Abstract

The invention relates to a cleaning device (9, 10) for a vertically mounted heat exchanger located in a buffer tank (1) for waste water. The cleaning device (9, 10) consists of a floatable material. The configuration is annular or polygonal with a polygonal recess and surrounds the heat exchanger (6). A brush strip or rubber lip is provided on the inside of the cleaning device (9, 10), such that said strip or lip contacts the outer wall of the heat exchanger (6). The altering fill level in the buffer tank (1) creates an up and down movement of the cleaning device (9, 10) and hence results in a cleaning of the heat exchanger (6).

Die Nachteile der hier angegebenen Erfindungen sind die aufwendige Konstruktion, sowie eine elektrische Steuerung. The disadvantages of the inventions specified here are the complex construction, as well as an electrical control.
Der Erfindung liegt somit die Aufgabe Zugrunde die Konstruktion und Steuerung möglichst einfach zu gestalten. The invention is thus the object of the design and control as simple as possible.
Die Aufgabe wird dadurch gelöst, dass die Reinigungsvorrichtung aus einem schwimmfähigen Material besteht, wodurch sich die Reinigungsvorrichtung immer auf der Abwasseroberfläche befindet. The object is achieved in that the cleaning device consists of a buoyant material, whereby the cleaning device is always on the wastewater surface.
Die Aufgabe wird dadurch gelöst, dass die Reinigungsvorrichtung eine ringförmige oder eine mehreckige Bauform aufweist, wobei in der Mitte der mehreckigen The object is achieved in that the cleaning device has an annular or polygonal shape, wherein in the middle of the polygonal
Reinigungsvorrichtung eine mehreckige Aussparung vorgesehen ist. Cleaning device is provided with a polygonal recess.
Die Reinigungsvorrichtung umschließt den Wärmetauscher, wodurch keine separaten Führungsschienen benötigt werden. The cleaning device encloses the heat exchanger, whereby no separate guide rails are needed.
Die Aufgabe wird dadurch gelöst, dass eine Bürstenleiste oder eine Gummilippe an der Innenseite der Reinigungsvorrichtung angebracht wird. The object is achieved in that a brush strip or a rubber lip is attached to the inside of the cleaning device.
Die Bürstenleiste beziehungsweise die Gummilippe berührt die Außenwand des Wärmetauschers, das bei einer aufwärts oder abwärts Bewegung der The brush strip or the rubber lip touches the outer wall of the heat exchanger, which in an upward or downward movement of the
Reinigungsvorrichtung zur Reinigung der Oberfläche des Wärmetauschers führt. Cleaning device for cleaning the surface of the heat exchanger leads.
Die Aufgabe wird dadurch gelöst, dass die Bürstenleiste oder die Gummilippe unterhalb der Abwasseroberfläche angebracht wird, wodurch sich wasserlösliche Stoffe selbstständig lösen können. Des Weiteren wird dadurch deren Reinigung mit der externen Zugabe von chemischen Reinigungsmitteln ermöglicht. The object is achieved in that the brush bar or the rubber lip is mounted below the sewage surface, which can solve water-soluble substances independently. Furthermore, this allows their cleaning with the external addition of chemical cleaning agents.
Die Dichte des schwimmfähigen Materials wird so gewählt, dass sie genug Auftrieb hat um die Reinigungsvorrichtung während der Befüllung des Pufferspeichers entgegen dem Reibungswiderstand der Bürstenleiste oder der Gummilippe nach oben zu drücken. The density of the buoyant material is chosen to have enough buoyancy to push the cleaner up against the frictional resistance of the brush bar or rubber lip during the filling of the buffer.
Die Größe der Reinigungsvorrichtung wird so gewählt, dass sie genug Gewicht hat um während der Entleerung des Pufferspeichers durch die Schwerkraft nach unten gezogen zu werden. The size of the cleaning device is chosen so that it has enough weight to be pulled down during the emptying of the buffer by gravity.
Die Figur 1 zeigt den Querschnitt einer Reinigungsvorrichtung für einen senkrecht angebrachten Wärmetauscher, der sich in einem Pufferspeicher für Abwasser befindet. 1 shows the cross section of a cleaning device for a vertically mounted heat exchanger, which is located in a buffer tank for wastewater.
