Description

Technical Field

[0001] The utility model belongs to the field of electrodialysis, and in particular relates to a pressing device for an electrodialysis membrane assembly. Background Art

[0002] Electrodialysis is a method of separating different solute particles by using the selective permeability of a semipermeable membrane. The phenomenon in which charged solute particles in a solution migrate through a membrane when dialysis is performed under the action of an electric field is called electrodialysis.

[0003] When assembling the electrodialysis membrane assembly, the membrane stack and the compression plate and other structures need to be compressed to ensure close contact between the structures. The existing electrodialysis membrane assembly compression device uses a hydraulic cylinder for compression operation, but the hydraulic cylinder has a limited stroke and cannot meet the compression operation of electrodialysis membrane assemblies of different thicknesses. The existing method is to stack enough pads to make up for the stroke, but this method requires the pads to be placed on the top of the hydraulic cylinder. There is a risk of pads falling during the stacking process and the hydraulic cylinder operation process, which is high risk. Utility Model Content

[0019] 3. The setting of the holding plate makes it convenient to take and place the beam.

[0020] 4. By setting the circular plate, the contact area with the hydraulic cylinder is increased and stress concentration is reduced.
