Problems solved by technology

[0003] The electrodialysis separator is an important structure in the electrodialysis technology. In the prior art, the electrodialysis liquid distribution channel and the plate frame of the electrodialysis separator are integrally formed, and the liquid flow channel can only be set on the surface of the electrodialysis liquid distribution channel. It is easy to cause collapse under pressure, block the liquid flow tank, poor sealing, and easy to leak; and additional process of digging liquid flow channels is required
The existing liquid distribution channel cannot be injection molded at one time, and the production efficiency is low

Embodiment 1

[0035] like Figure 1 to Figure 7 As shown, an electrodialysis separator provided in this embodiment includes a plate frame 13, liquid guide holes 14, a partition screen 15, and a liquid distribution channel 100. The upper and lower ends of the plate frame 13 are provided with liquid guide holes. 14. There is a cavity 16 in the middle of the plate frame 13. The liquid guide hole 14 is communicated with the cavity 16 through the liquid distribution channel 100. The partition screen 15 is arranged in the cavity 16. Two pieces 2, the inner side wall of the first piece has nine liquid flow grooves 5, the first piece and the second piece are snap-fitted, after the snap-fit, a sandwich liquid flow channel 6 is formed between the first piece and the second piece. In this way, the sandwich liquid flow channel 6 is located in the interior of the water distribution flow channel 100 instead of the surface, which can effectively avoid the collapse or blockage caused by the pressure of the...

Embodiment 2

[0044] like Figure 8 and Figure 9 As shown, the difference between this embodiment and the first embodiment is that the inner side walls of the first sheet 1 and the second sheet 2 both have nine liquid flow grooves 5 .

Abstract

The invention discloses an electrodialysis partition plate and belongs to the technical field of electrodialysis, the electrodialysis partition plate comprises a plate frame, liquid guide holes, a partition net and a liquid distribution runner, the liquid guide holes are formed in the two ends of the plate frame, a cavity is formed in the middle of the plate frame, the liquid guide holes are communicated with the cavity through the liquid distribution runner, the partition net is arranged in the cavity, and the liquid distribution runner is communicated with the partition net. The liquid distribution flow channel comprises a first piece and a second piece, a plurality of liquid flow grooves are formed in the inner side wall of the first piece and / or the second piece, the first piece and the second piece are matched in a clamped mode, and after clamping, a sandwich liquid flow channel is formed between the first piece and the second piece. The electrodialysis partition plate, the liquid distribution flow channel and the plate frame are not integrally designed and can be independently produced, the collapse or blockage problem caused by pressing of the sandwich liquid flow channel can be effectively avoided, the sealing performance is improved, and leakage is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of electrodialysis, and in particular relates to an electrodialysis separator. Background technique [0002] The method of separating different solute particles by the selective permeability of semipermeable membrane is called dialysis. When dialysis is performed under the action of an electric field, the phenomenon that the charged solute particles in the solution migrate through the membrane is called electrodialysis. The technology of purifying and separating substances by electrodialysis is called electrodialysis. It is a new technology developed in the 1950s. It was originally used for seawater desalination and is now widely used in chemical industry, light industry, metallurgy, papermaking, medicine Industry, especially the preparation of pure water and the treatment of three wastes in environmental protection are the most important, such as acid and alkali recovery, electroplating waste liquid treatm...
