Description

Technical Field

[0001] The present application relates to the technical field of spray equipment, and in particular to a multi-section high-pressure diffusion nozzle. Background Art

[0002] In the process of plant planting, a corresponding spraying system will be set up in the plantation area as needed. The spraying system is mostly used for spraying pesticides or irrigation. Of course, there are also spraying systems used in other places for dust reduction and cooling. They are all sprayed from the nozzle by pumping out a certain pressure of water through a pipeline. For example, when spraying blueberries, if the particle size is too small, it is easy to drift with the wind. If the particle size is too large, it is easy to knock off the white powder wrapped on the surface of the blueberry particles. The white powder contains the most important medical substance anthocyanin. Therefore, in the spraying of planting, the droplet particle size should be strictly controlled when spraying pesticides. When the particle size is small, the pesticide fog field is easily affected by the airflow, resulting in insufficient spraying; when the particle size is too large, it will cause drug waste. Therefore, for different crops, droplets with a reasonable particle size distribution should be selected to reduce the loss rate of pesticides. In terms of irrigation, the use of spray can effectively expand the contact area between crops and water. While replenishing soil moisture, the fog field will also reduce the greenhouse temperature and increase air humidity, thereby improving the local climate.

[0003] No matter what kind of application, the nozzle is an important component in the spraying process. For high-pressure diffused nozzles, the existing technology commonly uses single-section nozzles, which spray diffused mist from a single hole. However, in actual use, due to the large area to be sprayed, multiple nozzles are used to connect in the system. The water source obtained in some remote places has poor water quality, and even other impurities exist in the water. When these water flows are sprayed through the existing nozzles, on the one hand, the water outlet of the nozzle is easily blocked, causing the diffused spray to fail. Moreover, due to the large number of nozzles, it is easy to forget to replace them, which indirectly causes some areas not to be sprayed; on the other hand, the pressure of the system is not constant. When the nozzle is blocked or other situations occur, the system water pressure changes. The existing nozzles cannot be adjusted according to different water pressures. Under different pressures, the fog field sprayed by the single-hole nozzle is easily affected by excessive pressure, and the sprayed particle size is small, and the sprayed particle size is large when the pressure is low.

[0048] In view of the above problems, an embodiment of the present application provides a multi-section high-pressure dispersion nozzle. The technical solution of the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 A multi-section high-pressure dispersion nozzle is shown, comprising:

[0050] A chassis 1 having a plurality of first nozzles 14; and

[0051] A first spray chamber cover 2, wherein the first spray chamber cover 2 has a first connecting ring 21 at the bottom, a second through hole 28 at the top, and a plurality of second spray ports 26 around the second through hole 28; and

[0052] A third spray chamber cover 4, wherein the third spray chamber cover 4 has a third connecting ring 41 at the bottom and a threaded column 48 at the top, wherein a water flow channel 49 that runs through the entire third spray chamber cover 4 is arranged in the threaded column 48; and

[0053] Self-adjuster 8, self-adjuster 8 comprises positioning column platform 81, sliding column 82, sleeve 83 and spring 9; sliding column 82 is fixedly arranged above the center of positioning column platform 81, sleeve 83 is slidably arranged on sliding column 82, spring 9 is arranged between positioning column platform 81 and sleeve 83; and filter;

[0054] Among them, the first spray chamber cover 2 is set in plurality, one of which is set on the chassis 1 and is fastened to the chassis 1 through the first connecting ring 21, the remaining first spray chamber covers 2 are set above another one and are fastened to the cover body of the next first spray chamber cover 2 through the first connecting ring 21, the third spray chamber cover 4 is set above the topmost first spray chamber cover 2 and is fastened to the cover body of the first spray chamber cover 2 through the third connecting ring 41; the filter is set inside each spray chamber cover, and the upper and lower ends of the filter are respectively abutted against the upper and lower spray chamber covers; the self-regulator 8 is set at the center of the chassis 1, the sliding column 82 passes through all the spray chamber covers and is located at the center of the filter, the sleeve 83 is initially located in the middle of the third spray chamber cover 4 and seals the lower part of the filter, and the sleeve 83 slides on the sliding column 82 according to the water pressure entering the spray chamber cover.

