Description
L'invention est relative à une pompe de circulation d'un fluide dans une cuve de traitement d'une matière présentant une nature perméable à un fluide notamment mais non exclusivement une cuve de teinture. Elle trouvera son application dans l'industrie textile, et en particulier dans les installations de teinturerie.The invention relates to a pump for circulating a fluid in a tank for treating a material having a nature permeable to a fluid, in particular but not exclusively a dye tank. It will find its application in the textile industry, and in particular in dyeing installations.
Ces installations comprennent généralement une cuve à l'intérieur de laquelle on vient placer la matière à traiter, que l'on vient remplir d'un fluide, par exemple, un liquide de teinture, de fixation, de rinçage, ou de la vapeur. Pour réaliser un traitement homogène de la matière, ce fluide est entraîné en circulation forcée à l'intérieur de la cuve de traitement au moyen d'une pompe de circulation qui est utilisée également pour le remplissage et la vidange de la cuve.These installations generally comprise a tank inside which the material to be treated is placed, which is filled with a fluid, for example, a dyeing, fixing, rinsing liquid or steam. To achieve a uniform treatment of the material, this fluid is driven into forced circulation inside the treatment tank by means of a circulation pump which is also used for filling and emptying the tank.
Ces pompes de circulation équipent à la fois les cuves horizontales et les cuves verticales de traitement.These circulation pumps equip both the horizontal tanks and the vertical treatment tanks.
Elles se présentent généralement sous la forme d'un conduit coaxial à la cuve et placé au fond de celle-ci, dans lequel est disposée une turbine entraînée en rotation à l'aide d'un moteur placé à l'extérieur de la cuve de traitement. Le conduit débouche à l'intérieur du plateau porte-matières, ce plateau supportant les bobines à traiter dans le cas d'une cuve verticale, et un rouleau de tissu supporté par un berceau dans le cas d'une cuve horizontale. L'autre extrémité du conduit est en relation avec l'intérieur de la cuve par un orifice coaxial à la turbine, et avec une canalisation d'introduction ou d'évacuation reliée à un circuit extérieur à la cuve. De plus, cette dernière canalisation débouche généralement d'une manière coaxiale à la turbine.They are generally in the form of a conduit coaxial with the tank and placed at the bottom of the latter, in which is arranged a turbine driven in rotation using a motor placed outside the tank. treatment. The conduit opens out inside the material-holding plate, this plate supporting the coils to be treated in the case of a vertical tank, and a roll of fabric supported by a cradle in the case of a horizontal tank. The other end of the duct is connected to the interior of the tank by an orifice coaxial with the turbine, and with an introduction or evacuation pipe connected to a circuit external to the tank. In addition, the latter pipe generally opens out coaxially with the turbine.
Pour autoriser sélectivement, soit une circulation forcée du fluide à l'intérieur de la cuve, soit une circulation forcée du fluide dans le circuit extérieur à la cuve, la pompe de circulation comporte généralement deux obturateurs coaxiaux, l'obturateur extérieur pouvant fermer l'orifice coaxial de communication du conduit avec l'intérieur de la cuve, l'obturateur intérieur pouvant obturer l'arrivée coaxiale de la canalisation reliée au circuit extérieur, ces deux obturateurs étant commandés d'une manière synchronisée de telle sorte que lorsque l'obturateur extérieur est en position fermée, l'obturateur intérieur se trouve en position ouverte, et vice versa.To selectively authorize either a forced circulation of the fluid inside the tank, or a forced circulation of the fluid in the circuit outside the tank, the circulation pump generally comprises two coaxial shutters, the external shutter being able to close the coaxial orifice for communication of the conduit with the interior of the tank, the internal shutter being able to close the coaxial arrival of the pipe connected to the external circuit, these two shutters being controlled in a synchronized manner so that when the shutter outside is in the closed position, the internal shutter is in the open position, and vice versa.
