Description
Technical field
The present invention relates to a kind of dusting device, specifically refer to utilize the water of Rafael nozzle operation principle to revolve gas direct injection dusting device.
Background technology
Spray spraying pesticide is the operational means that agricultural, forestry and gardening are often used, and foliar spray agricultural chemicals can carry out except operations such as damage by disease and insect.In general, foliar spray agricultural chemicals is carried out to short crops, adjust the distance, the loss of the uniformity and energy requires all relatively low, but if carry out foliar spray agricultural chemicals to tall and big arbor, then the loss of spraying distance, the uniformity and energy is all had higher requirements, otherwise inconvenience part can be brought.
Existing dusting device is spraying done in the uniformity better, and the nozzle of atomization often can make to spray very even, but also exists to spray and be short of power, the defect that range is little.Therefore, under the condition that energy ezpenditure is low, make the distance of spraying far away as far as possible, become the difficult problem of pendulum in face of scientific worker.

The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, the water providing a kind of ingenious application Rafael nozzle operation principle to carry out spraying revolves gas direct injection dusting device, this spraying device has that structure is simple, energy conversion efficiency is high and the feature that jet length is far away, is particularly suitable for implementing dusting to high megaphanerophyte.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
A kind of water revolves gas direct injection dusting device, comprises outer tube and central tube, it is characterized in that: outer tube connects water tank, and water tank provides water to enter outer tube, and central tube connects compressed air reservoir, and compressed air reservoir provides pressed gas to enter central tube, outer tube and central tube are jacket type structure, and central tube front end is gas spout, and central tube compressed air enters daraf(reciprocal of farad) that curved surface expansion chambers by backward front straight spirt, the non-Full connected in tapering of central tube coaxially embeds outer tube, outer tube Inner guide cross section have reduce after the change procedure that amplifies again, pressure (hydraulic) water bores flow forward in tubular throttling passage between outer tube and central tube, daraf(reciprocal of farad) that curved surface expansion chambers is entered by helical flow path churning between cyclone and central tube, your curved surface expansion chambers of daraf(reciprocal of farad) is the mixing chamber that compressed air and pressure (hydraulic) water eddy flow enter simultaneously, daraf(reciprocal of farad) that effect makes gas-water mixture carry to the jet pipe in gas spout front, be connected with above jet pipe and add medicine glass, agricultural chemicals adds by adding medicine glass, eddy flow is particularly conducive to gas, water, the abundant mixing of agricultural chemicals, mixture is spouting by the spout high-speed uniform in jet pipe front.
Described outer tube and water tank connecting pipe road are provided with water valve, filter and pressure pump.
Described central tube and compressed air reservoir connecting pipe are provided with air valve.
Described compressed air reservoir connects air compressor machine, safety valve, manometer and bottom valve.
The present invention mainly carries out the optimal design of sprayer apparatus by flexible Application Rafael nozzle operation principle, can realize the most rational power conversion, makes dusting distance farthest, mixes the most even.
The operation principle of Rafael nozzle is such: the jet pipe of band trunnion, classical hydrodynamics is followed when Compressed Gas first progressively enters the narrowest and small throat's process by the pipe position that cross section is larger, cross section diminish flow velocity increase, resistance also significantly increases sharply, form the flowing of a kind of gas throttling, but the convergent divergent channel part that Compressed Gas progressively expands by entering cross section after throat's smallest cross-sectional, due to the decompressional expansion of Compressed Gas, gas no longer follows Classical Fluid Mechanics, but can be sprayed by convergent divergent channel with very high speed, if compression pressure is enough high and nozzle structure is reasonable, gas can spray from spout with supersonic speed.Rafael nozzle operation principle is applied to jet airplane and rocket, significantly improve efficiency and the power of jet engine, achieve space flight, the leaping of science and technology of aviation, playing your performance characteristic of daraf(reciprocal of farad) at this makes gas-liquid mixed spray mutually, far firing range, efficient, evenly, reach that agricultural chemicals is the most efficient, high-quality to be sprayed.
Mixing wastewater with air at a high speed ejection can realize the most reasonable conversion of energy, such compressed air energy that can make drives the also best diffusion injection of air water Homogeneous phase mixing, the composition that sprays wherein is made to spray to target, the very similar long tube rifle of longer jet pipe, advantageous particularly compressed air potential energy constantly promotes air-water mixture to preacceleration, realize high-speed uniform to spray from spout, impact, realize high-quality, the efficient spraying operation of agricultural chemicals.
Compared with prior art, beneficial effect of the present invention is also:
Can by regulating compressed air and water discharge pressure, make its flow and jet velocity reasonable; The restriction characteristic of gas-liquid runner can obtain the optimum mixture ratio example relation needed for required gas-liquid swirl injection; Gas phase, liquid phase enter mixing chamber together, and due to your effect of daraf(reciprocal of farad), compressed air expansion driven mixing wastewater with air is also spouting from spout at a high speed, the similar rifle long tube of longer jet pipe, make injection farther and gas-liquid evenly.
Apparatus of the present invention structure is simple, reliable, ingenious, cost is low, can most effectively compressed air potential energy be promoted gas-liquid homogenizing and be converted into injection flying power, realize the operation of the most efficient, high-quality pesticide application.
