Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to an integrated gas-liquid mixing joint and a spraying system. Background Art

[0002] Spraying in gardens is the most important way of irrigation, disinfection and fertilization in existing orchards. Due to the large floor area of gardens and the large number of component units, reasonable spraying technology can bring huge benefits to gardens, and at the same time, it can reasonably control the costs of pesticides, fertilizers, etc. and avoid waste.

[0003] In the prior art, a Chinese patent with the patent application number CN202120859501.0 discloses a micro nozzle based on gas-liquid mixing spraying. In order to facilitate installation, spiked parts are arranged at both ends of the connecting pipe. The connecting pipe is connected to the liquid delivery pipe or the gas delivery pipe by inserting the spiked parts into the liquid delivery pipe or the gas delivery pipe. The liquid or gas in the liquid delivery pipe and the gas delivery pipe enters the mixing cavity in the middle of the connecting pipe and is mixed, and then sprays out from the strip-shaped or circular nozzle at the lower part of the mixing cavity. This type of prior art belongs to a plug-in nozzle. When installing, the spiked parts need to be inserted into the liquid delivery pipe or the gas delivery pipe. When there is a leak at the connection between the spiked parts and the liquid delivery pipe or the gas delivery pipe, the liquid delivery pipe or the gas delivery pipe needs to be replaced, resulting in the disadvantages of inconvenient installation and high maintenance cost of the spraying system using the plug-in nozzle. Summary of the Utility Model

[0004] Aiming at the disadvantages of inconvenient installation and high maintenance cost of the spraying system using the plug-in nozzle in the prior art, the purpose of the utility model is to provide an integrated gas-liquid mixing joint and a spraying system. The integrated gas-liquid mixing joint realizes the integration of connection and spraying functions through a more concise structure, reduces the manufacturing cost of the product and improves the service life of the product.

[0005] The utility model is realized by the following technical solutions: an integrated gas-liquid mixing joint, comprising a housing and a diversion pipe. A main joint channel is arranged in the inner cavity of the housing. The housing is of an integrated structure and is provided with a perforation for installing the diversion pipe.

[0006] The diversion pipe is installed on the housing through the perforation, and the inlet end of the diversion pipe is directly communicated with the main joint channel.

[0007] Two diversion pipes are respectively communicated with two main joint channels, and the outlet ends of the two diversion pipes face each other to form a converging nozzle.

[0008] It should be noted that the structure of the housing in the present utility model is independently developed. Therefore, the housing in the present utility model belongs to a non-standard part and needs to be custom processed. The structure of the flow guide pipe in the present utility model is a hollow pipe, usually a hollow round pipe. There are products with the same structure on the market. Therefore, it can be directly purchased on the market according to parameters such as the designed size and material, or custom processed.

[0009] Working principle: After fluids such as gas and liquid flow to the main passage of the joint of the integrated gas-liquid mixing joint, a part of the fluid flows from the inlet end to the outlet end of the flow guide pipe. When fluids flow into both of the two flow guide pipes forming the confluent nozzle simultaneously, the two-way fluids will impact and mix with each other at the confluent nozzle. If one fluid is gas and the other is liquid, the gas-liquid mixing effect will be enhanced, which can not only improve the gas-liquid mixing efficiency but also ensure the mixing uniformity, and is applicable to a variety of industrial application scenarios. When only one flow guide pipe has fluid flowing in, according to different internal pressures, the fluid will be released in ways such as a direct current columnar shape, an intermittent shape, a jet shape, etc., which is applicable to scenarios such as drip cooling.

[0010] In some embodiments, the flow guide pipe is in interference fit with the perforation. The inlet end and the outlet end of the flow guide pipe can be flat-headed or pointed. The outlet end of the flow guide pipe can also be grooved according to the requirements of different application scenarios to change the flow direction. The outlet end of the flow guide pipe extends out of the perforation.

