Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and specifically to a new type of energy-saving, noise-reducing, integrated and environmentally friendly conveying equipment. Background Art

[0002] Pipeline conveying equipment is an efficient material transmission system widely used in various industries. It mainly consists of pipelines, conveying pumps, valves, pipe fittings, and control systems, etc. The pipeline serves as the main conveying channel, and its material depends on the nature of the conveyed material. For example, metal pipelines are commonly used for conveying oil, natural gas, etc., while plastic pipelines may be used for conveying some liquids or gases with relatively weak corrosiveness. The conveying pump is a key component that provides power and can overcome the pipeline resistance to push the material forward. Different types of pumps are suitable for conveying materials with different viscosities and pressure requirements. For example, centrifugal pumps are commonly used for conveying large-flow and low-viscosity liquids, while plunger pumps perform excellently in high-pressure conveying scenarios. Valves are used to control the flow rate, flow direction, and pressure of the material to ensure precise regulation and safety during the conveying process. In the petrochemical field, pipeline conveying equipment can stably transport crude oil, refined oil, etc. over long distances, reducing transportation losses and risks. In urban gas supply, it can safely and reliably deliver natural gas from the gas source to each household. Its advantages are significant, such as continuous conveying, high efficiency, little influence from the environment, and small floor area, etc. With the development of technology, pipeline conveying equipment is continuously moving towards intelligence, realizing functions such as remote monitoring, automatic adjustment, and fault warning, further improving the operation safety and reliability, and laying a solid foundation for the global transportation of energy and various materials.

The sound-absorbing cotton layer absorbs noise, the air layer can isolate noise, and the butyl rubber layer can isolate vibration. Thus, the noise generated by the friction of the fluid in the second pipeline can be greatly reduced, and at the same time, the secondary noise caused by vibration can be reduced, thereby improving the problem that in the traditional pipeline conveying device, when conveying fluid, noise will be generated due to the friction between the fluid and the pipe wall, which will interfere with the environment.

[0022] 3. In the present invention, the flow resistance bowl provided inside the second pipeline can transfer the flow force of the fluid to the connecting rod, thereby converting it into a rotational force, and then transmitting it to the input end of the generator through the rotating shaft. The electric power can be transmitted to the inside of the acquisition module through the electric wire. Therefore, when driving the acquisition module, it is not necessary to provide additional electric power for the acquisition module, thus achieving an energy-saving effect.

[0023] 4. In the present invention, while transmitting the electric power output by the generator through the electric wire, the rotational speed of the generator can be input into the acquisition module, and then transmitted to the external control system through the remote transmission module.

[0031] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] Please refer to the attached Figure 1 - attached Figure 3 , the embodiment of the present invention provides a new type of energy-saving and noise-reducing integrated environmental protection conveying device, including a first pipe 2 and a second pipe 6. The inner wall of the first pipe 2 is fixedly connected to the outer end of the support bar 7, and the inner end of the support bar 7 is fixedly connected to the outer wall of the second pipe 6. A butyl rubber layer 3 is arranged inside the first pipe 2, an air layer 4 is arranged inside the butyl rubber layer 3, and a sound-absorbing cotton layer 5 is arranged inside the air layer 4. There are five support bars 7 arranged in a circular array with the center of the second pipe 6 as the axis. The support bars 7 divide the butyl rubber layer 3, the air layer 4, and the sound-absorbing cotton layer 5 into ten groups. Polyethylene terephthalate films are arranged on the outer walls of the butyl rubber layer 3 and the air layer 4, and an isolation structure is arranged on the outer wall of the sound-absorbing cotton layer 5.

