Description

The invention relates to a method and an apparatus for treating textile material in a closed treatment container, which contains at least one goods storage for receiving textile goods during at least part of the treatment period. In this case, the textile goods connected at their ends to form an endless strand of goods is circulated by means of a gaseous transport medium which is acted upon by the transport nozzle means onto the product strand on a circulation path which contains the transport nozzle means and the reservoir.

After this so-called aerodynamic system working JET treatment plants, for example. JET or nozzle dyeing machines are in practice in various embodiments in use. They differ from hydraulic JET treatment machines basically in that the transport medium flow acting upon the transport nozzle means is not formed by the treatment liquor but by a gaseous transport means, in particular air and / or steam, inert gas or the like. Accordingly, the ratios in hydraulic JET treatment machines are not readily transferable to JET or jet treatment plants which operate on the aerodynamic principle. Examples of JET treatment machines according to the aerodynamic principle are approximately in the EP 0 133 897 and the DE C2 198 13 593 described, just to name a few. At the time of the DE C2 198 13 593 To be taken treatment device at least two axially juxtaposed goods storage are provided in the lockable treatment container, each of which is intended to accommodate a separate endless strand of goods, associated with the goods storage nozzle transport means in circulation and at the outlet of the nozzle transport means, ie when entering the goods storage is tabulated. The transport nozzles of the parallel juxtaposed goods storage are connected to the pressure side of a common blower, which sucks a vapor / air mixture from the treatment vessel and promotes transport medium in the transport nozzles.

Common to the described in the two publications JET treatment devices that the endless strand of goods led out of the memory to a lying above the treatment tank roller from the treatment tank and from the deflection of the product strand by approximately 180 ° causing roller from a downstream Passing through the transport nozzle, which is also arranged outside the treatment tank and causes the reintroduction of the fabric strand in the treatment tank. The lying outside of the treatment container parts of the circulation path of the endless strand of goods pass through corresponding housing parts, which also surround the guide roller and the transport nozzle and which are placed on the treatment container and connected in a gastight manner with this. This design principle makes it necessary that the gaseous transport medium flow of the transport nozzle (s) leading gas cycle with at least one fan, the distribution lines and leading to the respective transport connection line outside the treatment tank, so that through these parts, the surface of the machine and thus the heat radiation surface is increased. Apart from that, the external gas circulation is associated with flow losses, which are reflected in a correspondingly high electrical energy consumption during operation of the machine.

Due to the loading capacity of the memory and the associated larger memory width is a Einagafelung the emerging from the respective transport nozzle goods strand when entering the memory for a proper flow of goods required. In a lying outside the treatment tank flow circuit of the gaseous transport medium arises for structural reasons, a relatively large distance for the strand of goods, which is perceived as disadvantageous under certain conditions. For example, in the DE C2 198 13 593 a substantially vertically oriented Abtafler is provided, which is connected to a common with the transport nozzle transport nozzle means forming transport path for the goods strand connects and performs a reciprocating pivotal movement.

At one of the DE C2 41 19 152 known apparatus for the wet treatment of textile material, which also operates on the aerodynamic principle, may be arranged side by side in the cylindrical treatment container in the axial direction of the container a plurality of memory, so that a corresponding number of strands of goods can be treated independently. Each memory is associated with a transport nozzle, which is arranged within the treatment container in a horizontal orientation and into which the respective strand of goods on the goods strand outlet side of the memory via a likewise disposed within the treatment container guide roller is introduced, the goods strand by 90 ° from the vertical direction in the diverts the horizontal direction of travel. The transport nozzle is connected via an arranged in the treatment tank line piece with the pressure side of a radial blower, which is inserted projecting through a ceiling opening in the shell of the treatment tank with a vertical orientation of the axis of rotation of Gebläselaufrads in the container interior. The radial fan has a housing connected to the inside of the treatment tank, which is provided with a suction opening, via which air is sucked from the interior of the treatment tank. The fan motor is mounted on the ceiling opening enclosing, connected to the container shell annular flange, wherein the motor shaft is inserted by means of a pressure-tightly enclosing sleeve in the container interior. At the goods strand exit side of the transport nozzle is followed by a crank mechanism in a horizontal plane about a vertical axis pivotable guide tube in the form of a flattened funnel, the protrudes into the channel-like memory on the Warenstrangeinlaufseite and facing a provided with perforations wall surface of the memory. This wall surface is inclined so that the strand of material impinging thereon is deflected downwards into the store, whereby the reciprocating movement of the guide tube displaces the goods strand entering the storage for the purpose of the screening.

