Description

L'invention est relative à une cuve autoclave horizontale de traitement de matières textiles, notamment pour effectuer les opérations de blanchiment et teinture des tissus en rouleaux ou du fil en bobines. L'invention trouvera tout particulièrement son application dans l'industrie textile et en particulier chez les teinturiers.The invention relates to a horizontal autoclave tank for treating textile materials, in particular for carrying out the bleaching and dyeing operations of fabrics in rolls or yarn in spools. The invention will very particularly find its application in the textile industry and in particular in dyers.

Les cuves autoclaves horizontales sont munies d'un couvercle amovible qui doit être fermé hermétiquement. Un porte-matières qui peut recevoir la matière textile à traiter sous forme d'ensouple de tissu ou tricot ou de bobine de fil peut être introduit à l'intérieur de la cuve généralement à l'aide de rails latéraux sur lesquels il roule au moyen de galets dont il est muni.Horizontal autoclave tanks have a removable cover which must be hermetically sealed. A material carrier which can receive the textile material to be treated in the form of a bundle of fabric or knitted fabric or a spool of thread can be introduced inside the tank generally by means of lateral rails on which it rolls by means pebbles with which it is provided.

En général, le couvercle est pivotant et le retrait du porte-matières est opéré en utilisant un chariot de transport mobile qui peut recevoir le porte-matières.In general, the cover is pivotable and the removal of the material carrier is effected using a mobile transport cart which can receive the material carrier.

La cuve autoclave horizontale est munie d'un groupe de circulation incorporé directement dans le fond de la cuve et qui assure la circulation d'un flux de fluide à travers la cuve et en particulier le flux est dirigé de telle sorte qu'il parcourt le coeur de la matière textile à traiter. Ce groupe de circulation est généralement muni d'un cône sur lequel s'adapte l'ensouple supportant la pièce de tissu enroulée. L'ensouple présente une multitude d'orifices sur sa périphérie dans lesquels transite le flux de fluide de traitement qui pénètre ainsi au coeur même du rouleau de tissu ou tricot. Le cône autour duquel s'adapte l'ensouple permet de brancher cette dernière directement sur la pompe de circulation du groupe qui alimente ainsi le volume intérieur de l'ensouple creuse en fluide de traitement.The horizontal autoclave tank is provided with a circulation group incorporated directly into the bottom of the tank and which ensures the circulation of a flow of fluid through the tank and in particular the flow is directed so that it traverses the the heart of the textile material to be treated. This circulation group is generally provided with a cone on which the beam supporting the wound piece of fabric is adapted. The beam has a multitude of orifices on its periphery in which the flow of treatment fluid passes which thus penetrates the very heart of the roll of fabric or knitted fabric. The cone around which the beam adapts makes it possible to connect the latter directly to the group circulation pump which thus supplies the interior volume of the hollow beam with treatment fluid.

La cuve autoclave horizontale comprend également une série de vannes qui permettent l'introduction ou la purge des composants nécessaires pour effectuer l'opération de traitement, ainsi que des soupapes de sécurité nécessaires.The horizontal autoclave tank also includes a series of valves which allow the introduction or purging of the components necessary to carry out the treatment operation, as well as the necessary safety valves.

En outre, l'installation de traitement comprend une cuve d'injection ouverte ou fermée ainsi qu'une pompe d'injection auxiliaire. La cuve autoclave est reliée à la cuve d'injection par l'intermédiaire d'une canalisation équipée d'un robinet de réglage du débit. Ainsi, notamment les ' augmentations de volume du liquide de traitement présent dans la cuve autoclave, en raison d'une hausse de la température, sont absorbées par la cuve d'injection. En outre, le fluide résiduel dans la cuve d'injection est refoulé dans la cuve autoclave horizontale par l'intermédiaire d'une pompe d'injection auxiliaire. Il s'en suit une circulation permanente du fluide entre la cuve d'injection et la cuve autoclave. Dans le cas d'une cuve d'injection ouverte, il est nécessaire de disposer d'une pompe auxiliaire d'injection à haute pression afin de repressuriser le fluide avant son introduction dans la cuve autoclave.In addition, the treatment installation includes an open or closed injection tank and an auxiliary injection pump. The autoclave tank is connected to the injection tank via a pipe fitted with a flow adjustment valve. Thus, in particular the increases in volume of the treatment liquid present in the autoclave tank, due to an increase in temperature, are absorbed by the injection tank. In addition, the residual fluid in the injection tank is discharged into the horizontal autoclave tank by through an auxiliary injection pump. It follows a permanent circulation of the fluid between the injection tank and the autoclave tank. In the case of an open injection tank, it is necessary to have an auxiliary high-pressure injection pump in order to repressurize the fluid before its introduction into the autoclave tank.

