnung des betreffenden Spritzrohrs kann - je nach Ausführung der Aufnahmen an der Reinigungseinrichtung, beispielsweise also an einem Spritzrohr - bei einer anderen Weiterbildung der Vorrichtung der Düsenkörper einen Einsatz aus einem metallischen Material bilden, welcher in einem Träger aufgenommen ist.For easy handling of the nozzle device in the arrangement and removal from the outlet opening of the respective spray tube can - depending on the design of the recordings on the Cleaning device, for example, on a spray pipe - in another embodiment of the device of the nozzle body form an insert of a metallic material, which is accommodated in a carrier.
Um die Düsenvorrichtung an der betreffenden Reinigungsvorrichtung einfach und sicher montieren zu können, kann es bei einer Weiterbildung von Vorteil sein, an dem Träger einen zur Längsachse des Düsenkörpers koaxialen Eingriff vorzusehen, dessen Querschnitt die Strahlwege der laminaren Strahle der Düsenelemente über die Höhe des Trägers einfasst, so dass die Strahlen ungehindert aus dem Träger austreten können.In order to be able to mount the nozzle device on the relevant cleaning device in a simple and reliable manner, it may be advantageous in one embodiment to provide the support with a coaxial engagement with the longitudinal axis of the nozzle body whose cross-section encloses the beam paths of the laminar jets of the nozzle elements over the height of the support , so that the rays can exit freely from the carrier.
Gleichzeitig kann bei einer anderen Weiterbildung in dem Eingriff des Trägers vorteilhaft eine Nut eingebracht sein und weiter der Düsenvorrichtung ein Werkzeug, bspw. einen Innensechskantschlüssel, zugeordnet sein, das mit einem federbelasteten Haltemittel, etwa einer oder mehreren Kugeln, versehen ist, die in diese Nut eingreifen. Dadurch wird die Düsenvorrichtung gehalten und kann nicht von dem Werkzeug herunter fallen.At the same time, in another embodiment, a groove can advantageously be introduced in the engagement of the carrier and further the nozzle device can be assigned a tool, for example an Allen key, which is provided with a spring-loaded holding means, for example one or more balls, which engage in this groove intervention. Thereby, the nozzle device is held and can not fall off the tool.
Bevorzugt kann hierbei der Träger etwa als Plättchen ausgebildet sein oder einen im wesentlichen zylindersymmetrischen Körper mit wenigstens einer Handhabe zum Angriff eines Werkzeugs aufweisen, beispielsweise dadurch, dass ein Längsabschnitt mit geschlossener Außenkontur einen Polygonzug mit sechs Ecken bildet, so dass ein Werkzeug in Art eines Maulschlüssels einfach daran angreifen kann oder dieser Abschnitt einen sechseckigen Eingriff zum Einstecken eines Inbus aufweist.Preferably, in this case, the carrier may be formed as a small plate or have a substantially cylindrically symmetrical body with at least one handle for attacking a tool, for example, characterized in that a longitudinal section with closed outer contour forms a polygon with six corners, so that a tool in the manner of an open-end wrench can simply attack or this section has a hexagonal engagement for inserting an Allen.
Besonders einfach lässt sich eine Ausführung der Düsenvorrichtung in einer Austrittsöffnung einer als Spritzrohr ausgebildeten Reinigungseinrichtung durch Einschrauben festlegen, weswegen bei diese der Träger mit einem Festlegemittel in Art eines Gewindeabschnitts versehen sein kann, insbesondere kann der Träger hierbei mit einem Außengewinde zur Aufnahme in ein an der Austrittsöffnung befindliches, zugeordnetes Innengewinde versehen sein. Vorstellbar ist aber auch ein Träger mit einem Innengewinde zum Aufschrauben auf ein Außengewinde, der als Überwurfmutter ausgelegt ist.Particularly simple is an embodiment of the nozzle device in an outlet opening of a spray tube designed as Determine cleaning device by screwing, which is why in this the carrier may be provided with a fixing means in the manner of a threaded portion, in particular the carrier can be provided with an external thread for receiving in an outlet opening befindliches, associated internal thread. But it is also conceivable a carrier with an internal thread for screwing on an external thread, which is designed as a union nut.
Um den Düsenkörper als Einsatz während der Verwendung sicher in seiner Gebrauchsstellung zu halten und um einer Leckage vorzubeugen, kann der Einsatz in dem Träger mit einem Sicherungsmittel fixierbar und durch ein Dichtmittel abdichtbar sein. Das Dichtmittel kann hierbei etwa eine ringförmige Dichtung und das Sicherungsmittel ein vorgespannter Sicherungsring sein.In order to keep the nozzle body as an insert during use safely in its position of use and to prevent leakage, the insert in the carrier with a securing means can be fixed and sealed by a sealant. The sealing means may be an annular seal and the securing means may be a prestressed locking ring.
Eine weitere vorteilhafte Ausbildung der Düsenvorrichtung kann an ihrer Zuströmseite einschließlich der Zuströmöffnungen der Düsenelemente durch ein Reinigungswerkzeug beaufschlagbar sein, so dass unbeabsichtigte Verunreinigungen der Düsenöffnungen, die durch Fremdstoffanteile im verwendeten Spritzmedium hervorgerufen sind, durch das betreffende, innerhalb des Spritzrohres angeordnete Reinigungswerkzeug, beispielsweise eine rotierende Bürste, einfach und sicher entfernt werden können. Hierfür kann an der Düsenvorrichtung vorteilhafterweise auf einen vor dem Düsenelement angeordneten Anströmkanal verzichtet werden.A further advantageous embodiment of the nozzle device can be acted upon by a cleaning tool on its inlet side, including the inflow openings of the nozzle elements, so that unintentional contamination of the nozzle openings, which are caused by foreign matter in the spray medium used, by the relevant, arranged within the spray tube cleaning tool, such as a rotating Brush, easy and safe to remove. For this purpose, it is advantageously possible to dispense with a flow channel arranged upstream of the nozzle element on the nozzle device.
