Definitions

  • the invention relates to a method for separating material to be separated in a centrifugal force separator (ZKS) and a device for carrying out this method.
  • ZKS centrifugal force separator
  • ZKS enable the separation of particles according to their density in relation to the density of a separation medium. Originally developed for coal processing, ZKS are now used for a wide variety of sorting tasks.
  • ZKS typically comprise cylindrical housings, the longitudinal axis of which is usually oriented at an angle, for example between 20° and 40°, to the horizontal during operation.
  • Separating medium is usually introduced through an involute-shaped inlet in the housing jacket in a lower area of the ZKS, so that a turbulent flow with an air core is generated along the longitudinal axis of the ZKS and the separating medium exits again through an involute-shaped outlet in the upper area of the housing jacket.
  • Material to be separated is introduced through an inlet which is usually arranged centrally on an upper end face of the cylindrical housing.
  • Low-density particles float at the interface between the separation medium and the air core and are carried by gravity along the longitudinal axis of the ZKS to an outlet centrally located at the lower rear of the cylindrical housing.
  • the particles contained in the material to be separated can thus be sorted according to their density in relation to the density of the separation medium.
  • ZKS are, among other things, under the designations dense media separator (DMS), cylindrical cyclone separator (cylindrical cyclone separator), dynamic separator (English dynamic separator); or known under the product names Dyna Whirlpool Separator, TriFlo Separator and LAR-CODEMS (large coal dense media separator).
  • DMS dense media separator
  • CMS cylindrical cyclone separator
  • dynamic separator Edinburgh dynamic separator
  • Suitable ZKS are for example in the DE 198 47 229 A1 and in the WO 02/00352 A1 disclosed.
  • One object of the present invention can be seen as alleviating or eliminating at least individual disadvantages of the prior art.
  • An object of the present invention can also be seen as enabling an efficient separation process with high stability and high throughput for different types of material to be separated.
  • An exemplary embodiment of the invention provides a method for separating material to be separated in a centrifugal force separator (ZKS), with a separating medium being introduced into the ZKS in such a way that a vortex with an air core is generated inside the ZKS, with the material to be separated via at least one compulsory conveying device is introduced into the ZKS.
  • ZKS centrifugal force separator
  • Another exemplary embodiment of the invention provides a device for carrying out the method described above, the device having a ZKS with a separation material inlet for introducing separation material and a separation medium inlet for introducing a separation medium, the device having at least one forced conveying device connected to the separation material inlet.
  • the material to be separated is typically introduced solely by gravity.
  • the particles slide, for example, from a funnel into a hose or pipe, which ends in the ZKS.
  • flushing in the material to be separated as a suspension is also known.
  • At least one forced conveying device is connected to the inlet for the material to be separated in such a way that forced conveyance of the material to be separated into the ZKS is made possible.
  • the compulsory conveying device is flanged directly to the separation material inlet of the ZKS.
  • a flange can, for example, be provided with a flat gasket, flexible sealing compound or an O-ring and tightened, whereby a tight connection can be achieved.
  • the compulsory conveying device can be connected to the ZKS, for example, via a sleeve with sealing lips or, if the separation material inlet is designed as a piece of pipe (lining pipe), via an annular space seal or press ring seal.
  • the compulsory conveying device is connected to the inlet for the material to be separated via a compensator. This has the advantage that, for example, shrinkage can be absorbed and compensated for.
  • the forced conveying device can be, for example, a tube in which there is a rotating screw or spiral that ensures the forced conveyance of the material to be separated. It is preferred if the material to be separated is introduced via a screw conveyor or spiral conveyor provided as a compulsory conveying device. According to a preferred embodiment, the compulsory conveying device is therefore a screw conveyor or a spiral conveyor.
  • the introduction via the compulsory conveying device can be regulated, preferably steplessly, via a drive unit.
  • the compulsory conveying device therefore has a drive unit that is preferably infinitely variable. This enables precise material feed control, ensuring high throughput without overloading the ZKS.
  • the separation process can be flexibly adapted to the type of material to be separated by controlling the conveying speed.
  • the compulsory conveying device is therefore preferably driven by a motor whose speed can be infinitely adjusted.
  • the material to be separated is introduced into the compulsory conveying device from a storage container with an agitator.
  • the compulsory conveying device is therefore preferably connected to a reservoir containing an agitator.
  • the agitator allows material bridges to be reduced when loading the compulsory conveyor system, which further increases the efficiency and stability of the input of the material to be separated.
  • the material to be separated is introduced into the compulsory conveying device from a storage container with a discharge floor.
  • the compulsory conveying device is therefore preferably connected to a storage container having a discharge floor.
  • the discharge floor is preferably a moving floor, for example a screw discharge floor.
  • the bottom of the storage tank is at least partially, preferably completely, formed by snails what enables a particularly uniform loading of the compulsory conveying device.
  • the formation of material bridges can be reduced particularly effectively.
  • the flow of separated material can also be varied over a wide range by changing the rotational speed of the screws.
  • the ZKS has an essentially cylindrical housing for accommodating the separating medium and the material to be separated.
  • the ZKS therefore preferably has a housing with a front side and a rear side, which are connected via a substantially cylindrical housing jacket.
  • the front and rear can also be referred to as the cover and base of the ZKS.
  • Particularly preferred are ZKS, as in the DE 198 47 229 A1 and the WO 02/00352 A1 are revealed.
  • the ZKS preferably has at least one inlet for the material to be separated and at least one inlet for the separation medium.

  • low-density material can thus migrate from a separation material inlet at the front through an air column forming along the longitudinal axis of the ZKS to the light material outlet at the rear of the ZKS, where it can be recovered as a light material fraction.
  • the separating medium inlet of the device according to the invention is preferably an involute-shaped inlet on the preferably essentially cylindrical housing jacket of the ZKS. It is favorable if the separating medium inlet is arranged on the housing shell adjacent to the back of the ZKS, in particular if the separating medium inlet is adjacent to the back of the ZKS.
