Ultrasonic cleaning device

Abstract

The invention discloses an ultrasonic cleaning device which comprises a cleaning tank. The cleaning tank is made of hollow transparent media. Cleaning liquid is contained in the cleaning tank. A heating constant temperature device is arranged in the cleaning tank. A liquid outlet hole is formed in the lower portion of the cleaning tank and is linked with an amplitude transformer. A transducer is arranged at one end of the amplitude transformer. By means of the manner, the ultrasonic cleaning device is simple and novel in structure; it is tested through experiments that cavitation is better facilitated through higher liquid temperature, however, if the temperature is too high, the steam pressure in bubbles is increased, and thus cavitation is weakened due to the fact that the buffering effect is enhanced when the bubbles are closed; thus, the heating constant temperature device additionally arranged in the ultrasonic cleaning device effectively enhances the ultrasonic cavitation effect, enhances the cleaning capability and improves the cleaning efficiency.

Description

technical field [0001] The invention relates to the field of ultrasonic appliances, in particular to an ultrasonic cleaning device. Background technique [0002] Ultrasound is a sound wave with a frequency higher than 20,000 Hz. It has good directionality and strong penetrating ability.

Ultrasound is named for its lower frequency limit greater than the upper limit of human hearing. In the electromechanical industry, there are cleaning requirements from mechanical parts to mechanical parts, from electrical parts to electrical parts, such as gears, crankshafts and even gearboxes, and electrical parts. The assembly of machinery and electrical appliances, as well as some precision mechanical parts and electrical parts, need to be cleaned. Most companies use traditional cleaning methods, such as immersion cleaning and spray cleaning. This cleaning method is not only labor-intensive, but also It is easy to cause environmental pollution and waste of water resources. Some enterprises can use ultrasonic cleaning to eliminate the disadvantages of traditional cleaning in technological transformation, especially for some mechanical parts with complex shapes, which are widely used.

At present, in the existing technology, ultrasonic cleaning uses the cavitation effect of ultrasonic waves in the liquid to vibrate and peel off pollutants such as oily particles on the surface of the cleaning object, so that the dirt layer is dispersed, emulsified, and stirred to achieve the purpose of cleaning. , however, the cavitation effect of ultrasonic cleaning devices currently on the market is relatively weak, and the cleaning ability is poor
