At a large flow rate, the landing point of the residual iron molten iron 03 is very easy to overflow to the outside of the tank mouth 011 of the molten iron tank 01. At a small flow rate, the landing point of the residual iron molten iron 03 may also splash outside the tank mouth 011 of the molten iron tank 01, causing the residual iron molten iron 03 to splash and overflow, which may burn the molten iron tank 01, the rails and other facilities belonging to the molten iron tank 01, and cause damage to equipment or personnel.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0031] To solve the above technical problems, Figure 2 and Figure 3 As shown, an embodiment of the utility model provides a device for preventing residual iron and molten iron from splashing out, including a hanging structure 10 and a guide pipe 20, the diameter of the upper port 21 of the guide pipe 20 is larger than the diameter of the tank mouth 011 of the molten iron tank 01, the diameter of the lower port 22 of the guide pipe 20 is smaller than the diameter of the tank mouth 011 of the molten iron tank 01, the hanging structure 10 is connected to the upper port 21 of the guide pipe 20, and the hanging structure 10 is used to hang the guide pipe 20 below the discharge port of the residual iron ditch 02.

[0032] It should be noted that the guide tube 20 is cast from refractory material, and its upper port 21 is the pipe mouth located at the top when in use, and its lower port 22 is the pipe mouth located at the bottom when in use. Preferably, the upper port 21 and the lower port 22 are both circular-mouth structures, and their respective calibers are also their diameters. Of course, under normal circumstances, the tank mouth 011 of the molten iron tank 01 is also a circular-mouth structure, and the caliber of the upper port 21 of the guide tube 20, the caliber of the tank mouth 011 of the molten iron tank 01 and the caliber of the lower port 22 of the guide tube 20 are successively smaller, that is, the inner diameter of the upper port 21, the inner diameter of the tank mouth 022 and the inner diameter of the lower port 22 are successively smaller. It should be understood that the calibers of the upper port 21 and the lower port 22 need to be designed according to the size of the discharge port of the residual iron ditch 02 and the size of the tank mouth 011 of the molten iron tank 01 in actual application, and are not specifically limited here. At the same time, the lifting structure 10 can be a frame, a rod, a chain or other structure, as long as it can be connected to the lifting equipment and can lift the guide pipe 20. In addition, when in use, the lifting structure 10 can be connected to, for example, a gantry car or a crane, and after the upper port 21 of the guide pipe 20 is lifted to below the discharge port of the residual iron ditch 02, the lifting structure 10 can be placed or connected to the platform foundation of the blast furnace ironmaking equipment. It can be understood that in the blast furnace ironmaking setting, for example, the iron-making yard platform is located above the discharge port of the residual iron ditch 02, and the iron-making yard platform can be used as a fixed foundation for the lifting structure 10 during the residual iron molten iron 03 discharge operation. Of course, the lifting structure 10 can be lifted by the lifting equipment for operation. Preferably, during operation, the lifting structure 10 is fixed on the platform foundation, and the structure is more solid and stable, which makes the residual iron molten iron 03 discharge operation more stable and reliable.

[0033] In this embodiment, the device for preventing residual iron and molten iron from splashing out provided in this embodiment can be applied to metallurgical equipment, such as in blast furnace ironmaking, during the operation of discharging residual iron and molten iron 03 from the main ditch of the blast furnace into the molten iron tank 01 through the residual iron ditch 02, by setting a mutually connected hanging structure 10 and a guide pipe 20, the hanging structure 10 can be connected to a hanging device, such as a gantry or a crane, to hang the guide pipe 20 below the discharge port of the residual iron ditch 02, and by The caliber of the upper end 21 of the guide pipe 20, the caliber of the tank opening 011 of the molten iron tank 01 and the caliber of the lower end 22 of the guide pipe 20 are set to be a structural form that is successively smaller, that is, the caliber of the upper end 21 of the guide pipe 20 is larger than the caliber of the tank opening 011 of the molten iron tank 01, and the caliber of the lower end 22 of the guide pipe 20 is smaller than the caliber of the tank opening 011 of the molten iron tank 01. After the upper end 21 of the guide pipe 20 is connected to the hanging structure 10, the upper end 21 of the guide pipe 20 is hung to the drainage of the residual iron ditch 02. Below the discharge port, the lower port 22 of the guide pipe 20 is aligned with the tank mouth 011 of the molten iron tank 01. Compared with the operation form of directly discharging the residual iron and molten iron 03 to the tank mouth 011 of the molten iron tank 01 through the residual iron groove 02 in the prior art, the upper port 21 of the guide pipe 20 is easier to completely converge the residual iron and molten iron 03 into the pipe, that is, to prevent splashing or overflowing. At the same time, by setting the diameter of the lower port 22 of the guide pipe 20 to be smaller than the diameter of the tank mouth 011 of the molten iron tank 01, After the residual iron molten iron 03 enters the guide pipe 20 through the upper port 21 of the guide pipe 20 and then flows out through the lower port 22 of the guide pipe 20, it flows into the tank mouth 011 of the molten iron tank 01 more easily and completely, that is, it is smoothly and reliably discharged into the molten iron tank 01, thereby preventing the residual iron molten iron 03 from splashing or overflowing outside the molten iron tank, effectively protecting the safety of operating equipment and personnel, and at the same time there is no need to overly control and care about the flow rate of the residual iron molten iron 03, thereby improving operating efficiency.

