Description

Gegenstand der Erfindung ist ein Düsenbalken in einer Vorrichtung zur Erzeugung von Flüssigkeitsstrahlen, mit denen eine Verflechtung der Fasern einer entlang des Düsenbalkens geführten Faserbahn bewirkt wird.The invention relates to a nozzle beam in a device for generating liquid jets, with which an entanglement of the fibers of a guided along the nozzle beam fiber web is effected.

Aus der europäischen Patentschrift EP 1 472 397 B1 ist bereits ein Düsenbalken an einer Vorrichtung zur Erzeugung von Flüssigkeitsstrahlen zur Strahlverflechtung der Fasern einer entlang des Balkens geführten Faserbahn bekannt, der aus einem sich über die Arbeitsbreite der Faserbahn erstreckenden Oberteil und einem daran befestigten Unterteil besteht. In dem Oberteil ist über seine Länge eine Druckkammer angeordnet, der die unter Druck stehende Flüssigkeit z. B. stirnseitig zugeführt wird. Parallel dazu ist eine durch eine Zwischenwandung abgetrennte Druckverteilkammer vorgesehen, die mit der Druckkammer über in der Zwischenwandung angeordnete Flüssigkeitsdurchflussbohrung verbunden ist. An dem Unterteil ist ein Düsenblech mit den Bohrungen für die Düsen flüssigkeitsdicht gelagert. In der Druckverteilkammer ist ein runder Prallkörper exzentrisch zur Achse der kreisrunden Druckverteilkammer in Richtung zu den Durchflussbohrungen gehalten, um eine Beruhigung der Flüssigkeitsströmung hin zu den Bohrungen in dem Düsenstreifen zu bewirken.From the European Patent EP 1 472 397 B1 There is already known a nozzle bar on a device for generating liquid jets for beam interlacing of the fibers of a fiber web guided along the beam, which consists of an upper part extending over the working width of the fiber web and a lower part attached thereto. In the upper part of a pressure chamber is arranged over its length, which contains the pressurized liquid z. B. is supplied frontally. In parallel, a separated by an intermediate wall pressure distribution chamber is provided, which is connected to the pressure chamber via arranged in the intermediate wall fluid flow bore. At the lower part of a nozzle plate is mounted liquid-tight with the holes for the nozzle. In the pressure distribution chamber, a round baffle is held eccentric to the axis of the circular pressure distribution chamber towards the flow holes to cause the liquid flow to settle down to the holes in the nozzle strip.

Es wurde nun beobachtet, dass es in der Druckverteilkammer vor allem dann immer wieder zur Ansiedlung von Bakterienkulturen kommt, wenn die Anlage mit bestimmten Fasern, z.B. mit Baumwollfasern betrieben wird, wobei sich die Bakterien dann insbesondere auf dem Prallstab ansiedeln. Bei Verarbeitung anderer Fasern, z.B. reinen Chemiefasern werden derartige Probleme dagegen kaum beobachtet. Diese Bakterienkulturen führen zu einer unerwünschten Kontamination des Wasserkreislaufes, die vor allem bei der Produktion von Hygieneartikeln nicht hingenommen werden kann, für die von den Kunden der Anlagenbetreiber hohe hygienische Standards gesetzt werden.It has now been observed that bacterial cultures usually colonize the pressure distribution chamber, especially when the plant is operated with certain fibers, for example with cotton fibers, the bacteria then settling on the baffle bar in particular. When processing other fibers, such as pure chemical fibers, however, such problems are hardly observed. These bacterial cultures lead to undesirable contamination of the water cycle, which can not be tolerated, especially in the production of hygiene articles, for which the plant operators' customers set high hygienic standards.

Deshalb ist es erforderlich, die Druckverteilkammer und den Prallkörper regelmäßig zu reinigen und ihn von den dort angesiedelten Mikroorganismen zu befreien.Therefore, it is necessary to regularly clean the pressure distribution chamber and the baffle body and to rid him of the microorganisms located there.

Eine derartige Reinigung wird jedoch dadurch erschwert, dass zur Reinigung das Einführen einer Reinigungslanze in die Druckverteilkammer notwendig ist, was allerdings erst erfolgen kann, wenn vorher der Prallkörper entfernt worden ist.However, such cleaning is made difficult by the fact that for cleaning the insertion of a cleaning lance in the pressure distribution chamber is necessary, but this can only be done if previously the baffle body has been removed.

