    This invention relates to centrifugal separators of the kind having sludge ports at the rotor periphery to be opened during operation and separate outlets for separated heavier liquid phase and separated lighter liquid phase. To reduce the losses of valuable lighter liquid phase during total discharge or partial discharge of the separator by opening the sludge ports, the centrifuge is provided with an overflow device connected to the heavy phase outlet, said overflow device having an inner annular overflow and also having a number of passages at a larger diameter than the inner overflow border. The passages are dimensioned to let through all heavier liquid phase in normal operation but not to let through an increased amount of heavier liquid phase fed to the separator just before opening the sludge ports for the purpose of displacing the interface between the heavier and the lighter liquid phase towards the rotor axis to a level that corresponds to said inner overflow border. In order to push the interface between the liquid phases inwards before discharge, no other action is therefore needed than an additional supply of the heavier liquid phase.

    The invention relates to devices for centrifugal separation of liquids.
    The closest to the invention to the technical essence and the achieved result is the separator, the upper body, the rotor with the central inlet for the mixture being processed, the separation chamber with openings for sludge removal, installed on its periphery, the first output chamber from the outlet) The first device and the internal overflow side, through which the first exhaust chamber is connected to the separation chamber, the second exhaust chamber and the annular overflow device, through which the latter is connected to the separation chamber, heavy liquid faei output device. Clj.
    However, an interface is formed in the device during operation, and the regulation of the radial position of the interface is the use of drain pipes in the outlet chambers of both liquid phases. A common tongue is typical for them, in which the entire fluid content in the rotor is thrown together with the collected sludge. In this case, the entire light phase inside the phase separation surface is lost with heavier impurities. One way to reduce the loss of the light phase would be to displace, with the help of non-rolling rings and disks, the interface between the phases towards the center. However, it is known that this will reduce the quality of separation of the liquid phase and, therefore, the ideal solution is to place the interface between the phases relatively far from the center during operation and move it inwards before release.
    . One of the objects of the invention is to achieve a modification of the separator such that the interface between the lighter and heavier liquid phases can move inwards toward the center of the rotor without the need for the valve to operate on the outlet side.
    The purpose of the invention is to reduce the loss of the light liquid phase by ensuring that the level of the interface between the light and heavy phases is shifted.
    The goal is achieved by the fact that in a centrifugal separator containing a housing, a rotor with a central inlet for the mixture being processed, a separation chamber with openings for sludge removal installed along its periphery, a first exhaust chamber with an output device and an internal overflow side through which the first the outlet chamber is connected to the separation chamber, the second outlet chamber and the annular overflow device, by means of which the latter is connected to the separation, in:) the outlet device of the heavy liquid phase, inlet The secondary pipe is equipped with an additional heavy phase supply pipe and a valve for alternately feeding the processed mixture and an additional heavy phase into the separation chamber, and the annular overflow device is made with channels located at a distance of the center of the rotor.
    FIG. 1 shows a centrifugal separator, a general view; in FIG. 2, the overflow device after moving the interface between the phases prior to release, the general view in FIG. 3 disk with holes, general view.
    The centrifugal separator consists of a central inlet pipe 1 of the treated mixture, which inside the separator is divided into three components: a slurry phase intermittently discharged through pipe 2 for sludge around the periphery of the rotor, a lighter liquid phase that is discharged through the exhaust pipe 3, and more severe liquid phase discharged through the outlet 4.
    The rotor consists of conical disks 5 having b holes of a certain diameter to form axial distribution channels for the liquid mixture added from the central inlet pipe 1 through the corresponding holes in the distributor 7.
    An exhaust chamber 8 for the separated lighter liquid phase communicates with the inside of the separation chamber 9 and is provided with a cleaning device 10 connected to the outlet 3 Another exhaust chamber 11 is equipped with a cleaning device 12 for outputting a heavier liquid phase to the outlet 4 and communicating with the chamber separation through the channels 13, made between the upper disk 14 and the rotor wall at the level determined by the outer diameter of this disk.
    Between the channels 13 and the outlet chamber 11 there is a drain device 15 with a central opening 16 and several peripheral openings 1LI 17, the diameter of which is larger than the diameter of the central opening and which allow the entire separated more severe closed phase to pass under normal operating conditions. Drainage device 15 may be a removable disk, which allows you to quickly change the size and radial position of the drain holes.
    The separator is provided with an inlet 18 for supplying an additional heavy phase and a valve 19 for alternately feeding the mixture being processed and an additional heavy phase into the separation chamber.
    The separator works as follows.
    The processed mixture is fed through the inlet pipe 1 into the separation chamber 9 and during the separation, the interface of the Phases takes the position AA (Fig. 1). The holes 17 in the drainage device 15 for withdrawing the heavy phase are sufficient to discharge all of the separated heavy phase to the separator. Before the release of psham through the opening 2 begins, an additional volume of the heavy phase is introduced by switching the valve 19, by virtue of which the supply of the processed mixture is stopped and the inlet 18 is opened to supply the additional heavy phase.
    Next, begin the operation of release. In this case, the interface of the phases takes the position of the BB (Fig. 2) and the surface. phase separation does not reach the overflow side 20.
    In the centrifugal separator can also be used disk.
    the holes 21 and the central hole 22 correspond to the holes 17 and the internal drain device 15
    (Fig. 1).
    As soon as the volume of fluid — the sludge ejected during each discharge — becomes large enough so that the radius of the interface between the light and heavy phases becomes equal to
    0 or more than the outer diameter of the upper disk, the liquid phase flows through the channel 13 into the outlet chamber 11.
    Consequently, due to the limited amount of additional filing
    The 5th heavy phase, equipping the separator with an overflow side located between the separation chamber and the discharge chamber for the light phase, as well as equipping the separator with a disk with holes creates conditions under which the hard phase never enters the bijnycKHoe light phase hole and a certain layer of light phase always remains inside the chamber
    5 separation, regardless of the volume of the additional heavy phase, which, in turn, reduces the loss of the light liquid phase.
