The invention relates to the field of
air purification, in particular to a dust filtering and ventilating device for a communication
base station machine room. The device comprises a fixed outer frame, a ventilation
pipe, a rotating inner frame, a rotating box, a dust filtering
assembly and a ventilation fan. The fixed outer frame penetrates through the wall of the communication
base station machine room, a mounting cavity I is formed in the center, and a through hole I communicated with the mounting cavity I is formed in the side wall; one end of the ventilation
pipe is communicated with the through hole I, and the other end extends to a finger position inside and outside the communication
base station room; the rotating inner frame is rotationally arranged in the mounting cavity I, a mounting cavity II is formed in the rotating inner frame, and a through hole II communicated with the mounting cavity II is formed in the side wall; the rotating box is rotationally arranged in the second mounting cavity, the rotating direction is staggered with the rotating inner frame, and the two ends extend out of the rotating inner frame. The two dust filtering assemblies are located at the two ends of the rotating box correspondingly. The ventilation fan is located in the rotating box and located between the two dust filtering assemblies. The
air purification effect in the communication base
station machine room is good, the pertinence is high, the working
modes are diversified, and the stable and lasting purification performance is achieved.
