Abstract
The utility model discloses a scavenger fan wind wheel, this wind wheel by the base, go up frame and a plurality of blades, the blade is the arc to erect around the base, the upper ledge erects the other end at the blade, base, last frame and blade integrated into one piece, be equipped with the air inlet duct between blade and the blade, be equipped with the fixed axle trepanning on the base, be equipped with at least one air inlet duct on the base. The utility model discloses a base, go up frame and blade integrated into one piece, improved scavenger fan wind wheel's quality, also reduced product cost, and be equipped with the air inlet duct on the base for the wind wheel can admit air and pump drainage gas in positive front side, thereby has increaseed scavenger fan wind wheel's pump drainage gas effect.
Description
Technical field
The utility model relates to pumping oil flue gas equipment, relates in particular to a kind of Wind wheel of air change fan.
Background technology
At present, the weak point of existing pumping oil flue gas equipment is, the wind wheel in ventilation fan equipment just by side blade withAir inlet duct between blade carrys out exhaust, makes the poor effect of pumping oil flue gas.
Utility model content
For above-mentioned the deficiencies in the prior art, it is a kind of simple in structure, easy to use that the utility model provides, and smoke discharging effectGood Wind wheel of air change fan.
In order to realize above-mentioned technical purpose, the technical scheme that the utility model adopts is:
A kind of Wind wheel of air change fan, is characterized in that, this wind wheel is made up of base, upper frame and some blades, and described blade is arc,And be erected at the surrounding of base, described upper frame is located at the other end of blade, and described base, upper frame and blade are one-body molded,Between described blade and blade, be provided with air inlet duct, described base is provided with fixed axis trepanning, and described base is provided with at least one air inletGroove.
Can find out from technique scheme, the utility model is one-body molded by base, upper frame and blade, has improved ventilation fanThe quality of wind wheel, has also reduced product cost; And on base, be provided with air inlet duct, make the wind wheel can air inlet in positive front side and take outExhaust, thus the exhaust effect of Wind wheel of air change fan strengthened.
