Description

Technical Field

[0001] The utility model relates to the field of cooling equipment, in particular to a forming cooling device for processing thermal insulation pipes. Background Art

[0002] Insulated pipe, short for insulated pipe, is primarily used for conveying liquids, gases, and other media. Designed to ensure that the internal temperature of the working steel pipe meets or exceeds the surface temperature, it is widely used in central heating and cooling, hot oil transportation, and insulation projects in greenhouses, cold storage, coal mining, the petroleum industry, and the chemical industry. Insulated pipe consists of three parts: the pipe body, the insulation material, and the outer sheath. The pipe body transports the media, the insulation material reduces heat loss, and the outer sheath protects the entire piping system from environmental corrosion, ensuring long-term stable operation.

[0003] Regarding the above-mentioned related technologies, when the insulation pipe is produced, the steel pipe passes through the foaming extrusion device of the insulation material, and the insulation material is installed on the steel pipe. The insulation material still maintains a relatively high temperature after being shaped and extruded by the extrusion device, and the insulation pipe is not completely hardened. Water sprayed directly onto the insulation pipe can easily cause small dents and deformations on the surface of the insulation pipe, making the surface smoothness of the insulation pipe poor.

[0013] By adopting the above technical solution, the air source device transports the airflow into the expansion pipe through the air supply pipe, and the diverter block diverts the airflow in the expansion pipe, expanding the flow area of ​​the airflow, so that the airflow is fully colliding with the insulation pipe after being guided by the guide plate, and at the same time, water mist is blown onto the insulation pipe to cool the insulation pipe, which is beneficial to improving the cooling effect of the insulation pipe.

[0014] Optionally, a shaping mold compatible with the insulation pipe is fixed in the cooling box, and a plurality of supporting rollers are fixed on the end of the shaping mold away from the extrusion device.

[0032] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0033] The embodiment of the present application discloses a forming cooling device for processing thermal insulation pipes.

[0034] Reference Figure 1 and Figure 2 A forming and cooling device for processing an insulated pipe includes an extruder 1 for shaping the insulated pipe, which is connected to a cooling box 2. The extruder 1 extrude the formed insulated pipe into the cooling box 2, which is fixed with a shaping die 29 adapted for the insulated pipe. The shaping die 29 supports the freshly extruded insulated pipe, thereby reducing the probability of deformation of the insulated pipe.

[0035] Reference Figure 2 and Figure 3 A deflector 21 is fixedly mounted at the top end of the cooling box 2. This deflector 21 defines a water inlet 22, through which water flows into the deflector 21. The water inlet 22 is arranged tangentially along the deflector 21. A diverter plate 23 is fixedly mounted within the deflector 21, with a first downflow opening 25 defined at its center. The tangentially positioned water inlet 22 allows the water to spiral along the outer circumference of the diverter plate 23 toward the first downflow opening 25, ensuring sufficient contact between the water and the diverter plate 23.

[0036] Reference Figure 2 and Figure 3The upper end of the diverter plate 23 is fixed with an arc-shaped guide plate 7, through which the water is then diverted. The arc-shaped guide plate 7 can ensure the flow direction of the water. The diverter plate 23 is provided with a plurality of diverter holes 24. The water diverted by the arc-shaped guide plate 7 fully falls through the diverter holes 24, which can reduce the probability of water concentration and ensure the dispersion effect of the water flow.

[0037] Reference Figure 2 and Figure 4 The upper end of the cooling box 2 is rotatably connected to a driving rod 26. A driving component 4 for driving the driving rod 26 to rotate is provided on the outside of the cooling box 2. The driving component 4 includes a driving motor 41, a first pulley 42, a second pulley 43 and a conveyor belt 44. The driving motor 41 is fixedly connected to the cooling box 2, and the output shaft of the driving motor 41 is coaxially fixedly connected to the first pulley 42. The output shaft of the driving motor 41 drives the first pulley 42 to rotate.

