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 known for example from DE-PS 30 47 013.
  • This device which is suitable for dispersing waste paper, is used to process the material intensively mechanically and thermally, as a result of which the impurities contained therein can be detached from the fibers, shredded and / or brought below the visibility limit.
  • the fibrous material is not processed in a pumpable suspension, but in the form of a doughy or crumbly high consistency material, preferably with a dry content between 20 and 40%. In this way, considerably higher shear forces can be transmitted into the fiber material, whereby the stated goals can be achieved without a substantial change in the fiber length.
  • the effect of mechanical treatment is further enhanced by heat, for example by setting a fiber temperature of 90 o Celsius or even higher.
  • the tooth heights that can be realized in the prior art for devices of this type also depend on the production method for the device for the mechanical treatment of highly consistent fibrous material. So there are cast circle segments, which are assembled to form a closed ring-shaped rotor or stator assembly. For casting and molding reasons, e.g. Components manufactured using the sand casting process must not be less than 6 mm wide and 6 mm wide, and the height of the teeth must usually not exceed 30 mm. Devices that are manufactured in such a method can only have a comparatively low material hardness.
  • the other working method is based on closed individual rings into which the gaps have to be milled. These rings are assembled in a concentric arrangement to form a complete rotor or stator set. Because of the milling process, the gaps per se could be smaller than with the casting, but there are restrictions due to the strength requirements. Nevertheless, milled clothing rings with higher teeth can be produced than if they were cast. However, the high manufacturing costs are disadvantageous when milling.
  • the invention is therefore based on the object of providing a device for the mechanical treatment of highly consistent fibrous material, with which it is possible to process a larger throughput than before while maintaining or improving the treatment effect.
  • the flow cross sections between the teeth available to the fibrous material can be enlarged without fear of overloading the tooth bases.
  • the connecting web between adjacent teeth brings about a counter-torque which increases the resistance to bending of the teeth.
  • peak values of shear forces are distributed over several teeth.
  • Fig. 1 shows two mutually movable complementary treatment tools 1 and 2 which are in engagement with each other so that they can cooperate.
  • the treatment tool 1 may belong to a rotor and the treatment tool 2 to a stator.
  • the treatment tool as seen in the direction of flow, is closed radially on the outside with a stator.
  • the radially last ring is a rotor ring, as a result of which, for example, the material would be thrown out of the treatment apparatus.
  • the selected representation in the form of a section in a side view reveals that the teeth 3, 4, 3 ', 4''which belong to different treatment tools alternate radially from the inside out. Their height is given as H or H '.
  • the direction of the material flow, radially from the inside to the outside, is indicated by the arrow S. 2 shows, the arrangement is such that ring-shaped teeth each form a row of teeth and the row of teeth of a treatment tool in each case Empty space 7 (FIG. 2) of the complementary tool is sufficient. Adjacent teeth of the same row of teeth are connected to one another by webs 8, 8 ', the webs having a height of H1 or H1'. The length of the gap remaining between the web 8, 8 ′ and the base body of the treatment tool 1, 2 is indicated by L or L'.
  • FIG. 2 shows a device designed according to the invention in a view from above, the teeth being shown partially cut. Only a part of the existing teeth is shown. It can be seen that the teeth are arranged concentrically in rows of teeth. In the two radially outer rows of teeth, two adjacent teeth 3 ', 4' are connected to one another by webs. It is also well possible to form such webs 8 in a ring shape and thereby connect a larger number of teeth in groups. In extreme cases, the bridge can encompass the teeth of an entire row of teeth. It should be noted that it is not necessary for all rows of teeth to be provided with webs. This measure is particularly advantageous on the radially outer rows of teeth.
  • FIG. 3 For a better illustration of the device, an embodiment is shown in perspective in FIG. 3.
  • the treatment tool 1, which is only partially shown, contains an annular row of teeth with teeth 3 which are connected to one another by the web 8.
  • the bridge lies at the tips of the teeth. This does not have to be the case in all cases.
  • the bridge could also connect the teeth in other places and stabilize them mechanically.
  • the treatment tool 2 cooperating with the treatment tool 1 shown here can in principle be constructed in a similar manner.
  • the side view shown in Fig. 5, schematically in section, shows two treatment tools 1 and 2, which are in engagement so that the intended use of the processing device is possible.
  • the webs can be placed in such a way that they lie radially in the same area in the case of complementary treatment tools, so that the mostly undesired covering effect for the material stream passing through is minimal.
  • the position and shape of such webs should be optimized in terms of strength and treatment technology.
  • the machining edges can run over the entire height H or H 'of the teeth, that is, they can be longer, which is advantageous in many cases when treating the fabric.
  • FIG. 7 shows a treatment machine in which two treatment tools 1, 2 are inserted. are.
  • a housing 11 essentially surrounds this and has a feed opening 12 and a discharge opening 13, through which the fibrous material is to be fed in or out.
  • the machine has a conveyor 14 which compresses the crumbly high-consistency substance, so that a plug is formed.
  • the fibrous material is guided radially outward between the treatment tools 1, 2 (arrow S) and then leaves the housing 11 through the discharge opening 13.
