Abstract
A separator for separating solids from a slurry has a vibrating rotating container, rotatably connected to a support. The rotating container is provided with at least a first inlet and at least a first outlet and has at least one opening. A screw press is at least partly provided inside said rotating container. The screw press is arranged through said first outlet. The screw press has at least one hole. The at least one hole and a feed screw are provided inside said rotating container in continuation of said screw press. At least one lift paddle is provided inside said rotating container. A first part of the lift paddle is arranged along an inner surface of a side wall of said rotating container. A second part of said lift paddle is in contact with a part of the feed screw. A new method for separating slurry uses a separator.
Claims11
A separator for separating solids from a slurry comprising
- a rotating container (103, 203) comprising a side wall (131) and two end walls (123a, 123b) where said rotating container (103, 203) is arranged on a support;
- where said rotating container (103, 203) is rotatably connected to said support;
- said rotating container is provided with at least a first inlet (129) and at least a first outlet (150);
- said rotating container (103, 203) comprises at least one opening (135);
- a feed (141) and screw press (145) being at least partly provided inside said rotating container (103, 203), where said feed (141, 241) and screw press (145) is arranged through said first outlet (150) and said screw press (145) comprises at least one hole;
- said at least one hole (148, 248) being provided on a part of said screw press (145) being inside said rotating container (103, 203);
- at least one lift paddle (137a, 137b, 237) being provided inside said rotating container (103, 203), where a first part of said lift paddle is arranged along an inner surface of said side wall (131) of said rotating container (103, 203) and a second part of said lift paddle is superposed at least a part of said feed screw (141, 241) wherein
- an independent transport screw (143, 243) is arranged coaxially with said feed (141, 241) and press screws (145, 245), where said transport screw (143) is controlled independently from said screw press (145) on the basis of the torque measured on the screw press axle.
