Description

Technical Field

[0001] This utility model relates to a draining mechanism for an iron and steel furnace, belonging to the technical field of iron and steel smelting equipment. Background Technology

[0002] A steel furnace is a barrel-shaped furnace used to melt metals. It can heat the metals to a molten state at high temperatures for smelting operations. After the steel furnace has finished melting, the molten steel needs to be discharged for subsequent smelting operations. In the existing technology, the furnace is hoisted up and the liquid is discharged by tilting the furnace.

[0003] Publication number CN219890171U discloses a draining mechanism for a steel furnace. This mechanism includes two parallel, detachable support rods mounted on a base plate, with a reciprocating, detachable draining assembly located between the tops of the two support rods. During draining, the drain pipe swings up and down under the drive of a large gear. The draining ladle of the drain pipe extends into the furnace. When the ladle swings downwards, it enters the molten steel; when it swings upwards, it scoops up the molten steel. At this time, the other end of the drain pipe swings downwards, and under the gravity of the molten steel, it flows along the drain pipe... The pipe flows to the other end for drainage. A draining ladle can be used to scoop out a measured amount of molten steel for drainage, which is convenient for making small steel workpieces. At the same time, the drainage does not need to overcome the gravity of the steel furnace, which can save energy. However, in the existing technology, smaller boilers usually use pipes connected to the boiler body to drain the liquid. During the drainage process, the pipes are prone to damage due to sudden temperature changes. At the same time, impurities can accumulate in the pipes over a long period of time, making it impossible to drain the liquid normally. There is an urgent need for a drainage mechanism for steel furnaces to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a draining mechanism for a steel furnace to solve the problems mentioned in the background. This utility model avoids the problem of device damage caused by large temperature difference when the pipeline is in contact with the liquid, and the problem of failure to drain normally due to the accumulation of impurities.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a draining mechanism for a steel furnace, comprising a steel furnace body, a fixing block provided on the circumferential surface of the steel furnace body, a placement groove provided on one side end of the fixing block, a threaded rod provided in the placement groove, a first gear fixedly connected to one side end of the threaded rod, a second gear provided on the circumferential surface of the first gear, a connecting rod provided on the circumferential surface of the threaded rod, a scraper fixedly connected to one side end of the connecting rod, and a motor provided at the bottom end of the fixing block.

[0006] Furthermore, the circumferential surface of the steel furnace body is provided with a liquid outlet pipe, the scraper is located on one side of the inner wall of the liquid outlet pipe, and a groove matching the connecting rod is opened on one side of the inner wall of the liquid outlet pipe.

[0007] Furthermore, a liquid inlet pipe is fixedly connected to the top of the steel furnace body, and an exhaust pipe is fixedly connected to the top of the steel furnace body.

[0008] Furthermore, the bottom end of the exhaust pipe is provided with an air outlet, and the bottom end of the exhaust pipe is located at the top of the liquid outlet pipe.

[0009] Furthermore, a liquid storage tank is provided on one side of the steel furnace body, and multiple support legs are fixedly connected to the bottom of the steel furnace body.

[0010] Furthermore, the second gear is fitted onto the circumferential surface of the motor.

[0011] The beneficial effects of this utility model are as follows: The draining mechanism of the steel furnace of this utility model, due to the addition of scraper, gas pipe, gear, threaded rod and connecting rod, after our design improvement and actual use, shows that the device has a reasonable structure and good practicality.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a draining mechanism for a steel furnace, including a steel furnace body 1, a fixing block 4 on the circumferential surface of the steel furnace body 1, a placement groove 9 on one side of the fixing block 4, a threaded rod 8 in the placement groove 9, a first gear 12 fixedly connected to one side of the threaded rod 8, a second gear 13 on the circumferential surface of the first gear 12, a connecting rod 11 on the circumferential surface of the threaded rod 8, a scraper 10 fixedly connected to one side of the connecting rod 11, and a motor 14 at the bottom of the fixing block 4. This design solves the problems of damage caused by large temperature differences when the pipeline comes into contact with liquid in the original device, and the inability to drain normally due to the accumulation of impurities.

[0020] As the first embodiment of this utility model: a liquid outlet pipe 5 is provided on the circumferential surface of the steel furnace body 1. A scraper 10 is provided on one inner wall of the liquid outlet pipe 5. A groove matching the connecting rod 11 is opened on one inner wall of the liquid outlet pipe 5. In this device, the connecting rod 11 can be stably installed in the liquid outlet pipe 5. At the same time, the scraper 10 can effectively remove the residue on the inner wall of the pipe, ensuring smooth liquid discharge, improving the working efficiency and maintenance convenience of the equipment. A liquid inlet pipe 2 is fixedly connected to the top of the steel furnace body 1, and an exhaust pipe 3 is fixedly connected to the top of the steel furnace body 1. The liquid is accurately introduced into the furnace through the liquid inlet pipe 2, while the exhaust pipe 3 can effectively discharge the gas generated during the smelting process, ensuring operational safety and optimizing the working environment, thereby improving the efficiency and safety of the entire smelting process. The exhaust pipe 3 has an outlet at its bottom, which is located at the top of the liquid outlet pipe 5. This ensures that the exhaust pipe 3 can directly guide gas out of the furnace, while preventing interference between the gas and the liquid in the liquid outlet pipe 5. This ensures that the temperature remains stable and prevents damage to the device due to excessive temperature differences, guaranteeing smooth and safe exhaust and liquid discharge processes, and improving the stability and efficiency of equipment operation. A liquid storage tank 7 is located on one side of the steel furnace body 1. Multiple support legs 6 are fixedly connected to the bottom of the steel furnace body 1. The liquid storage tank 7 provides additional liquid storage space for easy management and use. The multiple support legs 6 ensure the overall stability of the furnace and good ground contact, improving operational safety and placement flexibility. The second gear 13 is fitted onto the circumferential surface of the motor 14. The second gear 13 can be directly driven by the motor 14, achieving efficient power transmission while simplifying the mechanical structure, reducing energy loss, and improving the system's operating efficiency and reliability.

[0021] As a second embodiment of this utility model: the motor 14 drives the gear system to rotate the threaded rod 8, enabling the scraper 10 on the connecting rod 11 to effectively remove impurities from the inner wall of the pipeline. This solves the problem of thermal stress damage caused by the large temperature difference when the pipeline comes into contact with the liquid in the original device, and overcomes the problem of poor drainage caused by impurity accumulation. In addition, this design reduces the need for manual maintenance and lowers operating costs through regular automatic cleaning. At the same time, the continuous operation of the scraper 10 ensures that the inside of the pipeline remains clean, improving fluid transmission efficiency and further enhancing the overall performance of the equipment. More importantly, this solution significantly improves the stability and reliability of equipment operation, extends its service life, and provides a safer and more efficient solution for industrial production.
