Abstract
The present invention relates to a pulping process by using straws as raw material and its special equipment. Its technological process includes the followsing steps: cutting, removing dust, crushing, steam cracking, secondary crushing, glycolysis, separation, ball mill pulverizing and pulp-washing so as to can directly make primary corrugated paper and boxboard paper. In the course of pulping it doesnot use chemicals, does not produce black liquor, and has no pollution, and its crushing machine is simple in structure, its energy consumption is low and working efficiency is high.
Description
The invention belongs to the paper-making pulping process technical field, relate to a kind of technology and special equipment specifically with grass as raw material slurrying.
Straw pulp produces in the existing paper-making industry, mainly contain soda pulping process and sulfite pulping, these two kinds of method slurrying, all consume a large amount of chemicalss, the a large amount of black liquor that produce are the primary pollution source of present paper-making industry, mechanical feedback is mainly used in produces this slurry, utilize mechanical legal system straw pulp, still be in conceptual phase, be not applied to produce (" papermaking and equipment " chapter 1 the 7th joint China Light Industry Press in August, 93 version), chemical-mechanical pulping is after with cold alkali or sodium sulfite solution fibrous raw material being flooded, to carry out machinery again and grind and pulping, and this pulp-making method also produces a large amount of black liquor, for eliminating the pollution of black liquor to environment, need to drop into lot of manpower and material resources, therefore utilize not only production cost height of existing pulping process system straw pulp, and cause environmental pollution easily.
The purpose of this invention is to provide a kind of pollution-free system straw pulp technology and the special-purpose silk device that grinds.
This pulping process comprises the segment dedusting, steams to separate, push and separate and pulp washing, raw material after segment, the dedusting grinds the silk processing and steaming is separated, raw material after steaming is separated is again after secondary grinds silk, in fermentation tank, carry out glycolysis, the fermented feed liquid extruding separates, in the broken machine of ball, fiber is carried out the broken making beating of ball, make good slurry behind the pulp washing.
The stone roller silk device that is used for above-mentioned technology, it comprises frame, charging aperture, discharging opening, milling device and transmission device, milling device is provided with directly tangent and the grinding roller of reverse rotation each other, the power wheel interlock that two tangent grinding rollers are different with rotating speed respectively, and the grinding roller two ends are equipped with pressue device.
The present invention adopts the differential filament grinding machine that raw material is carried out twice stone roller silk and handles, fibre diameter after milling can reach below the 0.05mm, it is softening that fine fibre more becomes after glycolysis, slurry can manufacture paper with pulp behind the broken making beating of ball, pulp washing primary colors corrugated paper, wrapping paper, boxboard etc. do not use chemicalss such as alkali, sulphite again in this slurrying, do not produce black liquor, eliminated the environomental pollution source of paper-making pulping industry, grind the grinding roller differential running of silk device, high efficiency, energy consumption is low.
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 is a process chart of the present invention;
Fig. 2 is that the present invention grinds silk device side diagrammatic sketch;
Fig. 3 is filament grinding machine transmission principle figure.
With the wheat straw raw material is example, raw material is cut into 2 to 4 centimetres grass section, and behind dust removal of pneumatic separation, once grinding silk handles, the diameter that grinds silk back wheat straw fiber is sent wheat straw fiber into steaming and is separated in the jar below 0.15mm, feeds steam, 90-95 ℃ of control water temperature, after normal pressure steams and to separate 12 hours, will slightly starch to send into and carry out secondary in the filament grinding machine and grind silk and handle, obtain the slurry of fibre diameter below 0.05mm by carrying stock pump, slurry is sent in fermentation tank, inoculation yeast bacterial classification and cellulase preparation, control temperature 36-38 degree, feed liquid PH4 to 5, fermentation concentration 15%-20%, ventilation stirring 8 is the back blowing after a little while, and zymotic fluid carries out the broken making beating of ball to fiber in the broken machine of ball after extruding separates, the screened stock that makes is through pulp washing with after concentrating, the primary colors corrugated paper of can directly manufacturing paper with pulp, wrapping paper etc.
The stone roller silk device that is used for above-mentioned technology, it comprises frame (1), charging aperture (2), discharging opening (3), milling device (4) and transmission device (5), milling device (4) is provided with directly tangent and grinding roller reverse rotation each other (6a, 6b), milling device in the present embodiment (4) is made up of 2 groups of grinding rollers, grinding roller (6a, 6b) is made up of disk sand sheet (11) or Ceramic mill disc, power wheel (7a, the 7b) interlock that two tangent grinding rollers (6a, 6b) are different with rotating speed respectively, make the running of two grinding roller differentials, grinding roller (6a, 6b) two ends are provided with pressue device (10).
