Description
Technical field
The utility model belongs to papermaking slurry technology and equipment field, relates generally to a kind of low energy consumption, free of contamination paper-making pulping device.
Background technology
In traditional system pulping process, for fiber separation is come out, commonly used have soda pulping process and sulfite pulping two big classes, will use a large amount of chemical reagent in this process.On the industrial production chemical pulping comprise get the raw materials ready, boiling and three basic craft course of purification.Boiling vessel is the basic equipment of chemical pulping digestion process, and the main part of various boiling vessels is the bigger metal pressure vessel of volume, the equipment complexity, and investment is high, and the operational administrative level requires also high.Thick slurry through boiling is made just can become available paper pulp through suitable purification.The purification of paper pulp generally comprises processes such as washing, screening, bleaching.In the technical development of chemical pulping, existing method is exactly the waste material that gives off a---black liquor to the pollution of environment maximum.The black liquor silicon content is big, viscosity is high, drainability is poor.The waste water of paper industry is if handle and enter in the rivers through not imitating, the organic substance fermentation in the waste water, oxidation, decomposition, and the oxygen in the consume water causes death aquatile anoxics such as fish, shellfish; Some tiny fiber suspensions at water are, stop up the fish gill easily, also cause fish kills; Bark bits in the waste water, wood chip, grass bits, corruption grass, rotten slurry etc. sink under water, and silt the riverbed up, in slowly fermenting, constantly produce malicious foul smell; Also have some to be not easy the material that ferments, decomposes in the waste water, be suspended in the water, absorb light, reduce sunlight and penetrate river, hinder the photosynthesis of water plant; Have in addition that some are carcinogenic, teratogenesis, mutagenic poisonous and harmful substance.In a word, paper waste makes turbid black, the stench of river, and pasture and water do not give birth to, and fishes and shrimps destroy the evidence, and mosquitos and flies grows thickly, maggot everywhere, the littoral resident's of serious threat is healthy, causes diseases such as dysentery, enteritis, scabies in vogue, simultaneously, also is unfavorable for field irrigation and human livestock drinking water.In many water contamination accidents, the Huaihe River contamination accident is the typical case relatively.Because paper plant's blowdown along the river is serious, the Basin of Huaihe River water environment worsens day by day, and by 2004, overflowed in middle and lower reaches Heisui River, Huaihe River, the fishes and shrimps disappearance, and the routed of whole water system just avoided in government has had to rely on the administration means positive closing many little paper mills.
Summary of the invention
The purpose of this utility model provides a kind of method and device thereof of paper-making pulping, makes it finish frotation and fibrillating in pulping process, thereby realizes low energy consumption, pollution-free.
The purpose of this utility model can adopt following technical scheme to realize: it comprises main body, motor, main body is provided with charging aperture, charging aperture communicates with the cylindrical shell of setting in the main body, having in cylindrical shell has helical axis, one end of helical axis is connected with motor, the axostylus axostyle of helical axis is diameter cumulative pyramidal structure from the charging aperture to the discharging opening, has helicla flute on the inwall of cylindrical shell, and the spiral fluted degree of depth is successively decreased from the charging aperture to the discharging opening successively.
Described cylindrical shell is made of main cylinder and extruding cylindrical shell, the recipient body be positioned at main cylinder afterbody, the extruding cylindrical shell is that inwall is the cylinder of light face, the afterbody of helical axis extend in the extruding cylindrical shell, gap between the tail end of helical axis and the extruding inwall forms discharging opening, is provided with cooling body in the recipient external body.
Described extruding cylindrical shell afterbody is by the ring flange chucking that is connected on the main body, the front end sleeve of extruding cylindrical shell is on the step of main cylinder rear end, the extruding cylindrical shell is provided with the locating shaft that front end is taper, and locating shaft one end is positioned at the location taper hole on the helical axis afterbody.
Utilize method and apparatus described in the utility model, can finish frotation and fibrillating to raw material (as straw), make the fibrous raw material rotation at a high speed between helical axis and cylinder inboard wall that enters into inner barrel, successively decrease from the charging aperture to the discharging opening successively in the axostylus axostyle of helical axis and the gap of cylinder inboard wall, simultaneously successively decrease from the charging aperture to the discharging opening successively in helical tooth on the helical axis and the helicla flute gap on the cylinder inboard wall, can make raw material be rubbed repeatedly, push in cylindrical shell like this and produce high temperature (can reach 180 ℃～250 ℃), high pressure and (can reach 6MP～8MP).Paper pulp raw material is that discharging opening is extruded from the slit between helical axis afterbody and the main frame cover, when raw material under the situation of the unexpected release of pressure in discharging opening place, can make raw material puffed explosion finish frotation and fibrillating.Utilize device described in the utility model to make stalk make fibrous product as paper pulp, itself and later stage soaking technology can not pollute environment in conjunction with no waste gas, discharging of waste liquid.Raw material is carried out frotation to the utility model and fibrillating is handled, and can make straw not add chemical reagent in the system pulping process, thoroughly controls stench and sewage that alkaline hydrolysis discharges, is a kind of environment friendly and pollution-free technology.Device described in the utility model carries out after frotation and fibrillating handle raw material, and slurry yield improves, and has the performance of chemical pulp, is example with the straw, and slurry yield is more than 85%.
The utility model is handled raw material (straw) frotation and fibrillating, makes paper pulp again and can make whole pulping process small investment, and the popularization that this kind paper pulp is made for paper-making industry, has solved the shortage of resources problem.Every mu of ground of peasant is increased income about 200 yuan.Because pollution-free, actual present little paper mill need not to close, device resource will obtain preserving.Therefore, have important social benefit and economic benefit.
