Definitions
- the invention relates to a device for conditioning the surface of a belt of a belt processing plant by means of a fluid jet comprising a nozzle tube rotatable about a longitudinal axis, a plurality of nozzles for spraying the surface of the belt with the fluid and control means for temporarily supplying each nozzle with the fluid.
- a fluid jet comprising a nozzle tube rotatable about a longitudinal axis, a plurality of nozzles for spraying the surface of the belt with the fluid and control means for temporarily supplying each nozzle with the fluid.
- Fluida come in particular gases, liquids and liquid-solid mixtures into consideration.
- the invention relates to a strip processing system with at least one such device.
- Devices of the type mentioned are required in order to remove liquids or residues from belts conveyed in belt processing systems, in particular from high-speed metallic rolling belts, in particular oil, dirt, metal dust, scale, cooling lubricants or the like.
- the effective removal is necessary because for the further processing of the tapes usually only very low amounts of residue on the surface of the tape are allowed.
- the removal of the liquid of a cooling lubricant is insufficient, the remainder of the cooling lubricant forms a lubricating film after the tape has been coiled to form a band collar between its individual turns.
- This lubricating film can in particular during coiling of high-speed metallic rolling bands cause the individual coils of the covenant telescoping, so move during coiling in Haspelachsraum.
- the cooling lubricant removal is usually carried out with gaseous fluids, while the removal of the remaining residues is preferably carried out by means of liquid fluids.
- the device comprises a nozzle tube (18) which can be rotated about its longitudinal axis by means of a drive and into which two helical nozzle slots (19a, b) are introduced. Forming an annular gap (21), the nozzle tube (18) surrounds a hollow-cylindrical liquid reservoir (23) with a control slot (9) pointing in the direction of the strip (3), which extends over the entire in FIG. 10 shown width of the band (3) extends.
- the hollow cylindrical liquid reservoir (23) is held on the front side, at the same time serving as a liquid feedthrough pin (25 a, b) arranged laterally next to the belt supports (26 a, b).
- the pins (25 a, b) also serve as a receptacle for the pivot bearing (27) of the stationary liquid storage (23) rotating nozzle tube (18).
- the drive is for example via a pulley (28) of a belt drive.
- the nozzle slots (19 a, b) are fed via the control slot (9). Due to the large extent of the control slot (9) results in a correspondingly large length of the annular gap (21) between the fluid reservoir (23) and the rotating nozzle tube (18). As a result, correspondingly large leakage losses are caused. Due to the large extent of the control slot, the pressure of the fluid in the liquid reservoir (23) acts on a large area on the inner jacket of the nozzle tube (18). This results in large forces acting on the nozzle tube (18) and thus on the bearing (27).
- the invention is therefore the object of the invention to provide a device and a device having tape processing system in which the leakage and the forces on the nozzle tube and thus its storage are reduced.
- each nozzle is supplied via an at least partially extending in the direction of the longitudinal axis of the nozzle tube, arranged in or on the nozzle tube channel with fluid at one end of an inlet opening for the fluid and at the other end of which at least one of the nozzles is arranged, wherein the temporary supply of each nozzle with the fluid controls at least one control slot extending in the circumferential direction over a partial circumference and in the longitudinal direction over a partial length of the nozzle tube.
- the temporary supply of each nozzle to the fluid can be via a control slot, which is significantly smaller in relation to a prior art control slot extending the full width of the nozzle tube Control slot surface has. Furthermore, the temporary supply of the fluid via the channel associated with each nozzle allows the arrangement of the control slot or the control slots on one or both end sides of the device. The areal smaller control slots reduce the leakage and at the same time by the fluid temporarily acting on the nozzle tube and thus the storage forces.
- the control slot connected to a line supplying the fluid is stationary, for example arranged in a bearing housing of the device.
- the control slot extends in the circumferential direction over a partial circumference of the nozzle tube, in which an impingement of the nozzles is to take place with fluid.
- the midpoint angle associated with the subset is typically in a range between 15-45 degrees.
- the inlet openings of the channels, which are significantly smaller in cross-section with respect to the control slot, for supplying the nozzles with fluid, can be temporarily brought into overlap with the control slot during the rotation of the nozzle tube.
- the extending in the direction of the longitudinal axis of the nozzle tube portion of the channel can be introduced as a so-called deep hole from the front side into the nozzle tube.
