[0001] This utility model relates to the field of chemical pipeline technology, specifically a safety cover for chemical pipelines with a layered heat insulation buffer layer. Background Technology

[0002] Chemical pipelines are core facilities in chemical production plants, acting like the factory's "circulatory system." Composed of steel pipes, fittings, and valves, they are manufactured strictly according to process requirements. These pipelines typically withstand high temperatures and pressures and possess corrosion and wear resistance. Material selection and manufacturing processes are extremely rigorous. The design, installation, and maintenance of chemical pipelines directly affect production continuity, energy efficiency, and inherent safety. They are crucial for preventing leaks, fires, explosions, and other accidents, holding a vital position in modern chemical enterprises. Chemical pipelines transport toxic, harmful, and corrosive media and are widely used in industries such as pharmaceuticals, metallurgy, environmental protection, water supply and drainage, and petroleum. In recent years, the demand for chemical pipelines has been increasing, leading to a corresponding rise in the demand for tools and equipment used in their production.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: although they can protect chemical pipelines, their heat insulation performance is singular, resulting in limited heat insulation effect, which in turn leads to large heat loss or insufficient ability to prevent the intrusion of external heat sources. Therefore, we propose a chemical pipeline safety protection cover with a layered heat insulation buffer layer to solve the above-mentioned problems. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a safety cover for chemical pipelines with a layered heat insulation buffer layer, including a protective component, wherein the protective component is used to protect the chemical pipeline;

[0014] Beneficial effects

[0015] This utility model provides a safety cover for chemical pipelines with a layered heat insulation buffer layer. Compared with the prior art, it has the following advantages:

[0016] This safety cover for chemical pipelines with layered heat insulation and buffer layers works by first fixing the protective components to the outside of the chemical pipeline, and then fixing two layered heat insulation and buffer components inside the protective components. Since the two inner lining components are placed inside the two layered heat insulation and buffer components, they fit tightly against the chemical pipeline, thus providing a buffering effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 4This utility model provides a technical solution: a safety cover for chemical pipelines with a layered heat insulation buffer layer, including a protective component 1 for protecting the chemical pipeline; two layered heat insulation buffer components 2, which are disposed inside the protective component 1 and used to provide heat insulation and buffering for the chemical pipeline; and two inner lining components 3, which are disposed inside the two layered heat insulation buffer components 2 and used to provide initial buffering for the chemical pipeline.

[0024] When safety protection is required for chemical pipelines, the protective component 1 is first fixedly connected to the outside of the chemical pipeline. Then, two layered heat insulation buffer components 2 are fixedly connected to the inner cavity of the protective component 1. Since the two inner lining components 3 are respectively placed inside the two layered heat insulation buffer components 2, the two inner lining components 3 can fit tightly against the chemical pipeline, thereby enabling the inner lining components 3 to buffer the chemical pipeline. This allows the layered heat insulation buffer components 2 to effectively block heat and improve the buffering effect, protecting the chemical pipeline from damage. Then, through the protective component 1, it can resist external physical damage, thus providing safety protection for the chemical pipeline.

[0025] See Figure 1 , Figure 2 The protective component 1 includes a first arc-shaped cover 11, and a second arc-shaped cover 12 symmetrically positioned on the first arc-shaped cover 11. Limiting grooves 13 are provided on the upper and lower outer sides of both the first arc-shaped cover 11 and the second arc-shaped cover 12. Mounting seats 14 are provided on the upper and lower sides of both the first arc-shaped cover 11 and the second arc-shaped cover 12. Locking devices 15 are provided on one side of each of the two mounting seats 14. Locking bands 16 are surrounded around the outer walls of the first arc-shaped cover 11 and the second arc-shaped cover 12. There are two locking bands 16, which are symmetrically distributed. The two ends of the two locking bands 16 are connected and tensioned by locking devices 15. Sealing strips 17 are provided at the joint of the first arc-shaped cover 11 and the second arc-shaped cover 12. The locking bands 16 are made of high-strength stainless steel strips, and the locking devices 15 are ratchet locking devices. The mating surfaces of the first arc-shaped cover 11 and the second arc-shaped cover 12 are connected by tenons or steps.

