Description

technical field [0001] The invention relates to a roller kiln, in particular to a microwave roller kiln in which microwave heating is used to replace traditional resistance heating, gas heating and fuel oil heating. technical background [0002] Roller kiln is a large-scale kiln with continuous feeding and continuous discharging. It has high production efficiency and is widely used in drying and sintering of ceramics, metallurgy, battery materials and other industries. The current heating methods are resistance heating, gas heating and fuel heating. The structure of the traditional roller kiln is: including resistance heating, gas heating or fuel oil heating, heating section furnace body, heat preservation section furnace body, cooling section furnace body, dehumidification exhaust system, cooling exhaust system, temperature measurement and control system , Insulation system and transmission system, using resistance heating, gas heating or fuel heating to form the heating s...

AI Technical Summary

Problems solved by technology

The structure of the traditional roller kiln is: the furnace body of the heating section, the furnace body of the heat preservation section, the furnace body of the cooling section, the dehumidification and exhaust system, the cooling and exhaust system, and the temperature measurement and control system, which are composed of resistance heating, gas heating or fuel oil heating. , Insulation system and transmission system, using resistance heating, gas heating or fuel heating to form the heating section furnace body and heat preservation section furnace body, resistance heating, gas heating or fuel heating to heat the material, the sintering temperature is generally relatively high, and the reaction speed is slow , the quality of the material after sintering is low; the drying heating temperature for the material is high, and the drying speed is slow
