Definitions

  • the invention relates to a self-emptying separator for the centrifugal separation of a suspension S into at least one light liquid phase LP, one heavy solid phase SP and one medium-heavy intermediate phase IP, which has a centrifugal drum rotatable about a rotational axis D according to the preamble of claim 1 and a method according to claim 17.
  • discontinuous self-draining separators In addition to one or more continuous outlets for one or more liquid phases, generic discontinuous self-draining separators have a discharge system with a piston valve that can be moved alternately into an open and a closed position by a fluid, particularly with liquid as the fluid.
  • the piston valve opens (open position) and closes (closed position) one or more solids discharge openings in the drum wall. In the open position, a solid phase is ejected from the centrifugal drum and thus removed from the drum. In the closed position, the solids discharge openings are closed, preventing this from happening.
  • an incoming suspension is separated in the drum into a lighter or less dense liquid phase, a medium-heavy or medium-dense intermediate phase that is usually still flowable, and a heavier (possibly also still flowable) or denser solid phase.
  • the light phase is the least dense phase
  • the medium-heavy phase is a phase with a relatively higher density
  • the heavy phase is one with an even higher density.
  • the mechanically acting opening and closing means of the first discharge device is a piston slide arranged in or on the outside of the centrifugal drum, in particular a hydraulically controllable piston slide, which can be moved into different positions in order to open the one or more solids discharge openings in an open position or to close them in a closed position.
  • the mechanically acting opening and closing means of the first discharge device has at least one or more electrically or fluidically controllable valves, in particular piston valves, which are assigned to the respective solids discharge opening(s) in order to open them or to close them in a closed position.
  • the mechanically acting opening and closing means of the second discharge device is a piston slide which is arranged on the outside of the centrifugal drum and is in particular hydraulically controllable and which can be moved into different positions in order to open the one or more discharge openings for the intermediate phase IP in an open position or to close them in a closed position, or it can be provided that the mechanically acting opening and closing means of the second discharge device has at least one or more electrically or fluidically controllable valves, in particular piston valves, which are assigned to the respective discharge opening(s) for the intermediate phase IP in order to open them or to close them in a closed position.
  • the mechanically acting opening and closing means of the first discharge device is a piston slide arranged in the centrifugal drum, in particular a hydraulically controllable piston valve
  • the mechanically acting opening and closing means of the second discharge device is at least one controllable piston valve which is assigned to the respective discharge openings for the intermediate phase IP in order to open them or to close them in a closed position.
  • the mechanically acting opening and closing means of the first discharge device has controllable piston valves which are assigned to the respective solids discharge openings in order to open them or to close them in a closed position
  • the mechanically acting opening and closing means of the second discharge device has controllable piston valves which are assigned to the respective discharge openings for the intermediate phase IP in order to open them or to close them in a closed position.
  • radius R3 is smaller than radius R2, where the solid discharge openings are located, but larger than radius R1, where the liquid phase LP is discharged. This advantageously results in a defined discharge of each phase, largely eliminating mixing with the other phases.
  • a paring disc can be assigned to the liquid discharge.
  • the liquid discharge can also be implemented in other ways.
  • the discharged solid phase SP is expelled through the at least one solid discharge opening into a first annular space serving as a solids catcher.
  • the first annular space is arranged in a hood-like housing and has a nozzle arranged radially on the first annular space for connecting a hose or a line for further discharge of the solid phase SP.
  • the discharged intermediate phase IP passes through the at least one discharge opening into a further annular space arranged in the hood-like housing and having a nozzle arranged radially on the further annular space for connecting a hose or a line for further discharge of the intermediate phase IP.
  • the light liquid phase LP which flows radially inward from the disc pack 7, flows into a paring disc chamber 10, which rotates with the centrifugal drum 1.
  • a paring disc 11 is arranged in the paring disc chamber 10. This paring disc 11 is non-rotatable in the paring disc chamber 10, i.e., is arranged stationary.
  • the paring disc 11 - also referred to as a gripper - which operates as a centripetal pump
  • the liquid phase LP is diverted from the centrifugal field forming in the operating centrifugal drum 1 on a radius R1 and guided or directed out of the centrifugal drum 1 via the liquid discharge 9, the annular space 9', and the nozzle 9".
  • the discharge of the liquid phase LP thus takes place continuously.
  • a fluidically and/or electrically - here fluidically - controllable and mechanically acting opening and closing means is provided, which is designed here as an - inner - piston slide 12 arranged in the centrifugal drum 1.
  • the inner piston valve 12 is provided for opening and closing at least one solids discharge opening 13.
  • several of the solids discharge openings 13 can be circumferentially distributed in the region of the largest diameter—on a radius R2—of the centrifugal drum 1.
  • the discharged solid phase SP passes into a first solids trap-like annular space 14, which is arranged in the housing 2 and can have a nozzle 14' arranged radially on the first annular space 14 for connecting a hose or a line for further discharge of the solid phase SP.
  • a first discharge device 15 For discharging the solid phase SP, a first discharge device 15 is provided, which comprises a mechanically acting opening and closing means that can be fluidically actuated by actuators to carry out opening and closing movements.
  • the first discharge device 15 can comprise an injection chamber 16 for opening fluid and an injection chamber 17 for closing fluid, to which a fluid, in particular water, for activating the opening and closing movements of the inner piston slide 12 can be supplied via an opening fluid supply 18 and a closing fluid supply 19, in which a first opening fluid valve V1 and a first closing fluid valve V2 are arranged.
  • the closing process of the solids discharge openings 13, i.e., in this case, a lifting of the inner piston slide 12, can be achieved by closing fluid, which is injected into a chamber below the inner piston slide 12.
  • the closing fluid is metered via the closing fluid valve V2.
  • the chamber is connected to piston valves 20, which are arranged in the wall of the centrifugal drum 1 in such a way that they can be closed by the centrifugal force prevailing in the centrifugal drum 1 when in operation.
  • the opening process of the solids discharge openings 13, i.e., the lowering of the inner piston slide 12, is achieved by opening fluid, which opens the piston valves 20, which in turn allows the closing fluid below the inner piston slide 12 to escape from the chamber.
  • opening fluid which opens the piston valves 20, which in turn allows the closing fluid below the inner piston slide 12 to escape from the chamber.
  • a small amount of opening fluid is briefly fed through a supply line via an opening fluid injection chamber 16 into connecting lines in the drum base 3.
  • the opening fluid ensures the buildup of all-round fluid pressure, which moves a closing piston against the centrifugal force in a radial direction toward the rotational axis D, thus opening the piston valve 20 of the centrifugal drum 1.
  • the opening fluid is dosed via the opening fluid valve V1.
  • the closing fluid escapes into a second annular space 21, which is arranged in the housing 2 and can have a nozzle 21' arranged radially on the second annular space 21 for connecting a hose or a line for further discharge of the fluid.
  • the outer, second piston valve 22 is arranged below the centrifugal drum 1 on its outer side.
  • the piston valve 22 is intended to close or open the discharge openings 25 so that the intermediate phase IP can be discharged from the discharge openings 25.
  • the piston valve 22 is movable in the axial direction.
  • the piston valve 22 is movably guided in a support ring 22'.

