Description

Technical Field

[0001] This utility model relates to the technical field of electrolyte production equipment, and more specifically, to an electrolyte preparation tank with a spiral stirring mechanism. Background Technology

[0002] Electrolytes have a wide range of applications in many fields, such as the battery industry, electrolytic capacitors, and supercapacitors. In the battery field, electrolytes, as carriers of ion transport, play a key role in battery performance. They are usually prepared in a closed environment by special sulfuric acid, distilled water, lithium salts, organic solvents, and additives in a specific ratio. When making lead-acid batteries, corresponding electrolyte preparation tanks are usually required to prepare the electrolyte.

[0003] Utility model patent CN215611224U discloses an aluminum-air battery electrolyte preparation device, including a support platform, a preparation tank, and a sealed cover. The preparation tank is fixedly connected to the upper part of the support platform. A sealed cover is detachably connected to the preparation tank. Handle loops are provided on both sides of the preparation tank, and the preparation tank is fixedly connected to the handle loops. This utility model utilizes multiple feed pipes of different specifications to simultaneously place various electrolyte materials, and allows for observation of the preparation process and monitoring of the gas pressure, enabling rapid and safe preparation of aluminum-air battery electrolyte.

[0004] While the above-mentioned technical solutions have their advantages, there are still some shortcomings in the mixing tanks used in the electrolyte preparation process. For example, traditional mixing tanks mostly use conventional stirring blades for stirring, which is a relatively simple stirring method. This results in uneven mixing of the electrolyte components. For instance, in some large-capacity mixing tanks, there is a significant difference in electrolyte component concentration between the edge area and the center area of ​​the tank, which seriously affects the uniformity of electrolyte quality and thus affects the performance of related products.

[0005] While some preparation tanks are equipped with multiple stirring devices to improve mixing, this not only significantly increases equipment costs and energy consumption but also complicates the equipment structure and increases maintenance difficulty. Therefore, we propose an electrolyte preparation tank with a spiral stirring mechanism. Utility Model Content

The first spiral blade 27 and the second spiral blade 281 are both spiral in shape. The secondary shaft 28 is set to tilt downward at 30 degrees to 60 degrees. When the drive motor 22 drives the stirring shaft 26 to rotate, the first spiral blade 27 can generate axial and radial liquid flow. The secondary shaft 28 and its second spiral blade 281 strengthen the stirring range and force with a specific tilt angle. The bottom stirring plate 271 is attached to the bottom wall of the tank 1 to stir the deposited material, realize multi-dimensional stirring, and make the electrolyte mix more fully and evenly.

[0035] like Figure 1 and Figure 2 As shown, multiple support legs 10 are fixedly installed at the bottom of the tank body 1, and a support base 11 is fixedly installed at the bottom end of the support legs 10. Multiple bolt holes 111 are provided in the support base 11 so that the tank body 1 can be placed stably and fixed to the ground or installation platform by bolts, thereby enhancing the stability of the equipment during operation and preventing the tank body 1 from shifting or tilting due to stirring vibration.

[0036] like Figure 1As shown, a drain pipe 12 is fixedly installed on one side of the bottom of tank 1, and a discharge pipe 13 is fixedly installed on the other side of the bottom of tank 1. Valves 14 are fixedly installed on both the drain pipe 12 and the discharge pipe 13, so that the prepared electrolyte can be smoothly discharged through the discharge pipe 13. After cleaning tank 1, the wastewater can be discharged through the drain pipe 12, which facilitates unloading and sewage discharge operations, effectively controls the liquid flow direction, and improves the convenience and efficiency of operation.

[0037] like Figure 1 and Figure 3 As shown, the tank 1 consists of an outer tank 16 and an inner tank 18 disposed inside the outer tank 16.

[0038] like Figure 1 and Figure 3 As shown, a temperature-controlled electric heater 15 is fixedly installed on the outside of the tank body 1. The part of the tank body 1 located at the temperature-controlled electric heater 15 has a single-layer structure. The temperature-controlled electric heater 15 is directly sleeved on the inner tank 18, so that the temperature-controlled electric heater 15 can directly heat the inner tank 18, reduce heat transfer loss, improve heating efficiency, accurately control the temperature of the electrolyte in the tank, and ensure the smooth progress of the preparation process.

The output shaft of the drive motor 22 is connected to the input shaft of the reducer 21, and the output shaft of the reducer 21 is connected to the coupling 20. The stirring shaft 26 is connected to the output end of the coupling 20, so that the power generated by the drive motor 22 is reduced and increased in torque by the reducer 21, and then stably transmitted to the stirring shaft 26 through the coupling 20, ensuring that the stirring shaft 26 drives the stirring components to rotate at a suitable speed and torque, thereby achieving efficient and stable stirring.

[0040] like Figure 1 As shown, multiple feed pipes 23 are fixedly installed on the top of the sealed top cover 2, allowing materials of different compositions to be accurately added to the tank 1 through the feed pipes 23; a water inlet flushing pipe 24 is also fixedly installed on the top of the sealed top cover 2, allowing the inside of the tank 1 to be flushed through the water inlet flushing pipe 24 after preparation; a pressure relief pipe 25 is fixedly installed on the sealed top cover 2, and a pressure relief valve 251 is fixedly installed on the pressure relief pipe 25.

[0041] like Figure 1As shown, a vacuum pump 3 is installed on one side of the tank 1. The suction end of the vacuum pump 3 is connected to the inside of the tank 1 through a suction pipe 30. This allows the air inside the tank 1 to be extracted during electrolyte preparation, creating a vacuum environment to prevent air and moisture from affecting the electrolyte composition and ensuring the purity and preparation quality of the electrolyte.

[0042] It is worth noting that both the feed pipe 23 and the water flushing pipe 24 are fixedly installed on external pipes with valves, so that the opening and closing of the pipes can be controlled by the valves.

[0043] Finally, it should be noted that the drive motor 22, temperature-controlled electric heater 15, vacuum pump 3, corresponding control system, and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0044] In use, the electrolyte preparation tank with a spiral stirring mechanism of this utility model is used to add the material to be prepared into the tank 1 through different feed pipes 23. The vacuum pump 3 is turned on, and the air in the tank 1 is extracted through the suction pipe 30 to create a vacuum environment and prevent air from affecting the electrolyte composition. The drive motor 22 is started, and the power is reduced and increased in torque by the reducer 21, and then transmitted to the stirring shaft 26 through the coupling 20. This drives the first spiral blade 27, the secondary shaft 28 and the second spiral blade 281 on it and the bottom stirring plate 271 to rotate, so as to carry out multi-dimensional stirring and mixing of the electrolyte.

[0045] During the stirring process, if necessary, the electrolyte in the tank 1 is heated by the temperature-controlled electric heater 15. After the preparation is completed, the drive motor 22 is turned off and the valve 14 on the discharge pipe 13 is opened to discharge the prepared electrolyte.

[0046] After unloading is completed, clean water is injected into the tank 1 through the water inlet flushing pipe 24. At the same time, the drive motor 22 is started to drive the stirring component to rotate and clean the inside of the tank 1. The wastewater after cleaning is discharged through the valve 14 on the drain pipe 12.
