Detailed description of the invention
Two wind of the present embodiment send orchard electrostatic sprayer complete machine structure as depicted in figs. 1 and 2, the two groups of radial symmetric comprising five one group are placed in the centrifugal airduct 3 of ring support the right and left, be parallel to each other with the centrifugal airduct of group, in the middle of it, the center of a centrifugal airduct extends through the center of circle of ring support 11 as symmetrical center line.In addition, axial flow blower 12 and centrifugal blower 8 is also comprised.Axial flow blower 12 is positioned at the central side of ring support 11, and its axial flow center overlaps with the center of circle of ring support.The opposite side of ring support 12 is equipped with guides axial flow into centrifugal airduct 3 direction axial flow outer air duct 2 thus the deep bead 13 of formation peripheral air stream.The air outlet of centrifugal blower 8 is communicated with the entrance point of centrifugal airduct 3 respectively by uniform connecting hose 9.Centrifugal blower 8, ring support 11 are all placed in the rear portion on the walking chassis 4 of hitching machinery, the walking chassis 4 of this hitching machinery are also equipped with operation control system 5, engine 6, membrane pump 7 and electrostatic generator 10.
The port of export of the centrifugal airduct 3 of every root all installs the profiling electrode static nozzle 1 of annular air-flow path, and this profiling electrode static nozzle 1 can adopt application number for the profiling electrode static nozzle disclosed in 201420084154.9 Chinese patents.Profiling electrode static nozzle 1 concrete structure of the present embodiment as shown in Figure 3, there is the neck bush 1-3 being inserted into centrifugal airduct 3 port of export, the outer end of this neck bush 1-3 clamps the profiling electrode 1-2 being coated with insulating coating 1-1, this profiling electrode 1-2 be cone angle and hollow cone spray angle match tubaeform, be electrically connected with the quiet generator 10 of high pressure.The inner center of neck bush 1-3 is supported by radial bolt installs cylindrical sprinkler cap 1-4, forms pipe gas channel.The endoporus of this sprinkler cap 1-4 installs the hollow cone atomizing nozzle 1-9(YZ80005 type Suzhou Lan Ao precision plastic rubber Co., Ltd product of outsourcing), the inlet of its inner through nozzle boss 1-5 by woven hose through the pipe joint be fixed on centrifugal airduct 3 sidewall, then with the outlet of the membrane pump 7 as infusion pump.The stage casing of neck bush 1-3 has convergent conical bore section from the inside to the outside, form the conical ring gas channel be communicated with pipe gas channel between this conical bore section with sprinkler cap 1-4 outer end to hollow cone atomizing nozzle 1-9 outer end, thus form the complete annular air-flow path of profiling electrode static nozzle.
During work, as shown in Figure 4, the air-flow that centrifugal blower produces suitable speed at annular air-flow path can make the droplet sprayed through electro-hydrodynamic atomization from spray nozzle enter the L section region before charged region by air-flow secondary-atomizing, forms the taper mist stream of average diameter 65-75 micron.Result, not only make charged successful strengthen further (test shows that charge-mass ratio can reach the 1.3-1.5 of prior art doubly) because uniform particle sizes attenuates, mist flow velocity can be made greatly to improve (test shows that comparable prior art increases 10 times, increases to 10m/s by original 1m/s) simultaneously; After droplet enters the charged region T of profiling electrode, fully responded to electric charge on lotus, then transferred out fast.The air-flow that axial flow blower is finally formed forms the peripheral air stream of charged spray, this peripheral air stream not only can be comparatively stable flow velocity play and charged spray and outside air isolated thus avoids the effect that charged mist flow velocity decays, simultaneously, this isolation also has the effect that air is lost towards periphery of suppression electric charge, effectively control the decay of external environment condition to charged spray, be therefore referred to as " guarding the emperor " air channel.Result, after adopting the present embodiment, still there is when the charged spray of the high charge-mass ratio of maintenance can be made to arrive longer-distance target the speed of certain (about 5m/s), even if branches and leaves are comparatively dense, droplet also can reach canopy depths, and under electric field force effect, deposit to the back side of branches and leaves, thus with higher penetrability and deposition, greatly reduce the drift loss of droplet.
During design, the involutory reason of determination of parameter arranges that to obtain the effect optimized significant.Through the calculating repeatedly to various affecting parameters, test, by rationally arranging structural parameters and centrifugal blower parameter, making the outlet air flow velocity of annular air-flow path be 20-25m/s, preferably 22-23 m/s, desirable droplet secondary-atomizing effect can be obtained.And suitable chosen axis flow fan, the neighboring gas flow mean flow rate that outer air curtain passage can be made to be formed at centrifugal wind tube outlet at air-flow mean flow rate and the annular air-flow path of centrifugal wind tube outlet is equal, the air-flow of axial flow outer air duct can be made like this " to guard the emperor " act on ideal.
More specifically, because the outer face a of sprinkler cap 1-4 is positioned at conical ring gas channel, the region, triangular-section being positioned at conical ring gas channel is defined after being connected with the cylindrical of hollow cone atomizing nozzle 1-9, therefore air-flow is arrived the flaring horn mouth of profiling electrode through conical ring gas channel by pipe gas channel, actual experienced by flow area from large to small---changing from small to big---from large to small, the flaring horn mouth at final arrival profiling electrode place, flow area is expanded rapidly.Experimental study shows, the change that twice, this airflow cross section is descending, ascending again, make the secondary-atomizing air-flow of annular air-flow path have pulsating nature, the desirable droplet being atomized into average diameter 65-75 micron from spray nozzle through the droplet that electro-hydrodynamic atomization sprays can be made.
Result, fully charged droplet is made to deliver in dense canopy in air propels blowing down, with high deposition rate uniform deposition under electric field force effect, especially the liquid deposition effect of canopy depths and blade back is splendid, can realize the low volume of " minimum spray amount obtains best prevention effect ".
Be summed up, the present embodiment has following distinguishing feature:
1. adopt ten groups of profiling static nozzles, charge capacity is strong, and charged electrical forces down.
2. the air-flow of centrifugal blower not only effectively can improve the charged effect of droplet of profiling static nozzle---
A. in pipe, the droplet secondary-atomizing of hydraulic atomization spray nozzle is obtained that to be more carefully beneficial to droplet charged by air-flow further;
B. the droplet that lotus powers on can be transferred out in time, be conducive to new droplet better charged;---and improve the penetrability of charged spray.
3. the air-flow that axial flow blower produces not only effectively prevents from responding to the absorption of electrostatic droplet at airduct outer wall, and effectively electrostatic spray and external environment condition is isolated, and reduces the rate of decay of spray carrying capacity, also contributes to the wind field uniformity of centrifugal blower.