- Each radial section is in particular aligned obliquely in the direction of the end face of the nozzle tube and receives a flat jet nozzle insert or serves as a full jet nozzle.
- the inlet opening is located at a radial section facing the interior of the nozzle tube.
- the inlet openings of the channels are preferably arranged on a ring surrounding the nozzle tube on an end face in a uniform distance from one another.
- the inlet openings of the channels pass successively into the area of action of the stationary control slot. While the inlet openings overlap with the control slot are located, the nozzles are supplied with fluid.
- horizontally varying lengths of the channels can be generated relative to the longitudinal axis of the nozzle tube a quasi transverse to the longitudinal axis of the nozzle tube migratory fluid jet, wherein the application of the nozzles preferably takes place sequentially from the band center to the band edge out.
- a plurality of control slots are arranged in or on the rotatable nozzle tube over the circumference of the nozzle tube, wherein the inlet opening of at least one end nozzle having a channel opens in each control slot.
- each control slot is assigned several channels.
- Each control slot arranged in the nozzle tube can be brought into temporary coincidence during the rotation of the nozzle tube with a smaller opening in cross-section with respect to the control slot, of a line which supplies the fluid. If several channels with several nozzles are connected to a control slot, these nozzles are acted upon in groups as long as the control slot is in register with the stationary outlet opening. This differs from the solution according to claim 2, characterized in that the group of applied channels "wanders".
- a further embodiment of the invention with circumferential control slots is characterized in that the control slot and thus the nozzle are only then acted upon by the fluid pressure when the circumferential control slot is in register with the stationary outlet opening in a stationary hollow cylindrical memory for the fluid.
- the control slot extends in the circumferential direction only over a partial circumference of the nozzle tube, in particular a partial circumference to which a midpoint angle between 15-45 degrees is assigned.
- each control slot in order to minimize the leakage losses, extends longitudinally over a partial length of the nozzle tube which corresponds to the extent of the inlet openings of the channels or the stationary outlet opening of the fluid-supplying line in the longitudinal direction.
- the small extent of the control slot in the longitudinal direction of the nozzle tube also makes it possible that each control slot is arranged exclusively on one of the two end sides of the device, in particular at the ends of the nozzle tube.
- At least one blocking element is arranged on the outer circumference of the nozzle tube, which prevents fluid leakage from the nozzle exclusively at the beginning of the temporary supply of each nozzle with the fluid.
- compressive fluids in the channel leading to the nozzle are first compressed. Since the pressure is insufficient in the compression phase, the control slot must release the fluid flow earlier accordingly. So that only small leakage losses occur during the compression phase, the nozzles are closed during the compression phase by the blocking element on the outer circumference of the nozzle tube.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Bedüsen der Oberfläche eines Bandes einer Bandbearbeitungsanlage mittels eines Fluidstrahls umfassend ein um eine Längsachse drehbares Düsenrohr, mehrere Düsen zum Bedüsen der Oberfläche des Bandes mit dem Fluid sowie Steuerungsmittel zur zeitweiligen Versorgung jeder Düse mit dem Fluid. Als Fluida kommen insbesondere Gase, Flüssigkeiten sowie Flüssigkeits-Feststoff-Gemische in Betracht. Außerdem betrifft die Erfindung eine Bandbearbeitungsanlage mit mindestens einer derartigen Vorrichtung.The invention relates to a device for conditioning the surface of a belt of a belt processing plant by means of a fluid jet comprising a nozzle tube rotatable about a longitudinal axis, a plurality of nozzles for spraying the surface of the belt with the fluid and control means for temporarily supplying each nozzle with the fluid. As Fluida come in particular gases, liquids and liquid-solid mixtures into consideration. Moreover, the invention relates to a strip processing system with at least one such device.
