Description

Technical Field

[0001] This application relates to the field of steel slag treatment technology, and in particular to an intelligent steel slag granulation production system and a production cooling method. Background Technology

[0002] In the field of metallurgical technology, the treatment of molten steel slag generated during steelmaking is a crucial step. Its effectiveness not only affects the quality and efficiency of steel production but also is closely linked to safety and environmental protection during the production process. Effective steel slag treatment methods can achieve the rational utilization of resources, reduce waste emissions, and are of great significance to the sustainable development of the steel industry.

[0003] Currently, the steelmaking industry commonly uses a combination of roll pressing and hot quenching processes to treat molten steel slag. In the roll pressing stage, the high-temperature molten steel slag is cooled by rapid water cooling, while a granulator crushes the slag into high-temperature granules. This process is generally manually controlled; operators check the dryness of the slag bed after each roll pressing. If water accumulates on the bed, pouring in molten steel slag again could trigger a serious explosion. Furthermore, the slag after roll pressing typically enters a hot quenching process to further reduce its temperature.

[0004] However, manual control requires a high level of experience and skill from operators, and human judgment is inherently subjective and uncertain, making it difficult to accurately determine whether the bed surface is dry each time. This makes it impossible to completely avoid explosions caused by water accumulation. Furthermore, during the heat treatment phase, it is difficult to precisely control the temperature of the steel slag manually. When the temperature of the steel slag is too high, hydrogen gas can be generated, potentially leading to a hydrogen explosion. Summary of the Invention

[0005] To ensure production safety and quality, this invention provides an intelligent steel slag granulation production system and a production cooling method.

[0006] The present invention provides an intelligent steel slag granulation production system, which adopts the following technical solution: An intelligent steel slag granulation production system includes a production module; The monitoring module is used to monitor the production process of the production module in real time and collect data; The intelligent analysis module is used to analyze and process the data collected by the monitoring module, and generate adjustment instructions for the production module; and The dynamic control module is used to receive and execute the adjustment command; The production module includes a sealed hood, a tilting machine, a granulating bed, a granulator, and a spray structure. The sealed hood has a door at the top, and the tilting machine is located below the door. The tilting machine includes a tilting device and a first driving device. The tilting device is connected to the inner wall of the sealed hood, and the first driving device is connected to the tilting device. The granulating bed includes a moving bed, support rollers, and a second driving device. Multiple support rollers are arranged in parallel, and the moving bed abuts against the top of the support rollers. The second driving device is connected to the support rollers and drives the moving bed to move on the support rollers. The granulator includes a granulating roller and a third driving device. The granulating roller is connected to the inner wall of the sealed hood, and the third driving device is connected to the granulating roller. The spray structure is connected to the sealed hood and located above the moving bed, used to spray the steel slag on the moving bed to cool the steel slag. The monitoring module and the dynamic control module are both electrically connected to the spray structure.

[0007] By adopting the above technical solutions, real-time monitoring, data analysis, and dynamic adjustment of the intelligent steel slag granulation production process can be achieved; molten steel slag can be safely tilted onto a moving bed, and the moving bed and granulation rollers can be driven to process the steel slag; the steel slag on the moving bed can be sprayed and cooled through a spray structure; and based on the real-time data from the monitoring module, the intelligent analysis module can generate adjustment commands, which are then executed by the dynamic control module to ensure the safety, stability, and efficiency of the production process.

[0008] Preferably, the spray structure includes a spray pipe and multiple multi-functional nozzles, all of which are connected to the spray pipe. The multi-functional nozzles are configured to spray water into the steel slag in various forms, including columnar and fan-shaped water flows. If the water jet from the multifunctional nozzle is columnar, the water falling onto the granulation bed will be distributed in a dotted pattern. If the water jet from the multifunctional nozzle is fan-shaped, the water will fall onto the granulation bed in a linear distribution, thus covering the entire width of the granulation bed in a linear coverage manner.

[0009] By adopting the above technical solution, the multi-functional nozzles can form water flow patterns of different shapes. Columnar water flow falls onto the granulation bed in a point-like distribution, while fan-shaped water flow falls onto the granulation bed in a linear distribution, covering the entire width of the granulation bed in a linear coverage manner. This allows for the selection of appropriate spraying methods to cool the steel slag based on its different temperatures and distribution patterns, improving the accuracy and effectiveness of cooling. Simultaneously, the system can achieve real-time monitoring, data analysis and processing, and execution of adjustment commands for the production module's production process, utilizing various devices within the production module to complete the treatment and cooling of the steel slag.

