When the standard vibrating screen is used to screen some special and difficult-to-screen materials, it is easy to cause some problems such as blocking the net. Therefore, for some special materials, ultrasonic vibrating screen (with ultrasonic device on the vibrating screen) is used. However, some customers may mistakenly say that the acoustic wave vibrating screen is in the process of inquiry. Here I will explain to you the difference between ultrasound and infrasound: Ultrasound and infrasound we can’t hear 2. Ultrasonic information is used to obtain a communication application, which is called ultrasonic detection. For example, the thickness of the object is measured by pulse reflection of the ultrasonic wave in the medium. Ultrasonic cleaning and application: First, the principle of ultrasonic cleaning Ultrasonic cleaning is a physical cleaning. The cleaning solution is placed in a tank to apply ultrasonic waves in the tank. Since the ultrasonic wave is a dense vibration wave like the sound wave, the pressure of the medium alternates during the propagation process. In the negative pressure region, a force of tearing is generated in the liquid, and a bubble of vacuum is formed. When the sound pressure reaches a certain value, the bubble rapidly grows, and in the positive pressure region, the bubble is crushed and closed due to the pressure. At this time, the liquid collides with each other to generate a strong shock wave. Although the displacement and speed are very small, the acceleration is very large, and the partial pressure can reach several thousand atmospheres. This is the so-called cavitation effect. Second, several factors affecting the cleaning effect 1. Relationship with frequency: The lower the general frequency, the more obvious the cavitation effect, but the noise is relatively high, which is suitable for objects with relatively flat surfaces. The higher the frequency, the worse the cavitation effect, but the noise is relatively low, which is suitable for objects and electronic crystals with many micro-hole blind holes. 2. Temperature-related: Generally, the medium temperature of 30 ° C - 50 ° C is best. 3. Related to sound intensity: According to the frequency, the sound intensity is generally chosen to be around 1-2 w/cm2. 4. It is related to the cleaning solution: in general, the lower the viscosity of the cleaning solution, the higher the gas content and the better the cleaning effect. 5. It is related to the depth of the cleaning liquid and the position of the object to be cleaned. Third, the application of ultrasonic cleaning in various fields Because ultrasonic cleaning itself has unparalleled superiority in other physical cleaning or chemical cleaning, it is widely used in many fields such as service industry, electronics industry, pharmaceutical industry, laboratory, machinery industry, hard alloy industry, chemical industry, etc. A brief introduction to individual industries. 1. Application in the service industry. In daily production, glasses and jewelry can be cleaned with ultrasonic waves. It is fast and harmless. Large hotels and restaurants use it to clean tableware. It not only has good cleaning effect, but also has the effect of killing viruses. It is well known that to obtain particles of different sizes, the crushed material is ground in a ball mill and sieved through layers of different specifications. After the sieve is used for a long time, the sieve hole will be blocked (such as diamond sieve). Brushing by other methods will destroy the sieve, and the effect is not satisfactory. After many manufacturers' tests, ultrasonic cleaning will not damage the sieve but also the sieve. The blocked particles are completely recovered. Ultrasonic cleaning technology has been widely used in many pharmaceutical companies, especially for the cleaning of vials, oral liquid bottles, ampoules, large infusion bottles, and cleaning of butyl rubber stoppers and natural rubber stoppers. For the cleaning of bottles, ultrasonic cleaning technology is used to replace the original brushing machine, which is realized by the processes of inverted water injection, ultrasonic cleaning, internal and external washing, air drying, and turning. 4. Ultrasonic cleaning of the filter element We know that no matter what kind of filter or filter of any kind, after a period of use, the permeability will be reduced due to impurities, and the average filter price is lower, but for the chemical fiber industry, Only the imported filter element, the price is nearly 10,000 yuan, it is a pity to abandon it. The ultrasonic filter cleaning machine developed by us in cooperation with other scientific research units uses a concentrating ultrasonic cleaning machine, which can concentrate the energy above 1KW on the radiation surface of 200×20mm2. The ultrasonic intensity is high, and the blockage can be quickly removed. At the same time, the device uses a reverse filter device. As long as you provide the core, we can provide you with a complete cleaning device. (The equipment takes 10-15 minutes to wash a filter element). Applicable to PP cotton filter, activated carbon filter, hollow fiber filter ceramic membrane filter. 5. Ultrasonic cleaning of metal It is well known that after the metal bar is extruded into a wire, the outer part of the wire often has a layer of carbonized film and oil. It is difficult to remove the dirt (especially the whole wire) by acid cleaning or other cleaning methods. The ultrasonic wire washing machine is According to the actual production needs, a continuous wire-cutting and high-efficiency cleaning equipment is used. The rough washing part is composed of a cleaning liquid storage tank, a transducer, a circulation pump, a filter and a matching piping system. After the wire is ultrasonically washed and washed, And then blow dry to complete the entire cleaning process. The whole set of equipment integrated control is simple, convenient and effective. It is widely used in other wires such as silk, tungsten wire, molybdenum wire, silk wire and copper wire (before insulation coating). 6. Application of ultrasonic cleaning technology in phosphating treatment The pre-spraying process of the product is very important. The general traditional process uses acid to treat the workpiece, which has serious environmental pollution and poor working environment. At the same time, the biggest drawback is that the residual acid after pickling and rust removal of complex structural parts is difficult. Rinse well. After the workpiece is sprayed, the time is not long, and rusting occurs along the crack, which damages the surface of the coating and seriously affects the appearance and internal quality of the product. Ultrasonic cleaning technology is applied to the pre-painting treatment, which not only can quickly peel off the dirt on the surface and the gap of the object, but also the coating layer of the coating is firm and does not return to rust.

Ultrasound technology is one of the common technologies based on physics, electronics, mechanics and materials science. Ultrasound technology is accomplished through the physical processes of ultrasonic generation, propagation, and reception. Ultrasonic waves have characteristics such as bunching, orientation, reflection, and transmission. According to the different sizes of ultrasonic vibration radiation, it can be roughly divided into:
1. The use of ultrasonic waves to change the power of an object or physical property is called power ultrasound. For example, a large enough energy is generated in the liquid to cause cavitation, which can be used for cleaning and emulsification.
2. Ultrasonic application in the micro-powder industry
3. Ultrasonic application in the pharmaceutical industry
Ultrasonic cleaning is available in all walks of life. The above are only representative industrial applications, and many new industries and fields can use ultrasonic cleaning. We look forward to the joint development and exploration by the majority of users and manufacturers.
