Abstract
Abstract A liquid-solids separator comprising a rotating drum having a perforated peripheral surface immersed in the liquid. Liquid is drawn in through the peripheral screen and discharged through an axial pipe. A reverse flush is provided by an elongated liquid jet directed against the interior of the perforated wall and enmeshed particles are removed by an outside scraper blade or by a rotating outer brush. The device is particularly adapted for use in the reservoir of a gas washing unit for removing particulate material from the wash liquid.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
181 words
A liquid-solids separator adapted to separate solids from liquid while immersed in said liquid comprising a drum having a perforate peripheral wall and end closure members adapted to be immersed in the liquid, a discharge pipe communicating with said drum through one of said end closure members for discharging liquid which has passed inwardly through said perforate wall, means for rotating said drum about said discharge pipe, a supply pipe within said drum concentric with said discharge pipe and extending axially into said drum having an elongated discharge opening and vanes disposed on opposite sides of said opening and having wing members extending outwardly therefrom with their discharge edges adjacent said perforate wall and spaced apart to form an elongated fixed liquid jet within said drum adapted to direct a jet of liquid against said wall, a perforate brush mounted on a hollow shaft for rotation outside of said drum with its periphery contacting the outer surface of said perforate wall and means to supply wash liquid to said shaft, and a sludge conveyor in said liquid for removing solids therefrom.
Claim 2
Dependent Claim

A liquid-solids separator adapted to separate solids from liquid while immersed in said liquid comprising a drum having a perforate peripheral wall and end closure members adapted to be immersed in the liquid, a discharge pipe communicating with said drum through one of said end closure members for discharging liquid which has passed inwardly through said perforate wall, means for rotating said drum about said discharge pipe, a supply pipe within said drum concentric with said discharge pipe and extending axially into said drum having an elongated discharge opening and vanes disposed on opposite sides of said opening and having wing members extending outwardly therefrom with their discharge edges adjacent said perforate wall and spaced apart to form an elongated fixed liquid jet within said drum adapted to direct a jet of liquid against said wall, a perforate brush mounted on a hollow shaft for rotation outside of said drum with its periphery contacting the outer surface of said perforate wall and means to supply wash liquid to said shaft, and a sludge conveyor in said liquid for removing solids therefrom.
Claim 3
Dependent Claim
23 words
Apparatus as set forth in claim 1 in which said last mentioned end closure member is journalled for rotation about said discharge pipe.
Claim 4
Dependent Claim
32 words
Apparatus as set forth in claim 1 in which parallel ribs are formed on the contacting surfaces of said wings for effecting a closure with said perforate wall as the drum rotates.
Claim 5
Dependent Claim
31 words
Apparatus as set forth in claim 1 in which a drive shaft is carried by the other of said end closure members and projects inwardly to rotate in said inlet pipe.
Claim 6
Dependent Claim
20 words
Apparatus as set forth in claim 1 in which gear means are provided for driving said brush from said drum.
Claim 7
Dependent Claim
28 words
Apparatus as set forth in claim 1 in which a scraper blade is mounted to contact the outer surface of said perforate wall for removing trapped particles therefrom.
Claim 8
Dependent Claim
26 words
Apparatus as set forth in claim 1 in which an outer jet is provided to wash the outer surface of said perforate wall for cleaning purposes.
Claim 9
Dependent Claim
28 words
Apparatus as set forth in claim 1 in which said drum is immersed in the liquid in a reservoir and is mounted to turn about a vertical axis.
Claim 10
Dependent Claim
29 words
Apparatus as set forth in claim 1 in which said drum is immersed in the liquid in a liquid reservoir and is mounted to turn about a horizontal axis.
Claim 11
Dependent Claim
23 words
Apparatus as set forth in claim 9 in which said horizontal axis of said drum extends parallel to the movement of said conveyor.
Claim 12
Dependent Claim
35 words
Apparatus as set forth in claim 10 in which said horizontal axis of said drum extends across the path of movement of said conveyor and said drum is mounted to be driven by said conveyor.
Claim 13
Dependent Claim
18 words

Claim 15
Dependent Claim
47 words
Apparatus as set forth in claim 1 in which the peripheral surface of said drum is formed by a plurality of spaced, parallel bars extending axially of said drum around the periphery thereof and by a wire wound helically around said bars to form an open mesh.
Claim 16
Dependent Claim
26 words
Apparatus as set forth in claim 14 in which said bars are triangular in cross-section with the points of the triangle extending inwardly of said drum.
Claim 17
Dependent Claim
