Liquid/solid separator with a conduit between a vortex and a quiescent collector zone

摘要

A separator for separating solids from liquids in a liquid/solid mixture. The mixture is injected into a tubular separation barrel in a helical stream which flows to a spin plate. The spin plate reverses the axial direction of flow and forms a vortex whose central portion flows in the opposite axial direction. An exit port adjacent to the spin plate permits flow of solids-enriched liquid into a collection chamber. The collection chamber has a collection region below the exit port to collect solids and a quiescent zone above the exit port into which liquid relieved of much of its solids can rise. A conduit connects the quiescent region to a central point on the spin plate facing into the separation barrel to create a flow path from the quiescent zone to the separation chamber.
