Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment fault diagnosis technology, and in particular to a high-temperature resistant testing instrument chamber. Background Technology

[0002] Converters, molten steel ladles, and molten iron ladles play a crucial role in containing molten metal during high-temperature smelting processes. Their performance and structural condition directly affect the continuity, stability, and safety of the process. In the context of smart steel plant construction, real-time and accurate data collection of the status of these devices is essential for achieving intelligent spraying, intelligent scheduling, improved tank turnover efficiency, and energy conservation.

[0003] The aforementioned equipment consists of a metal shell and a refractory lining, operating for extended periods in extreme thermal environments approaching 1600°C. Due to the combined effects of heat radiation, convection, and conduction, the load-bearing structure is prone to failure, posing a danger. Common failure modes of the load-bearing structure include cracks, weld damage, and structural deformation, while the lining is susceptible to defects such as spalling, erosion, through-cracks, and gaps between blocks. Timely detection of these defects is crucial to preventing major accidents. However, existing testing instruments generally lack high-temperature resistance and must be placed outside the equipment to acquire data remotely and indirectly. Because existing testing instruments cannot withstand high temperatures and must be placed away from heat sources, they are still exposed to intense thermal radiation exceeding 1000°C. This not only makes them susceptible to scorching damage but also makes it difficult to observe lining defects from a near-vertical perspective, leading to data distortion, insufficient ability to identify through-cracks, and large-area blind spots in detection. This severely restricts the accuracy and correctness of repair and operational decisions. Furthermore, the inspection of molten steel and iron ladles relies heavily on manual visual inspection, resulting in low automation and significant safety risks.

[0004] Therefore, existing external inspection methods are insufficient to meet the demands for intelligent and precise inspection. The industry urgently needs a specialized inspection instrument that can directly penetrate the interior of high-temperature cavities under hot conditions, effectively cope with the adverse effects of heat radiation, heat convection, and heat conduction in high-temperature environments, and possess splash-proof and dust-proof capabilities, while also being able to carry multi-modal inspection devices. This would allow for the acquisition of high-quality, low-distortion lining condition data, enabling truly unmanned intelligent inspection. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a high-temperature resistant testing instrument chamber that can solve the technical problem that the existing external testing mode cannot meet the requirements of intelligent and accurate testing.

[0006] This invention provides a high-temperature resistant testing instrument chamber, comprising: a chamber body, a return water pipe fitting, a chamber door, a chamber door opening assembly, a hatch gas seal pipe fitting, an instrument cooling pipe fitting, and a pipe cover assembly; The chamber contains testing instruments and equipment. The chamber's interlayer adopts a water-cooled circulation structure. The internal space of the chamber is flushed with compressed air. The hatch gas seal pipe provides a separate compressed air source to create a slightly positive pressure environment inside the chamber. The return water pipe is used to transport the cooling medium; The hatch and the hatch opening assembly are open during the detection period of the detection instrument and equipment, and closed during non-detection periods. The instrument cooling pipe is used to transmit the protective gas required when the testing instrument is working. The pipe cover assembly is disposed on the outside of the return water pipe fitting and is used to protect the return water pipe fitting.

[0007] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: In this embodiment of the invention, the high-temperature testing instrument chamber can house testing instruments and equipment. Driven by a robotic arm, it can directly enter the interior of converters, molten iron ladles, and molten steel ladles at high temperatures. The chamber door is opened during the testing period of the instruments and equipment and closed during non-testing periods. The robotic arm can scan the interior of smelting equipment such as converters, molten iron ladles, and molten steel ladles along the axis using multi-angle, full-area cross-sectional scanning and spiral scanning modes. This covers areas that are difficult to observe and test using traditional methods, enabling comprehensive collection of process and equipment status information data. This reduces reliance on manual visual inspection, lowers the risk of personnel exposure to high temperatures and hazardous environments, and improves automation and safety levels.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0022] Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts disclosed in this invention.

[0023] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0024] Reference manual attached Figures 1 to 11 The present invention provides a structure for a high-temperature resistant testing instrument chamber, comprising: a chamber body 1, a return water pipe 2, a chamber door 3, a chamber door opening assembly 4, a hatch gas seal pipe 5, an instrument cooling pipe 6, and a pipe cover assembly 7.

