Description

Technical Field

[0001] This utility model relates to the field of carbon-oxygen lance technology, and in particular to a carbon-oxygen lance circulating water cooling device. Background Technology

[0002] The carbon-oxygen lance is a key piece of equipment used to intensify the smelting process in electric arc furnace steelmaking. It mainly improves smelting efficiency by blowing oxygen into the molten pool. This system forms a complementary solution with Constar electric arc furnace smelting technology and plays an important role in optimizing the production process. The traditional oxygen blowing process uses manual operation to insert steel pipes into the molten pool, which has drawbacks such as high labor intensity, high safety risks, and unstable efficiency. The carbon-oxygen lance system improves the oxygen blowing process through mechanized operation and has become an indispensable part of the modern electric arc furnace steelmaking process.

[0003] However, during the use of existing carbon oxygen lances, the lance barrel is prone to overheating in the high-temperature smelting environment, which can lead to deformation, burns, or even explosion. After the explosion, it is easy to react with oxygen, creating unnecessary danger. Utility Model Content

[0004] In view of the problems that existing carbon oxy-liquid lances are prone to overheating, deformation, burning or even bursting in high-temperature smelting environments, and that the bursting lance is prone to reacting with oxygen and causing unnecessary danger, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a carbon-oxygen gun circulating water cooling device, including a base, a carbon-oxygen gun at the upper end of the base, a cooling component sleeved on the outer wall of the carbon-oxygen gun tube, the cooling component including two sets of symmetrical collars sleeved on the outer walls of both ends of the carbon-oxygen gun tube, multiple sets of water cooling pipes connected between the collars, a first heat dissipation copper pipe sleeved on the outer wall of the collars, a second heat dissipation copper pipe sleeved on the outer wall of the first heat dissipation copper pipe, a heat dissipation pipe inserted in the inner cavity of the second heat dissipation copper pipe, a water tank at the upper end of the base, a water pump at the bottom end of the water tank, a connecting pipe at the outlet end of the water pump, an air pipe at the upper end of the water tank, an air pump connected to the air outlet end of the air pipe, a liquid outlet pipe connected to one end of the heat dissipation pipe, multiple sets of heat dissipation holes opened on the outer wall of the second heat dissipation copper pipe, and heat dissipation fins fixed on one side of the multiple sets of heat dissipation holes opened on the outer wall of the second heat dissipation copper pipe.

[0006] In a preferred embodiment of the carbon-oxygen gun circulating water cooling device of this utility model, the outer wall of the water cooling pipe is respectively attached to the outer wall of the carbon-oxygen gun barrel and the inner wall of the first heat dissipation copper pipe.

[0007] As a preferred embodiment of the carbon-oxygen gun circulating water cooling device of this utility model, the heat dissipation tube is configured as a spiral, the end of the heat dissipation tube away from the liquid outlet tube is connected to one of the sets of collars, and the end of the liquid outlet tube away from the heat dissipation tube is connected to the upper end of the water tank.

[0008] As a preferred embodiment of the carbon-oxygen gun circulating water cooling device of this utility model, the heat dissipation fins are configured as V-shaped, and the heat dissipation holes are located at the middle of the heat dissipation fins.

[0009] In a preferred embodiment of the carbon-oxygen gun circulating water cooling device of this utility model, the end of the air pump away from the air pipe is connected to the inside of the second heat dissipation copper pipe.

[0010] As a preferred embodiment of the carbon-oxygen gun circulating water cooling device of this utility model, the outer wall of the carbon-oxygen gun and the upper end of the base are hinged together, and the upper end of the base is hinged to the lower end of the carbon-oxygen gun with a cylinder, and the extension end of the cylinder is hinged to the lower end of the outer wall of the carbon-oxygen gun.

[0011] As a preferred embodiment of the carbon-oxygen gun circulating water cooling device of this utility model, the water tank is provided with a liquid inlet at the upper end.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects: 1. In this utility model, when the water pump is started, the water pump injects the coolant in the water tank into the collar at the front end of the gun barrel through the connecting pipe. The collar distributes the coolant to multiple sets of water-cooling pipes. The outer wall of the water-cooling pipes is in contact with the outer wall of the gun barrel. As the coolant flows along the water-cooling pipes, it carries away the heat of the gun barrel, preventing the gun barrel from deforming or bursting due to high temperature.

