Membra; ibe luft er BeschreibungMembra; ibe luft er Description
Die Erfindung betrifft einen Mervbranbelüfter für ein Wasserbecken oder ein Klärbecken mit einem Aufnahmeteller, der einen Druckluftanschluß aufweist und von einer gelochten Membran überspannt ist, die bei dem Druckluftanschluß eine ungelochte Teil fläche aufweist.The invention relates to a membrane aerator for a water basin or a clarification basin with a receiving plate, which has a compressed air connection and is covered by a perforated membrane, which has an unperforated partial surface at the compressed air connection.
Derartige Membran-Punktbelüfter sind marktbekannt. Sie sind am Boden eines Wasser- oder Klärbeckens installiert. Bei der Zuleitung von Druckluft wölbt sich die Membran auf. Dabei öffnen sich die Löcher· der Membran, so daß Luft in das Wasser eintritt. Beim Abschalten der Druckluft legt sich die Membran unter dem statischen Druck des Wassers auf den Aufnahmeteller. Dabei schließen sich die öffnungen. Die ungelochte Teilfläche deckt den Druckl uftanschltiß ab. Damit ist vermieden, daß Schlamm und Bakterien in die öffnungen und den Druckluftanschluß eintreten.Such membrane point aerators are well-known on the market. They are installed at the bottom of a water or sewage tank. When compressed air is supplied, the membrane bulges. The holes in the membrane open so that air enters the water. When the compressed air is switched off, the membrane lies down on the receiving plate under the static pressure of the water. The openings close. The unperforated part covers the compressed air connection. This prevents sludge and bacteria from entering the openings and the compressed air connection.
Aufgabe der Erfindung ist es, einen Membranbelüfter der eingangs genannten Art vorzuschlagen, dessen Aufbau vjreinfacht ist und bei dem ein zu weites Ausweiten der Membran verhindert ist.The object of the invention is to propose a membrane aerator of the type mentioned at the beginning, the structure of which is simplified and in which an excessive expansion of the membrane is prevented.
Erfindungsgemäß ist obige Aufgabe bei einem Membranbelüfter der eingangs genannten Art dadurch gelöst, daß die Membran mittels eines Klemmrings am Umfang des Aufnahmetellers gehalten ist und daß der Klemmring Haltestege aufweist, die sich über die Membran erstrecken und einen Anschlag für die Membran bilden.According to the invention, the above object is achieved in a membrane aerator of the type mentioned at the outset in that the membrane is held by means of a clamping ring on the circumference of the receiving plate and that the clamping ring has holding webs which extend over the membrane and form a stop for the membrane.
Der Klemmring erlaubt eine einfache und sichere Montage und Demontage der Membran an dem Aufnahmeteller.The clamping ring allows easy and safe assembly and disassembly of the membrane on the mounting plate.
Ab einer gewissen Ausweitung trifft die Membran auf die Haltestege. E»iese begrenzen die Ausweitung der Membran unter dem Einfluß der zugeführten Druckluft. Dadurch ist dieOnce the membrane has expanded to a certain extent, it hits the retaining bars. These limit the expansion of the membrane under the influence of the compressed air supplied. This means that the

In the middle of the receiving plate 1 there is a compressed air connection 3, which is formed, for example, by a threaded sleeve pressed into the receiving plate 1.
Es ist eine Membran '* vorgesehen, die eine Vielzahl von Löchern b aufweist. E>ie Löcher 5 sind trichterförmig gestaltet, wobei sie -,ich r.um Aufnahmeteller 1 hin erweitern (vgl. Figur 3a). In der Mitte der Membran 4 besteht eine ungelochte Teilfläche 6. Der Durchmesser der Membran 4 ist größer als der Durchmesser der planen Fläche des Aufnahmetellet^s 1. Er ist etwa gleich dem Durchmesser der planen Fläche zuzüglich der doppelten Höhe des Randes 2.A membrane '* is provided which has a large number of holes b. The holes 5 are funnel-shaped and widen out towards the receiving plate 1 (see Figure 3a). In the middle of the membrane 4 there is an unperforated partial area 6. The diameter of the membrane 4 is larger than the diameter of the flat surface of the receiving plate 1. It is approximately equal to the diameter of the flat surface plus twice the height of the edge 2.