[0034] Alternatively, if Figure 2 and Figure 3 As shown, the guide pipe 20 is a funnel-shaped structure, the upper portion of the guide pipe 20 is an inverted cone-shaped pipe structure, and the lower portion of the guide pipe 20 is a cylindrical straight pipe structure.

[0035] Specifically, the inverted cone tube structure is a tube structure whose tube mouth diameter continuously decreases from top to bottom, and the cylindrical straight tube structure is a vertically arranged straight circular tube structure, and the two are integrally cast and molded to form an overall funnel-shaped structure. When in use, the inverted cone tube structure is located at the top and the cylindrical straight tube structure is vertically arranged, which has a better confluence and splash-proof effect.

[0036] In this embodiment, by setting the guide tube 20 as a funnel-shaped structure, the residual iron molten iron 03 can be better converged and rectified to prevent overflow and splashing. That is, by setting the upper part of the guide tube 20 as an inverted cone tube structure, when the upper port 21 of the guide tube 20 is located below the discharge port of the residual iron ditch 02, it is more convenient and easy to receive the residual iron molten iron 03 and converge it into the lower cylindrical straight tube structure, and the lower part is rectified, that is, the water flow of the residual iron molten iron 03 is constrained and converged into a regular cylindrical shape before being discharged. The water flow is more uniform and regular, and then it enters the tank mouth 011 of the molten iron tank 01 more smoothly and stably, effectively preventing overflow and splashing.

[0037] Alternatively, if Figures 2 to 4 As shown, the hanging structure 10 includes a bracket 11 and a connecting member 12 , one end of the connecting member 12 is connected to the bracket 11 , and the other end of the connecting member 12 is connected to the upper port 21 of the guide pipe 20 .

[0038] Specifically, the connecting member 12 is connected to the lower end of the bracket 11, and the upper end of the bracket 11 is connected to the lifting equipment. The connecting member 12 can be a rod, a rope, a chain structure, etc., which is not specifically limited here.

[0039] In this embodiment, by connecting the bracket 11 and the connecting piece 12 of the lifting structure 10 to each other, and lifting the upper port 21 of the guide tube 20 through the connecting piece 12, on the one hand, the bracket 11 is set for lifting, and the lifting and hoisting process is more stable and reliable. On the other hand, the connecting piece 12 is convenient for disassembly and assembly with the bracket 11 and the guide tube 20, thereby making the overall structure more stable and reliable, and convenient for lifting and disassembly and assembly.

[0040] Alternatively, if Figures 2 to 4 As shown, the number of the connecting members 12 is set to four, and the four connecting points of the four connecting members 12 and the upper port 21 of the flow guide pipe 20 are connected in sequence to form a square.

[0041] It should be noted that the number of the connectors 12 can also be set to other numbers, such as three, five, etc., as long as the guide tube 20 can be stably and reliably suspended. Preferably, for cost and convenience considerations, the number of the connectors 12 is set to four.

[0042] In this embodiment, by setting the number of connecting pieces 12 to four, and by connecting the connecting pieces 12 and the connecting pieces of the upper port 21 of the guide pipe 20 in sequence to form a square arrangement, on the one hand, the four connecting pieces 12 are used to suspend the guide pipe 20, which can prevent the guide pipe 20 from deflecting or rotating during lifting or operation, and the structure is more stable and reliable. On the other hand, by connecting the connecting pieces 12 and the connecting pieces of the upper port 21 of the guide pipe 20 in sequence to form a square arrangement, when in use, the discharge port of the residual iron ditch 02 can extend from any side into the space surrounded by the four connecting pieces 12, that is, it is located above the upper port 21 of the guide pipe 20, which is more convenient to use and will not interfere with the discharge port of the residual iron ditch 02, and the overall use is more stable and convenient.

