Description

Vakuumtrockenanlage mit kombiniertem Umlauf- und Belüftungshahn Bei Vakuumtrockenanlagen erfolgte die Abführung der im Kondensator niedergeschlagenen Flüssigkeit bisher dadurch, daß der Tropfraum des Kondensators mit dem Sammelraum durch einen Umlaufhahn verbunden war, wobei zum Ablassen des Kondensates dieser Umlaufhahn geschlossen, der Sammelraum belüftet werden mußte und erst dann das Kondensat abgelassen werden konnte. Die Verbindung des Sammelraumes mit dem Tropfraum nach dem Ablassen fand durch Bedienung der Hähne in umgekehrter Reihenfolge statt. Durch falsche Bedienung der verschiedenen Hähne wurde oft die ganze Anlage belüftet und damit der Trockenbetrieb gestört. Diese Bedienungsfehler schließt die neue Trocknungsanlage dadurch aus, daß am Kondensator Umlauf- und Belüfthahn in einem und demselben Armaturstück vereinigt und durch eine Schlitzführung in einer Verbindungsstange mit dem Ablaßhahn so gekuppelt sind, daß die richtige Reihenfolge in der Bedienung der Hähne sichergestellt ist.Vacuum drying system with combined circulation and ventilation tap The evacuation of the condensate precipitated in the condenser was carried out in a vacuum drying system Liquid so far in that the drip space of the condenser with the collecting space was connected by a circulation valve, this being used to drain the condensate Circulation valve closed, the collecting space had to be ventilated and only then the condensate could be drained. The connection of the collecting space with the drip space according to draining took place by operating the taps in reverse order. By Incorrect operation of the various taps often ventilated the whole system and so that the dry operation is disturbed. The new drying system closes these operating errors characterized in that the condenser circulation and ventilation valve in one and the same fitting piece united and through a slot guide in a connecting rod with the drain cock are coupled in such a way that the correct sequence in the operation of the taps is ensured is.

In der Zeichnung ist ein Ausführungsbeispiel der Anordnung gemäß der Erfindung dargestellt.The drawing shows an embodiment of the arrangement according to FIG Invention shown.

Das Kondensat fließt bei Betriebsstellung der Hahnarmatur von°dem Sammelboden f durch die Verbindungsleitung lt, g, i in den Sammelbehälter b. Zur Erzielung des Druckausgleiches zwischen Sammel- und Tropfraum gibt der obere Hahn gleichzeitig den Weg k, m, n frei. Der Ablaßhahn eist hierbei geschlossen.When the tap is in the operating position, the condensate flows from the collecting base f through the connecting line lt, g, i into the collecting container b. In order to achieve pressure equalization between the collecting and drip chambers, the upper tap simultaneously releases the path k, m, n . The drain cock is closed.

Soll der Ablaßhahn zur Abführung des Kondensates geöffnet werden, so gibt die Schlitzführung in der Verbindungsstange d erst dann die Möglichkeit dazu, wenn der obere Hahn umgelegt und damit das Vakuum abgesperrt ist. Durch den gleichzeitig frei gewordenen Weg k, 1, o, P wird der Sammelraum belüftet und so dem Kondensat die Möglichkeit gegeben, ruhig abzufließen.If the drain cock is to be opened to discharge the condensate, the slot guide in the connecting rod d only gives the opportunity to do so when the upper cock is turned over and the vacuum is thus shut off. Through the path k, 1, o, P that has become free at the same time, the collecting space is ventilated and the condensate is given the opportunity to flow off smoothly.

Bei Rückschaltung auf die Betriebsstellung gestattet die Verriegelung den Anschluß des Vakuums an den Sammelbehälter erst nach Abschluß des Ablaßhahnes und Absperrung des ins Freie führenden Belüftungskanals.When switching back to the operating position, locking is permitted the connection of the vacuum to the collecting container only after the drain cock has been closed and closing off the ventilation duct leading to the outside.