1 Il est en effet nécessaire de maintenir la cuve autoclave sous pression afin d'éviter que le fluide de traitement ne puisse se vaporiser notamment au niveau de l'hélice du groupe de circulation par un effet de cavitation. 1 It is indeed necessary to keep the autoclave tank under pressure in order to prevent the treatment fluid from being able to vaporize in particular at the level of the propeller of the circulation unit by a cavitation effect.

Il faut remarquer que la présence d'une cuve d'injection annexe présente de nombreux inconvénients. D'une part, cela nécessite d'utiliser un volume de fluide de traitement supérieur au strict nécessaire/ne serait-ce que pour remplir les canalisations qui relient la cuve autoclave à la cuve d'injection. Par ailleurs, les caractéristiques du fluide de traitement présentes dans la cuve d'injection ne correspondent pas forcément à celles du fluide présent dans la cuve autoclave, en particulier, les températures peuvent être sensiblement différentes et l'épuisement du bain présent dans la cuve d'injection peut être inférieur à celui présent dans la cuve autoclave, par exemple, car le colorant du fluide dans la cuve d'injection n'a peut être pas encore été transféré à la matière textile.It should be noted that the presence of an annex injection tank has many disadvantages. On the one hand, this requires using a volume of treatment fluid greater than what is strictly necessary / if only to fill the pipes which connect the autoclave tank to the injection tank. Furthermore, the characteristics of the treatment fluid present in the injection tank do not necessarily correspond to those of the fluid present in the autoclave tank, in particular, the temperatures can be significantly different and the exhaustion of the bath present in the tank d injection can be less than that present in the autoclave tank, for example, because the dye of the fluid in the injection tank may not have been transferred to the textile material yet.

Par conséquent, le fluide de traitement qui est refoulé dans la cuve autoclave par l'intermédiaire de la pompe d'injection auxiliaire présente des caractéristiques différentes du bain principal présent dans la cuve et, par conséquent, il peut s'en suivre une non-homogénéité locale du bain qui entraînera un défaut de teinture.Consequently, the treatment fluid which is discharged into the autoclave tank via the auxiliary injection pump has different characteristics from the main bath present in the tank and, consequently, a non-consequence local homogeneity of the bath which will cause a defect in dyeing.

Le but principal de la présente invention est de présenter une cuve autoclave horizontale qui soit totalement intégrée, c'est-à-dire qu'elle comprend également la cuve d'injection. De la sorte, la quantité de fluide de traitement est réduite au minimum et l'homogénéité du bain est totale. En outre, le groupe principal de circulation a été jumelé dans un mode préférentiel de réalisation avec le groupe d'injection d'où une plus grande simplicité de réalisation et une économie de moteur.The main object of the present invention is to present a horizontal autoclave tank which is fully integrated, that is to say that it also includes the injection tank. In this way, the quantity of treatment fluid is reduced to a minimum and the homogeneity of the bath is total. In addition, the main circulation group has been combined in a preferred embodiment with the injection group, hence greater simplicity of construction and economy of the engine.

D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre qui n'est cependant donnée qu'à titre indicatif et qui n'a pas pour but de la limiter.Other objects and advantages of the present invention will appear during the description which follows which is however given only for information and which is not intended to limit it.

