Abstract
A screen for separating solids and liquids is formed from parallel strips of wedge wire or similar material into a substantially cylindrical two-sided enclosure in a generally C-shaped profile. Unfiltered liquid containing solids contacts the screen surface on both the convex and concave sides of the C-shaped enclosure. The unit may be placed in a vessel adapted to accommodate two such C-shaped devices in concentric relationship. The vessel may function similar to a candle filter, or a more conventional flow may be used.
Claims20
A device for separating solids from liquids comprising a generally cylindrical enclosure, the generally cylindrical enclosure having an axis, and a first substantially cylindrical screen member within said generally cylindrical enclosure, said substantially cylindrical screen member also having an axis, said axis being coexistent or substantially parallel to the axis of said cylindrical enclosure, said substantially cylindrical screen member comprising a convex screen and a concave screen, said convex screen and said concave screen being connected in sealed relationship and defining a space between them whereby, when said substantially cylindrical screen member is contacted with liquid containing solids, at least some solids will be retained on said screen member and said liquid will pass through said convex and concave screens to said space.
A solids/liquid separator comprising a first generally cylindrical screen having a screen surface facing outwardly, a second generally cylindrical screen of a diameter smaller than that of said first screen and having a screen surface facing inwardly, said second screen being situated substantially concentrically within said first screen, said first and second screens being connected in sealed relation to form a generally C-shaped profile and a space between said first and said second screens for collecting liquid filtrate.
A substantially cylindrical device for separating solids and liquids comprising (a) a substantially cylindrical convex wedge wire screen and (b) a substantially cylindrical concave wedge wire screen, said substantially cylindrical concave wedge wire screen being fixed and sealed substantially concentrically within and apart from said substantially cylindrical convex wedge wire screen, whereby said convex and concave screens form an interior space.
