Description

Die Erfindung betrifft eine Vorrichtung zum Abziehen von Schmelzen, insbesondere organischen Schmelzen und Kunststoffen, mit Hilfe von flüssigen Stoffen, die einerseits als Kühlmittel und andererseits als Saugmittel für den Abfluß der Schmelze dienen und deren Geschwindigkeit und/oder Menge regelbar ist, wobei die Schmelze zunächst in einen im wesentlichen parallel zur Abflußrichtung der Schmelze gerichteten Kühl- und Saugmittelstrom führbar und gemeinsam mit dem Kühl- und Saugmittel abführbar ist und wobei ein Gießer mit einem Hauptventil versehen ist und einen allseitig mit Blechen umgebenen stumpfen Verteilerkegel aufweist, der radial in der Kegelneigung eine große Anzahl einzelner Verteilerrohre aufweist, die am Ende etwa parallel zur Achse des Verteilerkegels hin gebogen in mittels einzeln oder gemeinsam zu betätigender Ventile absperrbare Ausiauföffnungen eines Ringes münden.The invention relates to a device for drawing off melts, in particular organic ones Melts and plastics, with the help of liquid substances, on the one hand as a coolant and on the other hand serve as suction means for the outflow of the melt and its speed and / or quantity can be regulated is, wherein the melt is initially directed in a direction substantially parallel to the outflow direction of the melt The flow of coolant and suction medium can be guided and can be discharged together with the coolant and suction medium and wherein a caster is provided with a main valve and one surrounded on all sides with metal sheets having obtuse distribution cone, the radial in the cone inclination a large number of individual distribution pipes has, bent at the end approximately parallel to the axis of the distributor cone in by means of individually or valves to be operated together open to shut-off openings of a ring.
Der Erfindung liegt die Aufgabe zugrunde, das den Abzugsdüsen von oben im Überlauf z.ugeführte Kühlwasser, auch Oberwasser genannt, gleichmäßig und ohne Wirbel den Abzugsdüsen zuzuführen. Dies geschieht erfindungsgemäß dadurch, daß für die Zuführung des Kühlmittels zu jedem Schmelzestrang eine Mehrzahl von Abzugsdüsen angeordnet ist und dcß alle Abzugsdüsen aus einem diese umgebenden Sieb, durch das das Kühlmittel hochdrückbar ist, nach oben herausragen.The invention is based on the task of guiding the exhaust nozzle from above in the overflow Cooling water, also called upstream water, is supplied to the exhaust nozzles evenly and without eddies. this happens according to the invention that for the supply of the coolant to each melt strand a plurality of draw-off nozzles is arranged and dcß all draw-off nozzles from a surrounding them The sieve, through which the coolant can be pushed up, protrudes upwards.
Das hochsteigende Kühlwasser (Oberwasser) muß aiso beim Hochsteigen um die Abzugsdüsen im gesamten Bereich um jede Abzugsdüse herum die Siebfläche durchsetzen, wodurch dem Kühlwasser ein uleichmäßiger Widerstand entgegengesetzt wird und "eine möglicherweise vorher vorhandene Turbulenz weitgehend beseitigt wird. Da der gesamte Raum zwischen und um die Abzugsdüsen für die Zuführung des Kühlwassers ausgenutzt wird, steht diesem also ein relativ großer Querschnitt zur Verfügung, was ebenfalls einer Wirbelbildung entgegenwirkt. Darüber hinaus wird durch die Siebfiäche eine Filter1 mg des Kühlwassers erreicht. Eventuelle Verunreinigungen werden hierdurch ausgeschieden.The rising cooling water (head water) must penetrate the sieve surface in the entire area around each exhaust nozzle when rising up around the exhaust nozzle, whereby the cooling water is opposed to an inadequate resistance and "any previously existing turbulence is largely eliminated. Since the entire space between and around If the outlet nozzle is used for the supply of the cooling water, a relatively large cross-section is available, which also counteracts the formation of vortices. In addition, a 1 mg filter of the cooling water is achieved through the screen surface.
Eine vorteilhafte Weiterbildung besteht darin, daß das Sieb nach oben über die Abzugsdüsen abnehmbar ist. Die Reinigung des Siebes stellt dcmit kein Problem dar.An advantageous further development consists in the fact that the screen can be removed upwards via the extraction nozzles is. Cleaning the sieve is no problem.
In den Figuren ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigtIn the figures is an embodiment of the invention shown. It shows
F i g. 1 einen Querschnitt durch ein Abzuggerät nach Γ i g. 2,F i g. 1 shows a cross section through a trigger device according to Γ i g. 2,
Fig.2 einen Ausschnitt einer Draufsicht auf ein Abzuggerät.2 shows a detail of a plan view of a Trigger device.
Nach dem in F i g. 1 dargestellten Querschnitt ist das Gehäuse des Abzuggerätes mit 1 bezeichnet, in dem die Abzugsdüsen 2 gegen einen nicht dargesteli ten Schmelzflußverteiler ragend befestigt sind.After the in F i g. 1, the housing of the trigger device is denoted by 1, in FIG which the exhaust nozzles 2 are attached protruding against a not dargesteli th melt flow distributor.
Auf das Gehäuse 1 ist das das Oberwasser begrenzende Gehäuseteil 3 in Form eines Ringes mit Flansch 3' festgeschraubt. Dieses Gehäuseteil 3 hat innen einen Ringbund 4, auf dem das mit Ausstanzungen 5 versehene Sieb 6, übergeschoben über die Abzugsdüsen, zur Auflage kommt. Zum Ausheben des Siebes 6 über die Abzugsdüsen 2 sind an demselben Griffösen 7 vorgesehen. Das Sieb 6 könnte auch mittels Drahthaken abgehoben werden.On the housing 1, the housing part 3 delimiting the upper water is in the form of a ring Flange 3 'screwed tight. This housing part 3 has an annular collar 4 on the inside, on which the punched-out parts 5 provided sieve 6, pushed over the extraction nozzles, comes to rest. For digging of the sieve 6 via the extraction nozzles 2 are provided on the same handle eyelets 7. The sieve 6 could also can be lifted off by means of a wire hook.
Aus der Draufsicht gemäß F i g. 2 ersieht man deutlich, daß das Sieb als durchgehende, alle Abzugsdüsen umgebende Siebfläche ausgebildet ist, so daß also das Oberwasser (Kühlwasser) mit relativ großem Querschnitt neben den Abzugsdüsen 2 durch das Sieb6 hochsteigen kann. Die in Fig. 1 eingezeichneten Pfeile zeigen dabei die Zuführungsrichtung des Oberwassers an.From the top view according to FIG. 2 you can see clearly that the sieve as a continuous, all exhaust nozzles surrounding screen surface is formed, so that the upper water (cooling water) with a relatively large Cross-section next to the extraction nozzles 2 through the sieve 6 can rise. The ones shown in FIG Arrows indicate the direction in which the headwater is fed.