[0011] In some embodiments, the integrated gas-liquid mixing joint further includes a fastener provided with a limit installation groove and a hook structure; at this time, a limit installation strip is provided on the housing;

[0012] The limit installation groove is used to install the fastener itself on the housing after being paired with the limit installation strip on the housing;

[0013] The hook structure is used to contact the outer wall of the flow guide pipe and clamp the flow guide pipe on the housing.

[0014] In some embodiments, the configuration of the hook structure for contacting the outer wall of the flow guide pipe has a large opening and a small closing, and includes an arc portion and guiding portions extending outward from both ends of the arc portion.

[0015] In some embodiments, a positioning structure is further provided on the fastener.

[0016] In some embodiments, the flow guide pipe is not fixedly installed on the housing; under the action of an external force, the flow guide pipe can move axially along the perforation to change the length of the outlet end of the flow guide pipe extending out.

[0017] In some embodiments, the inlet end of the flow guide pipe extends into the main passage of the joint, or the inlet end of the flow guide pipe is tangent to the main passage of the joint.

[0018] In some embodiments, a buckle for externally connecting an auxiliary positioning structure is further provided on the housing.

[0019] In some embodiments, the housing is integrally formed by an injection molding method.

[0020] In some embodiments, the diversion pipe is a seamless metal pipe or a plastic pipe.

[0021] The present utility model further provides a spraying system, including a fluid delivery device, a fluid delivery pipe, and a control device. The above-mentioned integrated gas-liquid mixing joint is installed on the fluid delivery pipe;

[0022] The control device is used to control the start-stop state and working parameters of the fluid delivery device after being electrically connected to the fluid delivery device;

[0023] The fluid delivery device is used to access a fluid supply source and switch the start-stop state or change the working parameters according to the instructions of the control device; when the fluid delivery device works, it can introduce the fluid into the fluid delivery pipe;

[0024] The fluid delivery pipe is used to deliver the fluid according to the designed route;

[0025] The integrated gas-liquid mixing joint is used to be installed on the fluid delivery pipe to release the fluid at a fixed point.

[0026] Compared with the prior art, the present utility model has the following advantages and beneficial effects.

[0049] Embodiment 1:

[0050] This embodiment provides an integrated gas-liquid mixing joint, as shown in, including a housing 1 and a diversion pipe 3, and the housing 1 is an integrated structure. As shown in, the solid of the housing 1 is provided with a perforation 12 for installing the diversion pipe 3, and the inner cavity of the housing 1 is provided with a main joint channel 11. As shown in, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 shown, including a housing 1 and a diversion pipe 3, and the housing 1 is an integrated structure. As shown in, Figure 2 、 Figure 4 shown, the solid of the housing 1 is provided with a perforation 12 for installing the diversion pipe 3, and the inner cavity of the housing 1 is provided with a main joint channel 11. As shown in, Figure 1 、 Figure 3 、 Figure 5As shown, the guide tube 3 is installed on the shell 1 through the through hole 12, and the inlet end of the guide tube 3 is directly connected to the joint main channel 11; the two guide tubes 3 are respectively connected to the two joint main channels 11, and the outlet ends of the two guide tubes 3 are opposite to each other to form a converging nozzle.

[0051] First of all, it should be explained that the shell 1 is an integrated structure, which means that the "shell 1" is an independent, non-detachable part. Normally, the "flow guide tube 3" is also an independent, non-detachable part. "Shell 1" and "flow guide tube 3" are two types of basic parts that make up the integrated gas-liquid mixing joint described in this embodiment. Since the structure of the shell 1 is independently developed, there are no ready-made products on the market that can be purchased directly, so it is manufactured by custom processing, and the common processing method is injection molding. The essence of the flow guide tube 3 is a hollow tube, which can be customized according to design requirements such as size and material, or it can be purchased directly on the market.

[0052] Furthermore, in this embodiment, the connection between the flow guide tube 3 and the housing 1 is a fixed connection. However, the fixed connection here is in a broad sense, which only means that the flow guide tube 3 will not move on the housing 1 at will when there is no external force. In other words, after the flow guide tube 3 is installed on the housing 1, it can be completely fixed and can also change its relative position under the action of external force.

