[0018] 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.
[0019] Reference Figures 1-5This utility model provides an embodiment of an online detection and mixing device for polycarboxylate additives, comprising: a mixing tank 1; a motor 6, the motor 6 being disposed at the top of the mixing tank 1; a rotating rod 7, the top of the rotating rod 7 being fixedly connected to the output end of the motor 6, and the bottom of the rotating rod 7 being rotatably connected to the inside of the mixing tank 1; a fixing block 8, the fixing block 8 being fixedly connected to the outside of the rotating rod 7; a push block 9 and a push rod 10, the push block 9 being slidably connected to the inside of the fixing block 8, and the push rod 10 being fixedly connected to the right side of the outside of the push block 9; a scraper 11 and a spring 12, the scraper 11 being fixedly connected to the outside of the push rod 10, the scraper 11 being in contact with the inner wall of the mixing tank 1, and the spring 12 being fixedly connected to the left side of the outside of the push block 9; and a filter assembly, the filter assembly being used to filter the liquid added into the mixing tank 1, wherein fixing blocks 14 are fixedly connected to both sides of the lower part of the rotating rod 7, and connecting rods are fixedly connected to the outer perimeter of the two fixing blocks 14. A connecting rod 15 is attached to multiple connecting rods 15, and stirring rods 16 are fixedly connected to both sides of the outside. A detection tube 27 is installed on the top left side of the mixing tank 1, and a detector 28 is set at the bottom of the detection tube 27. During detection, the liquid inside the mixing tank 1 is transported to the detector 28 through the detection tube 27, and the liquid is detected by the detector 28. An installation ring 5 is fixedly connected to the top of the mixing tank 1, and a motor 6 is fixedly connected inside the installation ring 5. The installation ring 5 is used to fix the motor 6. Support legs 2 are fixedly connected to the lower part of the mixing tank 1 around the perimeter. The support legs 2 are used to improve the stability of the mixing tank 1. A sliding hole 13 is opened on the right side of the inside of the fixing block 1 8. The push rod 10 is slidably connected inside the sliding hole 13. The sliding hole 13 is used to facilitate the movement of the push rod 10. A discharge port 3 is fixedly connected to the bottom of the mixing tank 1. A valve is set outside the discharge port 3. The discharge port 3 is used to facilitate the discharge of the liquid inside the mixing tank 1.
[0020] Specifically, during the mixing of reagents and stock solution, firstly, through the feed inlet 4 located at the top of the equipment, a predetermined ratio of chemical reagents and stock solution are sequentially added into the mixing tank 1. After the materials are added, the motor 6 is started. After the motor 6 starts, the rotating rod 7 fixedly connected to its output end begins to rotate. As the rotating rod 7 rotates, the fixing blocks 14 fixed on both sides of its lower end also rotate synchronously. During the rotation of the fixing blocks 14, multiple connecting rods 15 evenly arranged around its outer perimeter are driven to rotate together. The rotation of the connecting rods 15 further drives the stirring rods 16 fixed on both sides to rotate inside the mixing tank 1. The stirring rods 16 continuously rotate and agitate the liquid in the tank, causing the stock solution and reagents to mix evenly, thereby improving the mixing efficiency and the uniformity of the material reaction. At the same time, while the rotating rod 7 rotates, it also drives the upper external fixed blocks 16 to rotate. The fixed block 8 rotates synchronously. During the rotation of the fixed block 8, it drives the push block 9, which is installed inside it in a sliding connection, to move. When the push block 9 moves, it drives the externally fixed push rod 10 to move together. As the push rod 10 moves, the scraper 11 connected to it also scrapes back and forth on the inner wall surface of the mixing tank 1, thereby removing the residual liquid adhering to the tank wall. In order to ensure that the scraper 11 is always in close contact with the inner wall of the mixing tank 1 during the movement, a spring 12 is set inside the fixed block 8. The spring 12 allows the scraper 11 to achieve a tight fit with the tank wall in any position. Through the cooperation of the above structure, the mixing of the stock solution and reagents is realized inside the mixing tank 1. Moreover, the tank wall can be automatically scraped and cleaned at the same time as mixing, avoiding material waste and cross-contamination, thereby further improving the accuracy of subsequent testing and the quality stability of the mixing process.