Vorrichtungen der genannten Art sind erforderlich, um von in Bandbearbeitungsanlagen geförderten Bändern, insbesondere von schnell laufenden metallischen Walzbändern Flüssigkeiten bzw. Rückstände zu entfernen, wie insbesondere Öl, Schmutz, Metallstaub, Zunder, Kühlschmiermittel oder dergleichen. Die wirksame Entfernung ist erforderlich, da für die weitere Verarbeitung der Bänder üblicherweise lediglich sehr niedrige Rückstandsmengen auf der Oberfläche des Bandes zulässig sind. Erfolgt insbesondere die Entfernung der Flüssigkeit eines Kühlschmiermittels nicht in ausreichendem Maße, so bilden die Reste des Kühlschmiermittels nach dem Aufhaspeln des Bandes zu einem Bandbund zwischen dessen einzelnen Windungen einen Schmierfilm. Dieser Schmierfilm kann insbesondere beim Aufhaspeln von schnell laufenden metallischen Walzbändern dazu führen, dass die einzelnen Windungen des Bundes teleskopieren, sich also beim Aufhaspeln in Haspelachsrichtung verschieben. Die Kühlschmiermittelentfernung erfolgt üblicherweise mit gasförmigen Fluiden, während die Entfernung der übrigen Rückstände vorzugsweise mittels flüssiger Fluide erfolgt.Devices of the type mentioned are required in order to remove liquids or residues from belts conveyed in belt processing systems, in particular from high-speed metallic rolling belts, in particular oil, dirt, metal dust, scale, cooling lubricants or the like. The effective removal is necessary because for the further processing of the tapes usually only very low amounts of residue on the surface of the tape are allowed. In particular, if the removal of the liquid of a cooling lubricant is insufficient, the remainder of the cooling lubricant forms a lubricating film after the tape has been coiled to form a band collar between its individual turns. This lubricating film can in particular during coiling of high-speed metallic rolling bands cause the individual coils of the covenant telescoping, so move during coiling in Haspelachsrichtung. The cooling lubricant removal is usually carried out with gaseous fluids, while the removal of the remaining residues is preferably carried out by means of liquid fluids.
Aus der
Da bei der Beaufschlagung von Bändern zum Entfernen von Rückständen bzw. Flüssigkeiten zunehmend höhere Drücke für das Fluid zum Einsatz gelangen, besteht ein Bedürfnis, die mit steigendem Druck proportional ansteigenden Leckverluste und Kräfte auf das Düsenrohr (18) zu reduzieren.As increasingly higher pressures for the fluid are used in the application of belts for the removal of residues or liquids, there is a need that with increasing pressure proportionally increasing leakage losses and forces on the nozzle tube (18) to reduce.
Ausgehend von dem Stand der Technik liegt der Erfindung daher die Aufgabe zur Grunde, eine Vorrichtung und eine die Vorrichtung aufweisende Bandbearbeitungsanlage zu schaffen, bei der die Leckverluste und die Kräfte auf das Düsenrohr und damit dessen Lagerung reduziert sind.Based on the prior art, the invention is therefore the object of the invention to provide a device and a device having tape processing system in which the leakage and the forces on the nozzle tube and thus its storage are reduced.
Diese Aufgabe wird bei einer Vorrichtung der eingangs erwähnten Art dadurch gelöst, dass jede Düse über einen zumindest teilweise in Richtung der Längsachse des Düsenrohres verlaufenden, im oder am Düsenrohr angeordneten Kanal mit Fluid versorgt wird, an dessen einem Ende eine Eintrittsöffnung für das Fluid und an dessen anderem Ende mindestens eine der Düsen angeordnet ist, wobei die zeitweilige Versorgung jeder Düse mit dem Fluid mindestens ein Steuerschlitz steuert, der sich in Umfangsrichtung über einen Teilumfang und in Längsrichtung über eine Teillänge des Düsenrohres erstreckt.This object is achieved in a device of the type mentioned above in that each nozzle is supplied via an at least partially extending in the direction of the longitudinal axis of the nozzle tube, arranged in or on the nozzle tube channel with fluid at one end of an inlet opening for the fluid and at the other end of which at least one of the nozzles is arranged, wherein the temporary supply of each nozzle with the fluid controls at least one control slot extending in the circumferential direction over a partial circumference and in the longitudinal direction over a partial length of the nozzle tube.
Indem jeder Düse das Fluid gezielt über einen ihr zugeordneten Kanal zugeführt wird, kann die zeitweilige Versorgung jeder Düse mit dem Fluid über einen Steuerschlitz erfolgen, der im Verhältnis zu einem sich über die gesamte Breite des Düsenrohrs erstreckenden Steuerschlitz nach dem Stand der Technik eine deutlich geringere Steuerschlitzfläche aufweist. Des Weiteren ermöglicht die zeitweilige Zufuhr des Fluids über den jeder Düse zugeordneten Kanal die Anordnung des Steuerschlitzes bzw. der Steuerschlitze an einer oder beiden Stirnseiten der Vorrichtung. Die flächenmäßig kleineren Steuerschlitze vermindern die Leckverluste und zugleich die durch das Fluid zeitweilig auf das Düsenrohr und damit die Lagerung einwirkenden Kräfte.By selectively supplying the fluid to each nozzle via a channel associated with it, the temporary supply of each nozzle to the fluid can be via a control slot, which is significantly smaller in relation to a prior art control slot extending the full width of the nozzle tube Control slot surface has. Furthermore, the temporary supply of the fluid via the channel associated with each nozzle allows the arrangement of the control slot or the control slots on one or both end sides of the device. The areal smaller control slots reduce the leakage and at the same time by the fluid temporarily acting on the nozzle tube and thus the storage forces.
