Detailed description of the invention

Fig. 1 is the schematic diagram of an example of continuous polymerization system 100.As shown in Figure 1, continuous polymerization system 100 comprises a series of parts, it is configured to polymerization and little by little produces more HMW (higher relative viscosity) polymer, such as polyamide, as repeated the aliphatic polyamide (such as, nylon) between amide units with at least 85% aliphatic key.Polyamide can be the polyamide of any appropriate, as nylon 6, nylon 7, nylon 11, nylon 12, nylon 6,6, nylon 6,9; Nylon 6,10, nylon 6,12, or their copolymer.

Continuous polymerization system 100 is configured to pass and makes the aqueous solution of diamines-dicarboxylate prepare polyamide at super-atmospheric pressure continually by continuous reaction zone.In acid amides formation temperature, from diamines-dicarboxylic acids salting liquid of providing of salt supply storage 102 by having at least one of the reaction zone 104 (such as, reactor, flash vessel, finisher etc.) of one or more parts.Salting liquid makes most salt be converted into polyamide by the speed that each parts are advanced.Polyamide reaction composition, when the pressure of the formation still in acid amides formation temperature and at permission steam, afterwards by least one other parts of reaction zone.In the compartment that this is other, water is little by little removed as steam from response composite.Finally, composition comprises molten polyamide, and pressure is atmospheric pressure substantially, and the logistics of continuous polymerization is simultaneously left from reaction zone.As shown in Figure 1, continuous polymerization logistics is delivered to one or more streamline end component, comprises, such as respectively by polymer spinning for fiber or be fiber spinning machine or the comminutor (being shown as parts 106) of pellet by forming polymer.

Referring again to Fig. 2, in an example, finisher assembly 200 comprises agitator 214.As shown, agitator 214 is connected with the screw rod 212 of screw pump 210.Therefore, the rotation of screw rod 212 is passed to agitator 214 to stir the polymer fluid 228 in (as described herein, mixing and wiping) melt pool 224.Polymer in melt pool 224 mixes by stirring consistently that provided by agitator 214, heat is distributed from heat exchanger jacket 227, and the generation of delayed gel in melt pool 224.As shown in this example, agitator 214 comprises near outlet opening 208 to the hurricane band 216 that the water front of melt pool 224 or upper surface extend.Hurricane band 216 comprises the periphery closely adjacent with inner reservoir wall 229 (such as, outward flange) (such as, within the about 1.3cm of wall, or within the about 0.6cm of wall, as at about 0.000 of wall, within 1cm to about 1.3cm or about 0.6cm, as left wall about 0.000,1cm or less, or leave wall about 0.000,5cm, 0.001,0.005,0.01,0.05,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1,1.1,1.2 or about 1.3cm or larger).Therefore polymer fluid is wiped along inner reservoir wall 229 by hurricane band 216, and prevents or reduce the stagnation along inner reservoir wall.Along the inner reservoir wall 229 adjacent with hurricane band 216 gel-forming thus substantially reduce.

In an example, agitator 214 comprise relative to one or more mixed columns 218 from hurricane band 216 to inner position (such as, the interval that mixed column 218 leaves inner reservoir wall 229 comprises, but be not limited to, 5cm or less, or about 6cm, 7,8,9,10,11,12,13,14,15,16,17,18,19cm or about 20cm or larger, and optionally correspond to the width of hurricane band 216).Multiple mixed column 218 comprises, and such as, extends to the tapered pole of agitator ring 220 from outlet opening 208.Polymer fluid mixes by mixed column 218 in the interior section of melt pool 224, such as, relative to hurricane band 216 and inner reservoir wall 229 away from.In other words, mixed column 218 orientate as with inner reservoir wall 229 away from, and the mixing of polymer fluid in melt pool 224 inside primarily of mixed column 218 (with also shown in figure 2 one or more optionally to corner post 219) provide, polymer fluid is undertaken along wiping of inner reservoir wall 229 by hurricane band 216 simultaneously.

