A venting muffler for a magnetic levitation blower

Abstract

The utility model discloses a kind of venting silencers for magnetic levitation blower, belong to fan equipment technical field, including outer sound-absorbing pipe and inner sound-absorbing pipe, and by the detachable connection with the venting pipe of magnetic levitation fan of connecting mechanism consisting of fixed ring, dovetail tenon slot and clamp lock is realized, the inner wall top of the inner sound-absorbing pipe is fixed with the cone gas shunt plate of spiral flow guide groove, composite heat preservation mechanism consisting of honeycomb metal frame, fibre cotton and aluminium foil reflector plate is arranged between the outer sound-absorbing pipe and inner sound-absorbing pipe, the bottom of the silencer is also provided with the drain pipe that is connected with inner sound-absorbing pipe and passes through outer sound-absorbing pipe.The utility model solves the problem of complicated installation, unstable connection of silencer in the prior art by the above connecting mechanism, and through the synergistic effect of composite heat preservation mechanism and automatic drain pipe, the problem of icing damage or performance decline caused by insufficient heat preservation, condensate accumulation under cold environment of silencer is solved.
