Description

Technical Field

[0001] This utility model relates to the field of converter water-cooled hole expansion, specifically, to a converter water-cooled hole expander. Background Technology

[0002] In converter steelmaking, the maintenance quality of the taphole has a significant impact on the quality of molten steel and various technical and economic indicators. To improve these indicators, current methods mainly focus on optimizing the performance (including quality and efficiency) of the taphole expander and improving the taphole replacement process.

[0003] However, traditional converter taphole expander tools have significant limitations in practical applications. After steelmaking, the temperature at the taphole is extremely high. Performing expander operations at this time severely impacts the expander tools due to the high-temperature environment. This high temperature causes a rapid decline in the material properties of the tools, leading to accelerated wear, deformation, and even damage, thus significantly shortening the service life of the expander. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a converter water-cooled expansion device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A converter water-cooled expander includes an expander mounting bracket, an expander mounting assembly installed inside the expander mounting bracket, a circulating water cooling assembly on one side of the expander mounting bracket, and a coolant replacement assembly on one side of the circulating water cooling assembly.

[0007] To achieve the function of circulating water cooling, the circulating water cooling assembly includes a coolant storage shell, which is connected to an expansion joint mounting bracket. A semiconductor cooling fin is embedded in the inner wall of the coolant storage shell, with the cold end of the fin located inside the shell and the hot end exposed to the outside air. A suction pipe is connected to one side of the coolant storage shell, and a suction pump is connected to one end of the pipe. A pump support frame is connected to the bottom of the pump, and the support frame is fixedly connected to the coolant storage shell. A multi-channel drain pipe is connected to the pump's output end, and a cooling nozzle is connected to its output end. A pipe connecting plate is connected to the periphery of the drain pipe, and a tension plate is movably connected to one side of the pipe connecting plate. A central hole sleeve is connected to one side of the tension plate, and a rotating crankshaft is movably fitted inside the sleeve. A spray support frame is movably connected to the periphery of the crankshaft, and the pipe connecting plate and the spray support frame are in sliding fit. The spray support frame is connected to the coolant storage shell, and a drive motor is connected to one end of the crankshaft.

[0008] Furthermore, a water-cooled splash guard is connected to the periphery of the coolant storage shell.

[0009] Furthermore, a controller is provided on one side of the coolant storage housing, and the semiconductor cooling plate and the controller are electrically connected.

[0010] Furthermore, in order to achieve the function of mounting the reamer, it includes a reaming rotating shaft, which is movably mounted inside a rotating shaft mounting plate. The rotating shaft mounting plate and the reamer mounting bracket are respectively provided with bolt slots, and high-temperature resistant bolts are fitted inside the bolt slots. A water-cooling flow groove is provided inside the reaming rotating shaft. One end of the reaming rotating shaft is connected to a reaming motor, and the housing of the reaming motor is connected to the reamer mounting bracket. The end of the reaming rotating shaft away from the reaming motor is connected to a reaming drill bit.

[0011] Furthermore, the enlarged hole motor and controller are electrically connected.

[0012] Furthermore, in order to achieve the function of coolant replacement, the coolant replacement component includes an observation mounting slot, which is located inside the coolant storage housing. An observation glass is installed inside the observation mounting slot. A replacement drain pipe is connected to one side of the coolant storage housing, and a drain valve is installed inside the replacement drain pipe.

[0013] Furthermore, the drain valve and controller are electrically connected.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) This utility model has made improvements to the existing technology. In actual use, the circulating water cooling component cools the reamer tool by reciprocating spraying, which solves the problem that the traditional converter tapping reamer tool is damaged and its service life is reduced when the tapping temperature is very high after steel smelting.

[0016] (2) In actual use, when working, the reaming motor drives the reaming rotating shaft to rotate at high speed, driving the reaming drill bit to carry out mechanical reaming operation on the converter. The water-cooled flow through the groove allows the coolant to flow through the reaming rotating shaft, and the coolant and the reaming rotating shaft exchange heat fully. When disassembly and replacement are required, the high-temperature resistant bolts are unscrewed through the bolt groove with a wrench, and the rotating shaft mounting plate is removed for easy disassembly and replacement.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] According to an embodiment of the present invention, a converter water-cooled expander is provided. The expander mounting bracket 1 has an expander mounting assembly 2 installed inside it. A circulating water cooling assembly 3 is provided on one side of the expander mounting bracket 1, and a coolant replacement assembly 4 is provided on one side of the circulating water cooling assembly 3.

