Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid transportation, in particular to a defoaming device. BACKGROUND

[0002] In modern industrial production, especially in the electroplating industry, the use of chemical solutions is very common. These chemical solutions play a crucial role in various process flows, such as cleaning, etching, and depositing metal layers, etc. With the acceleration of industrialization, there is an increasing demand for efficient and stable liquid transportation systems. However, in practical applications, due to the excessive speed of the chemical solution, a large number of bubbles are often formed when the solution flows into the tank, which not only affects the quality of the production process, but also increases the processing cost and maintenance frequency.

[0003] To alleviate this problem, existing technical means mainly focus on the following aspects: first, by optimizing the design of the pipeline to reduce bubble generation, such as using straight-through or U-shaped structure; second, adding specific chemical additives to the solution to suppress the formation of foam. These two methods are the most common defoaming measures. Specifically, by changing the shape of the pipeline, the speed of the fluid can be slowed down, thereby reducing the generation of bubbles; while chemical additives can reduce the surface tension of the liquid and prevent foam accumulation. In addition, there are some more advanced physical methods, such as ultrasonic defoaming technology and the application of gas separation devices, but these methods usually require high equipment investment and technical support.

[0004] Although the above methods solve the problem of bubble generation to some extent, there are still obvious deficiencies. First of all, relying solely on the optimization of pipeline shape cannot completely eliminate bubbles, especially at high flow rates, bubbles will still be generated in large quantities. Secondly, although chemical additives are effective, long-term use may cause environmental pollution and equipment corrosion, increasing the cost of production and maintenance. Therefore, there is an urgent need for a more effective defoaming device that can significantly reduce bubble generation without relying on chemical additives, improving production efficiency and product quality. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to provide a defoaming device.

[0006] The above technical purpose of the present application is achieved by the following technical solution: a defoaming device, comprising a pipe body connected to the end of a U-shaped pipeline, a plug is provided at the end of the pipe body away from the U-shaped pipeline, a foam breaker is provided in the pipe body, and a plurality of holes are formed in the hollow wall of the pipe body at the end away from the foam breaker.

[0007] By adopting the technical scheme, the shape of the liquid flow channel is changed through the connection of the U-shaped pipeline and the pipe body. In the process of the liquid entering the pipe body through the U-shaped pipeline, the flow rate of the liquid is appropriately slowed down due to the change of the shape of the flow channel. Based on the principle of fluid mechanics, the kinetic energy of the liquid is reduced by prolonging the flow path of the fluid and changing the flow direction of the fluid, thereby reducing the bubbles generated by high-speed impact and turbulent flow from the source. At the same time, the foam destroyer converts part of the residual kinetic energy of the liquid into heat energy and potential energy through a unique structure and working mechanism, further weakening the dynamic factors of foam formation and greatly reducing the probability of foam formation. The hole design of the pipe body provides an orderly outflow channel for the treated liquid, so that the liquid flows out stably, avoids the secondary foaming phenomenon caused by direct impact, ensures that the liquid flows into the liquid pool slowly and uniformly, and ensures the smooth progress of the subsequent process.

[0008] Optionally, the pipe body is provided with a supplementary core near the pipeline opening of one end of the U-shaped pipeline for connecting the pipe body and the U-shaped pipeline.

[0009] By adopting the technical scheme, the supplementary core can accurately adapt to pipe bodies and U-shaped pipelines of different diameters, and further improve the stability and reliability of the device. Through the precise connection structure, the tight connection between the pipe body and the U-shaped pipeline is ensured, the leakage problem caused by loose connection is prevented, the sealing and stability of the entire system are enhanced, the chemical liquid leakage and environmental hazards caused by leakage are avoided, and the safe and stable operation of the system is ensured.

[0010] Optionally, the pipe body is made of stainless steel.

[0011] By adopting the technical scheme, stainless steel has excellent corrosion resistance, can effectively resist the corrosion of chemical liquid, and ensures that the performance of the device will not be affected by the corrosion and aging of the material during long-term use. Good mechanical strength ensures that the pipe body will not deform or be damaged when subjected to certain pressure and fluid impact, providing reliable physical support for the stable operation of the device. Stainless steel has good processability, which facilitates cutting, welding, drilling and other operations during manufacturing, thereby ensuring the overall stability and reliability of the device, and providing convenience for large-scale production and maintenance of the device.

[0012] Optionally, the plug and the pipe body are integrally formed, and the foam destroyer is arranged on the plug.

