Description

Technical Field

[0001] This utility model relates to the field of online detection of high-temperature melt composition in the ironmaking industry, specifically to a high-durability vibration-resistant device for an online detection probe of high-temperature melt composition in ironmaking. Background Technology

[0002] In recent years, with the continuous advancement of ironmaking technology, the requirements for the accuracy and stability of online detection of high-temperature melt composition have been increasing. However, existing detection technologies still face many challenges when dealing with complex industrial environments such as high temperature, extreme cold, high dust, and strong vibration. In particular, vibration has a significant impact on the online detection of high-temperature melt composition in ironmaking: it not only causes frequent and minute changes in the position of the laser beam relative to the melt surface, introducing noise that reduces the signal-to-noise ratio of the spectral signal and causing spectral peak drift, making it difficult to identify characteristic spectral lines and thus affecting the accuracy of element quantification, but also reduces the accuracy and repeatability of the detection results, making it possible for the same melt to produce significantly different results even after multiple detections. In addition, long-term vibration can accelerate the wear of internal components of the probe, leading to accelerated equipment aging and potentially causing internal connecting wires to loosen or fall off, affecting signal transmission and the stable operation of the equipment.

[0003] It is evident that vibration has become a key factor affecting the accuracy of detection and the lifespan of equipment. Therefore, developing a new type of vibration-damping device that can effectively resist all-around vibration and ensure the long-term stable operation of detection probes is of great significance for improving the quality control of products in the ironmaking industry. Utility Model Content

[0004] This invention proposes a high-durability vibration-proof device for an online detection probe of the composition of high-temperature molten iron in ironmaking, which solves the problem of stable operation of the detection probe under complex working conditions and reduces the equipment failure rate in related technologies.

[0005] The technical solution of this utility model is as follows:

[0006] This utility model is a high-durability vibration-damping device for an online detection probe of high-temperature melt composition in ironmaking, comprising: a probe, a side plate fixedly connected to the side of the probe, and a vibration damping device provided on the side of the probe;

[0007] The vibration damping device includes a microporous foam layer, the side of which is fixedly connected to the side of the probe. A spring steel sheet layer is fixedly connected to the top of the microporous foam layer. A rubber layer is fixedly connected to the top of the spring steel sheet layer. A mounting bracket is fixedly connected to the top of the rubber layer. A support is rotatably connected to the side of the mounting bracket. A pitch adjustment bolt is bolted to the side of the support. A connecting plate is fixedly connected to the bottom of the support. A mounting base is fixedly connected to the bottom of the connecting plate.

[0008] Optionally, a communication module is fixedly connected to the bottom of the mounting bracket, and a communication interface is fixedly connected to the bottom of the communication module. A protective box is fixedly connected to the side of the side plate. The communication module and the communication interface enable the transmission of detection data to meet the dynamic control requirements of the steelmaking process. The protective box can isolate the components inside the side plate from the corrosion of high-temperature flue gas and dust.

[0009] Optionally, the mounting base has mounting holes on its top, and the number of brackets is set to two, symmetrically arranged along the vertical central axis of the mounting frame. The mounting holes on the mounting base facilitate quick fixing of the device to the steelmaking equipment, and the two symmetrically distributed brackets ensure that the vibration damping device is subjected to balanced forces, avoiding structural deformation caused by excessive vibration on one side.

[0010] Optionally, a detector is fixedly connected to the inner surface of the side panel, and a high-temperature light transmittance sensor is fixedly connected to the inner wall of the side panel. The detector is directly integrated inside the side panel, shortening the transmission distance of the detection optical path. The high-temperature light transmittance sensor monitors the light transmittance of the high-temperature resistant lens on the side of the side panel in real time, providing a precise triggering basis for subsequent cleaning actions.

[0011] Optionally, a high-temperature adaptive lens cleaning device is provided on the side of the side plate. The high-temperature adaptive lens cleaning device includes a high-temperature resistant motor. The side of the high-temperature resistant motor is fixedly connected to the inner wall of the protective box. The output shaft of the high-temperature resistant motor is fixedly connected to a rotating shaft. The end of the rotating shaft away from the high-temperature resistant motor is fixedly connected to a mounting block. The side of the mounting block is fixedly connected to a connecting block. The end of the connecting block away from the mounting block is fixedly connected to a high-temperature resistant scraper.

