Description
What the present invention relates to is the spinning manifold of screw extruder, refers to the spinning manifold that melting synthetic filament spins especially.
Such spinning manifold (referring to DE-AS1908207) is made up of a double-walled heating jacket, this chuck is to be used for holding particularly vaporish thermal medium as pressure vessel, and there is the pump chamber with plane parallel heat-transfer area of a upward opening in portion within it, be used for admitting the parts of input melt, as the pump housing, heat-conducting block under measuring pump and the particular case is connected with conducting heat.The heating jacket of spinning manifold is to be contained in the casing and on every side to be incubated.
In existing heating cabinet, the parts of input melt are to be placed on the heating plate of a double-walled, and it can be flat or its cross section is L-or U-shape, and make it into a hollow box body that seals by the heat-conducting filler of putting thereon.The parts of whole input melt can only be packed into from above, and insulant and corresponding filler must be pulled down for this reason.Because machining tolerance and different thermal expansions more or less have the slit between insulant and filler, because the furnace wall effect, uncontrollable heat can run off by this slit.This has just caused the different heating of melt on each spinning station of spinning manifold.
When the parts of melt are imported in this external dismounting or maintenance, on spinning manifold a workbench will be arranged, operating personnel just join and maintenance work at this enterprising luggage.
Just learn that from DE-PS2120600 high or make the room height can be used for lateral blowing district and long filament cooling for the room that reduces spinning equipment, the screw extruder of the device for spinning of spiral shell thick stick extruder, particularly individual layer will be contained in one and be lower than on the layer of spinning manifold.Must increase floor if be convenient to dismounting here for the melt input block of spinning manifold is desired, then being considered is weak point.
The objective of the invention is, create a kind of spinning manifold, in this casing, can keep in repair with dismounting heating from following or side, the parts of input melt for the building height that reduces device for spinning, comprise spinneret assembly, and on spinning manifold, no longer need workbench.
Purpose of the present invention reaches therefrom, be positioned at outside, level, the cross section is formed between the U-shape cavity of heating jacket of U-shape, being used for holding the pump chamber of importing the melt parts is that the spray silk path that is contained in vis-a-vis in the heating jacket is closed, and when having the spinnerets headgear that spinneret assembly is installed in advance by the spinning shaft assembling, this chamber is (reduction building height) or top the dismounting from the side.Workbench above the spinning manifold just can save like this, if people think to do like this.
For simplifying the assembling of spinnerets headgear, in the improvement structure of spinning manifold, a kind of connection chock, particularly link to each other with the spinnerets headgear of admittance spinneret assembly with external screw thread or bayonet socket and with the pump housing be that sealing links, special and the pump housing be threaded connection or with parts of its formation.The connection chock that is used for connecting the spinnerets headgear needn't be dismantled in the inside in spray silk path, if when the pump housing will be dismantled.Or rather the pump housing be connected chock do as a whole, by formed path between the U-of heating jacket shape cavity assembled and/or the dismounting.
In the present invention can also by two mechanically independently heating clamber be combined into heating jacket, the cross section of heating clamber becomes U-shape, and along a horizontal U-shape cavity one flat continuous mating surface is arranged.When the assembling spinning manifold, the parts of input melt are to be placed on the following U-shape cavity of spinning manifold significantly, then these two mechanically independently heating clamber be fixed together mutually and with the melt input block, got rid of the whole space between heat-transfer area so basically.
Last the heating jacket of double-walled has one to be circular basically, irises out the cross section of pump chamber and spinning shaft end in a kind of improvement structure of spinning manifold, and the advantage of this structure of heating jacket outer wall is that it has once very thin wall thickness much of that.
The advantage of this solution that is provided is that the parts of all importing melt all have a well-proportioned and favourable heating, and have avoided vertical boundary seam in the inside of heating jacket and insulating portion.
Explain this invention by additional signal accompanying drawing below.
The spinning manifold that Fig. 1, melting synthetic filament spin, top view;
Fig. 2, along the sectional view of the spinning manifold of the II among Fig. 1-Fig. 1 that the II line is cut;
The sectional view in Fig. 3, the spray silk path that links to each other with the spinnerets headgear of the pump housing;
The outer wall of Fig. 4, heating jacket has been made the partly sectional view of similar Fig. 2 of modification;
The spinning manifold that Fig. 5, part were revised;
Fig. 6, has the identical heating jacket of the Fig. 5 that mechanically gets along well;
Fig. 7, according to the another kind of cross section of spinning manifold of the present invention.
