Description

Technical Field

[0001] This application relates to the field of materials science and engineering, and in particular to an atomizing spray device. Background Technology

[0002] Salt spray testing is used to assess the salt spray corrosion resistance of products or metal materials. It is widely used in the salt spray corrosion detection of metal material protective layers, mechanical parts, electronic components, automotive parts, industrial products, aerospace, automobiles and motorcycles, electrical and electronic products, measurement, coatings, etc., to evaluate the corrosion resistance of material protective layers and products.

[0003] Key parameters for salt spray testing include test temperature, salt solution concentration, sample placement angle, solution pH, and salt spray deposition. Temperature, concentration, angle, and pH are relatively easy to control and adjust using common methods; for example, temperature control is well-established with an accuracy of ±0.1℃. However, adjusting salt spray deposition is more challenging. This is because the temperature difference between the inside and outside of the salt spray chamber causes crystals to easily precipitate and clog the nozzles, altering the deposition rate. Furthermore, the airflow inside the salt spray chamber, intended to maintain temperature uniformity, tends to blow in the same direction, resulting in uneven salt spray deposition.

[0004] In existing testing methods, the salt spray deposition rate is adjusted by adjusting the air inlet pressure of the nozzle. Increasing the air inlet pressure increases the salt spray deposition rate, while decreasing the air inlet pressure decreases the salt spray deposition rate. However, decreasing the air inlet pressure can also easily lead to crystal precipitation and clogging of the nozzle, ultimately resulting in uneven adjustment of the salt spray deposition rate.

[0005] Therefore, how to improve the uniformity of salt spray deposition is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0037] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. The described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.

[0038] To address the issue of uneven salt spray deposition in existing atomizing spray devices 10, this application describes the structure of the atomizing spray device 10 in detail with reference to the accompanying drawings:

[0039] like Figure 1 and Figure 2 As shown, this application introduces an atomizing spray device 10, including a spray assembly 100, a guide tube 200, a dispersion assembly 300, and a return assembly 400; the spray assembly 100 is fixed to the side wall of the guide tube 200, the guide tube 200 includes a first opening 210, the spray assembly 100 can extend into the first opening 210, and can spray parallel to the guide tube 200 into the guide tube 200; one end of the guide tube 200 is fixedly connected to the dispersion assembly 300, and the other end of the guide tube 200 is fixedly connected to the return assembly 400 to recover liquid.

[0040] In conducting salt spray simulation experiments, the atomizing spray device 10 provided in this application can be used. The spray component 100 generates salt spray and sprays it into the guide tube 200. The guide tube 200 guides the salt spray to the dispersion component 300, which then disperses the salt spray to other areas. By increasing or decreasing the number of atomizing spray devices 10, adjusting the length and diameter of the guide tube 200, and adjusting the air inlet pressure of the spray component 100, the uniformity of sedimentation can be improved.

[0041] The function of the spray assembly 100 is to convert a certain proportion of salt water into salt mist using high-pressure compressed air and spray it into the experimental environment, thereby simulating real marine salt mist conditions. The structural features of the spray assembly 100 will be described in detail below.

[0042] The spray assembly 100 includes a first support 110, a fixing block 120, a spray liquid pipe 130, and a compressed air pipe 140. The function of the spray liquid pipe 130 is to transport brine of a certain concentration. The structure of the spray liquid pipe 130 is that the inlet end is a cylindrical straight pipe section with a larger diameter, the transition section is a conical structure with a gradually tapering diameter, and the outlet end is a cylindrical straight pipe section with a smaller diameter. The advantage of this design is that the brine in the spray liquid pipe 130 can gradually increase in flow velocity under pressure as the pipe diameter decreases, and maintain the maximum flow velocity at the outlet, which is conducive to the formation of brine mist.

[0043] The function of compressed air pipe 140 is to continuously input compressed air at a certain pressure to impact and mix the brine at the outlet of spray liquid pipe 130 at high speed, thereby producing salt spray particles with uniform diameter. The overall structure of compressed air pipe 140 is L-shaped, with the long side of the L-shape being the inlet end. Similar to spray liquid pipe 130, the inlet end of compressed air pipe 140 is also a cylindrical straight pipe section with a relatively large diameter. The difference is that the transition section of compressed air pipe 140 is a right-angle bend with a gradually narrowing diameter, and the outlet end is a cylindrical straight pipe section with a smaller diameter, which is the short side of the L-shape of compressed air pipe 140. The short side of the L-shape is perpendicular to the long side of the L-shape. Since the long sides of the L-shapes of spray liquid pipe 130 and compressed air pipe 140 are parallel, the outlet end of spray liquid pipe 130 is also perpendicular to the outlet end of compressed air pipe 140. The advantage of this design is that, as compressed air enters through the inlet of the compressed air pipe 140, its flow rate gradually increases under the same pipe pressure due to the gradually decreasing pipe diameter, reaching a very high velocity at the outlet of the compressed air pipe 140. Furthermore, since the outlet of the compressed air pipe 140 is perpendicular to the outlet of the spray liquid pipe 130, the compressed air and salt water can collide and mix to the maximum extent, thereby improving the misting effect of the spray assembly 100.

