Description
Die Erfindung betrifft eine Vorrichtung zum Begasen einer Flüssigkeit, insbesondere zum Belüften von Abwasser, nach dem Oberbegriff des Anspruchs 1 sowie ein Klärbecken nach dem Oberbegriff des nebengeordneten Patentanspruchs.The Invention relates to a device for gassing a liquid, in particular for aerating wastewater, according to the preamble of claim 1 and a clarifier according to the preamble of the independent claim.
Die
Aufgabe der vorliegenden Erfindung ist es, die Kosten für Installation und Wartung einer solchen Vorrichtung zu reduzieren, und darüber hinaus den Wirkungsgrad einer solchen Vorrichtung zu verbessern.task The present invention is the cost of installation and maintenance of such a device, and above in addition to improve the efficiency of such a device.
Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 sowie durch ein Klärbecken mit den Merkmalen des nebengeordneten Patentanspruchs gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in Unteransprüchen angegeben. Darüber hinaus finden sich für die Erfindung wichtige Merkmale in der nachfolgenden Beschreibung und in der Zeichnung, wobei diese Merkmale sowohl in Alleinstellung als auch in beliebigen Kombinationen für die Erfindung wichtig sein können, ohne dass hierauf nochmals explizit hingewiesen wird.These The object is achieved by a device having the features of the claim 1 as well as through a clarifier with the characteristics of the sibling Patent claim solved. Advantageous developments of Invention are specified in subclaims. About that In addition, find important features for the invention in the following description and in the drawing, these Features both alone and in any combination may be important to the invention without This is again explicitly pointed out.
Der Aufbau der erfindungsgemäßen Vorrichtung ist geradezu minimalistisch einfach: Im Grunde genügt eine mit Mikroöffnungen versehene Membran, die direkt, also ohne Zwischenschaltung irgendeines Rohres oder von Trägerplatten, auf dem Boden des Beckens befestigt wird. Im allereinfachsten Falle wird also die Unterseite des Kanals durch den Boden des Beckens gebildet, wohingegen die Oberseite des Kanals durch die Membran gebildet wird. Die Installation eines solchen Kanals erfordert nur einen sehr geringen Aufwand, die Wartung, beispielsweise ein Austausch, ist äußerst einfach durchzuführen und die Herstellkosten sind sehr niedrig. Darüber hinaus ist die Höhe über dem Boden des Beckens, in der die Luftbläschen aus den Mikroöffnungen austreten, nur äußerst gering, so dass das in dem Becken vorhandene Fluid quasi vollständig von der austretenden Luft beaufschlagt wird. Dank der erfindungsgemäßen Vorrichtung wird daher ein großer Wirkungsgrad bei der Reinigung des in dem Becken vorhandenen Abwassers erzielt.Of the Structure of the device according to the invention is downright minimalistically simple: basically one with micro openings is enough provided membrane directly, so without any intervening Pipe or support plates, on the bottom of the basin is attached. In the simplest case, so the bottom is of the channel formed by the bottom of the basin, whereas the top of the channel is formed by the membrane. The installation of a Such a channel requires very little effort, maintenance, for example, an exchange is extremely easy perform and the production costs are very low. About that in addition, the height is above the bottom of the basin, in the air bubbles from the micro-openings leak, only extremely small, so that in the Basin existing fluid almost completely from the exiting Air is applied. Thanks to the invention Device will therefore be a great efficiency in the Cleaning the existing wastewater in the basin achieved.
In einer ersten Weiterbildung wird für den stirnseitigen Abschluss ein Formteil vorgeschlagen, welches beispielsweise als Tiefziehteil oder Spritzgussteil in Form einer Halbschale, hergestellt werden kann. Möglich ist auch eine Ausgestaltung des Formteils aus dem gleichen Material wie die Membran, jedoch mit abgerundeten Ecken, um die entstehenden Kräfte optimal aufnehmen zu können. Damit wird die Dichtigkeit am stirnseitigen Ende des Kanals erhöht, und die Lebensdauer wird verbessert, da Spannungsspitzen durch die vorzugsweise abgerundete Form des Formteils sowie Falten vermieden werden.In a first training is for the frontal degree proposed a molding, which, for example, as a deep-drawn part or injection molded part in the form of a half-shell, can be produced. Also possible is an embodiment of the molding from the same material as the membrane, but with rounded corners, to be able to absorb the resulting forces optimally. Thus, the tightness at the front end of the channel is increased, and the life is improved because voltage spikes by the preferably rounded shape of the molding as well as wrinkles are avoided.
