Description

Technical Field

[0001] This utility model relates to the field of steel casting technology, and in particular to an anti-splash tilting ladle for molten iron. Background Technology

[0002] The casting process requires metal smelting. With continuous development in recent years, my country's steelmaking technology has been continuously improving. Ladles are used for pouring operations in foundry workshops. They receive molten iron in front of the furnace and are then transported by crane to the mold for pouring. When receiving molten iron, existing ladles do not have anti-overflow troughs, making it easy for molten iron to overflow. After the molten iron is poured, during the time from the blast furnace tapping point in the ironmaking plant to the steelmaking workshop waiting to be poured into the converter, the existing empty ladles operate with their openings open, which increases the heat dissipation area many times over and makes heat loss more serious. When receiving molten iron, some ladle linings have already turned black, and the molten iron that remains has solidified, which corrodes the ladle lining and reduces its lifespan.

[0003] According to the announcement number CN209465681U, a molten iron ladle includes a hook, a crossbeam fixedly connected to the bottom of the hook, columns fixedly connected to both sides of the crossbeam, a ladle shaft rotatably connected to the bottom of the columns, a handle provided on the side wall of the columns, a rotating shaft fixedly connected to the axis of the handle, and a worm gear reducer rotatably connected to the handle via the rotating shaft. The worm gear reducer is fixedly connected to the columns, and the handle drives the ladle shaft to rotate via the worm gear reducer. This utility model relates to the field of iron and steel smelting technology. This molten iron ladle achieves the purpose of reducing molten iron overflow and corrosion during the molten iron receiving process, thus improving the service life of the molten iron ladle. Furthermore, when the molten iron ladle is idle, an insulation cover can be added to its top to reduce heat loss and prevent molten iron from solidifying and corroding the ladle lining, thereby improving the efficiency of molten iron transportation and meeting production needs.

[0004] However, the aforementioned patent uses a combination of double hydraulic telescopic rods, lifting rods, and rotating frames to drive the ladle cover, resulting in a very limited lifting stroke. This makes the ladle cover's upward space very short, which is inconvenient for pouring molten iron and transporting molten iron into the ladle.

[0005] To address this issue, a splash-proof tilting ladle for molten iron is proposed, which has the advantages of preventing splashing and reducing heat loss from molten iron, thereby solving the problems mentioned in the background technology. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-splash tilting ladle for molten iron.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a splash-proof tilting ladle, comprising a ladle body and a movable frame surrounding it, wherein the ladle body is disposed inside the movable frame, and a side column is fixedly installed on both the left and right sides of the ladle body; a liquid outlet is disposed on the upper side of the ladle body; a first motor is fixedly installed on the right side of the movable frame by bolts, and the output end of the first motor is fixedly connected to the side column on the right side of the ladle body; a splash-proof frame is welded to the top of the movable frame, and a side box is welded to the left side of the splash-proof frame; the top of the side box is open to... A second motor is fixedly installed with bolts. The output end of the second motor is fixedly connected to a screw rod through the side box. A cover plate is provided on the upper inner side of the splash guard, and the cover plate is directly above the main body of the molten iron ladle. A liquid nozzle cover plate is welded to the edge of the bottom surface of the cover plate corresponding to the liquid outlet. A left support block is welded to the left side of the cover plate, and a threaded sleeve is fixed to the left support block. The threaded sleeve passes through the side box and is threadedly connected to the screw rod. A right support block is welded to the right side of the cover plate, and a dovetail slider is fixed to the end face of the right support block. A dovetail groove is opened on the inner wall of the splash guard, and the dovetail slider is slidably connected to the dovetail groove.

[0008] As a further description of the above technical solution: both the left and right sides of the movable frame are threaded with a threaded post, and the part of the threaded post extending to the inner side of the movable frame is connected to an arc clamp through a bearing seat. The convex surface of the arc clamp is welded with a hand handle, and the concave surface of the arc clamp faces the lower side of the molten iron ladle body.

[0009] As a further description of the above technical solution: a strip-shaped clearance opening is provided between the side box and the splash guard corresponding to the left support block.

[0010] As a further description of the above technical solution: the end face of the liquid outlet is provided with a beveled surface, the liquid outlet cover is inclined about the cover plate, and the inclination angle of the liquid outlet cover is adapted to the beveled surface of the liquid outlet.