As further shown in Figure 2, in an example, agitator 214 comprises one or more baffle plate 222.Baffle plate 222 is perforation, such as, with the flowing allowing polymer fluid to pass through it, towards outlet opening 208.In another example, baffle plate 222 comprises provides overhead gage that is downward and that move upward and lower baffle plate (lower baffle plate is blocked by the agitator ring 220 shown in Fig. 2 at least in part) to polymer fluid respectively, is therefore vertically mixed in finisher container 204 by polymer fluid.

Referring again to the agitator 214 shown in Fig. 2, in an example, agitator 214 comprises agitator ring 220.As shown, agitator ring 220 is connected with one or more in mixed column 218 or hurricane band 216.Hurricane band 216 can comprise the periphery closely adjacent with inner reservoir wall 229 (such as, outward flange) (such as, within the about 1.3cm of wall, or within the about 0.6cm of wall, as at about 0.000 of wall, within 1cm to about 1.3cm or about 0.6cm, as at about 0.000 of wall, within 1cm or less, or leave wall about 0.000,5cm, 0.001,0.005,0.01,0.05,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1,1.1,1.2 or about 1.3cm or larger).One or more in agitator ring 220 pairs of mixed columns 218, hurricane band 216 and baffle plate 222 provide support body, and are therefore remained in shown arrangement by these parts.Additionally, polymer fluid optionally mixes by agitator ring 220.Agitator ring 220, in an example, the surface (one or more such as, in inner or outer surface) along ring comprises one or more groove, breach, blade etc., to strengthen the mixing provided by agitator 214.

In shown example, agitator ring 220 is remotely located (such as, outward flange 216 closely adjacent of opposed helical band) relative to inner reservoir wall 229.In other words, outward flange 216 to the wall 229 of opposed helical band closely adjacent, provides gap between agitator ring 220 and wall 229.Optionally, the interval of agitator ring 220 and inner reservoir wall 229 includes, but not limited to 5cm or lower, or about 6cm, 7,8,9,10,11,12,13,14,15,16,17,18,19cm or about 20cm or higher, and optionally correspond to the width of hurricane band 216.Therefore, along with agitator 214 rotates in finisher assembly 200, such as by rotation in melt pool 224, agitator ring 220 is separated from inner reservoir wall 229 with along the gel that inner reservoir wall 229 forms (such as, relative with agitator ring 220) formation.By moving inward agitator ring 220, such as, by making its interval away from inner reservoir wall 229, even if having the generation of gel along inner reservoir wall 229, agitator ring 220 relative gel is remotely located, and between ring and gel, any mechanical engagement reduces substantially.Therefore, gel is reduced similarly by shifting out of joint.

In a similar manner, and as described herein, mixed column 218 is located away from inner reservoir wall 229.In other words, relative to the outward flange 216 of hurricane band and the closely adjacent of inner reservoir wall 229, between mixed column 218 and inner reservoir wall 229, gap is provided.Such as, the interval of mixed column 218 and inner reservoir wall 229 comprises, but be not limited to, 5cm or less, or about 6cm, 7,8,9,10,11,12,13,14,15,16,17,18,19cm or about 20cm or more greatly and optionally correspond to the width of hurricane band 216.When polymer gel is along one or more formation in mixed column 218, gel location is away from inner reservoir wall 229.Therefore, the gel non-involvement chamber wall 229 on mixed column 218, and do not shift out similarly.In other words, even if when finisher assembly 200 produces gel along inner reservoir wall 229, substantially prevent with the finisher assembly 200 comprising agitator 214 (there is the agitator ring 220 and mixed column 218 of remotely locating) shown in Fig. 2 otherwise by least with inner reservoir wall 229 to a certain degree tight any mechanical engagement of providing of the agitator ring 220 (or mixed column 218) of adjacent positioned.In the running of finisher assembly 200 (such as, period is as more than 91 days for a long time), gel does not shift out from inner reservoir wall 229 by the agitator ring 220 of remotely locating, and inner reservoir wall 229 correspondingly engages with the gel formed along agitator ring 220 or mixed column 218 and shifted out.

