Description
Technical field
The utility model belongs to pesticide spray technical field, and in particular to a kind of pneumatic atomization static nozzle and spraying system
System.
Background technique
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.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of pneumatic atomization in view of the above shortcomings of the prior art
Static nozzle and spraying system, structure is simple, reliable and stable, compared with traditional low speed flow auxiliary transports, greatly shortens
The transport time of charged droplets improves medical fluid deposition effect.
To realize the above-mentioned technical purpose, the technical solution that the utility model is taken are as follows:
A kind of pneumatic atomization static nozzle and spraying system, in which: 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 is mounted on electrode tip holder, and the first bronze medal needle is mounted in the mounting hole on electrode tip holder 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 pass through conducting wire and connect respectively with the first bronze medal needle and the second bronze medal needle.
To optimize above-mentioned technical proposal, the concrete measure taken further include:
La farr pipe is equipped with close to medium position in above-mentioned gas jet mouth centre bore.
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 utility model uses air compressor machine or roots blower for air supply source, because spraying system pipeline is complicated, it is desirable that gas source
With high pressure characteristics (for opposite blower).
Utility model works principle: after high pressure draught enters gas nozzle, accelerate under la farr pipe effect, compression
Afterwards, negative pressure is formed in suction chamber.Under atmospheric pressure effect, medical fluid enters gas nozzle from medicine-chest is promoted.Into the medicine after nozzle
Liquid is atomized under action of high-speed airflow as after droplet, mist droplet deposition is on metal mesh.And metal mesh is connect with high voltage power supply, warp
It is sprayed after crossing the droplet direct charging of metal mesh, in exit, induction electrode is installed, charged droplets are under electrode effect, into one
It walks charged.
Wherein, it is charged to facilitate more greatly droplet for metal mesh mesh number, but increases gas-flow resistance.To think that inlet in dogmata
Negative pressuren zone, it is proposed that inlet apart from la farr pipe exit L be less than 5mm.To keep gas nozzle bigger in suction chamber generation
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 using high-speed flow by the utility model, plugged on metal mesh,
Since drop belongs to discrete state and by high speed airflow influence, electric current will not enter spraying system with droplet, therefore be not present
Security risk, and the droplet for not filling electricity with carries out inductive charging by electrode, guarantees charged effect.
The utility model has the advantage of the followings: be formed by droplet with bigger carrying capacity, it is reliable and stable and
Structure is simple；Compared with traditional low speed flow auxiliary transports, the transport time of charged droplets is substantially reduced, it is heavy to improve medical fluid
Product effect.
