Description

Technical Field

[0001] This invention relates to the field of titanium slag smelting furnace equipment technology, specifically to a reinforced water-cooled furnace cover assembly for a titanium slag smelting furnace. Background Technology

[0002] In high-temperature smelting conditions, the furnace cover of a titanium slag smelting furnace is subjected to radiant and conductive heat of thousands of degrees Celsius for extended periods, creating an extremely harsh working environment. Currently, the industry commonly uses water-cooled furnace covers, whose core cooling method involves installing water-cooling coils inside or around the furnace cover. Cooling water inside the coils carries away the heat absorbed by the furnace cover, thereby controlling the furnace cover temperature and preventing deformation and damage.

[0003] The existing furnace cover has an imperfect insulation structure design, and a large amount of radiant and conductive heat inside the furnace is directly transferred to the water-cooled coil. As a result, a large part of the heat carried away by the cooling water is ineffective heat load, which not only reduces the effective utilization rate of the cooling system, but also requires increasing the cooling water flow rate and pressure, thus increasing the equipment operating cost and energy consumption.

[0004] Therefore, in response to the problems of insufficient cooling efficiency, uneven heat exchange, and high heat load of existing water-cooled furnace covers for titanium slag smelting furnaces, there is an urgent need for a new type of furnace cover structure that can enhance heat transfer, improve cooling efficiency, and reduce ineffective heat load, so as to solve the above-mentioned technical defects and improve the reliability and service life of the furnace cover. Summary of the Invention

[0005] The purpose of this invention is to provide a reinforced water-cooled furnace cover assembly for a titanium slag smelting furnace, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A reinforced water-cooled furnace cover assembly for a titanium slag smelting furnace includes a furnace cover base, a furnace cover body fixedly installed on the top of the furnace cover base, a water-cooling coil arranged around the outer side of the furnace cover body, a heat transfer device fixedly installed on the right side of the furnace cover body, a transmission pipe fixedly connected to one end of the heat transfer device, and the other end of the transmission pipe movably sleeved on the top of the furnace cover body. Also includes: A heat transfer mechanism is disposed inside the furnace cover body to assist the furnace cover body in improving heat dissipation efficiency. A cleaning mechanism is installed at the output end of the heat transfer device and is used for cleaning the inside of the water-cooled pipes.

[0007] Preferably, the heat transfer mechanism includes a heat transfer plate, the bottom of which has a snap-fit ​​groove, the top of which has a heat dissipation hole, a grid heat dissipation plate fixedly installed on the top of the heat transfer plate, and an auxiliary heat dissipation plate fixedly sleeved on the top of the grid heat dissipation plate.

[0008] Preferably, a cooling fan is fixedly installed inside the auxiliary heat sink, and a protective plate is fixedly installed at the bottom of the inner cavity of the auxiliary heat sink, with the protective plate located below the cooling fan.

[0009] Preferably, a heat transfer substrate is fixedly installed on the top of the inner cavity of the furnace cover body, a base is fixedly installed on the top of the heat transfer substrate, a cooling pipe is fixedly installed on the top of the base, and the top of the cooling pipe is disposed inside the snap-fit ​​groove.

[0010] Preferably, the output end of the cooling coil is fixedly connected to a connecting pipe, and the other end of the connecting pipe is movably sleeved with an inner ring plate.

[0011] Preferably, multiple bases are provided on the top of the heat transfer substrate, and the bases are evenly distributed in a ring.

[0012] Preferably, the cleaning mechanism includes a cooling output pipe, one end of which is detachably installed inside the heat transfer device, and the other end of which is connected to the cooling pipe.

[0013] Preferably, a connecting shaft is movably mounted at the connecting end of the cooling output pipe, a rotating shaft is movably mounted inside the connecting shaft, a transmission gear shaft is fixedly mounted on the outer side of the rotating shaft, a drive gear is meshed on the outer side of the transmission gear shaft, and a drive motor is fixedly connected inside the drive gear.

[0014] Preferably, a connecting rod is fixedly installed on the inner side of the rotating shaft, a rotating column is fixedly connected to the other end of the connecting rod, an auxiliary frame is fixedly connected to the bottom of the rotating column, a scraper is fixedly connected to the other end of the auxiliary frame, and the other side of the scraper is disposed on the inner wall of the cooling output pipe.

[0015] Preferably, a sealing ring is fixedly installed at the connection between the connecting shaft and the rotating shaft, and a sealing outer ring is fixedly installed on the inner side of the connecting shaft.

[0016] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows: 1.

[0021] The present invention will be further described in detail below with reference to embodiments: like Figure 1-5 As shown, the present invention has the following three specific embodiments.

