[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing a separation membrane element using a separation membrane, and more particularly to a method for manufacturing a separation membrane element which surrounds a laminated member of a separation membrane unit and a permeate flow path material around a water collecting pipe. Related to the device.

2. Description of the Related Art A stock solution supplied with a stock solution as a fluid separation membrane element used in a reverse osmosis device, an ultrafiltration device, a microfiltration device, etc., and further used in a fluid separation device applicable to a gas separation device. Spiral type surrounding a unit consisting of a flow channel material, a separation membrane that separates the undiluted solution, and a permeate flow channel material that permeates the separation membrane and separates the undiluted solution into the collection tube. Are known.

A spiral-type separation membrane element is configured, for example, as shown in FIG. In the fluid separation membrane element 50 shown in FIG. 5, a laminated member 54 composed of a raw liquid flow path material 51, a separation membrane 52, and a permeate flow path material 53 is wound around a water collecting pipe 55 in a roll shape. An end plate 58 through which raw water 57 can pass and an end plate 60 through which concentrated water 59 can pass are arranged on both longitudinal sides of the body 56.
A seal material 61 is attached to 8 and 60. Permeated water 62
Is sent out from the water collecting pipe 55. The whole is housed in a pipe-shaped pressure vessel (not shown), and the seal between the end plates 58 and 60 and the inner peripheral surface of the pressure vessel is sealed.
The fluid separation membrane elements 50 shown in FIG. 5 are connected in the longitudinal direction by the required number as necessary.

In the assembly of such a separation membrane element 50, the formation of the laminated member 54 and its surrounding around the water collecting pipe 55 are conventionally performed as follows. As shown in FIG. 6, a single-wafer separation membrane 52 is folded in two so as to sandwich the undiluted liquid flow path material 51 therebetween, thereby forming a separation membrane unit 63. The separation membrane unit 63 and the permeate flow path material 53 are alternately stacked on the upper surface 53a, and the permeate flow path material 53 located on the upper layer side is provided.
Are sequentially joined to the permeate flow path material 53 located on the lower layer side to form a laminated member 54 having the uppermost layer as the permeate flow path material 53b. The distal end of the permeate flow path material 53a is wound around the water collecting pipe 55 by hand winding with the leading end thereof being wound.

[0005]

However, in the manufacture of the separation membrane element as described above, when the laminated member 54 is wound around the water collecting pipe 55, the leading end of each of the permeated liquid flow path members 53 which are sequentially joined. 65 may be turned up, and in some cases, the end may be wound with the tip folded. If the winding is performed while the tip is folded, not only is it difficult to form the final wound body 56 into a predetermined cylindrical shape, but also an undesirable flow occurs at the folded portion, and the performance of the separation membrane element is reduced. May be impaired. Conventionally, in order to avoid such inconvenience, the winding is performed while holding the tip 65 of each permeated liquid channel material 53 by hand at the time of winding, but the workability is poor, and a long time is required for the winding. There is a problem that requires.

Further, as shown in FIG. 6, the uppermost layer is formed so that the permeated liquid channel material 53b is formed longer, and is disposed so as to cover the tip 65 of each permeated liquid channel material 53 in the middle. Tip 65
Although there is a method of preventing the folding of the permeate, the uppermost layer of the permeate channel material 53b and the lowermost layer of the permeate channel material 53a are wound adjacent to each other in the state of the envelope 56. Consequently, the amount of material used as the entire permeate flow path material is wasted. In the first place, the uppermost layer of the permeated liquid flow path material 53b is provided to hold the form of the portion of the laminated member 54 of the lower layer, and is not required for the function of the separation membrane element. If the omission work is possible even if it is omitted, that is particularly desirable in terms of cost.

An object of the present invention is to focus on the problems and demands described above, and to prevent the leading end of each permeated liquid flow path material from being folded when winding the laminated member around the water collecting pipe, thereby performing a surrounding work. Separation membrane that can be simplified and shortened in time, can eliminate the permeate flow path material in the uppermost layer of the laminated member, can reduce cost, and can be configured as an automated device An object of the present invention is to provide an element manufacturing apparatus.

[0008]

In order to solve the above-mentioned problems, an apparatus for manufacturing a separation membrane element according to the present invention forms a single-piece separation membrane by folding it in two so as to sandwich a stock solution flow path material therebetween. The separated membrane unit and the permeate flow path material are alternately overlapped, and a laminated member in which the tip of the permeate flow path material located on the upper layer side is sequentially joined to the permeate flow path material located on the lower layer side,
An apparatus for manufacturing a separation membrane element in which a leading end of a lowermost layer of a permeated liquid flow path material is wound around a water collecting pipe with a starting point being wound, wherein the laminated members are sequentially joined when the laminated member is wound around the water collecting pipe. It is characterized by having a means for pushing the front end portion of the permeate flow channel material onto the permeate flow channel material of the lower layer.

In the apparatus for manufacturing a separation membrane element, the pushing-in means may be constituted by a free roller or a sliding guide plate. Also, the pushing-in means only needs to be placed at the pushing-in position when pushing-out operation is necessary for the tip of each permeated liquid flow path material, so that the pushing-in means moves forward and backward with respect to the pushing-in position. Preferably, it is provided as possible. Furthermore, since the position of the tip of each permeated liquid flow path material to be subjected to the pushing operation changes as the winding of the laminated member around the collecting pipe progresses, an appropriate pushing for the pushing operation is performed. It is preferable that the pushing-in means is floatingly supported by a spring or a cylinder device so that the pushing-out operation position can be automatically adjusted to an optimum position while maintaining the pressure.

In the apparatus for manufacturing a separation membrane element according to the present invention as described above, when the laminated member is wound around the collecting pipe, the leading end of each of the permeated liquid flow path materials is bent by the pushing means. It is sequentially pushed so as not to occur and along the surface of the lower layer of the permeated liquid flow path material, and is wound around the collecting pipe in the pushed-out state.
Therefore, it is not necessary to press the tip of each permeated liquid flow path material by hand, which greatly simplifies the wrapping operation, shortens the wrapping time, shortens the tact time, and automates the operation. Will be possible.

In addition, since folding is reliably prevented,
Conventionally, the uppermost layer of the permeated liquid flow path material of the laminated member, which has been provided to prevent the occurrence of inconvenience such as folding, becomes unnecessary, and the labor for laminating the uppermost layer of the permeated liquid flow path material is eliminated, so that the tact time is further reduced. Can be reduced, and the cost can be reduced because the amount of the permeated liquid channel material used is reduced.

It has become. On the swash plate 3 kept in the horizontal posture, the laminated members 6 laminated on another place, for example, on a laminating cart (not shown) are transferred.

The laminating member 6 alternately overlaps a separation membrane unit 9 formed by folding a single sheet separation membrane 7 in two so as to sandwich a stock solution flow path material 8 therebetween, and a permeate flow path material 10. The upper end of the permeate flow path member 10 is sequentially joined to the lower end of the permeate flow path member 10. One end of the lowermost layer of the permeated liquid channel material 10a is formed longer than the other permeated liquid channel materials 10. The uppermost layer of the permeated liquid channel material as shown in FIG. 6 is not provided.

A pipe receiver 12 is provided on the front end side of the swash plate 3, and a water collecting pipe 13 is disposed thereon. The tip of the lowermost layer of the permeated liquid flow path material 10a is fixed to the water collecting pipe 13 by bonding or the like, and is prepared for the next winding operation. In this state, as shown in FIG. 1, the leading end 11 of each of the permeated liquid flow path materials 10 sequentially joined on the lowermost layer of the permeated liquid flow path material 10a, It may be curled up.
