[0028] The purpose of this invention is to provide a water-cooling device for use on damaged cooling walls, so as to solve the problems existing in the prior art. It has a simple structure, is easy to use, can be quickly deployed and effectively cooled, ensure the normal operation of the blast furnace, and reduce production losses and safety risks caused by damage to the cooling walls.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This invention provides a water-cooling device for use with damaged cooling walls, such as... Figures 1-6As shown, the device includes: a cylinder 10, a cooling column 31, a first coolant circulation pipe, and a second coolant circulation pipe. The cylinder 10 is detachably and fixedly connected to the damaged area of ​​the blast furnace cooling wall, and a cooling inner cavity is provided inside the cylinder 10. The cooling column 31 is fixedly connected to the top of the cylinder 10, and one end of the cooling column 31 extends into the cooling inner cavity of the cylinder 10. One end of the first coolant circulation pipe is connected to the bottom of the cylinder 10 and communicates with the cooling inner cavity, while the other end is used to communicate with a coolant supply device. One end of the second coolant circulation pipe is connected to the side wall of the cylinder 10 and communicates with the cooling inner cavity, while the other end is used to communicate with a coolant supply device. It can be flexibly installed at the damaged area of ​​the blast furnace cooling wall. The detachable connection method facilitates the installation and disassembly of the device, making it suitable for use in different situations and at different damaged areas of different blast furnaces, thus improving the versatility and applicability of the device. The cooling inner cavity provides space for coolant circulation, which can better absorb the heat emitted from the damaged area of ​​the blast furnace, enhancing the cooling function of the device. The refrigeration column 31 extends into the cooling cavity, directly exchanging heat with the coolant within, significantly enhancing the overall cooling effect of the unit, improving the efficiency of localized cooling, effectively compensating for insufficient cooling caused by damage to the cooling walls, and better ensuring the stable operation of the blast furnace. It achieves a circulating supply of coolant; coolant supplied from the coolant supply equipment can stably enter the cooling cavity, carry away heat, and then flow back to the supply equipment for processing or resupply, ensuring the continuity and stability of the cooling process and effectively reducing the temperature at the damaged area of ​​the blast furnace. The increased circulation path and method of the coolant make the flow of coolant within the cooling cavity more uniform and sufficient. Supplementing coolant from the cylinder wall side to participate in the circulation allows for more comprehensive cooling of all areas within the cooling cavity, improving the uniformity of the cooling effect and further ensuring effective cooling of the damaged area of ​​the blast furnace.

[0031] In a preferred embodiment, the water-cooling device applied to the damaged cooling wall further includes a fixing circular plate 11. The fixing circular plate 11 is used to seal and fix the freezing column 31 to the cylinder 10. On the one hand, it ensures that the freezing column 31 is firmly connected to the cylinder 10 and will not loosen during the operation of the device, ensuring that the freezing column 31 plays a cooling role in the appropriate position. On the other hand, the sealed connection effectively prevents the leakage of coolant in the cooling cavity and the entry of external substances, ensuring the normal operation of the cooling system and the cleanliness of the equipment interior. It also helps to reduce heat loss and improve cooling efficiency.

[0032] In a preferred embodiment, the water-cooling device applied to the damaged cooling wall further includes a protective sleeve 15. The protective sleeve 15 is used to fit over the portion of the freezing column 31 that extends out of the cylinder 10, and the bottom end of the protective sleeve 15 is detachably fixed to the fixed circular plate 11. The protective sleeve 15 can protect the portion of the freezing column 31 extending out of the cylinder 10 from external environmental factors, such as dust and hot gas impact inside the furnace, preventing damage to the surface of the freezing column 31 or performance degradation, and extending the service life of the freezing column 31. The detachable connection method facilitates the installation and replacement of the protective sleeve 15, and allows for timely replacement when the protective sleeve 15 is damaged, without affecting the stability of other parts of the equipment structure.

[0033] In a preferred embodiment, the water-cooling device applied to the damaged cooling wall further includes a fixing ring plate 12 and multiple limiting bolts 14. The fixing ring plate 12 is sleeved on the bottom end of the protective sleeve 15 for fixed connection. The fixing ring plate 12 has multiple first through holes 13 circumferentially arranged, and the fixing circular plate 11 has first threaded holes corresponding to the first through holes 13 circumferentially arranged. The limiting bolts 14 are used to pass through the first through holes 13 and threadedly connect with the first threaded holes. Through the cooperation and connection between the fixing ring plate 12, the limiting bolts 14 and the fixing circular plate 11, the stability and reliability of the connection between the protective sleeve 15 and the fixing circular plate 11 are further enhanced. During equipment operation, the protective sleeve 15 is better fixed to prevent shaking or displacement, ensuring that it can continuously and effectively protect the freezing column 31.

[0034] In a preferred embodiment, the first coolant circulation pipeline includes a first delivery pipe 16, a first valve 19, and a second delivery pipe 17.

