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, wherein the vibrating plate is excitable by means of the ultrasonic generator.
  • Ultrasound is very often used for cleaning articles and products, in particular for cleaning hard-to-reach surfaces and intricately shaped objects. Furthermore, ultrasonic cleaning can also be used if a very high degree of purity is to be generated or if cleaning with other methods entails health risks for the staff.
  • objects which are often cleaned by means of ultrasound, parts of precision engineering and precision engineering, medical instruments, optical lenses, glass vessels, dentures, jewelry, etc. are listed. The cleaning takes place in that the object to be cleaned is immersed in an ultrasound-excited liquid bath or is fixed in this. However, problems always arise when hollow bodies are to be cleaned.
  • the hollow bodies are cleaned with sonotrodes.
  • the needle-shaped sonotrodes are introduced into the hollow body and set in vibration.
  • the DE 199 09 197 discloses such an ultrasonic cleaning system, where there the shaft-shaped ultrasonic sonotrode device in the hollow structure of the workpiece can be introduced and additionally moved back and forth relative to the value piece.
  • DE 25 46 818 shows an ultrasonic cleaning device according to the preamble of claim 1, which is suitable for cleaning the inside of a pipe. For this purpose, a vibrating column is inserted into the pipe to be cleaned and there removes adhering impurities or other deposits.
  • the US 5,985,038 and EP 0 292 779 reveal another system.
  • the hollow bodies for example medical instruments with cannulas ( US 5,985,038 ) and components for ink printers ( EP 0 292 779 ), rinsed by a cleaning medium.
  • the flushing medium and / or the component is subjected to ultrasound, so that in addition to the flushing effect, an ultrasonic effect is added.
  • the US 2004/0251773 is thereby provided with uniform circulation of the cleaning medium, a supply of the medium via a bottom side arranged inlet opening for the cleaning medium.
  • the systems however, has the disadvantage that the hollow body can only be cleaned on the inside and not on the outside at the same time.
  • To clean the outside of 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 cleaning of the outside of the hollow body by a further oscillating body, for example, an additional surface oscillator takes place.
  • a simultaneous cleaning of the outside and inside is not possible with the known devices and methods.
  • Object of the present invention is therefore to provide an ultrasonic cleaning system for hollow body, with the same time the outside and the inside of the hollow body can be cleaned.
  • the inventive ultrasonic cleaning system for hollow bodies has a container with a transmission medium, an ultrasonic generator and a vibrating plate.
  • the vibration plate can be excited by means of the ultrasonic generator, wherein at least one transmission element connected to the vibration plate can be set into oscillation by the excitation of the vibration plate.
  • the Transmission element is detachably connected to the swing plate, in particular screwed.
  • the transmission element is designed rod-shaped or needle-shaped, which is excited by the vibration of the vibrating plate to resonate.
  • the transmission element generates cavitation bubbles in the interior region of the hollow body, which clean the inside of the hollow body.
  • the outside of the hollow body is cleaned by the oscillations of the membrane-like vibrating plate which occur in particular at the edge.
  • the transmission element is variable in shape and length, so that it can be selected depending on the cleaning material and the resonance frequencies. For example, if a very long hollow body to be cleaned, so a correspondingly long transmission element can be used.
  • a further preferred embodiment of the invention provides that the transmission element may additionally comprise nozzles for the outlet of the transmission medium, water or cleaning agents, whereby the cleaning of the inside of the hollow body is reinforced. This is particularly advantageous if the cleaning of the inside of the hollow body is particularly critical, for example, in the cleaning of needles or other hollow bodies used in medicine.
  • Fig. 1 shows a section through an inventive ultrasonic cleaning system 1 for at least one hollow body 12, which is shown here in dashed lines. It consists of a container 2 in which a transmission medium 3 is contained.
  • the transfer medium 3 may be any known transfer medium used in the ultrasonic cleaning technique, for example, a cleaning solution, an organic solvent or water.
  • the ultrasonic cleaning system 1 has an ultrasonic generator 4 which is mounted on the non-sound radiating surface 6 of a vibrating plate 5.
  • the transmission element 9 is preferably made of a base 10 and a shaft 11, on which the hollow body 12 to be cleaned is slipped over or placed.
  • the transmission element 9 is preferably detachably connected to the oscillating plate 5. So it can be screwed, for example, with its base 10 in a bore 8 of the vibrating plate 5.
  • the transmission element 9 is preferably designed needle-like or rod-like. It may be hollow or solid and preferably has a round cross-section.
  • the transmission element 9 may be equipped with at least one, preferably a plurality of nozzles (not shown). Via these nozzles, liquid, in particular transfer medium 3 or a cleaning solution, can be sprayed onto the inside of the hollow body 12, whereby the cleaning effect is enhanced.
  • a plurality of transmission elements 9 is arranged on the oscillating plate 5. In this way, many hollow body 12 can be cleaned at the same time.
  • the oscillating plate 5 preferably forms the bottom of the container 2 and is secured against leaks by means of seals 13.
  • the membrane-like shaped vibrating plate 5 is preferably detachably connected to the container 2 via connecting means 14, for example screws.
  • the container 2 preferably has an inlet 15 and a drain 16.
  • the inlet 15 is located near the bottom of the container 2, ie in the vicinity of the vibrating plate 5.
  • the outlet 16 is, however, in the upper region, ie in the vicinity of the edge 19 of the container 2. In this way and Way are separated by the cleaning process debris, debris or other contaminants on the overhead drain 16 is removed.
  • an overflow 17 is provided, so that the ultrasonic cleaning system can be flushed with fresh transfer medium 3, as indicated by the arrow 18.
  • a hollow body 12 can be slipped or placed on the transmission element 9. Subsequently, the vibrating plate 5 is vibrated by means of the ultrasonic generator 4, whereby the transmission element 9 mounted on the vibrating plate 5 is vibrated. By the vibrations of the transmission element 9 cavitation bubbles are generated in the inner region of the hollow body 12, which clean the inside of the hollow body 12. At the same time cavitation bubbles are generated in the transmission medium 3 by the vibrations of the vibrating plate 5, in particular in the radially outer region, which clean the outside of the hollow body 12. By varying the vibration frequency generated by the ultrasonic generator 4, the power intensity between the vibrating plate 5 and the transmission element 9 can be shifted, resulting in a shift in the intensity of the cleaning of the outside relative to the inside of the hollow body 12.
