Definitions
- the invention relates to a method for dispersing paper pulp according to the Preamble of claim 1.
- Procedure of the above Be e.g. used to improve the quality of fiber, which was obtained from waste paper. It is known that pulp by Dispersing can be homogenized and thereby significantly improved. This will a high-consistency fiber fabric that has a dry content between 15 and 35%. In many cases it is dispersed at a temperature that is well above the ambient temperature. Disperger sets with which processes of this type are compact and have an excellent dispersing effect. However, they require an even material flow. Since the dwell time of the Substance between them is very short, irregularities cannot be balanced. The result would be an uneven dispersion.
- a particularly economical machine for thickening is the screw press.
- the fiber suspension is between a screw conveyor and a perforated jacket surrounding it, wherein the water comes out through the holes in the jacket.
- the resulting compact or Grafting is squeezed out of the snail and breaks into pieces. The sections are relatively large and therefore lead to an uneven flow subsequent apparatus.
- a dispersing device in which the from a Screws originating from the screw press are fed directly. He is in one Shredding tool with scrapers or knives, which are in the Disperger inflow are.
- the invention used drumstick takes the compressed by the squeezing of water Pieces of graft on and cut them up, especially since the circumferential beater with the interact with baffles fixed on the circumference. Larger chunks remain longer in the processing area until they can pass, so that the material flow to the Disperger becomes very even. It is then in the radially inner area of the Disperger sets further crushed and swirled, whereby very fine fiber crumbs arise.
- steam is fed into a downstream one following heating zone of the clothing to bring the fabric to the necessary temperature heat. As a result of the previous shredding, a relatively short one is sufficient Heating time off.
- the actual dispersion i.e. Change in the properties of the fabric takes place in the dispersion zone of the sets, which follows downstream.
- Fig. 1 shows sections of a system that is used to carry out the invention The method is particularly well suited. You can see that in the upper part of the picture Screw press 8, in which a large part of the water-containing paper pulp S1 of the water W is squeezed out. This makes a compact, highly consistent Fibrous material S2 is produced, which breaks off in large pieces at the end of the press section and through a short chute 10 into the distribution device 9 below falls.
- the flail roller 1 works on the Periphery, that is fixed to the housing of the distributor 9 Baffle pieces 3 together, so that the effect already described can occur.
- Such impact pieces can, as drawn here, rod-shaped with radial alignment be or e.g.
- the funnel passes through a drop funnel 11 thus treated highly consistent fibrous material S3 in a screw conveyor 7, which immediately before Disperger 4 is installed.
- This screw conveyor 7 drives the fibrous material S3 into the central area of the Disperger 4, so that it is between the Dispergergamituren 5 and 6 arrives and is dispersed.
- the gamituren have concentric axial interlocking rows of teeth that move past each other at a short distance become. The rotor and stator are therefore not pressed against each other.
- Such Disperger sets are particularly effective, but require uniformity Dispersion as even a material flow as possible.
- the substance is brought to a higher temperature for dispersion, for which purpose a steam feed 12 is present.
- this steam feed 12 becomes hot water vapor D in the space between the two disperser sets fed.
- This is expediently carried out in an annular heating zone 13, which is is located radially within the actual dispersion area 14 of the sets.
- the interlocking rows of teeth act in such a way that in the the highly consistent paper pulp is known to be dispersed. After that the dispersed paper pulp S4 emerges from the disperser through a bottom opening out.
- Fig. 2 illustrates the arrangement of the to carry out the method used devices in a different view, with a view of the Disperger 4.
- Distribution device 9 is not only an optimal distribution of the at Screw press 8 obtained material, but also the advantage of a space-saving arrangement achieved. If the process is carried out on an industrial scale namely, because of the relatively large quantities, a screw press 8 with a relatively large one Shaft diameters can be selected. The one at the end of the worm shaft Fibrous is not flowable and should therefore be essentially vertical can fall down.
- the location of the distribution device 9 in the manner shown enables the accumulation over the entire diameter of the screw press 8 Detect fiber and after appropriate treatment in the underlying Derive chute 10. It is therefore favorable to use the flail roller 1 at a right angle to the main conveying direction of the screw press 8. That unity Worm shaft and distribution device 9 can then relative to the Disperger 4 depending Space should be arranged appropriately.
- the basic structure of the distribution device 9 with the flail roller 1 is shown in FIG Fig. 3.
- the flail roller 1 with length L contains a number of flails 2, the circumscribe the outer ends on a circle with a diameter D. You work with them baffle pieces 3 fastened together on the housing 15 of this device. This will achieved that the incoming coarse paper pulp initially shredded becomes. The shredding takes place with relatively little force, which is what is to be attributed to the fact that the paper pulp obtained here is only compressed and that the only thing that matters is to dissolve this network. This is not comparable e.g. with the waste paper present in moist webs, e.g. in a fabric dissolver is processed.
- the distances a are expediently between axially adjacent fixed impact pieces 3 selected so that the highly consistent Fibrous material S2 is calibrated in between, so that too little is passed broken pieces of cloth is prevented.
- the particles passed through then have in a direction of extension a defined maximum dimension of e.g. 30 mm. Possibly must the distance a can be determined by a simple experiment. It could also be from Be advantageous to make it changeable so that the machine can work on different Requirements can be matched.
- the axial distance b between them encountering flails 2 and impact pieces 3 has a strong influence on the Shredding effect of this device. It is advantageously between 5 and 20 mm.
- the shape of the flail 2 or baffle 3 is appropriate to choose.
