Abstract

1. A device for filling an electrical and/or optical cable, particularly but not exclusively a communications cable, with a filling material which renders the cable waterproof in the longitudinal direction, the filling device consisting of a filling chamber, two sealing pipes which serve respectively as inlet and outlet for the chamber, and a preceding vessel which is under vacuum, characterised in that the filling chamber (12) is preceded by a vacuum vessel (20) which serves for the degassing of both the cable core (8) to be filled and of the new filler material and the regenerated filler material recycled during the filling process.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Füllen eines elektrischen und/oder optischen Kabels, insbesondere eines Nachrichtenkabels, mit einer das Kabel längswasser= dichtenden Füllmasse, wobei die Füllvorrichtung aus einer Füllkammer und zwei als Ein- und Austritt für die Kammer dienenden Dichtrohren besteht.The invention relates to a device for filling an electrical and / or optical cable, in particular a communication cable, with a filling compound sealing the cable alongside water, the filling device consisting of a filling chamber and two sealing tubes serving as an inlet and outlet for the chamber.

Bekanntlich werden Kabelseelen mit einer wasserabweisenden Füllmasse gefüllt, um eventuell in die Kabelseele eingedrungenes Leckwasser daran zu hindern, sich längs der in der Kabelseele vorhandenen Kanäle (Zwickel) auszubreiten. Hierfür werden Füllvorrichtungen verwendet, die aus einer Füllkammer und Ein- und Austrittsdichtrohren bestehen (DE-PS 27 26 404). In diese Füllkammer wird die Füllmasse unter Druck in die Kabelseele gepreßt, damit sie auch in die relativ engen Zwischenräume im Innern der Kabelseele gelangt. Beim Füllen muß darauf geachtet werden, daß die Füllmasse gasfrei ist, weil sich eventuell in der Füllmasse eingeschlossenes Gas im Kabel separieren und dabei Kanäle bilden kann, längs denen sich später Leckwasser ausbreiten würde.As is known, cable cores are filled with a water-repellent filling compound in order to prevent any leakage water which has penetrated into the cable core from spreading along the channels (gusset) present in the cable core. For this purpose, filling devices are used which consist of a filling chamber and inlet and outlet sealing tubes (DE-PS 27 26 404). In this filling chamber, the filling compound is pressed into the cable core under pressure, so that it also reaches the relatively narrow spaces in the interior of the cable core. When filling, care must be taken to ensure that the filling compound is gas-free because any gas enclosed in the filling compound can separate in the cable and thereby form channels along which leakage water would later spread.

Das Problem der unerwünschten Lufteinschlüsse stellt sich insbesondere bei hochviskosen Füllmassen, bei denen die eigentliche wasserabweisende, wachsartige Füllmasse .(Petrolat) Zuschlagstoffe, z. B. in Form von elastischen Hohlkörpern,-enthält, die aufgrund ihrer geringen thermischen Stabilität ein Aufschmelzen der Füllmasse nicht erlauben oder bei Füllmassen, die durch Temperaturerhöhung keine ausreichende Viskositätserniedrigung erfahren.The problem of undesirable air pockets arises in particular in the case of highly viscous filling compounds, in which the actual water-repellent, wax-like filling compound . (Petrolat) aggregates, e.g. B. in the form of elastic hollow bodies, contains, which due to their low thermal stability do not allow the filling compound to melt or in the case of filling compounds caused by an increase in temperature do not experience a sufficient reduction in viscosity.

Kabelfüllmassen ohne Füllstoffe werden zunächst aufgeschmolzen. Dabei kann die in der Masse eingeschlossene Luft bzw. sonstige Gasanteile leicht aus der verflüssigten Masse entweichen. Anschließend wird die Füllmasse entweder im flüssigen Zustand, d. h. heiß, oder nach Abkühlung in die Kabelseele gepreßt. Die beim Füllprozeß anfallende Überschußmasse wird ebenfalls wieder durch Aufschmelzen entgast.Cable fillings without fillers are first melted. The air enclosed in the mass or other gas components can easily escape from the liquefied mass. The filling compound is then either in the liquid state, i.e. H. hot, or pressed into the cable core after cooling. The excess mass obtained during the filling process is also degassed again by melting.

