Description
Dispositif de projection régulière de jets d'eau s'appliquant notamment à une installation de liage de non tissésDevice for regularly spraying water jets, particularly applicable to a non-woven binding installation
La présente invention se rapporte aux dispositifs de projection de jets d'eau, utiles notamment pour le liage hydraulique de fibres en des non-tissés mais aussi de matière en feuille telle que des complexes textiles, des films, du papier, des tissus et des tricots. Ce liage consiste à envoyer un rideau de jets d'eau sous pression sur une nappe de fibres, pour les enchevêtrer et les former en une nappe cohérente, sans nécessiter l'utilisation de liant. Les injecteurs utilisés de nos jours et qui concrètement peuvent être réalisés conformément aux enseignements de la figure 3 de la demande de brevet internationale PCT/FR00/01398 et des passages correspondants de la description de ce document.The present invention relates to devices for spraying water jets, useful in particular for the hydraulic bonding of fibers in nonwovens but also of sheet material such as textile complexes, films, paper, fabrics and knitwear. This binding consists of sending a curtain of pressurized water jets onto a sheet of fibers, to entangle them and form them into a coherent sheet, without requiring the use of a binder. The injectors used today and which in practice can be produced in accordance with the teachings of FIG. 3 of the international patent application PCT / FR00 / 01398 and corresponding passages of the description of this document.
D'une manière générale, les injecteurs se composent d'un corps permettant de résister aux contraintes exercées par la pression de l'eau, à la partie supérieure duquel est réalisée une chambre intérieure en général de forme cylindrique alimentée en eau sous pression par une tuyauterie et une pompe.In general, the injectors consist of a body making it possible to resist the stresses exerted by the pressure of the water, at the upper part of which is produced an interior chamber generally of cylindrical shape supplied with water under pressure by a piping and a pump.
A l'intérieur de la chambre est disposée une cartouche constituée par exemple par un tube en tôle perforée recouvert dans sa partie interne par un tissus métallique en acier inoxydable et assurant la fonction de média filtrant.Inside the chamber is arranged a cartridge constituted for example by a perforated sheet metal tube covered in its internal part by a metallic fabric in stainless steel and ensuring the function of filtering medium.
A la partie inférieure du corps est appliquée une plaque perforée de micro-perforations dont le diamètre peut être compris entre 50 et 500 microns et de préférence entre 100 et 200 microns permettant de former des jets ou aiguilles d'eau.A perforated plate of micro-perforations is applied to the lower part of the body, the diameter of which can be between 50 and 500 microns and preferably between 100 and 200 microns, making it possible to form jets or needles of water.
La distribution de l'eau depuis la chambre du corps jusqu'à la plaque perforée peut être réalisée par l'intermédiaire de perçages cylindriques puis coniques complétés par une chambre inférieure de répartition comme cela est décrit à la figure 1 de la demande internationale PCT/FROO/0139.The distribution of water from the chamber of the body to the perforated plate can be achieved by means of cylindrical and then conical bores supplemented by a lower distribution chamber as described in FIG. 1 of the international PCT application / Froo / 0139.
La distribution de l'eau depuis la chambre du corps jusqu'à la plaque perforée peut aussi être réalisée par l'intermédiaire d'un canal étroit s'étendant sur toute la longueur du corps comme cela est décrit à la figure 3 de la demande internationale PCT/FR00/0139. Cette seconde solution technique est nettement supérieure à la première en terme d'homogénéité de l'écoulement de l'eau, et particulièrement à des pressions élevées correspondant à des vitesses d'eau élevées.The distribution of water from the chamber of the body to the perforated plate can also be carried out by means of a narrow channel extending over the entire length of the body as described in FIG. 3 of the application. PCT / FR00 / 0139. This second technical solution is clearly superior to the first in terms of homogeneity of the water flow, and particularly at high pressures. corresponding to high water velocities.
Cette seconde solution présente néanmoins l'inconvénient de nécessiter une grande quantité de matières dans le corps au-dessus de la chambre pour obtenir la résistance mécanique du corps lorsque celui-ci est soumis à la pression de l'eau. L'effort sur le bloc principal étant d'autant plus important que le canal entre la chambre et la plaque perforée est long.This second solution nevertheless has the disadvantage of requiring a large amount of material in the body above the chamber to obtain the mechanical strength of the body when the latter is subjected to the pressure of water. The effort on the main block being all the more important as the channel between the chamber and the perforated plate is long.