In einer bevorzugten Ausführungsform der erfindungsgemäßen Vorrichtung ist der mit einer das Fluid zuführenden Leitung verbundene Steuerschlitz ortsfest, beispielsweise in einem Lagergehäuse der Vorrichtung angeordnet. Der Steuerschlitz erstreckt sich in Umfangsrichtung über einen Teilumfang des Düsenrohrs, in dem eine Beaufschlagung der Düsen mit Fluid erfolgen soll. Der dem Teilumfang zugeordnete Mittelpunktswinkel liegt typischerweise in einem Bereich zwischen 15 - 45 Grad. Die im Querschnitt gegenüber dem Steuerschlitz deutlich kleineren Eintrittsöffnungen der Kanäle zur Versorgung der Düsen mit Fluid sind während der Drehung des Düsenrohrs zeitweilig mit dem Steuerschlitz in Überdeckung bringbar.In a preferred embodiment of the device according to the invention, the control slot connected to a line supplying the fluid is stationary, for example arranged in a bearing housing of the device. The control slot extends in the circumferential direction over a partial circumference of the nozzle tube, in which an impingement of the nozzles is to take place with fluid. The midpoint angle associated with the subset is typically in a range between 15-45 degrees. The inlet openings of the channels, which are significantly smaller in cross-section with respect to the control slot, for supplying the nozzles with fluid, can be temporarily brought into overlap with the control slot during the rotation of the nozzle tube.
Der in Richtung der Längsachse des Düsenrohrs verlaufende Abschnitt des Kanals kann als so genannte Tieflochbohrung von der Stirnseite aus in das Düsenrohr eingebracht werden. Im Endbereich des axialen Abschnitts befindet sich mindestens ein radialer Abschnitt, der in der Mantelfläche des Düsenrohrs mündet. Jeder radiale Abschnitt ist insbesondere schräg in Richtung der Stirnseite des Düsenrohres ausgerichtet und nimmt einen Flachstrahl-Düseneinsatz auf oder dient selbst als Vollstrahldüse. An dem der Düse gegenüberliegenden Ende des Kanals befindet sich die Eintrittsöffnung an einem zum Inneren des Düsenrohres weisenden radialen Abschnitt.The extending in the direction of the longitudinal axis of the nozzle tube portion of the channel can be introduced as a so-called deep hole from the front side into the nozzle tube. In the end region of the axial section there is at least one radial section which opens in the lateral surface of the nozzle tube. Each radial section is in particular aligned obliquely in the direction of the end face of the nozzle tube and receives a flat jet nozzle insert or serves as a full jet nozzle. At the end of the channel opposite the nozzle, the inlet opening is located at a radial section facing the interior of the nozzle tube.
Bei der vorstehend beschriebenen Ausführungsform der erfindungsgemäßen Vorrichtung sind die Eintrittsöffnungen der Kanäle vorzugsweise auf einer ringförmig das Düsenrohr an einer Stirnseite umgebenden Linie in gleichmäßigem Abstand zueinander angeordnet. Durch kontinuierliches Drehen des Düsenrohrs in einer Drehrichtung gelangen die Eintrittsöffnungen der Kanäle sukzessiv in den Wirkungsbereich des ortsfesten Steuerschlitzes. Während sich die Eintrittsöffnungen in Überdeckung mit dem Steuerschlitz befinden, werden die Düsen mit Fluid beaufschlagt. Durch unterschiedlich lange horizontale Abschnitte der Kanäle kann bezogen auf die Längsachse des Düsenrohrs ein quasi quer zur Längsachse des Düsenrohrs wandernder Fluidstrahl erzeugt werden, wobei die Beaufschlagung der Düsen vorzugsweise nacheinander von der Bandmitte zur Bandkante hin erfolgt.In the embodiment of the device according to the invention described above, the inlet openings of the channels are preferably arranged on a ring surrounding the nozzle tube on an end face in a uniform distance from one another. By continuously rotating the nozzle tube in one direction of rotation, the inlet openings of the channels pass successively into the area of action of the stationary control slot. While the inlet openings overlap with the control slot are located, the nozzles are supplied with fluid. By horizontally varying lengths of the channels can be generated relative to the longitudinal axis of the nozzle tube a quasi transverse to the longitudinal axis of the nozzle tube migratory fluid jet, wherein the application of the nozzles preferably takes place sequentially from the band center to the band edge out.