[0013] By adopting the above technical scheme, the overall strength and sealing performance of the device are greatly improved. In a high-pressure environment, the integral structure avoids the risk of leakage that may be caused by the connection gap of the components, ensuring the sealing performance of the entire device. At the same time, the foam breaker is arranged on the plug, so that the chemical liquid can directly contact the foam breaker when flowing, and the foam breaker can more effectively convert energy and destroy foam. Through direct contact and action, the kinetic energy of the chemical liquid is effectively reduced, thereby further reducing the generation of foam; the integrated design simplifies the manufacturing process, reduces the number of components, reduces the manufacturing cost, and improves the working efficiency and reliability of the device, so that the structure of the entire device is more compact, and the possible failure points are reduced.

[0014] Optionally, the foam breaker is a floating block made of polytetrafluoroethylene material.

[0015] By adopting the above technical scheme, due to the presence of the floating block, the kinetic energy of the water flow changes when flowing through this area, thereby triggering a series of phenomena that are beneficial to defoaming. When the water flow impacts the floating block, the water flow will produce turbulence and local pressure changes, and this disturbance will break the surface tension of the foam, promoting the rupture of the foam. Moreover, the floating block made of polytetrafluoroethylene material itself has a certain flexibility and will deform slightly under the impact of the water flow, further increasing the contact area and collision opportunities with the foam, thereby improving the defoaming effect. The floating block can move freely in the pipe body according to the speed and direction of the water flow, dynamically defoaming the foam at different positions, enhancing the comprehensiveness and effectiveness of defoaming, providing a flexible and efficient foam breaking method for the entire defoaming device, which helps to stably reduce the generation of foam under different working conditions, ensuring the efficiency and stability of the chemical liquid transmission and use process.

[0016] Optionally, the foam breaker is a cylindrical structure.

[0017] By adopting the above technical solutions, the cylindrical structure has a large surface area, and when the water flow passes through, it can contact more foam, and its surface can be provided with specific textures or structures, such as micro-convex or micro-concave structures, which can generate stronger shear force and friction on the foam under the action of the water flow, thereby more effectively destroying the film structure of the foam and improving the defoaming efficiency. The position of the foam breaker with a cylindrical structure in the pipe body is relatively stable, and under different flow rates and flow conditions of the water flow, it can maintain good balance and stability, avoiding affecting the defoaming effect due to the instability of its own position. At the same time, this structure is easy to manufacture and install, and the surface can be easily functionalized, such as coating a defoaming coating or adding other defoaming auxiliary materials, further improving its defoaming performance, providing a strong guarantee for the efficient and stable operation of the entire defoaming device, thereby improving the quality and stability of the chemical water during transmission and use, and reducing various negative effects caused by foam problems.

[0018] Optionally, the plurality of holes are uniformly distributed along the circumferential direction of the pipe body.

[0019] By adopting the above technical solutions, the uniform outflow of the fluid in the pipe body is ensured, and the phenomenon of too fast or too slow local flow rate caused by uneven distribution of holes is avoided. When the fluid passes through the uniformly distributed holes, a relatively stable flow field can be formed, reducing the turbulence and pressure fluctuations caused by flow rate differences, thereby reducing the possibility of foam generation caused by fluid dynamics instability. The uniformly distributed holes can make the fluid release more balanced in the circumferential direction, and the defoamed fluid can be uniformly discharged from the pipe body, which helps to maintain the fluid dynamics stability of the entire device. In addition, this distribution method is beneficial for cooperation with other components, for example, when used with a foam breaker, the uniformly outflowing fluid can better participate in the defoaming process, avoiding the influence of local fluid concentration or uneven distribution on the defoaming effect. At the same time, this uniform distribution also has the convenience in the manufacturing process, which can utilize standardized processing technology to ensure the spacing and position accuracy between each hole, improving production efficiency and product quality, and providing a reliable structural foundation for the stable operation and efficient defoaming of the defoaming device under different working conditions.

[0020] Optionally, the holes are circular.

[0021] By adopting the above technical scheme, the geometric shape of the circular holes helps to maintain the laminar flow state of the fluid. When the fluid flows through the circular holes, the flow lines are relatively smooth, avoiding the turbulence phenomenon caused by irregular hole shape, thereby reducing the risk of generating new foam due to turbulent flow of the fluid. At the same time, the circular holes can ensure that the flow characteristics of the fluid in all directions are consistent, so that the flow velocity distribution of the fluid through the holes is more uniform, which is conducive to the smooth flow of the fluid and improves the working efficiency of the defoaming device. From the manufacturing point of view, the circle is a common and easy-to-process shape. In the processing process, standard drilling or forming process can be adopted to ensure the size accuracy and surface finish of the holes, which not only reduces the processing cost, but also improves the manufacturing efficiency. Moreover, the edge transition of the circular hole is relatively smooth, reducing the energy loss and local pressure jump of the fluid at the edge of the hole, further optimizing the flow state of the fluid, providing favorable structural conditions for the efficient and stable operation of the entire defoaming device, and improving the overall performance of the device.

