Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing water jackets for iron mixing furnaces, in particular to a water jacket for iron mixing furnaces. Background Art

[0002] The first process of sending molten iron from the ironworks to the steelworks is to add it to the mixing furnace, and the mixing furnace water jacket receives the molten iron. In order to prevent the bottom of the mixing furnace water jacket from being damaged by the high-temperature molten iron for a long time, a water collecting tank 11 is usually installed on the mixing furnace water jacket, and cooling water is added to the water collecting tank to cool the molten iron.

[0003] like Figure 1 As shown, it is a cross-sectional view of a water jacket of a prior art mixing furnace. The water jacket of the prior art mixing furnace comprises a water collecting tank 11, a bottom plate 12, a molten iron receiving body 13, a water inlet pipe 4 and a water outlet. The water collecting tank 11 is located at the periphery of the molten iron receiving body 13, the bottom plate 12 is fixedly connected to the bottom of the water collecting tank 11 and the bottom of the molten iron receiving body 13, a water outlet is provided at the top of the outer wall of the water collecting tank 11, and one end of the water inlet pipe 4 passes through the top of the outer wall of the water collecting tank 11 and extends to the bottom of the water collecting tank 11.

[0004] When the water jacket of the mixing furnace of this structure is in use, molten iron is poured into the molten iron receiving body 13, and water is injected into the water collecting box 11 through the water inlet pipe 4, and the water flow surrounds the outer periphery of the molten iron receiving body 13 to cool the molten iron. With the continuous injection of the water flow, the water in the water collecting box 11 continues to increase, and the water flow in the water collecting box 11 is discharged from the water collecting box 11 through the water outlet. However, under this structure, the water at the bottom of the water collecting box 11 cannot be circulated and discharged from the water collecting box 11, resulting in the water at the bottom of the water collecting box 11 continuously absorbing heat and always concentrating at the bottom of the water collecting box 11, and the cooling effect on the bottom of the water collecting box 11 is not good, and it is still easy to cause the bottom plate 12 to be seriously aged due to high temperature erosion, and it is easy to cause water leakage at the bottom of the mixing furnace water jacket, and the staff needs to replace the bottom plate 12 regularly. During the replacement of the bottom plate 12, not only the normal production of the production workshop is seriously affected, but also there are certain safety hazards. Utility Model Content

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figures 2 to 7 As shown, the utility model provides a water jacket for a mixed iron furnace, comprising a water jacket body 1, a partition 2, a blocking plate 3, a water inlet pipe 4 and a water outlet pipe 5; the water jacket body 1 comprises a water collecting box 11, a bottom plate 12 and a molten iron receiving body 13, the water collecting box 11 is located at the periphery of the molten iron receiving body 13, the bottom plate 12 is connected to the bottom of the water collecting box 11 and the molten iron receiving body 13; the partition 2 is in the shape of an unsealed circular ring, the inner side of the partition 2 is fixedly connected to the outer wall of the molten iron receiving body 13, the outer side of the partition 2 is fixedly connected to the inner wall of the water collecting box 11, the water collecting box 11 is divided into an upper water collecting box 111 and a lower water collecting box 112 by the partition 2, the upper water collecting box 111 and the lower water collecting box 112 are communicated through the unsealed part of the partition 2, the top of the outer wall of the upper water collecting box 111 is provided with a first through hole and a second through hole, the blocking plate 3 is vertically It is directly fixed in the lower water collecting tank 112, the top of the blocking plate 3 is connected to the lower surface of the partition 2, and there is a gap between the bottom of the blocking plate 3 and the upper surface of the bottom plate 12, and the two side edges of the blocking plate 3 are respectively connected to the inner wall of the lower water collecting tank 112 and the outer wall of the molten iron receiving body 13, the outlet pipe 5 is connected to the top of the outer wall of the upper water collecting tank 111 and is located at the periphery of the first through hole, and the outlet pipe 5 is communicated with the interior of the upper water collecting tank 111 through the first through hole; the third through hole 21 is opened on the partition 2, and the third through hole 21 is located at the connection between the partition 2 and the blocking plate 3 and away from the side of the unsealed part, one end of the water inlet pipe 4 passes through the second through hole, the upper water collecting tank 111, and the third through hole 21 in sequence and then extends to the lower water collecting tank 112, and the other end of the water inlet pipe 4 is located at the periphery of the second through hole.

