Description

Technical Field

[0001] The present invention belongs to the technical field of fire extinguishing systems, and particularly relates to a mobile intelligent fire extinguishing system for the extraction section of hydrometallurgy with wet process. Background Technique

[0002] Hydrometallurgy, as an independent technology, is a metallurgical technology that developed rapidly during World War II. Since some minerals such as uranium cannot be extracted by traditional pyrometallurgy and can only be separated and purified in chemical solutions, this method of extracting metals is hydrometallurgy. In recent decades, with the development of the rare earth and non-ferrous metal industries, people's requirements for the purity and precise ratio of materials have become higher and higher. The separation technology of similar metals has developed very rapidly. In particular, the use of extraction separation technology can make the purity of metals higher and the ratio of alloy materials more precise, thus producing more excellent new materials, such as corrosion-resistant and high-temperature-resistant alloys, cathode materials for power batteries, etc. However, a large amount of organic extractants and solvent kerosene are used in the extraction and separation process of hydrometallurgy. In the currently popular tank continuous extraction process, the tank storage capacity of organic extractants in a workshop is generally several hundred cubic meters or even more than a thousand cubic meters. Moreover, these extraction tanks are generally composed of PVC plates welded on site. Once a fire gets out of control, the PVC quickly softens and breaks, and hundreds or thousands of cubic meters of organic phase (oil phase) float on thousands of cubic meters of water phase, becoming a flowing fire source spreading everywhere. Such a fire is often devastating to the entire extraction line and will also cause catastrophic heavy metal pollution. In the past two decades, with the rapid development of domestic hydrometallurgy, especially after the extraction and separation technology has been adopted in industries such as non-ferrous metals and rare earths, many extraction lines have been built in China successively. Some single-line construction areas have reached the limit required by the Class C workshop specifications, which also means that the fire hazards are increasing, and the scale and impact of fires are also getting larger. In the past decade, there have been three major such fires reported in China, and the loss of each fire has exceeded 100 million yuan. Therefore, how to prevent and extinguish fires scientifically has become an issue that scientific and technological workers in the fields of hydrometallurgy and related design and fire protection have to pay attention to.

[0003] Regarding the fire prevention issues in the extraction section, design units and construction units generally only design, construct, and manage in accordance with the design specifications for Class C factories. They do not truly study the possible causes of fire in the entire Extraction Workshop A, the early warning of potential hazards, the consequences of fires of different scales, and the disposal measures at different stages from early warning to fire. Nor do they have a feasible plan. This is also the reason for the heavy losses caused by the fires that have occurred in the extraction line so far. Chinese Patent No. 202221836621.X discloses an extraction line fire prevention system taking a copper extraction production line as an example, including fire detectors, a fire alarm controller, a foam fire protection system, and a fire separation water curtain system. The design concept of this system is very good and can meet the copper extraction line, but it has obvious defects for extraction lines using polyvinyl chloride extraction tanks for other non-ferrous metals such as nickel-cobalt separation and rare earth separation. First, the fire early warning is lagging. Although the patent is equipped with fire detection, in production practice, once the fire characteristics such as flames and smoke appear, it may be too late. Early warning of potential hazards should be made according to the on-site working conditions, that is, potential hazards must be warned in advance. Second, there is no classification of fire levels according to the scale of the fire and corresponding fire extinguishing measures are not adopted. Under normal circumstances, fires in the extraction line are caused by motor failures in the mixing chamber (or pipeline mixer). In the initial stage of the fire, there is only a fire in the mixing chamber area, and this is also the stage when it is easiest to control and extinguish the fire. Third, the patent sets fixed fire shutters above each extraction tank fire prevention partition area, resulting in a large capital investment. Fourth, there are design defects in the foam fire protection system. For extraction lines such as nickel-cobalt separation and rare earth separation, it is best not to use foam for fire extinguishing. The main reason is that the organic phase of the extractant is above the aqueous phase in the extraction tank. When a large amount of foam enters the tank and causes overflow, the first to escape is the organic phase. The burning organic phase flowing and spreading in the workshop not only cannot effectively extinguish the fire but may also make the fire range larger and even get out of control. In a domestic company, the burning organic phase of a similar fire spread along the workshop floor drain and even caused a fire in the adjacent workshop. In addition, the foam fire extinguishing agent will introduce other impurities and pollute the materials, which is not conducive to the recovery and disposal of materials after the fire. Fourth, the prevention of environmental disasters after the fire is not considered. For non-ferrous metal separation enterprises, once overflow occurs, the aqueous phase and organic phase containing a large amount of heavy metals polluting the environment will become a very serious secondary disaster, and the losses of the secondary disaster are also relatively large.

