Description

Technical Field

[0001] This utility model belongs to the field of chemical pipeline purging technology, specifically relating to a gas purging mechanism with noise reduction function. Background Technology

[0002] Pipeline purging technology plays a crucial role in chemical production processes. In chemical production, pipeline systems are used to transport various chemical substances, which may leave residues inside the pipelines, including flammable gases and hazardous materials. If not removed promptly, these residual chemicals can trigger potential chemical reactions, leading to pipeline corrosion and even serious safety hazards such as explosions and leaks, threatening human lives and company property.

[0003] Effective chemical pipeline purging operations offer numerous significant benefits, including improved production efficiency, ensuring unobstructed pipeline flow and smoother chemical production processes; extended pipeline lifespan, reducing pipeline damage and replacement costs due to residues; reduced environmental pollution, preventing the leakage of hazardous substances into the environment; and significantly reduced operational risks, ensuring the safety of production personnel.

[0004] Currently, existing pipeline purging technology has significant shortcomings in terms of gas supply. Specifically, the unstable gas supply leads to inconsistent purging effects. When the gas supply is insufficient, it may not be able to completely remove harmful substances from the pipeline, leaving harmful substances in the pipeline and greatly increasing safety hazards. Moreover, the existing gas supply system lacks a stable replenishment mechanism, which is prone to gas supply interruptions, seriously affecting the continuity and efficiency of purging, causing frequent interruptions in the purging process, and increasing production time and costs.

[0005] Furthermore, the suboptimal airflow path design of the purging device is a prominent problem in existing technology. Significant energy loss occurs during gas transmission, directly reducing purging efficiency and prolonging purging time. This energy loss necessitates the consumption of more gas to complete the purging task, increasing production costs and impacting efficiency, thus extending the chemical production cycle. Finally, existing noise reduction measures are relatively simplistic and inadequate for dealing with complex and varied noise sources. They fail to effectively reduce high-frequency noise, and the noise generated during gas purging in chemical pipelines can damage the hearing of operators, impacting the working environment and their health. Utility Model Content

[0006] The purpose of this invention is to provide a gas purging mechanism with noise reduction function to solve one of the defects in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A gas purging mechanism with noise reduction function includes:

[0009] The gas supply device has a purging device connected to one end and a gas replenishment device connected to the other end.

[0010] A noise reduction device is provided on the blowing device. The noise reduction device includes an elastic buffer layer, a sound absorption unit, a noise reduction unit, and a sound insulation unit. The elastic buffer layer and the sound absorption unit are provided on the inner side of the blowing device, and the noise reduction unit and the sound insulation unit are provided on the outer side of the blowing device.

[0011] A control device is installed on the gas supply device and electrically connected to the gas supply device and the gas replenishment device.

[0012] Furthermore, the purging device includes an air outlet pipe, the end of which is connected to a first quick connector, the end of which is fitted with a connecting pipe, and the end of which is provided with a second quick connector.

[0013] The connecting pipe is equipped with an airflow dispersion component; wherein, the elastic buffer layer and the sound absorption unit are disposed on the inner side of the connecting pipe, and the sound-absorbing unit and the sound insulation unit are disposed on the outer side of the connecting pipe.

[0014] Furthermore, the sound-absorbing unit is a sound-absorbing layer, which is wrapped around the outside of the elastic buffer layer and is attached to the inner wall of the connecting pipe.

[0015] Furthermore, the silencing unit is a silencing layer, the sound insulation unit is a sound insulation layer, the silencing layer is wrapped around the outside of the connecting pipe, and the sound insulation layer is wrapped around the outside of the silencing layer.

[0016] Furthermore, a corrosion-resistant layer is wrapped around the outside of the sound insulation layer.

[0017] Furthermore, the airflow dispersion component includes an airflow dispersion plate disposed in a connecting pipe, and the airflow dispersion plate has a plurality of dispersion holes arranged around its circumference.

[0018] Furthermore, the gas supply device includes a working box, which contains a gas storage tank, a gas pump, and an air inlet pipe. The gas storage tank and the gas pump are connected through the air inlet pipe.

[0019] Furthermore, a door is rotatably connected to the work box, and the door is provided with a handle;

[0020] The bottom of the work box is equipped with a base, and the base is equipped with wheels and a handle.

