Description

Technical Field

[0001] The present invention belongs to the technical field of control devices, and specifically relates to an intelligent control device for a blast furnace cooling device. Background Art

[0002] The intelligent control device for a blast furnace cooling device is mainly used to achieve automatic monitoring and precise control of the blast furnace cooling process. It can real-time monitor the temperature changes in various areas of the blast furnace through temperature sensors, automatically adjust the flow rate and temperature of the coolant according to the monitoring data to maintain the optimal working temperature of the blast furnace, be able to adjust the cooling parameters according to actual needs, improve the cooling efficiency, prevent equipment overheating and scaling, collect various operation data such as temperature, coolant flow rate, pressure, etc., record them for a long time, analyze the data to identify equipment performance trends and potential problems, facilitate early maintenance and fault warning, realize the automatic control of the cooling system, reduce manual operations, and improve work efficiency and safety.

[0003] However, during the use of existing blast furnaces, it is difficult to control and adjust the temperature. Most traditional blast furnaces rely on manual temperature monitoring, which not only fails to achieve comprehensive and real-time data collection but also easily causes data errors due to human factors, thus affecting the accurate judgment of the temperature inside the furnace. Moreover, the response speed of temperature adjustment is slow, making it difficult to effectively cope with rapidly changing working environments such as the type of materials and the properties of furnace charges. This lag may cause the blast furnace to overheat or be under-cooled under certain working conditions, affecting the smelting quality and efficiency. Many blast furnaces still adopt traditional control methods and lack an intelligent temperature control system, unable to automatically optimize cooling and heating strategies, resulting in increased energy consumption and unstable production.

[0004] Therefore, the present invention provides an intelligent control device for a blast furnace cooling device. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve the technical problem of the inconvenience in controlling the blast furnace temperature, the present invention proposes an intelligent control device for a blast furnace cooling device.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: An intelligent control device for a blast furnace cooling device according to the present invention includes a liquid storage tank and a cooling pipe. A bottom plate is fixedly connected to the bottom of the liquid storage tank. An intelligent controller is fixedly installed on the side of the liquid storage tank. A partition plate is fixedly installed inside the liquid storage tank. A pumping pump is fixedly installed on the top of the partition plate, and the pumping pump is electrically connected to the intelligent controller. The input end of the pumping pump is connected to the inside of the liquid storage tank through a pipe, and the output end of the pumping pump is connected to a delivery pipe. One end of the delivery pipe is connected to the input end of the cooling pipe. The output end of the cooling pipe is connected to a return pipe. Sensors are arranged in an array on the cooling pipe. A filtering component for filtering the coolant is arranged inside the liquid storage tank, and one end of the return pipe is connected to the filtering component. A replacement mechanism is arranged inside the liquid storage tank.

[0007] By adopting the above technical solution, the temperature is monitored by the sensor. The sensor is electrically connected to the intelligent controller and can transmit the detected temperature electrical signal to the intelligent controller. When the internal control module of the intelligent controller determines that the filtering temperature is too high based on the transmitted electrical signal, the intelligent controller will send an instruction to the pumping pump, and then the pumping pump will work. The pumping pump will extract the coolant inside the liquid storage tank through the pipe. After the extracted coolant enters the delivery pipe, it will flow into the cooling pipe. The blast furnace can be cooled down through the cooling pipe, thereby achieving the purpose of cooling the blast furnace, effectively reducing the working temperature of the blast furnace, preventing the equipment from being damaged due to overheating, prolonging the service life of the blast furnace, reducing the risk of accidents in a high-temperature environment, and appropriate cooling can maintain a stable operating state of the blast furnace, improve production efficiency, and ensure the continuous and stable operation of the blast furnace.

[0008] Preferably, a liquid injection pipe is connected to the liquid storage tank, and the liquid injection pipe is connected to the filtering component.

[0009] By adopting the above technical solution, it is convenient to add coolant into the liquid storage tank through the liquid injection pipe, and the filtering component can filter the coolant.

[0010] Preferably, a sealing door is arranged on the top of the liquid storage tank through a hinge, and the sealing door is located above the replacement mechanism.

[0011] By adopting the above technical solution, the sealing door can be moved to no longer seal the top of the liquid storage tank, and thus the filter screen can be cleaned and replaced.

[0012] Preferably, the filtering component includes a filtering tank, a frame, and a filter screen. The filtering tank is fixedly installed inside the liquid storage tank. The frame is arranged inside the filtering tank. The filter screen is fixedly installed inside the frame. A guiding mechanism is arranged inside the frame.

