Cheng Junliu chambers 15.
Multiple holes plate 2 is formed using stainless sheet steel punching processing, in working region（See attached drawing 4,5）It is placed with according to technique
And the aperture changed, the aperture of aperture and arrangement position change because design is different, so that percent opening is variable.Equalizing lattice 5,
Equal wind net 10, protection network 11 are the stainless steel wire mesh grids of industrialized production, using different string diameter and weaving manner, can be drawn
The change of resistance and percent opening is played, the string diameter of equal wind net 10 is less than the string diameter of equal wind net 5.Multiple holes plate 2 and equalizing lattice 5 are installed on down
On flange 4, the thickness variable, and then the size of regulating static chamber 14 according to demand of lower flange 4.
Referring to attached drawing 6, the face contacted with elastic sealing strip 1 of multiple holes plate 2, by the higher air pressure from inlet air side
Power, air is in the aperture of multiple holes plate 2 at a high speed by the way that due to using relatively thin steel plate punched, resistance is smaller, and air passes through aperture
It is different into 14 rear direction of static pressure chamber, in mixed and disorderly state, and it is rapidly dispersed into static pressure chamber 14 everywhere.Due to installed in lower flange
5 percent opening of equalizing lattice of 4 opposite sides is less than multiple holes plate 2, so air runs into the wire being subject to after equalizing lattice 5 on equalizing lattice 5
Resistance so that the air side wind speed of equalizing lattice reduces, i.e. there are different pressure, multiple holes in the front side of equalizing lattice and the air of rear side
The air of 2 rear side elevated pressures of plate constantly enters plenum chamber 14 from aperture, and equalizing lattice 5 limits the flowing of air, in static pressure
Air in room 14 has the pressure lower than the rear side of multiple holes plate 2, but is pushed the air through more than the pressure of the front side of equalizing lattice 5, pressure
The hole left during the metal wire knitted of equal wind net 5 travels forward, and the pressure in plenum chamber 14 is uniform, and pressure is multiple holes
The difference of the air pressure of the rear side of plate 2 and the resistance of equalizing lattice 5., can be according to specific when producing the filament of different specifications
Need to select the percent opening of suitable multiple holes plate and the percent opening and string diameter of equalizing lattice, so that accurately determine pressure difference, and
To preferably go out wind velocity.In 5 installation process of equalizing lattice, answer it is smooth be stretched on lower flange, and then make the pressure on rear side of equalizing lattice
The amount of overcoming is uniform, and when air is by the equalizing lattice of smooth tensioning, equalizing lattice is identical along the longitudinal direction, institute to the resistance of air
Substantially to obtain uniform wind speed in the front portion of equalizing lattice 5.In theory, even if the quenching system of oversize, passes through
The fairing rectification of the utility model can obtain identical wind speed on whole efforts face.
Bear the wind pressure on whole working face at work due to equal wind net 5, the trend for having deformation warpage, wire is born
Pulling force caused by tension force, so the utility model devises a tensioning flange 6 on front side of equal wind net, and will by bolt 7
It is fixed on lower flange 4, and the surrounding of so whole wind net, which is opened into flange 6, to be pushed down, it is impossible to movement is produced, bolt 7
Pretightning force makes tensioning flange 6 produce stiction with equal wind net 5 to resist the pulling force of the effect of wind pressure generation on the metal filament, from
And ensure equal wind net and be constantly in straight tensioning state.
Referring to attached drawing 7~9, the air-flow blown out from the air side of equal wind net 5, which enters, flows chamber 15, flows chamber 15 and honeycomb is whole
Each honeycomb hole of flowing plate 9 communicates, and making air-flow, equal wind is assigned in each honeycomb hole again, and the size for flowing chamber 15 passes through tensioning
The thickness of flange 6 is adjusted
Honeycomb cowling panel 9 be blowing fairing in another vital part, the honeycomb hole thereon with some regular hexagons,
The center line of honeycomb hole is parallel to each other, and is horizontally disposed with along the longitudinal direction.By the air of equal wind net 5, there is identical flow velocity,
Influenced by 5 braided metal silk of equalizing lattice, there is subtle difference in the flow direction of air, and when flow direction, different air enters
After in the honeycomb hole of honeycomb cowling panel 9, flowed along honeycomb hole, air-flow direction will be run into when different from the axis of honeycomb hole
The side of hexagon, so that the change in direction occur, after being varied multiple times, the flow direction of air will become in the axis of honeycomb hole
In consistent, you can realize straight flowing.Measured by calculating with real data, multiple impacts are until the convergent distance in direction and six
The length of side of side shape has relation, substantially 10~20 times of the length of side.And analysis is found, the smaller length of side, convergent hole length
About short, draw ratio considers the complexity and processing cost of current processing technology to 10 convergences, selects the length of side to be in the present embodiment
The honeycomb hole of 2mm.
