[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0029] This utility model provides a ladle baking device that solves the technical problem that insufficient oxygen supply during ladle baking easily leads to reduced baking efficiency. The ladle baking device includes a baking tray 1, a gas supply pipe 2, an air duct 3, and an air guide plate 4, wherein:

[0030] The inner wall of the baking tray 1 is provided with a baking groove 11. When baking the molten iron ladle, the baking tray 1 is placed above the molten iron ladle to heat it. The baking tray 1 is used to prevent heat from spreading away from the molten iron ladle, so that the heat can be better radiated towards the molten iron ladle.

[0031] One end of the gas supply pipe 2 is connected to the gas source, and the other end is connected to the baking tank 11. The gas supply pipe 2 is used to transport gas. The gas moves from the gas source to the baking pan 1 through the gas supply pipe 2 and is ignited in the baking tank 11. The gas continues to burn to provide heat for baking the molten iron ladle. The gas can be coal gas, natural gas or other combustible gases that are easy to heat the molten iron ladle. It is worth noting that a gas head is provided at the end of the gas supply pipe 2 near the baking pan 1. The gas supply pipe 2 is equipped with valves, backfire prevention and other components.

[0032] One end of the air duct 3 is connected to the fan, which is used to supply air. The other end of the air duct 3 extends into the baking oven 11 and is connected to the baking oven 11. The air duct 3 is located on one side of the gas supply pipe 2. The air supplied by the fan is transported to one side of the gas supply pipe 2 through the air duct 3, thereby assisting combustion when the gas is burning. The air duct 3 can also supply oxygen into the baking oven 11 through the fan, thereby improving combustion efficiency, making the fuel burn more completely, and thus reducing gas consumption.

[0033] The air guide plate 4 is installed at one end of the air duct 3 near the baking tray 1. The air guide plate 4 is located inside the baking chamber 11. One end of the air guide plate 4 extends towards the axis of the gas supply pipe 2. After the air is discharged through the air duct 3, it is blocked by the air guide plate 4 and moves towards the gas supply pipe 2, thereby increasing the oxygen content of the gas combustion in the baking chamber 11, so that the gas combustion is more complete and the combustion effect is improved.

[0034] With the above structure, the molten iron ladle baking device provided by this utility model allows the molten iron ladle to be baked to be brought close to the baking device during use. Then, a gas source supplies gas through the gas supply pipe 2, and the supplied gas is ignited in the baking tank 11 to heat the molten iron ladle. Simultaneously, an air duct 3 supplies air into the baking tank 11 through the gas supply pipe 2 to assist the combustion of the gas. A guide plate 4 guides the air discharged from the air duct 3, allowing the discharged air to move towards the gas supply pipe 2, thereby causing more oxygen to gather at the combustion site and better assisting combustion during baking. Therefore, this molten iron ladle baking device, through the air duct 3 and the guide plate 4, directs more oxygen to the combustion site, making the gas combustion more complete, the baking efficiency higher, and reducing gas consumption.

[0035] An optional implementation of this embodiment is as follows: In order to facilitate the adjustment of the angle of the air guide plate 4, the molten iron ladle baking device also includes a rotating part 5. The rotating part 5 is set on the air duct 3, and one side of the air guide plate 4 is rotatably mounted on the rotating part 5, so that the rotating part 5 drives the air guide plate 4 to rotate, thereby adjusting the angle between the air guide plate 4 and the extension direction of the gas supply pipe 2. The angle of the air guide plate 4 is adjusted according to the usage requirements, so that the air discharged from the air duct 3 is closer to the gas outlet and further away from the gas outlet, thereby reducing the influence of the air duct 3 on the direction of gas combustion.

[0036] An optional implementation of this embodiment is as follows: In order to facilitate the adjustment of the angle of the air guide plate 4, the molten iron ladle baking device also includes an adjusting block 6. The adjusting block 6 is slidably installed on the baking tray 1. The air guide plate 4 is connected to the adjusting block 6. The adjusting block 6 slides, thereby driving the air guide plate 4 to rotate, so as to change the angle of the air guide plate 4. The adjusting block 6 stops rotating, thereby fixing the angle of the air guide plate 4, so that the air guide plate 4 guides the air of the air duct 3 at a fixed angle.

