Description

Device for manufacturing hollow fiber with covering yarn {Manufacturing Machine For Hollow Fiber Membrane Bundle With Covering Yarn}

The present invention relates to an apparatus for manufacturing a hollow fiber having a covering yarn, and to an apparatus for providing a covering yarn in a hollow fiber in order to maintain a gap between hollow fibers in a hollow fiber bundle.

Recently, in the automotive field, efforts to replace fossil fuels and internal combustion engines with batteries and motors have been made rapidly. In the case of adopting a secondary battery as a battery, there are numerous problems to be solved, such as a charging capacity that must be sufficient to travel a long distance, but a light weight and a short charging time are required. Therefore, there are many studies on the use of fuel cells using alcohol or hydrogen.

For example, a fuel cell using hydrogen has a longer mileage than a secondary battery, does not emit environmental pollutants at all, and hydrogen is produced from water, so there is no dye for energy depletion, and charging time is very long. There is a short advantage.

Fuel cells are classified into various types of fuel cells such as polymer electrolyte fuel cells, pull-up fuel cells, and molten carbonate fuel cells. Because it can be miniaturized, it is widely adopted in transportation equipment such as automobiles or small power generation systems.

In the case of a fuel cell for a polymer electrolyte, in order not to degrade its performance, a certain amount or more of moisture must be supplied to the polymer electrolyte membrane of the membrane electrode assembly to maintain a constant moisture content.

In order to humidify such a polymer electrolyte membrane, a fluid exchange membrane module of a humidification membrane type is used to supply moisture to a flowing gas using a polymer separator. The humidification membrane method is achieved by providing water vapor in the exhaust gas to the polymer electrolyte membrane by using a membrane that selectively permeates the water vapor contained in the exhaust gas, and using such a method can reduce the weight/miniaturization of the humidifier.

As disclosed in Patent Publication No. 2015-0078541, the humidifying membrane-type fluid exchange membrane module (A) is provided with a potting part (C) serving as an inlet and outlet through which exhaust gas or the like passes through the hollow fiber bundle (B) serving as a membrane. The potting part (C) is manufactured by impregnating the end of the hollow fiber with a liquid synthetic resin such as polyurethane, epoxy, or silicone resin, and then cutting it to seal the gap between the hollow fibers (see Fig. 1).

In addition, it is possible to maximize the efficiency of use of the hollow fiber bundle, which is a membrane, by securing the gap between the hollow fibers between the potting portions on both sides of the fluid exchange membrane. Is known.

In this case, it is difficult to arrange the spacer yarns in a uniform distribution between the hollow fibers, and there is a problem in that the use efficiency is not uniform due to the uneven distribution.

On the other hand, Japanese Laid-Open Patent Publication No. Hei 6-327905 discloses securing a gap between the hollow fibers by winding the circumference of the hollow fibers with a covering yarn as shown in FIG. 2. However, the hollow fiber is manufactured in a hollow shape, and in particular, the hollow fiber for a membrane to which the present invention is applied is a flexible material, so that when the covering yarn is wound as disclosed in Japanese Unexamined Patent Application Publication No. Hei 3-278821, it is shown in FIG. As with the shape, the hollow fiber is transformed into a curved shape by the tension of the covering yarn, and it is difficult to keep the shape continuously because the wound covering yarn is released when cutting the hollow fiber.

In the present embodiment, the hollow fiber is supplied from a roll or a pretreatment process in which the hollow fiber is supplied.

The hollow fiber 1 is supplied to the apparatus of this embodiment by a guide roller 10.

The supplied hollow fiber 1 is first supplied to the first passage part 20. The first passage part 20 is supported by the first frame part 30 and has a shape of a hollow shaft through which the hollow fiber 10 can pass.

A first disk 40 is rotatably installed in the first passage part 20. A gear is formed on the circumferential surface of the first disk 40.

In addition, a first bobbin mounting portion 50 as shown in FIG. 6 is provided on the front surface of the first disk 40 to mount the first bobbin 51 wound around the first covering yarn 2.

A first guide portion 60 is provided to guide the first covering yarn 2 drawn out from the first bobbin 51 toward the hollow fiber 1 side.

The circumference of the hollow fiber 1 advancing through the first passage part 20 is wound around the first covering yarn 2 that is released and rotated according to the rotation of the first disk 40. At this time, the first bobbin 51 is installed so that the first covering yarn 2 can be released very smoothly from the first bobbin 51, except for the fine tension generated while passing through the first guide part 60. No tension occurs.

Both sides adjacent to the point where the first covering yarn 2 drawn out from the first guide part 60 is wound around the hollow fiber 1, that is, before the first covering yarn 2 is wound, the hollow fiber 1 and the first Supporting a point adjacent to the first guide part 60 among the portions of the hollow fiber 1 wound by the covering yarn 2 can prevent the deformation of the hollow fiber 1 by the covering yarn.

The portion of the hollow fiber (1) wound by the first covering yarn (2) is a first to be described later when the first covering yarn (2) is wound by the support section (80) when entering the heating section (70) or when the second covering yarn (3) is further wound. 2 Supported by extension support.

The first extension support part 90 is manufactured in the form of a synthetic resin hollow shaft, and is mounted on the first passage part 20 to suppress sagging or deformation of the hollow fiber 2.

Since the first bobbin mounting portion 50 is installed on one front side of the first disk 40, the first disk 40 is affected by eccentricity when the first disk 40 rotates around the first passage portion 20. In order to reduce this, a counter weight portion 52 is provided to install a predetermined mass at a position symmetrical to the first bobbin mounting portion 50 of the first disk 40.

In this embodiment, the second covering yarn 3 is again wound around the hollow fiber 1 wound by the first covering yarn 2.

Even if the description of winding the second covering yarn 3 is omitted, those skilled in the art will fully understand through the description of winding the first covering yarn 2.

It is preferable that the winding directions of the first covering yarn 2 and the second covering yarn 3 are reversed.

To this end, it is preferable to rotate the rotational directions of the first and second disks 40 and 140 that rotate by receiving driving force from the motor 200 in opposite directions, and it is preferable that the rotational speed is also the same. .

7(a) shows a first drive transmission unit 210 for rotating the first disk 40, and (b) is a second driving transmission unit 220 for rotating the second disk 140 Is shown.

The first drive transmission unit 210 includes two gears 211 and 212 having the same radius, and the first disk 40 rotates according to the rotation of the reference numeral 211 gear receiving the driving force from the motor 200. .

The second drive transmission unit 220 rotates the second disk 140 according to the rotation of the 221 gear.

The first and second drive transmission units 210 and 220 have the same gear ratio with the first and second disks 40 and 140, so that the number of revolutions per minute is the same.

The heating unit 70 is for permanently changing the shape by heating the first and second covering yarns 2 and 3 mainly made of polypropylene (PP) or polyethylene terephthalate (PET), etc., and is about 190 degrees Celsius. It will supply a degree of hot air.

The heating unit 70 is composed of a heater and a fan, and it is possible to supply air by a pneumatic line in the field instead of a fan. It goes without saying that the heater must be controlled to maintain the temperature in the heating unit at a constant temperature by a temperature sensor.
