Description

Technical Field

[0001] The utility model relates to the technical field of pig iron smelting, in particular to a molten iron heat preservation and conveying device. Background Art

[0002] Patent publication number CN215033567U discloses an online molten iron transport hot metal ladle insulation device, comprising a transport vehicle, wherein support seats are fixedly installed on both sides of the top of the transport vehicle, and a first support handle extending to the opposite sides of the two support seats is movably installed inside the support seat, and the first support handle is fixedly connected to the insulation tank at one end away from the support seat, and the hot metal ladle body is fixedly installed inside the insulation tank. The hot metal ladle insulation device for online molten iron transport, through the annular rack provided on the right positioning turntable and the positioning rack provided on the transport vehicle, facilitates the mutual engagement between the annular rack and the positioning rack to stabilize the right positioning turntable, thereby increasing the stability of the insulation tank. At this time, it is convenient for workers to open the insulation cover, thereby allowing the rotating insulation tank to drive the hot metal ladle body to unload the molten iron inside it. This device reduces the difficulty of manual operation and improves work efficiency.

[0003] However, the rotating parts that cause the molten iron ladle to backflow in the above technology not only need to bear the stress when the molten iron ladle backflows, but also need to bear the stress of supporting the molten iron ladle during transportation, resulting in excessive stress on its parts, which can easily cause structural damage in this part. In severe cases, the molten iron ladle may tip over, causing molten metal to overflow, posing a potential safety hazard to the production environment. Utility Model Content

[0004] The purpose of the utility model is to provide a molten iron heat preservation and conveying device.

[0005] The technical problem solved by the utility model is that the stress on the structural components of the prior art that cause the molten metal to be poured back into the molten iron ladle is too large, and the components are extremely easy to be damaged, resulting in a safety hazard during the transportation of the molten iron ladle.

[0006] The utility model can be realized through the following technical scheme: it includes a support frame fixedly installed on the top of the transport vehicle, rotating rods are rotatably installed on both sides of the support frame, a molten iron ladle body capable of feeding and discharging materials is fixedly installed between the two rotating rods, a trigger component for causing the molten iron ladle body to rotate is installed on the transport vehicle, a traction component for supporting the rotation angle of the molten iron ladle body is provided between the molten iron ladle body and the support frame, a lifting frame is slidably installed through the top of the support frame, and a clamping component for clamping, fixing, sealing and insulating the molten iron ladle body in a vertical state is provided at the bottom of the lifting frame.

[0007] The further technical improvement of the utility model is that: a feed port is opened on the top of the molten iron tank body, a discharge nozzle is fixedly connected to one side of the molten iron tank body, and a heat-insulating bottom cover is sleeved on the bottom of the molten iron tank body.

[0008] Furthermore, the trigger assembly includes an arc-shaped rack fixedly installed at the bottom of the molten iron ladle body, and a transmission rack meshing with the arc-shaped rack is slidably installed through the top of the transport vehicle.

[0009] Furthermore, the traction assembly includes a slide plate fixedly installed on the side of the outer peripheral wall of the molten iron ladle body away from the discharge nozzle, a slider 1 is slidably installed on the slide plate, a slider 2 is slidably installed on the side of the support frame adjacent to the slider 1, and a traction rod is rotatably installed between the slider 2 and the slider 1.

[0010] Furthermore, the clamping assembly includes clamping plates that are slidably installed on both rotating rods and are adapted to the outer peripheral wall of the molten iron ladle body. An insulation layer that is adapted to the outer peripheral wall of the molten iron ladle body is fixedly installed on the side of the clamping plate adjacent to the molten iron ladle body. A slide that is slidably connected to one side of the support frame is fixedly installed on the side of the clamping plate away from the molten iron ladle body. Connecting plates are rotatably installed on both sides of the bottom of the lifting frame, and the ends of the two connecting plates away from the lifting frame are respectively rotatably connected to the top side of the two clamping plates.

[0011] Furthermore, a heat-insulating top cover adapted to the feed port is fixedly installed at a position on the bottom of the lifting frame corresponding to the molten iron ladle body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the molten iron ladle body rotates, the present application uses a traction rod to traction and support the molten iron ladle body that is in an inclined state after rotation, and disperses the stress on the rotating axis of the molten iron ladle body to the traction rod, thereby reducing cracks and fractures caused by stress concentration in the rotating parts, thereby reducing the failure rate.

[0014] 2. In the present application, when the molten iron ladle body is kept in a vertical state, the lifting frame drives the thermal insulation top cover to cover the discharge port, while the two clamping plates fix the outer peripheral wall of the molten iron ladle body, and drive the thermal insulation layer to adhere to the outer peripheral wall of the molten iron ladle body through the clamping plates, so as to enhance the thermal insulation performance of the molten iron ladle body, and reduce the impact of the vibration generated when the transport vehicle transports the molten iron ladle body on the molten iron ladle body, thereby preventing the molten metal liquid in the molten iron ladle body from overflowing.

