Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of atomizing nozzles, in particular to the technical field of water-gas mixed jet atomizing nozzles, and specifically to a two-fluid atomizing nozzle. Background Art
[0002] Atomizing nozzles are one of the farmland irrigation equipment that sprays pressurized water into the air through the nozzles and scatters it in the form of mist in the fields and crops. They are suitable for flower fields, lawns, green spaces, factories, greenhouses, and agricultural water-saving irrigation. Various types of atomizing nozzles have been developed on the market, and each atomizing nozzle has its own unique features.
[0003] In order to provide a full coverage atomizing spray system for more flexible agricultural park spray layout, a large number of atomizing nozzles are needed. The applicant used the existing conical atomizing nozzles to arrange the park atomizing system. After actual spraying, it was found that for large-area spraying with long pipelines, the atomization effect was poor due to insufficient local pressure, and the atomization could not be effectively achieved. However, areas that are not fully atomized cannot achieve full coverage, and the spray water can only flow along the nozzles and pipelines, and the area of soil moisturized is extremely limited. In order to meet the needs of large-area unified atomizing spraying, the applicant provides a new atomizing nozzle to replace the existing atomizing nozzle, which is used for large quantities, long pipelines, and large-area unified spraying. Utility Model Content
[0004] In order to solve the problem of atomized spraying, the present application provides a two-fluid atomizing nozzle, which simultaneously introduces pressurized gas and pressurized liquid into the nozzle and achieves spatial mixing at the moment of spraying the two fluids, thereby producing a uniform atomization effect. The greater the fluid pressure, the better the atomization effect.
[0005] In order to achieve the above purpose, the technical solution adopted in this application is:
[0006] The two-fluid atomizing nozzle comprises a first fluid pipe for spraying a first pressure fluid and a second fluid pipe for spraying a second pressure fluid. The first fluid and the second fluid sprayed from the first fluid pipe and the second fluid pipe have an intersection angle of 45°-90°.
[0007] Preferably, the first fluid pipe and the second fluid pipe are symmetrically arranged with the same structure, and the first fluid pipe and the second fluid pipe are fixedly or detachably connected via a connecting piece.
[0008] Preferably, the first fluid pipe comprises a shell structure, in which a channel for the circulation of the first pressure fluid is arranged, one end of the channel is a nozzle, the other end of the channel is an inlet for the first pressure fluid, and the shell structure is provided with a spike portion or a connecting portion at the inlet end.
[0009] Preferably, when the shell structure is arranged as a connecting portion at the inlet end, the connecting portion is tightly connected to the joint by means of a threaded, clamping or snap-fitting structure.
[0010] Preferably, the axial direction of the spike portion of the shell structure disposed at the inlet end is horizontal, vertical, or at any angle between the horizontal and vertical.
[0011] Preferably, the channel is connected at one end close to the nozzle through a convergent section, and the cross-sectional area of the convergent section gradually decreases along the fluid direction.
[0012] Preferably, the cross-sectional shape of the nozzle is any one of a circle, a rectangle, a rhombus, an ellipse, and a parallelogram.
[0013] Preferably, the distance between the centers of the nozzles of the first fluid tube and the second fluid tube is between 1.5 mm and 5 mm.
[0014] Beneficial effects:
[0015] The two-fluid atomizing nozzle provided by the utility model is more suitable for atomizing spraying in large-area and long pipelines, and can significantly improve the problem of poor atomization effect caused by obvious pressure drop at the rear end due to increased pipeline length and increased number of nozzles. At the same time, the utility model can be directly inserted into the rubber pipeline without the need to install a joint separately, and is very convenient for installing multiple nozzles.
[0016] The utility model adopts the water-gas collision atomization principle.

[0034] Embodiment 1:
[0035] See the instruction manual Figure 1-Figure 7 The two-fluid atomizing nozzle shown comprises a first fluid pipe 1 for spraying a first pressure fluid and a second fluid pipe 2 for spraying a second pressure fluid. The first fluid and the second fluid sprayed from the first fluid pipe 1 and the second fluid pipe 2 have an intersection angle of 45°-90°.