The scanning device constituted by the guide tube which carries out a reciprocating pivoting movement results in a more or less abrupt change of direction of the strand of goods during the entry into the reservoir, in cooperation with the baffle wall of the reservoir having perforations. However, such distractions may, depending on the type of goods, cause adverse effects on the surface of the strand of goods. For certain types of goods and a proper Abtafelung the strand of goods is not guaranteed, so that tipping of the teaspooned goods strand formed in the memory goods package in the boarding can not be excluded and can occur when removing the strand of goods from the memory entanglements or other disturbances in the goods flow ,

Based on this prior art, the invention therefore an object of the invention to provide a method and apparatus for treating strand-like textile product of the type mentioned, which ensure a trouble-free flow of goods even with larger storage capacities, at the same time an economical operation of the device with the lowest possible Electricity and heat consumption is possible.

To solve this problem, the inventive method has the features of claim 1, while the inventive device is the subject of claim 6.

In the new process, the textile product is initially connected at its end to an endless strand of goods. The product strand is then given a circulating movement on a circulation path by means of a conveying medium flow which is acted upon by transport nozzle means on the product strand, which circulation path runs completely within the treatment container and contains the transport nozzle means and the reservoir. The emerging from the transport nozzle means strand of goods is moved when entering the store by a reciprocating movement of the transponder nozzle means itself for the purpose of Abtafelung.

The fact that the product strand is not led out on his circulation path to a lying above the treatment tank deflection roller and introduced by a downstream transport nozzle back into the treatment tank, because of the omission of an outer Transportmediumkreislaufs a significant reduction in flow losses and thus a lower electrical energy consumption for operation achieved the blower. On the other hand, the immediate movement of the transport nozzle means even very favorable conditions for a perfect flow of goods even with a wide memory and in particular very stable conditions when Eintafeln the strand of goods in the memory with the result that even with a wide memory, the example. A loading capacity of up to about 275 kg and more, a flawless flow of goods is guaranteed and in particular a tip over the package of goods in the Einagafelung and difficulties in the withdrawal of the strand of goods are avoided from the memory. Also, adverse effects on the surface of the continuous strand of goods, such as may result from abrupt changes in direction associated distractions of the strand of goods excluded, which is essential in the treatment of delicate textiles.

Particularly expedient conditions arise when the transport nozzle means are pivoted in the treatment vessel about a vertical axis. In this case, the goods strand can be moved back and forth in the passage through the goods strand by the transport nozzle means when entering the memory, so that the strand of goods when entering the memory performs a combined movement resulting from the mentioned thrust movement of the transport nozzle means about its vertical pivot axis and a movement of the expiring from the nozzle transport means goods strand in the longitudinal direction of the nozzle transport means and thus in the storage depth. These two components of movement can be combined with one another such that, when entering the store, the product strand carries out a movement parallel to the longitudinal axis of the treatment container over the storage width, with the result that an optimization of the insertion process can be achieved. If necessary, alternatively, both movements can be generated separately from each other in temporal succession

A treatment device for textile goods in the form of at least one continuous strand of goods operating according to the described method has a closable treatment container with at least one in the treatment container arranged goods storage for receiving the strand of goods, at least during a portion of the treatment period, wherein the goods storage is oriented in a preferred embodiment perpendicular to the longitudinal axis of the preferably cylindrical treatment container. The transport means for transporting the goods strand have from the goods strand traversed transport nozzle means with a Warenstrangeinlauf and a Warenstrangauslauf, which can be acted upon by a the material strand an advancing movement in a circumferential direction gaseous transport medium. These transport means are arranged completely within the treatment container. Any housing parts and the like which lie outside the treatment container and are connected to the latter for the transport nozzle means and for the transport medium flow serving to supply them are dispensed with. Also included in the treatment tank are means for exposing a treating agent to the strand of goods and guiding and guiding means for the commodity strand, through which the circulating endless commodity strand is guided on a circulation path containing the transporting nozzle means and the product storage in the treatment tank. The transport nozzle means are movably mounted in the treatment tank. They are associated with adjusting means by which they can achieve a movement of the product strand emerging from its strand outlet when entering the downstream goods storage causing movement.

