Abstract
The invention discloses a manufacture process of all waste paper dried noodle cardboard paper, comprising the following steps: A: conveying the waste paper to a pulper through a scraper chain conveyor, and crushing the waste paper into paper pulp; B: conveying the paper pulp to a high concentration desander, and further removing the heavy impurities; C: screening out the pulp dregs and the impurities containing the heavy impurities from the paper pulp in a rough pulp tower by utilizing a three-section rough screen system; D: carrying out slag removal on the long fiber pulp by utilizing a long fiber three-section low concentration desander system, then feeding the fine pulp after the long fiber three-section low concentration desander into a three-section fine screen system to screen finely, and finally performing the paper making by utilizing a long fiber grinding back pool, a bottom machine chest and a paper remover; and E: carrying out slag removal on the short fiber pulp by utilizing a short fiber three-section low concentration desander system, and finally performing the paper making by utilizing a core machine chest and a paper remover. By utilizing the process provided by the invention, the product having the quality same as that of the dried noodle cardboard paper which is manufactured by the raw material of wood pulp can be produced, thereby greatly reducing the cost and ensuring the effective use of renewable resources.
Description
Technical field
The present invention relates to pulp technology for making paper, particularly relate to the preparation technology of full waste paper vermicelli boxboard.
Background technology
General primary wood pulp and the two kinds of raw materials of waste paper wood pulp of adopting of the preparation raw material of boxboard, primary wood pulp has better bursting strength and performance, but cost is higher, and waste paper wood pulp cost is lower but pretreatment process that needs are more, and intensity is relatively poor.Say that from the angle of environmental protection the trend in the industry is to reduce the use of primary wood pulp as far as possible, practicing thrift has the production-goods source, recycles renewable resource as much as possible.Do not have as yet at present and adopt the preparation technology of secondary stock fully as the raw material of vermicelli boxboard.
Summary of the invention
The preparation technology who the objective of the invention is to avoid weak point of the prior art and a kind of full waste paper vermicelli boxboard is provided.
The object of the invention is realized through following technical measures.
The preparation technology of full waste paper vermicelli boxboard, step comprises:
A: waste paper is delivered to the pulper size degradation through chain scraper conveyor become paper pulp, discharge simultaneously by the rubbish rope and pull out rubbish, and pull away said rubbish and the slag slurry that contains heavy seeds with car; The slag slurry that contains heavy seeds is discharged heavy seeds and mud through catch-basin, waterpower scarfing cinder machine, drum sieve and extruder;
B: said paper pulp is delivered to high concentration desanding device further remove heavy seeds, adopt intermittently deslagging mode, deslagging is drained through the sediment outflow machine, then said paper pulp is delivered to thick slurry tower;
C: the paper pulp in the said thick slurry tower is discharged slag slurry and the impurity that contains heavy seeds through three sections scalping screening systems; The slag slurry gets into catch-basin; Impurity is seen off with car after separator and extruder processing; Paper pulp behind discharge slag slurry and the impurity is divided into tail slurry and good slurry; Said tail slurry gets into pulper and reclaims; Good slurry through in dense desander get into fractionating screen after removing heavy seeds once more, be split up into long stuff and short stock;
D: said long stuff is after the slagging-off of long fine three sections low dense scummer systems; Three sections fine screens of good slurry entering through long fine one section low dense scummer select system to carry out the fine screen choosing; Mud row trench; Good slurry through one section fine screen gets into two sections lightweights except that slag system, light impurity row trench, and the good slurry entering polydisc thickener that removes slag system through one section lightweight concentrates; Then through the concentration of screw extrusion to 30%, helical feed is carried out heat to heat dispersion machine and is disperseed to remove sicker in the slurry, printing ink, resin, sticky matter such as cured; Said good slurry is delivered to the preceding stock tank of length fibre mill, is pumped into jordan then and carries out defibrination, after long fibre grinds after-bay, the bottom machine chest goes the paper machine to carry out papermaking;
E: said short stock is after the slagging-off of the low dense scummer of three sections of short fibers system; Good slurry entering polydisc thickener through one section low dense scummer of short fiber concentrates; Concentration through about screw extrusion to 30% then; Helical feed is carried out heat to heat dispersion machine and is disperseed with after removing sicker in the slurry, printing ink, resin, sticky matter such as cured, through short fiber reserve pit, short fiber blending chest, after the sandwich layer machine chest goes the paper machine to carry out papermaking.
Said waste paper comprises American waste paper, European waste paper and Japanese waste paper.
The part by weight of said American waste paper, European waste paper and Japanese waste paper is 60%:30%:10%.
The preparation technology of full waste paper vermicelli boxboard of the present invention is to the high request of the low operating rate of the outward appearance cleanliness factor of vermicelli boxboard and waste paper fibre; Produce and adopt wood pulp as the vermicelli boxboard of raw material product identical in quality; Cost significantly reduces, and has guaranteed effective utilization of regenerated resources.
The specific embodiment
In conjunction with following examples the present invention is described further.
The preparation technology of full waste paper vermicelli boxboard, step comprises:
A: waste paper is delivered to the pulper size degradation through chain scraper conveyor become paper pulp, discharge simultaneously by the rubbish rope and pull out rubbish, and pull away said rubbish and the slag slurry that contains heavy seeds with car; The slag slurry that contains heavy seeds is discharged heavy seeds and mud through catch-basin, waterpower scarfing cinder machine, drum sieve and extruder;
B: said paper pulp is delivered to high concentration desanding device further remove heavy seeds, adopt intermittently deslagging mode, deslagging is drained through the sediment outflow machine, then said paper pulp is delivered to thick slurry tower;
C: the paper pulp in the said thick slurry tower is discharged slag slurry and the impurity that contains heavy seeds through three sections scalping screening systems; The slag slurry gets into catch-basin; Impurity is seen off with car after separator and extruder processing; Paper pulp behind discharge slag slurry and the impurity is divided into tail slurry and good slurry; Said tail slurry gets into pulper and reclaims; Good slurry through in dense desander get into fractionating screen after removing heavy seeds once more, be split up into long stuff and short stock;