[0004] Through the analysis of the reported technologies, these methods in the prior art still only stay at the basic fire prevention and extinguishing concepts. To be truly applied to production practice, improvements and perfection need to be made according to the defects mentioned above. Summary of the Invention

[0028] The following will make a specific and detailed description of the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0029] In combination with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an intelligent fire extinguishing system for a mobile hydrometallurgical extraction section involves Extraction Workshop A. Inside Extraction Workshop A, there is a hydrometallurgical extraction line 1, including a suspended track 2 erected above the hydrometallurgical extraction line 1. On the hydrometallurgical extraction line 1, there are a robot automatic inspection system 3 for fire hazards, an automatic fire hazard and fire disposal system 4, and a pollutant collection system 5 during the fire disposal process. The robot automatic inspection system 3 for fire hazards is used to conduct 360° infrared camera inspections on the area of the hydrometallurgical extraction line 1. The automatic fire hazard and fire disposal system 4 is used to carry out fire extinguishing and isolation treatment on the area where a fire occurs. The pollutant collection system 5 during the fire disposal process is used to collect the wastewater and materials generated after fire extinguishing.

[0030] The present invention proposes an advanced intelligent fire extinguishing system for a mobile hydrometallurgical extraction section to ensure safe and efficient operation during the hydrometallurgical production process.

[0031] In order to achieve all-round and dead-angle-free monitoring of the extraction line inside Extraction Workshop A, a suspended track 2 is erected above the hydrometallurgical extraction line 1. This suspended track 2 is not only stable and reliable but also provides a flexible operation path for subsequent automated inspection and disposal equipment.

[0032] Running along the suspended track 2 is the robot automatic inspection system 3 for fire hazards. The robot automatic inspection system 3 for fire hazards is equipped with a high-precision 360° infrared camera device, which can capture and analyze the temperature changes in every corner of the extraction line in real time, effectively identifying potential fire hazard points. Once abnormal temperature rise or fire signs are detected, the system immediately activates the alarm mechanism and quickly feeds back the information to the control center.

[0033] Immediately afterwards, the automatic fire hazard and fire disposal system 4 responds quickly. The automatic fire hazard and fire disposal system 4 integrates advanced fire source positioning technology and efficient fire extinguishing devices, which can accurately locate the area where a fire occurs in the shortest time and automatically spray fire extinguishing agents for fire extinguishing. At the same time, to prevent the spread of fire, the automatic fire hazard and fire disposal system 4 can also automatically activate the isolation device to effectively isolate the fire area from other parts of the production line, ensuring that other parts of the production line are not endangered.

[0034] During the fire extinguishing process, the pollutant collection system 5 during the fire disposal process can efficiently collect the wastewater and materials generated after fire extinguishing, preventing them from causing secondary pollution to the environment. The collected wastewater and materials are then sent to special treatment facilities for harmless treatment or recycling, achieving the maximum utilization of resources and the minimum impact on the environment.

[0035] This mobile hydrometallurgical extraction section intelligent fire extinguishing system provides comprehensive safety protection for hydrometallurgical production by integrating advanced technologies such as automated inspection, rapid-response fire extinguishing, and efficient pollutant collection. It not only improves the safety and stability of the production line but also effectively reduces the risk of environmental pollution.

