Description

  • Die Erfindung betrifft ein Ultraschall-Reinigungssystem für Hohlkörper, welches einen Behälter mit einem Übertragungsmedium, einen Ultraschallgenerator und eine Schwingplatte aufweist, wobei die Schwingplatte mittels des Ultraschallgenerators erregbar ist. The invention relates to an ultrasonic cleaning system for hollow bodies, comprising a container having a transmission medium, an ultrasonic generator and an oscillating plate, said oscillating plate is excitable by means of the ultrasonic generator.
  • Ultraschall wird sehr häufig zur Reinigung von Gegenständen und Produkten, insbesondere zur Reinigung von schwer zugänglichen Oberflächen und kompliziert geformten Gegenständen eingesetzt. Ultrasound is frequently used for cleaning articles and products, in particular for cleaning hard to reach surfaces and complex shaped objects. Ferner kann die Ultraschallreinigung auch verwendet werden, wenn ein sehr hoher Reinheitsgrad erzeugt werden soll oder wenn eine Reinigung mit anderen Methoden mit Gesundheitsrisiken für das Personal verbunden ist. Furthermore, the ultrasonic cleaning can also be used when a very high degree of purity to be produced or when cleaning with other methods is associated with health risks for staff. Als typische Beispiele von Gegenständen, welche oft mittels Ultraschall gereinigt werden, seien Teile der Feinmechanik und der Feinwerktechnik, medizinische Instrumente, optische Linsen, Glasgefässe, Zahnprothesen, Schmuck etc. angeführt. As typical examples of items that are often ultrasonically cleaned, parts of precision engineering and precision engineering, medical instruments, optical lenses, glass containers, dentures, jewelry, etc. are cited. Die Reinigung erfolgt dadurch, dass der zu reinigende Gegenstand in ein ultraschallerregtes Flüssigkeitsbad getaucht wird bzw. in diesem fixiert wird. The cleaning takes place in that the object to be cleaned is immersed in an ultrasonically energized liquid and is fixed in this. Probleme ergeben sich jedoch immer dann, wenn Hohlkörper gereinigt werden sollen. Problems arise, however, whenever the hollow body to be cleaned.
  • Im Stand der Technik sind im wesentlichen zwei Methoden zur Reinigung von Hohlkörpern mittels Ultraschall bekannt. In the prior art, two methods for the purification of hollow bodies by means of ultrasound are known essentially. Bei dem einen System werden die Hohlkörper mit Sonotroden gereinigt. In one system, the hollow bodies are cleaned with horns. Hierfür werden die nadelförmigen Sonotroden in den Hohlkörper eingeführt und in Schwingung versetzt. For this, the needle-shaped horns are introduced into the hollow body and vibrated. Die The DE 199 09 197 DE 199 09 197 offenbart eine derartige Ultraschall-Reinigungsanlage, wobei dort die schaftförmige Ultraschall-Sonotrodeneinrichtung in die Hohlstruktur des Werkstückes einbringbar und zusätzlich relativ zum Wertstück hin- und herbewegbar ist. discloses such an ultrasonic cleaning system, there being introduced and in addition relatively reciprocating the shaft-shaped ultrasonic Sonotrodeneinrichtung in the hollow structure of the workpiece to the value of piece and forth. DE 25 46 818 DE 25 46 818 zeigt eine Ultraschallreinigungsvorrichtung gemäß dem Oberbegriff von Anspruch 1, die zum Reinigen der Innenseite eines Rohres geeignet ist. shows an ultrasonic cleaning apparatus according to the preamble of claim 1 which is suitable for cleaning the inside of a tube. Dazu wird eine Schwingersäule in das zu reinigende Rohr eingeschoben und dort anhaftende Verunreinigungen oder sonstige Beläge entfernt. For this purpose, an oscillator column is inserted into the pipe to be cleaned and there adhering impurities or other coverings removed.
