Description
Technical field
The invention belongs to Centrifugal Electrostatic atomization technique field more particularly to a kind of Centrifugal Electrostatic atomising devices.
Background technique
Centrifugal Electrostatic atomization technique can be widely used for planting industry, animal husbandry, aquaculture, forestry, the industries such as air cleaning and
Place.Centrifugal Electrostatic atomizer is to rotate generated centrifugal force using liquid at high speed to atomize the liquid into, and use high pressure
Electrostatic generator makes the droplet of atomization with electrostatic charge.Droplet with electrostatic charge is in electric field force, gravity and aerodynamic
It under effect, does directed movement and is adsorbed on each position of target, there is deposition efficiency height, droplet drift to scatter and disappear less, adhesive force
The superperformances such as strong.
Traditional pesticide application technique remains on large capacity and big droplet spray technique level.It is sprayed when plant protection operation
Medical fluid fall to the ground in the movement of falling object, due to being influenced by wind-force and gravity, it is attached that the pesticide of sprinkling only has small part
Plant hat surface on, most medical fluids can trickle or be scattering on ground, and pesticide utilization rate is low, and environmental pollution is serious.
When fountain height is more than certain limit, the fine mist on blade can be condensed into big droplet and tumble, be lost, and make on blade instead
The pesticide volume of attachment drastically reduces；Especially it is difficult to touch drug, plant surface at the back side of plant concealment part and blade
The medical fluid of face spray deposition is extremely difficult to ideal effect, cannot effectively kill germ cordyceps sinensis.And it is formed by electrostatic Spraying technique
Droplet have a large amount of electrostatic charges, to target generation outflank effect.Charged Droplet is under the action of electrostatic field force and other external force
It doing directed movement and is adsorbed on each position of plant, reach few using medical fluid, it is few that deposition efficiency is high, droplet drift is scattered and disappeared,
Pesticide utilization rate can be increased to 90% or more, to reduce pesticide environmental pollution.Existing static nozzle all makes
With pressure nozzle, when atomization, needs the water pump assisted or air pump to greatly improve fluid pressure, so the device is complicated, energy consumption is high,
And in the actual operation process, spray head is frequently occluded, and influences working efficiency.On the other hand, rotary disk type sprinkler head (as shown in Figure 1)
Or centrifugal sprinkler is to realize liquid atomization by the high speed rotation of liquid, does not need the auxiliary of water pump or air pump, structure is simple,
It is light-weight, spray head blocking is not had and is occurred, and is very suitable to the plant protection operation of small and medium size unmanned aerial vehicles, but existing turntable or centrifugation
Formula spray head, is only capable of atomized liquid, and liquid can not be made with electrostatic charge, therefore does not have the advantages of electrostatic Spraying technique；Fig. 1
Shown in, for rotary disk type sprinkler head due to there was only one layer of orifice, atomization quantity is limited, and the wind generated when high speed rotation is made an uproar greatly；With
The charged spray head of discharge mode installs static discharge tip additional every empty a distance in nozzle exterior, and the droplet formed by spraying is passing through
Partial electrostatic lotus can be carried after region of discharge, this mode is usually charged unevenly, can not be sufficiently charged for droplet, Er Qie
Ozone, the pernicious gases such as oxides of nitrogen gas can be generated in discharge process.