L'invention vise un dispositif de projection de jets d'eau, qui permet d'obtenir une répartition régulière de l'eau, sans pour autant nécessiter une grande quantité de matière dans le corps. Le dispositif de projection régulière de jets d'eau comprend un corps résistant à la pression et délimitant une chambre intérieure ayant une embouchure d'entrée et des moyens de mise en communication de la chambre, avec passage à travers une plaque ayant au moins une rangée de perforations, avec une ouverture de sortie, ces moyens comprenant, ménagés dans le corps, des trous à section droite de sortie circulaire, débouchant de la chambre dans un canal adjacent à la plaque et dont la plus grande dimension est perpendiculaire à l'axe des trous. Suivant l'invention, la dimension du canal, dite largeur, perpendiculaire à ladite plus grande dimension et non parallèle à l'axe des trous, est inférieure au diamètre de la section droite de sortie des trous, cette largeur représentant notamment de 10 à 90 % du diamètre. Suivant l'invention, les trous sont, à partir de leurs extrémités éloignées de la chambre intérieure donc proches du canal, fendus sur une partie de leur longueur, notamment sur 10 à 50 % de leur longueur, le long de génératrices se trouvant sensiblement dans un plan défini par l'axe du trou et la plus grande dimension du canal.The invention relates to a device for projecting water jets, which makes it possible to obtain a regular distribution of the water, without however requiring a large amount of material in the body. The device for regularly projecting water jets comprises a body resistant to pressure and delimiting an interior chamber having an inlet mouth and means for placing the chamber in communication, with passage through a plate having at least one row of perforations, with an outlet opening, these means comprising, formed in the body, holes with a circular outlet cross-section, emerging from the chamber in a channel adjacent to the plate and the largest dimension of which is perpendicular to the axis Holes. According to the invention, the dimension of the channel, called width, perpendicular to said largest dimension and not parallel to the axis of the holes, is less than the diameter of the straight section of the outlet of the holes, this width representing in particular from 10 to 90 % of the diameter. According to the invention, the holes are, from their ends remote from the interior chamber, therefore close to the channel, split over a part of their length, in particular over 10 to 50% of their length, along generatrices being substantially in a plane defined by the axis of the hole and the largest dimension of the channel.
Cette disposition permet de régulariser davantage la vitesse des jets le long d'au moins une rangée de perforations. La vitesse de l'eau est sensiblement la même d'une perforation à l'autre, on supprime les tourbillons qui se créent sinon dans le canal dans les intervalles entre deux trous. Afin de pouvoir fabriquer facilement un dispositif de projection de jets de ce genre, on peut, suivant un premier mode de réalisation, constituer le corps non seulement en deux parties, à savoir une partie principale et un mors permettant de fixer la plaque perforée, mais en trois parties, en constituant la partie principale en deux sous-parties, en sorte que l'on peut usiner facilement les trous et le canal. Suivant un mode de réalisation particulièrement préféré, le plan de joint des deux sous-parties est parallèle à la surface de coopération du mors avec la partie principale du corps, de sorte que l'on peut fixer les deux sous-parties et le mors par des vis de fixation communes au mors et aux deux sous-parties.This arrangement further regulates the speed of the jets along at least one row of perforations. The speed of the water is roughly the same from one perforation to another, we remove the vortices that are created otherwise in the channel in the intervals between two holes. In order to be able to easily manufacture a device for projecting jets of this kind, it is possible, according to a first embodiment, to constitute the body not only in two parts, namely a main part and a jaw making it possible to fix the perforated plate, but in three parts, constituting the main part in two sub-parts, so that the holes and the channel can be easily machined. According to a particularly preferred embodiment, the joint plane of the two sub-parts is parallel to the surface of cooperation of the jaw with the main part of the body, so that the two sub-parts and the jaw can be fixed by fixing screws common to the jaw and to the two sub-parts.
Suivant un autre mode de réalisation que l'on préfère, le canal est ménagé dans une pièce rapportée, interposée entre la sortie des trous, qui sont dénommés maintenant premiers trous, et la plaque perforée et ayant, en regard des parois du corps définissant les premiers trous, des parois qui définissent des seconds trous respectivement en regard des premiers trous, les extrémités des seconds trous éloignées de la chambre intérieure débouchant dans le canal qui est délimité par des parois de la pièce rapportée et qui est commun à tous les seconds trous. On monte la pièce rapportée en la faisant coulisser dans un logement oblong, ménagé dans le corps et dont la plus grande dimension est parallèle à l'axe de la chambre intérieure. Cette pièce rapportée est munie, sur ses faces en regard du mors et de la partie principale, de joints d'étanchéité annulaires.According to another preferred embodiment, the channel is formed in an insert, interposed between the outlet of the holes, which are now called the first holes, and the perforated plate and having, facing the walls of the body defining the first holes, walls which define second holes respectively opposite the first holes, the ends of the second holes remote from the interior chamber opening into the channel which is delimited by walls of the insert and which is common to all the second holes . The insert is mounted by sliding it in an oblong housing, formed in the body and the largest dimension of which is parallel to the axis of the interior chamber. This insert is provided, on its faces facing the jaw and the main part, with annular seals.
