Definitions

  • the invention relates to a device for emitting ultrasound energy into a liquid by means of a rod-shaped or tubular, sound-emitting part with the length lambda / 2 or a multiple thereof, which is coupled with an end face to a sound transducer which executes longitudinal vibrations.
  • the sound transducer is attached to the wall of a liquid container so that the sound-emitting part is in the liquid.
  • the longitudinal vibration transmitted to the sound radiating part by coupling to the sound transducer is partially converted into transverse vibrations so that the ultrasonic energy is radiated both in the longitudinal direction of the resonator and radially.
  • only radial radiation is desired; the radiation emanating in the longitudinal direction, that is to say from the end face of the rod-shaped or tubular, sound-emitting part, cannot normally be utilized.
  • the aim of the invention is therefore to provide a device which largely avoids this longitudinal loss radiation, that is to say causes the longitudinal vibration fed into the sound-radiating part by the sound transducer to be effectively converted into a radial transverse vibration.
  • This is achieved in a manner according to the invention in that a further longitudinal transducer which executes synchronous longitudinal vibrations to the first transducer is coupled to the free end face of the sound-emitting part.
  • the sound-radiating part has a free end that emits undesired longitudinal vibrations, but at this previously free end, according to the invention, a further similar and similar-vibrating sound transducer is attached or coupled, which not only emits in the longitudinal direction of the sound-radiating Partly prevented, but which also feeds ultrasonic energy into the sound-emitting part.
  • a further similar and similar-vibrating sound transducer is attached or coupled, which not only emits in the longitudinal direction of the sound-radiating Partly prevented, but which also feeds ultrasonic energy into the sound-emitting part.
  • Such a device can therefore radiate twice the ultrasonic energy radially into the liquid with the same geometric dimensions without any loss of power resulting from longitudinal vibrations.
  • the sound-emitting part can be made of solid material or as a hollow body.
  • the use of solid material has the advantage of a longer service life, since the cavitation pitting does not have as destructive effects here as with a hollow body.
  • the hollow body on the other hand, has a somewhat more effective effect due to the larger vibration amplitude.
  • the transducers can vibrate both in common and in push-pull.
  • the decisive factor here is the length of the sound-emitting part of the device, which can be either an integer even or an odd integer of lambda / 2. This allows an optimal adaptation of the length of the device to the selected container size.
  • Identical, synchronously vibrating sound transducers are arranged on the end faces of a sound-emitting part (1) made of solid material.
  • the transducers are completely encapsulated so that the entire device can be immersed in liquid.
  • the device can be attached on one side to the wall of a container. The encapsulation of the sound transducers prevents longitudinal vibrations from being released into the surrounding liquid by their counterweights.
  • the two sound transducers (5, 6) vibrate synchronously and, for example, in synchronism. In this way, a longitudinal vibration is transmitted to the sound-emitting part (1), which is converted in a known manner into a transverse, radially radiating vibration.
  • the length (1) of the sound-emitting part is lambda / 2 or an integer multiple thereof.
  • Fig. 2 shows an essentially identical device, but with a tubular, sound-emitting part (11).
