Definitions

  • the subject of the present invention is a centrifugal liquid separator, more particularly intended for use in the dairy industry, but which can also be used for mineral or vegetable oils or for other liquid mixtures, the effect of force. centrifugal acting on said liquids to separate their constituents having different densities.
  • liquids of different densities separated by centrifugation by means of the apparatus are directed upwards inside concentric annular conduits formed in the rotating part of the machine, in order then to be sent into different destinations through conduits made in the fixed head of said machine.
  • the fixed head of the machine is very simplified and the seal between the various axial conduits is obtained using profiled rings, movable relative to the fixed parts of the machine and which come into contact with fixed rings. relative to the rotating parts of the machine, under the effect of the pressure itself of the liquids which acts on these movable rings, which makes it possible above all to obtain a considerable simplification of the hydraulic circuits while making it possible to eliminate the presence of springs of any type, thereby facilitating the control and maintenance of the machine.
  • the liquid to be treated enters the centrifugal separator through the central duct 1 to come out, in the state separated from its two phases with different specific weights, through the co-axial ducts 2 and 3.
  • phase with lower specific gravity which goes up through the innermost co-axial duct 2 is brought to the duct co-axial 4 provided in the fixed head of the machine to lead into outlet outlets, while the phase with the highest specific weight which rises through the external co-axial duct 3 escapes through the outlet mouth 5 formed in the fixed part of the machine.
  • the seal between the central inlet duct 1 and the first co-axial outlet duct 2 is ensured by the ring 6, which is fixed to the central part 7 of the rotor and against which the movable ring is applied. 8, provided co-axially to the central duct 1, which ring comes through its upper lip 8 'in contact with the fixed ring 6, under the effect of thrust of the pressure of the liquid in the duct 1, pressure which is exerted according to the direction indicated by the arrows 9.
  • the stop circlip 10 carried by the central tube which forms the duct 1 limits the movements of the movable ring 8 in the direction of opening.
  • the external seal is also ensured by the movable ring 17 provided co-axially with the outlet mouth 5 and limited in its movements by the stop circlip 18 carried by the outer wall of the tube which forms the mouth 5 and by the fixed ring 19 welded to the head 20 of the machine.

  1. Trennzentrifuge mit auf dem oberen starren Kopf drehbar angebrachten Dichtungsmitteln, die einen Drehkörper bildet, in dessen Inneres die zu behandelnde Flüssigkeit eingefüllt wird, während die durch unterschiedliche Dichten getrennten Phasen ins Innere konzentrischer ringförmiger Zuleitungen aufsteigen, dadurch gekennzeichnet, daß die Dichtungsmittel, die eine Trennung der unterschiedlichen Flüssigkeitsphasen gewährleisten, durch Ringe (8, 13, 14, 17) gebildet werden, die gegenüber den feststehenden Teilen der Maschine durch den Eigendruck der auf die beweglichen Ringe einwirkenden Flüssigkeit bewegbar und axial verschiebbar sind, insbesondere durch den Ring (8) auf dem Rohr, das die mittlere Leitung (1) bildet, die Ringe (13 - 14) auf einem mittleren koaxialen Rohr (4), den Ring (17) auf dem äußeren Rohr, das die Ausgangsöffnung (5) bildet, um einen Kontakt mit den Ringen (6, 11, 19) herzustellen, die gegenüber den drehbaren Teilen der Maschine starr angeordnet sind, um auf diese Weise die Dichtigkeit zwischen der Leitung (1) für den Einlaß der zu behandelnden Flüssigkeit und den Leitungen (4, 5) zum Auslaß der durch die Zentrifugalkraft getrennten Flüssigkeiten Zu garantieren.
  2. Trennzentrifuge nach Anspruch 1, dadurch gekennzeichnet, daß die Kühlung der Dichtungsringe durch die in der Maschine behandelten Flüssigkeiten erfolgt.
