Description
Technical field
The invention belongs to pesticide spray technical fields, and in particular to a kind of pneumatic atomization static nozzle and spraying system.
Background technology
Problem existing for current industry：Static nozzle is mainly based on pressure atomization, inductive charging.Wherein, 1) exist
The mist droplet particle size of pressure atomization is about 100-300 microns under 0.3MPa, it is difficult to is atomized as smaller droplet, and smaller droplet helps
In induction type charged process.2) plug-in method is to make the most direct effective method of liquid electrification, but plug-in method makes entirely
Spraying system, or even entire spraying machine all charge.This requires spraying systems to have good insulating properties, just in case there is peace in electric leakage
Full hidden danger.
Invention content
The technical problem to be solved by the present invention is to provide a kind of pneumatic atomization electrostatic in view of the above shortcomings of the prior art
Nozzle and spraying system, it is simple in structure, it is reliable and stable, compared with traditional low speed flow auxiliary transports, substantially reduce lotus
The transport time of electric droplet improves liquid deposition effect.
To realize the above-mentioned technical purpose, the technical solution that the present invention takes is：
A kind of pneumatic atomization static nozzle and spraying system, wherein：Including air compressor machine, gas jet mouth, metal mesh, electrode
Seat, electrode, the first bronze medal needle, the second bronze medal needle, high voltage power supply, pump, spray tank, inlet tube and promotion medicine-chest, the air compressor machine are logical
It crosses pipeline to connect with the air inlet on gas jet mouth top, the inlet tube is mounted in the oblique mounting hole on gas jet mouth
And inlet tube is connect by pipeline with medicine-chest outlet at bottom is promoted, the promotion medicine-chest top is connected by pipeline and pump, institute
The pump stated is connect by pipeline with the outlet of spray tank bottom, and the electrode tip holder is fixedly mounted in the portion of gas jet gonys
In heart hole, the electrode be mounted on electrode tip holder on, the first bronze medal needle be mounted on electrode tip holder on mounting hole in and first
Copper Aculeata is connect with electrode, and in the mounting hole that the second bronze medal needle is mounted on gas jet mouth and the second bronze medal needle passes through electricity
In through-hole in electrode seat, the metal mesh is mounted in electrode tip holder centre bore and metal mesh is connect with the second bronze medal Aculeata, institute
The high voltage power supply both ends stated all are connect with the first bronze medal needle and the second bronze medal needle by conducting wire respectively.
To optimize above-mentioned technical proposal, the concrete measure taken further includes：
In above-mentioned gas jet mouth centre bore la farr pipe is equipped with close to medium position.
The mesh number of above-mentioned metal mesh is 16~20 mesh.
Above-mentioned inlet tube left end inlet is less than 5mm apart from la farr pipe exit L.
La farr pipe minimum cross-sectional area and discharge area ratio are between 1.15~1.45 in above-mentioned gas jet mouth.
The present invention uses air compressor machine or roots blower for air supply source, because spraying system pipeline is complicated, it is desirable that air source has
High pressure characteristics (for opposite wind turbine).
Operation principle of the present invention：After high pressure draught enters gas nozzle, accelerate under la farr pipe effect, after compression,
Suction chamber forms negative pressure.Under atmospheric pressure effect, liquid enters gas nozzle from medicine-chest is promoted.Into the liquid after nozzle in height
Under fast airflow function, it is atomized as after droplet, mist droplet deposition is on metal mesh.And metal mesh is connect with high voltage power supply, by metal
It is sprayed after the droplet direct charging of net, in exit, induction electrode is installed, charged droplets are further charged under electrode effect.
Wherein, metal mesh mesh number contributes to more greatly droplet charged, but increases gas-flow resistance.To make inlet more satisfactory
Negative pressuren zone, it is proposed that inlet apart from la farr pipe exit L be less than 5mm.To make gas nozzle generate bigger in suction chamber
Negative pressure, it is proposed that la farr pipe minimum cross-sectional area and discharge area ratio are between 1.15~1.45.If belonging to ultra low volume spray,
Suction line can be directly connected with sprayer medicine case, the negative pressure for relying only on gas nozzle generation takes feed flow, can delete in the system
Promotion medicine-chest, the accessories such as pump.
After uncharged liquid is atomized into droplet by the present invention using high-speed flow, plugged on metal mesh, due to
Drop belongs to discrete state and by high speed airflow influence, and electric current will not enter spraying system with droplet, therefore there is no safety
Hidden danger, and the droplet for not filling electricity with carries out inductive charging by electrode, ensures charged effect.
The advantage of the invention is that the following：Being formed by droplet has the carrying capacity of bigger, reliable and stable and structure
Simply；Compared with traditional low speed flow auxiliary transports, the transport time of charged droplets is substantially reduced, improves liquid deposition effect
Fruit.
