Description

Technical Field

[0001] This utility model relates to the field of galvanized steel pipe technology, specifically to a galvanized steel pipe forming and cooling device. Background Technology

[0002] Hot-dip galvanized steel pipes are processed at relatively high temperatures, and the temperature does not drop immediately after processing. This greatly prolongs the processing time and increases costs.

[0003] Utility model patent CN219913568U discloses a galvanized steel pipe forming cooling device, which solves the problems of low heat dissipation efficiency and dead zones in existing heat dissipation cooling devices, which cannot rapidly cool the galvanized steel pipe from all directions. The device uses two annular cooling rings with nozzles evenly distributed inside the rings. The two cooling rings can spray cooling water onto the galvanized steel pipe from all directions. An electric push rod indirectly controls the reciprocating movement of the two cooling rings along the galvanized steel pipe, allowing for rapid and thorough cooling without dead zones. While the structure is simple, in practical use, it only relies on spraying cooling water, resulting in a single heat dissipation method and a slow heat dissipation rate. Utility Model Content

[0021] refer to Figure 1 and Figure 4 The drive assembly 17 includes a drive box 18 fixedly connected to the front and rear sides of the top of the base plate 1. A slider 21 is slidably connected inside the drive box 18. The top of the slider 21 is fixedly connected to the bottom of the support frame 10. A first threaded rod 19 is rotatably connected inside the drive box 18. The right side of the first threaded rod 19 extends to the right side of the drive box 18 and is fixedly connected to a synchronous pulley 20. The two synchronous pulleys 20 are connected by a synchronous belt drive. The first threaded rod 19 is threadedly connected to the slider 21.

[0022] As a technical optimization of this utility model, by setting the drive component 17, the operator can start the motor 22 to reciprocate and rotate, thereby driving the first threaded rod 19 to reciprocate and rotate. Then, through the synchronous pulley 20 and the synchronous belt, the two first threaded rods 19 at the front and rear can reciprocate and rotate synchronously, thereby driving the two sliders 21 at the front and rear to move back and forth, and thus driving the support frame 10 to move back and forth.

[0023] refer to Figure 1 A water baffle 24 is fixedly connected to the surface of the base plate 1. The water baffle 24 is in contact with the drive box 18. The water baffle 24 is rotatably connected to the first threaded rod 19. A motor 22 is fixedly connected to the left side of the water baffle 24. The output end of the motor 22 is fixedly connected to the first threaded rod 19. A drain valve is connected to the left side of the water baffle 24.

[0024] As a technical optimization of this utility model, by setting up the water baffle 24 and the drain valve, the water baffle 24 can block and limit the water falling to the top of the bottom plate 1, and the water at the top of the bottom plate 1 is discharged from the drain valve. The inner wall of the drive box 18 is provided with a drain port. When some water splashes into the drive box 18, it can be discharged to the top of the bottom plate 1 through the drain port.

[0025] refer to Figure 1 and Figure 4 The right side of the water shield 24 is fixedly connected to the protective cover 23 by bolts, and the synchronous pulley 20 and the synchronous belt are both located inside the protective cover 23.

[0026] As a technical optimization of this utility model, the protective cover 23 can prevent the operator from being injured by accidentally touching the timing belt or timing pulley 20.

[0028] As a technical optimization of this utility model, by setting the bearing, the friction between the drive box 18 and the first threaded rod 19 can be reduced, thereby facilitating the rotation of the first threaded rod 19.

[0029] refer to Figure 1 and Figure 4 A cylinder 25 is fixedly connected to all four sides of the bottom of the base plate 1. A second threaded rod 26 is threadedly connected inside the cylinder 25. A support pad 27 is fixedly connected to the bottom of the second threaded rod 26.

[0030] As a technical optimization of this utility model, by setting up the cylinder 25, the second threaded rod 26 and the support pad 27, the operator can rotate the support pad 27, thereby moving the support pad 27 up or down, and thus adjusting the height or level of the base plate 1.

[0031] The working principle and usage process of this utility model are as follows: During use, the operator clamps the galvanized steel pipe body 6, which is at a high temperature, inside the limiting cylinder 4. The galvanized steel pipe body 6 is stably supported by the support bracket 2, the limiting ring 3, and the limiting cylinder 4. Some of the heat of the galvanized steel pipe body 6 is transferred to the surface of the limiting cylinder 4. The operator connects the water inlet 8 at the left end of the spiral heat dissipation pipe 7 to the external water pipe through a flange, so that external cold water flows into the spiral heat dissipation pipe 7, thereby absorbing the heat on the surface of the limiting cylinder 4, and thus indirectly dissipating the heat of the galvanized steel pipe body 6 in the first stage. The water outlet 9 at the right end of the spiral heat dissipation pipe 7 is connected to the external collection water tank through a pipe, thereby recovering the water flowing through the spiral heat dissipation pipe 7. The operator can perform heat recovery treatment on the hot water in the collection water tank.

[0032] The air inlet pipe 13 at the top of the first cooling ring 11 is connected to the external air pump via a hose, and the water inlet pipe 16 at the top of the second cooling ring 14 is connected to the external water pump via a hose. The operator can start the air pump and water pump to discharge airflow through the air outlet pipe 12, thereby accelerating the airflow rate on the surface of the limiting cylinder 4 and part of the galvanized steel pipe body 6, thus performing the second stage of heat dissipation on the galvanized steel pipe body 6. The nozzle 15 sprays water, thereby spraying water on the surface of the limiting cylinder 4 and part of the galvanized steel pipe body 6, thereby utilizing the heat absorption of water vaporization, thus performing the third stage of heat dissipation on the galvanized steel pipe body 6. The operator can adjust the drive component 17 to drive the support frame 10, the first cooling ring 11 and the second cooling ring 14 to move back and forth left and right, thereby uniformly dissipating heat from the limiting cylinder 4 and the galvanized steel pipe body 6, thereby improving the heat dissipation effect.

[0033] The aforementioned water pump and air pump are common and mature technologies available on the market, and will not be described in detail here. The aforementioned second cooling ring 14, nozzle 15 and galvanized steel pipe body 6 are similar in principle to the cooling ring, nozzle and galvanized steel pipe mentioned in the utility model patent of CN219913568U, a galvanized steel pipe forming cooling device, and achieve the same effect, and will not be described in detail here. The first cooling ring 11 and air outlet pipe 12 in this device are similar in principle to the second cooling ring 14 and nozzle 15 in this device, and will not be described in detail here.
