Definitions

  • the invention relates to a paddle wheel for hot, mushy liquids such as e.g. Paddle wheel for aluminum dross or slag or sludge in pelletizing systems.
  • the invention has set itself the task of keeping such formations as low as possible by tearing, so that caking occurs less easily and the movement resistance is thereby reduced.
  • the invention is characterized in that the paddle wheel axially offset and overlapping parts - has at least one scooping part and a stirring part - which are arranged on radial arms and are alternately guided along a circular path and immersed in the hot liquid to be processed.
  • the scooping part and the stirring part are arranged separated from one another by approximately 180 ° with effective areas overlapping in the liquid bath, and preferably cutting on the scooping part and / or on the stirring part are cuts with a breast angle greater than 90 ° and a clearance angle greater than 0 ° with a pulling cut away from the end faces.
  • FIGS. 1 to 5 show the invention in FIGS. 1 to 5, for example and schematically, with a paddle wheel in cross-section in FIG. 1 and an associated elevation in FIG. 2. 3 shows the cutting edge formation of the part immersed in the liquid, FIG. 4 shows a view from direction A in FIG. 1 and FIG. 5 shows a view from direction B in FIG. 1.
  • Fig. 1 the paddle wheel is visible in a cross-section, and you can see the scooping part 1 just immersed in the liquid 3 and the stirring part 2 arranged opposite the axis of rotation 4, which is outside the liquid and after a half turn around the axis of rotation 4 according to arrow 7 in the liquid will dip.
  • the breast angle 5 and also the clearance angle 6 of the dipping edges are shown in FIG. 3, the chest angle 5 being greater than 90 ° and the clearance angle 6 being greater than 0 °.
  • the cutting edges are intended to produce a pulling cut and the solidifying masses are transported away from the contact surfaces of the cutting edges. This can be seen particularly in FIGS. 4 and 5, in each of which a view from the directions A and B is shown with reference to FIG. 1.
