Abstract

Die Anmeldung bezieht sich auf einen Schwimmbelüfter für Abwasserteiche und Belebungsbecken zur Eintragung von Luftsauerstoff mittels Druckluft in Bodennähe unter Verwendung wenigstens einer an Schwimmkörpern befestigten und mit Luftaustrittsöffnungen versehenen Luftversorgungsleitung. Die Bodenbelüfter für solche Anlagen sind aus Einzelteilen, üblicherweise aus mit Poren versehenen Rohrstücken aus Keramik zusammengesetzt und über einen Zuganker sowie mit den notwendigen Dichtelementen an den Stirnseiten zusammengeschraubt. Zur Verringerung des Herstellungsaufwandes und Vereinfachung der Montage vor Ort ist vorgesehen, die Luftversorgungsleitungen in Bodennähe schwebend zu installieren und an in Wasserspiegelhöhe schwimmenden Körpern aufzuhängen.The application relates to a swimming aerator for sewage ponds and aeration basins for introducing atmospheric oxygen by means of compressed air near the ground using at least one air supply line attached to floating bodies and provided with air outlet openings. The floor aerators for such systems are composed of individual parts, usually of ceramic tube pieces provided with pores, and are screwed together via a tie rod and with the necessary sealing elements on the end faces. To reduce the manufacturing costs and to simplify the assembly on site, the air supply lines are to be installed in a floating manner near the ground and to be suspended from bodies floating at water level.

Description

Die Erfindung betrifft eine Vorrichtung zur Belüftung von Abwasserteichen und Belebungsbecken mittels Druckluft, bestehend aus zumindest einer in Bodennähe angeordneten und mit Luftaustrittsöffnungen versehenen Luftversorgungsleitung.The invention relates to a device for the ventilation of sewage ponds and aeration basins by means of Compressed air, consisting of at least one arranged near the ground and provided with air outlet openings Air supply line.

Durch das DE-GM 19 54 879 ist bereits ein Belüfter zur Eintragung von Luftsauerstoff mittels Druckluft in Bodennähe eines Beckens unter Verwendung von Luftversorgungsleitungen, die an abv Schwimmkörper verwendbaren Rohren befestigt sind, !bekanntgeworden. Hierdurch wird die Möglichkeit geschaffen, elastische Rohrleitungen am Boden eines Gewässers zu installieren und zu Reparaturzwecken bzw. zum Umsetzen und dergleichen Maßnahmen aufschwimmen zu lassen, sobald das in den Befestigungsrohren befindliche Wasser herausgepreßt ist Die Rohre dienen dann als Schwimmkörper und heben die elastischen Rohrleitungen an die Wasseroberfläche. Ein teilweises Anheben bei sich ändernden Wassertiefen, insbesondere infolge Bodenablagerunge, ist jedoch nicht möglich.DE-GM 19 54 879 already has an aerator for the introduction of atmospheric oxygen by means of compressed air near the bottom of a basin using air supply lines, which are attached to pipes that can be used abv floats! This creates the possibility of installing elastic pipelines at the bottom of a body of water and for repair purposes or for repositioning and the like to float measures as soon as the water in the fastening pipes is squeezed out. The pipes then serve as floating bodies and raise the elastic pipes to the surface of the water. A partial increase when it changes However, water depths, especially as a result of soil deposits, are not possible.

Der Erfindung liegt die Aufgabe zugrunde, eine Belüftungsvorrichtung nach dem Gattungsbegriff des Anspruchs 1 so auszubilden, daß diese bei geringem Montageaufwand vor Ort sich verändernden Wassertiefen anpaßbar ist. Die Erfindung zur Lösung dieser Aufgabe zeichnet sich dadurch aus, daß die Luftversorgungsleitung schwebend installiert und an auf dem Wasser schwimmenden Körpern verstellbar aufgehängt ist. Vorzugsweise besteht die Aufhängung zwischen den auf dem Wasser schwimmenden Körpern und der Luftversorguiigsleitung aus höhenverstellbaren Tragelementen. Besonders günstig hierfür sind biegeschlaffe Elemente, beispielsweise Seile oder Ketten.The invention is based on the object of a ventilation device to form according to the generic term of claim 1 so that this with little installation effort is adaptable on site to changing water depths. The invention to solve this problem is characterized by the fact that the air supply line is installed floating and on the water floating bodies is adjustable. The suspension is preferably between the the water floating bodies and the air supply line made of height-adjustable support elements. Pliable elements are particularly favorable for this, for example ropes or chains.

Da in den Abwasserteichen der Schlamm bis zu zehn Jahren auf der Teichsohle abgelagert werden kann, muß die Möglichkeit bestehen, die Luftversorgungsleitung im Laufe der Jahre anzuheben. Dies ist bei der erfindungsgemäßen Vorrichtung sehr leicht möglich, da die Seile oder Ketten als Tragelemente zwischen Schwimmer und Luftversorgungsleitung verkürzt werden können. Since the sludge in sewage ponds can be deposited on the pond floor for up to ten years, it must there is an option to raise the air supply line over the years. This is with the invention Device very easily possible because the ropes or chains act as supporting elements between floats and air supply line can be shortened.

Bei allen sehr langen Luftversorgungsleitungen kann es zu einem Luftdruckabfall am Ende der Leitung und damit zu einer geringeren Belüftung dieses Abwasserbereiches kommen. Dieser Nachteil kann durch einfaches Verkürzen der Tragelemente zwischen Schwimmer und Luftversorgungsleitung beseitigt werden, so daß mit zunehmendem Druckabfall die entsprechenden Teile der Luftversorgungsleitung angehoben werden. Alle Bereiche des Abwasserteiches sind dadurch gleichmäßig belüftbar.All very long air supply lines can cause an air pressure drop at the end of the line and so that there is less ventilation of this wastewater area. This disadvantage can be solved by simply Shorten the supporting elements between the float and the air supply line are eliminated, see above that with increasing pressure drop, the corresponding parts of the air supply line are raised. This means that all areas of the sewage pond can be evenly ventilated.

Weiterhin sind bei der erfindungsgemäßen Vorrichtung keine Oberflächenbelüfter oder schwimmende Leitungen, sondern lediglich in größeren Abständen einzelne Schwimmer sichtbar, was zu einem optisch umweltfreundlichen Gesamtbild beiträgt und in vielen Fällen von den Betreibern von Abwasserteichen und Kläranlagen verlangt wird.Furthermore, there are no surface aerators or floating lines in the device according to the invention, but only individual swimmers are visible at larger distances, which is optically environmentally friendly Overall picture contributes and in many cases from the operators of sewage ponds and sewage treatment plants is required.
