A heating furnace for ore microwave treatment and its application method

Abstract

The invention relates to a heating furnace for microwave treatment of ore and a using method thereof. The heating furnace includes: a microwave processing cavity 7; the feed port 3 is fixedly connected to the top of the microwave processing cavity 7; the exhaust fan 2 is fixedly connected to the top of the microwave processing cavity 7 through a pipeline; the distributor 4 is connected to the microwave processing cavity through a cross bar. The cavity 7 is fixedly connected, and the top of the distributor 4 coincides with the center line of the outlet of the feed port 3; the microwave generator 5 is located around the microwave processing cavity 7; the gas pressure sensor 6 is located inside the microwave processing cavity 7 and is fixedly connected with the microwave processing cavity 7; The inlet of the material end 9 is fixedly connected with the bottom of the microwave processing chamber 7, and a discharge control device 8 is arranged in the middle of the discharge end 9; the cooling pool 10 is located at the bottom of the discharge end 9; the blower 16 is located at the bottom of the microwave processing chamber 7, and is connected to the 7 is fixedly connected through pipelines; the air volume controller 18 is electrically connected with the exhaust fan 2 and the blower 16. The device has a simple structure and is safe and convenient to use; the method can realize high-temperature rapid processing of ores, efficiently dissociate minerals, and meet continuous operation requirements.

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.
