Definitions

  • the invention relates to an arrangement for the ultrasonic cleaning of a plurality of juxtaposed, strand-like products such. Wires, profiles and tubes by means of an ultrasonic excited liquid according to the preamble of claim 1.
  • the cleaning effect is based, as with all ultrasonic cleaning, on the principle of cavitation.
  • the ultrasonic energy is radiated into the cleaning liquid, which encloses or surrounds the material to be cleaned.
  • the liquid cavitation occurs, i. Liquid breaks down due to the high energy, bubbles are formed, the interior of which is filled with negative pressure gas. The gas bubbles implode, releasing high energy and creating a strong microflow. This flow acts on the soiled surface of the material to be cleaned and removes residues such as fats, oils, stearates, dusts and the like.
  • the known methods for injecting ultrasonic energy into liquids with the aim of cleaning a plurality of juxtaposed strand-like products include plate immersion vibrators which are placed in containers filled with liquid.
  • the ultrasound energy The immersion transducer is irradiated over a large surface using low vibration amplitudes, ie up to 2 microns (microns), and low surface acoustic power densities, ie up to 1 watts per square centimeter (W / cm 2 ) in the cleaning fluid.
  • the string-like products to be cleaned which are to be cleaned, are drawn through the fluid of a large container, usually a basin.
  • the cleaning effect is not satisfactory and for use in round cross sections of the products to be cleaned, such as e.g. Wires and pipes unsuitable.
  • the width of the plate vibrator does not work on the curved surface of round cross sections.
  • the directly introduced sound power is only used in a small area. It must be used for cleaning several ultrasonic transducers.
  • DE 19706 007 C2 describes a method according to which the product to be cleaned is guided through a bore of a special bending vibrator which vibrates in the air and which is excited to vibrate by an ultrasonic sonotrode, into which cleaning liquid flows.
  • the object of the invention is to develop an arrangement for ultrasonic cleaning of several adjacent running, strand-like products such as wires, profiles and pipes, with which it is ensured that the introduced ultrasound of an ultrasonic transducer acts directly on the product to be cleaned and thereby achieves efficient cleaning is that only the liquid volume necessary for cleaning is excited with ultrasound, each of the adjacent running, strand-like products should be applied as uniformly as possible with ultrasound.
  • AT 350 493 B describes a method and apparatus for cleaning wires, pipes and rods in a liquid medium exposed to macro-sound.
  • the cleaning is in this case achieved in that the material to be treated is passed through a bore of a vibrating in the longitudinal axis of the bore horn through which simultaneously with the good in the same or opposite direction, a good enclosing the liquid medium is passed.
  • An arrangement of several holes transverse to the main vibration direction is not apparent from this solution.
  • the arrangement according to the invention is characterized in that in an along its longitudinal axis (x-axis) in air vibrating ultrasonic sonotrode with a thickness of more than ⁇ / 4, holes transversely (y-axis) to the main vibration direction (x-axis ) of the sonotrode are arranged for the implementation of the product to be cleaned, which are located at the outer edge of the sonotrode and approximately in series and at any distance from each other, so that the cleaning liquid in the bores both by the vibrations along the main vibration direction (x-axis) as is also excited by the thickness vibrations of the sonotrode material transversely to the main vibration direction (z-axis), wherein the cleaning fluid is supplied to the bores such that it fills them completely.
  • the core of the invention is an arrangement for the ultrasonic cleaning of a plurality of juxtaposed strand-like products, e.g. Wires, profiles and tubes by means of an ultrasonic excited cleaning liquid in a bore (3) of a sonotrode (1), which only slightly, i.
  • the ultrasonic sonotrode (1) with a thickness of more than a quarter of the sound wave oscillating along its longitudinal axis a plurality of bores (3) transversely to the longitudinal axis of the sonotrode (1 ) are arranged for the implementation of the product to be cleaned, which are located on the outer edge of the sonotrode (1) and approximately in series and at any distance from each other, wherein the holes (3) fully filling cleaning fluid in the holes (3) both by the vibrations along the longitudinal axis as well as by the thickness vibrations of the sonotrode material transversely to the longitudinal axis of the sonotrode (1) can be excited.
