Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace tapping troughs, and particularly relates to a protection device for a large blast furnace tapping trough. Background Technique

[0002] The blast furnace iron storage trough plays a role in separating slag and iron, discharging molten iron into an iron ladle, and discharging molten slag into a slag trough. During the use of the trough, since the density of the molten slag is less than that of the molten iron, the molten iron is transported at the bottom of the trough (i.e., the iron line), and the molten slag is transported at the top of the trough (i.e., the slag line). The refractory material at the slag line part of the trough is damaged most severely due to high-temperature oxidation, molten slag erosion, penetration, and molten slag scouring.

[0003] The existing Chinese utility model patent with the reference publication number: CN216039657U discloses a device for discharging residual iron from a blast furnace tapping trough, including a trough and a rotating assembly; the trough: an extrusion ring is arranged inside, the extrusion ring fits with the groove of the trough, and uniformly distributed discharge grooves are arranged on the circumferential surface of the extrusion ring; the rotating assembly: includes a rotating shaft, a mounting frame, and a first motor. A rotating shaft is fixed inside the extrusion ring, the rotating shaft is rotatably connected inside the mounting frame, a first motor is mounted on the left side surface of the mounting frame, the output shaft of the first motor is fixed on the left end surface of the rotating shaft, and a connecting assembly is mounted on the upper side surface of the mounting frame. The extrusion ring is driven to rotate by setting the rotating assembly; among them: the input end of the first motor is electrically connected to the output end of an external control switch group, and the connecting assembly includes a sliding plate, a square rod, an extrusion plate, and a spring, which can very conveniently discharge the slag and iron inside the trough.

[0004] Although the above-mentioned device for discharging residual iron from a blast furnace tapping trough solves the problem that it is not convenient to discharge the iron slag inside the iron hook by placing the extrusion ring into the groove of the trough when discharging the residual iron by setting the extrusion ring, the cleaning effect of the above device is not good. At the same time, the temperature inside the trough is relatively high, and long-term contact is likely to cause the device to melt due to high temperature, thus affecting the use and resulting in insufficient protection effect for the trough. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the problem that the device is prone to melting due to high temperature after long-term use, resulting in insufficient cleaning effect and affecting the protection effect, and provides a protection device for a large blast furnace tapping trough.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Combined with the attached Figures 1-5, in this embodiment, a protection device for the blast furnace tapping runner includes: a top plate 1, two insertion plates 11 are fixedly installed on both sides of the bottom of the top plate 1, a support frame 12 is fixedly installed in the middle of the bottom of the top plate 1, the support frame 12 is in a "U" shape, a mounting motor 13 is fixedly installed at the bottom of one side of the support frame 12, a rotating column 14 is fixedly installed on one side of the mounting motor 13, a connecting ring 15 is fixedly installed on the outer side of the middle of the rotating column 14, and the connecting ring 15 is in a ring shape, and the bottom of the top plate 1 is movably connected to the runner main body 16.

[0026] Specifically, the operation of the mounting motor 13 can drive the rotating column 14 to rotate inside the support frame 12, thereby driving the rotating column 14 to rotate, and then driving the two tripod supports 2 to rotate.

[0027] Two tripod supports 2 are fixedly installed on both sides of the outer side of the connecting ring 15, three connecting motors 21 are fixedly installed on three sides of the tripod support 2, a rotating rod 22 is fixedly installed on one side of the connecting motor 21, a support ring 23 is fixedly installed on the outer side of the rotating rod 22, and the support ring 23 is in a ring shape, and a cleaning plate 24 is fixedly installed on the outer side of the support ring 23.

[0028] Specifically, the operation of the connecting motor 21 can drive the rotating rod 22 to rotate, thereby driving the support ring 23 and the cleaning plate 24 to rotate, and then cleaning the inside of the runner main body 16 through the rotation of the cleaning plate 24.

[0029] The outer side of the insertion plate 11 is movably connected to a fixing plate 3.

[0030] Two telescopic columns 31 are fixedly installed on both sides of the inner bottom of the fixing plate 3.

[0031] A bottom block 32 is fixedly installed at the bottom of the fixing plate 3, and two driving wheels 33 are fixedly installed on both sides of the bottom of the bottom block 32.

[0032] Specifically, the telescoping of the telescopic column 31 can drive the insertion plate 11 to move up and down inside the fixing plate 3, thereby adjusting the height of the protection device for the blast furnace tapping runner. The operation of the two driving wheels 33 on both sides of the bottom of the bottom block 32 can drive the protection device for the blast furnace tapping runner to move.

[0033] A rotating shaft 4 is fixedly installed on one side of the fixing plate 3, and a frame 41 is fixedly installed on one side of the rotating shaft 4.

[0034] An interception net 42 is fixedly installed on one side inside the frame 41, and a support rod 43 is fixedly installed in the middle of the inside of the frame 41.

The operation of the connecting motor 21 can drive the rotating rod 22 to rotate, so that the support ring 23 and the cleaning plate 24 outside it rotate, and the impurities deposited inside the runner main body 16 can be cleaned by the rotation of the cleaning plate 24, avoiding the problem of blockage of the runner main body 16, and at the same time improving the protection effect of the protection device of the blast furnace tapping runner. The operation of the installed motor 13 can drive the rotating column 14 to rotate, so that the connecting ring 15 rotates, driving the two tripod supports 2 to rotate. Thus, when the cleaning plate 24 becomes overheated due to long-term use, the cleaning plate 24 can be replaced by the rotation of the tripod support 2, so that the overheated cleaning plate 24 is separated from the runner main body 16 for heat dissipation, improving the practicability of the protection device of the blast furnace tapping runner, avoiding the problem of melting of the cleaning plate 24 caused by long-term use, and improving the practicability of the protection device of the blast furnace tapping runner. The operation of the rotating shaft 4 can drive the frame 41 to rotate and adjust the angle. The operation of the blower 44 driven by one side of the support rod 43 can quickly dissipate heat from the cleaning plate 24, thus facilitating rotation and use, and improving the practicability and protection effect of the protection device of the blast furnace tapping runner.
