Description

Technical Field

[0001] This utility model relates to the field of industrial technology, and in particular to a safe discharge device for molten aluminum from a smelting furnace. Background Technology

[0002] Global aluminum consumption continues to rise. As the world's largest aluminum producer, China is increasingly using aluminum alloys in aerospace, new energy vehicles, and high-end equipment manufacturing. These fields have extremely high requirements for the purity and casting precision of molten aluminum. Traditional extensive emission methods are difficult to meet the needs of new processes such as precision casting and continuous casting. There is an urgent need for safer and more controllable emission devices to ensure production quality.

[0003] The device consists of a discharge unit, control and regulation, safety protection, monitoring and sensing, cooling and protection components. Through the normal discharge process of "preparation, control and monitoring", combined with the emergency mechanisms of abnormal cut-off, explosion-proof pressure relief and manual intervention, and based on the design of leakage prevention, high temperature resistance, automatic interlocking and emergency redundancy, it realizes the safe and orderly discharge of aluminum liquid.

[0004] In existing technologies, some smelting furnaces lack a stable adjustment angle. When the molten aluminum in the furnace is sufficient, the liquid level is high and the pressure is large. The molten aluminum will impact the discharge port or receiving container at high speed. The excessive impact force can easily cause the molten aluminum to splash. The furnace body will shake due to uneven force, resulting in molten aluminum spillage. Manual adjustment has poor precision and is prone to sudden changes in angle, which can cause sudden increases or decreases in flow rate. Personnel need to operate near the high-temperature furnace body for a long time, exposed to heat radiation and the risk of molten aluminum splashing, which significantly increases the difficulty of labor protection. Therefore, a safe discharge device for molten aluminum in smelting furnaces is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a safe discharge device for molten aluminum from a smelting furnace. It aims to improve the problems in the existing technology where smelting furnaces require manual adjustment with poor precision, which can easily lead to sudden changes in angle affecting the flow rate. Personnel also need to operate at close range and face the risks of heat radiation and splashing, making labor protection difficult.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A safe discharge device for molten aluminum from a smelting furnace includes a support plate. An electric push rod is fixedly connected to the top of each support plate.

[0023] 1. In this utility model, the driving end of the electric push rod drives the sliding rod to rotate the rotating rod. When the rotating rod drives the sliding shaft, the rotating rod is fixed to the support frame for stability. At the same time, the sliding shaft is fixed on both sides of the melting tank on the same side. By adjusting the tilt angle of the melting furnace, the "pressure" of the aluminum liquid outflow can be directly controlled. The smaller the angle, the slower the aluminum liquid outflow speed and the smaller the flow rate. The larger the angle, the more steadily the flow rate increases. This adjustment can ensure that the aluminum liquid enters the discharge channel or receiving container at a controllable flow rate, reducing the risk of splashing and leakage from the source. This is the core function of safety protection.

[0024] 2. In this utility model, pulling the sliding rod two causes the connecting plate one to move backward and compress the spring, thereby causing the fixed shaft two to rotate and drive the connecting rod. At the same time, the fixed shaft one rotates within the connecting plate two, accurately positioning the high-pressure nozzle to the cleaning area of ​​the outlet frame and keeping it fixed. This extends the life of the equipment components, reduces wear, increases the emission speed in production, shortens downtime, reduces the risk of boiling over, and reduces pollutant emissions, making it both safe and environmentally friendly. It also controls the introduction of impurities in product quality and improves the yield rate of castings. Attached Figure Description

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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a safe discharge device for molten aluminum from a smelting furnace, comprising a support plate 2. Each support plate 2 has an electric push rod 3 fixedly connected to its top. The support plate 2 supports the electric push rod 3 to ensure stability. Each electric push rod 3 has a sliding rod 4 fixedly connected to its drive end. The electric push rod 3 pushes the sliding rod 4 to rotate a rotating rod 5. The sliding rod 4 is rotatably connected to the outside of the rotating rod 5. When the sliding rod 4 is pushed, the rotating rod 5 is driven to rotate. A sliding shaft 6 restricts the direction of movement of the rotating rod 5. The rotating rod 5 has a sliding shaft 6 rotatably connected inside its interior. The sliding shaft 6 slides in an arc-shaped groove 9 to adjust the tilt angle. Each rotating rod 5 has a support frame 8 fixedly connected to its exterior. The support frame 8 has a support rod 10 fixedly connected inside its interior. The support frame 8 fixes the sliding shaft 6 to prevent the smelting tank 1 from falling. Each sliding shaft 6 has a support block 22 slidably connected to its exterior. An arc-shaped groove 9 is provided to provide a motion environment for the sliding shaft 6. A smelting tank 1 is fixedly connected to the front side of the support rod 10. A base 7 is fixedly connected to the bottom of the smelting tank 1. A water tank 23 is fixedly connected to the top of the base 7. A water pipe 11 is fixedly connected to the top of the water tank 23. The water pipe 11 draws water out of the water tank 23. A high-pressure nozzle 19 is fixedly connected to the outside of the water pipe 11. The high-pressure nozzle 19 outputs water through the water pipe 11. The outside of the high-pressure nozzle 19 is in contact with the inside of the fixing frame 21. The fixing frame 21 fixes the high-pressure nozzle 19 in a slot. Arc-shaped grooves 9 are provided inside the support blocks 22. The opposite sides of the support plate 2 are fixedly connected to the adjacent sides of the support blocks 22. The support plate 2 is used to support the electric push rod 3. The bottom of the support block 22 is fixedly connected to the top of the base 7. The base 7 provides stability for the whole device. A fixed cleaning component is fixedly connected to the front side of the smelting tank 1.

