Abstract
1,149,689. Screw centrifuges. BIRD MACHINE CO. 6 Sept., 1967 [9 Sept., 1966], No. 40731/67. Heading B2P. In a continuously operating solid bowl centrifuge comprising a solids discharge screw conveyor 10 rotatable at a velocity different from that of the bowl 1 and having, in operation, a portion of its length completely immersed in the pool 14 of separated liquid, separation efficiency is increased by providing at a free radial distance 18 from the conveyor 10 an independently rotatable symmetrical body 15 which, in operation, is immersed in the liquid pool 14 and serves to accelerate feed slurry rapidly to, or above, bowl speed. The accelerating body 15 is rotatably supported in overhung fashion by means of a shaft 16 rotatably mounted in a hollow shaft 7 of the bowl 1 and is independently driven at a higher rotational speed than that of 'the bowl or conveyor. The body 15 may have a cylindrical or conical outer wall 17 and is provided with a conical inner wall 20 onto which slurry fed from a pipe 19 impinges and is accelerated before its introduction into the pool of liquid where during its flow along the space 18 it is further accelerated by the body 15. Apertures 3 and 5 are for the discharge of solids and liquid respectively. The helical blades of the screw conveyor 10 are mounted in the conical portion of the conveyor on a drum 11 whereas in the cylindrical portion thereof they may be unsupported, as shown, or partially supported by means of bars.
