Description

A high-temperature gas cooling device for pipe fittings Technical Field

[0001] This utility model relates to the field of pipe fitting processing, and in particular to a high-temperature gas cooling device for pipe fittings. Background Technology

[0002] High-temperature treatment is a common process step in pipe fitting manufacturing, such as welding and heat treatment. However, pipe fittings after high-temperature treatment need to be rapidly cooled to fix their shape, increase their hardness and strength, and reduce deformation and oxidation. Traditional cooling methods, such as water cooling or natural cooling, suffer from uneven cooling, low efficiency, and susceptibility to corrosion. Therefore, developing an efficient, uniform, and safe high-temperature air cooling device for pipe fittings is of paramount importance. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a device that has the advantages of achieving efficient and uniform cooling of pipe fittings, while avoiding corrosion and oxidation problems, and improving the processing quality and production efficiency of pipe fittings.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A high-temperature gas cooling device for pipe fittings includes a base, a cooling box fixedly connected to the top of the base, symmetrical feeding holes at both ends of the cooling box, and a conveying mechanism located inside the cooling box between the feeding holes. The conveying mechanism includes a first conveying roller and a second conveying roller arranged vertically and parallel to each other inside the cooling box, forming a conveying channel between the first and second conveying rollers. One end of the first conveying roller extends to the outside of the cooling box, and a drive motor is connected to the extended end of the first conveying roller via a coupling. Both the first and second conveying rollers have conveying wheels on their surfaces, which are symmetrically arranged. A bracket is fixedly connected to one side of the conveying channel adjacent to the cooling box. An air cooling device is located at the center of the top of the bracket. The air cooling device includes a cooling ring fixedly connected to the center of the top of the bracket. An annular nozzle is located inside the cooling ring and connected to a high-pressure air pump. The high-pressure air pump is located on the outer wall of the cooling box. Multiple inclined nozzles are evenly distributed on the inner circumference of the annular nozzle, and the axes of the multiple inclined nozzles form a 45° angle with the radial direction of the annular nozzle.

[0006] By adopting the above technical solution, during operation, the operator puts the pipe into the cooling box through the feeding hole on the left side of the cooling box. At this time, the pipe first passes through the cooling ring on the support and reaches the conveyor wheel between the first and second conveyor rollers. Then, the operator turns on the drive motor to drive the first conveyor roller to rotate. Through the cooperation of the second conveyor roller and the conveyor wheel, the pipe is conveyed to the feeding hole on the right side of the cooling box. During the conveying process, the operator turns on the high-pressure air pump to spray cooling gas through the annular nozzle. The rotating airflow generated by the inclined nozzle wraps around the surface of the pipe, achieving the cooling effect on the surface of the pipe, avoiding corrosion and oxidation problems, and greatly improving the cooling efficiency.

[0007] Further configuration: The feeding hole, conveying channel, and cooling ring are located at the same horizontal position.

[0008] By adopting the above technical solution, the linear movement of the pipes is ensured, collisions with the cooling ring are avoided, and the system reliability is improved.

[0009] Further feature: The inner wall of the cooling box is equipped with a heat insulation plate.

[0010] By adopting the above technical solution and installing heat insulation panels, heat loss can be reduced and energy utilization efficiency can be improved.

[0011] Further configuration: Both the first conveying roller and the second conveying roller are hollow structures, and each has a cooling water channel inside. The cooling water channel is connected to an external coolant circulation system through a rotary joint.

[0012] By adopting the above technical solution, when the pipe passes between the first conveying roller and the second conveying roller, the surface of the first conveying roller, the second conveying roller, and the conveying wheel will generate a certain temperature. Through the circulation of coolant and rotary joint connected to the external coolant circulation system, the heat on the surface of the roller can be removed, thereby improving the service life of the first conveying roller and the second conveying roller.

[0013] Further feature: The top of the cooling box is hinged with a box cover, and the box cover has a transparent observation window.

[0014] By adopting the above technical solution, the combination of the box cover and the transparent observation window facilitates real-time observation of the internal working conditions while ensuring operational safety.

[0015] Further features: The bottom of the cooling box is equipped with support bases on all four sides, and the bottom of each support base is equipped with shock-absorbing pads.

[0016] By adopting the above technical solution, the combination of the support base and the shock-absorbing pad can reduce the vibration of the equipment and improve the stability of the equipment operation.

[0017] Further feature: Anti-slip pads are fixedly connected to the surface of each conveyor wheel.

[0018] By adopting the above technical solution, the anti-slip pads can be installed between the conveyor wheels to improve the gripping force of the pipe fittings and prevent slippage.

[0019] In summary, this utility model has the following beneficial effects:

[0020] This utility model has a conveying mechanism. During operation, the operator puts the pipe into the cooling box through the feeding hole on the left side of the cooling box. At this time, the pipe first passes through the cooling ring on the bracket and reaches the conveying wheel between the first conveying roller and the second conveying roller. Then the operator turns on the drive motor to drive the first conveying roller to rotate. Through the cooperation of the second conveying roller and the conveying wheel, the pipe is accurately conveyed to the feeding hole on the right side of the cooling box.

[0021] This utility model has a cooling device. During the transportation of the pipe fittings, the operator turns on the high-pressure air pump to spray cooling gas through the annular nozzle. The rotating airflow generated by the inclined nozzle wraps around the surface of the pipe fittings, thereby achieving the cooling effect on the surface of the pipe fittings, avoiding corrosion and oxidation problems, and greatly improving the cooling efficiency.
