Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment, in particular to a rapid cooling device. Background Art

[0002] Heat treatment refers to a metal hot processing technology that uses heating, insulation and cooling to obtain the expected structure and performance of the material in the solid state. After heating, the workpiece needs to be cooled. The cooling method of the workpiece plays a very important role in improving the strength of the workpiece. The current method is to use a blower to remove the heat from the surface of the workpiece. Since the blower blows air in one direction, the workpiece cannot be cooled evenly. In this way, the hot air on the other side of the blocked workpiece is not easy to flow, which reduces the efficiency of the workpiece cold treatment and the quality of the product. In addition, although the traditional honeycomb cold air outlet can increase the contact area between the cold air and the workpiece surface, the corresponding air flow rate will also be reduced, which leads to poor cooling effect in the middle position. Therefore, a rapid cooling device is needed. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a rapid cooling device for solving the problem of uniformity in cooling a workpiece after heat treatment in the prior art.

[0004] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0016] In one embodiment of the present invention, a plurality of cooling fans are provided on the long side ends of the air inlet compartments along the length direction of the conveyor frame, and air inlet holes are provided in the circumferential direction of the air inlet compartments.

[0017] To implement the above technical solution, the setting of the air inlet holes can improve the smoothness of the gas in the cooling cabin. When the air intake at the cooling source end cannot meet the output at the multiple groups of cooling fans, the air inlet holes can assist in providing the air intake, thereby ensuring the smoothness of the airflow at the cooling fans.

The air guide platform is in the shape of a cone, and the long side end of the air guide platform is connected to the cabinet. Multiple groups of exhaust fans are provided at the bottom of the air guide platform.

[0019] By implementing the above technical solution, the gas exhausted by multiple exhaust fans can be discharged to the outside in a timely manner through the cone-shaped air guide platform, thereby improving the gas flow at the exhaust fans.
