Description

Technical Field

[0001] This application relates to the field of seamless steel pipe processing equipment, and in particular to a well-type aerosol cooling device for large-diameter seamless steel pipes. Background Technology

[0002] Seamless steel pipes require normalizing treatment to refine grains, eliminate internal stress, and homogenize the microstructure. After normalizing heat treatment, seamless steel pipes need to be cooled to optimize their microstructure and mechanical properties.

[0003] Existing cooling methods typically involve directly spraying the normalized steel pipe during transportation to lower its temperature. However, during the spraying process, different areas of the steel pipe experience varying cooling effects, resulting in poor uniformity of cooling and failing to meet product performance requirements. Utility Model Content

[0007] By adopting the above technical solution, the steel pipe is placed in the placement slot of the well frame. At this time, the water supply component supplies water to the water spraying mechanism, and the rotating mechanism drives the steel pipe to rotate. At this time, the water spraying mechanism sprays water onto the surface of the steel pipe, and the steel pipe is cooled evenly and the cooling effect is good.

[0008] Optionally, the water spraying mechanism includes a water spray pipe and nozzles. The water spray pipe is mounted on the well frame and is distributed parallel to the steel pipe. Several water spray pipes are arranged in a ring and are evenly spaced on the well frame. The water spray pipe is connected to the water supply assembly. The nozzles are located on the side of the water spray pipe facing the steel pipe. Several nozzles are provided and are evenly spaced along the length of the water spray pipe.

[0034] This application discloses a large-diameter seamless steel pipe two-well type aerosol cooling device, referring to... Figure 1 and Figure 2 The system includes a vertically mounted well frame 1, mainly constructed of welded I-beams and channel steel. The well frame 1 forms a placement slot 11 in the middle for placing steel pipes 2. An operating platform 12 is horizontally mounted on top of the well frame 1. The steel pipes 2 are vertically suspended from the placement slot 11 by a hoisting frame 3, which is placed on the operating platform 12. A rotating mechanism 4 is mounted on the operating platform 12. A water spray assembly is installed on the well frame 1, comprising four sets of water spray mechanisms 5, evenly spaced along the circumference of the well frame 1. A water supply assembly 6 is located on one side of the well frame 1 to supply water to the water spray mechanisms 5. When the steel pipes 2 are placed in the placement slot 11 of the well frame 1, the water supply assembly 6 supplies water to the water spray mechanisms 5. The rotating mechanism 4 drives the steel pipes 2 to rotate, and the water spray mechanisms 5 spray water onto the surface of the steel pipes 2, resulting in uniform and effective cooling of the steel pipes 2.

[0035] Reference Figure 2 and Figure 3 The rotating mechanism 4 includes a geared motor 41 and a heat-insulating ring plate 42. A slewing bearing 13 is rotatably mounted on the operating platform 12. The slewing bearing 13 is horizontally positioned and coaxially distributed with the placement groove 11.

A groove 421 is provided on the heat-insulating ring plate 42. The lifting frame 3 is placed on one side of the groove 421 on the heat-insulating ring plate 42. The geared motor 41 is mounted on the operating platform 12. A gear 43 is coaxially connected to the output shaft of the geared motor 41. A gear ring 141 is provided on the outer circumference of the rotating ring 14 of the slewing bearing 13. The gear 43 meshes with one side of the gear ring 141 of the slewing bearing 13. The geared motor 41 drives the gear 43 to rotate, and the gear 43 drives the rotating ring 14 of the slewing bearing 13 to rotate via the gear ring 141, thereby driving the lifting frame 3 and then driving the steel pipe 2 to rotate. The driving operation is convenient, and the variable frequency speed regulation of the geared motor 41 makes it highly efficient and energy-saving.

[0036] Reference Figure 1 and Figure 2The water spraying mechanism 5 includes water spray pipes 51 and nozzles 52. Four water spray pipes 51 are vertically mounted on the well-type frame 1, forming a ring and evenly spaced apart. The water spray pipes 51 are connected to the water supply assembly 6. Several nozzles 52 are located on the side of the water spray pipes 51 facing the steel pipe 2, and are evenly spaced along the length of the water spray pipes 51. The water supply assembly 6 supplies water to the water spray pipes 51, which is then sprayed through the nozzles 52 onto the surface of the steel pipe 2 for cooling. The circumferential water spray pipes 51 spray water onto the steel pipe 2 for uniform cooling.

[0037] Reference Figure 1 and Figure 2 The nozzles 52 on adjacent water spray pipes 51 are staggered vertically. An annular support pipe 15 is installed on the well-type frame 1 to support the nozzles 52, ensuring that the water sprayed from the nozzles 52 covers the surface of the steel pipe 2 when the steel pipe 2 rotates, further ensuring uniform cooling. The nozzles 52 are spray nozzles with a 75-degree wide-angle circular spray pattern. These spray nozzles can break the liquid into micron-sized droplets, improving contact efficiency and resulting in better coverage uniformity.

The drainage pump 101 is connected to the water tank tray 16 through the drainage pipe 102. The drainage pump 101 is connected to the cooling tower 19 through the water pipe. A pipe filter 103 is installed on the water pipe. The drainage pump 101 delivers water to the cooling tower 19 for circulation and cooling, and then stores it in the water tank 18. The drainage pump 101 is controlled by a liquid level sensor and automatically starts and stops according to the water level in the collection tank.

[0041] The overall equipment is started and stopped through the control system, which mainly includes a field control cabinet, frequency converter, contactor, relay, operation buttons, etc., to control the rotation of steel pipe 2, the automatic start and stop of booster pump 61 and drainage pump 101, and the automatic water and air supply of nozzles.

[0043] In actual use, multiple cooling devices are set up and activated simultaneously to cool the steel pipe 2.

[0044] The implementation principle of a large-diameter seamless steel pipe well-type aerosol cooling device in this application embodiment is as follows: the hoisting frame 3 drives the steel pipe 2 to the placement slot 11 of the well-type frame 1, the reduction motor 41 drives the slewing bearing 13 to drive the hoisting frame 3 to rotate, and then drives the steel pipe 2 to rotate. At this time, the booster pump 61 supplies water to the water spray pipe 51, which is sprayed out through the nozzle 52 to the surface of the steel pipe 2 for cooling.