[0010] Preferably, the spray pipe is connected to a regulating valve for adjusting the water flow rate of the multifunctional nozzle, and the regulating valve is electrically connected to the dynamic control module.

[0011] By adopting the above technical solution, the water flow rate of the multi-functional nozzle can be adjusted by regulating the valve. Combined with the intelligent steel slag granulation production system for monitoring and analyzing the steel slag temperature, more precise cooling treatment of steel slag can be achieved, improving the safety and stability of the steel slag treatment process and avoiding safety hazards such as water accumulation caused by improper water flow rate.

[0012] This invention also provides a method for cooling during intelligent steel slag granulation production, comprising the following steps: S1. Open the door of the sealed enclosure, place the slag pot containing molten steel slag on the tilting machine, and close the door; S2. The first drive device drives the tilting device to rotate and pour the molten steel slag onto the moving bed. The second drive device drives the moving bed to make reciprocating linear motion so that the steel slag is spread in different areas of the moving bed. S3, the third drive device drives the granulation roller to rotate in both directions to cool and crush the steel slag; S4. The monitoring module collects data from the production module in real time and transmits the monitoring data to the intelligent analysis module. S5, the intelligent analysis module generates the optimal adjustment command based on the comprehensive analysis of monitoring data; S6. The dynamic control module receives the optimal adjustment command and controls the production module in real time to achieve cooling of steel slag.

[0013] By adopting the above technical solution, the monitoring module collects steel slag monitoring data in real time, the intelligent analysis module analyzes and generates adjustment instructions, and the dynamic control module executes the instructions to control the production module. This can achieve the cooling treatment of steel slag. Furthermore, through the cooperation of the tilting machine, moving bed and granulating roller, the steel slag can be spread more evenly and cooled and crushed.

[0014] Preferably, in step S4, the monitoring module includes: The steel slag temperature identification unit is installed on a sealed cover to collect real-time temperature data of steel slag in various areas of the granulation bed. The steel slag weight monitoring unit is installed on the support rollers and is used to monitor the weight of the moving bed and the steel slag on the moving bed. The moving bed displacement monitoring unit is used to collect the relative positions of the moving bed, granulator, and spray pipe in real time when the moving bed is in reciprocating motion. The spray angle monitoring unit is used to monitor the spray angle of the spray structure in real time; and The spray flow monitoring unit is used to monitor the instantaneous spray flow and the cumulative cooling spray flow.

[0015] By adopting the above technical solution, it is possible to collect in real time the temperature data of steel slag in various areas of the granulation bed, the weight of the moving bed and the steel slag on the moving bed, the relative position of the moving bed with the granulator and the spray pipe, the spray angle of the spray structure, the instantaneous spray flow rate and the cumulative cooling spray flow rate, providing accurate and comprehensive data for the intelligent analysis module, which facilitates the generation of reasonable adjustment instructions and realizes precise control of the steel slag cooling process.

[0016] Preferably, in step S5, the intelligent analysis module receives all monitoring data collected by the monitoring module and analyzes the slag temperature in each area of ​​the moving bed and the position of the moving bed relative to the spray structure. If the slag temperature in all areas is above 600℃, a regional cooling command is generated, causing the water sprayed from the spray structure to form a fan shape and spray the areas where the slag temperature is above 600℃ until the slag temperature is below 600℃. If some areas are above 600℃ and other areas are below 600℃ and above 200℃, then maintain the area cooling command and generate a command to reduce the spray flow rate, reduce the opening of the regulating valve to reduce the instantaneous spray flow rate until the temperature of some areas is above 600℃ and the temperature of the steel slag is below 600℃. If the temperature in a local area is higher than 600℃, and the temperature in other areas is lower than 200℃ and higher than 100℃, then the steel slag area with a temperature higher than 600℃ will be moved to the bottom of the spray structure to generate a point cooling command, so that the water sprayed by the spray structure is in columnar shape and sprayed on the steel slag area with a temperature higher than 600℃, until the temperature of the steel slag in some areas with a temperature higher than 600℃ is lower than 600℃. If there is a region where the temperature is below 100℃, a uniform stirring command and a stop spraying command will be generated. The uniform stirring command will cause the moving bed and granulation roller to move and crush the steel slag until the temperature of all regions is above 100℃. If the slag temperature in all areas is below 600℃, a slag pushing command will be generated.