[0034] Reference Figure 4 , Figure 5The cleaning assembly includes an outlet frame 12, the rear of which is fixedly connected to the front of the molten ladle 1. The outlet frame 12 facilitates the pouring out of molten aluminum. Two fixing plates 24 are fixedly connected to the top of the outlet frame 12, providing support for the cleaning device. Sliding rods 13 are slidably connected inside each fixing plate 24, and the outer surface of each sliding rod 13 is fitted inside a spring 14, providing power to the spring 14. The left and right sides of the molten ladle 1 are fixedly connected to adjacent sides of sliding shafts 6. To prevent the molten ladle 1 from sliding forward, connecting plates 15 are fixedly connected to adjacent sides of sliding rods 13 on both sides of the sliding shafts 6. Pulling the sliding rods 13 causes the connecting plates 15 to provide a movement track for subsequent parts. Springs 14 are fixedly connected to the far side of connecting plate 15. The compression force of springs 14 is transmitted to connecting rod 18 through fixed shaft 20. Fixed shaft 20 is rotatably connected inside connecting plate 15. Connecting rod 18 is fixedly connected to the outside of fixed shaft 20. Fixed frame 21 is fixedly connected to the near side of connecting rod 18. Fixed shaft 16 is fixedly connected inside connecting rod 18. Fixed shaft 16 slides in the groove of connecting plate 27 to ensure that the movement trajectory of connecting rod 18 is stable and controllable. Connecting plate 27 is rotatably connected to the front side of fixed shaft 16. The bottom of connecting plate 27 is fixedly connected to the top of outlet frame 12. Fixed plate 24 is fixedly connected to the far side of connecting plate 27.

[0035] Working principle: When the molten aluminum is poured out, the support rod 10 fixes the molten furnace 1. The electric push rod 3 is activated, and its drive end drives the sliding rod 4 to rotate the rotating rod 5. As the rotating rod 5 drives the sliding shaft 6, the other end of the rotating rod 5 rises, allowing the sliding shaft 6 to slide stably in the arc groove 9 to control the angle at which the molten aluminum is poured out. The rotating rod 5 is fixed to the support frame 8 for stability. At the same time, the sliding shaft 6 is fixed on both sides of the molten furnace 1 to maintain stability. The molten furnace 1 is fixed to the support blocks 22 on both sides by the rotating shafts on both sides to support the main body. By adjusting the tilt angle of the molten furnace, the "pressure" of the molten aluminum can be directly controlled. The smaller the angle, the slower the flow rate and the smaller the flow rate. The larger the angle, the more steadily the flow rate increases. This adjustment ensures that the molten aluminum enters the discharge channel or receiving container at a controllable flow rate, reducing the risk of splashing and leakage from the source. This is the core function of safety protection.

[0036] After the molten aluminum is discharged through the outlet rack 12, it needs to be cleaned in time to prevent residual molten aluminum from solidifying and clogging the channel. The water stored in the water tank 23 is transported to the high-pressure nozzle 19 through the high-pressure water pipe 11. Pulling the sliding rod 13 causes the connecting plate 15 to move backward and compress the spring 14, thereby causing the fixed shaft 20 to rotate and drive the connecting rod 18. At the same time, the fixed shaft 16 rotates in the connecting plate 17. The rotation of the connecting rod 18 causes the fixed frame 21 fixed on it to move synchronously, accurately positioning the high-pressure nozzle 19 to the area to be cleaned on the outlet rack 12 and keeping it fixed. After cleaning, the operator releases the sliding rod 13, the spring 14 releases its elastic potential energy, and drives the entire mechanism to reset, waiting for the next cleaning command. The entire cleaning process greatly improves the cleaning efficiency and maintenance convenience of the outlet rack 12, extends the life of the equipment components, reduces wear, increases the discharge speed in production, shortens downtime, reduces the risk of boiling over, and reduces pollutant emissions. It is both safe and environmentally friendly, and controls the introduction of impurities in product quality and improves the yield of castings.