[0022] Example 1 The present invention provides a reinforced water-cooled furnace cover assembly for a titanium slag smelting furnace, comprising a furnace cover base 1, a furnace cover body 2 fixedly installed on the top of the furnace cover base 1, a water-cooled coil 3 arranged around the outside of the furnace cover body 2, a heat transfer device 4 fixedly installed on the right side of the furnace cover body 2, a transmission pipe 5 fixedly connected to one end of the heat transfer device 4, and the other end of the transmission pipe 5 movably sleeved on the top of the furnace cover body 2. Also includes: The heat transfer mechanism is located inside the furnace cover body 2 and is used to assist the furnace cover body 2 in improving heat dissipation efficiency. The cleaning mechanism is located at the output end of the heat transfer device 4 and is used for cleaning the inside of the water-cooled pipes.

[0023] like Figure 1 As shown, the furnace cover base 1 serves as the mounting foundation for the entire furnace cover assembly, providing fixed support for the furnace cover body 2. This ensures the furnace cover body 2 is stably installed on top of the smelting furnace, preventing the high temperature inside the furnace from being directly conducted to other parts of the furnace. The furnace cover body 2 is in direct contact with the high-temperature environment inside the furnace, bearing a large amount of radiant and conductive heat generated during the smelting process. The water-cooled coils 3 surrounding the outside of the furnace cover body 2 are the main heat dissipation components. During operation, the cooling medium continuously circulates inside the water-cooled coils 3. When the furnace cover body 2 absorbs the high temperature inside the furnace, the heat is quickly conducted to the water-cooled coils 3 on the outside. Through the flow of the cooling medium, the heat is carried away and discharged from the furnace cover assembly, thereby reducing the temperature of the furnace cover body 2. The heat transfer device 4, which is fixedly installed on the right side of the furnace cover body 2, works in conjunction with the transmission pipe 5 fixedly connected to one end, and works with the heat transfer mechanism inside the furnace cover body 2 to form an auxiliary heat transfer system. The heat transfer mechanism is located inside the furnace cover body 2, which can quickly absorb the heat inside the furnace cover body 2 and reduce the accumulation of heat inside the furnace cover body 2. Subsequently, the heat transfer mechanism transfers the absorbed heat to the heat transfer device 4. The heat transfer device 4 further conducts the heat through the transmission pipe 5, transferring the heat to the water cooling system or external heat dissipation structure, further improving the heat dissipation efficiency of the entire furnace cover, making up for the insufficient heat dissipation of the single water cooling coil 3, and achieving enhanced cooling effect. The cleaning mechanism is located at the output end of the heat transfer device 4. Its core function is to clean the water cooling system internally. Due to the long-term circulation of the cooling medium, scale and impurities may accumulate inside the pipes, leading to a decrease in pipe smoothness, affecting the flow efficiency of the cooling medium, and thus reducing the heat dissipation effect. The cleaning mechanism can clean the inside of the water cooling pipes periodically or according to operational needs, removing scale and impurities, ensuring smooth circulation of the cooling medium, ensuring stable heat dissipation effect of the main water cooling system and auxiliary heat transfer system, and extending the service life of the entire furnace cover assembly.

[0024] Example 2 The difference from Embodiment 1 is that this embodiment discloses a heat transfer mechanism including a heat transfer plate 434, a snap-fit ​​groove at the bottom of the heat transfer plate 434, a heat dissipation hole 435 at the top of the inner cavity of the snap-fit ​​groove, a grid heat dissipation plate 433 fixedly installed on the top of the heat transfer plate 434, an auxiliary heat dissipation plate 43 fixedly sleeved on the top of the grid heat dissipation plate 433, a cooling fan 431 fixedly installed inside the auxiliary heat dissipation plate 43, a protective plate 432 fixedly installed at the bottom of the inner cavity of the auxiliary heat dissipation plate 43, the protective plate 432 being located below the cooling fan 431, a heat transfer substrate 42 fixedly installed on the top of the inner cavity of the furnace cover body 2, a base 46 fixedly installed on the top of the heat transfer substrate 42, a cooling pipe 45 fixedly installed on the top of the base 46, the top of the cooling pipe 45 being disposed inside the snap-fit ​​groove, a connecting pipe 44 fixedly connected to the output end of the cooling pipe 45, and an inner ring plate 47 movably sleeved at the other end of the connecting pipe 44, and a cleaning mechanism. The device includes a cooling output pipe 41, one end of which is detachably installed inside the heat transfer device 4, and the other end of which is connected to the cooling pipe 45. A connecting shaft 48 is movably installed at the connecting end of the cooling output pipe 41, and a rotating shaft 411 is movably installed inside the connecting shaft 48. A transmission gear shaft 412 is fixedly installed on the outside of the rotating shaft 411, and a drive gear 417 is meshed on the outside of the transmission gear shaft 412. A drive motor 418 is fixedly connected inside the drive gear 417. A connecting rod 413 is fixedly installed on the inside of the rotating shaft 411, and a rotating column 414 is fixedly connected to the other end of the connecting rod 413. An auxiliary frame 415 is fixedly connected to the bottom of the rotating column 414, and a scraper 416 is fixedly connected to the other end of the auxiliary frame 415. The other side of the scraper 416 is disposed on the inner wall of the cooling output pipe 41. Multiple bases 46 are provided on the top of the heat transfer substrate 42, and the bases 46 are evenly distributed in a ring.

