Description

La présente invention est relative à une machine perfectionnée pour le traitement liquide (eau, solvants...) ou gazeux (mousse par exemple) de matières textiles et notamment pour le lavage, le blanchiment ou la teinture de matières textiles sous différentes présentations: bourre, rubans de peignée, filés de fibres, fils continus, plats texturés, rétractés, filés de fibre à âme fil continu, tissus ou tricots.The present invention relates to an improved machine for the liquid (water, solvents, etc.) or gaseous (foam, for example) treatment of textile materials and in particular for washing, bleaching or dyeing textile materials in different presentations: fluff , combing ribbons, fiber yarns, continuous yarns, textured, shrunk dishes, fiber yarns with a continuous yarn core, fabrics or knits.

La présente invention est relative à une machine à cuve horizontale. L'on connaît des machines de lavage, blanchiment et teinture de matières textiles à haute température pouvant atteindre 140° C dans lesquelles les traitements sont réalisés par circulation du bain à travers la matière textile statique. La matière textile est alors chargée de façon horizontale dans la machine: empaquetage, bourre, bobines de rubans de peignée, bobines de filés de fibres ou de fils continus empilées, nappe de fils en ensouple, tissus ou tricots en ensouple, c'est-à-dire enroulés autour d'un tube perforé appelé porte-ensouple.The present invention relates to a horizontal tank machine. There are known machines for washing, bleaching and dyeing textile materials at high temperature up to 140 ° C. in which the treatments are carried out by circulation of the bath through the static textile material. The textile material is then loaded horizontally into the machine: packaging, flock, bobbins of combed ribbons, spools of yarns of stacked continuous fibers or yarn, web of warp yarn, fabrics or knitted warp, ie wrapped around a perforated tube called a beam carrier.

Dans ces machines, la mise en pression statique du bain porté à haute température est réalisée suivant plusieurs procédés connus:

  • - circuit du bain extérieur dans un vase d'expansion soit fermé, soit ouvert. Le bain du vase d'expansion est alors généralement repris par une pompe d'injection et de mise en pression statique pour être renvoyé dans l'appareil autoclave, par des canalisations.
In these machines, the static pressure of the bath brought to high temperature is carried out according to several known methods:
  • - circuit of the external bath in an expansion tank either closed or open. The bath of the expansion vessel is then generally taken up by an injection pump and pressurizing static to be returned to the autoclave, by pipes.

Dans le cas où le vase d'expansion est ouvert, il existe un dispositif pour refroidir le bain avant le vase d'expansion en-dessous de 100°C, 80°C par exemple,

  • - expansion du bain à l'intérieur même de l'autoclave, dans un espace situé au-dessus de la matière: dans ce cas le porte-matière est excentré vers le bas pour que la matière étant recouverte par le bain, il subsiste un espace disponible suffisant au-dessus pour l'expansion.
If the expansion tank is open, there is a device to cool the bath before the expansion tank below 100 ° C, 80 ° C for example,
  • - expansion of the bath inside the autoclave, in a space located above the material: in this case the material holder is eccentric down so that the material being covered by the bath, there remains a sufficient space available above for expansion.

Bien que les performances techniques de ces machines soient bonnes, il s'avère nécessaire de les améliorer encore en réduisant dans toute la mesure du possible, le volume du bain de traitement en circulation, tout en évitant le refroidissement systématique du bain, et par voie de conséquence, en réduisant la consommation d'énergie.Although the technical performance of these machines is good, it is necessary to improve them further by reducing as far as possible the volume of the treatment bath in circulation, while avoiding systematic cooling of the bath, and by consequently, by reducing energy consumption.