[0012] Optionally, the bottom of the high-temperature resistant scraper is fixedly connected to a plurality of perforated nozzles, which are distributed in a linear array at the bottom of the high-temperature resistant scraper. The linearly arrayed perforated nozzles can spray out a uniform air curtain, which blows away loose impurities while the high-temperature resistant scraper removes contaminants. The air curtain can also prevent molten material from splashing directly onto the lens, thereby reducing the lens contamination rate.

[0013] Optionally, an argon gas supply box is fixedly connected to the side of the protective box. A high-temperature resistant pipeline runs through the side of the argon gas supply box, and one end of the high-temperature resistant pipeline is connected to a multi-hole nozzle. The argon gas supply box provides inert gas, which is delivered to the multi-hole nozzle through the high-temperature resistant pipeline to prevent the lens from oxidizing at high temperatures. The high-temperature resistant pipeline is adapted to high-temperature environments, ensuring stable gas delivery, eliminating the risk of high-temperature embrittlement, ensuring the continuous effectiveness of the cleaning gas curtain, and reducing cleaning failures caused by gas supply interruptions.

[0014] Optionally, a signal receiver is fixedly connected to the top of the probe, and the side of the high-temperature resistant scraper is located on the displacement trajectory of the high-temperature resistant lens on the side plate. The signal receiver efficiently collects detection signals, further ensuring the accuracy of component analysis. The displacement trajectory of the high-temperature resistant scraper is adapted to the lens, allowing it to conform to the lens surface for cleaning. Simultaneously, multiple nozzles spray air synchronously, achieving coordinated cleaning through scraping and air spraying.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] 1. The vibration damping device in this utility model can effectively reduce vibration, reduce the interference of vibration on the detection process, improve the signal-to-noise ratio of the spectral signal and the accuracy of characteristic spectral line identification. The omnidirectional vibration damping design ensures the stable operation of the detection probe under complex working conditions, reduces the equipment failure rate, and the combination of multiple materials distributes the vibration damping load, reduces the wear and aging of internal components, and significantly extends the service life of the equipment. Due to the improved stability and durability of the equipment, the frequency of maintenance and replacement of parts is reduced, and the overall maintenance cost is reduced.

[0017] 2. In this utility model, the high-temperature adaptive lens cleaning device uses a high-temperature motor to drive the rotating shaft to rotate the high-temperature scraper. The scraper adheres to the lens surface to scrape off sintered contaminants, avoiding the problem of sudden drop in light transmittance and attenuation of detection signal caused by such stubborn contaminants. In conjunction with the argon gas curtain sprayed from the multi-hole nozzle, the loose impurities scraped off by the scraper can be blown away simultaneously, avoiding secondary adhesion of impurities.

[0029] Example 1

[0030] Reference Figures 1-5 The first embodiment of this utility model proposes a high-durability vibration-damping device for an online detection probe of the composition of high-temperature melt in ironmaking, comprising: a probe 1, a side plate 3 fixedly connected to the side of the probe 1, and a vibration damping device 5 provided on the side of the probe 1;

[0031] The vibration damping device 5 includes a microporous foam layer 51, the side of which is fixedly connected to the side of the probe 1. A spring steel sheet layer 52 is fixedly connected to the top of the microporous foam layer 51. A rubber layer 53 is fixedly connected to the top of the spring steel sheet layer 52. A mounting bracket 54 is fixedly connected to the top of the rubber layer 53. A bracket 56 is rotatably connected to the side of the mounting bracket 54. A pitch adjustment bolt 55 is bolted to the side of the bracket 56. A connecting plate 57 is fixedly connected to the bottom of the bracket 56. A mounting base 58 is fixedly connected to the bottom of the connecting plate 57.

[0032] A communication module 59 is fixedly connected to the bottom of the mounting bracket 54, and a communication interface 510 is fixedly connected to the bottom of the communication module 59. A protective box 4 is fixedly connected to the side of the side plate 3. The communication module 59 and the communication interface 510 realize the transmission of detection data to meet the dynamic control requirements of the steelmaking process. The protective box 4 can isolate the components inside the side plate 3 from the corrosion of high-temperature flue gas and dust.