[0044] To facilitate the connection between the spray liquid pipe 130 and the brine pipe while ensuring a tight connection, the inlet of the spray liquid pipe 130 includes a first clamping connector 131, which has a conical structure. Similarly, the inlet of the compressed air pipe 140 includes a second clamping connector 141, which also has a conical structure. This is because the brine transport pipe connected to the brine storage tank and the compressed air transport pipe connected to the compressed air storage tank typically use corrosion-resistant rubber hoses. The conical structure of the first clamping connector 131 and the second clamping connector 141 allows the rubber hoses to be smoothly connected to the spray liquid pipe 130 and the compressed air pipe 140. Furthermore, the conical end forms a barb shape, allowing the rubber hose to expand to its maximum and then contract appropriately, creating a gripping force and ensuring a tighter connection. This prevents water and air leaks, resulting in more accurate experimental results.

[0045] To maintain the relative positions of the spray liquid pipe 130 and the compressed air pipe 140 and ensure that their outlet angles remain fixed, the spray assembly 100 also includes a connector 150. The connector 150 typically uses a connecting rod made of the same material as the spray liquid pipe 130 and the compressed air pipe 140, and the connecting rod is integrally manufactured with the spray liquid pipe 130 and the compressed air pipe 140, thus ensuring a more secure connection between the connecting rod and the spray liquid pipe 130 and the compressed air pipe 140. The number of connectors 150 can be one or more. When there is only one connector 150, it can be I-shaped to ensure that the parts connected to the spray liquid pipe 130 and the compressed air pipe 140 are in surface contact. This ensures that the long sides of the L-shape of the spray liquid pipe 130 and the compressed air pipe 140 remain parallel, preventing relative displacement of the outlet ends of the spray liquid pipe 130 and the compressed air pipe 140, which helps maintain the stability of the spray effect. When there are at least two connectors 150, the lengths of at least two connecting rods are the same and they are kept parallel to each other. This ensures that the spray liquid pipe 130 and the compressed air pipe 140 remain parallel, which also helps maintain the stability of the spray effect.

[0046] To ensure the salt spray's movement direction aligns with the guide tube 200, the outlet cross-section of the spray liquid tube 130 is perpendicular to the outlet cross-section of the compressed air tube 140. Although the outlet ends of the compressed air tube 140 and the spray liquid tube 130 are perpendicular, the perpendicularity of their outlet cross-sectional areas still significantly impacts the salt spray's movement direction and atomization effect. Specifically, the airflow-liquid shear balance between the compressed air tube 140 and the spray liquid tube 130 is disrupted, leading to uneven salt spray particles and unstable negative pressure formed by the airflow passing over the end of the spray liquid tube 130. Therefore, it is necessary to maintain the perpendicularity between the outlet cross-section of the spray liquid tube 130 and the outlet cross-section of the compressed air tube 140. This ensures that the airflow passes perpendicularly over the outlet surface of the spray liquid tube 130, creating uniform suction. After gas-liquid mixing, the mixture is sprayed out in a symmetrical fan shape along the extension direction of the guide tube 200 from the end of the compressed air tube 140, maximizing the salt spray's movement along the guide tube 200 and ensuring uniform distribution to the dispersion component 300, resulting in more even salt spray diffusion.

[0047] The function of the fixing block 120 is to connect the spray liquid pipe 130 and the compressed air pipe 140 as a whole and fix them on the first bracket 110. The fixing block 120 is generally made of corrosion-resistant polypropylene (PP), polytetrafluoroethylene (PTFE), or glass. Using PP or PTFE can effectively prevent the fixing block 120 from being corroded by salt spray testing. At the same time, PP and PTFE materials have strong toughness, which is suitable for scenarios that require frequent changes of experimental positions. The fixing block 120 made of glass also has strong corrosion resistance. In addition, the high hardness of glass makes it difficult to deform and will not be worn by salt spray erosion or temperature changes, thus extending its service life. In addition, the transparency of glass allows the experimenter to directly observe the flow of salt water in the internal spray liquid pipe 130, making it easier to find the location of blockages. Therefore, the fixing block 120 made of glass is suitable for situations where the experimental position is fixed and long-term continuous experiments are required. Similar to the fixing block 120, to prevent corrosion of the spray liquid pipe 130 and the compressed air pipe 140, their materials can also be PP, PTFE, or glass. The fixing block 120 is fixedly connected to the outer wall of the spray liquid pipe 130, and the fixing block 120 is fixedly connected to the outer wall of the L-shaped long side of the compressed air pipe 140. This design allows the spray liquid pipe 130 and the compressed air pipe 140 to be moved or fixed as a whole, which is convenient and quick.

