Description

A rapidly heating oxygen-enriched side-blown furnace Technical Field

[0001] This utility model relates to the field of oxygen-enriched side-blown furnace technology, and in particular to an oxygen-enriched side-blown furnace that can rapidly heat up. Background Technology

[0002] The oxygen-enriched side-blown furnace, capable of rapid heating, utilizes an oxygen-enriched environment to accelerate combustion reactions and significantly increase the heating rate. In smelting, it can quickly bring the furnace to a suitable high temperature, accelerating the ore smelting process, improving metal extraction efficiency, reducing energy consumption, and offering flexible operation, making it of great significance for improving smelting capacity and quality.

[0003] However, during operation, existing oxygen-enriched side-blown furnaces suffer from severe oxygen unevenness due to limitations in internal structural design or gas supply systems. Some areas have excess oxygen, resulting in waste, while others are oxygen-deficient, preventing the combustion reaction from proceeding fully. This directly leads to low combustion efficiency and ineffective energy release, resulting in extremely slow temperature rise inside the furnace, which greatly affects production progress and energy utilization efficiency.

[0004] Therefore, this application provides an oxygen-enriched side-blown furnace with rapid heating to meet the requirements. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an oxygen-enriched side-blown furnace capable of rapid heating.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an oxygen-enriched side-blown furnace capable of rapid heating, comprising:

[0007] Side-blown furnace body;

[0008] An oxygenation assembly is placed on top of the side-blown furnace body. The oxygenation assembly includes a guide tube fixed to the top of the side-blown furnace body, a first connecting ring is provided between the guide tubes, and an oxygenation tube is fixed to the top of the guide tube.

[0009] A guide assembly is placed at the bottom of the oxygenation assembly. The guide assembly includes a second connecting ring fixed to the bottom of the oxygenation assembly. An annular plate is fixed to the bottom of the second connecting ring. A rotating shaft is provided in the middle of the second connecting ring. A blade is fixed in the middle of the rotating shaft. Third connecting rings are sleeved on both sides of the rotating shaft away from the blade. An arc-shaped piece is fixed between the third connecting rings.

[0010] Furthermore, an arc-shaped plate is fixed to the bottom of the second connecting ring, and an outward expansion plate is fixed to the outer side of the bottom of the arc-shaped plate.

[0011] The beneficial effects of adopting the above-mentioned further scheme are: the arc-shaped plate at the bottom of the second connecting ring guides the oxygen to flow downward, and the outer expansion plate on the bottom side further diffuses the oxygen, so that the oxygen covers a wider range and is distributed more evenly in the furnace.

[0012] Furthermore, guide holes are uniformly provided on the arc-shaped plate.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the guide holes are evenly distributed on the arc plate, and the oxygen is diverted through the holes, which further optimizes the dispersion effect of oxygen in the furnace.

[0014] Furthermore, a feed inlet is fixed on the top side of the side-blown furnace body away from the oxygen filling component.

[0015] The beneficial effects of adopting the above-mentioned further solution are: the feed port at the top of the side-blown furnace body is used for feeding materials, which is easy to operate and ensures a continuous supply of materials in the furnace.

[0016] Furthermore, the interior of the side-blown furnace body is uniformly provided with arc-shaped slots.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the arc-shaped slot inside the side-blown furnace body increases the contact area between the material and the airflow inside the furnace, thereby improving the heat exchange efficiency.

[0018] Furthermore, a filter plate is fixed inside the side-blown furnace body.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the filter plate inside the side-blown furnace body filters impurities during material reaction, ensuring a clean reaction environment inside the furnace.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. The oxygen filling component is set on the top of the side-blown furnace body and is used to deliver oxygen-enriched air into the furnace to promote combustion and heating. The oxygen filling pipe is fixed on the top of the guide pipe and is the input channel for oxygen-enriched air. The guide pipe is responsible for guiding the oxygen input from the oxygen filling pipe into the furnace. The first connecting ring between them serves to reinforce the guide pipe, ensuring that oxygen enters the furnace body stably and efficiently, and improving the heating rate.

[0022] 2. The second connecting ring connects the guide assembly and the oxygen filling assembly, ensuring structural stability. Its bottom annular plate regulates the oxygen flow direction, allowing oxygen to enter the furnace in an orderly manner. The rotating shaft is located in the middle of the second connecting ring. When it is running, it drives the central blades to rotate, acting like a propeller to fully deliver oxygen into the tank, ensuring uniform oxygen distribution. The rotating shaft is fitted with third connecting rings on both sides, with arc-shaped plates fixed in between. When the airflow is strengthened, the arc-shaped plates cause turbulence, promoting full mixing of oxygen and materials, improving combustion efficiency. At the same time, due to the unique arc-shaped design, airflow noise is reduced, allowing the equipment to operate quietly and stably. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] As shown in Figures 1-3, this utility model provides a technical solution: an oxygen-enriched side-blown furnace capable of rapid heating, comprising: a side-blown furnace body 1;

