Description

[Detailed description of the invention] Long objects such as textiles, tapes, and continuous chains for slide fasteners are wound in multiple layers on a porous hollow winding shaft to form a cylindrical object, and the dye liquid is passed through the layers of the object to be processed. A high-temperature, high-pressure beam liquid processing machine that processes bleaching liquid and other improved processing liquids by circulating them under pressure; A high-temperature, high-pressure beam liquid processing machine in which the partitioning member and the porous hollow winding shaft are rotated relative to each other is already known.

In this known beam liquid processing machine, the liquid supply pipe and the liquid drainage pipe connected to the pressurized liquid supply chamber and the suction liquid chamber, respectively, are provided at one end of the processing tank, and are connected to the processing liquid circulation system. The other end of the processing tank is provided with an opening/closing lid for entering and exiting the beam to be processed.

Therefore, the processing liquid flowing through the layer of the object to be treated wound on the porous hollow winding shaft is forced to flow from the inside to the outside of the winding layer under pressure against the high pressure on the outside. Although there is little salt flowing in the liquid in the axial direction, the suction flow from the outside to the inside of the winding layer is caused by the high pressure on the outside and the reduced internal suction pressure, and the large pressure difference between the inside and outside connects the drain pipe of the suction and drainage chamber in the direction of the winding axis. There is a tendency for the amount of liquid to flow to be larger on the opposite side.
The degree of processing of the processed material wrapped around both ends of the winding shaft is different.
There were defects resulting in processing spots.

The present invention eliminates the above-mentioned deficiencies.

That is, in the conventional high-temperature, high-pressure beam liquid processing machine, a liquid drain pipe connected to the suction liquid chamber formed inside the porous hollow winding shaft is provided at one end of the conventional processing tank together with a liquid sending pipe, and the tank It is also provided on the inner surface of the tank lid on the other end side to drain the liquid to both sides of the suction and drainage chamber, thereby controlling the amount of processing liquid sucked and distributed within the wound layer extending in the axial direction of the porous hollow shaft. This is done to prevent the occurrence of processing spots by averaging.

The embodiments shown in the drawings will be explained below.

In the drawing, a processing liquid pressure pipe 3 is provided protruding from one end of the processing tank main body 2, and a processing liquid F is placed inside a pressure-resistant processing tank 1, which is provided with a tank lid 5 that can be opened and closed by a hinge 4 at the other end.

It is slidably supported on the outer periphery of flanges 9 and 10 provided on both sides.

A partitioning member 11.12 is provided on the outer surface of the liquid feeding tube 8 and protrudes in the diametrical direction along the axial direction of the liquid feeding tube 8, the tip of which slides into contact with the inner surface of the porous hollow wound shaft 6. The annular space between the inner surface of the shaft 6 and the inner surface of the shaft 6 is divided into one half, and a large number of liquid passage holes 13 are perforated in the pipe wall of the liquid feeding tube 8, which corresponds to one half, and the outer half thereof is pressurized. The liquid supply chamber C becomes the liquid supply chamber C, the other side is a sealed wall, and the outer half of the wall becomes the suction and drainage chamber ■.

The distal end of the partition member 11.12 has a rather wide seal 14.

The flange 9 provided on the tip side of the liquid feeding pipe 8 is connected to the dye liquid pressure feeding pipe 3.
An end flange 1 of a rotary cylinder 17 provided with a worm tooth ring 16 that is fitted onto the outside and meshes with a worm 15 that is driven from the outside.
8 is connected in the rotational direction by fitting a pin 19, and the other flange 10 is connected to a drain passage 31 fitted to the inner surface of the tank lid 5.
The presser shaft 27 is pushed out by the rotation of the bundle 32 outside the tank lid 5, and the presser 29 is attached to the flange 10.
A presser 29 is tightly coupled to the outside of the presser shaft 27 to seal the tip of the liquid feeding tube 8 and has a liquid drainage path 31, and is rotatably supported by a bearing 25 on the presser shaft 27.

The flanges 9 and 10 on both sides of the suction and drainage chamber (2) with respect to the sealed wall of the liquid feed pipe 8 are provided with fan-shaped liquid passage openings 22 and 2.
3 are respectively provided, and one liquid passage opening 22 is connected to the rotary cylinder 1.
The other liquid passage opening 23 coincides with the opening 24 provided in the end flange 18 of the processing tank body 2 and communicates with the end drainage passage 30 of the processing tank body 2, and the other liquid passage opening 23 coincides with the opening of the holding tool 29 and communicates with the drainage passage 30 of the processing tank main body 2. 31.

