Description
Technical field
The invention belongs to a plant protecting chemical spraying device, especially a kind of effervescent atomization dispenser shower nozzle.
Background technology
Shower nozzle is the key components of plant protection dispenser facility, directly influences the pesticide supplying effect of facility.At present, widely used pressure atomization shower nozzle and pneumatic atomizer rely on bigger relative speed difference between atomizing medium and the liquid, and the viscosity that mainly overcomes liquid makes the atomization of liquid, and required atomizing pressure is bigger, and viscosity is not easy atomizing more greatly more.As the kinetic energy soup that atomizes, simple in structure, cost is lower with the pressure of liquid self for the pressure atomization shower nozzle, and step-down influences greatly but its atomizing effect is loaded, and the droplet penetration power is poor, and mist droplet particle size liquid body viscosity influence is big; Though pneumatic nebulization shower nozzle atomization is superior to the pressure atomization shower nozzle, its atomizing air consumption is big, and it is bigger to consume energy.
Effervescent atomization spray medicine head can improve the adaptability of plant protection shower nozzle to the different viscosities soup, make droplet more carefully, more even, atomizing effect is better, to the control agricultural pest, promotes the agricultural produce good harvest, effective energy savings, it is significant to alleviate environmental pollution.
Summary of the invention
The objective of the invention is to, a kind of adaptability that can improve the plant protection shower nozzle to the different viscosities soup is provided, make droplet more carefully, more even, the better effervescent atomization dispenser of atomizing effect shower nozzle.
The present invention includes sprayer body, spray sheet, pipe joint, sprinkler cap, it is characterized in that being provided with the sprayer body inner chamber in the described sprayer body, the sprayer body inner chamber is made up of contraction chamber, cavum laryngis, expansion chamber; Described sprayer body contraction chamber is up big and down small platform shape, and described sprayer body cavum laryngis is cylindric, is positioned at the contraction chamber below; Body diameter is identical with the contraction chamber end diameter, and described sprayer body expansion chamber is up-small and down-big platform shape, and end diameter is identical with the cavum laryngis diameter; Be positioned at the cavum laryngis below, be provided with bubble generator in the sprayer body, described bubble generator is hollow cylinder; End is taper, and the bubble generator tail end is provided with the staggered injecting hole in space, and bubble generator links with air inlet pipe joint and sprayer body; Sprayer body one side is provided with inlet opening, and sprayer body lower end and sprinkler cap join, and is provided with sealing ring therebetween; The spray sheet embeds in the sprinkler cap, and spray sheet top is provided with spray sheet briquetting, and described briquetting is the cylinder that the center is provided with aperture; Briquetting and sprinkler cap are tight fit, and feed tube links with feed tube joint and sprayer body.
In order to make gas can inject liquid preferably; Form uniform biphase gas and liquid flow; Increase the momentum conversion between gas, the liquid simultaneously; Improve the atomizing momentum of gas-liquid mixture, the injecting hole center line on the bubble generator preferably becomes 38 °～50 ° with the angle of sprayer body bubble generator axis.
During use, air pump is simultaneously respectively to bubble generator and receiver air feed, at this moment; Gas gets in the sprayer body through bubble generator and forms the gas-liquid mixed chamber by the injecting hole entering sprayer body and the sprinkler cap that steep generator, and soup is got in the tube chamber of sprayer body, behind the sprayer body contraction chamber by the inlet with the bubble generator vertical direction under the effect of air pressure simultaneously; Liquid is accelerated and boosts; Behind cavum laryngis, liquid is by current stabilization and voltage stabilizing, again behind expansion chamber; Liquid expands rapidly, and with fully mix in that gas-liquid mixed is indoor from the Compressed Gas of bubble generator.
On the pipeline between air pump and the bubble generator; And be equipped with flow-controlling meter on the pipeline between receiver and the feed tube joint, and regulate charge flow rate and feed liquor flow to proper ratio, can form the gas-liquid bubble flow; After shower nozzle exports when spraying; Bubble sharply expands until blast because of the variation of external and internal pressure difference, forms more tiny drop, reaches good atomizing effect.
Compared with prior art, the present invention has and improves the adaptability of plant protection shower nozzle to the different viscosities soup, make droplet more carefully, more even, the better advantage of atomizing effect.
