Definitions

  • the invention relates to a centrifuge, in particular a tubular cone centrifuge, for clarifying liquids and for thickening sludge, the centrifuge drum of which consists of two drum halves and an axially displaceable tube connecting the drum halves, with the centrifugal material being fed axially.
  • the invention has for its object to improve the centrifuge of the type mentioned in such a way that an increase in the solids concentration can be achieved.
  • This design makes it possible to reduce the size of the drum interior while the centrifuge is running, preferably towards the end of the treatment period, and thus to compress the centrifuged material, so that clear liquid or with a very low solids concentration inside into the surface or supply is delivered, which can then be discharged in the usual way. This increases the solids concentration in accordance with the volume reduction.
  • the tube cone centrifuge of Figure 1 consists of two axially separated drum halves 11, 12 which are rotatable with the displacement body 20. Both drum halves are connected by a tube 13, which is closed at one end and is axially displaceable by a double-acting hydraulic cylinder 18. By axially shifting this tube 1 3, the dry centrifugal material in the drum can be thrown off.
  • One drum half 12 is axially displaceable by a hydraulic cylinder 19 from its initial position, which it assumes when the centrifuge drum is filled, against the other, fixed drum half 12, so that the drum interior can be reduced in size.
  • the centrifuged material is fed to one end of the drum interior via a channel 15. After introduction into the interior of the drum, the centrifugal material is subjected to the centrifugal force, so that the solids are deposited radially on the outside and the liquid phase or K lar phase can be discharged via an outlet 16.
  • a filter can be arranged on a displacement body 20 arranged in the interior of the drum, through which the clear phase reaches the outlet 16.
  • the axial displacement of the drum half 12 makes it possible to compress the centrifugal material located radially on the outside, so that it releases clear liquid radially inwards and thereby the solids concentration of the centrifuge located in the interior of the drum guts is increased.
  • the displaceable drum half 12 is expediently designed in such a way that it closes the inlet opening via the displacement body 20 into the centrifuge drum during the adjustment in order to reduce the size of the drum interior, so that in the final phase of operation no centrifugal material gets into the drum.
  • a sieve or filter is expediently arranged on the displacement body 20, at least in the area of the outlet, which, in addition to the filter effect, also has the purpose, after a certain operating time, of causing an increase in pressure in the inlet which can be used for control purposes of the centrifuge.
  • FIG. 2 shows the application of the principle of reducing the drum interior to a double-cone centrifuge or a separator.
  • the centrifuge in turn has two drum halves 11, 12, with a vertical axis, the drum half 12 being displaceable in the usual way with respect to the drum half 11 to open the centrifuge.
  • the drum half 12 has a cylindrical projection 21, in which a piston 22 is slidably arranged to reduce the interior of the drum.
