Detailed description of the invention
The electrostatic spinning nozzle of trapezoidal periodic array as depicted in figs. 1 and 2, including nozzle body 3, this nozzle body 3
There is a liquid outlet channel in inside, for being imported by outside spinning liquid.It addition, have in nozzle body 3 output plane with
And this nozzle body 3 is provided with the export structure of at least two groups, described export structure is for collecting and will enter from liquid outlet channel
The spinning liquid entered sprays with spinning.
In embodiment, often group export structure all includes be opened on output plane four spray orifices and is connected to spray
Needle nozzle 4 on hole, as spray orifice not carried out label in accompanying drawing, but it should be understood readily by those skilled in this art, spray orifice
It is overlapping with needle nozzle 4.These pin type spray groups 4 are metallic nozzle and are needle point at it away from the end of spray orifice, this kind
Needle nozzle 4 is nozzle structure commonly used in the art, is not explained in detail at this.Often organize the needle nozzle 4 of export structure all
It is contour, and, each needle nozzle of different group export structures is also contour, namely all of needle nozzle 4 is the most relative
For output plane contour.
Above-mentioned four spray orifices often organizing export structure lay respectively on a trapezoidal summit, namely successively by adjacent two
After individual spray orifice line, the track of line can constitute one trapezoidal.Two or more sets above-mentioned export structures are along the length of nozzle body 3
Degree direction linear array is arranged, thus each trapezoidal bottom is the most in a straight line.By closest in adjacent sets export structure
After adjacent two spray orifices (the two spray orifice is simultaneously on bottom) line, this line trapezoidal is connected in series each, thus
The line making all adjacent orifices constitutes a trapezoidal wave track.
After the track of each spray orifice line defines above-mentioned trapezoidal wave track, each needle nozzle electric field can be greatly reduced
Influence each other, and improve the electric field intensity that needle nozzle is most advanced and sophisticated.
It is further preferred that it is equal often to organize the spacing of adjacent orifices in export structure, namely four spray orifices lay respectively at one
On four summits of isosceles trapezoid, and the waist of this isosceles trapezoid and shorter upper base length equal.
On the basis of above-mentioned isosceles trapezoid, in adjacent sets export structure closest to adjacent two spray orifices spacing with etc.
The trapezoidal waist length of waist is also equal, namely each adjacent orifices spacing constituting trapezoidal wave track is equal, in trapezoidal wave track two
The adjacent spacing between summit is equal.This equally spaced structure is more beneficial for reducing influencing each other and improving pin of electric field
The electric field intensity of formula nozzle tip.
Below by way of Electric Field Simulation, the present embodiment is contrasted with traditional sprinkler heads matrix arrangement.
Simulation parameter is as follows: needle nozzle diameter 0.5mm, a length of 15mm, and adjacent nozzle spacing is 20mm, and material is not
Rust steel, needle nozzle number is 16.Electrostatic spinning nozzle from and not shown collection device distance be 100mm, collection device width
For 100mm, a length of 200mm, thickness is 2mm, and material is aluminum.Simulation software is comsol, and emulation voltage is 50kV；Institute's power taking field is equal
For electric field at nozzle tip 1mm.
The nozzle 41 of contrast simulation becomes double arranged in linear arrays, as shown in Figure 4.Nozzle diameter 0.5mm, a length of
15mm, adjacent nozzle spacing is 20mm, and material is rustless steel, and nozzle number is 16.Install nozzle 41 electrostatic spinning nozzle from
And not shown collection device distance is 100mm, a width of 100mm of collection device, a length of 200mm, thickness is 2mm, and material is aluminum.Imitative
True software is comsol, and emulation voltage is 50kV；Institute's power taking field is electric field at nozzle tip 1mm.
It is illustrated in figure 5 the electrostatic spinning nozzle Electric Field Simulation result of trapezoidal periodic array and the electrostatic spinning of double array
Shower nozzle Electric Field Simulation Comparative result, as shown in Figure 5, the nozzle emulation maximum field of the trapezoidal periodic array of the present embodiment is 4.7
×106V/m, and the nozzle of double array emulation maximum field is 4.5 × 106V/m；Meanwhile, the nozzle emulation of trapezoidal periodic array
Field minimum is 4.0 × 106V/m, and the nozzle of double array emulation field minimum is 3.5 × 106V/m, it can be seen that trapezoidal week
The nozzle Electric Field Simulation numerical value major part of phase array is greater than the nozzle simulation numerical of double array, therefore, trapezoidal cycle battle array
Between the electrostatic spinning nozzle of row, electric field interferes with each other and compares electric field between double linear array electrostatic spinning nozzle and be concerned with mutually
Disturb smaller, and as can be known from Fig. 5, imitating of No. 4 nozzle of the electrostatic spinning nozzle of trapezoidal periodic array to No. 13 nozzle
The diversity of true electric field is little, and the poorest 0.1 × 106V/m, the shower nozzle electric field therefore having 62.5% is that ratio is more uniform, and double
The Electric Field Numerical of jet array shower nozzle only No. 7 nozzles relatively are to 4, No. 10 nozzles, and the Electric Field Numerical of all nozzles is poor
Different relatively big, the unfavorable condition such as spinning can be caused uneven.Therefore, the electrostatic spinning nozzle of trapezoidal periodic array is particularly suited for battle array
Row nozzle spinning.
It addition, Fig. 3 is a kind of electrostatic spinning apparatus using above-mentioned electrostatic means shower nozzle, it is provided with in nozzle body 3
Inlet, inlet is by the liquid outlet channel connection spray orifice in nozzle body 3, and inlet is circumscribed with conduit 2 and liquor box 1.
The above be this utility model preferred embodiment, it is not intended that this utility model protection domain
Limit.
