Abstract
A vertical centrifugal separator includes a casing, a bowl that is rotatably housed in the casing and provided to separate a solution to be processed which is supplied to an interior of the bowl into a liquid and a solid by an action of centrifugal force and discharge the liquid and the solid, and a discharge assembly that is rotatably housed in the bowl and provided to discharge the solid in the bowl. The bowl and the discharge assembly each have an engagement portion that is engaged or disengaged when the bowl and the discharge assembly are moved relative to each other in an axial direction and a position adjustment mechanism for adjusting a phase between the discharge assembly and the bowl relative to a rotation axis, for example, at a single relative position.
Claims10
A vertical centrifugal separator, comprising:
- a casing;
- a bowl serving as a rotatable cylindrical body rotatably housed in the casing, the bowl separating a solution to be processed which is supplied to an interior of the bowl into a liquid and a solid by an action of centrifugal force, the liquid and the solid being discharged from respective discharge portions;
- and
- a discharge assembly rotatably housed in the bowl, the discharge assembly discharging the solid from the bowl,
- wherein the bowl and the discharge assembly form a single-end supported structure in which a first axial end of each of the bowl and the discharge assembly is rotatably supported and a second axial end of each of the bowl and the discharge assembly is a free end,
- wherein each of the bowl and the discharge assembly has an engagement portion that is engaged or disengaged when the bowl and the discharge assembly are moved relative to each other in an axial direction and a position adjustment mechanism which adjusts a phase between the bowl and the discharge assembly relative to a rotation axis of the bowl and the discharge assembly to at least a single relative position so that the bowl and the discharge assembly are positioned in consideration of a dynamic balance when the bowl and the discharge assembly are integratively rotated,
- wherein, when the solution to be processed is separated by the action of centrifugal force, the bowl and the discharge assembly integrally rotate in an engagement state in which the phase adjusted by the position adjustment mechanism is held, and the bowl and the discharge assembly are allowed to rotate relative to each other when the engagement state is released,
- wherein the bowl includes a bowl shell having a substantially cylindrical tank shape, to which the solution to be processed is supplied, and a hollow rotation shaft integrated with an upper portion of the bowl shell,
- wherein the discharge assembly includes a wing assembly having a plurality of wings formed integrally with the wing assembly and contained in the bowl shell and a rotation shaft protruding upward from the wing assembly and rotatably disposed in the hollow rotation shaft of the bowl, and
- wherein the engagement portion of the bowl is disposed on a lower side of the bowl and has a tapered portion that is tapered such that an inner diameter of the bowl increases in a downward direction, and the engagement portion of the discharge assembly is disposed on a lower side of the discharge assembly and has a tapered portion that is tapered such that a width of the discharge assembly increases in a downward direction;
- and when the discharge assembly moves upward relative to the bowl, the engagement state is established in which the bowl is driven to rotate and rotates integrally with the discharge assembly.
