Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0027] Reference Figures 1-7 This utility model provides an embodiment of a steel pipe cooling water spray system, including a base 1, which serves as the installation foundation for the entire system. Made of high-strength steel, it possesses excellent load-bearing capacity and stability. A placement plate 3 is fixedly connected to the left side of the base 1, forming a left-side support structure. This structure, together with the right-side placement frame 17, bears the weight of the crossbeam 5 and the spray components, ensuring a balanced force distribution across the system. Support columns 4 are fixedly connected to the top side of the placement plate 3, forming a three-dimensional support network that evenly distributes the weight of the crossbeam 5 and the spray components to the base 1, preventing excessive local stress and deformation. A placement frame 17 is fixedly connected to the right side of the base 1. Its high-strength design can withstand the vibration of the servo motor 18 during operation, while providing precise installation positioning for the driven wheel 20 and the drive rod 16, ensuring stable operation of the transmission system. Multiple evenly distributed support columns 4 are fixedly connected to the top sides of both the placement frame 17 and the placement plate 3. Crossbeams 5, possessing high bending strength, are fixedly connected to the top sides of the support columns 4. To provide structural support for the overall spraying system, a support rod 7 is fixedly connected to the inner side of the crossbeam 5, providing top support for the spray pipe 8. A fixing plate 9 is fixedly connected to the outer side of the crossbeam 5, and the spray pipe 8 is fixedly connected to the bottom side of the support rod 7. A sliding groove 31 is provided on the bottom side of the support rod 7, and the top side of the spray pipe 8 is slidably connected to the inner side of the sliding groove 31. The spray pipe 8 sliding in the groove can accurately adjust its relative position with the steel pipe to ensure all-round spraying coverage. The spray pipe 8 adopts a double spiral spray pipe with a hollow interior for conveying cooling water. Multiple evenly distributed fan-shaped nozzles 13 are fixedly connected to the inner side of the top of the spray pipe 8. The fan-shaped nozzles 13 are made of 316L stainless steel casting, with a spray angle of 60° and a flow coefficient of 0.85. They have good atomization effect and uniform water flow distribution, which can quickly reduce the surface temperature of the steel pipe and avoid local overheating. Multiple evenly distributed conical nozzles 12 are fixedly connected to the inner side of the bottom of the spray pipe 8. The water flow impact force is strong and can penetrate into the fine textures and gaps on the surface of the steel pipe to enhance the cooling effect. The conical spray can specifically cool the lower surface of the steel pipe and the part that contacts the idler roller 11, making up for insufficient heat dissipation in the contact area.

[0028] Reference Figure 1 and Figure 2The base 1 has side plates 2 fixedly connected to both sides, which are welded from steel plates. Internal rotating grooves are reserved for installing sliding rods 10. The sliding rods 10 are rotatably connected inside the side plates 2 to maximize steam absorption efficiency and reduce the impact of steam on the equipment and operating environment. Wing plates 6 are fixedly connected to the outer periphery of the sliding rods 10, allowing for angle adjustment as the sliding rods 10 rotate. This provides stable support for the filter frame 24 and expands the steam absorption range through angle adjustment, efficiently treating the steam generated during spraying. An exhaust frame 25 is fixedly connected to the inner rear end of the wing plate 6, guiding the steam to form a stable flow path within it, facilitating the smooth discharge of steam generated by the fan blades. Its robust structure also ensures the stability of the entire exhaust system during operation. A fixing frame 27 is fixedly connected to the inner side of the exhaust frame 25 to ensure that the drive end of the motor 26 can... The rotating rod 30 is stably driven to operate, providing a reliable power support foundation for the normal operation of the exhaust fan. The motor 26 is fixedly connected to the inner side of the fixed frame 27, which can meet the wind power requirements of the exhaust and ensure that there is enough power to discharge the steam in time. The rotating rod 30 is fixedly connected to the drive end of the motor 26 to withstand the torque and centrifugal force generated during the rotation, ensuring the efficiency and stability of power transmission. The fan blade shaft 28 is fixedly connected to the outer periphery of the rotating rod 30, and the fan blades are installed to generate wind power for exhausting the steam efficiently. The fan blade shaft 28 is rotatably connected to both sides of the fan blade frame 28, providing reliable support for the normal rotation of the fan blades. The outer side of the fan blade frame 29 is fixedly connected to the inner side of the exhaust frame 25. The filter frame 24 is fixedly connected to the inner side of the front end of the wing plate 6 to prevent impurities from causing wear, blockage or damage to these components, thereby ensuring the long-term stable operation of the exhaust system.

