Self-purging centrifuge (10) for liquid/liquid/solid separation. It is useful in industries such as metal working where separation of a lighter liquid from a heavier liquid is achieved simultaneously with the separation of suspended solid particles, without requiring the use of a pre-filter. The centrifuge (10) includes a rotatable drum (11), a driven rotor disc-assembly (22, 24, 25) mounted within the drum (11), extension means (50) for guiding the separated heavier liquid, apart from the separated lighter liquid, from the drum (11), separate collection chambers (48, 53) and purge rods (65) for assisting in the removal of collected solids from the drum side wall (12). Rotation of the drum (11) causes solid particles to collect on the drum side wall (12). Heavier liquid is separated from and flows upwardly apart from the lighter liquid. Lighter liquid moves inwardly, travelling upwardly through the disc assembly (22. 24, 25). Purging of the collected particles is accomplished through an eroding, washing action. |
