Embodiment
[0036] In industrial production sites, there are many sites that require forced air supply. The locations or facilities that require air supply are always in a state of motion. A kind of air supply volume that can reach 2,000 to 10,000 cubic meters per hour is required, and can be used for a long time. Air supply for continuous operation.
[0037] This embodiment provides a flexible air duct retractable device for air supply, such as Figure 1-8 As shown, it includes an air duct reel assembly, a flexible air duct 8, two reel seats, a rotating air intake assembly 2 and a rotary drive assembly 12 for driving the air duct reel assembly to rotate.
[0038] When it is in use, it cooperates with the air supply fan to send air into the air inlet of the rotary air inlet assembly 2, and then into the flexible air duct 8 through the air duct reel assembly, and the air outlet of the flexible air duct 8 is located at the place or facility office.
[0039] Specifically, in this embodimen...
