Description
Technical field
The present invention relates to a kind of electrostatic atomiser, in particular for spraying the electrostatic spraying device of agrochemicals medicine.
Background technology
The principle of electrostatic spray technology is: utilize high-pressure electrostatic to form a high-voltage electrostatic field between shower nozzle and target, soup is filled with electric charge when shower nozzle atomizes, under the effect of electrostatic field force and other external force, droplet is adsorbed on the target do directed movement, thereby improves sedimentation rate and the uniformity of droplet group on target.
When utilization electrostatic spray technology, the particle radius that produces droplet is a very The key factor, and the gravity of the excessive then droplet of radius itself is considerably beyond its suffered electrostatic force, and electrostatic interaction is little, it is unrestrained that the characteristics of motion of droplet remains nature, and major part is received by the earth; The too small then carried charge of radius is little, and the electrostatic force same purpose is very little.
Disclose a kind of axial flow wind spraying aid type electrostatic atomizer in Chinese utility model patent specification 92213012.4, it comprises axial flow blower, high pressure generator, atomizing air duct and between axial flow blower and atomizing air duct and the deflection cone tube that is connected with the two.Effluent air quickens back air inlet of minor air cell in the atomizing air duct through water conservancy diversion wind awl tube and enters the minor air cell in the axial flow blower, thereby the liquid of eddy current indoor high-speed rotation is gone out the nozzle formation droplet of atomizing air duct opening part.The negative pole of high pressure generator is connected with nozzle inner walls, makes negative electricity on the droplet band of ejection.
Yet this electrostatic atomizer that has blower fan, though reached the effect that reduces the droplet radius, but because the influence of blower fan wind-force, can make droplet have bigger initial velocity, make droplet elongated with the The interaction distance of air in unrestrained process, thereby its institute electrically chargedly almost all neutralizes by air, and the electrostatic technique effect of spraying is little.
Owing on handle portion conduction or insulation, drainage tube, can form high-pressure electrostatic, make the high pressure output negative pole reduce, so the electrostatic effect of spray film be poor to the effect that soup discharges negative electrical charge because of the Kelvin effect stored charge.
Summary of the invention
The object of the present invention is to provide a kind of electrostatic atomiser, it can reduce or eliminate the static on handle and the drainage tube, improves the charging effect of droplet.
Technical scheme of the present invention is: a kind of electrostatic atomiser, comprise HV generator with high pressure output negative pole, liquid storage container, drainage tube, atomising device, one end of described drainage tube is connected with described liquid storage container and the other end is received on the atomising device, described atomising device comprises the shower nozzle motor, rotating disk, the machine shaft of described shower nozzle motor is connected with described rotating disk, the high pressure output negative pole of described HV generator is positioned at the drainage tube port of export of described drainage tube, the power supply lead wire of described HV generator is connected on one first dc source, the positive source and the null electrode of described first dc source are electrically connected, and described null electrode is used for contacting with the human body of operation of electrostatic sprayer unit.
The power supply lead wire of described shower nozzle motor is connected on another independently on second dc source.
Have handle on the described drainage tube, described null electrode is positioned on the described handle.
The invention has the beneficial effects as follows: be electrically connected with described null electrode because the input of HV generator is anodal, null electrode contacts with operating personnel in operating process, operating personnel are equivalent to zero potential, make the electric charge that gathers on handle and the drainage tube surface to obtain discharging, thereby improve droplet static electrification effect effectively by human body.