[0027] Specifically, the width of the unsealed portion of the partition plate 2 in the utility model is 100 mm, and the diameter of the third through hole 21 is 57 mm. The materials used for the water collecting tank 11, the molten iron receiving body 13, the bottom plate 12, the partition plate 2 and the plugging plate 3 in the utility model are all Q355B steel. The thickness of the bottom plate 12 in the utility model is 20 mm, and the thickness of the water collecting tank 11, the molten iron receiving body 13, the partition plate 2 and the plugging plate 3 are all 10 mm. The diameter of the water inlet pipe 4 in the utility model is 57 mm, and the diameter of the water outlet pipe 5 is 76 mm.

[0028] Furthermore, in the utility model, the partition plate 2 is fixedly connected at a position 100 mm above the bottom plate 12, the height of the blocking plate 3 is 90 mm, and the height of the gap between the bottom of the blocking plate 3 and the upper surface of the bottom plate 12 is 10 mm.

[0029] In a specific implementation manner, when an external water source continuously injects water through the water inlet pipe 4, the water flows along the water inlet pipe 4 to reach the lower water collecting tank 112. Due to the partitioning effect of the blocking plate 3 on the lower water collecting tank 112, the water flow in the lower water collecting tank 112 can enter the upper water collecting tank 111 from the unsealed portion of the partition 2, thereby realizing the water flow circulation of the lower water collecting tank 112; the water inlet pipe 4 is located at the connection between the partition 2 and the blocking plate 3 and away from the unsealed side, so that the starting point and the end point of the water flow in the lower water collecting tank 112 are as close as possible, thereby realizing the lower water collecting tank 112 to the greatest extent. The water circulates in the water tank 112; the water flows from the lower water collecting tank 112 into the upper water collecting tank 111, and is discharged through the outlet pipe 5 connected to the upper water collecting tank 111, thereby completing the water circulation between the lower water collecting tank 112 and the upper water collecting tank 111; since the water flow injected from the external water source is ordinary tap water, there may be impurities in the water flow. Through the gap between the blocking plate 3 and the bottom plate 12, the impurities can circulate together with the circulation of the water flow in the lower water collecting tank 112, thereby avoiding stagnation and accumulation of impurities in the lower water collecting tank 112.

[0030] Through the iron mixing furnace water jacket provided by the utility model, the water flow located at the bottom of the water collecting box 11 absorbs the heat of the bottom plate 12 and can be discharged outside the water collecting box 11 through water circulation, thereby enhancing the cooling effect on the bottom plate 12, extending the service life of the bottom plate 12, reducing the maintenance cost of the water jacket body 1, ensuring the normal production of the production workshop, and greatly reducing the safety hazards caused by water leakage of the bottom plate 12.

[0031] Optionally, a water jacket of a mixing iron furnace also includes two reinforcing plates 6, the first reinforcing plate 6 is sleeved on the outer periphery of the other end of the water inlet pipe 4, and one side of the first reinforcing plate 6 is fixedly connected to the outer wall of the upper water collecting tank 111; the second reinforcing plate 6 is sleeved on the outer periphery of the water outlet pipe 5, and one side of the second reinforcing plate 6 is fixedly connected to the outer wall of the upper water collecting tank 111.

[0032] Specifically, the material of the two reinforcing plates 6 in the present invention is Q355B steel, and the size is 150×120×10 mm.

[0033] By providing two reinforcing plates 6, the stress bearing capacity of the connection between the second through hole and the other end of the water inlet pipe 4 and the stress bearing capacity of the connection between the first through hole and the water outlet pipe 5 can be enhanced, thereby preventing the outer periphery of the first through hole and the second through hole of the upper water collecting tank 111 from being deformed when water is frequently inflowed or drained.

[0034] Optionally, the blocking plate 3 is located near the unsealed portion of the partition 2 .