[0037] An optional implementation of this embodiment is as follows: the distance between the section block and the duct 3 gradually increases from one end of the adjusting block 6 to the other end. The air guide plate 4 is located between the duct 3 and the adjusting block 6, and the air guide plate 4 abuts against the adjusting block 6. The adjusting block 6 slides relative to the air guide plate 4 to push the air guide plate 4 to rotate. Specifically, when the adjusting block 6 rotates, the distance between the adjusting block 6 and the duct 3 gradually decreases, thereby causing the adjusting block 6 to push one end of the air guide plate 4 to move towards the duct 3. Since the air guide plate 4 is rotatably connected to the duct 3, Therefore, the end of the air guide plate 4 away from the adjusting block 6 rotates away from the axis of the air duct 3, thereby guiding the exhaust air from the air duct 3 towards the direction of the air supply pipe 2 away from the baking tray 1; when the adjusting block 6 rotates, the distance between the adjusting block 6 and the air duct 3 gradually increases, thereby causing the adjusting block 6 to drive the air guide plate 4 to move away from the air duct 3, and the end of the air guide plate 4 away from the adjusting block 6 rotates towards the axis of the air duct 3, thereby guiding the exhaust air from the air duct 3 towards the direction of the air supply pipe 2 towards the baking tray 1.

[0038] An optional implementation of this embodiment is as follows: the air guide plate 4 is provided with a groove 41, and the rotating part 5 is slidably installed in the groove 41. The rotating part 5 slides relative to the air guide plate 4 to adjust the length of the air guide plate 4 extending out of the air duct 3.

[0039] An optional implementation of this embodiment is as follows: The adjusting block 6 is provided with a guide groove 61 on the side near the air duct 3. One end of the air guide plate 4 is slidably installed in the guide groove 61. The adjusting block 6 moves so that the air guide plate 4 moves along the guide groove 61, thereby adjusting the length of the air guide plate 4 extending out of the air duct 3. The length of the air guide plate 4 extending out of the air duct 3 increases, thereby making the air guide plate 4 guide the air discharged from the air duct 3 for a longer length. The length of the air guide plate extending out of the air duct 3 decreases, thereby making the air guide plate 4 guide the air discharged from the air duct 3 for a shorter length.

[0040] An optional implementation of this embodiment is as follows: The distance between the guide groove 61 and the baking tray 1 gradually decreases from the end of the adjusting block 6 near the air duct 3 to the other end; specifically, when the adjusting block 6 rotates, the distance between the adjusting block 6 and the air duct 3 gradually decreases, thereby causing the adjusting block 6 to push one end of the air guide plate 4 towards the air duct 3, and the end of the air guide plate 4 away from the adjusting block 6 to rotate away from the axis of the air duct 3. At the same time, the length of the air guide plate 4 extending out of the air duct 3 increases, causing the air duct 3 to move the discharged air towards the air supply pipe 2 away from the baking tray 1. When the air force provided by the air duct 3 increases, this not only extends the guiding distance of the air to the air duct 3. This also reduces the impact of air from duct 3 on gas delivery to pipe 2, thereby reducing interference during gas combustion. When the adjusting block 6 rotates, the distance between the adjusting block 6 and duct 3 gradually increases, causing the adjusting block 6 to move one end of the air guide plate 4 away from duct 3, and the end of the air guide plate 4 away from the adjusting block 6 to rotate closer to the axis of duct 3. This guides the exhaust air from duct 3 towards pipe 2 and closer to baking tray 1. At the same time, the area of ​​the air guide plate 4 extending out of duct 3 decreases. When the air force provided by duct 3 decreases, this allows the exhaust air from duct 3 to move more concentrated towards the exhaust pipe for better combustion.

[0041] An optional implementation of this embodiment is as follows: The baking tank 11 is provided with multiple gas supply pipes 2 and air ducts 3. The multiple gas supply pipes 2 transport gas to increase the heat exchange area, thereby better baking the molten iron ladle. The gas supply pipes 2 are evenly distributed along the circumference of the baking tray 1 to form a baking area, so that the molten iron ladle is heated evenly. The air ducts 3 correspond one-to-one with the gas supply pipes 2, so that the gas in each gas supply pipe 2 can be supplemented with oxygen through the air duct 3 when burning, thereby improving the combustion effect. Correspondingly, the air guide plate 4 and the adjusting block 6 are one-to-one with the air ducts 3.

[0042] An optional implementation of this embodiment is as follows: In order to facilitate the rotation of the driving adjustment block 6, the molten iron ladle baking device is rotatably installed on the baking tray 1. The adjustment block 6, the gas supply pipe 2 and the air pipe 3 are all installed inside the driving ring 7. A baking groove 11 is formed inside the driving ring 7. Multiple adjustment blocks 6 are installed on the inner wall of the driving ring 7. When the driving ring 7 rotates, it drives multiple adjustment blocks 6 to rotate, thereby causing multiple air guide plates 4 to move and rotate synchronously.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
