Abstract

The invention relates to electrolytic manganese equipment, particularly an anode for electrolytic manganese. In order to overcome the problems of short service time and poor corrosion resistance in the traditional platy anode at present, the invention provides a novel anode for electrolytic manganese. The anode for electrolytic manganese comprises a striped conducting rod and a columnar anode column connected to the conducting rod, wherein one end of the anode column connected with the conducting rod is also provided with a protective sleeve, and the protective sleeve is sheathed on the anode column. The anode initially uses the columnar-structure anode column instead of the traditional porous anode plate and arranges the protective sleeve on the anode column, thereby enhancing the production efficiency of the electrolytic manganese. The anode thoroughly solves the problems of corrosion and plate breaking, and the service life of the electrolytic manganese lead alloy anode plate used in a high-fluorine chlorine electrolyte is prolonged from 2-5 months to 20-26 months.

Description

technical field [0001] The invention relates to electrolytic manganese equipment, in particular to an anode for electrolytic manganese. Background technique [0002] At present, in the traditional electrolytic manganese production, the anodes for electrolytic manganese are composed of conductive rods and lead alloy anode plates with holes. The perforated anode plate is first cast into a plate and then rolled into a thin plate and punched. The thickness of this anode plate is generally 8 mm, which is relatively thin and has a short service life. The service life of the traditional plate-shaped anode is 18-24 1. Large surface area and low current density (generally 600-700 amps / square meter), anode slag is easily generated during electrolysis of manganese, which wastes resources, affects electrolysis efficiency and manganese production, and increases the work of cleaning anode slag quantity. In addition, with the depletion of manganese ore resources in the domestic interior,...
