The automatic vacuum hydrocarbon cleaning machine is mainly composed of an ultrasonic cleaning tank and an ultrasonic generator. The ultrasonic cleaning tank is made of solid and elastic stainless steel, and the bottom is equipped with an ultrasonic transducer vibrator; The ultrasonic generator generates high-frequency and high-voltage, which is transmitted to the transducer through the cable connecting line. The transducer and the vibrating plate jointly generate high-frequency resonance, so that the solvent in the cleaning tank is subjected to ultrasonic action. The action of cleaning dirt.
When the sound pressure or intensity reaches a certain level, the bubble will expand rapidly and then suddenly close. In this process, a shock wave is generated at the moment when the bubble closes, resulting in a pressure of 1012-1013pa around the bubble and local temperature regulation. The huge pressure generated by this ultrasonic cavitation can destroy the insoluble dirt and make them differentiate into solutions. Direct and repeated effects of steam cavitation on fouling.
The ultrasonic generator converts alternating current into ultrasonic frequency power. Its frequency range is generally 16khz-68khz, up to 1000khz. The power is then transmitted to the sensor by cable. Ultrasonic transducers are usually composed of several parallel sound heads. Here, the electric energy is converted into mechanical vibration energy of the same frequency and transmitted to the cleaning tank, so as to form an ultrasonic sound field that vibrates back and forth in the cleaning solution.
In the ultrasonic field, a large number of micro vacuum bubbles are formed in the negative pressure area of vibration due to the late supply of surrounding liquid. When the barotropic pressure comes, the microbubbles suddenly close under pressure, and the violent collision between liquids produces a huge shock wave, which can form thousands to tens of thousands of atmospheres and instantaneous high temperature. This is the "cavitation" effect of ultrasound. Cavitation has good cleaning and emulsifying effects, and can separate the oil stains on the surface of the cleaned workpiece, so as to achieve the purpose of rapid cleaning
In addition, the size of the cleaning object determines the size of the cleaning basket, thus determining the type of equipment required. In order to make ultrasonic wave play a role in all aspects, it is recommended to select equipment with a slightly larger volume, which also provides room for future expansion. The difficulty of cleaning depends on the geometry of the object to be cleaned and the type of contamination. For complex cleaning tasks, it is recommended to add pretreatment steps such as steam cleaning or spray cleaning. The heated cleaning solution can shorten the cleaning time and remove pollutants faster. Therefore, ultrasonic cleaning equipment with heating device is usually used for cleaning various cleaning materials.
