The application method of the utility model is as follows：
When blade is installed, blade right end is in the inside of draught fan impeller, and blade left end is in the outside of draught fan impeller, when
When wind turbine brings into operation, motor starts to start, and motor impeller rotates, and as impeller rotates, impeller generates suction, leaf
Wheel is then radiated in the gas extraction outside wind turbine to impeller towards direction blade and gone out, between most of gas flows through blade,
Then the arching trajectory along blade is discharged to the air outlet 12 of wind turbine, between flowing through blade except most of gas, remaining gas
Body can be then hit to the right end of blade, at this time since blade right end is equipped with entrance hole 17, blade right end will not to gas into
Row hinders, which then can directly enter along entrance hole 17 in blast pipe 15, and gas is continually taken out by impeller
It takes to impeller, the gas pressure in impeller constantly raises, and the gas entered in blast pipe 15 is then gases at high pressure, high pressure gas
Body is finally sprayed from air inlet 13, is entered in bellows 3.
Due to being equipped with above 13 port of air inlet into windshield plate 18, under the lattice gear into windshield plate 18, sprayed from air inlet 13
The gases at high pressure gone out then can direct projection in supply air wheel 6, supply air wheel 6 is subject to the impact of gases at high pressure that can then rotate, with air-supply
Wheel 6 rotates, and the gases at high pressure constantly projected from air inlet 13 are eventually sprayed to promotion slot 9, and promote 9 cell wall one of slot
Side is straight plane 10, and the cell wall opposite with straight plane 10 is inclined-plane 11, and 11 area of inclined-plane is more than straight 10 area of plane, enters to and push away
Gases at high pressure in dynamic slot 9 then can be largely acted on to inclined-plane 11, and inclined-plane 11 is tilted towards clockwise direction, gases at high pressure
Clockwise thrust can then be formed to the promotion on inclined-plane 11, as supply air wheel 6 constantly rotates, gases at high pressure to pushing away one by one
Dynamic slot 9 constantly promotes, then can ensure that supply air wheel 6 carries out stable rotate clockwise.
As supply air wheel 6 is rotated clockwise, supply air wheel 6 can then form clockwise vortex in its outer ring, in bellows 3
Generation suction, the gases at high pressure in blast pipe 15 are constantly sucked into bellows 3, so as to by the portion gas in impeller it is continuous
It draws to blast pipe 15, improves the flow velocity that gas enters blast pipe 15, the vortex of 6 outer ring of supply air wheel is passing through air outlet guard board 19
When, then can be obstructed by the flange 21 of 19 one end of air outlet guard board, make vortex agglomerate gases at high pressure by air outlet 12 continually
Be admitted in discharge pipe 14, finally discharged from leadout hole 16, the gases at high pressure discharged from leadout hole 16 then can directly with from blade
Between the gases at high pressure discharged converge, the gases at high pressure discharged from leadout hole 16 are pressurized by supply air wheel 6, therefore from leadout hole 16
The high-pressure gas pressure of discharge is significantly greater than the high pressure gas from the high-pressure gas pressure discharged between blade, discharged from leadout hole 16
Body can make by pressure itself to being aided in from the gases at high pressure discharged between blade from the high pressure gas discharged between blade
Body flow velocity increases, and further improves the efficiency of supply of gases at high pressure.
It understanding in summary, the utility model can guide the gas impacted to blade right end by entrance hole 17,
It enables its flow into blast pipe 15, so as to be utilized, blade right end will not hinder the portion gas, obtain gas resource
To efficiently using, ensure the dispatch amount of gas, and the gas entered in blast pipe 15 can drive supply air wheel 6 to rotate, and blow
In the case of 6 rotation of wheel, supply air wheel 6 can generate vortex, and 3 inside of bellows is made to generate suction, further improves the flow velocity of gas,
The efficiency of supply of the portion gas is improved, finally can pass through the superpower flow velocity band of itself from gases at high pressure derived from leadout hole 16
Move the efficiency of supply for from the gases at high pressure discharged between blade, improving all gas.
It is straight panel into windshield plate 18, the gases at high pressure that can ensure to spray from blast pipe 15 keep the state of straight line to be sprayed
It penetrates, gases at high pressure is made to obtain perfect utilization, ensure the rotation of stablizing of supply air wheel, and several be uniformly distributed is equipped with into windshield plate 18
Ventilation hole 20, the presence of ventilation hole 20 can enable the gas into 18 top of windshield plate and the gas into 18 lower section of windshield plate
It crosses, will not rotate the vortex formed to supply air wheel 6 into windshield plate 18 causes to obstruct, and ensures playing wind-guiding effect into windshield plate 18
Vortex flow will not be hindered while fruit.
Air outlet guard board 19 is equipped with flange 21 adjacent to one end of supply air wheel 6, and flange 21 is turned down towards 12 port of air outlet lower section,
It is connected between flange 21 and air outlet guard board 19 by 22 transition of curved portion, between air outlet guard board 19, flange 21 and curved portion 22
Length summation is less than rotation spacing 8, and the presence of curved portion 22 can effectively reduce windage, enable gases at high pressure more smoothly
It is admitted in discharge pipe, improves the efficiency of supply of gas.
Blade right-hand end is equipped with the diversion channel 23 to connect with entrance hole 17, and diversion channel 23 is in bowl-shape, bowl-shape shunting
Slot 23 makes entrance hole be more easy to receive impact to the gas of blade right end, and 23 periphery of diversion channel is equipped with the air dam 24 in arcuation,
Air dam 24 and 23 intersection of diversion channel are formed with the segmentation side of wire along 25, and the gas impacted to blade right end can be effective
It is divided into blade right end middle part and both sides three parts, makes all gas that can be utilized effectively, be not in waste
Situation.
