Definitions
- the invention relates to an arrangement for the ultrasonic cleaning of a plurality of strand-shaped products running side by side, such as e.g. Wires, profiles and tubes by means of a liquid excited by ultrasound according to the preamble of claim 1.
- the cleaning effect is based on the principle of cavitation.
- the ultrasonic energy is radiated into the cleaning liquid, which encloses or flows around the material to be cleaned. Cavitation occurs in the liquid, i.e. Liquid breaks apart due to the high energy, bubbles form, the interior of which is filled with gas under negative pressure. The gas bubbles implode, releasing high energy and creating a strong micro flow. This flow acts on the contaminated surface of the items to be cleaned and removes residues such as fats, oils, stearates, dusts and the like.
- Known methods for the irradiation of ultrasonic energy in liquids with the aim of cleaning a plurality of strand-shaped products running side by side include plate immersible transducers which are introduced into containers filled with liquid.
- the ultra Sound energy of the immersible transducers is radiated into the cleaning liquid over a large surface using low vibration amplitudes, ie up to 2 micrometers ( ⁇ m), and low surface acoustic power densities, ie up to 1 watt per square centimeter (W / cm 2 ).
- W / cm 2 low surface acoustic power densities
- the cleaning effect is unsatisfactory and for use with round cross sections of the products to be cleaned, e.g. Unsuitable wires and pipes.
- the width of the plate transducers does not affect the curved surface of round cross sections.
- the directly introduced formwork performance is only used in a small area. Several ultrasonic transducers must be used for cleaning.
- DE 19706 007 C2 describes a method according to which the product to be cleaned is guided through a bore in a special bending oscillator which vibrates in the air and which is excited to oscillate by an ultrasound sonotrode, and into which cleaning fluid flows.
- the object of the invention is to develop an arrangement for ultrasound cleaning of several strand-shaped products running side by side, such as wires, profiles and pipes, with which it is ensured that the ultrasound introduced by an ultrasound transducer acts directly on the product to be cleaned and efficient cleaning This is achieved in that only the liquid volume required for cleaning is excited with ultrasound, with each individual one of the strand-shaped products running next to one another being subjected to ultrasound as uniformly as possible.
- the solution to this problem results from the features of claim 1.
- the arrangement according to the invention is characterized in that in an ultrasonic sonotrode vibrating in air along its longitudinal axis (x-axis) with a thickness of more than ⁇ / 4, bores transverse (y-axis) to the main direction of vibration (x-axis ) of the sonotrode for the passage of the product to be cleaned, which are located on the outer edge of the sonotrode and approximately in series and at any distance from one another, so that the cleaning liquid in the bores both due to the vibrations along the main direction of vibration (x-axis) and is also excited by the thickness vibrations of the sonotrode material than transverse to the main vibration direction (z-axis), the cleaning liquid being fed to the bores in such a way that it completely fills them.
- the ultrasound power that is introduced is concentrated on this small volume, so that an intensive cavitation field is created with little energy expenditure, in which a highly effective cleaning of the product passing through is guaranteed.
- the ultrasound intensely affects the surface of the material to be cleaned from all sides within a short distance from the working holes.
- a 20 to 100 times the surface formwork power density is achieved compared to the known methods, so that a substantially higher cleaning speed, for example in wire cleaning, is achieved with a comparable energy expenditure. It also saves cleaning fluid, requires a smaller system and achieves a higher throughput speed of the items 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 for the efficient cleaning of several strand-like products running next to one another, such as e.g. Wires, profiles and tubes, but also several strands can be used.
- the appropriate ultrasonic power can be selected and used for each cross-section or for each type of material.
- the vibration amplitude of the sonotrode can be adjusted depending on the application.
- FIG. 1 shows a schematic sectional illustration of an ultrasound sonotrode 1 which is excited by an ultrasound transducer 2 to ultrasound vibrations US along its longitudinal axis (x-axis).
- a “thick” sonotrode with a rectangular or approximately rectangular cross section with a thickness of ⁇ / 4 to ⁇ / 2 is selected as the sonotrode 1, so that effectiveness is achieved both as a longitudinal oscillator and as a thickness oscillator.
- thickness vibrations occur in bores 3 arranged in the vibration node of the ultrasonic vibrations US
- longitudinal vibrations occur in bores 3 arranged in the vibration maximum.
- superpositions of longitudinal vibration components (x-axis) and thickness vibration components (y-axis) occur. This ensures that each bore 3 experiences approximately the same exposure to ultrasound power.
- two sonotrodes 1 can be arranged offset one behind the other.
- the length of the sonotrode 1 is an arbitrary multiple of ⁇ / 2.
- the sonotrode 1 has a plurality of bores 3 in the upper and lower edge region along the longitudinal axis (x-axis) through which the product to be cleaned, e.g. several wires 4 running side by side are guided.
- the bores 3 can have different diameters and can be arranged at different distances from the outer edge of the sonotrode 1, expediently one
- the distance between the outer edge of the bore and the outer edge of the sonotrode 1 is chosen between approximately 2 mm to approximately 8 mm, and the distance between the holes 3 can be selected differently.
- the holes 3 in a row on the outer edge of the sonotrode 1 are sufficient for the function of the arrangement.
- the second row of bores 3, which should each contain bores arranged symmetrically with respect to the central axis of the sonotrode 1, serves to increase the life of the sonotrode 1, which is subject to wear due to the action of cavitation. It also serves to maintain the symmetry conditions of sound propagation.
- the sonotrode 1 can be turned over on one side when the bores 3 wear and can be used further by using the bores 3 on the other side.
- the sonotrode 1 vibrates in the air with an amplitude set as a function of the product to be cleaned.
- the sonotrode 1 is preferably rectangular, but a round sonotrode 1 can also be used.
- ⁇ / 2 is approximately 125 mm when using titanium as the sonotrode material.
- the sonotrode 1 is selected with a cross section of, for example, 100 mm x 100 mm and any 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 approximately 40 watts of ultrasonic power. This corresponds to an output of approximately 14 watts / cm 3 bore volume.
- the bore volume is approximately 7.85 cm 3 and is reduced by a further 5 cm 3 with a wire diameter of 8 mm, so that approximately 2.85 cm 3 of cleaning fluid per bore 3 are to be excited.