[0034] Specifically, the first pipe 2 can play a role in installing and protecting the internal structure. The second pipe 6 can play a role in conveying fluids. The support bar 7 can play a role in fixing and supporting the first pipe 2 and the second pipe 6, and at the same time can play a role in dividing the butyl rubber layer 3, the air layer 4, and the sound-absorbing cotton layer 5, so that flexible adjustment can be made for the butyl rubber layer 3, the air layer 4, and the sound-absorbing cotton layer 5 at different positions. The butyl rubber layer 3 can play a role in suppressing the vibration of the pipe wall, converting the vibration energy into heat energy, thereby reducing the noise radiated outward by the vibration of the pipe wall, and can also serve as a protective layer to protect the internal structure. The air layer 4 can utilize the principle of reflection and refraction of sound waves at the interfaces of different media to weaken the remaining sound wave energy after passing through the sound-absorbing cotton, and at the same time play a buffering role, reducing the vibration transmission of the inner sound-absorbing cotton and stabilizing the acoustic performance. The sound-absorbing cotton layer 5 can utilize the internal porous structure to convert the noise sound energy generated by the fluid in the second pipe 6 into heat energy, thereby absorbing sound and reducing the energy of the initial noise. The polyethylene terephthalate film can prevent the air in the air layer 4 from leaking, maintain the air pressure stability of the air layer 4, ensure the acoustic performance of the air layer 4, and serve as a physical barrier to protect the air layer 4.

[0035] Please refer to the attached Figure 3 , the isolation structure includes a plastic net, and the plastic net wraps the outer wall of the sound-absorbing cotton layer 5.

[0036] Specifically, the plastic net can prevent the fibers of the sound-absorbing cotton from falling off and entering the air layer 4, and play a role in supporting the sound-absorbing cotton, so that the sound-absorbing cotton maintains its structural shape during long-term use and maintains a good sound-absorbing effect.

[0037] Please refer to the attached Figure 1 - attached Figure 5 As shown in the figure, a protective shell 1 is provided on the outer wall of the first pipe 2. A collection module 11 is provided inside the protective shell 1. A remote transmission module is provided inside the collection module 11. The collection module 11 is electrically connected to the output end of the generator 13 through an electric wire 12. The outer wall of the generator 13 is fixedly arranged inside the protective shell 1. The input end of the generator 13 is fixedly arranged at one end of the rotating shaft 9. A bearing 14 is arranged on the outer wall of the rotating shaft 9 near the generator 13. The outer wall of the bearing 14 is fixedly arranged inside the protective shell 1. The other end of the rotating shaft 9 is fixedly connected to one end of the connecting rod 10. The other end of the connecting rod 10 is fixedly arranged on the outer wall of the flow blocking bowl 8. The rotating shaft 9 penetrates through the first pipe 2 and the second pipe 6. The flow blocking bowl 8 and the connecting rod 10 protrude from the inner wall of the second pipe 6. The collection module 11 is used to collect the rotation speed of the generator 13, and the remote transmission module is used to transmit the information collected by the collection module 11.

[0038] Specifically, the protective shell 1 can play a role in protecting the internal structure and can be placed at any part of the first pipe 2. Through the collection module 11, the rotation speed information of the generator 13 can be collected in real time, and then converted into the flow velocity information of the fluid inside the second pipe 6. Through the remote transmission module, the flow velocity information of the fluid can be transmitted to the external control system in real time. Thus, the flow velocity information of the fluid at each part can be observed in real time, and the fault can be quickly checked. Through the electric wire 12, the electric power and the rotation speed information of the generator 13 can be transmitted. Through the generator 13, the rotational force can be converted into electric power to supply power to the collection module 11 and the remote transmission module. Thus, an external power supply is not required. Through the rotating shaft 9, the rotational force transmitted by the connecting rod 10 can be transmitted to the input end of the generator 13. Through the bearing 14, the rotating shaft 9 can be supported. Thus, the rotating shaft 9 can rotate more stably and smoothly, thereby improving the power generation efficiency. Through the connecting rod 10, the thrust transmitted by the flow blocking bowl 8 can be converted into rotational force.

[0039] Please refer to the attached Figure 1 - attached Figure 2 As shown in the figure, a delivery pump 16 is provided at the end of the first pipe 2. The delivery pump 16 is fixedly arranged with the first pipe 2 through a flange 15.

[0040] Specifically, the delivery pump 16 can play a role in pushing the fluid and provide power for the delivery of the fluid. The flange 15 can play a role in fixing the delivery pump 16.

