[0027] like Figure 1-7 As shown, the present invention has the following specific embodiments.

[0028] Example 1

[0029] A quantitative sampling polyaluminum chloride concentration detection device includes a support platform 1. Support legs 2 are symmetrically fixed to the four corners of the bottom of the support platform 1. A fixed column 3 is fixed to the center of the upper surface of the support platform 1. A support plate 4 is fixed to the top of the fixed column 3. Several quantitative sampling components are equidistantly arranged on the support plate 4. Rotary shafts 13 are rotatably connected to the upper side of the support platform 1 at positions corresponding to the quantitative sampling components. A fixed seat 14 is fixed to the top of the rotating shaft 13. A detection box 24 is detachably connected to the fixed seat 14. The detection box 24 is made of transparent material to facilitate observation of indicator color changes. The top of the detection box 24 has an open structure, and a retaining ring 25 is fixed to the top edge to prevent solution spillage. A notch 26 is provided on the retaining ring 25 to facilitate pouring out the solution. A cavity is formed inside the support platform 1. A drive assembly for driving the several rotating shafts 13 to rotate synchronously is provided on the support platform 1.

[0030] In this embodiment, as Figure 1-7As shown, indicators are pre-added to each detection box 24. The detection box 24 is installed on the fixing base 14. The corresponding sample solution is quantitatively measured by several quantitative sampling components and added to the corresponding detection box 24. Multiple sample solutions can be detected at the same time, improving detection efficiency. The detection box 24 is rotated by the driving component to accelerate the mixing of the indicator and the polyaluminum chloride solution to be tested in the detection box 24. Then, titrant is added to the detection box 24 using a burette until the indicator changes color, indicating that the titration endpoint has been reached. The amount of titrant consumed is recorded, and the concentration of the solution to be tested is calculated according to the reaction equation of the titrant and polyaluminum chloride. The detection box 24 is easy to install and remove, and can be easily replaced for multiple tests.

[0031] Example 2

[0032] The quantitative sampling assembly includes a piston cylinder 5 fixed to the upper side of a support plate 4. The piston cylinder 5 is made of transparent material and has graduations on its outer side. A piston rod 6 is installed inside the piston cylinder 5. A piston is fixed to the bottom of the piston rod 6 and slides inside the piston cylinder 5. A connecting plate 7 is fixed to the top of several piston rods 6. The connecting plate 7 has a circular structure and a handle 8 is fixed to its top side. An outlet pipe 12 is fixed to the bottom of the piston cylinder 5 and extends to the bottom of the support plate 4. An outlet check valve that only allows liquid to flow out of the piston cylinder 5 is installed on the outlet pipe 12. A fixing plate 9 is fixed to the outside of the piston cylinder 5 on the support plate 4. A liquid storage tank 10 is fixed to the fixing plate 9. The top of the liquid storage tank 10 has an open structure. A connecting pipe 11 is fixed between the bottom of the liquid storage tank 10 and the corresponding piston cylinder 5. An inlet check valve that only allows liquid to flow into the piston cylinder 5 is installed on the connecting pipe 11.

[0033] In this embodiment, as Figure 1 , 2 As shown in Figure 3, the polyaluminum chloride solution to be tested is poured into each storage tank 10. By pulling the connecting plate 7 upward with the handle 8, each piston rod 6 moves upward synchronously. The piston slides upward along the inner wall of the piston cylinder 5, drawing the solution in the storage tank 10 into the piston cylinder 5 through the connecting pipe 11. Then, the connecting plate 7 is pressed down, and each piston rod 6 moves downward synchronously. The piston slides downward along the inner wall of the piston cylinder 5, pressing the extracted solution into the detection box 24 through the outlet pipe 12.

[0034] Example 3

[0035] The drive assembly includes a drive shaft 16 rotatably connected to the center of the cavity of the support platform 1. A drive gear 17 is fixedly connected to the drive shaft 16. The bottom end of the rotating shaft 13 extends into the cavity of the support platform 1 and is fixedly connected to a driven gear 15. The driven gears 15 mesh with the drive gear 17. A drive motor 18 is fixedly connected to the bottom of the support platform 1 at the position corresponding to the drive shaft 16. The output end of the drive motor 18 is fixedly connected to the drive shaft 16.

