Description

Technical Field

[0001] This invention belongs to the field of iron and steel smelting technology, and particularly relates to a converter furnace mouth flame observation device. Background Technology

[0002] In the field of iron and steel smelting, converter steelmaking, as a highly efficient and widely used steelmaking method, relies on the core principle of blowing oxygen into molten iron to trigger a series of vigorous physicochemical reactions, thereby achieving the goals of removing impurities, adjusting composition, and ultimately obtaining qualified molten steel. In this complex and crucial steelmaking process, the state of the converter flame at the furnace mouth acts as a "barometer" of the steelmaking reaction progress, serving as a key basis for operators to accurately judge whether the steelmaking reaction within the furnace is proceeding smoothly and to make a preliminary assessment of the molten steel quality.

[0003] Traditionally, operators rely primarily on visual observation through a glass viewing window in front of the control panel to obtain information about the furnace flame. However, this seemingly simple and direct method of observation harbors numerous serious safety hazards in the actual converter steelmaking production environment. The furnace temperature is extremely high, generating significant amounts of high-temperature radiation, intense light, smoke, and molten steel splashing, among other dangerous situations. Given these risks, the practice of operators directly observing the converter furnace flame through the glass viewing window has been clearly identified as a major safety hazard in the industrial and commercial sectors. This not only poses a direct and serious threat to the personal safety of operators but also hinders the safe, stable, and efficient operation of converter steelmaking production.

[0004] Therefore, this utility model relates to a converter furnace mouth flame observation device. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention provides a converter furnace mouth flame observation device.

[0006] This invention is implemented as follows: a converter furnace mouth flame observation device includes a periscope body, a safety protection box, and a compressed air purging system. The periscope body comprises an objective lens, a reflector group, and an eyepiece forming an optical path transmission system. The objective lens is positioned facing the converter furnace mouth to receive flame light. The reflector group is positioned in the optical path between the objective lens and the eyepiece, changing the light transmission path through multiple reflections, ultimately transmitting the flame image to the eyepiece housed within the safety protection box. The safety protection box has an observation window on its side wall, forming a sealed observation space inside. The eyepiece is fixed inside the observation window. The safety protection box is equipped with a temperature monitoring module and a temperature control execution module. The compressed air purging system includes an air compressor, a purging pipe, and a nozzle assembly. The purging pipe connects to the air compressor and extends to the objective lens mounting position on the periscope body. The nozzle assembly is mounted at the end of the purging pipe and faces the objective lens surface.

[0007] Preferably, the reflector group includes at least two planar reflectors, with the mirror surfaces of adjacent reflectors arranged at a preset angle, so that light forms a zigzag optical path transmission path within the periscope body.

[0008] Preferably, the temperature monitoring module of the safety protection box is a temperature sensor, and the temperature control execution module is a cooling fan. When the temperature sensor detects that the temperature inside the box exceeds a preset threshold, the cooling fan is triggered to start.

[0009] Preferably, the observation window is made of high-strength, high-temperature resistant transparent quartz glass, and a sealed connection structure is provided between the observation window and the safety protection box body.

[0010] Preferably, the purging pipe is equipped with a flow regulating device, which is a flow regulating valve used to control the output pressure and flow parameters of compressed air.

[0011] Preferably, the safety protection box is provided with support feet at the bottom.