[0011] As a further description of the above technical solution: the bottom surface of the cover plate is provided with a circular boss corresponding to the opening on the top surface of the molten iron ladle body.

[0012] As a further description of the above technical solution: the side column on the left side of the molten iron ladle body is connected to the inner wall of the moving frame through a bearing seat.

[0013] As a further description of the above technical solution: the bottom surface of the liquid nozzle cover is welded with an arc-shaped protrusion corresponding to the liquid outlet.

[0014] This utility model has the following beneficial effects: In this invention, a splash guard, side box, and cover plate are installed on the top surface of the movable frame corresponding to the ladle body. By starting the second motor of the side box, the second motor drives the screw fixed at its output end to rotate. As the threaded sleeve moves along the surface of the screw, the cover plate is moved down by the left support block. The right support block slides along the dovetail groove opened on the inner wall of the splash guard through the dovetail slider, so that the cover plate is in contact with the top surface of the ladle body, and the liquid nozzle cover plate welded at an inclination on the bottom surface of the cover plate is in contact with the liquid outlet, thus achieving the sealing of the top opening of the ladle body and the liquid outlet. Compared with the existing ladle, it can minimize the heat loss of molten iron in the ladle body. The use of screw lifting method extends the lifting stroke of the cover plate, thereby preventing interference caused by the tilting of the cover plate and the ladle. In this invention, a set of threaded columns, an arc clamp, and a hand lever are respectively arranged on the left and right sides of the movable frame. Since a bearing seat is provided between the threaded columns and the arc clamp, the two can rotate relative to each other. By rotating the threaded columns of the movable frame and adjusting the inclination of the arc clamp by the hand lever, the threaded columns push the arc clamp closer to the molten iron ladle body, so that the concave surface of the arc clamp abuts against the side of the molten iron ladle body. This achieves clamping and fixing of the molten iron ladle body in a vertical or inclined state, which can maintain the reliability of the molten iron ladle body in a vertical or inclined state, prevent it from slipping and resetting, and facilitate the stable transfer and cleaning of the molten iron ladle body.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] According to an embodiment of the present invention, a splash-proof tilting ladle for molten iron is provided.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a splash-proof tilting ladle according to an embodiment of the present invention includes a ladle body 2 and a movable frame 1 arranged around it. The ladle body 2 is arranged inside the movable frame 1, and a side column 6 is fixedly installed on both the left and right sides of the ladle body 2. A liquid outlet 5 is arranged on the upper side of the ladle body 2. A first motor 4 is fixedly installed on the right side of the movable frame 1 by bolts, and the output end of the first motor 4 is fixedly connected to the side column 6 on the right side of the ladle body 2. A splash-proof frame 3 is welded to the top of the movable frame 1, and a side box 14 is welded to the left side of the splash-proof frame 3. A second motor 16 is fixedly installed on the top of the side box 14 by bolts. A screw 15 is fixedly connected to the output end of the second motor 16 through the side box 14. A cover plate 10 is arranged on the upper inner side of the splash-proof frame 3, and the cover plate 10 is located directly above the ladle body 2. A liquid outlet cover plate 11 is welded to the edge of the bottom surface of the cover plate 10 corresponding to the liquid outlet 5. A left support block 1 is welded to the left side of the cover plate 10. 7. The left support block 17 is fixedly connected with a threaded sleeve 18, which passes through the side box 14 and is threadedly connected to the screw 15. The right support block 12 is welded to the right side of the cover plate 10, and the end face of the right support block 12 is fixedly connected with a dovetail slider 19. The inner wall of the splash guard 3 is provided with a dovetail groove 13, and the dovetail slider 19 is slidably connected to the dovetail groove 13. In this patent, we only use the first motor 4 and the second motor 16 without improving their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method can be adjusted and operated according to the requirements of their instruction manual. They will not be described in detail here. The first motor 4 and the second motor 16 are both equipped with their matching motor controllers. The installation position of the motor controllers is selected according to the actual use requirements to facilitate the operation and control by the operator. In order to facilitate the movement of the mobile frame 1, several moving wheels are also provided at the bottom of the mobile frame 1. In one embodiment, a threaded post 7 is threadedly connected to both the left and right sides of the movable frame 1, and the portion of the threaded post 7 extending to the inner side of the movable frame 1 is connected to an arc clamp 8 via a bearing seat. A hand handle 9 is welded to the convex surface of the arc clamp 8, and the concave surface of the arc clamp 8 faces the lower side of the ladle body 2. Since a bearing seat is provided between the threaded post 7 and the arc clamp 8, they can rotate relative to each other. By rotating the threaded post 7 of the movable frame 1 and adjusting the inclination of the arc clamp 8 via the hand handle 9, the threaded post 7 pushes the arc clamp 8 closer to the ladle body 2, so that the concave surface of the arc clamp 8 abuts against the side of the ladle body 2, thereby achieving clamping and fixing of the ladle body 2 in a vertical or inclined state. This maintains the reliability of the ladle body 2 in a vertical or inclined state and prevents it from slipping and resetting. Clamping the ladle body 2 in a vertical state is mainly used to prevent the molten iron from overturning, while clamping the ladle body 2 in an inclined state is mainly used to facilitate cleaning and maintenance of the ladle body 2.

