Description
Zur Beschallung größerer Flüssigkeitsmengen kann man entweder die Flüssigkeit an den Schallstrahlern vorbeileiten oder die Schallstrahler so bewegen, daß die Schallstrahlen nacheinander den gesamten Flüssigkeitsraum bestreichen. For sonication of larger amounts of liquid you can either use the Guide liquid past the sound emitters or move the sound emitters in such a way that that the sound beams sweep the entire liquid space one after the other.
Erfindungsgemäß läßt sich eine Beschallung großer Flüssigkeitsmengen auf besonders einfache und zweckmäßige Art und Weise dadurch erzielen, daß die Schallerzeuger, vorzugsweise in Analogie zum Segnerschen Wasserrad, so beweglich gelagert sind, daß der Schallstrahlungsdruck als Bewegungskraft dient. Bei Luftschallerzeugern mit Resonatoren ist zwar bekannt, daß man die Gleichrichterwirkung der Luftströmung in der Resonatorenmündung durch Rotation in der Weise eines Segnerschen Wasserrades nachweisen kann. Diese Anordnung ist jedoch nur zu Laborzwecken verwendet worden; zum Beschallen größerer Räume mit Hilfe bewegter Schallstrahler hat man dagegen bisher immer einen besonderen Antrieb vorgesehen. According to the invention, large amounts of liquid can be sonicated achieve in a particularly simple and expedient manner that the sound generator, preferably in analogy to Segner's water wheel, so movably mounted, that the sound radiation pressure serves as a motive force. With airborne sound generators With resonators it is known that the rectifying effect of the air flow can be achieved in the mouth of the resonator by rotation in the manner of a Segner water wheel can prove. However, this arrangement has only been used for laboratory purposes; on the other hand, one has to use moving sound emitters to fill larger rooms with sound up to now a special drive has always been provided.
In der Zeichnung ist die Erfindung beispielsweise veranschaulicht. In einem mit Flüssigkeit gefüllten Behälter I sind am unteren Ende einer vertikalen, im Deckel 2 gelagerten Welle 3 vier magnetostriktive Schallstrahler 5, go0 gegeneinander versetzt, angeordnet. Um einen größeren Wirkraum während der Umdrehung zu bestreichen, sind die Strahler so geneigt, daß ihre Hauptstrahlrichtung mit der Radialebene einen Winkel a einschließt. Die rückseitige Strahlfläche der Schwinger ist abgeschirmt, so daß sämtliche Schwinger mit ihrem Strahlungsdruck in gleichem Sinn auf die Welle einwirken und eine Drehbewegung in Analogie zum Segnerschen Wasserrad hervorrufen. Auf diese Weise wird der gesamte Flüssigkeitsraum gleichmäßig beschallt. Durch die Bewegung der flügelradartig wirkenden Strahler wird die Flüssigkeit im Behälter umgewälzt. The invention is illustrated by way of example in the drawing. In a container I filled with liquid are at the lower end of a vertical, in the cover 2 mounted shaft 3 four magnetostrictive sound emitters 5, go0 against each other staggered, arranged. To cover a larger active space during the rotation, the emitters are inclined so that their main beam direction is one with the radial plane Angle a includes. The rear beam surface of the transducer is shielded, so that all transducers with their radiation pressure in the same sense on the shaft act and cause a rotary movement in analogy to Segner's water wheel. In this way, the entire liquid space is sonicated evenly. Through the Movement of the impeller-like emitters is the liquid in the container circulated.
Die Magnetostriktionsschwinger können, wenn eine Berührung mit der zu beschallenden Flüssigkeit unerwünscht ist, eingekapselt sein. Natürlich können auch andere, z. B. piezoelektrische Schallerzeuger mit gerichteter Schallstrahlung verwendet werden. Ferner ist es vorteilhaft, zum Beschallen größerer Räume mehrere Schallstrahler an gemeinsamer Welle axial gegeneinander versetzt anzuordnen. The magnetostrictive transducer can when a contact with the liquid to be sonicated is undesirable, be encapsulated. Of course you can also others, e.g. B. piezoelectric sound generator with directed sound radiation be used. It is also advantageous to use several of them to fill larger rooms with sound To arrange sound emitters axially offset from one another on a common shaft.
Schließlich kann die Erfindung auch zum Beschallen von Luft- oder Gas räume sinngemäß verwendet werden, jedoch nicht durch Gleichrichterwirkung von Resonatoren, sondern durch Gasschwinggeneratoren, die mit einem Luftstrom betrieben werden, wie Sirenen oder Pfeifen, und bei denen die Rückstoßwirkung des austretenden Gasstromes zum Bewegen von Schallstrahlern für industrielle Zwecke ausreicht. Finally, the invention can also be used for the irradiation of air or Gas spaces can be used in the same way, but not through the rectifying effect of Resonators, but rather by gas oscillating generators that are operated with a stream of air be like sirens or whistles, and in which the recoil effect of the escaping Sufficient gas flow for moving sound emitters for industrial purposes.
