ABSTRACT:
In a substantially conventional system for receiving and conveying a fluid suspension of material there is an endless porous belt screen on which the material is spread and a tray beneath the belt to catch liquid which passes through the belt. A suction box beneath the belt near the area of deposition draws off some liquid. Superimposed on the conventional system is a resonant frequency energy source in the form of a roll assembly consisting in part of an outer shell in the form of an exterior cylindrical roll supported on shock mounts and in constant engagement with the underside of the belt. The exterior cylindrical roll is driven at a circumferential speed equal to the linear speed of travel of the belt. Within the exterior cylindrical roll is a frequency generator mass in the form of a generator roll sub-assembly embodying an eccentric coupling driven by an oppositely rotating shaft which oscillates the generator roll sub-assembly to generate a sinusoidal force motion in the sonic range, whereby to set up in the exterior cylindrical roll the belt sections adjacent thereto and the material on the belt a resonant condition which in turn generates accoustical vaporous cavitation to break surface tension of the liquid and the material thereby to augment the quantity of liquid passing through the belt.