In a preferred embodiment, the transport nozzle means are pivotably mounted in the treatment container about a vertical axis. They are associated with their own blower, which in the region of the top of the treatment tank on this with a substantially vertical Gebläselaufradachse is attached, which can simultaneously form the pivot axis of the transport nozzle means. The blower expediently has a suction pipe opening into the treatment tank and a pressure pipe which is coaxial therewith and which is connected to the transport nozzle means. The arrangement can be made such that the suction and / or the discharge nozzle with respect to the container is preferably pivotally mounted about the axis of rotation of Gebläselaufrads. This results in a maximum distance between the pivot axis of the transport nozzle means in the areas of their Warenstrangeinlaufs and their over the goods storage infeed Warenstrangauslaufs with the result that required for the laying of the goods strand when Eintafeln in the goods storage swing angle range can be kept relatively small even with wide product storage.

In an advantageous embodiment, the transport nozzle means each have a transport path for the goods strand, which ends in the goods strand outlet and which is movable with the transport nozzle means. The transport path may have a goods outlet outlet exhibiting outlet part, which is mounted in the direction of passage of the goods strand by the transport nozzle means telescopically displaceable on this. The outlet part is coupled with an adjustment device of the adjusting means which gives it a reciprocating movement, so that the goods strand outlet can perform a combined movement resulting from the pivoting movement of the conveying nozzle means about the pivot axis and the telescopic reciprocating movement in the direction of the transport means Thread strand of the outlet part results. The pivoting device and the adjusting device can by a control device be coupled together by the gift device and the adjusting device for generating this combined movement of the goods strand outlet are jointly controlled. Alternatively, they can also be controlled separately from each other in chronological order.

Further advantageous features and modifications of the new method and the new device are the subject of dependent claims.

The figures of the drawing illustrate embodiments of a device according to the invention in the form of a High-temperature piece dyeing machine with a trained as a cylindrical vessel treatment tank 1, which is pressure-tightly sealed at both its end faces by welded dished ends 2. In the treatment container 1, in the exemplary embodiment according to FIGS. 5, 6, six goods stores are provided, which are designated I - VI and of which only one store, for example the store III, is illustrated in the section of the piece dyeing machine illustrated in FIG. Each goods storage I - VI is bounded by two parallel side walls 3 and a bottom wall 4, which is connected to the side walls 3, as can be seen, for example, from Figures 1, 3. The bottom wall 4 is designed as a sliding floor by FTFE rods arranged in parallel or by design with PTFE tiles in a conventional manner, both embodiments, a drainage excess liquor in the designated in Figure 3 5 space below the bottom wall 4 in the treatment vessel. 1 allow. The side walls 3, which are also referred to as goods boundary walls, are each formed on their inside with a PTFE coating or as solid plate parts, such that, as in the case of the bottom wall 4, a friction-reducing arrangement results. An inner cover 6 (FIG. 3) is connected to the side walls 3, so that the goods store has a substantially U-shaped configuration with a fabric strand inlet opening 7 and a fabric strand outlet opening 8. In the illustrated embodiment, the goods storage devices I to VI each have the same axial goods storage width, which may typically be 800 mm and more for a treatment container diameter of approximately 2250 mm.

The side walls 3 of each of the goods storage I - VI are opposite to the indicated at 9 in Figure 2 treatment tank longitudinal axis arranged at right angles, but they can in certain individual cases with the treatment vessel longitudinal axis 9 include equal, deviating from 90 ° angle. One of the dished bottoms 2 has a manhole 10 which is coaxial with the treatment tank longitudinal axis and which is closed in a pressure-tight manner by a removable cover 11.

In each of the goods storage I - VI performs a closed with a removable pressure-tight closure 12 loading and unloading, which is located approximately at the height of the horizontal diameter plane 13 (Figure 3) of the treatment tank 1. On the underside of the treatment container 1, a liquor receptacle 14 is provided, which is connected to the container interior and intended to receive the effluent of the fabric processing agent (liquor) is determined. The content of the liquor receiving container 14 is dimensioned such that the total amount of liquor, less the liquor carried by the textile product, can be absorbed without the goods moving in the respective goods store coming into contact with a liquor level outside the goods.