On a déjà proposé pour ce faire, par exemple dans US-A-3 916 653, une machine de traitement de textiles dont la cuve est à axe horizontal et qui comporte à son extrémité opposée à son couvercle une zone délimitée entre la paroi du fond et une cloison pour servir de zone d'expansion. Dans cette machine, toutefois, la cloison ne permet pas de communication directe entre la cuve de traitement et la zone d'expansion, le passage du fluide entre ladite cuve et la zone d'expansion étant effectué au travers d'un conduit extérieur à la cuve, de sorte qu'une petite partie seulement du bain de traitement circule dans le vase d'expansion d'une part et que la disposition de multiples tuyauteries extérieures à la cuve provoquent d'importantes déperditions de chaleur, d'autre part.To do this, it has already been proposed, for example in US-A-3,916,653, a textile processing machine, the tank of which has a horizontal axis and which has at its end opposite its cover a zone delimited between the bottom wall. and a bulkhead to serve as an expansion area. In this machine, however, the partition does not allow direct communication between the treatment tank and the expansion zone, the passage of the fluid between said tank and the expansion zone being effected through a duct external to the tank, so that only a small part of the treatment bath circulates in the expansion tank on the one hand and that the arrangement of multiple pipes outside the tank cause significant heat loss, on the other hand.

La présente invention s'est en conséquence donnée pour but de concevoir une machine de traitement de matières textiles ou d'autres matières fibreuses ou poreuses, en milieu liquide ou gazeux, tels que lavage, blanchiment et teinture, qui réponde mieux encore aux nécessités de la pratique que les machines du même type proposées dans l'Art Antérieur, en ce qu'elle permet une réduction importante de la consommation d'énergie de ce type de machine, liée à une réduction du volume du bain de traitement en circulation, à son circuit d'expansion, à la régulation de son débit à travers la matière, résultant d'aménagements apportés à ces machines.The present invention has therefore given itself the aim of designing a machine for treating textile materials or other fibrous or porous materials, in a liquid or gaseous medium, such as washing, bleaching and dyeing, which better meets the needs of the practice that machines of the same type proposed in the prior art, in that it allows a significant reduction in the energy consumption of this type of machine, linked to a reduction in the volume of the treatment bath in circulation, to its expansion circuit, regulating its flow through the material, resulting from arrangements made in these machines.

Cet objet est atteint par une machine présentant la combinaison de caractéristiques énoncées dans la Revendication 1.This object is achieved by a machine having the combination of characteristics set out in Claim 1.

L'agencement d'une zone de dilatation dans un caisson délimité par le fond de la machine et une cloison non-étanche qui permet le passage direct de bain de la zone de traitement à la zone de dilation, permet une diminution du rapport de bain et donc des économies d'énergie (un plus petit volume de bain réchauffé), d'eau, de produits de traitement (produits de teinture par exemple) et par conséquent une pollution moindre.The arrangement of an expansion zone in a box delimited by the bottom of the machine and a non-watertight partition which allows the direct passage of bath from the treatment zone to the dilation zone, allows a reduction of the bath ratio and therefore savings in energy (a smaller volume of heated bath), water, treatment products (dye products for example) and therefore less pollution.

Selon un mode de réalisation avantageux de la machine de traitement de la présente invention, l'échangeur de chaleur est monté dans un logement ménagé pour le recevoir dans ladite zone de dilatation, associé aux moyens de mise en communication de la zone de traitement avec la zone de dilatation.According to an advantageous embodiment of the treatment machine of the present invention, the heat exchanger is mounted in a housing arranged to receive it in said expansion zone, associated with the means for bringing the treatment zone into communication with the dilation zone.

Selon une disposition avantageuse de ce mode de réalisation, ledit logement est situé dans la partie de la zone de dilatation qui communique avec la zone de traitement.According to an advantageous arrangement of this embodiment, said housing is located in the part of the expansion zone which communicates with the treatment zone.

Selon une autre disposition avantageuse de ce mode de réalisation, ledit logement est situé dans une partie de ladite zone de dilatation qui n'est pas en communication directe avec la zone de traitement, la liaison entre la zone de traitement et la zone de dilatation étant assurée par une tubulure dont au moins une partie traverse la zone de dilatation et débouche dans ledit logement.According to another advantageous arrangement of this embodiment, said housing is located in a part of said expansion zone which is not in direct communication with the treatment zone, the connection between the treatment zone and the expansion zone being provided by a tube, at least part of which passes through the expansion zone and opens into said housing.

Selon un autre mode de réalisation avantageux de la machine de traitement objet de la présente invention, l'échangeur de chaleur est monté dans une tuyauterie de liaison de la pompe de circulation du fluide de traitement avec la zone de traitement.According to another advantageous embodiment of the treatment machine object of the present invention, the heat exchanger is mounted in a pipe connecting the circulation pump for the treatment fluid with the treatment zone.

