[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] In one embodiment, see Figures 1-11 An acid preparation device for battery production includes a base 1, a support mechanism 2 and a mixing mechanism 3;

[0035] Support mechanism 2 includes a guide post 6 located at the end of base 1. A guide block 8 is slidably connected to the middle of the guide post 6. The guide block 8 is rotatably connected to a suspension rod 9. A mixing tank 10 is fixedly connected to one end of the suspension rod 9 near the center of base 1. A water bath 11 that mates with the mixing tank 10 is provided on base 1. Base 1 is placed horizontally on the ground, and the mixing tank 10 is positioned laterally above base 1. The mixing tank 10 is a hollow cylindrical structure. Further details are provided in the appendix. Figure 2 The direction is described as follows: feed inlets 23 are set on the upper left and right sides of the mixing tank 10. A throttle valve is set in the middle of the feed inlet 23 and the feed inlet 23 is connected to the inside of the mixing tank 10. The left and right suspension rods 9 are set above the left and right ends of the mixing tank 10. Therefore, under the action of gravity, the mixing tank 10 will keep the feed inlet 23 facing upward. Guide columns 6 are vertically set on the left and right ends of the base 1. Guide blocks 8 are slidably connected above the guide columns 6. The guide blocks 8 are rotatably connected to the end of the suspension rods 9. Through the cooperation of the guide columns 6 and the guide blocks 8, the mixing tank 10 can only move vertically up and down.

[0036] The mixing mechanism 3 is rotatably connected to a left-right oriented main shaft 24 at the center of the mixing tank 10. The axis of the main shaft 24 is collinear with the axis of the mixing tank 10. Parallel rotating beams 29 are fixedly connected to the center of both sides of the main shaft 24. Rotating shafts 30 are rotatably connected to both ends of the rotating beams 29. A liquid-holding tank 32 is fixedly connected to the end of the rotating shaft 30 closest to the center of the mixing tank 10. The liquid-holding tank 32 has a semi-circular cross-section, and its center of gravity is near the bottom, ensuring that the opening of the liquid-holding tank 32 always faces upwards under gravity. A driven gear 31 is installed at the end of the rotating shaft 30 furthest from the mixing tank 10, and an arc-shaped gear ring is installed on the front side of the inner wall of the mixing tank 10. 34. When the driven gear 31 rotates to the front of the mixing tank 10, it will mesh with the arc-shaped toothed ring 34 for transmission. The number of teeth of the arc-shaped toothed ring 34 is greater than half the number of teeth of the driven gear 31. That is to say, from the moment the driven gear 31 starts to rotate after contacting the arc-shaped toothed ring 34 until it disengages from the arc-shaped toothed ring 34, the entire driven gear 31 rotates more than 180°. At this time, due to the action of gravity, the liquid tank 32 will continue to drive the driven gear 31 to continue rotating until the center of gravity of the liquid tank 32 rotates to a downward state. That is to say, the liquid tank 32 rotates with the opening facing upward until the driven gear 31 contacts the arc-shaped toothed ring 34. Then, the entire liquid tank 32 will rotate a full circle so that the opening faces upward again.

[0037] In one embodiment, a disturbance rod 35 is provided at the bottom of the liquid-containing tank 32, and a lever 33 that cooperates with the driven gear 31 is provided at the bottom of the mixing tank 10. Multiple disturbance rods 35 are evenly distributed from left to right at the bottom of the liquid-containing tank 32. By setting the disturbance rods 35, the center of gravity of the liquid-containing tank 32 is lowered, ensuring that the liquid-containing tank 32 can maintain an upward-facing opening under the action of gravity. Furthermore, levers 33 are installed at the bottom of both sides of the mixing tank 10. Therefore, when the driven gear 31 rotates to the bottom of the mixing tank 10, it will contact the levers 33. As the driven gear 31 rotates around the center of the mixing tank 10, it will also rotate. When the driven gear 31 disengages from the levers 33, it will return to its initial position under the influence of gravity. In other words, when the driven gear 31 contacts the levers 33, the liquid container 32 will sway back and forth. This swaying of the liquid container 32 will stir the liquid inside the mixing tank 10 through the agitator 35. A second drive motor 27 is installed at the lower left end of the mixing tank 10. The output shaft of the second drive motor 27 is fixedly connected to a third bevel gear 25. The third bevel gear 25 meshes with a fourth bevel gear 26, which is fixedly connected to the left end of the main shaft 24.

[0038] In one embodiment, the base 1 has front-to-back oriented sliding grooves 15 on its left and right sides. Sliding blocks 4 are slidably connected to the front and back sides of the sliding grooves 15. The upper surface of the sliding blocks 4 is rotatably connected to the lower end of a support rod 5. The upper end of the support rod 5 is rotatably connected to the front and back sides of a rotating seat 7. The middle of the rotating seat 7 is rotatably connected to the middle of a suspension rod 9. A left-to-right oriented drive rod 16 is provided on the rear side of the upper surface of the base 1. First bevel gears 18 are provided at both ends of the drive rod 16. The first bevel gears 18 mesh with a second bevel gear 17. The second bevel gear 17 is fixedly connected to the rear end of a front-to-back oriented lead screw 14. The lead screw 14 has threads with opposite directions on its front and back sides. The middle part of the front and rear threaded connection of the slider 4 is driven by the drive rod 16, which can drive the two lead screws 14 to rotate simultaneously. When the lead screws 14 rotate, they can drive the sliders 4 to move closer or further apart. When the sliders 4 move closer together, they will push the rotating seat 7 to move upward through the support rod 5. When the sliders 4 move further apart, they will cause the rotating seat 7 to move downward. Therefore, when the lead screws 14 rotate, the mixing tank 10 will move up and down. A first drive motor 19 is set on the rear side of the upper surface of the base 1. The output shaft of the first drive motor 19 is fixedly connected to the first pulley 20. The first pulley 20 is connected to the second pulley 22 through the synchronous belt 21. The second pulley 22 is fixedly connected to the middle part of the drive rod 16.