D'une manière pratique, la réalisation de telles pompes présente certaines difficultés en raison du faible encombrement que l'on dispose pour réaliser la pompe, y compris avec les moyens assurant la manoeuvre des obturateurs. En outre, de telles pompes peuvent présenter une turbine d'injection auxiliaire, montée sur l'arbre de la turbine principale, et logée derrière un profil déviateur dans lequel est injecté le fluide en provenance du vase d'expansion de la cuve. De ce fait, la réalisation de l'obturateur intérieur ainsi que de ses. moyens de manoeuvre présente de grandes difficultés.In practical terms, the production of such pumps presents certain difficulties due to the small size that it is available to realize the pump, including with the means ensuring the operation of the shutters. In addition, such pumps may have an auxiliary injection turbine, mounted on the shaft of the main turbine, and housed behind a diverter profile into which the fluid from the expansion tank of the tank is injected. Therefore, the realization of the internal shutter and its. maneuvering means presents great difficulties.
Par ailleurs, l'obturateur extérieur d'une telle pompe se présente habituellement sous la forme d'une bague coulissant suivant l'axe de la turbine, et nécessite la présence de moyens d'étanchéité.Furthermore, the external shutter of such a pump is usually in the form of a ring sliding along the axis of the turbine, and requires the presence of sealing means.
Or, on a constaté que, dans les différents modes de fonctionnement d'une cuve de traitement pendant lequel l'obturateur extérieur est en position fermée, la pression qui s'applique sur sa face externe est toujours supérieure à celle qui s'applique sur sa face interne. En effet, lorsque la cuve fonctionne en circulation forcée avec le circuit extérieur, il existe toujours une dépression à proximité de la turbine qui permet au fluide de s'écouler soit vers l'intérieur soit vers l'extérieur de la cuve. Mais cette différence de pression n'est pas actuellement totalement utilisée pour assurer l'étanchéité de l'obturateur extérieur.However, it has been found that, in the different operating modes of a treatment tank during which the external shutter is in the closed position, the pressure which applies to its external face is always greater than that which applies to its internal face. In fact, when the tank operates in forced circulation with the external circuit, there is always a vacuum near the turbine which allows the fluid to flow either inwards or outwards from the tank. However, this pressure difference is not currently fully used to seal the external shutter.
L'un des buts de la présente invention est de proposer une pompe de circulation qui pallie aux inconvénients mentionnés précédemment, et qui utilise la différence de pression entre les deux faces de l'obturateur extérieur pour assurer son étanchéité. Pour cela, la surface définie par le siège de l'obturateur sera inclinée vis-à-vis de sa direction de déplacement, de telle sorte que, sous l'effet de la différence de pression, l'obturateur soit naturellement appliqué sur son siège.One of the aims of the present invention is to provide a circulation pump which overcomes the drawbacks mentioned above, and which uses the pressure difference between the two faces of the external shutter to ensure its tightness. For this, the surface defined by the seat of the shutter will be inclined with respect to its direction of movement, so that, under the effect of the pressure difference, the shutter is naturally applied to its seat .
L'invention propose également un mode de réalisation des moyens de manoeuvre de cet obturateur, qui permet d'obtenir une ouverture et une fermeture parfaitement régulière de l'obturateur sur la totalité de sa surface. A cet effet, les moyens de manoeuvre seront reliés à des moyens auxiliaires extérieurs à la cuve, qui assureront la parfait synchronisation de leurs mouvements.The invention also proposes an embodiment of the operating means of this shutter, which makes it possible to obtain a perfectly regular opening and closing of the shutter over its entire surface. To this end, the maneuvering means will be connected to auxiliary means external to the tank, which will ensure perfect synchronization of their movements.
L'invention propose également de fixer les moyens de manoeuvre à l'intérieur de la cuve, directement sur une couronne solidaire du conduit de la pompe, ce qui évite de fixer les moyens de manoeuvre sur le fond de la cuve. En effet, ce fond est soumis à des déformations dues aux changements de température de la cuve au cours des opérations, ces déformations même très faiblesn'étant pas compatibles avec un bon ajustement de l'obturateur sur son siège:The invention also proposes to fix the operating means inside the tank, directly on a crown secured to the pump duct, which avoids fixing the operating means on the bottom of the tank. Indeed, this fund is subject to deformations due to changes in temperature of the tank during operations, these very small deformations not being compatible with a good adjustment of the shutter on its seat:
L'invention propose également de remplacer l'arrivée coaxiale de la canalisation d'évacuation et d'introduction par une ouverture déportée par rapport à l'axe de la turbine, cette ouverture débouchant dans une chambre avec laquelle il n'est plus indispensable d'interposer un obturateur pendant le fonctionnement en circuit fermé sur la cuve.The invention also proposes to replace the coaxial inlet of the evacuation and introduction pipe with an offset opening relative to the axis of the turbine, this opening opening into a chamber with which it is no longer essential to '' interpose a shutter during closed circuit operation on the tank.
