Abstract
The utility model relates to an energy-saving fan special for an oil gun, whose spiral casing is additionally provided with a cleaning port and a discharge port. The curvature radius of the cambered surface of a blade on an impeller is enlarged (1.2-1.7 times of the normal value), and the contact angle between the blade and the back plate of the impeller is enlarged. The contact angle is 50-65DEG. The wind pressure can be increased by the dragging of a same electromotor. Meanwhile, the utility model can achieve the specific requirements of operating in the harsh environment. The utility model has the advantages of convenient maintenance, long service life, and low ambient noise.
Description
The utility model relates to a kind of oil gun energy-saving blower fan, and it belongs to the centrifugal pump class that is used to compress.
The present domestic blower fan that does not still have the oil burner special use, and general blower fan often blast is not high enough and be difficult to cleaning, energy consumption is higher simultaneously, also It does a lot of damage for noise.
The purpose of this utility model provides a kind of blower fan of oil gun special use, and it should can obtain to improve the effect of blast with better simply architecture advances, has the advantage that is easy to scarfing cinder dedusting, energy efficient, reduction noise simultaneously.
Oil gun energy-saving blower fan contains spiral case 1 and impeller 2, and its technical characteristics is: described spiral case 1 top is provided with the slag removal mouth 11 of manually folding, and its bottom is provided with the slag exhausting mouth 12 of manually folding; The cambered surface radius of curvature of described impeller 2 its each blades is 1.2～1.7 times of similar fan blade, and the wrapping angle α of blade and impeller backboard 21 is 50 °～65 °.
Accompanying drawing is a configuration diagram of the present utility model.
Among the figure, 1 spiral case, 2 impellers, 11 slag removal mouths, 12 slag exhausting mouths, 21 impeller backboards.
The most direct effect that increases impeller blade cambered surface radius of curvature is suitably to increase lobe numbers under the prerequisite that does not change impeller size, add the wrapping angle (this wrapping angle is about 45 ° usually) that increases blade and impeller backboard, even so do not change the rated power of dragging motor, also can reach the purpose that improves blast easily, thereby satisfy the demand of oil burner air feed better.
In addition, the molten aluminium open hearth of making thermal source with oil burner generally adopts the blower fan of 90 ° of exhaust outlets.The draught fan impeller of working under this class environment will soon amass full dust grease, long slightly then disequilibrium of time, vibrate strong more, noise is also big more, sometimes even the danger that burns out motor arranged.The utility model is proceeded from the reality, and is provided with slag removal mouth and slag exhausting mouth in the top and the lower part of volute of blower.Open slag removal mouth, the special implement that is equipped with other can be removed the band oil laying dust on each blade more conveniently, and turns on slag exhausting mouth, the band oil laying dust that goes out is clearly discharged, being tantamount to prolong the life-span of blower fan like this, significantly having reduced ambient noise again, is to kill two birds with one stone.
