Secondly, the uneven temperature distribution inside the furnace will reduce the smelting efficiency, affect the product quality and increase the production cost. Moreover, the increase of the thermal stress of the high-temperature furnace body may cause safety accidents such as furnace body rupture and melt leakage, posing a direct threat to the safety of personnel.

[0027] Embodiment

[0028] Please refer to Figures 1-6 , the present utility model provides a technical solution: a high-efficiency cooling device for a submerged arc furnace, including a cooling component 10, and the cooling component 10 includes a cooling sleeve 11, a heat conduction cylinder 12, a flow guide plate 13, a base 14 and a support leg 15;

[0029] The inner side wall of the cooling sleeve 11 is fixedly connected with a heat conduction cylinder 12. The cooling sleeve 11 is a hollow structure inside. A flow guide plate 13 is fixedly connected between the cooling sleeve 11 and the heat conduction cylinder 12. The bottom of the cooling sleeve 11 is fixedly connected with a base 14. The bottom of the base 14 is symmetrically and fixedly connected with support legs 15. The coolant spirally rises under the action of the flow guide plate 13 inside the cooling sleeve 11 and fully absorbs the heat of the furnace body during the rising process;

[0030] A heat dissipation component 20 is arranged on one side of the cooling component 10, and a water tank component 30 is arranged on one side of the heat dissipation component 20.

[0031] In this embodiment, specifically: The heat dissipation component 20 includes a gantry 21, a heat dissipation box 22, and fins 23. The inner side wall of the gantry 21 is fixedly connected to the heat dissipation box 22. The two sides of the heat dissipation box 22 are evenly fixedly connected with fins 23. The fins 23 are used to increase the heat dissipation area. By the operation of the drainage fan 24, external air enters from the bottom of the baffle 26 and takes away part of the heat when passing through the surface of the fins 23.

[0032] In this embodiment, specifically: Drainage fans 24 are symmetrically installed at the top of the gantry 21.

[0033] In this embodiment, specifically: The top end of the heat dissipation box 22 is communicated with a first liquid return pipe 25. One end of the first liquid return pipe 25 is communicated with the cooling sleeve 11. After the coolant fully absorbs the heat of the furnace body, it enters the interior of the heat dissipation box 22 through the first liquid return pipe 25.

[0034] In this embodiment, specifically: Two baffles 26 are symmetrically and fixedly connected to both sides of the gantry 21. The baffles 26 are used to control the air inlet direction so that the air flow direction is the same as the direction of the fins 23, thereby reducing the resistance.

[0035] In this embodiment, specifically: The water tank assembly 30 includes a box body 31 and a controller 32. The controller 32 is installed on the top of the box body 31. The cooling device is controlled to work and automatically adjusted through the controller 32.

[0036] In this embodiment, specifically: A liquid inlet pipe 33 is communicated with one side of the box body 31. One end of the liquid inlet pipe 33 is communicated with the cooling sleeve 11. A water pump 34 is installed on the liquid inlet pipe 33. When the submerged arc furnace is working, the water pump 34 works synchronously to send the coolant in the box body 31 into the interior of the cooling sleeve 11 through the liquid inlet pipe 33.

[0037] In this embodiment, specifically: A second liquid return pipe 35 is communicated with the top of the box body 31. A temperature sensor 36 is installed on the second liquid return pipe 35. The signal output end of the temperature sensor 36 is signal-connected to the signal input end of the controller 32. The temperature of the cooled coolant is detected through the temperature sensor 36. If the coolant temperature is higher than the set range, the power of the water pump 34 is increased to increase the coolant flow rate, and at the same time, the power of the drainage fan 24 is increased to increase the heat dissipation speed. On the contrary, if the coolant temperature is lower than the set range, the power of the water pump 34 and the drainage fan 24 is reduced, saving energy while ensuring the cooling effect.

[0038] Working principle or structural principle: During use, the heat conduction cylinder 12 is installed closely against the furnace body of the submerged arc furnace. When the submerged arc furnace is working, the water pump 34 works synchronously to send the coolant in the box body 31 into the inside of the cooling sleeve 11 through the liquid inlet pipe 33. Under the action of the guide plate 13 inside the cooling sleeve 11, the coolant spirally rises, and fully absorbs the heat of the furnace body during the rising process. Subsequently, it enters the inside of the heat dissipation box 22 through the first liquid return pipe 25. The heat dissipation area is increased by using the fins 23. Through the operation of the drainage fan 24, external air enters from the bottom of the baffle 26 and takes away part of the heat when passing through the surface of the fins 23, so as to quickly reduce the temperature of the coolant. The cooled coolant enters the box body 31 through the second liquid return pipe 35 and participates in the circulating cooling work. The temperature of the cooled coolant is detected by the temperature sensor 36. If the coolant temperature is higher than the set range, the power of the water pump 34 is increased to increase the flow rate of the coolant, and at the same time, the power of the drainage fan 24 is increased to increase the heat dissipation speed. On the contrary, if the coolant temperature is lower than the set range, the power of the water pump 34 and the drainage fan 24 is reduced, saving energy while ensuring the cooling effect.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
