[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: This implementation aims to address the problem that adding acid or alkali solutions to the tank requires manual control, which may lead to errors and make it impossible to accurately control the ratio of acid or alkali solutions to wastewater, thus reducing the accuracy of the mixing ratio. Please refer to [link to relevant documentation]. Figures 1-5A pH adjustment device includes a support base 1, an adjustment tank 2, a cover plate 3, a drain valve 8, and an automatic dosing structure. The adjustment tank 2 is fixedly connected to the support base 1. An anti-slip pad 23 is provided at the bottom of the support base 1 to increase the overall stability of the device. Two observation plates 22 are embedded in the adjustment tank 2, allowing for easy observation of the internal conditions and monitoring of the pH adjustment progress. The top of the adjustment tank 2 is covered by the cover plate 3. A support frame 4 is installed at the bottom of the support base 1, and a motor 5 is mounted on the support frame 4. The motor 5 is a servo motor, which has rapid start-stop and acceleration capabilities and maintains stable output torque. The output shaft of the motor 5 is connected to a rhomboid rod 6 via a coupling. The rhomboid rod 6 has a hexagonal cross-section. A stirring paddle 7 is slidably and rotatably installed inside the adjustment tank 2. The stirring paddle 7 consists of an inner stirring plate and an outer stirring rod. The outer stirring rod is spiral-shaped and closely attached to the inner wall of the adjustment tank 2. The inner stirring plate effectively pushes the material from the center outwards, while the outer spiral stirring rod lifts the material upwards along the tank wall. The materials form a circulating flow, which helps to accelerate the mixing speed between materials and improve mixing efficiency. The outer stirring rod can effectively scrape off the material on the tank wall, preventing the material from adhering to the tank wall and forming dead corners, ensuring that all wastewater and drugs can participate in the mixing process. The bottom of the stirring paddle 7 has a hexagonal hole, which is engaged with the rhomboid rod 6, and the stirring paddle 7 can slide up and down along the rhomboid rod 6. The bottom of the regulating tank 2 is equipped with a drain valve 8, and the bottom of the support base 1 is fixedly connected to the mounting plate 18. A convex ring 19 is fixedly connected to the 8, and a connecting frame 20 is fixedly connected to the stirring paddle 7. A contact ring 21 is fixedly connected to the outside of the connecting frame 20. The contact ring 21 moves on the convex ring 19. The upper end face of the convex ring 19 is an arc-shaped inclined surface and contacts the lower end face of the contact ring 21. The distance that the stirring paddle 7 moves upward is the height difference between the highest and lowest points of the upper end face of the convex ring 19. This distance is less than the distance at which the stirring paddle 7 and the rhomboid rod 6 are engaged and overlapped. The downward movement is caused by the contact ring 21 driving the connecting frame 20 and the stirring paddle 7 to move downward and reset.

[0025] Please see Figure 4 and Figure 5 A mounting bracket 9 is fixedly connected to the cover plate 3. Two ring weighing devices 10 are installed on the mounting bracket 9. The ring weighing devices 10 are weighing sensors of model RLC-28T. A display screen 11 is installed on the front side of the mounting bracket 9. A storage tank 12 is placed inside the ring weighing device 10. An electric control valve 13 is installed at the bottom of the storage tank 12.

[0026] When it is necessary to adjust the pH of wastewater, firstly, the annular weighing device 10 and display screen 11 are used to inject wastewater into the left storage tank 12. The annular weighing device 10 weighs the wastewater in the left storage tank 12, and the weighing data is displayed on the display screen 11. Then, the medicine is injected into the right storage tank 12, and the annular weighing device 10 weighs the medicine, and the weighing data is displayed on the display screen 11. When the medicine and wastewater reach a specific ratio, the injection of medicine is stopped, thereby achieving the purpose of automatic proportioning, improving the proportioning accuracy and pH adjustment effect. Then, the electric control valve 13 is opened to allow wastewater and medicine to enter the adjustment tank 2. Subsequently, the motor 5 is turned on. The output shaft of the motor 5 rotates, driving the rhomboid rod 6 to rotate. The rotation of the rhomboid rod 6 causes the stirring paddle to rotate. 7. When the stirring paddle 7 rotates, it drives the connecting frame 20 and the contact ring 21 to rotate together, causing the contact ring 21 to move upward along the inclined surface of the convex ring 19, thus moving the connecting frame 20 and the stirring paddle 7 upward. The contact ring 21 continues to rotate and moves downward along the inclined surface of the convex ring 19, causing the connecting frame 20 and the stirring paddle 7 to move downward and reset, thereby realizing the up-and-down movement of the stirring paddle 7. Through this up-and-down movement, the medicine circulates after entering the regulating tank 2, is quickly mixed and diffused to all parts of the regulating tank 2, so that the wastewater and the medicine are fully mixed, so as to avoid the pH value error in the regulating tank 2 and improve the pH value regulation effect of the wastewater. After the pH value of the wastewater is regulated, the motor 5 is turned off and the drain valve 8 is opened to discharge the regulated wastewater.

[0027] Example 2: Based on Example 1, please refer to... Figure 2 and Figure 3 A bracket 14 is fixedly connected to the cover plate 3. A detector 15 is installed on the bracket 14. A detection rod 16 is connected to the bottom of the detector 15. The detection rod 16 extends into the regulating tank 2. Two warning lights 17 are installed on the detector 15. A sealing ring 24 is installed on the cover plate 3. The sealing ring 24 wraps around the upper end of the detection rod 16 and reduces the gap between the detection rod 16 and the cover plate 3.

[0028] When using this device, turn on the detector 15 so that the detection rod 16 can detect the wastewater inside the regulating tank 2. When the pH of the wastewater reaches the normal value, the detector 15 controls the warning light 17 to light up, thereby reminding the staff to open the drain valve 8 in time to improve the pH regulation efficiency.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