Das Problem des gasfreien Füllens von Füllmassen mit Zuschlagstoffen ist ohne Einsatz eines erhöhten apparativen Aufwandes noch nicht zufriedenstellend gelöst,-insbesondere bereitet das Entgasen der dabei anfallenden Uberschußmasse in einem Online-Prozeß erhebliche Schwierigkeiten. Dabei wird nämlich durch die Überschußmasse ein erheblicher Anteil unerwünschter Luft in die Kabelseele eingeschleppt. Es wurden Werte für den Gasanteil bis zu 10 Volumenprozent gemessen.The problem of gas-free filling of fillings with additives has not yet been satisfactorily resolved without the use of an increased outlay on equipment, in particular the degassing of the excess mass obtained in this way presents considerable difficulties in an online process. This is because the excess mass entrains a considerable proportion of undesirable air into the cable core. Values for the gas fraction up to 10 percent by volume were measured.

Der Erfindung liegt die Aufgabe zugrunde, eine Füllvorrichtung anzugeben, bei der eine einwandfreie Entgasung sowohl der Kabelseele als auch der neuen und der wieder zu verwendenden Füllmasse ohne großen zusätzlichen apparativen Aufwand erreicht wird. Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlagen, daß der Füllkammer ein Vakuumbehälter vorgeschlatet ist, der sowohl für das Entgasen der zu füllenden Kabelseele als auch der neuen und der erneut in den Füllprozeß zurückgeführten Füllmasse ausgebildet ist.The invention has for its object to provide a filling device in which a perfect degassing of both the cable core and the new and the reusable filling compound is achieved without great additional equipment. To achieve this object of the invention is proposed according to that of the filling chamber, a vacuum container is eschlatet prior g which is formed to be filled cable core as well as the new and again fed back into the filling compound filling process for both the degassing.

Auf diese Weise wird nur eine einzige Evakuierungseinrichtung eingesetzt, die so angeordnet und ausgebildet ist, daß sie gleichzeitig drei Funktionen erfüllt:

  • 1. Entgasen der Kabelseele
  • 2. Entgasen der Frischmasse und
  • 3. Entgasen der wieder zu verwendenden Überschußmasse. Werden hochviskose kompressible Füllmassen verwendet, ist das Problem der Uberschußmasse besonders gravierend. Z. B. ist eine Füllmasse, die aus 40 Voluzmenprozent Petrolat und 60 Volumenprozent kleinster Hohlkörper mit elastischen Wandungen besteht, bei einem Fülldruck von etwa 15 bar um rd. 50 % komprimierbar. Selbst bei eng angepaßten Dichtrohren bleiben nur etwa 60 % der Füllmasse in der Kabelseele, während die restlichen 40 % herausquellen und abgestreift werden müssen.
In this way, only a single evacuation device is used, which is arranged and designed in such a way that it simultaneously fulfills three functions:
  • 1. Degassing the cable core
  • 2. Degassing the fresh mass and
  • 3. Degassing the excess mass to be reused. If highly viscous compressible filling materials are used, the problem of the excess material is particularly serious. For example, a filling compound consisting of 40 percent by volume petroleum jelly and 60 percent by volume of the smallest hollow body with elastic walls, at a filling pressure of around 15 bar by approx. 50% compressible. Even with tightly matched sealing tubes, only about 60% of the filling compound remains in the cable core, while the remaining 40% swell out and must be stripped off.

In Ausgestaltung der Erfindung wird man in dem Vakuumbehälter eine eine Druckdifferenz aufbauende Fördereinrichtung anordnen, um mit der Integration dieser Fördereinrichtung sicherzustellen, daß der Druckunterschied zwischen dem Vakuumbehälter und der Atmosphäre ohne Schwierigkeiten überwindbar ist. Dabei wirkt die zu fördernde Füllmasse selbst als Dichtungsmittel zwischen den Bereichen mit unterschiedlichem Druck.In an embodiment of the invention, a conveyor device that builds up a pressure difference will be arranged in the vacuum container in order to ensure with the integration of this conveyor device that the pressure difference between the vacuum container and the atmosphere can be overcome without difficulty. The filling compound to be conveyed itself acts as a sealant between the areas with different pressures.