  • Die The US 5,985,038 US 5,985,038 und and EP 0 292 779 EP 0292779 offenbaren ein weiteres System. disclose another system. Hierbei werden die Hohlkörper, beispielsweise medizinische Instrumente mit Kanülen ( Here, the hollow body, such as medical instruments (with needles US 5,985,038 US 5,985,038 ) und Bauteile für Tintendrucker ( ) And components of the ink printer ( EP 0 292 779 EP 0292779 ), von einem Reinigungsmedium durchspült. ), Flushed with a cleaning medium. Zusätzlich wird das Spülmedium und/oder das Bauteil ultraschallbeaufschlagt, so dass zusätzlich zur durchspülenden Wirkung noch eine Ultraschallwirkung hinzukommt. In addition, the flushing medium and / or the component is ultraschallbeaufschlagt so that additionally is added to an ultrasonic action by flushing effect. In der In the US 2004/0251773 US 2004/0251773 ist dabei bei gleichmässigem Umwälzen des Reinigungsmediums eine Zuführung des Mediums über eine bodenseitig angeordnete Einlassöffnung für das Reinigungsmedium vorgesehen. is provided a supply of the medium through a bottom side arranged inlet opening for the cleaning medium with uniform circulation of the cleaning medium.
  • Den Systemen haftet jedoch der Nachteil an, dass der Hohlkörper nur auf der Innenseite und nicht zugleich auch auf der Aussenseite gereinigt werden kann. However, the systems have the disadvantage that the hollow body can be cleaned on the inside and not also on the outside. Zur Reinigung der Aussenseite muss der Hohlkörper entweder anschliessend in ein Ultraschallbad mit beispielsweise einem plattenförmigen Flächenschwinger eingebracht werden. To clean the outside of the hollow body must then either be incorporated in an ultrasonic bath with such as a sheet-like base oscillator. Eine weitere Möglichkeit ist, dass die Reinigung der Aussenseite des Hohlkörpers durch einen weiteren Schwingkörper, beispielsweise einen zusätzlichen Flächenschwinger, erfolgt. Another possibility is that the cleaning of the outside of the hollow body, is carried out by a further vibrating body, for example, an additional surface vibrator. Eine gleichzeitige Reinigung von Aussenund Innenseite ist jedoch mit den bekannten Vorrichtungen und Verfahren nicht möglich. However, a simultaneous cleaning of outside and inside is not possible with the known devices and methods.
  • Aufgabe der vorliegenden Erfindung ist daher, ein Ultraschall-Reinigungssystem für Hohlkörper zur Verfügung zu stellen, mit dem zugleich die Aussenseite und die Innenseite des Hohlkörpers gereinigt werden kann. It is therefore to provide an ultrasonic cleaning system for hollow bodies available to the outside and the inside of the hollow body can be cleaned at the same time with the object of the present invention.
  • Diese Aufgabe wird gelöst durch ein Ultraschall-Reinigungssystem gemäss Anspruch 1. This object is achieved by an ultrasonic cleaning system according to Claim. 1
  • Das erfindungsgemässe Ultraschall-Reinigungssystem für Hohlkörper weist einen Behälter mit einem Übertragungsmedium, einen Ultraschallgenerator und eine Schwingplatte auf. The inventive ultrasonic cleaning system for hollow body has a container with a transmission medium, an ultrasonic generator and a vibration plate. Die Schwingplatte ist mittels des Ultraschallgenerators erregbar, wobei zumindest ein mit der Schwingplatte verbundenes Übertragungselement durch die Erregung der Schwingplatte in Schwingung versetzbar ist. The vibrating plate is excitable by means of the ultrasonic generator, wherein at least one end connected to the oscillating plate transfer member by the excitation of the vibrating plate can be set into oscillation. Das Übertragungselement ist dabei mit der Schwingplatte lösbar verbunden, insbesondere aufschraubbar. The transmission member is detachably connected to the oscillating plate, in particular screwed. Durch diese Gestaltung ist ein Wechseln des Übertragungselementes, beispielsweise in Abhängigkeit vom Reinigungsgut, schnell und problemlos möglich. This design is a change of the transmission element, for example, depending on the items to be cleaned quickly and without problems.
