Description

Technical Field

[0001] This utility model belongs to the technical field of non-ferrous metal smelting equipment, and relates to an oxygen-enriched side-blown smelting furnace. Background Technology

[0002] In industrial fields such as non-ferrous metal smelting, oxygen-enriched side-blown smelting furnaces have become a widely used key equipment due to their high efficiency and environmental protection advantages. With the continuous expansion of industrial production scale and the increasing requirements for production efficiency and product quality, the stability and reliability of oxygen-enriched side-blown smelting furnaces during operation are becoming increasingly important.

[0003] In the actual operation of oxygen-enriched side-blown melting furnaces, temperature control is an extremely critical factor. Because a large amount of heat is generated during the melting process, it is sometimes necessary to cool it down in time to ensure the normal operation of the equipment, extend its service life, and ensure product quality. However, the cooling process cannot be too fast, otherwise it may cause the furnace material to be damaged due to excessive thermal stress, affecting the long-term stable operation of the equipment.

[0004] The existing cooling method used in some oxygen-enriched side-blown smelting furnaces is to install cooling water pipes on the outer wall of the furnace. When using this traditional cooling method, on the one hand, the temperature of the water gradually increases as it circulates in the pipes, and the heat exchange efficiency decreases accordingly. This is not conducive to timely and effective cooling of the smelting furnace and cannot meet the needs of some production scenarios with high requirements for timely cooling. On the other hand, in order to maintain the cooling effect, it is necessary to continuously replace and cool the water, which not only wastes a lot of water resources, but also increases production costs as well as the energy consumption and maintenance costs of the cooling system. Utility Model Content

[0005] The technical problem this invention aims to solve is that when water circulates in the water pipe, its own temperature gradually increases with the furnace temperature, and the heat exchange efficiency decreases accordingly. This is not conducive to timely and effective cooling of the smelting furnace. In order to maintain the cooling effect, it is necessary to continuously replace and cool the water, which not only wastes a lot of water resources, but also increases production costs as well as the energy consumption and maintenance costs of the cooling system.

[0006] The present invention discloses an oxygen-enriched side-blown smelting furnace, comprising a furnace body, several water tanks arranged on the outer side of the furnace body, including three water tanks. Connecting rods are symmetrically and movably connected to the two sides of each water tank away from its center. A connecting plate is movably connected to one side of each connecting rod, and the connecting plate is fixedly connected to the outer wall of the furnace body. A lifting mechanism is provided at the top of the furnace body, and is fixedly connected to the top of each water tank. The lifting mechanism is used to raise or lower the water tanks. A connecting component is provided between the three water tanks to connect their interiors.

[0007] Preferably, the lifting mechanism includes a mounting plate, which is provided above the smelting furnace body. A screw hole is provided at the top of the mounting plate, and a screw rod is installed in the screw hole. A bearing seat is installed below the mounting plate at the bottom end of the screw rod. The bottom of the bearing seat is fixedly connected to the top of the smelting furnace body. A circular plate is fixedly connected above the mounting plate at the top end of the screw rod. Evenly distributed rectangular openings are provided at the top of the mounting plate. An inclined pull plate is movably connected between the inner walls of the two sides of the rectangular openings. A fixed plate is movably connected to one side of the inclined pull plate near the water tank. The bottom of the fixed plate is fixedly connected to the top of the water tank. A transmission mechanism is provided on the side wall of the screw rod, which drives the screw rod to rotate.

[0008] Preferably, the transmission mechanism includes a worm gear, which is fixedly connected to the side wall of the screw near the bottom. A positioning plate is fixedly connected to the top of the smelting furnace body. Two positioning plates are provided, and a worm is movably connected between the two positioning plates. The worm meshes with the worm gear. A servo motor is installed on one side of the positioning plate. The output end of the servo motor passes through the positioning plate and is movably connected to the positioning plate. The output end of the servo motor is fixedly connected to the worm.

[0009] Preferably, the connecting component includes a water distribution pipe. A water distribution pipe is installed near the bottom between the three water tanks and is connected to the interior of the water tank. A water inlet pipe is installed near the top of one of the water tanks on the side away from the furnace body and is connected to the interior of the water tank. Drain pipes are installed near the bottom of the water tanks on both sides of the furnace body on the side away from the center of the furnace body and are connected to the interior of the water tank. A valve is installed on the drain pipe.

