Description

SPECIFICATION Apparatus for wet treatment of textile material in packages The invention relates to dying-finishing equipment and, more particularly, to apparatus for wet treatment of textile materials in packages.

The invention is intended for use at finishing factories in the textile industry, e.g., for dyeing cotton yarn in bobbins.

Known in the art are apparatus for wet treatment of textile materials in packages, comprising a vertical cylindrical chamber with a cover, a hollow disc carrier with rods for packages which is arranged in the lower portion of the chamber, means for securing the carrier and a circulating pump communicating with the chamber by means of inlet and outlet branches. In. such apparatus (cf. e.g.,. French Patent No. 2160644, B 05 C 8/20, 1973), English Patent No. 977671, F 26 B, 1964, U.S. Patent No. 2959048, 68-184, 1956 et al) the chamber is completely filled with the liquid which circulates through textile packages in two directions: from the centre towards the periphery and from the periphery towards the centre, alternatively.

Known in the art is an apparatus (cf.

U.S.S.R. Inventor's Certificate No. 609807, D06 83/12, 1976) whose hollow disc carrier accommodates an annular partition forming two reservoirs, one of which communicates with the inlet and the other-with the outlet branches of the circulating pump. Thanks to this factor a batch of textile material packages fit on the carrier rods turns out to be divided into two equal portions, and the liquid which the vertical cylindrical chamber is fully filled with consecutively circulates through the packages of these parts of the material from the periphery towards the centre and from the centre towards the periphery alternately with a speed roughly twice as great as usual.

Known in the art are apparatus of the ECO MAT and ECO-BLOC types manufactured by the West German THIES company (cf. G.A.

Kokora, V.A. Neymark. "Trends of Development of Periodic Action Equipment for Dyeing Fibre and Yarn", Moscow, TSNIITELlegpishchemash, 1976, p. 7), whose vertical cylindrical chamber is filled with liquid not in full: it only the lower portion of the chamber that is filled with liquid. A hollow disc carrier with rods for packages is arranged in the lower portion of the chamber and is connected to the inlet branch of the circulating pump. In the working condition the liquid circulates through the packages of textile material invariably in one and the same direction, namely, from the centre towards the periphery.

The prior art apparatus for wet treatment of textile material in packages feature comparatively high consumption of electricity, steam, water and various chemicals, as well as a low quality of the material treatment.

Among the prior art apparatus for wet treatment of textile materials in packages the closest to the claimed one is the apparatus disclosed in English Patent No. 1210197, B05C 11/11, 1970. This apparatus has a vertical cylindrical chamber with a cover, a hollow disc carrier with rods for packages arranged in concentric circles, means for securing the carrier and a circulating pump which communicates with the chamber by way of inlet and outlet branches. The hollow disc carrier with the rods for packages is arranged in the upper portion of the chamber and by means of its central pipe is connected to the inlet branch of the circulating pump. The vertical cylindrical chamber is not fully filled with the liquid and the latter constantly circulates via the packages of textile material in one and the same direction: from the centre towards the periphery.

In this apparatus all the rods of the carrier with the packages of textile material are arranged in one reservoir, namely, the vertical cylindrical chamber, and the liquid is simultaneously fed from the hollow disc carrier to all the rods with packages. This does not permit using the advantages of treatment at short liquor ratio, whereby the vertical cylindrical chamber is filled with liquid not in full as well as the treatment when a batch of material is divided into two parts and the liquid concentrically circulates therethrough in two directions, namely, from the periphery towards the centre and from the centre towards the periphery, alternately, which impairs the quality of treated textile material, especially when the material is treated with hard-to-even dyes, e.g., vat ones.

It is an object of the invention to improve the quality of wet treatment of textile material in packages and update economical operation of the apparatus.

The object of the invention is accomplished by the use of an apparatus for wet treatment of textile material in packages, comprising a vertical cylindrical chamber with a cover, a hollow disc carrier mounted in the chamber and provided with rods for packages arranged thereupon in concentric circles, means for securing the carrier in the chamber, a circulating pump communicating with the chamber by way of an inlet and outlet branches, and according to the invention, said apparatus is provided with a cylindrical partition mounted in the chamber concentrically relative to its walls and contacting with the carrier and dividing the chamber into two reservoirs, the inlet branch of the circulating pump communicating with one reservoir and the outlet one-with the other reservoir.

