Description
Technical field
The utility model relates to a kind of secondary stock fine-screening system.
Background technology
For paper grade pulp, by fiber raw material (normally timber), the paper pulp directly obtaining is referred to as protofibre or primary filament, and the paper pulp being made by waste paper is referred to as recycled fiber or secondary stock.
Fine screen is used in fiber recovery aspect and improves the quality of slurry conventionally, and its major function is to remove the impurity of slurry, as plastic sheet, and sicker and oarse-grained stain.Such sieve is arranged to several sections in use conventionally, and object is that fiber loss is dropped to is minimum.The slag slurry of final stage also comprises a certain amount of fibre bundle conventionally, and in order to reduce the fiber loss being brought by fibre bundle, defiberizing machine is used in before final stage fine screen sometimes, and this use has obtained certain success.
But use this class fluffer also to have a problem, conventionally the working clearance of fluffer be fixed and owing to discongesting the wearing and tearing of abrasive disc in process, discongest effect and progressively reduce, thereby cause fiber loss to increase.
And fibre bundle is not the unique factor that causes fiber loss, in whole screening system, the classification of each section is processed and has also been caused fiber loss.This means that in the slag slurry after each section of screening, long stapled content constantly increases, this has just caused the increase of follow-up workshop section fiber freeness.
High fiber freeness means that slurry can be easy to, dehydration fast, causes like this slurry in sieve, to be concentrated largely (concentration of slag slurry is compared to be increased in back segment step by step into the concentration of slurry).In order to ensure the runnability of sieve, thus the entering to starch concentration and must reduce step by step and just can avoid highly enriched and sieve seam to stop up of back segment.
Conventionally technical grade waste paper particularly, as waste and old corrugation boxboard (OCC), has higher concentrated trend, therefore must expand the width of follow-up workshop section sieve seam.The wide loss that certainly causes fiber of larger seam, also makes screening effeciency variation, means that like this quality of last pulping has also reduced.
Utility model content
Based on this, the utility model is to overcome the defect of prior art, and a kind of secondary stock fine-screening system is provided, and this secondary stock fine-screening system can reduce fiber loss, and can keep higher fiber quality.