[0010] Furthermore, a limiting plate is fixedly connected to the top of the smelting furnace body, and the top of the limiting plate passes through a rectangular opening and extends above the mounting plate.

[0011] Furthermore, each of the three water tanks has a number of evenly distributed heat dissipation fins fixedly connected to the side of the furnace body away from it.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes the coordinated operation of water tanks, connecting rods, inlet pipes, distribution pipes, heat sinks, servo motors, mounting plates, and screws. When cooling is required, the servo motor drives the mounting plate to descend, bringing multiple water tanks into contact with the outer wall of the smelting furnace. Through the physical principle of heat conduction, the furnace body is cooled. When cooling is not needed, the water tanks can be moved away from the furnace body, allowing the water to cool naturally. This allows for recycling and effectively solves the problem of reduced heat exchange efficiency and water waste caused by fixed contact between water pipes and the furnace body.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] like Figures 1 to 7 As shown, the furnace includes a smelting furnace body 1. Several water tanks 2 are arranged on the outside of the smelting furnace body 1. There are three water tanks 2. Connecting rods 3 are symmetrically and movably connected to the two sides of the water tanks 2 that are far from the center of the water tanks 2. A connecting plate 4 is movably connected to one side of the connecting rod 3. The connecting plate 4 is fixedly connected to the outer wall of the smelting furnace body 1. A lifting mechanism is arranged on the top of the smelting furnace body 1. The lifting mechanism is fixedly connected to the top of the water tanks 2. The lifting mechanism is used to pull the water tanks 2 up or down. A connecting component is arranged between the three water tanks 2. The connecting component is used to connect the interiors of the three water tanks 2.

[0026] The smelting furnace body 1 in this technical solution is a common oxygen-enriched side-blown smelting furnace on the market. Its usage and working principle are common knowledge among those in the field, so they will not be described in detail in this technical solution. The water tank 2 is made of stainless steel, which has high strength, corrosion resistance and heat resistance, and high efficiency in heat conduction, making it relatively stable in use.

[0027] like Figures 2-7 As shown, the lifting mechanism includes a mounting plate 10. A mounting plate 10 is positioned above the smelting furnace body 1. A screw hole 11 is formed at the top of the mounting plate 10, and a screw rod 12 is installed inside the screw hole 11. A bearing seat 22 is installed below the mounting plate 10 at the bottom end of the screw rod 12. The bottom of the bearing seat 22 is fixedly connected to the top of the smelting furnace body 1. A circular plate 20 is fixedly connected above the mounting plate 10 at the top end of the screw rod 12. Evenly distributed rectangular openings 13 are formed at the top of the mounting plate 10. An inclined pull plate 14 is movably connected between the inner walls of both sides of the rectangular openings 13. A fixed plate 15 is movably connected to one side of the inclined pull plate 14 near the water tank 2. The bottom of screw 15 is fixedly connected to the top of water tank 2. A transmission mechanism is provided on the side wall of screw 12. The transmission mechanism is used to drive screw 12 to rotate. The transmission mechanism includes worm gear 16. Worm gear 16 is fixedly connected to the side wall of screw 12 near the bottom. A positioning plate 17 is fixedly connected to the top of smelting furnace body 1. There are two positioning plates 17. Worm 18 is movably connected between the two positioning plates 17. Worm 18 meshes with worm gear 16. A servo motor 19 is installed on one side of positioning plate 17. The output end of servo motor 19 passes through positioning plate 17 and is movably connected to positioning plate 17. The output end of servo motor 19 is fixedly connected to worm 18.

[0028] The servo motor 19 in this technical solution is a type of motor that can precisely control its position, speed, and acceleration. It can convert voltage signals into torque and speed to drive the controlled object. It is often used as an actuator in automatic control systems. The servo motor 19 can more accurately control the height of the mounting plate 10 when it is raised or lowered. The lifting mechanism can drive the water tank 2 to rise or fall, so that the water tank 2 can contact and separate from the smelting furnace body 1. When separated, the water in the water tank 2 can cool down naturally, so as to cool down the smelting furnace body 1, thereby avoiding the waste of resources caused by frequent water changes.