As described before this paper, the generation of finisher assembly 200 inner gel can cause blocking and the generation of other polymer of even lower level when gel shifts out.With the configuration shown in Fig. 2, one or more with in the mixed column 218 separated with inner reservoir wall 229 and agitator ring 220, the joint of the polymer gel formed and shift out a large amount of minimizing.During the finisher assembly 200 comprising agitator 214 is configured to run and substantially extends (more than 91 days) do not having to promote the manufacture of high-quality (HMW) polymer in the time course blocked.

As further shown in Figure 2, in an example, vent condenser 226 is connected to finisher container 204 by the pipe bend extending to vent condenser 226 in the end of elbow.In an example, vent condenser 226 comprises vacuum ejector or vacuum generation system, and it is configured to extract the air in finisher container 204 out, as wherein moist (with steam) air.In another example, steam is supplied to vent condenser 226, such as, there is required moisture content, thus regulate the amount of the moisture extracted out from the atmosphere (such as, the steam 230 of separation) of finisher container 204 by vent condenser 226.Such as, the supplementing water vapor line that flows through of " removal " or supplementing water steam is fed to vent condenser 226.Supplementing water steam is reduced respectively or increases, thus more or less steam is extracted out for the steam 230 be separated in finisher container 204.In other words, by being reduced to the supplementing water steam of vent condenser 226, producing the drier stream of the air under negative pressure, thus taking out other steam from finisher container 204.On the contrary, by being increased to the supplementing water steam of vent condenser 226, producing the humidity stream of air, taking out less steam from finisher container 206.By regulating supplementing water steam to the injection in vent condenser 226, control the amount of the steam 230 of the separation of taking out from finisher container 204.Thus, correspondingly Control platform, the molecular weight of the polymer fluid 228 be such as separated.

In addition, vent condenser 226 comprises condenser system, and described condenser system comprises weir, such as, is arranged on the annular weir in the inner circumferential of vent condenser.Weir is filled with the stream of the water of cooling, and it overflows the sidepiece on weir and is injected in the remaining part of vent condenser 226.Cooling water (relative to be separated steam 230 there is lower temperature) flowing thus by water from be separated steam 230 condensation go out and moisture removed from finisher container 204.Removing moisture allows the polymer fluid 228 of separation to increase its molecular weight along with the polymerization continued, and this corresponds to the increase on Polymer relative viscosity.In another example, provide and cross over vent condenser 226 as crossed over one or more injections of the water on weir, to promote that steam is from the condensation the atmosphere in finisher container 204 further.

Fig. 3 example finisher nozzle 202, another parts of finisher assembly 200.Condensation kettle nozzle 202 is given and extends in finisher container 204 in fig. 2, the back.Fig. 3 is the partial cross section of finisher nozzle 202.Cut open along its center line by the cylinder 303 of nozzle, simultaneously separator spiral 306 wherein provides in side view.Cylindrical tube 303 extends to outlet opening 302 from ingate 300.Cylinder 303 has the cylinder inner circumferential 304 limited from its inner chamber extended through.As shown in Figure 3, cylinder 303 has the internal area 307 (described below, the sectional area perpendicular to the cylinder that helical axis 308 is measured) of substantial constant between ingate 300 and outlet opening 302.In other words, cylinder 303 between ingate 300 and outlet opening 302 be substantially first-class greatly.In an example, according to the demand of the specific finisher nozzle for using together with the finisher assembly 200 shown in Fig. 2, a part for finisher nozzle 202, such as adjacent with outlet opening 302 or adjacent with ingate 300 part, short tapered girth can be had, as having the short taper profile section of diameter instead of monotone variation on short axial length.As shown in Figure 3, cylinder inner circumferential 304 and internal area 307 are substantial constant in the length corresponding to separator spiral 306, as further described herein.