[0021] Furthermore, the gas replenishment device is a gas replenishment pipe.

[0022] Furthermore, the purging device is equipped with a solenoid valve.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. It can monitor the gas supply in real time. When the gas supply device is insufficient, the gas replenishment device can replenish the gas in time to ensure a stable gas supply during the purging process. A stable gas supply can ensure the consistency of the purging effect and avoid the residue of harmful substances in the pipeline due to insufficient gas, thereby effectively reducing safety hazards and improving the safety of chemical production. The elastic buffer layer can buffer the vibration noise generated by gas impact, the sound absorption unit can absorb some noise energy, the silencing unit can further eliminate noise of specific frequencies, and the sound insulation unit can prevent noise from spreading outward, forming an effective noise reduction barrier.

[0025] 2. The airflow dispersion component enables the gas entering the pipeline to be dispersed more evenly. During the purging process, the uniform airflow can cover the entire pipeline cross-section, avoiding the phenomenon of airflow concentration or dead corners, thereby improving the purging effect and ensuring that the residue in the pipeline can be removed more thoroughly. The synergistic effect of the inner and outer noise reduction components forms a comprehensive noise reduction system, effectively reducing the noise pollution generated during the purging process, improving the environmental performance of the equipment and the comfort of the operators.

[0026] 3. The sound-absorbing layer is wrapped around the outside of the elastic buffer layer, so that the two can work together to reduce noise, thereby effectively reducing the noise level inside the purging device.

[0027] 4. The sound-absorbing layer is directly wrapped around the outside of the connecting pipe, which can effectively eliminate the noise generated by the gas flow inside the pipe.

[0028] 5. A corrosion-resistant layer is wrapped around the outside of the sound insulation layer, effectively preventing corrosive substances from contacting the sound insulation layer, thus protecting it from corrosion damage and extending its service life. At the same time, it also indirectly protects the internal sound-absorbing layer and connecting pipes, preventing them from being affected by corrosion due to damage to the sound insulation layer.

[0029] 6. An airflow dispersion plate is installed in the connecting pipe, with multiple dispersion holes around its circumference. This allows the gas entering the pipe to be dispersed more evenly. During the purging process, the gas is ejected from the dispersion holes in multiple directions and angles, avoiding concentrated gas impact on a certain area. This ensures that the entire pipe cross-section is effectively purged by the gas. The uniform airflow distribution helps to improve the purging effect, reduce purging dead zones, and ensure that the residue in the pipe can be removed more thoroughly. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0039] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0041] This embodiment provides a gas purging mechanism with noise reduction function. The following is a further detailed description of the present invention with reference to the accompanying drawings:

[0042] like Figures 1-4 As shown, a gas purging mechanism with noise reduction function includes a gas supply device, one end of which is connected to the purging device and the other end of which is connected to the gas replenishment device; a noise reduction device is disposed on the purging device, and the noise reduction device includes an elastic buffer layer 12, a sound absorption unit, a sound silencing unit and a sound insulation unit, the elastic buffer layer 12 and the sound absorption unit are disposed inside the purging device, and the sound silencing unit and the sound insulation unit are disposed outside the purging device; a control device is disposed on the gas supply device and electrically connected to the gas supply device and the gas replenishment device.

[0043] In the above structure, one end of the gas supply device is connected to the purging device, and the other end is connected to the gas replenishment device. The control device is electrically connected to both the gas supply device and the gas replenishment device, enabling real-time monitoring of the gas supply. When the gas supply device experiences insufficient gas supply, the gas replenishment device can promptly replenish the gas, ensuring a stable gas supply during the purging process. Moreover, a stable gas supply ensures consistent purging results and prevents the residue of harmful substances in the pipeline due to insufficient gas, thereby effectively reducing safety hazards and improving the safety of chemical production.

[0044] Secondly, the presence of the gas replenishment device avoids the problem of interrupted gas supply affecting the continuity of purging in the existing technology. The purging process can be carried out continuously and stably, reducing the production time and cost increased due to interruption. At the same time, the stable gas supply also improves the purging efficiency, enabling the purging task to be completed in a shorter time, shortening the chemical production cycle and improving production efficiency.