[0026] The first arc-shaped cover 11 in the protective assembly 1 can be placed on one side of the chemical pipeline and also provides an installation base for the second arc-shaped cover 12. Limiting grooves 13 are provided on the upper and lower outer sides of both the first and second arc-shaped covers 11 and 12, and mounting seats 14 are fixedly connected to the upper and lower sides of both the first and second arc-shaped covers 11 and 12. Locking devices 15 are fixedly connected to one side of each mounting seat 14, and two locking bands 16 surround the outer walls of the first and second arc-shaped covers 11 and 12, allowing the two locking bands 16 to be locked at both ends. The device 15 is connected and tensioned, thereby fixing the first arc-shaped cover 11 and the second arc-shaped cover 12 onto the chemical pipeline, so as to provide tight protection for the chemical pipeline and prevent damage to the pipeline from external factors. Since sealing strips 17 are fixedly connected at the joint of the first arc-shaped cover 11 and the second arc-shaped cover 12, and the locking band 16 is a high-strength stainless steel band, and the locking device 15 is a ratchet locking device, and the mating surfaces of the first arc-shaped cover 11 and the second arc-shaped cover 12 are connected by tenons or steps, the first arc-shaped cover 11 and the second arc-shaped cover 12 can be tightly bound to the chemical pipeline. The connection between the two arc-shaped covers 12 is tighter and more secure, which allows the sealing strip 17 to effectively prevent leakage of the medium in the chemical pipeline, thus achieving a good sealing effect. High-strength stainless steel strips provide high strength and corrosion resistance, enabling them to withstand greater tensile forces and ensuring that they will not loosen or break during long-term use. A ratchet lock allows for quick and accurate adjustment of the tension of the locking band 16, further securing the protective component 1 to the chemical pipeline. The tenon or step connection enhances the connection stability between the first arc-shaped cover 11 and the second arc-shaped cover 12, improving the protective effect. Since both the first arc-shaped cover 11 and the second arc-shaped cover 12 are covered with 304 stainless steel, they effectively resist external physical impacts and chemical corrosion, extending the service life of the protective covers. Furthermore, the 304 stainless steel material has excellent high-temperature resistance, allowing the chemical pipeline to maintain structural stability and integrity even in high-temperature environments, preventing deformation or damage due to high temperatures and ensuring the safe operation of the chemical pipeline.

[0027] See Figure 1 , Figure 3 The layered heat insulation and buffer assembly 2 includes a first aluminum foil layer 21, which is disposed in the inner cavity of the first arc-shaped cover 11. A first sealed silicone mesh layer 22 is disposed inside the first aluminum foil layer 21. An aerogel felt layer 23 is disposed inside the first sealed silicone mesh layer 22. A second sealed silicone mesh layer 24 is disposed inside the aerogel felt layer 23. A second aluminum foil layer 25 is disposed inside the second sealed silicone mesh layer 24. The inner side of the second aluminum foil layer 25 is connected to the inner lining assembly 3.

