Abstract

The water aeration system, using rigid and pref. plastic horizontal tubes with passage openings to deliver air through flat and slitted outer elastomeric bodies, uses the tubes (1) in a ring structure partially linked by cross tubes. A push fit joint is at least between some of the tubes to join them together. Several tube sections are covered by bodies (11) with slits (12). The edges of the cladding bodies are held rigidly against the tube by a surrounding frame, and pressed home by inserting mountings such as nails or staples and the like, without prior drilling. The air distribution bodies and mountings are fitted to the tubes of the ring layout and also to the cross tubes. The covering bodies are only fitted to the peak of the tubes. The tubes forming the ring and the cross tubes are composed of straight sections, curved sections and T-pieces. The nails pass through the frame (13), the edge of the covering body and penetrate the tube wall. The slits in the covering bodies run longitudinally. USE/ADVANTAGE - The tube system, for water aeration, is easily assembled and dismantled.

Description

Die Erfindung betrifft eine Wasserbelüftungseinrichtung, insb. für die Wasseraufbereitung und für Abwässer, mit starren, zum Zuleiten der Luft dienenden, im Wasser etwa waagerecht angeordneten Rohren und auf diesen Rohren aufliegenden, flachen Körpern mit feinen Schlitzen zum Einleiten von Luftblasen in das Wasser, wobei die Rohre im Bereich der flachen, aus einem Elastomer bestehenden Körpern mit Durchbrechungen versehen sind, über die Luft unter die Körper leit­ bar ist.The invention relates to a water ventilation device, especially for water treatment and waste water, with rigid, for air supply, in Water about horizontally arranged pipes and flat bodies resting on these tubes with fine slits for introducing air bubbles into the Water, the pipes in the area of the flat, from an elastomer body with openings are provided, conduct over the air under the body is cash.

Bei den bekannten Einrichtungen dieser Art sind die Rohre blindgeflanschte Abzweigungen von starren, rohrförmigen Luftzuleitungen, auf denen Abschnitte von geschlitzten Gummischlauchabschnitten angeord­ net sind. Zudem sind die Rohre untereinander und mit den Luftzuleitungen durch Flansche verbunden, die eine komplizierte Montage zur Folge haben.In the known devices of this type Pipes blind-flanged branches of rigid, tubular air ducts on which sections of slotted rubber hose sections arranged are not. In addition, the pipes are with each other and with the air supply lines connected by flanges that complicated assembly.

Der Erfindung liegt die Aufgabe zugrunde, Einrichtungen der eingangs erwähnten Art vorzuschlagen, die mit ein­ fachem technischem Aufwand wirkungsvoll nutzbar und schnell montierbar bzw. demontierbar sind.The invention has for its object facilities to propose the type mentioned at the outset, with a technical effort effectively  usable and quick to assemble or disassemble are.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgehen, daß die Rohre einen geschlossenen Ring bilden, von dem Teile durch Querrohre verbunden sind, daß zumindest zwischen einigen Rohren eine Steckverbindung vorgesehen ist und daß mehrere Rohrabschnitte oben mit einem streifenförmigen Körper abgedeckt sind, dessen Schlitze die Luft in das Wasser leiten.To solve this problem, the invention proceed that the pipes have a closed ring form, of which parts are connected by cross tubes are that at least between some pipes a connector is provided and that several Pipe sections above with a strip-shaped Bodies are covered, the slits of which are air into the water.

Diesem Ring wird die vorgespannte Luft an einer oder mehreren Stellen meist durch senkrechte Rohre zugeleitet, während der Ring und die Quer­ rohre an allen nur möglich Stellen Durchbrechungen haben, über denen die erwähnten geschlitzten streifenförmigen Körper angeordnet sind. Hierdurch ist ein erheblicher Luftdurchsatz möglich. Da zudem Steckverbindungen zwischen den Rohren des Ringes und/oder den Querrohren angebracht sind, kann eine Montage bzw. Demontage sehr schnell ausgeführt werden.The prestressed air on this ring becomes or more places mostly by vertical Pipes fed while the ring and the cross Pipes at all possible openings over which the slits mentioned above strip-shaped body are arranged. Hereby a significant air flow is possible. There also plug connections between the pipes of the Ring and / or the cross tubes are attached, can be assembled or disassembled very quickly be carried out.

In einfacher Weise werden auch die streifenförmigen Körper an ihren Rändern durch umlaufende Rahmen gehalten, die mittels eingeschossener Nägel oder Krampen an den Rohrkörpern verankert sind. Die streifenförmigen Körper umschließen also nicht die Rohre, wie dies bei den bekannten schlauch­ förmigen und nur durch Aufziehen montierbaren Schläuchen der Fall ist.In a simple way, the stripe-shaped Bodies at their edges thanks to surrounding frames held by means of shot nails or Staples are anchored to the pipe bodies. So the stripe-shaped bodies do not enclose the pipes, as is the case with the well-known hose shaped and mountable only by pulling Tubing is the case.

Die Ringform hat auch den Vorteil, daß eine gleichmäßige Speisung aller Rohrabschnitte und der erwähnten Querrohre gewährleistet ist.The ring shape also has the advantage that a uniform feeding of all pipe sections and  of the cross tubes mentioned is guaranteed.

