Ultrasonic cleaning system that achieves ultrasonic control tailored to the purpose.

This is an effective device using a dedicated ultrasonic tank (original manufacturing method). Due to the high efficiency of ultrasonic utilization, standard tanks lack sufficient strength and durability. Depending on the target and purpose, multiple ultrasonic waves and a degassing fine bubble generation liquid circulation device are controlled based on sound pressure measurement analysis for cleaning, stirring, and surface modification. We propose various combinations and usage (control) methods. The key point is to achieve an ultrasonic propagation state tailored to the target, focusing on the "dissolved oxygen concentration distribution" and "liquid circulation" within the dedicated tank. << Degassing Fine Bubble (Microbubble) Generation Liquid Circulation Device >> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gases to form. The above describes the state of the degassing liquid circulation device. 3) As the concentration of dissolved gases decreases, the bubble size of dissolved gases due to cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles (microbubbles) smaller than 20μ are generated.