At a distance above the lying below the plane of the diameter 13 Warenstrangauslauföffnung 8 of the respective goods store leads at each goods storage I - VI welded to the shell of the treatment tank 1 cylindrical pipe socket 15 in the container interior, which is vertically aligned with its axis and in the in FIG 17 designated symmetry center plane of the associated goods memory is located. The pipe socket 15 carries at its end an annular flange 18 on which a blower unit 19 is mounted. The blower unit 19 has an upper housing part 20 with an impeller housing 21 which includes a Radialgebläselaufrad 22 which rotates about a coaxial with the axis of the pipe socket 15 vertical axis of rotation 16 and is coupled with an attached to the upper housing part 20 electric motor 23. The electric motor 23 is a variable-speed three-phase motor for converter operation, which is designed to control the respectively required gas flow rate. Its shaft is sealed by a shaft seal 24 against the housing interior. In the impeller housing 21, a spiral baffle 25 (Figure 4) is arranged that redirects the promoted by the Gebläselaufrad 22 gaseous medium into an axis of rotation 16 coaxial outer flow channel 26 which establishes a pressure-side connection with the impeller housing 21.

In the pipe socket 15 a part of the lower housing part of the blower unit 21 forming, with a small radial distance inserted cylindrical inner shell 27 is rotatably mounted, which is coaxially aligned with the axis of rotation 16. The inner jacket 27 is sealed at the edge against the annular flange 18 by means of a seal, for example, a labyrinth seal or a grooved collar, and radially rotatably supported by a suitable profile 29 on the annular flange 18 and suspended axially. Coaxial with the axis of rotation 16 extends in the inner shell 27 an internal, provided with a suction cone flow channel 30 which leads as a suction channel to the Gebläselaufradeintritt, the Ansaugstutzen forms and opens at its opposite end in the interior of the treatment vessel 1. The inner coaxial flow channel 30 defines with the shell 27 on its outer side a cylindrical continuation 26a of the outer flow channel 26. Thus, in the blower unit 21, two concentric vertical flow channels 26, 26a; 30 formed, wherein serving as a suction channel flow channel 30 widens conically toward the container interior and is closed at 31 below to the outside against the inner shell 27.

The blower unit 19 can be removed from the annular flange 18 as a whole and replaced if necessary by a blower unit of different performance or delivery characteristics. Since the pipe socket 15 and the annular flange 18 designed as welding flange remain the same, in a blower unit replacement, only the fan impeller 22 and the impeller housing 21 need to be stepped in different sizes.

With the rotatably mounted inner shell 27 and fixedly connected to this coaxial flow channel 30, the tubular Warenstrangeinlaufteil 32 is designed as a ring nozzle transport nozzle 33 rotatably connected. The fabric strand inlet part 32, which is designed essentially as a 60 ° pipe bend, is completely lined with PTFE on its inside surface in such a way that this lining can be inserted after the stainless steel production of the blower base part. It has a substantially parallel to the container diameter plane 13 extending limited Warenstrangeinlauföffnung 34 which is arranged at a maximum distance from the container diameter plane 13, so as to ensure a favorable trigger angle of the indicated in Figure 1 at 35 endless strand of goods from the Warenstrangauslauföffnung 8 of the goods storage and to make room for yet to be explained Warenstrangleiteinrichtungen. The Warenstrangeinlaufteil 32 leads to an inlet nozzle part 35 which defines an annular gap 37 with a nozzle member 36, to which a cylindrical nozzle part 38 and a diffuser 39 connect. The annular gap 37 is located in a cylindrical nozzle housing 40, which is welded to the inner jacket 27 and communicates with the pressure medium with the transport medium outer flow channel 26a. The diffuser 39 is followed by a coaxial transport tube 41, which may consist of PTFE and which in turn opens into an outlet bend 42 of larger diameter, which together with the transport tube 41 forms a transport path and can initiate the exiting strand of goods in the storage inlet opening 7. The outlet bend 42 opens, as can be seen from Figure 3, at a small distance above the boundary of the inlet opening 7 to which it is aligned approximately parallel opening side.

