Hydrocyclone separator arrangement

A cleaning system for liquid suspensions comprising an elongated combination feed and accept header having a plurality of hydrocyclone separators detachably connected thereto and projecting outwardly therefrom in spaced apart relation therealong, each said hydrocyclone separator including an elongated separator chamber having a large end and an oppositely disposed small end with a reject outlet therein, the large end of the separator chamber having an annular rim, and a tubular outlet for accept material disposed at said large end in concentric relation to said annular rim, with an annular inlet for feed suspension into said separator chamber being defined between said annular rim and the tubular accept outlet, said feed and accept header including an outer wall and a dividing wall therein to separate feed suspension from accept suspension;

• a plurality of tubular accept nipples connected to said dividing wall in aligned spaced apart relation for fluid flow therethrough and each being sealingly detachably connected to a respective one of the tubular accept outlets of the hydrocyclone separators;
• a corresponding plurality of tubular feed nipples each surrounding a respective one of said accept nipples in spaced concentric relation therewith and connected to said outer wall of the feed and accept header for fluid flow therethrough and means for sealingly detachably connecting each feed nipple to a respective one of the annular rim portions at the large ends of the respective hydrocyclone separators, whereby feed suspension can pass toward the separator chambers of the hydrocyclones through the annular inlets between said feed and accept nipples while permitting accept suspension to pass from each separator chamber through said connected tubular accept outlets and accept nipples and thence through said dividing wall for flow through the feed and accept header.
