Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electrolyte tank, specifically to a high -efficient energy -conserving heat preservation electrolyte storage and transportation container. BACKGROUND

[0002] As an important chemical material, electrolyte is widely used in battery, electronic device and chemical reaction fields. Due to its chemical properties, electrolyte is sensitive to temperature and environmental changes. During storage and transportation, electrolyte needs strict temperature control and leakage protection, otherwise its chemical properties will change, affecting application performance and causing safety problems. The existing full vanadium flow battery negative electrolyte tank with hydrogen recovery device (publication number: CN220753494U) has the following disadvantages and needs further improvement.

[0003] 1. The traditional equipment relies on simple external heating equipment or no heating measures. This design cannot accurately control the temperature change of different environments, which easily leads to electrolyte temperature being too high or too low, affecting its performance stability. Moreover, the traditional heating method consumes a lot of energy, and the heat is easily lost, which is difficult to distribute evenly in the inner wall of the container, causing resource waste. Therefore, there is an urgent need for an electrolyte container with energy-saving function.

[0004] 2. The traditional equipment only relies on the thickness of the container wall to slow down the temperature change. The heat insulation effect is limited, and the temperature fluctuation of electrolyte is large in long-distance transportation or in cold and high-temperature environments, which is difficult to maintain its stability. The sharp change of temperature not only affects the chemical properties of electrolyte, but also causes pressure change in the container, increasing the safety hidden trouble in the storage and transportation process. Therefore, there is an urgent need for an electrolyte container with heat preservation function.

[0005] 3. The sealing element of the traditional equipment often uses ordinary rubber or simple sealing design, which lacks corrosion resistance and is easily corroded by electrolyte, leading to sealing failure. In the transportation and handling process, poor sealing will cause electrolyte leakage, which not only pollutes the environment, but also brings safety hazards. Therefore, there is an urgent need for an electrolyte container with leakage prevention function. INVENTION CONTENTS

[0015] 2. The utility model can ensure that the temperature of the electrolyte remains stable under different temperature environments by adding the polyurethane heat preservation layer.

[0024] EMBODIMENT

[0025] Please refer to Figures 1-3 The utility model provides a technical scheme:

[0026] The application discloses a high-efficiency and energy-saving heat preservation electrolyte storage and transportation container, which is characterized in that a discharge port 2 is arranged below a main body 1, a feeding port 3 is arranged above the main body 1, a temperature control switch 4 is arranged on one side of the main body 1, a one-way valve 5 is arranged above the main body 1, a corrosion-resistant sealing ring 6 is arranged in the main body 1, a polyurethane heat preservation layer 7 is arranged in the main body 1, a flexible heating film 8 is arranged in the main body 1, and a temperature control drive 9 is arranged in the main body 1.

[0027] The flexible heating film is closely attached to the inner wall of the container and covers the outer side of the heat preservation layer and is connected to the temperature control switch through a wire. The temperature control switch is arranged on the outer wall of the container and is connected with a power supply through a power supply interface to control the start and stop of the heating film.

[0028] The polyurethane heat preservation layer is arranged on the outer layer of the inner wall of the container and closely attached to the main body to provide high-efficiency heat insulation effect. The heat preservation layer and the container wall are closely adhered through an adhesive to ensure the heat insulation performance.

[0029] The corrosion-resistant sealing ring is arranged at the connection of the discharge port, the feeding port and the container cover and is fixed through a clamping groove or a thread connection to form a sealing protection.

[0030] The one-way valve is arranged at the liquid discharge port and is used for controlling the flow direction of the liquid to prevent backflow or leakage of the liquid.

[0031] The flexible heating film is a thin heating element which can closely attach to the inner wall or the outer wall of the container to provide uniform heating effect for the electrolyte. The temperature control switch is used for monitoring the internal temperature of the container in real time and adjusting the working state of the heating film. When the internal temperature is lower than the set value, the temperature control switch is turned on to activate the flexible heating film to heat the container. When the temperature reaches the set value, the temperature control switch is turned off to stop heating. The design reduces unnecessary energy consumption, ensures that the electrolyte is maintained in an optimal temperature range and avoids performance loss.

[0032] The polyurethane is a low-thermal-conductivity material. By arranging the polyurethane heat preservation layer on the inner wall of the container, heat exchange between the container and the outside can be significantly reduced, and the temperature of the electrolyte can be maintained stable during long-time storage and transportation. The polyurethane layer not only has excellent heat insulation performance but also is durable and not easy to age, and can maintain the heat insulation effect for a long time in different environments and reduce energy loss.

[0033] The corrosion-resistant sealing ring is made of polytetrafluoroethylene and can withstand the corrosion of the electrolyte to ensure long-time sealing performance. The one-way valve ensures that the liquid only flows in one direction to prevent backflow or leakage, further improving the safety during the storage and transportation process. The combination of these components can prevent the leakage of the electrolyte, protect the environment and prolong the service life of the equipment.

[0034] To verify the temperature control effect of the flexible heating film and the temperature control switch, multiple temperature maintenance experiments were conducted. The experiments were conducted at different ambient temperatures by recording the internal temperature changes and the number of heating film start-stop times, and the energy consumption and temperature control effect were analyzed.

[0035]

[0036] The experimental data showed that in a low temperature environment, the flexible heating film could quickly heat up to the target temperature, and the temperature control switch effectively reduced the phenomenon of excessive heating.

[0037] To test the insulation effect of the polyurethane insulation layer, the container was placed in an extremely low temperature and high temperature environment, and the internal temperature change was recorded.

[0038]

[0039] The experimental results showed that the polyurethane insulation layer could effectively insulate the external temperature in extreme environments, maintain the stability of the electrolyte temperature, and ensure the stability of the electrolyte performance.

[0040] To verify the corrosion and leakage prevention performance of the sealing ring and the one-way valve, we conducted long-term immersion and pressure resistance tests. The sealing ring and the one-way valve were immersed in the electrolyte for 100 hours, and their pressure resistance performance was tested to ensure that they would not leak due to corrosion or pressure in actual use.

[0041] Soaking time (hours) Pressure resistance test pressure (MPa) Sealing performance retention 100 0.8 Good 200 1 Good Good Good Good Good Good Good Good Good Good Good Good Good Good Good Good Good Good Good Good Good Good

[0042] After long-term immersion and high-pressure testing, the sealing ring and the one-way valve both maintained good sealing performance and did not exhibit any leakage or corrosion, proving that the design has good durability in corrosive environments.

[0043] To ensure that the electrolyte only flows in one direction, the design of the one-way valve needs to consider the flow rate of the liquid through the valve. The liquid flow through the one-way valve can be analyzed using Bernoulli's equation:

[0044]

[0045] where,

[0046] P1 and P2 are the pressures of the fluid at the inlet and outlet (Pa);

[0047] v1 and v2 are the velocities of the fluid at the inlet and outlet (m / s);

[0048] ρ is the density of the fluid (kg / m 3 );

[0049] g is the acceleration due to gravity (m / s 2 );

[0050] h1 and h2 are the heights (m) of the fluid at the inlet and outlet.

[0051] By controlling the valve opening pressure P1 and the outlet pressure P2 of the one-way valve, the fluid is ensured to flow in one direction at a set pressure. When the inlet pressure is lower than the valve setting, the valve is closed, preventing the electrolyte from flowing backward or leaking.

Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application.
