Description

Technical Field

[0001] The present invention mainly relates to the field of metal surface treatment, and in particular to a spraying and drying device for metal structural parts. Background Art

[0002] Spray coating (such as painting and powder coating) is a widely used, critical process in the manufacturing and corrosion protection of metal structures. After spraying, the coating needs to be cured or dried by heating to achieve the desired physical properties (such as hardness, adhesion, and wear resistance) and chemical properties (such as corrosion resistance). The main methods for drying metal structures include large drying rooms, open heating equipment, and small tabletop drying ovens.

[0003] During the operation of the specific embodiment, the inventors found the following defects: Among them, large drying rooms have larger heating space, and less heat acts on the surface of metal structural parts, which will cause greater energy loss. However, small desktop drying boxes require manual labor to frequently take out metal structural parts.