DETAILED DESCRIPTION

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0021] See also Figure 1-3 As shown, this embodiment provides a molten iron insulation conveying device, including a transport vehicle 1, a support frame 2 is fixedly installed on the top of the transport vehicle 1, and rotating rods 3 are rotatably installed on both sides of the support frame 2. A driving motor (not shown in the figure) for driving one of the rotating rods 3 to rotate is installed on the support frame 2, and a molten iron tank body 4 is fixedly installed between the two rotating rods 3. A feed port 5 is opened on the top of the molten iron tank body 4, and a discharge nozzle 6 is fixedly connected to one side of the molten iron tank body 4. An arc-shaped rack 7 is fixedly installed on the bottom of the molten iron tank body 4, and a transmission rack 8 meshing with the arc-shaped rack 7 is slidably installed through the top of the transport vehicle 1. A hydraulic cylinder for driving the transmission rack 8 to move left and right in the horizontal direction is installed on the transport vehicle 1. An insulating bottom cover 9 is provided on the bottom of the molten iron tank body 4 for insulating the bottom of the molten iron tank body 4;

[0022] When the transmission rack 8 moves to the left, it will drive the molten iron ladle body 4 to rotate clockwise under the support of the two rotating rods 3 through the arc-shaped rack 7. When the molten iron ladle body 4 rotates clockwise, the molten metal liquid in the molten iron ladle body 4 will flow to the discharge nozzle 6, thereby discharging from the discharge nozzle 6. Conversely, the molten iron ladle body 4 is rotated counterclockwise, thereby facilitating the return of the molten iron ladle body 4 to a vertical state to prevent the molten metal liquid from overflowing from the discharge nozzle 6.

[0023] A slide plate 10 is fixedly installed between the top of the arc-shaped rack 7 and the molten iron ladle body 4. A slider 11 is slidably installed on the slide plate 10. A slider 2 12 is slidably installed on the side of the support frame 2 adjacent to the slider 11. A traction rod 13 is rotatably installed between the slider 2 12 and the slider 11.

[0024] When the iron ladle body 4 rotates clockwise, the slider 11 will slide along the sliding track of the slide plate 10 toward the bottom of the slide plate 10, and drive the slide bar 2 to slide downward on the support frame 2 through the traction rod 13 until the slider 11 and the slider 2 12 are in the same horizontal plane. When the iron ladle body 4 rotates counterclockwise, the opposite is true. When the iron ladle body 4 stops rotating, the traction rod 13 between the slider 11 and the slider 2 12 can to a certain extent pull and support the inclination angle of the iron ladle body 4, thereby reducing the stress on the rotating part of the iron ladle body 4.

[0025] A lifting frame 14 is slidably installed on the top of the support frame 2, and a cylinder for driving the lifting frame 14 to move up and down is installed on the support frame 2. An insulating top cover 15 that is adapted to the feed port 5 is fixedly installed at the position of the bottom of the lifting frame 14 corresponding to the molten iron ladle body 4. A clamping plate 16 that is adapted to the outer peripheral wall of the molten iron ladle body 4 is slidably installed on the two rotating rods 3. A thermal insulation layer 17 that is adapted to the outer peripheral wall of the molten iron ladle body 4 is fixedly installed on the side of the clamping plate 16 adjacent to the molten iron ladle body 4. A slide plate 18 that is slidably connected to the support frame 2 is fixedly installed on the side of the clamping plate 16 away from the molten iron ladle body 4. Connecting plates 19 are rotatably installed on both sides of the bottom of the lifting frame 14. The ends of the two connecting plates 19 away from the lifting frame 14 are rotatably connected to the top sides of the two clamping plates 16 respectively;

[0026] When the lifting frame 14 drives the insulation top cover 15 to move downward and cover the feed port 5 on the top of the molten iron ladle body 4, the lifting frame 14 will simultaneously push the two clamping plates 16 along the extension direction of the slide plate 18 toward the outer peripheral wall of the molten iron ladle body 4 through the two connecting plates 19, until the two clamping plates 16 drive the two insulation layers 17 to completely wrap the outer peripheral wall of the molten iron ladle body 4, thereby clamping the molten iron ladle body 4 while enhancing the insulation effect of the molten iron ladle body 4.

[0027] When the utility model is in use, first, the transmission rack 8 drives the molten iron ladle body 4 to rotate to a vertical state through the arc-shaped rack 7, and an appropriate amount of molten metal liquid is poured into the molten iron ladle body 4 through the feed port 5 on the top of the molten iron ladle body 4, and then the lifting frame 14 is moved downward until the insulation top cover 15 is buckled at the discharge port on the top of the molten iron ladle body 4, and the two clamping plates 16 drive the insulation layer 17 to wrap the outer peripheral wall of the molten iron ladle body 4, and then the molten iron ladle body 4 is transported to a designated position by the transport vehicle 1. When the molten iron ladle body 4 is transported, the two clamping plates 16 have a certain fixing and clamping effect on the molten iron ladle, preventing the vibration generated during transportation from directly acting on the rotating shaft of the molten iron ladle body 4;

[0028] After the molten iron ladle body 4 is transported to the designated position, the lifting frame 14 is moved upward, so that the lifting frame 14 drives the insulation top cover 15 to separate from the top discharge port of the molten iron ladle body 4, and drives the two clamping plates 16 to separate from the clamping of the outer peripheral wall of the molten iron ladle body 4, and then moves the transmission rack 8 to the left, so that it drives the molten iron ladle body 4 to rotate clockwise with the rotating rod 3 as the rotating axis through the arc rack 7. While the molten iron ladle body 4 rotates, the traction rod 13 has a certain traction and support effect on it, preventing the molten metal liquid from flowing to one side of the molten iron ladle body 4 after the molten iron ladle body 4 rotates, resulting in an increase in the gravity on this side of the molten iron ladle body 4, thereby increasing the stress at the rotating axis of the molten iron ladle body 4. After the molten metal liquid in the molten iron ladle body 4 is poured out, the transmission rack 8 is moved to the right again, so that it drives the molten iron ladle body 4 to rotate back to a vertical state through the arc rack 7 for subsequent use.

[0029] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