Selon encore un autre mode de réalisation avantageux de la machine de traitement objet de la présente invention, celle-ci comprend des moyens d'introduction de quantités contrôlées d'un gaz comprimé dans la zone de traitement et/ou de la zone de dilatation pour l'asservissement, des pressions qui règnent dans lesdites zones et ainsi définir les hauteurs du niveau de bain de traitement dans la zone de dilatation et la zone de traitement, respectivement.According to yet another advantageous embodiment of the treatment machine which is the subject of the present invention, it comprises means for introducing controlled quantities of a compressed gas into the treatment zone and / or the expansion zone for the enslavement, of the pressures which reign in said zones and thus define the heights of the treatment bath level in the expansion zone and the treatment zone, respectively.

Selon un autre mode de réalisation avantageux de la machine conforme à la présente invention, la pompe de circulation du fluide de traitement est une pompe centrifuge permettant la circulation dudit fluide dans une seule direction.According to another advantageous embodiment of the machine according to the present invention, the treatment fluid circulation pump is a centrifugal pump allowing the circulation of said fluid in one direction.

Selon une disposition avantageuse de l'invention, la pompe de circulation du fluide de traitement est une pompe centrifuge équipée d'un organe inverseur pour permettre la circulation dudit fluide alternativement dans deux directions inverses.According to an advantageous arrangement of the invention, the pump for circulation of the treatment fluid is a centrifugal pump equipped with a reversing member to allow the circulation of said fluid alternately in two opposite directions.

Selon une autre disposition avantageuse de l'invention, la pompe de circulation du fluide de traitement est une pompe hélicoïdale qui permet la circulation dudit fluide alternativement dans deux directions inverses.According to another advantageous arrangement of the invention, the treatment fluid circulation pump is a helical pump which allows the circulation of said fluid alternately in two opposite directions.

Selon encore une autre disposition avantageuse de l'invention, la pompe de circulation du fluide de traitement est entraînée par un moteur à vitesse variable.According to yet another advantageous arrangement of the invention, the treatment fluid circulation pump is driven by a variable speed motor.

Selon un mode de réalisation avantageux de ladite cloison, celle-ci est constituée par une paroi métallique interne qui comporte une ouverture axiale propre à recevoir l'extrémité correspondante de la tuyauterie axiale susdite, pour mettre en communication la cuve de traitement avec la pompe de circulation.According to an advantageous embodiment of said partition, the latter is constituted by an internal metal wall which has an axial opening suitable for receiving the corresponding end of the above-mentioned axial piping, for placing the treatment tank in communication with the pump. circulation.

Selon un autre mode de réalisation avantageux de la machine de traitement objet de l'invention, celle-ci est équipée d'un dispositif de réception des porte-matière, situé à l'extrémité intérieure de la tuyauterie axiale susdite et comprenant un socle solidaire de ladite tuyauterie et portant un cône de réception desdits porte-matière.According to another advantageous embodiment of the processing machine object of the invention, it is equipped with a device for receiving material carriers, located at the inner end of the above-mentioned axial piping and comprising an integral base of said piping and carrying a cone for receiving said material carriers.

Selon une disposition avantageuse de ce mode de réalisation, le porte-matière est relié au dispositif de réception par l'intermédiaire d'un dispositif approprié qui permet la mise en place d'un porte-matière à capacité réduite, n'occupant pas la totalité de ladite première zone de la cuve de la machine, à un niveau quelconque dans la machine et notamment le plus bas possible dans cette dernière pour réduire davantage encore le volume du bain.According to an advantageous arrangement of this embodiment, the material carrier is connected to the receiving device by means of an appropriate device which allows the installation of a material carrier with reduced capacity, not occupying the whole of said first zone of the tank of the machine, at any level in the machine and in particular as low as possible in the latter to further reduce the volume of the bath.