[0036] Combined with Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, the automatic inspection system for fire hazards robots 3 includes an inspection robot 6 moving on a suspended track 2. The inspection robot 6 can move stably and precisely along the suspended track 2 in a complex industrial environment. The main structure of the robot is strong and durable, capable of adapting to the unique high-temperature, humid, and potentially corrosive environment of a metallurgical factory.

[0037] The inspection robot 6 is equipped with a 360° infrared camera inspection and temperature measurement system. The 360° infrared camera inspection and temperature measurement system integrates a high-resolution infrared camera and advanced thermal imaging technology. It can capture infrared images of the surrounding environment of the extraction line in real time and analyze these images through complex algorithms to accurately measure the temperature at each monitoring point. The 360° infrared camera inspection and temperature measurement system can detect and warn of potential fire hazards in a timely manner, such as local overheating or abnormal temperature rise areas, thus greatly advancing the time window for fire prevention.

[0038] To ensure efficient information flow and immediate response, the inspection robot 6 establishes a wireless communication connection with the fire hazard and automatic fire disposal system 4. The latest wireless communication technology is adopted to ensure high-speed data transmission and low-latency response. Once the inspection robot 6 detects an abnormality through the infrared camera inspection and temperature measurement system, it will immediately send alarm information, the abnormal location, and the preliminary judgment result to the fire hazard and automatic fire disposal system 4 via a wireless signal. After receiving this information, the fire hazard and automatic fire disposal system 4 can quickly respond, activate the corresponding fire extinguishing and isolation procedures, and effectively contain the further development of the fire.

[0039] Combined with Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, the inspection robot 6 includes an inspection robot slider 61 set on the suspended track 2. The inspection robot slider 61 is the direct connection part between the robot and the suspended track 2. The inspection robot slider 61 ensures the structural stability and durability during long-term and high-frequency movement. The inspection robot slider 61 also integrates a precision guiding and driving mechanism, enabling the inspection robot 6 to move smoothly and accurately along the track and maintain a stable running trajectory even in the face of complex terrains such as curved or inclined tracks.

[0040] The inspection robot slider 61 is provided with an inspection robot probe 62. The inspection robot probe 62 is the "eyes" and "brain" of the inspection robot 6, integrating a variety of sensors and data processing units. Among them, the 360° infrared camera inspection and temperature measurement system is the core part of the probe. It can capture the infrared images of the surrounding environment of the hydrometallurgical extraction line 1 in real time and analyze these images through complex algorithms to accurately measure the temperatures of each monitoring point. The inspection robot probe 62 may also be equipped with other monitoring devices such as visible light cameras and gas sensors to achieve all-round and multi-parameter monitoring of the environment of the hydrometallurgical extraction line 1.

[0041] The inspection robot probe 62 is not only responsible for data collection but also undertakes the important task of wireless communication with the fire hazard and automatic fire disposal system 4. Through the built-in wireless communication module, the inspection robot probe 62 can transmit the collected data to the fire hazard and automatic fire disposal system 4 in real time for further analysis and processing. At the same time, it can also receive the instructions sent by the fire hazard and automatic fire disposal system 4, such as adjusting the inspection route and starting specific monitoring devices, so as to achieve remote control and intelligent management.

[0042] Combined with Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 9 As shown, the fire hazard and automatic fire disposal system 4 includes a fire extinguishing robot 7 and an isolation and fire extinguishing device 8 that move side by side on the suspended track 2. The fire extinguishing robot 7 and the isolation and fire extinguishing device 8 establish a wireless communication connection with the fire hazard robot automatic inspection system 3.

