Technical Field

[0001] This utility model relates to the field of furnace nozzle cooling water, and in particular to a protective device for the cooling water at the furnace nozzle of an calcium carbide furnace. Background Technology

[0002] Cooling water at the outlet of a calcium carbide furnace is a critical medium specifically designed to protect the furnace's discharge port. During calcium carbide production, the furnace temperature is extremely high, and the high temperature of the material at the outlet poses a serious threat to the nozzle material. To prevent damage to the nozzle due to high temperatures, cooling water circulates through pipes that surround or are built into the nozzle structure to absorb and remove a large amount of heat, thereby ensuring that the nozzle can operate stably in extreme working environments, extending its service life and ensuring the continuity of production.

[0003] During the calcium carbide production process, the hot molten iron flows out during tapping, with a temperature of about 2200℃. Traditional cooling water pipes are easily damaged, causing cooling water to leak into the calcium carbide pot, which can lead to serious safety accidents such as explosions. Although there are some protective measures in the existing technology, their effectiveness is limited and they cannot fundamentally solve the problems of cooling water pipe damage and water leakage.

[0004] Therefore, in response to the problem that during the calcium carbide production process, the hot molten iron flows out during tapping (the temperature of which is about 2200°C), and the traditional cooling water pipes are easily damaged, leading to leakage of cooling water into the calcium carbide pot and causing serious safety accidents, a protective device for the cooling water at the tapping nozzle of the calcium carbide furnace can be designed. This device consists of a protective box and a high-temperature and high-strength casting layer on the outside of the cooling pipe. Utility Model Content

[0005] In order to overcome the problem that during the calcium carbide production process, the hot molten iron flowing out during tapping (the temperature of which is about 2200℃) can easily damage traditional cooling water pipes, causing cooling water to leak into the calcium carbide pot and thus leading to serious safety accidents.

[0006] The technical solution of this utility model is as follows: a protective device for cooling water at the outlet of an calcium carbide furnace, including a cooling pipe, a casting frame, a protective box one, and a protective box two. The upper end of the cooling pipe is movably connected to the protective box two, and the bottom of the cooling pipe is movably connected to the protective box one. The protective box one and the protective box two are movably connected. A casting frame is provided on the outer side of the protective box one and the protective box two.

A bolt one is movably connected inside the fixing block one. A fixing block two is fixedly connected to the top right position of the protective box one, and the same fixing block two is fixedly connected to the top right position of the protective box one. A bolt two is movably connected inside the fixing block two.

[0007] Preferably, the cooling pipe is encased by protective boxes one and two. Bolt one is installed on fixing block one, and bolt two is installed on fixing block two, thus fixing protective boxes one and two together. Then, a casting frame is spliced ​​onto the outside of protective boxes one and two. The casting frame is composed of multiple splicable plates. High-temperature resistant and high-strength castable is used to cast the inside of the casting frame, forming a casting layer that protects protective boxes one and two. The casting frame is then disassembled. During use, cooling water flows through inlet pipe one and outlet pipe one within the protective box to cool the cooling pipe.

[0008] Preferably, a second water inlet pipe is fixedly connected to the front of the top of the cooling pipe, and a second water outlet pipe is fixedly connected to the rear of the top of the cooling pipe. The other end of the second water inlet pipe passes through the casting frame and is fixedly connected to a water tank.

[0009] Preferably, the other end of the water inlet pipe passes through the casting frame and is fixedly connected to the water tank, and the water pump is fixedly connected inside the water tank at the position corresponding to the water inlet pipe.

[0010] Preferably, the bottom of the water pump three is fixedly connected to the water inlet pipe two, and the water pump two is fixedly connected to the inside of the water tank at the position corresponding to the water inlet pipe two.

[0011] Preferably, the bottom of the second water pump is fixedly connected to the first water pump, and the right end of the first water outlet pipe passes through the casting frame and is fixedly connected to the first water pump.

[0012] Preferably, a heat dissipation pipe is fixedly connected to the right end of the water pump, and the other end of the heat dissipation pipe is fixedly connected to the water tank.

[0013] Preferably, a fixing plate is fixedly connected to the rear end of the water tank, and four fans are fixedly connected to the rear end of the fixing plate.

[0014] The beneficial effects of this utility model are:

[0015] The cooling pipes are encased in protective boxes one and two. Bolt one is installed on fixing block one, and bolt two is installed on fixing block two, thus securing protective boxes one and two together. A casting frame is then attached to the outside of protective boxes one and two. The casting frame is composed of multiple interlocking plates. High-temperature resistant, high-strength castable refractory is used to cast the interior of the casting frame, forming a protective layer for protective boxes one and two. The casting frame is then disassembled. During use, cooling water flows through inlet pipe one and outlet pipe one within the protective box to cool the cooling pipes. This prevents damage to the cooling water pipes caused by the outflow of high-temperature molten iron during the tapping process, which could lead to leakage of cooling water into the calcium carbide pot and cause serious safety accidents.