Die Entfernung des Prallkörpers aus der Druckverteilkammer ist technisch außerordentlich aufwendig. Denn der Prallkörper ist in einer Bohrung in der Druckverteilkammer fest verschraubt und kann nur dann entfernt werden, wenn vorher das gesamte Unterteil des Düsenbalkens demontiert wird. Das aber hat stundenlange Unterbrechungen der Produktion von wasservernadelten Warenbahnen zur Folge.The removal of the baffle body from the pressure distribution chamber is technically extremely expensive. Because the baffle body is firmly screwed into a bore in the pressure distribution chamber and can only be removed if previously the entire lower part of the nozzle beam is dismantled. But this has hours of interruptions in the production of water-needled webs result.

Es stelle sich deshalb die Aufgabe, einen neuen Düsenbalken zu entwickeln, bei dem die Reinigung der Druckverteilkammer und des Prallkörpers leichter durchgeführt werden kann. Insbesondere kommt es darauf an, den Prallkörper aus der Druckverteilkammer entnehmen zu können, ohne zugleich den gesamten Unterteil des Düsenbalkens demontieren zu müssen. Dieses Ziel lässt sich dadurch erreichen, dass der Prallkörper nicht mehr in der Druckverteilkammer verschraubt, sondern in diese nur hineingesteckt wird, so dass er dann seitlich aus der Druckverteilkammer ohne weiteres herausgezogen werden kann. Die erforderliche exzentrische Position des Prallkörpers in der Druckverteilkammer lässt sich dabei dadurch erreichen, dass seine Position in der Druckverteilkammer mit Abstandhaltern eingestellt wird, die als durchbrochene metallische Ringe mit nach unten offenem Distanzring auf den Prallkörper aufgeschoben und in bestimmten Abständen angeordnet werden.It is therefore the task to develop a new nozzle beam, in which the cleaning of the pressure distribution chamber and the impact body can be performed easily. In particular, it is important to be able to remove the baffle body from the pressure distribution chamber, without having to disassemble the entire lower part of the nozzle beam at the same time. This goal can be achieved in that the impact body is no longer screwed into the pressure distribution chamber, but only inserted into it, so that it can then be pulled out of the pressure distribution chamber laterally easily. The required eccentric position of the baffle body in the pressure distribution chamber can be achieved in that its position is adjusted in the pressure distribution chamber with spacers, which are pushed as a broken metallic rings with downwardly open spacer ring on the baffle and arranged at certain intervals.

Gegenstand der Erfindung ist deshalb ein Düsenbalken an einer Vorrichtung zur Erzeugung von Flüssigkeitsstrahlen zur Strahlverflechtung der Fasern einer Faserbahn, der aus einem sich über die Arbeitsbreite der Faserbahn erstreckenden Oberteil und einem flüssigkeitsdicht daran befestigen Unterteil besteht, wobei

in der Druckverteilkammer zwischen den Flüssigkeitsdurchbruchbohrungen und dem Schlitz ein Prallkörper über die Länge des Schlitzes angeordnet ist, der
f)
über seine Länge und über seinen Querschnitt frei umströmbar in der Druckverteilkammer angeordnet ist,
und der Prallkörper nicht mit dem Düsenbalken verschraubt, sondern in ihn hineingesteckt und aus ihm herausgezogen werden kann, wobei er mit Abstandshaltern in einer zentrischen oder exzentrischen Position gehalten wird.The subject of the invention is therefore a nozzle bar on a device for producing liquid jets for beam interlacing of the fibers of a fiber web, which extends from one over the working width of the fiber web Upper part and a liquid-tight fastened thereto lower part consists, wherein
a)
in the upper part over its length a pressure chamber is arranged, which is supplied to the pressurized liquid, and

is arranged freely in the pressure distribution chamber over its length and over its cross section,
and the impact body not bolted to the nozzle beam, but can be inserted into it and pulled out of it, being held with spacers in a centric or eccentric position.

