Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe cooling, and particularly relates to a spiral water-proof steel pipe cooling device. Background Art

[0002] In steel pipe production enterprises, the heat treatment process of steel pipes includes: steel pipe heating - quenching - tempering - straightening - cooling on the cooling bed - flaw detection - inspection - spraying marks - packing. Flaw detection is to detect the quality of the steel pipe itself during the production process, including the thickness of the steel pipe itself, the surface quality of the inner side, etc. The equipment for detecting steel pipe quality problems includes water ultrasonic flaw detectors, electromagnetic flaw detectors, magnetic flux leakage flaw detectors, magnetic particle flaw detectors, etc. No matter which detection equipment is used to detect the steel pipe, the temperature of the steel pipe itself has a certain impact on the detection elements of the detection equipment. Therefore, the steel pipe needs to be cooled before detection.

[0003] In the prior art, the nozzles of the commonly used steel pipe cooling equipment are arranged in a ring shape. During the cooling process of the steel pipe by the ring-shaped nozzles, the phenomenon of cooling water counterflow is likely to occur (counterflow means that the water spraying directions of two nozzles form an included angle of 180°, and the two nozzles spray water towards the steel pipe at the same time, and the water sprayed by the nozzles undergoes a counterflow phenomenon). Since the head and tail ends of the steel pipe are open, it is easy to cause cooling water to enter the head and tail ends of the steel pipe. The cooling water entering the steel pipe interior affects the cooling effect of the steel pipe, reduces the quality of the steel pipe, and is not conducive to flaw detection, with poor practicability.

[0036] Please refer to Figures 1 to 4 , and now a spiral water - proof steel pipe cooling device provided by the present utility model will be described. The spiral water - proof steel pipe cooling device includes a supporting and conveying assembly 10, a water supply unit 20, and a cooling water spraying structure 30. The supporting and conveying assembly 10 is used to support the steel pipe 50 and drive the steel pipe 50 to move. The water supply unit 20 has a passage through which the steel pipe 50 passes and is used to provide cooling water for cooling the steel pipe. The cooling water spraying structure 30 is arranged in the passage, communicated with the water supply unit 20, and spirally surrounds the outer periphery of the steel pipe 50 and is used to spray the cooling water onto the steel pipe 50.

[0037] In this embodiment, the supporting and conveying assembly 10 is used to support the steel pipe 50 and drive the steel pipe 50 to move. The water supply unit 20 has a channel for the steel pipe 50 to pass through and is used to provide cooling water for cooling the steel pipe. Thus, the supporting and conveying assembly 10 drives the steel pipe 50 to move through the channel of the water supply unit 20. During the process of passing through the channel, the water supply unit 20 is used to provide cooling water for cooling the steel pipe. A cooling water spraying structure 30 is arranged in the channel. The cooling water spraying structure 30 is communicated with the water supply unit 20, and the cooling water spraying structure 30 is spirally wound around the outer periphery of the steel pipe 50. Thus, cooling water is sprayed onto the steel pipe 50 through the cooling water spraying structure 30 to realize the cooling of the steel pipe 50.

[0038] A spiral water-proof steel pipe cooling device provided by an embodiment of the present utility model, compared with the prior art, supports the steel pipe 50 through the supporting and conveying assembly 10 and drives the steel pipe 50 to move. The water supply unit 20 has a channel for the steel pipe 50 to pass through. Thus, the supporting and conveying assembly 10 drives the steel pipe 50 to move through the channel of the water supply unit 20. The water supply unit 20 provides cooling water for cooling the steel pipe. A cooling water spraying structure 30 is arranged in the channel of the water supply unit 20. The cooling water spraying structure 30 is communicated with the water supply unit 20. Thus, cooling water can be sprayed onto the steel pipe 50 through the cooling water spraying structure 30. At the same time, the cooling water spraying structure 30 is spirally wound around the outer periphery of the steel pipe 50. Thus, cooling water can be evenly sprayed onto the steel pipe 50, and the cooling water can be prevented from flushing against each other, preventing the cooling water from entering the steel pipe 50, ensuring the cooling effect of the steel pipe 50 and the quality of the steel pipe 50, ensuring the accuracy of the exploration result, and avoiding damage to the detection equipment, saving costs, and having good practicability.

[0039] In some embodiments, please refer to Figure 1 , and set the moving direction of the steel pipe 50 as the first direction. The supporting and conveying assembly 10 includes a supporting seat 11, a conveying roller 12, and a driver (not shown in the figure). The number of the supporting seats 11 is multiple, and the supporting seats 11 are arranged at intervals along the first direction. The number of the conveying rollers 12 is multiple, and each conveying roller 12 is correspondingly arranged with each supporting seat 11. Each conveying roller 12 is rotatably arranged on the corresponding supporting seat 11. The driver has a power output end, and the power output end is connected to one of the conveying rollers 12 for driving the corresponding conveying roller 12 to rotate. In this embodiment, the steel pipe 50 is driven to move by the conveying roller 12 so as to facilitate the steel pipe 50 to pass through the channel of the water supply unit 20.

