Description

Technical Field

[0001] The utility model relates to the technical field of cooling and protecting electrodes of submerged arc furnaces, in particular to an internal cooling structure of a copper tile. Background Art

[0002] Submerged arc furnace is an industrial equipment that uses electric energy to reduce metal elements in ore to liquid state. It is widely used in steel, nonferrous metal and other industries. The electrode system of submerged arc furnace is one of the core components of submerged arc furnace, and its performance directly affects the production efficiency and energy consumption of submerged arc furnace. Copper cooling components, referred to as copper tiles, are an important part of the electrode system of submerged arc furnace. Its main function is to cool the electrode to ensure the normal operation of the electrode in a high temperature environment.

[0003] Chinese patent announcement No. CN204555706U discloses a cooling protection device for electrodes of an electric arc furnace. The wave-shaped circulating water channel is evenly distributed in the protective sleeve body, so that the structural setting of the protection device is more reasonable and simple, and the occurrence of burning deformation and water leakage is reduced. The spacing of the circulating water channel gradually decreases with the direction of the water flow, which increases the flow speed of the circulating water. The wave-shaped protrusion increases the contact area of ​​the water, accelerates the heat dissipation speed, and improves the cooling effect. The arc-shaped pipe in the circuitous part of the circulating water channel makes the flow of the circulating water smoother without stagnation, effectively improving the cooling effect, and improving the overall working efficiency of the electric arc furnace, reducing unnecessary losses of the enterprise.

[0004] However, compared with the existing technology and comparative documents, the existing copper tile internal cooling structure adopts a spiral structure to accelerate the water flow rate during use in order to ensure the water flow rate and cooling effect. Long-term use can easily lead to a large amount of scale forming on the inner wall of the water tank. The scale is not easy to clean, and the scale will reduce the diameter of the water tank, which not only easily reduces the water flow rate, but also easily affects the thermal conductivity of the copper tile, resulting in reduced cooling effect.

The cooling water takes away the heat generated at the electrode during the flow in the water groove 2, thereby cooling the electrode. The water grooves 2 on the inner shell 102 and the outer shell 101 are both spiral structures, and sealing gaskets are installed on the opposite ends of the inner shell 102 and the outer shell 101. 3. The sealing gasket 3 seals the connection between the outer shell 101 and the inner shell 102, and the sealing gasket 3 is located outside the water tank 2. The inner diameter of the bottom end of the outer shell 101 is equal to the inner diameter of the inner shell 102. The bottom ends of the inner shell 102 and the outer shell 101 are both installed with fixing bolts 4. The outer shell 101 and the inner shell 102 are connected to form a copper tile body 1 through the fixing bolts 4 and the sealing ring 5. The bottom ends of the inner shell 102 and the outer shell 101 are both provided with threaded grooves for connecting the fixing bolts 4. The outer shell 101 and the outer shell 101 are both installed with sealing rings 5 ​​on the outside of the top ends.

[0024] like Figure 1 As shown, a water inlet pipe 6 is installed on the upper side of the outer shell 101, and cooling water enters the copper tile body 1 through the water inlet pipe 6. The water after absorbing heat is discharged through the water outlet pipe 7. The water outlet pipe 7 is installed on the lower side of the outer shell 101.

[0025] like Figure 1-Figure 2 As shown, the water inlet pipe 6 and the water outlet pipe 7 are both connected to the spliced ​​water tank 2, so that the cooling water can enter the water tank 2 through the water inlet pipe 6 and then be discharged from the water outlet pipe 7.

[0026] like Figure 1-Figure 2 As shown, a temperature measuring assembly 8 is installed on the outside of the water inlet pipe 6 and the water outlet pipe 7. The temperature measuring assembly 8 includes a water tank 801 and a temperature sensor 802. The temperature measuring assembly 8 can detect the inlet water temperature and the outlet water temperature.

[0027] like Figure 1 and Figure 3 As shown, the water inlet pipe 6 is connected to the pipe clamp of the water tank 801, so that the cooling water in the water tank 801 can enter the copper tile body 1 through the water inlet pipe 6, and the water outlet pipe 7 is connected to the pipe clamp of the water tank 801, and the discharged cooling water enters the water tank 801 through the water outlet pipe 7.

[0028] like Figure 1 and Figure 3 As shown, the temperature sensor 802 is fixedly connected to the water tank 801 , and the bottom end of the temperature sensor 802 is located in the water tank 801 , so that the water temperature can be detected by the temperature sensor 802 after the cooling water enters the water tank 801 .

[0029] like Figure 1 and Figure 3 As shown, a water inlet 9 is installed on the outside of the water tank 801 located at the water inlet pipe 6, and the water inlet 9 is connected to the pipe clamp of the water tank 801, so that it is convenient to connect an external water supply device through the water inlet 9, and then the cooling water enters the water tank 801 through the water inlet 9.

[0030] like Figure 1 and Figure 3 As shown, a water outlet 10 is installed outside the water tank 801 located at the water outlet pipe 7, and the water outlet 10 is connected to the pipe clamp of the water tank 801. After the temperature is measured, the used cooling water flows to the outside through the water outlet 10 for recovery.

[0031] Working principle of the device: When the device is used, the staff installs the inner shell 102 on the outside of the electrode, and then uses the fixing bolts 4 and the sealing ring 5 to connect the outer shell 101 and the inner shell 102 to form the copper tile body 1. At this time, the semicircular water tanks 2 on both sides are spliced ​​to form a circular spiral water tank 2, and the connection between the inner shell 102 and the outer shell 101 is sealed by the sealing gasket 3. Then the water inlet 9 is connected to the external water supply equipment, and the cooling water first enters the water tank 801 in the temperature measuring component 8 through the water inlet 9, and the inlet water temperature is measured by the temperature sensor 802. After detection, the detected water enters the copper tile body 1 through the water inlet pipe 6 and flows in the water tank 2. During the flow, the heat generated at the electrode is taken away to cool the electrode. The used high-temperature cooling water is discharged through the water outlet pipe 7 and enters the water tank 801 for outlet water temperature detection, and finally discharged through the water outlet 10 for recycling. After long-term use, the outer shell 101 and the inner shell 102 are separated. At this time, the side of the water tank 2 is completely exposed, which is convenient for the staff to clean its side wall, avoid scale reducing the diameter of the water tank 2, ensure water flow, and prevent affecting the thermal conductivity of the copper tile, thereby improving the cooling effect.
