Description

Verfahren und Einrichtung zum Entlüften von Filtern.Method and device for venting filters.

Die Erfindung richtet sich auf Filter mit Entlüftungseinricht, ungen zu beiden Seiten des Fllterstoffes, und sie befaßt sich mit der Lösung der Aufgabe, die besonders bei wagerechten Filterschichten zwischen den Stützrippen und dem Filterkörper zurückbleib, enden Luftblasen zu beseitigen. Dies wird gemäß der Erfindung dadurch erreicht, daß das Filter vor Beginn des Filterns mit Wasser gefüllt und unter Unterdruck gesetzt wind, während zweckmäßig gleichzeitig die Entlüftungskanäle zur Ermöglichung einer gleichzeitigen Saugwirkung auf beiden Seiten des Filterstoffes mit der Saugleitung der Minderdruckhaltung in Verbindung stehen. The invention is directed to filters with venting devices on both sides of the filter material, and she is concerned with solving the problem especially with horizontal filter layers between the support ribs and the filter body left behind, ending up eliminating air bubbles. This is accomplished according to the invention achieves that the filter is filled with water and under vacuum before the start of filtering set wind, while expedient at the same time to allow the ventilation ducts simultaneous suction on both sides of the filter material with the suction line are related to low pressure maintenance.

Auf der Zeichnung ist die Erfindung durch ein Ausführungsleispiel veranschaulicht. In the drawing, the invention is illustrated by an exemplary embodiment illustrated.

Der Einlauf erfolgt in Richtung des Pfeiles, dter Auslauf in Richtung des Pfeiles b. c ist eine Strahlpumpe, durch die das Wasser in Richtung der Pfeile hindurchgetrieben wird. .d sind die Saugleitungen, die die Filtermitte bzw. den Filterrand mit der Strahlpumpe verbinden. Die in der Figur angegebenen Pfeile zeigen, wie die Luftblasen aus den Filterschichten zur Saugleitung hin aufsteigen können. Statt der Strahlpumpe kann naturgemäß jede andere zweckmäßige Saugvorrichtung Verwendung finden. The inlet takes place in the direction of the arrow, the outlet in the direction of the arrow b. c is a jet pump through which the water flows in the direction of the arrows is driven through. .d are the suction lines that the filter center or the Connect the filter edge to the jet pump. The arrows indicated in the figure show how the air bubbles can rise from the filter layers to the suction line. Instead of the jet pump, any other suitable suction device can of course be used Find.

Das Wesentliche beim Heraus saugen ist, daß im Filterinnern ein möglichst großer Unterdruck erzeugt wird, so daß die beim Füllen des Filters mit Flüssigkeit etwa hängengebliebenen Luftbläschen eine sehr starke Ausdehnung erfahren und dadurch mit Sicherheit aus dem Filter entfernt werden. The essential thing when sucking out is that as much as possible inside the filter large negative pressure is generated, so that when filling the filter with liquid Any remaining air bubbles experience a very strong expansion and thereby can be safely removed from the filter.