[0025] Cabin 1, serving as the main structure for creating a low-temperature microenvironment under external high-temperature conditions, features a circulating cooling chamber structure, multiple cooling gas channels, and various shielding mechanisms and requirements to meet different protection functional needs. Cabin 1 houses detection instruments and equipment, including infrared imaging equipment for temperature detection, ultrasonic and lidar for furnace lining thickness detection, and robotic vision instruments for identifying furnace operating conditions. The interlayer of Cabin 1 employs a water-cooled circulation structure, and the internal space of Cabin 1 is flushed with compressed air. The hatch gas seal pipe 5 provides a separate compressed air source to create a slightly positive pressure environment within Cabin 1, preventing the adverse effects of high-temperature airflow and splashed slag particles on the detection instruments.

[0026] Return water fitting 2 is used to transport cooling medium; The hatch 3 and hatch opening assembly 4 are opened during the detection period of the detection instruments and equipment, and closed during non-detection periods. A dedicated instrument cooling pipe 6 is provided for testing instruments that require internal cooling to transmit the protective gases such as purified compressed air, nitrogen, and argon required when the testing instruments are working. The pipe cover assembly 7 is located on the outside of the return water pipe fitting 2 and is used to protect the return water pipe fitting 2.

[0027] In this embodiment of the invention, the high-temperature testing instrument chamber can house testing instruments and equipment. Driven by a robotic arm, it can directly enter the interior of converters, molten iron ladles, and molten steel ladles at high temperatures. The chamber door is opened during the testing period of the instruments and equipment and closed during non-testing periods. The robotic arm can scan the interior of smelting equipment such as converters, molten iron ladles, and molten steel ladles along the axis using multi-angle, full-area cross-sectional scanning and spiral scanning modes. This covers areas that are difficult to observe and test using traditional methods, enabling comprehensive collection of process and equipment status information data. This reduces reliance on manual visual inspection, lowers the risk of personnel exposure to high temperatures and hazardous environments, and improves automation and safety levels.

[0028] Furthermore, the high-temperature resistant testing instrument chamber possesses comprehensive protection capabilities for itself and the onboard testing instruments under high-temperature conditions. The high-temperature resistant testing chamber is equipped with a circulating cooling chamber structure and cooling gas channels, utilizing channels within the robotic arm to achieve cooling medium transfer. Through the circulation of cooling water and the purging of compressed air or instrument cooling air, nitrogen, and argon, the high-temperature resistant testing instrument chamber protects sensors and electronic components from damage caused by the high-temperature environment.

[0029] Furthermore, the high-temperature resistant testing instrument chamber has protective functions such as automatic opening and closing of the chamber door 3 and air sealing of the chamber opening; the instrument chamber has a slightly positive pressure environment to prevent the adverse effects of high-temperature airflow and splashing particles on the testing instrument.

[0030] Furthermore, the high-temperature resistant testing instrument chamber directly enters the inner cavity of the smelting equipment under high-temperature conditions, and collects process and equipment status information data of the lining in a reasonable position, maximizing the performance of the testing instrument, eliminating the adverse effects of data distortion, and promoting the level of metallurgical equipment fault diagnosis technology.

[0031] Furthermore, the high-temperature resistant testing instrument chamber collects process and equipment status information data within the smelting equipment cavity, improving the accuracy, speed, and efficiency of data collection. This provides a foundation for intelligent scheduling and solves common problems faced by the industry in achieving intelligentization and informatization.

[0032] Furthermore, the high-temperature resistant testing instrument cabin avoids the risks of close-range manual operation, improving the safety level of personnel and equipment; it also avoids the damage to workers caused by heat radiation and high-temperature environments, improving occupational health conditions.

[0033] Furthermore, the high-temperature resistant testing instrument cabin enables precise, unmanned, and information-based testing and maintenance of the linings of smelting equipment such as converters, molten iron ladles, and molten steel ladles, and has high industrial application value.

[0034] The high-temperature testing instrument chamber is mounted at the front end of a water-cooled robotic arm, and the testing instruments are placed within a localized environment created by the protective gas within the water-cooled walls. When the high-temperature testing instrument chamber, along with the robotic arm, penetrates the high-temperature cavities of smelting equipment such as converters, molten steel ladles, and molten iron ladles, the tested instruments, while maintaining their high-temperature resistance, can still operate normally. This allows for multi-angle, full-area testing of the internal cavities of smelting equipment such as converters, molten iron ladles, and molten steel ladles, acquiring undistorted status data.

