Definitions

  • the invention relates to a cleaning device for the ultrasound-assisted cleaning of stationary surfaces of use, with an ultrasound source and an ultrasound transmitter connected to it, hereinafter also referred to as ultrasound transducer.
  • the invention has for its object to provide a cleaning device of the type mentioned, with which larger areas can be cleaned as effectively as possible.
  • this object is achieved in a cleaning device of the type mentioned at the outset, which has a fluid film unit which is at least indirectly connected to the ultrasound transmitter and is designed to generate or hold a fluid film between the ultrasound transmitter and a surface to be cleaned.
  • the ultrasound source and the ultrasound transmitter preferably comprise at least one ultrasound generator, at least one ultrasound transducer and at least one sonotrode, the fluid film unit having a sealing device which is connected to the sonrode, the ultrasound transducer and ultrasound generator and is designed to form a fluid cushion between the sonotrode and a surface to be cleaned to obtain.
  • the sealing device preferably comprises a sealing lip system which is designed to move a limited fluid cushion over a usable surface to be cleaned and which is preferably at least two-shell.
  • the central sonotrode preferably has a feed for cleaning liquid.
  • the fluid film unit preferably comprises suction means for extracting excess fluids. These suction means are preferably provided within the sealing lip system.
  • the free end of the central sonotrode is preferably designed in the form of a beam-shaped bending oscillator. If the central sonotrode has an end surface facing the surface to be cleaned, this end surface is preferably essentially rectangular.
  • the cleaning device has a handle which enables the ultrasound cleaning device to be easily moved over the usable surface to be cleaned.
  • the cleaning device preferably has a power regulator for ultrasound power to be emitted, which can preferably be operated from the handle.
  • the cleaning device preferably comprises an adjusting device for a quantity of fluid to be supplied and / or extracted. This is preferably adjustable from the handle.
  • the cleaning device preferably has a limit value unit which is designed to set and detect limit values for switching off the energy and fluid supply.
  • An alternative cleaning device with a cleaning end surface facing a surface to be cleaned is characterized in that the cleaning end surface is designed as an array of individually excited sonotrodes, each with a round end surface.
  • a bending beam which is matched to the resonance frequency of the ultrasound used is preferably coupled at the end of the ultrasound transducer and can then be excited to bending vibrations in the ultrasound range.
  • a suitably dimensioned disk can also be fitted instead of the bending beam, which is also excited via an ultrasound sonotrode.
  • Both the beam as well as the plate transducer are preferably designed in a rectangular shape, so that right-angled room and facade corners can also be cleaned with such a cleaning system.
  • the bending beam or plate and in a preferred embodiment also the ultrasound-feeding sonotrode, are provided with a central bore through which the fluid adapted to the cleaning problem is supplied.
  • the bending oscillator (beam / plate) is mounted in a frame with the ultrasound transducer, so that the ultrasound vibrations generated are not transmitted to it.
  • the system can be stored and fixed in the vibration nodes of the ultrasound resonance system using suitable mechanical connections (e.g. pressing in, shrinking of bearing rings).
  • This storage frame is provided on its circumference with a highly flexible, abrasion-resistant sealing lip, which is preferably made of silicone rubber or polyurethane (Vulkollan), so that the liquid supplied can be held as a fluid cushion between the bending vibrator and the surface to be cleaned.
  • a further sealing lip is provided circumferentially to the first sealing lip, the space between the first and second sealing lip being connected to a suction device, so that fluid which emerges from the first sealing lip is then transferred the suction in the space between the first and second sealing lips can be sucked off.
  • this extracted fluid is returned to the fluid circuit via a suitable filter device, so that as little fluid loss as possible occurs through the process.
  • the fluid supply is further controlled via the control circuit of the sonotrode or via corresponding microswitches in the area of the sealing lips, in order to ensure that there is always sufficient fluid cushion for the cavitation process, on the other hand to ensure that when the cleaning head is lifted off the surface to be cleaned Fluid supply is interrupted to prevent uncontrolled leakage or to protect the system and the items to be cleaned from damage.
  • a mutually offset, linear array of power ultrasound transducers in the form of longitudinally oscillating composite transducers with flanged amplidans transformers can also be used, which are each provided with the cleaning liquid (for example tensides, Bases, acids, enzymes, special ultrasonic cleaning agents) can be supplied.
  • the cleaning liquid for example tensides, Bases, acids, enzymes, special ultrasonic cleaning agents
  • two coaxially arranged sealing lips serve to hold and then suck off the cleaning liquid. Due to the liquid cavitation, the vibrating sonotrode is lifted by a few hundredths of a millimeter from the cleaning material in a kind of hydrodynamic bearing. The high alternating pressures of a few kilobars that occur during cavitation clean the surface gently and efficiently.
