Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1 As shown;

[0024] A blast furnace taphole anti-blocking device comprises a blast furnace main body 1.

[0025] In this embodiment: after molten iron is smelted in a blast furnace, the smelted molten iron is often discharged out of the blast furnace through the taphole. The newly smelted molten iron is mixed with residue. In the process of passing through the taphole, the molten iron is often blocked at the taphole due to the residue or the temperature drop. In order to solve this technical problem, an anti-blocking component 2 and a pushing component 3 are added on this basis.

[0026] More specifically:

[0027] like Figures 1 to 4 As shown:

[0028] In combination with the above content: it also includes an anti-blocking component 2 arranged on the surface of the blast furnace body 1;

[0029] The anti-blocking component 2 includes an iron outlet pipe 21 fixedly connected to the surface of the blast furnace body 1, and the inner side of the iron outlet pipe 21 is fixedly connected to the mounting frame 23, and the inner side of the mounting frame 23 is rotatably connected to a rotating rod 27, and one end of the rotating rod 27 passes through the surface of the mounting frame 23 and is fixedly connected to a spiral blade 28 arranged below the mounting frame 23, and the surface of the rotating rod 27 is fixedly connected to a bevel gear 1 29, and a motor 1 212 is installed on the surface of the iron outlet pipe 21, and the output shaft of the motor 1 212 is fixedly connected to a transmission shaft 211, and the transmission shaft 211 passes through the surface of the iron outlet pipe 21 and extends to the interior of the mounting frame 23 and is connected to a bevel gear 2 210 arranged inside the mounting frame 23, and the bevel gear 1 29 and the bevel gear 2 210 are meshed, and the lower end of the iron outlet pipe 21 is fixedly connected to a hopper 24, and the end of the hopper 24 away from the iron outlet pipe 21 is fixedly connected to a transfer pipe 25, and the opening of the transfer pipe 25 is fixedly connected to an iron outlet 26.

[0030] In this embodiment: since an iron outlet pipe 21 is provided on the surface of the blast furnace body 1, when the staff discharges molten iron from the blast furnace body 1, they can start the motor 1 212, and the output shaft of the motor 1 212 rotates, and through the cooperation between the transmission shaft 211 and the bevel gear 1 29 and the bevel gear 2 210, the effect of driving the rotating rod 27 to rotate is achieved. The rotation of the rotating rod 27 causes the spiral blade 28 to rotate, and the rotation of the spiral blade 28 prevents the molten iron from being blocked.

[0031] It should be noted that: the interior of the mounting frame 23 and the inner surface of the iron outlet pipe 21 are both provided with high temperature resistant ceramic sheets to prevent the metal parts from being affected by excessive temperature.

[0032] Going further:

[0033] In an optional embodiment, four mounting plates 22 are fixedly connected to the surface of the iron tapping pipe 21 , and each mounting plate 22 is connected to the blast furnace body 1 via bolts.

[0034] In this embodiment, since the mounting plate 22 is connected to the blast furnace body 1 by bolts, this design can make the connection of the iron tapping pipe 21 to the surface of the blast furnace body 1 more stable.

[0035] Going further:

[0036] In an optional embodiment, three openings are formed on the surface of the transfer pipe 25 .

[0037] In this embodiment, since three openings are provided on the surface of the transfer pipe 25, this design further facilitates the discharge of molten iron.

[0038] It should be noted that among the three openings of the transfer pipe 25 , the surfaces of two of the openings are respectively provided with a hopper 24 and an iron outlet 26 .

[0039] Going further:

[0040] In an optional embodiment, it further includes a pushing component 3 disposed on the surface of the transfer pipe 25;

[0041] The pushing assembly 3 includes a driving box 31 fixedly connected to the surface of the transfer pipe 25, and a motor 2 32 is installed on the surface of the driving box 31. The output shaft of the motor 2 32 is fixedly connected to the rotating column 33, and the surface of the rotating column 33 is fixedly connected to the cam 34. The inner side of the driving box 31 is slidably connected to the baffle 35, and the side of the baffle 35 away from the cam 34 is fixedly connected to the connecting column 36, and the side of the connecting column 36 away from the baffle 35 is fixedly connected to the pushing block 37. The surface of the transfer pipe 25 is provided with a square groove, and the pushing block 37 is arranged in the square groove and is slidably connected to the transfer pipe 25 through the square groove. A sliding groove is provided on the inner surface of the driving box 31, and both sides of the pushing block 37 are fixedly connected to the sliding block 38. The sliding block 38 is slidably connected to the driving box 31 through the sliding groove, and is slidably connected to the guide rod 39 provided in the sliding groove. The guide rod 39 is fixedly connected to the driving box 31 through the sliding groove, and the surface of the guide rod 39 is wound with a spring, and the two ends of the spring are respectively fixedly connected to the driving box 31 and the sliding block 38.

[0042] In this embodiment: since a drive box 31 is provided on the surface of the transfer pipe 25, the staff can start the second motor 32, and the second motor 32 rotates through the rotating column 33 to drive the cam 34 to rotate, and the rotation of the cam 34 pushes the baffle 35 to move, and the baffle 35 moves through the connecting column 36 to drive the push block 37 to move in the transfer pipe 25. During this process, the push block 37 is limited by the cooperation of the slider 38 and the guide rod 39, and is reset by the spring provided on the surface of the guide rod 39, thereby completing the repeated movement.

[0043] It should be noted that the push block 37 is in contact with the surface of the transfer pipe 25 .

[0044] Working principle: Since the surface of the blast furnace body 1 is provided with an iron tapping pipe 21, when the staff discharges molten iron from the blast furnace body 1, they can start the motor 1 212, and the output shaft of the motor 1 212 rotates, and through the cooperation between the transmission shaft 211 and the bevel gear 1 29 and the bevel gear 2 210, the effect of driving the rotating rod 27 to rotate is achieved. The rotation of the rotating rod 27 causes the spiral blade 28 to rotate, and the rotation of the spiral blade 28 prevents the molten iron from being blocked. Since the mounting plate 22 is connected to the blast furnace body 1 by bolts, this design can make the iron tapping pipe 21 more stably connected to the surface of the blast furnace body 1. Because there are three openings on the surface of the transfer pipe 25, this design further facilitates the discharge of molten iron. Because a drive box 31 is provided on the surface of the transfer pipe 25, the staff can start motor 2 32, and motor 2 32 rotates through the rotating column 33 to drive the cam 34 to rotate. The rotation of the cam 34 pushes the baffle 35 to move. The baffle 35 moves through the connecting column 36 to drive the push block 37 to move in the transfer pipe 25. During this process, the push block 37 is limited by the cooperation of the slider 38 and the guide rod 39, and is reset by the spring provided on the surface of the guide rod 39, thereby completing the repeated movement.
