Further, the outlet elbow is welded with the blower outlet passenger channel.
Through adopting above-mentioned technical scheme, fan export passenger way lower extreme can be so that heavier dust falls.
(III) advantageous effects
Compared with the prior art, the utility model, following beneficial effect has:
for solving current cement mill exhaust fan because the air intake pipe diameter variable is little and return bend is more for the consumption of exhaust fan is high, and the noise that produces simultaneously is very big, can not satisfy the problem of the user demand that energy-conservation fallen and make an uproar, the utility model discloses a fan import reducing pipe and an export return bend that set up for cement mill exhaust fan increases air intake reducing volume, reduces the use of return bend, greatly reduced the windage, and then make the consumption reduction of exhaust fan, weaken the noise that the exhaust fan during operation produced.
