Abstract

1412035 Separating solid particles PHILLIPS PETROLEUM CO 6 March 1973 [7 March 1972] 10730/73 Heading B2H An apparatus for separating solid particulate material, e.g. granular polymer, comprises an inclined grid 10, means, e.g. a hopper 12 for feeding the material to be separated to the upper end 16 of the grid, a first collector positioned below the grid for collecting particulate material e.g. polymer pellets 26 passing therethrough, and a second collector positioned at the lower end 38 of the grid for collecting material, e.g. balled filaments 28 and elongated filaments 29, discharged from the upper surface 18 of the grid, one or more conduits 30, 36 being positioned adjacent the grid and being provided with a plurality of openings 32, 40 therealong for directing pressurised fluid into the material supported on the grid. The grid 10 is mounted in a casing 2. The conduits 30, 36 are positioned above and below the grid transversely to the direction of travel of the material down the grid and are connected to an air compressor 34. Streams of compressed air from the conduit openings 32 and 40 are directed respectively along and through the grid to facilitate separation of the pellets 26 from the filaments 28, 29. A blower 20 may provide a stream of air for removing fines from the pellets. The grid 10 is formed of elongated and curved elements 42 which may be corrugated and which may be tensioned. Removable spacers 44 may be positioned between adjacent elements to adjust the width of the gap A between the elements. Some or all of the grid elements adjacent the conduit 36 may have at least one abrupt change in width forming a stepped grid upper surface.