[0022] In summary, the present application at least includes the following beneficial effects:

[0023] 1. By connecting a pipe body at the end of the U-shaped pipe and setting a foam breaker in the pipe body, in combination with the holes at one end of the pipe body, a high-efficiency defoaming system is formed. It can significantly reduce the generation of foam in the chemical solution during transmission, improve the adverse effects caused by excessive foam on the production process, and improve the quality and stability of the industrial production process such as electroplating. Among them, the connection of the U-shaped pipe and the pipe changes the shape of the solution flow channel, slows down the flow rate, and reduces the generation of bubbles from the source; the foam breaker effectively treats the foam through various methods (such as kinetic energy conversion, physical blocking, and surface structure destruction); and the holes on the pipe body provide a uniform and stable outlet channel for the treated fluid, avoiding secondary foaming and ensuring the smoothness of the entire fluid transmission process.

[0024] 2. The entire defoaming device does not need to add chemical additives, avoiding the environmental pollution and equipment corrosion problems that may be caused by the use of chemical defoaming agents, providing a more environmentally friendly and economical defoaming solution for industrial production, reducing the treatment cost and maintenance frequency, having good social and economic benefits, and meeting the sustainable development needs of industrial production.

[0030] The application will be further described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] In this embodiment, referring to Figs. 1-3 A defoaming device includes a pipe body 2 connected to the end of a U-shaped pipe 1. The end of the pipe body 2 away from the U-shaped pipe 1 is provided with a plug 3. The pipe body 2 is provided with a foam breaker 4 inside. The pipe wall of the pipe body 2 away from the foam breaker 4 is hollow and provided with a plurality of holes 5. This can effectively reduce the air bubbles formed when the chemical solution flows into the tank, thereby improving the quality of electroplating and production efficiency.

[0033] Specifically, the pipe body 2 is made of stainless steel, which has good corrosion resistance and strength, and is suitable for the transmission of various chemical solutions. Another alternative material is carbon steel, which is less expensive but also has good mechanical properties. The specific choice of material depends on the requirements of the actual application scenario.

[0034] Furthermore, the pipe body 2 is provided with a core 6 near the end of the pipe opening connected to the U-shaped pipe 1, which is used to connect the pipe body 2 and the U-shaped pipe 1. The core 6 ensures that the connection is sealed well and prevents leakage of the chemical solution. The core 6 can be fixed by screwing or welding, and the specific connection method can be flexibly selected according to the site conditions.

[0035] The preferred foam breaker 4 is a float made of polytetrafluoroethylene (PTFE). PTFE has excellent chemical corrosion resistance and low friction coefficient, and is suitable for long-term immersion in chemical solutions. In addition to PTFE, nylon or other high-performance plastics can also be used as alternative materials. These materials all have good wear resistance and chemical resistance, which can prolong the service life of the equipment.

[0036] The foam breaker 4 adopts a cylindrical structure, which can increase the contact area with the chemical solution and more effectively break the air bubbles. If further optimization is needed, the foam breaker 4 can also be designed as a cone or a sphere to adapt to different flow rates and pressures. In addition, the surface of the foam breaker 4 can be processed with uneven textures to enhance the disturbance effect and further reduce the generation of air bubbles.

[0037] The pipe wall of the pipe body 2 far away from the foam breaker 4 is hollow and provided with a plurality of holes 5. The holes 5 are uniformly distributed along the circumferential direction of the pipe body 2, so that the chemical solution can flow out from multiple directions, avoiding excessive local pressure leading to the generation of new bubbles. The shape of the hole 5 can be circular, square or oval, and the specific shape is adjusted according to actual needs. In order to prevent the hole 5 from being easily blocked, a filter screen or barb structure can be installed inside the hole 5 to prevent impurities from entering the hole 5.

[0038] The implementation principle of the embodiment is: by optimizing the structure of the pipe body 2 and the design of the foam breaker 4, the defoaming device can effectively reduce the kinetic energy when the chemical solution flows, thereby greatly reducing the possibility of bubble generation. Specifically, the chemical solution first slows down through the U-shaped pipe 1, then enters the inside of the pipe body 2, is hindered by the foam breaker 4, and the kinetic energy is converted into heat energy and potential energy, and finally flows out smoothly through the hole 5. This process not only reduces the generation of bubbles, but also improves the stability of the chemical solution flowing into the chemical solution pool, significantly improving the electroplating quality. Compared with the traditional pipe optimization and chemical additive method, the present scheme is more environmentally friendly and economically efficient, and has a wide application prospect.

