Closed steel-frame electrolytic tank

The utility model relates to an electrolyzer, in particular to the sealed steel frame electrolyzer which is used for the electrolysis of the nonferrous metal solution. The utility model is designed to provide a sealed steel frame electrolyzer that has a simple structure, low cost, being corrosion resistant, no liner container being drawn broken and with the separated metal from the cathode easy to be peeled off. The utility model overcomes the defects of the current electrolyzer that have high manufacturing cost, tend to leak or the liner is easy to be drawn broken etc. The utility model is composed of a steel frame and a liner container. The liner container is positioned inside of the steel frame. The utility model is characterized in that the top of the liner container has three flanging edges and a flat edge. The liquid inlet edge is a slope. The liquid outlet edge is a rectangular overflow port. Between the liquid inlet edge and the liquid outlet edge is a parallel stop plate. The outside of the steel frame is the anticorrosive coating 8. The utility model is mainly used to the electrolysis of the nonferrous metal solution.
