Description

Die Erfindung betrifft eine Vorrichtung zum Entwässern von strangförmigem Material, insbesondere von Kabeln.The invention relates to a device for dewatering strand-like Material, especially cables.

Beim Herstellen von Kabeln werden Drähte mit einer Kunststoffschicht ummantelt. Dies erfolgt beispielsweise durch einen Extruder, wobei das Kabel nach der Beschichtung eine Temperatur von beispielsweise 180 bis 240 °C aufweist. Da Kabel in einem kontinuierlichen Prozess hergestellt werden, bei dem die Transportgeschwindigkeit des Kabels bis zu 2000 m pro Minute betragen kann, muss das Kabel nach dem Beschichten gekühlt werden. Dies erfolgt indem das Kabel durch ein Wasserbad gezogen oder mit Wasser besprüht wird.When manufacturing cables, wires are made with a plastic layer jacketed. This is done for example by an extruder, the cable after coating, a temperature of, for example, 180 to 240 ° C. having. Because cables are manufactured in a continuous process in which the transport speed of the cable is up to 2000 m per minute the cable must be cooled after coating. This is done by the cable is pulled through a water bath or sprayed with water.

Auch bei der kontinuierlichen Herstellung von Schläuchen durch Extrusion müssen die Schläuche nach dem Extrudieren durch Wasser gekühlt werden. Ebenso erfolgt beim Drahtziehen während und nach dem Ziehvorgang eine Kühlung durch Ziehwasser, d.h. durch ein Gemisch aus Wasser und Öl.Also in the continuous production of hoses by extrusion the tubing must be cooled by water after extrusion. Likewise there is a wire drawing during and after the drawing process Cooling by drawing water, i.e. through a mixture of water and oil.

Um strangförmiges Material nach dem Kühlen mit Wasser oder anderen Kühlflüssigkeiten weiterverarbeiten zu können, muss das strangförmige Material entwässert werden. Unter Entwässerung wird das Entfernen der Kühlflüssigkeit verstanden, unabhängig davon, ob es sich um Wasser oder eine andere Kühlflüssigkeit handelt. Bei der Weiterverarbeitung handelt es sich beispielsweise um das Bedrucken der Kabel. Ein Bedrucken bzw. Beschriften der Kabel ist nur möglich, wenn das Kabel ausreichend trocken ist. To strand material after cooling with water or other The strand-like material must be able to process coolants further be drained. Removing the coolant is done under drainage understood whether it is water or another Coolant is acting. Further processing is, for example for printing on the cables. Printing or labeling the cables is only possible if the cable is sufficiently dry.

Zum Trocknen von strangförmigem Material ist es bekannt, das strangförmige Material durch einen Entwässerungstrog hindurch zu ziehen. Der Entwässerungstrog weist in Längsrichtung mehrere Öffnungen auf, die mit einer Saugvorrichtung verbunden sind. Mit Hilfe der Saugvorrichtung wird das Wasser von dem strangförmigen Material abgesaugt.For drying strand-like material, it is known to be strand-like Pull material through a drainage trough. The Drainage trough has several openings in the longitudinal direction, which with a Suction device are connected. With the help of the suction device, the water aspirated from the strand-like material.

Insbesondere bei hohen Transportgeschwindigkeiten kann mit bekannten Vorrichtungen zum Entwässern des strangförmigen Materials kein ausreichender Grad an Trockenheit erzielt werden, um das Material nach dem Entwässern beispielsweise zu bedrucken. Dies hat zur Folge, dass die Transportgeschwindigkeit des strangförmigen Materials in einer Anlage durch die Entwässerungsvorrichtung begrenzt ist.Particularly at high transport speeds, known ones can be used Devices for dewatering the strand material are not sufficient Degree of dryness can be achieved to the material after dewatering for example to print. As a result, the Transport speed of the strand-like material in a plant through the Drainage device is limited.

Aufgabe der Erfindung ist es, eine Vorrichtung zum Entwässern von strangförmigen Material zu schaffen, mit der ein höherer Grad an Trockenheit bzw. eine höhere Transportgeschwindigkeit des strangförmigen Materials erreicht werden kann.The object of the invention is to provide a device for dewatering to create strand-like material with a higher degree of dryness or a higher transport speed of the strand-like material is reached can be.