In einer alternativen Ausgestaltung der Erfindung sind über den Umfang des Düsenrohres mehrere Steuerschlitze in oder an dem drehbaren Düsenrohr angeordnet, wobei die Eintrittsöffnung mindestens eines endseitig eine Düse aufweisenden Kanals in jedem Steuerschlitz mündet. Vorzugsweise sind jedem Steuerschlitz jedoch mehrere Kanäle zugeordnet.In an alternative embodiment of the invention, a plurality of control slots are arranged in or on the rotatable nozzle tube over the circumference of the nozzle tube, wherein the inlet opening of at least one end nozzle having a channel opens in each control slot. Preferably, however, each control slot is assigned several channels.
Jeder im Düsenrohr angeordnete Steuerschlitz ist während der Drehung des Düsenrohrs mit einer im Querschnitt gegenüber dem Steuerschlitz kleineren Austrittsöffnung einer das Fluid zuführenden Leitung zeitweilig in Überdeckung bringbar. Sofern an einem Steuerschlitz mehrere Kanäle mit mehreren Düsen angeschlossen sind, werden diese Düsen gruppenweise beaufschlagt, solange der Steuerschlitz mit der ortsfesten Austrittsöffnung in Überdeckung steht. Hiervon unterscheidet sich die Lösung nach Anspruch 2 dadurch, dass die Gruppe der beaufschlagten Kanäle "wandert".Each control slot arranged in the nozzle tube can be brought into temporary coincidence during the rotation of the nozzle tube with a smaller opening in cross-section with respect to the control slot, of a line which supplies the fluid. If several channels with several nozzles are connected to a control slot, these nozzles are acted upon in groups as long as the control slot is in register with the stationary outlet opening. This differs from the solution according to
Eine weiteren Ausgestaltung der Erfindung mit umlaufenden Steuerschlitzen zeichnet sich dadurch aus, dass der Steuerschlitz und damit die Düse erst dann mit dem Fluiddruck beaufschlagt werden, wenn der umlaufende Steuerschlitz mit der ortsfesten Austrittsöffnung in einem ortsfesten hohlzylindrischen Speicher für das Fluid in Überdeckung steht. Der Steuerschlitz erstreckt sich in Umfangsrichtung nur über einen Teilumfang des Düsenrohrs, insbesondere einen Teilumfang dem ein Mittelpunktswinkel zwischen 15 - 45 Grad zugeordnet ist. Infolge dessen erfolgt die Fluidbeaufschlagung der Düsen nur über einen geringen Teil des Düsenrohrumfangs. In Folge dessen sind sowohl die Leckverluste als auch die auf das Düsenrohr wirkenden Druckkräfte gering.A further embodiment of the invention with circumferential control slots is characterized in that the control slot and thus the nozzle are only then acted upon by the fluid pressure when the circumferential control slot is in register with the stationary outlet opening in a stationary hollow cylindrical memory for the fluid. The control slot extends in the circumferential direction only over a partial circumference of the nozzle tube, in particular a partial circumference to which a midpoint angle between 15-45 degrees is assigned. As a result, the fluid admission of the nozzles takes place only over a small part the nozzle tube circumference. As a result, both the leakage and the pressure acting on the nozzle tube pressure forces are low.
