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.

[0003] During the production 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. During the production of stainless steel pipes, cooling is usually achieved by standing naturally and by using fans. The standing cooling time cycle is too long. The wind generated by the fan during the fan cooling process may cause uneven heat dissipation effects. 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 large amount of electricity to generate wind power, which will increase the energy consumption cost in the production process. In response to the above problems, the inventors proposed a cooling device for stainless steel pipe production to solve the above problems. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention sets a graphite heat dissipation component and a water circulation cooling component, so that the temperature of the stainless steel pipe itself is transferred 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 by the water circulation cooling component. By setting a water curtain cooling component, when the heated circulating cooling water passes through the water curtain cooling component, a part of the circulating cooling water evaporates under the action of the water curtain cooling component to absorb heat in the air, 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. 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 while the cooling and refluxing circulating cooling water is fully utilized, thereby improving cooling efficiency, reducing energy consumption required for cooling, and reducing cooling costs.

[0017] 2. The present invention provides a graphite heat dissipation component and a water circulation cooling component. The high temperature of the stainless steel pipe itself is conducted to the circulating cooling pipe through the graphite heat conduction frame, so that the circulating cooling water in the circulating cooling pipe is heated and 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 is cooled for the first time by heat conduction to the air. The above operation achieves the effect of cooling and dissipating heat for the stainless steel pipe, dissipates heat evenly and effectively for the stainless steel pipe, and avoids the influence of uniform heat dissipation of the stainless steel pipe on its own quality and strength during the heat dissipation process.

[0018] 3. The present invention sets 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, and the temperature of the water curtain guide plate will diffuse to the surroundings, reducing the temperature of the surrounding environment, thereby cooling the stainless steel pipe for the second time, and the remaining circulating cooling water is cooled in the process of falling along the water curtain guide plate, and the cooled circulating coolant returns to the water tank. Through the above operation, the stainless steel pipe is cooled for the second time and the heat dissipation is achieved while the heated circulating coolant is cooled and refluxed, thereby reducing the waste of water resources in the cooling process, reducing energy consumption and reducing production costs.

[0045] A pressure water pump 606 is fixedly installed on the top of the base 1 close to the water tank 5, and the water inlet end of the pressure water pump 606 is connected to the water tank 5, and the water inlet end of the pressure water pump 606 is connected to the water inlet pipe 605, and the other end of the water inlet pipe 605 is connected to the water inlet valve 603, and the water inlet valve 603 is fixedly connected to the corresponding circulating cooling pipe 601.

[0046] By adopting the above technical solution, the circulating cooling water in the water tank 5 is transported to the 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.

[0047] Two symmetrically distributed fixing rods 706 are fixedly installed between the two fixing frames 701 , and a plurality of evenly distributed fixing rings 707 are fixedly installed on the top of the fixing rods 706 , and the fixing rings 707 are fixedly connected to the drain pipe 703 .

[0048] By adopting the above technical solution, the fixing ring 707 can limit and fix the drain pipe 703.

[0049] A partition 708 is fixedly installed on the inner wall of the bottom connecting frame 704, and a reflux frame 709 used in conjunction with the connecting frame 704 is fixedly installed on the bottom end of the fixed frame 701. A through frame 710 is fixedly installed on the side of the reflux frame 709 close to the water tank 5, and the other end of the through frame 710 is fixedly connected to the water tank 5.

[0050] By adopting the above technical solution, the circulating cooling water in the reflux frame 709 is returned to the water tank 5 through the through frame 710 .

[0051] An arc-shaped top frame 711 used in conjunction with the drain pipe 703 is fixedly installed between the two fixing blocks 702 , and water retaining plates 712 are fixedly installed on both sides of the fixing frame 701 .

[0052] 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.

[0053] Two symmetrically distributed connecting frames 301 are fixedly installed between the No. 1 fixing frame 2 and the No. 2 fixing frame 3 . A fixing frame 302 is fixedly installed on the top of the connecting frame 301 , and the curved heat dissipation pipe 608 is fixedly connected to the fixing frame 302 .

[0054] 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 .

[0055] Working principle: First, connect the water injection valve 9 to the external water injection pipe and inject water into the water tank 5. After 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.

[0056] At this time, the pressure water pump 606 is controlled to be turned on. Under the action of the pressure water pump 606, 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. 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 discharged into the two curved heat dissipation pipes 608 through the double-way pipe 607.

[0057] 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 temperature of the air in 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 heat. When the heated circulating cooling water moves to the curved heat dissipation pipe 608, it is cooled for the first time through the curved heat dissipation pipe 608. The circulating cooling water after passing through the curved heat dissipation pipe 608 is respectively transported to the corresponding drain pipe 703 and discharged through the drain hole opened on the drain pipe 703. The circulating cooling water is discharged through the drain hole and contacts the inner wall of the arc-shaped top frame 711. The circulating cooling water flows along the arc-shaped top frame 71 The inner wall of the cooling water falls under the action of gravity to the top of the water curtain guide plate 705 in the top connection frame 704. 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 evaporates in the air and absorbs heat in the air, thereby reducing the surface temperature of the water curtain guide plate 705. The released cold air diffuses to the surrounding area, reducing the temperature of the surrounding environment. The circulating cooling water absorbs heat through evaporation, and the stainless steel pipe is cooled and dissipated for the second time. The remaining circulating cooling water is cooled during the falling process. 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 such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
