Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electrodialysis, specifically to a kind of feed adjustable electrodialysis device. BACKGROUND

[0002] The method for separating different solute particles using the selective permeability of semi-permeable membrane is called dialysis. When dialysis is carried out under the action of an electric field, the phenomenon that charged solute particles in a solution migrate through the membrane is called electrodialysis. Electrodialysis is widely used in chemical, light industry, metallurgy, papermaking and pharmaceutical industries for purifying and separating substances.

[0003] According to the electrodialysis experimental device (announcement number: CN221471451U) disclosed, the above-mentioned application is provided with a water storage tank outside the electrodialysis shell, which can store the solution before injection. The water storage tank can be used in combination with the metering pump and the water suction pipe to extract the solution in the water storage tank through the water suction pipe. The water storage tank can be used in combination with the water delivery pipe, the communication pipe and the water injection pipe to inject the solution into the electrodialysis shell. Then, the electrodialysis shell can be used to realize the purposes of desalination, concentration, refining and purification of the solution. Furthermore, the device has a structure for automatically injecting a certain amount of solution, which can improve the injection speed of the solution during the electrodialysis experiment.

[0004] However, the above-mentioned device cannot close the opening of the water delivery pipe after water injection during actual use. When the liquid level in the electrodialysis shell is higher than the inlet of the water delivery pipe, the liquid in the electrodialysis shell may flow back to the water storage tank after the water delivery pipe stops delivering water, which can contaminate the water in the water storage tank. Therefore, the present application provides a feed adjustable electrodialysis device. UTILITY MODEL CONTENTS