[0017] By adopting the above technical solution, regional cooling commands, point cooling commands, uniform stirring commands, spray stop commands, and slag pushing commands can be generated according to the temperature conditions of different areas of steel slag on the moving bed. This achieves precise cooling, avoids excessively low local temperatures, and allows for timely slag pushing when the steel slag temperature reaches the standard, ensuring safe, stable, and efficient production.

[0018] Preferably, in step S5, the intelligent analysis module calculates the actual weight of the steel slag each time by analyzing the weight change of the moving bed before and after receiving the steel slag, and sets a safe upper limit for the cumulative cooling spray flow rate for each processing based on historical data or experience. When the cumulative flow rate exceeds the safe upper limit, a stop spray command is generated, and the management personnel are alerted.

[0019] By adopting the above technical solution, the actual weight of the steel slag can be calculated based on the weight change of the moving bed before and after receiving the steel slag, and a safe upper limit for the cumulative cooling spray flow rate for each processing can be set. When the safe upper limit is exceeded, the cooling spray can be forcibly stopped and the management personnel can be alerted to avoid excessive cooling spray water volume and ensure the safe operation of the steel slag granulation production system.

[0020] Preferably, in step S5, the intelligent analysis module analyzes the relative position between the moving bed and the granulator, and generates a stop command and a reverse operation command when the moving bed runs to a position that matches the relative position limit set by the granulator.

[0021] By adopting the above technical solutions, the safe and stable operation of the moving bed and granulator during the production process is ensured, and problems such as collisions caused by improper positioning are avoided, thereby ensuring the normal operation and production efficiency of the intelligent steel slag granulation production system.

[0022] Preferably, in step S6, after receiving the optimal adjustment command, the dynamic control module can adjust the spray pattern and flow rate of the multi-functional nozzle, the operating frequency and direction of the moving bed, and the operating frequency and direction of the granulator.

[0023] By adopting the above technical solutions, more precise control of the steel slag cooling process can be achieved, making the steel slag cooling process more scientific and reasonable, and avoiding safety hazards such as water accumulation, thus ensuring the safety, stability and reliability of the production process.

[0024] Preferably, in step S6, the dynamic control module also receives control instructions from the management platform, which is used by managers to send operation instructions, and the control instructions issued by the management platform have a higher priority than the adjustment instructions generated by the intelligent analysis module.

[0025] By adopting the above technical solutions, managers can directly intervene and control the production process according to the actual situation, increasing the system's flexibility and operability.

[0026] In summary, the present invention has the following beneficial effects: 1. It can realize real-time monitoring, data analysis and dynamic adjustment of intelligent steel slag granulation production process; it can safely tilt molten steel slag onto the moving bed and drive the moving bed and granulation roller to process the steel slag; it can spray the steel slag on the moving bed to cool it down through the spray structure; it can also generate adjustment instructions by the intelligent analysis module based on the real-time data of the monitoring module, and then execute them by the dynamic control module to ensure the safety, stability and efficiency of the production process; 2. The intelligent analysis module analyzes the weight change of the moving bed before and after receiving steel slag, sets a safe upper limit for the cumulative cooling spray flow rate each time, and forcibly stops the cooling spray and notifies the management personnel when the upper limit is exceeded, which can prevent explosion accidents caused by water accumulation. 3. The intelligent analysis module generates instructions such as regional cooling, point cooling, uniform stirring, and slag pushing based on different steel slag temperatures. The dynamic control module executes the corresponding adjustments, which can achieve effective cooling and crushing of steel slag. Attached Figure Description

[0034] Example 1 A smart steel slag granulation production system, referring to Figure 1 and Figure 2 It includes a production module 1, a monitoring module 2, an intelligent analysis module 3, and a dynamic control module 4. Among them, the monitoring module 2 monitors and collects data on the production process of the production module 1 in real time, the intelligent analysis module 3 analyzes and processes the data collected by the monitoring module 2 to generate adjustment instructions, and the dynamic control module 4 receives and executes the adjustment instructions, realizing intelligent control and adjustment of the production module 1, and improving the safety and efficiency of steel slag granulation production.

