Abstract
The utility model relates to a cold acrosol sprayer biphase flow sprinkler belonging to the agricultural pest control mechanical technical sphere, comprising a tubular sprinkler body, a concentric injector pipe is arranged in the center of the sprinkler body, one extensive end towards the sprinkler body opening of the injector pipe is produced as the shrink taper hole injector, the other end is connected with a liquid inlet pipe, an air inlet hole is arranged under the sprinkler body, a cochleatus guiding inclined plane is arranged inside the sprinkler body, the opening end of the sprinkler body are a capping are rotating fit, an orifice is arranged in the center of the capping, the injector extends to the hole from the smaller end of the orifice with smaller inside and larger outside of the capping, an air gap is left between circumference and the hole. The utility model forms an air and liquid mixed space more open than the internal mixing type, moreover the guiding inclined plane and the air gap rotate air flow more instantly, the mixed boost effect is better thereby jet pressure is less and ideal atomization injecting effect is generated.
Description
Technical field
The utility model relates to a kind of shower nozzle that sprays fluid, and the architecture advances of the gas that uses on especially a kind of normal-temperature fog machinery, liquid two-phase flow shower nozzle belongs to the agricultural plant protection field of mechanical technique.
Background technology
Existing normal-temperature fog machinery mainly is made up of injecting-unit, spray tank, agitating device, several parts of air compressor.Agitating device keeps the spray tank herb liquid is stirred during work, when spraying, the compressed air that air compressor produces produces negative pressure from the shower nozzle of injecting-unit, with the soup sucking-off in the spray tank, eject with air-flow, the air stream of the axial flow blower at shower nozzle rear generation simultaneously sprays away after gas, the liquid mixed flow of shower nozzle ejection are further atomized.Understand according to the applicant, the shower nozzle of existing normal-temperature fog machinery adopts the internal-mixing structure, and promptly liquid and compressed air are in sprayer body internal mix atomizing back ejection.This structure is because the blending space of gas, liquid two-phase flow is narrow and small, and it is big to spray resistance, so spray amount is little, influences the result of use of normal-temperature fog machinery.
Summary of the invention
The purpose of this utility model is: at the problem that prior art exists, propose a kind of mixed aerosol effective, spray the little normal-temperature fog machinery two-phase flow shower nozzle of resistance, thereby make normal-temperature fog machinery have bigger emitted dose.
In order to reach above purpose, normal-temperature fog machinery two-phase flow shower nozzle of the present utility model comprises the sprayer body of cylindrical tube shape, the middle part of sprayer body is shaped on concentric blast tube, the end that blast tube stretches out to the sprayer body opening part is made the nozzle that shrinks taper hole, the other end is connected with feed tube, the sprayer body below is shaped on air admission hole, be shaped on spiral helicine guiding surface in the sprayer body, sprayer body openend and block screw, the block center is shaped on spray orifice, wherein nozzle extends this hole from the small end of the inner small and outside big tapered spray orifice of blocking a shot, and periphery leaves air gap with this hole.
After air admission hole and feed tube connect pressed gas, fluid supply respectively, after air-flow enters sprayer body from the below, form eddy flow, and go out with the air gap high-speed rotational of block spray orifice formation from nozzle by guiding surface, the abundant mixed aerosol of the liquid from feed tube with the nozzle ejection ejects again.Because spray orifice of the present utility model has formed gas, the liquid blending space of more opening wide than internal-mixing, and guiding surface and air gap more promptly rotate air-flow, have the better mixing booster action, it is little therefore to spray resistance, can produce even more ideal atomized spray effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structural representation of sprayer body among Fig. 1 embodiment.
Fig. 3 is the C-C partial sectional view among Fig. 2.
The specific embodiment
Embodiment one
As seen from Figure 1, sprayer body 8 middle parts of the normal-temperature fog machinery two-phase flow shower nozzle cylindrical tube shape of present embodiment are shaped on concentric disjunctor blast tube 9, the end that this blast tube 9 stretches out to sprayer body 8 opening parts is made and is shunk the nozzle 11 that taper hole extends tubule, and the other end screws by internal thread and pipe joint 4.Plug-in mounting feed tube 1 in the endoporus of pipe joint 4, feed tube 1 is fixing with pipe joint 4 by locking nut 2.Sprayer body 8 belows are shaped on the air inlet pipe 10 of disjunctor, and arcuate region of its inner about 150 degree is shaped on spiral helicine guiding surface 12 (referring to Fig. 2 and Fig. 3), and its openend and block 7 screw by screw thread.7 centers of blocking a shot are shaped on inner small and outside big tapered spray orifice.Nozzle 11 extends the spray orifice from the small end of block, and periphery leaves air gap with this hole.
In order to guarantee sealing, between feed tube 1 and the pipe joint 4 and between sprayer body 8 and the block 7 O RunddichtringO 5 and 6 are housed respectively.
After feed tube 1 and air inlet pipe 10 connect the spray tank and compressed air source of normal-temperature fog machinery respectively, compressed air enters sprayer body 8, under the guiding function of helical form guiding surface, form eddy flow, and the air gap high-speed rotational that forms from nozzle 11 and block spray orifice and going out, the abundant mixed aerosol of soup with nozzle 11 ejections ejects again.Experiment showed, with the internal-mixing shower nozzle and compare that it is little that present embodiment sprays resistance, the atomized spray better effects if.
In order further to strengthen the mixed aerosol and the jeting effect of gas, liquid two-phase, can make the air admission hole (not shown) that the footpath turns forward on tubule nozzle 11 tube walls before above sprayer body 8 middle part blast tubes 9, air-flow promptly plays before the nozzle ejection at liquid and helps the spray immixture like this, has better diffusion effect when making the liquid ejection, be more convenient for by the aerodynamic atomization that goes out from the air gap rotation, emitted dose is bigger, and range is farther.