Honeycomb cowling panel 9 is with welding fabrication after light sheet bending, in microstructure there are materials to save, constitutionally stable spy
Point.The outlet air surface of honeycomb cowling panel 9 should keep smooth, and shape is neat.The outer edge honeycomb frame 8 of honeycomb cowling panel 9 wraps up,
And apply in certain fastening, the interference from edge can be avoided, prevents destruction of the lateral impact to honeycomb cowling panel 9, and
Ensure 9 hexagonal shape of honeycomb cowling panel stabilization and axis it is straight.
By the air of 9 rectification of honeycomb cowling panel, consistent flow direction is obtained, but longer hole is to flowing through wherein
Air produce resistance, cause the speed air flow close to hexagonal hole heart position to be greater than the sky close to hexagon side position
Flow of air speed.That is on direction of the six deformation hole hearts to hole edge, air flow generates the gradient in speed.For this
In the installed in front line footpath very thin equal wind net 10 of honeycomb cowling panel 9, the percent opening of equal wind net 10 is less than the perforate of equalizing lattice 5
Rate, so wind net 10 has interfered the free flow of air to the resistance of the air for having velocity gradient by honeycomb cowling panel 9
It is dynamic, its speed is reached unanimity, by the later air of equal wind net 10, be provided with basically identical flow velocity again.
Protection network 11 is placed with the outside of equal wind net 10, equal wind net 10 is fixed on honeycomb frame 8 with the mode of spot welding,
And protection network 11 is thrown the net, backplate 12 is compressed fits together with equal wind net 10.Rivet 13 through backplate 12 of throwing the net will throw the net shield
Plate links together with honeycomb frame 8, and the prestressing force of rivet provides thrust for backplate 13 of throwing the net, when equal wind net 10 and protection network
When being subject to the pressure or ambient pressure of air, the pulling force produced in the string diameter of mesh grid will rub the quiet of net with backplate 12 of throwing the net
Wipe power to cancel out each other, so as to ensure the straight tensioning of wire side.
All of the above component combines, collective effect, realizes different sizes, especially up and down size compared with
The demand that wind speed in big cross air blasting blowing commutation system is uniform, wind direction is consistent.Replace the multiple holes plate of different designs and press
Net, can produce suitable wind speed and direction in whole working region rapidly.And the utility model has the advantages of simple structure, web plate is replaced
Use environment that is convenient, being adapted to technological requirement often to change.The mesh grid of industrialized production, it is of low cost easy to purchase.
The operation principle of the utility model is：Fairing is more than the percent opening of equalizing lattice by multiple holes packing free ratio, multiple
Lower flange between orifice plate and equalizing lattice can form the static pressure chamber of different volumes by replacing different thickness.There is the sky of pressure
Gas is entered after static pressure cavity by multiple holes plate aperture is full of static pressure chamber by equalizing lattice resistance, and the static pressure chamber of big volume reduces sky
The flowing velocity of gas, and certain pressure is kept in static pressure chamber, on pressure effect equalizing lattice, pass air through on equalizing lattice
Mesh outflow, the braided steel wire of equalizing lattice produces the air of flowing resistance, air pressure and equalizing lattice steel in static pressure chamber
The resistance one of silk works, and determines the speed by equalizing lattice mesh.The sky for making to overflow from mesh from straight tensioning equalizing lattice
Gas has approximate initial velocity and direction；Static pressure chamber internal pressure equilibrium is identical, passes through equalizing lattice net on any length direction
The air in hole has approximate speed and direction.Solves the problems, such as the wind speed in longer blowing height.When the air of identical speed
Into after honeycomb cowling panel, carry out water conservancy diversion to the air of low speed, no matter air-flow direction how many difference, pass through honeycomb hole
Afterwards, the consistent air flow in direction is obtained substantially.But air pass through regular hexagon hole after, although it is consistent to obtain wind direction
Air flow, but regular hexagon hole wall position and hole heart position can produce speed difference, in order to reduce this species diversity, in honeycomb
The outlet air one side of frame is disposed with the equal wind net of string diameter very little, and equal wind net plays the role of uniform wind speed, reduces regular hexagon hole
Side and the otherness of mesoporous heart position wind speed, but the net tension force of small string diameter is smaller, is easily broken damage, so in outer layer again
Place the net that the larger mesh number in a layer line footpath is 20-50 mesh and play protective action, which is welded on honeycomb frame, protection network
Equal wind net surface is pressed on by backplate of throwing the net, backplate of throwing the net by rivet on honeycomb frame, when equal wind net and protection network
