Preferably, venetian blind is provided with in the air intake passage of described shell.
Preferably, the outlet end of the air-out passage of described shell is provided with the amplification mouth for strengthening exhaust air rate, and is provided with protective grille in the air-out passage of shell, and protective grille is formed by steel wire and the second steel wire weaving.
Preferably, the oral area of described shell and amplification mouth junction and amplification mouth is all installed and is provided with protective housing.
Preferably, described wheel hub all adopts two-face button mould assembly, and blade and wheel hub fasten fastening mutually.
Preferably, the surface on the blade face of described blade is circular arc, and blade is uniformly distributed in the surface of wheel hub
Preferably, this draught fan impeller diameter between 280 millimeters-1500 millimeters, the adjustable angle of blade 360 degree.
Compared with prior art, the beneficial effects of the utility model are: 1, by improving blower fan blade profile and structure structure, adding blower fan exhaust air rate, reducing energy consumption, also making air-flow smooth sequential more.Simultaneously by improving the Placement of the angle adjustable between fan blade and wheel hub, achieve fan blade and wheel hub separation of produced, and change the setting angle of fan blade according to actual needs, and according to corresponding power of motor adjustment motor model, play effect that is energy-conservation and minimizing overlapping investment.Simultaneously by adopting glass steel material and SMC mould pressing process, except the ventilation enabling blower fan meet under common operating mode uses, cargo sweat environment can also be met and have the usage requirement of the special operation conditions such as remarkable dust.
2, in blower fan structure, wheel hub adopts two-face button mould assembly, blade is coordinated with wheel hub by root taper shank, during installation, each blade being adjusted angle fastens fastening by wheel hub, be convenient to the same blade of size diameter blower fan and the exchange of wheel hub and adjust fan blade angle according to practical application request, both facilitate production and also reduce cost of production, simultaneously user also can adjust angle as required and realizes changing exhaust air rate, need not more ventilating fan, thus also saves user cost.
3, add a blast cap at wheel hub outlet air end, effectively can prevent central position, air port from occurring air-flow wadding stream, thus make the air-flow even more of discharge.
4, an amplification mouth expanded is connected at blower fan support outlet air end, add the stationarity of discharge air-flow and increase exhaust air rate, amplify mouth exhaust outlet simultaneously and install one deck protective housing additional, when also effectively can prevent blower fan stall, sleet and foreign material are entered blower fan, normal operation when interference blower fan starts again.
