Definitions

  • the invention relates to a refiner consisting of a rotor and stator with an inlet pipe and a cylindrical or conical grinding gap between rotor and stator.
  • the aim of the invention is therefore to address the disadvantages of the known cylinder and To bypass cone refiners in order to subsequently increase high throughputs enable.
  • the invention is therefore characterized in that the stock feed channel extends from the inlet pipe to the grinding gap in the radial direction.
  • the material supplied is accelerated in the circumferential direction by the rotation of the rotor, which causes an increase in pressure in the liquid. This pressure build-up on the one hand saves the feed pump, on the other hand there is a good rotationally symmetrical flow.
  • An advantageous embodiment of the invention is characterized in that the stock feed channel is rotationally symmetrical. This results in a uniform and rotationally symmetrical flow against the grinding gaps.
  • An advantageous development of the invention is characterized in that that the inlet pipe connected to the stock feed channel has an axis has, which coincides with the axis of the rotor. In this way the fabric is fed directly into the axis of the refiner, causing the fabric on the one hand, already partially in the tube before entering the stock feed channel is accelerated and on the other hand an even distribution of the substance is effected.
  • a favorable further development of the invention is characterized in that that a disc is provided between the inlet pipe and grinding gap, the limited the stock feed channel. If the material is fed outside of the Axis, the pulley deflects the fabric on the shaft and rotationally symmetrical outwards, here between the disc and Rotor end face accelerating the liquid radially outward takes place and then the liquid in the grinding gap evenly flows in distributed.
  • a favorable embodiment of the invention is characterized in that that a cylindrical rotor is provided. It can also be a Cone rotor expanding the direction of flow of the material or alternatively conical rotor tapering in the direction of flow of the material be provided. Depending on requirements, the suitable form of the Grinding gap can be used.
  • An advantageous development of the invention is characterized in that that a double rotor is provided.
  • a double rotor in which the Rotor both cylindrical and conical (expanding cone or tapered cone) can be a large one Throughput can be achieved, also a uniform rotationally symmetrical flow to the grinding gaps takes place.
  • a favorable further development of the invention is characterized in that that the stock feed channel is arranged between the two rotors. Especially when using an inlet pipe that is in the axis of a The fabric can be fed into the center of the refiner and there through the rotation to the outside, resulting in a leads to a corresponding rise in pressure. The fabric then becomes centered inserted into the corresponding grinding gap, whereby another Uniformization of the feed is achieved.
  • An advantageous embodiment of the invention is characterized in that that a cylindrical and a conical grinding gap are lined up are.
  • the series of a cylindrical and a conical Grinding gap can either be on a rotor or using two successive different rotors can be achieved. In both cases the sequence of the sequence is arbitrary and only depends on the material properties to be achieved.
  • a favorable further development of the invention is characterized in that that internals in the stock feed channel and / or inlet pipe, in particular Blades, are arranged. Through such installations in the inlet pipe or in the stock feed channel, the acceleration of the liquid can also increase the effects of wall friction are significantly increased.

  • Fig. 9 shows a variant with an axial Feed and double rotor consisting of cylinder and cone rotor
  • FIG. 14 shows a section along line A-A in FIG. 5 represents.
  • FIG. 1 shows a refiner according to the invention with inlet 1, Fabric feed channel 7, grinding zone 3, outlet 4, rotor 5 and stator 6.
  • the fabric flows here through the inlet 1, which is arranged in the axis of the rotor 5 is central to the refiner.
  • In the acceleration zone 7 between the rotor 5 and housing 6 is made by wall friction or by special internals (see Fig. 14) an acceleration of the material in the circumferential direction and thereby the pressure build-up. Then the fabric flows through the Grinding zone 3 and leaves the refiner through the outlet 4.
  • the housing 6 consists here of an axially displaceable ring on which a wedge 10 is attached.
  • the grinding plates are with another wedge 11 connected, a setting by the displacement of the ring 9 the grinding gap 3 takes place.
  • Fig. 2 shows an analog refiner, the feed here done laterally.
  • the fabric flows through the one on the side Inlet 1 in the refiner and through a disc 8 to the shaft redirected. There it is caused by wall friction or by special Built-in accelerates and enters the stock feed channel 7 between Disc 8 and rotor 5, channel 7 acting as an acceleration zone. In this acceleration zone there is a further acceleration in Circumferential direction and thus the required pressure build-up.
  • the Pressure build-up is in the range of 1.5 to 2 bar.
  • the material flows through the grinding zone 3 and leaves the Refiner through outlet 4 opposite inlet 1. Also here the grinding gap 3 is adjusted by the sliding arranged wedges 10 and 11.
  • Fig. 3 and Fig. 4 show analog refiners to Fig. 2, with the same 3 is a conical refiner with an expanding Cone cone and in Fig. 4 a conical or cone refiner with one tapered cone is shown.
  • the fabric flows through the as Hollow shaft formed inlet 1 through the rotor 5 in the middle arranged fabric feed channel 2.
  • the pressure builds up.
  • the grinding gap 23 is adjusted also here again by means of an axially displaceable ring 9 the possibility of a wedge 10 acting over the entire length or with the grinding plates connected counterpart 11 is here in wedge 10a and wedge 10b split wedge 10 shown.
  • the counterpart 11 has corresponding wedge-shaped surfaces. This is a better and more even force distribution can be achieved.
  • FIG. 6 and 7 represent a refiner constructed analogously to FIG. 5 Double cone, the cone shape from the stock feed channel 2 seen to the outlet 4a or 4b widens in Fig. 6 and in Fig. 7th is tapered.
  • the mode of operation corresponds to the function of that shown in FIG. 5 Double cylinder refiner.
  • FIG. 8 A further possibility is the embodiment according to FIG. 8, wherein here the fabric on both sides through the inlet 1a or 1b towards the shaft fed and deflected through the disc 8 into the stock feed channel 7 becomes. From there, the material enters the grinding gap 3 on both sides and becomes central discharged through the outlet 4.
  • the same fabric guide is also with one Double cone possible, this from the outer inlet to the center Outlet as an either expanding or tapering cone can be provided.
  • FIG. 9 shows the example of a refiner with a double rotor and as a hollow shaft trained axial inlet 1 the combination of cylindrical and conical grinding zones.
  • the Inflow also on both sides through an inlet with a deflection done by a disc and the outlet be arranged centrally.
  • FIG. 10 to 13 represent the combination of cylindrical and conical grinding zones on a rotor.
  • the flow can either first through the cylinder (Fig. 11, Fig. 12) or first through a cone part (Fig. 10, Fig. 13), the cone either expanding (Fig. 10, Fig. 12) or tapering (Fig. 11, Fig. 13) is.
  • the definition of widening or tapering for the cone is always made in the direction of flow of the substance.
  • Fig. 14 shows a section along line A-A in Fig. 5.
  • Internals 12 which are also referred to as blades or wings can. These internals 12 divide the stock feed channel 2 into individual ones Stock feed channels 2 'through which the pulp suspension from central inlet 1 is led to the outside grinding gap 3. By these internals 12, here as wedges made of full material are trained, the stock suspension is additionally accelerated and it there is an increase in pressure.
  • the internals 12 can also be hollow be or rounded on its surface, i.e. Shovel-shaped his.
  • Such internals 12 can also in the fabric channel 7 e.g. the 1 - 4, or 8, 10 - 13 as well as the Fig. 5 analog versions of Figs. 6, 7 and 9 are used.
