Definitions

  • the invention relates to an ultrasonic cleaning system for hollow bodies, which has a container with a transmission medium, an ultrasonic generator and a vibrating plate, the vibrating plate being excitable by means of the ultrasonic generator. Furthermore, the invention relates to a method for cleaning hollow bodies by means of an ultrasound cleaning system, the ultrasound cleaning system having a container with a transmission medium, an ultrasound generator and an oscillating plate, and the oscillating plate being excited by means of the ultrasound generator with a predefined oscillation frequency.
  • Ultrasound is very often used for cleaning objects and products, especially for cleaning difficult to access surfaces and complex shaped objects. Furthermore, ultrasonic cleaning can also be used if a very high degree of purity is to be produced or if cleaning with other methods is associated with health risks for the personnel.
  • Typical examples of objects that are often cleaned using ultrasound are parts of precision engineering and precision engineering, medical instruments, optical lenses, glass vessels, dentures, jewelry, etc. The cleaning is carried out by immersing the object to be cleaned in an ultrasound-excited liquid bath or by fixing it in this.
  • problems always arise when hollow bodies are to be cleaned.
  • the hollow bodies are cleaned with sonotrodes.
  • the needle-shaped sonotrodes are inserted into the hollow body and vibrated.
  • DE 199 09 197 discloses such an ultrasonic cleaning system, in which the shaft-shaped ultrasonic sonotrode device can be inserted into the hollow structure of the workpiece and can also be moved back and forth relative to the workpiece.
  • the US 5,985,038 and EP 0 292 779 disclose another system.
  • the hollow bodies for example medical instruments with cannulas (US Pat. No. 5,985,038) and components for ink printers (EP 0 292 779), are flushed out by a cleaning medium.
  • the flushing medium and / or the component is subjected to ultrasound, so that in addition to the flushing effect, there is also an ultrasound effect.
  • both systems have the disadvantage that the hollow body can only be cleaned on the inside and not at the same time also on the outside.
  • the hollow body must either be subsequently introduced into an ultrasonic bath with, for example, a plate-shaped surface oscillator.
  • Another possibility is that the outside of the hollow body is cleaned by a further vibrating body, for example an additional surface vibrator. Simultaneous cleaning of the outside and inside is not possible with the known devices and methods.
  • the object of the present invention is therefore to provide an ultrasonic cleaning system for hollow bodies, with which the outside and the inside of the hollow body can be cleaned at the same time. Another object is that a method for cleaning hollow bodies is made available, with which the outside and inside of a hollow body is effectively cleaned at the same time.
  • the ultrasonic cleaning system for hollow bodies has a container with a transmission medium, an ultrasonic generator and a vibrating plate.
  • the oscillating plate can be excited by means of the ultrasound generator, wherein at least one transmission element connected to the oscillating plate can be set in vibration by the excitation of the oscillating plate.
  • the transmission element is rod-shaped or needle-shaped, which is excited to oscillate by the oscillation of the oscillating plate.
  • the transmission element generates cavitation bubbles in the interior of the hollow body, which clean the inside of the hollow body.
  • the outside of the hollow body is cleaned by the vibrations of the membrane-like vibrating plate that occur in particular at the edge.
  • the transmission element is variable in shape and length, so that it can be selected depending on the items to be cleaned and the resonance frequencies. If, for example, a very long hollow body is to be cleaned, a correspondingly long transmission element can be used.
  • the transmission element is preferably releasably connected to the oscillating plate, in particular screwable. This design enables the transfer element to be changed quickly and easily, for example depending on the items to be cleaned.
  • the transmission element can additionally have nozzles for the escape of transmission medium, water or cleaning agents, as a result of which the cleaning of the inside of the hollow body is intensified. This is particularly advantageous when cleaning the inside of the hollow body is particularly critical, for example when cleaning cannulas or other hollow bodies used in medicine.
  • the inventive method for cleaning hollow bodies is carried out by means of an ultrasonic cleaning system.
  • the ultrasound Cleaning system has a container with a transmission medium, an ultrasound generator and an oscillating plate, the oscillating plate being excited with a predefined oscillation frequency.
  • a hollow body is slipped onto the transmission element connected to the oscillating plate to form a single oscillating system, and the transmission element is set into vibration by the excitation of the oscillating plate. In this way, both the outside and the inside of the hollow body are cleaned at the same time.
  • the power intensity between the vibrating plate and the transmission element and thus the intensity of the cleaning of the outside and inside can be changed. This is achieved by shifting the oscillation frequency. In this way, the vibrating plate vibrates with a different intensity than the transmission element, whereby, for example, the inside can be cleaned more than the outside or vice versa.
  • a hollow body that is preferably fixed relative to the container is thus cleaned both on the outside and on the inside.

  • the transmission element 9 can be equipped with at least one, preferably a plurality of nozzles (not shown). Liquid, in particular transmission medium 3 or a cleaning solution, can be sprayed onto the inside of the hollow body 12 via these nozzles, thereby increasing the cleaning effect.
