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 40%. 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 tooth heights that can be realized in the prior art for such devices depend also of the manufacturing process for the device for mechanical treatment of highly consistent fiber. So there are cast circle segments, which by Stringing together to form a closed ring-shaped rotor or stator set be assembled. For casting and molding reasons, such e.g. Components manufactured using the sand casting process have a gap width of 6 mm and a The tooth width should not be less than 6 mm, and the tooth height is usually not allowed be higher than 30 mm. Devices manufactured in such a process can only have a comparatively low material hardness. The other The working method is based on closed individual rings into which the column is milled Need to become.
- the invention is therefore based on the object of a device for mechanical Treatment of high consistency pulp with which it is possible to create a greater throughput than before to be processed while maintaining or Improvement of the treatment effect.
- the treatment tool 1 can be a rotor and the treatment tool 2 belong to a stator. So in the case shown here it will be Treatment tool, seen in the direction of flow, radially outside with a stator completed. It is easily conceivable that the radially last ring is a rotor ring which is e.g. the substance would be thrown out of the treatment apparatus.
- 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 3, 4, 3 ', 4' '. Their height is given as H or H '.
- Fig. 2 shows the arrangement is such that ring-shaped teeth are each one Form row of teeth and the row of teeth of a treatment tool in each Empty space 7 (FIG. 2) of the complementary tool is sufficient.
- Teeth of the same row of teeth connected by webs 8, 8 ' the webs have a height of H1 or H1 '.
- the between web 8, 8 'and the base of the Treatment tool 1, 2 remaining length of the gap is indicated with L or L'.
- FIG. 2 shows a device designed according to the invention in a view from above, the teeth are shown partially cut. Only part of the in itself existing teeth is shown. One can see that the teeth in rows of teeth are arranged concentrically. There are two in each of the two radially outer rows of teeth Adjacent teeth 3 ', 4' connected to one another by webs. It is also possible to design such webs 8 in a ring shape and thereby a larger number in groups of teeth to connect. In extreme cases, the bar can hold the teeth of an entire row of teeth include. It should be noted that not all rows of teeth with ridges are necessarily must be provided. This measure is particularly advantageous on the radially outside lying rows of teeth.
- FIG. 3 An exemplary embodiment is shown in FIG. 3 for better clarification of the device drawn in perspective.
- the treatment tool 1 shown only partially contains an annular row of teeth with teeth 3, which are interconnected by the web 8 are connected.
- the bridge lies at the tips of the teeth. But that doesn't have to be the case in all cases. So the bridge could also have teeth in other places connect and stabilize them mechanically.
- FIG. 4 and 5 The one working with the treatment tool 1 shown here
- treatment tool 2 can be constructed similarly.
- you can Place webs so that they are radially in the same with complementary treatment tools Range, so that the most undesirable masking effect for the penetrating Material flow is minimal.
- the location and shape of such webs are strength and to optimize treatment technology.
- Fig. 6 shows a variant in which the webs 8 and 8 'do not extend over the entire width B. or B 'extend.
- the processing edges over the entire height H or H 'of the teeth run, so be longer, which is an advantage in many cases Is fabric treatment.
- a housing 11 essentially surrounds it and has one Supply opening 12 and a discharge opening 13 through which the fibrous material feeds or is to be dissipated.
- the machine has a conveyor device 14 at the feed opening 12, which squeezes the crumbly high consistency substance so that a plug arises.
- the fibrous material is moved radially between the treatment tools 1, 2 guided outside (arrow S) and then leaves the housing 11 through the discharge opening 13.
