A device for microwave-assisted activation of manganese dioxide

technical field

The utility model relates to a device for activating manganese dioxide assisted by microwaves, which belongs to the field of metallurgical equipment design.

Background technique

Manganese dioxide is the main positive electrode material of dry batteries, and its quality plays a decisive role in the performance of zinc-manganese dry batteries. Activated manganese dioxide is to make natural manganese ore or manganese salt through roasting reduction, acid activation and other steps, and use disproportionation reaction to produce artificial manganese dioxide. Microwave technology has been widely used in the field of metallurgy in recent years. Using its unique selective heating, from the inside to the outside, the non-contact, clean and fast heating method has been used to assist the drying, leaching, reduction, grinding, etc. of minerals. Based on the existing equipment, the device of the utility model uses microwaves as a heating source to roast and activate manganese dioxide minerals. Manganese dioxide ore can achieve rapid temperature rise under microwave heating, reaching the temperature at which manganese dioxide decomposes. At the same time, microwave heating can increase the surface porosity of minerals, which is beneficial to the next step of acidification.