[0026] like Figure 1-4As shown, according to an embodiment of the present invention, a converter water-cooled expander includes a circulating water-cooling assembly 3 comprising a coolant storage housing 301, which is welded to the side of the expander mounting bracket 1. The inner cavity of the housing is filled with a cooling medium, such as a water-based coolant. A semiconductor cooling plate 302 is embedded in the inner wall of the coolant storage housing 301, with its cold end exposed inside the housing and in direct contact with the coolant, and its hot end extending into the outside air to dissipate heat. One end of a liquid extraction pipe 303 is inserted into the bottom of the coolant storage housing 301, and the other end is connected to the inlet of a liquid extraction pump 304. The pump 304 is bolted to the outer wall of the coolant storage housing 301 via a pump body support frame 305 at the bottom. The outlet of the pump 304 is connected to a multi-channel drain pipe 306. A pipe connecting plate 308 is connected to the periphery of the multi-channel drain pipe 306. A tension plate 309 is movably connected to one side of the pipe connecting plate 308. A central hole sleeve 310 is connected to one side of the tension plate 309. A rotating crankshaft 311 is movably fitted inside the central hole sleeve 310. A spray support frame 312 is movably connected to the periphery of the rotating crankshaft 311. The pipe connecting plate 308 and the spray support frame 312 are slidably fitted. The spray support frame 312 is connected to the coolant storage housing 301. A drive motor 313 is connected to one end of the rotating crankshaft 311. Through the above technical solution, after the semiconductor cooling plate 302 is energized, it continuously cools the coolant in the coolant storage shell 301. The pump 304 pumps the low-temperature coolant into the multi-channel drain pipe 306 through the pumping pipe 303. The coolant forms a mist jet through the cooling nozzle 307, which accurately covers the surface of the high-temperature reaming drill bit 203. The coolant, after absorbing heat, naturally flows back to the coolant storage shell 301 and is recooled by the semiconductor cooling plate 302 to form a closed loop. At the same time, the drive motor 313 drives the rotating crankshaft 311 to rotate in the spray support frame 312. When the rotating crankshaft 311 rotates, it can drive the tension plate 309 to move through the central sleeve 310. The tension plate 309 drives the pipe connecting plate 308 to reciprocate in the spray support frame 312, thereby driving the cooling nozzle 307 to reciprocate, making the cooling effect of the reaming rotating shaft 201 better.

[0027] like Figure 1-4As shown, according to an embodiment of the present invention, a converter water-cooled expander has an expander mounting assembly 2 as the core power unit, including an expanding rotary shaft 201. The expanding rotary shaft 201 is movably mounted inside a rotary shaft mounting plate 205. Bolt grooves 206 are respectively provided inside the rotary shaft mounting plate 205 and the expander mounting bracket 1. High-temperature resistant bolts 207 are fitted inside the bolt grooves 206. A water-cooling flow groove 204 is provided inside the expanding rotary shaft 201. An expanding motor 202 is connected to one end of the expanding rotary shaft 201. The housing of the expanding motor 202 is connected to the expander mounting bracket 1. An expanding drill bit 203 is connected to the end of the expanding rotary shaft 201 away from the expanding motor 202. With the above technical solution, during operation, the reaming motor 202 drives the reaming rotating shaft 201 to rotate at high speed, driving the reaming drill bit 203 to perform mechanical reaming operation on the converter. The water-cooled flow channel 204 allows the coolant to flow through the reaming rotating shaft 201, and the coolant and the reaming rotating shaft 201 exchange heat fully. When disassembly and replacement are required, the high-temperature resistant bolt 207 is unscrewed through the bolt groove 206 with a wrench, and the rotating shaft mounting plate 205 is removed for easy disassembly and replacement.

[0028] like Figure 1-4 As shown in the figure, according to an embodiment of the present invention, a converter water-cooled expansion device includes a coolant replacement assembly 4 comprising an observation mounting slot 401, which is formed on the side wall of the coolant storage housing 301. A pressure-resistant observation glass 402 is embedded in the slot for real-time monitoring of the coolant level and cleanliness. A replacement drain pipe 403 is welded to the bottom of the housing, and an electrically controlled drain valve 404 is installed in the pipe for periodically discharging waste liquid. Through this technical solution, the user can monitor the coolant status through the observation glass 402 and trigger the drain valve 404 to replace the medium via the controller 5. The water-cooled splash guard 6 effectively blocks splashing droplets, ensuring operational safety.

[0029] In one embodiment, the water-cooled flow channel 204 can also be configured as a spline shaft or other similar design, and different styles can be designed as needed, as long as the water is retained.

[0030] During operation, the reaming motor 202 drives the reaming rotary shaft 201 to mechanically ream the hole using the reaming drill bit 203. Simultaneously, the semiconductor cooling plate 302 is activated for cooling, and the liquid pump 304 circulates the coolant. Low-temperature coolant is continuously sprayed onto the surface of the reaming rotary shaft 201 for cooling. The heated coolant then flows back to the coolant storage shell 301 for recooling. Users can monitor the coolant status through the observation glass 402 and trigger the drain valve 404 via the controller 5 to replace the coolant. The water-cooled splash guard 6 effectively blocks splashing droplets, ensuring operational safety.

[0031] 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.
