Heating furnace for conducting microwave treatment on ore and application method of heating furnace

Abstract

The invention relates to a heating furnace for conducting microwave treatment on ore and an application method of the heating furnace. The heating furnace comprises a microwave treatment cavity 7. A feeding port 3 is fixedly connected with the top of the microwave treatment cavity 7. An exhaust fan 2 is fixedly connected with the top of the microwave treatment cavity 7 through a pipeline. A material distributor 4 is fixedly connected with the microwave treatment cavity 7 through a cross rod. The top end of the material distributor 4 coincides with the center line of an outlet of the feeding port 3. Microwave generators 5 are located on the periphery of the microwave treatment cavity 7. A gas pressure sensor 6 is located in the microwave treatment cavity 7 and fixedly connected with the microwave treatment cavity 7. An inlet of a discharging end 9 is fixedly connected with the bottom of the microwave treatment cavity 7. A discharging control device 8 is arranged at the middle portion of the discharging end 9. A cooling pond 10 is located at the lower portion of the discharging end 9. An air blower 16 is located at the bottom of the microwave treatment cavity 7 and fixedly connected with the microwave treatment cavity 7 through a pipeline. An air flow controller 18 is electrically connected with the exhaust fan 2 and the air blower 16. The heating furnace is simple in structure and safe and convenient to use; and by means of the method, high-temperature and rapid treatment of the ore can be achieved, the mineral can be efficiently dissociated, and the requirement for continuous operation is met.

Description

technical field [0001] The invention belongs to the technical field of microwave treatment of ores, and in particular relates to a heating furnace for microwave treatment of ores and a use method thereof. Background technique [0002] At present, traditional ore heating equipment includes electric furnaces, rotary kilns, and shaft furnaces. Traditional heating equipment generally uses electricity, coal or natural gas to heat. These methods have low heating efficiency, slow temperature rise, serious pollution, high energy consumption, and a lot of waste. Disadvantages such as poor energy or poor processing effect on ore. [0003] As a new heating method, microwave has been widely used in daily life. During the heating of ore by microwave, the ore absorbs microwave and generates high temperature, which starts heating from the inside. Microwave heating is used to heat the ore, and the temperature rise rate of the ore is fast, which can quickly rise to the processing temperatu...

AI Technical Summary

Problems solved by technology

Although this device can make the ore heat up rapidly in the furnace, it cannot effectively disperse the ore in the microwave field, and cannot effectively process the material.