La cuve autoclave horizontale de traitement de matières textiles, notamment pour effectuer les opérations de blanchiment et de teinture des tissus ou tricots en rouleaux ou du fil en bobines qui comprend un couvercle amovible, un porte-matières présentant un ou plusieurs conduits intérieurs de circulation du fluide de traitement, une pompe de circulation du fluide de traitement dans la cuve, des canalisations de remplissage et de vidange de la cuve, est caractérisée par le fait qu'elle présente une paroi interne dont la hauteur est inférieure à celle de la cuve qui délimite deux compartiments dans la cuve, l'un renfermant la matière textile à traiter qui est rempli de fluide de traitement, l'autre faisant office de vase d'expansion en étant initialement non rempli de liquide de traitement mais qui reçoit le liquide excédentaire passant par-dessus la paroi et issu du premier compartiment de traitement.The horizontal autoclave treatment tank for tex materials tiles, in particular for carrying out the bleaching and dyeing operations of fabrics or knits in rolls or in thread in spools which comprises a removable cover, a material carrier having one or more internal conduits for circulation of the treatment fluid, a circulation pump treatment fluid in the tank, filling and emptying pipes of the tank, is characterized by the fact that it has an internal wall whose height is less than that of the tank which delimits two compartments in the tank, l '' one containing the textile material to be treated which is filled with treatment fluid, the other acting as an expansion tank being initially not filled with treatment liquid but which receives the excess liquid passing over the wall and coming from the first treatment compartment.

L'invention concerne une cuve autoclave horizontale de traitement de matières textiles. Elle permet notamment d'effectuer des opérations de blanchiment ou teinture des tissus ou tricots en rouleaux ou du fil en bobines. Dans l'exemple choisi pour illustrer l'invention, il a été pris un porte-matières ensouple destiné à recevoir du tissu en rouleaux. Toutefois, la transformation du porte-matières pour recevoir les bobines de fil est à la portée de l'Homme de l'Art et a déjà fait l'objet de nombreuses réalisations pour ce type de cuve autoclave horizontale.The invention relates to a horizontal autoclave tank for treating textile materials. It makes it possible in particular to carry out bleaching or dyeing operations on fabrics or knits in rolls or in thread in spools. In the example chosen to illustrate the invention, a beam material holder was taken intended to receive fabric in rolls. However, the transformation of the material holder to receive the spools of thread is within the reach of those skilled in the art and has already been the subject of numerous achievements for this type of horizontal autoclave tank.

La cuve autoclave de traitement 1 telle qu'illustrée à la figure 1 comprend un couvercle 2 amovible qui ferme hermétiquement la cuve 1.The autoclave treatment tank 1 as illustrated in FIG. 1 comprises a removable cover 2 which hermetically closes the tank 1.

La matière 3 à traiter qui, ici, se présente sous la forme d'un rouleau de tissu et disposée sur un porte-matières comprenant notamment une ensouple 4 supportée par un berceau non représenté. Il faut noter, à ce sujet, qu'il est impérieux de fixer solidement les différentes pièces présentes dans la cuve afin que lors de la mise en circulation du fluide de traitement, aucune pièce ne se déplace.The material 3 to be treated which, here, is in the form of a roll of fabric and disposed on a material holder comprising no a beam 4 supported by a cradle not shown. It should be noted, in this regard, that it is imperative to securely fix the various parts present in the tank so that during the circulation of the treatment fluid, no part moves.

L'ensouple 4 présente une périphérie munie de multitude de perforations ou d'un grillage, son extrémité étant bouchée afin qu'en injectant du fluide de traitement à l'intérieur de l'ensouple, ce fluide s'échappe par les orifices périphériques et pénètre dans le rouleau 3 de tissu.The beam 4 has a periphery provided with a multitude of perforations or a grid, its end being blocked so that by injecting treatment fluid inside the beam, this fluid escapes through the peripheral orifices and enters the roll 3 of fabric.

Cette circulation du fluide de traitement est réalisée par une pompe de circulation 5 carénée par un manchon de raccord 6 dans lequel l'ensouple 4 vient se glisser afin que son volume intérieur puisse être alimenté directement en fluide de traitement par la pompe de circulation 5. Cette pompe de circulation 5 aspire du fluide de traitement présent dans la cuve 1 par l'autre extrémité du manchon 6.This circulation of the treatment fluid is carried out by a circulation pump 5 streamlined by a connection sleeve 6 in which the beam 4 comes to slide so that its internal volume can be supplied directly with treatment fluid by the circulation pump 5. This circulation pump 5 draws in treatment fluid present in the tank 1 through the other end of the sleeve 6.

De la sorte, une circulation du fluide de traitement est réalisée conformément aux flèches 7 de la figure 1.In this way, a circulation of the treatment fluid is carried out in accordance with the arrows 7 in FIG. 1.