[0053] Secondly, it should be noted that the integrated gas-liquid mixing joint in this embodiment is installed on an external pipe such as a fluid delivery pipe when it is actually used, and the fluid in the fluid delivery pipe can enter the joint main channel 11. Therefore, the end of the joint main channel 11 is the structure where the housing 1 in this embodiment is connected to an external pipe such as a fluid delivery pipe, which is recorded as an interface portion 15.

[0054] Furthermore, in actual use, the integrated gas-liquid mixing joint in this embodiment can be externally connected or internally connected. For the external connection type, the inner diameter of the interface part 15 of the shell 1 is required to be larger than the outer diameter of the external pipe such as the fluid delivery pipe, and the interface part 15 of the shell 1 is sleeved on the external pipe such as the fluid delivery pipe. For the internal connection type, the outer diameter of the interface part 15 of the shell 1 is required to be smaller than the inner diameter of the external pipe such as the fluid delivery pipe, and the interface part 15 of the shell 1 is sleeved in the external pipe such as the fluid delivery pipe. The specific connection method can be set according to the actual situation. Usually, the fluid delivery pipe adopts a plastic hose such as a PVC hose and a PE hose, and the pipe mouth of the plastic hose can be stretched open by the interface part 15 of the shell 1 and then tightly sleeved on the interface part 15. In addition, in order to further strengthen the connection between the interface part 15 and the fluid delivery pipe, a sealing ring, a reinforcement piece, etc. can be added to seal and reinforce the connection. Since the sealing and reinforcement by sealing rings and reinforcement pieces when the joint is connected to the pipe fitting belongs to the conventional technical means in the field, it is not an improvement point of this embodiment, so it is not shown in the figure.

[0055] Furthermore, it should be noted that the "confluence nozzle" in this embodiment is not a physical structure, but a space formed by the outlet ends of two diversion tubes 3 being close to or even in contact with each other for the mixing of two fluid paths. When the outlet ends of the two diversion tubes 3 face each other to form a confluence nozzle, the poses of the outlet ends of the two diversion tubes 3 will affect the state of fluid release, the coverage range, etc. Further, in actual use, fluid may not flow out of the two diversion tubes 3 simultaneously, and it can be adjusted according to the specific usage mode.

[0056] It should also be noted that the inlet end of the diversion tube 3 extends into the main passage 11 of the joint, or the inlet end of the diversion tube 3 is tangent to the main passage 11 of the joint. There is no strict limit on the length of the inlet end of the diversion tube 3 extending into the main passage 11 of the joint, as long as the fluid in the main passage 11 of the joint can be smoothly introduced into the inner cavity of the diversion tube 3.

[0057] Embodiment 2:

[0058] Based on the technical concept of Embodiment 1, this embodiment provides an integrated gas-liquid mixing joint, which is composed of only two types of parts, namely the housing 1 and the diversion tube 3. Several typical structures of the integrated gas-liquid mixing joint at this time are as Figure 1 , Figure 3 , Figure 5 , Figure 6 shown. The housing 1 is an integrated structure. The solid of the housing 1 is provided with a perforation 12 for installing the diversion tube 3, and the inner cavity of the housing 1 is provided with a main passage 11 of the joint. The diversion tube 3 is installed on the housing 1 through the perforation 12, and the inlet end of the diversion tube 3 is directly communicated with the main passage 11 of the joint; the two diversion tubes 3 are respectively communicated with two main passages 11 of the joint, and the outlet ends of the two diversion tubes 3 face each other to form a confluence nozzle.

[0059] Based on the principle of "an integrated gas-liquid mixing joint composed of only two types of parts, namely the housing 1 and the diversion tube 3", this embodiment further provides a typical structure of the integrated gas-liquid mixing joint. The integrated gas-liquid mixing joint with this typical structure is composed of only one housing 1 and two diversion tubes 3.

