Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying and drying, in particular to an aluminum single plate paint spraying and drying device. Background Art

[0002] Aluminum veneer refers to a building decoration material that is processed by chroming and other treatments and then processed using fluorocarbon spraying technology. Aluminum veneer entered the Chinese building decoration field in the early 1990s. There are two types of aluminum veneers in the world: fluorocarbon sprayed aluminum veneer and roller coated aluminum veneer. After the aluminum veneer is painted, in order to ensure the quality of the paint, the paint on the surface of the aluminum veneer needs to be dried through a drying device.

[0003] For example, the Chinese patent "CN214975453U A drying device for finished aluminum panels after painting is completed" with a publication date of 2021.12.03, is used to dry the aluminum panels after painting on the mesh conveyor belt through a drying mechanism. Since the first mesh conveyor belt and the second mesh conveyor belt are metal mesh type, and each set of air outlet ducts are distributed above and below the first mesh conveyor belt and the second mesh conveyor belt, the aluminum panels passing through the first mesh conveyor belt and the second mesh conveyor belt can be dried on multiple sides. Not only is the drying work efficiency high, but the aluminum panels after painting can also be dried on multiple sides, avoiding the situation where only one side of the aluminum panels can be dried.

[0004] The existing aluminum panel paint spraying and drying device has a low heat utilization rate during use, and most of the heat is easily discharged directly with the air, resulting in heat waste. It is difficult to recycle and reuse, resulting in high overall energy consumption and insufficient energy conservation and environmental protection. Utility Model Content

Hot air enters the drying cabinet through the air inlet bottom port, passes through the supporting partitions in turn, and is finally discharged through the exhaust top port.

[0008] Furthermore, the multi-tube heat exchanger has heat exchange tubes arranged in an array inside, the top of the heat exchange tubes is connected to the air inlet hood, and the bottom of the heat exchange tubes is connected to the exhaust hood.

[0009] Furthermore, the exhaust hood is connected to the air inlet pipe through a temperature-controlled heater, and the bottom of the air inlet pipe is connected to the air inlet bottom port provided on the drying cabinet.