  • Vorzugsweise ist vorgesehen, dass das Übertragungselement stab- oder nadelförmig gestaltet ist, wobei dieses durch die Schwingung der Schwingplatte zum Mitschwingen erregt wird. It is preferably provided that the transmission element is rod-shaped or needle-shaped, this is excited by the vibration of the vibrating plate to vibrate. Dadurch erzeugt das Übertragungselement im Innenbereich des Hohlkörpers Kavitationsblasen, welche die Innenseite des Hohlkörpers reinigen. Characterized the transfer element produced in the interior of the hollow body cavitation bubbles, which clean the inside of the hollow body. Zugleich wird die Aussenseite des Hohlkörpers durch die insbesondere randseitig auftretenden Schwingungen der membranartigen Schwingplatte gereinigt. At the same time the outside of the hollow body is cleaned by the particular edges occurring vibrations of the membrane-like vibrating plate.
  • Auf diese Art und Weise ergibt sich der grosse Vorteil, dass mittels des erfindungsgemässen Ultraschall-Reinigungssystems Hohlkörper sowohl auf der Innenseite als auch auf der Aussenseite durch ein einziges Schwingsystem effektiv gereinigt werden können. In this manner, the great advantage that the hollow body can be cleaned effectively both on the inside and on the outside by a single oscillating system by means of the inventive ultrasonic cleaning system. Die Reinigung des Hohlkörpers geht mittels des erfindungsgemässen Ultraschall-Reinigungssystems sowohl schnell als auch gründlich vonstatten. The cleaning of the hollow body goes by means of the inventive ultrasonic cleaning system both quickly and thoroughly vonstatten. Das Übertragungselement ist variabel in Form und Länge, so dass es in Abhängigkeit vom Reinigungsgut und den Resonanzfrequenzen gewählt werden kann. The transmission element is variable in shape and length, so that it can be selected depending on the items to be cleaned and the resonant frequencies. Soll beispielsweise ein sehr langer Hohlkörper gereinigt werden, so kann ein dementsprechend langes Übertragungselement eingesetzt werden. For example, if a very long hollow body to be cleaned, so a correspondingly long transfer element may be used.
  • Ein weiteres bevorzugtes Ausführungsbeispiel der Erfindung sieht vor, dass das Übertragungselement zusätzlich Düsen zum Austritt von Übertragungsmedium, Wasser oder Reinigungsmitteln aufweisen kann, wodurch die Reinigung der Innenseite des Hohlkörpers verstärkt wird. A further preferred embodiment of the invention provides that the transfer element may comprise nozzles for discharge of transmission medium, water or detergent addition, thereby cleaning the inside of the hollow body is increased. Dieses ist insbesondere dann vorteilhaft, wenn die Reinigung der Innenseite des Hohlkörpers besonders kritisch ist, beispielsweise bei der Reinigung von Kanülen oder anderen in der Medizin eingesetzten Hohlkörpern. This is particularly advantageous if the cleaning of the inside of the hollow body is particularly critical, for example in the purification of cannulas or other hollow articles used in medicine.
  • Nachstehend wird die Erfindung anhand der Zeichnung näher erläutert und beschrieben. The invention is further illustrated by the drawings and described. Es zeigt: It shows:

Das Übertragungselement 9 ist vorzugsweise lösbar mit der Schwingplatte 5 verbunden. The transmission element 9 is preferably detachably connected to the vibrating plate. 5 So kann es beispielsweise mit seiner Basis 10 in eine Bohrung 8 der Schwingplatte 5 einschraubbar sein. It may be screwed into a bore 8 of the vibrating plate 5, for example, with its base 10 degrees. Das Übertragungselement 9 ist vorzugsweise nadelartig oder stabartig gestaltet. The transmission element 9 is designed preferably needle-like or rod-like. Es kann hohl oder massiv ausgebildet sein und hat vorzugsweise einen runden Querschnitt. It can be hollow or solid, and preferably has a round cross-section.
