Description

Technical Field

[0001] The utility model relates to the technical field of EDI electric desalination, in particular to an ultrapure water EDI continuous electric desalination device. Background Art

[0002] Ultrapure water EDI continuous electric desalination equipment is a new type of ultrapure water treatment technology that combines continuous ion exchange and electric reaction technology. Compared with traditional mixed bed, reverse osmosis and other processes, EDI equipment does not require the use of chemical reagents, but only requires electrochemical treatment to obtain high-quality ultrapure water.

[0003] Publication number CN 219489687 U discloses an EDI electro-desalination treatment device, in which a mounting membrane is arranged on a mounting frame, the mounting frame is connected to the outer shell by insertion, and is positioned by means of the cooperation between a card block and a slot. During subsequent disassembly, the mounting frame can be pulled out from the inner part of the outer shell by canceling the cooperation between the card block and the slot, so that the mounting membrane can be replaced conveniently.

[0004] When replacing the negative membrane and the positive membrane in the above-mentioned prior art, it is necessary to rotate the four rotating rods in sequence to drive the moving bar to move in a directional manner inside the fixed box, so as to cause the card block to be pulled out from the slot for replacement. This operation method requires rotating the four rotating rods in sequence, which is cumbersome to operate. In addition, during installation, it is necessary to push the fixing bar with force to ensure that the fixing bar and the sealing gasket are in close contact with each other to ensure their sealing. When the fixing bar and the sealing gasket are in close contact, after the card block is embedded in the slot, when the fixing bar is loosened, the distance between the card block and the slot may cause the fixing bar and the sealing gasket to no longer be in close contact, resulting in poor sealing. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In view of this, the purpose of the utility model is to propose an ultrapure water EDI continuous electro-desalting equipment.

Moreover, during installation, it is necessary to push the fixing bar with force to ensure that the fixing bar and the sealing gasket are in close contact with each other to ensure their sealing. When the fixing bar and the sealing gasket are in close contact, after the card block is embedded in the slot, when the fixing bar is loosened, the distance between the card block and the slot may cause the fixing bar and the sealing gasket to no longer be in close contact, resulting in poor sealing.