As will be described herein, etc. large cylinder 303 (such as, there is the internal area 307 of substantial constant cylinder inner circumferential 304 and substantial constant) cooperate with separator spiral 306 (illustrating herein) mixed flow with isolating polymer fluid and steam, and therefore the polymer fluid 228 of separation is delivered to finisher container 204 with the steam 230 be separated.Steam 230 reentrainment that finisher nozzle 202 prevents polymer separated substantially, thus substantially prevent the splashing of the polymer be separated accordingly, otherwise its separated steam is along inner reservoir wall 229 reentrainment (as described herein) of the finisher container 204 shown in Fig. 2.

With reference now to Fig. 3, separator spiral 306 is shown as and extends through cylinder 303 at least partially.As shown, separator spiral 306 comprises and as shown extremely holds with end the multiple spiral sections 310 be connected in series.The spiral section 310 of any suitable number can be comprised in separator spiral 306.In example in figure 3, the separator substrate 312 with substantially straight structure is connected with adjacent spiral section 310.Remaining part towards the spiral section 310 of outlet opening 302 extension has the structure of distortion and cooperates to be separated with steam by polymer fluid, thus so that the polymer fluid 228 of separation is delivered to finisher container 204, such as when do not splash inner reservoir wall 229.

In an example, each spiral section 310 comprises the first and second ends 314,316.Each spiral section 310 in a spiral manner (such as, distortion) extends to the second end 316 from first end 314.As previously described, separator spiral 306 and section 310 thereof are shown in side view (not cutting open); Therefore, first end 314 is substantially perpendicular to the page and illustrates, the second end 316 is parallel to the page simultaneously.The remaining part therefore distortion between these ends 314,316 of each section 310.In example in figure 3, each spiral section 310 is from first end 314 to about 90 degree adjacent of the second end 316 distortion.Such as, the outward flange 305 along the top (as shown in Figure 3) of spiral section 310 extends to first end 314 from the second end 316 along with outward flange 305 and little by little extends into the page.On the contrary, the outward flange 305 along the bottom (as shown in Figure 3) of spiral section 310 extends to first end 314 along with edge from the second end 316 and is little by little extended the page.

In another example, adjacent spiral section 310, such as, when starting in ingate 300, Next spiral section 310 on the line towards outlet opening 302, comprises the first end 314 with adjacent second end 316 of previous spiral section 310 not about 90 degree of homophase.Therefore, separator spiral 306 in example shown in Fig. 3 provides the fracture of spiral section 310 (discontinuous) chain, described spiral section provides the helical surface of distortion (such as separately, clockwise or counterclockwise twists in a same direction), it matches with about 90 degree relative to each other at their end.In other words, the second end 316 of spiral section 310 and first end 314 not about 90 degree of the homophase of last spiral section 310.Optionally, spiral section 310 is by including, but are not limited to, and one or more mechanisms of welding, mechanical interworking etc. are paired with each other.

As illustrated further in Fig. 3, in an example, separator spiral 306 connects at one or more sections of anchors 318 place, thus by the remaining part (outward flange 305 of each section 310 such as, as extended along girth 304) of separator spiral 306 and cylinder inner circumferential 304 interval.As further described herein, interval (as gap or separator space 320) between each spiral section 310 and cylinder inner circumferential 304 cooperate the relative separation of sending along helical axis 308 of the steam 230 that is separated as shown in Figure 2 with the steam being provided for being separated polymer 228 the path of advancing isolator (such as, Part I can flow near barrel, and Part II can flow close to middle or core).In example in figure 3, each spiral section 310 is connected with cylinder inner circumferential 304 at the second end 316 (or optionally at the mid portion of first end 314 or section 310) by section anchor 318 separately.According to the interval provided by section anchor 318 (or gap), for separating of the path of steam 230 the separator space 320 provided between inner circumferential 304 and outward flange 305 is provided.

