Abstract

PURPOSE:To remove a non-volatile solution only over the necessary length of the end part of a filter material, by supplying a washing liquid to the end part of the hollow filter material impregnated with the non-volatile solution by utilizing centrifugal force. CONSTITUTION:In washing the end part of a hollow filter material, a liquid separation apparatus 1 having pouring jigs 5 attached to both ends thereof is fixed on a rotary table 10 by a clamp 12 while a pot 8 and each pouring jig 5 is connected by tube 4 and a predetermined amount of the washing solution is introduced into the pot 8 from the pouring orifice 8a thereof. In this state, a motor is started to equally rotate the rotary table 10 and the pot 8 and the washing solution in the pot 8 is flowed into the pouring jig 5 by centrifugal force to wash and dissolve the non-volatile solution allowed to impregnate the filter material 2. Because the amount of the washing solution is preset, said washing solution is flowed into the hollow filter material 2 only to the position of a seal surface 7 and, because centrifugal force is acted, there is no penetration into the interior from the seal surface due to a capillary phenomenon.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an end treatment method and an end treatment device for sealing the ends of the furnace material with an adhesive in a liquid separation bag using a hollow furnace material. .

When the solvent is separated from the stock solution by reverse osmosis, ultrafiltration, or microfiltration, and the stock solution is concentrated and purified, a liquid separation device using a hollow furnace material such as a tubular membrane or a hollow fiber membrane, that is, a module is used. is being used.

Structures of the above modules have been proposed depending on the application, but a typical one is one in which a large number of hollow furnace materials are bundled together, their ends are aligned, and both ends of each group of hollow furnace materials are left open. It has a structure in which the end peripheral wall is sealed with resin and the bundle is housed in a cylindrical case.

By the way, for the liquid separator as described above, it is essential for performance to completely seal the ends of the hollow furnace material group with adhesive, but the actual gluing work is extremely difficult, and the liquid separator Currently, this is a major bottleneck in production.

In order to solve the above-mentioned problems, this invention utilizes centrifugal force to seal the ends of the hollow furnace material group, and with the centrifugal force acting on both ends of the hollow furnace material group, the hollow furnace material group is placed inside the cylindrical case. We tried a method in which a sealing adhesive was press-fitted into the hollow furnace material, and the adhesive penetrated into the sponge layer of the hollow furnace material and was allowed to harden.

However, in order to maintain its performance, the hollow furnace material, which is a permeable membrane, is generally kept in a wet state with a non-volatile solution until it is used. It was found that the solution was present at the edges and inhibited the infiltration of the supplied adhesive into the membrane, resulting in incomplete sealing.

As a result, in order to seal the ends of a group of hollow furnace materials using centrifugal force, it is sufficient to remove the nonvolatile impregnating solution to facilitate the infiltration of the resin adhesive. Even if you immerse it in a cleaning solution to clean only the ends, the capillary action of the sponge layer will cause the cleaning solution to reach several times the required length, making it impossible to use a non-volatile solution to cover only the required length of the ends. Since it is impossible to remove the non-volatile solution by the required length of the end, sealing the end using centrifugal force requires the development of a means that can remove the non-volatile solution by the required length of the end.

This invention was made in view of the above-mentioned points.The hollow furnace material group is impregnated with a non-volatile solution, and only the required length is effectively reduced using a cleaning solution and centrifugal force. It is an object of the present invention to provide a method for treating the end of a furnace material, which can be removed in a short period of time, and in which a cleaning solution can be supplied and discharged without any trouble during the action of centrifugal force, and a treatment apparatus for carrying out this treatment method.

The structure of this invention consists of a cylindrical case containing a large number of hollow furnace materials with their opening ends aligned in parallel, and a pot containing a cleaning solution connected to the case, which is placed on a rotary table and centrifuged. The solution is supplied to and discharged from the end of the cylindrical case by changing the centrifugal force of the solution by adjusting the position of the pot, and the end of the hollow furnace material is washed with the solution to elute the non-volatile solution. Embodiments of the present invention will now be described with reference to the accompanying drawings, in which the adhesive can be impregnated into the end layer of the furnace material by centrifugal force during discharge.

