Surface cleaning installation, using ultrasound with one or more sonotrodes

摘要

The sound emission face (2.1) of sonotrode (2) is slightly spaced from the surface to be cleaned and the sonotrode is relatively movable into the gap (5) between the cleaned face (1.1) and sound emission face opens a feed duct (6) for cleaning liquid, while a cover (4) is allocated round sound emission surface .The cover is applied to the cleaned face adjacent to sound emission face. The gap section under the cover is linked to an exhaust. Preferably a pressure chamber (4.1) is included in the cover.