[0035] Oxygen filling assembly 5 is located on the top of the side-blown furnace body 1. The oxygen filling assembly 5 includes a guide pipe 52 fixed on the top of the side-blown furnace body 1, a first connecting ring 53 between the guide pipes 52, and an oxygen filling pipe 51 fixed on the top of the guide pipes 52. The oxygen filling assembly 5 is located on the top of the side-blown furnace body 1 and is used to deliver oxygen-enriched air into the furnace to promote combustion and heating. The oxygen filling pipe 51 is fixed on the top of the guide pipe 52 and is the input channel for oxygen-enriched air. The guide pipe 52 is responsible for guiding the oxygen input from the oxygen filling pipe 51 into the furnace. The first connecting ring 53 between them serves to reinforce the guide pipe 52, ensuring that oxygen enters the furnace body stably and efficiently, and improving the heating rate.

[0036] The guide assembly 7 is located at the bottom of the oxygenation assembly 5. The guide assembly 7 includes a second connecting ring 71 fixed to the bottom of the oxygenation assembly 5. An annular plate 72 is fixed to the bottom of the second connecting ring 71. A rotating shaft 75 is located in the middle of the second connecting ring 71, and a blade 76 is fixed to the middle of the rotating shaft 75. Third connecting rings 73 are sleeved on both sides of the rotating shaft 75 away from the blade 76. Arc-shaped pieces 74 are fixed between the third connecting rings 73. The second connecting ring 71 connects the guide assembly 7 and the oxygenation assembly 5, ensuring the connection... The structure is stable, and its bottom annular plate 72 regulates the oxygen flow, allowing oxygen to enter the furnace in an orderly manner. The rotating shaft 75 is located in the middle of the second connecting ring 71. When it is running, it drives the central blade 76 to rotate, which, like a propeller, fully delivers oxygen into the tank, ensuring uniform oxygen distribution. The rotating shaft 75 is fitted with third connecting rings 73 on both sides, with arc-shaped plates 74 fixed in between. When the air force is increased, the arc-shaped plates 74 turbulent the airflow, promoting full mixing of oxygen and materials, improving combustion efficiency. At the same time, due to the unique arc design, airflow noise is reduced, making the equipment operate quietly and stably.

[0037] Furthermore, as shown in Figures 1-3: an arc-shaped plate 77 is fixed to the bottom of the second connecting ring 71, and an outer expansion plate 78 is fixed to the outer side of the bottom of the arc-shaped plate 77. The arc-shaped plate 77 at the bottom of the second connecting ring 71 guides the oxygen to flow downward, and the outer expansion plate 78 on the outer side of its bottom further diffuses the oxygen, so that the oxygen covers a wider range and is distributed more evenly in the furnace.

[0038] Furthermore, as shown in Figures 1-3: In this design, guide holes 79 are evenly distributed on the arc plate 77, and oxygen is diverted through the holes, further optimizing the dispersion effect of oxygen in the furnace.

[0039] Working Principle: As shown in Figures 1-4, the oxygen filling component 5 is installed on the top of the side-blown furnace body 1. The oxygen filling pipe 51 is fixed to the top of the guide pipe 52, becoming the input channel for oxygen-enriched air. External oxygen-enriched air enters through this channel, and the guide pipe 52 guides it into the furnace. The first connecting ring 53 reinforces the guide pipe 52, ensuring stable and efficient oxygen input and accelerating heating. The guide component 7 is connected to the oxygen filling component 5 through the second connecting ring 71, ensuring structural stability. The annular plate 72 regulates the oxygen flow, allowing oxygen to enter the furnace in an orderly manner. The rotating shaft 75 is located in the middle of the second connecting ring 71. When the rotating shaft 75 is rotated by an external power source, it drives the blades 76 to rotate, fully delivering oxygen into the tank and achieving uniform distribution. The rotating shaft 75 is fitted with third connecting rings 73 on both sides. The fixed arc-shaped blades 74 enhance the airflow. Turbulence promotes thorough mixing of oxygen and materials, improving combustion efficiency. The unique arc design also reduces airflow noise. The arc plate 77 at the bottom of the second connecting ring 71 guides oxygen downwards, and the outer expansion plate 78 further diffuses oxygen, expanding the coverage area. The guide hole 79 on the arc plate 77 diverts oxygen and optimizes the dispersion effect. The feed port 4 at the top of the side-blown furnace body 1 facilitates the operator to add materials, ensuring a continuous supply of materials. The internal arc groove 8 increases the contact area between materials and airflow, improving heat exchange efficiency. The filter plate 6 filters impurities during material reaction, maintaining a clean environment inside the furnace. The support leg 2 is located at the bottom of the side-blown furnace body 1, supporting the entire furnace body and ensuring stable operation. The bottom discharge port 3, located away from the support leg 2, is used to discharge the finished product after melting, completing the entire production process.