[0045] Furthermore, a noise reduction device is installed on the purging device, including an elastic buffer layer 12, a sound-absorbing unit, a noise-absorbing unit, and a sound-insulating unit, respectively located on the inner and outer sides of the purging device. This comprehensive noise reduction design can address noise from multiple angles. The elastic buffer layer 12 can buffer the vibration noise generated by gas impact, the sound-absorbing unit can absorb some noise energy, the noise-absorbing unit can further eliminate noise of specific frequencies, and the sound-insulating unit can prevent noise from propagating outward, forming an effective noise reduction barrier. Compared with the single noise reduction measures in existing technologies, this diversified noise reduction measure can cope with complex and varied noise sources. Different noise units deal with different noise types and frequencies, especially effectively reducing high-frequency noise. This allows for better protection of the operator's hearing during the gas purging process in chemical pipelines, improves the working environment, protects the operator's health, and enhances work comfort and safety. Finally, a control device is installed on the gas supply device and electrically connected to the gas supply and replenishment devices, realizing intelligent control of the entire gas purging mechanism. The control device can monitor and adjust the gas supply parameters in real time, and precisely control the gas flow and pressure according to the purging requirements, ensuring the efficient and stable operation of the purging process.

[0046] Furthermore, the purging device includes an air outlet pipe 5, with a first quick connector 6 connected to the end of the air outlet pipe 5. A connecting pipe 7 is installed at the end of the first quick connector 6, and a second quick connector 8 is provided at the end of the connecting pipe 7. An airflow dispersion component is provided inside the connecting pipe 7. The elastic buffer layer 12 and the sound-absorbing unit are disposed inside the connecting pipe 7, while the silencing unit and the sound insulation unit are disposed outside the connecting pipe 7. Specifically, the sound-absorbing unit is a sound-absorbing layer 13, which is wrapped around the outside of the elastic buffer layer 12 and adheres to the inner wall of the connecting pipe 7. The silencing unit is a silencing layer 14, and the sound insulation unit is a sound insulation layer 15, which is wrapped around the outside of the connecting pipe 7 and the sound insulation layer 15 is wrapped around the outside of the silencing layer 14.

[0047] In the above structure, the outlet pipe 5 of the purging device is connected to a first quick connector 6, the end of the first quick connector 6 is fitted with a connecting pipe 7, and the end of the connecting pipe 7 is equipped with a second quick connector 8. This quick-connect structure makes it very convenient to connect and disassemble the purging device with other components. In actual operation, connection or disassembly can be completed quickly without the use of complicated tools and lengthy operations, greatly improving the efficiency of installation and disassembly and reducing the time cost of equipment maintenance and component replacement.

[0048] An airflow dispersion component is installed inside the connecting pipe 7, which enables the gas entering the pipe to be dispersed more evenly. During the purging process, the uniform airflow can cover the entire pipe cross-section, avoiding the phenomenon of airflow concentration or dead corners, thereby improving the purging effect and ensuring that the residues in the pipe can be removed more thoroughly.

[0049] Because the airflow dispersion component makes the gas flow more smoothly, it reduces eddies and turbulence in the gas within the pipe, thereby reducing energy loss. This means that less gas energy can be consumed to achieve the same purging effect during the purging process, improving energy efficiency and reducing production costs.

[0050] The elastic buffer layer 12 and the sound-absorbing unit are located inside the connecting pipe 7, which can directly process the noise generated by the gas flow. The elastic buffer layer 12 can buffer the vibration noise generated by the gas impact, and the sound-absorbing unit can absorb some of the noise energy, thereby reducing the generation and propagation of noise from the source and effectively reducing the noise level inside the purging device.

[0051] The sound-absorbing layer 13 is wrapped around the outside of the elastic buffer layer 12. The two layers work together to reduce noise. The elastic buffer layer 12 first buffers the vibrations generated by gas impact, reducing the source of noise. The sound-absorbing layer 13 further absorbs the remaining noise energy after the buffer layer treatment. Through its porous structure or special material structure, it converts sound energy into heat energy and other forms of energy, effectively reducing the noise level inside the purging device. Furthermore, the combination of the elastic buffer layer 12 and the sound-absorbing layer 13 can broaden the frequency range of sound absorption. The elastic buffer layer 12 may have a good buffering effect on vibration noise at certain specific frequencies, while the sound-absorbing layer 13 can absorb noise over a wider frequency range. This synergistic effect allows the entire noise reduction system to cope with complex and varied noise sources, improving the comprehensiveness and effectiveness of noise reduction. Secondly, the sound-absorbing layer 13 is in close contact with the inner wall of the connecting pipe 7, which ensures that the sound-absorbing layer 13 is in full contact with the path of noise propagation. This close fit design allows the noise to be absorbed more directly by the sound-absorbing layer 13 during propagation, reducing the reflection and scattering of noise between the inner wall of the pipe and the sound-absorbing layer 13, thereby improving the sound absorption efficiency.

