A kind of air-flow rectifier structure
Technical field
The utility model relates to air-flow commutation technique field in the air channel, relates to a kind of air-flow rectifier structure that can be used for hot wind generating device especially.
Background technology
Existing hot wind generating device all is to use the bending-type air channel, thereby this air channel is also bigger than the cyclone that causes greatly, eddy current, flow-disturbing etc. along the obstruction on air-flow road, makes the bigger reverse pressure of existence in the air channel.At present; For this type of problem generally all is to solve through increasing air output and blast pressure; And increase air output and just necessary rotating speed and the wind cutting amount that strengthens Air Blast fan of blast pressure, cause very big energy waste like this, and increased the noise of fan.
The Chinese patent notification number is that CN201743620U discloses a kind of collection air channel that the deduster intake is measured that is used for; Comprise the air channel body; One end of air channel body is bell-mouthed air intake pipeline section, and the other end of air intake pipeline section is connected with the rectification pipeline section through flange, is connected with the rectification castor that screen cloth is set in the middle of the rectifying tube intersegmental part; The rectification pipeline section is connected with the measurement pipeline section through flange, measures the pipeline section outlet and is used to connect deduster.The air channel of syllogic assembling is adopted in this collection air channel; The air intake pipeline section of toroidal imports the air channel with air and forms air-flow; Air-flow passes through the rectification castor of rectification pipeline section again; Screen cloth on the rectification castor can make the rotation of suction and more in disorder air-flow form straight line and uniformly and stably through the air channel, obtain stablizing straight air-flow better.Though the rectification castor in this collection air channel has good arrangement to obtain stablizing the effect of straight air-flow, it is a network structure, is easy to accumulate dust and stops up the air channel.
The utility model content
To the shortcoming of prior art, the utility model provides a kind of air-flow rectifier structure, through setting up the rectification position at the air outlet place, makes disorderly air-flow form uniform and stable air-flow and discharges, simple in structure and cleaning convenience.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of air-flow rectifier structure comprises the rectifier structure body, and said rectifier structure body is provided with air inlet and air outlet, also comprises the rectification position of being located at the air outlet place.Wherein, the incoming air area of said air inlet is greater than the axial area of air outlet.
Alternatively, said rectification position comprises some wind-guiding muscle, and the interval between the wind-guiding muscle is communicated with air outlet.When the air-flow of disorder gets into when running into the wind-guiding muscle, air-flow moves along the wall of wind-guiding muscle, the wind-guiding muscle stop and guide functions under, form uniform and stable air-flow.The wind-guiding muscle can also play the effect of heat radiation, has reduced the operating temperature of generator, prolongs its service life.
Preferably, said wind-guiding muscle radially and be uniformly distributed in air outlet, such structural design can play the better effect of water conservancy diversion air-flow more uniformly.
As improvement, said rectifier structure body is provided with the plurality of fixed ear, is convenient to this air-flow rectifier structure is fixed on through fixtures such as screws on the generator that needs to use, and is simple and convenient.
Non-directional air-flow because of factors such as air flue bending form when the air-flow of disorder gets into the intrinsic air channel of rectifier structure, passes through the rectification position at air outlet place; Because the rectification position is provided with some wind-guiding muscle; Interval between the wind-guiding muscle is connected with air outlet, the wind-guiding muscle stop and guide functions under because the wind-guiding muscle distributes radially and evenly; Disorderly air-flow flows along the wind-guiding muscle, finally forms uniform and stable air-flow and discharges.This air-flow rectifier structure has solved because of factors such as air flue bending form nondirectional air-flow and has produced the problem that cyclone, eddy current, flow-disturbing etc. increase the air channel reverse pressure.
Compared with prior art, the beneficial effect of the utility model is:
The utility model air-flow rectifier structure, it is simple in structure and cleaning is convenient, through setting up the rectification position at the air outlet place; Make of the structure direction motion of in disorder air-flow according to the rectification position; Discharge thereby form uniform and stable air-flow, reduced the flow impedance in the rectifier structure body air channel, air-out is smooth and easy; Improved air output simultaneously, under the situation that air output equates, reduced air output to have saved the energy.

The specific embodiment
Below in conjunction with the specific embodiment the utility model is further described.
Extremely shown in Figure 4 like Fig. 1 is the embodiment of the utility model air-flow rectifier structure, comprises rectifier structure body 10, and rectifier structure body 10 is provided with air inlet 11 and air outlet 12, also comprises the rectification position 20 of being located at air outlet 12 places.Wherein, the incoming air area of air inlet 11 is greater than the axial area of air outlet 12.This air-flow rectifier structure has solved because of factors such as air flue bending form nondirectional air-flow and has produced the problem that cyclone, eddy current, flow-disturbing etc. increase the air channel reverse pressure.
In the present embodiment, rectification position 20 comprises some wind-guiding muscle 21, and the interval 22 between the wind-guiding muscle 21 is communicated with air outlet 12, and wind-guiding muscle 21 radially and be uniformly distributed in air outlet 12.The non-directional air-flow that forms because of factors such as air flue bendings, when the air-flow of disorder got into the air channel in the rectifier structure body 10, air-flow moved along the wall of wind-guiding muscle 21, wind-guiding muscle 21 stop and guide functions under, form uniform and stable air-flow.Wind-guiding muscle 21 can also play the effect of heat radiation, has reduced the operating temperature of generator, prolongs its service life.
When the air channel in the air-flow entering rectifier structure body 10; The non-directional air-flow that forms because of factors such as air flue bendings is through the rectification position 20 at air outlet 12 places, because rectification position 20 is provided with some wind-guiding muscle 21, the interval 22 between the wind-guiding muscle 21 is connected with air outlet 12; Wind-guiding muscle 21 stop and guide functions under; Because wind-guiding muscle 21 distributes radially and evenly, disorderly air-flow flows along wind-guiding muscle 21, finally forms uniform and stable air-flow and discharges.
For the ease of this air-flow rectifier structure is fixed on the generator that needs to use through fixtures such as screws, on rectifier structure body 10, be provided with plurality of fixed ear 13.Present embodiment is provided with six fixedly ears 13.
This air-flow rectifier structure, it is simple in structure and cleaning is convenient, through setting up rectification position 20 at air outlet 12 places; Make of the structure direction motion of in disorder air-flow according to rectification position 20; Discharge thereby form uniform and stable air-flow, reduced the flow impedance in rectifier structure body 10 air channels, air-out is smooth and easy; Improved air output simultaneously, under the situation that air output equates, reduced air output to have saved the energy.
