Description

[Detailed description of the invention] The present invention relates to a cocoon processing device that prevents changes in the pressure receiving state of the cocoon layer depending on the position of the surface and eliminates uneven water content in the cocoon layer when performing patch-type cocoon processing in a single layer. The purpose of this is to enable the same process to be repeated as necessary.

Conventionally, cocoon treatment by batch-type vacuum percolation involves repeatedly reducing the pressure in the treated water and returning it to atmospheric pressure to impregnate the cocoon layer and cocoon cavity with moisture.
The cocoons that are immersed one by one are located deep or shallow in the water depending on their position in the lot, and each cocoon layer receives different pressures, and the cocoons located at the top and the cocoons located at the bottom differ in water content. This will cause spots.

The device of the present invention eliminates these drawbacks.

An example of implementation of the device of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a drum-shaped image processing container, which is horizontally supported by a frame 5 by bearings 4.4, with hollow shafts 3, 3 provided at the center of both side surfaces 2, 2 serving as supporting shafts.

A cocoon input and discharge lower is provided on a part of the circumferential side 6 of the image processing container 1,
An opening/closing lid 9 is attached to one side edge of the lid with a hinge 8.

An air bleed pipe 10 is attached to the top of the opening/closing lid 9, and a cam follower 11 is attached to the side of the opening/closing lid 9.

The rotating shaft 12 is inserted into the hollow shaft 3.
It is provided so that it can be rotated separately from the

A perforated plate 14 is supported on the rotating shaft 12 by a support member 13.

The perforated plate 14 has a flat plate shape extending in the diametrical direction of the drum-shaped cocoon container 1, and may be either a plate-like body with many small holes or a net-like body.

The perforated plate 14 does not come into contact with the inner wall of the image processing container 1, and the distance between the perforated plate 14 and the inner wall of the perforated plate is small enough that the surface on the perforated plate 14 is not sandwiched between the perforated plate 14 and the inner wall of the perforated plate.

Cheno wheels 15 and 16 are fixed to the hollow shaft 3 and the rotary shaft 12, respectively, and the hollow shaft 3 and the rotary shaft 12 are rotated by receiving power transmitted from a drive source (not shown).

Reference numeral 17 denotes a fork-shaped arm for opening and closing the opening/closing lid 9, which is supported by a shaft 18 and has a fork-shaped portion 19 at the tip thereof, into which a cam follower 11 is fitted when the image processing container 1 is erected.

Balance way on shaft 18) 20, Cheno foil 21
It is fixed.

The Cheno wheel 21 connects to the motor shaft 23 via the Cheno wheel 22.
It is connected to the Cheno foil 24 fixed to.

A cam plate 25 is fixed to the frame 5 and is provided so as to surround the image processing container 1. When the image processing container is rotated, the cam follower 11 comes into contact with the cam plate 25 to prevent the opening/closing lid 9 from opening.

Next, an image processing method using the device of the present invention will be explained.

Under the condition shown in FIG. 1, the motor shaft 23 (not shown)
Rotate the chain wheel 24, chain wheel 22. The shaft 18 is rotated counterclockwise through the chain wheel 21, and the fork arm 17 is rotated counterclockwise.

At this time, since the cam follower 11 of the opening/closing lid 9 is located within the fork, the opening/closing lid 9 opens centering on the hinge as the fork arm 17 rotates, resulting in the state shown in the dashed line in FIG. 1. The motor will stop rotating.

Then, a predetermined amount of the surface to be treated is introduced from the opened cocoon input and discharge lower.

At this time, since the perforated plate 14 is in the position shown in FIG. 2 in the image processing container 1, the surface to be processed is placed onto the perforated plate 14.

The treated water 26 fills approximately half of the image processing container.

Next, the opening/closing lid 9 is closed and air is extracted from the air bleed pipe 10 to reduce the pressure inside the image processing container 1, and the air in the cocoon cavity of the cocoon layer is sucked.

The degree of decompression varies depending on the type of surface, but 20 m of mercury
It should be about 500mm from m.

After that, rotate the motor (not shown) and rotate the chain wheel 1.
When the rotary shaft 12 is rotated through the shaft 6, the perforated plate 14 rotates via the support member 13 integrated with the coaxial shaft 12, and the treated cocoons on the perforated plate 14 also rotate, and the treated cocoons are submerged in the treated water 26. I will do it.

At this time, the valve of the air bleed pipe 10 is operated to introduce atmospheric air into the air bleed pipe to bring the inside of the image processing container 1 to atmospheric pressure.

Therefore, the treated water is forced into the cocoon cavity of the cocoon layer, which was in a reduced pressure state in the previous step, and the treated water is also introduced into the gaps between the lines of the cocoon layer filament.

Set the timer to maintain atmospheric pressure inside the image processing container.
After a predetermined time (10 seconds to 60 seconds) has elapsed, the valve of the bleed pipe 10 is closed, and the perforated plate 14 is rotated in the same manner as described above to remove the treated surface from the treated water.

Next, bleed air from the bleed pipe to a mercury column of 20 mm to 500 mm.
The cocoon layer and the inside of the cocoon cavity are dehydrated under moderately reduced pressure.

In the above process, the pressure is reduced in the atmosphere and atmospheric pressure in the water, but depending on the quality of the cocoon layer, it is possible to pressurize and reduce the pressure in both the air and water by appropriately selecting the time when the perforated plate rotates. .

The above process completes one cycle of image processing, but in the case of cocoons with thick cocoon layers or poorly unwound cocoons, it is difficult for water to penetrate inside the grains of the cocoon layer, so the above process may be repeated once or twice.

Next, by rotating the hollow shaft 3 together with the rotating shaft 12, the cocoon input and discharge lower of the image processing container 1 is directed downward.

At this time, the image processing container 1 rotates clockwise in FIG. 1 with the cam follower 11 in contact with the cam plate 25.
At the same time as the image processing container 1 is opened, the opening/closing lid 9 is opened as shown by the two-dot chain line in FIG.

Thereafter, the image processing container 1 turns in the opposite direction to return to the state shown by the solid line in FIG. .

As described above, the device of the present invention is a drum-shaped cocoon processing container equipped with an opening/closing lid having an air bleed pipe on the circumferential side, which is supported by a hollow shaft with its axis horizontal, and a cylindrical drum that extends in the diametrical direction. A flat perforated plate that divides the interior of the cylinder into two sections is spread in the diametrical direction of the drum-shaped cocoon processing container by a rotating shaft inserted into the hollow shaft, and does not come into contact with the inner wall of the drum-shaped cocoon processing container. Because of this support, depressurization treatment can be performed in either air or water by appropriately selecting the timing of air bleed and perforated plate rotation, and there is no difference between the two types of treatment surface immersed in the treatment water. Pressure treatment is carried out without generation, and each cocoon layer can be treated individually.
Depending on the quality of the steel, the same treatment can be repeated over and over again, so the treatment can be changed in a timely manner depending on the aspect of each lot.

Note that by connecting a pressure cylinder of carbon dioxide or the like to the bleed pipe and pressurizing carbon dioxide or the like into the image processing container according to the image quality, it is possible to chemically treat the cocoon layer and change the properties of the treated water.