Zur Festlegung der Membran 4 an dem Aufnahmetelier 1 ist ein Klemmring 7 mit einem Schlitz 8 vorgesehen. Beidseitig des Schlitzes 3 sind Winkel 9 befestigt, die sich mittels einer Schraube 10 und einer Mutter 11 verspannen lassen.A clamping ring 7 with a slot 8 is provided to secure the membrane 4 to the receiving part 1. Angles 9 are attached to both sides of the slot 3 and can be tightened using a screw 10 and a nut 11.
Der Klemmring 7 ist an seinem Rand mit einer Aufbiegung (vgl. Figur 4) versehen. Diese erleichtert die Montage und Demontage des Klenimrings 7.The clamping ring 7 has a bent edge (see Figure 4). This makes it easier to assemble and disassemble the clamping ring 7.

Die Montage des beschriebenen Membranbelüfters <u-folgt etwa folgendermaßen:The assembly of the described membrane aerator <u-follows approximately as follows:
Auf Jen Auf nahrnerel 1. er L wird di.e Membran '* zentriert iiurgelegt. ijanacli wii-v. der Klemmring 7 aut die Membran h aufgedrückt, radurch schwenkt der Rond der Membran &Iacgr; an den Rand 2 des A ir:iahmetellers 1. Die umlaufende ni.ibiegurig 12 des Kiemmr.i r "■ ■ erleichtert dessen Aufschieben.The membrane '* is placed centered on the outer surface 1. The clamping ring 7 is then pressed onto the membrane h , causing the edge of the membrane 'to swing to the edge 2 of the air diaphragm plate 1. The circumferential non-flexible ring 12 of the clamping ring '* makes it easier to slide it on.
SchiieJilich wird die Schraube I1J angezogen (vgl. Fi^ur 5). E)er Klemmring 7 spannt dabei, die Membran ^ fest gegen den Rand 2. Seine Haltestege Ii, 1·* erstrecken sich in einem kleinen Abstand über der Membran 0-. Die Teiif lache 6 liegt auf dem Druckluttanschiu.'ä 3 auf . Die Löchex- ' sind geschlossen.Finally, the screw I1J is tightened (see Figure 5). The clamping ring 7 clamps the membrane ^ firmly against the edge 2. Its retaining webs Ii, 1* extend a short distance above the membrane 0-. The partial surface 6 rests on the pressure-sealing connection 3. The holes x-' are closed.
Wird nun Druckl xi&idiagr; über den Druckiuf tanschi ufi 3 -i-mgeiei tez dann hebt die ungelochte Teiif Iac:,e b ab. jiese-s A .heben ist durch den ringförmigen Haltesteg 13 begrenzt. Die Luft gelangt nun zu den Löchern 5. Diese öffnen sich unter Ausweitung der MemDian &Iacgr;· in den Zoner, zwischen den Kaitestegen 13. Diese begrenzen das Aufweiten der Mer.'J.-ran '*. If pressure is now applied via the pressure switch 3, the unperforated part of the membrane lifts off. This lifting is limited by the ring-shaped retaining web 13. The air now reaches the holes 5. These open up into the zone between the webs 13, expanding the membrane. These limit the expansion of the membrane.
Wird die Druckluft abgeschaltet, dann geht die Membran 4
unter ihrer Eigenelastizität und dem statischen Druck des Wassers über ihr in ihre Ausgangsstellung zurück, in der die
Löcher 5 geschlossen sind und die ungelochte Teilfläche 6 den Druckluftanschluß 3 verdeckt. Schlamm und Wasser können
dadurch nicht in die Löcher 5 und den E>ruckluftanschluß 3
gelangen.If the compressed air is switched off, the membrane 4
under its own elasticity and the static pressure of the water above it, it returns to its initial position in which the holes 5 are closed and the unperforated part 6 covers the compressed air connection 3. This prevents mud and water from getting into the holes 5 and the compressed air connection 3.