[0038] Reference Figure 2 and Figure 4 The second pulley 43 is coaxially fixedly connected to the drive rod 26, and the first pulley 42 is connected to the second pulley 43 via a transmission belt. The second pulley 43 is driven by the transmission belt 44 to rotate with the second pulley 43, so that the second pulley 43 drives the drive rod 26 to rotate. The drive rod 26 is fixed with a plurality of first mist-making rods 11 along the circumference. The drive rod 26 drives the first mist-making rods 11 to rotate. The first mist-making rods 11 all correspond to the first downstream outlet 25; the water flowing through the first downstream outlet 25 collides with the high-speed rotating first mist-making rods 11, causing the first mist-making rods 11 to break up the water flow into mist.

[0039] Reference Figure 2 and Figure 4 When the first mist-generating rod 11 strikes the water flow, some of the water will collide with the first mist-generating rod 11 and splash onto the shroud 21. A second downflow opening 27 is defined in the center of the shroud 21. Several second mist-generating rods 12 are circumferentially fixed to the lower end of the drive rod 26, each corresponding to the second downflow opening 27. Water that directly falls onto the shroud 21 through the diverter holes 24 of the diverter plate 23, as well as water droplets that splash after colliding with the first mist-generating rod 11, all fall through the second downflow opening 27 onto the second mist-generating rods 12.

[0040] Reference Figure 2 and Figure 4 The driving rod 26 drives the second mist-making rod 12 to rotate at a high speed, so that the second mist-making rod 12 breaks up the water flow falling from the second downstream port 27 into water mist. The water mist falls onto the high-temperature insulation pipe under the action of gravity, cooling the insulation pipe, which is beneficial to reduce the probability of deformation of the insulation pipe and facilitates to ensure the quality of the insulation pipe.

[0041] Reference Figure 2 and Figure 4A water-blocking circular plate 8 is fixedly mounted at the lower end of the deflector 21, corresponding to the second mist-generating rod 12. When part of the water flows through the second downstream outlet 27 and collides with the second mist-generating rod 12, large water droplets that have not been fully dispersed are directly splashed. The water-blocking circular plate 8 blocks and guides the splashing large droplets, allowing the second mist-generating rod 12 to disperse the large droplets a second time. This reduces the probability of large droplets directly contacting the insulation pipe, thereby improving its protection.

[0042] Reference Figure 2 and Figure 5 An air supply assembly 5 is provided in the cooling box 2. The air supply assembly 5 includes an air supply pipe 52, an expansion pipe 53, a diversion block 54 and a guide plate 55. The air supply pipe 52 is fixedly connected to the cooling box 2 and is connected to an external air source device. The air source device conveys the airflow into the air supply pipe 52. The end of the air supply pipe 52 facing away from the air source device is fixedly connected to the expansion pipe 53. The airflow enters the diversion pipe through the air supply pipe 52.

[0043] Reference Figure 2 and Figure 5 A diverter block 54 is fixedly mounted within the expansion tube 53 and corresponds to the air supply tube 52. This diverter block 54 diverts the airflow within the expansion tube 53, expanding the airflow area. The upper end of the expansion tube 53 is fixedly connected to a guide plate 55. After being guided by the guide plate 55, the airflow fully impacts the insulation tube, while simultaneously spraying water mist onto the insulation tube, cooling it and enhancing its cooling effect.

[0044] Reference Figure 2 and Figure 4 A plurality of supporting rollers 18 are fixedly provided at one end of the shaping mold 29 away from the extrusion device 1. Both ends of the supporting rollers 18 along the length direction are rotatably connected to the cooling box 2. The supporting rollers 18 can be used to support the completely hardened insulation pipe, thereby achieving the effect of transporting the completely hardened insulation pipe.

[0045] Reference Figure 2 and Figure 4 The cooling box 2 is provided with a transmission assembly 6, which includes a first connecting rod 61, a second connecting rod 62, a transmission rack 63, a transmission gear 64, a transmission rod 65 and a bevel gear pair 66. One end of the first connecting rod 61 along the length direction is fixedly connected to the driving rod 26. When the driving rod 26 rotates, it can drive the first connecting rod 61 to rotate together. The end of the first connecting rod 61 away from the driving rod 26 is rotatably connected to the second connecting rod 62.