[0033] The mounting base 58 has mounting holes at its top, and two brackets 56 are provided, symmetrically arranged along the vertical central axis of the mounting frame 54. The mounting holes of the mounting base 58 facilitate quick fixing of the device to the steelmaking equipment, and the two symmetrically distributed brackets 56 ensure that the vibration damping device 5 is subjected to balanced forces, avoiding structural deformation caused by excessive vibration on one side.

[0034] A detector 10 is fixedly connected to the inner side of the side panel 3, and a high-temperature light transmittance sensor 9 is fixedly connected to the inner wall of the side panel 3. The detector 10 is directly integrated inside the side panel 3, shortening the transmission distance of the detection optical path. The high-temperature light transmittance sensor 9 monitors the light transmittance of the high-temperature resistant lens on the side of the side panel 3 in real time, providing a precise triggering basis for subsequent cleaning actions.

[0035] In this embodiment, when the online detection probe 1 for the high-temperature melt composition of ironmaking enters the working state, the device is first fixed to the steel structure of the ironmaking equipment, such as the sintering or blast furnace site, through the mounting holes of the mounting base 58. At this time, the vibration damping device 5 is synchronously placed in the vibration environment of the ironmaking working condition along with the probe 1. After the operation starts, the external vibration is first transmitted to the connecting plate 57 through the mounting base 58, and then transmitted to the support 56 by the connecting plate 57. Subsequently, the vibration energy is further transmitted to the mounting frame 54, which is rotatably connected to the support 56, and finally acts on the microporous foam layer 51 through the rubber layer 53 and the spring steel sheet layer 52 at the bottom of the mounting frame 54. At this time, the microporous foam layer 51, which is directly attached to the side of the probe 1, takes effect first: the microporous foam layer 51 is about 15mm thick and has a total thickness of 40mm. Its internal porous structure undergoes elastic deformation under the action of vibration stress. The microporous foam layer 51 absorbs vibration amplitude through deformation by squeezing the pore walls and air damping. In particular, for low-frequency impact vibrations generated by on-site material conveying systems, the microporous foam layer 51 can absorb vibration amplitude through deformation. After the initial vibration reduction by the microporous foam layer 51, the medium-frequency vibrations that are not completely dissipated continue to be transmitted upward to the spring steel sheet layer 52. When the vibration stress is applied to the steel sheet, the steel sheet undergoes bending deformation. Through elastic deformation, the vibration energy is converted into elastic potential energy. Then, through the deformation recovery process, some of the energy is released in the form of a small amount of heat, thus achieving secondary buffering of medium-frequency vibrations. The remaining high-frequency vibration and minor impact energy are transmitted to the top rubber layer 53 through the spring steel sheet layer 52. The rubber layer 53 utilizes the high damping properties of the polymer material to dissipate high-frequency vibration energy through intermolecular friction and chain segment movement under vibration. High-frequency vibration causes relative sliding of the rubber molecular chains; the internal frictional resistance during this sliding process converts vibration energy into heat energy, which is slowly released, effectively suppressing the transmission of high-frequency noise to the mounting frame 54 and probe 1. Throughout the vibration reduction process, the pitch adjustment bolts 55 on the side of the bracket 56 consistently play a role in structural stability. The bolt ends abut against the side of the mounting frame 54, and the relative angle between the mounting frame 54 and the bracket 56 can be adjusted by pre-tightening force, ensuring that the probe 1 maintains the required pitch posture for detection in the vibration environment. Simultaneously, the two brackets 56 symmetrically distributed along the vertical central axis of the mounting frame 54 can evenly distribute vibration stress to the connecting plate 57 and the mounting base 58, preventing deformation or breakage of the bracket 56 due to unilateral vibration overload, further improving the overall structural durability of the vibration reduction device 5.

[0036] Example 2

[0037] Reference Figures 1-5This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a high-temperature adaptive lens cleaning device 6 is provided on the side of the side plate 3. The high-temperature adaptive lens cleaning device 6 includes a high-temperature resistant motor 61. The side of the high-temperature resistant motor 61 is fixedly connected to the inner side wall of the protective box 4. The output shaft of the high-temperature resistant motor 61 is fixedly connected to a rotating shaft 62. The end of the rotating shaft 62 away from the high-temperature resistant motor 61 is fixedly connected to a mounting block 63. The side of the mounting block 63 is fixedly connected to a connecting block 64. The end of the connecting block 64 away from the mounting block 63 is fixedly connected to a high-temperature resistant scraper 66.

