The cooling pipe 24 is tightly attached to the side of the mineral arc furnace 1, so that the cold water inside the cooling pipe 24 takes away the heat in the mineral arc furnace 1. When the cooling pipe 24 affects the normal working process or the damaged cooling pipe 24 needs to be replaced, the cooling pipe 24 is rotated to disengage the screw at the bottom of the cooling pipe 24 from the fixed screw 212, and the cooling pipe 24 is slid upward to make the insert pipe 23 slide into the rubber leak-proof pad 22, so as to facilitate the removal of the cooling pipe 24.

[0027] Example 2

[0028] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the water circulation mechanism 3 includes a water delivery port 31, the water delivery port 31 is fixedly connected to the input end of the water inlet 213, the top surface of the water delivery port 31 is fixedly connected to a water delivery pipe 32, the side of the water delivery pipe 32 is fixedly connected to a water valve 33, the number of the water delivery pipes 32 is two, the two water delivery pipes 32 are respectively fixedly connected to the left and right ends of the water valve 33, the bottom surface of the water valve 33 is fixedly connected to a main pipeline 34, one end of the main pipeline 34 is fixedly connected to a water delivery pump 35, and the side of the water delivery pump 35 is fixedly connected to a water storage device 36.

[0029] In this embodiment, the cooled water inside the water tank 361 is pumped into the main pipeline 34 by the water pump 35. The water can be controlled by the water valve 33.

The water port 31 can fix the water pipe 32 at the input end of the water inlet 213.

[0030] Example 3

[0031] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the water storage device 36 includes a water tank 361, the water outlet of the water tank 361 is fixedly connected to the side of the water pump 35, the outer surface of the water tank 361 is fixedly connected to a protection frame 362, the top surface of the water tank 361 is provided with a water circulation inlet 363, the water pump 35 is fixedly connected to the output end of the water circulation inlet 363, one end of the top surface of the water tank 361 is fixedly connected to a water injection port 364, the side of the water tank 361 is fixedly connected to a drain valve 369, the side of the protection frame 362 is fixedly connected to a side frame 365, the inside of the side frame 365 is fixedly connected to a motor 366, the output shaft of the motor 366 is fixedly connected to a fan blade 367, and one end of the inside of the side frame 365 is fixedly connected to a protective net 368.

[0032] In this embodiment, water can be stored in the water tank 361, and the protection frame 362 protects the water tank 361 to increase the service life of the device. When cooled hot water flows in from the water circulation inlet 363, the motor 366 drives the fan blades 367 to blow air to take away the heat in the water tank 361, so that the water in the water tank 361 cools down, which is convenient for cooling again. The water inlet 364 and the drain valve 369 facilitate replacement or addition of water in the water tank 361.

[0033] The following is a detailed description of the working principle of the circulating water cooling system of the submerged arc furnace.

When the cooling tube 24 needs to be replaced or a gap is needed for operation, it is only necessary to rotate the cooling tube 24 so that the screw thread on the bottom of the cooling tube 24 is disengaged from the fixed screw thread 212, and then pull the cooling tube 24 upward. Due to the material characteristics of the rubber leak-proof pad 22, the insert tube 23 can shake inside the rubber leak-proof pad 22, making it convenient to remove the cooling tube 24 for replacement. When the water flows from the inside of the cooling tube 24 into the inside of the water outlet pipe 29, the heated water flows from the inside of the drain pipe 211 into the inside of the water tank 361 through the pumping of the water outlet pump 210, thereby realizing water circulation.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
