Definitions

  • the invention relates to a refiner for the comminution of fibrous materials, with On a rotor and a stator arranged Mahl vom, the one Form cylindrical or conical Mahlspalt.
  • the inventive refiner is therefore characterized in that the setting of the grinding gap through the stator and the rotor provided, mutually displaceable wedges takes place. This will an axial movement that is the same size over the circumference, in a converted corresponding radial movement. By this principle is ensures the exact same employment of the knife.
  • An advantageous development of the invention is characterized in that in that in that an axially displaceable wedge carrier is provided.
  • a favorable development of the invention is characterized in that a radially displaceable wedge carrier is provided. Through this Wedge carrier can be the corresponding axial movement in a radial Convert movement, and thus set the grinding gap exactly.
  • a favorable embodiment of the invention is characterized in that that the gap is continuously between 0 and 2 mm, preferably between 0 and 1 mm, for example, between 0 and 0.5 mm, is adjustable. This can always be an optimal adjustment of the grinding gap to the Properties of the pulp suspensions take place.
  • An advantageous embodiment of the invention is characterized in that that the gap can be adjusted up to 15 mm. It will also possible during start-up operation or in case of suddenly occurring larger ones Particles to avoid damage to the grinding plates.
  • a favorable development of the invention is characterized in that that the relative velocity at the periphery 15-35 m / sec, preferably 20-30 m / sec.
  • a favorable embodiment of the invention is characterized in that that the speed of the rotor between 400 and 1,800 rpm, preferably between 500 and 1,000 rpm.
  • a double rotor is characterized in that the axial slidable wedge support two wedges are provided, whose oblique Surfaces on corresponding surfaces of the radially displaceable Sliding wedge carrier.
  • An advantageous embodiment of the invention is characterized in that that the radially displaceable wedge carrier is divided into circle segments.
  • FIG. 2 shows a variant with conical refiner
  • FIG. 3 shows a variant with double cylindrical refiner
  • FIG. 4 shows another variant with double cylindrical refiner
  • FIGS. 7 and 8 variants with displaceable 9 shows a side view
  • FIG. 10 shows a section through a cylindrical refiner
  • FIG. 11 shows a double cylindrical refiner with central substance removal
  • FIG. 12 shows a double cylindrical refiner with central material supply
  • FIG. 13 represents a further variant with central material supply.
  • Fig. 1 shows schematically the adjusting mechanism in a refiner with Simply cylinder. It consists of an axially displaceable wedge carrier. 1 and a radially displaceable wedge carrier 2, on which a grinding plate 5 is located. The symbolsmahlplatte 5 'is located on the rotor 4. Die Power transmission of the adjusting mechanism takes place along a leaning Level. Now, if the wedge support 1 is moved axially, it is clear the power transmission on the wedge a radial displacement of the wedge carrier. 2 Thereby, the gap 3 between the refining plates 5 and 5 'exactly be set.
  • Fig. 2 shows an analog variant, in which case the rotor 4 as a tapered rotor is trained. Accordingly, the refining plates 5 and 5 'as Parts of a cone running.
  • Fig. 4 shows a further variant of the employment at a Doppelzylinderrefiner.
  • an elongated wedge here are two shorter wedges, each about the length of one of the cylindrical Grinding surfaces 5 'correspond, attached to the wedge carrier 1.
  • the wedge carrier 2 in the region of these two cylindrical grinding surfaces 5 'inclined planes on which the wedge carrier 1 slides along.
  • the Operation is the same as the previous variants, whereby by displacement of the wedge carrier 1 in the axial direction as well a displacement of the wedge carrier 2 takes place in the radial direction.
  • the Splitting on two wedge surfaces is a better and more consistent Power transmission and thus a much more accurate adjustment of the Mahlspalts 3 between the grinding plates 5 and 5 'possible.
  • Fig. 5 and 6 show analogous embodiments, wherein in Fig. 5 is a from the center outwardly tapered conical rotor and in Fig. 6 a inserted from the center outwardly widening tapered rotor become.
  • Fig. 7 shows a variant, wherein the two inclined planes against each other running wedge carrier are summarized in the rotor.
  • an axially displaceable wedge carrier 6 is provided, which on a Wedge carrier 7 acts, which is adjustable in the radial direction and the rotor located grinding plates 9 'carries.
  • the stator 10 with the counter-grinding plates 9 remains constant, wherein between the refining plates 9 and 9 ' the grinding gap 8 is set.
  • Fig. 8 shows another variant of the embodiment of FIG. 7, wherein the Grinding plates 9 and 9 'form a conical grinding gap 8.
  • Fig. 9 shows a view of a refiner according to the invention, wherein here two sliding bolt 11 can be seen, with the help of the wedge carrier. 1 is moved axially.
  • the drive of the sliding bolt 11 takes place a motor 13 whose power is deflected by means of gears 12.
  • This transmission 12 will also have a uniform adjustment of Sliding bolt 11 reached.
  • the inlet 14 for the Pulp suspension is recognizable.
  • Fig. 10 shows a possible section through a rotor. It is here axially displaceable wedge carrier 1, the radially displaceable wedge carrier 2, the through the refining plates 5 and 5 'formed Mahlspalt 3 and the rotor 4th recognizable.
  • the radially displaceable wedge carrier 2 slides on the oblique plane 15 between wedge carrier 1 and wedge carrier 2 along and becomes along the edges of the triangular brackets 16 radially postponed.
  • FIG. 11 shows a possible fabric guide of a double-cylinder refiner, wherein the material is supplied through nozzles 14 and 14 'and removed again centrally through the nozzle 18. The material is deflected on both sides by a disk 19 to the material supply channel and enters from there into the refining gap 3.
  • the same material guide is also possible with a double cone, which may be provided from the outer inlet to the central outlet as an either widening or tapering cone.
  • FIG. 12 shows a possible material guide of a double cylinder refiner with the grinding gap adjustment according to the invention, wherein the material is fed centrally through the material supply 14 'and discharged again at both ends of the refiner through outlets 18 and 18'.
  • FIG. 4 it can also be the variant of FIG. 3 are used.
  • Fig. 13 shows a further variant, in which case a combination of cylindrical and conical grinding zones is made.
  • the Other elements correspond to those of FIG. 12.