In the cylindrical nozzle housing 40 open around its axis distributed injection nozzles 43, which are connected via a flexible PTFE stainless steel fabric hose 44 with a treatment agent supply line 45. The injection nozzles 43 act as atomizing nozzles in the direction of the annular gap 37, so that a uniform action of the treating agent injection stream is achieved on the goods strand 35 passing through the transport nozzle 33.

The arrangement of the atomizing nozzles 43, in one embodiment as flat jet nozzles, is such that the jet direction indicated by arrows in FIG. 3 is almost identical to the gas flow and thus supports their effect. By both media, namely the gas flow and the atomizing in the annular cross-section of the transport nozzle treatment liquor, an optimal treatment liquor distribution is achieved on the continuous strand of goods. In the annular gap 37 downstream cylindrical nozzle member 38 is a mixing zone, in which again a distribution the gas medium in the liquid treatment liquor fluid is achieved. The nozzle part 36 fixedly connected to the cylindrical nozzle part 38 is axially adjustable relative to a closing cover 44 of the nozzle housing 40, so that the annular gap 37 of the nozzle can be adjusted.

Opposite the diffuser 39 adjoining the cylindrical nozzle part 38, the cylindrical transport tube 41 is axially displaceably guided in a slide bearing contained in a support structure 420, so that the transport tube 41 is telescopically displaceable around the path with the downstream inlet tube bend 42 made of PTFE , which is indicated in Figure 3 by the double arrows 46.

At the bottom of the nozzle housing 40, a boom 47 is fixed, which is pivotally connected to a push rod 48, which, as for example. Remove from Figure 2, extends over the axial length of the treatment tank 1 and sealed at 49 performed by a dished bottom 2 is. The push rod 48 is connected to a motor drive indicated at 50, which has, for example, a threaded spindle and together with the push rod 48 forms a pivoting device which can cause pivoting of the transport nozzle 33 and the transport path 41, 42 about the vertical axis of rotation 16 of the blower unit 19. As can be seen, for example, from FIG. 6, in a multi-store embodiment of the piece dyeing machine, the push rod 48 is coupled to the boom arms 47 of all blower units 19, during the actuation of the motor drive 50 of the pivoting device, the transport nozzles 33 and transport sections at all goods stores I-VI are simultaneously pivoted at the same angle about its respective vertical pivot axis 16; they are thus rigid with each other coupled. The size of the designated in Figure 2 at 51 pivot angle between the respective dashed line indicated end positions of the transport nozzle 33 and the transport section 41, 42 depends clearly on the width of the respective goods storage. It is usually on the order of 30 °.

On the transport tube 41, a support bearing 510 is placed immovably, which is longitudinally displaceably guided on a protruding from the boom 47 guide member 52 and to which a rocker arm mechanism 53 engages, which is coupled to a parallel to the longitudinal axis of treatment 9 extending bearing shaft 54, on both Side of the treatment tank 1 is coupled via a lever gear 55 with a motor drive 56, which forms an adjusting device for the transport path together with the shaft 54 and the rocker mechanism 53. Upon actuation of the adjusting device, the outlet sheet 42 and the transport tube 41 is given an adjusting movement in the direction of the transport nozzle 33 passing through the product strand whose size, as already mentioned, is indicated by the double arrows 46.

The two adjusting motor drives 56 and the pivot motor drive 50, which are sealed at 57 by the dished ends 2, are controlled by a common control device 58, which is indicated schematically in FIG. As can be seen from this figure, the two motor drives 50, 56 are controlled so that the outlet sheet 42 moves during the pivoting between the end positions shown in dashed lines in Figure 2 along with the center of his leading into the goods storage inlet opening 7 Strangauslaufsöffnung 58 along a straight line 59 that are parallel is aligned with the treatment vessel longitudinal axis 9 and extends across the respective goods storage. The outlet bend 42 thus carries out two movements, on the one hand a pivoting movement about the rotation axis 16 and on the other a transverse movement in the direction of passage of the goods strand through the transport nozzle 33, ie substantially transversely to the treatment vessel longitudinal axis 9. These two movements can overlap one another, such as already mentioned, to be executed simultaneously. They can be controlled by the control device 58 but also take place in succession. Incidentally, the two motor drives 50, 56, of which the motor drive 50 determines the indicated by the angle 51 pivoting range of the fan base with the transport nozzle 33 and the outlet sheet 42 and the motor drives 56 cause the longitudinal movement of the outlet sheet 42 relative to the transport nozzle 33, also be controlled with different cycle times, so that can be set according to the program in this way, the movement in the Eintafelung, depending on the particular textile material to be treated.

