Description

The invention relates to dyeing and finishing equipment, and more

especially,

  devices for wet processing of textile materials on reels.

  The invention is intended to be applied in finishing factories of the textile industry; for example, for dyeing cotton yarn in coils. There are wet treatment devices of textile materials in coils comprising a vertical cylindrical tank with a lid, a support in the form of a hollow disk with rods on which are wound coils and, arranged in the lower part of the tank, a means of fixing the support, and a circulating pump communicating with the tank via inlet and outlet pipes. In such devices (see, for example, French Patent Specification No. 2,160,644 BO5C 8/20, 1973, Patent of Invention in Great Britain No. 977671 F26B, 1964, Patent of Invention of States No. 2959048 68-184, 1956, etc.), the tank is completely filled with liquid which circulates at

  through the coils of textile material in two directions: from the center to the periphery and from the periphery to the center (alternatively).

  There is a device (see, the USSR inventor's certificate N 609807 DO6B 3/12, 1976) whose support in the form of a hollow disk has an annular partition which forms two cavities of which one is connected to a supply pipe and the other to an outlet pipe of a circulation pump. With this arrangement, the batch of coils with the textile material which are threaded on the rods of the support is divided into two equal parts and the bath which completely fills the tank circulates alternately through the material coils of these two parts in the direction of the periphery towards the center and from the center towards the periphery with a speed twice as big

  about that in other devices.

  There are Eco-mat and 05 Eco-block type devices of the Thies Company (FRG) (see, Kokora GA, Neimark VA "Trend in the development of periodic action equipment for dyeing fibers and yarns", Moscow, TsNIITELLegpiskhemach, 1976, 7) whose vertical cylindrical tank is not completely filled with the bath: the bath does not

  found only in a lower part of the tank.

  The support in the form of a hollow disc with rods receiving the coils is disposed in the lower part of the tank and is connected to the ame15 tubing born from the circulation pump. During operation, the bath circulates through the textile reels only in one direction: from the center to the periphery. Known devices for the wet processing of coiled textile materials are characterized by relatively high consumption of electrical energy, steam, water and materials.

  the quality of treatment is poor.

  By the known devices for the wet treatment of textile materials in coils, the prior art

  the closest, according to the proposed technical solution, is a device described in British Patent No. 1210197 B05C 11/11, 1970.

  This device comprises a vertical cylindrical tank 30 provided with inn lid, installed in the tank, a support in the form of a hollow disk with rods receiving coils arranged in concentric circles, a means for fixing the support and a connected circulation rod to the tank by means of inlet and outlet tubulins. The support in the form of hollow disk is arranged with the rods receiving the coils.in the upper part of the tank and by its central tube, is connected to the supply pipe to the circulation pump. The vertical cylindrical tank is not completely filled with bath and the

  bath circulates through the coils of texti05 material always in the same direction: from the center to the periphery.

  In this device, all the support rods carrying the coils are disposed in a single cavity which is that of the vertical cylindrical tank, and the bath is simultaneously fed from the hollow disk-shaped support to all the rods carrying the coils. This does not make it possible to use the advantages of low bath ratio treatments (bath / material ratio), when the vertical tank is not completely filled with bath, or those of the treatments of a batch of coils divided in two. with the bath circulating alternately in one then in the other of the two directions of circulation; that is, from the periphery to the center and from the center to the periphery, which affects the quality of the treated textile material, especially in the case of treatment with difficultly leveling dyes, for example

dyes in the tank

  The object of the invention is to create a device for wet treatment of textile materials in coils, the production of which of the tank and the arrangement of the support therein would make it possible to increase the quality of the treatment of the textile material in coils. and make the device more economical. The aim is achieved by the fact that a wet textile spooling device which has a vertical cylindrical tank provided with a lid, installed in the tank, a support in the form of a hollow disk with rods for coils arranged in concentric circles, means for fixing the support in the tank

  and a circulation pump connected to the tank by the in-

  Intermediate intake and outlet pipes, in accordance with the invention, further comprises a cylindrical partition installed in the tank concentrically with respect to its walls, in contact with the support, and separating the tank into two cavities, the tubing d supply of the circulation pump being connected to one of the cavities and the outlet tubing to the other. In order to decrease the circumvention of the textile materials by the bath, at the point of contact of the cylindrical partition with the support,

  it is useful to install an annular seal of an elastic material.

