[0025] The specific implementation process of this utility model is as follows: When in use, the specific process of electrodialysis has been disclosed in the utility model patent with patent authorization announcement number CN222665532U, and will not be repeated here.

[0026] When the bipolar membrane 7 needs to be removed, simply rotate the rotary rod 81. The rotary rod 81 drives the rotating seat 82 to rotate, which in turn drives the retaining ball 86 to rotate. The retaining ball 86 rolls along the arc surface of the groove 87 and rolls into the rotating seat 82. The retaining ball 86 drives the slider 85 to move outward, which in turn drives the sliding rod 83 to move. The slider 85 can compress the first spring 84, which will eventually separate the retaining ball 86 from the groove 87 and rotate the rotating seat 82 by 90°. Then, the connecting plate 6 can be moved horizontally to pull it out of the housing 4, making it convenient for the maintenance and replacement of the bipolar membrane 7.

[0027] When it is necessary to flip the housing 4, pull down the lever 94. The lever 94 moves the support block 93 down, and the support block 93 slides along the guide rod 95 to compress the second spring 96. At the same time, the support block 93 moves the magnetic block 97 down. When the magnetic block 97 is attracted to the magnet 98, the support block 93 will move the insert block 92 down and separate it from the rotating column 3. Then, rotate the housing 4. The housing 4 drives the rotating column 3 to rotate and flip the housing 4. Finally, push the lever 94 up to reset the insert block 92 and insert it into the slot 91 in another position. This can limit the rotating column 3 and complete the flipping and fixing of the housing 4, which is convenient for backwashing the internal bipolar membrane 7. The operation is more convenient.
