Description

Technical Field

[0001] The invention relates to the technical field of stainless steel pipe production, in particular to a cooling device used for stainless steel pipe production. Background Art

[0002] Stainless steel pipe is a kind of pipe with good corrosion resistance. It is mainly used in pipeline systems for transporting various liquids, gases and solids. Stainless steel pipe has excellent corrosion resistance, high strength and hardness, stable performance under high temperature environment, good processing performance, smooth and bright surface, not easy to rust and pollute, beautiful appearance, easy to clean and maintain. Stainless steel pipe is a pipe material with excellent performance and wide application. It is suitable for pipeline systems in chemical, petroleum, food, medicine, construction and other fields. In the production process of stainless steel pipes, different steel materials require different heat dissipation methods after welding. Austenitic stainless steel and 450°-850° stainless steel have intergranular corrosion. In order to avoid this temperature, they can be cooled immediately with water, while pearlite and martensitic stainless steel cannot be directly cooled by water. Stainless steel should be tempered after welding to allow it to cool slowly. In the production process of stainless steel pipes, they are usually cooled naturally by standing and cooled by fan wind. The standing cooling time cycle is too long. The wind generated by the fan during the fan wind cooling process may cause uneven heat dissipation effect. The temperature in some areas is too high or too low, which affects the strength and quality of the stainless steel pipe itself. Fan heat dissipation requires a lot of electricity to generate wind, which will increase the energy consumption cost in the production process. In response to the above problems, the inventor proposes a cooling device for stainless steel pipe production to solve the above problems. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention arranges a graphite heat dissipation component and a water circulation cooling component, so that the temperature of the stainless steel pipe itself is conducted to the water circulation cooling component through the graphite heat dissipation component, and the stainless steel pipe is cooled and dissipated for the first time through the water circulation cooling component. By arranging a water curtain cooling component, during the process of the heated circulating cooling water passing through the water curtain cooling component, a part of the circulating cooling water evaporates and absorbs heat in the air under the action of the water curtain cooling component, and the stainless steel pipe is cooled and dissipated for the second time, and the remaining circulating cooling water is cooled under the action of the water curtain cooling component, and the cooled circulating cooling water is returned to the water tank for recycling. Through the above operation, the effects of secondary segmented cooling of the stainless steel pipe and cooling and refluxing the heated circulating cooling water are achieved, so that the stainless steel pipe can dissipate heat evenly and effectively, and the circulating cooling water can be fully utilized while being cooled and refluxing, thereby improving the cooling efficiency, reducing the energy consumption required for cooling, and reducing the cooling cost; 2. The present invention sets a graphite heat dissipation component and a water circulation cooling component. The high temperature of the stainless steel pipe itself is conducted to the circulation cooling pipe through the graphite heat conduction frame, so that the temperature of the circulating cooling water in the circulation cooling pipe rises. The temperature of the graphite heat conduction frame is conducted and cooled by the circulating cooling water, thereby cooling the stainless steel pipe. The heated circulating cooling water moves to the curved heat dissipation pipe, and the circulating cooling water is cooled for the first time by heat conduction to the air. The above operation achieves the effect of cooling and dissipating the heat of the stainless steel pipe, dissipates the heat of the stainless steel pipe evenly and effectively, and avoids the influence of the uniform heat dissipation of the stainless steel pipe on its own quality and strength during the heat dissipation process; 3. The present invention provides a water curtain cooling component, so that the heated circulating cooling water is transported to the drain pipe and then discharged to the inner wall of the arc-shaped top frame through the drain hole opened on the drain pipe. The circulating cooling water falls to the top of the water curtain guide plate under the action of its own gravity and moves downward along the water curtain guide plate. In the process of the circulating cooling water falling, a part of the circulating cooling water will evaporate in the air and absorb the heat in the air, thereby reducing the surface temperature of the water curtain guide plate. The temperature of the water curtain guide plate will diffuse to the surroundings and reduce the temperature of the surrounding environment, thereby cooling the stainless steel pipe for the second time. The remaining circulating cooling water is cooled in the process of falling along the water curtain guide plate, and the cooled circulating coolant flows back to the water tank. Through the above operation, the stainless steel pipe is cooled for the second time and the heated circulating coolant is cooled and refluxed at the same time, thereby reducing the waste of water resources in the cooling process, reducing energy consumption and reducing production costs.

[0035] By adopting the above technical solution, the arc-shaped top frame 711 and the water baffle 712 prevent the circulating cooling water discharged from the drain pipe 703 from splashing.

[0037] By adopting the above technical solution, the curved heat dissipation pipe 608 is fixedly mounted on the connecting frame 301 through the fixing frame 302 .

[0038] Working principle: First, connect the water injection valve 9 to the external water injection pipe, and inject water into the water tank 5. After the welding and tempering, the stainless steel pipe is driven by the external traction device to move to the heat conduction frame 401 and pass through the graphite heat conduction frame 402. After passing through the graphite heat conduction frame 402, the stainless steel pipe enters the corresponding guide frame 801 on the second fixed bracket 3 and moves under the guidance of the guide roller 802; At this time, the pressure water pump 606 is controlled to be turned on. The circulating cooling water in the water tank 5 enters the corresponding circulating cooling pipe 601 through the water inlet pipe 605 and the water inlet valve 603 under the action of the pressure water pump 606. The circulating cooling water circulates in the circulating cooling pipe 601 and the connecting pipe 602 and is discharged from the water outlet valve 604. The discharged circulating cooling water is respectively discharged into the two curved heat dissipation pipes 608 through the double-pass pipe 607. After the tempering is completed, the stainless steel pipe increases the temperature of the surrounding air under the action of heat conduction. In the process of the stainless steel pipe passing through the graphite heat conducting frame 402, the air temperature of the graphite heat conducting frame 402 rises. Under the action of the high thermal conductivity of graphite, the heat is conducted to the circulating cooling water in the circulating cooling pipe 601, and the stainless steel pipe is cooled and dissipated for the first time. The temperature of the circulating cooling water rises due to the heating. When the heated circulating cooling water moves to the bent heat dissipation pipe 608, it is cooled for the first time through the bent heat dissipation pipe 608. The circulating cooling water after passing through the bent heat dissipation pipe 608 is respectively transported to the corresponding drain pipe 703 and discharged through the drain holes opened on the drain pipe 703. The circulating cooling water is discharged through the drain holes and contacts the inner wall of the arc-shaped top frame 711. The circulating cooling water flows along the arc-shaped top frame 711. The inner wall of the cooling water falls to the top of the water curtain guide plate 705 in the top connection frame 704 under the action of gravity. The circulating cooling water extends the water curtain guide plate 705 and moves downward to the bottom connection frame 704, and enters the return frame 709 through the drainage hole in the partition 708. In the process of the circulating cooling water falling along the water curtain guide plate 705, a part of the circulating cooling water will evaporate in the air and absorb the heat in the air, so that the surface temperature of the water curtain guide plate 705 is reduced. The released cold air will diffuse to the surroundings, reducing the temperature of the surrounding environment. The circulating cooling water evaporates and absorbs heat to cool the stainless steel pipe for the second time. The remaining circulating cooling water is cooled in the process of falling. The cooled circulating cooling water enters the return frame 709 and then flows back into the water tank 5 through the through frame 710.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