Die Lösung der Aufgabe erfolgt erfindungsgemäß durch die Merkmale des Anspruchs 1According to the invention, the object is achieved by the features of the claim 1

Die erfindungsgemäße Vorrichtung zum Entwässern von strangförmigem Material weist zusätzlich zu einem mit einer Saugvorrichtung verbundenen Entwässerungstrog, durch den das strangförmige Material hindurchgezogen wird, eine Düse auf. Die Düse ist derart angeordnet, dass ein Druckluftstrahl auf das strangförmige Material gerichtet ist, wobei die Düse vor oder an dem Entwässerungstrog angeordnet ist. Versuche haben gezeigt, dass durch das Vorsehen einer oder mehrerer Düsen, die einen Druckluftstrahl erzeugen, eine bessere Trocknung des strangförmigen Materials bzw. eine höhere Transportgeschwindigkeit des strangförmigen Materials bei gleichem Grad an Trockenheit erzielt werden kann.The device according to the invention for dewatering strand-like material points in addition to one connected to a suction device Drainage trough through which the strand-like material is drawn, a nozzle. The nozzle is arranged in such a way that a jet of compressed air hits the strand-shaped material is directed, the nozzle in front of or on the Drainage trough is arranged. Experiments have shown that through the Providing one or more nozzles that generate a jet of compressed air, one better drying of the strand-like material or a higher transport speed of the strand-like material with the same degree of dryness can be achieved.

Wie Versuche gezeigt haben, ist der Druck und die Abmessung des Druckluftstrahls vorzugsweise derart gewählt, dass durch das Auftreffen des Druckluftstrahls auf das strangförmige Material kein oder allenfalls ein geringes Abblasen des Wassers erfolgt. Vielmehr erfolgt ein besseres Lösen des Wassers von dem Material, so dass das Wasser einfacher und effektiver in dem Entwässerungstrog von der Saugvorrichtung abgesaugt werden kann. Durch den Druckluftstrahl findet eine Art Aufbrechen des das strangförmige Material umgebenden Wasserfilms durch einen Impuls statt. Versuche haben gezeigt, dass die Anordnung einer oder mehrerer derartiger Düsen gegenüber dem Entwässerungstrog oder in Transportrichtung des strangförmigen Materials vor dem Entwässerungstrog ein Absaugen größerer Wassermengen in dem Entwässerungstrog ermöglichen, so dass das strangförmige Material besser getrocknet ist.As experiments have shown, the pressure and dimensions of the Compressed air jet preferably chosen such that the impact of the Compressed air jet on the strand-shaped material little or no The water is blown off. Rather, the water dissolves better of the material so that the water is easier and more effective in the Drainage trough can be sucked off by the suction device. By the Compressed air jet finds a kind of breaking up of the strand-like material surrounding water film held by an impulse. Trials have shown that the arrangement of one or more such nozzles compared to the Drainage trough or in the direction of transport of the strand-shaped material the drainage trough a suction of larger amounts of water in the Allow drainage trough so that the strand-like material better is dried.

Besonders bevorzugt ist das Anordnen mindestens einer Düse im Eintrittsbereich des Entwässerungstrogs. Eine derartige Düse ist somit kurz vor oder am Anfang des Entwässerungstrogs, gesehen in Transportrichtung des strangförmigen Materials, angeordnet.Arranging at least one nozzle in the inlet area is particularly preferred of the drainage trough. Such a nozzle is therefore just before or at the beginning of the drainage trough, seen in the transport direction of the strand-shaped Materials, arranged.