[0046] Reference Figure 2 and Figure 4The cooling box 2 is fixed with a limiting slide rail 28, and the transmission rack 63 is slidably connected to the limiting slide rail 28. The end of the second connecting rod 62 away from the first connecting rod 61 is rotatably connected to the transmission rack 63. The limiting slide rail 28 limits the transmission rack 63, so that the first connecting rod 61 drives the transmission rack 63 to slide back and forth through the second connecting rod 62.

[0047] Reference Figure 2 and Figure 4 A transmission rod 65 passes through the cooling box 2 and is rotatably connected thereto. A transmission gear 64 is coaxially and fixedly connected to the transmission rod 65 and meshes with the transmission rack 63. The transmission rack 63 drives the meshed transmission gear 64 to rotate back and forth, which in turn drives the transmission gear 64 to rotate the transmission rod 65 back and forth. A first cooling cylinder 13 and a second cooling cylinder 14 are rotatably connected within the cooling box 2. The first cooling cylinder 13 is coaxially and fixedly connected to the first gear 16.

[0048] Reference Figure 2 and Figure 4 The end of the transmission rod 65 facing away from the transmission gear 64 is fixedly connected to the input end of the bevel gear pair 66, and the output end of the bevel gear pair 66 is coaxially fixedly connected to the first gear 16. The reciprocating transmission rod 65 drives the first gear 16 to reciprocate through the bevel gear pair 66. The second cooling cylinder 14 is coaxially fixedly connected to the second gear 17, which meshes with the first gear 16. The first gear 16 drives the second gear 17 to reciprocate, thereby causing the first gear 16 and the second gear 17 to reciprocate, respectively, with the first cooling cylinder 13 and the second cooling cylinder 14.

[0049] Reference Figure 2 and Figure 4 The first cooling cylinder 13 and the second cooling cylinder 14 are both connected to an external water source, and a plurality of water spray holes 15 are provided at the lower ends of the first cooling cylinder 13 and the second cooling cylinder 14. The reciprocating first cooling cylinder 13 and the second cooling cylinder 14 spray water onto the insulation pipe through the water spray holes 15, further cooling the completely hardened insulation pipe and improving the cooling effect on the insulation pipe. A partition plate 19 is provided between the shaping mold 29 and the supporting roller 18. The partition plate 19 blocks the water sprayed from the first cooling cylinder 13, further reducing the probability of deformation of the insulation pipe caused by the impact of the water flow.

[0050] The implementation principle of a forming cooling device for processing an insulation pipe in an embodiment of the present application is as follows: the extrusion device 1 extrude the formed insulation pipe into the cooling box 2, and the water flows into the guide cover 21 through the water inlet 22. The tangentially arranged water inlet 22 can make the water flow move in a spiral shape along the outer circle of the diverter plate 23 toward the first downstream port 25, so that the water flow is fully in contact with the diverter plate 23. The water flow diverted by the arc-shaped guide plate 7 fully falls through the diverter hole 24, which can reduce the probability of water flow concentration and ensure the effect of breaking up the water flow. The drive assembly 4 drives the drive rod 26 to rotate, and the drive rod 26 drives the first mist-making rod 11 to rotate. The water flow falling through the first downstream port 25 conflicts with the high-speed rotating first mist-making rod 11, causing the first mist-making rod 11 to break up the water flow into water mist.

[0051] When the first mist-generating rod 11 strikes the water flow, part of the water flow collides with the first mist-generating rod 11 and splashes onto the deflector 21. The water flow that directly falls onto the deflector 21 through the diverter hole 24 of the diverter plate 23, as well as the water droplets that splash after colliding with the first mist-generating rod 11, all fall onto the second mist-generating rod 12 through the second downflow port 27. The drive rod 26 drives the second mist-generating rod 12 to rotate at high speed, causing it to break up the water flow falling from the second downflow port 27 into mist. Under the action of gravity, the mist falls onto the high-temperature insulation pipe, cooling it and reducing the probability of deformation of the insulation pipe, thereby ensuring its quality.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