[0028] The first aluminum foil layer 21 in the layered heat insulation buffer assembly 2 can be fixedly connected to the inner cavities of the first arc-shaped cover 11 and the second arc-shaped cover 12, and also provides an installation base for the first sealed silicone mesh layer 22. Since an aerogel felt layer 23 is fixedly connected to the inner side of the first sealed silicone mesh layer 22, and a second sealed silicone mesh layer 24 is fixedly connected to the inner side of the aerogel felt layer 23, and a second aluminum foil layer 25 is fixedly connected to the second sealed silicone mesh layer 24, with the inner side of the second aluminum foil layer 25 connected to the inner lining assembly 3, it can effectively reflect external heat. This reduces heat transfer into the chemical pipeline, thus mitigating the impact of external environmental factors on the pipeline's internal temperature. The first sealed silicone mesh layer 22, with its good elasticity and sealing properties, fills the tiny gaps between the first aluminum foil layer 21 and the aerogel felt layer 23, enhancing the insulation effect and providing a buffering effect to reduce the impact of external shocks on the pipeline. The aerogel felt layer 23, being a highly efficient insulation material with extremely low thermal conductivity, significantly hinders heat conduction, thereby ensuring the safety of the pipeline. The chemical pipeline maintains a stable temperature under both high and low temperature conditions, preventing damage or performance degradation caused by temperature changes and ensuring its safety. The first aluminum foil layer 21 and the second aluminum foil layer 25 not only provide support but also effectively reflect external heat and reduce heat transfer into the pipeline. The unique mesh structure of the first and second sealed silicone mesh layers 22 and 24 increases the heat conduction path, enhancing insulation. The aerogel felt layer 23 has extremely low thermal conductivity, reducing heat exchange between the inside and outside of the pipeline. This ensures the chemical pipeline maintains a stable temperature under both high and low temperature conditions, preventing damage or performance degradation caused by temperature changes and ensuring its safety. The second sealed silicone mesh layer 24 and the second aluminum foil layer 25 enhance insulation and buffering performance, allowing the second aluminum foil layer 25 to also reflect heat, forming a double insulation barrier in conjunction with the first aluminum foil layer 21 for better protection of the chemical pipeline.

[0029] See Figure 1 , Figure 4 The inner lining component 3 includes an expanded graphite felt layer 31, which is disposed inside the second aluminum foil layer 25. A flexible ceramic fiber cloth layer 33 is disposed inside the expanded graphite felt layer 31. A leak detection sensor 32 is integrated inside the expanded graphite felt layer 31. The leak detection sensor 32 is used to monitor the possible leaks in the chemical pipeline in real time.

[0030] The expanded graphite felt layer 31 in the inner lining assembly 3 can be fixedly connected to the inner side of the second aluminum foil layer 25, and can also provide an installation base for the flexible ceramic fiber cloth layer 33. Since the expanded graphite felt layer 31 integrates a leak detection sensor 32, and the flexible ceramic fiber cloth layer 33 has good high temperature resistance and corrosion resistance, it can withstand the erosion of high temperature and corrosive media, thereby protecting the expanded graphite felt layer 31 and leak detection sensor 32 from damage, so as to improve the reliability and stability of the safety protection cover for chemical pipelines. Through the leak detection sensor 32, it is possible to detect whether a leak has occurred in the chemical pipeline. When a leak occurs in the pipeline, it can quickly detect and issue an alarm signal so that the staff can take timely measures to deal with it.

[0031] When safety protection is required for chemical pipelines during operation, the protective component 1 is first fixedly connected to the outside of the chemical pipeline. Then, two layered heat insulation buffer components 2 are fixedly connected to the inner cavity of the protective component 1. Since the two inner lining components 3 are respectively placed inside the two layered heat insulation buffer components 2, the two inner lining components 3 can fit tightly against the chemical pipeline, thereby enabling the inner lining components 3 to buffer the chemical pipeline. This allows the layered heat insulation buffer components 2 to effectively block heat and improve the buffering effect, protecting the chemical pipeline from damage. Then, through the protective component 1, it can resist external physical damage, thus providing safety protection for the chemical pipeline.