[0013] By adopting the above technical solution, the filter screen is unfolded inside the filter tank through the frame. After the coolant enters the filter tank, the coolant will flow through the filter screen, and the impurities carried by the coolant can be filtered through the filter screen.

A guiding groove is arranged inside the square frame, and one end of the square frame extends into the filter tank. The guiding rod is fixedly installed inside the square frame.

[0019] By adopting the above technical solution, when the driving motor works, it will drive the threaded rod to rotate. The rotation of the threaded rod will cause the threaded cylinder to move. When the threaded cylinder moves, it will push the frame to move. Thus, the lower frame can be moved into the filter tank. Then, the driving motor above moves in the reverse direction. Through the cooperation of the threaded rod and the threaded cylinder, the upper frame will move, and then drive the filter screen to move into the square frame. Then, by opening the sealing door, the filter screen can be cleaned and replaced. Thus, the filter screen can be cleaned without stopping the machine, which can maintain the continuous operation of the system, avoid production interruption caused by shutdown, ensure the stability and high efficiency of the production process, save the cost of labor and mechanical operation, and reduce the overall operating cost.

[0020] Preferably, water permeable holes are arranged in an array on the square frame.

[0023] By adopting the above technical solution, the protrusions at the bottom of the scraper can be deformed and are made of memory material. After experiencing deformation, they can return to their original shape and fit against the top of the filter screen. When the filter screen moves, the impurities filtered on the top of the filter screen can be removed. The scraped impurities will move onto the scraper. The scraper is inclined.

For the intelligent control device of a blast furnace cooling device described in the present invention, the cooling pipes and sensors are provided to facilitate the monitoring and adjustment of the blast furnace temperature. The cooling pipes are arranged around the blast furnace cooling area, and the temperature is monitored by the sensors. The sensors are electrically connected to the intelligent controller and can transmit the detected temperature electrical signal to the intelligent controller. When the internal control module of the intelligent controller determines that the filtering temperature is too high based on the transmitted electrical signal, the intelligent controller will send an instruction to the pumping pump, and then the pumping pump will work. The pumping pump will extract the coolant inside the liquid storage tank through the pipeline. After the extracted coolant enters the conveying pipe, it will flow into the cooling pipe, and the blast furnace can be cooled down through the cooling pipe, thereby achieving the purpose of cooling the blast furnace, effectively reducing the working temperature of the blast furnace, preventing the equipment from being damaged due to overheating, extending the service life of the blast furnace, reducing the risk of accidents in a high-temperature environment.

Detailed implementation manners

[0041] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0042] As Figures 1 to 9As shown in the figure, an intelligent control device for a blast furnace cooling device according to an embodiment of the present invention includes a liquid storage tank 1 and a cooling pipe 6. A bottom plate 2 is fixedly connected to the bottom of the liquid storage tank 1. An intelligent controller 3 is fixedly installed on the side of the liquid storage tank 1. A partition plate 30 is fixedly installed inside the liquid storage tank 1. A pumping pump 4 is fixedly installed on the top of the partition plate 30. The pumping pump 4 is electrically connected to the intelligent controller 3. The input end of the pumping pump 4 is communicated with the inside of the liquid storage tank 1 through a pipeline. The output end of the pumping pump 4 is connected to a delivery pipe 5. One end of the delivery pipe 5 is communicated with the input end of the cooling pipe 6. The output end of the cooling pipe 6 is connected to a return pipe 8. Sensors 7 are arranged in an array on the cooling pipe 6. A filtering assembly for filtering the coolant is arranged inside the liquid storage tank 1. One end of the return pipe 8 is communicated with the filtering assembly. When using the intelligent control device for the blast furnace cooling device to cool the blast furnace temperature, the cooling pipe 6 is arranged to surround the blast furnace cooling area. The temperature is monitored by the sensors 7. The sensors 7 are electrically connected to the intelligent controller 3 and can transmit the detected temperature electrical signal to the intelligent controller 3. When the internal control module of the intelligent controller 3 determines that the filtering temperature is too high according to the transmitted electrical signal, the intelligent controller 3 will send an instruction to the pumping pump 4, and then the pumping pump 4 will work. The pumping pump 4 will extract the coolant inside the liquid storage tank 1 through the pipeline. After the extracted coolant enters the delivery pipe 5, it will flow into the cooling pipe 6. The blast furnace can be cooled by the cooling pipe 6, thereby achieving the purpose of cooling the blast furnace, effectively reducing the working temperature of the blast furnace, preventing the equipment from being damaged due to overheating, extending the service life of the blast furnace, reducing the risk of accidents in a high-temperature environment. Appropriate cooling can maintain a stable operating state of the blast furnace, improve production efficiency, ensure the continuous and stable operation of the blast furnace, and controlling the blast furnace temperature helps to optimize the smelting process, promote the full reaction of materials, improve the metal recovery rate and product quality. The coolant that absorbs heat flows back into the filtering assembly through the return pipe 8. In the cooling system, over time, some metal particles, dirt and other impurities may be deposited. By filtering the impurities carried by the coolant through the filtering assembly, the operating efficiency of the system can be improved, and it can effectively prevent the impurities from causing wear, corrosion or blockage to the equipment, thereby extending the service life of the equipment. Keeping the system clean can reduce the frequency of maintenance and cleaning, thereby saving manpower and material resources and reducing the overall operating cost.

