Definitions

  • the invention relates to a pressure sorter for cleaning a pulp suspension with a Siebense rotationally symmetrical trained sieve element, which divides the pressure sorter into a Zulaufraum and a Gutstoffraum, the Zulaufraum at one axial end with a suspension inlet and at the opposite axial end with a Rejektauslauf and Gutgutraum is associated with a Gutstoffablauf in connection and in the Zulaufraum a rotor with rotor blades, the axis of rotation of the Siebachse corresponds and rotates relative to the screen element, wherein the rotor blades are arranged distributed over a plurality of perpendicular to the rotation axis circumferential planes of the rotor.
  • Pressure screens are used in the processing of paper pulp suspensions, in order to process the pulp suspension in a wet sieving.
  • a pressure sorter includes a sieve element which is provided with a plurality of openings. The fibers contained in the suspension are to pass through the openings as accept, while the unwanted solid constituents are rejected thereon and discharged as a reject again from the sorter.
  • a Sieb thriftr which is provided with wing elements for the clearance of the screen
  • These wing elements have a hydrodynamic profile, which extends over the entire length of the screen element, a screen basket. Due to the relative movement to the surrounding suspension there the wing element at the front a pressure and behind a suction pulse on the screen to be cleared. Thereby, a part of the suspension, which was rejected on the screen or has already passed through the screen as accepts, sucked back, whereby the screen openings are kept free or cleared.
  • the rotor blades are formed for example in DE-OS 3701669 of surveys.
  • the object of the invention is therefore to reduce the energy intake and the risk of clogging with the simplest possible means.
  • this object is achieved in that the width of the annular gap between the rotor and the screen element decreases from the suspension inlet to the reject outlet.
  • the width of the annular gap decreases in steps or continuously. In view of ease of manufacture, the reduction in stages is preferable.
  • the rotor should have at least one recess in at least one circumferential plane between the rotor blades. Furthermore, it has proved to be optimal if the rotor has at least three circumferential planes with rotor blades and / or each circumferential plane has two rotor blades each and / or the rotor blades have the same shape.
  • the rotor blades adjacent circumferential planes should be arranged circumferentially offset from each other. This also counteracts clogging.
  • the axis of rotation In order to achieve a transverse flow in the axial direction across the sieve element, the axis of rotation should be inclined or perpendicular to the machine plane.
  • the rotor is located inside the sieve element, the sieve element is cylindrical and the rotor is designed as a cylindrical drum.
  • the suspension feed should be arranged below the reject outlet.
  • Figure 1 a schematic cross section through a pressure sorter parallel to the axis of rotation 10 and
  • Figure 2 a cross section through the rotor 8 perpendicular to the axis of rotation 10.
  • the pressure sorter has a screen element 2, here in the form of a cylindrical screen basket with vertical Siebachse 1, which the interior of the pressure sorter in an inlet space 3 and a Acceptance space 4 divides.
  • the pulp suspension is fed via a suspension feed 5 at the lower end of the screen basket.
  • the pulp suspension receives an angular momentum which causes it to move circumferentially.
  • a transport flow is generated as a result of the applied pressure gradient between the lower suspension inlet 5 and located at the upper end of the screen basket Rejektauslauf 6 of the inlet chamber 3.
  • the rejected from the screening element 2 part of the pulp suspension is conveyed as a reject over the Rejektauslauf 6 from the inlet space 3.
  • a known Sieblaker is used, which moves relative to the screen element 2.
  • this sieve clearer is formed by a rotor 8 rotating in the screen element 2 with rotor blades 9 fastened thereto.
  • the rotor 8 has the shape of a cylindrical drum, wherein the axis of rotation 10 coincides with the Siebachse 1.
  • All rotor blades 9 in this case have the same shape, which leads to a uniform effect on the pulp suspension and the screen element 2.
  • the rotor blades 9 are arranged distributed over several, here three perpendicular to the rotation axis 10 extending circumferential planes 1 1 of the rotor 8, wherein each circumferential plane 1 1 more, here two rotor blades 9 has. It is essential, however, that the width of the annular gap 12 between the rotor 8 and the screening element 2 decreases from the suspension inlet 5 to the reject outlet 6 in stages. Expediently, the stepped transitions are each between two adjacent circumferential planes 1 1. Since the screen element 2 has a cylindrical shape, this means that the diameter of the rotor 8 increases discontinuously from bottom to top.
  • the invention is also successful in other forms of rotor blades 9.
  • the production is particularly simple if the rotor blades 9 are formed by elevations on the rotor 8.
  • the radial extent of the rotor blades 9 decreases in stages, i. the height of the elevations on the rotor 8 decreases from the suspension inlet 5 to the reject outlet 6 in stages, whereby here too the steps between the circumferential planes 1 1 lie.
  • the running in the direction of rotation of the rotor 8 cross-sectional area of the rotor blade 9 is formed as a rectangle.
  • the blades 9 have not only the same shape but also the same dimensions, which reduces the cost.
  • the rotor blades cover 9 a circumferential plane 1 1 completely in the direction of rotation.
  • the rotor 8 has in each circumferential plane 1 1 between the rotor blades 9 at least one recess 13, which, however, extends only over part of the axial extent of the respective circumferential plane 11.
  • the rotor blades 9 adjacent circumferential planes 1 1 offset in the circumferential direction to each other.

Abstract

L'invention concerne un classeur sous pression, servant à purifier une suspension de matière fibreuse, qui comprend un élément de tamisage (2), ayant une configuration symétrique en rotation autour d'un axe de tamis (1), qui partage le classeur sous pression en un compartiment d'alimentation (3) et un compartiment de matériau fini (4). Le compartiment d'alimentation (3) communique à une extrémité axiale avec une arrivée de suspension (5) et à l'extrémité axiale opposée avec une évacuation de matériau rejeté (6). Le compartiment de matériau fini (4) communique avec une évacuation de matériau fini (7) et il contient un rotor (8) équipé de pales de rotor (9) dont l'axe de rotation (10) correspond à l'axe de tamis (1) et qui tourne par rapport à l'élément de tamisage (2), se trouve dans le compartiment d'alimentation (3). Les pales de rotor (9) sont réparties sur plusieurs plans circonférentiels (11) du rotor (8) qui s'étendent perpendiculairement à l'axe de rotation (10). Selon l'invention, la consommation d'énergie et le risque de colmatage sont réduits grâce au fait que la largeur de l'interstice annulaire (12) entre le rotor (8) et l'élément de tamisage (2) diminue depuis l'arrivée (5) de la suspension en direction de l'évacuation (6) du matériau rejeté.
