In addition, the ion membrane in the prior art electrolyzers requires a relatively cumbersome method to be installed with the electrolyzer, which causes certain difficulties for the operator in actual operation, and is time-consuming and labor-intensive. To achieve the above-mentioned purpose, the present invention provides the following technical solution: an ion-exchange membrane electrolyzer that facilitates electrolyte replacement, comprising a support frame, a liquid extraction mechanism is horizontally penetrated on one side of the support frame, a liquid inlet end of the liquid extraction mechanism is plugged into the left and right sides of the bottom wall of the cell body, a top cover is engaged at the top opening of the cell body, a fixing mechanism is threadedly connected to the bottom of the top cover, an ion membrane is clamped inside the fixing mechanism, a cathode plate is engaged on one side of the top wall of the top cover, an anode plate is engaged on the other side of the top wall of the top cover, and a liquid inlet pipe is engaged on the side of the top of the cell body near the cathode plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, the liquid pump can quickly extract the old electrolyte from the inside of the tank body through the combination of the liquid inlet pipe and the liquid extraction pipe, thereby making room for the injection of new electrolyte.

At the same time, the quick discharge valve can accurately control the inflow of new electrolyte to avoid electrolyte waste caused by overfilling.

[0014] In the present invention, the operator can first insert the upper and lower ends of the ion membrane into the corresponding positions of the abutment frame respectively. At this time, the left and right sides of the ion membrane will push the sealing clamps in contact therewith, so that the compression spring parts provided between the sealing clamps and the inner wall of the abutment frame are squeezed synchronously, thereby adjusting the spacing between the sealing clamps on the left and right sides so that they can just accommodate the ion membrane to pass through. At the same time, the compression spring parts will use their rebound properties to push the sealing clamps in the opposite direction to clamp the ion membrane. During this period, through the design of the compression spring parts, the fixing mechanism can adapt to ion membranes of different thicknesses, thereby providing a certain adjustment range, and the sealing clamps can fit tightly to the surface of the ion membrane and form a good sealing effect, which can effectively prevent the electrolyte from leaking from the gap between the two, thereby ensuring the sealing of the ion membrane in the tank body, while also maintaining the stability of the pressure and chemical environment inside the tank body. At the same time, the ion membrane is clamped between the sealing clamps and the abutment frame, which can help maintain the position of the ion membrane stable during the electrolysis process, preventing it from moving or deforming, thereby affecting the electrolysis reaction.
