Definitions
- the invention relates to a refiner for comminuting fibrous materials grinding surfaces arranged on a rotor and a stator, the one form a cylindrical or conical grinding gap.
- the refiner according to the invention is therefore characterized in that the setting of the grinding gap on the stator and on the rotor provided, mutually displaceable wedges. This will an axial movement, which is the same size over the circumference, into a corresponding radial movement converted. By this principle the exact same position of the knives is guaranteed.
- An advantageous development of the invention is characterized in that that an axially displaceable wedge carrier is provided.
- a favorable further development of the invention is characterized in that that a radially displaceable wedge carrier is provided. Through this Wedge carrier allows the corresponding axial movement in a radial Convert movement, and thus adjust 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 allows an optimal adjustment of the grinding gap to the Properties of the fiber 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 or when larger ones suddenly appear Particles to avoid damage to the grinding plates.
- a favorable further development of the invention is characterized in that that the relative speed on the circumference 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 carrier two wedges are provided, the oblique Areas on corresponding surfaces of the radially displaceable Wedge carrier slide.
- An advantageous embodiment of the invention is characterized in that that the radially displaceable wedge carrier is divided into circular segments.
- FIG. 1 shows a variant of the invention
- Fig. 2 shows a variant with cone refiner
- Fig. 3 shows a variant with double cylinder refiner
- Fig. 4 shows another variant with double cylinder refiner
- Fig. 7 and 8 variants with sliding 9 a side view
- FIG. 10 a section through a cylinder refiner
- FIG. 11 a double cylinder refiner with a central material feed
- FIG. 12 a double cylinder refiner with a central material feed
- FIG. 13 a further variant with a central material feed.
- Fig. 1 shows schematically the adjustment mechanism in a refiner Single cylinder. It consists of an axially displaceable wedge carrier 1 and a radially displaceable wedge carrier 2, on which there is a grinding plate 5 is located. The counter grinding plate 5 'is located on the rotor 4. Die Power transmission of the adjustment mechanism takes place along an inclined Level. If the wedge carrier 1 is now axially displaced, it results from the power transmission on the wedge a radial displacement of the wedge carrier 2. This allows the gap 3 between the grinding plates 5 and 5 'to be precise can be set.
- Fig. 2 shows an analog variant, with the rotor 4 as a cone rotor is trained. Accordingly, the grinding plates 5 and 5 'as Parts of a cone executed.
- Fig. 3 now shows a variant with a double cylinder refiner.
- a force on the axial displacement of the wedge carrier 1 Wedge carrier 2 applied which thereby moved in the radial direction becomes.
- the grinding gap in the Operation is between 0 and 2 mm, for example 0.5 mm. in the In the event of major contamination or when starting up
- the machine can open the gap up to 15 mm.
- Fig. 4 shows a further variant of the employment with one Double cylinder refiner.
- one elongated wedge here are two shorter wedges, each approximately the length of one of the cylindrical ones Correspond to grinding surfaces 5 ', attached to the wedge carrier 1.
- the wedge carrier 2 in the area of these two cylindrical grinding surfaces 5 'inclined planes on which the wedge carrier 1 slides along.
- the Operation is the same as in the previous variants, by moving the wedge carrier 1 in the axial direction as well the wedge carrier 2 is displaced in the radial direction.
- Through the Splitting into two wedge surfaces is a better and more even one Power transmission and thus a much more precise setting of the Grinding gap 3 between the grinding plates 5 and 5 'possible.
- FIG 5 and 6 show analogous configurations, with FIG from the center to the outside tapering cone rotor and in Fig. 6 conical rotor that widens outwards from the center become.
- Fig. 7 shows a variant, the two on inclined planes wedge carriers running against each other are combined 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 on the rotor located grinding plates 9 'carries.
- the stator 10 with the counter grinding plates 9 remains constant, whereby between the grinding plates 9 and 9 ' the grinding gap 8 is set.
- Fig. 8 shows another variant of the embodiment of FIG. 7, 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 bolts 11 can be seen, with the aid of which the wedge carrier 1 is axially displaced.
- the displacement bolts 11 are driven by a motor 13, the force of which is redirected by means of gears 12.
- gear 12 is also a smooth adjustment of the Shift pin 11 reached.
- the inlet 14 for the Fibrous suspension recognizable.
- FIG. 10 shows a possible section through a rotor. It's the one here axially displaceable wedge carrier 1, the radially displaceable wedge carrier 2, the formed by the grinding plates 5 and 5 'grinding gap 3 and the rotor 4th recognizable.
- the radially displaceable wedge carrier 2 slides on the inclined plane 15 between wedge carrier 1 and wedge carrier 2 and will along the edges of the triangular brackets 16 radially postponed.
- FIG. 11 shows a possible fabric guide of a double cylinder refiner, the fabric being fed through nozzles 14 and 14 'and being removed again centrally through the nozzle 18.
- the material is deflected on both sides by a disk 19 to the material feed channel and from there enters the grinding gap 3.
- the same fabric guide is also possible with a double cone, which can be provided as an either expanding or tapering cone from the outer inlet to the central outlet.
- FIG. 12 shows a possible material guide of a double cylinder refiner with the grinding gap adjustment according to the invention, the material being fed centrally through the material feed 14 ′ and being discharged again at both ends of the refiner through outlets 18 and 18 ′.
- the variant according to FIG. 4 is shown here, the variant according to FIG. 3 can also be used.