One end of the second delivery pipe 17 is connected to and communicates with the first valve 19, while the other end is connected to the coolant supply equipment. This segmented structural design makes the flow path of the coolant clearer and more controllable. The first valve 19 allows operators to flexibly adjust the flow rate and velocity of the coolant in the first coolant circulation pipeline according to actual cooling needs, ensuring that the cooling cavity can be provided with appropriate cooling capacity under different blast furnace cooling conditions and damage levels.

[0035] In a preferred embodiment, the end of the second infusion pipe 17 furthest from the first valve 19 is provided with a first threaded groove 18. The first threaded groove 18 is used for threaded connection and communication with the pipe of the coolant supply equipment. The threaded connection makes the connection between the second infusion pipe 17 and the coolant supply equipment more secure and provides better sealing performance, effectively preventing coolant leakage at the connection. At the same time, the threaded connection facilitates quick installation and disassembly of the connecting pipe between the equipment and the coolant supply equipment, which is beneficial for equipment maintenance and commissioning.

[0036] In a preferred embodiment, the second coolant circulation pipeline includes a third delivery pipe 20, a second valve 23, and a fourth delivery pipe 21.

One end of the fourth delivery pipe 21 is connected to and communicates with the second valve 23, while the other end is connected to the coolant supply equipment. Similar to the structural design of the first coolant circulation pipeline, this segmented structure and the second valve 23 allow for flexible control of the flow rate and velocity of the coolant in the second coolant circulation pipeline. This enables adjustments to be made as needed when the cooling inner cavity is replenished with coolant from the side, further optimizing the uniformity and efficiency of the cooling effect and improving the overall device's targeted cooling of the damaged parts of the blast furnace.

[0037] In a preferred embodiment, the end of the fourth infusion pipe 21 furthest from the second valve 23 is provided with a second threaded groove 22. The second threaded groove 22 is used for threaded connection and communication with the pipe of the coolant supply equipment. Similarly, the second threaded groove 22 also makes the connection between the fourth infusion pipe 21 and the coolant supply equipment more stable and reliable, reducing the risk of coolant leakage. Furthermore, it facilitates pipe connection and disassembly operations, which is beneficial for daily inspection and maintenance of the equipment and for adapting to different coolant supply equipment in different scenarios.

[0038] In a preferred embodiment, the water-cooling device applied to the damaged cooling wall further includes a first water inlet pipe 24, a third valve 27, a second water inlet pipe 25, and a first connecting pipe 26. One end of the first water inlet pipe 24 is fixedly connected to the side wall of the cylinder 10 and communicates with the cooling cavity, while the other end is connected to and communicates with the third valve 27. One end of the second water inlet pipe 25 is connected to and communicates with the third valve 27, while the other end is connected to and communicates with the first connecting pipe 26. The first connecting pipe 26 is used to connect to and communicate with water supply equipment, providing an additional water supply channel for the cooling cavity. By controlling the third valve 27, water can be flexibly injected into the cooling cavity according to the actual cooling needs of the blast furnace. This helps to adjust parameters such as the concentration, temperature, and volume of the coolant in the cooling cavity, further optimizing the cooling performance of the device and improving its adaptability to different cooling demand scenarios.

[0039] In a preferred embodiment, a protective rubber ring 28 is fitted onto the outer wall of the first water inlet pipe 24. The protective rubber ring 28, fitted onto the outer wall of the first water inlet pipe 24, serves a sealing and buffering function. During device operation, it effectively prevents coolant leakage from the cooling cavity along the connection between the first water inlet pipe 24 and the side wall of the cylinder 10, ensuring normal circulation of coolant within the cooling cavity and improving the sealing and reliability of the cooling system. Furthermore, the protective rubber ring 28 also buffers the impact of water flow on the connection between the first water inlet pipe 24 and the cylinder 10, reducing loosening and damage caused by frequent impacts, extending the device's service life, and ensuring long-term stable operation to maintain good cooling performance.

[0040] In a preferred embodiment, the water-cooling device applied to the damaged cooling wall further includes a first drain pipe 29, a fourth valve 30, a second drain pipe, and a second connecting pipe. One end of the first drain pipe 29 is fixedly connected to the side wall of the cylinder 10 and communicates with the cooling inner cavity, while the other end is connected to and communicates with the fourth valve 30. One end of the second drain pipe is connected to and communicates with the fourth valve 30, while the other end is connected to and communicates with the second connecting pipe, which is used to connect to and communicate with a water supply device. The first drain pipe 29 and related structures provide drainage for the cooling inner cavity. When the cooling process is complete or the liquid state in the cooling cavity needs to be adjusted, the liquid in the cooling cavity can be discharged in a timely manner by controlling the fourth valve 30. This helps maintain the stability and hygiene of the liquid environment in the cooling cavity, avoids problems such as decreased cooling performance caused by liquid accumulation, and ensures continuous and stable operation of the device to achieve efficient cooling.
