The invention refers to a disk package for a centrifuge rotor of a centrifugal separator adapted for separation of components in a supplied medium. The disk package comprises a plurality of separating disks (20) provided on each other in the disk package. Each separating disk extends around an axis of rotation for the centrifuge rotor and has tapering shape with an inner surface (22) and an outer surface (21) along the axis of rotation. Each separating disk has inner edge, defining a central opening of the separating disk, and outer edge. Each separating disk is manufactured of a material. The separating disks comprise a plurality of first separating disks (20') comprising a number of distance members (25), which extend away from the inner surface and/or outer surface. Each distance member comprises at least one contact zone (33) abutting an outer surface and inner surface, respectively, of an adjacent separating disk in the disk package. The contact zone has a continuously convex shape seen in a cross section.

A centrifuge with combinations of multiple features is disclosed. In one aspect, a centrifuge for removing more dense material from a fluid medium includes a fluid separation wall placed within a sleeve. The fluid separation wall rotates around the axis of rotation. A receptacle aids in separation of the more dense material from the fluid medium. The receptacle defined in a part by a respective geometry and a respective shape. An opening extends from the void area to the outer surface to transport the more dense material to the containment zone. An excitation apparatus associated with the receptacle creates a vibration within the receptacle. The centrifuge may further include a valve ring including a valve orifice the valve ring having a first position which blocks the more dense material from exiting the receptacle and a second position that allows the more dense material to move into the containment zone.

A self-cleaning rotor assembly (10) for a centrifugal separator can be thoroughly cleaned of accumulated solids without disassembly of the separator. The rotor assembly (10) comprises a fully welded, enclosed rotor body (12). The rotor assembly (10) has a double-ended, hollow axial shaft (16). The bottom end of the axial shaft (16) extends through the separator housing and has a high pressure fluid coupling. A plurality of spray nozzles (40) are fitted to the axial shaft (16) within the rotor body (12). The spray nozzles (40) are arranged to cover virtually all of the interior surfaces of the rotor (12).

The invention is intended, on the basis of the analysis of the experimental data with regard to a batch type centrifugal separator in prior art, to improve various functions by means of newly included mechanisms, so as to provide an organically combined high performance batch type centrifugal separator having the greatest level of perfection. The newly included mechanism improved in terms of technical functions over prior art are integrated as follows.
(1) Improvements in the mechanism of material supply: A flow of object liquid is improved by providing an auxiliary supply pipe (11) disposed within a hollow bore of a hollow rotating shaft (3), and by providing a deflector plate (13).
(2) Improvements in mechanisms in a separation tank (4): Functional effects of separation, sedimentation and peeling are improved by providing in the separation tank (4) a compulsive sedimentation device (5) and a fine particle peeling device (6).
(3) Improvements in the mechanism of discharging purified liquid and deposited fine particles: Discharge functions are improved by providing an anti-atomization device (16) in a purified liquid recovery passage (14, and by providing fine particle discharge port (5) at the lower end of the separation tank (4).
Thus, a high performance batch type centrifugal separator has been realized.
摘要:
A separator (222) for separating a first fluid of less density from a second fluid of greater density through rotation about an axis of rotation (292). The separator includes a separator chamber (350) mounted for rotation about the axis of rotation. A first weir (380) is positioned in fluid communication with the separation chamber. A second weir (400) is positioned over which the second fluid may pass to exit the separation chamber through a collection chamber (488). A fluid pressure chamber is positioned radially outwardly from the crest of the second weir to receive the second fluid as it passes over the second weir. The fluid pressure chamber is partially defined by an exit weir over which the second fluid may pass. A gas chamber (440) is postionned in the passageway between the second weir and the exit weir and includes a gas escape passageway.

L'appareil comporte, autour d'une bouche de distribution du mélange (29,30,16,15), une enceinte tournante étanche 1 dans laquelle une cloison annulaire 20 sépare deux chambres 23,24 communiquant entre elles par un passage périphérique 22, contenant principalement la phase lourde et la phase légère séparées et présentant des seuils 32, 33 de déversement de celles-ci. Suivant l'invention, les deux chambres sont équipées de dispositifs centrifugeurs distincts 17 et49, reliés à des dispositifs d'entraînement en rotation 14 et 11 les animant à des vitesses angulaires différentes. L'invention est applicable notamment à l'extraction des corps gras animaux et végétaux, à l'extraction des huiles essentielles, à la production de protéines animales dégraissées, à la récupération de polymères en milieu mixte solvant-eau, à l'extraction des antibiotiques, aux raffinages métallurgiques par solvants sélectifs, au dessalage de l'eau de mer par le procédé aux solvants, au traitement d'eaux résiduaires, etc.