Vorzugsweise ist der Düsenstrahl der mindestens einen Düse derart fein, dass er auf weniger als 50 %, insbesondere weniger als 30 % und besonders bevorzugt weniger als 10 % des Umfangs des strangförmigen Materials auftrifft. Vorzugsweise hat der Düsenstrahl hierbei einen Druck von mehr als 3 bar und insbesondere mehr als 5 bar. Sehr gute Entwässerungsergebnisse wurden beispielsweise mit der erfindungsgemäßen Vorrichtung erzielt bei einem Düsendurchmesser von 1,5 mm, zur Entwässerung eines strangförmigen Materials mit einem Außendurchmesser von 2,8 mm. Hierbei konnten die Ergebnisse noch verbessert werden durch erfindungsgemäßes Verwenden einer Flachstrahldüse, d.h. einer Düse mit mehreren in Reihe hintereinander angeordneten Bohrungen bzw. Düsenöffnungen. Insbesondere weist diese Düse mehr als 5 Öffnungen auf.The jet of the at least one nozzle is preferably so fine that it to less than 50%, especially less than 30% and particularly preferred strikes less than 10% of the circumference of the strand material. The nozzle jet preferably has a pressure of more than 3 bar and especially more than 5 bar. Very good drainage results were made achieved for example with the device according to the invention Nozzle diameter of 1.5 mm, for draining a strand-shaped Material with an outer diameter of 2.8 mm. Here, the Results can be improved even further by using a Flat jet nozzle, i.e. a nozzle with several in a row arranged bores or nozzle openings. In particular, this nozzle has more than 5 openings.

Bei einer besonders bevorzugten Ausführungsform ist gegenüber dem Entwässerungstrog zusätzlich zu der mindestens einen Düse eine Blasvorrichtung vorgesehen. Die Blasvorrichtung bläst den durch die Düse aufgebrochenen Wasserfilm von dem strangförmigen Material ab. Bei der Blasvorrichtung handelt es sich um eine Unterstützung der Saugvorrichtung. Bei einer der Saugvorrichtung gegenüberliegenden Blasvorrichtung wird im Wesentlichen am gesamten Umfang des strangförmigen Materials Wasser abgesaugt, bzw. abgeblasen. Insbesondere die Kombination einer Blasvorrichtung mit einer oder mehrerer Düsen, die im Eintrittsbereich des Entwässerungstrogs und/ oder gegenüber dem Entwässerungstrog angeordnet sind, hat sich als vorteilhaft erwiesen, da der durch die Druckluft aufgebrochene Wasserfilm sehr einfach von dem strangförmigem Material durch die Blasvorrichtung sowie durch die Saugvorrichtung entfernt werden kann.In a particularly preferred embodiment, the Drainage trough in addition to the at least one nozzle, a blowing device intended. The blower blows the one broken through the nozzle Water film from the strand material. The blower is acting it is a support of the suction device. With one of the suction devices opposite blowing device is essentially on the whole Extinguished or blown off the circumference of the strand-like material. In particular the combination of a blowing device with one or more Nozzles in the entry area of the drainage trough and / or opposite the Drainage trough has been found to be advantageous since the water film broken up by the compressed air very easily from that strand material through the blowing device and through the Suction device can be removed.

Vorzugsweise weisen die Düsen gegenüber der Blasvorrichtung einen geringeren Druckluftdurchsatz auf. Insbesondere beträgt der Druckluftdurchsatz der mindestens einen Düse gegenüber der Blasvorrichtung weniger als 1/2, besonders bevorzugt weniger als 1/5. Dies hat insbesondere den Vorteil, dass bei geringem Druckluftverbrauch eine gute Trocknung des strangförmigen Materials erzielt werden kann. Hierbei ist der Druck der Düsen vorzugsweise mindestens doppelt, besonders bevorzugt mindestens dreimal so hoch wie der Druck der Blasvorrichtung. Durch die mindestens eine Düse wird somit ein sehr feiner Druckluftstrahl bei hohem Druck aber wenig Druckluftverbrauch und durch die Blasvorrichtung ein höherer Druckluftverbrauch bei geringerem Druck realisiert. Insbesondere diese Kombination ist vorteilhaft, da die Erzeugung von hoher Druckluft, insbesondere in großen Mengen teuer ist. The nozzles are preferably smaller than the blowing device Compressed air flow rate. In particular, the compressed air throughput is at least one nozzle less than 1/2 compared to the blowing device, particularly preferably less than 1/5. This has the particular advantage that low compressed air consumption good drying of the strand-like material can be achieved. Here, the pressure of the nozzles is preferably at least twice, particularly preferably at least three times the pressure of the Blower. The at least one nozzle thus makes a very fine one Compressed air jet at high pressure but little compressed air consumption and through that Blower device realized a higher compressed air consumption at lower pressure. This combination in particular is advantageous since the generation of high Compressed air, especially in large quantities, is expensive.