[0048] The function of the first bracket 110 is to fix the spray assembly 100 onto the guide tube 200. The first bracket 110 includes a first fixing part 111, a second fixing part 112, and a first slide rail 113. The first fixing part 111 and the second fixing part 112 can be sleeved and fixed onto the guide tube 200. To achieve this purpose, the first fixing part 111 and the second fixing part 112 are usually set in the form of a clamp, that is, a circular ring with two opposing bolt holes at the end. The inner diameter of the clamp matches the outer diameter of the guide tube 200. The clamp is sleeved on the outer wall of the guide tube 200, and bolts are passed through the two bolt holes and tightened with nuts to achieve a fixed connection between the first fixing part 111 or the second fixing part 112 and the guide tube 200. In particular, in order to make the connection between the first fixing part 111 and the second fixing part 112 and the guide tube 200 more stable and to prevent slippage, anti-slip components are also provided on the inner wall of the clamp, such as adding a layer of anti-slip rubber pad, or directly processing anti-slip patterns on the inner wall of the clamp to increase friction.

[0049] To facilitate the fixing of the fixing block 120 to the first bracket 110, and to allow for adjustment of the fixing height of the fixing block 120 according to experimental requirements, the fixing block 120 includes a first through hole 121 and a first fixing member. One end of the first slide rail 113 is fixedly connected to the bolt hole of the first fixing part 111, and the other end of the first slide rail 113 is fixedly connected to the bolt hole of the second fixing part 112. The first fixing member can pass through the first through hole 121 and the first slide rail 113 to achieve a fixed connection between the fixing block 120 and the first slide rail 113. The first fixing member can slide along the first slide rail 113 to fix the fixing block 120 at different positions on the first slide rail 113. To clamp the fixing block 120 and the first slide rail 113, the first fixing member can be a bolt with a nut. When the threaded rod passes through the first through hole 121 of the fixing block 120 and the first slide rail 113, the nut contacts the fixing block 120. On the back of the first slide rail 113, the nut is tightened. Utilizing the screw effect, the nut and nut generate a clamping force with relative movement, thereby achieving the clamping operation between the fixing block 120 and the first slide rail. When it is necessary to adjust the height of the fixing block 120, the nut can be turned in the opposite direction to move the nut and nut away from each other, thereby loosening the fixing block 120 and the first slide rail. The fixing block 120 can be adjusted to the specified height. Repeating the above operation will re-fix the fixing block 120.

[0050] The above describes the structural features of the spray assembly 100. The following section will describe the structure of the dispersion assembly 300 in detail.

[0051] The function of the dispersion component 300 is to disperse and guide the salt spray overflowing from the guide tube 200. The dispersion assembly 300 includes a disperser 310 and a second support 320. The disperser 310 has a conical or oblique shape. When the atomizing spray device 10 is located at the center of the salt spray chamber or away from the side wall of the salt spray chamber, a conical disperser 310 can be used. When the salt mist is blown from the guide tube 200 to the conical disperser 310, the salt mist can be evenly dispersed in all directions, thus making the salt mist distribution in the salt spray chamber more uniform. When the atomizing spray device 10 is located close to the side wall of the salt spray chamber, an oblique disperser 310 can be used, and the angle between the oblique side and the side wall of the salt spray chamber is an acute angle. The specific angle can be adjusted according to the experimental requirements. When the salt mist is blown from the guide tube 200 to the oblique disperser 310, the salt mist is guided by the oblique disperser 310 to gradually move away from the side wall of the salt spray chamber and blown towards the central area of ​​the salt spray chamber where the sample is placed, so that the sample is always in the salt spray environment, ensuring the stability of the experiment.

