[0025] The electrolyte delivery pipeline provided in this application includes an outer pipe and an inner pipe installed inside the outer pipe. The outer pipe comprises several rigid inlet pipe sections laid according to a predetermined route, while the inner pipe is a single, corrosion-resistant, flexible pipe. This application uses the outer and inner pipes to form an electrolyte delivery pipeline. The outer pipe ensures the pipeline's strength, while the inner pipe ensures its corrosion resistance, resulting in lower costs compared to using 316 stainless steel pipes for the entire pipeline. Furthermore, the inner pipe is a single, corrosion-resistant, flexible pipe, with no joints allowed in the middle, significantly reducing the risk of leakage and making the pipeline more stable and reliable, thus reducing maintenance costs. In addition, the flexible pipe possesses excellent flexibility and plasticity, enabling it to adapt to various complex delivery environments.
[0026] like Figs. 1-2 As shown, one embodiment of this application provides an electrolyte delivery pipeline, including an outer pipe 100 and an inner pipe 200 disposed within the outer pipe 100. The outer pipe 100 includes several rigid inlet pipes laid according to a preset route, and the inner pipe 200 is a single corrosion-resistant flexible pipe.
[0027] In implementation, the outer tube 100 consists of several inlet tubes, such as 1, 2, 4, 5, 8, 10, or any number of inlet tubes that meet the usage requirements. The inlet tubes are hollow rigid tubes; for example, the inlet tubes can be made of iron, stainless steel, or other rigid tubes, without limitation.
[0028] In some embodiments, the inlet pipe, i.e. the outer pipe 100, can be made of stainless steel. Stainless steel pipe can effectively ensure the strength and corrosion resistance of the pipeline, while improving the overall safety.
[0029] As one possible implementation, the outer tube 100 can be made of 304 stainless steel. Compared with the traditional use of 316 stainless steel pipe, the use of 304 stainless steel pipe in this application is less costly, while maintaining good corrosion resistance.
[0030] Optionally, since the outer pipe 100 is composed of several inlet pipes, adjacent inlet pipes are sealed and connected by a customized sealing external clamp (not shown in the figure). The customized external sealing external clamp can ensure that there is no leakage at the stainless steel pipe joint.
[0031] The inner tube 200 uses a corrosion-resistant flexible tube to ensure the safety of the electrolyte delivery pipeline. Furthermore, the inner tube 200 is a single, continuous flexible tube, meaning there are no joints allowed in the middle, greatly reducing the risk of leakage, making the pipeline more stable and reliable, and reducing maintenance costs.
[0032] Flexible pipes have excellent flexibility and plasticity, and can adapt to various complex transportation environments.
[0033] In some embodiments, the flexible pipe can adopt a flexible material with chemical corrosion resistance, such as PFA (perfluoroalkoxy polymer), PEEK (polyether ether ketone), PPS (polyphenylene sulfide), FEP (fluorinated ethylene propylene), and PTFE (polytetrafluoroethylene), and preferably adopts a PFA pipe.
[0034] For example, taking the PFA pipe as an example, PFA is a high-performance plastic, and the chemical composition of PFA mainly includes a copolymer of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene, with a melting point of about 580℉ (about 300℃) and a density of 2.13-2.16 g / cm3. PFA performs well in the temperature range of -80℃ to 260℃, has excellent chemical corrosion resistance, can resist the corrosion of all chemicals, has the lowest friction coefficient among plastics, has temperature-independent electrical insulation, and has excellent chemical stability and high-temperature resistance.
[0035] Alternatively, several sections of the liquid inlet pipe are laid according to the preset route, and the outer pipe 100 of the electrolyte conveying pipeline is laid while the inner pipe 200 is laid. When laying the inner pipe 200, careful pipe threading is required, for example, careful pipe threading is required at the joints, tees, and elbows of the outer pipe 100 to avoid scratching the inner pipe 200.
[0036] As a possible implementation, the inner surface of the outer pipe 100 is smooth. That is, the inner wall of the outer pipe 100 can be polished, for example, the places with burrs in the inner wall of the outer pipe 100 are polished first to ensure the smoothness of the inner wall of the outer pipe 100, avoid scratching the inner pipe 200, and ensure the safety of the pipeline.
