Definitions

  • the invention relates to a pressure sorter according to the preamble of claim 1.
  • Pressure sorters are used in the processing of paper fiber suspensions, namely to process the fiber suspension in a wet sieving. To do this contains Such a pressure sorter has at least one sieve with a large number of openings is provided. The fibers contained in the suspension should pass through the openings step through it while rejecting the unwanted solid components on it and be routed out of the sorter. Pressure sorters can also be used Fiber fractionation are used in which the long fibers in the overflow and Pass the short fibers are enriched. As sorting openings are in the Usually round holes are used or slots. In most cases they are pressure sorters of the type considered here equipped with screen clearers that are close to the screen be moved past. As a result, the clogging of the Screen openings prevented.
  • the pressure sorters are basically both for the sorting of relatively coarse, as well as very fine contaminants.
  • Such sorters are not only used for the respective purpose by choosing the sieves themselves, especially their sorting openings also by constructive design of the machine and choice of operating parameters. It has meanwhile been able to produce sieves with reasonable effort, the very fine ones Openings, e.g. Have slots in the range of tenths of a millimeter. This succeeds separating even very small impurities from the fibers. This positive in itself However, development has led to the sieves and thus also the Sorting machines were getting bigger. The number of stages, i.e. the number of pressure sorter to be passed from the paper fiber suspension in succession greater.
  • WO 00/58549 A1 shows a sorter with a vertical housing, in which there are two screen elements flowed through successively by the paper fiber suspension to be cleaned are located.
  • the two screen elements are at least partially axially one inside the other pushed, which enables a compact design.
  • This sorter is also for the Rough sorting thought. With a rotatably driven screen basket, therefore Wear can be reduced, but this makes the machine complicated and expensive.
  • the invention has for its object to build a pressure sorter so that it is compact and has a good separating effect even with fine interfering substances and thereby one relatively high throughput allowed.
  • a pressure sorter designed in this way has the advantage that in one and the same Housing several, but at least two sorting operations carried out in succession can be. Optimal sorting quality is achieved with high throughput, because the flow control in the sorter was chosen so that the sieve baskets were centrifugal, that is, radially from the inside to the outside. A series connection of Highly effective sorters are otherwise only with considerable mechanical and technical control effort possible. With the invention, however, the number of Decrease pressure sorters significantly, even with high quality requirements.
  • a pressure sorter according to the invention offers particular advantages in fine sorting. Especially in the areas of fiber processing where it is a matter of removing particularly fine impurities (usually slot sorting is there the pressure sorters used for this must be relatively large. Only like that can ensure sufficient throughputs with the fineness of the sorting openings be promoted.
  • the invention unfolds its advantages particularly where the series connected Sieves are fine sieves and have approximately the same sieve characteristics, i.e. in the same Sort size range. This is especially the case when the sieves with similar or the same slots are provided, with a slot width of at most 0.8 mm, preferably less than 0.3 mm. It has been shown that in technical Applications often fail to sort a single level for the required quality is sufficient, especially if the contaminants are of the same order of magnitude how the fibers are, and therefore the sieve with a certain probability can happen. This also applies to the highly effective pressure sorters Schlitzsiebkörben. Critical contaminants are primarily adhesive particles (stickies). With This problem cannot be solved by narrower sorting openings. Therefore one must Another sorting step with the same effect with the already cleaned fabric be made to reduce the likelihood of elimination from severe to increase sortable substances.
  • the reject rate on the upstream sieve is significantly higher is set as the downstream.
  • the reject rate is the volumetric Quantity ratio of the overflow, based on the feed to the corresponding sieve. Because of the higher content of impurities in the feed to the upstream sieve, there can be a reject rate that is approximately twice as high as that of the downstream sieve can be set.
  • the pressure sorter according to the invention shown schematically in FIG. 1 has Housing 6 in which there are two sieves, namely the first - upstream - sieve 1 and the second - downstream - sieve 2.
  • the pressure sorter is like that built up that the inflowing through the overhead inlet 3
  • Paper fiber suspension S is first led to the feed side of the first screen 1.
  • On this inlet side there are clearing elements 7 and 8, which belong to the screen clearer 5.
  • the sieve is moved by the movement of the clearing elements 7 and 8 1 kept clear of constipation.
  • accept substance A1 After the paper fiber suspension S has the first sieve 1 has passed (accept substance A1), it first arrives in the first accept substance space 13 and then into the inlet area of the second sieve 2.
  • This sieve is used for sorting again carried out so that the part of the paper fiber suspension that also contains the second sieve 2 has passed through the accept material outlet connection 4 from the housing 6 as accept material A2 is brought out again. Both screens are radial from the inside out flows through.
  • the rejected forms a residue on the first sieve 1, which is caused by the first reject outlet 9 is discharged as the first reject R1.
  • Something similar happens on the second sieve 2 the residue of which is the second reject R2 through the reject outlet 10 leaves the housing 6.
  • a central light material connection 19 can be provided his.