[0043] Specifically, the fire hazard and automatic fire disposal system 4 can quickly and accurately respond to fire hazards and effectively carry out fire extinguishing and isolation treatment, thus minimizing the damage to the production line and environmental pollution caused by fires. It is mainly composed of a fire extinguishing robot 7 and an isolation and fire extinguishing device 8 that move flexibly side by side on the suspended track 2. The two work together to jointly form a powerful fire emergency disposal system.

[0044] The fire extinguishing robot 7, as the "vanguard" of the fire hazard and automatic fire disposal system 4, is equipped with advanced fire extinguishing equipment and intelligent control systems. It can quickly locate the fire occurrence point based on the fire information provided by the fire hazard robot automatic inspection system 3 and initiate the corresponding fire extinguishing procedures. The fire extinguishing robot 7 is equipped with carbon dioxide fire extinguishing agent, which will not pollute the extraction line. Fighting side by side with the fire extinguishing robot 7 is the isolation fire extinguishing device 8. The main task of the isolation fire extinguishing device 8 is to prevent the spread of fire, effectively isolate the fire area from other parts of the production line, and at the same time release steam for fire extinguishing, which will also not pollute the extraction line. The isolation fire extinguishing device 8 consists of an automatically lifted isolation board, a water curtain system, a steam fire extinguishing system, etc. Once it receives the fire information, the isolation fire extinguishing device 8 will be immediately activated, quickly forming a solid barrier around the fire area, effectively containing the spread of the fire and automatically extinguishing the fire.

[0045] Not only do the fire extinguishing robot 7 and the isolation fire extinguishing device 8 each possess powerful functions, but also a stable and reliable wireless communication connection has been established among them and with the fire hazard robot automatic inspection system 3. This ensures the real-time transmission of information and the immediate execution of instructions. When the inspection robot 6 discovers a fire hazard or a fire, the inspection robot 6 will immediately send the relevant information to the fire hazard and automatic fire disposal system 4. After receiving this information, the fire hazard and automatic fire disposal system 4 will quickly analyze and make a decision, and then send specific action instructions to the fire extinguishing robot 7 and the isolation fire extinguishing device 8. After receiving the instructions, both will immediately initiate the corresponding procedures and cooperate to complete the fire extinguishing and isolation tasks.

[0046] Combined Figure 2 、 Figure 3 、 Figure 4 and Figure 9 As shown, the fire extinguishing robot 7 includes a fire extinguishing robot slider 71 arranged on the suspended track 2. The fire extinguishing robot slider 71 is the basis for the stable movement of the fire extinguishing robot 7 on the suspended track 2. The fire extinguishing robot slider 71 ensures the structural stability and durability of the fire extinguishing robot 7 during long-term and high-frequency movement. The fire extinguishing robot slider 71 enables the fire extinguishing robot 7 to move smoothly and accurately along the track to the fire occurrence point, providing precise positioning support for subsequent fire extinguishing operations.

[0047] On the slider 71 of the fire extinguishing robot, there is a carbon dioxide fire extinguisher 72 and a robotic arm 73 of the fire extinguishing robot. The carbon dioxide fire extinguisher 72 is the main fire extinguishing equipment of the fire extinguishing robot 7. As an inert gas, carbon dioxide has the advantages of non-conductivity, non-pollution to the protected object, and leaving no traces, and is especially suitable for extinguishing fires of electrical equipment and precision instruments. In the fire extinguishing robot 7, the carbon dioxide fire extinguisher 72 is installed on the slider 71 of the fire extinguishing robot so that the robot can quickly bring it to the fire scene. The robotic arm 73 of the fire extinguishing robot is a key component connecting the slider 71 of the fire extinguishing robot and the carbon dioxide fire extinguisher 72. The robotic arm 73 of the fire extinguishing robot is not only responsible for accurately positioning the fire extinguisher at the fire point, but also bears the important task of controlling the spraying direction and intensity of the fire extinguishing agent. The robotic arm 73 of the fire extinguishing robot adopts a multi-degree-of-freedom design and has flexible spatial movement ability, which can ensure that the nozzle of the fire extinguisher accurately aims at the fire source in a complex environment.