[0060] In the solution described in Embodiment 1, in addition to the two types of parts, the housing 1 and the diversion tube 3, there may be other types of parts. However, the housing 1 and the diversion tube 3 are necessary basic parts; while the solution described in this embodiment is composed of only two types of parts, the housing 1 and the diversion tube 3, without involving other components, emphasizing that the integrated gas-liquid mixing joint can be assembled only through the two types of parts, the housing 1 and the diversion tube 3, and the structure is extremely concise.

[0061] Embodiment 3:

[0062] Based on Embodiment 1, this embodiment provides two technical ideas on how to achieve a fastening connection after the diversion pipe 3 is installed on the housing 1: One technical idea for achieving a fastening connection is to utilize only the structural features of the diversion pipe 3 and the housing 1 itself, such as: the diversion pipe 3 is in interference fit with the through-hole 12 on the housing 1; Another technical idea for achieving a fastening connection is to add a connecting member, such as: adding a fastener 5.

[0063] When adding the fastener 5, the typical structure of the integrated gas-liquid mixing joint is as Figure 7 shown. As Figure 9 shown, a limit installation strip 13 needs to be provided on the housing 1. As Figure 10 、 Figure 11 shown, the added fastener 5 is provided with a limit installation groove 51 and a hook structure 52. The limit installation groove 51 is used to install the fastener 5 itself on the housing 1 after being paired with the limit installation strip 13 on the housing 1; The hook structure 52 is used to contact the outer wall of the diversion pipe 3 and clamp the diversion pipe 3 on the housing 1. At this time, the diversion pipe 3 can be clamped by the added fastener 5 to improve the installation stability of the fastener 5; The installation stability of the fastener 5 can also be further improved by the relative position relationship and the friction generated by the contact among the housing 1, the fastener 5, and the diversion pipe 3.

[0064] The above two technical ideas for achieving a fastening connection are not opposed and can also be used simultaneously, such as: both adding the fastener 5 and ensuring the interference fit relationship between the diversion pipe 3 and the through-hole 12 on the housing 1.

[0065] It should be noted that the above technical solutions for achieving the fastening connection of the diversion pipe 3 on the housing 1 can all achieve the connection method of non-fixed installation of the diversion pipe 3 on the housing 1. At this time, under the action of an external force, the diversion pipe 3 can move along the axial direction of the through-hole 12 to change the length of the outlet end of the diversion pipe 3 extending out.

[0066] In some embodiments, as Figure 11 、 Figure 12 shown, the configuration of the hook structure 52 for contacting the outer wall of the diversion pipe 3 has a large opening and a small closing, including an arc portion 521 and a guiding portion 522 that expands outward from the two ends of the arc portion 521. At this time, the structure of the hook structure 52 for connecting the diversion pipe 3 is similar to a "ji" character shape, which is convenient for guiding the hook structure 52 to quickly sleeve the diversion pipe 3.

[0067] In some embodiments, the configuration of the hook structure 52 for contacting the outer wall of the diversion pipe 3 is similar to a long U-shaped hairpin, and the opening is elastic to better clamp the outer wall of the diversion pipe 3.

[0068] In some embodiments, as Figure 10As shown, a positioning structure 53 is further provided on the fastener 5, which is beneficial to the positioning connection between the diversion pipe 3 and the housing 1.

[0069] Other parts of this embodiment are the same as those of Embodiment 1, so they will not be described in detail.

[0070] Embodiment 4:

[0071] This embodiment is further described on the basis of any one of Embodiments 1 - 3. A buckle 14 for externally connecting an auxiliary positioning structure is further provided on the housing 1. Considering the installation stability problem when the integrated gas-liquid mixing joint is connected to the fluid delivery pipe of the spray system, this embodiment provides a solution of adding the buckle 14 on the housing 1. At this time, the integrated gas-liquid mixing joint can be connected to external auxiliary positioning structures such as a fixed rod, a support frame, and a guardrail through the buckle 14 to improve the installation stability.

[0072] In this embodiment, the housing 1 is still an integrated structure, and the buckle 14 is a part of the housing 1 entity.

