Description

technical field [0001] The invention relates to a microwave drying device for welding electrodes, which belongs to the technical field of microwave heating devices. Background technique [0002] The welding rod drying device is widely used in national key construction units such as machinery, electric power, metallurgy, chemical industry, petroleum, and urban construction. It is a necessary drying equipment for welding projects. How to make full use of heat during drying, At the same time, reducing the waste rate is a problem that needs to be studied all the time. At present, most welding rod drying devices use far-infrared resistors or natural gas as heat sources, use convection, conduction and radiation as heat transfer methods, and use air or furnace body as the medium to transmit heat. The heat is transferred from the outer layer of the welding rod coating to Transfer inside to dry the electrode. However, due to the defects of the heating principle of the above-mention...
