Abstract
The invention relates to a method used for preparing pulp by using tapioca root, which is characterized in that steps DS and FS are not used before the separation of short fibered pulp and long fibered pulp, and long fibered pulp goes through the step RF in advance, then goes through the steps which are the same as short fibered pulp. By adopting the tapioca root as raw material, the production cost is reduced, the tapioca root is found more easily, more materials can be selected during production, and higher-quality paper can be obtained because the leftover starch in tapioca root can tighten the fiber in the pulp and more completely fill the microcosmic gap.
Description
Technical field
The present invention relates to a kind of manufacture method of paper pulp, it is low to relate in particular to a kind of cost, and the measured manioc root material of pulpiness is made the manufacture method of paper pulp.
Background technology
Traditional employed raw material of paper pulp process industry are shredded papers, make according to following step:
1, HD (hydra pulper) step: mixing with water with raw material, is shredded paper at these raw material, and keeping its concentration proportion is about 4-10%, after enter next step;
2, DS (drum sorter) step: impurity is separated, separates the paper delivery slurry as plastics, rope, stone, iron etc., after enter next step;
3, HC (high consistency cleaner) separating step: proportion is separated greater than the impurity of paper pulp,, entered next step after with the knockout press of concentration 4-10% it being separated as husky, stone and other;
4, FS (fiber sorter) step: removing impurities such as plastics etc. separate from paper pulp and enter next step;
5, FF (fiber fretter) step: divide slurry, distinguish long fiber pulp and short fibered pulp, the long and short fiber slurry after will separating then enters next step separately;
Afterwards, the long and short fiber slurry will separate, and enter step separately:
6, LC (low consistency cleaner) step: separate the material of proportion with proportion less than the knockout press of the paper pulp of 1% concentration, and enter next step greater than paper pulp;
7, LLC (light weight low consistency cleaner) step: separate the material of proportion less than the knockout press of the paper pulp of 1% concentration less than paper pulp with proportion;
With the isolated short fibered pulp of LLC mode, enter the following step:
A, FC (fine screen) step: filter the material be mixed in the paper pulp, after enter next step;
B, DW (dewatering (thickener)) step: the moisture in the paper pulp is separated, makes it remain on concentration proportion about 30%, after enter next step;
C, RF (refine) step:, make it measure-alike or close with the careful roll extrusion of paper pulp.
With the isolated long fiber pulp of LLC mode, enter the following step in addition:
A, FS step: removing impurities such as plastics etc. separates from paper pulp, enters next step;
B, DW step are separated the moisture in the paper pulp, enter next step after making it remain on concentration proportion about 30%;
C, DISP (dispersion) step with the coarse roll extrusion of paper pulp, enters next step after making the subtitle substance that can't filter such as grease etc. be uniformly distributed in the paper pulp with the temperature of 70-95 degree Celsius;
D, RF (refine) step:, make it measure-alike or close with the careful roll extrusion of paper pulp.
Above-mentioned steps is to be raw material with the shredded paper, and price is more expensive, and collects more time-consumingly, is necessary to change into as much as possible raw material more cheap and that be easier to seek.
Summary of the invention
The object of the present invention is to provide a kind of cost low, the measured manioc root material of pulpiness is made the manufacture method of paper pulp.
For achieving the above object, the invention provides the manufacture method that a kind of manioc root material is made paper pulp, it comprises the following steps:

Step 1, HD step: mix with water with raw material, these raw material comprise manioc root, and keeping its concentration proportion is 4-1 about 0%, and above ratio is a weight ratio, after enter next step;
Step 2, HC separating step: proportion is separated greater than the impurity of paper pulp,, entered next step after with the knockout press of concentration 4-10% it being separated as husky, stone and other;
Step 3, FF step: divide slurry, distinguish long fiber pulp and short fibered pulp, the long and short fiber slurry after will separating then enters next step separately;
Afterwards, the long and short fiber slurry will separate, and enter step separately:
Wherein, handling the short fibered pulp following step has:
Step 4, LC step: separate the material of proportion with proportion less than the knockout press of the paper pulp of 1% concentration, and enter next step greater than paper pulp;
Step 5, LLC step: separate the material of proportion less than the knockout press of the paper pulp of 1% concentration less than paper pulp with proportion;
Step 6, FC step: filter the material be mixed in the paper pulp, after enter next step;
Step 7, DW step: the moisture in the paper pulp is separated, makes it remain on concentration proportion about 30%, after enter next step;
Step 8, RF step:, make it measure-alike or close with the careful roll extrusion of paper pulp;
Wherein, handling the long fiber pulp following step has:
Step 4, LC step: separate the material of proportion with proportion less than the knockout press of the paper pulp of 1% concentration, and enter next step greater than paper pulp;
Step 5, LLC step: separate the material of proportion less than the knockout press of the paper pulp of 1% concentration less than paper pulp with proportion;
Step 6, FC step: filter the material be mixed in the paper pulp, after enter next step;
Step 7, DW step: the moisture in the paper pulp is separated, makes it remain on concentration proportion about 30%, after enter next step;
Step 8, RF step:, make it measure-alike or close with the careful roll extrusion of paper pulp.
Also comprise a RF step before the step 4 of processing long fiber pulp: with the careful roll extrusion of paper pulp.
Raw material in this step 1 are manioc root.
Raw material in this step 1 are the mixture of manioc root and shredded paper.Manioc root proportion 5-50% wherein, shredded paper proportion is 95-50%, is weight ratio.
Raw material in this step 1 are the mixture that manioc root and shredded paper, wood fragments are considered to be worth doing.Wherein manioc root proportion is at 5-50%, and the proportion of shredded paper and wood fragments bits is 95-50%, and above ratio is a weight ratio.
Make paper with this paper pulp and comprise that a step is: when paper pulp being tiled on the superfine sieve of sieve aperture or on the calico, make the moisture natural evaporation, get final product whole paper.
Resulting fiber pulp is a dried fiber pulp that wet or spendable.
The present invention has following beneficial effect: among the present invention, use more cheap and the manioc root that is easier to seek or manioc root and shredded paper, sawdust mixture are produced paper as raw material, not only reduced cost, and since in the manioc root residual starch make in the paper pulp fiber more fastening, the better filling in microcosmic gap is satisfactory, the pulp quality that obtains is higher, and paper quality is better.
