VERTICAL CENTRIFUGAL SEPARATOR

PROBLEM TO BE SOLVED: To provide a vertical centrifugal separator capable of easily performing the maintenance of an outer cylinder and an inner cylinder. SOLUTION: The vertical centrifugal separator is equipped with the outer cylinder 1 rotatable around an axial line extending in an almost vertical direction, the inner cylinder 5 provided in the outer cylinder to be rotatable around the axial line in the same direction so as to generate a predetermined difference in the number of rotations with respect to the outer cylinder 1, a screw flight 3 attached to the outer peripheral surface of the inner cylinder 5 and arranged so as to form a slight gap with respect to the inner wall surface of the outer cylinder 1, a supply pipe 39 provided in the inner cylinder 5 and supplying a slurry to be treated to the separation chamber S between the outer and inner cylinders 1 and 5, a top plate 7 for supporting the outer and inner cylinders 1 and 5 in a suspended state, a support 9 and a support stand 11 and a cover member 13 for covering the periphery of the outer cylinder 1 in a freely detachable manner.