[0036] In this embodiment, as Figure 3 , 4 As shown in Figure 5, the drive motor 18 is started, which drives the transmission shaft 16 and the drive gear 17 to rotate, which in turn drives the driven gear 15 meshing with it to rotate. Consequently, the rotating shaft 13, the fixed seat 14 and the installed detection box 24 rotate accordingly, which accelerates the mixing of the indicator and the polyaluminum chloride solution to be tested in the detection box 24, improves the uniformity, and accelerates the reaction mixing during subsequent titration.

[0037] Example 4

[0038] The fixed base 14 has a T-shaped slot 19. The bottom of the detection box 24 is fixedly connected to a T-shaped plug 27 that is compatible with the T-shaped slot 19. The T-shaped plug 27 is inserted into the T-shaped slot 19. A locking component for limiting the T-shaped plug 27 is provided on one side of the fixed base 14. The locking component includes a screw 20 rotatably connected to the fixed base 14 and a guide rod 22 fixedly connected to the fixed base 14. A limit plate 23 is threadedly connected to the screw 20. The limit plate 23 has an L-shaped structure and is slidably connected to the guide rod 22. A knob 21 is fixedly connected to the outer end of the screw 20.

[0039] In this embodiment, as Figure 1 , 2 As shown in Figures 5 and 7, an indicator is added to each test box 24 beforehand. Then, the T-shaped insert 27 on the bottom side of the test box 24 is inserted into the T-shaped slot 19 of the fixing base 14. The corresponding knob 21 is rotated, thereby driving the corresponding screw 20 to rotate, thereby driving the limiting plate 23 to move along the guide rod 22 toward the fixing base 14 until it abuts against the outside of the T-shaped slot 19, locking the T-shaped insert 27 in the T-shaped slot 19, thereby installing the test box 24 on the fixing base 14. The test box 24 is easy to install and remove, and easy to replace for multiple tests.

[0040] The working principle of this utility model is as follows: Indicator is added to each detection box 24 beforehand. Then, the T-shaped insert 27 on the bottom side of the detection box 24 is inserted into the T-shaped slot 19 of the fixing base 14. Rotating the corresponding knob 21 causes the corresponding screw 20 to rotate, thereby moving the limiting plate 23 along the guide rod 22 towards the fixing base 14 until it abuts against the outside of the T-shaped slot 19, locking the T-shaped insert 27 in the T-shaped slot 19. Thus, the detection box 24 is installed on the fixing base 14. Simultaneously, the polyaluminum chloride solution to be tested is poured into each storage tank 10. By pulling the connecting plate 7 upwards with the handle 8, each piston rod 6 moves upwards synchronously. The piston slides upwards along the inner wall of the piston cylinder 5, drawing the solution in the storage tank 10 into the piston cylinder 5 through the connecting pipe 11. Then, the connecting plate 7 is pressed down. Each piston rod 6 moves down synchronously, and the piston slides down along the inner wall of the piston cylinder 5, pressing the extracted solution through the outlet pipe 12 into the corresponding detection box 24. At the same time, multiple sample solutions can be measured to improve sampling efficiency. The drive motor 18 is started, which drives the transmission shaft 16 and the drive gear 17 to rotate, which in turn drives the driven gear 15 meshing with it to rotate. Then the rotating shaft 13, the fixed seat 14 and the installed detection box 24 rotate accordingly, accelerating the mixing of the indicator and the polyaluminum chloride solution to be tested in the detection box 24 and improving uniformity. Then, the titrant is added to the detection box 24 using a burette until the indicator changes color, indicating that the titration endpoint has been reached. The amount of titrant consumed is recorded, and the concentration of the solution to be tested is calculated according to the reaction equation of the titrant and polyaluminum chloride.
