Problems solved by technology

This, in turn, creates blockages on the refining surface, resulting in reduced refiner throughput and uneven quality of the refined material
This problem is particularly relevant to the refining surface of a refiner stator, since the stationary blade bars of the refining surface of a stationary refiner stator do not exert any particular force on the material to be refined, which would intensify The material to be refined passes through the blade grooves of the refining surface of the refiner stator

Embodiment Construction

[0028] figure 1 A side sectional view of a conventional disc refiner is schematically shown. figure 1 The disc refiner comprises two disc-shaped refining surfaces 1 and 2 arranged coaxially with each other. The first refining surface 1 is in the rotating refiner member 3, i.e. the refiner rotor 3, while the second refining surface 2 is in the stationary refiner member 4, i.e. the refiner stator 4 . The refining surfaces 1 and 2 of the refiner components 3 and 4 can be formed directly in these components or in a manner known per se from separate knife segments. The refiner rotor 3 is rotated in a manner known per se via a shaft 5 by means of a motor, not shown for clarity. There is also a special loading device 6 connected to the shaft 5. The loading device 6 is connected to the shaft 5 and acts in a manner that can push the rotor 3 to the stator 4 through the shaft 5 on the rotor 3 to adjust the relationship between the rotor 3 and the stator 4. The gap between, that is, t...

Abstract

A refining surface (2) of a refiner stator (4) for a refiner intended for defibrating lignocellulose-containing material. The refining surface (2) comprises a feed edge (17) oriented in the direction of the feed flow of the material to be refined, and a discharge edge (16) oriented in the direction of the discharge flow of the material refined. The refining surface (2) comprises blade bars (10) and blade grooves (11) therebetween, and at least one dam (12) arranged in at least one blade groove (11), the dam comprising at least one guiding surface (13), which rises upward from the direction of a bottom (15) of the blade groove (11), for guiding the material to be refined and the material already refined out of the blade groove. The upward direction of the guiding surface (13) of at least one dam (12) in the refining surface (2) is from the direction of the discharge edge (16) of the refining surface (2) in the direction of the feed edge (17) of the refining surface (2). In addition, a blade segment (18, 18', 18'', 19, 20) for a refining surface of a refiner stator and a refiner.

Description

Background technique [0001] The present invention relates to a refining surface of a refiner stator of a refiner for defibrating lignocellulose-containing material, the refining surface comprising a material to be refined along be refined) with a feed edge oriented in the feed flow direction and a discharge edge oriented in the discharge flow direction of the material refined, and the refining surface includes blade bars, blade grooves between the blade bars, and a blade groove disposed between at least one blade At least one dam in the chute comprising at least one guide surface rising upwards from the direction of the bottom of the blade chute for guiding material to be refined and material already refined to leave the blade chute. [0002] The invention also relates to a knife segment for the refining surface of a refiner stator of a refiner for defibrating lignocellulose-containing matter, which knife segment can be arranged to constitute the entire refining surface of the...