[0035] In one possible implementation, the cabin 1 includes: an inner wall assembly 11, an outer wall assembly 12, a front wall assembly 13, a rear inner wall assembly 14, and a rear outer wall assembly 15; the front wall assembly 13 has a multi-channel medium passage on its integrated connector 111 for connecting to the front end of the robotic arm and transmitting cooling medium; the inner wall assembly 11, outer wall assembly 12, rear inner wall assembly 14, and rear outer wall assembly 15 form a cooling cavity for cooling medium circulation; a horizontal partition 16 is provided between the inner wall assembly 11 and the outer wall assembly 12; the horizontal partition 16 divides the cooling cavity into an upper cooling cavity and a lower cooling cavity.

[0036] The cooling medium enters the lower cooling chamber through the A1 and A2 channels on the integrated connector 111, and enters the upper cooling chamber through the A3, A4, A5, and A6 holes on the horizontal partition 16. The return water from the upper cooling chamber flows out through the return water pipe 2 into the B1 and B2 channels on the integrated connector 111.

[0037] In this embodiment of the invention, the cabin is designed as a double-layer structure consisting of an inner wall, an outer wall, and front and rear wall components. A horizontal partition is set in the cabin to form two cooling chambers, one above the other. The cooling medium first enters the lower cooling chamber from the A1 and A2 channels of the integrated joint, then flows evenly into the upper cooling chamber through multiple channels on the partition, and finally flows back through the B1 and B2 channels. This dual-chamber series water cooling circulation path can significantly improve cooling efficiency and temperature distribution uniformity, effectively isolate the influence of the external high temperature environment on the sensors inside the cabin, and enhance the structural strength and thermal stability of the cabin, thereby ensuring the reliable operation of the testing instrument under extreme high temperature conditions.

[0038] In one possible implementation, the C1 and C2 channels built into the integrated connector 111 are connected to the instrument cooling pipe 6. The central hole of the integrated connector 111 allows for cable insertion while also providing a cross-sectional gap for compressed air to circulate. The compressed air circulating in the cross-sectional gap serves as the main airflow source for creating a slightly positive pressure environment inside the cabin 1.

[0039] In this embodiment of the invention, by providing dedicated cooling gas to the sensor through the built-in C1 and C2 channels in the integrated connector 111, and by using the remaining cross-sectional gap after the cable is inserted through its central hole to introduce compressed air, space is saved and the airflow is cleverly used as the main source of the micro-positive pressure environment inside the chamber. This effectively prevents high-temperature flue gas, dust and splashed particles from entering the chamber, thereby ensuring normal cooling of the sensor while improving the overall sealing and anti-pollution capability of the chamber, and enhancing the reliability and lifespan of the detection instrument in extreme high-temperature environments.

[0040] In one possible implementation, since the cooling water in the cavity between the inner wall assembly and the outer wall assembly is pressurized, a connecting block 112 is provided between the inner wall assembly 11 and the outer wall assembly 12. The connecting block 112 is welded to the inner wall assembly 11, and a corresponding opening is made on the outer wall assembly 12 for plug welding. This can enhance the cavity's pressure resistance and prevent structural cracking and water leakage.

[0041] In this embodiment of the invention, a connecting block is provided between the inner wall component and the outer wall component, and the structural strength and overall rigidity of the cooling cavity under internal water pressure are effectively enhanced by welding the inner wall and plugging the outer wall opening. This prevents the cavity from deforming, cracking or leaking due to the combined action of thermal stress and water pressure, thereby ensuring the sealing performance and long-term operational reliability of the water cooling system.

[0042] In one possible implementation, due to the need to fix the sensor inside the cavity, a welding block structure 113 is provided at the corresponding position where the detection instrument is fixed between the inner wall assembly 11 and the outer wall assembly 12.

[0043] In this embodiment of the invention, a welding block structure 113 is provided between the inner wall component and the outer wall component at the corresponding sensor installation position. This not only enhances the local structural strength but also allows for flexible arrangement of fixing holes, adapting to the installation requirements of different types or layouts of testing instruments and equipment, and improving the versatility, maintainability, and assembly convenience of the in-cabin sensor configuration.

