Description
The utility model relates to the facility field of electrostatic spray large tracts of land operation.
According to the interrelated data record, the electrostatic spray technology is to grow up the fifties.It is an applying high voltage static, by different charging modes, forms a high-voltage electrostatic field between shower nozzle and target.Soup is filled with electric charge when shower nozzle atomizes, forms charged soup droplet group.Under the effect of electrostatic field force and other external force, droplet is adsorbed on the target do directed movement, improves the sedimentation rate of droplet group on target, thereby improves prevention effect, and soup etc. is saved in pollution abatement.
Learn that according to DIALOG international on-line retrieval system and manual information retrieval relevant electrostatic spray Study on Technology still is in experimental study at present and progressively moves towards the application stage both at home and abroad, it is used also just based on small-sized electrostatic sprayer.As the U.S. famous electrostatic spray authority Law professor,,, do not see relevant electrostatic sprayer product Report as the reported in literature among ASAE and the IEEE though carry out shower nozzle test and indoor electrostatic spray performance study morely; Some scholars of West Germany and Britain also just carry out the application study of indoor performance research and small-sized electrostatic sprayer product, as the reported in literature among AMA and the J.Agric.Eng.Res.; The U.S. and Canadian scholar once carried out the experimental study of aviation electrostatic spray respectively, as the reported in literature among ASAE and the IEEE, but owing to fuselage reason such as charged and operating condition harshness, only be in the experimental study stage at present, do not see practical application; China south China hotwork institute once developed small-sized, the backpack electrostatic sprayer, and this machine adopts centrifugal blower and contact charging method; Another kind is a Jiangsu Polytechnical College vehicular electrostatic sprayer, and this machine adopts centrifugal blower, and its air velocity decay is very fast, and spraying swath is narrower; The conventional ultra-low-volume sprayer of Xinjiang vehicular that agricultural machinery was also once developed, this machine adopts centrifugal blower, and it sprays to and adopts hydraulic method to regulate the location, but reliability is not enough.More than these types, mostly can only be applicable to small size spraying, can not satisfy the large-scale spraying requirement of numerous urgent needs, and spray to that to regulate security, economy and reliability relatively poor.
The purpose of this utility model provides a kind of electrostatic atomizer that sprays to adjusting reliably that has, the big spraying swath spraying operation that its realizability can be good.
The purpose of this utility model is achieved in that at the axial flow blower right-hand member and connects deflection cone tube and atomizing air duct.Articulate with turnbuckle between these two, gap location is coverd with the rubber that is flexible coupling, and internal and external electrode is equipped with by tripod support fixedly connected gas-liquid twin shower nozzle on the atomizing air duct respectively in two central authorities on tripod support and atomizing air duct.
Advantage of the present utility model is: deflection cone tube of adorning on axial flow blower and atomizing air duct articulate with turnbuckle, thereby can reliably freely realize spraying to adjusting.Owing to gas-liquid twin shower nozzle is fixedly connected on central authorities between two with the tripod support on the atomizing air duct, therefore when the atomizing air duct sprayed to change, the shower nozzle outlet remained on the blower fan axial line.Again owing on tripod support and atomizing air duct, internal and external electrode is housed respectively, so after adding electrostatic pressure, just can realize corona charging, make the droplet after shower nozzle atomizes fill negative electrical charge with, droplet flies to target under the air-flow effect, satisfactorily finish big spraying swath operation, such sprayer unit, the mist spectrum is narrow, the productivity ratio height, can spray 4000～5000 mu every day, its prevention effect improves more than 20% than non-electrostatic spray.Cost is low, compares with the aviation locust of going out, and the mu cost reduces by 45.4%.Because the utility model use standard component and seriation parts are many, so technology is simple, be easy to produce in batches.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