[0035] The system can collect production data in real time through monitoring module 2, perform data analysis and generate instructions through intelligent analysis module 3, and execute adjustment instructions through dynamic control module 4. This effectively solves the problems of inaccurate manual control and inability to accurately regulate temperature in existing technologies, and reduces the risk of explosion accidents.

[0036] Reference Figure 1 Production module 1 includes a sealed enclosure 5, a tilting machine 6, a granulating bed 7, a granulator 8, and a spraying structure 9. The sealed enclosure 5 has a door 51 at its top, one end of which is hinged to the sealed enclosure 5, and the other end is slidably connected to the sealed enclosure 5. A hydraulic cylinder is hinged to the sealed enclosure 5, and the hydraulic cylinder is hinged to the door 51.

[0037] Reference Figure 1 The tilting machine 6 is located below the enclosure door 51. The tilting machine 6 includes a tilting device and a first drive device. The tilting device can be a bracket with a hinged structure, which is connected to the inner wall of the sealed enclosure 5 by high-strength bolts to ensure the stability of the connection. The first drive device can be a hydraulic motor, which is connected to the tilting device through a coupling and can provide a large torque to achieve stable rotation of the tilting device.

[0038] Reference Figure 1The granulation bed 7 includes a moving bed, support rollers, and a second drive unit. Multiple support rollers are arranged parallel to each other below the tilting machine. The surfaces of the support rollers are precision-machined to reduce friction with the moving bed. The moving bed abuts against the top of the support rollers. The second drive unit is a variable frequency motor, which is fixedly connected to a gear. The moving bed is fixedly connected to a rack, which meshes with the gear to precisely control the moving speed and position of the moving bed.

[0039] Reference Figure 1 The granulator 8 includes a granulating roller and a third drive unit. The granulating roller is connected to the inner wall of the sealed cover 5 via bearings to allow for flexible rotation. The third drive unit is a variable frequency motor, which can adjust the speed and direction of the granulating roller as needed.

[0040] Reference Figure 1 The spray structure 9 is connected to the sealed hood 5 and suspended above the moving bed to perform spraying operations on the steel slag conveyed by the moving bed. The spray structure 9 has at least one set, including a spray pipe and multiple multi-functional nozzles connected to the spray pipe. One end of the spray pipe is connected to a water source, and the other end extends through the sealed hood 5 to the top of the moving bed. Each nozzle is arranged on the spray pipe and sprays the steel slag. The multi-functional nozzles can be selected from turbine-type adjustable nozzles, impact-type adjustable nozzles, needle valve-type adjustable nozzles, or multi-channel combination nozzles.

[0041] Reference Figure 1 The multi-functional nozzle, adjusted via a fourth driving device, can spray water in different shapes, including columnar and fan-shaped streams. If the water from the liquid column nozzle is columnar, it falls onto the granulation bed 7 in a dotted distribution; if it is fan-shaped, it falls onto the granulation bed 7 in a linear distribution, covering the entire width of the granulation bed 7 in a linear manner. The fourth driving device uses a stepper motor or a micro servo motor to drive changes in the internal structure of the multi-functional nozzle, thereby adjusting the water flow pattern.

[0042] Reference Figure 1 The spray pipe is connected to a regulating valve, which can be an electric ball valve. The electric ball valve is electrically connected to the dynamic control module 4 through the controller, which can quickly and accurately adjust the water flow rate.

[0043] In this embodiment, the first driving device, the second driving device, the third driving device and the fourth driving device are all electrically connected to the dynamic control module 4.

[0044] Reference Figure 1 It also includes a slag receiving car and a slag trough fixedly connected to the slag receiving car, which facilitates the movement of the slag trough. The bottom of the sealed cover 5 is provided with a drop hole, and the top of the slag trough is provided and located below the drop hole, for receiving the cooled steel slag.

