Description
Vorrichtung zum Kühlen eingebuchteter Stellen an Drehrohröfen Es ist bereits eine Kühlung für eingebuchtete Stellen am Drehrohrofen und ähnlichen Einrichtungen vorgeschlagen worden, die beispielsweise zum Stauen des Gutes im* Innern oder für andere Zwecke dienen.Device for cooling indented areas on rotary kilns It is already a cooling for indented places on the rotary kiln and similar devices has been proposed, for example, to stow the goods inside or for serve other purposes.
Erfindungsgemäß wird diese Kühlung dadurch ausgeführt, daß Düsen oder Brausen mittels einer von dem Drehrohrumlauf abhängigen Steuervorrichtung angeordnet sind, mittels der sie in die sich nur über einen Teil des Umfanges erstreckenden Einbuchtungen eingeschoben und wieder zurückgezogen werden. Zweckmäßig werden dabei Abschlußmittel vorgesehen, welche den Zulauf des Kühlmittels zu den Düsen oder Brausen nach dem Zurückziehen aus den Einbuchtungen absperren.According to the invention this cooling is carried out in that nozzles or Showers arranged by means of a control device dependent on the rotating pipe circulation are, by means of which they extend only over part of the circumference Indentations are inserted and withdrawn again. Be useful in doing so Closing means provided, which the inlet of the coolant to the nozzles or showers after withdrawing from the indentations shut off.
Die Zeichnung stellt eine Ausführungsform der Erfindung dar.The drawing shows an embodiment of the invention.
Das Drehrohr i, dessen Lagerung hier nicht dargestellt ist und über dem sich eine Rohrleitung 2 befindet, besitzt Einschnitte oder Einbuchtungen 5, die nach außen offen sind.The rotary tube i, the storage of which is not shown here, and over which is a pipe 2, has incisions or indentations 5, that are open to the outside world.
Über diesen Einbuchtungen 5 sind Brausen .I angeordnet, die an Kolben 6 sitzen, welche auf dem vom Rohr 2 ausgehenden Rohrstutzen 7 verschiebbar sind und von einer im Takt des Drehrohrumlaufs sich drehenden Welle 8 mittels Hebeln 9 auf und ab geschoben werden. In der höchsten Stellung a eines der Kolben 6 wird die Auslauföffnung i o des Rohrstutzens 7 durch den im Kolben befestigten Schieber i i verschlossen, während sie bei Senkung des Kolbens 6 von diesem Schieber i i freigegeben wird.Above these indentations 5 showers .I are arranged on pistons 6 sit, which are displaceable on the pipe socket 7 extending from the pipe 2 and by a shaft 8 rotating in time with the rotary tube circulation by means of levers 9 can be pushed up and down. In the highest position a one of the pistons 6 is the outlet opening i o of the pipe socket 7 through the slide fastened in the piston i i closed, while when the piston 6 is lowered by this slide i i is released.
Die Einbuchtungen 5 am Drehrohr i sind gegeneinander versetzt angeordnet, und dementsprechend sind auch die Hebel 9 auf der Welle 8 gegeneinander verdreht befestigt.The indentations 5 on the rotary tube i are offset from one another, and accordingly the levers 9 on the shaft 8 are also rotated relative to one another attached.
Beim Umlauf des Drehrohres tauchen die Kolben 6 in die ihnen zugeordneten Einschnitte 5 hinein, sobald diese sich an der Oberseite des Drehrohres i befinden (s. Stellung' h), und.da hierbei zugleich die Mündung der zugehörigen Leitung 7 geöffnet wird, strömt das Kühlmittel (Luft oder Wasser) aus der betreffenden Düse oder Brause q. aus und bespült die Seitenwände des Einschnittes 5. Hierdurch wird eine kräftige Kühlwirkung erzielt, die sich besonders auf die der Flamme am meisten ausgesetzten Ouerwände des Einschnitts erstreckt. Um diese Kühlwirkung noch zu erhöhen und besonders bei Anwendung einer Kühlflüssigkeit ein zu schnelles Ablaufen von den bespülten Seitenflächen zu verhindern, können diese mit Rippen i4,besetzt werden.As the rotary tube rotates, the pistons 6 dip into their assigned Incisions 5 in as soon as they are on the top of the rotary tube i (see position 'h), and because here at the same time the mouth of the associated line 7 is opened, the coolant (air or water) flows out of the relevant nozzle or shower q. and flushes the side walls of the incision 5. This is A powerful cooling effect is achieved, which is particularly relevant to that of the flame the most exposed outer walls of the incision. To increase this cooling effect even more and especially when using a cooling liquid, too rapid drainage of To prevent the rinsed side surfaces, these can be covered with ribs i4.
