Description
Technical Field
[0001] This utility model relates to the field of steel structure production technology, specifically a rapid cooling device for steel structure production. Background Technology
[0002] Steel structures are structures made of steel and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The various components or parts are typically connected by welds, bolts, or rivets. Currently, steel structures generally require cooling treatment during production.
[0003] A Chinese patent (publication number: CN221648824U) discloses a cooling device for steel structure production, including a support platform, a box body, and a cooling chamber. The box body is fixedly connected to the upper surface of the support platform, and the cooling chamber is located inside the box body. A transmission mechanism is installed inside the box body, including a transmission chamber. A forward and reverse motor is fixedly connected inside the transmission chamber, and a threaded column is fixedly connected to one end of the output shaft of the forward and reverse motor. In use, the steel structure is placed inside the box body, and a spray pipe is installed above the box body to cool the steel structure using water sprayed from the spray pipe. While this method has a certain cooling effect, the top of the steel structure comes into contact with the water first, leading to uneven temperature drop. The top of the steel structure is directly sprayed with water, resulting in a faster temperature drop, while the middle and lower parts cool more slowly, requiring a longer cooling time and resulting in a low cooling rate.

[0016] According to the above technical solution, the water stop valve is used to prevent water accumulation from affecting the airbag's expansion and contraction performance, thus ensuring the stable operation of the system.
[0017] Furthermore, a telescopic cylinder is connected to the inner top wall of the working box, and the telescopic end of the telescopic cylinder is connected to the top of the air collecting hood.

[0027] See Figure 1-4This embodiment is a rapid cooling device for steel structure production. The device includes a working box 1, a cooling box 2, and a rectangular water storage chamber 3. One side of the working box 1 is connected to the water storage chamber 3, and the drain end of the water storage chamber 3 extends into the water storage chamber 3 to supply water. A mounting frame 5 is connected to the working box 1, with its top connected to the bottom of the cooling box 2. A telescopic airbag 6 is connected inside the mounting frame 5, and a telescopic column 7 is connected to the top of the telescopic airbag 6. The other end of the telescopic column 7 extends into the cooling box 2. A return pipe 8 is connected to the side of the cooling box 2 away from the drain end of the water pump 4, and the other end of the return pipe 8 is connected to the telescopic airbag 6. The return pipe 8 is used to transport the steam generated by the evaporation of water in the water storage chamber 3 to the telescopic airbag 6, causing the telescopic airbag 6 to drive the telescopic column 7 to move vertically. It should be noted that, in order to facilitate the cooling of steel structures of different sizes and further enhance the cooling effect, a retractable heat pipe can be installed in the cooling box 2. The heat dissipation end is in contact with the steel structure, and the heat dissipation end can extend into the water storage chamber 3 for cooling operations. In specific implementation, the steel structure is placed in the cooling box 2. The heat emitted by the steel structure heats the water in the water storage chamber 3. The water evaporates and produces steam. The steam enters the telescopic air bladder 6 through the return pipe 8. As the steam accumulates, the pressure in the telescopic air bladder 6 increases, driving the telescopic column 7 to move upward and push the steel structure out of the cooling box 2 for easy removal later. The water pump 4 can supply water to the water storage chamber 3.
[0028] Furthermore, an exhaust fan 10 is connected to the top of the working box 1, and an air collecting hood 11 is installed inside the working box 1. The air collecting hood 11 is located above the cooling box 2, and the exhaust end of the exhaust fan 10 is connected to the air collecting hood 11. In specific implementation, the exhaust fan 10 is started, and the hot air generated above the steel structure is extracted through the air collecting hood 11 to accelerate the exhaust of hot air from the working box 1, reduce the temperature above the steel structure, and assist the overall cooling process. This setting can accelerate air circulation, make the heat transfer between the upper and lower parts of the steel structure more uniform, and effectively improve the cooling efficiency.
[0029] Furthermore, the exhaust end of the exhaust fan 10 is connected to a hot air delivery pipe 12, and the other end of the hot air delivery pipe 12 is connected to a winding pipe 13. The winding pipe 13 is wound around the return pipe 8, and the other end of the winding pipe 13 is connected to a hot air discharge pipe 19, which extends to the outside of the working box 1. In specific implementation, the hot air discharged by the exhaust fan 10 enters the winding pipe 13 through the hot air delivery pipe 12. The winding pipe 13 is wound around the return pipe 8, and the hot air exchanges heat with the steam in the return pipe 8. This setting can realize the secondary utilization of heat, using the hot air discharged by the exhaust fan 10 to heat the steam in the return pipe 8, enhancing the expansion power of the telescopic airbag 6, and ensuring that the telescopic column 7 is stably pushed out of the steel structure.