[0021] Reference Figures 2-6 The filter assembly includes an inlet 4, which is fixedly connected to the top right side of the mixing tank 1. A filter shell 17 is fitted over the inlet 4, and a filter plate 18 is installed inside the filter shell 17. An installation cavity 20 is opened on the lower right side of the filter shell 17, and a movable block 21 is slidably connected inside the installation cavity 20. An original insert block 24 is fixedly connected to the left side of the movable block 21, and a pull rod 22 is fixedly connected to the right side of the movable block 21. The pull rod 22 facilitates the operation of the operator. There is a spring 23. A through hole 25 is opened on the right side of the inside of the filter shell 17. The pull rod 22 is slidably connected inside the through hole 25. The through hole 25 facilitates the movement of the pull rod 22. A through hole 26 is opened on the left side of the inside of the filter shell 17. The insert block 24 is slidably connected inside the through hole 26. The through hole 26 facilitates the movement of the insert block 24. A slot 19 is opened on the right side of the outside of the feed port 4. The insert block 24 is inserted into the slot 19, which improves the stability of the filter shell 17 installation.
[0022] Specifically, during the installation of the filter structure, firstly, pull rod 22 is pulled. The top of pull rod 22 is fixedly connected to the sliding block 21 inside. As pull rod 22 is pulled outward, the sliding block 21 moves inside the mounting cavity 20. During the sliding process, the sliding block 21 drives the externally fixed insertion block 24 on its left side to move synchronously. At the same time, during the pulling process, it exerts a squeezing effect on spring 23, causing spring 23 to deform under force. Then, when the insertion block 24 moves to the position of the through hole 25 opened in the mounting cavity 20, the filter shell 17 can be fitted onto the outside of the feed inlet 4. The filter shell 17 is equipped with a filter plate 18 inside for filtering the added liquid. After the filter housing 17 is installed in place, release the pull rod 22. Under the restoring force of the spring 23, the pull rod 22 will spring back, causing the insert block 24 to be inserted into the slot 19 on the right side of the feed inlet 4, thus completing the installation of the filter housing 17. After installation, the operator can pour the liquid materials to be added to the mixing tank 1 into the upper inlet of the filter housing 17 in sequence. When the liquid flows through the internal filter plate 18 under the action of gravity, the filter plate 18 can intercept particles, impurities or other foreign objects mixed in the liquid. The filtered liquid smoothly enters the interior of the mixing tank 1 through the feed inlet 4, reducing the interference of foreign objects on the mixing process and improving the purity and performance stability of the final product.
[0023] Working principle: When mixing reagents and stock solutions, firstly, the reagents and stock solutions are added into the mixing tank 1 through the feed inlet 4. Then, the motor 6 is started. The motor 6 drives the rotating rod 7 fixed at the output end to rotate. The rotation of the rotating rod 7 drives the fixed blocks 14 fixed on both sides at the bottom to rotate. The rotation of the fixed blocks 14 drives the connecting rods 15 fixed on the outer perimeter to rotate. The rotation of the multiple connecting rods 15 drives the stirring rods 16 fixed on both sides to rotate inside the mixing tank 1. The rotation of the stirring rods 16 mixes the reagents and stock solutions. At the same time, the rotation of the rotating rod 7 drives the fixed blocks 14 to rotate. 8 rotates, and the rotation of the fixed block 8 moves the internally slidably connected push block 9. The movement of the push block 9 moves the externally fixed push rod 10. The movement of the push rod 10 moves the externally fixed scraper 11. The movement of the scraper 11 facilitates the scraping of the liquid adhering to the inner wall of the mixing tank 1. At the same time, the spring 12 installed inside the fixed block 8 ensures that the scraper 11 is always in contact with the inside of the mixing tank 1. This makes it easy to scrape off the liquid adhering to the inside of the mixing tank 1 when mixing reagents and stock solutions, so that the stock solution and reagents are fully mixed, thereby improving the accuracy of subsequent test results and the quality of the mixing ratio. When installing the filter structure outside the feed inlet 4, firstly, pull the lever 22 to move the top-fixed movable block 21 inside the mounting cavity 20. As the movable block 21 moves, it also moves the external left-fixed insert block 24. Simultaneously, as the lever 22 moves, it compresses the externally sleeved spring 23, causing the spring 23 to deform under force. Then, when the insert block 24 moves into the through hole 25, the filter shell 17 is fitted onto the outside of the feed inlet 4. Finally, the lever 22 is released, and the spring 23... Under the reaction force, the insert 24 is inserted into the slot 19 opened on the right side of the feed inlet 4, thus completing the installation of the filter shell 17. Then, the liquid to be added is poured into the filter shell 17, and the liquid is filtered by the filter plate 18 installed inside the filter shell 17. Finally, the filtered liquid enters the interior of the mixing tank 1 through the feed inlet 4. This realizes the installation of a filter structure on the outside of the feed inlet 4 of the mixing equipment, reducing the interference of foreign objects on the mixing process and improving the purity and performance stability of the final product.
