Description
Technical field
Blower fan technical field is the utility model is related to, in particular, the utility model is related to a kind of the double of balanced air quantity
Laminar draught fan impeller.
Background technology
Blower fan is an indispensable important component in exhaust treatment system, and existing blower fan is mostly single layer structure,
Air outlet air volume adjustment is uneven, and blower interior is also easy to vortex phenomenon occur, has a strong impact on the efficiency of blower fan.
The content of the invention
The purpose of this utility model is effectively to overcome the shortcomings of above-mentioned technology, there is provided a kind of two-layer equation wind of balanced air quantity
Machine impeller, the two-layer equation draught fan impeller are used tuyere air volume and are evenly distributed, slow down vortex phenomenon, improve fan efficiency.
What the technical solution of the utility model was realized in：A kind of two-layer equation draught fan impeller of balanced air quantity, it is improved
Part is：Including wheel hub, back shroud, blade, front shroud and median septum；
Described wheel hub is fixed at the center of back shroud, for driving back shroud to rotate；Described blade is fixed on institute
On the back shroud stated, blade together rotates with described back shroud；
Described front shroud is fixed on the top of the blade, and described median septum is fixed on the front shroud and bonnet
Between plate, described front shroud and median septum are used for after the gas for entering blower fan is cut into two parts, are formed respectively two layers
Air channel is simultaneously directed to air outlet.
In such a configuration, in a ring, and the diameter of the top of front shroud to bottom is gradually reduced the front shroud.
In such a configuration, in a ring, and the diameter of the top of back shroud to bottom is gradually reduced the back shroud.
In such a configuration, the front shroud, the center of back shroud and wheel hub are centrally located on same straight line.
The beneficial effects of the utility model are：The gas entered at air inlet is straight by the effect of median septum
Connect and cut into two parts, form two layers of air channel, and be directed to air outlet, so that the air volume adjustment of air outlet is uniform, slow down
Vortex phenomenon, fan efficiency is improved, reduce fan energy consumption, save fan operation cost.
【Brief description of the drawings】
Fig. 1 is cross-sectional view of the present utility model.
【Embodiment】
The utility model will be further described with reference to the accompanying drawings and examples.
Shown in reference picture 1, a kind of two-layer equation draught fan impeller for balanced air quantity that the utility model discloses, including wheel hub 10,
Back shroud 20, blade 30, front shroud 40 and median septum 50；Described wheel hub 10 is fixed at the center of back shroud 20, is used for
Back shroud 20 is driven to rotate；Described blade 30 is fixed on described back shroud 20, and blade 30 is with described back shroud 20 1
With rotation；Described front shroud 40 is fixed on the top of the blade 30, and described median septum 50 is fixed on the front shroud
Between 40 and back shroud 20, described front shroud 40 and median septum 50 are used to the gas for entering blower fan cutting into two parts
Afterwards, two layers of air channel is formed respectively and is directed to air outlet.The front shroud 40, the center of back shroud 20 and the centre bit of wheel hub 10
In on same straight line.
In the present embodiment, in a ring, and the diameter of the top of front shroud 40 to bottom is gradually reduced the front shroud 40；
In a ring, and the diameter of the top of back shroud 20 to bottom is gradually reduced the back shroud 20；Also, front shroud 40 and back shroud
20 section is in symmetrical arcuate structure, is easy to implement wind-guiding.
By above-mentioned structure, the gas entered at air inlet, it is cut directly into by the effect of median septum 50
Two parts, two layers of air channel is formed, and be directed to air outlet, so that the air volume adjustment of air outlet is uniform, it is existing to slow down vortex
As improving fan efficiency, reducing fan energy consumption, save fan operation cost.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to the utility model
Limitation.In technological thought category of the present utility model, various modifications and modification, the ordinary skill of all this areas can occur
Retouching, modification or the equivalent substitution that personnel are made as described above, belong to the scope that the utility model is protected.