  • the intermediate phase IP can be discharged through nozzle-like pipes 23, which are mounted in bores in the inner piston valve 12 distributed around the circumference and whose length is adjusted so that it extends into the layer of the intermediate phase IP that forms during rotation of the centrifugal drum 1, which is characterized here by a radius R3.
  • the intermediate phase IP reaches at least one, preferably several, discharge openings 25 distributed around the circumference of the centrifugal drum 1, which can be closed or opened by the outer piston valve 22.
  • the radius R3 is smaller than a larger radius R2 on which the inlets of the heavy solids discharge openings 13 are arranged, but larger than the radius R1 on which the light liquid phase LP is discharged by the paring disc 11.
  • a discontinuously operating second discharge device 26 is provided, which comprises the mechanical opening and closing means, which can be fluidically actuated by actuators to carry out opening and closing movements.

  • the closing fluid escapes through the piston valves 31 into a fourth annular space 34, which is arranged in the housing 2 and can have a nozzle 34' arranged radially on the fourth annular space 34 for connecting a hose or a line for further discharge of the fluid.
  • the actuation of the inner piston slide 12 and the actuation of the outer piston slide 22 can be controlled independently of each other by a control unit (not shown here).

  • the radius R3 is smaller than the radius R2, on which the solids discharge openings 13 are arranged, but larger than the radius R1, on which the liquid phase LP is discharged by the paring disc 11.
