Definitions
- the present invention relates to 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 different 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.
- sealing rings are directly licked by the constituents of the liquids treated in the machine, which results in the absorption of the heat produced by the movement of said rings and avoids the need to have to ensure their cooling using the water circulation provided for in the aforementioned patent application.
- the single figure of this drawing is a partial axial section showing the upper part of the centrifugal separator according to the invention.
- 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.
- the 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 highest specific weight phase which rises through the outer 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 provided 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 the opening.
- the external sealing is 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.
