Abstract
The utility model discloses a circular pipeline draught fan. The circular pipeline draught fan comprises an enclosure (1) and a wind wheel (2) installed in the enclosure (1), wherein a plurality of wind guide sheets (3) are arranged on the inner wall of the wind outlet end (1.1) of the enclosure (1), the wind guide sheets (3) are vertically connected with the inner wall of the wind outlet end (1.1), and each wind guide sheet (3) comprises an arc wind guide sheet (3.1) and a rhomboid wind guide sheet (3.2) connected at one end of the arc wind guide sheet (3.1). The circular pipeline draught fan has the advantages of large blast capacity and high wind pressure.
Description
Technical field
The utility model relates to the blower fan technical field, is specifically a kind of circular pipe blower fan.
Background technique
A kind of circular pipe blower fan is arranged at present, and it comprises casing and is arranged on the wind wheel in casing.The blower fan of the type in use, the wind major part of exporting through the vane group of wind wheel is delivered directly to the exhaust outlet place of blower fan, but also some is to enter into the exhaust outlet place after first touching the inwall at casing exhaust outlet place again, so just can not be led to this part wind, just be greatly reduced air quantity and the blast of blower fan.
The model utility content
Technical problem to be solved in the utility model is that the circular pipe blower fan that a kind of air quantity and blast are larger is provided.
For solving the problems of the technologies described above, the circular pipe blower fan that the utility model provides, it comprises casing and is arranged on the wind wheel in casing, the inwall of the outlet air end of described casing is provided with a plurality of guide vanes, the vertical connection of inwall of described guide vane and outlet air end, described guide vane consists of arc guide vane and the parallelogram guide vane that is connected to arc guide vane one end.
After adopting above structure, the utility model compared with prior art, have advantages of following: because be provided with a plurality of guide vanes on the inwall of outlet air end, therefore can be to the vane group from the blower fan wind wheel wind out led, avoided touching with the inwall of casing outlet air end, effectively increased air quantity and blast.
As improvement, the quantity of described guide vane is four, and these four guide vanes form circumference uniform distribution along the inwall of outlet air end, and the guide vane that forms circumference uniform distribution more can be led to wind.
The accompanying drawing explanation
Fig. 1 is the side-looking structural representation of the utility model circular pipe blower fan.
Fig. 2 is the structural representation of the utility model circular pipe blower fan.
Fig. 3 is the structural representation after the utility model circular pipe blower fan removes the part casing.
Shown in figure: 1, casing, 1.1, outlet air end, 2, wind wheel, 3, guide vane, 3.1, the arc guide vane, 3.2, the parallelogram guide vane.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
The utility model circular pipe blower fan, it comprises casing 1 and is arranged on the wind wheel 2 in casing 1.Unlike the prior art, the inwall of the outlet air end 1.1 of described casing 1 is provided with a plurality of guide vanes 3.The vertical connection of inwall of described guide vane 3 and outlet air end 1.1, described guide vane 3 consists of arc guide vane 3.1 and the parallelogram guide vane 3.2 that is connected to arc guide vane 3.1 1 ends.
As the improvement project of the present embodiment, the quantity of described guide vane 3 is four, and these four guide vanes 3 form circumference uniform distribution along the inwall of outlet air end 1.1.
Circular pipe blower fan of the present utility model arranges guide vane because of the inwall at outlet air end, thus can be to the vane group from the blower fan wind wheel wind out led, wind is concentrated from outlet air end directly out, effectively increased air quantity and blast.
