Power supply device for electrolytic manganese

Abstract

The invention provides a power supply unit for manganese electrolysis. According to the power supply unit, a 380V three-phase power supply is taken as an input end, current of the electrolysis is converted into single-phase half-wave current by a rectifying circuit module, a low-frequency filter circuit converts the single-phase half-wave current into low-frequency direct current which is converted into high-frequency alternating current with a preset frequency by an inverter circuit module, then a high-frequency transformer converts the high-frequency alternating current into low-voltage high alternating current which is converted into high-frequency rectangular wave pulse current by a high-frequency rectifying circuit module, and finally, a high-frequency filter circuit module converts the high-frequency rectangular wave pulse current into high-frequency square wave pulse current or high-frequency direct current bias current which is output. By the setting of the frequency of the inverter circuit module and the duty ratio of the high-frequency rectifying circuit module, the power supply unit provided by the invention can output the high-frequency square wave pulse current with the frequency being 10000Hz, the pulse peak height being 4.5V, the maximum current being 30000A, and the duty ratio being 90%.

Description

technical field [0001] The invention belongs to the technical field of electrolytic manganese, in particular to a power supply device for electrolytic manganese. Background technique [0002] There are mainly two ways to extract manganese metal: thermal method and electrolytic method. Among them, the thermal method is also called fire method, and the purity of manganese metal obtained by this method is not more than 95% to 98%; the electrolytic method is also called wet method. The purity of manganese metal can reach more than 99.7-99.9%. Therefore, the electrolytic method has become the main production method for the preparation of metal manganese, and electrolytic manganese is widely used in iron and steel smelting, nonferrous metallurgy, electronic technology, chemical industry, environmental protection, food hygiene, welding rod industry, etc. due to its high purity and low impurities. In aerospace industry and other fields, electrolytic manganese and manganese alloys a...
