Description

Technical Field

[0001] The utility model relates to the technical field of flow batteries, in particular to an electrolyte container for a flow battery. Background Art

[0002] As a new type of large-capacity energy storage technology, the energy storage flow battery has become an important part of the power grid peak shaving energy storage device due to its significant advantages such as safe operation, independent design of power and capacity, long service life, and environmental friendliness. The flow battery can effectively improve the acceptance capacity of renewable energy power generation and the energy utilization efficiency, and shows broad application prospects in many fields such as new energy access, smart grid construction, and distributed energy systems. Such batteries transport the electrolyte stored in an external storage tank to the inside of the battery stack through an external circulation pump for chemical reactions, thereby realizing the storage and release of energy.

[0003] During the research and application process of flow batteries, the storage container of the electrolyte has become one of the key factors affecting the battery performance and maintenance convenience. However, there are some obvious deficiencies in the design of existing electrolyte containers:

[0004] Traditional electrolyte containers usually use a threaded connection to fix the bottle cap to the bottle body. When it is necessary to clean or replace the electrolyte, the operator must rotate the bottle cap to remove it from the bottle body. Since the liquid outlet pipe and the liquid return pipe are usually installed on the bottle cap, this increases the complexity of the disassembly process. Especially when the bottle body is made of glass, the surface of the bottle body is smooth, and it is easy to slip during the operation, resulting in damage to the container. This will not only damage the container itself, but may also cause electrolyte leakage, resulting in environmental pollution and even safety hazards. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides an electrolyte container for a flow battery, which solves the problems of inconvenient connection method and safety hazards caused by the breakage of the bottle body.

[0006] The present utility model is realized through the following technical solutions: An electrolyte container for a flow battery, comprising an electrolyte container, a liquid outlet pipe and a liquid return pipe connected to the electrolyte container, characterized in that: the electrolyte container includes a bottle body and a bottle cap; a liquid outlet branch pipe is fixedly arranged at the bottom of the bottle cap; a liquid return branch pipe passing through the bottle cap is fixedly arranged on the bottle cap; a bottle mouth plate is connected to the top of the bottle mouth of the bottle body, and holes for inserting the liquid outlet branch pipe and the liquid return branch pipe are arranged on the bottle mouth plate; magnetic blocks for connecting the bottle body and the bottle cap are symmetrically arranged at the top of the bottle mouth plate and the bottom of the bottle cap; a concave structure is circumferentially arranged in the middle of the bottle body, and a friction sticker for increasing friction is circumferentially arranged on the concave structure; the liquid pipe is inserted into the bottom of the bottle body through the liquid outlet branch pipe; a pipe joint is arranged at the end of the liquid return pipe connected to the bottle cap, and the pipe joint is fixedly connected with the upper part of the liquid return branch pipe by threads.

[0007] Further, grooves for placing a magnetic block and a second magnetic block are arranged at the top of the bottle mouth plate and the bottom of the bottle cap.

[0008] Compared with the prior art, the beneficial effects and characteristics of the present utility model are as follows:

[0009] The present utility model adopts a magnetic connection method, enabling the bottle cap and the bottle body to be separated and closed quickly and easily. Compared with traditional screw connections, this design greatly simplifies the disassembly and assembly process, reduces the operation time and difficulty. Especially in application scenarios where the electrolyte needs to be frequently cleaned or replaced, it can significantly improve work efficiency and reduce the labor intensity of operators.

[0010] The PPSU material with corrosion resistance and impact resistance is selected as the material of the bottle body, effectively avoiding the risk of breakage of traditional glass bottle bodies. Even in the case of accidental dropping or collision, it can maintain the structural integrity and prevent environmental pollution and safety hazards caused by the leakage of electrolyte due to the breakage of the bottle body.

[0011] A concave structure is designed in the middle of the bottle body, and a friction sticker for increasing friction is arranged around the structure. This design not only facilitates the operator to hold, but also effectively prevents slippage during the disassembly and assembly process, further improving the safety and convenience of use.
