Description

Technical Field

[0001] The utility model belongs to the technical field of converter smelting, and particularly relates to a clogging prevention device for the charging opening of a converter. Background Art

[0002] In the iron and steel smelting industry, converter smelting is a crucial process. However, during this process, intense chemical reactions often lead to the occurrence of steel slag splashing and slag overflow. These splashed steel slags have extremely high temperatures and adhesiveness, and are extremely likely to adhere to the periphery of the charging opening of the converter. In addition, if the raw materials are wet, the raw materials are prone to sticking to each other during the charging process, further increasing the risk of clogging. Over time, these adhesives and adhesions continue to accumulate, and may ultimately lead to serious clogging of the charging opening.

[0003] The clogging of the charging opening not only brings great difficulties to the daily cleaning work, but also seriously affects the normal charging operation of the converter. Once the charging opening is clogged, the smelting process cannot proceed smoothly, resulting in a reduction in production efficiency and an increase in costs. More seriously, the clogging may cause potential safety hazards in extreme cases, posing a threat to the safety of operators and equipment.

[0004] In view of the above problems, there is an urgent need for a device in the existing converter smelting technology that can effectively prevent the clogging of the charging opening. To solve the above technical problems, improve the smelting efficiency, reduce the production cost, and ensure the safe progress of the smelting process. Summary of the Utility Model

[0005] Aiming at the problems existing in the prior art, the utility model provides a clogging prevention device for the charging opening of a converter. This device needs to be able to timely remove the steel slag and adhesions adhering to the periphery of the charging opening without affecting the normal smelting operation, ensuring the smoothness of the charging opening.

[0006] The utility model is realized as follows. A clogging prevention device for the charging opening of a converter includes a charging pipe for adding materials to the converter, and is characterized in that: a pneumatic purging disc or pipe is installed on the end face of the charging opening of the charging pipe, and air injection holes are provided on the pneumatic purging disc or pipe facing the direction of the steel slag, and several air injection holes are provided along the circumferential direction; the pneumatic purging disc or pipe is connected to a high-pressure nitrogen gas source through a delivery pipe, and a gas source control valve is installed on the delivery pipe.

[0007] Further preferably, the center of the air injection hole forms an inclination angle of 0-30° with the center line of the charging opening.

[0008] Further preferably, a vibrator is installed near the charging opening, and the vibrator is connected to a control switch through a wire.

[0009] Further preferably, 2-6 vibrators are provided along the circumferential direction of the feeding pipe.

[0010] The advantages and technical effects of the present utility model: A clogging prevention device for the charging port of a converter integrates multiple efficient anti-clogging technologies, significantly improving the smelting efficiency and equipment stability. The device uses a pneumatic purging disk or pipe to strongly purge the charging port with high-pressure nitrogen, effectively removing steel slag and debris to prevent clogging. The special design of the air injection holes, including uniform distribution along the circumferential direction and an inclination angle of 0-30°, ensures the full coverage and efficient impact of the purging gas, greatly improving the removal efficiency. The device is also equipped with a vibrator to further enhance the anti-clogging effect. By vibrating to loosen and shed the adherents, the anti-clogging effect is further enhanced.

[0015] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0016] Embodiment 1, please refer to Figure 1 and Figure 2, A clogging prevention device for the charging port of a converter, comprising a charging pipe 1 for adding materials to the converter. The charging pipe is the main channel for material addition during the converter smelting process, ensuring that materials can accurately and stably enter the converter; a pneumatic purge disk or pipe installed on the end face of the charging port of the charging pipe; the pneumatic purge disk 2 or pipe utilizes the dynamic effect of gas to purge the charging port, effectively removing steel slag and debris adhering to the surrounding of the charging port to prevent clogging; on the pneumatic purge disk or pipe, there are gas ejection holes 2-1 facing the direction of the steel slag, and several gas ejection holes are arranged along the circumferential direction. The setting of the gas ejection holes enables the purge gas to evenly cover the entire end face of the charging port, improving the purge efficiency and ensuring that there are no dead corners for removing steel slag and debris. At the same time, the setting of multiple gas ejection holes also enhances the purge force, helping to more quickly remove the clogging substances; the pneumatic purge disk or pipe is connected to a high-pressure nitrogen gas source through a delivery pipe 2-2, and a gas source control valve 2-3 is installed on the delivery pipe. The high-pressure nitrogen gas source provides a stable and high-pressure gas supply, ensuring that the purge disk or pipe can generate sufficient purge force to effectively remove the clogging substances at the charging port. At the same time, nitrogen, as an inert gas, will not chemically react with steel slag, etc., ensuring the safety and stability of the purge process.

[0017] Further preferably, the center of the gas ejection hole forms an inclination angle of 0-30° with the center line of the charging port. The design of the inclination angle enables the gas ejected from the gas ejection hole to more directly impact the area around the charging port where steel slag is likely to adhere. Due to the certain ejection angle of the gas, it can not only remove the clogging substances on the front of the charging port, but also effectively cover the dead corners at the edge and side of the charging port, thereby comprehensively improving the purge effect. The appropriate inclination angle helps the gas to form a more concentrated jet flow, increasing the impact force on the clogging substances. This concentrated jet flow can more quickly and effectively blow down the steel slag and other debris adhering to the charging port, significantly improving the removal efficiency. The design of the inclination angle also takes into account the influence of gas ejection on the charging pipe and the entire device. By optimizing the ejection angle, the reaction force generated by gas ejection on the charging pipe can be reduced, enhancing the stability and reliability of the equipment. Effective purging can keep the charging port clean, reducing the wear and corrosion of the charging pipe and surrounding components caused by steel slag and other debris. This not only helps to maintain the good operating state of the equipment, but also extends the service life of the equipment.

[0018] Example 2, please refer to Figure 3, a vibrator 3 is installed near the feeding port, and the vibrator is connected to a control switch through a wire. The setting of the vibrator can effectively generate vibrations, helping to loosen and shed the steel slag and sundries adhering to the surrounding of the feeding port, further enhancing the anti-blocking effect. At the same time, the working state of the vibrator can be flexibly controlled through the control switch to achieve vibration on demand, which not only ensures the anti-blocking effect but also avoids unnecessary energy waste. In addition, the installation of the vibrator also helps to improve the smoothness of the feeding port, ensuring that the materials can smoothly enter the converter, thereby improving the smelting efficiency and reducing the risk of production interruption caused by blockage, providing strong support for the continuous and efficient production of the iron and steel smelting industry.

[0019] The vibrator is selected from the model: YZS-10-4 produced by Xinxiang Weili Vibrating Machinery Co., Ltd.:

[0020] Current: 1.65A;

[0021] Vibration frequency: 1450 times / min;

[0022] Power: 0.55KW;

[0023] Voltage: 380V;

[0024] Exciting force: 10KN;

[0025] Further preferably, 2-6 vibrators are arranged along the circumferential direction of the feeding pipe. It can vibrate all-round to loosen the steel slag, improve the anti-blocking efficiency, and at the same time ensure the uniform force of the feeding pipe and enhance the stability.

[0026] In summary, the comprehensive application of this device not only keeps the feeding port clean and smooth, reduces the blockage risk, but also reduces the equipment wear and corrosion and extends the service life. Generally speaking, this anti-blocking device provides continuous and efficient production guarantee for the iron and steel smelting industry, significantly improves the smelting efficiency, reduces the risk of production interruption, and is an important and indispensable device in the smelting process.