[0038] The bottom of the high-temperature resistant scraper 66 is fixedly connected to a multi-hole nozzle 67. The number of multi-hole nozzles 67 is set to several and distributed in a linear array at the bottom of the high-temperature resistant scraper 66. The linearly arrayed multi-hole nozzles 67 can spray out a uniform air curtain, which blows away loose impurities while the high-temperature resistant scraper 66 scrapes away contaminants. The air curtain can also prevent molten metal from splashing directly onto the lens, thereby reducing the lens contamination rate.

[0039] An argon supply box 7 is fixedly connected to the side of the protective box 4. A high-temperature resistant pipe 8 runs through the side of the argon supply box 7, and one end of the high-temperature resistant pipe 8 is connected to the multi-hole nozzle 67. The argon supply box 7 provides inert gas, which is delivered to the multi-hole nozzle 67 through the high-temperature resistant pipe 8 to prevent the lens from oxidizing at high temperatures. The high-temperature resistant pipe 8 is adapted to high-temperature environments, ensuring stable gas delivery without the risk of high-temperature embrittlement, ensuring the continuous effectiveness of the cleaning gas curtain, and reducing cleaning failures caused by gas supply interruptions.

[0040] A signal receiver 2 is fixedly connected to the top of the probe 1, and the side of the high-temperature resistant scraper 66 is located on the displacement trajectory of the high-temperature resistant lens on the side of the side plate 3. The signal receiver 2 efficiently collects detection signals to further ensure the accuracy of component analysis. The displacement trajectory of the high-temperature resistant scraper 66 is adapted to the lens, allowing it to conform to the lens surface to complete cleaning. At the same time, the multi-hole nozzle 67 sprays air synchronously, achieving coordinated cleaning of scraping and air spraying.

[0041] Compared to Example 1, the high-temperature motor 61 is further de-energized and stops rotating, causing the high-temperature scraper 66 to remain in the initial avoidance position, i.e., the scraper is away from the lens surface, avoiding obstruction of the detection light path. No gas is emitted from the multi-hole nozzle 67, the argon supply box 7 is in a low-pressure holding state, there is no airflow in the high-temperature pipeline 8, and contamination monitoring is activated: the high-temperature light transmittance sensor 9 on the inner wall of the side plate 3 collects lens transmittance data in real time. The sensor's emitting end projects a detection light of a specific wavelength onto the lens, and the receiving end captures the light intensity penetrating the lens, calculating the transmittance through the light intensity attenuation rate. The high-temperature motor 61 is energized and starts, its output shaft driving the rotating shaft 62 to rotate clockwise or counterclockwise, with a preset unidirectional rotation to avoid cable entanglement. The end of the rotating shaft 62 away from the motor is fixedly connected to the mounting block 63, which drives the high-temperature scraper 66 to rotate synchronously via the connecting block 64. The scraper is made of ceramic-reinforced alloy, and its movement trajectory has been preset and calibrated to ensure that the scraper edge is in close contact with the lens surface during rotation. The scraper rotates with the rotating shaft 62, removing stubborn contaminants from the lens surface through physical scraping. During the scraping process, the rounded chamfer design of the scraper edge prevents sharp edges from scratching the lens, while pushing the scraped impurities to the outside of the lens to prevent accumulation. Synchronously with the motor start-up, the solenoid valve of the argon supply box 7 opens, and the argon gas in the box is delivered to the interior of the protective box 4 through the high-temperature resistant pipeline 8. After being buffered by the high-temperature resistant corrugated hose at the end of the high-temperature resistant pipeline 8, the argon gas flows into the multi-hole nozzle 67. The nozzles are distributed in a linear array along the bottom of the high-temperature resistant scraper 66, and the multi-hole nozzle 67 is oriented at an angle to the lens surface, ensuring that the sprayed argon gas forms a fan-shaped gas curtain, blowing the loose impurities scraped off by the scraper away from the lens area, preventing the impurities from re-attaching, and also forming an inert gas protective film on the lens surface to prevent molten splashes or high-temperature fumes from directly contacting the lens during the cleaning process, while also preventing the lens from being oxidized at high temperatures.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
