A smart combustion furnace Technical Field

[0001] This invention relates to the field of combustion furnace equipment technology, specifically to an intelligent combustion furnace. Background Technology

[0002] An electric arc furnace, also known as a carbon-sulfur combustion furnace or simply an electric arc furnace, is a device that uses a high-voltage, high-frequency oscillating circuit to generate a large instantaneous current to ignite the sample. The sample then rapidly combusts under oxygen-rich conditions, producing a mixed gas. This gas mixture is then analyzed quantitatively and quickly using chemical analysis procedures to determine the carbon and sulfur content in the sample. The electric arc furnace is one of the most common pieces of equipment in modern steelmaking.

[0003] In existing combustion furnaces, the refining materials are typically poured directly into the furnace during refining, causing them to accumulate inside. Furthermore, poor ventilation within the furnace often leads to incomplete combustion, impacting thermal efficiency. Additionally, the lack of a cleaning mechanism for the furnace walls results in a buildup of residual fuel, reducing the furnace's lifespan. To address these issues, the inventors propose an intelligent combustion furnace. Summary of the Invention

[0022] A blower 23 is provided inside the elevator 19 on the side near the outer casing 8, and a blower 29 is provided at the bottom of the elevator 19 and near the medium particle storage bin 20.

[0023] By adopting the above technical solution, a blower 23 is installed near one side inside the lifter 19 to facilitate the conveying of raw materials through the lifter 19 to the inlet 17.

[0024] A humidity sensor 27 is provided on the side of the insulation barrel 11 near the drying cylinder 31. A flue 10 is provided on the side of the insulation barrel 11 near the humidity sensor 27. Two temperature sensors 30 are provided on the outer ring of the drying cylinder 31 near the outer shell 8.

[0025] By adopting the above technical solution, a flue 10 is set on the side of the insulated barrel 11 near the top in order to discharge its flue gas.

[0026] A rotatable brush 12 is provided above the rotating tray 6, and the rotatable brush 12 is in contact with the inner wall of the insulated bucket 11.

[0027] By adopting the above technical solution, a rotatable brush 12 is installed inside the insulated bucket 11, thereby achieving the effect of cleaning the inner wall.

[0029] By adopting the above technical solution, a motor is installed at the bottom of the outer casing 8, and the motor is run, thereby causing the fixedly connected rotatable brush 12 to rotate.

[0036] Working principle: First, the raw material is poured into the feed inlet 17, and then transported to the feed inlet 17 by the vibrating screener 15. Particles smaller than 6mm will enter the conveyor belt 13 from the fine particle inlet 18, and particles smaller than 10mm will enter the medium particle storage bin 20 from the medium particle inlet 16. Other particles will enter the coarse particle storage bin from the coarse particle inlet 14. After being crushed by the medium particle crusher 21 and the coarse particle crusher 22 respectively, they will enter the transport pipeline. The blower 1 23 provides power so that the particles can enter the lifter 19. The blower 2 29 provides air power to transport them to the feed inlet 17 for screening again, thereby achieving the effect of repeated screening of raw materials. This solves the problem of incomplete combustion of refining materials due to poor ventilation in the furnace.

[0037] After entering the conveyor belt 13, fine particles are transported to the rotating tray 6 in the combustion furnace. The rotating tray 6 ensures uniform material distribution through rotation, allowing for more complete combustion. The temperature sensor 7 measures the furnace temperature, and the size of the air intake fan 4 is adjusted based on the measured temperature to control the amount of oxygen entering the combustion furnace and adjust the combustion rate. The air guide cylinder 24 guides air and discharges ash. When the air guiding function is activated, the ash discharge port 26 is closed, and the air intake fan 4 is activated. If combustion is still incomplete after the air intake fan 4 is activated, the oxygen cylinder 28 is opened to introduce appropriate oxygen. When the ash discharge mode is activated, the air intake fan 4 is closed, and the ash discharge port 26 is opened. Under the up-and-down vibration of the vibration device 5, the ash after combustion can be discharged. The rotatable brush 12 can clean the ash on the inner wall of the insulated barrel 11 combustion furnace by rotation, improving the service life of the insulated barrel 11 combustion furnace and thus solving the problem of the lack of a structure for cleaning the inner wall of the combustion furnace, which easily leads to a large amount of residual fuel adhering to the inner wall of the combustion furnace.