[0039] In one embodiment, the water bath 11 has clearance grooves 13 on both sides to mate with the mixing tank 10. The water bath 11 is a box structure with an open top. Arc-shaped clearance grooves 13 are provided at both ends of the water bath 11, so that the bottom of the cylindrical mixing tank 10 fits well with the clearance grooves 13 after it is lowered. Flat, front-to-back oriented heat-conducting fins 28 are provided on the outer side of the bottom of the mixing tank 10. Both the mixing tank 10 and the heat-conducting fins 28 are made of heat-conducting material, and the front and back sides of the heat-conducting fins 28 are vertical planes. Left-to-right oriented baffles 12 are provided on the front and back sides above the water bath 11. The distance between the two baffles 12 is exactly the front-to-back width of the heat-conducting fins 28. Therefore, when the heat-conducting fins 28 are inserted into the water bath 11, they fall precisely between the two baffles 12, keeping the mixing tank 10 in an upward position without swaying back and forth.

[0040] In this embodiment, the base 1 is placed stably on a table or the ground. First, the first drive motor 19 is started. The first drive motor 19 drives the mixing tank 10 to move downward through the lead screw 14. The mixing tank 10 lands at the bottom of the water bath 11. At this time, the throttle valves of the two feed ports 23 can be opened. Concentrated sulfuric acid is added to the mixing tank 10 through one feed port 23. The concentrated sulfuric acid can be diluted later. The water level of the concentrated sulfuric acid is lower than the arc-shaped toothed ring 34.

[0041] Alternatively, another inlet 23 can be connected to the relevant purified water output device. By setting two inlets 23, the purified water and concentrated sulfuric acid will not contaminate each other during feeding. Furthermore, during feeding, the other inlet 23 can be used for venting, allowing the liquid to be added normally.

[0042] The second drive motor 27 is started, and it drives the main shaft 24 to rotate via gear transmission. Viewed from the right, the main shaft 24 begins to rotate clockwise. When the main shaft 24 drives the rotating beam 29 to rotate, the rotating beam 29 drives the liquid collection tank 32 to rotate to the top of the mixing tank 10. At this point, the main shaft 24 stops, and purified water is added to the liquid collection tank 32 through the feed inlet 23. After the purified water is added, the main shaft 24 continues to rotate, and the rotating beam 29 drives the liquid collection tank 32 to rotate towards the rear of the mixing tank 10. As the tank 32 continues to move downwards, it falls into the concentrated sulfuric acid inside the mixing tank 10, ensuring that the top side of the tank 32 is just below the surface of the concentrated sulfuric acid. This allows a small amount of concentrated sulfuric acid to flow into the tank 32, where it mixes with the purified water. Due to the small amount of concentrated sulfuric acid, the heat generated during mixing is minimal. As the tank 32 slowly moves downwards, the concentrated sulfuric acid gradually enters and mixes with the purified water. Once the tank 32 is completely submerged in the concentrated sulfuric acid inside the mixing tank 10, the concentrated sulfuric acid... The purified water in container 32 will be completely mixed with concentrated sulfuric acid. When container 32 moves below mixing tank 10, driven gear 31 contacts lever 33, causing container 32 to sway back and forth. Agitator 35 stirs and mixes the concentrated sulfuric acid inside mixing tank 10. When driven gear 31 moves to the front of mixing tank 10, it contacts arc-shaped gear ring, causing container 32 to flip, thus completely pouring the remaining liquid in container 32 into mixing tank 10. 2. After rotating once, the liquid tank 32 will be empty. At this time, the liquid tank 32 will move to the top of the mixing tank 10 again. The liquid tank 32 is waiting for the addition of purified water. As the liquid tank 32 continues to rotate, the purified water can be intermittently added into the mixing tank 10 to dilute the concentrated sulfuric acid. After the purified water is added, the feed port 23 can be closed. At this time, the rotation speed of the liquid tank 32 can be increased. The rotating liquid tank 32 can stir the liquid inside the mixing tank 10, thereby realizing the mixing of the acid solution.

[0043] After the acid solution is mixed, the first drive motor 19 is started. The first drive motor 19 drives the mixing tank 10 to move upward through the lead screw 14. The mixing tank 10 is separated from the water bath 11. At this time, the mixing tank 10 can be manually flipped so that the feed port 23 of the mixing tank 10 is rotated downward. At this time, the feed port 23 can be matched with the relevant support container so that the mixed acid solution can be discharged into the support container.

[0044] This invention relates to an acid preparation device for battery production. Through a liquid holding tank 32 that can rotate around a mixing tank 10, purified water can be intermittently added to the concentrated sulfuric acid inside the mixing tank 10 for dilution. The batch addition allows the heat generated by the dilution of concentrated sulfuric acid to be discharged in a timely manner, avoiding the generation of water vapor.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
