Definitions

  • the present invention relates to a mixing device for mixing highly viscous media, in particular for a biogas plant according to the features in the preamble of claim 1.
  • Both of these highly viscous media must, on the one hand, be mixed as homogeneously as possible; on the other hand, further processes are necessary, such as filtering, cleaning or sanitizing.
  • the mixing device is characterized in that the agitator is arranged as a vertical screw mixer in the container, wherein the screw mixer has a stirring screw and a sleeve enclosing the stirring screw.
  • a further advantage of the invention provides that the container itself is designed like a silo.
  • a collecting box is arranged below the container or at a lower point of the container.
  • the agitator screw is preferably arranged in the container at an axial distance from the collecting box. Due to the flow within the agitator screw, part of the medium is thus pressed into the collecting box.
  • FIG. 4 a top view of the agitator screw 12 is shown. Here it is shown that there is a lateral step 14 in the radial direction R outwards.
  • clumps are clamped between the inner surface 15 of the sleeve 9 and the agitator screw 12 and shredded.
  • At least part of the medium is pressed into the collecting container 5 during the stirring process or at least partially flows into it.
  • stones 19 bounce off the edge 18 and then also sink to the bottom of the collecting container 5.
  • FIG. 8 shows a further embodiment of the present invention.
  • a screen 28 is arranged below the agitator screw 12.
  • the screen 28 is connected to the agitator screw 12 and rotates with the agitator screw 12.
  • the medium in particular solid bodies or foreign particles, for example stones or glass bodies, are conveyed outwards in the radial direction due to the screen 28 and the associated rotation and then sink down the slope. The separation effect for foreign bodies in the viscous medium is thereby improved.
  • a discharge line 6 is arranged in particular in the axial direction Ax below the screen 28.
  • the upper edge 29 of the opening of the suction line is preferably arranged significantly above the bottom 16 of the collecting container 5, furthermore preferably also above the edge 18 of the lower slope 30 of the container 2.
  • the screen 28 preferably has a diameter that is smaller than the diameter of the agitator screw 12.
  • the diameter of the screen 28 is preferably 20 to 70%, in particular 30 to 60% of the diameter of the agitator screw 12.