As shown in FIG. 1, a liquid separation device 1 l manufactured by horizontal centrifugal casting has two groups of hollow furnace materials with their open ends aligned in parallel and housed in a cylindrical case 3. A casting jig 5 to which a cleaning solution feeding tube 4 is connected is attached to both ends of the cylindrical case 3, and a permeate extraction nozzle 6 is provided on the peripheral wall of the cylindrical case 3. The outer periphery 1 of the hollow furnace material 2 from the nozzle 6 to the open end is a sealing surface 7 with a resin adhesive.

The liquid separation device 1 and the pot 8 containing a solution for washing and eluting the non-volatile bath liquid impregnated into the hollow furnace material 2,
It is placed on a rotating table 10 that constitutes the centrifugal force generating mechanism 9.

As shown in FIG. 2, the liquid separator 1 is mounted on the rotary table 10 with a jig 12 so that its center point coincides with the axis of the rotation @11 that supports the rotary table 10. The pot 8 is identified in a horizontal arrangement, and the pot 8 is placed on the rotary table 10, and the sliding table 1 is placed near the end of the carrier 1j of the liquid separation device ftl.
3, is movable along the axial direction of the liquid separation device 1, and is connected to the casting jig 5 through a liquid feeding tube 4.

Centrifugal force acts on the liquid separation device 1 and the cleaning solution in the bot 8 due to the rotation of the rotary table 10, and the centrifugal force acting on the cleaning solution changes as the rotation shape changes due to the movement of the pot 8. As shown by the solid line in Figure 2,
By setting the turning radius at a position /JN smaller than the end of the liquid separator 1, the solution can be supplied into the casting jig 5.
Conversely, as shown by the dashed line in the figure, if the radius of gyration is made larger at the end of the liquid separator i1, the cleaning solution in the casting jig 5 can be discharged and collected into the bot 8.

The means for moving the bot 8 placed on the rotary table 10 is formed using a differential gear mechanism 14 interlocked with the rotary shaft 11.

As shown in FIGS. 3 and 411, this difference@gear mechanism 14 has a bevel gear 15 solidly integrated with the rotating shaft 11 and a rotating #411.
] It moves with the bevel gear 16 and the bevel gear 17 for the metal differential, which are mounted so as to be free with respect to the rotary shaft II, and supports the A$2 gear 17 for the differential so as to be free to rotate. A ring-shaped worm gear I9 is attached to a horizontal shaft 18, and the worm gear 19 is attached to a shaft 21 + supported by a gear case 20.
When the worm 22 is meshed with the worm 22 attached to the rC and rotated by the handle 23 provided at the tip of the shaft 21, the worm gear 19 rotates and revolves around the worm gear 19, and the bevel gears 15 facing each other vertically. There is a difference in rotation between and 16.

A vertical shaft 24 is rotatably arranged on the side of the rotating shaft 11, and is interlocked with the rotating shaft 11 by a pair of gears 25 and 26 in which the vertical shaft 24 meshes with a bevel gear I6 of 7 lees.
A chain wheel 27 fixed to the upper end of the differential gear mechanism I4 and a chain wheel 28 attached to the upper part of the rotating shaft 11 so as to be rotated once are interlocked by a checker 729, and this chain wheel 28 is connected to the final rotation in the differential gear mechanism I4. It is a moving member.

An arm 3° projecting in the radial direction is attached to the chain wheel 28, and the tip of this arm 3o and the sliding base I3 of the bot 8 are interlocked by a ring 31, and the rotating base 10 and the chain wheel 28
When a difference occurs in the rotation of the slide table 1, the arm 30 swings and the slide table 1
3 will be moved.

Next, a method for cleaning the ends of the hollow furnace material group will be explained.

First, the liquid separation device 1 with the casting jig 5 attached to both ends is fixed on the rotary table lo with the clamp 12 as shown in FIG. Connecting.

Next, a predetermined amount of cleaning solution is poured into the pot 8 located at the solid line position in FIG. 2 through the spout 8a, that is, an amount corresponding to the volume from the sealing surface 7 to the end seal shown in FIG.

At this time, the tube connection port of the casting jig 5 is set higher than the liquid level of the bot 8 so that the cleaning solution does not naturally flow into the liquid separation device 1.

