Description

Technical Field

[0001] This utility model belongs to the field of metallurgical equipment technology, specifically relating to a device for quickly reinstalling air vents and two sets. Background Technology

[0002] The blast furnace tuyeres and secondary tuyeres are key components in the blast furnace ironmaking process. The blast furnace tuyeres connect the hot blast system to the blast furnace body, and their main function is to evenly inject high-temperature hot blast (typically 1200–1350°C) into the furnace, promoting coke combustion and providing heat and reducing gases for the iron ore reduction reaction. However, the blast furnace tuyeres and secondary tuyeres are subjected to high temperatures, high pressures, and chemical corrosion over long periods, making them prone to damage.

[0003] Currently, the traditional method for replacing blast furnace tuyeres and secondary tuyeres requires the cooperation of multiple people. During blast furnace shutdown operations, the replacement work must be completed with high quality and quantity, which is time-consuming, labor-intensive, and difficult to guarantee installation accuracy, thus affecting blast furnace production efficiency. This method also leads to problems such as the inability to quickly and accurately locate leaks when installing tuyeres and secondary tuyeres, the need for multiple people to work together, low efficiency in the installation process, poor sealing effect, and inability to completely eliminate air leakage during blast furnace ventilation. Utility Model Content

[0004] This invention provides a device for quickly reinstalling air vents and two sets of equipment, which solves the problems of low efficiency and poor sealing effect in the existing installation process, which requires multiple people to cooperate.

[0005] The technical solution of this utility model is: a device for quick reinstallation of air vents and two sets, including a worktable and a push-pull rod. The worktable is provided with a positioning plate and two fixing plates. A roller is rotatably connected between the two fixing plates. The positioning plate is installed on the side of the roller. The positioning plate has a positioning hole in the center. The bottom of the positioning hole is at the same level as the top of the roller. The push-pull rod passes through the positioning hole and contacts the roller. The diameter of the positioning hole is adapted to the outer diameter of the push-pull rod.

[0006] As a further improvement of this utility model, a support base is fixedly installed at the bottom of the workbench to facilitate the alignment of the push-pull rod with the air vent and the two sets.

[0007] The beneficial effects of this utility model are as follows: This utility model achieves rapid positioning and installation of the replacement mechanism through rollers and positioning plates on the workbench, making the replacement of tuyeres and secondary sets more intuitive and convenient. It significantly shortens the replacement time of tuyeres and secondary sets, reducing blast furnace downtime. The tuyeres and secondary sets installed via push-pull rods have high sealing strength, preventing air leakage after blast furnace air supply, and ensuring high reliability. Simultaneously, this utility model reduces the number of personnel required for replacement, improves work efficiency, effectively reduces labor intensity, and meets the requirements of time-saving, labor-saving, and safe replacement of tuyeres and secondary sets. This utility model has a simple structure, stable operation, simplifies the operation process of replacing tuyeres and secondary sets, ensures installation accuracy, and facilitates operator handling and adjustment of the device, making it highly applicable and widely applicable.

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0011] like Figure 1 As shown, a device for quickly reinstalling air vents and two sets includes a worktable 5 and a push-pull rod 3. The worktable 5 is provided with a positioning plate 1 and two fixing plates 7. A roller 6 is rotatably connected between the two fixing plates 7. The positioning plate 1 is installed on the side of the roller 6. The positioning plate 1 has a positioning hole 2 in the center. The bottom of the positioning hole 2 is at the same level as the top of the roller 6. The push-pull rod 3 passes through the positioning hole 2 and contacts the roller 6. The diameter of the positioning hole 2 is adapted to the outer diameter of the push-pull rod 3.

[0012] The bottom of the workbench 5 is fixedly equipped with a support base 4, which makes it easy to align the push-pull rod 6 with the air vent 8 and the two sets 9.

[0013] In use, align the tuyeres 8 and 9 to be replaced beforehand. Move the device to the side of the tuyeres 8 and 9 to be replaced using the handles on both sides of the workbench 5. Make fine adjustments to ensure that the workbench 5 is on the same horizontal plane as the tuyeres 8 and 9. Pass the push-pull rod 3 through the positioning hole 2 and adjust the push-pull rod 3 so that it is tangent to the support roller 6, so that the push-pull rod 3 can move horizontally. Push and pull the tuyeres 8 and 9 at any angle back and forth to continuously push them horizontally, thus installing the tuyeres 8 and 9. The continuous horizontal force can improve the stability of the installation and effectively avoid poor sealing caused by uneven force, thus preventing air leakage after the blast furnace is blasted.