[0045] The implementation principle of this embodiment is as follows: This intelligent steel slag granulation production system achieves comprehensive monitoring and intelligent control of the steel slag granulation production process through the collaborative work of multiple modules. Monitoring module 2 collects various data during the production process in real time; intelligent analysis module 3 analyzes and processes the data to generate reasonable adjustment instructions; and dynamic control module 4 executes the instructions to adjust various structures of production module 1. This intelligent control method effectively avoids the subjectivity and uncertainty of manual control, precisely controls the cooling process of steel slag, eliminates safety hazards such as water accumulation, and improves the efficiency and quality of steel slag treatment, representing a significant improvement over existing technologies.

[0046] The spray structure 9 is designed to flexibly adjust the spray pattern and flow rate according to different cooling requirements. The rotation and angle control of the liquid jet nozzles can achieve precise cooling of specific areas, while the setting of the regulating valve can accurately control the water flow rate according to the actual situation of the steel slag, improving the cooling effect and efficiency, while also further enhancing the safety and reliability of the system.

[0047] Example 2 This embodiment also provides a method for cooling intelligent steel slag granulation production, referring to... Figure 1 , Figure 2 and Figure 3 This includes the following steps: S1. Open the door 51 of the sealed cover 5, place the slag pot containing molten steel slag on the tilting machine 6, and close the door 51.

[0048] In this step, the operator operates the hydraulic cylinder to slowly open the hood 51. Then, a crane is used to lift the slag pot containing high-temperature molten steel slag onto the tilting machine 6, ensuring that the slag pot is placed stably. Finally, the control panel is operated again to close the hood 51, reducing the possibility of leakage of high-temperature hot air and dust (greater than 1000°C).

[0049] S2. The first drive device drives the tilting device to rotate and pour the molten steel slag onto the moving bed. The second drive device drives the moving bed to make reciprocating linear motion so that the steel slag is spread in different areas of the moving bed.

[0050] The first drive unit starts, causing the tilting device to rotate and pour molten steel slag onto the moving bed. At the same time, the second drive unit starts working, causing the moving bed to reciprocate in a linear motion, spreading the steel slag on the moving bed.

[0051] S3, the third drive unit drives the granulation roller to rotate in both directions to cool and crush the steel slag.

[0052] The third drive unit starts, driving the granulating roller to rotate in both directions. The granulating roller squeezes and crushes the steel slag, and at the same time, it works in conjunction with the water sprayed from the spray structure 9 to cool and crush the steel slag.

[0053] S4. Monitoring module 2 collects data from production module 1 in real time and transmits the monitoring data to intelligent analysis module 3.

[0054] Monitoring module 2 includes a steel slag temperature identification unit, a steel slag weight monitoring unit, a moving bed displacement monitoring unit, a spray angle monitoring unit, and a spray flow rate monitoring unit.

[0055] The steel slag temperature identification unit can use an infrared temperature sensor, installed on the sealed enclosure 5, to collect real-time temperature data of the steel slag in various areas of the granulation bed 7 via an infrared monitoring system, and display the data for management personnel to inspect. The steel slag weight monitoring unit can use a weighing sensor, installed on the support rollers, to accurately detect the weight of the moving bed and the steel slag on it. The moving bed displacement monitoring unit can use a laser displacement sensor to provide real-time feedback on the relative position of the moving bed to the fixed granulator 8 and spray pipes during reciprocating motion. The spray angle monitoring unit can use an angle sensor to provide real-time feedback on the angle position of the liquid column nozzles. The spray flow rate monitoring unit can use an electromagnetic flow meter to record the instantaneous spray flow rate and cumulative cooling spray flow rate. These monitoring data are transmitted to the intelligent analysis module 3 via a data cable.

[0056] S5, Intelligent Analysis Module 3 generates optimal adjustment instructions based on comprehensive analysis of monitoring data.