When preparations are complete, start the motor and move the rotating shaft 11 to the second position.
When rotated clockwise in the figure, the rotary table 10 and the bevel gear 15 rotate together, and the bevel gear 16 rotates in the opposite direction via the bevel gear 17. It is transmitted to the chain wheel 28 at the final position via the vertical shaft 24, the chain wheel 27, and the checker 729.

Here, if both the gears 25, 26 and the chain wheels 27, 28 are made to have the same size, the rotation speed of the chain wheel 28 will be equal to that of the rotating shaft 11, that is, the rotating table 10, and the direction of rotation will also be the same.

Therefore, the bot 8 does not move from the position indicated by the solid line in FIG. The liquid flows into the casting jig 5 located in a large position through the injection tube 4, and the ends of the hollow furnace materials 2 are immersed to wash and dissolve the non-volatile generation solution impregnated into the hollow furnace materials 2. Ru.

Since the amount of cleaning solution is set in advance, it only flows into the two groups of hollow P materials up to the sealing surface 7 shown in Fig. 1, and since centrifugal force is acting on the two groups, one capillary There is no occurrence of inward penetration from the sealing surface 7 due to this phenomenon.

After washing for a certain period of time, the handle 23 is turned to rotate the worm gear 19, the bot 8 is moved to the position indicated by the dashed line in FIG. 2, and the solution after washing is collected into the pot 8.

That is, when the worm gear 19 is rotated, the differential bevel gear 1
7 revolves around its axis, and the amount of displacement due to this revolution is the bevel gear 161. Gears 25, 26, vertical shaft 24 chain wheel 27 and check 7
29 to the chain wheel 28, and the chain wheel 28 and the rotating/base l
A difference occurs in the rotation of O, and as a result, the arm 30 swings,
Bot 8 will be moved using ring 31.

In this way, the bot 8 can be moved by simply rotating the handle 23 from the outside while the rotary table IO is rotating. The removal of the non-volatile solution by washing from the end to the sealing surface 7 ensures that the adhesive is impregnated into the above-mentioned position.

Note that the ends can be sealed after cleaning by using the same equipment and method as described above, and by using a sealing resin adhesive instead of the cleaning solution. In addition, the embodiment shown in FIG. 5 is designed to further improve the cleaning effect. 1, the bolts 41 and 42 are respectively arranged at the movement points, and are interlocked via the chain wheel 28, arm 30 and ring 31 so that the bolts 41 and 42 move in opposite directions, and one of the bolts 41 The other bot 42 is connected to the casting jig 5 by a liquid feeding tube 43, and the other bot 42 is connected to a hole 45 of an over 70 provided at a position corresponding to the sealing surface on the peripheral wall of the cylindrical case 3 by a liquid feeding tube 44. There is.

To perform cleaning, first pour a cleaning solution several times the cleaning volume into one of the pots/41, and when the turntable 10 is rotated, the cleaning solution flows from the tube 43 into the casting jig 5. It flows into the other bot 42 through the overflow hole 45 and through the tube 44 .

Next, rotate the handle 23 to connect the rotating base lo and the chain wheel 28.
When the rotation of the pots 41 and 42 is moved to the position indicated by the dashed line in FIG. After cleaning the ends of the second group of materials, they are returned to one pot 41.

In this way, the cleaning solution flows back and forth between the two bots 41 and 42 to clean the ends of the two groups of hollow P members, so that the cleaning effect is extremely large.

As described above, according to the present invention, a centrifugal force is applied to the cleaning solution and the cylindrical case in which a large number of hollow P materials are collected and housed in parallel, and the cleaning solution is supplied into the cylindrical case. Since the solution is discharged after cleaning only the end of the P material to be sealed, the nonvolatile solution impregnated into the hollow P material can be removed over the required length of the end. Therefore, it is possible to reliably impregnate only the end membrane layer of the hollow P material with adhesive, and the end portions of the hollow P material group can be cleaned efficiently and with high precision. Productivity is greatly improved.

In addition, the cleaning solution storage pot mounted on the rotating table is moved in conjunction with a differential gear mechanism linked to the rotating shaft, making it easy to move the storage pot even during centrifugal force during rotation. The centrifugal force can be changed by
Supply and discharge of cleaning solution can now be carried out safely.
