Description
Die Erfindung betrifft eine Vorrichtung zur Schalldämpfung in Leitungen, insbesondere für Lüftungsanlagen ο. dgl., für Räume, in die ständig öder teilweise Luft eingeführt wird.The invention relates to a device for soundproofing in lines, in particular for ventilation systems ο. Like., For rooms in which air is constantly or partially introduced will.
Bei solchen Anlagen ist nun das Geräusch, der Luftbewegungsmotoren bzw. der Luftbeweger sowie unter Umständen auch das Geräusch, der strömenden Luft störend, auch gelangen durch die Leitung störende Geräusche von außerhalb nach innen.In such systems, the noise is now the air movement motors or the air mover as well as, under certain circumstances, the noise of the flowing air, too Disturbing noises can get through the line from outside to inside.
Diese Nachteile werden erfindungsgemäß durch den Einbau von besonderen Schalldämpfern behoben, und zwar dadurch, daß in die Zuführungs- bzw. Abführungsleitung in Richtung der Luftströmung Gruppen von Platten eingesetzt sind, die die SchaÜschwingungen ausgleichen. Dabei sollen diese Platten vorzugsweise aus akustisch stumpfem Baustoff bestehen, d.h. aus einem Baustoff, der an sich schon die Schallwellen dämpft.According to the invention, these disadvantages are caused by the installation of special silencers fixed, namely that in the supply or discharge line in the direction of the air flow groups of Plates are used that compensate for the SchaÜschwenken. In doing so, these panels should preferably consist of acoustically dull building material, i.e. a building material that in itself already dampens the sound waves.
Diese in der Luftleitung in Gruppen zusammengefügten Platten liegen vorzugsweise parallel zueinander in der Strömungsrichtung und können dabei ebenflächig sein.These plates, which are joined together in groups in the air duct, are preferably located parallel to each other in the direction of flow and can be flat.
Die Gruppen können aber auch aus einander kreuzenden Platten bestehen. Ferner können die Platten hintereinanderliegender Gruppen im Winkel zueinander geneigt sein.The groups can also consist of intersecting plates. Further the plates of consecutive groups can be inclined at an angle to one another.
Es können außerdem mehrere solcher Plattcngruppen hintereinandergeschaltet werden, wobei der Abstand zwischen zwei aufeinanderfolgenden Gruppen je nach den besonderen Verhältnissen, z. B. Luftgeschwindigkeit usw., verschieden groß gewählt wird. Auch kann dieser Abstand regelbar gemacht sein, so daß ein nachträgliches Einstellen möglich ist.In addition, several such plate groups can be connected in series, being the distance between two consecutive groups depending on the particular Conditions, e.g. B. air speed, etc., is chosen to be of different sizes. This distance can also be made adjustable so that subsequent setting is possible.
In der Zeichnung ist die Erfindung in verschiedenen Ausführungsbeispielen veranschaulicht. The invention is illustrated in various exemplary embodiments in the drawing.
Fig. ι ist eine räumliche Darstellung und zeigt zwei hintereinanderliegende Plattengruppen. Fig. Ι is a three-dimensional representation and shows two plate groups one behind the other.
Fig. 2 zeigt gleichfalls in räumlicher Darstellung im Zusammenhang mit Fig. 1 eine andere Ausführung mit einer Gruppe sich kreuzender Platten.FIG. 2 likewise shows a three-dimensional representation in connection with FIG. 1 another version with a group of intersecting plates.
Fig. 3 ist eine Vorderansicht zu Fig. 1.FIG. 3 is a front view of FIG. 1.
Fig. 4 zeigt in Stirnansicht eine weitere Ausführung, bei welcher die Platten im Winkel zueinander geneigt sind.Fig. 4 shows a front view of a further embodiment in which the plates at an angle are inclined to each other.
Fig. s zeigt in teilweiser Darstellung entsprechend Fig. ι eine längere Anlage.Fig. S shows in a partial representation corresponding to Fig. Ι a longer system.
Es ist α die Wandung der Luftführung, die bei dem dargestellten Ausführungsbeispiel vieleckigen (quadratischen) Querschnitt aufweist.It is α the wall of the air duct, which in the illustrated embodiment has a polygonal (square) cross section.
In die Luftführung sind jeweils eine Gruppe bildende Platten b aus schalldämpfendem Baustoff in Richtung der Luftströmung, die durch Pfeile c angedeutet ist, eingesetzt. Diese Platten können nun abwechselnd eine verschiedene Richtung haben. So kann, wie ausIn each case, a group-forming plates b made of sound-absorbing building material are inserted into the air duct in the direction of the air flow, which is indicated by arrows c. These plates can now alternately have a different direction. So can how out

Pig. ι, 3 und 5 ersichtlich ist, die erste Gruppe B1 senkrecht verlaufen, die zweite Gruppe B2 waagerecht.Pig. ι, 3 and 5 can be seen, the first group B 1 run vertically, the second group B 2 horizontally.
Ferner kann, wie bei der Ausführung nach Fig. 2 ersichtlich ist, die Gruppe B3 aus zwei sich unter go° kreuzenden Platten bestehen oder auch (s. Fig. 4) aus zwei unter einem beliebigen Winkel sich kreuzenden, so daß die Platten dann zwischen sich, kleine Luftwege bilden, die z. B. vieleckige, d.h. rechtwinkelige oder quadratische Querschnitte haben können.Furthermore, as can be seen in the embodiment according to FIG. 2, the group B 3 can consist of two plates crossing one another under go ° or also (see FIG. 4) of two crossing one another at any angle, so that the plates then between them, form small airways that z. B. polygonal, ie rectangular or square cross-sections.
Bei der Ausführung nach Fig. 5 ist eine längere Anlage dargestellt, bei der mehrere Plattengruppen hintereinander angeordnet sind. Zweckmäßig werden dabei die Abstände zwischen den einzelnen Gruppen verschieden groß bemessen.In the embodiment of FIG. 5, a longer system is shown in which several Plate groups are arranged one behind the other. The distances are useful here different sizes between the individual groups.
Als Baustoff für die Luftführungsplatten b und die äußeren Begrenzungswände α können z. B. Korkplatten oder ähnliche schalldämpfende Baustoffe verwendet werden.As a building material for the air guide plates b and the outer boundary walls α can, for. B. cork panels or similar sound-absorbing building materials can be used.