In der erfindungsgemäßen Vorrichtung ist der Düsenbalken mit einem Prallkörper versehen, der vorzugsweise in Richtung zu den Durchflussbohrungen exzentrisch in der Druckverteilkammer angeordnet ist. Es hat sich gezeigt, dass die Umströmung des Prallkörpers dadurch gleichmäßiger wird und weniger Verwirbelungen in der Druckverteilkammer entstehen. Die Flüssigkeitsströmung vom Ausströmbereich der Flüssigkeit an den Flüssigkeitsdurchflussbohrungen und um den Prallkörper herum, der durch die exzentrische Anordnung zu der Wandung der Druckverteilkammer hin einen größeren Freiraum für die sich anschließende Vergleichmäßigung der entstandenen Verwirbelungen offen lässt, ermöglicht ein sauberes Erscheinungsbild der sich in dem Düsenstreifen ausbildenden Wasserstrahlen.In the device according to the invention, the nozzle bar is provided with an impact body, which is preferably arranged eccentrically in the direction of the flow bores in the pressure distribution chamber. It has been shown that the flow around the impact body is thereby uniform and less turbulence in the pressure distribution arise. The liquid flow from the discharge area of the liquid at the liquid flow holes and around the baffle body, which leaves a larger space for the subsequent equalization of the resulting turbulence open by the eccentric arrangement to the wall of the pressure distribution chamber, allows a clean appearance of forming in the nozzle strip water jets.

Es ist vorteilhaft, wenn zusätzlich für eine Flüssigkeitsvergleichmäßigung bereits vor der Druckverteilkammer gesorgt wird. Dies ist möglich, indem die Flüssigkeitsströmung sich nicht nur im Druckverteilraum, sondern auch in dem sich erweiternden Abströmbereich vergleichmäßigt, in welchem die Durchflussbohrungen in der Zwischenwandung in der Flüssigkeitsabflussrichtung im Durchmesser zuerst eng und dann größer ausgebildet sind.It is advantageous if, in addition, a homogenization of the liquid is already provided before the pressure distribution chamber. This is possible by making the liquid flow uniform not only in the pressure distribution space but also in the expanding discharge area in which the flow holes in the intermediate wall in the liquid discharge direction are first narrow and then larger in diameter.

Eine Vorrichtung der erfindungsgemäßen Art ist in den Zeichnungen beispielhaft dargestellt. Es zeigen:

A device of the type according to the invention is shown by way of example in the drawings. Show it:

Fig. 1 zeigt den erfindungsgemäßen Düsenbalken. Das Gehäuse des Düsenbalkens besteht aus einem Oberteil 1, das mit dem Unterteil 2 vielfach über die Länge von unten verschraubt ist. Das Oberteil 1 weist zwei Bohrungen 3 und 4 auf, von denen die obere die Druckkammer 3 und die untere die Druckverteilkammer 4 ist. Beide Kammern sind an der einen Stirnseite offen und an der anderen Seite flüssigkeitsdicht verschraubt. Durch die dort vorhandene Öffnung kann in die Druckkammer 3 die unter Druck gesetzte Flüssigkeit eingeführt werden. Die beiden Kammern 3 und 4 sind durch eine Zwischenwandung 5 voneinander getrennt. Über die Länge des Düsenbalkens verbinden eine große Anzahl von Durchflussbohrungen 6 in der Zwischenwandung 5 die beiden Kammern, so dass die in die Druckkammer 3 einströmende Flüssigkeit gleichmäßig verteilt über die Länge in die Druckverteilkammer 4 ausströmt. Die Druckverteilkammer ist nach unten offen durch einen schmalen Schlitz, der sich ebenfalls über die Länge des Balkens erstreckt.Fig. 1 shows the nozzle bar according to the invention. The housing of the nozzle beam consists of an upper part 1, which is often bolted to the lower part 2 over the length from below. The upper part 1 has two bores 3 and 4, of which the upper is the pressure chamber 3 and the lower the pressure distribution chamber 4. Both chambers are open at one end face and screwed liquid-tight on the other side. Through the existing there opening can be introduced into the pressure chamber 3, the pressurized liquid. The two chambers 3 and 4 are separated by an intermediate wall 5. Over the length of the nozzle bar connect a large number of flow holes 6 in the intermediate wall 5, the two chambers, so that the liquid flowing into the pressure chamber 3 flows evenly distributed over the length in the pressure distribution chamber 4. The Pressure distribution chamber is open at the bottom by a narrow slot, which also extends over the length of the beam.