Conformément à l'invention, des corps morts sont prévus sur les porte-matière pour occuper les zones mortes situées entre les piles de matière à traiter portées par les porte-matière, réduisant ainsi de façon supplémentaire, le volume intérieur de la machine et, par voie de conséquence, le volume de bain en circulation.In accordance with the invention, dead bodies are provided on the material carriers to occupy the dead zones located between the stacks of material to be treated carried by the material carriers, thereby further reducing the interior volume of the machine and, consequently, the volume of circulating bath.

Selon une disposition avantageuse de ce mode de réalisation, lesdits corps morts sont solidaires des porte-matière.According to an advantageous arrangement of this embodiment, said dead bodies are integral with the material carriers.

Selon une autre disposition avantageuse de ce mode de réalisation, les corps morts prévus entre les porte-matière sont solidaires non pas de ces derniers, mais de la cloison.According to another advantageous arrangement of this embodiment, the dead bodies provided between the material carriers are secured not to the latter, but to the partition.

Cette disposition présente un avantage important dans le cas d'une cloison amovible solidaire des corps morts, attendu que l'on peut mettre en place dans la machine un ensemble solidaire cloison/corps morts pour le traitement de matières sur un type de porte-matière donné et le retirer pour le remplacer par un autre ensemble, également amovible, adapté à des types de porte-matière de dimensions différentes, portant, par exemple, des bobines de diamètre différent de celles susceptibles d'être portées par le type précédent de porte-matière.This arrangement has an important advantage in the case of a removable partition secured to the dead bodies, since it is possible to set up in the machine an integral partition / dead body assembly for the treatment of materials on a type of material carrier given and remove it to replace it with another set, also removable, suitable for types of material holders of different dimensions, carrying, for example, coils of different diameter than those likely to be carried by the previous type of door - material.

Egalement conformément à l'invention, les caissons de répartition du bain de traitement associés d'une manière connue aux porte-matière sont pourvus de perforations qui assurent un retour plus rapide du bain vers le fond de la machine et sa reprise plus rapide résultante par la pompe.Also in accordance with the invention, the distribution bath distribution boxes associated in a known manner with the material carriers are provided with perforations which ensure a faster return of the bath towards the bottom of the machine and its resulting faster recovery by the pump.

This partition 9 delimits, in the autoclave, a first zone, included between the cover 2 and this partition 9, which constitutes the actual treatment tank, 10, and a second zone, defined by this partition 9, the bottom 5 and the corresponding part of the side wall 14 of the autoclave, which constitutes a chamber 13 which encloses the expansion zone of the treatment bath, the first and second zones communicating with the right of the partition 9.

La cloison 9 est percée d'une ouverture sensiblement axiale 15 destinée à recevoir l'une des extrémités d'une tuyauterie 16 d'axe horizontal. Une ouverture 17 latérale est pratiquée dans le fond 5 de la machine. A son autre extrémité, la tuyauterie 16 est reliée à une pompe externe 8 par une tuyauterie 18 et l'ouverture 17 est également reliée à ladite pompe 8 par une tuyauterie, comme décrit plus loin.The partition 9 is pierced with a substantially axial opening 15 intended to receive one of the ends of a pipe 16 with a horizontal axis. A lateral opening 17 is made in the bottom 5 of the machine. At its other end, the pipe 16 is connected to an external pump 8 by a pipe 18 and the opening 17 is also connected to said pump 8 by a pipe, as described below.

Conformément aux modes de réalisations représentés à titre d'exemples non limitatifs aux figures 1, 2 et 8, un échangeur de chaleur 6A, 6D, est monté dans la tuyauterie 19 qui relie l'ouverture latérale 17 pratiquée dans le fond 5 de l'autoclave 1, à la pompe 8. Toutefois, alors que dans les modes de réalisation représentés aux figures 1 et 2, l'échangeur de chaleur 6A est disposé dans la tuyauterie 19, extérieurement à l'autoclave 1, dans le mode de réalisation représenté à la figure 8, l'échangeur de chaleur 6D est logé dans une tuyauterie 35 qui relie la pompe 8 avec la cuve de traitement 10, et plus précisément à l'intérieur de la zone de dilatation 35 qui se trouve à l'intérieur de la zone de dilatation 13, l'extrémité intérieure de ladite tuyauterie 35 débouchant dans la cloison 9.In accordance with the embodiments shown by way of nonlimiting examples in FIGS. 1, 2 and 8, a heat exchanger 6A, 6D, is mounted in the pipe 19 which connects the lateral opening 17 made in the bottom 5 of the autoclave 1, at pump 8. However, while in the embodiments shown in FIGS. 1 and 2, the heat exchanger 6A is arranged in the pipe 19, outside the autoclave 1, in the embodiment shown in FIG. 8, the heat exchanger 6D is housed in a pipe 35 which connects the pump 8 with the treatment tank 10, and more precisely inside the expansion zone 35 which is inside of the expansion zone 13, the inner end of said piping 35 opening into the partition 9.

