[0003] Before the hearth is poured, the residual iron in the hearth needs to be drained and the materials need to be removed. During the process of lowering the burden surface of the blast furnace, the materials in the furnace are in a pile tip shape. The water injection operators need to hold the water injection pipes outside the furnace to perform the tip cutting operation on the pile tip of the material surface, flatten the tip of the material, so that a small excavator can be hoisted down from the manhole at the top of the furnace for the material removal operation.

Detailed implementation manners

[0025] Please refer to Figure 2 , the present application provides a blast furnace water injection pipe fixing device, including a frame 6, a first sleeve 9 and a second sleeve 1.

[0026] It should be pointed out in advance that Figure 2 is the top view of this device, Figure 2 the orientations of the first sleeve 9 and the second sleeve 1 in Figure 1 are not the respective orientations of the sleeves when this device is in the working state, Figure 1 while

[0027] shows the respective orientations of the sleeves when this device is in the working state. As shown in

[0028] Regarding the first sleeve 9, the first sleeve 9 is installed on the first rod 6a, and a number of first adjustable fixing members 17 are installed on the first sleeve 9. When the water injection pipe 19 passes through the first sleeve 9, the water injection pipe 19 is locked by the first adjustable fixing member 17.

[0029] Regarding the second sleeve 1, the second sleeve 1 is installed on the fourth rod 6d, and a number of second adjustable fixing members 14 are installed on the second sleeve 1. When the water injection pipe 19 passes through the second sleeve 1, the water injection pipe 19 is locked by the second adjustable fixing member 14.

[0030] During specific use, please refer to Figure 1 and Figure 2 , the frame 6 is located outside the hearth, firmly clamping the clamping assembly 5 on the tuyere water-cooled copper plate 18, thereby fixing the device to the tuyere water-cooled copper plate 18. The tuyere water-cooled copper plate 18 is located at the shaft position of the hearth. The device maintains a horizontal state or a substantially horizontal state during use. Figure 1 and Figure 2 The figure shows a top view of the device. After fixing the device to the tuyere water-cooled copper plate 18, the water injection pipe 19 is installed on the device. Specifically, the water injection pipe 19 extends into the hearth through the first sleeve 9 and the second sleeve 1. The first adjustable fixing member 17 cooperates with the first sleeve 9 to fix the tail of the water injection pipe 19, and the second adjustable fixing member 14 cooperates with the second sleeve 1 to fix the middle of the water injection pipe 19, so that the water injection pipe 19 passes through the tuyere water-cooled copper plate 18 and the head of the water injection pipe 19 extends from the tuyere water-cooled copper plate 18 into the hearth of the blast furnace. After the water injection pipe 19 is installed, the water supply stop valve is opened to inject water into the furnace. Water injection is carried out on the furnace burden in the furnace to cut the heap top, and the residual iron and coke in the hearth are cooled.

[0031] Adopting the solution of the present application, it is not necessary for the water injection personnel to hold the water injection pipe 19 for a long time at the tuyere area for water injection operation, which significantly reduces the labor intensity. Each person can simultaneously take care of the water injection operations of multiple water injection pipes 19 corresponding to multiple tuyere water-cooled copper plates in the blast furnace one by one, reducing the number of operating personnel and improving the operation efficiency. On the other hand, it also improves the safety hazards existing when holding the water injection pipe 19 and improves the operation safety.

[0032] In some embodiments, both the first adjustable fixing member 17 and the second adjustable fixing member 14 are setscrews, which have the advantages of convenient implementation, low cost, and easy maintenance. Other adjustable fixing members involved below can also adopt the implementation form of setscrews. It should be added that the adjustable fixing member can also adopt other implementation schemes, such as pipe clamps and pipe hoops.

Specifically, please refer to Figure 2, the rod body of the fourth rod 6d is fixedly connected to the first connecting sleeve 11a and the second connecting sleeve 11b. The first connecting sleeve 11a and the second connecting sleeve 11b are both provided with pin holes. The first connecting sleeve 11a and the second rod 6b are detachably connected through a pin 12 cooperating with the pin hole, and the second connecting sleeve 11b and the third rod 6c are detachably connected through a pin 12 cooperating with the pin hole. By detachably connecting with the fourth rod 6d through a U-shaped bracket-like structure, on the one hand, the portability of the device is improved, and it can be disassembled and then transported. On the other hand, it has the technical effect of meeting the requirements of different large sleeve sizes and working radii, and various sizes of U-shaped bracket-like structures can be set to connect with the fourth rod 6d.

In some embodiments, please refer to Figure 2 , the clamping assembly 5 includes a pressing plate 5a, two screw rods 5b, and nuts 5c threadedly installed on each screw rod 5b. One end of each screw rod 5b is fixedly connected to the fourth rod 6d. The two screw rods 5b are arranged in parallel at intervals. The pressing plate 5a is provided with two through holes, and the two screw rods 5b respectively pass through the two through holes movably. The nuts 5c are arranged on the side of the pressing plate 5a away from the fourth rod 6d. Among them, a limiting area 5dd is formed by enclosing the fourth rod 6d, the two screw rods 5b, and the pressing plate 5a. Figure 1 shows the convex and vertical structure 18a of the tuyere large sleeve 18. When the device is specifically installed, the convex and vertical structure 18a is placed in the limiting space. Tighten the nut 5c on the screw rod 5b to drive the pressing plate 5a to move towards the fourth rod 6d until the convex and vertical structure 18a is tightly pressed between the fourth rod 6d and the pressing plate 5a.