In an example, section anchor 318 is connected by one or more mechanism with cylinder inner circumferential 304, includes, but are not limited to, interference engagement, machinery cooperation, adhesive, prewelding etc.As shown in Figure 3, in an example, section anchor 318 is arranged along a line, such as parallel with helical axis 308 and line that is that extend along cylinder inner circumferential 304.Section anchor 318 to provide for welding element along the setting of this line and is easy to connect with each of the section of reaching anchor 318, and therefore easily each with spiral section 310 of section anchor 318 is connected with cylinder inner circumferential 304.As illustrated further in Fig. 3, in an example, plate anchor 322 is provided for separator substrate 312.In shown example, plate anchor 322 is corresponding with section anchor 318 substantial linear of each of spiral section 310.Therefore, the connection of each and plate anchor 322 of section anchor 318 (such as, welding or coordinate) completes in a linear fashion, such as, with the welding element of either end extending through cylinder 303.

As previously described, each spiral section 310, in an example, respectively with cylinder inner circumferential 304, such as, is connected with section anchor 318.Section anchor 318 cooperates so that each spiral section 310 is in place at cylinder 303 internal fixtion.Therefore, finisher nozzle 202 dimension (in process (such as, after its removal condensation kettle nozzle 202 for clean or in the online clean process of finisher nozzle 202), the heating and cooling comprising the nozzle 202 of separator spiral 306 do not make separator spiral 306 bending and are remained in the orientation shown in Fig. 3 by multiple spiral section 310.In other words, section anchor 318 (and optionally, plate anchor 322) cooperation is with each spiral section of grappling in cylinder 303 310 (and optionally separator substrate 312).In other words, by each spiral section 310 of grappling, thus reduce or prevent the bending of separator spiral 306.Each spiral section 310 firmly grappling of separator spiral 306 is in place.When the separator nozzle 202 comprising separator spiral 306 being heated (and cooling afterwards) in cleaning course, separator spiral 306 does not bend in cylinder 303.The configuration of separator spiral 306, such as, with the configuration in separator space 320, thus keeps in the operation lifetime process of finisher nozzle 202, after described operation lifetime process is included in the neutralization of clean operation process.

In operation, polymer fluid and steam mixed flow by the ingate 300 shown in Fig. 3 send (such as, from Fig. 1 before shown in continuous polymerization system 100 in forward part).Such as, the mixed flow of polymer fluid and steam is delivered to the schematic finisher 114 shown in Fig. 1 from flash vessel 112.As shown in Figure 2, the mixed flow of fluid to be delivered in finisher container 204 and the steam 230 mixed flow being separated into separation before sending and the polymer fluid 228 be separated by finisher nozzle 202.

Referring again to Fig. 3, first the mixed flow of polymer fluid is delivered in the ingate 300 of the cylinder 303 of finisher nozzle 202.Mixed flow to be sent and on separator spiral 306 along separator substrate 312.Because etc. large cylinder 303 (such as, the cylinder inner circumferential 304 of substantial constant and the internal area 307 of substantial constant), be delivered through cylinder 303 along with by the mixed flow of polymer and steam, when being sent to outlet opening 302 by fluid, its speed substantially keeps or increases.Optionally, inner circumferential 304, the diameter of such as inner circumferential, reduces relative to previous finisher nozzle, to increase the shearing (and speed) in the mixed flow of polymer and steam further.In an example, compare with the 17.9cm diameter of previous tapered nozzle, finisher nozzle 202 has the internal diameter of 12.7cm.

