Description

Technical Field

[0001] The utility model relates to the field of plugging the iron notch of blast furnaces, in particular to a plugging device based on a hydraulic taphole drill of a blast furnace. Background Art

[0002] The operation of plugging the blast furnace notch is a very important link in the front-of-furnace operation. The mechanical equipment used is generally a hydraulic clay gun. Under normal circumstances, after the blast furnace discharges slag and molten iron, the clay gun rotates into place, the center line of the gun nozzle coincides with the center lines of the clay sleeve and the iron notch hole, the gun nozzle fits tightly with the clay sleeve and the iron notch hole. Driven by the clay plug, the gun clay is injected into the iron notch hole. After the gun clay solidifies, the clay gun is withdrawn to complete the plugging operation. During the process of plugging the blast furnace notch, once a failure occurs to the clay gun, the operation of injecting clay cannot be carried out, which will also cause the iron notch to be unable to be plugged. When the iron notch cannot be plugged, it is possible that the molten iron overflows from the ladle and flows onto the railway, and only measures such as reducing the blast or stopping the blast for plugging can be taken, which affects various technical and economic indexes of the blast furnace and even causes fluctuations in the furnace condition.

[0040] As Figure 1 shown, an embodiment of the present invention provides a plugging device based on a blast furnace hydraulic taphole drill, including: a taphole drill 1 and an emergency plugging device 2;

[0041] The emergency plugging device 2 includes: a cylinder body 21 for loading plugging mud;

[0042] One end of the cylinder body 21 is open and connected with a front section 22 of a nozzle for discharging mud, and a mud ramming piston 23 is arranged inside the other end of the cylinder body;

[0043] The cylinder body 21 is connected to the taphole drill 1;

[0044] The outside of the mud ramming piston 23 is connected to the drill pipe 11 of the taphole drill 1.

[0045] The cylinder body 21 of the emergency plugging device 2 is connected to the taphole drill 1, and the mud ramming piston 23 is connected to the drill pipe 11. The front section 22 of the nozzle can be prepared in advance with a variety of models of different specifications and sizes to match the size of the plugging as required. During use, align the front section 22 of the nozzle with the plugging, move the taphole drill 11 in the direction of the plugging, so that the front section 22 of the nozzle is plugged into the plugging, start the trolley on the taphole drill 1, drive the drill pipe 11 to move forward, the drill pipe 11 pushes the mud ramming piston 23, the mud ramming piston 23 pushes the plugging mud in the cylinder body 21, and the plugging mud overflows from the outlet of the front section 22 of the nozzle to plug the plugging.

[0046] The embodiment of the present invention has the following technical effects: By installing an emergency plugging device on the existing taphole drill, during the period when the clay gun fails, the taphole drill equipped with the emergency plugging device can be used in time to replace the clay gun for plugging operations, which is simple, fast and safe. By simulating the situation where the clay gun fails and cannot operate on site, the plugging device based on the blast furnace hydraulic taphole drill is used for temporary plugging operations, which is safe and reliable. After being verified by multiple sites, very ideal results are obtained, greatly reducing the risk of affecting the production safety of the blast furnace due to the failure of the clay gun, and not damaging the structure of the original equipment, with simple structure and small maintenance volume, and is suitable for wide use.

[0047] Furthermore, as Figure 1 shown, the cylinder body 21 is detachably connected to the taphole drill 1.

[0048] It is convenient for emergency installation, disassembly and maintenance.

[0049] Furthermore, as Figure 1 shown, the cylinder block 21 is connected to the front part of the traveling rail 12 of the taphole machine 1 in a detachable connection manner.

[0050] It is convenient for emergency installation, disassembly and maintenance, and makes full use of the original structure of the taphole machine to connect the emergency tuyere blocking device, reducing the modification cost and difficulty.

[0051] Furthermore, as Figure 1 and Figure 3 shown, the emergency tuyere blocking device 2 further includes: a mounting base plate 24 and a pressing plate 25;

[0052] The pressing plate 25 placed above the traveling rail 12 and the mounting base plate 24 placed below the traveling rail 12 are cooperatively connected to clamp the traveling rail 12;

[0053] The lower side surface of the mounting base plate 24 is connected to the cylinder block 21.

[0054] Through the mounting base plate 24 and the pressing plate 25, the structural shape of the traveling rail can be fully utilized, without changing the mechanical structure of the taphole machine. The emergency tuyere blocking device can be directly mounted under the taphole machine, and it is more convenient to connect with the drill pipe.

[0055] Preferably, as Figure 3 shown, the traveling rail is an I-shaped rail, including: an upper flange, a web and a lower flange; the pressing plate 25 presses on the upper side surface of the lower flange of the traveling rail, and the mounting base plate 24 presses on the lower side surface of the lower flange of the traveling rail and is cooperatively clamped and connected with the pressing plate 25.

[0056] Furthermore, the mounting base plate 24 and the pressing plate 25 are connected by a split pin and inclined bolt.

[0057] The split pin and inclined bolt connection not only ensures stable connection, but also is convenient for emergency installation and disassembly, reducing the emergency response time and the overall operation time. When the mud gun fails, it can be processed in time to avoid affecting the production safety and working efficiency of the blast furnace.