  • Such a pressure sorter is usually constructed and assigned as a vertical sorter an underlying drive for the rotor 5, which serves to clear the screen. there allows the housing division 20 to remove the upper part of the pressure sorter. This is occasionally required to do maintenance work inside can. It is important that the rotor 5 and the sieves 1 and 2 are axial Do not hinder pulling apart. For this reason, it can be advantageous To make the inside diameter of the sieve 1 above smaller than that of the one below lying sieve 2. Another advantage of the arrangement shown here is in this, that the clearing elements 7 and 8 belong to the same rotor 5 for both screens 1 and 2 can.
  • the inlet spaces of the two screens are separated from one another by a plate 18 which is sealed in a contact-free manner against the rotor 5 by means of an annular gap 29.
  • a plate 18 which is sealed in a contact-free manner against the rotor 5 by means of an annular gap 29.
  • the plate 18 can be easily removed be divided so that the rotor can stop when the lower sieve is removed shall be.
  • the pressure sorter shown in FIG. 2 also has two screens 1 and 2, which are axial are so far apart that they are in different rooms. Unlike the sorter shown in FIG. 1, the fiber suspension S introduced into the housing 6 'via an inlet connection 3 located below. So that's why first flow through sieve 1 at the bottom and the second sieve 2 at the top. Acceptable substance A1, i.e. Passing through the first screen 1, the first accepting material space 13 becomes an external one - Here pump-free - pipeline 17 returned to the pressure sorter by enters an intermediate inlet 16, which is located on the upper part of the housing 6 '. The suction effect at the centrally located intermediate inlet 16 can transport the Support suspension.
  • the accept A1 passes from the intermediate inlet 16 into the inlet area of the second screen 2. If he has passed this and has entered the second accepting material space 14, he can led out of the housing as accept material A2 through the accept material outlet connection 4 become.
  • the accept outlet spout 4 is in the upper Part of the housing 6 ', that is shown above the housing division 20. With advantage (easy opening of the case) it lies in the lower part. Then there is one Appropriate material collection chamber 28 to be provided, as shown in Fig. 3.
  • the special one The construction of this pressure sorter allows - if desired - the two rejects R1 and to lead R2 out of the housing into a common reject outlet 11.
  • An aperture is used to control the reject flows provided, e.g. as part of the screen clearer 5, i.e. also rotating. It can be advantageous Aperture 12 to be adjustable.
  • the screen clearer 5 is drum-shaped here attached clearing elements, which can be similar to the case shown in Fig. 1. Variations of different clearing elements are possible at any time and adjust according to the existing conditions and requirements.
  • the housing fixed cutting disc 26 In cases in which the rejects are to be discharged separately, there is one in the housing fixed cutting disc 26 useful, as indicated in Fig. 3. It forms with a ring 12 'running around the rotor (not shown here in section) a sealing gap 27 which e.g. is about 1 to 3 mm wide.
  • the resulting very slight mixing of the two rejects R1 and R2 can be accepted.
  • 3 also shows the variant already mentioned: the accept outlet spout 4 is located below the housing division 20, which facilitates its opening.
  • the second accepted substance A2 For this purpose, the second accepting material space 14 becomes an accepting material collecting chamber 28 derived, which extends only over a small part of the housing circumference. To this is then the Gutstoffauslaufstutzen 4 connected.
  • a particularly compact and space-saving embodiment of the invention Pressure sorter results when the two sieves are pushed axially one inside the other are, i.e. are not in separate rooms. That leads to a low one Housing 6 ".
  • FIG. 4 Such an embodiment is shown in FIG. 4.
  • the introduced fiber suspension S introduced from above and radially from the inside out passed successively through the two screens 1 and 2.
  • the embodiment shown here has a special feature a rotatable inner strainer basket, which serves as the first strainer 1. In that the too this rotating sieve basket belonging to clearing elements 7 are fixed, the sieve is free held.
  • the first sieve 1 and the broaching elements 8 belonging to the second sieve 2 are disc-shaped Plate 24 attached. This forms the upper part of the screen clearer 5, from which it follows opening 6 "can be removed upwards.
  • the plate 24 contains Openings 25 for the incoming paper fiber suspension S.
  • the second screen 2 is in the Housing fixed.
  • Throttle ring 21 is present, which is shown only with regard to its function.
  • FIG. 5 Similar to the embodiment shown in FIG. 4, that of FIG. 5 has two axially sieves 1 and 2 pushed into each other, which are flowed through from the inside to the outside. However, both screens are fixed, while the clearing elements 7 and 8 on one common rotatable screen clearer 5 are attached. Again, the both rejects R1 and R2 are discharged separately, which has the advantage that differently designed chokes the reject currents can be easily controlled. Where that is not necessary, the two reject flows could also be through a common one Reject nozzles are derived.
  • the pressure sorter according to FIG. 6 is particularly favorable the center line 30 of the housing 6 ′′ ′′ does not coincide with the center line 31 of the rotor 5 together, this offset being the distance of the rotor from the two Acceptance connection piece 4 or 15 enlarged. That leads to simple means larger flow cross sections in the areas of larger accept material volume flows.
  • This eccentricity 32 can be approximately between 40 and 200 mm, depending on Housing size and is advantageously determined so that the flow rate of the Acceptable material flows cannot assume unfavorable values anywhere.
