The accompanying heat treatment equipment can heat and cool the vessels to ensure optimal strength, corrosion resistance, and long-term reliability during production.

[0003] Traditional pressure vessel heat treatment systems typically consist of a heating furnace, a temperature control system, an airflow system, and a cooling device. The heating furnace provides the required high-temperature environment, the temperature control system ensures the temperature is maintained within a specified range, the airflow system guarantees a uniform heating process, and the cooling device assists in performing the necessary cooling treatment, thereby ensuring the quality and performance of the pressure vessel.

[0004] In traditional pressure vessel heat treatment systems, tower-type pressure vessels are prone to displacement due to their tall structure, which leads to uneven thermal expansion and contraction during heating or cooling, causing physical deformation. This is especially true during heat treatment, where uneven temperature distribution results in uneven stress on the vessel. Displacement in tower-type pressure vessels affects their design accuracy, reduces sealing and pressure-bearing capacity, and can even cause damage or failure, increasing maintenance and replacement costs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The fixing assembly includes multiple fixing platforms 6, which are set on the side wall of the connecting plate 3. Multiple arc-shaped sliding grooves 5 are opened inside the connecting plate 3. Each fixing platform 6 has a side platform 7 fixedly connected to its side wall. A sliding shaft 8 is slidably connected inside the side platform 7. A clamping platform 9 is fixedly connected to one end of the sliding shaft 8. A push shaft 10 is fixedly connected to the side wall of the clamping platform 9. The push shaft 10 is slidably connected inside the arc-shaped sliding groove 5. A cooling assembly is set on the side wall of the heating furnace 1.

[0020] Reference Figure 4 and Figure 5The cooling assembly includes a cooling box 11, which is disposed on the side wall of the heating furnace 1. Multiple connecting pipes 13 are fixedly connected to the side wall of the cooling box 11, and a fixed pipe 14 is fixedly connected to the side wall of each connecting pipe 13. Multiple cooling pipes 12 are disposed inside the heating furnace 1. A sleeve 15 is fixedly connected to one end of each cooling pipe 12. A slot 16 is opened inside each sleeve 15. Multiple rotating shafts 17 are rotatably connected to the outer wall of the fixed pipe 14. A rotating plate 18 is fixedly connected to the outer wall of each rotating shaft 17. A clamping plate 19 is fixedly connected to the side wall of the rotating plate 18. The clamping plate 19 is slidably connected inside the slot 16. A spring 20 is disposed on the side wall of the rotating plate 18. One end of the spring 20 is fixedly connected to the side wall of the rotating plate 18, and the other end of the spring 20 is fixedly connected to the outer wall of the fixed pipe 14.

[0021] Working principle: First, when the motor 4 drives the connecting plate 3 to rotate, the push shaft 10 slides along the arc-shaped groove 5 of the connecting plate 3, driving the clamping platform 9 and the sliding shaft 8 to slide in the side platform 7. Multiple clamping platforms 9 move towards the center synchronously with the push shaft 10, clamping the large tower-type pressure vessel. The fixed platform 6 and the side platform 7 ensure the stable movement of the sliding shaft 8. The clamping force is evenly distributed by the guide of the arc-shaped groove 5, avoiding the displacement of the vessel due to thermal expansion and contraction during heat treatment, and ensuring the processing accuracy. The coolant in the cooling box 11 enters the fixed pipe 14 through the connecting pipe 13, pushing the rotating plate 18 to rotate around the rotating shaft 17, so that the clamping plate 19 is inserted into the slot 16 of the sleeve 15 of the cooling pipe 12. The spring 20 returns to its original position and tightens the rotating plate 18, ensuring a sealed connection between the fixed pipe 14 and the sleeve 15. The coolant circulates in the heating furnace 1 through the cooling pipe 12. Multiple cooling pipes 12 are evenly distributed to achieve rapid overall cooling of the vessel. The cooperation between the clamping plate 19 and the slot 16 facilitates the disassembly and maintenance of the cooling components, improving cooling efficiency and stability.
