Assembly to homogenize dispersions of granular solids, to separate noble metals from sludge, has ring-shaped circular segments with ultrasonic power converters to break down the sludge by cavitation

摘要

The assembly (65) to homogenize a dispersion of granular solids, e.g. earth or mineral and clay sludge, has ring-shaped circular segments (12-12d) with surfaces (33) at its outer circumference (25) to hold ultrasonic power converters (16, 16a). The right angled surfaces are tangential to the inner zone (18) in the central axis direction (19). The ultrasonic units are in pairs on a water-cooled cooling body, through drilling passages (24, 24a) at both ends (21) of the surfaces, to extend into the inner zone, separated by an air gap. The segments are held in place by inflow (3) and outflow (4) covers screwed together, to form a closed working zone (34) containing a rotating reflector (17) of parabolic segments (18S).
