Description
Behälter zum Auskristallisieren von Salzen aus Lösungen durch Abkühlung.Container for crystallizing salts from solutions by cooling.
Zum Auskristallisieren von Salzen aus Lösungen werden vielfach Behälter verwendet, in welchen Isühlschlangen angebracht sind. Bei diesen Einrichtungen ist es unvermeidlich, daß die ausgeschiedenen Kristalle auch die Rohrschlangen belegen, so daß diese allmählich derart mit Kristallen bedeckt sind, daß die Kälteübertragung hierunter leidet. Containers are often used to crystallize salts from solutions used, in which cooling snakes are attached. With these bodies is it is inevitable that the precipitated crystals also occupy the coils, so that they are gradually covered with crystals in such a way that the cold transfer suffers from this.
Man hat nun versucht, diesen nachteil dadurch zu beseitigen, daß man die auf den Rohrschlangen abgesetzten Kristalle durch komprimierte Luft wegblies. Zu diesem Zweck werden unter den Rohrschlangen halbkreis- oder kreisförmige Rohrleitungen für die komprimierte Luft mit entsprechenden Austrittsdüsen vorgesehen. Diese Einrichtung ist an sich sehr wirksam, hat aber den Nachteil, daß bei etwaigem Aussetzen des Luft. druckes die Lösung in die Luftdüse eintritt und damit den weiteren Betrieb stört. Attempts have now been made to eliminate this disadvantage in that the crystals deposited on the pipe coils are blown away by compressed air. For this purpose, semicircular or circular pipes are placed under the pipe coils provided for the compressed air with appropriate outlet nozzles. This facility is very effective in itself, but has the disadvantage that if the Air. pressure, the solution enters the air nozzle and thus further operation disturbs.
Hier setzt nun die vorliegende Erfindung ein. This is where the present invention comes in.
Ihr Wesen besteht darin, daß diese Luftaustrittsdüsen mit Lippenventilen verschlossen sind, die im Betriebe unter dem Luft druck sich öffnen, beim Aussetzen des Luftdruckes aber infolge der elastischen Beschaffenheit des Stoffes, aus welchem sie hergestellt sind, wie Gummi o. dgl., sich selbsttätig schließen und somit den Eintritt der Flüssigkeit in die Druckluftleitung verhindem. Their essence is that these air vents with lip valves are closed, which open under the air pressure in operation when exposed of the air pressure, however, due to the elastic nature of the material from which it is made they are made, such as rubber o. The like., close automatically and thus the Prevent the liquid from entering the compressed air line.
Die Vorrichtung gemaß vorliegender Erfindung ist in der Zeichnung dargestellt, und zwar zeigt Abb. 1 einen senkrechten Querschnitt, Abb. 2 eine Draufsicht, Abb. 3 die Lippenventile bzw. deren Anordnung und Abb. 4 eine Draufsicht auf das Lippenventil. The device according to the present invention is shown in the drawing shown, namely Fig. 1 shows a vertical cross-section, Fig. 2 is a plan view, Fig. 3 the lip valves and their arrangement and Fig. 4 is a plan view of the Lip valve.
In einem in der Zeichnung nicht dargestellten Behälter sind die Kühlschlangen a angeordnet. Unter der untersten Kühlschlange sind die Leitungen b für die Druckluft vorgesehen. Sie sind im vorliegenden Fall in der Zeichnung (Abb. 2) kreisförmig dargestellt. The cooling coils are in a container not shown in the drawing a arranged. Lines b for the compressed air are under the lowest cooling coil intended. In the present case in the drawing (Fig. 2) they are circular shown.
Auf den Leitungen sitzen die Düsen c (Abb. 3), aus welchen die Druckluft- austritt. Diese Düsen werden durch die Lippenventiled verschlossen, die in ihrer obersten Kante eine öffnung (Abb. 4) haben, welche sich, wie erwählat, nur unter Luftdruck öffnet und beim Aussetzen des Luftdruckes infolge der elastischen Beschaffenheit des Materials sich selbsttätig wieder schließt.The nozzles c (Fig. 3), from which the compressed air exit. These nozzles are closed by the lips ventiled in their top edge have an opening (Fig. 4), which, as selected, is only below Air pressure opens and when the air pressure is exposed due to the elastic nature of the material closes again automatically.