[0029] Reference Figures 1-7Multiple evenly distributed roller frames 15 are fixedly connected to the top side of the base 1. These roller frames 15 are arranged along the steel pipe conveying direction to ensure the axis of the idler rollers 11 remains parallel, preventing deviation during steel pipe conveying. A movable wheel 14 is rotatably connected to the inner side of each roller frame 15. This wheel is wear-resistant and lightweight, transmitting power from the drive rod 16 to the idler rollers 11 for stable steel pipe conveying. Idler rollers 11 are rotatably connected to the outer circumference of the movable wheel 14, driving the steel pipe to rotate. The polyurethane-coated idler rollers 11 reduce friction damage to the steel pipe surface and lower noise during conveying. The polyurethane idler rollers 11 have a hardness of HS80±5 and axial drainage grooves on their surface. A servo motor 18 is fixedly connected to the top side of the placement frame 17. The servo motor 18 is a 750W AC servo motor with a rated torque of 4.8 N·m. It has high operating accuracy and can stably provide power, ensuring uniform steel pipe conveying speed and meeting the conveying rhythm requirements of different cooling processes. A drive wheel 19 is fixedly connected to the drive end of the servo motor 18. Multiple evenly distributed rollers 14 are meshed around the outer circumference of the drive wheel 19. Distributed driven wheels 20, through gear meshing, drive multiple driven wheels 20 to rotate synchronously. A drive rod 16 is fixedly connected to the inner side of each driven wheel 20, with both ends supported by bearings, ensuring high rotational precision and guaranteeing synchronous operation of the idler rollers 11, preventing jamming during steel pipe conveying. The rear end of the drive rod 16 is fixedly connected to the outer periphery of the idler roller 11. A main wheel frame 22 is fixedly connected to the top side of the placement frame 17, and multiple evenly distributed driven wheel frames 21 are fixedly connected to the inner side of the placement frame 17. The main wheel frame 22 is rotatably connected to the outer side of the drive wheel 19. The wheel frame 21 is rotatably connected to the outside of the driven wheel 20. The frame is made by casting process, which has good structural rigidity and can effectively limit the axial movement of the gear and ensure the stability of the transmission system. A water guide groove is opened on the top side of the middle part of the base 1. The water guide groove has an inclination angle of 8°. A spiral separator 23 is fixedly connected to the inside of the base 1. The separated clean water can be re-transported to the spray pipe 8 for recycling, which reduces water waste and avoids impurities clogging the nozzles and affecting the cooling effect. The water inlet at the front of the spiral separator 23 is fixedly connected to the inside of the water guide groove.

[0030] Working principle: First, the steel pipe to be cooled is placed on the idler roller 11 at the inlet. The polyurethane coating on its outer circumference provides initial positioning of the steel pipe, preventing it from shifting during startup. After receiving the start signal, the servo motor 18 drives the drive wheel 19 to rotate. Through gear meshing, the drive wheel 19 transmits power to multiple driven wheels 20, causing them to rotate synchronously. The drive rod 16 inside the driven wheel 20 rotates along with it. Since the rear end of the drive rod 16 is connected to the idler roller 11, the idler roller 11 opens under the driving force. The system begins to rotate, simultaneously driving the steel pipe to rotate at multiple angles. When the steel pipe reaches below the spray pipe 8, the stable structure formed by the support column 4 and the crossbeam 5 provides reliable support for the spray pipe 8. External cooling water enters the spray pipe 8 through the pipe and is sprayed out through the top fan-shaped nozzle 13 and the bottom conical nozzle 12. The fan-shaped nozzle 13 covers the upper surface and sides of the steel pipe at multiple angles, achieving rapid cooling through atomized water flow. The conical nozzle 12 focuses on the lower surface of the steel pipe and the contact area with the roller 11, using strong impact force to compensate for the heat dissipation shortcomings in this area, achieving all-round cooling without dead angles.

[0031] While spraying and cooling, steam treatment is started simultaneously. The steam generated by the contact between the cooling water and the high-temperature steel pipe diffuses upward. At this time, the motor 26 inside the exhaust frame 25 drives the rotating rod 30 to start the exhaust fan, thereby effectively discharging the steam and preventing steam accumulation. The operator can adjust the angle of the wing plate 6 by rotating the sliding rod 10 so that the wing plate 6 is aligned with the area with higher steam concentration, thereby improving the absorption efficiency. The water after cooling treatment returns to the water guide trough in the middle along the base 1. The end of the water guide trough is connected to the spiral separator 23 to achieve wastewater treatment.