[0058] Furthermore, as Figure 1 shown, the mud pumping piston 23 is connected to the drill pipe 11 of the taphole machine 1 in a detachable manner.

[0059] It not only ensures stable connection, but also is convenient for emergency installation and disassembly, reducing the emergency response time and the overall operation time. When the mud gun fails, it can be processed in time to avoid affecting the production safety and working efficiency of the blast furnace.

[0060] Furthermore, as Figure 1As shown, the emergency plugging device 2 further includes: a piston drill rod sleeve 26;

[0061] One end of the piston drill rod sleeve 26 is fixedly connected to the mud pumping piston 23 , and the other end of the piston drill rod sleeve 26 is threadedly connected to the drill rod 11 .

[0062] The mud-beating piston 23 extends the part connected with the drill rod 11 to the outside of the cylinder body 21 through the piston drill rod sleeve 26, which is convenient for connection or disassembly, thereby ensuring a stable connection and facilitating emergency installation and disassembly, reducing emergency response time, reducing overall operation time, and ensuring that when the mud gun fails, it is handled in time to avoid affecting the safety and work efficiency of blast furnace production.

[0063] Furthermore, if Figure 1 As shown, the cylinder body 21 and the front section 22 of the gun nozzle are detachably connected by a round pin.

[0064] The nozzle front section 22 can be prepared in various sizes in advance so as to be used with plugs of different sizes. It is connected to the cylinder body 21 through a round pin, so that it is convenient to replace the nozzle front section 22 of appropriate size according to the plug size in an emergency. It not only ensures stable connection, but also facilitates emergency installation and disassembly, reduces emergency response time, reduces overall operation time, and ensures that when the mud gun fails, it is handled in time to avoid affecting the safety and work efficiency of blast furnace production.

[0065] Furthermore, if Figure 1 As shown, the cylinder body 21 includes: a transition pipe 27 and a mud cylinder 28;

[0066] The nozzle front section 22 is detachably connected to one end of the transition pipe 27 by a round pin;

[0067] The other end of the transition pipe 27 is connected to the mud cylinder 28 by an oblique bolt.

[0068] The cylinder body 21 is divided into two sections and connected by round pins and latch oblique bolts, which can be quickly installed and disassembled, making it convenient to maintain and clean the cylinder body.

[0069] Furthermore, if Figure 1As shown in the figure, the cylinder block 21 includes a transition pipe 27 and a mud cylinder 28; the emergency plugging device 2 further includes a piston drill pipe sleeve 26, a mounting base plate 24 and a pressing plate 25; the mounting base plate 24 has a middle concave structure, and the mounting base plate 24 and the pressing plate 25 are connected by a combination of a pin and a diagonal bolt to fix the emergency plugging device on the gantry crane rail 12; the front section 22 of the nozzle is a hollow frustum cone structure; the front section 22 of the nozzle, the transition pipe 27 and the mud cylinder 28 are hollow structures, and anhydrous gunite is provided inside; the front section 22 of the nozzle and the transition pipe 27 are connected by a round pin; the transition pipe 27 and the mud cylinder 28 are connected by a combination of a pin and a diagonal bolt; one end of the piston drill pipe sleeve 26 is fixedly connected to the mud pushing piston 23, the other end of the piston drill pipe sleeve 26 is threadedly connected to one end of the drill pipe 11, and the other end of the drill pipe 11 is connected to the gantry crane 1.

[0070] Further, as Figure 1 shown, the front section 22 of the nozzle is a hollow frustum cone structure.

[0071] It is convenient to push the gunite into the plugging opening from the cylinder block.

[0072] Further, as Figure 2 shown, a groove 29 running parallel to the rail 12 is provided in the middle of the upper side surface of the mounting base plate 24.

[0073] The gantry crane drives the trolley on the rail through a chain to push the drill pipe to move. The chain will sag due to gravity. The mounting base plate is installed below the rail. By providing the groove 29, it can be avoided that the sagging chain contacts and interferes with the mounting base plate.

[0074] Preferably, as Figure 1 shown, the cylinder block 21 and the drill pipe 11 are coaxial.

[0075] In some embodiments, the cylinder block 21 and the drill pipe 11 can be connected non-coaxially. As long as the drill pipe 11 is connected to the mud pushing piston 23 and can apply a thrust to the mud pushing piston 23, mud pushing can be achieved. However, when they are non-coaxial, there may be a torque between the drill pipe 11 and the mud pushing piston 23, which is not conducive to stable connection. Preferably, the cylinder block 21 and the drill pipe 11 are coaxial, and the thrust of the drill pipe 11 directly acts on the mud pushing piston 23 along the axis, which can provide a complete thrust.

[0076] Further, the gantry crane further includes a gantry crane drill pipe sleeve;

[0077] The gantry crane drill pipe sleeve is fixedly connected to the rear of the gantry crane;

[0078] The drill pipe 11 is threadedly connected to the gantry crane drill pipe sleeve.

[0079] Further, the gantry crane further includes a vibration device;

[0080] The rapping device is drivingly connected to the drill pipe.

[0081] In some embodiments, the rapping device can indirectly drive the drill pipe by driving the trolley on the driving rail to provide rapping. When it is difficult for the front section 22 of the nozzle to extend into the taphole, rapping can be used to help the front section 22 of the nozzle extend into the taphole.