[0012] The advantages and technical effects of this invention are as follows: This invention, utilizing a unique periscope principle, ingeniously and accurately transmits the flame image from the converter furnace mouth to a safety protection box, providing operators with a safe observation platform. This eliminates the need for direct exposure to hazardous environments, greatly ensuring personnel safety. The safety protection box acts as a "robust shield" for the device, forming a sealed space that effectively isolates it from harsh external environments and protects internal components from high temperatures, dust, and other harmful substances. The temperature monitoring module and temperature control execution module work together to regulate the temperature inside the box in real time, ensuring stable operation of the device. The compressed air purging system acts as a "cleaning guardian," precisely controlling the flow rate to promptly remove impurities from the objective lens surface, ensuring a clear optical path and improving image quality. Furthermore, the use of quartz glass for the observation window and the sealed connection structure further enhances the device's sealing and durability; the adjustable telescopic support feet improve installation flexibility and accuracy. These carefully designed auxiliary devices work together to comprehensively improve the stability, reliability, and practicality of the observation device, providing a safe, efficient, and reliable solution for flame observation during converter steelmaking, and powerfully promoting the smooth progress of steelmaking production.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0016] Please see Figure 1 A converter furnace mouth flame observation device includes a periscope body, a safety protection box, and a compressed air purging system. The periscope body consists of an objective lens 2, a reflector group 3, and an eyepiece 4, forming an optical path transmission system that clearly transmits the converter furnace mouth flame image to the eyepiece inside the safety protection box. This allows operators to safely and intuitively observe the flame situation, providing accurate information for converter operation and helping to improve production efficiency and product quality. The objective lens is positioned directly opposite the converter furnace mouth to receive flame light. The reflector group is positioned in the optical path between the objective lens and the eyepiece, changing the light transmission path through multiple reflections, ultimately transmitting the flame image to the eyepiece inside the safety protection box. The safety protection box has an observation window on its side wall and forms a sealed observation space inside. The eyepiece is fixed to the observation... Inside window 6, the safety protection box is equipped with a temperature monitoring module and a temperature control execution module; it can monitor and regulate the temperature inside the box in real time, effectively protecting internal components such as eyepieces, avoiding high-temperature damage, extending the service life of the device, and reducing maintenance costs; the compressed air purging system includes an air compressor 7, a purging pipe 8, and a nozzle assembly 8. The purging pipe is connected to the air compressor and extends to the periscope main objective lens mounting position. The nozzle assembly is installed at the end of the purging pipe and faces the objective lens surface, which can purge the surface of the periscope main objective lens, promptly removing dust, impurities, etc. attached to the objective lens, ensuring the cleanliness of the objective lens, ensuring the clarity and stability of the optical path transmission, further improving the accuracy and reliability of flame observation, and providing a strong guarantee for the safe and stable operation of converter production.

[0017] Preferably, the reflector group includes at least two planar reflectors, with the mirror surfaces of adjacent reflectors arranged at a preset angle, creating a zigzag optical path transmission path for light within the periscope body. A preferred angle of 45 degrees enables efficient light transmission within a limited structure, accurately conveying the flame image to the eyepiece. Simultaneously, the zigzag optical path avoids potential interference factors, reduces light loss and distortion during transmission, improves image quality, and allows operators to observe the converter furnace flame condition more clearly and accurately, thus aiding production operations.

[0018] Preferably, the temperature monitoring module of the safety protection box is a temperature sensor 10, and the temperature control execution module is a cooling fan 11. When the temperature sensor detects that the temperature inside the box exceeds a preset threshold, it triggers the cooling fan to start. The temperature sensor, as the temperature monitoring module, can accurately sense the temperature inside the safety protection box in real time. When the temperature exceeds the preset threshold, the cooling fan, as the temperature control execution module, starts promptly to quickly reduce the temperature inside the box. This combination effectively protects components such as the eyepiece inside the box, preventing damage from high temperatures, extending the service life of the device, reducing downtime for maintenance due to component damage, and ensuring the continuity and stability of converter flame observation.

[0019] Preferably, the observation window is made of high-strength, high-temperature resistant transparent quartz glass, and a sealed connection structure is provided between the observation window and the safety protection box. This allows it to withstand the high-temperature environment surrounding the converter, ensuring clear observation even at high temperatures. Simultaneously, the sealed connection structure prevents external dust and impurities from entering the safety protection box, maintaining a clean environment inside, avoiding contamination of the eyepiece, and ensuring the clarity and accuracy of the observed images.

[0020] Preferably, the purging pipe is equipped with a flow regulating device, namely a flow regulating valve 12, used to control the output pressure and flow parameters of compressed air. Through proper adjustment, effective purging of the periscope's objective lens surface can be ensured, removing dust and impurities, while avoiding damage to the objective lens due to excessive compressed air pressure or flow. Furthermore, flexible parameter adjustment according to actual operating conditions can optimize the purging effect and improve the stability and reliability of the device operation.

[0021] Preferably, the bottom of the safety protection box is equipped with support feet 13, such as telescopic support feet with a spiral structure. By adjusting the support feet, the objective lens 2 can accurately receive the light from the furnace mouth flame. This design improves the flexibility and adaptability of the device installation, can cope with different installation environments, ensures that the objective lens and the converter mouth maintain the optimal relative position, and ensures that the flame light can smoothly enter the periscope body, thereby obtaining a clear and accurate flame image and improving the accuracy of converter flame observation.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