[0030] Furthermore, a one-way valve 9 is connected to the cooling tank 2, and the end of the return pipe 8 near the cooling tank 2 is connected to the one-way valve 9. In specific implementation, the steam generated in the water storage chamber 3 can enter the return pipe 8 through the one-way valve 9, but the steam or other substances in the return pipe 8 cannot flow back into the water storage chamber 3 of the cooling tank 2. This setting ensures one-way steam flow, prevents the steam in the return pipe 8 from flowing back into the water storage chamber 3, and avoids affecting the evaporation and cooling process of the water in the water storage chamber 3, ensuring stable air intake of the telescopic airbag 6.
[0031] Furthermore, the work box 1 has two symmetrical ventilation holes, and a blower 14 is connected to the ventilation holes; in specific implementation, after the two blowers 14 symmetrically arranged on the work box 1 are started, they blow air into the work box 1 to accelerate the air circulation inside the box and promote the dissipation of heat from the surface of the steel structure.
[0032] Furthermore, the bottom of the telescopic airbag 6 is connected to a drain pipe 17, one end of which extends to the outside of the working box 1 and is connected to a water stop valve 18. In specific implementation, after the steam inside the telescopic airbag 6 cools and liquefies to form water, the water stop valve 18 is opened, and the accumulated water is discharged from the working box 1 through the drain pipe 17. After the drainage is completed, the water stop valve 18 is closed. This setting can drain the accumulated water inside the telescopic airbag 6 and prevent the accumulated water from affecting the normal expansion and contraction performance of the telescopic airbag 6.
[0033] Furthermore, a telescopic cylinder 16 is connected to the inner top wall of the working box 1, and the telescopic end of the telescopic cylinder 16 is connected to the top of the air collecting hood 11. In specific implementation, by controlling the extension and retraction of the telescopic cylinder 16, the height of the air collecting hood 11 is adjusted so that it is closer to or further away from the top of the cooling box 2 according to the height of the steel structure and the cooling requirements, thereby optimizing the air extraction effect.
[0034] Furthermore, a water storage tank 15 is connected to one side of the working box 1, and a water pump 4 is connected to the top of the water storage tank 15. In specific implementation, the water storage tank 15 stores a large amount of cooling water, and the water pump 4 draws water from the water storage tank 15 and delivers it to the water storage chamber 3 of the cooling box 2 to provide a water source for the cooling process.
[0035] The working principle of this embodiment is as follows: Before use, the steel structure is placed in the water storage chamber 3 of the cooling box 2. The cooling water in the water storage tank 15 is continuously pumped to the water storage chamber 3 by the water pump 4 to form a certain water level. The heat of the steel structure heats the water in the water storage chamber 3. The water evaporates and generates steam. The latent heat of vaporization of the water absorbs the heat of the steel structure. The exhaust fan 10 extracts the hot air generated above the steel structure due to cooling through the air collector hood 11. The blowers 14 on both sides of the working box 1 start synchronously and blow air into the box, forming a bidirectional convection with the exhaust fan 10, accelerating the air flow on the surface of the steel structure, and further improving the heat dissipation efficiency. The steam generated in the water storage chamber 3 enters the return pipe 8 through the one-way valve 9. The one-way valve 9 prevents... Steam backflow affects the evaporation process. Steam enters the telescopic airbag 6 inside the mounting frame 5 along the return pipe 8. As steam accumulates, the pressure inside the airbag increases, driving the telescopic column 7 to move upward and gradually lift the steel structure. The hot air discharged by the exhaust fan 10 is introduced into the winding pipe 13 through the hot air delivery pipe 12. The winding pipe 13 is wrapped around the outside of the return pipe 8, using the hot air to exchange heat with the steam inside the return pipe 8, increasing the steam temperature and pressure, enhancing the expansion power of the telescopic airbag 6, and reducing the heat loss from the hot air discharge. When the steel structure cools to the target temperature, the steam pressure inside the telescopic airbag 6 reaches the set threshold, and the telescopic column 7 pushes the steel structure out of the water storage chamber 3 to the top of the working box 1, making it easy for operators to quickly retrieve materials.
