The utility model provides a spray-drying integrated workshop 100, which generally can include a workshop 10, a spraying device (not shown in the figure) and a drying unit 20. The workshop 10 is selectively used as a spray room or a drying room. The spraying device is installed in the workshop 10 for spraying the product. The drying unit 20 is installed in the workshop 10 and is configured to dry the sprayed product.

[0044] In specific implementation, the workshop 10 can be made of a closed structure made of fiberglass, and the inner walls, ceiling and floor of the workshop 10 are made of a metal grid and a filter cotton 11 is pasted. The workshop 10 is used as a spray room during the spraying process, and the workshop 10 is used as a drying room during the drying process, that is, the spray room and the drying room are overlapping areas in space. The spraying equipment can be an existing spraying robot or other existing spraying equipment. The drying unit 20 can adopt an intelligent temperature control system, which can accurately control the drying temperature and time, achieve uniform drying, avoid overheating or underheating, and improve product quality. The intelligent temperature control system is a prior art, and the structure of the intelligent temperature control system is not repeated in this embodiment.

[0045] After the products to be painted or sprayed, such as vehicles, vehicle parts or other product parts, are transported to the workshop 10, the spraying equipment is turned on to spray the products. After the spraying is completed, the drying unit 20 is turned on to dry the sprayed products.

[0046] The spray-drying integrated workshop 100 of the present invention comprises a workshop 10, a spraying device and a drying unit 20, wherein the spraying device and the drying unit 20 are installed in the workshop 10, and the workshop 10 can be selectively used as a spray room or a drying room, so the present invention adopts a compact space layout design, which minimizes the equipment footprint, making the equipment more suitable for production environments with limited space; through the above design, the present invention integrates the two systems of the spray room and the drying room in the workshop 10, that is, the workshop 10 integrates the spraying and drying functions in the same workshop 10, thereby realizing efficient integration of spraying and drying, and the product can be dried in situ after spraying, thereby realizing continuous operation of spraying and drying, reducing energy loss and improving overall production efficiency and quality; since the use of the present invention does not require the sprayed product to be transported to the drying room, thereby avoiding the possibility that the product may be contaminated or damaged during transportation, the present invention shortens production time and reduces quality risks during transportation.
