Description

Bei den bisher bekannten Einrichtungen zur Kühlung von Waben "in Mischwerken ist das in das Innere der Walzen eingeführte Kühlrohr in vielem Fällen nur angebohrt, so daß das kalte Wasser nicht mit genügendem Druck austritt und daher nicht an die innere Walzenoberfläche gelangen kann, weshalb nur eine mangelhafte Kühlung erreicht wird. Beim Austritt des Wassers aus dem durchbohrten Kühlrohr entstehen an der Austrittsstelle Streuungen, die die Bildung eines geschlossenen Strahles verhindern.In the previously known devices for cooling honeycombs "in mixers In many cases, the cooling tube inserted into the inside of the rollers was only drilled, so that the cold water does not come out with sufficient pressure and therefore not to the inner one Roll surface can get, which is why only inadequate cooling is achieved. At the The water escapes from the pierced cooling pipe at the exit point Scatters that prevent the formation of a closed jet.

Nun sind zwar in die Walzen eingegossene Spiralen bekannt, die das Wasser direkt an die Kühlfläche bringen und diese gewissermaßen abbrausen. Die in die Walzen eingegossenen Kühlschlangen sind aber für schmiedeeiserne Walzen nicht verwendbar, und es besteht bei ihrer Verwendung die große Gefahr, daß sich die Löcher, die in die Kühlschlangen vorher eingebohrt sein müssen, schon beim Gießen, oder aber, wenn das Wasser nicht vollkommen rein ist, durch das Wasser selbst zusetzen und nicht gereinigt werden können.Now, spirals cast into the rollers are known, which feed the water directly bring the cooling surface and shower it off, so to speak. The ones poured into the rollers However, cooling coils cannot be used for wrought iron rolls, and when they are used, the there is a great risk that the holes, which have to be drilled into the cooling coils beforehand, already when watering, or if the water is not completely pure, through the Add water yourself and cannot be cleaned.

Bei den bislang gebräuchlichen Kühlvorrichtungen ist auch .ein vollkommenes Anfüllen der Walzen mit Kühlwasser durch die Entnahme des abfließenden Wassers in der Mitte der Walze nicht möiglich, so· daß eine vollständige Ausnutzung der inneren Kühlfläche nicht erreicht wird. Ein weiterer Übel-In the case of the cooling devices that have been used up to now, there is also a complete filling of the rollers with cooling water is not possible due to the removal of the draining water in the middle of the roller, so that a full utilization of the inner cooling surface is not achieved. Another evil

stand besteht darin, daß das aus den Ausbohrungen austretende Wasser sehr bald zur Abflußstelle gelangt und somit zum größten Teil für die Kühlung" unaiisgenutzt bleibt.
Um alle diese Übelstände zu beseitigen,, ist bei der vorliegenden Erfindung eine Düsenkühlung vorgesehen, bei welcher das Wasser mittels eines Kühlrohres, das durch die ganze Walze führt, durch eine oder mehrere auf die- j
The point is that the water emerging from the bores very soon reaches the drainage point and thus remains largely unused for cooling.
In order to eliminate all these inconveniences, a nozzle cooling system is provided in the present invention, in which the water by means of a cooling pipe that leads through the entire roller, through one or more to the j

ίο sem aufgesetzte Düsen in das Walzeninnere eingebracht wird, so daß das kalte Wasser die Wasserfüllung der Walzen in feinen Strahlen durchdringt und unbedingt an die Kühlfläche gelangen muß.ίο sem attached nozzles into the inside of the roller is introduced so that the cold water fills the rollers in fine Penetrates rays and must necessarily reach the cooling surface.

t5 Das an der inneren Walzenfläche erwärmte Kühlwasser wird durch ein in den Walzenkörper .eingeführtes, an sich bekanntes, gebogenes Abflußrohr an der höchsten Stelle in der Mitte der Walze entnommen und abgeführt. t5 The cooling water, which is heated on the inner roller surface, is fed into the roller body .Introduced, known, curved drain pipe at the highest point removed and discharged in the middle of the roller.

Durch die Düsenkühlung wird nicht nur eine wesentlich bessere Kühlung gegenüber der alten Kühlung, bei der nur einfach Löcher in die Kühlrohre gebohrt waren, erzielt, sondernThe nozzle cooling not only provides significantly better cooling compared to the old cooling, in which only holes were simply drilled in the cooling tubes, but

es wird auch der Wasserverbrauch für die Kühlung auf die Hälfte bis ein Drittel ermäßigt. the water consumption for cooling is also reduced by half to a third.

Das Eittführungsrohr ist durch die ganze Walze geführt, um mittels der Düse das Wasser an die zu kühlende Stelle zu bringen, Das gebogene Abflußrohr hat daher eine besondere Ausbildung erhalten, die erlaubt, beide Rohre in die innen erweiterte Walze einzuführen. The Eittleitrohr is led through the whole roller to by means of the nozzle the water to bring to the place to be cooled, the curved drainpipe therefore has a special Received training that allows both tubes to be inserted into the internally expanded roller.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung, und zwar bezeichnet α das Kühlrohr, b die aufgesetzten Düsen, c die Kühlfläche und d das gebogene Abflußrohr,The drawing illustrates an embodiment of the invention, namely α denotes the cooling pipe, b the attached nozzles, c the cooling surface and d the curved drain pipe,