[0013] 2. In this invention, after the coolant temperature rises, the heated coolant flows into the heat dissipation pipe. The air pipe injects air into the inner cavity of the second heat dissipation copper pipe through an air pump. The air dissipates the heat from the second heat dissipation copper pipe, the heat dissipation pipe, and the coolant in the heat dissipation pipe through the heat dissipation holes. The air discharged from the heat dissipation holes blows air onto the heat dissipation fins, thereby accelerating the heat dissipation of the heat dissipation fins. After the heated coolant is cooled inside the second heat dissipation copper pipe, it flows back to the water tank through the liquid outlet pipe. The coolant forms a circulation loop, allowing the coolant to be reused repeatedly and reducing coolant consumption. Attached Figure Description

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0017] Reference Figures 1-4 This is the first embodiment of the present invention, providing a carbon-oxygen gun circulating water cooling device, including a base 1, a carbon-oxygen gun 2 mounted on the upper end of the base 1, a cooling component 3 fitted onto the outer wall of the gun barrel of the carbon-oxygen gun 2, the cooling component 3 including two sets of symmetrical collars 301 fitted onto the outer walls of both ends of the gun barrel of the carbon-oxygen gun 2, multiple sets of water cooling pipes 302 connected between the collars 301, a first heat dissipation copper pipe 303 fitted onto the outer wall of the collars 301, and a second heat dissipation copper pipe 304 fitted onto the outer wall of the first heat dissipation copper pipe 303. A heat dissipation tube 305 is inserted into the inner cavity of the copper tube 304. A water tank 4 is provided at the upper end of the base 1. A water pump 306 is provided at the bottom end of the water tank 4. A connecting pipe 307 is provided at the outlet end of the water pump 306. An air pipe 309 is provided at the upper end of the water tank 4. An air pump 310 is connected to the air outlet end of the air pipe 309. A liquid outlet pipe 308 is connected to one end of the heat dissipation tube 305. Multiple sets of heat dissipation holes 311 are opened on the outer wall of the second heat dissipation copper tube 304. A heat dissipation fin 312 is fixed on one side of the multiple sets of heat dissipation holes 311 opened on the outer wall of the second heat dissipation copper tube 304.

[0018] The outer wall of the water-cooling pipe 302 is in contact with the outer wall of the barrel of the carbon-oxygen gun 2 and the inner wall of the first heat dissipation copper pipe 303.

[0019] The heat dissipation pipe 305 is spiral-shaped. The end of the heat dissipation pipe 305 away from the liquid outlet pipe 308 is connected to one of the sets of collars 301. The end of the liquid outlet pipe 308 away from the heat dissipation pipe 305 is connected to the upper end of the water tank 4.

[0020] The heat dissipation fins 312 are V-shaped, and the heat dissipation holes 311 are located in the middle of the heat dissipation fins 312.

[0021] The end of the air pump 310 away from the air pipe 309 is connected to the inside of the second heat dissipation copper pipe 304.

[0022] The outer wall of the carbon-oxygen gun 2 is hinged to the upper end of the base 1. The upper end of the base 1 is hinged to the lower end of the carbon-oxygen gun 2 and a cylinder 5 is provided. The extension end of the cylinder 5 is hinged to the lower outer wall of the carbon-oxygen gun 2.

[0023] The water tank 4 has a liquid inlet at the top.

[0024] Coolant is filled into water tank 4 through the inlet at the top. When the barrel temperature rises during the operation of carbon-oxygen gun 2, water pump 306 and gas pipe 309 are started. Water pump 306 injects the coolant in water tank 4 into the collar 301 at the front end of the barrel through connecting pipe 307. The collar 301 distributes the coolant to multiple sets of water-cooling pipes 302. The outer wall of the water-cooling pipes 302 is in contact with the outer wall of the barrel. As the coolant flows along the water-cooling pipes 302, it carries away the heat from the barrel. At the same time, the temperature of the collar 301 and the water-cooling pipes 302 is reduced. As the temperature rises, the first heat dissipation copper pipe 303, the collar 301, and the water-cooling pipe 302 come into contact with each other. The collar 301 and the water-cooling pipe 302 transfer heat to the first heat dissipation copper pipe 303. The first heat dissipation copper pipe 303 and the second heat dissipation copper pipe 304 come into contact with each other, and the first heat dissipation copper pipe 303 transfers heat to the second heat dissipation copper pipe 304. The outer wall of the second heat dissipation copper pipe 304 is provided with multiple sets of heat dissipation fins 312. The second heat dissipation copper pipe 304 transfers heat to the heat dissipation fins 312. After the temperature of the coolant rises, the increased temperature of the coolant flows into the heat dissipation fins. In tube 305, because the heat dissipation tube 305 is spirally arranged inside the cavity of the second heat dissipation copper tube 304, the coolant with rising temperature can remain in the second heat dissipation copper tube 304 for a longer time. Air tube 309 injects air into the cavity of the second heat dissipation copper tube 304 through air pump 310. Outside air flows along the cavity of the second heat dissipation copper tube 304, cooling the coolant in the second heat dissipation copper tube 304 and heat dissipation tube 305. The air dissipates the heat from the second heat dissipation copper tube 304, heat dissipation tube 305, and the coolant in heat dissipation tube 305. The air is discharged through the heat dissipation hole 311, which blows air onto the heat dissipation fins 312, accelerating the heat dissipation of the heat dissipation fins 312. The coolant, whose temperature rises, is cooled inside the second heat dissipation copper pipe 304 and then flows back to the water tank 4 through the outlet pipe 308. This cycle repeats, which allows the temperature of the carbon-oxygen gun 2 barrel to drop quickly, preventing the barrel from deforming or bursting due to high temperature. At the same time, the coolant forms a circulation loop, allowing the coolant to be reused and reducing coolant consumption.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
