Definitions

  • the invention relates to a device for the mechanical treatment of highly consistent fibrous material according to the preamble of claim 1.
  • Such a treatment device is for example from DE-PS 30 47 013 known.
  • This device which is suitable for dispersing waste paper, serves the purpose of Machining material intensively mechanically and thermally, which means that the contained therein Contaminants detached from the fibers, crushed and / or below the visibility limit can be brought.
  • the pulp is not in a pumpable suspension processed, but in the form of a doughy or crumbly high consistency substance, preferably with a dry content between 20 and 35%. Let it this way significantly higher shear forces are transferred to the pulp, causing the mentioned goals are achievable without a significant change in Fiber length is done.
  • the effect of mechanical treatment further intensified by heat, e.g. by setting a fiber temperature of 90 ° Celsius or above.
  • the Dispersion After the highly consistent fiber material has passed the processing area, i.e. the Dispersion has occurred, it emerges at the last stage of the stator set. Here it is pushed out by the following substance and essentially leads one radial movement. Because the set contains circular rows of teeth, this is done the ejection of the fiber over the entire circumference, i.e. 360 °. As a rule, that is The central axis of such a dispersing device is arranged horizontally, i.e. of the The pulp is transported in a vertical plane. Where the tooth gaps between the teeth, the fabric falls out freely, e.g. in a vessel, in which, if desired, can be diluted with water.
  • the object of the invention is therefore to provide a treatment device create with which it is possible to discharge processed pulp with simple Means to improve.
  • the subject of the invention also has the advantage of being relatively inexpensive Wear behavior. It is about reducing the wear and tear is known not to be entirely avoided in such devices. The fact that the Substance is removed relatively quickly, caking, which the Favor wear, be prevented. It is particularly advantageous if the Radial projections belong to the part of the treatment tool that is due to the unavoidable wear and tear should be replaced at certain intervals anyway got to. In this way, the normal wear and tear on a few parts limited, while the other machine parts, especially the mounting plates for the trimmings, subject to very little wear.
  • the radial projection can extend over the entire circumference be an annular collar. Like the set, it can do one thing wear-resistant material and, if necessary, together with the set be replaced.
  • FIG. 1 shows two complementary treatment tools that can be moved relative to one another 1 and 2, which are in engagement with each other so that they can cooperate.
  • the selected representation in the form of a section in side view shows that radially from the inside to those belonging to different treatment tools Alternate teeth 4, 3, 4 ', 3', 4 '', 3 ''.
  • the arrangement is such that the row of teeth a treatment tool in each of the intermediate space 11 (Fig. 3) complementary tool is sufficient and a distance a to the teeth of the takes complementary treatment tool.
  • the one on the left belongs here Treatment tool 1 to the stator 6 and treatment tool 2 to the right on the rotor 5.
  • the axis of rotation, not shown, is horizontal here, and the The radial transport direction of the fibrous material lies in vertical planes.
  • the last Row of teeth with 3 '' teeth belongs to the stator set.
  • the treatment tools are housed in a housing 6 ', the stator set with the housing rotatably connected is.
  • Such sets are basically already known and are used, for example De-sticking or dispersing used.
  • the decisive innovation can be found in the Area of the discharge device 8. This shows in the example shown here fixed deflection element 9 with a contour 10, the shape of which is radial emerging fiber material is deflected in the axial direction. It works together with one Number of radial projections 7 (only one drawn), which are about the projection b extend beyond the outermost edge of the rotor 5.
  • Fig. 2 shows a view radially from the outside of a radial projection 7, each in Has the surface A or A 'circumferential direction. You can see some of the outermost teeth 4 '', which starts from the treatment tool 2 axially in the direction of not drawn complementary tool.
  • Radial projections 7 are available, which are each at a distance of 120 ° from one another.
  • the appropriate number of radial projections depends of course Conditions, e.g. Set diameter and speed from. They run over one Circumferential extent c, which is about 10 ° here.
  • the run-up angle ⁇ between the Radius and the areas A, A ' is approximately 20 °.
  • FIG. 4 shows the top view of a stator set with teeth 3, 3 ', 3' 'between which are the spaces 11 and also the contour 10 of the Deflection element 9.
  • the embodiment shown here is part of a Device according to the invention, the axis of rotation of which is horizontal. The view this figure is to be understood so that the direction according to arrow 12 is above. Because of the conditions already described, especially in the upper area of the Treatment device, the deflection element 9 is attached there. It stretches here over a circumferential angle of approx. 270 °. There are variations of this circumferential angle can be determined by experiments. In other cases where the axis of rotation is vertical, the deflecting element is essentially on the entire circumference to provide.
  • contour 10 in contact with the material Deflection element 9.
  • the contour 10 is part of a Torus'T educated.
  • other forms are also conceivable with which the deflection takes place can.
