Ultrasound vibrating rod is also called ultrasonic vibrating
rod. Compared with traditional ultrasonic vibrating plate, it has the characteristics of wider application scope and longer service life. In industrial applications, the use of ultrasonic vibration rods for cleaning, extraction, chemical reaction, scale prevention, water treatment and so on is a very mature and widely used technology.
Ultrasound vibrating rod utilizes the alternating period of positive and negative pressure that exists in the transmission process of ultrasound. In positive phase, the medium molecules are squeezed to increase the original density of the medium. In negative phase, the medium molecules are sparse and discrete, and the density of the medium decreases. Ultrasound vibrating rod can produce ultrasonic wave uniformly around 360 degrees, and the output of energy is not affected by the changes of liquid level, temperature difference and other loads. Ultrasound vibrating rod generally includes high-power ultrasonic transducer
, horn, tool head (launcher), which is used to generate ultrasonic vibration and send this vibration energy to liquid. Shoot. The transducer converts the input electric energy into mechanical energy, i.e. ultrasound. Its form of expression is that the transducer moves back and forth longitudinally, and its amplitude is usually several microns. Such an amplitude power density is not enough and can not be used directly. The horn amplifies the amplitude according to the design requirements, isolates the reaction solution and transducer, and also plays the role of fixing the whole ultrasonic vibration system. The tool head is connected with the horn, which transmits the vibration of ultrasonic energy to the tool head, and then transmits the ultrasonic energy to the chemical reaction liquid by the tool head.
