F: Fabric

This design is directed to the improvement of a porous cylindrical beam device that dyes or processes fabrics in the form of elongated materials such as fabrics, tapes, and yarns.

Many attempts have been made to provide a means for uniformly dispensing treatment liquid through the fabric layers in both the axial and radial directions of the winding fabric. One such attempt is disclosed in Japanese Patent Publication No. 58-5301, in which the horizontally mounted beam apparatus is provided with distribution ports at the upper front and lower center of the partially doubled processing vessel in which the beam is received. These ports are connected to all pipes, heat exchangers and pumps installed outside the unit. The drawback of such a conventional device is that the device as a whole is bulky, expensive, complicated and requires tedious maintenance.

In view of the above drawbacks of the prior art device, the present invention seeks to provide an improved beam treatment apparatus that is relatively compact, simple in structure and capable of effectively and uniformly treating textile materials.

These and other objects and features of this invention will become apparent upon reading the following detailed description with reference to the accompanying drawings, which show, by way of example, preferred embodiments, but this invention is not limited thereto.

According to this invention there is provided a pore beam apparatus for dyeing or processing textile materials, which is a horizontally mounted cylindrical processing vessel having a dish-shaped end cover at one end and a rear end wall at the opposite end. The vessel having a pair of radially opposite peripheral grooves of the beam, wherein the pair of beams are formed of a material winding zone in which a fabric is wound around the annular rims, the annular rims extending outwardly at both ends; A vertically arranged diaphragm is formed in the disc member and the peripheral recesses, respectively, to form a heat exchange chamber together with a rear end wall of the disc which separates the heat exchange chamber from the process chamber extending over most of the beam length. It extends horizontally between the ends and forms the upper and lower flow control zones together with the inner wall of the vessel. A pair of perforated flow control plates comprising: a circulating pump that is separated from the outer surface of the non-clinical fabric and a recirculation pump for supplying treatment liquid through a supply tube extending horizontally into the interior of the beam and in communication with the interior of the vessel. It consists of a pressure storage tank which is supported in place above the regulating zone.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 shows a beam dyeing or processing apparatus 10 for dyeing or processing a woven or knitted fabric F in the form of an elongated material such as cloth, tape, thread or the like. The device 10 is a horizontally mounted cylindrical processing vessel 11 which is circular in cross section and provided with an outward dish-shaped end cover 12 at the front end and a dish-shaped end wall 13 similar to the rear end (opposite end). )

In the vessel 11 a hollow cylindrical beam 14 is mounted concentrically, on either end of which there is a pair of outwardly extending annular support rims 15, 16, between which the fabric F is located. A winding material zone is formed on this beam body.

Several holes 17 are formed in the periphery of the beam 14 and are uniformly distributed around the beam so that the treatment fluid or salt solution pumped into the beam exits through the holes 17 and is wound around the beam. Wet (F). A vertically extending annular support flange 18 for supporting the feed tube 19 lies adjacent the rear end of the beam 14, which feed tube is connected to the recirculation pump 20 at the recirculation pump 20 via a flange 18. It extends horizontally inside.

The support flange 18 also serves to receive and fit snugly the inwardly annular rear end wall 14a of the beam 14.

The vessel 14 may be opened by a frame (not shown) or a suspension device (not shown) until the rear end wall 14a of the beam 14 is hermetically engaged with the horizontal extension 18a of the flange 18. 11) can be inserted into. In this position, the sealing disc 21 is in sealing engagement with the inwardly annular shear end wall 14b of 14, which is adapted to manipulate the mounting and detachment of the beam 14 via the dish-shaped end cover 12. Is connected to the handle 22.

The end cover 12 is clamped in place with respect to the processing container 11 when its outer periphery is hermetically received by the clamping member 23.

3 shows a disk member 24 having a vertically arranged flow control diaphragm, which has a pair of peripheral recesses 24a and 24b placed in diametrically opposed positions and the diameter of the cylindrical beam 14. There is a slightly smaller diameter concentric annular flange 24c. The diaphragm disc member 24 fits into a disciple with the flange member 24c of the disc member sealed to the support flange 18, and the heat exchange chamber 25 together with the plate-shaped rear end wall 13 of the container 11. The heat exchange chamber is distinguished from the processing chamber 26 extending over most of the beam length.

As shown in Figs. 1 and 2, these two chambers are circulated with each other through an annular passage for the treatment liquid formed between the inner wall of the container 11 and the periphery of the disc member 24.