Vorzugsweise weist die Saugvorrichtung und die Blasvorrichtung ein gemeinsames Gebläse auf. Dies hat den Vorteil, dass nur ein einziges Gebläse erforderlich ist, durch das gleichzeitig gesaugt und geblasen wird. Dies hat erhebliche Kosteneinsparungen zur Folge, da das zweite Gebläse entfällt.The suction device and the blowing device preferably have common blower on. This has the advantage that only one blower is required, through which is sucked and blown at the same time. this has considerable cost savings as the second blower is not required.

Um zu vermeiden, dass Wasser in das Gebläse gelangt, weist die Saugvorrichtung vorzugsweise einen dem Gebläse vorgeschalteten Wasserabscheider auf.To prevent water from getting into the fan, the Suction device preferably one upstream of the blower Water separator.

Bei einer besonders bevorzugten Ausführungsform der Erfindung ist dem Entwässerungstrog eine Abschleudervorrichtung vorgeschaltet. Insbesondere ist die Abschleudervorrichtung der den feinen Düsenstrahl erzeugenden Düse vorgeschaltet. Durch die Abschleudervorrichtung wird in einer Art Vorentwässerung Wasser von dem strangförmigen Material abgeschleudert. Dies geschieht dadurch, dass, vorzugsweise durch Vorsehen einer Umlenkeinrichtung als Bestandteil der Abschleudervorrichtung, das strangförmige Material umgelenkt wird. Durch dieses Umlenken des strangförmigen Materials aus der Transportrichtung wirken Zentrifugalkräfte. Diese bewirken ein Abschleudern von Wasser, Öl oder anderen auf der Oberfläche des strangförmigen Materials vorhandenen Flüssigkeiten u.dgl. Das Vorschalten einer Abschleudervorrichtung vor die Düse oder den Entwässerungstrog hat den Vorteil, dass das strangförmige Material vor dem Erreichen der Düse bzw. des Entwässerungstroges bereits vorgetrocknet ist. Somit sind leicht entfernbare Fluide bereits von dem strangförmigen Material entfernt.In a particularly preferred embodiment of the invention Drainage trough upstream of a centrifugal device. In particular is the spinner of the nozzle producing the fine jet upstream. By the spinner is in a kind Pre-drainage water thrown off the strand material. This happens in that, preferably by providing a deflection device as part of the centrifugal device, the strand-like material is redirected. By deflecting the strand-like material from the Centrifugal forces act in the direction of transport. These cause a spin off of Water, oil or other on the surface of the strand material existing liquids and the like The upstream of a spinner in front of the nozzle or the drainage trough has the advantage that the strand-like material before reaching the nozzle or Drainage troughs are already pre-dried. Thus are easily removable Fluids already removed from the strand material.

Vorzugsweise sind mehrere, insbesondere mindestens drei, Umlenkeinrichtungen vorgesehen. Durch die Umlenkeinrichtungen kann das strangförmige Material in einer horizontalen oder einer vertikalen Ebene oder einer beliebigen Zwischenebene ausgelenkt werden. Vorzugsweise erfolgt eine Auslenkung in einer vertikalen Ebene, um eine möglichst geringe Bautiefe der Vorrichtung zu ermöglichen. Vorzugsweise erfolgt durch mindestens eine der vorzugsweise mehreren Umlenkeinrichtungen ein Umlenken des strangförmigen Materials um mindestens 40°, besonders bevorzugt um mindestens 60° und insbesondere um mindestens 80°.Preferably, several, in particular at least three, deflection devices intended. The strand-like material can be deflected by the deflection devices a horizontal or vertical plane, or any Intermediate level can be deflected. A deflection preferably takes place in a vertical plane in order to minimize the overall depth of the device enable. Preferably, at least one of the preferably a plurality of deflection devices to deflect the strand-like material at least 40 °, particularly preferably by at least 60 ° and in particular by at least 80 °.

Besonders bevorzugt ist es, als Umlenkeinrichtungen keine starren Vorrichtungen vorzusehen, sondern Umlenkrollen anzuordnen. Die Umlenkrollen haben vorzugsweise eine Führungsnut, in der das strangförmige Material geführt ist. Die Führungsnut ist vorzugsweise V-förmig.It is particularly preferred that no rigid devices are used as deflection devices to provide, but to arrange pulleys. The pulleys have preferably a guide groove in which the strand-like material is guided. The Guide groove is preferably V-shaped.

