An air inlet 5 is fixedly arranged in the filter box 1, and the two ends of the fan 2 are respectively connected to the air inlet 5 and the air pipe 3, and then the air outlet 4 is connected to the other end of the air pipe 3, so that the filtered clean air can enter the fever clinic room through the air outlet 4.
[0024] A filter cloth drum frame 6 is rotatably arranged on the outer circumference of the air inlet cylinder 5. Specifically, the filter cloth drum frame 6 includes end rings 601 on both sides, and an annular track 502 connected to the end rings 601 is also arranged on the outer circumference of the air inlet cylinder 5. A plurality of intermediate rings 602 are arranged between the two end rings 601, and then a plurality of axis connecting bars 603 are evenly arranged between the end rings 601 and the intermediate rings 602. At the same time, a plurality of filter cloths 8 are arranged in an annular array on the filter cloth drum frame 6. When specifically arranged, each filter cloth 8 is arranged between two adjacent axis connecting bars 603 and two end rings 601.
[0025] A driving assembly 7 for driving the filter cloth drum frame 6 to rotate is arranged on the filter box 1. Specifically, the driving assembly 7 includes a motor 701 fixed to the outer side of the filter box 1, and the end of the motor 701 extending into the inner cavity of the filter box 1 is connected to a gear 702, and a gear ring 604 meshing with the gear 702 is arranged on one of the end rings 601.
[0026] An air inlet 501 is provided at the upper end of the air inlet cylinder 5 and is aligned vertically with the topmost filter cloth 8. Then, an air inlet channel 9 is fixed on the upper surface of the filter box 1. The lower end of the air inlet channel 9 is aligned vertically with the air inlet 501, and the lower end of the air inlet channel 9 is set close to the two ends of the filter cloth 8.
[0027] During operation of the modular clean ventilation device for emergency fever clinics disclosed in this embodiment 1, the external air is drawn into the filter box 1 through the air inlet channel 9 by the suction action of the fan 2, and then passes through the top filter cloth 8 and enters the air inlet tube 5 through the air inlet port 501, and then passes through the air supply pipe 3 and the air outlet 4 so that the filtered clean air can enter the fever clinic room through the air outlet 4.
[0028] After the ventilation device has been running for a period of time, the driving assembly 7 is started once to rotate the filter cloth drum frame 6 on the outer cylindrical surface of the air inlet cylinder 5 by a certain angle.