When mixed flow moves along separator spiral 306, mixed flow engages series helix section 310.As previously described, each spiral section 310 has the shape (comprise, such as, 90 degree of distortions) of distortion.Each spiral section 310, in another example again, (such as, clockwise or counterclockwise) distortion in a same direction.Along with polymer fluid mixed flow along and flow according to each spiral section 310, kept the speed of fluid by the large profile of the consistent grade of cylinder 303.In other words, because cylinder 303 such as is at large (such as, not the comprising the taper expanded to outlet from entrance), the speed of mixed flow keeps along with being delivered in cylinder 303 or increasing, this with reduce when the conical nozzle expanded contrary.Spiral section 310 is by flowing that is separately following or separation mixing: such as allow polymer fluid to advance along helical axis 308, and lower intensive steam moves to the part outside of spiral section 310 and enters in separator space 320 according to its speed kept simultaneously.On the contrary, underspeed (there is the nozzle reduced) along with by steam more lentamente to cylinder inner circumferential 304 guide can correspondingly reduce provided interval.More intensive polymer fluid 228 keeps substantial linear flow and thus be separated from steam 230 along helical axis 308.Because each and cylinder inner circumferential 304 of spiral section 310 are such as separated by section anchor 318, steam can easily be advanced along separator space 320, and thus substantially keeps the interval of itself and polymer fluid.Therefore, send to outlet opening 302 along with by polymer fluid and steam, cooperation that each of spiral section 310 (waits large cylinder 303) with cylinder inner circumferential 304 thus mixed flow is separated into the polymer fluid 228 be separated and the steam 230 be separated.At outlet opening 302 place of finisher nozzle 202, polymer fluid is mainly sent along helical axis 308, and the steam 230 be separated mainly is delivered in finisher container 204 along cylinder inner circumferential 304 (and guiding parallel with helical axis 308 downwards), as shown in Figure 2.

In addition, by separator spiral 306 with etc. large cylinder 303 being separated of combining that (and the separator space 320 kept therebetween) provide the steam of separation guided in separator space 320 and therefore substantially reduce the polymer fluid of advancing along section 310 to the reentrainment in steam.In other words, steam keeps its speed by substantially first-class cylinder 303 greatly and thus is directed to and remains in the separator space 320 away from directed polymer fluid (and along inner circumferential 304).Steam 230 is separated with polymer fluid 228 thus is maintained by passing through and sending to finisher container 204 in nozzle 202.

In addition, with the configuration shown in Fig. 3, guide along with the large cylinder 303 such as the polymer fluid 228 of separation and the steam 230 be separated being passed through and be delivered in finisher container 204, any splashing of polymer fluid is limited to melt pool 224 substantially.As discussed above, by the splashing isolation of inner reservoir wall 229 from the polymer 228 be separated.Steam is more low-density and easilier than polymer disperses to inner reservoir wall 229.Therefore, by preventing the reentrainment of steam interpolymer, reduce the outside splashing to inner reservoir wall 229.In addition, the stream of the steam 230 of separation to be guided and towards melt pool 224 along helical axis 308 substantially.Mobile the large cylinder 303 such as pass through by the lateral velocity component of the steam of the separation of finisher nozzle 202 and reduce (nozzle relative to expanding).Therefore, substantially reduce along the splashing of inner reservoir wall 229 by the steam with the polymer of reentrainment.The polymer 228 (and the steam 230 be separated) be separated guides to melt pool 224 (see Fig. 2) by finisher nozzle 202, and the splashing from finisher nozzle 202 is guided to similarly in melt pool 224.

The flow chart of Fig. 4 display for using polymer finishing device assembly to comprise the method 400 of the finisher assembly 200 of finisher nozzle 202 as shown in Figure 2.In describing method 400, with reference to one or more parts described herein, feature, function etc.In situation easily, with reference to the parts, feature, function etc. with Reference numeral.The Reference numeral provided only is example and is nonexcludability.Such as, the feature, parts, function etc. that describe in method 400 include, but are not limited to, the element of respective belt numeral described herein, corresponding feature (with numeral with without both numerals), and their equivalent.