  • Darüber hinaus kann das Übertragungselement 9 mit zumindest einer, vorzugsweise mehreren Düsen ausgestattet sein (nicht gezeigt). Moreover, the transmission member 9 may be equipped with at least one, preferably a plurality of nozzles (not shown). Über diese Düsen kann Flüssigkeit, insbesondere Übertragungsmedium 3 oder eine Reinigungslösung, auf die Innenseite des Hohlkörpers 12 gesprüht werden, wodurch die Reinigungswirkung verstärkt wird. This nozzle can be liquid, in particular transmission medium 3 or a cleaning solution is sprayed onto the inside of the hollow body 12, whereby the cleaning effect is enhanced. Vorzugsweise ist eine Vielzahl von Übertragungselementen 9 auf der Schwingplatte 5 angeordnet. Preferably, a plurality of transmission elements 9 on the vibrating plate 5 is arranged. Auf diese Art und Weise können viele Hohlkörper 12 zugleich gereinigt werden. In this way many hollow body 12 can be cleaned at the same time. Die Schwingplatte 5 bildet vorzugsweise den Boden des Behälters 2 und ist gegen Leckagen mittels Dichtungen 13 abgesichert. The vibrating plate 5 preferably constitutes the bottom of the container 2 and is protected against leakage by means of seals. 13 Die membranartig gestaltete Schwingplatte 5 ist vorzugsweise über Verbindungsmittel 14, beispielsweise Schrauben, mit dem Behälter 2 lösbar verbunden. The membrane-like shaped vibrating plate 5 is preferably detachably connected via connecting means 14 such as bolts with the container. 2 Der Behälter 2 weist vorzugsweise einen Zulauf 15 und einen Ablauf 16 auf. The container 2 preferably has an inlet 15 and an outlet sixteenth Dabei ist bevorzugt, dass der Zulauf 15 sich im bodennahen Bereich des Behälters 2 befindet, dh in der Nähe der Schwingplatte 5. Der Ablauf 16 befindet sich dagegen im oberen Bereich, dh in der Nähe des Randes 19 des Behälters 2. Auf diese Art und Weise werden durch den Reinigungsvorgang abgetrennte Trümmer, Debris oder sonstige Verschmutzungen über den oben liegenden Ablauf 16 entfernt. It is preferred that the inlet 15 is located in the region near the bottom of the container 2, ie in the vicinity of the vibrating plate 5. The drain 16 is located on the other hand in the upper region, ie, in the vicinity of the edge 19 of the container 2. In this way manner are removed by the cleaning operation separated debris, debris or other contaminants via the overhead flow sixteenth Vorzugsweise ist ein Überlauf 17 vorgesehen, so dass das Ultraschall-Reinigungssystem mit frischem Übertragungsmedium 3 durchspült werden kann, wie durch den Pfeil 18 angedeutet ist. Preferably, an overflow 17 is provided so that the ultrasonic cleaning system can be flushed with fresh transfer medium 3, as indicated by the arrow 18th
  • Ein Hohlkörper 12 kann auf das Übertragungselement 9 übergestülpt bzw. aufgesetzt werden. A hollow body 12 can be imposed on the transmission element 9 and mounted. Anschliessend wird die Schwingplatte 5 mittels des Ultraschallgenerators 4 in Schwingung versetzt, wodurch das auf der Schwingplatte 5 befestigte Übertragungselement 9 in Schwingung versetzt wird. Subsequently, the vibrating plate 5 is displaced by means of the ultrasonic generator 4 to vibrate, whereby the vibrating plate 5 fixed on the transfer member is vibrated. 9 Durch die Schwingungen des Übertragungselementes 9 werden Kavitationsblasen im Innenbereich des Hohlkörpers 12 erzeugt, welche die Innenseite des Hohlkörpers 12 reinigen. By the vibrations of the transmission element 9 cavitation bubbles are generated in the interior of the hollow body 12, which clean the inside of the hollow body 12th Zugleich werden durch die Schwingungen der Schwingplatte 5, insbesondere im radial äusseren Bereich Kavitationsblasen im Übertragungsmedium 3 erzeugt, welche die Aussenseite des Hohlkörpers 12 reinigen. At the same time are represented by the vibrations of the vibrating plate 5, in particular in the radially outer region of cavitation bubbles in the transmission medium 3 produced which clean the outside of the hollow body 12th Durch Verändern der durch den Ultraschallgenerator 4 erzeugten Schwingfrequenz kann die Leistungsintensität zwischen Schwingplatte 5 und dem Übertragungselement 9 verschoben werden, wodurch sich eine Verschiebung der Intensität der Reinigung der Aussenseite gegenüber der Innenseite des Hohlkörpers 12 ergibt. By varying the oscillation frequency generated by the ultrasonic generator 4, the power intensity between the vibrating plate 5 and the transfer member 9 can be moved, whereby a shift of the intensity of the cleaning of the outer side opposite the inner side of the hollow body 12 provides.