[0073] As long as it does not affect the installation of the integrated gas-liquid mixing joint itself, the number of buckles 14 provided on one housing 1, the position of the buckles 14, and the opening method of the buckles 14 are not strictly limited. However, from the perspective of practicality, usually one or two buckles 14 are designed on one housing 1. When two buckles 14 are designed, they are usually symmetrically arranged on the left and right sides of the housing 1.

[0074] As Figure 3 shown, the integrated gas-liquid mixing joint is designed with one buckle 14, and the clamping direction of this buckle 14 is consistent with the flow direction of the main channel 11 of the joint. When only one buckle 14 is designed, referring to the Figure 3 , Figure 4 shown orientation, this buckle 14 is located on the side of the integrated gas-liquid mixing joint; it is also possible to design this buckle 14 on the top of the integrated gas-liquid mixing joint, that is, on the opposite side of the converging nozzle. Since the function of the buckle 14 is to assist in fixing the position and pose of the integrated gas-liquid mixing joint, the specific position can be adjusted according to actual needs, so it will not be described in detail.

[0075] As Figure 5 shown, the integrated gas-liquid mixing joint is designed with two buckles 14, and the clamping direction of these buckles 14 is consistent with the flow direction of the main channel 11 of the joint.

[0076] As Figure 6 shown, the integrated gas-liquid mixing joint is designed with two buckles 14, and the clamping direction of these buckles 14 is perpendicular to the flow direction of the main channel 11 of the joint.

[0077] Taking the example of the integrated gas-liquid mixing joint being assisted in positioning and installed on a fixed rod through the buckle 14, as Figure 13 ,Figure 14 As shown, it can achieve vertical spraying, horizontal spraying or spraying in any other direction. For example Figure 15 , Figure 16 As shown, it is also possible to install an integrated gas-liquid mixing joint with different directions of the buckle 14 at the same point to achieve spraying in multiple directions.

[0078] Other parts of this embodiment are the same as any one of Embodiments 1-3, so they will not be described in detail.

[0079] Embodiment 5:

[0080] This embodiment is further described on the basis of any one of Embodiments 1-4. The housing 1 is integrally formed by injection molding using common plastic materials such as polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), and polyamide (PA). The diversion pipe 3 is a seamless metal pipe and is formed by extrusion.

[0081] In some embodiments, the diversion pipe 3 is made of common metal materials, such as: copper or copper alloy, aluminum or aluminum alloy, stainless steel, etc. The housing 1 already has an integral structure that can improve the sealing performance of the joint. When the diversion pipe 3 is a seamless metal pipe, the sealing performance of the entire integrated gas-liquid mixing joint can be further improved.

[0082] In some embodiments, the diversion pipe 3 is made of common plastic materials such as polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), and polyamide (PA), and is integrally formed by injection molding. Further, when the diversion pipe 3 is made of a plastic pipe, it is preferably made of the same material as the housing 1.

[0083] Other parts of this embodiment are the same as any one of Embodiments 1-4, so they will not be described in detail.

[0084] Embodiment 6:

[0085] Based on any one of Embodiments 1-5, this embodiment provides an integrated gas-liquid mixing joint, which includes an integrally structured housing 1 and two diversion pipes 3. Two joint main channels 11 are provided in the inner cavity of the housing 1, and a perforation 12 is provided on the side wall of each joint main channel 11 for installing the diversion pipe 3. The inlet ends of the two diversion pipes 3 are far apart, the outlet ends are close together and form a converging nozzle. At this time, the two diversion pipes 3 are in an inverted "V" shape in space. During use, each of the two joint main channels 11 is connected to a fluid delivery pipe for supplying liquid and gas.

[0086] In order to ensure that the pressurized fluids flowing out of the diversion pipes 3 forming the converging nozzle converge to form a counter-jet, the ideal state is to make the central axes of the diversion pipes 3 forming the converging nozzle intersect. Therefore, when designing the housing 1, the central axes of the perforations 12 for installing this group of diversion pipes 3 intersect.

[0087] Based on the above structure, a spraying system is proposed, including a fluid delivery device, a fluid delivery pipe, a control device, and multiple nozzles. The nozzles adopt the above-mentioned integrated gas-liquid mixing joint.

