Abstract

1,144,183. Centrifugal separators. PENNSALT CHEMICALS CORP. 19 Oct., 1966 [20 Oct., 1965; 2 Sept., 1966], No. 46695/66. Heading B2P. In a centrifuge of the hollow screw-conveyor type having a feed tube 20 for supplying material to be centrifuged to the interior of the screw-conveyor 18, Figs. 1 and 3, and one or more discharge tubes 30 extending radially from the conveyor for feeding the material from the latter into the bowl, the or each discharge tube is provided with a terminal nozzle opening 40 directed towards the solids discharge end of the centrifugal bowl 12. The bowl is driven by a pulley P and the conveyor is driven by the bowl at a different speed through gearing C. The speed differential may be regulated by a backdrive pulley B. A baffle plate 22a deflects the feed material towards the discharge tubes 30. Each discharge tube is provided with an annular rib 34 by means of which the tube is clamped by a plate 36 into a 'boss 32 surrounding a tube opening 28 in the conveyor. The opening 40 on each discharge tube 30 is disposed radially beyond the outermost level of the liquid discharge port 14 and radially inwardly of the outer edge of the screw flights 18a. In the modification shown in Fig. 4, each discharge tube 56 has an enlarged flange 58 which abuts against a shoulder on the conveyor 181 and is secured thereto by bolts. The inside surface of the tube may be coated with an abrasive resistant material or, preferably as shown, a sintered tungsten carbide insert 62 may be secured into the tube by means of an epoxy resin. Another form of discharge tube is described.
