Description
Zum Behandeln eines Gutes mit Ultraschallschwingungen zu Zwecken verschiedenster Art sind u. a. keramische Piezoschwinger bekannt. Dies sind Schwinger, deren Schwingkörper aus Bariumtitanat oder einem anderen keramischen Stoff besteht, der durch eine bestimmte elektrische Behandlung pi.ezoelektrische Eigenschaften ähnlich einem Ouarzschwinger erhält.For treating goods with ultrasonic vibrations for a wide variety of purposes Art include ceramic piezo oscillator known. These are oscillators, their oscillating bodies consists of barium titanate or another ceramic material, which by a certain electrical treatment pi.ezoelectric properties similar to an Ouarzschwinger receives.
Die Erfindung befaßt sich mit der Ausbildung einer Beschallungseinrichtung für Gut beliebiger Art in einem Beschallungsbehälter, von dem ein Wandungsteil, insbesondere der Boden, aus einem Ultraschallschwinger aus keramischem Stoff, z. B. Bariumtitanat, besteht. Für nichtkeramische Piezoschwinger, also für Ultraschallschwinger mit einem Ouarzschwingkörper, ist es bereits bekannt, einen Beschallungsbehälter so auszubilden, daß ein Wandungsteil dieses Behälters, insbesondere der Boden, voll dem Ultraschallschwingkörper gebildet wird. Hierbei sind in der Regel besondere Maßnahmen erforderlich, um den Schwingkörper zuverlässig flüssiglceits- und gasdicht mit dem Behälter zu verbinden.The invention is concerned with the formation of a public address system for goods of any kind in a sonication tank, one wall part of which in particular the bottom, made of an ultrasonic transducer made of ceramic material, e.g. B. barium titanate. For non-ceramic piezo transducers, i.e. for ultrasonic transducers with an Ouarz oscillating body, it is already known to use a sound tank to be designed so that part of the wall of this container, in particular the bottom, is full the ultrasonic vibrating body is formed. These are usually special Measures are required to ensure that the vibrating body is reliably liquid-tight and gas-tight to connect to the container.
Erfindungsgemäß wird dies bei der genannten Beschallungseinrichtung dadurch gelöst, daß der Ultraschallschwinger mit demß Behälter verkittet ist, wobei vorzugsweise ein Kitt auf Zellulosebasis verwendet ist.According to the invention, this is the case with the above-mentioned sound system solved in that the ultrasonic transducer is cemented to the container, wherein preferably a cellulosic putty is used.
Besonders vorteilhaft ist es, die von den Elektrodenbelägen freie Randfläche des Schwingkörpers mit den übrigen Teilen des Behälters zu verkitten. An sich können jedoch auch andere Flächenteile des Schwingkörpers für die Verkittung herangezogen werden. In der Zeichnung ist als Ausführungsbeispiel eine Beschallungseinrichtung dargestellt, bei der gemäß der Erfindung Beschallungsbehälter i mit einem Hohlschwinger 2 verkittet ist. Der keramische Schwingkörper 2 dient als Boden des Behälters und ist auf seiner Innen- und Außenseite mit je einem Elektrodenbelag 3, q. versehen. Die Zuführungsleitungen der beiden Elektroden sind mit 5, 6 bezeichnet. Die Leitung 5 ist hierbei im Innern des Behälters i hochgeführt, wobei es zweckmäßig ist, diese Leitung samt der Elektrode 3 auf Erdpotential zu halten.It is particularly advantageous if the electrode deposits are free To cement the edge surface of the vibrating body with the remaining parts of the container. However, other parts of the surface of the oscillating body can also be used for cementing can be used. In the drawing, a public address system is shown as an exemplary embodiment shown, in the case of the sonication tank i with a hollow oscillator according to the invention 2 is cemented. The ceramic vibrating body 2 serves as the bottom of the container and is on its inside and outside each with an electrode coating 3, q. Mistake. The supply lines of the two electrodes are denoted by 5, 6. The administration 5 is here carried up inside the container i, it being useful to do this To keep the line together with the electrode 3 at ground potential.
Es ist auch ohne weiteres möglich, einen ebenen keramischen Schwingkörper mit dem Beschallungsgefäß gemäß der Erfindung zu verbinden. Hierbei sind mannigfache Möglichkeiten der Anordnung des Schwingkörpers in einem Wandungsteil des Gefäßes möglich.It is also easily possible to use a flat ceramic oscillating body to connect to the sonication vessel according to the invention. There are many Possibilities of arranging the vibrating body in a wall part of the vessel possible.
