    Centrifuge for separation of a mixture of solid particles, a specifically heavier liquid, and a specifically lighter liquid into the three component parts, having a conveyor helix 3 for moving the solid particles to one end of the drum 1, and, at the other end of the drum, a paring system, i.e. a centripetal pump 18, for removing one of the liquids under pressure and a catchment 24 for the removal of the other liquid without pressure. In order to permit removal of either the heavier phase (FIG. 1) or the lighter phase (FIG. 2) by the paring system a separating disk 6, 7 is disposed adjacent each end of the drum. The separator disks project radially outwardly from the helix and extend through the lighter liquid and partially through the heavier liquid. Each disk is provided with a closable opening at the level of the zone of separation. A weir for the overflow of liquid to go to the catchment 24 is provided by a conduit 21 having an open end disposed adjacent the solids discharge end of the drum. In operation, the opening in one of the separating disks is closed while the other is left open, and, depending on which disk has the closed opening, the heavier liquid or the lighter liquid goes to the paring system. The weir 20 of the paring system is replaceable.

    The invention relates to a technique for the processing of liquid and bulk products by centrifugation. The known centrifugal centrifuge, which contains a screw with branch tubes placed in the auger of the auger., Two separate disk, intake device. . The disadvantage of this centrifuge is the impossibility of transferring the fraction of the mixture under pressure, which limits the scope of use of the device. end cover drum. a chamber with an intake tube for draining one of the liquid fractions separated from the separation zone by an overflow bor. However, the known centrifuge does not allow selective removal under pressure by the intake tube of the liquid fraction of the mixture with a lower specific gravity, which complicates the operation of the device and limits the scope of its use. The aim of the invention is to provide selective removal under pressure of the intake tube of one of the liquid fractions of the mixture. This process is achieved by WTO in a precipitation centrifuge to separate a two-phase liquid mixture containing a solid fraction, including a body horizontally mounted for rotationally rotatable cylindrical drum , a screw placed in the end cover of the drum chamber with a suction tube for the removal of one of the liquid fractions, separated from the separation zone by an overflow side, also located in the face Drain cover for drainage of another liquid fraction mounted on the auger between the separation zone and the clarification zone. Separation disk and overflow device of the auger are provided with an additional separator disk located on the end cover of the drum in the liquid discharge zone, the peripheral part of which is placed in the liquid fraction with large specific gravity, with the separating discs having at least a hole, closed by a threaded plug and located at the interface of the fractions, and in the chambers for removing one of the liquid fractions before the pick-up tube ukreplenkoltsevoy overflow board. FIG. Figure 1 shows a centrifugal centrifuge for separating a two-phase liquid mixture containing a solid fraction with a longitudinal section; in fig. Figures 2 and 3 of the drum faceplate (on an enlarged scale) with the removal of the fraction with different specific weight. The precipitation centrifuge includes a housing 1, a cylindro-conical drum 2 horizontally mounted for rotation, a screw 3 a chamber 5 with a suction pipe 6 placed in the end cover 4 of the drum to drain one of the liquid fractions, separated from the separation zone by overflow 7. In the end cover k of the drum there is also a drain cavity 8 for discharging another liquid fraction, and on the screw 3 a separating disk 9 is mounted between the zone of separation and the zone of clarification. In addition, the screw is equipped with spiral blades 10 and located near the torus. oic drum cover in the zone of discharge liquids additional Sec / mtelNym disc 11, the peripheral part of which is placed in the liquid fraction with higher specific; the separating discs have at least one hole 12, 13i closed by a threaded plug T and located at the interface of the fractions, and in the chamber 5 for removing one of the liquid fractions, the annular overflow board is fixed in front of the intake tube. When this drain cavity 8 through the channels 15 is in communication with the catching cavity 16, as well as with one or more bypass tubes 17, forming an overflow device and held along the auger through its blade. For supplying the mixture to the centrifuge, there is a pipeline 18 connected to the screw chamber 19, which is provided with openings 20 for feeding the mixture into the separation cavity. For removal of solid fragments of the mixture, discharge holes 21 and 22 are made, respectively, in drum 2 and body 1. Rotation of the drum and screw with different speeds is provided by the drive 23.
    The device works as follows.
    The liquid mixture / feed through the pipeline 18, from the chamber 19 through the holes 20 enters the cavity of division between the screw and the drum. The discarded solid fraction is captured by the blades of the helix 10, the auger rotating at a speed different from the speed of rotation of the drum 2 is transported to the conical part of the drum to unload
    holes 21 and is discharged from the center
    reefs.
    A more severe fraction of the mixture flows around the cork-enclosed 1 disk 11 and into the chamber 5 of which it is removed under pressure; by means of a suction pipe 6. Chamber 5 is equipped with a replaceable iridescent board of 7 g which is Installed; It has a 24 phase boundary, depending on the difference in the density of the liquids to be separated in the separation cavity.
    The lighter fraction of the mixture falls through the holes 12 in the disk 9 into the zone of the conical part of the drum and through the pipes 17 passes into the drain cavity 8, from which it flows through the channels 15 without pressure into the cavity 16 (Fig. 2).
    Separation disc 11 with closed
    holes 13 prevents the light fraction from entering the chamber 5.
    If it is necessary to retract the lighter fraction under pressure, the openings 12 of the separation disc 9 are closed with stoppers, and the openings 13 of the disc 11 are opened. In this position (Fig. 3), the lighter fraction through the holes 13 of the disk 11 above the overflow board 7 flows into the chamber 5,
    from which it is removed from the centrifuge through a tube 6 under pressure. The tri fraction encompasses the separating disk 9 and, through the tubes 17, first enters the cavity 8, from which
    channels 15 without pressure are drained into cavity 16 ..
    Thus, the proposed centrifuge provides selective removal under pressure of the intake tube of one of the liquid fractions of the mixture "
