Description

Technical Field

[0001] The utility model relates to the field of electrolyte mixing devices, in particular to an electrolyte mixing device for a flow battery. Background Art

[0002] An electrolyte mixing device for a flow battery is a device used to mix the electrolyte in the battery, aiming to ensure that the electrolyte maintains a uniform composition and temperature distribution during the battery cycle. This device usually consists of a rotating stirrer, a stirring rod or other mixing elements, which mix various components in the electrolyte evenly by stirring or agitating to improve the battery performance and cycle life.

[0003] After retrieval, the existing Chinese patent publication number is: CN216654190U, an electrolyte mixing device for a vanadium redox flow battery with a cooling mechanism, including a box body. A plurality of supporting feet are fixedly connected to the bottom end of the box body. A fixed funnel is fixedly connected inside the box body. A fixed cylinder is fixedly connected to the bottom end of the fixed funnel. The utility model relates to the technical field of electrolyte mixing devices; for the electrolyte mixing device for a vanadium redox flow battery with a cooling mechanism, by providing a fixed plate, a sliding plate and a spring to separate the space inside the fixed cylinder, the electrolyte raw materials are first mixed above the fixed plate, and then the raw materials are gradually added. As the raw materials above the sliding plate increase, the spring is compressed and contracted to drive the sliding plate to move downward, so that the raw materials flow downward. The lower-layer spiral blade rod and the stirring blade are used to stir and cool the electrolyte, dividing the stirring and mixing of the device into two parts, enabling the raw materials in the upper layer to be quickly mixed at a higher temperature and then cooled by the lower layer, enhancing the practicability of the device.

[0004] In the specific implementation of the above patent, first, electrolyte raw materials are added into the device through the feeding port. The raw materials are guided to the inside of the fixed cylinder through the fixed funnel. The motor drives the stirring rod and the stirring blade to rotate to stir and mix the raw materials above the fixed plate. Then, more raw materials are added into the device. The raw materials squeeze the sliding plate to move downward and gradually add raw materials below the fixed plate. While being stirred by the stirring blade, the bottom end of the stirring rod drives the spiral blade rod to rotate through the first gear and the second gear, driving the electrolyte raw materials below to rise. The cooling plates at both ends of the fixed block cool the electrolyte inside the fixed block, enabling the raw materials below the fixed plate to be stirred and cooled simultaneously. After cooling, the electrolyte raw materials leave the device through the discharge pipe. In this patent, the motor drives the stirring rod to rotate, and then the stirring rod drives the first gear, the second gear and the spiral blade rod to rotate, improving the simplicity of the device operation. However, in this patent, the main body box only has small openings for feeding and discharging. When it is necessary to maintain the stirring device inside the box body, the box body cannot be quickly disassembled, which makes the maintenance work more troublesome, increasing the complexity and cost of maintenance. Therefore, an electrolyte mixing device for a flow battery is proposed to solve the above problems. Summary of the Invention

[0038] Working principle: Pour the electrolyte to be mixed into the mixing barrel 1 through the feed port 5, and then start the motor 3. The motor 3 will drive the rotating rod 4 to rotate, and the rotating rod 4 will also drive the connecting rod 17 and the stirring and cleaning piece 18 to rotate to mix and stir the electrolyte inside the mixing barrel 1. The connection between the stirring and cleaning piece 18 and the connecting rod 17 is square to prevent the stirring and cleaning piece 18 from shaking when being driven. After the mixing and stirring are completed, it is necessary to clean the remaining electrolyte in the mixing barrel 1. The second pushing spring 20 will push the pushing seat 21, and then push the two pushing rods 22, so that the pushing rods 22 push the stirring and cleaning piece 18 to tightly fit against the inner wall of the mixing barrel 1. This enables less dead corners and hidden areas when cleaning the inside of the mixing barrel 1, making the cleaning more thorough. In this way, dirt and residues can be effectively removed, and the inside of the stirring barrel can be kept clean and hygienic. When it is necessary to maintain the stirring device inside the mixing barrel 1, by pressing the button 16, the button 16 will press down the pressing groove 14 and the sliding block 13 through the pressing post 15, thereby driving the sliding block 13 to move forward. The sliding block 13 will drive the clamping post 10 to leave the inside of the clamping groove 8, so that the clamping post 10 is no longer clamped with the clamping groove 8. At this time, the barrel cover 2 can be removed from the top of the mixing barrel 1 to maintain the stirring device. After the maintenance is completed, when the barrel cover 2 is repositioned and placed on the top of the mixing barrel 1, press the button 16 again with your hand, so that the button 16 presses down the pressing groove 14 and the sliding block 13 through the pressing post 15 again, thereby driving the sliding block 13 to move forward. The sliding block 13 will drive the clamping post 10 so that the clamping post 10 does not block the barrel cover 2. After the barrel cover 2 is placed through the limit rod 24, release your hand, and the clamping post 10 will be pushed by the placement groove 9 and the clamping post 10 to re-clamp with the clamping groove 8, and then fix the barrel cover 2. By quickly disassembling the barrel cover 2, maintenance personnel can quickly maintain the stirring device, quickly carry out repairs, cleaning or component replacement, thereby saving maintenance time and reducing maintenance costs.