Les trous de section droite de sortie circulaire sont de préférence cylindriques, mais ils peuvent être aussi coniques, voir même elliptiques. Le diamètre des trous est habituellement compris entre 3 et 25 mm et le pas des trous, à savoir la distance entre les axes de deux trous, est habituellement comprise entre 4 et 30 mm. La profondeur des trous est habituellement comprise entre 5 et 100 mm. Le diamètre des seconds trous correspond à celui des premiers trous et le pas des seconds trous correspond au pas des premiers trous. La profondeur des seconds trous est habituellement comprise entre 1 et 50 mm. Le canal a en général une largeur comprise entre 1 et 24 mm et sa hauteur est en général comprise entreThe circular cross-section holes are preferably cylindrical, but they can also be conical, or even elliptical. The diameter of the holes is usually between 3 and 25 mm and the pitch of the holes, namely the distance between the axes of two holes, is usually between 4 and 30 mm. The depth of the holes is usually between 5 and 100 mm. The diameter of the second holes corresponds to that of the first holes and the pitch of the second holes corresponds to the pitch of the first holes. The depth of the second holes is usually between 1 and 50 mm. The channel generally has a width of between 1 and 24 mm and its height is generally between
10 et 100 mm.10 and 100 mm.
Aux dessins annexés, données uniquement à titre d'exemple : la figure 1 est une vue en coupe du mode de réalisation préféré du dispositif de projection de jet d'eau suivant l'invention ; la figure 2 est une vue en coupe longitudinale suivant la ligne II-In the accompanying drawings, given solely by way of example: FIG. 1 is a sectional view of the preferred embodiment of the water jet projection device according to the invention; Figure 2 is a longitudinal sectional view along line II-
11 de la figure 1 ; la figure 3 est une vue en perspective partielle d'une partie du mode de réalisation représentée aux figures 1 et 2 ; et la figure 4 est une vue analogue à la figure 1 d'une variante. En se reportant aux figures 1 et 2, le dispositif de projection de jets suivant l'invention, qui est représenté, comprend un corps parallélépipédique ayant deux grandes faces 2, 3 opposées, deux petites faces 4, 5 opposées et deux faces 6 frontales opposées. Le corps 1 est en acier. Dans le corps 1 est forée une chambre 7 cylindrique oblongue d'axe 8, qui va d'une face 6 frontale à l'autre. Dans les deux faces 6 frontales sont ménagés des raccords non représentés, constituant une entrée communiquant avec une source d'eau sous pression qui n'est pas représentée. Dans la chambre 7, est disposé un filtre 9 cylindrique de même forme que la chambre 7 mais de plus petit diamètre.11 of Figure 1; Figure 3 is a partial perspective view of part of the embodiment shown in Figures 1 and 2; and Figure 4 is a view similar to Figure 1 of a variant. Referring to Figures 1 and 2, the jet projection device according to the invention, which is shown, comprises a body parallelepiped having two large faces 2, 3 opposite, two small faces 4, 5 opposite and two opposite faces 6 opposite. The body 1 is made of steel. In the body 1 is drilled an oblong cylindrical chamber 7 with an axis 8, which goes from one front face 6 to the other. In the two front faces 6 are formed not shown connections, constituting an inlet communicating with a source of pressurized water which is not shown. In the chamber 7, is arranged a cylindrical filter 9 of the same shape as the chamber 7 but of smaller diameter.
La face du corps 5 est constituée d'un mors 10, qui est vissé au reste du corps 1 par des vis 11.The face of the body 5 consists of a jaw 10, which is screwed to the rest of the body 1 by screws 11.
Sur une génératrice de la chambre 7, s'étendent des premiers trous 12, cylindriques de 6 mm de diamètre, séparés les uns des autres par des parties pleines 13 qui permettent de définir ces premiers trous 12. Ces premiers trous ont une profondeur de 10 mm. L'axe des trous est dirigé perpendiculairement aux faces 4 et 5.On a generator of chamber 7, extend first holes 12, cylindrical 6 mm in diameter, separated from each other by solid parts 13 which make it possible to define these first holes 12. These first holes have a depth of 10 mm. The axis of the holes is directed perpendicular to the faces 4 and 5.