[0043] As Figure 4 shown, a liquid injection pipe 9 is connected to the liquid storage tank 1, and the liquid injection pipe 9 is communicated with the filtering assembly. It is convenient to add coolant into the liquid storage tank 1 through the liquid injection pipe 9, and the coolant can be filtered through the filtering assembly.

[0044] As Figure 1As shown, a sealing door 31 is provided at the top of the liquid storage tank 1 through a hinge, and the sealing door 31 is located above the replacement mechanism. The sealing door 31 is movable and no longer seals the top of the liquid storage tank 1, so that the filter screen 17 can be cleaned and replaced.

[0045] As Figure 2 , Figure 3 and Figure 6 shown, the filter assembly includes a filter tank 12, a frame 14 and a filter screen 17. The filter tank 12 is fixedly installed inside the liquid storage tank 1. The frame 14 is arranged inside the filter tank 12. The filter screen 17 is fixedly installed inside the frame 14. A guiding mechanism is arranged inside the frame 14. Through the frame 14, the filter screen 17 is unfolded inside the filter tank 12. After the coolant enters the filter tank 12, the coolant will flow through the filter screen 17, and the impurities carried by the coolant can be filtered through the filter screen 17.

[0046] As Figure 3 and Figure 6 shown, the guiding mechanism includes a guiding hole 15 and a guiding rod 16. The guiding hole 15 is arranged inside the frame 14. The guiding rod 16 penetrates through the guiding hole 15. Through the cooperation of the guiding rod 16 and the guiding hole 15, the frame 14 can be guided to move smoothly.

[0047] As Figure 6 shown, sealing rings 18 are symmetrically arranged around the frame 14. A through groove 32 is arranged on the filter tank 12, and the frame 14 is arranged inside the through groove 32. The frame 14 can seal the gap between the frame 14 and the through groove 32 through the sealing rings 18, so as to prevent the coolant from flowing to the outside through the through groove 32.

[0048] As Figure 2 , Figure 3 , Figure 4 and Figure 6As shown in the figure, the replacement mechanism includes a square frame 10, a threaded barrel 19, a threaded rod 20, and a driving motor 21. The square frame 10 is fixedly installed inside the liquid storage tank 1. The threaded barrel 19 is fixedly installed on the frame 14. The threaded rod 20 is threadedly connected inside the threaded barrel 19. The driving motor 21 is fixedly installed on the square frame 10, and the output end of the driving motor 21 is fixedly connected to one end of the threaded rod 20. A guide groove 22 is provided inside the square frame 10, and one end of the square frame 10 extends into the filter tank 12. The guide rod 16 is fixedly installed inside the square frame 10. When too much impurities are adsorbed on the filter screen 17, the impurities on the filter screen 17 are removed. Through the movement of the replacement mechanism, the driving motor 21 works to drive the threaded rod 20 to rotate. The rotation of the threaded rod 20 causes the threaded barrel 19 to move. When the threaded barrel 19 moves, it will push the frame 14 to move. Thus, the lower frame 14 can be moved into the filter tank 12. Then, the upper driving motor 21 moves in the reverse direction. Through the cooperation of the threaded rod 20 and the threaded barrel 19, the upper frame 14 moves, and then drives the filter screen 17 to move into the square frame 10. Then, the sealing door 31 is opened to clean and replace the filter screen 17. Thus, the filter screen 17 can be cleaned without stopping the machine, which can keep the system running continuously, avoid production interruption caused by shutdown, ensure the stability and efficiency of the production process, save the cost of labor and mechanical operation, reduce the overall operating cost, simplify the maintenance process, make the equipment maintenance more efficient and easy to manage.

[0049] As Figure 3 shown, the square frame 10 is provided with water permeable holes 13 in an array. The water stains entering the square frame 10 will return to the inside of the liquid storage tank 1 through the water permeable holes 13 for storage.