At 402 places, the mixed flow of steam and polymer fluid is guided through the finisher nozzle 202 that band has the cylinder (such as, cylindrical tube) of substantial constant cylinder inner circumferential 304.As described herein, in an example, cylinder inner circumferential 304 substantial constant between the ingate 300 and outlet opening 302 of cylinder 303.At 404 places, steam is combined with the mixed flow separator spiral 306 of polymer fluid and is separated into the steam 230 be separated and the polymer fluid 228 be separated with the cylinder inner circumferential 304 of substantial constant.In an example, mixed flow separation is comprised: mixed flow is sent along separator spiral 306.The cylinder inner circumferential 304 of substantial constant keeps the speed of mixed flow when being sent from ingate 300 to outlet opening 302 by mixed flow.Steam is separated from mixed flow, and radially outward moves to (such as, by one or more section anchor 318 by weekly interval in spiral section 310 and cylinder) in the separator space 320 formed between each spiral section 310 and cylinder inner circumferential 304.When keeping the speed of mixed flow, steam easily moves to an inner circumferential 304 such as in separator space 320, and the mixed flow (polymer fluid) of remaining part flows dividually along the helical axis 308 of separator spiral 306 simultaneously.

Method 400 can comprise: at 406 places, the polymer fluid 228 of separation is guided to container, in finisher container 204 as shown in Figure 2.Guide the polymer fluid 228 be separated to comprise, at 408 places, the polymer fluid of separation is delivered to the melt pool 224 of the polymer fluid in finisher container 204.In another example, the polymer fluid of separation is guided to finisher container 204 comprise, at 410 places, according to the cylinder 303 of cylinder inner circumferential 304 with substantial constant, the polymer fluid that restriction is separated is to the splashing of melt pool 224 and inner reservoir wall 229 isolated with splashing.In other words, the stream of the steam 230 of separation guides downwardly towards melt pool 224 and therefore reduces the cross stream component of the steam 230 of separation by the cylinder inner circumferential 304 of substantial constant.Therefore any polymer fluid of separative for reentrainment steam 230 is guided in melt pool 224, and not as the situation with the nozzle reduced is towards inner reservoir wall 229.Additionally and as described herein, the cylinder inner circumferential 304 of substantial constant cooperates with separator spiral 306, concept stock comprises its cooperation in such as separator space 320, to be easily separated from polymer by steam, and therefore send the polymer fluid 228 of separation when there is no reentrainment in the steam 230 being separated as shown in Figure 2.The polymer fluid 228 of separation is sent to melt pool 224 when having that substantially reduce or minimized cross stream component along the line consistent with helical axis 308 substantially, itself otherwise the polymer fluid 228 (or polymer fluid of a part) be separated is sent to inner reservoir wall 229.

Several selections for method 400 are as follows.In an example, guide the steam of mixed flow to comprise and steam guided in the separator space 320 between the outward flange at separator spiral 306 and cylinder inner circumferential 304 such as formed by the edge of each of spiral section 310.In another example, the steam 230 that the separator spiral 306 be used in by mixed flow in cylindrical tube 303 is separated into separation comprises with polymer 228 fluid be separated: guided by multiple spiral sections 310 of the polymer fluid of mixed flow along separator spiral 306.The polymer fluid of mixed flow is guided along spiral section 310 and comprises: the multiple spiral section directs polymer fluids connected along the first and second end 314,316 places of each at respective spiral section 310.As described before this paper, in another example, first end 314 and contiguous the second end 316 phase different from each other (such as, with 90 degree).

