Definitions

• the invention relates to a method for cleaning filamentary or band-shaped products, in particular wire, by means of ultrasound via an ultrasound sonotrode and a liquid according to DE 196 02 917.1-15.
• the known methods for example for cleaning wire, use immersion transducers which are introduced into containers filled with liquid.
• the ultrasonic energy of the submersible transducer is radiated into the liquid. It occurs in the liquid Cavitation, ie liquid breaks apart due to the high energy, bubbles form, the inside 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 soiled surface of the items to be cleaned and removes residues such as fats, oils or the like.
• a method is also known in which a generally known cylindrical feed-through sonotrode is used, through which a feed-through in which the wire to be cleaned is guided is passed.
• the cleaning liquid is atomized and in chambers and in the implementation with broke the wire.
• the sonotrode does not come into contact with the cleaning agent.
• the sonotrode must excite a relatively large volume of water so that the sound energy concentration is too low to achieve sufficient cleaning performance.
• the ultrasound does not work directly enough on the surface of the wire to be cleaned.
• DE 196 02 917.1-15 describes a generic method, according to which the product to be cleaned is passed through a bore in a special ultrasonic sonotrode which vibrates in the air and into which cleaning liquid flows.
• the object of the invention is to develop a method for cleaning thread-like or band-shaped products, which ensures that the ultrasound acts directly on the product to be cleaned.
• 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 continuous wire is guaranteed.
• the ultrasound acts within the working bore from all sides at a short distance and over an irr.
• the ultrasonic sonotrode relatively long distance intensively on the wire surface.
• a 20 to 100 times the intensity of the sound power (based on the sound-emitting surface) is achieved compared to the known methods, so that a substantially greater km power is achieved with, for example, wire cleaning with a comparable energy expenditure.
• the method according to the invention is for cleaning a wire, for cleaning a plurality of wires, also in the composite of a strand, and also for cleaning fabric strips, metal strips, ropes or the like. applicable with high effectiveness.
• the appropriate ultrasonic power can be selected and used for every wire diameter range or for every type of material.
• the vibration amplitude of the bending vibrator can be adjusted depending on the application.
• a bending vibrator 3 is shown in a schematic sectional illustration, which is excited by an ultrasonic sonotrode 1 to ultrasonic vibrations US.
• the bending vibrator 3 has a first bore 2 along the longitudinal axis through which the product to be cleaned, e.g. Wire.
• the first bore 2 is connected to further bores 4 in the area of the vibration node SK of the bending oscillator 3.
• These holes 4 are arranged perpendicular to the hole 2 and serve to supply a suitable cleaning liquid.
• the sonotrode 1 and the bending oscillator 3 vibrate in the air with an amplitude set as a function of the product to be cleaned.
• the sonotrode 1 excites the bending oscillator 3 in a point or line shape on the line of a constant amplitude.
• the sonotrode is preferably rectangular, but a round sonotrode 1 can also be used.
• It can also be fabric tapes, metal tapes, ropes or the like. cleaned or pretreated for further processing.