Um die Leckverluste zu minimieren, erstreckt sich jeder Steuerschlitz unabhängig von der Ausführungsform der Erfindung in Längsrichtung über eine Teillänge des Düsenrohres, die der Erstreckung der Eintrittsöffnungen der Kanäle bzw. der ortsfesten Austrittsöffnung der Fluid zuführenden Leitung in Längsrichtung entspricht. In Folge dessen ergibt sich gegenüber dem bisherigen Stand der Technik eine deutlich geringere Steuerschlitzfläche. Die geringe Erstreckung des Steuerschlitzes in Längsrichtung des Düsenrohrs ermöglicht es darüber hinaus, dass jeder Steuerschlitz ausschließlich an einer der beiden Stirnseiten der Vorrichtung, insbesondere an den Enden des Düsenrohrs angeordnet ist.Regardless of the embodiment of the invention, in order to minimize the leakage losses, each control slot extends longitudinally over a partial length of the nozzle tube which corresponds to the extent of the inlet openings of the channels or the stationary outlet opening of the fluid-supplying line in the longitudinal direction. As a result, compared to the prior art results in a significantly lower control slot area. The small extent of the control slot in the longitudinal direction of the nozzle tube also makes it possible that each control slot is arranged exclusively on one of the two end sides of the device, in particular at the ends of the nozzle tube.
Um bei kompressiven Fluiden die Leckverluste weiter zu reduzieren, ist in einer vorteilhaften Ausgestaltung der Erfindung am äußeren Umfang des Düsenrohrs mindestens ein Sperrelement angeordnet, das ausschließlich zu Beginn der zeitweiligen Versorgung jeder Düse mit dem Fluid einen Fluidaustritt aus der Düse unterbindet. Zu Anfang der Freigabe des Fluids durch den Steuerschlitz werden kompressive Fluide in dem zu der Düse führenden Kanal zunächst verdichtet. Da in der Verdichtungsphase der Druck nicht hinreichend ist, muss der Steuerschlitz den Fluidstrom entsprechend früher freigeben. Damit während der Verdichtungsphase nur geringe Leckverluste entstehen, werden die Düsen während der Verdichtungsphase durch das Sperrelement am äußeren Umfang des Düsenrohres verschlossen.In order to further reduce the leakage losses in compressive fluids, in an advantageous embodiment of the invention at least one blocking element is arranged on the outer circumference of the nozzle tube, which prevents fluid leakage from the nozzle exclusively at the beginning of the temporary supply of each nozzle with the fluid. At the beginning of the release of the fluid through the control slot, compressive fluids in the channel leading to the nozzle are first compressed. Since the pressure is insufficient in the compression phase, the control slot must release the fluid flow earlier accordingly. So that only small leakage losses occur during the compression phase, the nozzles are closed during the compression phase by the blocking element on the outer circumference of the nozzle tube.
Vorzugsweise beträgt der Druck, der den Düsen zugeleiteten Fluide zwischen 5 - 200 bar.Preferably, the pressure of the fluids supplied to the nozzles is between 5 and 200 bar.
Die erfindungsgemäße Vorrichtung ist regelmäßig Bestandteil einer Bandbearbeitungsanlage.The device according to the invention is regularly part of a strip processing system.

Die zeitweilige Versorgung jeder Düse (3) mit dem Fluid steuert ein Steuerschlitz (7), der sich in Umfangsrichtung über einen Teilumfang (2e) und in Längsrichtung über eine Teillänge (2d) des Düsenrohres (2) erstreckt. Der Steuerschlitz (7) ist ortsfest in einem Lagergehäuse (9) der Vorrichtung (1) angeordnet. Der Steuerschlitz (7)) mündet in der Mantelfläche des Lagergehäuses (9), um das das Düsenrohr (2) drehbar ist. Das Lagergehäuse(9) ragt an den Stirnseiten des Düsenrohrs (2) in einen von dem Düsenrohrdeckel (2f) gebildeten Einzug (2h) hinein. Über eine Leitung (8) im Inneren des Lagergehäuses (9) wird das Fluid dem Steuerschlitz (7) zugeführt. Zwischen dem Lagergehäuse (9)und dem Einzug (2h) des Düsenrohrdeckels (2f) befindet sich ein Ringspalt (25), der in Verbindung mit Dichtringen einen abgedichteten Übergang des Fluids von dem ortsfesten Steuerschlitz (7) zu den drehenden Eintrittsöffnungen (6) der Kanäle (5) sicherstellt.The temporary supply of each fluid to the nozzle (3) controls a control slot (7) extending circumferentially over a partial circumference (2e) and longitudinally over a partial length (2d) of the nozzle tube (2). The control slot (7) is stationary in a bearing housing (9) of the device (1). The control slot (7)) opens into the lateral surface of the bearing housing (9) around which the nozzle tube (2) is rotatable. The bearing housing (9) protrudes at the end faces of the nozzle tube (2) into an indentation (2h) formed by the nozzle tube cover (2f). Via a line (8) inside the bearing housing (9), the fluid is supplied to the control slot (7). Between the bearing housing (9) and the intake (2h) of the nozzle tube cover (2f) there is an annular gap (25), which in conjunction with sealing rings a sealed transition of the fluid from the stationary control slot (7) to the rotating inlet openings (6) Ensures channels (5).
