Description
Technical field
The invention belongs to chemical fibre manufacturing technology field, relate to a kind of continuous material mixing, pulping, temperature adjusting integrated apparatus, relate in particular to and be applied in the solwution method spinning solution preparation process by before the continuous film evaporization process dissolving formation Polymer Solution, for obtaining having the abundant swellbility of homogeneous, have the pre-solution of the macromolecule a kind of continuous mixing, pulping, the temperature adjusting integrated apparatus that are adopted of good viscous state and shop film properties simultaneously.
Background technology
In the chemical fibre manufacturing technique, two kinds of main spinning modes of melt spinning and solvent spinning are arranged.As terylene, nylon fiber is to adopt the melt spinning mode to produce, this mode is to make it fusion to become mobile melt under the preference temperature that is higher than the macromolecule fusing point, form the melt thread through being pressed through spinneret orifice, obtain fiber through cooling curing and stretch orientation again.For the macromolecule that is difficult to fusion, as acrylic fibers, viscose then is to adopt solvent spinning production, it is macromolecule to be dissolved in according to certain solid content form solution in the solvent, forms the solution thread through being pressed through spinneret orifice, solidifies with stretch orientation and obtains fiber through deviating from solvent again.
The cellulose fiber by solvent method manufacturing technology becomes domestic and international hot of research and development in recent years.It is raw material that it and viscose adopt cellulose resource equally, but different is directly with solvent with cellulose dissolution, thereby more environmental protection of production process, the gained fiber integrates the advantages such as high mechanical properties of high molecular moisture absorption of native cellulose and synthetic fiber, has vast potential for future development.
In cellulose made by soloent process spinning solution preparation process, because the cellulosic material pulp is strong and volume is bulk to the absorbability of solvent, lyosoption heterogeneity when causing swelling easily causes the part pulp bad because of failing to absorb enough solvent swellings.On the other hand, solvent easily makes the surfaces of tacky of raw material pulp and influences the infiltration of solvent to core under higher concentration and temperature conditions, cause pulp core swelling bad.For avoiding the problems referred to above to take place, confirm by experiment, the ratio and the temperature of control solvent and non-solvent (as water) when feasible technological approaches is swelling, make solvent fully mix, permeate with pulp, make pulp obtain the homogeneous swelling, by improving pulping degree and temperature, obtain having the pre-solution of good viscous state and shop film properties subsequently.Pre-solution process thin film evaporation unit is sloughed the non-solvent (as water) of scheduled volume, removes bubble simultaneously, obtains homogeneous and dissolves bubble-free solution, obtains supplying the spinning solution of spinning through pre-filtering and static mixer mixing again.
About thin film evaporation unit, as far back as 1940, the Hans Mueller of Zurich, Switzerland has made first knifing thin film evaporator model machine, after this develop in Europe for continous mode knifing thin film evaporator, and in dry engineering and high molecular weight reactive engineering, begin to use extensive use aspect the evaporation in chemical industry, oil, dyestuff, food, medicine and wastewater treatment, fractionation, dehydration, deodorization, cooling, crystallization and the chemical reaction thereupon in nineteen sixty.(referring to patent ZL89106762.0) used in the beginning of the 1980's Mos in cellulose made by soloent process spinning solution preparation process, confirmed its industrialized feasibility subsequently, and the report (referring to patent CN96190636.7, CN96191361.4) of different structure and improved form has been arranged successively.
But, before forming solution, need prepare earlier and have the abundant swellbility of homogeneous by continuous film evaporization process dissolving, have the pre-solution of good viscous state and shop film properties simultaneously.Pre-solution has good viscous state and the shop film properties is very necessary, divide otherwise the solid, liquid two-phase that can occur solute and solvent in scraping membrane process separates and to take leave of wall and fall He Yanbi and flow down, be difficult to realize the thin film evaporation continuous-dissolution, this is confirmed from experiment.Therefore, realize that pre-solution viscous state shop film is one of key point of continuous stoste technology of preparing of thin film evaporation and device.As previously mentioned, desire to make the suspension of homogeneous, abundant swelling, need the ratio and the temperature of control solvent and non-solvent (as water),, easily cause the swelling heterogeneity, even form half-cooked white core if solvent strength or temperature are too high; Otherwise wish to get pre-solution, then wish solvent strength or temperature height with good viscous state and shop film properties.About how preparing the existing patent of the cellulose suspension with the abundant swellbility of homogeneous report, and clear and definite mentioning and concrete disclosure do not arranged as yet about the pre-solution problem that how to obtain having good viscous state and spreading film properties.
Report as ZL94190805.4, ZL94192189.1, ZL95193688.3, ZL97191328.5 etc. about the patent of cellulose suspension production method, wherein the suspension preparation among the ZL94190805.4 is divided mixing, two steps of pulping to carry out and is batch (-type); The mixing of suspension preparation, pulping carry out synchronously among ZL94192189.1 and the ZL97191328.5, are batch (-type); Suspension preparation is a continous mode among the ZL95193688.3, but the device that is adopted only plays immixture, must before mixing, the cellulosic material pulp be crushed to particle diameter≤4mm, and mentioned in the explanation before embodiment that the suspension that discharging opening is discharged carries out attrition process (pulping) subsequently again, but can not access pre-solution with good viscous state and shop film properties.
In view of this special proposition the present invention.