Conformément aux modes de réalisation représentés à titre d'exemples non limitatifs aux figures 3 à 5, l'ouverture 17 est directement reliée à la pompe 8 par une canalisation 21 et l'échangeur de chaleur est placé dans un logement prévu dans la zone de dilatation 13, à la partie inférieure de cette dernière, en regard de l'ouverture 17. Selon le mode de réalisation représenté à la figure 3, l'échangeur de chaleur 6B est placé dans un logement 22 non-étanche qui relie la cuve de traitement 10 à la zone de dilatation 13. Dans le mode de réalisation représenté aux figures 4 et 5, l'échangeur de chaleur 6C est placé dans le logement 23 qui est étanche par rapport à la cuve de traitement 10 et la liaison entre cette dernière et la zone de dilatation 13 est assurée par une ouverture 25 pratiquée dans la cloison 9 (cf. figure 4), ou par une tubulure qui peut relier le logement 23 à l'ouverture 25 pratiquée dans la cloison 9 ou par une tubulure 26 (cf. figure 5), qui relie la cuve 10 au logement 23, par l'intermédiaire d'un prolongement 27 de ladite cuve 10 situé entre la paroi 14 de l'autoclave et une paroi 28 qui délimite conjointement avec la cloison 9, le fond 5 et la paroi supérieure du log ornent 23, la zone de dilatation 13.In accordance with the embodiments shown by way of nonlimiting examples in FIGS. 3 to 5, the opening 17 is directly connected to the pump 8 by a pipe 21 and the heat exchanger is placed in a housing provided in the area of expansion 13, at the bottom of the latter, opposite the opening 17. According to the embodiment shown in Figure 3, the heat exchanger 6B is placed in a non-sealed housing 22 which connects the tank treatment 10 at the expansion zone 13. In the embodiment shown in FIGS. 4 and 5, the heat exchanger 6C is placed in the housing 23 which is sealed relative to the treatment tank 10 and the connection between the latter and the expansion zone 13 is provided by an opening 25 made in the partition 9 (cf. FIG. 4), or by a tube which can connect the housing 23 to the opening 25 made in the wall 9 or by a tube 26 ( see Figure 5), which connects the tank 10 to the housing nt 23, by means of an extension 27 of said tank 10 situated between the wall 14 of the autoclave and a wall 28 which delimits jointly with the partition 9, the bottom 5 and the upper wall of the log adorn 23, the dilation zone 13.

La pompe 8 de circulation du bain de traitement est de n'importe quel type approprié et peut être, notamment, soit une pompe centrifuge équipée ou non d'un système de robinet inverseur propre à assurer une circulation réversible, soit une pompe hélicoïdale, assurant la circulation du bain de l'ouverture 17 en direction de la tuyauterie 16 ou dans la direction opposée. Dans le cas de la pompe centrifuge non équipée d'un robinet inverseur, le bain ne peut circuler que dans la direction allant de l'ouverture 17 vers la tuyauterie 16, ce qui convient généralement pour le traitement des fils, tissus ou tricots enroulés en ensouples.The pump 8 for circulating the treatment bath is of any suitable type and can be, in particular, either a centrifugal pump equipped or not with a reversing tap system suitable for ensuring reversible circulation, or a helical pump, ensuring the circulation of the bath of the opening 17 in the direction of the piping 16 or in the opposite direction. In the case of the centrifugal pump not equipped with a reversing valve, the bath can only circulate in the direction from the opening 17 towards the piping 16, which is generally suitable for the treatment of threads, fabrics or knitted fabrics wound in beams.