D'autres buts et avantages de la présente invention, apparaîtront au cours de la description qui va suivre, qui n'est 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 given for information only and which is not intended to limit it.
La pompe de circulation d'un fluide, destinée à équiper une cuve de traitement d'une matière présentant une nature perméable à un fluide, notamment mais non exclusivement, une cuve de teinture, comprenant un conduit cylindrique dans lequel est disposée une turbine coaxiale au conduit, l'une des extrémités du conduit débouchant à l'intérieur d'un plateau porte-matières, l'autre extrémité étant en communication d'une part avec une canalisation reliée à un circuit extérieur à la cuve, et d'autre part avec l'intérieur de la cuve au niveau d'une ouverture définissant un siège sur lequel vient s'appliquer un obturateur amovible, est caractérisée par le fait que le siège de l'obturateur appartient à une surface conique ou cylindrique coaxiale au conduit et que l'obturateur est mobile suivant une direction parallèle à l'axe de la turbine.The fluid circulation pump, intended to equip a treatment tank with a material having a permeable nature to a fluid, in particular but not exclusively, a dyeing tank, comprising a cylindrical duct in which a turbine is arranged coaxial with conduit, one end of the conduit opening into a material tray, the other end being in communication on the one hand with a pipe connected to a circuit external to the tank, and on the other hand with the interior of the tank at an opening defining a seat on which a removable shutter is applied, is characterized in that the seat of the shutter belongs to a conical or cylindrical surface coaxial with the duct and that the shutter is movable in a direction parallel to the axis of the turbine.
L'invention sera mieux comprise si l'on se réfère à la description ci-dessous ainsi qu'aux dessins en annexe qui en font partie intégrante.The invention will be better understood if reference is made to the description below and to the accompanying drawings which form an integral part thereof.
La figure 1 schématise, en coupe, une cuve autoclave horizontale équipée d'une pompe de circulation selon l'invention.Figure 1 shows schematically, in section, a horizontal autoclave tank equipped with a circulation pump according to the invention.
La figure 2 schématise le fonctionnement des moyens de manoeuvre de l'obturateur de la pompe de circulation.Figure 2 shows schematically the operation of the operating means of the shutter of the circulation pump.
La pompe de circulation selon l'invention est illustrée à la figure 1 dans le cas d'une cuve autoclave horizontale. L'invention est illustrée d'une manière non exclusive dans le cas d'une cuve de traitement horizontale, mais elle peut également trouver son application dans le cas d'une cuve de traitement à axe vertical, elle est alors placée sur le fond de la cuve, généralement dans l'axe de celle-ci habituellement de section circulaire. La pompe de circulation qui va être décrite pourra être facilement adoptée par l'Homme de l'Art afin de pouvoir être utilisée en position verticale.The circulation pump according to the invention is illustrated in FIG. 1 in the case of a horizontal autoclave tank. The invention is illustrated in a non-exclusive manner in the case of a horizontal treatment tank, but it can also find its application in the case of a treatment tank with vertical axis, it is then placed on the bottom of the tank, generally in the axis of it usually circular. The circulation pump which will be described can be easily adopted by those skilled in the art so that it can be used in the vertical position.
La cuve de traitement horizontale 1, illustrée à la figure 1, présente un axe longitudinal 2, dont l'une des extrémités est fermée hermétiquement par le couvercle 3, et dont l'autre extrémité est équipée de la pompe de circulation 4, dont l'axe de rotation coin- cide avec l'axe longitudinal 2 de la cuve.The horizontal treatment tank 1, illustrated in FIG. 1, has a longitudinal axis 2, one end of which is hermetically closed by the
A l'intérieur de cette cuve, les matières textiles 5, se présentant par exemple sous la forme d'un rouleau de tissu, sont disposées sur un plateau porte-matières 6, dont le volume intérieur est relié à la pompe de circulation 4. De plus, la cuve 1 présente des canalisations réversibles d'introduction et d'évacuation du fluide, 7 et 8. La canalisation 7 est disposée sur le fond 9 de la cuve, et elle débouche à l'intérieur de la pompe de circulation 4, alors que la canalisation 8 débouche sur la paroi latérale de la cuve en dehors de la pompe, de préférence du côté de celle-ci. Dans la suite, on considèrera que le fluide s'écoule depuis la canalisation d'introduction 7 vers la canalisation d'évacuation 8. Toutefois, une circulation inverse est également possible, et entre dans le cadre du fonctionnement de la pompe de circulation.Inside this tank, the
La cuve de traitement présentera également des moyens de chauffage du fluide, qui ne sont pas représentés à la figure 1, et dont le type et l'agencement seront facilement déterminés par l'Homme de l'Art.The treatment tank will also have means for heating the fluid, which are not shown in FIG. 1, and the type and arrangement of which will be easily determined by those skilled in the art.