[0037] The electrolyte conveying pipeline provided by the present application includes an outer pipe 100 and an inner pipe 200 arranged in the outer pipe 100. The outer pipe 100 includes several sections of rigid liquid inlet pipes laid according to a preset route, and the inner pipe 200 adopts a whole corrosion-resistant flexible pipe. The present application forms an electrolyte conveying pipeline by the outer pipe 100 and the inner pipe 200. The outer pipe 100 ensures the strength of the pipeline, and the inner pipe 200 ensures the corrosion resistance of the pipeline, which is lower in cost than using a whole 316 stainless steel pipeline. Moreover, the inner pipe 200 adopts a whole corrosion-resistant flexible pipe, and the whole flexible pipe is not allowed to have joints in the middle, which greatly reduces the risk of leakage, makes the pipeline more stable and reliable, and reduces the maintenance cost. In addition, the flexible pipe has excellent flexibility and plasticity, and can adapt to various complex conveying environments.
[0038] In some embodiments, the electrolyte conveying pipeline provided by the present application further includes a leakage detection device 300 arranged on the pipeline of the outer pipe 100 and communicating with the inner pipe 200, for detecting whether the electrolyte leaks.
[0039] In implementation, the leakage detection device 300 can be a common leakage detection device 300 on the market, which will not be described in detail. The leakage detection device 300 can be a U-shaped leakage detection device 300, as shown in Fig. 2 The leakage detection device 300 can detect the leakage of the electrolyte in the first time, and ensure the safety of production.
[0040] In some possible embodiments, a leakage detection device 300 is arranged at each interval of a preset distance (for example, 20 meters, 25 meters, 30 meters, or 35 meters, etc.) along the pipeline, to ensure safety.
[0041] In some embodiments, the leakage detection device 300 further comprises an emergency discharge port 400, which is used to discharge the electrolyte when the leakage detection device 300 detects a failure of the electrolyte conveying pipeline.
[0042] In some embodiments, the electrolyte conveying pipeline provided by the present application further comprises a thermal insulation layer 500, which is wrapped around the outer periphery of the outer pipe 100. By sleeving the thermal insulation layer 500 around the outer periphery of the outer pipe 100, heat loss can be reduced, and the efficiency of electrolyte conveying can be improved. At the same time, the thermal insulation layer 500 can also protect the pipeline to some extent and prolong the service life.
[0043] In some embodiments, the electrolyte conveying pipeline provided by the present application further comprises a mounting bracket (not shown in the figure), which is laid according to a preset route to support the electrolyte conveying pipeline.
[0044] The pipeline needs to be fixed by the mounting bracket to prevent excessive shaking of the pipeline. At the same time, the installation of the bracket requires a certain slope (for example, 0.2%, 0.3%, 0.4%, or 0.5%) at each preset distance (for example, 20 meters, 25 meters, 30 meters, or 35 meters, etc.), to ensure the stability of the pipeline.
[0045] In a second aspect, the present application provides a battery production system, which comprises the electrolyte conveying pipeline as described above.
[0046] Those skilled in the art can clearly understand that, for the convenience and brevity of description, the structure and implementation principle of the battery production system described above can refer to the corresponding structure and implementation principle in the foregoing embodiments, which will not be described in detail here.
[0047] The electrolyte conveying pipeline provided by the application comprises an outer pipe 100 and an inner pipe 200 arranged in the outer pipe 100, the outer pipe 100 comprises a plurality of rigid liquid inlet pipes arranged according to a preset route, and the inner pipe 200 adopts a whole corrosion-resistant flexible pipe. The application forms the electrolyte conveying pipeline through the outer pipe 100 and the inner pipe 200, the outer pipe 100 guarantees the strength of the pipeline, and the inner pipe 200 guarantees the corrosion resistance of the pipeline, and the cost is lower than that of a whole pipeline adopting a 316 stainless steel pipeline. Moreover, the inner pipe 200 adopts a whole corrosion-resistant flexible pipe, and the whole flexible pipe is not allowed to have a joint in the middle, so that the risk of leakage is greatly reduced, the pipeline is more stable and reliable, and the maintenance cost is reduced. In addition, the flexible pipeline has excellent flexibility and plasticity, and can adapt to various complex conveying environments.
[0048] The above is only a preferred embodiment of the application, and is not used to limit the application, and any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the application.
