The air circulation purification
assembly of the dust-free room comprises an air supply main
pipe and a plurality of supporting plates, the two ends of each supporting plate are fixedly connected with flow dividing pipes, each flow dividing
pipe communicates with the air supply main
pipe, and the ends, away from the air supply main pipe, of the flow dividing pipes are connected with filtering
branch pipes through quick
assembly mechanisms; the two ends of the air supply main pipe are fixedly connected with an air inlet pipe and an
exhaust pipe correspondingly, a flow control
assembly is arranged on the inner side of the air inlet pipe and used for controlling the flow of air entering the air supply main pipe, and the quick assembly mechanism comprises a bearing arc plate, a positioning arc plate, a linkage frame, a center shaft rod and a plugging disc. According to the invention, through the structural cooperation of the
shunting pipe, the quick-mounting mechanism and the filtering
branch pipes, the non-stop replacement of the corresponding filtering
branch pipes can be realized under the condition that the continuous air circulation of the dust-free room is not influenced, and the influence on the production progress of personnel in the dust-free room is avoided.