In another example, restriction is splashed and isolation inner reservoir wall 229 comprises: according to the cylinder inner circumferential 304 of substantial constant, by the steam 230 of separation and the longitudinal axis of the polymer 228 be separated along cylinder 303, such as consistent with the helical axis 308 of separator spiral 306 axial melt pool 224 guides downwards.In another example again, inner reservoir wall 229 and splashing isolation are comprised: according to the cylinder inner circumferential 304 of substantial constant, reduce radial direction (such as, the laterally) component being guided through the steam 230 of the separation of finisher nozzle 202.In other words, by providing the cylinder do not reduced (the cylinder inner circumferential 304 of substantial constant), the steam 230 of separation, the mode replacing outwards expanding is sent, generation for guide to melt pool 224 essentially towards under component send.Therefore, also any polymer fluid of separative for reentrainment steam 230 is down guided in melt pool 224.

In another example, method 400 comprises: stir polymer fluid 228 with finisher agitator 214 as shown in Figure 2.As shown, finisher agitator 214 rotates in finisher container 204.In another example, finisher agitator 214 stirring of the polymer fluid 228 of separation is comprised: polymer fluid hurricane band 216 is wiped along inner reservoir wall 229 in wiping district.The outward flange of hurricane band and inner reservoir wall 229 closely adjacent positioned (such as, in about 0.6cm or about 0.7cm).In another example again, the polymer fluid 228 of separation is stirred with finisher agitator 214 and comprises: polymer fluid hurricane band 216 is wiped along inner reservoir wall 229 in wiping district.

Agitator ring 220 is connected with one or more mixed column 218, and itself and inner reservoir wall 229 are remotely located relative to the hurricane band with the tight adjacent positioned of inner reservoir wall 229.Such as, as shown in Figure 2, agitator ring 220 and described one or more mixed column 218 relative to inner reservoir wall 229 and hurricane band 216 to inner position.Closely adjacent relative to hurricane band 216 and inner reservoir wall, described one or more mixed column 218 and agitator ring 220 separate from inner reservoir wall.Agitator ring 220 is connected with one or more in hurricane band 216 or one or more mixed column 218.The polymer fluid 228 of separation is stirred with finisher agitator 214 and comprises: the polymer fluid of separation is mixed with the one or more mixed columns 218 be connected with hurricane band 216 in the mixed zone away from inner reservoir wall 229.

In another example again, stir the polymer fluid 228 be separated and comprise: inner reservoir wall 229 and agitator ring are isolated.As described herein, in an example, agitator ring 220 is remotely located relative to inner reservoir wall 229.Therefore, in the running of finisher assembly 200, along with gel accumulates along inner reservoir wall 229, agitator ring 220 by not with the gel phase mutual effect formed along wall 229, until far become the run duration of (far along into) finisher assembly 200 (such as, after 90 with the close operation continuously in heaven).Similarly, any gel phase produced along agitator ring 220 is remotely located for inner reservoir wall 229.Therefore, the gel along inner reservoir wall 229 is reduced by the interception of inner reservoir wall 229 by the gel in the interception of agitator ring 220 or agitator ring 220, gel shift out minimizing and gel also reduces to sending accordingly in the cylinder 213 of finisher assembly 200.Obstruction and low-quality polymer product reduce (such as with this arrangement substantially, when finisher nozzle 202 and mixed column 218 and agitator ring 220 are from inner reservoir wall 229 recessed, the splashing reduced), and the service life scope of finisher assembly 200 increased significantly before needs are clean.

In another example again, method 400 also comprises and being cleaned by finisher nozzle 202.Finisher nozzle 202 (such as, cylinder 303 and separator spiral 306) heats by clean comprising.In addition, each warpage not being subject to being caused by heating (and the cooling after heating) in multiple spiral sections 310 of separator spiral 306 suppresses.Suppress to comprise each in multiple spiral section 310 is anchored into an inner circumferential 304.In an example, multiple spiral section 310 is connected having multiple corresponding section anchor 318 when such as (such as, coordinated by electric welding, machinery, interference engagement) connected along cylinder inner circumferential 304 to cylinder inner circumferential 304 respectively.
