Patent number: 4347134Abstract: A slurry separator utilizes the power inherent in the pressurized slurry from the slurry pump through a reaction nozzle to drive a rotor, with the slurry distributed through the nozzle being distributed over the surface of a conical grid. The rotor structure also drives squeegee-like blades which scrape the solids downward inside the cone readying screen for the next discharge, and then sweeping them down into a cylindrical auger chamber where they are compacted downwardly against an inverted conical floor to further squeeze moisture through the sides of a housing cylinder. The conical floor of the compacting cylinder presses up against the particulates to be compacted with a resistance that is proportional to the speed of the rotor, achieved through the use of a centrifugal governor. This action makes it tolerant to variations in nozzle flow volume (pressure) and converts energy output into optimum separation.Type: GrantFiled: September 3, 1981Date of Patent: August 31, 1982Inventor: Oswald C.
