ABSTRACT:
A continuously operated liquid-solids separator for separating a powdered resin material suspended in water forming a slurry by permitting the resin, which is of a lower specific gravity than the water, to float or be impelled upwardly within a separator vessel or upright tank from which it is withdrawn through an outlet orifice as a thickened slurry. Anti-swirl baffles in the form of vertically extending plate members are located in circumferentially spaced relationship interiorly of the vessel in at least the upper regions thereof in order to restrict the undue agitation and swirling of the resinous material and limit resultant downward movement thereof as it floats upwardly within the liquid towards the outlet orifice, while agitation is imparted to the thickened slurry in the uppermost region of the separator vessel through the intermediary of a suitable rotatable impeller mounted in the upper section of the vessel proximate and at a level below the outlet orifice in order to maintain the accumulated resin or particulate material uniformly dispersed in the thickened slurry as the latter is being withdrawn from the separator. A generally horizontal stilling baffle or screen extends across the separator vessel between the inlet orifice for the solids-liquid suspension or slurry and an outlet orifice for the purer or clarified liquid located proximate the bottom of the separator.