The top view of the spinning manifold sectional view that Fig. 1 is among Fig. 2 to be seen, it has being used for to moulding the spinning appts that polymer carries out the fiber-synthesizing filament molten spinning that several successive is arranged in rows.As the spinning manifold of from Fig. 2, being seen 1, mainly formed by a double-walled heating jacket 2, it is as pressure vessel receivability thermal medium, especially vaporous biphenyl, and be processed into parallel plane heat- transfer area 3,4,5 one and hold the parts of importing melt in the pump chamber 6 of boundary, in order to reduce heat loss, all heating jacket is encased by an iron sheet casing (7).In this casing, fill up asbestos 8 or a kind of other suitable insulating materials, at spinning manifold is to keep in repair and the insulant of this insulating materials as the compression of simple geometric shape spread in the place that must dismantle, and it locally takes out from the iron sheet casing by closed fracture corresponding.Pass iron sheet casing 7 attracts a heating from above melt supply pipe 9, this pipe and melting appartus link to each other as screw extruder or discharging pump.Melt supply pipe 9 passes double-walled heating jacket 2 and links to each other with a rectangular-shaped assign group component, and the branched bottom that comes out from here leads to the pump housing 10 that is close to mutually with vertical direction.Always an arm leads to the suction side of the melt calculating pump 11 that is fixed on the pump housing 10 from this passage in the pump housing 10, and is a pressure channel (Fig. 3) that leads to outlet 12 at least.The spinnerets headgear and this passage that have spinneret assembly 22 are tightly connected.
The heating jacket 2 of spinning manifold 1 all is a double-walled on its whole length according to the present invention, and its cross section is a U-shape, and at this moment two of heating jacket 2 U-shape cavitys 14 are level vertical (Fig. 7) with 15.The path that the inner face 3,4,5 of the U-shape cavity 14,15 of heating jacket open side constitutes pump chambers 6 or extends on the whole length of heating jacket 2 produces heat loss and limits with the thermal conductor of filling piece 16 shapes for fear of the end at it.Pump chamber 6 has held the parts of input melt, as the pump housing 10, and melt metering pump 11 and melt assign group component.Get in order to transfer heat to the parts that will heat better, the parts of input melt are on the heat-transfer area of whole multiple sensing pump chamber 6 at U-shape cavity 15, and compress by other turnbuckle or hold-down bolt.
For going on the base of the pump housing 10, to want the several spray silk of seal welding path 17 in the heating jacket 2 that spinnerets headgear 13 is packed into, for example two spray silk paths 17 are arranged by each pump housing 10 of Fig. 1, promptly from pump chamber 6 come out to penetrate vertically downward double-walled heating jacket 2 below U-shape cavity 15.At this moment the spray silk path 17 that is close to mutually preferably becomes a mutual group part and extends on the whole length of spinning manifold and be solded into heating jacket 2.
For at when assembling dismounting spinnerets headgear 13 better, spinning shaft expansion 18 will be connected with vertical spinning shaft 17.Yet the unillustrated lateral blowing path of drawing downwards is that flange is connected with spinning shaft expansion 18.Spinning shaft expansion 18 also can be used to spinning manifold is supported and is fixed on a workbench or the similar support.
Fig. 3 showed is the detailed sectional view of the spinning shaft 17 in the U-shape cavity that is contained in below the double-walled heating jacket.Also showed a kind of particularly advantageous frame mode in addition, be used for fixing the spinnerets headgear 13 of admitting spinneret assembly 22 and be convenient to the pump housing 10 be packed into and split out pump chamber 6 that this pump chamber is to be between the horizontal U-shape cavity 14,15 of heating jacket 2.On its base, in the scope of each spinning shaft 17, a cylindric space 23 is all arranged from the details pump housing 10.Set bolt 25 around having the connection chock 20 of central melt canal 19 to pass to be distributed in inserts this space 23 hermetically.Melt canal 19 is that the outlet 12 by means of the outlet duct of the pump in the pump housing 10 centers.It is to be noted that especially the end face 24 of the connection chock 20 of Zhiing is recessed slightly downwards, be positioned on the heat-transfer area of following U-shape cavity of heating jacket 2 back of the bearing-surface of the pump housing 10.After pulling down spinnerets headgear 13, the pump housing 10 can split out from pump chamber 6 or pack into and need not assemble at connection chock 20 from spray silk path 17 together with the connection chock 20 that is fixed on the pump housing like this.Around connection chock 20 screw thread 21 is arranged, it can be multi-thread, or bayonet socket, for the dismounting that makes spinnerets headgear 13 is simple and easy quick again.
