Abstract
An ultrasonic cleaning assembly for cleaning large objects immersed in liquid within a chamber, such as an array of elongated ultraviolet lamps within an ultraviolet purification tank. The cleaning assembly includes an elongated ultrasonic transducer extending across the width of the chamber and having a width appreciably smaller than the length of the chamber and the objects therein to be cleaned. Motor-driven apparatus is provided for moving the transducer within the chamber in such a manner as to direct the ultrasonic waves emitted by the transducer to all interior portions of the chamber, thereby applying the ultrasonic cleaning effect over the entire extent of all the objects within the chamber. In a first embodiment the transducer is moved linearly in a horizontal direction across the length of the chamber, and in a second embodiment, the transducer is centrally mounted within the chamber and is rotated about its longitudinal axis.