[0044] In one possible implementation, the hatch frame 131 on the front bulkhead assembly 13 is used to cooperate with the hatch 3 to seal the testing instruments and equipment during non-testing periods; the hatch frame 131 is provided with an air seal annular channel and a sealing strip structure. The inner side of the air seal annular channel is provided with air holes at the top and bottom, and the lower part of the air seal annular channel is provided with an air inlet interface that connects with the hatch air seal pipe 5; when the testing period of the testing instruments and equipment is underway, when the hatch 3 is opened, the outwardly inclined slanted air holes spray out a purge airflow to form an air curtain to protect the testing instruments and equipment.

[0045] In one possible implementation, the hatch 3 and the hatch frame 131 form a movable shielding mechanism. The hatch 3 rotates via a hinge mechanism and is driven by the hatch opening assembly 4. The hatch opening assembly 4 includes: a pull rod 41, a washer 42, a nut 43, a spring support 44, a spring 45, a guide seat 46, a connector 47, a cylinder assembly 48, and a tailstock 49. The pull rod 41 passes through the guide hole sleeve of the cavity and is threadedly connected to the nut 43. One side of the spring support 44 is close to the nut to support the spring 45. The other end of the spring 45, which passes through the pull rod 41, is close to another spring support of the nut 43, transmitting the spring force to the guide seat 46. The guide seat 46 is fixed to the side wall of the hull 1 and allows the pull rod to move back and forth. Therefore, the spring force pushes the hatch 3 to close tightly through the pull rod 41. The connector 47 is threadedly connected to the pull rod 41 and can move with the pull rod 41. The piston rod head of the cylinder assembly 48 is hinged to the connector 47 by a pin; the cylinder assembly 48 and the tailstock 49 are hinged by a pin; when compressed air is introduced into the rod chamber of the cylinder, it drives the pull rod 41 to move, compressing the length of the spring 45, thereby opening the hatch 3.

[0046] It should be noted that, due to the use of a normally closed door driven by a compression spring, the door can be effectively sealed during periods when the sensor is not detecting, and it can also meet the requirements for rapid closure of the door under complex conditions.

[0047] In this embodiment of the invention, the hatch mechanism combines a normally closed spring with a cylinder-driven mechanism to ensure the hatch remains tightly closed during non-detection periods, achieving reliable sealing in conjunction with the air-sealing annular channel and sealing strip on the hatch frame. During detection, compressed air is introduced into the cylinder's rod chamber to push the lever against the spring force and open the hatch. Simultaneously, the oblique air holes in the air-sealing annular channel eject a purge airflow to form a protective air curtain, effectively isolating high temperatures, dust, and molten slag from intrusion. This design not only improves the hatch's sealing performance and anti-contamination capabilities but also achieves automated, rapid-response, and highly reliable hatch opening and closing, ensuring the safe and stable operation of internal sensors under extreme conditions.

[0048] In one possible implementation, the pipe cover assembly serves as a shielding structure, meeting the protective requirements of the external return water pipe 2 and reducing adverse effects such as heat radiation and debris impact. To avoid the connection structure's adverse effect on the cavity's sealing performance, the pipe cover assembly 7 includes a pipe cover 71, an upper base plate 72, and a side base plate 73; after the pipe cover 71, upper base plate 72, and side base plate 73 are threaded together, the upper base plate 72 and side base plate 73 are then welded to the cavity.

[0049] In this embodiment of the invention, by designing the pipe cover assembly as a structure in which the pipe cover, the upper bottom plate and the side bottom plate are first threaded together to form a whole, and then the bottom plate is welded to the cabin, the exposed return water pipes are effectively shielded and protected from high temperature radiation and molten slag collisions. This also avoids directly opening holes or welding complex connecting parts on the sealed cavity wall of the cabin, thereby enhancing the protective performance while maximizing the overall sealing and structural integrity of the cabin.

[0050] In one possible implementation, there is an inclination angle between the integrated joint 111 and the horizontal axis of the inner wall assembly 11. The detection instrument is mounted on a gimbal 8 that can rotate around a horizontal axis, which can meet the requirement of minimizing the angle between the sensor module of the detection device and the normal of the damaged part. Thus, even without joints at points where connections are not needed, good detection data quality can still be obtained by cooperating with the rotation function of the robotic arm. The internal dimensions and height allow the detection instrument to tilt with the cooperation of the gimbal 8. With the cooperation of the robotic arm's rotation around its axis, linear movement, and pitch swing, the detection instrument can achieve various forms of detection and scanning methods.

