  • Patent number: 6918494
    Abstract: An arrangement of hydrocyclones, resulting in a greater density of hydrocyclones packaged in a given volume. One or more overflow extensions is secured to the overflow portions of one or more hydrocyclones to permit individual hydrocyclones to be placed into an axially staggered arrangement with respect to each other. By keeping the larger hydrocyclone heads from being directly adjacent that of a neighbor's, the maximum diameter of the hydrocyclones no longer becomes a limitation on the proximity of one hydrocyclone to another. The inlet section of one of a group of hydrocyclones is disposed to be adjacent either the separation portion of an adjacent hydrocyclone or an overflow extension, thereby permitting denser packaging. In another aspect, groups of axially staggered hydrocyclones are axially offset from and intermeshed with one another, permitting greater density in packaging.