Durch die gemäß einer anderen Weiterbildung vorgesehene Bördelung wird im Zusammenwirken mit der vorgeschlagenen Klemmschiene eine sichere Befestigung unmittelbar am Boden des Beckens ermöglicht, die darüber hinaus preiswert herstellbar und leicht realisierbar ist.By provided in accordance with another development Flanging will work in conjunction with the proposed Clamping rail a secure attachment directly to the bottom of the pool allows, in addition, inexpensive to produce and is easily realizable.
Zur Einbringung des Gases in den Kanal eignet sich besonders gut ein Anschlussstutzen in Form eines Formteils, wiederum beispielsweise eines Spritzguss- oder Tiefzieh- oder Drehteiles. Hierdurch ist eine dichte und zuverlässige Anbindung des Kanals an die Gasversorgung möglich.to Insertion of the gas into the channel is particularly well suited Connecting piece in the form of a molding, in turn, for example an injection-molded or thermoformed or turned part. This is a dense and reliable connection of the canal to the Gas supply possible.
Ein breiter flacher Querschnitt des Kanals, beispielsweise mit einem Seitenverhältnis von mindestens 1 zu 10, reduziert das Volumen und die Höhe, in der die Mikroöffnungen angeordnet sind, verbessert also letztlich den Wirkungsgrad der Vorrichtung. Die lang gestreckte Form des Kanals reduziert die Anzahl der für die Belüftung des gesamten Beckens erforderlichen Kanäle und somit die gesamten Installationskosten.One wide flat cross section of the channel, for example with a Aspect ratio of at least 1 to 10, that reduces Volume and the height at which the micro-openings are arranged, so ultimately improves the efficiency of Contraption. The elongated shape of the channel reduces the number necessary for the ventilation of the entire pool Channels and thus the total installation costs.
Die Anforderungen an den Boden des Beckens können durch eine auf dem Boden des Beckens aufliegende Folie reduziert werden, die mit der Membran fluiddicht zusammenwirkt. Insbesondere können Folie und Membran miteinander verschweißt oder verklebt oder vernäht sein, wodurch eine Art geschlossener Schlauch hergestellt wird, der sehr einfach zu verlegen ist.The Requirements for the bottom of the basin can be achieved by a be reduced to the bottom of the pelvis resting foil, the interacts fluid-tight with the membrane. In particular, you can Foil and membrane welded or glued together or sewn, creating a kind of closed hose produced, which is very easy to install.
Ebenfalls zur Verbesserung des Wirkungsgrads dient eine Dichtung, die, je nach Art der Installation, zwischen Folie und Membran oder zwischen Membran und Boden angeordnet ist.Also to improve the efficiency is a seal that, depending depending on the type of installation, between foil and membrane or between membrane and floor is arranged.
Um auch hohe Druckdifferenzen zu beiden Seiten der Membran zuverlässig und für eine lange Zeit aushalten zu können, kann eine Gewebearmierung vorgesehen sein, durch die die Zugfestigkeit der Membran verbessert wird. Dem steht nicht entgegen, dass die Membran vorzugsweise gummielastische Eigenschaften aufweist, da dies zumindest in bestimmten Richtungen beispielsweise durch eine entsprechende Orientierung der Gewebearmierung erreichbar ist. Denkbar ist auch, die Armierung so auszugestalten, dass zunächst eine gummielastische Ausdehnung der Membran möglich ist, die dann durch ein Wirksamwerden der Gewebearmierung gestoppt wird.In order to be able to withstand high pressure differences on both sides of the membrane reliably and for a long time, a fabric reinforcement can be provided, by which the tensile strength of the Membrane is improved. This does not preclude that the membrane preferably has rubber-elastic properties, since this can be achieved at least in certain directions, for example by a corresponding orientation of the fabric reinforcement. It is also conceivable to design the reinforcement in such a way that initially a rubber-elastic expansion of the membrane is possible, which is then stopped by the tissue reinforcement becoming effective.
Als Material eignen sich für die Membran insbesondere PVC sowie gummielastische Materialien, beispielsweise EPDM, Silikon und/oder Polyurethan.When Material are suitable for the membrane in particular PVC as well elastomeric materials, such as EPDM, silicone and / or Polyurethane.
Durch eine Entwässerungsleitung kann Kondenswasser aus dem Innenraum des Kanals abgeführt werden, wodurch vor allem Probleme bei der Inbetriebnahme nach einer längeren Stillstandszeit vermieden werden.By a drainage pipe can drain water from the interior the channel to be dissipated, which mainly causes problems avoided during commissioning after a long downtime become.
