In the embodiment of the present utility model, an axial flow device with bidirectional circulation is provided, which includes two fans 100, a base 110 and a dust screen 120, wherein the base 110 is in front-back communication, the two fans 100 are respectively installed at the front end and the rear end of the base 110, the two fans 100 are opposite in direction, two opposite clamping plates 200 are arranged at the upper end of the inner side wall of the base 110, the clamping plates 200 comprise a high plate 210 and a low plate 220, the upper end of the dust screen 120 is clamped between the high plate 210 and the low plate 220, a transverse groove 300 is further arranged at the lower end of the inner side wall of the base 110, a locking table 310 is arranged in the transverse groove 300, and the lower end of the dust screen 120 is installed in the locking table 310.
Specifically, the bidirectional ventilation of air is achieved by installing the fans 100 in opposite directions at the front and rear ends of the base 110, respectively. When the forward direction flow is required, the fan 100 at one end of the base 110 is started, the fan 100 at the other end is turned off, and when the reverse direction flow is required, the fan 100 at one end of the base 110 is turned off, and the fan 100 at the other end is started. The design not only improves the air circulation efficiency, but also can better adapt to the ventilation requirements of different occasions, and improves the practicability of the axial flow device. By providing the clip plate 200 and the locking stage 310, a stable installation of the dust screen 120 on the base 110 is achieved.