Le fluide de traitement présent dans la cuve forme un bain 8 dont le niveau supérieur 9 recouvre la matière textile 3 à traiter.The treatment fluid present in the tank forms a bath 8, the upper level 9 of which covers the textile material 3 to be treated.

En outre, la cuve autoclave de traitement 1 comprend des canalisations de remplissage, chauffage, et vidange de la cuve non représentée ainsi que des soupapes de sécurité.In addition, the autoclave treatment tank 1 comprises filling, heating and emptying pipes of the tank, not shown, as well as safety valves.

La cuve de la présente invention présente également une paroi interne 10 dont la hauteur inférieure à celle de la cuve qui délimite deux compartiments dans la cuve autoclave 1, le premier compartiment de traitement 11 renferme la matière textile 3 à traiter et est rempli de fluide 8 de traitement qui forme le bain. L'autre compartiment 12 fait office de vase d'expansion, en étant initialement non rempli de fluide de traitement ou du moins très faiblement, et qui reçoit le liquide excédentaire 13 passant par-dessus la paroi 10 et issu du premier compartiment 11 de traitement.The tank of the present invention also has an internal wall 10 whose height less than that of the tank which delimits two compartments in the autoclave tank 1, the first treatment compartment 11 contains the textile material 3 to be treated and is filled with fluid 8 of treatment that forms the bath. The other compartment 12 acts as an expansion vessel, being initially not filled with treatment fluid or at least very slightly, and which receives the excess liquid 13 passing over the wall 10 and coming from the first treatment compartment 11 .

De par cette conception, la cuve d'injection traditionnelle des installations de traitement à cuve autoclave horizontale a été intégrée. Les débordements de liquide dans le compartiment de traitement 11, qui sont occasionnês·.par une augmentation du volume du fluide par dilatation ou en raison des turbulences de circulation, sont recueillis dans le compartiment d'expansion 12.Thanks to this design, the traditional injection tank of horizontal autoclave treatment facilities has been integrated. Liquid overflows in the treatment compartment 11, which are caused by an increase in the volume of the fluid by expansion or due to circulation turbulence, are collected in the expansion compartment 12.

Par ailleurs, une pompe d'injection 14 qui peut être annexée ou de préférence intégrée à la cuve 1 prélève par l'intermédiaire d'une canalisation d'injection 15 le fluide 16 présent dans le fond du compartiment d'expansion 12 et le réinjecte dans le compartiment de traitement 11.Furthermore, an injection pump 14 which can be annexed or preferably integrated into the tank 1 takes off via an injection pipe 15 the fluid 16 present in the bottom of the expansion compartment 12 and reinjects it into the treatment compartment 11.

De la sorte, outre la circulation générale du fluide dans le compartiment de traitement 11, il est créé une circulation auxiliaire du fluide via le compartiment d'expansion 12. Puisque les deux compartiments 11 et 12 sont placés dans la même enceinte 1 et communiquent, ils sont placés à la même pression statique et donc l'injection du fluide d'un compartiment dans l'autre ne pose aucun problème de recompression intermédiaire.In this way, in addition to the general circulation of the fluid in the treatment compartment 11, an auxiliary circulation of the fluid is created via the expansion compartment 12. Since the two compartments 11 and 12 are placed in the same enclosure 1 and communicate, they are placed at the same static pressure and therefore the injection of the fluid from one compartment into the other poses no problem of intermediate recompression.

Par ailleurs, en raison de la proximité immédiate des deux compartiments qui sont placés dans la même cuve, la température du fluide présent dans le compartiment d'expansion 12 est identique à celle dans le compartiment de traitement 11, de même, en ce qui concerne les caractéristiques d'épuisement de bain et donc l'homogénéité du traitement est parfaite. Un clapet anti-retour 17 sera placé dans la canalisation d'injection 15 afin d'éviter un remplissage du compartiment d'expansion 12 via cette canalisation 15 lorsque la pompe d'injection 14 n'est pas actionnée.Furthermore, due to the immediate proximity of the two compartments which are placed in the same tank, the temperature of the fluid present in the expansion compartment 12 is identical to that in the treatment compartment 11, likewise, as regards the characteristics of bath exhaustion and therefore the homogeneity of the treatment is perfect. A non-return valve 17 will be placed in the injection pipe 15 in order to avoid filling the expansion compartment 12 via this pipe 15 when the injection pump 14 is not actuated.

