Abstract
The apparatus comprises a periodic wave generating unit driving at least a piezoelectric transducer for generating ultrasounds, which latter includes a base block associated with a passage conduit and wherewith there are associated a plurality of piezoelectric buttons or pads interposed between different polarity electric contacts electrically coupled to the generating unit and clamped against the base block by means of a counter-block.
Claims4
An ultrasonic assembly for the ultrasonic treatment of liquids comprising a pre-atomizer having a casing and a partition wall in the casing defining two chambers, a bridge conduit having a first end connected to a first of said chambers and another end connected to a second of said chambers, a final atomizer located downstream of said pre-atomizer and having an outlet end, piezoelectric transducers mounted on said pre-atomizer and said final atomizer, a pumping element having a suction conduit and a delivery conduit, said suction conduit of said pumping element being connected to one of said chambers, and said delivery conduit of said pumping element being connected to said final atomizer, and a recirculation conduit having a first end connected to said outlet end of said final atomizer and a second end connected to said suction conduit of said pumping element.
