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. needed to improve the quality of fiber, which was obtained from waste paper. It is known that pulp by Dispersing homogenized and can thus be significantly improved.
- a fiber is used that has a dry content between 15 and has 35% and has been brought to a temperature far above that Ambient temperature. It makes sense to heat up when the Fibrous material already has the consistency required for dispersion. With this Thickening process becomes a considerable part of what was previously in the pulp Water depressed, which firstly makes its viscosity essential when dispersing increases and secondly less water needs to be heated.
- the most important Thickening machines are screw presses and screen presses.
- the fibrous suspension is introduced and pressed between a screen and a roller or between two screens so that the water emerges. This creates a moist fibrous web.
- this membrane has a weight per unit area of between 500 and 2000 g / m 2 , although deviating values can also be useful.
- the wet web is removed from the area of the screen or screens and must then be torn into flat pieces. Although these can easily be brought to the desired temperature, a relatively long heating-up time is required. For example, warm-up times of several minutes must be accepted, especially if a temperature above 90 o C is desired.
- the hot crumb is then fed to the disperser. The whole requires a fairly complex system.
- the fiber suspension is between one Conveyor screw and a perforated jacket surrounding it, the Water leaks through the jacket.
- Shredding can e.g. in a shredder screw or a system with counter rotating Rotors are made, which is very expensive.
- the highly consistent paper pulp can either be used as a plug or in the form of a loose, only pre-shredded high consistency fabric directly into the clothing of one Dispergers can be entered.
- the fabric is then seen from the direction of flow the first crushing stage of the disperser is detected, crushed and swirled, whereby the fine fiber crumbs arise.
- the material is then cut to the necessary Temperature warmed up, due to the previous intensive crushing a relatively short heating-up time is sufficient.
- the actual dispersion i.e.
- the material properties change in the dispersion zone, which changes connects downstream.
- the version shown here is a disperger set with a radial flow of material, with a stator 2 and a rotor 4. In principle, could an axial disperger or kneader can also be used.
- the Disperger 3 shown here is loaded radially inside, for which a first in the center of the rotor 4 Comminution element 5 is attached, which e.g. wing-shaped or cross-shaped Crushing bars 6 can carry.
- the stopper 1 pressed here becomes peeled off or grated off and thereby broken up into fine crumbs, but here are not drawn.
- Primary stator teeth 7 slow down the fabric and lengthen it thereby its dwell time in the radially outer steam chamber 8 Impact of the fiber material thrown off by the comminution element 5 becomes this further divided. Crushing down to the size of the speck is an advantage Keep heating time low.
- the vapor space 8 is essentially ring-shaped and does not contain any of the mechanical ones Dispersion teeth.
- dispersion is brought about by the fact that Teeth are moved relatively close together at a relatively high speed and the fiber between them is subjected to strong shear forces. This function only has that which adjoins the steam chamber 8 radially further outside Dispersion zone 9. There are then high peripheral speeds of the dispersion teeth possible and advantageous, while the ones lying radially further inside Crushing bars 6 are slower and therefore the incoming stopper 1 shred gently. The substance is therefore not within the vapor space 8 mechanically dispersed. If necessary, however, internals 18 (FIG. 4) can be present that slow down the movement of the circulating fabric and loosen the fabric. The will be explained later.
- Heating steam ST is added via the steam pipes 11 brought into contact with the fiber. He is swirled in the steam room 8 or at least kept loosened so that it is well penetrated by the steam can.
- the heating is essentially achieved by condensation of the steam, i.e. Steam is constantly replenished.
- the make-up improves the swirl and the loosening of the fiber crumbs. After the dispersion, the dispersed falls Fibrous material S 'through outlet 13.
- the vapor space 8 is light due to the plug 1 and the substance in the dispersion zone 9 to seal against the outside world. It is also advantageous to terminate the dispersion zone 9 through a throttle ring 10 because this controls the degree of filling of the set leaves.
- a throttle ring 10 In connection with the invention is a high and uniform degree of filling particularly advantageous in the dispersion zone 9, because otherwise the outer diameter of the Disperger very large would have to be chosen to the desired specific To be able to transfer work to the pulp.
- a throttle ring is e.g. by DE 195 23 703 A1 is known.
- FIGS. 2a and 2b show a possible embodiment of the comminution element 5 in the Side view (2a) or top view (2b).
- the highly consistent paper pulp is not as compact Grafting, but pre-shredded into the more or less loose form Dispersing device is entered.
- a pre-shredded material falls e.g. when the thickening has been carried out on a screen press, from which the Thickened paper pulp runs out as a wet web.
- Crushing e.g. in a snail
- the fabric becomes so wide pre-crushed that it can be conveyed in screw systems.
- the pre-shredded material is then before entering the Disperger 3 '- as shown here in Fig. 2 - by a feed screw 16 detects and directly into the central inlet of the disperser 3 'performed.
- This feed screw 16 can have a stuffing effect, that is but not necessary to carry out the method according to the invention. Much more it can also be designed as a band screw, which is only on the outer diameter has a helical band 17 and comparatively promotes. With Advantage, the fabric in it can already be preheated, possibly for what existing steam lines 11 'serve. Then the crushing step gentler on fibers and later heating to dispersion temperature is faster. If the fabric is relatively loosely fed into the central inlet of the disperser, it does not offer the support of a solid plug, as shown in Fig. 1. The However, fine grinding is still possible because the material is less Radial speed than the shredding bars 6, which on the Crushing element 5 are attached. Often the primary stator teeth 7 in addition to their slowing effect, they promote comminution.
- the heating steam ST is added on radially outer edge of the steam chamber 8 and thus different than in Fig.1.
- This is supposed to Countercurrent heating can be achieved, which of course is a corresponding Centrifugal field in the steam room 8 provided.
- the steam swirls the crumb in the steam room additionally on. Similar considerations regarding the optimal dam addition locations are also in other configurations, e.g. to start according to FIG. 1.
- the inner row of the dispersing teeth 19 shown here belongs to the rotor.
- the fabric passes between these dispersing teeth and is pressed through the dispersing zone 9. In other cases, it can be advantageous to radially outer the vapor space through a To complete the row of teeth belonging to the stator.