[0036] Working principle:
[0037] The two-fluid atomizing nozzle provided in this embodiment is a structure that uses water-gas jet mixing to achieve atomization. A first pressure fluid, such as pressurized tap water or a pharmaceutical liquid, is passed into the first fluid pipe 1, and a second pressure fluid, such as compressed air, is passed into the second fluid pipe 2. Then, the fluids are sprayed out from the nozzles of the first fluid pipe 1 and the second fluid pipe 2 respectively and intersect and mix with each other to form atomized water droplets, thereby achieving the effect of atomizing spray. Figure 1 , Figure 5-Figure 6 As shown, the lower end of the two-fluid atomizing nozzle is connected to the water pipe and the air pipe respectively to work. The faster the spraying speed of the water flow and the air flow is, the better the atomization effect is.
[0038] Embodiment 2:
[0039] This embodiment is based on the embodiment 1 and further optimized. Figure 1-Figure 9 As shown, the first fluid pipe 1 and the second fluid pipe 2 are symmetrically arranged with the same structure, and the first fluid pipe 1 and the second fluid pipe 2 are fixedly or detachably connected by a connector 3. The structure provided in this embodiment can be molded by integral injection molding, and the manufacturing cost is greatly reduced compared with the existing conical nozzle; at the same time, during installation, the water / gas inlet end of the nozzle can be directly inserted into the water / gas hose to achieve atomized spraying.
[0040] In order to further expand the range of connection objects of the nozzle and meet different connection methods, in this embodiment, the first fluid pipe 1 includes a shell structure, and a channel 13 for the first pressure fluid to flow is provided in the shell structure. One end of the channel 13 is a nozzle 11, and the other end of the channel 13 is an inlet for the first pressure fluid. The shell structure is provided with a spike portion or a connecting portion at the inlet end. The spike portion is as follows: Figure 5 , Figure 8-Figure 9 As shown, the spike portion is designed mainly for connecting a plastic hose, and the connection can be completed by directly inserting the spike portion into the plastic hose. The connecting portion is a structure used to connect other joints used to connect water pipes or air pipes, so as to broaden the connectability of the nozzle provided by this embodiment.
[0041] As an optional structure for widening the connection, when the shell structure is located at the inlet end and is configured as a connecting portion, the connecting portion is sealed and connected to the joint by means of a threaded, clip-on or buckled structure.
[0042] In order to facilitate the installation layout of the water pipe and the air pipe and to facilitate the installation of the nozzle, the axial direction of the spike portion of the shell structure disposed at the inlet end is horizontally disposed, such as Fig. 9 As shown, vertical setting, such as Figure 8 As shown, or at any angle between horizontal and vertical, such as Figure 6 shown.
[0043] In this embodiment, in order to avoid the problem of reduced spraying effect due to flow rate limitation of channel 13, see Figure 5 As shown, the channel 13 is connected to the nozzle 11 at one end through a convergent section 12, and the cross-sectional area of the convergent section 12 gradually decreases along the fluid direction. In this way, the flow cross-sectional area of the fluid in the channel 13 is significantly larger than the flow cross-sectional area at the nozzle 11, so that the flow cross-sectional area at the nozzle 11 is the smallest, thereby maximizing the use of fluid pressure and providing the maximum jet velocity.
[0044] In this embodiment, the cross-sectional shape of the nozzle 11 is any one of a circle, a rectangle, a rhombus, an ellipse, and a parallelogram. Figure 2 Provided circular, Figure 3 The rectangle shown.
[0045] In order to convert the fluid pressure into the atomization effect to the greatest extent, in this embodiment, the distance between the centers of the nozzles 11 of the first fluid pipe 1 and the second fluid pipe 2 is between 1.5 mm and 5 mm. The larger the distance, the greater the loss of the fluid and the smaller the atomization range; conversely, the smaller the distance, the smaller the loss of the fluid kinetic energy and the larger the atomization range. However, if the distance is too small, the atomization range is not controllable and water droplets may splash.
[0046] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