Der Steuerschlitz (7) erstreckt sich in Umfangsrichtung über den Teilumfang (2e) des Düsenrohrs (2), in dem eine Beaufschlagung der Düsen (3) mit Fluid erfolgen soll. Der dem Teilumfang (2e) zugeordnete Mittelpunktswinkel liegt typischerweise in einem Bereich zwischen 15 - 45 Grad.The control slot (7) extends in the circumferential direction over the partial circumference (2e) of the nozzle tube (2), in which an impingement of the nozzles (3) is to take place with fluid. The midpoint angle associated with subscale (2e) is typically in a range between 15-45 degrees.
Die im Querschnitt gegenüber dem Steuerschlitz (7) deutlich kleineren Eintrittsöffnungen (6) der Kanäle (5) zur Versorgung der Düsen (3) mit Fluid überlappen sich während der Drehung des Düsenrohrs (2) um seine Drehachse (10) zeitweilig mit dem Steuerschlitz (7). Der Längsschnitt in
Bei der vorstehend beschriebenen Ausführungsform nach
Zur Montage der Vorrichtung (1) wird von einer Seite der Düsenrohrdeckel (2f) auf die Antriebswelle (12) geschoben. Nachdem von der anderen Seite das Düsenrohr (2) und der zweite Düsenrohrdeckel (2f) aufgeschoben sind, werden die beiden Düsenrohrdeckel (2f) an den Stirnseiten (2b) mit dem zylindrischen Abschnitt (2g) des Düsenrohrs(2) verschraubt.To mount the device (1), the nozzle tube cover (2f) is pushed onto the drive shaft (12) from one side. After the nozzle tube (2) and the second nozzle tube cover (2f) are pushed from the other side, the two nozzle tube cover (2f) are screwed to the cylindrical portion (2g) of the nozzle tube (2) at the end faces (2b).
Das Düsenrohr (2) kann auch mit mehreren Düsenreihen (19) versehen werden. Diese können gleichgerichtet oder gegenläufig und zusätzlich in Umfangsrichtung versetzt sein. Über einen sich in Richtung der Längsachse (4) erstreckenden Kanal (5) können die auf einer Winkelposition befindlichen Düsen (3) einer Düsenreihe (19) als auch mehrerer Düsenreihen mit Fluid versorgt werden.The nozzle tube (2) can also be provided with a plurality of nozzle rows (19). These can be rectified or offset in opposite directions and additionally in the circumferential direction. By means of a channel (5) extending in the direction of the longitudinal axis (4), the nozzles (3) of a row of nozzles (19) and of a number of rows of nozzles located at an angular position can be supplied with fluid.
Die Vorrichtung nach
Inneren des Speichers (24) wird das Fluid zugeführt. Zwischen dem Speicher (24) und dem Düsenrohr (2) befindet sich ein Ringspalt (25), der einen weitgehend abgedichteten Übergang des Fluids von jeder Austrittsöffnung (23) zu jedem Steuerschlitz (7) sicherstellt. Jeder Steuerschlitz (7) und damit die ihm zugeordnete Düse (3) werden erst dann mit Druck beaufschlagt, wenn der Steuerschlitz (7) die Position der Austrittsöffnung (23) in dem Speicher (24) erreicht. Da der Bereich der Beaufschlagung nur einen geringen Teil des Düsenrohrumfangs ausmacht, sind sowohl die Leckverluste als auch die auf das Düsenrohr (2) wirkenden Druckkräfte gering.Inside the memory (24), the fluid is supplied. Between the reservoir (24) and the nozzle tube (2) there is an annular gap (25) which ensures a largely sealed transition of the fluid from each outlet opening (23) to each control slot (7). Each control slot (7) and thus its associated nozzle (3) are only then pressurized when the control slot (7) reaches the position of the outlet opening (23) in the memory (24). Since the area of the loading makes up only a small part of the nozzle tube circumference, both the leakage losses and the pressure forces acting on the nozzle tube (2) are low.
