Ultrasonic device

Abstract

The invention discloses an ultrasonic device which comprises a controller and at least three transducers. The ultrasonic device is characterized in that a rectifying circuit, a filter circuit, an inverter circuit, a main oscillator, a frequency division device, a pulse amplifier and a control power source are arranged in the controller, the input end of the rectifying circuit is connected with an AC220V power source, transmitting heads of the transducers are made of steel 45, a body of the ultrasonic device is made of Fe-Co alloy, the ultrasonic device can be directly arranged through welding on the outer surface of a part to be processed through ultrasonic waves without shutting down the device due to the fact that the transmitting heads of the transducers are made of the steel 45, and therefore the ultrasonic device is easy to install; in addition, under the strong excitation current provided by the controller, the metal format of bodies of the transducers can change, contract vibration can be generated, spreading losses of the ultrasonic waves in metal are small, and therefore the ultrasonic device is small in loss and good in effect; therefore, the ultrasonic device has the advantages of being small in loss, convenient to install and good in effect.

Description

technical field [0001] The invention relates to an ultrasonic device. Background technique [0002] The sound waves with a frequency higher than 20000 Hz are ultrasonic waves, which have the characteristics of high energy and straight-line propagation, and are widely used in various technologies. Existing ultrasonic devices usually include a controller and a transducer; the transducer includes a body and a transmitter, and the working principle of the controller is more complicated. It is ceramic. [0003] At present, existing ultrasonic devices cannot be directly connected to equipment that requires ultrasonic treatment. For example, when the existing ultrasonic devices are used in boilers, pipelines of water-based heat exchange equipment, etc., when descaling and anti-scaling are used, or when they are used in seawater pipes to prevent marine organisms, first of all, the need to carry out The ultrasonic treatment equipment is shut down, and then the transducer can be co...

Problems solved by technology

Existing ultrasonic devices usually include a controller and a transducer; the transducer includes a body and a transmitter, and the working principle of the controller is more complicated. is ceramic

[0003] Currently, existing ultrasonic devices cannot be directly connected to equipment requiring ultrasonic treatment

For example, when the existing ultrasonic devices are used in boilers, pipelines of water-based heat exchange equipment, etc., when descaling and anti-scaling are used, or when they are used in seawater pipes to prevent marine organisms, first of all, the need to carry out The ultrasonic treatment equipment is shut down, and then the transducer can be connected to the equipment that needs ultrasonic treatment after using auxiliary parts, or changing the structure of the boiler cylinder, pipeline, and seawater pipe. Similarly, when overhauling the ultrasonic device , also need to stop the equipment for ultrasonic treatment, it can be seen that the existing ultrasonic device has the disadvantage of being inconvenient to use

[0004] In addition, when the existing ultrasonic device is working, when the sound wave is transmitted to the equipment requiring ultrasonic treatment through the transmitter of the transducer, the loss of the sound wave in the transmitter is relatively large, and the body made of ordinary metal , when it works, the eddy current is relatively large, the temperature is relatively high, and the amplitude is relatively small, resulting in relatively large loss of ultrasonic waves and relatively poor effect
