Technical Field
[0001] This utility model relates to the field of water-cooled furnace shell maintenance technology, specifically, to a water-cooled furnace shell for electric furnaces that is easy to maintain. Background Technology
[0002] The water-cooled furnace shell is an important component of the electric furnace. It uses water cooling technology to reduce the temperature of the furnace shell and improve the stability and service life of the electric furnace. However, when the water cooling tubes are damaged during long-term use, how to quickly disassemble, repair, and replace them is an urgent problem to be solved.
[0003] A search revealed that CN220380280U discloses a water-cooled furnace shell for an electric furnace, belonging to the field of metallurgical electric furnace equipment. It includes a dry furnace shell, a plate-type water-cooled furnace shell, and a spray-type water-cooled furnace shell. The spray-type water-cooled furnace shell is installed on the side wall of the furnace's containment pool, the plate-type water-cooled furnace shell is installed on the side wall of the portion above the containment pool, and the dry furnace shell is installed on the side wall of the portion below the containment pool. The plate-type water-cooled furnace shell is circulated with closed-loop pressurized water, while the spray-type water-cooled furnace shell uses exposed nozzles to spray cooling water. Both types work together to cool the furnace shell, avoiding the risk of water leakage during cooling, ensuring cooling effectiveness, and facilitating inspection and maintenance.
[0004] The aforementioned water-cooled furnace shell of an electric furnace is designed by having a water inlet pipe on the outside of the furnace shell. Cooling water is introduced through the water inlet pipe and sprayed onto the outside of the furnace shell from the nozzles to cool it down. The water cooling cycle is completed in conjunction with a return water device. However, the drawback of this design is that the water inlet pipe and the nozzles are fixed on the outside of the furnace shell. Therefore, if the water inlet pipe and the nozzles are broken or damaged, it is not convenient to remove them separately from the outside of the furnace shell for corresponding repair and replacement.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0024] Please see Figure 3 and Figure 5This utility model provides a technical solution: an easy-to-maintain electric furnace water-cooled furnace shell, including an external assembly 1, which includes a water-cooled furnace body 11. The external assembly 1 also includes an upper hanging plate 12 and a lower hanging slot 13, which are respectively fixedly connected to the upper and lower sides of the water-cooled furnace body 11. The top of the upper hanging plate 12 is provided with an annular groove 121. A water-cooling component 3 is provided on the outside of the water-cooled furnace body 11 at the upper hanging plate 12. The water-cooling component 3 includes a spray plate 34 that can spray and cool the outer shell of the water-cooled furnace body 11. The water-cooling component 3 also includes an inner hanging frame 32 that can be disassembled and attached to the outside of the water-cooled furnace body 11. A circulation component 2 that can circulate the spray cooling water is also provided on the outside of the inner hanging frame 32. This design solves the problem in the prior art that the water inlet pipe and the nozzle are fixed on the outside of the furnace shell. Therefore, when the water inlet pipe and the nozzle are broken or damaged, it is not convenient to remove them from the outside of the furnace shell for repair and replacement.
[0025] Please see Figure 3 The water-cooling assembly 3 also includes an annular water tank 31, which is fixedly connected to the outside of the inner bracket 32. The inner bracket 32 matches the annular groove 121. The annular water tank 31 is inserted into the annular groove 121 through the inner bracket 32. The inner bracket 32 can be supported on the top of the upper bracket 12 before installation through the upper bracket 12 and the annular groove 121.
[0026] Please see Figure 3 The water-cooling component 3 also includes a mounting plate 321, which is fixedly connected to both sides of the inner bracket 32. Bolts 33 are inserted into the mounting plate 321, and nuts 331 are threaded to the ends of the bolts 33. By providing bolts 33 and nuts 331 at the mounting plate 321, the two sets of annular water tanks 31 can be fixedly installed around the water-cooled furnace body 11 on the upper part of the upper bracket 12.