Le moteur d'entraînement de la pompe 8 peut être un moteur à vitesse variable.The drive motor of the pump 8 can be a variable speed motor.

L'entraînement de la pompe de circulation du bain par un moteur à vitesse variable permet de contrôler et d'ajuster le débit du bain à travers la matière, ainsi que les variations de débit, au démarrage de la pompe par exemple.The drive of the bath circulation pump by a variable speed motor makes it possible to control and adjust the flow of the bath through the material, as well as the variations in flow, when starting the pump for example.

Un socle 20 solidaire de la tuyauterie 16 porte un cône ou analogue (non représenté) de réception des porte-matière 3 dans lesquels le bain peut être réparti en cas de besoin, pour le traitement de bobines par exemple, par l'intermédiaire d'un caisson 30 (cf. figure 6a) muni de perforations 34 pour le retour rapide du bain vers le fond de la cuve 10, en vue de sa reprise par la pompe 8.A base 20 integral with the piping 16 carries a cone or the like (not shown) for receiving the material carriers 3 in which the bath can be distributed if necessary, for the treatment of coils for example, by means of a box 30 (cf. FIG. 6a) provided with perforations 34 for the rapid return of the bath to the bottom of the tank 10, with a view to its recovery by the pump 8.

L'autoclave 1 est mis sous pression statique au moyen d'un gaz comprimé, tel que de l'air comprimé, qui est introduit par les vannes 12 munies chacune d'une purge d'air. L'introduction de gaz comprimé permet d'asservir les hauteurs du niveau de bain dans la zone de dilatation 13 et dans la zone de traitement 10. En effet, si on remplit l'autoclave 1 de gaz comprimé en purgeant du côté de la cuve 10 et en fermant du côté de la cloison 9, le niveau s'établira dans ladite cloison de telle manière qu'il règne une pression de gaz comprimé dans la cloison égale à la différence de niveau entre la cuve 10 et la cloison 9. Pour réduire le volume de bain, c'est-à-dire pour éviter que le niveau de bain monte dans la cloison 9, il est souhaitable, en pareil cas, d'injecter de l'air comprimé dans la cloison pendant le remplissage, afin de stabiliser le niveau à la valeur désirée.The autoclave 1 is put under static pressure by means of a compressed gas, such as compressed air, which is introduced by the valves 12 each provided with an air purge. The introduction of compressed gas makes it possible to control the heights of the bath level in the expansion zone 13 and in the treatment zone 10. In fact, if the autoclave 1 is filled with compressed gas by purging on the side of the tank 10 and by closing on the side of the partition 9, the level will be established in said partition so that there prevails a pressure of compressed gas in the partition equal to the difference in level between the tank 10 and the partition 9. For reduce the bath volume, i.e. to prevent the bath level from rising in the partition 9, it is desirable, in such a case, to inject compressed air into the partition during filling, in order to to stabilize the level at the desired value.

La machine conforme à l'invention peut fonctionner à pleine capacité ou à capacité réduite. Dans ce dernier cas, un dispositif 29 permet de relier les porte-matière 3 de capacité réduite au cône de réception, tout en les plaçant aussi bas que possible dans la cuve 10, ce qui permet d'ajuster le niveau du bain à la partie supérieure des porte-matière sans être obligé de remplir complètement la cuve 10. Il est ainsi possible, dans le cas de production réduite, de réduire le volume de bain et de réduire la consommation d'eau, de produits chimiques de traitement et d'énergie calorifique, en adaptant ces consommations à la réduction de la quantité de matières textiles 4 à traiter présentes dans la cuve 10. Dans ce cas, la dilatation a lieu non seulement dans la zone de dilatation 13, mais également dans la zone 16 de la cuve 10 qui surmonte les porte-matière 3.The machine according to the invention can operate at full capacity or at reduced capacity. In the latter case, a device 29 makes it possible to connect the material carriers 3 of reduced capacity to the reception cone, while placing them as low as possible in the tank 10, which makes it possible to adjust the level of the bath to the part upper of the material holders without having to completely fill the tank 10. It is thus possible, in the case of reduced production, to reduce the volume of bath and to reduce the consumption of water, chemicals of treatment and calorific energy, by adapting these consumptions to the reduction of the quantity of textile materials 4 to process present in the tank 10. In this case, the expansion takes place not only in the expansion area 13, but also in the area 16 of the tank 10 which surmounts the material holders 3.