Weitere Einzelheiten der Erfindung werden anhand der Zeichnung erläutert, in der ein Ausführungsbeispiel der Erfindung dargestellt ist. Es zeigenFurther details of the invention are based on the Drawing explained in the an embodiment the invention is shown. Show it

Fig. 4 eine Draufsicht auf einen Rohrabschnitt der Einrichtung gemäß Fig. 1 und Fig. 4 is a plan view of a pipe section of the device according to FIGS. 1 and

Fig. 5 einen Schnitt nach der Linie V-V von Fig. 4. Fig. 5 shows a section according to the line VV of Fig. 4.

Die Wasserbelüftungseinrichtung wird vorwiegend von hart eingestellten, im wesentlichen starren Rohren 1 aus Kunststoff zum Zuführen der vorgespannten Luft und einer Reihe von Luftzuführungsvorrichtungen, über die die Luft in feinen Bläschen in das Wasser gelangte gebildet.The water aeration device is predominantly formed by hard-set, essentially rigid pipes 1 made of plastic for supplying the prestressed air and a series of air supply devices via which the air entered the water in fine bubbles.

Die senkrechten Speiseleitungen 2 führen zu einem im wesentlichen waagerecht im Wasser, nahe oberhalb des Sohle des Wasserbeckens angeordneten Ring 3, der mit Schellen 4 od. dgl. am Grund 5 verankert ist.The vertical feed lines 2 lead to a ring 3 arranged essentially horizontally in the water, close above the bottom of the water basin, which is anchored to the base 5 with clamps 4 or the like.

Der im wesentlichen rechteckige oder quadratische Ring 3 hat mehrere einander parallele Querrohre 6. The essentially rectangular or square ring 3 has several mutually parallel cross tubes 6 .

Sowohl der Ring 3 als auch die Querrohre 6 bestehen aus zusammengesteckten Rohren bzw. Formteilen, so aus geraden Rohrabschnitten 7, Krümmern 8 und T- Stücken 9. Um sicherzustellen, daß eine luftdichte Verbindung unter Wasser gegeben ist, erfolgt gemäß Fig. 2 im Überlappungsbereich eine Abdichtung durch sog. O-Ringe 16 aus Gummi od. dgl. Diese Verbindung kann durch Zusammenstecken hergestellt und durch Auseinander­ ziehen wieder gelöst werden z. B. bei der Montage.Both the ring 3 and the transverse tubes 6 consist of tubes or molded parts put together, thus of straight tube sections 7 , elbows 8 and T-pieces 9 . To ensure that there is an airtight connection under water, a seal is made in the overlap region according to FIG. 2 by so-called O-rings 16 made of rubber or the like. B. during assembly.

Im Bereich der Luftzuführungsvorrichtungen haben die Rohre 1 Durchbrechungen 10 und oben auf dem Rohr 1 aufliegend einen sich in Rohrlängsrichtung erstreckenden Streifen 11 aus einem Elastomer z. B. Gummi, der mit einer Vielzahl durchgehender Schlitze 12 versehen ist, die sich unter dem Innendruck öffnen,feine Luft­ bläschen abgeben, sich aber wieder schließen, wenn der Außendruck überwiegt.In the area of the air supply devices, the tubes 1 have openings 10 and on top of the tube 1, a strip 11 extending in the longitudinal direction of the tube and made of an elastomer z. B. rubber, which is provided with a plurality of continuous slits 12 which open under the internal pressure, give off fine air bubbles, but close again when the external pressure prevails.

Zur luftdichten Befestigung der Streifen 11 sind hart eingestellte Rahmen 13 aus Kunststoff od. dgl. vorgesehen, die über eingeschossene Nägel 14 od. dgl. die Streifenränder fest an die Außenhaut der Rohre 1 an­ pressen. Die Rahmen 13 und die Streifen 11 können gemäß Fig. 4 in Einzelanordnung, aber auch z. B. bei den Querrohren 6 in Mehrfachanordnung installiert sein.For the airtight fastening of the strips 11 , hard-set frames 13 made of plastic or the like are provided, which press the strip edges firmly against the outer skin of the tubes 1 via inlaid nails 14 or the like. The frame 13 and the strips 11 can according to FIG. 4 in individual arrangement, but also z. B. be installed in the cross tubes 6 in multiple arrangement.

Es sei erwähnt, daß die Querrohre 6 Längen von etwa 4-6 m haben können. Die Einzelstreifen 11 sollten eine Länge von etwa 600-1000 mm haben.It should be mentioned that the cross tubes can have 6 lengths of about 4-6 m. The individual strips 11 should have a length of approximately 600-1000 mm.

Wie aus Fig. 4 erkennbar ist, ist für die Schlitze 12 ein Feld 15 vorgesehen, das vor den Durchbrechungen 10 endet, die somit von einem nicht perforierten Abschnitt des dünnen Streifens 11 überdeckt sind. As can be seen from FIG. 4, a field 15 is provided for the slots 12 , which ends in front of the openings 10 , which are thus covered by a non-perforated section of the thin strip 11 .

Die Ringform der Rohrleitungen sichert eine gleichmäßige Luftzufuhr zu allen Luftzuführungsvorrichtungen, die in großer Anzahl auf allen gerade verlaufenden Rohrabschnitten vorgesehen werden können. Die Anordnung und Ausbildung der Streifen 11 ist deshalb besonders günstig, weil sie im Zenit der Rohre 1 angeordnet werden, also an einer Stelle, an der die Luftbläschen besonders günstig abströmen.The ring shape of the pipes ensures a uniform air supply to all air supply devices, which can be provided in large numbers on all straight pipe sections. The arrangement and design of the strips 11 is particularly favorable because they are arranged at the zenith of the tubes 1 , that is to say at a point at which the air bubbles flow out particularly favorably.