La figure 2 illustre le mode préférentiel de réalisation qui a été adopté dans la conception combinée de la pompe d'injection 14 et de circulation 5.FIG. 2 illustrates the preferred embodiment which has been adopted in the combined design of the injection pump 14 and of the circulation pump 5.

La pompe de circulation 5 comprend une hélice 18 montée sur un arbre 19 entraîné en rotation par un moteur extérieur non illustré. L'arbre 19 traverse la cuve 1 via un presse-étoupe 20 assurant une parfaite étanchéité. L'hélice 18 est carénée dans un manchon 21, généralement cônique dans lequel s'emboîte l'ensouple 4 du porte-matières. Le manchon 21 est supporté par des nervures 22 qui canalisent et stabilisent le flux de fluide de traitement en circulation dans la cuve 1.The circulation pump 5 comprises a propeller 18 mounted on a shaft 19 driven in rotation by an external motor not shown. The shaft 19 passes through the tank 1 via a cable gland 20 ensuring a perfect seal. The propeller 18 is faired in a sleeve 21, generally conical in which fits the beam 4 of the material carrier. The sleeve 21 is supported by ribs 22 which channel and stabilize the flow of treatment fluid circulating in the tank 1.

Le raccordement de l'ensouple 4 dans le manchon 21 fait que le fluide en sortie de pompe de circulation 5 est canalisé dans-la partie interne de l'ensouple 4 munie d'orifices périphériques par lesquels le fluide ressort en traversant la matière textile 3 à traiter.The connection of the beam 4 in the sleeve 21 causes the fluid at the outlet of the circulation pump 5 to be channeled in the internal part of the beam 4 provided with peripheral orifices through which the fluid exits passing through the textile material 3 treat.

Par ailleurs, un profil déviateur central 23, en forme de tronc de cône à génératrice arrondie est disposé autour de l'arbre 19 d'entraînement. La forme extérieure de ce profil déviateur 23 favorise la circulation du fluide et en particulier l'introduction de ce fluide dans la pompe de circulation 5. Le profil 23 déviateur central qui s'appuie sur la cuve 1 sera, de préférence, creux et sera ouvert à l'une de ses extrémités 24 dirigée vers la pompe de circulation 5. Une hélice 25 sera montée sur l'arbre 19 de telle sorte qu'elle soit enveloppée par le profil déviateur 23. Les pales de l'hélice d'injection 25 sont orientées de telle sorte qu'elle a tendance à refouler le fluide 26 présent dans le profil 23 à l'extérieur de celui-ci et plus particulièrement en direction de la pompe de circulation 5.Furthermore, a central deflecting profile 23, in the form of a truncated cone with rounded generatrix, is arranged around the drive shaft 19. The external shape of this deflecting profile 23 promotes the circulation of the fluid and in particular the introduction of this fluid in the circulation pump 5. The profile 23 central deflector which rests on the tank 1 will preferably be hollow and will be open at one of its ends 24 directed towards the circulation pump 5. A propeller 25 will be mounted on the shaft 19 so that it is enveloped by the deflection profile 23. The blades of the injection propeller 25 are oriented so that it tends to discharge the fluid 26 present in the profile 23 to outside of it and more particularly towards the circulation pump 5.

La canalisation 15 d'injection dont une extrémité trempe dans le fond du compartiment 12 d'expansion, a son autre extrémité 27 débouchant à l'intérieur du profil déviateur 23. Ainsi, l'hélice d'injection 24 provoquera un phénomène d'aspiration dans le profil 23 qui aura pour effet d'injecter du fluide, prélevé dans le compartiment d'expansion 12, dans le compartiment principal de traitement 11.The injection pipe 15, one end of which dips into the bottom of the expansion compartment 12, has its other end 27 opening out inside the deflection profile 23. Thus, the injection propeller 24 will cause a suction phenomenon in profile 23 which will have the effect of injecting fluid, taken from the expansion compartment 12, into the main treatment compartment 11.

Selor le mode préférentiel de réalisation décrit ici, les pompes de circulation et d'injection sont combinées et ne nécessitent qu'un seul moteur d'entraînement.According to the preferred embodiment described here, the circulation and injection pumps are combined and require only one drive motor.

