るべき提案はない。Problems that the invention aims to solve The important point here is that when the unit is attached to an electrodialysis tank, if the anode side and cathode side of the unit are mistaken, the dialysis machine will not function properly. For example, in the case of a three-chamber dialysis tank for desalting a very small amount of sample such as a liquid chromatography preparative solution, the internal structure of the tank includes an anode frame, an anion exchange membrane,
The desalting chamber frame, cation exchange membrane, and cathode frame must be arranged in this order, but if the unit is installed incorrectly, the sample to be desalted will have a high salt concentration. Furthermore, when desalting a large number of unspecified samples, such as desalting liquid chromatography preparative solutions mentioned above, it is desirable to use a new membrane for each sample, and for this reason, the unit must be attached and detached quite frequently. It will be done. Based on the above, in small-scale dialysis machines, the first
The second requirement is that the unit can be installed without error.
Although it is required that the unit can be easily attached and detached, there have been no proposals to date regarding this.

This electrodialysis cell structure prevents the unit from being installed correctly when the anode and cathode sides of the unit are reversed.Furthermore, by providing a handle on the unit, This makes it easy to put on and take off.

This will be explained based on the diagram.

法で簡単で加工できるため特に好ましい。 Figure 1 shows that by cutting out one corner of the bottom of the unit, the contact surface with the electrode frame is made in a non-linearly symmetrical shape.
Additionally, this is an example in which a handle is provided on the top of the unit. The unit is constructed by alternately stacking n membranes and n-1 chamber frames, placing gaskets with electrode frames on both ends, and joining them with adhesive, or by stacking the gaskets and chamber frames on each other with adhesive. Using thermoplastic resin as the material,
Part or all of the side surfaces are joined together by means such as thermal welding. The anode frame is provided with a recess that matches the shape of the contact surface of the anode frame of the unit, thereby preventing incorrect installation of the unit.
In other words, even if you try to install the unit in the wrong direction, the anode side and the cathode side, as shown in Figure 1, the shape of the recess on the anode side does not match the shape of the unit, so the unit will not fit completely between the electrode frames and will not be able to be installed. . Further, in FIG. 1, the anode frame is provided with a recess, but a recess that matches the shape of the cathode side contact surface of the unit may be provided on the cathode side, or may be provided on both the anode and cathode. In this way, making the contact surface of the unit with the electrode frame a non-linearly symmetrical shape
This is particularly preferred because it can be easily processed by cutting out a part of the surface perpendicular to the membrane of the unit.

を設けることはさらに好ましい。 Next, an example will be described with reference to FIG. 2 in which the shape of the contact surface with the electrode frame parallel to the membrane of the unit is line symmetrical but different on the anode side and the cathode side. FIG. 2 shows that the stepped portion 2 is formed so that the anode half and the cathode half of the unit have different shapes. This method can be carried out by using chamber frames with different shapes for the cathode side and the cathode side when manufacturing the unit, or simply by making only the gaskets connecting the electrode frames at both ends of the unit different shapes. In this case as well, incorrect installation of the unit can be prevented by providing at least one of the electrode frames with a recess that matches the shape of the contact surface of the unit, but in the example shown in Figure 2, the anode side, which has a smaller contact area with the unit, It is preferable to provide a recess, and it is even more preferable to provide a recess at both the positive and negative poles.

うにしたものである。 For an example of installing a handle on the unit, see Part 1.
As shown in FIG.
It can also be formed by cutting out a part of the electrode frame. In FIG. 3, there is no protrusion that can be used as a handle on the surface perpendicular to the membrane of the unit, but a notch is provided on the electrode frame side so that the unit can be pinched.

る。 Next, FIG. 4 shows an example of a cell for a three-chamber desalination apparatus. When the unit is thin, such as a cell for a three-compartment desalination device, it is more preferable to provide a concave portion in one electrode frame and a convex portion corresponding to the concave portion in the other electrode frame. This is very advantageous because it allows the unit to be tightened more completely and creates a pocket into which the unit can be inserted immediately when the electrode frame is loosened.

There is no particular restriction in this application. Furthermore, as shown in Figures 1 to 3, units that have both a desalination chamber and a concentration chamber require a concentrate supply port and a concentrate outlet, but there are no restrictions on the arrangement of these. isn't it.

であることが好ましい。 In the present invention, there is no particular limitation on the means for making the shape of the contact surface of the unit with the electrode frame line symmetrical. As shown in FIG. 1, the notch 1 on the side surface of the unit may be formed by cutting out one place, or conversely, by providing a protrusion. Furthermore, there is no particular limitation on the means for making the contact surfaces on the anode side and the cathode side different in shape. For example, the purpose can be achieved by simply making the shapes of the gaskets at both ends of the unit different between the anode and cathode sides. moreover,
The position of the handle is not particularly limited either, and may be determined depending on which direction the unit is to be attached to or removed from the dialysis cell. Regarding the relationship between the shape of the contact surface of the unit with the electrode frame and the shape of the concave portion of the electrode frame, it is desirable that the latter be 0 to 5 mm larger than the former.
This is because it is easier to attach and detach the unit if the size of the recess is slightly larger than the unit. The size of the unit is not particularly limited, but the number of chambers is 1 or more and 50 or less, and the number of membranes is 1 or more.
It is preferable that the conductive area per sheet be small-scale, 200 cm 2 or less.
