Abstract
Die Erfindung betrifft eine Vorrichtung zum Aufkonzentrieren einer von einer Differenzialkolbenpumpe durch eine Konzentriereinrichtung gepumpten Flüssigkeit, die als Konzentrat unter Restdruck den wenigstens einen Differenzialkolben beim Fördertakt assistierend direkt beaufschlagt, wobei die Differenzialkolbenpumpe als Radialkolbenpumpe ausgebildet ist und die Differenzialkolben von einem Exzenter auf einer Antriebswelle der Radialkolbenpumpe angetrieben werden, die eine Steuerventileinrichtung zum Zu- und Abführen der Fluide betätigt und die Steuerventileinrichtung in Form wenigstens eines rotierenden Ventilelementes (7b, 8b; 70b) ausgebildet ist, das mit der Antriebswelle (2) verbunden ist.The invention relates to a device for concentrating a pumped by a differential piston pump by a concentrating liquid, which acts as a concentrate under residual pressure the at least one differential piston assisting directly Fördertakt, wherein the differential piston pump is designed as a radial piston pump and the differential piston of an eccentric on a drive shaft of the radial piston pump driven by a control valve means for supplying and discharging the fluids and the control valve means in the form of at least one rotating valve element (7b, 8b, 70b) is formed, which is connected to the drive shaft (2).
Description
Die Erfindung betrifft eine Vorrichtung zum Aufkonzentrieren einer Flüssigkeit nach dem Oberbegriff des Anspruchs 1.The The invention relates to a device for concentrating a liquid according to the preamble of claim 1.
Eine
Vorrichtung dieser Art ist aus
Der Erfindung liegt die Aufgabe zugrunde, die Steuerung der Vorrichtung zu verbessern.Of the Invention is based on the object, the control of the device to improve.
Dies wird erfindungsgemäß dadurch erreicht, dass die Steuereinrichtung durch wenigstens ein rotierendes Ventilelement ausgebildet wird, das mit der Antriebswelle der Radialkolbenpumpe verbunden ist. Durch die Drehbewegung des Ventilelementes, beispielsweise einer Steuerscheibe, ist eine verschleißarme Steuerung ohne nennenswerten Energieaufwand möglich.This is inventively achieved in that the Control device by at least one rotating valve element is formed, with the drive shaft of the radial piston pump connected is. By the rotational movement of the valve element, for example a control disc, is a low-wear control possible without significant energy expenditure.