  In order to prevent the formation of the foam 15 and to equalize the bath currents from the circulation pump to the material coils

  textile, it is desirable to mount a perforated partition in the lower part of the tank.

  The treatment of textile materials by a bath in the claimed device improves the quality of the material, the treatment on coils by mass becomes 2 to 3 times more regular the efficiency of the device increases from 1.2 to 1.3 times, the specific consumption of the electrical energy being reduced by 20 to 25%.

  The invention will emerge from the description

  A further example of a concrete example is shown schematically in the accompanying drawings, in which: Figure 1 shows an overall view of a device for wet treatment of textile materials in coils, according to the invention; Figure 2 shows the following section IIII

  of Figure 1, in horizontal plane, according to the invention.

  The device comprises a vertical cylindrical tank 1 (FIG 1) with a lid 2 and,

  1, in a manner concentric with respect to its walls, a cylindrical partition 3. The tank 1 is connected by inlet and outlet pipes 4 and 5, respectively, to a circulating pump 6. An annular seal 7 made of an elastic material ensures contact of the cylindrical partition 3 of the vessel 1 with a support in the form of a hollow disc 8 carrying rods 9 receiving coils 10 of textile material, having a central tube 11 and the fasteners 12. The support 8 is fixed to the cylindrical partition 3 by means of a fixing means consisting of a seal 13 in contact with the disc of the support 8 and fixed to a pin 14 to the 15. In the lower part of the tank 1, between the walls of the cylindrical partition 3, a heat exchanger 16 is installed. In addition to this, the device comprises a valve composed of a valve 17 for admitting the bath in the tank 1 connected to the outlet pipe 5, a valve 18 to evacuate the bath from the tank 1 in the connected evacuation line. 4, valves 19 and 20 for admitting compressed air into the tank 1 connected respectively to the pipes 4 and 5, to a valve 21 intended to create a depression in the tank 1 and connected to the outlet pipe 5 and a valve 22 connected to the heat exchanger 16. In the lower part of the tank 1, between its walls and the walls of the

  cylindrical partition 3, a perforated partition 23 is disposed horizontally.

  The cylindrical partition 3 divides the vessel 1 into two cavities: an interior cavity 24 (Fig. 2)

  and an annular cavity 25 in which coils 10 in concentric circles are arranged.

  The device operates as follows.

  The support 8 (Fig. 1) with the coils 10

  threaded on the rods 9, one half of which is arranged on one side of the annular lining 7 and the second half on the other side, is transported, hooked by the fasteners 12, to the cylindrical vessel. vertical, 05 using an electric hoist. Then, using the central tube 11 and the pin 14, the support 8 is centered, to facilitate the mounting of the support 8 in the tank 1, the central tube 11 is of greater height than the rods 9 and is placed in place by the intermediary of its resilient annular seal 7 on the cylindrical partition 3. Then, with the aid of the seal 13, the flywheel 15 and the pin 14, the support 8 is fixed on the cylindrical partition 3 and the tank 1 is closed with the lid 15 2. Thus, the support in the form of hollow disk 8 is coupled to the inlet pipes 4 and outlet 5 of the circulation pump 6. In this case, half of the coils 10 of textile material is disposed in the interior cavity 24 (Fig. 2) and the other half

  coils 10 are in the annular cavity 25.