At the same time the Abtafelung can be adapted to different memory widths without this constructive details of the fan base or the transport nozzle, etc., would have to be changed. In practice, storage widths for a loading of about 275 kg and more are possible, the restriction is given up only by the diameter of the treatment tank 1, which must not exceed about 2250 mm in consideration of the requirements of container shipping.

Below the goods inlet part 32 of the transport nozzle 33 is in the treatment tank 1 one to a horizontal Axis rotatably mounted guide roller 60 is arranged, which can extend throughout the goods storage I - VI in the treatment container 1 in the illustrated in Figures 5, 6 illustrated Mehrspeicher piece dyeing machine across all goods storage. Alternatively, and depending on the design but can each be provided for each goods storage I - VI or for a group of goods stores each a separate guide roller 60. This is illustrated in Figures 7 to 9, of which Figures 7 to 8 show the arrangement of a guide roller 60 per goods storage, while Figure 9 shows an embodiment similar to Figures 5, 6, in which two guide rollers 60 are provided which are coaxial with each other each extend over three goods storage. The deflecting roller 60 is mounted on both sides free-running in bearings 61, wherein, as can be seen in particular from Figure 7, the exposed shaft end 62 is arranged in a rectangular profile 63 such that it is shielded from the interior of the treatment container 1. On the shaft end 62, a toothed belt pulley 64 is placed, which is positively coupled at Warenstrangstop via a coupling grid device with the shaft end 62. The toothed belt pulley 64 is coupled to a geared motor 67 via a toothed belt 65 running in the rectangular profile 63 and a second toothed belt pulley 66. Due to the fact that the toothed belt 65 is separated from the interior of the treatment vessel, it is not exposed to any inadmissible temperature stress during operation at goods stop. The second toothed belt pulley 66 with its bearing lies in the region of the outer contour of the treatment container 1. The adjustment of the toothed belt can, for example, be done by a rocker, which is connected to the console of the geared motor 67.

Alternatively to this arrangement, instead of the freewheeling mounted deflection roller 60 and a driven steering roll 60 are used, as shown in Figure 9 is illustrated. Because of the length of the treatment container, for example. With six goods stores, each with 275 kg load, the guide roller 60 is divided in the middle, wherein centrally in the treatment container 1 arranged rectangular bearing bar 68 for receiving the shaft seal and the ball bearing 61 is provided. The two Teilumlenkwalzen 60 are each driven by a geared motor 69, the shaft is performed at 70 sealed by the respective dished bottom 2.

As can be seen from Figure 1, the position of the strand inlet opening 34 and the Warenstrangeinlaufteils 32 to the transport nozzle 33 and the axial position of the guide roller 60 are designed such that the transverse withdrawal angle of the fabric strand 35 does not exceed a permissible level when running up the goods strand from the goods store out , so that, for example, in a knitted fabric mesh shifts do not occur. The strand of goods is deflected by the guide roller 60 in the illustrated embodiment by an angle of more than 90 °, such that on the one hand substantially parallel to the adjoining the inlet opening 34 inner wall of the fabric strand inlet part 32 enters this and on the other hand at a favorable angle is raised by almost 90 ° with the opening boundary 8 out of the memory. The deflection roller 60 is driven in the freewheeling embodiment by friction of the overlying strand of goods 35. The deflecting roller 60 can also be assigned to the incoming goods strand 35 laterally conductive baffles 600, as shown in FIG.