Durch Versuche konnte überraschenderweise festgestellt werden, dass bei einem Öffnungswinkel oder V-Nut von mindestens 70° und besonders bevorzugt mindestens 80° eine Erhöhung der abgeschleuderten Flüssigkeitsmenge realisiert werden kann. Bei gleicher Transportgeschwindigkeit des strangförmigen Materials wird somit bei einem Winkel von vorzugsweise mindestens 80° eine größere Menge an Flüssigkeit von dem strangförmigen Material entfernt, d.h. abgeschleudert, als bei einer V-Nut mit geringerem Winkel. Versuche haben ferner gezeigt, dass der Winkel vorzugsweise kleiner als 90°, insbesondere im Bereich von 80° - 90° sein sollte.Experiments have surprisingly shown that one Opening angle or V-groove of at least 70 ° and particularly preferred realized at least 80 ° an increase in the amount of liquid thrown off can be. At the same transport speed of the strand-like material thus becomes larger at an angle of preferably at least 80 ° Amount of liquid removed from the strand material, i.e. thrown off than with a V-groove with a smaller angle. Have attempts further shown that the angle is preferably less than 90 °, in particular in Range should be 80 ° - 90 °.

Die Transportgeschwindigkeit des strangförmigen Materials beträgt vorzugsweise mindestens 400 m/min. Die Ergebnisse können durch ein Erhöhen der Transportgeschwindigkeit weiter verbessert werden.The transport speed of the strand-like material is preferably at least 400 m / min. The results can be increased by increasing the Transport speed can be further improved.

Bei der Abschleudervorrichtung handelt es sich um eine selbstständige Erfindung. Besonders bevorzugt ist jedoch das Verwenden der erfindungsgemäßen Abschleudervorrichtung in Verbindung mit der erfindungsgemäßen Entwässerungsvorrichtung.The centrifugal device is an independent invention. However, the use of the invention is particularly preferred Spin-off device in connection with the invention Dehydrator.

Nachfolgend wird die Erfindung anhand einer bevorzugten Ausführungsform unter Bezugnahme auf die anliegenden Zeichnungen näher erläutert. The invention is described below on the basis of a preferred embodiment with reference to the accompanying drawings.

Die dargestellte Ausführungsform zum Entwässern von strangförmigen Material 10 weist einen Entwässerungstrog 12 auf, durch den das strangförmige Material 10 in Längsrichtung hindurchgezogen wird. Im dargestellten Ausführungsbeispiel ist der Entwässerungstrog 12 rinnenförmig. Es kann sich auch um ein geschlossenes Rohr mit kreisringförmigem oder beliebigem anderen Querschnitt handeln. Der Entwässerungstrog 12 weist im Trogboden 14 Öffnungen 16 auf (Fig. 2), die mit einem Saugkanal 18 verbunden sind. In dem Saugkanal 18 wird mittels eines Gebläses 20 (Fig. 1) Unterdruck erzeugt. Hierzu ist der Saugkanal 18 über ein Rohr 22, einem Wasserabscheider 24 und ein zwischen dem Wasserabscheider 24 und dem Gebläse 20 vorgesehenen Rohr 26 mit dem Gebläse 20 verbunden.The illustrated embodiment for dewatering strand-like material 10 has a drainage trough 12 through which the strand-like material 10 is pulled in the longitudinal direction. In the illustrated embodiment the drainage trough 12 is channel-shaped. It can also be a closed one Pipe with an annular or any other cross-section act. The drainage trough 12 has openings 16 in the trough bottom (Fig. 2), which are connected to a suction channel 18. In the suction channel 18 generated by means of a blower 20 (Fig. 1) vacuum. This is the suction channel 18 via a pipe 22, a water separator 24 and a between the Water separator 24 and the blower 20 provided pipe 26 with the Blower 20 connected.