[0020] In one embodiment, a strip-shaped clearance opening is provided between the side box 14 and the splash guard 3 corresponding to the left support block 17, so that the left support block 17 can move.

[0021] In one embodiment, the end face of the outlet nozzle 5 is provided with a beveled surface, and the nozzle cover 11 is inclined about the cover plate 10. The inclination angle of the nozzle cover 11 is adapted to the beveled surface of the outlet nozzle 5. By setting the nozzle cover 11, the sealing effect of the outlet nozzle 5 on the ladle body 2 can be increased in the prior art, further reducing heat loss or preventing the phenomenon of molten iron splashing.

[0022] In one embodiment, a circular boss is provided on the bottom surface of the cover plate 10 corresponding to the opening on the top surface of the ladle body 2. The circular boss helps to maintain the tight connection between the cover plate 10 and the opening on the top surface of the ladle body 2, thereby reducing heat loss.

[0023] In one embodiment, the side column 6 on the left side of the ladle body 2 is connected to the inner wall of the moving frame 1 through a bearing seat. The side column 6 of the ladle body 2 allows the ladle body 2 and the moving frame 1 to rotate relative to each other. Combined with the setting of the first motor 4, this allows the ladle body 2 to tilt, facilitating the discharge of molten iron.

[0024] In one embodiment, the bottom surface of the nozzle cover 11 is welded with an arc-shaped protrusion corresponding to the nozzle 5. The arc-shaped protrusion helps to maintain the tight connection between the nozzle cover 11 and the nozzle 5, which is beneficial to prevent heat loss.

[0025] Working principle: In use, molten iron is first transferred into the ladle body 2. When the ladle body 2 is splash-proof, the second motor 16 of the side box 14 is activated, causing the second motor 16 to drive the screw 15 fixed at its output end to rotate. As the threaded sleeve 18 moves along the surface of the screw 15, the cover plate 10 is moved down by the left support block 17. The right support block 12 slides along the dovetail groove 13 opened on the inner wall of the splash shield 3 via the dovetail slider 19, so that the cover plate 10 is in contact with the top surface of the ladle body 2, and the liquid nozzle cover 11, which is inclinedly welded to the bottom surface of the cover plate 10, is in contact with the liquid outlet 5. This achieves the sealing of the top opening of the ladle body 2 and the liquid outlet 5, preventing molten iron from splashing during the transfer of the ladle body 2. When pouring molten iron, the second motor 16 is started in reverse to disengage the cover plate 10 and the liquid nozzle cover 11 from the molten iron ladle body 2. When it is necessary to clamp the molten iron ladle body 2, the bearing seat between the threaded column 7 and the arc clamp 8 allows them to rotate relative to each other. By rotating the threaded column 7 of the moving frame 1 and adjusting the inclination of the arc clamp 8 by the hand lever 9, the threaded column 7 pushes the arc clamp 8 closer to the molten iron ladle body 2, so that the concave surface of the arc clamp 8 abuts against the side of the molten iron ladle body 2, thereby achieving clamping and fixing of the molten iron ladle body 2 in a vertical or inclined state. This maintains the reliability of the molten iron ladle body 2 in a vertical or inclined state and prevents it from slipping and resetting.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
