Abstract
Description
Die Erfindung betrifft eine Einrichtung nach dem Oberbegriff des Anspruches 1 und ein Verfahren nach dem Anspruch 12.The The invention relates to a device according to the preamble of the claim 1 and a method according to claim 12.
Eine Einrichtung nach dem Oberbegriff des Anspruches 1 ist aus der US-PS 5,895,617 bekannt. Irgendwelche besonderen Maßnahmen zum Anfahren der Einrichtung sind hieraus nicht bekannt. Wenn bei derartigen Einrichtungen Extruder und Unterwasser-Granulier-Vorrichtungen mit hoher Produktionsleistung von primär Polyolefinen, in der Größenordnung von mindestens 40 t/h, vorgesehen sind, dann taucht das Problem auf, dass in einer langen Förder-Leitung von mindestens 40 Metern, in der Regel aber mindestens 100 bis 1000 Metern große Wassermengen beschleunigt werden müssen und die Granulier-Vorrichtung zugeschaltet werden muss. In der Praxis sind derartige Wasserkreisläufe relativ klein, wobei bei den erwähnten hohen Produktionsleistungen nur sehr kurze hydraulische Förderungen von wenigen Metern vorgesehen sind. Bei kleinen Produktionsleistungen sind auch schon Förder-Leitungen von bis zu 100 Metern Länge realisiert worden, wobei aber wegen der geringen Produktionsleistung die zu beschleunigenden Wassermengen begrenzt waren. Mögliche Rückströmungen von Wasser aus der Förder-Leitung in die Granulier-Vorrichtung wurden hierbei in Kauf genommen. Für große Produktionsleistungen und lange Förder-Leitungen ist dies aber nicht mehr vertretbar.A Device according to the preamble of claim 1 is known from US-PS 5,895,617. any special measures to start the device are not known from this. If at Such devices include extruders and underwater pelletizers with high production output of primarily polyolefins, on the order of magnitude of at least 40 t / h, then the problem appears on that in a long conveyor pipe of at least 40 meters, but usually at least 100 to 1000 Meters tall Water quantities must be accelerated and the granulation device must be switched on. In practice, such water cycles are relative small, with the mentioned high production rates only very short hydraulic deliveries are provided by a few meters. For small production are already conveyor lines of up to 100 meters in length realized, but because of the low production capacity the were limited to accelerating amounts of water. Possible backflows from Water from the conveyor pipe in the granulation device were accepted here. For large production outputs and long conveyor lines But this is no longer justifiable.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Einrichtung der gattungsgemäßen Art so weiterzubilden, dass auch bei großen Produktions leistungen und/oder sehr langen Förder-Leitungen zuverlässig ein störungsfreies Anfahren der Granulier-Vorrichtung ereicht wird.Of the Invention is therefore based on the object, a device of generic type so educate that even with large production services and / or very long conveyor lines reliable a trouble-free Approaching the granulating device is reached.
Diese Aufgabe wird bei einer Einrichtung nach dem Oberbegriff des Anspruches 1 durch die Merkmale im Kennzeichnungsteil des Anspruches 1 gelöst. Der Anspruch 12 gibt das Verfahren zum Anfahren dieser Einrichtung wieder. Kern der Erfindung ist, dass die Granulier-Vorrichtung und die Förder-Leitung erst zusammengeschaltet werden, wenn nach dem Füllen der Förder-Leitung auch die Granulier-Vorrichtung mit Wasser gefüllt ist, so dass also ein Rückströmen von Wasser aus der Förder-Leitung in die Granulier-Vorrichtung beim Anfahren vermieden wird. Der Übergang vom Füll-Betrieb zum Granulier-Betrieb ist ohne Anhalten der Pumpe möglich. Durch die erfindungsgemäßen Maßnahmen ist weiterhin erreicht, dass ein relativ kleiner Ausgleichs-Tank ausreichend ist, da dieser im Wesentlichen nur die Wassermenge enthalten muss, die zum Füllen der Granulier-Vorrichtung erforderlich ist.These Task is in a device according to the preamble of the claim 1 solved by the features in the characterizing part of claim 1. Of the Claim 12 is the method for starting this device again. The core of the invention is that the granulating device and the conveying line only be interconnected when after filling the conveyor line and the granulation device filled with water is, so that is a backflow of Water from the production line in the granulating device is avoided when starting. The transition from the filling operation for granulation operation is possible without stopping the pump. By the measures of the invention is still achieved that a relatively small equalization tank is sufficient, since these contain essentially only the amount of water that needs to be filled the granulating device is required.