Durch den dem Gebläse 20 vorgeschalteten Wasserabscheider 24 ist verhindert, dass von dem Strangmaterial 10 abgesaugtes Wasser in das Gebläse 20 gelangt und dieses beschädigt. Der Wasserabscheider 24 weist ein mit einem Ventil 28 versehenes Ablassrohr 30 zum Ablassen des sich in dem Wasserabscheider 24 sammelnden Wassers auf. Zum automatischen Ablassen kann in dem Ablassrohr eine Pumpe vorgesehen sein, die durch einen in dem Wasserabscheider angeordneten Niveauregler gesteuert wird.The water separator 24 connected upstream of the blower 20 prevents that water drawn off from the strand material 10 gets into the blower 20 and damaged it. The water separator 24 has a valve 28 provided drain pipe 30 for draining the water separator 24 collecting water. Automatic drainage can be done in the drain pipe a pump can be provided by one in the water separator arranged level controller is controlled.

Das Gebläse 20 ist über ein Rohr 32 mit einem Luftaustrittsbalken 34 verbunden. Bei dem Luftaustrittsbalken 34 handelt es sich um ein in Längsrichtung des strangförmigen Materials 10 ausgerichteten Hohlkörper mit Luftaustrittsöffnungen. Die Luftaustrittsöffnungen sind auf das strangförmige Material 10 gerichtet. Aus dem Luftaustrittsbalken tritt somit ein auf das strangförmige Material gerichteter Luftstrom mit relativ geringem Druck aus, durch den das Entfernen des Wassers von dem strangförmigen Material 10 unterstützt wird. Der Luftaustrittsbalken kann mehrere Austrittsöffnungen aufweisen und/oder einen schlitzförmigen Luftaustrittsspalt.The blower 20 is connected to an air outlet beam 34 via a pipe 32. The air outlet bar 34 is a in the longitudinal direction of the strand-like material 10 aligned hollow body Air outlet openings. The air outlet openings are on the strand-shaped Material 10 directed. From the air outlet bar there is a step on the strand-shaped material directed air flow with relatively low pressure, by which the removal of water from the strand-like material 10 aids becomes. The air outlet bar can have a plurality of outlet openings and / or a slot-shaped air outlet gap.

Die Saugvorrichtung der Entwässerungsvorrichtung, die sich im wesentlichen aus dem Saugkanal 18 und dem Gebläse 20 zusammensetzt sowie die Blasvorrichtung, die sich im wesentlichen aus dem Luftaustrittsbalken 34 und dem Gebläse 20 zusammensetzt, weisen dasselbe Gebläse 20 auf. Durch das Gebläse 20 wird somit einerseits Luft aus dem Saugkanal 18 abgesaugt und andererseits Luft in den Luftaustrittsbalken 34 gefördert, um einen auf das strangförmige Material 10 gerichteten Luftstrom zu erzeugen.The suction device of the drainage device, which essentially consists of the suction channel 18 and the blower 20 and the Blower device, which essentially consists of the air outlet beam 34 and the blower 20, have the same blower 20. By the Fan 20 is thus sucked air from suction channel 18 on the one hand and on the other hand, air is conveyed into the air outlet bar 34 in order to get one onto the strand-shaped material 10 to produce directed air flow.

Erfindungsgemäß weist die Vorrichtung eine Düse 36 auf, die über ein Rohr 38 mit einer Drucklufterzeugungseinrichtung 40 wie einer Druckluftpumpe verbunden ist. Die Düse 36 ist im Eintrittsbereich 42 des Entwässerungstrogs 12 angeordnet. Der Eintrittsbereich 42 ist in einer Transportrichtung 44 des strangförmigen Materials 10 am Eintritt des Entwässerungstrogs vorgesehen. Handelt es sich bei dem strangförmigen Material beispielsweise um Kabel oder Ähnliches, weist die Düse 36 zu einer Vorderseite des Entwässerungstrogs 12 einen Abstand im Bereich von vorzugsweise weniger als 5 cm auf. Die Düse 36 ist somit in Transportrichtung 44 vor oder hinter einer Vorderkante des Entwässerungsdrucks innerhalb dieses Abstands angeordnet. According to the invention, the device has a nozzle 36, which is connected via a pipe 38 with a compressed air generating device 40 such as a compressed air pump connected is. The nozzle 36 is in the inlet area 42 of the drainage trough 12 arranged. The entry area 42 is in a transport direction 44 of the strand-like material 10 is provided at the entrance of the drainage trough. Is the strand-like material, for example, cables or Similarly, the nozzle 36 faces a front of the drain trough 12 a distance in the range of preferably less than 5 cm. The nozzle 36 is thus in the transport direction 44 in front of or behind a front edge of the Drainage pressure is arranged within this distance.