[0052] In this embodiment, a corrosion-resistant layer 16 is wrapped around the outer side of the sound insulation layer 15, which can effectively prevent corrosive substances from contacting the sound insulation layer 15, thereby protecting the sound insulation layer 15 from corrosion damage and extending its service life. At the same time, it also indirectly protects the internal sound-absorbing layer 14 and connecting pipe 7, preventing them from being affected by corrosion due to damage to the sound insulation layer 15.

[0053] Furthermore, the airflow dispersion component includes an airflow dispersion plate 9, which is disposed within the connecting pipe 7. Multiple dispersion holes 10 are arranged around the circumference of the airflow dispersion plate 9, enabling more uniform dispersion of the gas entering the connecting pipe 7. During the purging process, the gas is ejected through the dispersion holes 10 in multiple directions and angles, preventing concentrated gas impact on a specific area. This ensures that the entire pipe cross-section is effectively purged. The uniform airflow distribution helps improve the purging effect, reduces purging dead zones, and ensures that residues within the pipe are more thoroughly removed. Simultaneously, the multiple dispersion holes 10 increase the contact area between the gas and the inner wall of the pipe, allowing the gas to more comprehensively cover the inside of the pipe. In the same amount of time, more gas can act on the inner wall of the pipe, improving purging efficiency. At the same time, the uniform airflow distribution also reduces the flow resistance of the gas within the pipe, allowing the gas to flow more smoothly and further increasing the purging speed.

[0054] In this embodiment, the gas supply device includes a working box 1, which contains a gas storage tank 2, a gas pump 3, and an air inlet pipe 4. The gas storage tank 2 and the gas pump 3 are connected via the air inlet pipe 4. A door 19 is rotatably connected to the working box 1, and a handle 20 is provided on the door 19. A base 21 is provided at the bottom of the working box 1, and a wheel 22 and a handle 23 are provided on the base 21. By configuring the gas storage tank 2 and the gas pump 3 inside the working box 1, and effectively connecting the gas pump 3 to the gas storage tank 2 and the air outlet pipe 5, a stable gas supply and efficient transmission are achieved. The gas pump 3 is fixed to the bottom of the working box 1 to ensure stability during operation. The connection between the air inlet pipe 4 and the inner wall of the gas storage tank 2 optimizes the gas flow path and reduces energy loss.

[0055] The exhaust pipe 5 is connected to the connecting pipe 7 via the first quick connector 6, which simplifies the installation and maintenance process of the equipment, improves the convenience of operation, reduces turbulence and noise sources in the airflow, thereby effectively reducing the noise level during the purging process, significantly improving the working environment, enhancing the reliability and durability of the system, and ensuring the efficient and stable operation of the gas purging process.

[0056] A second quick connector 8 is fixedly connected to one end of the connecting pipe 7, and an airflow dispersion plate 9 is fixedly connected inside the connecting pipe 7. Dispersion holes 10 are opened on the outer surface of the airflow dispersion plate 9.

[0057] By using the second quick connector 8 on the connecting pipe 7 and the internally installed airflow dispersion plate 9, the gas is more evenly distributed during transmission, reducing energy loss caused by concentrated airflow.

[0058] An air supply pipe 11 is fixedly connected to the upper surface of the air storage tank 2. One end of the air supply pipe 11 penetrates the upper surface of the working box 1, and a solenoid valve 18 is installed on the outer wall of the air outlet pipe 5.