The interior of the fixing block 6 is movably connected to a bolt 7. The top right side of the protective box 2 is fixedly connected to a fixing block 8, and the interior of the fixing block 8 is movably connected to a bolt 9. A water inlet pipe 11 is fixedly connected to the front right side of the protective box 2, and a water outlet pipe 10 is fixedly connected to the bottom rear side of the protective box 2. The cooling pipe 4 is wrapped by the protective box 2 and the protective box 3. The protective box 2 and the protective box 3 are fixedly connected by installing bolt 7 on the fixing block 6 and bolt 9 on the fixing block 8. Then, the casting frame 1 is spliced ​​on the outside of the protective box 2 and the protective box 3. The casting frame 1 is spliced ​​from multiple splicable plates. High temperature and high strength castable is used to cast the inside of the casting frame 1 to form a casting layer to protect the protective box 2 and the protective box 3. Then the casting frame 1 is disassembled. When in use, cooling water flows through the water inlet pipe 11 and the water outlet pipe 10 in the protective box to cool the cooling pipe 4.

[0023] Please see Figures 1-4 In this embodiment, a second water inlet pipe 12 is fixedly connected to the front of the top of the cooling pipe 4, and a second water outlet pipe 13 is fixedly connected to the rear of the top of the cooling pipe 4. The other end of the second water inlet pipe 12 passes through the casting frame 1 and is fixedly connected to a water tank 14. Cooling water in the water tank 14 enters the cooling pipe 4 through the second water inlet pipe 12 and flows out through the second water outlet pipe 13. The other end of the first water inlet pipe 11 passes through the casting frame 1 and is fixedly connected to the water tank 14. A third water pump 21 is fixedly connected inside the water tank 14 at the position corresponding to the first water inlet pipe 11. A second water pump 22 is fixedly connected to the bottom of the third water pump 21. A second water pump 19 is fixedly connected inside the water tank 14 at the position corresponding to the second water inlet pipe 12. The third water pump 21 and the second water pump 22 pump the cooling water in the water tank 14 into the first water inlet pipe 11.

[0024] Please see Figures 3-4In this embodiment, the bottom of the second water pump 19 is fixedly connected to the first water pump 20, and the right end of the first water outlet pipe 10 passes through the casting frame 1 and is fixedly connected to the first water pump 15. The second water pump 19 and the first water pump 20 draw the cooling water in the water tank 14 into the second water inlet pipe 12. The right end of the first water pump 15 is fixedly connected to the heat dissipation pipe 16, and the other end of the heat dissipation pipe 16 is fixedly connected to the water tank 14. The third water pump 21 draws the water in the cooling pipe 4 into the heat dissipation pipe 16 for heat dissipation and cooling. The rear end of the water tank 14 is fixedly connected to the fixing plate 17, and the rear end of the fixing plate 17 is fixedly connected to four fans 18. The four fans 18 blow air onto the heat dissipation pipe 16 to accelerate heat dissipation.

[0025] During operation, protective boxes 1 (2) and 2 (3) are used to enclose the cooling pipe 4. Bolt 1 (7) is installed on fixing block 1 (6), and bolt 2 (9) is installed on fixing block 2 (8), thus fixing protective boxes 1 (2) and 2 (3) together. Then, the casting frame 1 is assembled onto the outside of protective boxes 1 (2) and 2 (3). The casting frame 1 is composed of multiple interlocking plates. High-temperature resistant, high-strength castable refractory is used to cast the interior of the casting frame 1, forming a protective layer for protective boxes 1 (2) and 2 (3). The casting frame 1 is then disassembled. During use, cooling water is introduced through the inlet... Water pipe 11 and water outlet pipe 10 flow inside the protective box to cool the cooling pipe 4. Cooling water in water tank 14 enters the cooling pipe 4 through water inlet pipe 2 12 and flows out through water outlet pipe 2 13. Water pump 2 19 and water pumping pipe 1 20 draw the cooling water in water tank 14 into water inlet pipe 2 12. Water pump 3 21 and water pumping pipe 2 22 draw the cooling water in water tank 14 into water inlet pipe 11. Water pump 3 21 draws the water in cooling pipe 4 into heat dissipation pipe 16 for cooling. Four fans 18 blow air onto heat dissipation pipe 16 to accelerate cooling. The cooled water enters water tank 14.

[0026] Through the above steps, the cooling pipe 4 is wrapped with protective box 1 (2) and protective box 2 (3). By installing bolt 1 (7) on fixing block 1 (6) and bolt 2 (9) on fixing block 2 (8), protective box 1 (2) and protective box 2 (3) are fixedly connected together. Then, casting frame 1 is spliced ​​on the outside of protective box 1 (2) and protective box 2 (3). Casting frame 1 is made of multiple splicable plates. High-temperature resistant and high-strength castable is used to cast the inside of casting frame 1 to form a casting layer that protects protective box 1 (2) and protective box 2 (3). Then, casting frame 1 is disassembled. When in use, cooling water flows through inlet pipe 11 and outlet pipe 10 in the protective box to cool the cooling pipe 4. This solves the problem that in the calcium carbide production process, due to the outflow of high-temperature molten iron during tapping (the temperature of the molten iron is about 2200℃), traditional cooling water pipes are easily damaged, causing cooling water to leak into the calcium carbide pot, which can lead to serious safety accidents.
