Description
Die Erfindung betrifft ein Drehfilte. nach dem Oberbegriff des Anspruchs 1 (vgl. DE-AS 12 23 344). Bei bekannten Drehfiltern dieser Bauart sind zwecks Abdichtung Stopfbüchsen oder andere Dichtungsanordnungen vorgesehen. Derartige Dichtungsanordnungen sind nicht nur aufwendig, sondern auch dem Verschleiß unterworfen und müssen dementsprechend in zeitlichen Abständen ausgewechselt werden. Ferner werden die im Bereich der Dichtungsanordnungen liegenden Wellen stark eingeschnürt, was nicht nur zu höheren Antriebsleistungen führt, sondern auch zu Verschleißerscheinungen auf der Welle selbst, so daß die Dichtungsanordnungen nicht einwandfrei auf der Welle sitzen. Letztere geben somit Anlaß zu Ärger und Betriebsstörungen, wenn sie nicht für genügende Abdichtung sorgen. The invention relates to a rotary filter. according to the generic term of claim 1 (see. DE-AS 12 23 344). In known rotary filters of this type are for the purpose of sealing Stuffing boxes or other sealing arrangements are provided. Such sealing arrangements are Not only expensive, but also subject to wear and tear and must accordingly be timed Be replaced at intervals. Furthermore, the waves lying in the area of the sealing arrangements strongly constricted, which not only leads to higher drive power, but also to signs of wear on the shaft itself, so that the sealing arrangements do not sit properly on the shaft. The latter give rise to annoyance and malfunctions if they do not provide sufficient sealing.
Der Erfindung liegt die Aufgabe zugrunde, den Aufwand an Material und Energie, den Verschleiß und die Störanfälligkeit der bekannten Dichtungsausführungen herabzusetzen.The invention is based on the problem of the effort in terms of material and energy, wear and tear and susceptibility to failure of the known seal designs to belittle.
Die Aufgabe wird erfindungsgemäß durch die Maßnahmen nach dem Kennzeichen des Anspruchs 1 gelöst Es wird somit bewußt eine geringfügige Leckage herbeigeführt, weil dabei jegliche Dichtungsanordnung an den Wellenenden entfallen kann, somit auch jeder Verschleiß des Dichtmittels und der Welle. Die durch die öffnungen in kleiner Menge fließende Suspension strömt bei tiefer liegendem Sammelbehälter (für die Suspension) diesem einfach zu und wird bei höher liegendem Sammelbehälter mittels einer Pumpe hinaufgepumpt. Dabei kann die Pumpe bei Erreichen eines be- es ' stimmten Suspensionsstandes in einem Sammelraum automatisch einschaltbar sein.The object is achieved according to the invention by the measures according to the characterizing part of claim 1 A slight leakage is thus deliberately brought about because any sealing arrangement is attached the shaft ends can be omitted, thus any wear on the sealant and the shaft. The through the openings in small quantities flowing suspension flows in the lower-lying collecting tank (for the Suspension) to this and is pumped up by means of a pump if the collecting tank is located higher. When a certain suspension level is reached, the pump can be in a collecting space be switched on automatically.