[0055] In the present device, a plurality of first spray chamber covers 2 are provided to be connected to each other to form a plurality of spray chambers and a plurality of nozzles. The top of each first spray chamber cover 2 is provided with a plurality of second nozzles 26 to form a disk-shaped nozzle for diffuse spraying. The first spray chamber cover 2 at the bottom is blocked by the chassis 1 and forms a disk-shaped nozzle again. Through this arrangement, a plurality of nozzles are provided on a nozzle section. Even if several of them are blocked, the others can still work normally. At the same time, a filter is provided inside the spray chamber cover to filter the water flow. During use, impurities and the like can be blocked in the filter as much as possible, thereby avoiding the blockage of the nozzle. In addition, the present application also provides a self-regulator 8 that runs through all the spray chamber covers. The self-regulator 8 is adaptively and automatically adjusted through a spring and water pressure. When the water pressure is low, the sleeve 83 of the self-regulator 8 is located inside the first section of the nozzle, and the first section of the nozzle works normally. When the water pressure increases to a certain level, the water pressure forces the sleeve 83 to move downward along the slide column 82 to reach the second section of the nozzle for spraying, and so on until the sleeve 83 moves to the bottom. This structure facilitates automatic adjustment of the water pressure to use the sprayed tax particle size. On the other hand, even if one section of the nozzle is blocked, the other section of the nozzle can be used normally, which increases the service life of the overall nozzle, reduces the maintenance and replacement costs, and avoids the easy loss of replacement, thereby indirectly causing the defect of not spraying in some areas.

At the same time, a first sealing groove 22 is constructed inside the first connection ring, and an inner sealing ring 10 is embedded in the first sealing groove 22, so that the first spray chamber cover 2 can be sealed when it is connected and fastened to the chassis 1.

[0067] In order to facilitate the sliding column 82 of the self-regulator and the sleeve slidingly connected to the sliding column 82 to pass through each first spray chamber cover 2, a second through hole 28 is constructed on the top thereof. At the same time, in order to facilitate the formation of a multi-section nozzle, a plurality of second nozzles 26 are constructed around the second through hole 28. At the same time, a first connecting disk 29 is arranged on the top of the first cylindrical cover body 24, and a second partition plate 25 is arranged on the first connecting disk 29. The second partition plate 25 is fastened to the second connecting ring 31 of the second spray chamber cover 3 thereon to form a second section nozzle.

Similarly, the second connecting ring 31 is connected to the top of the second partition plate 25 and is fastened by means of a screw window through the second connecting hole 33. A second sealing groove 32 is arranged on the inner side of the bottom of the second connecting ring 31 and an inner sealing ring 10 is embedded therein for sealing and at the same time forming a nozzle of the second nozzle section. The second cylindrical cover body 34 is integrally connected to the bottom with a second connecting disc 39 and a third partition plate 35 is arranged thereon.

A third through hole 38 is arranged on the top of the second spray chamber cover 3 for the sliding column 82 and the sleeve 83 of the self-regulator 8 to pass through.

[0068] Due to the need to connect with the pipe of the spraying system, the structure of the third section of the spray head formed by the third spray chamber cover 4 is different from that of the first spray chamber cover 2 and the second spray chamber cover 3. Specifically, the third spray chamber cover 4 includes a third connecting ring 41, a third sealing groove 42, a third connecting hole 43, a third cylindrical cover body 44, a third positioning groove 45, a fourth positioning groove 46, a fourth sealing groove 47, a threaded column 48, and a water flow channel 49; the third connecting ring 41 is connected and fixedly arranged on the bottom outer side of the third cylindrical cover body 44, and a third connecting hole 43 is constructed on the third connecting ring 41. A screw is arranged in the third connecting hole 43 to connect and fasten with the second connecting disc 39 of the second spray chamber cover 3; the threaded column 48 is fixedly arranged at the center top of the third cylindrical cover body 44, and a third sealing groove 42 is also arranged on the inner side of the third connecting ring 41, and an inner sealing ring 10 is also arranged therein to seal when connected. An outer sealing ring 101 is arranged in the fourth sealing groove 47 at the top so that the threaded column 48 is sealed when connected with the pipeline.

[0069] In the present application, a first filter 5 is arranged in the first spray chamber cover 2, a second filter 6 is arranged in the second spray chamber cover 3, and a third filter is arranged in the third spray chamber cover 4. The three filters are of the same structure and include a lower connecting positioning ring 51, an upper connecting positioning ring 52, a connecting column 53, a filter mesh 54, and a connecting hole 55; the lower connecting positioning ring 51 and the upper connecting positioning ring 52 are arranged as two rings, a connecting column 53 is arranged between the lower connecting positioning ring 51 and the upper connecting positioning ring 52, the filter mesh 54 is cylindrical and fixedly arranged between the lower connecting positioning ring 51 and the upper connecting positioning ring 52 and located on the inner side of the connecting column 53, and a connecting hole 55 is arranged in the center of the lower connecting positioning ring 51 and the upper connecting positioning ring 52. At the same time, the top of the first spray chamber cover 2 is configured with a first positioning groove 27, and the first filter 5 is embedded in the first positioning groove 27; the top of the second spray chamber cover 3 is configured with a second positioning groove 37, and the top of the second filter 6 is embedded in it; the top of the third spray chamber cover 4 is configured with a third positioning groove 45, and the top of the third filter is embedded in it. In this way, it is convenient to position and fasten each filter.