[0048] On the robotic arm 73 of the fire extinguishing robot, there is a control valve 74 of the fire extinguishing robot. The control valve 74 of the fire extinguishing robot is responsible for receiving instructions from the fire hazard and automatic fire disposal system 4 and adjusting the spraying flow rate and duration of the fire extinguishing agent according to the instructions to achieve the best fire extinguishing effect.

[0049] The end of the robotic arm 73 of the fire extinguishing robot is connected to the nozzle of the carbon dioxide fire extinguisher 72. When the fire extinguishing robot 7 arrives at the fire scene, the robotic arm 73 of the fire extinguishing robot will adjust to the best spraying angle according to the system instructions, and then the control valve 74 of the fire extinguishing robot will open, and the carbon dioxide fire extinguishing agent will be sprayed out at high speed from the nozzle, quickly covering the fire source and blocking the air, so as to achieve the purpose of extinguishing the fire.

[0050] Combined Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown in, the isolation fire extinguishing device 8 includes an isolation slider 81 arranged on the suspended track 2. The isolation slider 81 ensures that the isolation fire extinguishing device 8 can move stably and quickly on the suspended track 2 to the fire scene. The isolation slider 81 also integrates a precise guiding and driving mechanism, enabling the isolation fire extinguishing device 8 to move smoothly and accurately along the track, providing precise positioning support for subsequent isolation fire extinguishing operations.

[0051] On the isolation slider 81, there is a fire extinguishing isolation cover 82. The fire extinguishing isolation cover 82 is responsible for forming a closed isolation space at the fire scene to prevent the further spread of the fire. Inside the fire extinguishing isolation cover 82, there is a fire extinguishing mechanism 83. The fire extinguishing mechanism 83 can spray steam according to the type and severity of the fire to quickly make the steam concentration reach more than 35% (volume percentage), so as to achieve the purpose of extinguishing the fire.

[0052] The fire extinguishing isolation cover 82 includes an isolation inner cover 821 fixedly connected to the isolation slider 81. On the outer side of the isolation inner cover 821, there are multiple layers of isolation outer covers 822 that can move up and down. On both sides of the top of the isolation outer cover 822, there is an isolation cover driving mechanism 84 for driving its up and down movement. The fire extinguishing isolation cover 82 is composed of the isolation inner cover 821 fixedly connected to the isolation slider 81 and the isolation outer cover 822 that can move up and down. The isolation inner cover 821 serves as the basic part of the isolation space, and its shape and size are designed according to the layout of the production line and the fire risk area to ensure that it can effectively cover the fire point. The isolation outer cover 822 can move up and down along the outer side of the isolation inner cover 821 under the drive of the isolation cover driving mechanism 84, thereby realizing the opening and closing of the isolation space.

[0053] The isolation cover driving mechanism 84 may adopt various driving methods such as electric, pneumatic, or hydraulic to ensure that the isolation outer cover 822 can be opened and closed quickly and accurately. The isolation cover driving mechanism 84 is usually installed on both sides of the top of the isolation outer cover 822 and is connected to the isolation outer cover 822 through a transmission device. When receiving a system instruction, the isolation cover driving mechanism 84 will be immediately activated, driving the isolation outer cover 822 to move up and down along the outer side of the isolation inner cover 821, thereby completing the opening and closing actions of the isolation space.

