Description

Technical Field

[0001] This utility model belongs to the field of steelmaking technology, specifically relating to a slag basin for steelmaking. Background Technology

[0002] Slag pots for steelmaking are containers used to hold high-temperature steel slag during the steelmaking process. The temperature of steel slag during steelmaking can reach 1500℃-1700℃. When a large amount of steel slag is piled up at the bottom of the slag pot's inner cavity, the steel slag at the bottom is compressed due to the large amount of steel slag piled up above, causing the bottom area of ​​the slag to cool down slowly. This results in the bottom of the slag pot's inner cavity being in a state of prolonged high temperature and slow heat dissipation. Prolonged contact with high-temperature steel slag will cause severe thermal erosion of the inner wall of the slag pot, leading to changes in the material's microstructure and reduced strength. It may also cause the steel slag to stick to the bottom of the slag pot, adversely affecting the subsequent use of the slag pot. Utility Model Content

[0003] This utility model provides a slag basin for steelmaking, which can assist in heat dissipation at the bottom of the slag basin during use, and prevent the slag in the lower part of the inner cavity of the slag basin from sticking to the inner wall of the slag basin due to slow heat dissipation at high temperature, which would have an adverse effect on the subsequent use of the slag basin.

[0019] Please see Figures 1-4 This utility model provides the following technical solution: a slag basin for steelmaking, including a mounting frame 1, with a steel slag basin 2 rotatably connected inside the mounting frame 1 via a connecting shaft 11. A first transmission shaft 12 is rotatably connected to one side of the mounting frame 1, and one end of the first transmission shaft 12 is fixedly connected to one of the connecting shafts 11. A mounting frame 3 is provided below the mounting frame 1, and a mounting chamber 31 is opened inside the mounting frame 3. A transmission gear shaft 33 is rotatably connected inside the mounting chamber 31, and connecting rods 331 are fixedly connected to both ends of the transmission gear shaft 33. One end of 331 extends to the outside of the mounting frame 3. The outer end of the connecting rod 331 is fixedly connected to the second drive shaft 332. A drive belt 121 is installed between the second drive shaft 332 and the first drive shaft 12. Extension plates 4 are symmetrically slidably connected on both sides of the top of the mounting frame 3. A connecting plate 41 is fixedly connected between the two extension plates 4. Several drive racks 411 are fixedly connected to the bottom of the connecting plate 41. The connecting plate 41 meshes with the drive shaft 33 through several drive racks 411. A cooling fan 5 is fixedly connected to the top of the connecting plate 41.

[0020] In this implementation scheme: the mounting frame 1 provides a carrier for the steel slag basin 2, and the steel slag basin 2 is installed inside the mounting frame 1 by rotation. This allows the steel slag inside the basin 2 to be tilted downwards to pour out the steel slag when it contains a large amount. The steel slag basin 2 provides temporary storage space for steel slag during steelmaking. The mounting frame 3 located below the mounting frame 1 provides a carrier for connecting the transmission gear shaft 33 and the extension plate 4. The extension plate 4 provides a carrier for connecting the connecting plate 41. The transmission gear shaft 33, with the cooperation of the connecting rod 331 and the second transmission shaft 332, forms a transmission assembly that drives the connecting plate 41 to move to one side. The second transmission shaft 332, with the cooperation of the transmission belt 121 and the first transmission shaft 12, is a transmission assembly that can synchronously drive the second transmission shaft 332 to rotate during the rotation of the steel slag basin 2. The cooling fan located on top of the extension plate 4... 5 is used to assist in the heat dissipation of the steel slag basin 2, preventing the steel slag placed at the bottom of the inner cavity of the steel slag basin 2 from sticking together due to slow heat dissipation, which would adversely affect the subsequent use of the steel slag basin 2. At this time, when the steel slag basin 2 rotates, it can synchronously drive the first drive shaft 12 to rotate. At this time, the first drive shaft 12 drives the second drive shaft 332 to rotate synchronously through the drive belt 121. During the rotation of the second drive shaft 332, it can drive the drive gear shaft 33 to rotate. Since the drive gear shaft 33 and the connecting plate 41 are meshed through the drive rack 411, the connecting plate 41 can move to one side during the rotation of the drive gear shaft 33, thereby adjusting the position of the cooling fan 5. This allows the cooling fan 5 to be removed from under the steel slag basin 2 when the steel slag basin 2 is turned over, avoiding interference from the cooling fan 5 when the steel slag basin 2 is poured out.

[0021] The bottom of the mounting frame 1 is provided with a discharge trough 13, and the position of the discharge trough 13 corresponds to the position of the cooling fan 5; wherein the discharge trough 13 is used to provide space for the steel slag in the steel slag basin 2 to be poured outward.

[0022] Both sides of the mounting frame 1 are fixedly connected to support frames 14; the support frames 14 are used to provide support for the mounting frame 1 and are the support components for the entire slag basin.

[0023] Slide rails 32 are fixedly connected to both sides of the top of the mounting frame 3, and the extension plate 4 is slidably connected to the mounting frame 3 via the slide rails 32; wherein the slide rails 32 are used to provide a carrier for the connection between the extension plate 4 and the mounting frame 3.

[0024] A drive motor 6 is fixedly connected to one side of the mounting bracket 1, and the output end of the drive motor 6 is fixedly connected to one of the connecting shafts 11; the drive motor 6 is used to drive the steel slag basin 2 to rotate.

[0025] The mounting frame 3 has symmetrical through slots 34 inside, and one end of the connecting rod 331 passes through the through slots 34 to the outside of the mounting frame 3; wherein the through slots 34 are used to provide space for the connecting rod 331 to pass through.

[0026] A control panel 15 is fixedly connected to one side of the mounting bracket 1, and the control panel 15 is connected to the cooling fan 5 and the drive motor 6 through a connecting cable; the control panel 15 is used to adjust the operation of the drive motor 6 and the cooling fan 5.

[0027] A connecting frame 141 is fixedly connected between the lower end of the support frame 14 and the outer side of the mounting frame 3, and a support plate 35 is fixedly fixed at the bottom of the mounting frame 3; wherein the connecting frame 141 is used to provide a carrier for connecting the mounting frame 3 and the support frame 14, and the support plate 35 is used to provide support for the bottom of the mounting frame 3.

[0028] The working principle and usage process of this utility model are as follows: During the use of this slag basin, the steel slag basin 2 is used to temporarily store steel slag. When the steel slag in the steel slag basin 2 needs to be cleaned, the steel slag basin 2 can be flipped by turning on the drive motor 6. When the steel slag basin 2 is rotating, it can synchronously drive the first drive shaft 12 to rotate. At this time, the first drive shaft 12 drives the second drive shaft 332 to rotate synchronously through the drive belt 121. During the rotation of the second drive shaft 332, it can drive the drive gear shaft 33 to rotate. Since the drive gear shaft 33 and the connecting plate 41 are meshed through the drive rack 411, the connecting plate 41 can move to one side during the rotation of the drive gear shaft 33, thereby adjusting the position of the cooling fan 5. This allows the cooling fan 5 to be removed from under the steel slag basin 2 when the steel slag basin 2 is flipped, avoiding interference from the cooling fan 5 when the steel slag basin 2 is dumped.
