Description
Technical field
The utility model relates to a kind of blower fan, specifically, relates to a kind of mixed-flow dedusting fan.
Background technique
Mixed flow fan is the blower fan of the type between axial-flow blower and centrifugal blower.Mixed flow fan combines the feature of axial flow and centrifugal fan, and profile seems more as traditional axial fan.Its wind stress factor is higher than axial-flow blower, and flow coefficient is larger than centrifugal blower, combines the advantage of two kinds of blower fans, and purposes is comparatively extensive.But the mixed flow fan occurred in the market, due to the shortcoming that structure is comparatively complicated, operating noise is large, incoming air area is little, obviously have impact on its usability.
For the problem of mixed flow fan existing in above-mentioned correlation technique, at present effective solution is not yet proposed.
Model utility content
For problems such as mixed flow fan usability above-mentioned in correlation technique are superior not, the utility model proposes a kind of mixed-flow dedusting fan, its structure can be simplified and reduce operating noise, effectively improve the usability of axial fan.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of mixed-flow dedusting fan, comprise the motor be arranged on electric machine support and the fan body be connected with described motor, described fan body comprises blower hood, blower fan base plate and the rotatingshaft be arranged in described blower hood and guide vane, described guide vane is arranged on described rotatingshaft, described guide vane comprises the axial flow leaf fan blade being arranged on described rotatingshaft front end and the centrifugal spiral blade be arranged between described blower fan base plate and described axial flow leaf fan blade, wherein, the periphery of described blower hood is evenly provided with a circle sealing direct current blade.
Further, the inclination angle of described sealing direct current blade is 45 degree.
Further, described blower hood is provided with sealing flange circle.
Further, described guide vane material is aluminum alloy.
The beneficial effects of the utility model: by being provided with a circle sealing direct current blade on the periphery of described blower hood, thus make to form air curtain at blower fan edge, and then reach and effectively ensure that blower fan can not be larger because of exhaust outlet pressure, the problems such as the fan efficiency that formation refluxes and causes is not high, simultaneously, because its sealing effect, the blower fan made is also more stable when rotating.

As shown in figures 1 to 6, a kind of mixed-flow dedusting fan according to embodiment of the present utility model, comprise the motor 2 be arranged on electric machine support 1 and the fan body 3 be connected with described motor 2, described fan body 3 comprises blower hood 4, blower fan base plate 5 and the rotatingshaft 6 be arranged in described blower hood 4 and guide vane, described guide vane is arranged on described rotatingshaft 6, described guide vane comprises the axial flow leaf fan blade 7 being arranged on described rotatingshaft 6 front end and the centrifugal spiral blade 9 be arranged between described base plate 10 and described axial flow leaf fan blade 7, wherein, the periphery of described blower hood 4 is evenly provided with a circle sealing direct current blade 10.
In addition, in a specific embodiment, the inclination angle of described sealing direct current blade 10 is 45 degree, and described blower hood 4 is provided with sealing flange circle 8, and described guide vane material is aluminum alloy.
Conveniently understand technique scheme of the present utility model, below by way of in concrete usage mode, technique scheme of the present utility model is described in detail.
When specifically using, by motor side axial flow leaf wind sheet 7,1500 handkerchief blast being pressed into center centrifugal spiral blade 9, then passed on by centrifugal spiral shape blade 9 and to reach 5000 handkerchiefs, and primitive axis flowing to air-out.Wherein, described mixed-flow dedusting fan is the highest total head 6000 handkerchief, if join secondary motor 2900 turns of aluminum alloy fan blade sheets, its power will improve more than 15%.
In sum, by means of technique scheme of the present utility model, by being provided with a circle sealing direct current blade on the periphery of described blower hood, thus make to form air curtain at blower fan edge, and then reach and effectively ensure that blower fan can not be comparatively large because of exhaust outlet pressure, form backflow and the problem such as the fan efficiency that causes is not high, simultaneously, because its sealing effect, the blower fan made is also more stable when rotating.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
