Definitions
- the present invention relates to a nozzle block for producing synthetic threads and fibers with a housing which accommodates a nozzle package, the nozzle package having an upper nozzle block part, a support part and a nozzle.
- the nozzle blocks of the known spinning systems have a housing which accommodates a nozzle package.
- the nozzle package generally consists of a nozzle block upper part, a support part and a nozzle, which are arranged one behind the other in the direction of flow.
- AI and DE 33 24 833 AI nozzle blocks which have a nozzle block upper part and a nozzle which are arranged in a cylindrical housing.
- EP 0 931 863 A2 (US-A-5,662,947) describes a nozzle block with a nozzle package of the type specified above.
- a conical ring seal seals the nozzle pack towards the support plate.
- Inside the cone-shaped ring seal there is a displacer body, which is flushed around the outside and has holes on the outer ring as the upper part of the nozzle block.
- the cup-shaped support plate is supported on the plate-shaped nozzle which is inserted into the housing.
- the pot-shaped support plate rests with an outer peripheral edge on the nozzle plate, an annular seal being arranged between the support plate and the nozzle plate within the peripheral edge.
- the upper part of the nozzle block and the support part are clamped against each other with a clamping ring.
- the pot-shaped support plate encloses a cylindrical filter chamber, which is pressurized.
- the melt exerts, as described, a radial force on the ring seal, which is pressed against the circumferential edge as a result of the contact pressure.
- Another disadvantage is that the filter, in particular the filter sand, is difficult to remove from the pot-shaped support part. In many cases, residues remain on the wall of the pot-shaped support part.
- the invention has for its object to provide a nozzle block, the nozzle package seals against the housing when pressurized and in the depressurized state, so that a high product quality is guaranteed.
- the nozzle package of the nozzle block according to the invention is a so-called self-sealing nozzle package, in which the support part is pressed against the nozzle when the filter space is pressurized.
- the nozzle pack is clamped in the housing in such a way that the means for sealing between the support part and the nozzle can be axially pressed when the filter space is pressurized.
- the support part is fundamentally not supported on the nozzle, but only on the sealing means, so that the sealing means are pressed in the axial direction. This ensures that the melt cannot pass through the horizontal gaps between the support plate and nozzle on the one hand and sealant and nozzle on the other.
- the degree of freedom of movement of the support member in the housing is limited by a stop in the nozzle block according to the invention. This stop ensures that excessive deformation of the sealant is excluded.
- a reliable seal is ensured in the nozzle block according to the invention both when the filter chamber is pressurized and in the depressurized state in that the sealing means are pressed between the support part and the nozzle in the axial direction.
- the housing does not come into contact with the product flow and is only used for axially bracing the nozzle assembly. Since the housing does not absorb any radial forces, only small wall thicknesses are required, which in turn results in relatively small housing dimensions.
- the support part has a shoulder which overlaps the nozzle, the stop for the support part being a shoulder on the inside of the housing below the shoulder of the support part. Because the heel of the support member the means for sealing ring-shaped encloses, a kind of chamber is formed that receives the sealant. This chamber prevents the sealant material from flowing under high pressure.
- the shoulder of the support part and the shoulder of the housing are preferably designed such that there is always a defined distance with the interposition of the means for sealing between the support part and nozzle when the filter space is depressurized.
- the distance should be dimensioned so that even after the sealant has been placed, the support part with the shoulder does not rest on the shoulder.
- the nozzle assembly is preferably axially clamped in the housing with a pressure ring which is screwed into the housing.
- a pressure ring which is screwed into the housing.
- the means for sealing are preferably formed by a flat seal arranged between the support part and the nozzle, which surrounds a single or multi-layer filter.
- a so-called edged single or multi-layer filter can also be arranged between the support part and the nozzle.
- Such a filter has one or more sieve layers, which are bordered by an annular seal.
- the seal is advantageously a ring, in particular an aluminum ring with a flat U-shaped or C-shaped cross section, which surrounds the sieve layers.
- the parting line between the upper part of the nozzle block and the supporting part is preferably sealed by an annular seal which sits in a circumferential recess in the upper part of the nozzle block and the supporting part, so that the filter space is free of dead spaces and gaps.
- the upper part of the nozzle head is hood-shaped, the supporting part being a support plate.
- This embodiment has compared to the nozzle packs with a pot-shaped support part the advantage that the introduction and removal of the filters, in particular the filter sand, into the filter space is simplified. When the nozzle pack is removed, the filter cake adhering to the support plate comes loose. When lifting off the upper part of the nozzle block completely and without residue.
- the aim is that a large number of nozzle blocks can be fastened close to one another on a spinning beam. This requires the smallest possible outside diameter of the nozzle block.
- a further preferred embodiment therefore provides that the interchangeable nozzle block is preferably attached to the entire spinning system or spinning beam in the form of a quick-release fastener.
- the closure is located on the upper part of the nozzle block.
- This lock is expediently a bayonet lock. Since the torque for closing or opening the closure is applied from the housing to the upper part of the nozzle head, the upper part of the nozzle head is secured in the housing against rotation.
- Fig. 1 housing and nozzle package of a first embodiment of the
- FIG. 2 shows the nozzle block from FIG. 1 in a sectional illustration
- Fig. 4 shows a second exemplary embodiment of the nozzle block in a sectional view
- Fig. 5 shows a detail B of Figure 4 in an enlarged view.
- FIG. 1 shows a perspective illustration of a first exemplary embodiment of the nozzle block 1.
