Abstract

PURPOSE:To equally distribute and supply a predetermined amount of resin to a module end part, in preparing a hollow yarn type or a tubular separation apparatus by centrifugal injection molding, by injecting the resin from a freely tiltable pot in the vicinity of said module end to perform injection molding. CONSTITUTION:The emitting port 20 of a pot 2 is connected to a case 12 and a predetermined amount of injection molding resin is put in the pot 2. In the next step, a module rotor 1 is horizontally rotated by driving a rotary means to move the resin in the pot 2 as shown by a fine line A and said pot 2 is inclined to an external direction against the force of a spring 4 around a pivot rotary end 22. The pot 2 is again brought to a stationary state by a stopper 5 and the resin is moved to the upper part of the pot 2 to be flowed into the end part of the case 12 from the emitting port 20 through an arranged pipe 3. Because the rotor 1 is rotated until the injected resin is perfectly cured, the injected resin is positioned at the predetermined end part in the case 12 and is not flowed out therefrom and air bubbles are not also left.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for manufacturing a tubular or hollow fiber membrane liquid separation device by centrifugal casting.

A liquid separation device such as a reverse osmosis device or an ultrafiltration device can be used to separate the solvent and solute from the stock solution.

As these liquid separation devices, tubular modules and hollow fiber modules are known. In this tubular module, as shown in FIGS. 1(=) and (b), a plurality of separation tubes 101 are housed in parallel in a cylindrical case 100.The separation tube 101 is made of non-woven fabric G102, and its inner surface is One separation tube lO1 provided with a membrane 103 is a case 100.
It is fixed in a liquid-tight manner by injection hardening resin 104 at both ends. Further, piping joints 105 are attached to both ends of the case 100 from the outside by adhesive or screws. The hollow fiber type module is shown in FIGS. 2(a) and (b).

A plurality of hollow fiber separation membranes 106 are bundled together into a cylindrical case 71.
It was stored in 07. Similarly to the upper audience tubular module, the 1"4 membrane 106 is fixed in a fluid-tight manner at both ends of the case 107 with injection hardening resin 108 to form a module.

The above-mentioned cured resin injection step is one of the most important steps in assembling the liquid separation) 11 device. A known method for injecting the curable resin is so-called centrifugal casting, in which a module is placed horizontally and the resin is injected using the centrifugal force generated by rotating the module. According to this method, the gaps between the nine tubular separation tubes or the gaps on the hollow fiber separation membrane can be completely filled with resin and the separation tube ends or molecules J
No liquid leakage from the edge of the IC membrane.

By the way, when casting multiple modules at the same time 2.
One resin reservoir or pot installed in the center of the first cycle was connected to each module end through piping, and the required amount was evenly distributed and injected to each module end through this connecting pipe. However, it is extremely difficult to inject the required amount of resin evenly into the ends of each module.

Although it is possible to take measures such as adjusting the piping resistance, it is technically extremely complicated and impractical.It is also possible to arrange the same number of pots according to the number of injection points.

Since it is difficult to supply resin to the pot that rotates with the module, it is necessary to drain the resin once) when the module is stopped.
The process of supplying and then starting operation is necessary, so that the resin flows unduly to the end of the module while the predetermined centrifugal force is reached, and the module does not reach the predetermined centrifugal force. The resin that has flowed into the end of the module ends up in the end trap and unnecessarily flows out and adheres to the outside of the case and separation membrane.

An object of the present invention is to distribute a predetermined amount of resin evenly to each module end. K provides a manufacturing device for a branch body segment device. Another object of the present invention is to provide an apparatus for manufacturing a liquid separation device in which the injected resin does not leak out or adhere to unnecessary parts of the separation tube, separation membrane, or its storage case. 1 Yet another object of the present invention is to
It is necessary to provide a manufacturing device for a liquid separation device that can be easily mass-produced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on its implementation and with reference to the drawings.

Device of the present invention 1-1. , #', 3 Figures (a), (b
), n yo'CFm 4 As shown in Figure VC, 1 rotating body 1
A rotating body l having a rotating means M such as a motor for rotating the rotating body accommodates or fixes in parallel at least one module made of resin. This rotating body (module iii) rotates nine times horizontally with the longitudinal direction of vIQ as the rotating part. Module/'10 is a tubular separation tube or hollow fiber separation membrane 11 of a predetermined length, both ends of which are closed by an appropriate method, and a cylindrical case 2 is loaded with TiC in parallel. A cover 13 is attached to both ends VC of this cylindrical case 12 to prevent the resin from leaking out after injection.