The spinneret assembly 22 that is contained in the spinnerets headgear 13 is made up of following each several part in the known manner, a spinnerets that is equipped with many spinneret orifices, the melt distribution plate 27 that filter 28 is housed in its cylindric space, and the pad 29 that under the anti-melt pressure that connects chock 20, seals spinneret assembly 22 by the effect of the power of joint cover 33.Between joint cover 33 and melt distribution plate 27, spinneret assembly 22 is to be sealed by the metallic membrane 34 of a support at melt distribution plate 27 places.
In the existing structure of spinning manifold 1, be stressed that especially, although for the purpose of installing must leave annular spaces 36 between spinnerets headgear 13 and spray silk path 17, but, sealed because when extending upward, closed by the pump housing 10 in the space that may exist between the parts not because air circulation or furnace wall effect and loses heat.As other characteristics that will emphasize be, connect on the chock 20 that heating jacket 2 just no longer bears by the caused pulling force of melt pressure because spinnerets headgear 13 is fixed on.This is that tool has an enormous advantage for the wall thickness (pressure vessel) of determining this critical components.
Fig. 4 is the sectional view of spinning manifold 1, yet the outer wall of the heating jacket 2 that radially outward refers in this casing mainly is circumflexion and is made of the section of a pipe that seam is arranged in the vertical in suitable mode.It has certain length, and this length arrives the end of the horizontal pump chamber 6 that the melt input block is installed always and is passed down through the end that heating clamber 2 arrives spray silk path 17.Here the solution of being showed on production technology be easy and in view of the stress that causes by the pressure of heat transfer medium also be very favourable.
To be noted that in order simplifying, in drawing, to have omitted the double-screw bolt that compresses that connects melt input block and pump chamber 6.
What Fig. 5 and Fig. 6 showed is exactly the cross section that is equivalent to the spinning manifold among Fig. 2, yet in this cross section heating jacket 2 by two mechanically independently heating clamber 30 and 31 be combined into, they have two in Fig. 5, a mating surface 32 is arranged in Fig. 6, and whole melt input block just is placed on above it and is fixed when spinning manifold 1 is installed.Heating jacket 2 makes it complete by the U-shape cavity 14 of placing from above and being fixed together then, and it has a L shaped cross section by Fig. 6.The cross section that is equivalent to U-shape in Fig. 5 obtains by thermal conductor 37, this thermal conductor on the whole length of heating jacket 2, extend and with flat mating surface 32 is arranged, the heating clamber 20 and 31 of clamping the melt input block simultaneously is fixed together.
In all structures that Fig. 1 to Fig. 6 exemplified, all have this between the outer U-shape cavity 14,15 of heating jacket 2, can pack into from the side the pump housing 10 and melt metering pump 11 horizontal pump chamber 6 and be contained in spray silk path 17 in the following U-shape cavity 15, be used as common design feature.
What also will mention is, the heating clamber the 30, the 31st of two U-shape cavitys 14,15 is connected with each other, and in view of the heating of heating jacket 2 be of such little moment to understanding the present invention, so just omitted CONSTRUCTED SPECIFICATION in order to simplify.
Fig. 7 has finally showed the cross section based on the spinning manifold 1 of structural principle of the present invention, yet the U-shape cavity the 14, the 15th of heating jacket 2 in this cross section is vertical and be to seal the double-walled heating jacket of packing into vertically downward from the spray silk path 17 that pump seat 6 comes out, preferably welding.At this device middle pump body 10 and melt metering pump 11 pump seat 6 of packing into from above.Yet the upper end in spray silk path 17 is sealed by the pump housing 10 that mainly extends on the whole length of spinning manifold 1, so owing to furnace wall effect air circulation has just been interrupted.The side that the pump housing 10 is discharged at melt has the connection chock 20 of respective numbers, and it is with the common assembly of the pump housing 10 formations or make the force-closed loop-type of dynamic coupling with it and be connected with sealed.Spinnerets headgear 13 is tightened onto and connects chock 20 and get on, so melt power is only by the pump housing 10 with spinnerets headgear 13 is accepted and a heating jacket 2 and a spray silk path 17 are not produced stress.
Polymer melt is to be provided by the melt input pipe 9 that is contained in side at this, and it is embedded in a valve assembly 38 that links to each other with the pump housing 10 or the similar assembly, and passes the vertical U-shape cavity 15 of double-walled heating jacket 2.Doughnut 39 around the melt supply pipe is to be connected with the heating clamber of heating jacket by return 40,41.For example return 41 can be drained the condensate that drops in valve assembly 38 fronts.