[0059] In this embodiment, the gas replenishment device is a gas replenishment pipe 11, and the purging device is equipped with a solenoid valve 18. The design of the gas replenishment pipe 11 ensures continuous gas replenishment in the gas storage tank 2, maintaining the stability of the gas supply. The application of the solenoid valve 18 enables precise control of the airflow, improving the flexibility and response speed of the purging process. A sound-absorbing layer 13 is provided on the inner wall of the connecting pipe 7, an elastic buffer layer 12 is provided on the outer surface of the sound-absorbing layer 13, a sound-absorbing layer 14 is provided on the outer wall of the connecting pipe 7, a sound-insulating layer 15 is provided on the outer surface of the sound-absorbing layer 14, and a corrosion-resistant layer 16 is provided on the outer surface of the sound-insulating layer 15. The combination of the sound-absorbing layer 13 and the elastic buffer layer 12 effectively absorbs and buffers noise fluctuations in the airflow, further reducing the overall noise level. The multiple protections of the sound-absorbing layer 14, the sound-insulating layer 15, and the corrosion-resistant layer 16 not only enhance the noise suppression capability of the equipment but also extend the service life of the device, adapting it to harsh working environments.

[0060] In this embodiment, the control device is a control panel 17. The control panel 17 is fixedly connected to one side of the outer wall of the work box 1. The outer wall of the work box 1 is connected to a door 19. The outer wall of the door 19 is fixedly connected to a handle 20. The lower surface of the work box 1 is fixedly connected to a base 21. The four corners of the lower surface of the base 21 are fixedly connected to a traveling wheel 22. The rear outer wall of the work box 1 is fixedly connected to a handle 23.

[0061] The integrated control panel 17 simplifies the operation process. The design of the wheels 22 and handle 23 improves the ease of movement and efficiency of installation and maintenance. The operator compresses the gas and delivers it to the outlet pipe 5 via the connected air pump 3. The airflow passes through the airflow dispersion plate 9 in the connecting pipe 7, is evenly distributed, and then released through the dispersion holes 10, ensuring comprehensive purging of the gas in the pipe. The air supply pipe 11 ensures continuous replenishment of the gas in the air tank 2, maintaining the stability of the purging process. The adjustment of the solenoid valve 18 enables precise control of the airflow, making the purging process more flexible and efficient.

[0062] The sound-absorbing layer 13 and the elastic buffer layer 12 inside the connecting pipe 7 work together to absorb and buffer noise fluctuations generated by airflow, significantly reducing the overall noise level. At the same time, the external sound-absorbing layer 14, sound-insulating layer 15, and corrosion-resistant layer 16 provide multiple layers of protection, further suppressing noise and improving the durability of the device.

[0063] The control panel 17 is integrated into the outer wall of the work box 1 for easy operation and monitoring. The design of the wheels 22 and handle 23 improves the ease of movement of the equipment and the efficiency of installation and maintenance. The overall airflow path is optimized to ensure efficient, stable and low-noise operation of the gas purging process, improve the working environment, and protect the health and safety of operators.

[0064] Place the work box 1 near the chemical pipeline requiring gas purging. Use the wheels 22 and handle 23 to move the equipment to the designated position, ensuring the outlet pipe 5 can be smoothly connected to the pipeline inlet. Connect the outlet pipe 5 to the connecting pipe 7 via the first quick connector 6, and connect it to the purging inlet of the chemical pipeline via the second quick connector 8, ensuring a secure connection. Check the gas level in the gas storage tank 2 to ensure sufficient gas for purging. If necessary, supplement gas via the gas replenishment pipe 11 to ensure a continuous gas supply. Open the control panel 17 and start the air pump 3. The gas in the gas storage tank 2 enters the air pump 3 through the inlet pipe 4 for compression. The compressed gas is delivered to the connecting pipe 7 through the outlet pipe 5, and after being evenly distributed by the airflow dispersion plate 9, it enters the pipeline system being purged through the dispersion holes 10. Monitor the airflow parameters and equipment operating status in real time through the control panel 17, and adjust the speed of the air pump 3 and the opening of the solenoid valve 18 as needed to ensure an efficient and stable purging process. During the purging process, the sound-absorbing layer 13 and the elastic buffer layer 12 absorb and buffer noise fluctuations, while the external sound-absorbing layer 14 and sound-insulating layer 15 further reduce noise. After the purging task is completed, the control panel 17 is turned off, and the air pump 3 is stopped. The equipment can be moved using the wheels 22 and the handle 23 for easy installation or maintenance. The entire process is simple and efficient, ensuring the cleanliness and safety of the pipeline interior while providing a low-noise working environment.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit its protection scope. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading this utility model, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the utility model, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the utility model.