[0054] Combined Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown in

[0055] The fire extinguishing mechanism 83 includes water curtain nozzles 831 arranged around the top of the fire extinguishing isolation cover 82. The water curtain nozzles 831 adopt advanced spraying technology and can spray water in the form of tiny droplets to form a dense water curtain. There is also a steam nozzle on the top of the fire extinguishing isolation cover 82, which can quickly raise the steam concentration in the isolation cover to more than 35% (volume percentage) to achieve the purpose of extinguishing fire. The water curtain nozzles 831 are connected to a fire hose 832. The fire hose 832 ensures the structural stability and durability under the action of high-pressure water flow. One end of the fire hose 832 is connected to the water curtain nozzle 831, and the other end is connected to a fire water source. The steam nozzle 833 is connected to a steam hose 834, which is connected to the factory steam source. The fire hose 832 ensures the structural stability and durability under the action of high-pressure water flow. When receiving a fire extinguishing instruction, the fire water source will immediately inject high-pressure water flow into the hose, pushing the water flow through the hose into the water curtain nozzles 831, and finally forming a dense water curtain on the inner wall of the isolation cover. The fire hose 832 also has flexible bending and telescoping capabilities to adapt to fire extinguishing isolation covers 82 of different shapes and sizes, ensuring that the water curtain can evenly cover the entire isolation space. The steam hose should also have flexible bending and telescoping capabilities and be able to withstand high temperatures above 160°C.

[0055] During the fire extinguishing operation, the working process of the fire extinguishing mechanism 83 is usually as follows: First, the isolation fire extinguishing device 8 drives the fire extinguishing isolation cover 82 to quickly move to the fire site through its isolation cover driving mechanism 84, and the isolation cover is lowered. Then, the system starts the fire water source and injects high-pressure water flow into the fire hose 832. The water flow enters the water curtain nozzle 831 through the hose, forms a dense water curtain on the inner wall of the isolation cover, isolates the fire point from the external environment, and at the same time sprays steam for fire extinguishing.

[0056] Combined with Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the isolation cover driving mechanism 84 includes telescopic motors 841 arranged on both sides of the top of the fire extinguishing isolation cover 82. The output end of the telescopic motor 841 is connected with a lifting steel wire rope 842, and the end of the lifting steel wire rope 842 is fixedly connected with the isolation outer cover 822.

[0057] Specifically, the telescopic motors 841 are installed on both sides of the top of the fire extinguishing isolation cover 82. The telescopic motors 841 can be quickly started after receiving the system instruction and generate enough driving force to drive the lifting steel wire rope 842 to perform lifting and lowering movements. The telescopic motors 841 have the advantages of small volume, light weight, and large power, and can provide stable power output in a limited installation space. At the same time, they also have intelligent control functions and can adjust the rotation speed and direction of the motors according to the system instruction to achieve precise control of the isolation outer cover 822.

[0058] Connected to the telescopic motor 841 is the lifting steel wire rope 842. One end of the lifting steel wire rope 842 is connected to the output end of the telescopic motor 841, and the other end is fixedly connected to the isolation outer cover 822 through a special connecting device. When the telescopic motor 841 is started, the telescopic motor 841 will drive the lifting steel wire rope 842 to perform lifting and lowering movements, thereby driving the isolation outer cover 822 to move up and down along the outside of the isolation inner cover 821.

[0059] During the working process of the isolation cover driving mechanism 84, the intelligent control components of the system play a crucial role. These control components can receive the instructions from the fire hazard and automatic fire disposal system 4 in real time and adjust the rotation speed and direction of the telescopic motor 841 according to the instructions. They can monitor key parameters such as the tension and speed of the lifting steel wire rope 842 to ensure the stability and safety of the isolation outer cover 822 during the lifting and lowering process. When necessary, the system can also start the emergency braking device to prevent the isolation outer cover 822 from getting out of control due to unexpected situations.

[0060] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, during the fire disposal process, the pollutant collection system 5 includes a collection floor drain 51 installed on the outer floor of the wet metallurgy extraction line 1 box. The collection floor drain 51 serves as the inlet of the pollutant collection system 5 during the fire disposal process and is installed on the outer floor of the wet metallurgy extraction line 1 box. These collection floor drains 51 ensure the structural stability and durability during the long-term and high-frequency pollutant discharge process.

[0061] The collection floor drain 51 is connected to a collection pipeline 52, and the collection pipeline 52 ensures that there will be no leakage due to corrosion or wear during the process of transporting pollutants.