[0027] Please see Figure 3 and Figure 5 The water-cooling assembly 3 also includes an inlet pipe 35 that is threadedly connected to the bottom of the annular water tank 31 at equal intervals. The water-cooling assembly 3 also includes a sealing ring 351, which is fixedly connected to the lower part of the thread on the outside of the inlet pipe 35. The water-cooling assembly 3 also includes a spray plate 34, which is fixedly connected to the bottom of the inlet pipe 35. The water-cooling assembly 3 also includes a spray head 341, which is fixedly connected to the side of the spray plate 34 at equal intervals. The isomorphic spray plate 34 and spray head 341 can spray the introduced cooling water onto the outer shell of the water-cooled furnace body 11 to complete the cooling work. At the same time, by turning the inlet pipe 35 at the bottom of the annular water tank 31, the independent disassembly and assembly of a single spray plate 34 can be completed.
[0028] Please see Figure 1The circulation assembly 2 also includes a bracket 21, which is fixedly connected to the outside of the annular water tank 31. The circulation assembly 2 also includes a cooling tank 22, which is fixedly installed on the top of the bracket 21. An inlet 221 is also fixedly connected to the top of the cooling tank 22. The circulation assembly 2 also includes a discharge pipe 23, one end of which is fixedly connected to the cooling tank 22, and the other end of which is fixedly connected to the annular water tank 31. The circulation assembly 2 also includes a first water pump 231, which is fixedly installed on the outside of the discharge pipe 23. The circulation assembly 2 also includes a return pipe 24, which is fixedly connected to the outside of the cooling tank 22. The end of the return pipe 24 furthest from the cooling tank 22 is located inside the lower hanging slot 13. The circulation component 2 also includes a second water pump 241, which is fixedly connected to the outside of the return pipe 24. The second water pump 241 injects cooling water into the cooling tank 22 through the water inlet 221. Starting the first water pump 231 allows the cooling water in the cooling tank 22 to enter the annular water chamber 31 through the discharge pipe 23, and then flow to the inlet pipe 35 and the spray plate 34 until it is sprayed from the spray head 341 to the outside of the water-cooled furnace body 11 to complete the cooling. The spray plates 34 are threaded at equal intervals at the bottom of the annular water chamber 31, which makes the coverage area of the external component 1 under spray cooling wider. At the same time, when a single spray plate 34 fails, the spray plate 34 can be unscrewed from the bottom of the annular water chamber 31 through the inlet pipe 35.
[0029] When the cooling water is sprayed onto the surface of the water-cooled furnace body 11, it flows down along the outer shell of the water-cooled furnace body 11 and into the lower hanging slot 13. At this time, the cooling water in the lower hanging slot 13 can be returned to the cooling box 22 through the return pipe 24 by the second water pump 241 and then cooled again by the cooling box 22. The above completes the cooling water circulation work.
[0030] The working principle and usage process of this utility model are as follows:
[0031] After inserting the two sets of annular water tanks 31 into the annular groove 121 at the top of the upper hanging plate 12, the two sets of annular water tanks 31 can be fixedly installed on the upper hanging plate 12 using bolts 33 and nuts 331 at the mounting plate 321.
[0032] Cooling water is injected into the cooling tank 22 through the inlet 221. The first water pump 231 is started so that the cooling water in the cooling tank 22 can enter the annular water chamber 31 through the discharge pipe 23, and flow to the inlet pipe 35 and the spray plate 34 respectively until it is sprayed from the spray head 341 to the outside of the water-cooled furnace body 11 to complete the cooling. The spray plates 34 are threaded at equal intervals at the bottom of the annular water chamber 31 so that the area of the external component 1 is covered by the spray cooling area is wider. At the same time, when a single spray plate 34 fails, the spray plate 34 can be unscrewed from the bottom of the annular water chamber 31 through the inlet pipe 35.
[0033] When the cooling water is sprayed onto the surface of the water-cooled furnace body 11, it flows down along the outer shell of the water-cooled furnace body 11 and into the lower hanging slot 13. At this time, the cooling water in the lower hanging slot 13 can be returned to the cooling box 22 through the return pipe 24 by the second water pump 241 and then cooled again by the cooling box 22. The above completes the cooling water circulation work.
[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