[0039] Embodiment 2

[0040] The difference between the present embodiment and the above-mentioned embodiments is that the material of the foam breaker 4 is changed to nylon instead of polytetrafluoroethylene. The shape of the hole 5 is changed to square instead of circular.

[0041] Specifically, the foam breaker 4 is made of nylon material. Nylon has high mechanical strength and good chemical resistance, and is especially suitable for application in high temperature environment. Compared with polytetrafluoroethylene, nylon has lower cost and is more suitable for large-scale production and application.

[0042] The shape of the hole 5 is changed to square, which can increase the effective flow area of the hole 5 and make the chemical solution flow out more smoothly. The edges of the square hole 5 can be chamfered to prevent sharp edges from cutting the soft material of the chemical solution pipeline. In addition, the layout of the square hole 5 is still uniformly distributed, ensuring the pressure balance when the chemical solution flows out from all directions.

[0043] The implementation principle of the present embodiment is: by changing the material of the foam breaker 4 and the shape of the hole 5, the present embodiment not only maintains the original defoaming effect, but also further reduces the manufacturing cost and improves the application range of the equipment. The foam breaker 4 made of nylon material not only has strong durability, but also has low price, which is suitable for various industrial scenes. The design of the square hole 5 enhances the uniformity and stability of the chemical solution flow, which helps to improve the reliability of the whole system. Overall, the present embodiment realizes higher cost performance on the basis of maintaining technological innovation, and has better market competitiveness.

[0044] Embodiment 3

[0045] The difference between this embodiment and the above embodiments is that the foam breaker 4 adopts a conical structure instead of a cylinder. The core 6 is fixed by welding instead of threaded connection.

[0046] Specifically, the foam breaker 4 adopts a conical structure. The conical structure can better guide the upward flow of the liquid medicine, increase the contact area with the liquid medicine, and more effectively break the bubbles. The tip of the conical foam breaker 4 faces the direction of the liquid medicine inflow, and the wide part at the bottom acts as a buffer to reduce the impact force of the liquid medicine. This design is particularly suitable for defoaming requirements in high flow rate conditions.

[0047] The core 6 is fixed by welding. Welding is more secure and reliable than threaded connection, suitable for high pressure or high temperature working environment. The welding seam can be polished to ensure that the connection part is smooth and flat, and there will be no dead angle to cause liquid medicine residue. In addition, the welding method can also improve the sealing of the overall structure to prevent liquid medicine leakage.

[0048] The implementation principle of this embodiment is: by improving the shape of the foam breaker 4 and the fixing method of the core 6, this embodiment performs well in high flow rate and harsh environment. The design of the conical foam breaker 4 greatly improves the bubble breaking effect, especially in high flow rate conditions, it can still effectively reduce bubble generation. The core 6 fixed by welding ensures the firmness and sealing of the connection part, prolongs the service life of the equipment. In summary, this embodiment performs better in complex working conditions and has high practical value.

[0049] Embodiment 4

[0050] The difference between this embodiment and the above embodiments is that the surface of the foam breaker 4 is processed with uneven texture to enhance the disturbance effect. The filter screen is installed inside the hole 5 to prevent impurities from entering the hole 5.

[0051] Specifically, the surface of the foam breaker 4 is processed with uneven texture. Such design can increase the contact area between the liquid medicine and the surface of the foam breaker 4, further disturbing the formation of bubbles. The uneven texture can be prepared by laser engraving or mechanical processing, and the specific pattern can be optimized according to the experimental results. This design is particularly suitable for liquid medicine containing solid particles, which can effectively prevent particle accumulation and maintain the long-term operation of the foam breaker 4.

[0052] A filter screen is installed inside the hole 5. The filter screen can effectively intercept large particles of impurities, preventing them from entering the hole 5 and causing blockage. The material of the filter screen can be selected from stainless steel mesh or nylon mesh, which has good corrosion resistance and filtering effect. The mesh number of the filter screen can be adjusted according to actual needs. Generally, it is recommended to use fine filter screen with 80-100 mesh, which can effectively filter impurities without affecting the normal flow of the medicine.

[0053] The implementation principle of the embodiment is that by special treatment of the surface of the foam destroyer 4 and installation of a filter screen inside the hole 5, the embodiment not only prevents the generation of bubbles, but also improves the stability and reliability of the system. The uneven texture design greatly increases the contact opportunities between the medicine and the foam destroyer 4, making it easier to be decomposed. The presence of the filter screen ensures that the hole 5 is unobstructed, avoiding failure caused by impurities blockage. In general, the optimization of details in the embodiment makes it perform better in practical application, and has strong practical operation significance.

[0054] The embodiments of the specific implementation are the preferred embodiments of the present application, but do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