La pompe de circulation comprend notamment un arbre 10, coaxial à l'axe 2, sur lequel est monté un rotor 11, mobile à l'intérieur d'un conduit cylindrique 12, coaxial à l'axe 2, qui est solidaire d'un stator 13, disposé dans le prolongement du rotor 11, qui définit en combinaison avec celui-ci la turbine 14.The circulation pump notably comprises a
La partie de l'axe 10, extérieure à la cuve de traitement est montée libre en rotation à l'intérieur d'un palier 15, et son extrémité est accouplée sur un moteur non illustré à la figure 1.The part of the
L'extrémité 16 du conduit 12, dirigée vers l'intérieur de la cuve est en relation avec l'intérieur du plateau porte-pièce 6. Par contre, l'autre extrémité 17 du tronçon 12 débouche à l'intérieur de la cuve de traitement par une ouverture 18, coaxiale à l'axe de la turbine. Le volume défini entre l'ouverture 18 et l'extrémité du tronçon 12 définit un volume de révolution 19, délimité latéralement par des parois 20 et 21, dont le profil est adapté pour faciliter l'écoulement du fluide. La paroi 20 est située du côté intérieur de la cuve, alors que la paroi 21 constitue une surface déviatrice à l'intérieur de laquelle sera disposée une turbine auxiliaire d'injection comme cela sera précisé ultérieurement.The
La canalisation d'introduction 7, dont l'axe est par exemple parallèle à l'axe 2, est déportée par rapport à l'axe de la turbine et elle débouche à l'intérieur duvolume de révolution 19.The introduction pipe 7, the axis of which is for example parallel to the axis 2, is offset relative to the axis of the turbine and it opens inside the volume of
L'ouverture coaxiale 18, définit un siège 23 disposé sur les bords des surfaces 20 et 21 sur lequel vient s'appliquer un obturateur 22, également constitué par une surface de révolution d'axe 2.The
Selon l'invention, le siège 23 constitue une surface conique ou cylindrique coaxiale- à la turbine, et l'obturateur 22 est manoeuvré suivant une direction parallèle à l'axe 2. De ce fait, dès qu'il se créera une différence de pression entre les deux faces de l'obturateur, celui-ci étant préalablement en contact avec le siège, ce dernier pourra s'appliquer naturellement sur son siège. Dans un mode préférentiel, l'obturateur 22 sera constitué par une surface tronconique.According to the invention, the
Selon l'invention, l'obturateur 22 sera déplacé sous l'action de vérins 24 placés à l'intérieur de la cuve 1, et disposés suivant une direction parallèle à l'axe 2. Les corps de ces vérins seront fixés directement au conduit de la pompe par l'intermédiaire d'une couronne 25, ajustée sur l'extrémité 17 du conduit 12. Ce mode de réalisation permet un parfait ajustement de la position du clapet vis-à-vis de celle de l'ouverture.According to the invention, the
Pour obtenir un déplacement régulier du clapet, celui-ci sera manoeuvré par un ou plusieurs vérins, dont les axes 25 seront de préférence régulièrement espacés sur une surface cylindrique centrée sur l'axe 2.To obtain regular movement of the valve, it will be operated by one or more jacks, the
Avec cette conception, les vérins de manoeuvre peuvent être utilisés uniquement pour le déplacement de l'obturateur, car, même en l'absence d'efforts, celui-ci restera appliqué sur l'ouverture 18. En outre, la position inclinée de l'obturateur permet de diminuer les efforts de frottement au moment du relevage del'obturateur.With this design, the actuating cylinders can be used only for moving the shutter, because, even in the absence of effort, it will remain applied to the
La canalisation d'introduction n'étant plus dans l'axe de la turbine, il n'est plus nécessaire de placer un obturateur sur celle-ci., même lorsque la cuve fonctionne en circuit fermé. Les phénomènes de tourbillons qui pourront se produire à l'entrée de cette canalisation n'auront pas de conséquences notables sur le fonctionnement et le rendement de la pompe de circulation.The introduction pipe no longer being in the axis of the turbine, it is no longer necessary to place a shutter thereon, even when the tank operates in a closed circuit. The vortex phenomena that may occur at the entrance to this pipeline will not have significant consequences on the operation and performance of the circulation pump.