[0032] The first arc-shaped cover 11 in the protective assembly 1 can be placed on one side of the chemical pipeline and also provides an installation base for the second arc-shaped cover 12. Limiting grooves 13 are provided on the upper and lower outer sides of both the first and second arc-shaped covers 11 and 12, and mounting seats 14 are fixedly connected to the upper and lower sides of both the first and second arc-shaped covers 11 and 12. Locking devices 15 are fixedly connected to one side of each mounting seat 14, and two locking bands 16 surround the outer walls of the first and second arc-shaped covers 11 and 12, allowing the two locking bands 16 to be locked at both ends. The device 15 is connected and tensioned, thereby fixing the first arc-shaped cover 11 and the second arc-shaped cover 12 onto the chemical pipeline, so as to provide tight protection for the chemical pipeline and prevent damage to the pipeline from external factors. Since sealing strips 17 are fixedly connected at the joint of the first arc-shaped cover 11 and the second arc-shaped cover 12, and the locking band 16 is a high-strength stainless steel band, and the locking device 15 is a ratchet locking device, and the mating surfaces of the first arc-shaped cover 11 and the second arc-shaped cover 12 are connected by tenons or steps, the first arc-shaped cover 11 and the second arc-shaped cover 12 can be tightly bound to the chemical pipeline. The connection between the two arc-shaped covers 12 is tighter and more secure, which allows the sealing strip 17 to effectively prevent leakage of the medium in the chemical pipeline, thus achieving a good sealing effect. High-strength stainless steel strips provide high strength and corrosion resistance, enabling them to withstand greater tensile forces and ensuring that they will not loosen or break during long-term use. A ratchet lock allows for quick and accurate adjustment of the tension of the locking band 16, further securing the protective component 1 to the chemical pipeline.

Since both the first arc-shaped cover 11 and the second arc-shaped cover 12 are covered with 304 stainless steel, they effectively resist external physical impacts and chemical corrosion, extending the service life of the protective covers. Furthermore, the 304 stainless steel material has excellent high-temperature resistance, allowing the chemical pipeline to maintain structural stability and integrity even in high-temperature environments, preventing deformation or damage due to high temperatures and ensuring the safe operation of the chemical pipeline.

[0033] The first aluminum foil layer 21 in the layered heat insulation buffer assembly 2 can be fixedly connected to the inner cavities of the first arc-shaped cover 11 and the second arc-shaped cover 12, and also provides an installation base for the first sealed silicone mesh layer 22. Since an aerogel felt layer 23 is fixedly connected to the inner side of the first sealed silicone mesh layer 22, and a second sealed silicone mesh layer 24 is fixedly connected to the inner side of the aerogel felt layer 23, and a second aluminum foil layer 25 is fixedly connected to the second sealed silicone mesh layer 24, with the inner side of the second aluminum foil layer 25 connected to the inner lining assembly 3, it can effectively reflect external heat. This reduces heat transfer into the chemical pipeline, thus mitigating the impact of external environmental factors on the pipeline's internal temperature.

The unique mesh structure of the first and second sealed silicone mesh layers 22 and 24 increases the heat conduction path, enhancing insulation. The aerogel felt layer 23 has extremely low thermal conductivity, reducing heat exchange between the inside and outside of the pipeline. This ensures the chemical pipeline maintains a stable temperature under both high and low temperature conditions, preventing damage or performance degradation caused by temperature changes and ensuring its safety. The second sealed silicone mesh layer 24 and the second aluminum foil layer 25 enhance insulation and buffering performance, allowing the second aluminum foil layer 25 to also reflect heat, forming a double insulation barrier in conjunction with the first aluminum foil layer 21 for better protection of the chemical pipeline.

[0034] The expanded graphite felt layer 31 in the inner lining assembly 3 can be fixedly connected to the inner side of the second aluminum foil layer 25, and can also provide an installation base for the flexible ceramic fiber cloth layer 33. Since the expanded graphite felt layer 31 integrates a leak detection sensor 32, and the flexible ceramic fiber cloth layer 33 has good high temperature resistance and corrosion resistance, it can withstand the erosion of high temperature and corrosive media, thereby protecting the expanded graphite felt layer 31 and leak detection sensor 32 from damage, so as to improve the reliability and stability of the safety protection cover for chemical pipelines.