To decrease the leakage of liquid past the textile material packages, it is expedient that an annular gasket from an elastic material be arranged in the place where the cylindrical par tition makes contact with the carrier.

To prevent foaming and to level off the flows of liquid coming from the circulating pump to the packages of textile material, it is advisable that a perforated partition be installed in the lower portion of the chamber.

Wet treatment of textile material in packages with the use of the herein-disclosed apparatus improves the quality of material, the uniformity of treatment as regards the mass of packages grows 2 to 3-fold, the apparatus capacity is increased by 20 to 30 percent and the specific consumption of electricity is reduced by 20 to 25 percent.

The herein-disclosed invention will be more apparent upon considering the following detailed description of an exemplary embodiment thereof, with references to the accompanying drawings in which: Figure 1 is the general view of the hereindisclosed apparatus for wet treatment of textile material in packages, according to the invention; Figure 2 is a sectional view taken a long ll-ll of Fig. 1, in the horizontal plane, according to the invention.

The apparatus comprises a vertical cylindrical chamber 1 (Fig. 1) with a cover 2 and a cylindrical partition 3 arranged in the chamber 1 concentrically relative to its walls. A circulating pump 6 is connected to the chamber 1 by way of inlet and outlet branches 4 and 5, respectively. Arranged in the chamber 1 is a hollow disc carrier 8 with rods 9 to accommodate packages 10 with textile material, with a central pipe 11 and clamps 12. Said carrier 8 contacts via an annular gasket 7 from an elastic material with the cylindrical partition 3.

The carrier 8 is secured on the cylindrical partition 3 with the aid of a fastener incorporating a seal 13 contacting with the disc of the carrier 8 and secured on a pin 14 by means of a flywheel 15. Mounted in the lower part of the chamber 1 between the walls of the cylindrical partition 3 is a heat exchanger 16.

Besides, the apparatus contains valves comprising a valve 17 for feeding the liquid to the chamber 1 which is connected to the outlet branch 5, a valve 18 for draining the liquid from the chamber 1 to the drain line which is connected to the inlet branch 4, valves 1 9 and 20 for supplying compressed air to the chamber 1 which are connected to the branches 4 and 5, respectively, a valve 2 1 for evacuating the chamber 1 which is connected to the heat exchanger 16. A horizontal perforated partition 23 is mounted in the lower part of the chamber 1 between its walls and the walls of the cylindrical partition 3.

The cylindrical partition 3 divides the chamber 1 into two reservoirs: internal 24 (Fig. 2) and annular 25, in which the packages 10 are arranged in concentric circles.

The apparatus operates as follows. The carrier 8 (Fig. 1) with packages 10 fit on rods 9 of which one half is disposed to one side of the annular gasket 7, and the other half-to the other side therefrom, is transferred with the use of clamps 12 by means of, e.g., a telpher, to the vertical cylindrical chamber 1.

Thereupon, the carrier 8 is centered with the aid of the central pipe 11 and the pin 14, in so doing, for conveniency of mounting the carrier 8 in the chamber 1 the central pipe 11 is made taller than the rod 9, and by its annular elastic gasket 7 is installed on the cylindrical partition 3. Thereafter, the carrier 8 is secured on the cylindrical partition 3 with the aid of the seal 13, the flywheel 15 and pin 14 and the chamber 1 is closed with the cover 2.

Thus, the hollow disc carrier 8 turns out to be connected to the inlet and outlet branches 4 and 5 of the circulating pump 6. Besides, half of the packages 10 of textile material turns out to be accommodated in the internal reservoir 24 (Fig. 2) and the other half of the packages 10-in the annular reservoir 25. As soon as the apparatus is ready for operation, the chamber 1 is evacuated (the vacuum pump is not shown in the Figure), e.g., via the valve 21, and then the working fluid is fed from a preparation tank (not shown in the Figure) via the valve 17 to said chamber with the aid of the circulating pump 6. It is not the whole chamber that is filled with the liquid but only one of its reservoirs, namely, the internal reservoir 24 (Fig. 2) having the disc carrier 8 (Fig. 1) and packages 10 of textile material.

