Description

Rotary spray nozzle system {Rotary spray nozzle system}

The present invention relates to a rotary injection nozzle system, and more particularly, to a rotary injection nozzle system capable of injecting a fluid to be injected in various directions.

A spray device that sprays fluid can be divided into a single-fluid spraying method and a two-fluid spraying method according to the number of fluids used. It is a method widely used in labor-intensive farming in the past, and the two-fluid spraying method sprays air at a relatively low pressure (approximately 5 bar) through a nozzle, and the air is sprayed at a high speed. It is characterized in that the liquid in the liquid is sucked out according to Bernoulli's principle and can be dispersed far in the form of mist along with the air, so it is widely used in agriculture, livestock industry, and city quarantine in recent years.

In addition to the two-fluid spraying method, the rotary type fluid sprayer receives fluid from the fluid supply means and supplies it to the rotating nozzle to be sprayed, thereby achieving the purpose of evenly spraying while widening the spraying range of the fluid, reducing manpower shortage. Since there is an advantage of being able to replace it, research on this is being conducted. Since the rotary type double-fluid sprayer needs to solve the problem of twisting the two fluids while rotating, various developments have been made to solve the problem of twisting the double-fluid tube.

In the prior art, in order to prevent the two fluids from being twisted together, compressed air from the second housing enters the first housing through a drive shaft and is rotated together with the medicine container in the first housing so that the medicine is sprayed, so that the medicine is sprayed while rotating. Although the body is configured to spray while preventing twisting, the bulky drug container must be rotated together to prevent twisting, so energy is excessively entered and the place where it can be installed is limited due to the increase in volume, while the weight of the drug container There is a problem in that it is difficult to achieve the basic purpose of long-distance spraying because rotation of the spray nozzle is not smooth.

In addition, the interference member 750 is formed to have a smaller outer diameter than the inner diameter of the air jetting body 710 so that a passage through which air passes is provided between the outer circumferential surface and the inner circumferential surface of the air jetting body 710 . Since the air passing through the passage hole 735 of the separation support member 733 collides with the corresponding interference member 750 and spreads, the air passes through the spray hole 712 more uniformly. In addition, since the passage through which air passes in the inner space 711 of the air jetting body 710 is narrowed by the interference member 750, the flow rate of air may increase.

Meanwhile, although not shown in the drawing, diffusion grooves may be formed on the outer circumferential surface of the interference member 750 to guide the diffusion of the corresponding air. The diffusion groove is formed to be drawn inward to a predetermined depth with respect to the outer circumferential surface of the interference member 750, and the front and rear surfaces are respectively opened based on the flow direction of air in the internal space 711. In addition, the diffusion groove may be formed such that its width increases from the front end to the rear end. In addition, a plurality of diffusion grooves may be formed to be spaced apart from each other along the circumferential direction. The diffusion efficiency of the air passing through the interference member 750 is improved by the diffusion groove.

On the other hand, the body rotation unit 800 is not limited thereto, but any rotation means capable of rotating the rotation body 400 can be applied.

The operation of the rotary spray nozzle system 100 configured as described above will be described in detail.

First, the fluid to be injected is supplied to the fluid supply pipe 601 through the supply member of the fluid supply unit 600, and the fluid to be injected is supplied to the second sub-groove 303 of the main body 300 through the fluid supply pipe 601 and It is supplied to the second communication groove 402. The fluid to be sprayed introduced into the second communication groove 402 is supplied to the fluid ejection body 720 of the spray nozzle 700 through the fluid flow path 405 of the rotating body 400 .

Next, the air injection member of the air supply unit 500 injects high-pressure air into the first sub-groove 302 and the first communication groove 401 of the vane body through the air supply pipe 501 . The air injected into the first communication groove 401 is injected into the inner space 711 of the air jetting body 710 through the air flow path 404 of the rotating body 400, and passes through the air jetting body 710. It is injected into the injection hole 712. At this time, a high-speed air flow is formed around the outlet 741 of the spray nozzle 700 by the air sprayed from the spray hole 712 . Negative pressure is generated at the end of the jet body 740 of the jet nozzle 700 by the high-speed air flow, and the pressure on the outlet 741 side of the jet body 740 is relatively higher than the internal pressure of the fluid jet body 720. The fluid to be injected in the low receiving body 730 is injected to the outside through the outlet 741 .

In the rotary injection nozzle system 100 according to the present invention configured as described above, a flow path through which air and fluid flow is formed inside the rotary body 400 rotatably installed in the main body 300, and the corresponding flow Since air and fluid can be supplied to the injection nozzle 700 through the furnace, the structure is simple and the volume is relatively small, so there is an advantage in that it can be installed in more diverse locations.