[0062] The end of the collection pipeline 52 is connected to a collection tank 53, and the collection tank 53 is responsible for temporarily storing the pollutants collected from the collection floor drain 51. The collection tank 53 ensures that it can hold enough pollutants and can store them for a long time when necessary.

[0063] A wastewater transfer pump 54 is installed on the collection tank 53. The wastewater transfer pump 54 is responsible for transporting the pollutants in the collection tank 53 to the subsequent treatment facilities for further treatment. Necessary control devices and monitoring instruments are also installed on the pump body of the wastewater transfer pump 54 so that the operators can understand the working status of the pump in real time and make necessary adjustments.

[0064] During the fire disposal process, the working process of the pollutant collection system 5 during the fire disposal process is generally as follows: First, when a fire occurs, the fire extinguishing wastewater will enter the collection pipeline 52 through the collection floor drain 51. Then, the pollutants flow along the collection pipeline 52 to the collection tank 53 for temporary storage. When the pollutants in the collection tank 53 reach a certain quantity, the wastewater transfer pump 54 will be started to transport the pollutants to the subsequent treatment facilities for further treatment. During the whole process, the intelligent control components of the system will monitor the working status of each component in real time and issue an alarm or make automatic adjustments when necessary to ensure the stable and reliable operation of the system.

[0065] Combined Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in the figure, smoke sensors 9 are installed above the wet metallurgy extraction line 1, and the smoke sensors 9 are all wirelessly connected to the patrol robot 6, the fire extinguishing robot 7, and the isolation fire extinguishing device 8.

[0066] Specifically, the smoke sensors 9 ensure stable performance under long-term and harsh working conditions. The smoke sensors 9 also have a self-diagnosis function, which can monitor their own working status in real time and issue an alarm in time when a failure occurs to remind the maintenance personnel to carry out maintenance or replacement.

[0067] The inspection robot 6, the fire extinguishing robot 7, and the isolation fire extinguishing device 8 that establish a wireless communication connection with the smoke detector 9 together constitute an efficient and intelligent fire emergency response system. When the smoke detector 9 detects smoke particles in the air and confirms the occurrence of a fire, it will immediately send a fire alarm signal to the inspection robot 6, the fire extinguishing robot 7, and the isolation fire extinguishing device 8 through the wireless communication network.

[0068] After receiving the fire alarm, the inspection robot 6 will quickly start and conduct inspections along the preset inspection route. The inspection robot 6 is equipped with a variety of sensors such as a high-definition camera and an infrared thermal imager, which can collect real-time images and temperature information of the fire scene and transmit this information to the central control room in real time. Through the inspection of the inspection robot 6, the operator can quickly understand the situation of the fire scene and make corresponding decisions.

[0069] The fire extinguishing robot 7 is responsible for carrying out fire extinguishing operations at the fire scene. The fire extinguishing robot 7 is equipped with a carbon dioxide fire extinguisher and can select a suitable fire extinguishing method for fighting according to the type and severity of the fire. At the same time, the fire extinguishing robot 7 also has self-navigation and obstacle avoidance functions, and can move autonomously in the complex fire scene and find the best fire extinguishing position.

[0070] The isolation fire extinguishing device 8 is responsible for forming an isolation zone at the fire scene to prevent the further spread of the fire. When receiving the fire alarm, the isolation fire extinguishing device 8 will quickly start and move to the vicinity of the fire point. Then, through the coordinated work of components such as the internal fire extinguishing mechanism 83 and the isolation cover driving mechanism 84, the isolation outer cover 822 will be quickly unfolded and covered on the fire point to form a sealed isolation space. Inside this isolation space, the fire extinguishing mechanism 83 will spray water to form a water curtain on the inner wall of the isolation cover and at the same time spray water vapor for fire extinguishing operations, ultimately achieving the purpose of extinguishing the fire.

[0071] This is a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
