Shrouded drum skimmer

Patent ·
OSTI ID:5919645

A drum-type skimmer for separating substances of different polar characteristics with greater efficiency is described. A shroud is disposed radially from the lower portion of a submerged drum so as to increase the cohesive action between the substance to be removed and the surface of the partially submerged drum. An arcuate shroud defining approx. 90/sup 0/ arc is secured radially from and adjacent to the lower portion of the peripheral surface of the drum. The shroud is positioned so as to be disposed below the liquid level and to extend above the liquid level. The radial spacing between the shroud and the outer surface of the drum is selected for an effective cohesive action between the liquid to be skimmed and the outer surface of the drum. (2 claims)