[0057] After receiving the data transmitted by the monitoring module 2, the intelligent analysis module 3 analyzes the slag temperature in each area of ​​the moving bed and the position of the moving bed relative to the spray structure 9. If the temperature of the steel slag in all areas is higher than 600℃, a regional cooling command is generated, causing the water sprayed from the spray structure 9 to be in a fan shape to spray the areas where the temperature of the steel slag is higher than 600℃ until the temperature of the steel slag is lower than 600℃. If some areas are above 600℃ and other areas are below 600℃ and above 200℃, then maintain the area cooling command and generate a command to reduce the spray flow rate, reduce the opening of the regulating valve to reduce the instantaneous spray flow rate until the temperature of some areas is above 600℃ and the temperature of the steel slag is below 600℃. If the temperature in a local area is higher than 600℃, and the temperature in other areas is lower than 200℃ but higher than 100℃, then the steel slag area with a temperature higher than 600℃ will be moved below the spray structure 9 to generate a point cooling command, so that the water sprayed from the spray structure 9 will be in a column shape and sprayed onto the steel slag area with a temperature higher than 600℃ until the temperature of the steel slag in the local area is lower than 600℃, and until the temperature of the steel slag in some areas with a temperature higher than 600℃ is lower than 600℃. If the temperature in any area is below 100°C, a uniform stirring command and a stop spraying command are generated. The uniform stirring command causes the moving bed and granulating roller to move to crush the steel slag until the temperature in all areas is above 100°C. The crushing configuration is as follows: the granulator 8 rotates clockwise and the moving bed moves to the left, or the granulator 8 rotates counterclockwise and the moving bed moves to the right. If the slag temperature in all areas is below 600℃, a slag pushing command is generated. The slag pushing command is configured as follows: the granulator 8 rotates clockwise and the moving bed moves to the right, pushing the slag out from the left side of the moving bed and into the slag trough on the slag receiving car below; or the granulator 8 rotates counterclockwise and the moving bed moves to the left, pushing the slag out from the right side of the moving bed and into the slag trough on the slag receiving car below.

[0058] After the slag pushing command is completed, the temperature recognition unit monitors the temperature of each area of ​​the moving bed. If the temperature of each area is higher than 100℃, it waits to enter the next step S1-S5. If the temperature in any area is below 100℃, an alarm will be triggered to alert management personnel. They will then manually check if there is water accumulation on the moving bed. If water is present, it will be cleaned up until all water is removed. If there is no water, the water will be drained manually and / or high-temperature steel slag will be pushed into the area using granulation rollers to bake it until the temperature in each area is above 100℃.

[0059] Furthermore, the intelligent analysis module 3 also calculates the actual weight of the steel slag each time by analyzing the weight comparison before and after receiving the steel slag into the moving bed, and sets a safe upper limit for the cumulative cooling spray flow rate for each processing based on historical data or experience. When the cumulative flow rate exceeds the safe upper limit, the cooling spray is forcibly stopped, and the management personnel are alerted at the same time.

[0060] Furthermore, the intelligent analysis module 3 can also analyze the relative position of the moving bed and the granulator 8, and generate a stop command and a reverse operation command when the moving bed runs to a position that matches the relative position limit set by the granulator 8.

[0061] S6. Dynamic control module 4 receives the optimal adjustment command and controls production module 1 in real time to achieve cooling of steel slag.

[0062] After receiving the adjustment instructions generated by the intelligent analysis module 3, the PLC controller of the dynamic control module 4 adjusts the spray pattern and flow rate of the liquid column nozzle, the operating frequency and direction of the moving bed, and the operating frequency and direction of the granulator 8. For example, when the PLC controller receives a regional cooling instruction, the dynamic control module 4 controls the fourth drive device and the regulating valve to make the water sprayed from the multi-functional nozzle into a fan shape and increase the water spray flow rate; when it receives a point cooling instruction, the dynamic control module 4 controls the fourth drive device and the regulating valve to make the water sprayed from the multi-functional nozzle into a columnar shape for local cooling.

[0063] Furthermore, the dynamic control module 4 also receives control commands from the management platform, which is used by managers to send operation commands. The control commands issued by the management platform have a higher priority than the adjustment commands generated by the intelligent analysis module 3.

[0064] The operating principle of this application is as follows: This intelligent steel slag granulation production system achieves comprehensive monitoring and intelligent control of the steel slag granulation production process through the collaborative work of multiple modules. Monitoring module 2 collects various data during the production process in real time; intelligent analysis module 3 analyzes and processes the data to generate reasonable adjustment instructions; and dynamic control module 4 executes the adjustment instructions to regulate production module 1. This intelligent control method effectively avoids the subjectivity and uncertainty of manual control, precisely controls the cooling process of steel slag, eliminates safety hazards such as water accumulation, and improves the efficiency and quality of steel slag treatment, representing a significant improvement over existing technologies.
