Description
Technical field
The present invention relates to a kind of blower, more precisely a kind of special fan.
Background technique
Dumper simply understands to be exactly to have many advantages, such as environmental protection, beautiful and reduction secondary pollution for driving with electric power, is phase
Cyclization is defended system department and is used.Currently on the market such dumper quite kept a public place clean industry welcome.The blower of existing dumper
Due to being influenced by friction factor and windage factor, the high-speed cruising of the blower of dumper is limited, the blower of dumper is caused
Suction cannot reach the level of anticipation, be unable to the sundries that quick adsorption is heavier or density is excessive.Under normal circumstances flabellum with turn
Axle clamp angle is bigger, and the suction of generation is bigger, but flabellum will generate relatively high wind after being greater than 45 degree with shaft angle
Resistance, to make the spin down of flabellum.

In order to further realize the purpose of the present invention, following technical scheme: the side peace of the air intake cover can also be used
Fill several fins being arranged in a row.The top mounting flange of the air intake cover.
The present invention has the advantages that the plane of baffle of the invention with different gradient, the first inclined-plane and motor is defeated
Angle between shaft is β, and β=78 degree, the angle between the second inclined-plane and the output shaft of motor is γ, and γ=61 degree make to lead
Flow block prior to flabellum cutting steam, cooperate frontal airflow after the guiding of baffle with flabellum, plane where making flabellum with
Angle between the output shaft of motor is α, and whens α=46 degree still keeps lower windage, is tested by experiment, baffle and fan
Compared to the flabellum of not baffle after leaf combination, the wind-force generated in the identical situation of power improves 15% or so, thus
Substantially increase the wind speed of blower under equal-wattage.We conducted independent tests to turn when on only baffle access motor
In the case that speed is 500 revolution per seconds, the wind-force of generation is metre per second (m/s), the angle where flabellum between plane and the output shaft of motor
For α, when whens α=46 degree is independently accessed on motor, in the case that revolving speed is 500 revolution per seconds, the wind-force of generation is 8 metre per second (m/s)s, and
Flabellum in conjunction with baffle after access motor when, revolving speed be 500 revolution per second in the case where, the wind speed of generation is 16 metre per second (m/s)s,
Much higher than the addition of the independent effect of the two.Output shaft of the invention increases tantalum and bismuth on the basis of ordinary steel, it has been found that
Tantalum and bismuth can be substantially reduced the force of sliding friction of steel surface when being added in steel at the same time, to reduce heat production, improve motor
Revolving speed.It is confirmed through overtesting, when tantalum is separately added in steel, without the force of sliding friction effect for being substantially reduced steel surface.When
When bismuth list is separately added in steel, the force of sliding friction of steel surface reduces by 1% or so, is added in steel after tantalum and bismuth combine
When, being substantially reduced occurs in the force of sliding friction of steel surface, and different, the force of sliding friction reduction of steel surface is matched according to tantalum and bismuth
Data are all larger than 2%, when tantalum: 6.5% and bismuth: when 3.63%, the force of sliding friction reduced rate of steel surface reaches the 5% of peak value,
The motor equal-wattage limit inferior revolving speed of manufactured output shaft improves 20% or so；To substantially increase the absorption of special fan
Ability.The present invention also has the advantages of compact structure, low manufacturing cost and easy to use.