Le chargement ou le déchargement de la cuve autoclave de traitement est illustré aux figures 3 et 4. Le couvercle amovible 2 est muni de moyens de translation tels que des roues 28. En outre, le couvercle 2 est équipé de deux poutres 29 et 30 latérales qui peuvent se translater longitudinalement dans des rails 31 et 32 fixés dans la cuve 1. La translation est assurée, par exemple, grâce à la présence de roulettes 33 à l'extrémité des poutres 29 et 30. Les poutres 29 et 30 servent en outre de supports à deux berceaux transversaux 34 qui, eux-mêmes, servent d'appui à l'ensouple 4.The loading or unloading of the autoclave treatment tank is illustrated in FIGS. 3 and 4. The removable cover 2 is provided with translation means such as wheels 28. In addition, the cover 2 is equipped with two lateral beams 29 and 30 which can be translated longitudinally in rails 31 and 32 fixed in the tank 1. Translation is ensured, for example, thanks to the presence of rollers 33 at the end of the beams 29 and 30. The beams 29 and 30 are also used of supports with two transverse cradles 34 which themselves serve to support the beam 4.

Des moyens de verrouillage seront adoptés pour que, lors de la refermeture de la cuve, le porte-matièreset la matière soient fermement immobilisés à l'intérieur.Locking means will be adopted so that, when the tank is closed, the material holder and the material are firmly immobilized inside.

La canalisation d'injection 15 sera réalisée en deux parties avec un raccord intermédiaire 35 qui permettra d'assurer la jonction entre les deux éléments lors de la fermeture de la cuve.The injection pipe 15 will be made in two parts with an intermediate connector 35 which will ensure the junction between the two elements when the tank is closed.

Le mode préférentiel de réalisation qui a été adopté ici n'a été donné qu'à titre d'exemple et d'autres mises en oeuvre, à la portée de l'Homme de l'Art, auraient pu être envisagées sans pour autant sortir du cadre de celle-ci.The preferred embodiment which has been adopted here has been given only by way of example and other implementations, within the reach of those skilled in the art, could have been envisaged without thereby departing. of the framework of this one.

Une amélioration peut être apportée à la cuve autoclave décrite précédemment en dotant celle-ci de moyens pour.ajuster le niveau supérieur du bain dans le compartiment de traitement. En effet, dans ce dernier cas, il est possible d'optimiser le ratio volume de bain sur volume de matière à traiter, en ajustant la hauteur de la paroi 10 de façon à ce que le niveau supérieur du bain vienne juste couvrir la matière à traiter. Dans ce cas, la teinture est uniforme et la quantité de colorant utilisé est réduite au strict nécessaire.An improvement can be made to the autoclave tank described above by providing the latter with means for adjusting the upper level. of the bath in the treatment compartment. Indeed, in the latter case, it is possible to optimize the ratio of bath volume to volume of material to be treated, by adjusting the height of the wall 10 so that the upper level of the bath just covers the material to be treated. treat. In this case, the dye is uniform and the amount of dye used is reduced to the strict minimum.

Dans la pratique, cela se traduit, par exemple, par un ajustement en hauteur de la paroi 10 qui peut être réalisé en utilisant une paroi fixe et une paroi coulissante par rapport à la première et qui servira au réglage.In practice, this results, for example, in an adjustment in height of the wall 10 which can be achieved by using a fixed wall and a sliding wall relative to the first and which will be used for adjustment.

Il faut d'ailleurs noter que le réglage du niveau du bain peut également être réalisé par l'intermédiaire d'une échancrure pratiquée dans la paroi dont on règle la profondeur au moyen d'une pièce autoclave.It should also be noted that the adjustment of the level of the bath can also be carried out by means of a notch made in the wall, the depth of which is adjusted by means of an autoclave part.

Avec ces dispositifs, le remplissage de la cuve et en particulier du compartiment de traitement sera réalisé de telle sorte que le niveau affleure la paroi 10 sans qu'il y ait remplissage du compartiment vase d'expansion.With these devices, the filling of the tank and in particular of the treatment compartment will be carried out so that the level is flush with the wall 10 without there being filling of the expansion tank compartment.
