Electrolytic cell

Abstract

An electrolytic cell comprises a steel frame and a metal shell disposed outside the steel frame, wherein grooves are disposed in left-right symmetry on the steel frame; inside the steel frame, a lead bladder is mounted; ridges matched with the grooves are disposed on the lead bladder; the ridges are inserted in the grooves, which facilitates the mounting of the lead bladder inside the steel frame; a groove is disposed symmetrically on the left and right side surfaces of the steel frame; and two grooves are disposed symmetrically on the upper and lower side surfaces of the steel frame. By substituting the lead bladder for the original plastic bladder, the bulging of bladder due to thermal expansion is prevented, and a better corrosion protection effect is achieved; the detachable arrangement of the lead bladder in the steel frame facilitates maintenance in case that the lead bladder is damaged, so that the electrolytic cell is prevented from being rejected due to the damage of lead bladder, and the production cost is reduced.

Description

technical field [0001] The invention relates to an electrolytic cell, in particular to an electrolytic cell with good anti-corrosion effect and easy maintenance, and belongs to the technical field of electrolytic equipment. Background technique [0002] Today's electrolyzers use all-plastic integrally formed liners placed in steel frames to prevent electrolyte corrosion. This structure of electrolyzers has the following disadvantages: First, due to large temperature changes, plastics will expand with heat and contract with cold. , resulting in bubbling of the liner, leading to the scrapping of the electrolyzer; second, the all-plastic integrally formed liner is welded in the steel frame, which is not easy to disassemble and assemble. When the all-plastic integrally formed liner is damaged, maintenance is troublesome, which may lead to the scrapping of the entire electrolyzer. Increased production costs. Contents of the invention [0003] In view of the above-mentioned t...
