Specific embodiment
The air curtain structure of the present embodiment mainly includes blower 2 and air hose 1, is formed with S-shaped air duct, S-shaped wind inside air hose 1
Road includes interconnected top air duct 1-4 and lower part air duct 1-5, and the area of top air duct 1-4 is greater than the face of lower part air duct 1-5
Product；One end of top air duct 1-4 has air inlet, is connected to the air outlet of blower 2；Bottom duct has air outlet 1-3, under
Portion air duct 1-5 connection, referring to shown in Fig. 1 to Fig. 3.
The blower of the present embodiment is centrifugal blower, is 1 delivery air of air hose.The air outlet of blower 2 blows out high-speed flow, warp
The air inlet of top air duct one end 1-4 enters top air duct 1-4, and air-flow circulates along top air duct 1-4 length direction, and flows to
Lower part air duct 1-5 flow to bottom duct air outlet 1-3 through lower part air duct 1-5, then blows out downwards through air outlet 1-3, forms gas
Curtain avoids fumes escaping.Due to the inertia of gas flowing, there is the air-flow close to top air duct 1-4 air inlet in air outlet 1-3
Speed is small, and the air velocity far from top air duct 1-4 air inlet is big；There are apparent velocity gradients for the air-flow of air outlet 1-3；For
Solution this problem keeps the air-flow of air outlet 1-3 blowout uniform, and the present embodiment is formed with S-shaped air duct, S inside air hose 1
Shape air duct includes top air duct 1-4 and lower part air duct 1-5, and top air duct 1-4 area is greater than the area of lower part air duct 1-5；On
Portion air duct 1-4 is the primary flow path of air-flow, and lower part air duct 1-5 is connected to air outlet 1-3；Using S-shaped air duct, top air duct 1-4 can be made
Interior gas, which flows between air outlet 1-3, longer distribution, diffusion length, when air outlet 1-3 speed is uneven, will lead to wind
The resistance of each position is not also identical in road, at this point, air-flow can be redistributed in elongated air duct, original high-speed flow by
Speed is reduced greatly in resistance, low speed flow originally improves speed since resistance is small, so that air outlet 1-3's goes out wind velocity
Uniformly, i.e., mean air flow flow velocity is played the role of in S-shaped air duct.Therefore, the air curtain structure of the present embodiment, blower delivery air to S
Shape air duct is blown out through air outlet 1-3, forms out the uniform gas curtain of wind velocity, solves that air outlet 1-3 wind speed is non-uniform to ask
Topic, so that outlet air is uniform at air outlet 1-3；Moreover, structure is simple, compact, easy to process, cost is relatively low.
Due to top air duct 1-4 air inlet high-speed flow effect of inertia, although so that air-flow is made by the stream in S-shaped air duct
With apparent skewness being still had into the air-flow before air outlet 13, especially close to top air duct 1-4 air inlet
The air velocity of position, top air duct 1-4 is maximum, the deflection most serious of air-flow, and the skewness of air-flow makes finally from out
The air-flow of air port 1-3 blowout can not vertically downward, meanwhile, by ready-made vortex below deflection air-flow, stop deflection wind underside
The air-flow of part air outlet 1-3 flows out, this will make in the air outlet 1-3 gas velocity close to top air duct 1-4 air inlet position
Spend it is less than normal so that air outlet 1-3 outlet air is uneven.In order to solve the unevenness of air outlet 1-3 outlet air caused by skewness, in lower part
Being laid staggeredly in the 1-5 of air duct along lower part air duct length direction (namely duct length direction) has multiple long water conservancy diversion chaste tree 1-6 and more
A short-range missile stream chaste tree 1-7, it is shown in Figure 4, so that air-flow being capable of the side of being adjusted after too long water conservancy diversion chaste tree 1-6, short-range missile stream chaste tree 1-7
To, improve air-flow skewness, the final air-flow for blowing out air outlet 1-3 can vertically downward, meanwhile, close to top air duct 1-4 into
The air outlet 1-3 air velocity of tuyere position is also obviously improved.Long water conservancy diversion chaste tree 1-6 and short-range missile stream chaste tree 1-7 are alternately arranged, be in order to
So that air-flow is from being transition step by step top air duct 1-4 to air outlet 1-3, space is gradually become smaller, and distribution of air flow is more uniform,
Equal length water conservancy diversion chaste tree is avoided to shunt uneven situation.Therefore, by alternately laying long water conservancy diversion chaste tree 1-6 and short-range missile stream chaste tree 1-7, so that
Air-flow can blowout air outlet 1-3 more evenly.
In order to overcome the inertia force of high-velocity fluid, keep the outlet air of air outlet 1-3 more uniform, the edge in the 1-4 of top air duct
Top air duct length direction (namely duct length direction) be laid with multiple baffles, such as baffle 1-8 and baffle 1-9, referring to figure
4, shown in Fig. 5.Due to the setting of baffle, so that air-flow is offset up at baffle, air-flow passes through the position (position locating for baffle
Set) resistance increase, air-flows more in this way will flow to the relatively small region of resistance, and the region is precisely close to top wind
The air outlet 1-3(of road 1-4 air inlet can be described as proximal end air outlet 1-3) locating for region, the air-flow stream in the region can be increased
Speed reaches the uniform purpose of air outlet 1-3 wind speed.
In order to avoid setting baffle makes air duct internal resistance increase too big, therefore, ventilation hole is offered on baffle, formed
Orifice plate, fraction can be flowed through by ventilation hole, reduce the resistance of baffle.For example, opening up ventilation hole 1-8- on baffle 1-8
1, ventilation hole 1-9-1 is opened up on baffle 1-9.
In the present embodiment, there are two the baffle is laid, such as baffle 1-8 and baffle 1-9, wherein baffle 1-9 is laid
In the position close to top air inlet of air duct, baffle 1-8 is laid in the middle position in top air duct, both further reaches air outlet
The uniform purpose of 1-3 outlet air, and baffle laying is avoided excessively to cause air duct internal resistance excessive.
Since air-flow enters air duct from the air inlet of top air duct one end 1-4, this meeting close to top air duct 1-4 so that enter the wind
The air outlet 1-3(of mouthful position can be described as proximal end air outlet 1-3) air velocity it is smaller, far from top air duct 1-4 air inlet position
The air outlet 1-3(set can be described as distal end air outlet 1-3) air velocity it is larger, it is uneven that this also leads to wind speed, therefore,
The big outlet air region of air velocity reduces the width of air outlet 1-3, increases the resistance of the position, so that air velocity reduces；?
The small outlet air region of air velocity increases air outlet 1-3 width, reduces the resistance of the position, so that air velocity increases, thus
Reach the uniform purpose of speed.Therefore, in order to which the outlet air for further increasing air outlet 1-3 is uniform, bottom duct air outlet 1-3 from
Close to one end of top air inlet of air duct to one end of separate top air inlet of air duct, width is gradually reduced.That is, close to top wind
The width of the air outlet 1-3 of road air inlet be d1, far from top air inlet of air duct air outlet 1-3 width be d2, d1 > d2,
It is gradually reduced by d1 to d2, it is shown in Figure 6.
