     one
    The invention relates to equipment for the separation of liquids in the field of centrifugal forces.
    The purpose of the invention is to accelerate the movement of the cone-shaped piston to close the outlet openings and to accelerate the discharge of sediment.
    The drawing schematically shows a part of a separator drum with a longitudinal section.
    The centrifugal separator includes a drum mounted on a vertical shaft 1, containing a base 2 with outlets 3 for sludge, a cap 4, a plate holder 5 with a stack of plates 6, a cone-shaped piston 7 placed at the base and a device for moving the latter, including two communicating with each other using the vertical channels 8 of the chamber 9 10 for the working fluid, one of which is located under the conical piston and the other at the base of the drum, and the locking ring piston 11 with seals 12 for closing the decree nnyh vertical channels over which the distribution chamber 13 is located with throttling apertures 14.
    The outer surface of the locking ring piston 11 is the inner wall of the working fluid chamber 10 located at the base of the drum, while a disk 15 is attached to the outer surface of this piston under each vertical channel to accommodate the seal 12,
    At the base 2 under the piston 11 there is an additional distribution chamber 16 of the working fluid with inlet 17 and outlet 18 channels. Krshka 4 drum attached to the base 2 by means of a locking ring 19 (not shown). The base of the drum has a guide ring 20, which is rigidly connected to its lower part with screws.
    The chamber 10 has throttled outlets 21.
    The distribution chambers 13 and 16 are hermetically separated from the distribution chamber 10 and communicated with the channels 22 and 23 for the working fluid.

    The distribution chamber 9 is connected through channel 24 with cavity 25.
    The separator works as follows.
    5 Before applying the slurry to the separation, the rotary annular piston 11 is in the closed position. The chamber 9 through the openings 26 of the cavity 25 and the channels 24 is supplied with the working fluid, by means of which the cone-shaped piston 7 is moved to the closed position. The initial suspension enters the cavity of the plate holders 5 and then into the inter-plate gaps.
    As a result of separation, the sediment accumulates in cavity 27, after which it is partially discharged. To accomplish the latter, the working fluid is supplied to the distribution chambers 13 and 16 of the locking ring piston 11 through the openings 28, the cavity 25 and the channels 17 and 22. Since the pressure of the liquid
    25 in the distribution chamber 13
    Much more than in the distribution chamber 16, the locking ring piston 11 moves in the direction of the opening position so that the working fluid, under the action of centrifugal force, flows from the chamber 9 through the vertical channels 8 into the chamber 10 in a fraction of a second.
    After filling this chamber, the working fluid closes the vertical channels 8. The cone-shaped piston 7 thus moves to the closed position as soon as in the cavity
    , Q 29 due to the removal of a certain amount of sediment, the pressure will drop so much that the pressure developed in chamber 9 by the remaining working fluid there will overcome it.
    g. With continued supply of working fluid, its division in chamber 9 very quickly reaches its full value, which keeps the cone-shaped piston 7 in the closed position of the cover.
    When the sediment is partially unloaded, the feed of the initial suspension does not stop and after closing the outlet openings 3 the pressure inside the drum
    jr increases again.
    After unloading sediment at the termination of the supply of working fluid through,. holes 28 and channels 22 in the chamber