[0035] In a specific embodiment, when the plugging plate 3 is located at a position far away from the unsealed portion of the partition 2, and one end of the water inlet pipe 4 extends into the lower water collecting tank 112 and is located on one side of the plugging plate 3, it is easy for the water flow between the unsealed portion of the partition 2 and the other side of the plugging plate 3 to be unable to be discharged into the upper water collecting tank 111 through circulation, which may still cause uneven circulation of the bottom water flow and poor cooling effect on the bottom plate 12. When the plugging plate 3 is located near the unsealed portion of the partition 2, the above situation can be avoided, and the cooling effect on the bottom plate 12 is improved.

[0036] Furthermore, when the blocking plate 3 is located at the unsealed portion of the partition 2, when the other side of the blocking plate 3 is impacted by the water flow inside the lower water collecting tank 112, the stress at the connection between the blocking plate 3 and the partition 2 is relatively concentrated, which can easily cause the connection to loosen. However, when the blocking plate 3 is located close to the unsealed portion of the partition 2, the stress at the connection between the blocking plate 3 and the partition 2 is relatively dispersed, and the connection is more stable. When the other side of the blocking plate 3 is impacted by the water flow inside the lower water collecting tank 112, the connection is not easy to loosen.

[0037] Optionally, one end of the water inlet pipe 4 is an L-shaped pipe, and the end of the transverse portion of the L-shaped pipe faces a side away from the blocking plate 3 .

[0038] Compared with the prior art in which one end of the water inlet pipe 4 is a straight pipe, one end of the water inlet pipe 4 of the utility model is an L-shaped pipe, which can avoid the impact force of the water flow on the bottom plate 12 during water injection, thereby protecting the bottom plate 12 from damage and extending the service life of the bottom plate 12.

[0039] like Figure 1 As shown, the other end of the water inlet pipe 4 of the prior art is an inclined end. In this case, the stress at the top of the connection between the other end of the water inlet pipe 4 and the top of the outer wall of the water collecting tank 11 is relatively concentrated, and the connection is more likely to deform. Figure 2 As shown, the other end of the water inlet pipe 4 in the utility model is set as a horizontal end, which can not only evenly disperse the stress at the connection, but also make it easier to match and connect the reinforcing plate 6 and the other end of the water inlet pipe 4, thereby completing the enhancement of the peripheral stress bearing capacity of the first through hole of the upper water collecting tank 111.

[0040] Optionally, a water jacket of a mixing iron furnace further includes a plurality of lifting ears 7 , which are evenly distributed on the top of the outer wall of the upper water collecting tank 111 and are all fixedly connected to the top of the outer wall of the upper water collecting tank 111 .

[0041] Specifically, the number of the lifting lugs 7 in the present invention is three. The water jacket body 1 can be stably suspended on external equipment by using a plurality of lifting lugs 7 evenly distributed on the top of the outer wall of the upper water collecting tank 111.

[0042] Furthermore, the fixed connections adopted in the present invention are all welding.

[0043] In summary, by setting a partition 2 in the water collecting tank 11, the water collecting tank 11 is divided into an upper water collecting tank 111 and a lower water collecting tank 112, and the upper water collecting tank 111 is connected to the lower water collecting tank 112 through the unsealed part on the partition 2. When water is continuously injected into the lower water collecting tank 112, the water that has absorbed heat in the lower water collecting tank 112 can be discharged to the upper water collecting tank 111 through the continuously injected water flow, thereby completing the water circulation inside the lower water collecting tank 112, improving the cooling effect on the bottom plate 12, reducing the number of times the bottom plate 12 is replaced, reducing the impact on the production operations of the production workshop, and reducing the safety hazards caused by water leakage of the bottom plate 12. The water flowing into the lower water collecting tank 112 is baked by the high-temperature molten iron in the molten iron receiving body 13, and scale is easily generated. A part of the scale and impurities in the lower water collecting tank 112 can move in the lower water collecting tank 112 through the gap between the blocking plate 3 and the bottom plate 12, and the other part of the scale and impurities can be discharged from the lower water collecting tank 112 through the water circulation inside the lower water collecting tank 112, thereby preventing the scale or impurities in the lower water collecting tank 112 from stagnation and accumulation, and then adhering to the inner wall of the lower water collecting tank 112, thereby improving the cooling effect on the bottom plate 12.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