Regardless of the design and the drive of the guide roller 60 is a guide roller 71 (Figures 1, 3) rotatably mounted above the guide roller 60 in the treatment container 1, which sits on a rocker 72, which can be pivoted by a pneumatic actuating cylinder 73 about a pivot point 74 to the guide roller 60 back. By this dashed lines in Figure 3 indicated pivoting of the guide roller 71, a larger wrap angle of the guide roller 60 is achieved for the fabric strand 35, which is also associated with a separation of the surface of the product strand adherent treatment liquor, which is collected by a baffle 76 and a transverse Gutter 76 a and arranged on the left and right of the goods storage boundary walls 3 grooves 76 b is discharged without coming back to the fabric strand 35 into contact. Toward the treatment container interior, the deflecting roller 60 and the guide roller 71 are shielded by a separating plate 76, which is effective for discharging sprayed treatment liquor when the guide roller 71 is pivoted downwards. With the separating plate 76 acts on the Warenstrangeinlaufteil 32 arranged cover plate 77 cooperates, which provides for a separation of the suction of the fan unit 19 of the deflection roller 60 and the guide roller 71 surrounding space, which is shielded inter alia by the partition plate 76 to the container interior.

The amount of gas drawn by the fan unit 19 from the interior of the treatment tank 1, which acts as the transport medium flow through the nozzle housing 40 to the transport nozzle 33, is sucked through the conical flow channel 30 in the fan base to the impeller inlet. Depending on the nature of the textile material to be treated, any fiber fly that may occur, which can lead to the corresponding precipitation of fibers, must be avoided the outlet opening 8 of the goods storage, in each case over the width of the goods storage continuously, a filter surface interposed, which is formed by a rectangular, flat filter element 78. The filter element 78 is arranged vertically and slidably mounted in an upper and lower guide profile 79 and 80 in the container longitudinal direction. At the upper guide profile 79, a cover plate 81 connects to the inside of the container shell, which extends approximately to a central axis line of the cylindrical pipe socket 15.

Due to the displaceability of the filter element 78, an easy accessibility to the filter surfaces is possible even with an arrangement of a plurality of goods storage in the treatment container 1, wherein the filter elements 78, which are flexible, after opening of the manhole closure 11 through the manhole 10 are removable.

As can be seen from Figures 1, 3, the Transpörtdüse 33 is disposed in the upper part of the treatment vessel 1 and formed such that it is as close as possible to the inner contour of the shell of the treatment tank. The transport nozzle 33 is oriented in the illustrated embodiment with horizontal alignment of its longitudinal axis and the transport tube 41. In this arrangement, a very favorable movement of the strand of goods 35 results in the Einagafelung in the goods store. However, embodiments are also conceivable in which the transport nozzle 33 and the transport tube 41 have a slight inclination relative to the treatment vessel diameter plane 13. For example, the axis of the transport nozzle 33 with the diameter plane 13 include an angle of 10 to 30 °.

The Warenstrangeinlauf in the transport nozzle 33 is in the illustrated embodiment, as already mentioned, at an angle of 30 ° to the goods container symmetry plane. It is separated from the conical intake flow channel 30 by the plates 76, 77, which act as air baffles, so that a defined space is formed between the filter surface of the filter element 78 and the conical intake flow channel 30.

The blower base receiving, cylindrical pipe socket 15 is arranged laterally adjacent to the vertical longitudinal center plane of the treatment tank 1, so that its upper limit in the areas of the annular flange 18, the height dimensions of the treatment tank 1 is not significantly increased. This ensures that, with the blower unit 19 removed, the treatment container 1 is suitable for container shipping without additional conversions, etc., having to be made. The treatment tank 1 is smooth-walled on the outside, so that it can be surrounded without further, if necessary, with a heat insulating layer, which leads to a further energy saving.

The elements of the high-temperature piece dyeing machine selected here as an exemplary embodiment lying outside of the treatment tank 1 are indicated in FIG. They consist essentially of a treatment liquor cycle 82, which includes a liquor circulation pump 83 and a heat exchanger 84 and from the liquor receptacle 14 leads to the treatment agent supply line 45 from which the transport nozzles 33 of the individual goods storage I - VI are supplied with treatment agent. The treatment agent circuit 82 also includes a shut-off valve 85 and a liquor drain valve 86. To him are a secondary tank 87 for the total amount of liquor, rinse water and the like and a batch tailing tank 88 connected to a metering pump 89. A bypass line 90, not shown, and valves and fittings, allows a treatment liquor circulation separate from the treatment tank 1, as required for certain treatment steps. Finally, at 91, the treatment tank 1 can be vented or charged with steam, etc.

Finally, it should be mentioned that in certain applications, the transport nozzle 33 could not be mounted in the treatment container 1 about the axis 16, but about another axis pivotable or even displaceable or otherwise movable.