Une pièce 14 (fig. 3) oblongue, en métal ou en matière plastique, est montée dans un logement, défini entre le mors 10 et la partie 6 principale du corps, avec interposition de joints 15 et 16 annulaires toriques d'étanchéité, entre les faces de la pièce 14 qui sont en regard des faces du mors 10 et de la partie 6 principale. Dans cette pièce sont ménagés autant de seconds trous 18 qu'il y a de premiers trous 12. Les trous 18 ont le même diamètre et la même profondeur que les trous 12 et sont respectivement en regard de ceux-ci. L'ensemble des trous 18 débouchent dans un canal 19 commun défini par des parois intérieures de la pièce 14. La plus grande dimension de ce canal 19 est parallèle à l'axe 8. Sa largeur, c'est-à-dire sa dimension perpendiculairement à cette plus grande dimension mais non parallèlement à l'axe des trous 12, est inférieure au diamètre de la section droite de sortie des trous 18. En l'espèce, le canal 19 a une largeur de 3 mm. Le canal 19 remonte par des fentes 20 dans les trous 18 sur une profondeur ou longueur de 5 mm, alors que les trous 18 ont une profondeur de 20 mm.An oblong piece 14 (fig. 3), made of metal or plastic, is mounted in a housing, defined between the jaw 10 and the main part 6 of the body, with interposition of O-rings 15 and 16 O-ring seals, between the faces of the part 14 which are opposite the faces of the jaw 10 and the main part 6. In this part, as many second holes 18 are formed as there are first holes 12. The holes 18 have the same diameter and the same depth as the holes 12 and are respectively opposite these. All of the holes 18 open into a common channel 19 defined by internal walls of the part 14. The largest dimension of this channel 19 is parallel to the axis 8. Its width, that is to say its dimension perpendicular to this largest dimension but not parallel to the axis of the holes 12, is less than the diameter of the straight section of the outlet from the holes 18. In this case, the channel 19 has a width of 3 mm. The channel 19 rises through slots 20 in the holes 18 to a depth or length of 5 mm, while the holes 18 have a depth of 20 mm.
Le canal 19 débouche au-dessus d'une plaque 21 perforée dont les perforations ont un diamètre de 120 microns. La plaque perforée est montée coulissante dans le mors 10 par l'intermédiaire d'un joint 22 d'étanchéité annulaire torique. Juste en dessous de la plaque 22 perforée, le mors 10 définit dans la face 5 une sortie 23.The channel 19 opens out above a perforated plate 21 whose perforations have a diameter of 120 microns. The perforated plate is slidably mounted in the jaw 10 by means of an annular O-ring seal 22. Just below the perforated plate 22, the jaw 10 defines in the face 5 an outlet 23.
A la figure 4, on se dispense de la pièce intermédiaire du mode de réalisation de la figure 1 par le fait que la partie principale du corps est constituée de deux sous-parties 24,25 avec interposition entre elles d'un joint 26. Des vis 28 serrent à la fois les deux sous-parties 24,25 l'une contre l'autre et un mors 29 est vissé sur la partie 24. Le plan de joint 33 entre les parties 24 et 25 s'étend parallèlement à la plaque perforée 30 et les trous 31 ainsi que le canal 34 sont usinés dans la sous-partie 24.In Figure 4, we dispense with the intermediate part of the mode of embodiment of FIG. 1 by the fact that the main part of the body consists of two sub-parts 24.25 with interposition between them of a seal 26. Screws 28 tighten both the two sub-parts 24.25 one against the other and a jaw 29 is screwed on the part 24. The joint plane 33 between the parts 24 and 25 extends parallel to the perforated plate 30 and the holes 31 as well as the channel 34 are machined in Subpart 24.
Les jets qui sortent du dispositif suivant l'invention limpides, sans zone blanche, quelle que soit la position du jet le long du dispositif.The jets leaving the device according to the invention clear, without white area, regardless of the position of the jet along the device.
Grâce à cela, on obtient une nappe non-tissée très homogène, dans une installation de liage hydraulique, qui comprend un dispositif de projection de jets d'eau dont les jets sont dirigés en direction de la surface latérale d'un cylindre sur lequel passe une nappe à lier. Thanks to this, a very homogeneous nonwoven web is obtained, in a hydraulic binding installation, which comprises a device for projecting water jets whose jets are directed towards the lateral surface of a cylinder over which passes a tablecloth to bind.
