    A centrifuge with a self-emptying drum including drum jacket having ejection openings for the solids that collect in the solids space. The openings can be blocked off with a piston valve with which is associated a closure compartment that can be charged with closure liquid. The closure compartment has outlet channels around it that can be blocked off with a hydraulically controlled valve body. When the valve is open, the closure liquid flows into a compartment with choked run-off bores. The compartment has sufficient capacity for part of the closure liquid. The compartment has at least one run-off channel that has a valve with a piston that can be shifted hydraulically in it. When the solids space is to be completely emptied, the closure liquid flowing into the compartment moves the valve piston into the opening position so that the closure liquid can flow off through a channel. If the solids space is only to be partly emptied, the valve piston is retained in the sealing position, in which it is charged with pressure liquid on the side facing away from the compartment.

     The invention relates to equipment for the separation of fluid in the field of centrifugal forces.
    A centrifugal separator is known, which contains a drum mounted on a vertical shaft and has a base with outlet openings for sludge, etc., a cover. a plate holder with a plate package, located in the base (a cone-shaped piston and arrangement for moving the latter,: —the two communicating with each other by means of the vertical channels of the chamber for the working fluid, having a base for supplying and discharging the latter; under the cone-shaped piston S of the other — in the axis of the drum., the locking ring piston with seals for closing said vertical channels 5- above which W is located the distribution, separation chamber with throttling holes In this case, the outer surface of the closure ring piston is the inner wall of the working chamber, which is disassembled into the base of the drum, and an additional distribution chamber is mounted to the outer surface of this piston under each vertical channel. working fluid with jBnycKHHMH and exhaust ports tj,
    The purpose of the invention is more complete unloading of the slurry space of the drum and the acceleration of this process. 5 In FIG. 1 schematically shows a separator drum, a longitudinal section; in fig. 2 and 3 - the same options. The centrifugal separator has a bank mounted on a vertical shaft 1 containing a base 2 with outlet holes 3 for sludge, a cover 4, a plate holder 5 with a package of plates 6, a cone-shaped piston 7 located at the base and a device for moving the latter, including two communicating with each other by means of vertical channels 8 chambers 9 and 10 for the working fluid, one of which is located

    The working chamber 16 is a working fluid with inlet 17 and outlet 18 channels. The drum cover 4 is attached to the base by means of a locking ring 19. The drum base is directed towards the 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 through channel 2A is connected to cavity 25,
    The working fluid chamber 10, located at the base of the drum, is provided with at least one additional discharge channel 26, 20 whose cross sectional area is equal to or exceeds the total cross sectional area of the vertical channels that communicate this chamber with the working fluid chamber 9.
    In the additional discharge canap 26, a hydraulic controlled valve is installed containing a valve 27.
    According to the embodiment (Fig. 1), the valve spool 27 of the pacno-i-valve is directed in the direction of the ring 20 below the chamber 10 in such a way that its longitudinal axis is parallel to the axis of rotation of the drum. At the base of the drum there are channels 28 and 29 for supplying the working fluid under the spool 27, which is in the locking position. The valve spool 27 has a calibrated channel 30 located along its axis along the entire length, which connects the lower control chamber 31 with the chamber 10 and through which working fluid can be fed into the chamber 10 to reduce the volume of this chamber.
    In the chamber 31 can also be installed additional similar valve 32 with ca. the channel 33.
    The spool 27 (Fig. 2) of the hydraulically controlled valve may be located radially relative to the axis of rotation of the drum. The valve spool 27 should be lightweight and positioned in such a way. so that it can move in the opening position under the action of the working housing that flows out of the chamber 10.

    The long axis is located radially relative to the axis of rotation of the centrifugal drum. The valve spool 27 is held in the locked position by the centrifugal force generated by the rotation of the drum.
    The centrifugal separator operates in the following manner.
    Before feeding the suspension to the separation, the closure ring piston 11 is in the closed position. In chamber 9, through apertures 34 "cavity 25 and channels 24, the working fluid is supplied, by means of which the cone-shaped piston 7 moves in the closed position. The initial suspension enters the cavity of the plate holder 5 and then into the inter-plate gaps.
    As a result of the separation, the sediment accumulates in cavity 35, after which it is partially discharged. load. In order to accomplish the latter, the working fluid is supplied to the distributing chambers 13 and 16 of the locking ring piston 11 through the openings 36, the cavity 25 and the channels 17 and 22..
    Since the pressure of the fluid in the distribution chamber 13 is significantly greater than that in the distribution chamber 16, the locking ring piston 11 moves in the direction of its opening in such a way that the working fluid flowing from the centrifugal force flows from the chamber 9 through vertical fractions of a second. channels 8 to camera 10.
    In order to completely empty the drum sludge space, the lower control chamber 31 does not fill the working fluid, and the working fluid in chamber 10 moves the spool 27 of the hydraulically controlled valve to the open position and the additional discharge channel 26 becomes open.
    Due to the presence of several spools of a certain size of hydraulically controlled valves, as well as the presence of channels 26, it is not possible to increase the pressure in chamber 10 and therefore the working fluid can completely flow out of chamber 9.
    In the embodiment (Fig. 3), in order to fully discharge the thickened solid phase, the control chamber 31 is filled through the channels 28 and 29 with the working fluid, as a result of which the valve spool 27 moves to

    opening position. After the discharge is completed, the supply of working fluid through the holes 34 and the channels 22 into the chamber 13 is stopped and the pressure in it drops. The working LCD flows out of it through the throttled holes 14. Because of the pressure of the liquid in the chamber. 16 above, the closure ring piston 11 moves to the mashing position.
    As a result, vertical channels 8 cone-shaped piston 7 move to close as soon as in cavity 35 due to the removal of a certain amount of sediment pressure builds up so that the pressure developed in chamber 9 remaining working there: the lid is overcoming it, rc continuous flow of working pressure aa in the chamber 9-eyes quickly reach its full height: rot in what keeps the cone-type ratio 7 in the closed position,
    In the distribution chamber 16, up to the edge of the outlet calycle 18 and the working fluid which is under the action of centrifugal force creates pressurej in the suction zone of which the aerial piston ring 11 moves to the shock position while the counter pressure of the distal pressure in the distribution chamber 13 is lower. The back pressure in it is maintained at
    the same level only if through channel 22. a liquid is supplied to the indicated chamber, which flows out through
    throttling the orifice 14. If the liquid in the distribution chamber 13 does not flow, then the pressure in it decreases.
    The proposed design is centro,
    The bend separator allows the shelf to discharge the slurry space of the drum through time intervals, as a result of which the discharge process is accelerated.