[0043] Alternatively, if Figures 2 to 4 As shown, the hanging structure 10 further includes a hanger 13 , the bracket 11 is a square frame structure, and four hangers 13 are respectively connected to the four corners of the bracket 11 .

[0044] Specifically, the bracket 11 is a frame structure formed by, for example, welding of I-shaped steels, and has an overall square structure, which is arranged corresponding to the square structure composed of four connecting members 12, so that the structure is more stable and reliable.

[0045] In this embodiment, by setting up a hanger 13, and by setting up the bracket as a square frame structure, and connecting four hangers 13 to the four corners of the bracket 11 respectively, when in use, it can be connected to the lifting equipment through the hanger 13, and the connection is more convenient and stable. At the same time, the bracket 11 with a square frame structure can adapt to the connection structure of four connecting parts 12, thereby further improving the overall stability and reliability during use.

[0046] Alternatively, if Figures 2 to 4 As shown, the hanger 13 includes a lifting ring and a connecting sleeve that are connected to each other. The connecting sleeve is sleeved on the bracket 11, and the lifting ring is used to connect with the lifting equipment.

[0047] Specifically, the connecting sleeve can be configured as a square tube structure adapted to the I-shaped steel structure, and can be directly sleeved thereon, or additional bolt connections or welding can be provided on this basis to improve the firmness and stability of the structure.

[0048] In this embodiment, by configuring the hanger 13 as a structure of mutually connected lifting rings and connecting sleeves, the connecting sleeve can be easily and quickly sleeved on the bracket 11, which is convenient for assembly and adjustment of the connection position. At the same time, the lifting ring is more convenient for connection with lifting equipment such as a lifting rope, and is convenient for disconnection, making the whole more convenient and quick to use.

[0049] Alternatively, if Figure 2 , Figure 3 and Figure 5 As shown, the connecting member 12 is a rod structure, and the upper port 21 of the guide tube 20 is provided with a connecting seat, and the connecting member 12 is fixedly connected to the connecting seat.

[0050] It should be noted that Figure 2 , Figure 3 and Figure 5 The position where the connecting ear 23 is shown can be set as a connecting seat, that is, in another embodiment, the connecting seat can be replaced by the connecting ear 23. Of course, in this embodiment, the connecting ear 23 can be added to the connecting seat.

[0051] In this embodiment, by setting the connecting member 12 as a rod structure, and setting a connecting seat on the upper port 21 of the guide tube 20, and fixing the connecting member 12 to the connecting seat, on the one hand, the connecting member 12 with the rod structure can be more stably and firmly connected to the guide tube 20, and the rod structure is not easy to deform, which can prevent the guide tube 20 from shaking or rotating during lifting or operation to a certain extent, thereby further improving the operation stability. On the other hand, the connecting member 12 is fixedly connected to the connecting seat set on the upper port 21, thereby further improving the structural firmness and making the structure more reliable and stable.

[0052] Alternatively, if Figure 2 and Figure 3 As shown, the connecting member 12 is a chain structure.

[0053] It should be noted that the chain structure can withstand a large vertical pulling force when it is in use, that is, when it is hanging the guide pipe 20. When it is not in operation, the chain structure can be deformed to facilitate recovery and reduce occupied space.

[0054] In this embodiment, by providing the connecting piece 12 with a chain structure, on the one hand, it is more convenient to adjust its connection length and facilitate connection and assembly; on the other hand, when the device is not in use, it is more convenient to recycle. The chain structure is deformable and does not take up space, and has better flexibility.

[0055] Alternatively, if Figure 2 , Figure 3 and Figure 5 As shown, the upper port 21 of the guide tube 20 is provided with a connecting ear 23 , and the connecting ear 23 is detachably connected to the connecting member 12 .

[0056] Specifically, the number of connecting ears 23 corresponds to the number of connecting members 12, for example, four are set, and the four connecting ears 23 are connected in sequence in the plane where the upper port 21 is located to form a square, and its lifting structure is more stable and reliable. At the same time, the detachable connection between the connecting ears 23 and the connecting member 12 can be a buckle and a knot structure of the connecting member 12 with a chain structure and connected to the connecting ears 23, or a pin is inserted into the connecting member 12 with a chain structure and connected to the connecting ears 23, and no specific limitation is made here.

[0057] In this embodiment, by providing a connecting ear 23 at the upper port 21 of the guide tube 20, it is more convenient to connect with the connecting piece 12 of the chain structure, and by detachably connecting the connecting ear 23 to the connecting piece 12, it is convenient to connect and assemble when in use, and it can also be conveniently and quickly disassembled when the device is not in use, so it is convenient to use.

[0061] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