Das Oberteil 1 ist mit dem Unterteil 2 fest und flüssigkeitsdicht schraubt. Die Dichtigkeit wird durch den O-Ring 9 bewirkt, der in einer Ringnut des Oberteils 1 einliegt. In der Mitte zwischen dem O-Ring 9 umschließt den Schlitz 8 ein Federvorsprung 15, der in einer entsprechenden Nut des Unterteils eingepasst ist und mit seinen Außenkanten das Düsenblech durch Kontakt mit dem Düsenstreifen 12 hält. In dem Boden der Nut des Unterteils 2 ist wiederum eine Ringnut eingebracht, in der der O-Ring 10 zur Abdichtung des Düsenstreifens 124 einliegt. In einer Linie unterhalb der Flüssigkeitsdurchflussbohrungen 6 und des Schlitzes 8 ist im Unterteil ebenfalls ein Schlitz 11 angebracht, der in seinem oberen Bereich nur sehr schmal ist und nur wenig mehr als die Breite der wirksamen Düsenöffnungen des Düsenstreifens 12 offen lässt.The upper part 1 is firmly screwed to the lower part 2 and liquid-tight. The tightness is effected by the O-ring 9, which rests in an annular groove of the upper part 1. In the middle between the O-ring 9 surrounds the slot 8, a spring projection 15 which is fitted in a corresponding groove of the lower part and holds with its outer edges, the nozzle plate by contact with the nozzle strip 12. In the bottom of the groove of the lower part 2, in turn, an annular groove is introduced, in which the O-ring 10 rests for sealing the nozzle strip 124. In a line below the liquid flow holes 6 and the slot 8, a slot 11 is also mounted in the lower part, which is only very narrow in its upper portion and only a little more than the width of the effective nozzle openings of the nozzle strip 12 leaves open.

Die Druckverteilkammer 4 wird erfindungsgemäß durch eine Bohrung in das Düsenbalkengehäuse hergestellt. Zum Austritt der Flüssigkeit aus der Druckverteilkammer 4 hin zum Düsenstreifen 12 ist der Schlitz 8 angebracht, der damit kleiner als der Querschnitt der Druckverteilkammer 4 ist. Die durch die Durchflussbohrungen 6 eintretende Flüssigkeit soll sich in der Verteilkammer gleichmäßig verteilen. Dazu dient das Volumen der Druckverteilkammer 4 und ein Prallkörper 13, der über die Länge der Druckverteilkammer 4 zwischen den Bohrungen 6 und dem Schlitz 8 gehalten ist. Der Prallkörper 13 ist mit Abstand zur Zwischenwand 5 gehalten und allseitig von der Flüssigkeit umströmbar. Um dies zu ermöglichen, sind auf dem Prallkörper mehrfach über die Länge des Düsenbalkens Abstandshalter angebracht, die vorteilhaft mit dem Prallkörper verschweißt und nach unten offen sind. Auf diese Weise trifft die Flüssigkeit aus den Durchflussbohrungen zunächst auf den Prallkörper 13, verteilt sich in der Verteilkammer 4 und strömt dann mit gleichem Druck über die Länge des Balkens durch die feinen Bohrungen des Düsenstreifens 12.The pressure distribution chamber 4 is produced according to the invention by a bore in the nozzle bar housing. To exit the liquid from the pressure distribution chamber 4 towards the nozzle strip 12, the slot 8 is mounted, which is smaller than the cross section of the pressure distribution chamber 4. The entering through the flow holes 6 liquid should be evenly distributed in the distribution chamber. The volume of the pressure distribution chamber 4 and an impact body 13, which is held over the length of the pressure distribution chamber 4 between the bores 6 and the slot 8, serve this purpose. The impact body 13 is held at a distance from the intermediate wall 5 and can be flowed around by the liquid on all sides. To enable this, spacers are repeatedly mounted on the baffle body over the length of the nozzle beam, which are advantageously welded to the baffle and open at the bottom. In this way, the liquid from the flow holes first meets the baffle 13, distributed in the distribution chamber 4 and then flows with the same pressure over the length of the beam through the fine holes of the nozzle strip 12th