Die Düse 36 erzeugt einen feinen Düsenstrahl 46, der auf eine Oberfläche des strangförmigen Materials 10 trifft. Bezogen auf den Umfang des strangförmigen Materials 10 ist die Breite des Düsenstrahls 46 klein. Insbesondere ist diese kleiner als 30 % und besonders bevorzugt kleiner als 10 % des Umfangs.The nozzle 36 creates a fine jet 46 which is applied to a surface of the strand material 10 hits. Based on the circumference of the strand-shaped Material 10, the width of the nozzle jet 46 is small. In particular, this is less than 30% and particularly preferably less than 10% of the scope.

Dem gegenüber erzeugt der Luftbalken bzw. die Blasvorrichtung 34 einen beispielsweise kegelförmigen Luftstrahl 48, der sich mindestens über die gesamte Breite des strangförmigen Materials 10 erstreckt. Der zum Abblasen des durch den Strahl 46 aufgebrochenen Luftfilms dienende Strahl 48 weist einen erheblich geringeren Druck als der Strahl 46 auf.In contrast, the air bar or the blowing device 34 produces one for example conical air jet 48 which extends at least over the entire Width of the strand-like material 10 extends. The one to blow off the through jet 48 serving air jet broken open has a considerably lower pressure than the jet 46.

Bei einer alternativen Ausführungsform kann der Luftaustrittsbalken 34 entfallen. Bei dieser Ausführungsform ist es sodann möglich, die Düse 36 mit dem Gebläse 20 zu verbinden, so dass das Gebläse 20 sowohl mit dem Saugkanal 18 als auch mit der Düse 36 verbunden ist. Ferner ist es bei den beiden vorstehend beschriebenen Ausführungsformen, d.h. bei einer Ausführungsform mit oder ohne Luftaustrittsbalken 34, möglich, die Düse 36 mit einer gesonderten Druckluftquelle zu verbinden. Dies hat den Vorteil, dass hohe Drücke erzeugt werden können.In an alternative embodiment, the air outlet bar 34 can be omitted. In this embodiment, it is then possible to use the nozzle 36 with the blower 20 to connect, so that the fan 20 with both the suction channel 18 and is connected to the nozzle 36. It is also the case with the two above described embodiments, i.e. in one embodiment with or without air outlet bar 34, the nozzle 36 with a separate one Connect compressed air source. This has the advantage that it generates high pressures can be.

Der Entwässerungstrog 12 weist eine im Querschnitt halbkreisförmige Entwässerungsrinne 50 (Fig. 2) auf. Um mit der Entwässerungsvorrichtung unterschiedliche Strangmaterialien 10 entwässern zu können, ist der Entwässerungstrog 12 austauschbar, so dass unterschiedliche Entwässerungströge 12 mit unterschiedlichen Entwässerungsrinnen 50 vorgesehen werden können. Die Entwässerungsrinnen 50 können in Abhängigkeit des zu entwässernden Materials unterschiedliche Querschnitte sowie unterschiedliche Querschnittsabmessungen aufweisen. The drainage trough 12 has a semicircular cross section Drainage channel 50 (Fig. 2). To with the drainage device to be able to dewater different strand materials 10 is the Drainage trough 12 interchangeable, so that different Drainage troughs 12 with different drainage channels 50 can be provided. The drainage channels 50 may be dependent of the material to be dewatered different cross sections as well have different cross-sectional dimensions.

Ferner weist die erfindungsgemäße Entwässerungsvorrichtung eine Abschleudervorrichtung 52 (Fig. 1) auf. Diese ist im dargestellten Ausführungsbeispiel der Düse 36 in Transportrichtung 44 vorgeschaltet.Furthermore, the drainage device according to the invention has a Spin-off device 52 (FIG. 1). This is shown in the Embodiment of the nozzle 36 upstream in the transport direction 44.