[0088] The control device is used to control the start-stop state and working parameters of the fluid delivery device after being electrically connected to the fluid delivery device;

[0089] The fluid delivery device is used to connect to a fluid supply source and switch the start-stop state or change the working parameters according to the instructions of the control device; when the fluid delivery device is working, it can introduce fluid into the fluid delivery pipe;

[0090] The fluid delivery pipe is used to transport fluid along a designed route;

[0091] The integrated gas-liquid mixing joint is used to be installed on the fluid delivery pipe to release fluid at a fixed point.

[0092] The above-mentioned integrated gas-liquid mixing joint has multiple functions such as atomization, water spraying, and regional temperature regulation.

[0093] When the atomization function needs to be realized, the valves of the two fluid delivery pipes are opened simultaneously. One is for liquid supply and the other is for gas supply. After the liquid and gas enter the main joint channel 11 of the integrated gas-liquid mixing joint respectively, part of the liquid and gas will pass through their respective corresponding diversion pipes 3 and converge and impact at the confluence nozzle, forming a fog-like release. By adjusting parameters such as the pressure, flow rate, and flow velocity of the liquid and gas, the atomization distance and / or area can be adjusted. This function is mainly applicable to scenarios such as spraying pesticides and fertilizing.

[0094] When the water spraying function needs to be realized, the valve of the fluid delivery pipe is opened, only for liquid supply and no gas supply. After the liquid enters the main joint channel 11 from the fluid delivery pipe, it forms a water droplet release at the confluence nozzle through the diversion pipe 3. By adjusting parameters such as the pressure, flow rate, and flow velocity of the liquid supply, the spraying distance and / or coverage area can be adjusted. This function is mainly applicable to watering or liquid fertilizing. When specifically using the water spraying function, one path can be controlled to work alone or two paths can be controlled to work simultaneously through the valve.

[0095] When the function of regional temperature adjustment needs to be realized, open the valve of the fluid delivery pipe, only supply gas and do not supply liquid. After the gas enters the main channel 11 of the joint from the fluid delivery pipe, it forms an air mass release at the confluence nozzle through the diversion pipe 3, agitating the flow of the surrounding air to achieve heat transfer. When specifically using the function of regional temperature adjustment, it can be controlled to work alone for one path or two paths simultaneously through the valve. In theory, the function of regional temperature adjustment can be achieved by inputting gas with a temperature different from the regional environment temperature. For example, inputting high-temperature gas to increase the temperature of the regional environment, or inputting low-temperature gas to decrease the temperature of the regional environment. In actual use, when heating is required, it is usually achieved by releasing heat source gas through the integrated gas-liquid mixing joint, but when cooling is required, it is usually achieved through the atomization function.

[0096] It should be noted that when realizing the atomization function, it is necessary for both fluid delivery pipes connected by the integrated gas-liquid mixing joint to work, with one supplying liquid and the other supplying gas; when realizing the water spraying function or when realizing the function of regional temperature adjustment by supplying high-temperature gas, one or both fluid delivery pipes can work.

[0097] Furthermore, under normal conditions, the two sets of fluid delivery devices and fluid delivery pipes set in the spraying system supply liquid for one path and gas for the other path. If only one of the two fluid delivery pipes connected by the integrated gas-liquid mixing joint needs to work, there is no need for the docking relationship between the fluid delivery pipe and the fluid delivery device in the spraying system, and only the working state of the specific fluid delivery device and the on-off of the fluid delivery pipe need to be controlled through the control device. However, if both fluid delivery pipes connected by the integrated gas-liquid mixing joint need to supply liquid, both fluid delivery pipes need to be connected to the fluid delivery device connected to the liquid source. Similarly, if both fluid delivery pipes connected by the integrated gas-liquid mixing joint need to supply gas, both fluid delivery pipes need to be connected to the fluid delivery device connected to the gas source. It can be adjusted according to the actual situation during the specific use process.

[0098] Other parts of this embodiment are the same as any one of Embodiments 1 - 5, so they will not be elaborated here.

[0099] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention.
