Abstract
An electrostatic sprayer for spraying the atomized chemical liquid onto the leaves of agricultural crops is composed of a high-voltage static electricity generator, chemical liquid container, flow guide tube, and atomizer consisting of motor and rotary disc. The chemical liquid is atomized by said atomizer and then by the like electric charges repelling one another between electrified liquid drops, resulting in superfine liquid drops.
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 between shower nozzle and target, to form a high-voltage electrostatic field, 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 the sedimentation rate of droplet group on target.
When utilization electrostatic spray technology, the particle diameter that produces droplet is a very The key factor, and the gravity of the excessive then droplet of particle diameter own is considerably beyond electrostatic force, and electrostatic interaction is little, and it is unrestrained that the movement locus of its droplet remains nature, and major part is received by the earth; The too small then carried charge of particle diameter is little, and the static 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 the deflection cone 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 that atomizing air duct opening goes out.The negative pole of high pressure generator is electrically 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 mist droplet particle size, 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 effect of the electrostatic technique of spraying is little.
Summary of the invention
The object of the present invention is to provide a kind of energy to produce the electrostatic atomizer of the droplet of suitably big small particle diameter, thereby the electrostatic spray technology is better played effectiveness, improve the sedimentation rate of droplet group on target.
Technical scheme of the present invention is: a kind of electrostatic atomizer, comprise high-voltage electrostatic generator, liquid storage container, drainage tube, aerosol generating means with anodal and negative pole, described drainage tube is connected with described liquid storage container, described aerosol generating means comprises motor, rotating disk, the output shaft of described motor is in transmission connection mutually with described rotating disk, and the negative pole of described high-voltage electrostatic generator is positioned at the port of export of described drainage tube.
Described aerosol generating means also comprises aerosol generating means shell, and the stationary part of described motor is fixed on the described aerosol generating means shell, and the port of export of described drainage tube is fixed on the described aerosol generating means shell.