Pour s'assurer d'une parfaite synchronisation du déplacement des tiges des vérins 24, solidaires de l'obturateur 22, ces vérins de manoeuvre seront reliés à des vérins auxiliaires 26, comme le schématise la figure 2. Celle-ci illustre d'une manière non limitative le cas de trois vérins.To ensure perfect synchronization of the displacement of the rods of the
Plus précisément, les vérins de manoeuvre 24 sont constitués par des vérins hydrauliques dont le fluide est constitué par de l'eau pour des raisons évidentes de non salissure à l'intérieur de la cuve. Chaque vérin 24 comprend deux chambres 27 et 28 séparées par un piston 29, relié à l'obturateur 22 au moyen de la tige 30. Chacune des chambres 27 est en communication avec l'une des chambres 31 appartenant au vérin auxiliaire correspondant. Les secondes chambres 28 des vérins de manoeuvre 24 sont en communication avec un organe de commande 34, relié à une alimentation en fluide, par exemple, de l'air comprimé.More specifically, the actuating
De leur côté, les secondes chambres 36 des vérins auxiliaires 26 sont reliées ensembles à un second organe de commande 38 relié à une alimentation en fluide par exemple de l'air comprimé.For their part, the
Selon l'invention, les corps fixes des vérins auxiliaires 26 sont reliés à un élément commun 41 et leurs côtés tiges 42 sont également reliés à un élément commun 43 de façon à ne pouvoir réaliser qu'un déplacement rigoureusement synchronisé de ces vérins auxiliaires.According to the invention, the fixed bodies of the
Si l'on introduit de l'air dans l'organe 38, cela se traduit par un déplacement de la surface de séparation air/eau qui transforme la diminution du volume del'eau en trois augmentations rigoureusement égales du volume des chambres 26, 26a et 26b. A leur tour, ces trois augmentations de volume se traduisent par trois diminutions rigoureusement identiques des volumes des chambres 31, 31a et 31b, qui se transmettent par un déplacement correspondant des pistons 29, 29a et 29b.If air is introduced into the
Par ailleurs, lorsqu'on introduit de l'air dans l'organe 34, cela se traduit par un déplacement de la surface de séparation air/eau qui se transmet forcément au niveau des vérins 24 en trois augmentations égales. des chambres 28, étant donnée l'action des vérins auxiliaires 26.Furthermore, when air is introduced into the
Ce circuit hydraulique permet de réaliser une parfaite synchronisation du mouvement des tiges des vérins manoeuvrant l'obturateur 22.This hydraulic circuit allows a perfect syn chronization of the movement of the rods of the actuators operating the
Dans le mode préférentiel illustré à la figure 1, la cuve horizontale présente une canalisation 44 en retour du compartiment d'expansion 45, situé à l'intérieur de la cuve. Cette canalisation 44 débouche sous la surface déviatrice 21 par un orifice 46 situé à proximité d'une turbine auxiliaire 47, montée sur l'arbre 10, qui assure l'injection vers la turbine principale 14 du fluide en provenance du compartiment d'expansion.In the preferred mode illustrated in Figure 1, the horizontal tank has a
La circulation du fluide recueilli dans le compartiment d'expansion permet d'équilibrerles températures et les concentrations du fluide entre la cuve principale et le compartiment d'expansion. Lorsque les températures ne sont pas égales, il apparaît des dilatations différentielles au sein de la cuve et la variation de concentration peut se traduire par des différences de nuances et des taches sur les matières traitées.The circulation of the fluid collected in the expansion compartment makes it possible to balance the temperatures and the concentrations of the fluid between the main tank and the expansion compartment. When the temperatures are not equal, differential expansions appear within the tank and the variation in concentration can result in differences in shades and stains on the materials treated.