[0070] At the same time, since the third section of the nozzle where the third spray chamber cover 4 is located should be working normally, the other two sections of the nozzles should not work, and the other two sections of the nozzles should work according to the change of water pressure. Therefore, the apertures of the second through hole 28, the third through hole 38 and the connecting hole 55 of each filter are preferably adapted to the outer diameter of the sleeve 83. The spring 9 of the self-regulator 8 is supported below the top of the sleeve 83. The spring 9 adopts a flexible spring and can be set to three working conditions of 1Mpa, 2Mpa and 3Mpa according to the needs. If necessary, one or two sealing rings with a circular cross section can be embedded on the inner wall of each through hole for sealing. Only when the water pressure is higher than the standard water pressure after the previous section of the nozzle is fully opened for work, the second section of the nozzle will be opened under the water pressure to work.

[0071] In the present application, in order to facilitate filtration, the filter mesh cloth is made of vertical carbon fiber mesh cloth, which is arranged in a circular shape between the lower connecting positioning ring 51 and the upper connecting positioning ring 52. The liquid flow channel has an inner spacing of 0.05mm and an outer spacing of 0.01mm. The liquid medicine passes through the vertical filter and flows out of the liquid flow channel. Impurities smaller than 0.05mm can be retained by the filter mesh cloth, and the remaining algae can be adsorbed by the mesh structure inside the carbon fiber mesh cloth.

[0072] When the present application is working, when the water pressure is less than 1Mpa, the liquid medicine enters from one side of the front end of the third filter 7 and flows out from the other side to the third nozzle 36 formed by the third partition 35 for spraying. The third nozzle 36 is set to make the water droplets reach an effective droplet particle size range of 40μm-200μm under the action of small pressure; when the water pressure is 1-2Mpa, the water pressure continues to push the sleeve 83 on the flexible spring to move downward, and the flexible spring is further compressed. At this time, part of the liquid medicine is sprayed out from the third nozzle 36, and part of it enters the cavity where the second spray cavity cover is located, and is sprayed out from the second nozzle after being filtered by the second filter 6;

[0073] When the water pressure reaches 2-3MPA, the water pressure continues to push the sleeve 83 on the flexible spring, and the flexible spring is further compressed. At this time, the first nozzle 14 needs to enter work, so the upper end of the first filter 5 should be opened, but because the bottom limits the movement of the sleeve 83, the length of the first cylindrical cover body 24 where the nozzle of the last section is located is longer than the nozzles at the first two ends so that when the sleeve 83 is compressed to the end, it can open this section of the first filter 5, so that water can be sprayed out normally. The present application sets the length of the first cylindrical cover body 24 of the bottom first spray chamber cover 2 to 1.5 times that of the others, or sets the length of the entire first spray chamber cover 2 to 1.5 times that of the other second spray chamber covers 3. In this way, when the sleeve 83 is compressed to the end, at least half of the first filter 5 is opened. Of course, it can also be directly set to 2 times as needed to fully open.

[0074] The high-pressure three-section high-pressure diffusion nozzle can also solve the technical problems of the existing nozzles being easy to leak and clog. The use of vertical carbon fiber mesh and replaceable filter core can prevent the nozzle from being easily clogged. On the other hand, the use of rubber sealing ring can effectively prevent the nozzle from leaking.

[0075] When designing the nozzle of the present application, in order to prevent the necessary pressure difference change that causes a large change in the sprayed fog field, the gap of the nozzle where the third spray chamber cover is located, or the angle of the flow channel column, is 2°. The flow channel column is a partition column with a fan-shaped inner circle cross-sectional area of ​​1.57×8mm2, an outer circle of 2.62×8mm2, and a length of 30mm. There are 96 baffle columns along the center of the circle, so the number of flow channels is 97, the water outlet cross-section of the inner flow channel is 8×1.3mm2, and the water outlet cross-section of the outer flow channel is 8×2.3mm2.

[0076] The gap of the nozzle where the second spray chamber cover is located or the angle of the flow channel column is 2°. The flow channel column is a partition column with a fan-shaped inner circle cross-sectional area of ​​1.57×8mm2, an outer circle of 2.62×8mm2, and a length of 30mm. There are 72 baffle columns along the center of the circle, so the number of flow channels is 73, the water outlet cross-section of the inner flow channel is 8×2.3mm2, and the water outlet cross-section of the outer flow channel is 8×3.9mm2.

[0077] The gap or flow channel angle of the nozzle where the first spray chamber cover is located is 2°. The flow channel column is a fan-shaped partition column with an inner circle cross-sectional area of ​​1.57×8mm2, an outer circle of 2.62×8mm2, and a length of 30mm. There are 54 baffle columns along the center of the circle, so the number of flow channels is 55, the water outlet cross-section of the inner flow channel is 8×3.6mm2, and the water outlet cross-section of the outer flow channel is 8×6.1mm2.

[0078] In this way, the pressure difference change is avoided by gradually reducing the number of flow channels, the change of the fog field caused by the pressure difference change is reduced, and the particle size of the sprayed water mist is kept uniform.