[0040] In some embodiments, please refer to Figures 1 to 3, the water supply unit 20 includes a circulation pool, a cooling box body 21, and a return pipe 22. The circulation pool (not shown in the figure) is used to provide cooling water for the cooling steel pipe 50. The cooling box body 21 is communicated with the circulation pool through a water inlet pipe 23 and has a passage for the steel pipe 50 to pass through. One end of the return pipe 22 is communicated with the cooling box body 21, and the other end is communicated with the circulation pool, which is used to divert the water in the cooling box body 21 into the circulation pool. In this embodiment, the cooling box body 21 is communicated with the circulation pool through the water inlet pipe 23, and the water in the water inlet pipe 23 is introduced into the cooling spray structure 30 to be sprayed onto the steel pipe 50 through the cooling spray structure 30. A return pipe 22 is also arranged between the cooling box body 21 and the circulation pool, and the return pipe 22 diverts the water after cooling the steel pipe 50 in the cooling box body 21 into the circulation pool. Specifically, there is a structure for cooling water in the circulation pool, and this structure can adopt the existing technology and will not be elaborated here. Then, the return pipe 22 diverts the water after cooling the steel pipe 50 in the cooling box body 21 into the circulation pool, and the cooling water is recycled, making full use of resources and saving costs.

[0041] Preferably, the cooling box body 21 is arranged on the mounting frame 25, and the cooling box body 21 is supported by the mounting frame 25.

[0042] In some embodiments, please refer to Figure 2 and Figure 4 , the spiral anti-water-inlet steel pipe cooling device provided by the embodiment of the present utility model further includes an auxiliary support structure 40 arranged in the cooling box body 21. The auxiliary support structure 40 includes a base 41 and a supporting roller 42. The base 41 is arranged in the cooling box body 21, and the supporting roller 42 is rotatably arranged on the base 41 and is used to support the steel pipe 50. Specifically, the cooling box body 21 is located between two of the support seats 11. In this embodiment, when the length of the steel pipe 50 is short, the steel pipe 50 can be supported and conveyed by the supporting roller 42 and the conveying roller 12. When the length of the steel pipe 50 is long, the steel pipe 50 can be directly supported and conveyed by the conveying roller 12. When the steel pipe 50 passes through the passage of the cooling box body 21, the supporting roller 42 can play an auxiliary supporting role for the steel pipe 50, making the supporting and conveying more stable, avoiding the steel pipe 50 from falling, and having good practicability.

[0043] In some embodiments, please refer to Figure 2, the cooling water spraying structure 30 includes a diversion pipe 31 and nozzles 32. The diversion pipe 31 is spirally arranged in the channel of the cooling box body 21, and the diversion pipe 31 is communicated with the water inlet pipe 23. The number of the nozzles 32 is multiple, and each nozzle 32 is evenly distributed on the diversion pipe 31. In this embodiment, the diversion pipe 31 is spirally arranged in the channel of the cooling box body 21, and the diversion pipe 31 is communicated with the water inlet pipe 23. Thus, the cooling water in the water inlet pipe 23 enters the diversion pipe 31. The multiple nozzles 32 are evenly distributed on the diversion pipe 31. Further, the cooling water in the diversion pipe 31 is sprayed onto the steel pipe 50 through each nozzle 32 to cool the steel pipe 50. The water spraying paths of all the nozzles 32 are perpendicular to the traveling route of the steel pipe, and the diversion pipe 31 is spiral. The water spraying paths of all the nozzles 32 are not in the same plane. Therefore, the opposite nozzles 32 will not collide with each other. Specifically, evenly distributed round holes are machined in the inner ring of the diversion pipe 31, and a nozzle joint 32 is welded and fixed at each round hole. The nozzle joint 32 is made of stainless steel to prevent rust and water leakage after being used for a period of time. One end of the nozzle joint 32 has internal threads, and the nozzle 32 is threadedly connected with the nozzle joint 32.

[0044] In some embodiments, please refer to Figure 2 , the horizontal direction perpendicular to the first direction is set as the second direction. The cooling water spraying structure 30 further includes fixing plates. The number of the fixing plates is multiple, and each fixing plate is evenly distributed on both sides of the diversion pipe 31 along the second direction. Each fixing plate is used to fix the diversion pipe 31 in the channel of the cooling box body 21. In this embodiment, fixing plates are respectively arranged on both sides of the diversion pipe 31, and the diversion pipe 31 is fixed in the channel of the cooling box body 21 through each fixing plate, ensuring the stability of the installation of the diversion pipe 31 and preventing the diversion pipe 31 from shaking during the water spraying process.

[0045] In some embodiments, please refer to Figure 3 , a ball valve 24 is arranged on the water inlet pipe 23, and the ball valve 24 is used to adjust the opening degree of the water inlet pipe 23. In this embodiment, during the process of cooling the steel pipe 50, the opening degree of the water inlet pipe 23 can be adjusted through the ball valve 24 according to the temperature condition of the steel pipe 50. When the temperature of the steel pipe 50 is relatively high, the opening degree of the water inlet pipe 23 is increased; when the temperature of the steel pipe 50 is relatively low, the opening degree of the water inlet pipe 23 is decreased, and the operation is convenient.