- the nozzle block 1 has an essentially tubular housing 2 which accommodates a nozzle package 3.
- the housing 2 is constructed according to the so-called top loading principle, i. H. the individual parts described in more detail below, from which the nozzle package 3 is made, are inserted into the housing from above.
- the housing is shown in the use position, in which it is attached to a spinning beam.
- the direction of flow of the product stream is designated by A in FIG.
- the nozzle pack 3 has a nozzle 4, a support plate 5 and an upper part 6 of the nozzle head.
- the nozzle 4 is a circular disk with a plurality of through bores 7, of which only two are shown by way of example in FIG. 1. It is supported with an outer circumferential shoulder 8 on an inner circumferential shoulder 9 on the underside of the housing 2.
- the support plate 5 has a plate-shaped body 10 with a plurality of continuous distributor lines 11, which is provided with an upwardly extending circumferential projection 12 and a lower circumferential projection 13.
- the lower extension 13 has a downwardly projecting horizontal sealing surface 14, which is followed by a further downwardly projecting shoulder 15, which overlaps the support plate 4 (FIG. 3).
- the housing 2 has a shoulder 17.
- the support plate 5 is sealed off from the nozzle 4 with a bordered multi-layer filter 18 which is arranged between the support plate and the nozzle.
- the multi-layer filter 18 has a plurality of sieve layers 19 which are bordered by an aluminum sealing ring 20 which has a flat U-shaped cross section.
- the sealing ring 20 is located in the chamber from the horizontal sealing surface 21 of the Nozzle 4 and the horizontal sealing surface 14 and vertical sealing surface 16 of the support plate 5 is limited.
- a distributor space 22 is formed between the support plate 5 and the nozzle 4, which can have a height of 0.5 to 4 mm. Such a distribution room is generally not necessary.
- the pot-shaped upper part 6 of the nozzle head has a cover part 23 and a cylindrical part 24 with which the upper part of the nozzle head rests on the upper circumferential shoulder 12 of the support plate 5.
- the nozzle block upper part 6 and support plate 5 enclose a cylindrical filter chamber 25.
- the upper part of the nozzle block encloses the filter chamber 25 like a hood, completely and pressure-tight. Since the filter space 25 can be filled with sand, the filter space is also referred to as a sand space. Loose individual filters 26, which rest on the support plate 10, can also be inserted into the sand space, the number of individual filters determining the degree of filtering and thus the pressure difference.
- the parting line 27 between the cylindrical part 24 of the nozzle block upper part 6 and the upper shoulder 12 of the support part 10 is sealed with an annular seal 28.
- the ring seal 28 lies in an annular groove 29 which is formed in the cylindrical part 24 and the shoulder 12. It ends flush with the wall of the sand space 25.
- the cover part 23 of the nozzle block upper part 6 has a central recess 30, which is designed as a receptacle for a bayonet lock, with which the nozzle block 1 is attached overhead to the melt feed of a spinning beam, not shown.
- the polymer is fed to the sand space 25 via a melt line 31, which is located in the center of the recess 30 of the cover part 23.
- a sleeve seal 32 is seated in the melt line 31.
- the clamping of the nozzle pack 3 in the housing 1 is served by a pressure ring 33 which is screwed to the housing 2.
- the pressure ring 33 which is supported on an outer shoulder 34 of the cover part 23 of the nozzle block upper part 6, exerts an axial prestress on the nozzle packet 3, which is sufficient to seal the support plate 5 with the ring seal 20 with respect to the nozzle 4 in the unpressurized state.
- the nozzle block upper part 6 and the support plate 4 have no play in the housing 2.
- the sealing ring 20 between the support plate and the nozzle is pressed only in the axial direction, with a flow of the material due to the chambering of the enclosed filter 18 being prevented.
- the dimensions of the outer shoulder 15 of the support plate 5 and the shoulder 17 of the housing 2 are dimensioned such that a defined gap X remains between the shoulder and shoulder in the depressurized state. When pressure is applied, the gap dimension can decrease until the support plate strikes the housing. This limits the degree of freedom of movement in the axial direction.
- the nozzle block upper part 6 is secured against rotation in the housing 2 with pins 35, 36.
- the polymer passes through the melt line 31 of the nozzle block upper part 6 into the sand space 25, where the polymer is filtered through the filter sand and the loose individual filters 26 before it reaches the distribution space 22 through the distribution bores 11 of the support plate 5.
- the melt enters the nozzle channels 7 of the nozzle 4, so that threads or fibers emerge from the nozzle.
- the filter sand adhering to the support plate 5 detaches from the wall of the filter space 25 without residue.
- the filter sand with the support plate 5 and the nozzle 4 is then removed from the housing 2.
- the nozzle block is assembled in the reverse order.
- Figures 4 and 5 show a second embodiment of the nozzle block.
- This embodiment differs from the exemplary embodiment described with reference to FIGS. 1 to 3 only in that, instead of an enclosed multi-layer filter, a multi-layer filter is arranged together with a separate ring seal between the support plate and the nozzle.
- the parts of the nozzle block from FIGS. 4 and 5 which correspond to those from FIGS. 1 to 3 are provided with the same reference symbols.
- the multilayer filter is identified in FIGS. 4 and 5 by the reference number 37 and the ring seal by the number 38.
- the ring seal 38 which in turn is pressed only in the axial direction, consists of an elastic material and has a rectangular cross section. Otherwise, the two exemplary embodiments do not differ in construction and function.
