Specific embodiment
The technical solution of the utility model is further described below in conjunction with the accompanying drawings, but claimed scope is not limited to
It is described.
As shown in figure 1, a kind of feed back device with the wind, including housing 1；The housing 1 be hollow structure, the head of the housing 1
Tail two ends are respectively arranged with air inlet 2 and air outlet 4, and the deflector 3 being open to windward side, institute are provided with the air inlet 2
State and the pressure reductor 5 being open to face with the wind is provided with air outlet 4, the inside of the housing 1 is additionally provided with nozzle at air inlet 2
6.The technical program is provided with nozzle 6 by being arranged on deflector 3 and pressure reductor 5 in housing 1, so as to make lowpressure stream
Body injects high-pressure fluid.When in use, directly according to the cross sectional dimensions and air outlet of smoke exhauster bore making of civilian flue
It is its corresponding to feed back device with the wind, then will feed back device with the wind and be arranged on flue and air outlet of smoke exhauster relevant position, in work
When making, enclosure interior forms diffuser, air outlet 4 and expansion near 2 one sections of formation changeover portions of air inlet in the mounting portion of nozzle 6
Diversion section is formed between scattered section, is exactly in fact from flue after feedback device with the wind described in the utility model is installed on flue
The inside is taken out a part of wind and sends flue back to again after feedback with the wind device, so that air inlet 2 is put down with the flow at air outlet 4
Weighing apparatus, the blast conversion in flue；In theory, the blast at air inlet 2 is equal to the blast at air outlet 4, to using oil pumping
Cigarette machine does not just produce impact；In actual applications, due to the various factors pair such as roughness of the shape of housing 1, length, and inwall
The impact of the air (fluid) for circulating within the case 1, forms an impact factor of circulation, is represented with feedback factor, but due to
Feedback factor is less than being equal to 1, therefore to not producing considerable influence using smoke exhaust ventilator, that is to say, that the wind at air inlet 2
Crimping is bordering on the blast at air outlet 4.Therefore device with the wind is fed back using described in the utility model, efficiently solves civilian flue
The problem of single household down draught, can use safely in the environment of high-pressure side pressure is less than or equal to 0.5MPa.
The outside of nozzle 6 is located on the housing 1 and is additionally provided with negative suction inlet 7.So, can form negative at the inner nozzle 6 of housing 1
Nip, further prevents from producing down draught in housing 1.
The inner side of the housing 1 is provided with raised 8, and raised 8 initiating terminal is connected with negative suction inlet 7.Described raised 8 in housing
The diffuser of horn-like structure is formed on 1 inside, down-draught-proof effect is further improved.
Adpting flange 9 is provided with the air inlet 2 and air outlet 4.So, when in use, can directly by connecting
Acting flange 9 is arranged on housing 1 on flue using securing members such as bolts, easy installation and removal.
The deflector 3 is the arcwall face structure towards air inlet 2, and arcwall face is connected the inwall of one end with air inlet 2
It is tangent with the inwall of housing 1, arcwall face away from the one end of air inlet 2 straight up.As such, it is possible to so that the wind inside flue one
The stream of lease making air inlet 2 enters housing 1, flows out from air outlet 4 after the inner chamber of housing 1, and another part continues on the outside edge of deflector 3
Flue to dirty.
The pressure reductor 5 is the arcwall face structure towards air outlet 4, and arcwall face is connected the inwall of one end with air outlet 4
It is tangent with the inwall of housing 1, arcwall face away from the one end of air outlet 4 straight down.Using the technical program, flow out from air outlet 4
The wind for coming at most forms a whirlpool with the wind in flue below pressure reductor 5, without producing down draught phenomenon.
The nozzle 6 is frustum cone structure, and the outside diameter of round platform is 160mm-200mm, and the end diameter of round platform is 80mm-
120mm, and round platform extends the coning angle to be formed for 15 ° -20 °.In actual applications, coning angle preferentially takes 17 °, through a large amount of examinations
Checking is bright, has good down-draught-proof effect using 17 °.
A diameter of 150-200mm of the negative suction inlet 7.
The lateral surface of the deflector 3 is 40cm-60cm with the distance at the center of negative suction inlet 7.
Described 1 outer shape is circular, square or rhombus.In this actual fabrication, can according to needs of production and
The requirement of different use occasions designs different contour structures.Such as, circular configuration can be made using pipe；Square structure can be adopted
Made with square tube；Diamond structure can be welded using steel plate.
As shown in Fig. 2 the utility model adopts Venturi tube principle, when gas flows inside Venturi tube, in pipeline
Most narrow place, dynamic pressure (velocity head) reaches maximum, and static pressure (Resting Pressure) reaches minimum of a value, the speed of fluid because
Rise for the reduction of flow cross area, entirely shoving will experience pipe reductions process within the same time, thus pressure
Power is also reduced in the same time, and then produces pressure reduction, and this pressure reduction provides an external suction to fluid.Smoke exhaust ventilator is gone out
Mouth is connected on the narrow place of doing of Venturi tube, i.e., at the negative suction inlet 7 shown in Fig. 1, so as to form negative pressuren zone at negative suction inlet 7.Then by cigarette
Air in road 10 sends into device with the wind described herein, allows air to return in flue 10 through device with the wind, that is, pass in and out flue
The air pressure size and wind speed size of 10 air outlets with regard to very little, that is, reach with the relation of the air outlet of smoke exhauster for being in negative pressuren zone
To feedback equalization, by having done a nozzle 6 at air outlet of smoke exhauster, the power of its nozzle 6 is exactly the high pressure in flue
Gas is flow backwards, therefore, as long as considering that this flows backwards the flow velocity of gas, by arranging deflector 3 at air inlet 2, increased stream
Body flow, arranges pressure reductor 5 at air outlet 2, reduces outlet pressure, so that air inlet 2 and the pressure at air outlet 4 are flat
Weighing apparatus, so as to reach the purpose for solving down draught and smooth discharge oil smoke.Efficiently solve kitchen chimney flue and fall cigarette and civilian flue single household
The problem of down draught, also can be used to need feeding in the production of high-pressure fluid.