[0052] The second bracket 320 includes a third fixing part 321 and fixing rods 322. The third fixing part 321 can be sleeved and fixed on the guide tube 200, and one end of at least two fixing rods 322 is fixedly connected to the third fixing part 321. Similar to the first fixing part 111 and the second fixing part 112, the third fixing part 321 is also fixed in the form of a clamp. The only difference is that the third fixing part 321 is fixedly connected to at least two fixing rods 322. Therefore, the third fixing part 321 can be fixed in the form of an integral clamp or a combination of clamps with the same number of fixing rods 322. Taking the integral clamp as an example, the clamp includes two bolt holes, and the clamp is fastened to the guide tube 200 by a bolt and nut. One end of at least two fixing rods 322 is integrally formed with the clamp or bolted to it. For example, the two fixing rods 322 are distributed at an angle of 180° on the clamp. The advantage of this design is that fewer bolts are needed, making installation easier. Taking the combination of two clamps as an example, there are two fixing rods 322. One end of the fixing rod 322 can be integrally formed with the clamp or bolted. Each clamp is a semi-circular structure, and each clamp has a bolt hole at each end. The two clamps form a circle. The clamp and the guide tube 200 can be fastened by two bolts and two nuts. If the fixing rod 322 also contains bolt holes, the bolt holes of the fixing rod 322 can be aligned with the bolt holes of the clamp and connected and fastened together. The advantage of this design is that it facilitates the connection and fastening of the fixing rod 322.

[0053] To ensure a more stable connection for the disperser 310 and facilitate its movement along the fixed rods 322 for height adjustment, the disperser 310 is fixedly connected to at least two fixed rods 322. Each fixed rod 322 includes a second slide rail 3221, and the disperser 310 includes a second through hole 311 and a second fixing member. The number of second through holes 311 and the number of second fixing members are the same as the number of fixed rods 322. For example, when there are two fixed rods 322, there are also two second through holes 311 and two second fixing members. The second fixing member can pass through the second through hole 311 and the second slide rail 3221 to fix the disperser 310 and the fixed rods 322. The second fixing member can be a bolt and nut assembly, securing the disperser 310 and the fixed rods 322 from both sides of the fixed rods 322. Alternatively, the second fixing member can be a snap-fit ​​connection for quick disassembly and fixation. When the second fixing member is not fixedly connected, it can slide along the second slide rail 3221. When the disperser 310 is moved to a specified height, the second fixing member is then tightened to fix the disperser 310 at different positions on the second slide rail 3221. In some embodiments, to achieve more precise control of the height of the disperser 310, the second slide rail 3221 is also marked with a scale. The scale can be used to adjust to a specified height according to experimental needs, and it also makes it easier to level the disperser 310.

[0054] The above describes the structural features of the dispersion component 300. Next, we will introduce the structure of the recirculation component 400 in detail.

[0055] The function of the reflux assembly 400 is to collect un-atomized brine, or brine condensed on the surfaces of the guide tube 200 and the disperser 310. The reflux assembly 400 includes a reflux pool 410 and a reflux pipe 420. The reflux pool 410 is located directly below the guide tube 200. To facilitate the addition or removal of the atomizing spray device 10, the reflux pool 410 is fixedly connected to the guide tube 200. (See [reference]). Figure 1 The return tank 410 seals the bottom of the guide tube 200, facilitating the addition or removal of the atomizing spray device 10 and adjusting test parameters. In some embodiments, the return tank 410 is a large water collection tray, with the guide tube 200 fixed to the upper part of the water collection tray by a bracket. Multiple atomizing spray devices 10 share one return tank 410, and at least one return pipe 420 is provided as needed. This design facilitates the cleaning of the return tank 410. One end of the return pipe 420 is located inside the return tank 410, and the other end is located outside the return tank 410 to drain the brine from the return tank 410. To prevent impurities from clogging the return pipe 420, the portion of the return pipe 420 located inside the return tank 410 is at least 2cm higher than the lowest point of the return tank 410. This allows the bottom 2cm of the return tank 410 to accommodate deposited impurities, while clear brine flows out from the return pipe 420 (above 2cm) to the outside of the return tank 410. This achieves the purpose of preventing impurities from clogging, reducing maintenance frequency, and extending service life.

[0056] The above describes the overall structural features of the salt spray device 10. During salt spray tests, increasing the number of salt spray devices 10 within the salt spray chamber allows for a more uniform distribution of salt spray across the chamber. Increasing the height of the guide tube 200 allows the salt spray to rise a longer distance, thus reducing its velocity at the outlet of the guide tube 200 under gravity. After diffusion by the disperser 310, the area diffused into the salt spray chamber is smaller, thereby controlling the settling range. Rigorous experimental testing demonstrates more uniform settling. Increasing the diameter of the guide tube 200 widens the fan-shaped area of ​​the sprayed salt spray, similarly reducing its velocity at the outlet of the guide tube 200. After diffusion by the disperser 310, the area diffused into the salt spray chamber is smaller, further controlling the uniformity of settling. Additionally, controlling the opening of the valve on the compressed air pipe 140 controls the gas flow rate at the outlet of the compressed air pipe 140, allowing for direct control of the salt spray spray speed and thus the range of salt spray diffusion, ultimately achieving uniformity in settling.