[0029] like Figures 1-5 As shown, the connecting components include a water distribution pipe 6. A water distribution pipe 6 is installed near the bottom between the three water tanks 2. The water distribution pipe 6 is connected to the inside of the water tank 2. A water inlet pipe 5 is installed near the top on the side of one of the water tanks 2 that is far from the center of the smelting furnace body 1. The water inlet pipe 5 is connected to the inside of the water tank 2. Drainage pipes 8 are installed near the bottom on the side of the water tanks 2 located on both sides of the smelting furnace body 1 that is far from the center of the smelting furnace body 1. The drainage pipes 8 are connected to the inside of the water tank 2. A valve 9 is installed on the drainage pipe 8.

[0030] The water distribution pipe 6 in this technical solution is made of flexible hose, specifically polytetrafluoroethylene (PTFE). This material has extremely high high-temperature resistance and can be used for a long time in a temperature range of -180℃ to 260℃. It has excellent chemical stability, hardly reacts with any chemical substances, and also has a low coefficient of friction, good electrical insulation and self-lubricating properties, making it relatively stable in use. Because the three water tanks 2 will move away from the melting furnace body 1 when they rise, the water distribution pipe 6 will change shape, so a flexible hose is required to avoid tearing and breakage.

[0031] Among them, a limiting plate 21 is fixedly connected to the top of the smelting furnace body 1. The top of the limiting plate 21 passes through the rectangular opening 13 and extends above the mounting plate 10. The limiting plate 21 can further restrict the rotation of the mounting plate 10, so that when the screw 12 is rotated, the mounting plate 10 will not rotate with it, thus playing a limiting role.

[0032] In addition, several evenly distributed heat dissipation fins 7 are fixedly connected to the side of the three water tanks 2 that is away from the furnace body 1. The heat dissipation fins 7 are made of the same material as the water tanks 2, which can improve the heat exchange efficiency and increase the cooling speed of the water in the water tanks 2.

[0033] Working Principle: In use, this utility model first starts the servo motor 19 through an external power supply. The servo motor 19 drives the worm gear 18 to rotate forward, which in turn drives the worm wheel 16 and the screw 12 to rotate forward. This causes the mounting plate 10 to lift the inclined pull plate 14, thus simultaneously lifting the three water tanks 2. When the water tanks 2 rise, multiple connecting rods 3 swing upward. During the upward movement, the water tanks 2 also move away from the furnace body 1, thus separating the water tanks 2 from the outer wall of the furnace body 1. When the connecting rods 3 on the water tanks 2 swing to a horizontal position, the servo motor 19 stops. Next, the external water source is connected to the water inlet pipe 5 and fixed in place. If necessary, a water pipe is installed on the drain pipe 8 to facilitate water recycling. Then, cool water enters one of the water tanks 2 through the water inlet pipe 5, and then the water is transported to the other two water tanks 2 through the water distribution pipe 6. After all three water tanks 2 are full, the water filling stops, and the system can then be used normally.

[0034] If the smelting furnace body 1 needs to be cooled during use, the servo motor 19 can be started by an external power supply. The servo motor 19 drives the worm gear 18 to reverse, which in turn drives the worm wheel 16 and the screw 12 to reverse, causing the mounting plate 10 and the inclined pull plate 14 to descend. Through the thrust of the inclined pull plate 14 and the weight of the water tank 2, the water tank 2 descends synchronously with the mounting plate 10 until the outer wall of the water tank 2 contacts the outer wall of the smelting furnace body 1. Then the servo motor 19 is turned off. Heat exchange occurs between the water tank 2 and the smelting furnace body 1 through physical heat conduction, thereby achieving the effect of cooling the smelting furnace body 1. After cooling is completed, the water tank 2 is raised again through the above operation, so that the water tank 2 is no longer in contact with the smelting furnace body 1. In this way, the water in the water tank 2 will cool down naturally for reuse.

[0035] When cooling the furnace body 1, the water in the water tank 2 may boil, which greatly reduces the heat exchange efficiency. At this time, the valve 9 on the drain pipe 8 can be opened to drain the hot water, and then cold water can be injected through the inlet pipe 5 via an external water source. This can increase the continuous cooling effect. The drained hot water can be recycled and reused, which can effectively solve the problem of high water temperature and low heat exchange efficiency when cooling is required due to the fixed connection between the water pipe and the furnace body 1.

[0036] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