[0025] like Figure 2 , 3As shown in Figure 4, the heat transfer substrate 42 first absorbs the high-temperature heat inside the furnace cover body 2 and transfers it to the cooling pipes 45 on the base 46. The cooling pipes 45 conduct the heat to the snap-fit ​​groove, and then through the heat transfer plate 434 and heat dissipation holes 435 to the grid heat dissipation plate 433, which assists the cooling fan 431 inside the heat dissipation plate 43 to accelerate heat dissipation and reduce heat accumulation inside the furnace cover body 2. Subsequently, the heat transfer mechanism transfers the absorbed heat to the heat transfer device 4. The heat transfer device 4 further conducts the heat through the transmission pipe 5, transferring the heat to the water cooling system or external heat dissipation structure, further improving the heat dissipation efficiency of the entire furnace cover, making up for the insufficient heat dissipation of the single water cooling coil 3, and achieving enhanced cooling effect. In addition, due to the cooling medium During long-term circulation, scale and impurities may accumulate inside the pipes, reducing pipe flow and affecting the efficiency of cooling medium flow, thus reducing heat dissipation. When the cleaning mechanism is working, the drive motor 418 drives the drive gear 417 to rotate. The drive gear 417 meshes with the transmission gear shaft 412, which drives the rotating shaft 411 to rotate within the connecting shaft 48. The rotating shaft 411 drives the scraper 416 to rotate on the inner wall of the cooling output pipe 41 through the connecting rod 413, rotating column 414, and auxiliary frame 415, scraping away scale and impurities from the inner wall of the pipe. The cleaning mechanism can be activated periodically or as needed to ensure smooth circulation of the cooling medium, maintain stable heat dissipation of the main water cooling system and auxiliary heat transfer system, and extend the service life of the entire furnace cover assembly.

[0026] Example 3 The difference from Embodiment 2 is that this embodiment discloses that a sealing ring 481 is fixedly installed at the connection between the connecting shaft 48 and the rotating shaft 411, and a sealing outer ring 482 is fixedly installed on the inner side of the connecting shaft 48.

[0027] like Figure 5 As shown, a sealing ring 481 is fixedly installed at the connection between the connecting shaft 48 and the rotating shaft 411, and a sealing outer ring 482 is fixedly installed on the inner side of the connecting shaft 48. The sealing ring 481 can prevent the cooling medium from leaking from the connection between the connecting shaft 48 and the rotating shaft 411, and the sealing outer ring 482 further enhances the sealing effect and ensures the sealing performance of the cleaning mechanism during operation.

[0028] The working principle of the reinforced water-cooled furnace cover assembly of the titanium slag smelting furnace will be explained in detail below.

[0029] like Figure 1-5As shown, the furnace cover base 1 serves as the mounting foundation for the entire furnace cover assembly, providing fixed support for the furnace cover body 2. This ensures the furnace cover body 2 is stably installed on top of the smelting furnace, preventing direct heat transfer from the furnace interior to other parts of the furnace. The furnace cover body 2 directly contacts the high-temperature environment inside the furnace, bearing the large amount of radiant and conductive heat generated during the smelting process. The water-cooled coils 3 surrounding the outer side of the furnace cover body 2 are the main heat dissipation components. The heat transfer base plate 42 first absorbs the high-temperature heat inside the furnace cover body 2 and transfers it to the cooling pipes 45 on the base 46. The cooling pipes 45 then conduct the heat to the snap-fit ​​groove, and then through the heat transfer plate 434 and heat dissipation holes 435 to the grid heat dissipation plate 433. The cooling fan 431 inside the auxiliary heat dissipation plate 43 accelerates heat dissipation and reduces heat accumulation inside the furnace cover body 2. Subsequently, the heat transfer mechanism transfers the absorbed heat to the heat transfer device 4, which further conducts the heat through the transmission pipe 5. Heat is transferred to the water cooling system or external heat dissipation structure to further improve the heat dissipation efficiency of the entire furnace cover, making up for the insufficient heat dissipation of the single water cooling coil 3 and achieving enhanced cooling effect. In addition, due to the long-term circulation of the cooling medium, scale and impurities may accumulate inside the pipes, leading to a decrease in pipe flow and affecting the flow efficiency of the cooling medium, thereby reducing the heat dissipation effect. When the cleaning mechanism is working, the drive motor 418 drives the drive gear 417 to rotate. The drive gear 417 meshes with the transmission gear shaft 412, driving the rotating shaft 411 to rotate inside the connecting shaft 48. The rotating shaft 411 drives the scraper 416 to rotate on the inner wall of the cooling output pipe 41 through the connecting rod 413, rotating column 414, and auxiliary frame 415, scraping away the scale and impurities on the inner wall of the pipe. The cleaning mechanism can be activated periodically or according to operating needs to ensure smooth circulation of the cooling medium, ensure stable heat dissipation effect of the main water cooling system and auxiliary heat transfer system, and extend the service life of the entire furnace cover assembly.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
