An improved support ring is disclosed for a polymer resin pellet dryer screen of the type which includes cylindrical screen sections interconnected by two semicircular bands forming a support ring or connecting band. The support ring is positioned in spaced relation to an exterior housing by brackets, and the screen encloses a driven bladed rotor for removing water from a slurry of water and pellets. The improved support ring comprises a two piece annular ring including a generally perpendicular, rigid flange attached to the exterior of a semicircular band pair. The flange rigidities the bands of the ring and supports the adjacent ends of the screen sections from the external housing to maintain the screen in cylindrical configuration and in concentric relation to the bladed rotor rotatably positioned within the screen.
A screen support for a cylindrical dryer screen in which the dryer includes a housing enclosing said screen, said screen support comprising a plurality of arcuate, substantially rigid members separably connected at end portions thereof and engaging, rigidifying and supporting said screen, at least one of said arcuate members including a radially outwardly extending flange in supporting association with said housing to support said arcuate members and said screen.
In combination, an upper cylindrical screen, a lower cylindrical screen, and a support ring between adjacent ends of said screens to maintain the screens in alignment and the adjacent ends in cylindrical configuration, said support ring including a connecting band and a radial outwardly extending rigid flange mounted to the connecting band for rigidifying said connecting band and adjacent ends of said screens.
A dryer including a cylindrical screen, a bladed rotor rotatably positioned within said screen and a support structure for said screen, said screen including a pair of cylindrical screen sections in aligned relation, said screen sections including adjacent ends, and connecting and supporting structure engaging and supporting said adjacent ends to maintain the cylindrical configuration of the screen sections and to maintain the screen in concentric relation to said rotor, said connecting and supporting structure for said adjacent ends of the screen sections comprising a substantially rigid cylindrical band engaged telescopically with said adjacent ends of said screen sections and a flange rigidly affixed to said band substantially around its circumference and extending radially outwardly and generally perpendicular in relation thereto thereby rigidifying said band to maintain the cylindrical configuration of the band and adjacent ends of said screen sections, and support members connected between said flange and said screen support structure.