Auf der Austrittsseite der Füllvorrichtung im Bereich der Öffnung des Austrittsdichtrohres und eines nachgeschalteten Kalibriernippels empfiehlt es sich, einen Auffangbehälter anzuordnen, um auf jeden Fall die an beiden Stellen austretende.Uberschußmasse auffangen zu können. Wie im Absatz zuvor erwähnt, ist dies besonders bei Verwendung hochviskoser kompressibler Füllmassen wichtig. Es empfiehlt sich ferner, auch in dem Auffangbehälter eine eine Druckdifferenz aufbauende Fördereinrichtung anzuordnen, um so die Rückförderung der Überschußmasse erheblich zu erleichtern.On the outlet side of the filling device in the area of the opening of the outlet sealing tube and a downstream calibration nipple, it is advisable to arrange a collecting container in order to be able to collect the excess mass that escapes at both points. As mentioned in the paragraph above, this is particularly important when using highly viscous compressible fillers. It is also recommended that a conveying device that builds up a pressure difference is also arranged in the collecting container in order to considerably facilitate the return of the excess mass.

Eine besonders vorteilhafte Ausführungsform erhält man, wenn man die erwähnten druckaufbauenden Fördereinrichtungen als Kammer- oder Doppelschneckenförderer ausbildet. Das Einleiten der Füllmasse in den Vakuumbehälter erfolgt vorzugsweise über einen Masseverteiler, der bevorzugt in Form einer Strainerplatte ausgebildet wird, weil damit eine besonders große Oberfläche der zu entgasenden Masse erreichbar ist.A particularly advantageous embodiment is obtained if the pressure-increasing conveying devices mentioned are designed as chamber or twin-screw conveyors. The filling compound is preferably introduced into the vacuum container via a mass distributor, which is preferably designed in the form of a strainer plate, because a particularly large surface area of the mass to be degassed can thus be reached.

Schließlich kann man die neue Vorrichtung vorteilhafterweise dadurch ergänzen, daß die Zulaufleitung der Frischmasse bzw. der Zulaufleitungen für die Komponenten einer mit Zuschlagsstoffen versehenen Füllmasse in dem. Auffangbehälter münden. Eine so ausgebildete Anlage eignet sich besonders gut für Füllmassen niedriger Dielektrizitätszahl, die im allgemeinen aus einer Mischung von kompressiblen Hohlkörpern und Petrolat bestehen.Finally, the new device can advantageously be supplemented in that the feed line of the fresh mass or the feed lines for the components of a filler provided with additives in the. Collection container open. A system designed in this way is particularly suitable for fillers with a low dielectric constant, which generally consist of a mixture of compressible hollow bodies and petrolatum.

Die Erfindung wird anhand eines in der Zeichnung dargestellten und nachfolgend näher beschriebenen Ausführungsbeispieles im einzelnen erläutert.The invention is explained in detail with reference to an embodiment shown in the drawing and described in more detail below.

In der einzigen Figur ist eine Füllvorrichtung gemäß der Erfindung in Form eines Blockschemas dargestellt.In the single figure, a filling device according to the invention is shown in the form of a block diagram.

Die Kabelseele 8, deren Transportrichtung durch den Pfeil 9 gekennzeichnet ist, wird in einer Füllvorrichtung 10 mit einer Dichtmasse gefüllt, die eine Ausbreitung von Leckwasser längs der Kabelseele verhindert. Die Füllvorrichtung besteht aus einem dem Eintritt der Kabelseele dienenden Dichtrohr 11, der eigentlichen Füllkammer 12 und einem Austrittsdichtrohr 13. Das Eintrittsdichtrohr ist vakuumdicht mit einem Vakuumbehälter 20 verbunden. Beide Dichtrohre sind dem Seelendurchmesser angepaßt und drehbar ausgebildet, wie es in der älteren Patentanmeldung P 33 07 213.2 beschrieben ist. Die Einführung der Kabelseele in den Vakuumbehälter 20 erfolgt ebenfalls über ein dichtendes Eintrittsrohr 23.The cable core 8, the transport direction of which is indicated by the arrow 9, is filled in a filling device 10 with a sealing compound which prevents leakage water from spreading along the cable core. The filling device consists of a sealing tube 11 serving the inlet of the cable core, the actual filling chamber 12 and an outlet sealing tube 13. The inlet sealing tube is connected to a vacuum container 20 in a vacuum-tight manner. Both sealing tubes are adapted to the core diameter and rotatable, as described in the earlier patent application P 33 07 213.2. The cable core is also introduced into the vacuum container 20 via a sealing inlet pipe 23.