[0041] Please refer to the appendix Figure 6 The first pipe 2 and the second pipe 6 comprise raw materials in the following parts by weight: recycled high-density polyethylene particles: 70 - 80 parts, recycled polypropylene particles: 10 - 20 parts, filler: 5 - 10 parts, compatibilizer: 1 - 3 parts, antioxidant: 0.1 - 0.5 parts.

[0042] Specifically, the main body of the first pipe 2 and the second pipe 6 can be composed of recycled high-density polyethylene particles and recycled polypropylene particles. The use of recycled materials can achieve environmental protection purposes through recycling. The filler can improve many properties of the pipe, such as hardness, dimensional stability, lubricity, antistatic property, ultraviolet resistance, heat resistance, and flame retardancy, and can also reduce costs. The compatibilizer can enhance the compatibility between recycled high-density polyethylene and recycled polypropylene, reduce phase separation, and make them mix more evenly, thereby improving the overall performance of the pipe material. The antioxidant can prevent the recycled plastic from degrading due to oxidation during processing and use, extend the service life of the pipe, and maintain the stability of the pipe material performance.

[0043] Please refer to the appendix Figure 6 The filler comprises raw materials in the following percentages: calcium carbonate 40 - 60%, glass fiber 20 - 30%, talcum powder 10 - 20%, mica powder 5 - 15%, and carbon black 1 - 5%.

[0044] Specifically, calcium carbonate can improve the hardness and dimensional stability of the pipe, reduce costs, and to a certain extent, can also improve the flame retardancy of the pipe. Glass fiber can significantly enhance the strength and heat resistance of the pipe, provide support when the pipe withstands internal pressure or external impact, and prevent the pipe from bursting. Talcum powder can improve the hardness, dimensional stability, and lubricity of the pipe, make the pipe surface smoother, reduce fluid resistance, and at the same time has certain electrical insulation properties. Mica powder can improve the ultraviolet resistance and weather resistance of the pipe, and can also form a heat insulation barrier to reduce heat transfer inside and outside the pipe. Carbon black can improve the antistatic property and ultraviolet absorption ability of the pipe, and can change the color of the pipe for distinguishing uses, and can also reduce the risk of accidents caused by static electricity in the pipe.

[0045] Please refer to the appendix Figure 6 The compatibilizer comprises raw materials in the following percentages: maleic anhydride grafted polymer 50 - 70%, acrylate copolymer 20 - 30%, and ethylene-vinyl acetate copolymer 10 - 20%.

[0046] Specifically, the maleic anhydride grafted polymer can form chemical bonds between different plastic phases, improve the compatibility between recycled high density polyethylene and recycled polypropylene, reduce the phase separation phenomenon. The acrylate copolymer can interact with the polar groups on the surface of recycled plastics through its own functional groups, promote the dispersion and compatibility of recycled high density polyethylene and recycled polypropylene, and enhance the material stability. The ethylene-vinyl acetate copolymer can enhance the compatibility between recycled high density polyethylene and recycled polypropylene, and at the same time endow the pipeline material with certain flexibility, improving the comprehensive performance of the pipeline.

[0047] Please refer to the appendix Figure 6 , the antioxidant includes raw materials in the following percentages: 40-60% of hindered phenol antioxidants, 30-40% of phosphite antioxidants, and 10-20% of thioester antioxidants.

[0048] Specifically, the hindered phenol antioxidant can capture the free radicals generated during the processing and use of plastics, inhibit the oxidation chain reaction, thus effectively delaying the aging of recycled plastics and extending the service life of the pipeline. The phosphite antioxidant can decompose the hydroperoxides generated during the processing and use of plastics, prevent them from decomposing to generate free radicals, thereby preventing the plastic material from degrading due to oxidation and maintaining the stable performance of the pipeline material. The thioester antioxidant can decompose hydroperoxides, terminate the oxidation chain reaction, and can produce a synergistic effect with the hindered phenol antioxidant, better inhibiting the oxidative degradation of recycled plastics during processing and use, and extending the service life of the first pipeline 2 and the second pipeline 6.