[0051] In this embodiment of the invention, by designing the horizontal axis of the integrated connector 111 and the inner wall assembly 11 with an inclined angle, and cooperating with the gimbal 8 which can rotate around the horizontal axis, the detection instrument can observe in a direction closer to the normal of the measured surface, significantly improving the data acquisition accuracy. At the same time, sufficient height space is reserved in the cabin to support the sensor to adjust its pitch under the drive of the gimbal, and to coordinate with the rotation, extension and swing of the robotic arm to achieve multi-degree-of-freedom and multi-mode scanning such as spiral and cross-section scanning, without the need to add additional complex joint structures, which simplifies the system design and ensures high coverage and high quality detection capabilities.

[0052] The working principle of the high-temperature resistant testing instrument chamber provided by this invention is described below: The high-temperature resistant testing instrument chamber is mounted on the front end of the robotic arm. The media channels on the integrated connector 111 within the chamber are aligned with the robotic arm. The sealing rings on the media channels of the integrated connector 111 contact the front end face of the robotic arm. With the interface bolts tightened, the high-temperature resistant testing instrument chamber and the robotic arm's media channels are connected, forming a seal with the outside. Cooling water supplied by the robotic arm enters the lower cooling area of ​​the chamber through channels A1 and A2 in the integrated connector 111, and then enters the upper cooling area through holes A3, A4, A5, and A6 on the horizontal partition in the chamber. Return water from the upper cooling area enters the integrated connector through holes B1 and B2 via the return water pipe 2 on the rear wall assembly, and then enters the robotic arm to form a cooling water circulation loop. Cooling air supplied by the robotic arm enters through channels C1 and C2 of the integrated connector, and through the connected instrument cooling pipe 6, meets the cooling requirements of the sensor module inside the testing device. A separate cooling compressed air path passes through the central hole of the integrated connector to the inner side of the air seal ring on the hatch frame 131 of the front wall assembly 13. The center hole of the integrated connector, while accommodating cable insertion, still provides sufficient cross-sectional clearance for compressed air circulation. The compressed air circulating through this clearance serves as the primary airflow source for creating a slightly positive pressure environment within the chamber. When the high-temperature testing instrument chamber is in use, the door is closed; the cooling water circulation channel formed by the A1 and A2 channels and the B1 and B2 channels of the high-temperature testing instrument chamber, along with the robotic arm, maintains continuous circulation; cooling air enters the instrument via the C1 and C2 channels of the integrated connector, entering the delivery mode. When the high-temperature testing instrument chamber is not in the high-temperature environment of a converter, molten iron ladle, or molten steel ladle, or is not in a data acquisition state, the hatch of the high-temperature testing instrument chamber is closed; the cooling water circulation channel formed by the A1 and A2 channels and the B1 and B2 channels, along with the robotic arm, maintains continuous circulation. When the robotic arm, carrying the high-temperature testing instrument chamber, enters the high-temperature environment of a converter, molten iron ladle, or molten steel ladle and is in data acquisition mode, the door is opened; a significant amount of compressed air flows into the slightly positive pressure environment within the chamber through the cable gap in the center hole of the integrated connector. Meanwhile, compressed air for cooling is ejected from the angled air holes on the air-sealed annular channel of the hatch frame to form an air curtain.

[0053] The high-temperature testing instrument chamber's circulating cooling cavity structure, multiple cooling gas channels, and multiple shielding mechanisms create a low-temperature microenvironment within the chamber, effectively meeting the protective requirements of the testing instrument.

[0054] Because the robotic arm can perform individual movements such as rotation, linear movement, and vertical plane swinging, or a combination of several movements; the high-temperature resistant testing instrument chamber is mounted on the robotic arm to collect lining condition data. It is in both the optimal position and low-temperature environment. Relying on the high-temperature resistant testing instrument chamber's own high-temperature resistance performance, it makes up for the weakness of insufficient high-temperature resistance performance of the testing instrument, thereby obtaining lining condition testing information data with minimal distortion.
