Abstract
The electrostatic sprayer includes a high voltage electrostatic generator with high voltage output negative pole, a liquid storing container, a drainage tube, and an atomizer. The drainage tube is connected between the liquid storing container and the atomizer; the atomizer includes a motor and a turntable connected to the rotation shaft of the motor; the high voltage electrostatic generator has high voltage output negative pole located in the outlet of the drainage tube and power line connected to the first independent DC power source; and the motor in the atomizer is connected to the second independent DC power source. Owing to the independent DC power sources, the movement of the motor in the atomizer will not affect the generation of electrostatic generator, and this result in more charges in the high voltage output negative pole and high electrostatic effect for spraying.
Description
Technical field
The present invention relates to a kind of electrostatic atomizer, in particular for spraying the electrostatic atomizer 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.
In addition, designed before this electrostatic atomizer, generally comprise two kinds of power devices of shower nozzle motor and high pressure generator, and these the two kinds shared power supplys of device, charged drop can be by the anodal attraction of the motor of close together after ejection like this, cause suck-back, make droplet effectively to be deposited on the target crops.
Summary of the invention
The object of the present invention is to provide a kind of a kind of electrostatic atomizer that can avoid the suck-back phenomenon to occur, improve the sedimentation rate of droplet group on target.
Technical scheme of the present invention is: a kind of electrostatic atomizer comprises HV generator, liquid storage container, drainage tube, atomising device with high pressure output negative pole.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 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 port of export of described drainage tube, the power supply lead wire of described HV generator is connected on one independently on first dc source, and the power supply lead wire of described shower nozzle motor is connected on another independently on second dc source.
The positive source and the null electrode of described first dc source are electrically connected, and when described HV generator and described shower nozzle motor all obtained two groups of DC power supplies respectively, described null electrode was connected with the human body of operation of electrostatic sprayer unit.
The invention has the beneficial effects as follows: because high pressure generator has adopted independently power supply, therefore the positive source of shower nozzle motor and power cathode can not produce electrostatic influence to the moving process of droplet, can be so that soup electrically charged amount in through the high pressure output negative pole be more, the electrostatic effect during sprinkling is better.
