[0002] Aluminum alloy profiles are the most widely used type of non-ferrous metal structural materials in industry, and have been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, construction, decoration and chemical industries. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy welded structural parts has increased day by day. With the increase in the diversity of demand for aluminum profiles, the surface of some aluminum profiles often needs to be sprayed to improve the surface performance and aesthetics of the aluminum profiles. However, after the spraying process, the sprayed profiles need to be dried so that the sprayed powder is solidified on the profile surface. The existing drying devices are all dried through ovens, but because the entire oven is only equipped with a set of hot air blower structures, the temperature at both ends of the oven is not uniform, which affects the drying effect. In the process of circulating drying, the detached sandblasting particles will be sucked into the fan and will enter the heater at the same time. When heated by the heater, there are certain safety hazards. Summary of the invention
