Abstract:
A method for separating and removing heavy particles from a fluid using a centrifugal device, comprising:positioning an inner cylinder within an outer cylinder to form a fluid flowpath between the exterior of the inner cylinder and the interior of the outer cylinder;directing the fluid to travel from one end of the fluid flowpath to the other end of the fluid flowpath while the cylinders are rotating;forming the outer cylinder with a thick-shelled wall having a width and a plurality of cut away indented pyramidal voids comprising a depth, wherein the depth of the cut away indented pyramidal voids is substantially the same or about the same as the width of the thick-shelled wall;forming a respective nozzle within each pyramidal void to allow transport of heavy particles from the fluid through the respective nozzles to an external receiving containment; andallowing the fluid to travel through the fluid flowpath while simultaneously transporting the heavy particles through the outer cylinder by cooperation between the sloped surfaces of the pyramidal voids and the respective nozzles.