Reference numeral 33 denotes a roller of the cart supporting the beam B, which rolls on the rail 34 to move the beam B into and out of the processing tank, and also prevents the porous hollow winding shaft 6 from rotating due to the support by the cart. It is something that is pending.

When the tank lid 5 is closed, it is closely fixed to the processing tank main body 2 by a presser frame 35.

Further, the drain passage 31 of the tank lid 5 is communicated with the hollow shaft 37 of the hinge 4 through the outflow pipe 36 on the outer surface of the lid, and the lower hollow pipe 38 of the hollow shaft 37 is connected to the end of the drainage passage 39. They are fitted and connected so that they can move freely.

Each drain passage 30.39 has a flow control valve 40.41, respectively.
via heat exchanger 42. Pump 439. The liquid passes through the liquid feeding pipe 44 to the processing liquid pressure feeding pipe 3, forming a liquid circulation path in the direction of the arrow that communicates with the processing tank body 2.

A pressure adjustment tank 45 is provided at the top of the treatment tank body 2 and is connected to a source of pressurized steam or compressed air. It is connected to the tank to adjust the pressure inside the tank and collect and eliminate bubbles escaping from the workpiece F.

20 is a drain pipe provided on the lower surface of the processing tank main body 2.

Since this high-temperature and high-pressure beam processing machine has the above-mentioned structure, the object to be processed F is wound around the porous hollow winding shaft 6 which has a liquid feeding pipe 8 in the processing tank, and the object is inserted as shown in the figure. Then, the tank lid 5 is closed, and a processing liquid injection device (not shown) in the processing liquid circulation system injects the processing liquid so that the upper surface of the object F wrapped around the beam B in the processing tank is below the liquid level. The processing solution is supplied to a certain level, and while applying a predetermined solution temperature and atmospheric pressure, the processing solution is circulated under pressure, and the processing solution is pressurized and distributed from the inside to the outside through the wound layer of the object to be processed F, and the processing solution inside the outside. The suction flow is sequentially moved over the entire circumference of the object to be processed F according to the rotation of the liquid feeding pipe 8, thereby proceeding with uniform processing.

At this time, the opening degree of the flow rate control valves 40 and 41 provided at 30 and 39 communicating with both sides of the suction and drainage chamber This aims to make the processing uniform in the direction of the winding axis.

In this embodiment, the liquid feeding pipe 8 having the partition members 11 and 12 is rotated and the porous hollow winding shaft 6 around which the processed material F is wound is fixed. However, the liquid feeding pipe 8 is fixed, It is also easy to design the porous hollow winding shaft 6 to rotate.

Furthermore, when the tank lid 5 is closed and tightened, the outflow pipe 36 on the outer surface of the lid from the drain path 31 provided in the tank lid 5 is directly connected to the drain path 39 connected to the heat exchanger 42. You can also get it.

FIGS. 4 and 5 show an embodiment thereof. In the embodiment described above, the outflow pipe 36 on the outer surface of the lid was provided horizontally toward the hinge 4, but it was provided so as to face vertically downward. The lower end of the outflow pipe 36' is bent so that the open end can abut the drain passage 39 located on the same plane as the surface of the tank lid 5 in close contact with the tank body 2, and the holding frame 35 of the tank lid 5 is bent. When the claws 35' of the holding frame 35 engage and press the circumferential protruding edge 5' of the tank lid 5 to tighten the tank lid 5 to the tank body 2, the outflow pipe 3 is rotated.
A claw piece is provided on each of the 6' end and the drain path 39 end that abuts this, so that the two pipe ends are closely connected by rotation of the tightening ring 50. At this time, the holding frame 35 and The tightening tank 50 is meshed with and rotated by sector gears 51 and 52 provided on the respective peripheries, so that the tank lid can be opened and closed and the drain channel can be opened and closed at the same time. This is what I did.

As explained above, according to the present invention, the internal suction flow in the pressure flow treatment of the processing liquid to the object layer in the high-temperature high-pressure beam liquid processing machine can be made uniform in the winding axis direction. One side of the suction and drainage path is provided in the tank lid to create a liquid flow path, which avoids an increase in the internal volume of the processing tank and streamlines the liquid circulation piping. The effect of improving the practicality of the machine is significant.
