Description

Technical Field

[0001] The utility model relates to the technical field of environment-friendly ore furnaces, in particular to an environment-friendly submerged arc furnace. Background Art

[0002] An environment-friendly submerged arc furnace is an industrial furnace specially used for smelting metals and other minerals. Compared with traditional submerged arc furnaces, it pays more attention to environmental protection in design and operation. Environment-friendly submerged arc furnaces usually adopt advanced energy utilization technologies to improve energy conversion efficiency, reduce energy waste, thereby reducing the demand for fuel and corresponding emissions.

[0003] After retrieval, an environment-friendly submerged arc furnace for producing silicon-zirconium alloy with the publication number CN211425083U relates to the technical field of submerged arc furnace equipment. One side of the submerged arc furnace shell is embedded with a feed port, and above the feed port on the other side of the submerged arc furnace shell is embedded with a first air outlet. A sealing component is screwed in the first air outlet. On the side of the first air outlet away from the submerged arc furnace shell, an environment-friendly box body is fixedly installed. The upper surface of the environment-friendly box body is embedded with a second air outlet, and an environment-friendly component is fixedly installed inside the environment-friendly box body. The environment-friendly submerged arc furnace for producing silicon-zirconium alloy is provided with a sealing component and an environment-friendly component. Workers can drive the compression spring fixedly connected to the adjusting screw rod to rotate by rotating the adjusting screw rod, press and close the two baffles, so as to seal the inside of the first air outlet and prevent the generated flue gas from leaking. The timing of the flue gas discharged from the submerged arc furnace shell can be controlled as needed.

[0004] Based on the above patent, by rotating the adjusting screw rod to drive the compression spring fixedly connected to the adjusting screw rod to rotate, the two baffles are pressed and closed, so that the first air outlet is sealed to prevent the generated flue gas from leaking. The timing of the flue gas discharged from the submerged arc furnace shell can be controlled as needed. The limiting blocks fixedly installed on both sides of the compression spring make the compression spring work more stably. The adjusting screw rod is a component made of tin bronze, which has good mechanical properties, anti-friction properties and corrosion resistance. The environment-friendly submerged arc furnace for producing silicon-zirconium alloy is provided with an environment-friendly component. After the reaction ends, the adjusting screw rod is unscrewed to allow the flue gas to enter the environment-friendly pipeline fixedly installed with the first air outlet through the first air outlet. Through the filtering effect of the filter element at the bottom of the environment-friendly pipeline, the water vapor and soot in the flue gas carrying a large amount of heat are filtered, and the flue gas is secondarily filtered through the filter cylinder to make the flue gas cleaner. However, when this patent is used, the airtightness is not good when the submerged arc furnace shell is connected to the furnace cover. Poor airtightness will cause various harmful gases generated in the furnace to leak into the working environment, endangering the health of operators and polluting the environment. In addition, poor airtightness leads to heat loss, increasing the energy consumption for heating and maintaining a high-temperature environment, thereby increasing the operating cost of the furnace and reducing the energy efficiency.

Detailed Embodiment

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Referring to Figures 1-5 , an embodiment provided by the utility model: an environment-friendly submerged arc furnace, which includes a submerged arc furnace shell 1. The left end of the outer wall of the submerged arc furnace shell 1 is fixedly connected with a feed pipe 2 and penetrates through it. The right end of the outer wall of the submerged arc furnace shell 1 is fixedly connected with a connecting pipe 4 and penetrates through it. The right end of the connecting pipe 4 is fixedly connected with a filter chamber 5 and penetrates through it. The rear side of the top end of the filter chamber 5 is rotatably connected with a connecting cover 6. Both the left and right sides of the front end of the connecting cover 6 are fixedly connected with clamping blocks 8. The left and right ends of the front outer wall of the filter chamber 5 are rotatably connected with safety catches 7. The inner wall of the filter chamber 5 is connected with a filter net 9 through a filtering component. The top end of the submerged arc furnace shell 1 is detachably connected with a furnace cover 3. The top end of the submerged arc furnace shell 1 is connected with an airbag ring 10 through a sealing component. The top end of the safety catch 7 is detachably connected to the inner wall of the clamping block 8. The top end of the airbag ring 10 is in close contact with the inner wall of the bottom end of the furnace cover 3. The combustion materials are put into the submerged arc furnace shell 1 through the feed pipe 2, so that the materials in the submerged arc furnace shell 1 burn. The air generated by the combustion is transmitted to the filter chamber 5 through the connecting pipe 4, and the harmful substances generated by the combustion of the materials are filtered by the filter net 9, thereby preventing the harmful substances from entering the air.

