FIELD OF THE INVENTION
The present disclosure relates to the field of refining equipment. More particularly, the present invention relates to paper pulp refining equipment.
BACKGROUND OF THE INVENTION
The conventional pulp refining method includes the refiner comprising a pair of refiner discs installed facing towards each other, wherein one of the refiner discs can be static and the other refiner disc can be rotating and said pulp refining takes place between the surface of said refiner disc by means of the plurality of ribs configured on the face comes in contact with the pulp. Further, said plurality of ribs configured on said refiner disc surface in a manner that the small races or gap between two ribs exist from an inlet end to an outlet end of said refiner disc, wherein the material feed to said refiner disc travels from said inlet end to said outlet end to perform the refining operation by means of said refiner disc. However, in the case of the full capacity operation with continuous operation at high speed contributes to the centrifugal force generation across the refining face of said refiner disc due to the high-speed rotation of said rotating disc. Said generation of centrifugal force across said refining face results in throwing away the material across said refiner disc leading to expelling the output with partial processing or non-processing to degrade the output quality for said refiner.
Further, said pair of refiner discs is intended to handle the plurality type of fiber which includes but not limited to short fiber, long fiber, or fiber from softwood or hardwood in accordance with the different application needs, processing type, and processing time. Wherein the adverse impact of said centrifugal force may impact the fiber treatment which requires long fiber retention time and processing time to process partially or non-processing to degrade the efficacy of said refining. Furthermore, the intensity of the material feed and stream escape depends on the gap between said rib, and refining capacity depends on the thickness of said rib which decreases due to the decrease in the specific edge length (SEL) and/or cutting-edge length (CEL) in case of thicker rib to reduce the refining surface for fiber treatment and refining time to deteriorate refining efficiency and efficacy. Therefore, it's intended that the refiner disc have a thinner rib with higher material retention time.
Furthermore, said thin ribs type of refiner disc are conventionally produced by means of the welded type of refiner disc comprises of a plurality of components which include but not limits to said rib configured with a tile, and the plurality of said tile configured with a common base plate in order to formulate said base plate. Whereas in said configuration of the rib with said tile and said tile with a base plate with thin ribs produces the weak juncture at the configuration of said rib and tile and said tile to base plate that leads to rib breakage and disc failure. Moreover, said problem of the rib breakage at the juncture is eliminated in the patent application no. 202321052743 published on 27th October 2023 that discloses the refiner plate configured with the dual configuration by means of vacuum brazing and positive interlocking method in order to enhance the durability and bonding of the refiner disc with the thinner bar up to 0.5mm in order to increase the number of a rib configured with a tile and base plate to increase the refining capacity and efficacy. Wherein said dual configuration of said vacuum brazing and said positive interlocking facilitates a robust juncture of said rib-to-tile configuration and said configuration of said rib-to-tile with said base plate in order to form a sector and configuration of said sector with the backup plate in order to formulate said complete refiner disc. At the same time, said thinner bar size with the rigid juncture configuration facilitates the higher quality of pulp refining quality with increased cutting edge length to enhance the material processing rate in order to boost the efficiency and efficacy of said refiner disc and said, refiner.
However, the addition of the flow restrictor within the pair of said ribs can enhance the versatility of said refiner disc by means of increasing in the material retention time to provide adequate time to process the fed material to said refiner disc to provide the capacity of handling plurality of refining material with mixed type of fiber length to reduce the refining cost and increase the operational range for said refiner disc in the pulp refining process.
Thus, the technological gap exists that is required to be alleviated by means of flow restrictor based formulation of said refiner disc by using said vacuum brazing and positive interlocking method.
SUMMARY OF THE INVENTION
The present invention envisages a variable rib refiner comprising a plurality of ribs configured with a tile and said tile configured with a base plate. Further, said plurality of rib configured with said tile and said tile configured with said base plate in a manner said ribs designed with the varied thickness or configured in zones with said varied thickness to articulate a varied valley in order to form a varied valley refiner disc. However, said configuration of said ribs and said tile, said tile and said base plate configured with said backup plate by means of vacuum brazing and positive locking means to articulate rigid and robust configuration of said refiner disc with fine and micro fine bar rib formulation to enhance CEL and SEL with higher life.