Dans ce cas, où le volume de bain est réduit pour être adapté à une production réduite, la différence de pression entre la zone de dilatation 13 et la zone de traitement 10, correspond à la différence de niveau de bain entre ces deux zones 13 et 10, à laquelle il y a lieu de rajouter ou de retrancher, selon le sens de circulation du bain de traitement, les pertes de charges à travers le circuit de communication zone de traitement 10 - zone de dilatation 13; il faut alors asservir les pressions entre ces deux zones pour obtenir les niveaux de bain souhaités, en réglant l'introduction de gaz comprimé respective dans ces deux zones, par les vannes 12, comme indiqué plus haut.In this case, where the bath volume is reduced to be adapted to a reduced production, the pressure difference between the expansion zone 13 and the treatment zone 10, corresponds to the difference in bath level between these two zones 13 and 10, to which it is necessary to add or subtract, depending on the direction of circulation of the treatment bath, the pressure drops through the communication circuit treatment zone 10 - expansion zone 13; it is then necessary to control the pressures between these two zones to obtain the desired bath levels, by regulating the introduction of respective compressed gas into these two zones, by the valves 12, as indicated above.

Il est en outre possible de réduire le volume de bain en équipant l'autoclave de corps morts horizontaux 31 qui occupent les zones mortes entre des piles 32 de matières textiles à traiter portées par des porte-matière 3 (figure 6 et 7).It is also possible to reduce the volume of bath by equipping the autoclave with horizontal dead bodies 31 which occupy the dead zones between stacks 32 of textile materials to be treated carried by material carriers 3 (FIGS. 6 and 7).

On obtient, grâce à la combinaison de la cloison 9 et des corps morts 31, une machine de traitement liquide ou gazeux de matières textiles, ou d'autres matières fibreuses ou poreuses, dans laquelle le volume, ou rapport, de bain nécessaire au traitement est considérablement réduit comparativement aux machines connues dans l'Art Antérieur, cette réduction impliquant une économie d'eau et une économie d'énergie qui résultent de la réduction des quantités d'eau nécessaires au traitement, et une productivité améliorée.We obtain, thanks to the combination of the partition 9 and the dead bodies 31, a liquid or gaseous treatment machine for textile materials, or other fibrous or porous materials, in which the volume, or ratio, of bath necessary for the treatment is considerably reduced compared to the machines known in the prior art, this reduction implying a saving of water and an energy saving which result from the reduction of the quantities of water necessary for the treatment, and an improved productivity.

De plus, les rejets polluants (produits chimiques, matières colorantes) sont réduits, par voie de conséquence, représentant une diminution notable de la pollution de l'environnement.In addition, pollutant releases (chemicals, dyestuffs) are reduced, consequently, representing a significant reduction in environmental pollution.

En outre la disposition particulière de la pompe et l'entraînement par moteur à vitesse variable ont pour effet d'optimiser les performances de cette dernière et de réduire la consommation d'énergie pour le fonctionnement de la pompe, compte tenu du circuit du bain de traitement.In addition, the special arrangement of the pump and the variable speed motor drive have the effect of optimizing the performance of the latter and reducing the energy consumption for the operation of the pump, taking into account the circuit of the bath. treatment.

L'expansion interne du bain, en outre, permet d'économiser l'énergie calorifique perdue par le refroidissement dû à l'expansion extérieure.The internal expansion of the bath, moreover, saves the heat energy lost by the cooling due to the external expansion.

Les expérimentations réalisées par la Demanderesse ont montré que la machine conforme à l'invention permet de réaliser des économies d'eau et d'énergie de 20 à 30 % par rapport aux machines visant au même but, les plus performantes connues.The experiments carried out by the Applicant have shown that the machine according to the invention makes it possible to achieve water and energy savings of 20 to 30% compared to the machines aiming at the same goal, the most efficient known.