  When the device is ready for its implementation, a vacuum is created in the tank 1 (the vacuum pump is not shown in the drawing), for example, by the valve 21 (FIG. in this tank is sent from a bath preparation tank (not shown in the drawing) the treatment bath via the valve 17 and the circulation pump. In this case, it is not the whole tank that is filled with liquid, but only one of its cavities, in this case the inner cavity 24 (Fig. 2) with its hollow disk-shaped support 8 (Fig. 1) and its coils 10 of textile material. The bath is stopped by closing the valve 17 when the bath begins to arrive passing through the bins 10 of textile material in the annular cavity (Fig. 2). By filling the inner cavity 24, the bath passes through the coils 10 of material

  positioned in this cavity 24 (circulation from the periphery to the center), arrives inside the hollow disc forming the support 8 (FIG 1) and then passes through the textile material coils 10 arranged in the annular cavity 25 (Fig. 2) (circulation from the center to the periphery). After reversing the operation of the circulation pump 6 (Fig. 1), the bath is transferred from the inner cavity 24 (Fig. 2) into the annular cavity 25. In this case, the bath passes through the perforated partition 23 (FIG 1), which distributes and equalizes the bath streams arriving from the circulation pump 6 to the textile coils 10 by decreasing the formation of foam and fills the cavity 25 (FIG 2) the capacity of which is equal to that of the cavity 24. Thereafter, the bath passes through the coils 10 of textile material disposed in the cavity 25 circulating from the periphery towards the center, arrives inside the support in the form of a hollow disc 8 (FIG. ) and passes through the coils 10 of textile material disposed in the cavity 24 (Fig.

  2), traveling from the center to the periphery.

  During the operation of the device, the bath located in the lower part of one of the cavities, for example the cavity 24, is maintained, at the time of the connection of the other cavity, in this case, the cavity 25, on the pump 6 (Fig. 1) to a level such that the textile coils 10 in the cavity 24 (Fig. 2) are above the bath level, the bath level in the cavities 24 and 25 30 does not then exceed the level of disposition of the perforated partition 23 (FIG 1) in the vertical cylindrical tank 1. The heating and cooling of the bath are made using the heat exchanger 16

  which is placed in the lower part of the tank 1, 35 in the internal cavity 24 (Fig. 2), and is completely immersed in the bath, contributing to the distribution and equalization of the bath currents arriving in the bath.

  1 - 1 towards the coils 10 of textile material from the circulation pump 6. The steam is sent into the heat exchanger 16 through the valve 22. The bath treatment of the coils 10 can be done, both at 05 depression constant in the device with an overpressure: in the latter case, the device is filled with gas. The introduction of additional chemical agents into the device can be done by

  example, by the same valve 17 through which the treatment bath is introduced into the device.

  After the end of the treatment with the bath, the circulation pump 6 is stopped, the bath is drained through the valve 18 in the discharge line and, through the valves 19 and 20 is alternately sent the compressed air which carries out the spinning of the coils 10 of textile material disposed in the cavities 24 and 25 (Figure 2). The treatment of the material in the device is completed, the lid 2 (FIG 1) of the vertical cylindrical tank 1 is opened, the support 8 is removed, the latter is turned over and, depending on the type of wet treatment performed, either the material is removed from the rods 9, the support 8 with the coils 10 is sent to drying. Thus, the coils 10 of textile material, under the conditions of incomplete filling of the vertical cylindrical vessel 1 with the bath, are treated with this bath which circulates through the material in both directions: from the periphery to the center and from the center to the periphery. Then, since the batch of the material is divided into two equal halves and the bath is alternately pumped through these halves, the rate of circulation of this liquid through the coils 10 of textile material is almost doubled without increasing the flow rate.

of the circulation pump.

  This is achieved by the presence in the wet treatment device of textile materials in coils 10, of the cylindrical partition 3 installed in the vertical cylindrical tank 1 in a concentric manner with respect to the walls of the tank and which SO05 the, being in contact with the medium in the form of a

  hollow disk 8, divides the tank 1 into two cavities: an inner cavity 24 and an annular cavity 25, one of which is connected to the supply pipe 4 and the other to the outlet pipe 5 of the pump. circulation 6.