Wie Fig. 1 zeigt, ist der kreisrunde Prallkörper 13 nicht zentrisch, sondern in Richtung zu den Durchflussbohrungen 6 versetzt angeordnet. Diese exzentrische Anordnung bewirkt, dass im noch freien Druckverteilraum 4 eine ruhigere, verlustfreie, strömungsgünstigere Flüssigkeitsströmung hin zu dem Düsenstreifen 12 entsteht. Die Folge davon sind sauber geformte Wasserstrahlen, die dann auch höhere Energie auf die Warenbahn übertragen können.As shown in FIG. 1, the circular baffle 13 is not centric, but arranged offset in the direction of the flow holes 6. This eccentric Arrangement causes the still free pressure distribution space 4 a calmer, lossless, streamlined liquid flow to the nozzle strip 12 is formed. The result is clean water jets, which can then transfer more energy to the web.

Da in der erfindungsgemäßen Vorrichtung der Prallkörper 13 nicht mit dem Düsenbalken verschraubt, sondern in der Druckverteilkammer 4 lediglich durch Abstandshalter in seiner Position gehalten wird, kann er in seiner ganzen Länge aus der Druckverteilkammer herausgezogen werden. Diese Anordnung hat auch den weiteren großen Vorteil, dass der Prallkörper nicht durch eine sonst übliche Senkbohrung befestigt werden muss, die immer wieder zu Verwirbelungen des Wasserstrahlen und damit zu Störungen der laminaren Strömung führt. Über die gesamte Länge der Prallkörpers ist jetzt die Oberfläche gleichmäßig und homogen ohne Strömungsfallen. Die Sicherung des Prallstabes gegen Verdrehung wird allerdings nicht durch die Abstandshalter selbst, sondern z.B. durch eine Nut/Feder-Konstruktion an der Stirnseite des Prallstabes verwirklicht.Since in the device according to the invention the baffle 13 is not bolted to the nozzle beam, but is held in position only in the pressure distribution chamber 4 by spacers, it can be pulled out in its entire length from the pressure distribution chamber. This arrangement also has the further great advantage that the impact body does not have to be secured by a conventional counterbore, which repeatedly leads to turbulence of the water jets and thus to disruptions of the laminar flow. Over the entire length of the impact body, the surface is now even and homogeneous without flow traps. However, securing the baffle bar against twisting is not done by the spacers themselves, but e.g. realized by a tongue and groove construction on the front side of the baffle bar.

Erfindungsgemäß kann in die Druckverteilkammer eine Desinfektionslanze eingeführt werden, die mit einer Desinfektionslösung oder mit heißem Wasser die angesiedelten Mikroorganismen entfernt. Nach erfolgter Reinigung der Druckverteilkammer 4 und des Prallstabes 13 wird dieser wieder in die Druckverteilkammer hineingesteckt und diese mit einem Deckel verschlossen.According to the invention, a disinfecting lance can be introduced into the pressure distribution chamber, which removes the settled microorganisms with a disinfectant solution or with hot water. After cleaning the pressure distribution chamber 4 and the baffle bar 13, this is again inserted into the pressure distribution chamber and closed with a lid.

Der erfindungsgemäße Düsenbalken mit einem leicht herausnehmbaren Prallköper ermöglicht eine unkomplizierte Reinigung und Entfernung der in dem Druckverteilkörper angesiedelten Mikroorganismen, ohne dass eine vollständige Demontage des Unterteils des Druckbalkens erforderlich ist.The nozzle bar according to the invention with an easily removable baffle body allows uncomplicated cleaning and removal of the microorganisms located in the pressure distribution body, without the need for complete disassembly of the lower part of the pressure bar.

Fig. 2 zeigt die auf den Prallkörper aufgesetzten Abstandshalter. Durch die Abstandshalter ist der Prallkörper gegen Verdrehung gesichert und kann so eine Vergleichmäßigung des Flüssigkeitsstromes sicherstellen.Fig. 2 shows the patch on the baffle body spacers. By the spacers of the baffle body is secured against rotation and can thus ensure a homogenization of the liquid flow.
