  • Method and apparatus for separating solid particles from a mixed fluid stream
    Patent number: 3985522
    Abstract: Method and apparatus for separating solid particles from a mixed fluid stream is provided by this invention. The method comprises helically guiding a fluid mixture of particles and liquid into a porous-walled chamber, discharging the fluids centrifugally from the chamber and recovering the particles at the bottom of the chamber. Apparatus, in accordance with the present invention, includes a helical conduit, in fluid flow connection with a porous chamber, a spiral deflector extending from the top of helical conduit downwardly into the chamber so as to deflect the particles downwardly as the water is ejected centrifugally through the sides of the chamber.