The filling is terminated, the valve 17 is closed when the liquid starts to enter via the packages 10 of textile material into the annular reservoir 25 (Fig. 2). As the liquid fills the internal reservoir 24, it passes along the packages 10 of textile material which are arranged in this reservoir 24 (circulation is from the periphery towards the centre, enters the hollow disc carrier 8 (Fig. 1) and further flows only along the packages of textile material which are arranged in the annular reservoir 25 (Fig. 2) (circulating is from the centre towards the periphery). As the circulating pump 6 is changed over (Fig. 1), the liquid is pumped over from the internal reservoir 24 (Fig. 2) into the annular reservoir 25. The liquid passes through the perforated partition 23 (Fig. 1) which distributes and levels off the flows of liquid coming from the circulating pump 6 to the packages 10 of textile material, diminishing foaming, fills the reservoir 25 (Fig.

2) equalling in volume to the reservoir 24.

Thereafter, the liquid flows along the packages 10 of textile material which are arranged in the reservoir 25, circulating from the periphery towards the centre, enters the hollow disc carrier 8 (Fig. 1) and passes along the packages 10 of textile material which are arranged in the reservoir 24 (Fig. 2) circulating from the centre towards the periphery. During the operation of the apparatus the liquid being in the lower part of, say, reservoir 24, as the other reservoir, for instance, 25 is connected to the pump 6 (Fig. 1), is maintained at such a level that the packages 10 of textile material being in the reservoir 24 (Fig. 2) turns out to be above the level of the liquid, and the level of the liquid in the reservoirs 24 and 25 does not exceed that of the arrangement of the perforated partition 23 in the vertical cylindrical chamber 1 (Fig. 1).The liquid is heated and cooled by means of the heat exchanger 16 mounted in the lower portion of the chamber 1-in the internal reservoir 24 (Fig. 2) and fully immersed into the liquid, thus facilitating the distribution and levelling off of the flows of liquid coming to the packages 10 of textile material from the circulating pump 6. Steam is fed via the valve 22 to the heat exchanger 16. Wet treatment of the packages 10 can be effected both under a permanent vacuum in the apparatus and under gauge pressure therein, in this case the apparatus is filled with gas. Chemical additives can be introduced in the apparatus, e.g., via the same valve 17, through which the working fluid is supplied to the apparatus.

Upon completion of the wet treatment, the circulating pump 6 is disconnected, the liquid is drained through the valve 18 into the drain line, and compressed air is alternately fed to the apparatus via the valves 19 and 20. This air helps press out the packages 10 arranged in the reservoirs 24 and 25 (Fig. 2). At this point the treatment of material in the apparatus is completed, the cover 2 (Fig. 1) of the vertical cylindrical chamber 1 is opened, the carrier 8 is removed therefrom, said carrier is turned over, and depending on the type of wet treatment carried out, the material is either removed from the rods 9, or the carrier 8 with the packages 10 are directed for drying.

Thus, in case the vertical cylindrical chamber 1 is not fully filled with liquid, the treatment of packages 10 of textile material involves the circulation of the liquid in two directions: from the periphery towards the centre and from the centre towards the periphery. Besides, owing to the division of a batch of material into two equal portions and consecutive injection of the liquid therethrough, the speed of liquid circulation through the packages 10 of textile material is almost doubled without increasing the circulating pump capacity.

All this is achieved due to the availability of the cylindrical partition 3 in the apparatus for wet treatment of textile material in packages 10. This partition is arranged in the vertical cylindrical chamber 1 concentrically relative to its walls, and when making contact with the hollow disc carrier 8, it divides the chamber 1 into two reservoirs: internal 24 and annular 25, one of which being connected to the inlet branch 4 and the other-to the outlet branch 5 of the circulating pump 6.