Die Abschleudervorrichtung 52 weist im dargestellten Ausführungsbeispiel drei Umlenkeinrichtungen in Form von Umlenkrollen 54 auf. Die Umlenkrollen 54 sind im dargestellten Ausführungsbeispiel identisch. In Transportrichtung 44 des strangförmigen Materials 10 sind die Umlenkrollen 54 vertikal zueinander versetzt angeordnet, wobei die in Transportrichtung erste und letzte Umlenkrolle 54 in derselben Ebene angeordnet ist. Die Umlenkrollen 54 (Fig. 5) weisen eine am Umfang verlaufende Führungsnut 56 auf, die vorzugsweise V-förmig ist. Die V-förmige Führungsnut 56 weist hierbei einen Winkel α von vorzugsweise mindestens 70°, besonders bevorzugt mindestens 75° und insbesondere mindestens 80° auf. Untersuchungen haben ergeben, dass bei derartigen Winkeln α der Führungsnut 56 überraschenderweise ein besonders gutes Abschleudern der auf dem strangförmigen Material 10 haftenden Materialien erfolgt.The spinner 52 has three in the illustrated embodiment Deflection devices in the form of deflection rollers 54. The deflection rollers 54 are identical in the illustrated embodiment. In the transport direction 44 of the strand material 10, the deflection rollers 54 are vertical to each other staggered, the first and last pulley in the direction of transport 54 is arranged in the same plane. The deflection rollers 54 (FIG. 5) have one on the circumferential guide groove 56, which is preferably V-shaped. The V-shaped guide groove 56 has an angle α of preferably at least 70 °, particularly preferably at least 75 ° and in particular at least 80 °. Studies have shown that such Angles α of the guide groove 56 are surprisingly particularly good Throwing off the materials adhering to the strand-like material 10 he follows.

Im dargestellten Ausführungsbeispiel wird das strangförmige Material 10 durch die in Tränsportrichtung 44 erste Umlenkrolle 54 in Richtung der zweiten Umlenkrolle 54 nach unten umgelenkt. Hierbei erfolgt eine Umlenkung von ca. 90°. Zwischen der zweiten und dritten Umlenkrolle 54 erfolgt wiederum eine Umlenkung von etwa 90° und durch die letzte Umlenkrolle 54 sodann wieder eine Umlenkung in die Transportrichtung, d.h. um weitere 90°. In der zweiten Umlenkrolle 54 liegt das strangförmige Material 10 somit etwa an der Hälfte der Umlenkrolle 54 an und wird insgesamt um 180° umgelenkt. Durch die drei Umlenkvorgänge des strangförmigen Materials, die Krümmungen des Materials 10 in unterschiedliche Richtung hervorrufen, wird Flüssigkeit oder anderes an dem strangförmigen Material haftendes Material abgeschleudert. In the illustrated embodiment, the strand-like material 10 is through the first deflection roller 54 in the direction of the tear water 44 in the direction of the second Deflection roller 54 deflected downwards. Here there is a deflection of approx. 90 °. Between the second and third deflection pulley 54 there is again one Deflection of about 90 ° and then through the last pulley 54 again Redirection in the transport direction, i.e. by another 90 °. In the second Deflection roller 54, the strand-like material 10 is thus about half of the Deflection roller 54 and is deflected by a total of 180 °. Through the three Deflection of the strand-like material, the curvatures of the material 10 cause in different directions, liquid or something else material sticking to the strand-shaped material is thrown off.

Um beim Abschleudern von der ersten und der letzten Umlenkrolle 54 zu vermeiden, dass abgeschleudertes Material wieder auf das strangförmige Material zurücktropft o.dgl., ist eine Auffangeinrichtung 58 vorgesehen. Bei der Auffangeinrichtung 58 kann es sich um ein zwischen der ersten und der letzten Umlenkrolle 54 angeordnetes vertikales Blech handeln, das am unteren Ende ein Auffangrinne 60 aufweist.In order to be spun off from the first and the last deflecting roller 54 avoid throwing material back onto the strand-like material dripping back or the like, a collecting device 58 is provided. In the Catcher 58 may be one between the first and the last Deflection roller 54 arranged vertical sheet, the one at the lower end Has gutter 60.
