Definitions

  • the invention relates to a pressure sorter according to the preamble of claim 1.
  • Such pressure sorter is from the EP 0 487 224 A1 known.
  • Pressure sorters of this type are used in the treatment of paper fiber suspensions to process the pulp suspension in a wet sieving.
  • a pressure sorter contains at least one screen basket, which is provided with a plurality of openings.
  • the fibers contained in the suspension are to pass through the openings, while rejecting the unwanted solid constituents thereto and are led out of the sorter again.
  • a centrifugal procedure is used in which the suspension passes radially from the inside to the outside of the screen openings.
  • sorting holes are usually round holes or slots.
  • Pressure graders of the type considered here are equipped with sieve scrapers, which have close to the screen basket movable past clearing elements. As a result, clogging of the screen openings is prevented in a manner known per se.
  • the Siebshadowr is designed as a rotor, which is usually mounted concentrically to the screen basket.
  • the bearing housing of the sieve clearer must be sealed against the paper fiber suspension.
  • the sealing device required for this purpose is particularly stressed by the entrained in the paper fiber suspension impurities. In particular, heavy parts, such as pieces of wire, broken glass, sand and stones can penetrate to the seal and damage them. Even chains of staples and spun films or cords can cause problems in the seal.
  • the rotor is driven at Drucksortierern of the type considered here from the inlet side, so that the sealing device can come into contact only with the tapered suspension, which is not yet enriched as a result of the sorting process with impurities.
  • An example shows the US 6,679,384 B1 , It would be different with pressure sorters driven from the reject side, such as in accordance with the DE-A-199 11 884 ,
  • the release effect of a pressure sorter is therefore due to the fact that at least a part of the Contaminants contained in the paper pulp suspension supplied can not pass through the screen, so it is separated due to the size, shape or flexibility of the paper fibers.
  • pressure sorters in which an additional targeting on the density of the impurities separation is made by the different forces used in a centrifugal field of the impurities are used. Although a large part of the heavy parts would not pass through the screen openings usually used, so be rejected there, but there is a risk of damage or wear when they come into contact with the sieve.
  • the invention is based on the object of further improving the operational reliability and effect of the pressure sorters.
  • the feed space is arranged substantially annularly around the drive shaft of the sieve scraper and is replaced by a e.g. supplied tangentially scheduled feed with the pulp suspension to be sorted.
  • a rotational flow is formed in the inlet space.
  • the inventive design prevents the accumulation of air and / or light parts in the inlet space, since they can flow upwards along the projection because of their tendency to rise. Large heavy parts, such as Stones and wire pieces are thrown radially outwardly due to centrifugal forces and, in favorable embodiments, can be removed by a special heavy-part outlet so that they do not come into contact with the sieve.
  • FIG. 1 A typical embodiment of the pressure sorter according to the invention is shown in FIG. 1.
  • This contains in a housing 2 a cylindrical screen basket 1, whose center line is perpendicular in the position of use of the device.
  • the pulp suspension S to be screened is introduced into the housing 2 through an inlet 8. It first enters the inlet chamber 4, which extends substantially annularly around the drive shaft 16 of the sieve 7 and then into the overlying screen space 5.
  • the inlet 8 is here connected tangentially to the inlet space 4 , which increases the rotational flow during operation of the machine in the inlet space 4.
  • the accept which has come from the screen room 5 coming from the screen openings 19 of the screen basket 1, passes into the accepts space 3 and is discharged from this through the accepts outlet 9.
  • the accepts outlet 9 is arranged above the inlet 8, so that the main flow runs from bottom to top. Between accepts room 3 and inlet 4 there is a partition 20th
  • Sieve 5 In Sieve 5 is the Siebierr 7 with a rotor body 8, which is provided with a number of clearing elements 6. By relative movement to the surrounding liquid they produce pressure and suction surges, with which the screen openings are kept free.
  • the Sieblaker 7 is mounted in a flying manner in the lower part of the housing 2 (bearing unit 17) and is driven for rotation.
  • the larger heavy parts accumulate in the lower part of the inlet chamber 4 and are derived here via the Schwerteilauslass 13 in the heavy section lock 15.
  • the Schwerteilauslass is provided with an easily removable cover 21 or a cleaning flap to be able to clean if necessary. Because of the use of a Schwerteilschleuse 15 hardly arise fiber losses.
  • the largest part of the suspension rejected on the strainer basket 1, in particular the contaminants, are collected in the reject basket located above the strainer basket 1 and removed via the reject outlet as a reject R from the housing 2.
  • the reject R is usually sorted to avoid fiber losses.
  • the screening chamber 5 has at its uppermost part a vent opening 14, through the air and Light parts can be removed, which have flowed past the screen basket 1, without having passed the screen openings 19.
  • the features with which the pressure sorter is equipped according to the invention can be seen somewhat more accurately in FIG.
  • the rotor body 8 is shown only in its lower part, and it can be seen that the end face facing the drive (in this case the lower one) is provided with a frustoconical projection 11, which protrudes with its pointed end into the inlet space 4.
  • the projection 11 is dimensioned such that its smallest diameter D1 has approximately 30% of the value of the largest diameter D2. It is advantageous to keep the smallest diameter of the projection 11 small, so that the inclined surface extends as far as possible into the central region, which improves the elimination of light parts.
  • the resulting skew angle ⁇ is advantageously greater than 15 °.
  • the axial extent A1 of the projection 11 may amount to at least 20% of the axial extent B of the inlet space 4.
  • the screen chamber 5 opposite wall of the inlet chamber 4 is here provided with a projection 12 which extends into the inlet chamber 4 with a defined axial extent A2.
  • the interaction of these two projections 11 and 12 causes a central constriction of the flow cross-section in the inlet space 4, which leads to a significant improvement in the removal of lightweight materials and air and heavy parts.
  • This constriction continues in the example shown here to the sealing unit 18 with the smallest outer diameter D3.
  • the sealing unit 18 can be accommodated in the inlet space 4 because of their small footprint.
  • a tangential arrangement of the inlet 8 has the advantage that the pulse of the inlet flow is not directed to the sealing unit 18.
  • heavy parts e.g. Due to the centrifugal forces acting immediately in the inlet space 4, pieces of wire are prevented from reaching the central area in which the sealing unit 18 is located.
  • the storage unit 17, however, is located predominantly or as here completely outside the inlet space 4, which in particular has the advantage that the inlet space 4 can be aerodynamically optimized.
  • Fig. 3 is a plan view of the pressure sorter according to the invention is shown with a tangential inlet 8 and a radial Gutstoffauslass 9.
  • the partition wall 20 between Gutstoffraum 3 and Zulaufraum 4 is drawn through two broken lines.
  • a reject line 22 which is externally connected to the reject space 24, can open into the laterally attached heavy-part outlet 13.
  • the heavy-matter-enriched reject is discharged into the heavy-part outlet 13.
  • the pressure in the Rejektraum 24 can be increased by attached to the Sieb thriftr 7 blades 25.
  • the remaining part R 'of the reject can be removed by a side-mounted reject outlet 10 or via a reject outlet 10' (dashed line) leading upwards above the reject line 22.
  • the typical use case of this device is the pre- or coarse sorting of freshly dissolved pulp.
  • the screen openings 19 of the screen basket are then mostly round and have a diameter between one and three millimeters.
