Abstract
The utility model discloses a fan impeller mechanism. The fan impeller mechanism comprises a cylindrical axial flow turbine with two ends open. The axial flow turbine is fixedly connected with an impeller mechanism. When the axial flow turbine rotates, the impeller mechanism and the axial flow turbine rotate synchronously, and the axial flow turbine and the impeller mechanism can suck the external air into the axial flow turbine. The fan impeller mechanism has the advantages of high flow and negative pressure and low noise.
Description
Technical field
The utility model relates to a kind of draught fan impeller mechanism, for promoting the ventilation efficiency of air cleaner, ventilating fan or range hood etc.
Background technique
The blower fan of current air cleaning system mainly adopts two kinds of air draft modes, and a kind of is axial-flow blower, and a kind of is centrifugal blower.The feature of axial-flow blower is that flow is large but pressure is little, and that the feature of centrifugal blower is pressure is large, and flow is less.
But, air cleaning system needs be should flow greatly, can form again the blower fan of larger negative pressure, no matter be therefore the blower fan requirement that axial-flow blower or centrifugal blower all cannot meet air cleaning system.
Model utility content
The purpose of this utility model is to provide a kind of draught fan impeller mechanism, has solved the technical problem that cannot reach large flow, large negative pressure of prior art.
For achieving the above object, the utility model has adopted following technical proposal: a kind of draught fan impeller mechanism, comprise the axial flow turbine that is cylindric and both ends open, described axial flow turbine is connected with impeller mechanism, when axial flow turbine rotates, impeller mechanism is synchronizeed and is rotated with axial flow turbine, and axial flow turbine and impeller mechanism can be inner to axial flow turbine by outside air intake.
In above-mentioned a kind of draught fan impeller mechanism, described axial flow turbine comprises two end ring that be arranged in parallel, all has and arrange and be connected with some turbine wheels between two end ring.
In above-mentioned a kind of draught fan impeller mechanism, described impeller mechanism comprises impeller retainer ring and impeller blade, and impeller blade two ends are affixed with impeller retainer ring and end ring respectively.
In above-mentioned a kind of draught fan impeller mechanism, described impeller blade has three and circumferentially evenly distributed along impeller retainer ring.
In above-mentioned a kind of draught fan impeller mechanism, described impeller retainer ring is fixedly connected with motor coupling shaft, and the described shaft axis of motor coupling shaft and the shaft axis of axial flow turbine overlap.
In above-mentioned a kind of draught fan impeller mechanism, described impeller mechanism is arranged on the opening of axial flow turbine.
In above-mentioned a kind of draught fan impeller mechanism, described impeller mechanism has two and be separately positioned on the opening of axial flow turbine.
The beneficial effects of the utility model are: can reach there is large flow, the effect of large negative pressure, and noise is low.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the utility model embodiment 1 structural representation;
Fig. 2 is the utility model embodiment 2 structural representation.
In figure: axial flow turbine 1, impeller mechanism 2, end ring 11, turbine wheel 12, impeller retainer ring 21, impeller blade 22, motor coupling shaft 23.
Embodiment
As shown in Figure 1, a kind of draught fan impeller mechanism, comprise the axial flow turbine 1 that is cylindric and both ends open, described axial flow turbine 1 is connected with impeller mechanism 2, when axial flow turbine 1 rotates, impeller mechanism 2 is synchronizeed rotation with axial flow turbine 1, and axial flow turbine 1 and impeller mechanism 2 can be by outside air intake to axial flow turbine 1 inside.Said mechanism combines the advantage of axial fan and centrifugal fan, has reached the effect that suction negative pressure is large, flow is large, is especially suitable in air cleaning system.
Axial flow turbine 1 comprises two end ring 11 that be arranged in parallel, all has and arrange and be connected with some turbine wheels 12 between two end ring 11.
Impeller mechanism 2 comprises impeller retainer ring 21 and impeller blade 22, and impeller blade 22 two ends are affixed with impeller retainer ring 21 and end ring 11 respectively.Impeller blade 22 can be designed with multi-disc, and in the present embodiment, impeller blade 22 has three and circumferentially evenly distributed along impeller retainer ring 21, and this structure is relatively more firm and have good balance, thereby reduces the noise producing when draught fan impeller mechanism rotates.
Impeller retainer ring 21 is fixedly connected with motor coupling shaft 23, the shaft axis of described motor coupling shaft 23 overlaps with the shaft axis of axial flow turbine 1, thereby further guarantee the balance of whole mechanism, also just reduced noise, when work, the output terminal of driving mechanism passes through motor coupling shaft 23 connecting fan impeller mechanisms, thereby drives this mechanism to rotate.
As a kind of preferred scheme, impeller mechanism 2 is arranged on the opening of axial flow turbine 1, thereby can increase air-breathing flow.
Embodiment 2
As shown in Figure 2, the present embodiment and embodiment's 1 structure and working principle are basic identical, difference is, described impeller mechanism 2 has two and be separately positioned on the opening of axial flow turbine 1, this structure makes whole draught fan impeller mechanism reach Central Symmetry, thereby greatly improved balance, reduced noise.
Above-described embodiment is used for the present invention that explains, rather than this aspect is limited, and in the protection domain of spirit of the present invention and claim, any modification and change that this aspect is made, all fall into protection scope of the present invention.