[0027] Specifically, the left end of the outer wall of the airbag ring 10 is fixedly connected with an exhaust pipe 11 and penetrates through it. The right end of the outer wall of the airbag ring 10 is fixedly connected with an air inlet pipe 12. The inner wall of the air inlet pipe 12 is fixedly connected with a fixed pipe 13. The rear end of the inner wall of the fixed pipe 13 is slidably connected with a one-way pipe 15 through a return spring 14. The bottom end of the return spring 14 is fixedly connected to the top end of the one-way pipe 15. The top end of the return spring 14 is fixedly connected to the top end inner wall of the fixed pipe 13. Air is infused into the air inlet pipe 12, so that the air pressure conveys the air from the one-way pipe 15, and the air is infused into the airbag ring 10 through the exhaust pipe 11, thereby causing the airbag ring 10 to expand due to the air pressure. The expansion of the airbag ring 10 seals between the submerged arc furnace shell 1 and the furnace cover 3, thereby improving the sealing effect of the device. And the good sealing effect can effectively prevent heat loss, improve energy utilization efficiency, reduce fuel consumption, thereby reducing operating costs and carbon footprint, and reducing the leakage of harmful gases, thereby reducing air pollution, meeting environmental protection regulations and standards.

[0028] Specifically, docking pipes 16 are fixedly connected to the four sides of the bottom end of the filter net 9. Docking blocks 20 are fixedly connected to the four sides of the inner wall bottom end of the docking pipes 16. Fixed blocks 17 are fixedly connected to the four sides of the inner wall bottom end of the filter chamber 5. Outer expansion blocks 19 are rotatably connected to the front and rear sides of the top ends of the fixed blocks 17 through torsion springs 18. The right ends of the torsion springs 18 are fixedly connected to the right ends of the inner walls of the fixed blocks 17, and the left ends of the torsion springs 18 are fixedly connected to the left ends of the inner walls of the outer expansion blocks 19. The opposite ends of the outer expansion blocks 19 are detachably connected to the front and rear ends of the inner wall of the docking pipes 16 respectively, and are used for filtering harmful gases. After replacing the filter net 9, the filter net 9 is docked to the fixed block 17, so that the docking pipe 16 presses the docking block 20, and the docking block 20 presses the outer expansion block 19 to expand to both sides, so that the outer expansion block 19 is stuck to the docking pipe 16 on both sides, and the docking block 20 falls off from the outer expansion block 19, and the torsion spring 18 makes the outer expansion block 19 relatively close through torsion, so as to fall off at the docking pipe 16, thus facilitating the replacement of the filter net 9. The design that is convenient for replacement enables the operator to replace the filter net in time, ensures that the filter net always operates in the best state, effectively captures particulate matter and pollutants, thus maintaining high filtration performance and extending the overall service life of the equipment.

[0029] Working principle: First, the combustible material is put into the submerged arc furnace shell 1 through the feed pipe 2, so that the material in the submerged arc furnace shell 1 burns. The air generated by the combustion is transmitted to the filter chamber 5 through the connecting pipe 4, and the harmful substances generated by the combustion of the material are filtered by the filter net 9, so as to prevent the harmful substances from entering the air. Then, air is infused into the intake pipe 12, so that the air pressure conveys the air from the one-way pipe 15, and the air is infused into the airbag ring 10 through the exhaust pipe 11. Thus, the airbag ring 10 expands due to the air pressure, and the expansion of the airbag ring 10 seals between the submerged arc furnace shell 1 and the furnace cover 3, thereby improving the sealing effect of the device. And the good sealing effect can effectively prevent heat loss, improve energy utilization efficiency, reduce fuel consumption, thereby reducing the operating cost and carbon footprint, and reducing the leakage of harmful gases, thereby reducing air pollution, meeting environmental protection regulations and standards. And for filtering harmful gases, after replacing the filter net 9, the filter net 9 is docked to the fixed block 17, so that the docking pipe 16 presses the docking block 20, and the docking block 20 presses the outer expansion block 19 to expand to both sides, so that the outer expansion block 19 is stuck to the docking pipe 16 on both sides, and the docking block 20 falls off from the outer expansion block 19, and the torsion spring 18 makes the outer expansion block 19 relatively close through torsion, so as to fall off at the docking pipe 16, thus facilitating the replacement of the filter net 9. The design that is convenient for replacement enables the operator to replace the filter net in time, ensures that the filter net always operates in the best state, effectively captures particulate matter and pollutants, thus maintaining high filtration performance and extending the overall service life of the equipment.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
