Continuous ultrasonic cleaning apparatus

摘要

A continuous ultrasonic cleaning apparatus having excellent cleaning efficiency and holding/carrying capability of the product-to-be-cleaned is disclosed. The apparatus enables the speed of the conveyors to be increased, forced drying to be achieved and no stain nor water marks are formed even if water is used as a cleaning agent. The continuous ultrasonic cleaning apparatus utilizes a cleaning agent receiving/storage bath having a cleaning agent supplying/adding function for the cleaning bath positioned therebelow and an ultrasonic oscillator. Net conveyors for holding the product-to-be-cleaned are used and synchronized for carrying the product-to-be-cleaned. A high-speed air blower is mounted at a down-stream side of the cleaning bath. Even if water or pure water is used as a cleaning agent, the ultrasonic efficiency is high. When using the high-speed blower to dry the cleaning agent, the product is securely retained at its original position. No stain nor water marks are formed and an equivalent cleaning quality can be achieved as that when using fulone. Furthermore, by using an oxygen-free water and purging inert gas for the entire receiving/storage bath, any product having a propensity to be easily corroded can be effectively cleaned.