  • the ultrasound has an intensive effect on the surface of the material to be cleaned from all sides within the working bores. It is achieved 20 to 100 times the surface peel density compared to the known methods, so that with a comparable energy consumption, a much higher cleaning speed, for example, in the wire cleaning is achieved. It also saves cleaning liquid needed a smaller plant and reached a higher flow rate of the material to be cleaned. The environmental impact is reduced by the more efficient use of energy and the lower consumption of cleaning additives.
  • the arrangement according to the invention is suitable for the efficient cleaning of a plurality of juxtaposed strand-like products, e.g. Wires, profiles and tubes, but also several strands, applicable.
  • the appropriate ultrasonic power can be selected and used.
  • the oscillation amplitude of the sonotrode can be adjusted depending on the application.
  • FIG. 1 is a schematic sectional view of an ultrasonic sonotrode 1 is shown, which is excited by an ultrasonic transducer 2 to ultrasonic oscillations US along its longitudinal axis (x-axis).
  • a "thick" sonotrode with a rectangular or approximately rectangular cross-section with a thickness of ⁇ / 4 up to ⁇ / 2 is chosen in order to achieve an effectiveness both as a longitudinal oscillator and as a thickness oscillator.
  • holes 3 occur in a suitable arrangement of the holes thickness vibrations (z-axis), in arranged in the oscillation maximum bores 3 longitudinal vibrations (x-axis) occur.
  • longitudinal vibrations (x-axis) occur according to the distance of the bore 3 from the maximum vibration superpositions of longitudinal vibration components (x-axis) and thickness vibration components (y-axis). This ensures that each hole 3 undergoes an approximately equal application of ultrasonic power.
  • two sonotrodes 1 offset from each other can be arranged one behind the other.
  • the length of the sonotrode 1 is an arbitrary multiple of ⁇ / 2.
  • the sonotrode 1 has along the longitudinal axis (x-axis) a plurality of bores 3 in the upper and lower edge region through which the product to be cleaned, e.g. several adjacent wires 4, are performed.
  • the holes 3 may have different diameters and may be arranged at different distances from the outer edge of the sonotrode 1, where appropriate a Distance between the bore outer edge and the outer edge of the sonotrode 1 is selected between about 2mm to about 8mm, and the distance between the holes 3 may be selected differently.
  • the bores 3 of a row on the outer edge of the sonotrode 1 are sufficient.
  • the second row of holes 3, which should contain in each case symmetrically arranged holes with respect to the central axis of the sonotrode 1, serves to increase the service life of the sonotrode 1, which is subject to wear as a result of the cavitation effect. It also serves to comply with the symmetry conditions of sound propagation.
  • the sonotrode 1 can be reversed on wear of the holes 3 on one side and continue to be used by the use of the holes 3 on the other side.
  • the sonotrode 1 oscillates in the air with an amplitude set depending on the product to be cleaned.
  • the sonotrode 1 is preferably rectangular, but it can also be a round sonotrode 1 are used.
  • ⁇ / 2 is about 125 mm when using titanium as the sonotrode material.
  • the sonotrode 1 is selected with a cross section of, for example, 100 mm ⁇ 100 mm and an arbitrary length of a multiple of ⁇ / 2, for example of 2000 mm.
  • 100 bores 3 with a diameter of 10 mm per row are arranged in the sonotrode 1.
  • each bore 3 is subjected to about 40 watts of ultrasonic power. This corresponds to a power of about 14 watts / cm 3 bore volume.
  • the bore volume is about 7.85 cm 3 and is again reduced by about 5 cm 3 at a wire diameter of 8 mm, so that about 2.85 cm 3 cleaning fluid per hole 3 are to be stimulated.
  • Cleaning baths used according to the prior art achieve a volume sound power density of 0.015 to 0.03 watt / cm 3 .