In the rotary body IK, the pots 2 that can be sealed are placed near the end directly or via the pedestal 21. The number of pots 2 arranged in the rotary body IK is: t −7 +/ 1
Two per tree. A discharge port 20 is provided at the top of this pot 2.
It has a discharge port 20 and is connected to a predetermined portion of the end of the pipe 31C and the fumodule/L'IO. The pot 2 is pivotally fixed at one end 22 on the rotating body 1 by a pin or the like.

The pot 2 can be rotated or tilted outward in the radial direction with respect to the rotation center 0 of the rotating body 1 using the pivot fixed end 22 as a fulcrum. In order for this rotation and tilting to occur smoothly, the pivot fixed end 22 is selected to be located outwardly and below the pot 2 with respect to the rotation center 0 of the rotating body 1.

Spring material 4 for controlling the rotational movement of the pot 2. For example, a tension spring is provided.

This spring material 4 has one end 41 attached to the rotating body 1 and the other end 42 attached to the bot 2, for example. One end 41 of the spring material 4
It is necessary that the position at which the spring material 4 is attached to the rotating body l be on the vertical iY passing through the pivot fixed end 22 of the bot 2, and the position at which the other end 42 of the spring material 4 is attached to the bot 2 is on the axis fixed end 22 of the bot 2. It is necessary to be as far away from the end 22 as possible and not on the perpendicular line Y. The setting position of the spring material 4 can be set in consideration of the shape of the bot, the physical properties of the resin to be handled, the required number of rotations, the centrifugal force to be obtained, the spring force of the spring material, etc. A stopper 5 for regulating the rotation of the bot 2 is provided at a predetermined position in the bot 20 rotation direction. The position of this stopper 5 can be set depending on the centrifugal force generated by the i rolling element 11C, the tilting angle of the bot 2 required for resin injection, and the like.

Using the apparatus of the present invention, the plastic molding of the module A/1 is carried out as follows: Connect the discharge port 2o of the bot 2 to the case 12 via the pipe 3. A required amount of room temperature curable casting resin is put into the bot 2 from the resin inlet 23 of the bot 2. Next, the centrifugal force r generated by the 0-rotating body ii, which horizontally rotates the module rotating body 1 by driving the 9-rotating means, is expressed by the following equation.

r--ω2r Here, W: weight of the rotating body and bot.

ω: Angular velocity.

r: radius of rotation.

g double force acceleration.

''The two equations express that the centrifugal force F increases in proportion to the square of the angular velocity ω.

The resin in the pot 2 gradually moves as the centrifugal force F is generated, and when a certain centrifugal force is reached, the liquid level will be indicated by the thin line A. The resin J does not reach the resin discharge port 20 provided at the top of the bot 2.

The bot 2 is controlled by the spring force of the spring material 4, and the number of revolutions of the zero-rotating body 10, which remains stationary, gradually increases.

When the centrifugal force increases accordingly, the bot 2 moves from the initial resting position which is the first stable position to the pivot fixed end 22 (together with the pedestal 21 1c) as a fulcrum and moves outward against the spring force of the spring sheath 4. While quickly rotating or tilting, the robot passes over the vertical Y in the unstable position within the time interval and comes into contact with the stopper 5. The bot 2 is at rest again at the stopper 5, which is the second stable position (11).

hold At this time, the tree 1 finger 11 in the bot is the outlet 20
The bottle containing the liquid moves to the upper part of the inside of 2, and the liquid level of the liquid becomes almost vertical as shown by the thin line B.The resin is good.

The body 1 flowing into the end of the case 12 from the discharge port 20 through the pipe 3 rotates and maintains a predetermined centrifugal force, so that the required amount of resin in the pot 2 flows into the case 12. Injected. After the resin is injected, the fourth body continues to rotate with a predetermined centrifugal force until the injected resin is completely cured. therefore,
The injected resin is located at a predetermined end of each nL tube 11 in the case 12 and never flows out from there. Air bubbles in the injected IR resin diffuse through the resin toward the center of rotation, so no air bubbles remain in the cast resin. .

In another embodiment of the device according to the invention, as shown in FIG. 5, a weight can be added to take advantage of this weight.

The weight 6 is integrally moved around the bolt 1-2, and due to the rotation of the two rotating bodies 1, its centrifugal force tilts the bolt 1-2 at a predetermined angle. In the case of ゛.

Compared to the above embodiment which does not use the main body 1, the centrifugal force increases by the weight of the main body υ6 even at the same rotation speed. It has the advantage of requiring less.

In either embodiment, the spring material 4 is adjusted and the initial rest of the bottle 2 is adjusted so that injection of resin can be started when the bottle 1-2 is tilted at a predetermined angle (when a predetermined centrifugal force is reached). It is important to set the distance between the liquid level of the resin in the pot F and the top surface in the pot at the position.
