Background technology:
Along with the application of economic development and new high-tech material, the strong high modulus fiber range of application of superelevation enlarges gradually, and the existing carbon fiber of existing market, aramid fibre etc. cost an arm and a leg because of it, use limited.In recent years, domestic utilization changes technology such as the regularity of PVA molecule and the degree of polymerization, develops super high strength high modulus PVA long filament, obtains certain progress, but still seldom arrives intensity greater than 17g/d, the modulus product greater than 400g/d.
Industrially generally produce vinal through wet spinning with the PVA aqueous solution, mechanical performance for fibres modified, as in spinning solution, adding boric acid or boratory method, through wet spinning with after being no less than 10 times extension, carrying out contraction heat in certain scope handles, though these fibers have been widely used in each industrial circle, its intensity and modulus are still low than aramid fibre.In order to improve intensity and modulus, spin solvent had been proposed already with organic solvent and without aqueous solvent, and employing dry-wet spinning technology, disclosed at present spinning extraction equipment mostly is the slot type structure, spinning solution sprays into from an end, tow is derived from the other end of groove, and then enters extraction tank and extract, and its shortcoming is as follows:
1, in the groove guide rod is set, draws silk inconvenience;
2, easily produce doubling, lousiness and curling round the roll, make to produce and be forced to interrupt, the spinning operation is unstable;
3, because extract mostly is lower boiling methyl alcohol or carbinol mixture, and its uncovered structure easily causes a large amount of volatilizations of extract, consume height, be unfavorable for safety in production and environmental protection;
4, equipment is long, and the people operates in the side, and floor space is big.
Summary of the invention:
Technical problem to be solved in the utility model is to avoid above-mentioned existing in prior technology weak point, provide a kind of stable, be beneficial to safety in production and environmental protection, and can obtain the dry-wet spinning extraction equipment of satisfied spinning effect of extracting.
The technical scheme that is adopted when the utility model addresses the above problem is:
Design feature of the present utility model is the top that spinning head is positioned at the spinning machine coagulating tank, air layer is arranged therebetween, in described coagulating tank, be positioned at spinning head below guide plate is arranged, the extraction equipment that setting is made of extraction hopper and extracting tube, wherein, the extraction hopper is positioned at a side of spinning machine, and there is guide roller its top; Extracting tube is connected the bottom of extraction hopper, and extract and tow go downstream therein.
Stoste sprays through spinning head, through behind the air layer of certain altitude, enter in the lower coagulating tank of temperature, move towards according to tow, behind guide plate, deflector roll, extraction hopper, extracting tube, draw after extracting the extraction silk, this silk obtains intensity and is not less than high strength, the modulus poly (vinyl alcohol) fibers that 17g/d, modulus are not less than 400g/d after super drawing.Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model coagulating tank inner structure is simple, does not need to be provided with guide rod; Do not add to appoint in its extracting tube and close member, do not have doubling, lousiness and collaring, it is convenient to draw silk.
2, the utility model comprises the coagulating tank and the extracting tube of spinning machine, and whole device is similar to enclosed construction, and volatilization is few, when reducing consumption, helps safety in production and environmental protection.
3, the utility model adopts vertical structure, and floor space is little, convenient operation and management.
4, the recyclable utilization of solidification liquid in the utility model and extract.
Fig. 1 the utility model structural representation.
Fig. 2 is that Figure 1A is to view.
Fig. 3 is that Figure 1B is to view.
The specific embodiment:
Referring to accompanying drawing 1, spinning head 8 is positioned at the top of spinning machine coagulating tank 11, and air layer 16 is arranged therebetween, and the height of air layer 16 is 2～200mm.
In coagulating tank 11, be positioned at spinning head 8 below guide plate 7 is arranged.
The extraction equipment that setting is made of extraction hopper 3 and extracting tube 2, wherein, extraction hopper 3 is positioned at a side of spinning machine 12, and there is the guide roller 5 that the tow in the coagulating tank 11 is drawn its top; Extracting tube 2 is connected the bottom of extraction hopper 3, and extract and tow 4 go downstream in extracting tube 2.
In the coagulating tank 11 of spinning machine, its solidification liquid inlet 13 is positioned at spinning head 8 places one side, be provided with in its porch make solidification liquid and spray silk and stream, and around the ring diversion plate of spray silk, this ring diversion plate constitutes (as shown in Figure 2) jointly by vertical distributing pore plate 9 and horizontal distributing pore plate 10.Small aperture on vertical distributing pore plate 9 and the horizontal distributing pore plate 10 is not less than 0.1mm, this ring diversion plate can effectively be controlled the solidification liquid flow direction, make solidification liquid enter behind the spinning machine coagulating tank can from around flow into the spinning zone, be evenly distributed in then every rhizoid around, follow the tow direction of motion and tow paired running, and turn to the spinning machine outlet at the guide plate place, finish physics and chemical process that gel spinning forms the nascent state fiber simultaneously, such structure is provided with to be beneficial to and simplifies the operation, steady production, and form good nascent state fiber.Solidification liquid overfall 14 is positioned at bottom, extraction hopper 3 places one side of spinning machine 12, and solidification liquid liquid level adjustable plate 6 is set, and can regulate the air layer height very easily by adjusting the liquid level of solidification liquid.
Extract inlet 15 is positioned at the bottom of spinning machine 12, the side of extraction hopper 3.Extract enters extraction hopper 3 from spinning machine bottom, the energy that the tow paired running that comes with spinning machine then, tow flow by extract together forward and finish the extraction process of continuous mass transfer.
Extracting tube 2 can be straight tube or bend pipe or helix tube, can be more crooked when extracting tube 2 is longer, and radius of curvature should be greater than 8mm, and any member is not established in the inside of extracting tube 2, and its total length is no less than 10 meters, and diameter is 2mm～100mm.In the exit of extracting tube 2 throttle orifice 1 is set, the throttle orifice diameter is at 2～50mm, and throttle orifice is in order to the flow velocity of extract and the size of flow in the adjusting extracting tube.During less than 50mm, also can not establish throttle orifice at the extracting tube internal diameter.
During concrete enforcement,, can be that single-stage also can be a plural serial stage by the extraction equipment that extraction hopper 3 and extracting tube 2 constitute.
Filter qualified stoste, after the voltage stabilizing metering, enter spinning head 8 and spray downwards, enter behind the air layer by certain altitude in the lower coagulating tank of temperature 11, form the as-spun fibre of even frozen glue form.It is big intermolecular because of Van der Waals force forms crosslinkedly for this fiber, belongs to the fiber of intermolecular cross-linking.Owing to contain a large amount of solvents in the nascent state fiber, so in pilot scale and trial production process, extraction process need be set, the nascent state fiber be extracted with the extract of certain composition, make the solvent in the nascent state fiber drop to standard level, the fiber after extraction can be delivered to drawing machine and carry out drawing-off.