[0050] As Figure 7 shown, a support plate 23 is fixedly installed inside the square frame 10. A scraper 24 is fixedly installed on the support plate 23, and the scraper 24 is inclined. There is a protrusion at the bottom of the scraper 24 that fits with the top of the filter screen 17. A storage component is provided inside the square frame 10. The square frame 10 provides an installation space for the support plate 23, and the support plate 23 provides an installation space for the scraper 24. The protrusion at the bottom of the scraper 24 is deformable and is made of a memory material. It can return to its original shape after experiencing deformation and fit with the top of the filter screen 17. When the filter screen 17 moves, the impurities filtered on the top of the filter screen 17 can be removed. The scraped impurities will move onto the scraper 24. The scraper 24 is inclined. When the filter screen 17 completely moves into the square frame 10, the top of the frame 14 will be in contact with the bottom of the scraper 24, thus forming a V-shaped groove. Through the V-shaped groove, the scraped stains will flow into the storage component for collection.

[0051] As Figure 8 and Figure 9As shown, the storage component includes a storage groove 25, a through hole 26, a waste groove 27, a baffle 28 and a sealing strip 29. The storage groove 25 is fixedly installed inside the square frame 10. The through hole 26 is provided on the storage groove 25 and is located on one side of the scraper 24. The waste groove 27 is arranged inside the storage groove 25. The baffle 28 is fixedly installed inside the waste groove 27. The sealing strip 29 is arranged around the waste groove 27. The dirt flowing through the through hole 26 will flow into the waste groove 27 for storage. The waste groove 27 can be pulled out to the outside, and then the dirt collected in the waste groove 27 can be processed.

[0052] Working principle: When the intelligent control device of the blast furnace cooling device is first used to cool down the temperature of the blast furnace, the cooling pipe 6 is arranged around the blast furnace cooling area. The temperature is monitored by the sensor 7, and the sensor 7 is electrically connected to the intelligent controller 3. The detected temperature electrical signal can be transmitted to the intelligent controller 3. When the internal control module of the intelligent controller 3 determines that the filtered temperature is too high, the intelligent controller 3 will send an instruction to the pumping pump 4, and then the pumping pump 4 will work. The pumping pump 4 will extract the coolant inside the liquid storage tank 1 through the pipeline. After the extracted coolant enters the inside of the delivery pipe 5, it will flow into the inside of the cooling pipe 6. The blast furnace can be cooled down through the cooling pipe 6, thus achieving the purpose of cooling the blast furnace, effectively reducing the working temperature of the blast furnace, preventing the equipment from being damaged due to overheating, prolonging the service life of the blast furnace, reducing the risk of accidents in a high-temperature environment. Appropriate cooling can maintain a stable operating state of the blast furnace, improve production efficiency, ensure the continuous and stable operation of the blast furnace, and controlling the blast furnace temperature helps to optimize the smelting process, promote the full reaction of materials, improve the metal recovery rate and product quality. The coolant that absorbs heat flows back into the inside of the filtration component through the return pipe 8. In the cooling system, over time, some metal particles, dirt and other impurities may be deposited. The filter screen 17 is unfolded inside the filter tank 12 through the frame 14. After the coolant enters the inside of the filter tank 12, the coolant will flow through the filter screen 17. The impurities carried by the coolant can be filtered through the filter screen 17. By filtering the impurities carried by the coolant through the filtration component, the operating efficiency of the system can be improved, and it can effectively prevent the impurities from causing wear, corrosion or blockage to the equipment, thereby prolonging the service life of the equipment. Keeping the system clean can reduce the frequency of maintenance and cleaning, thereby saving human and material resources and reducing the overall operating cost. When too many impurities are adsorbed on the filter screen 17, the impurities on the filter screen 17 are removed. Through the movement of the replacement mechanism, the driving motor 21 works to drive the threaded rod 20 to rotate. The rotation of the threaded rod 20 will cause the threaded barrel 19 to move. When the threaded barrel 19 moves, it will push the frame 14 to move, and then the lower frame 14 can be moved into the inside of the filter tank 12. Then the upper driving motor 21 moves in the reverse direction. Through the cooperation of the threaded rod 20 and the threaded barrel 19, the upper frame 14 will move, and then drive the filter screen 17 to move into the square frame 10. Then open the sealing door 31 to clean and replace the filter screen 17, and thus the filter screen 17 can be cleaned without stopping the machine, which can keep the system running continuously, avoid production interruption caused by shutdown, ensure the stability and high efficiency of the production process, save the cost of labor and mechanical operation, reduce the overall operating cost, simplify the maintenance process, and make the equipment maintenance more efficient and easy to manage.