Hintei dem Austrittsdichtrohr 13 ist ein beheizbarer Kalibriernippel 15 angeordnet. Unterhalb der Austrittsöffnung 14 des Austrittsdichtrohres 13 und des Kalibriernippels 15 befindet sich ein trogartiger Auffangbehälter 30, in dem auch die Zuführleitungen 33 und 34 für die Komponenten der Füllmasse münden. Mit dem Vakuum- und dem Auffangbehälter sind Fördereinrichtungen in Form von Doppelschneckenförderern 21 bzw. 31 integriert, die so ausgebildet sind, daß sie eine Druckdifferenz aufzubauen gestatten. Oberhalb des Doppelschneckenförderers 21 ist eine Strainerplatte 22 als Masseverteiler angeordnet. Der Masseverteiler ist über eine Leitung 24 und einer selbstdichtenden Förderpumpe 25 mit dem mit dem Auffangbehälter 30 verbundenen Doppelschneckenförderer 31 unter Zwischenschaltung einer Homogenisiereinrichtung 32 verbunden.A heatable calibration nipple 15 is arranged behind the outlet sealing tube 13. Below the outlet opening 14 of the outlet sealing tube 13 and the calibration nipple 15 there is a trough-like collecting container 30 in which the feed lines 33 and 34 for the components of the filling compound also open. With the vacuum and the collecting container conveyors in the form of twin screw conveyors 21 and 31 are integrated, which are designed so that they allow a pressure difference to build up. A strainer plate 22 is arranged above the twin-screw conveyor 21 as a mass distributor. The mass distributor is connected via a line 24 and a self-sealing feed pump 25 to the twin-screw conveyor 31 connected to the collecting container 30 with the interposition of a homogenizing device 32.

Der in dem Vakuumbehälter 20 angeordnete Doppelschneckenförderer 21 ist über eine selbstdichtende, druckaufbauende Förderpumpe 26 und eine Leitung 27 mit der Füllkammer 12 verbunden.The twin-screw conveyor 21 arranged in the vacuum container 20 is connected to the filling chamber 12 via a self-sealing, pressure-building feed pump 26 and a line 27.

Die Frischmasse wird über die Strainerplatte 22 in den Vakuumbehälter gefördert und dort entgast. In der Vakuumkammer wird ein Druck von etwa 0,1 bar aufrechterhalten. Der als Austragssystem dienende Doppelschneckenförderer 21 gewährleistet eine Druckerhöhung von etwa 0,9 bar, so daß die entgaste Frischmasse etwa mit Atmosphärendruck in die eigentliche Füllpumpe 26 gelangt. Hier wird die Füllmasse verdichtet und mit einem Druck von 10 bis 15 bar in die Füllkammer 12 gepreßt. Das gesamte Fördersystem ist druckdicht ausgebildet, damit die entgaste Masse an keiner Stelle Gas aufnehmen kann.The fresh mass is conveyed into the vacuum container via the strainer plate 22 and degassed there. A pressure of approximately 0.1 bar is maintained in the vacuum chamber. The twin-screw conveyor 21 serving as the discharge system ensures a pressure increase of approximately 0.9 bar, so that the degassed fresh mass reaches the actual filling pump 26 at approximately atmospheric pressure. Here the filling compound is compressed and pressed into the filling chamber 12 at a pressure of 10 to 15 bar. The entire conveyor system is designed to be pressure-tight so that the degassed mass cannot absorb gas at any point.