The hole flow control plate 27 is in the form of a trough adapted to fit into the recesses 24a and 24b of the disc member 24 and extends horizontally between the disc member 24 and the inlet end of the container 11. . As can be seen in FIG. 4, the flow control plate 27 has a base portion 27a and upwardly facing edge portions 27b and 27c and a closed end portion 274, with the edge portions at one end. It is connected to each other by the end part 27d, and the opposing end part 27e is blown so that it may flow between the process chamber 26 and the heat exchange chamber 25. As shown in FIG. The closed end portion 27d of the throttle 27 is welded or attached to the inner wall of the container 11 adjacent to the clamping member 23 of the container 11 front end. On the other hand, as shown in FIG. 1, the popped end portion 27e is placed on the disc member 24 with a partition disposed adjacent to the rear end of the container 11. In the illustrated embodiment, one of these two throttle plates 27 forms the first upper flow control zone 28 with the inner wall of the vessel 11, and the other defines the third lower flow control zone 29. Form.

As can be seen in Figure 2, these two control zones are arranged facing each other in diameter. Each throttle 27 extends away from the fabric F wound on the beam 14.

The pressure storage tank 30 is supported outwards on the treatment vessel 11 above the upper control section 28 by conduits 31, 32, through which the tank 30 is connected to the vessel 11. In circulation with the inside.

The pump 20 is a recirculation pump which can connect the flow direction of a process liquid, The preferable example is disclosed in Japanese Unexamined-Japanese-Patent No. 47-17106.

The heat exchange pipe unit 34 is arranged in the heat exchange chamber 25 and connected to the steam inlet valve 35, the steam trap 36, the coolant inlet valve 37 and the coolant outlet valve 38. The treatment liquid discharge valve 39 is connected to the lower control section 29 of the container 11, and the treatment liquid supply valve 40 is connected to the supply pipe 19 adjacent to the pump 20. The pump 20 is driven by a movable porter 41.

Once the fabric (14) wound beam (14) has been mounted in place within the container (11), the dyeing or treatment liquid is introduced through the supply valve (40) and supplied (19) and its end through baffles (42). It is pumped to pass the inside of the beam 14 in the direction of the arrow through, and steam of a predetermined temperature is supplied to the heat exchange pipe unit 34 while the treatment liquid is continuously supplied to the tank 30 until it reaches a predetermined level. The treatment liquid is forced out through the holes 17 of the beam 14 and into the fabric (F) layers, with a main suction stream at each of the upper and lower flow control zones 28, 29 of the treatment chamber 26. And a negative suction stream elsewhere in the treatment chamber 26. The main suction stream goes into the heat exchange chamber 25 through the expanded flow doors 43 and 44 and the side suction stream goes into the heat exchange chamber 25 through the reduced circumferential flow door 45. Thus, the main and secondary suction streams of the treatment liquid are permeated into the heat exchange chamber 25 and returned to the recycle pump 20 for recycling to the beam 14. The main suction stream of treatment liquor is directed towards the inlet of each control zone 28, 29 to draw a nearly horizontal path, and its velocity gradually increases toward the expanded flow 43, 44. Advantageously, turbulent flow of the treatment liquid can be resolved because the throttle 27 is away from the fabric F outer surface on the beam 14, otherwise the turbulent flow of the treatment liquid near the support rim 16 on the suction side is eliminated. This occurs, so that unnecessary dye spots occur at the finishing stage of the fabric F or the dyeing state is not constant.

Also advantageously, because the upper regulating zone 28 communicates with the tank 30 via conduits 31 and 32, which in turn communicate with the heat exchange chamber 25 via the conduit 33. No bubbles may be generated in the tank 30 due to suction being incorporated into a portion of the treatment liquid stream exiting through the fabric F.

More advantageously, the uniformity in the final processing stage of the fabric, in particular in the final processing stage of the fabric, can be achieved by gradually increasing the volume of pores per unit area of the pore throttling plate 27 towards the blocked end portion 27. It can be improved.

If necessary, as in the treatment of the fabric F with increased layer thickness, the recirculation pump 20 is dynamic to change the flow direction of the treatment liquid such that the treatment liquid is drawn into the beam 14 by way of the fabric F. It can be done.

Experiments have shown that, for example, the flow rate of the treatment liquid is 50-60% in the upper control section 28, 30-50% in the lower control section 29, 10-15% in the reduced circumferential flow door 45, A successful treatment can be achieved by design consideration that is about one fifth of the flow between the heat exchange chamber 25 and the tank 30.
