Technical Field
[0001] This utility model relates to the technical field of water treatment experimental equipment, and in particular to a simplified experimental device for flocculant synthesis and turbidity testing. Background Technology
[0002] In the field of water treatment research, the synthesis and performance testing of flocculants are crucial steps in evaluating their application effectiveness. Traditional experimental methods typically involve a series of complex procedures: first, the required chemical raw materials are added to a beaker, and then the pH of the solution is adjusted to suit the reaction conditions; next, source water and flocculant are added and thoroughly mixed using a magnetic stirrer to ensure the flocculant is uniformly dispersed throughout the solution system; subsequently, the mixture is allowed to stand for a period of time to allow flocs to form and settle; finally, a sample is taken from the solution, and the turbidity of the supernatant is measured using equipment such as a turbidimeter to evaluate the flocculation effect. This series of steps is not only cumbersome, but each step also requires precise control; any slight operational error can affect the final experimental results, reducing the accuracy and reliability of the experimental data.
[0003] Furthermore, traditional experimental methods lack effective filtration measures during sampling, which can easily lead to insoluble matter or incompletely settled flocs entering the turbidimeter sample bottle, interfering with test results and further affecting the accuracy of experimental conclusions. This data deviation due to impurities is particularly pronounced when analyzing samples requiring high precision and sensitivity. Therefore, simplifying experimental procedures, reducing human error, and improving the accuracy and reliability of experimental results have become urgent problems to be solved in the field of water treatment research.

[0030] Example 1
[0031] Please refer to Figures 1-2This utility model provides a simplified experimental device for flocculant synthesis and turbidity testing, including a beaker 1.

The lower end of the handle is made of borosilicate glass. A silicone sealing ring is set at the lower end of the borosilicate glass. The lower end of the silicone sealing ring is made of polytetrafluoroethylene.
[0035] An installation port 3 is provided on one side of the beaker 1. A sampling valve 11 is installed in the installation port 3 to control the flow rate of the sampling liquid. The valve 11 is located on the side of the beaker 1 and at a height of 1 / 3 from the bottom of the beaker 1 to ensure that clear liquid can be obtained. An outlet 12 is provided at the lower end of the valve 11.
[0036] Furthermore, a filter assembly is threadedly installed at the liquid inlet end of valve 11. The filter assembly includes a filter cylinder 15 threadedly connected to the liquid inlet end of valve 11. One end of the filter cylinder 15 has multiple coarse filter holes 16 to filter larger impurities in the liquid.
[0037] A microporous filter membrane 14 is installed inside the filter cartridge 15. The pore size of the microporous filter membrane 14 is 0.45μm, and it is made of polytetrafluoroethylene. The microporous filter membrane 14 prevents insoluble substances from interfering with the test results and improves the accuracy of the experimental results.
[0038] Furthermore, sealing rings 313 are fitted on both the inner and outer sides of the installation port 3 to prevent the liquid inside the beaker 1 from leaking out.
[0039] The end of the filter cylinder 15 is provided with a hexagonal fixing member to press the sealing ring 3 13 on the inner wall of the beaker.

[0040] The microporous filter membrane 14 can be cut to a suitable size, placed on the microporous filter membrane fixing part inside the filter cylinder 15, and then the filter cylinder 15 is tightened with the valve 11 by thread to clamp the microporous filter membrane 14. The clamping method is used to facilitate the replacement later.
[0041] The experimental procedure for flocculant synthesis is as follows:
[0042] Preparation: Install the sealing cap 6 on beaker 1, add polysilicic acid and polyaluminum chloride through the liquid inlet 7 respectively, and then adjust the pH value through the liquid inlet 7.

[0047] Stirring: Place a magnetic stir bar inside beaker 1, place beaker 1 on an external magnetic stirrer, and stir at the set stirring speed.
[0048] Settle: After stirring, turn off the magnetic stirrer and let it settle.
[0049] Sampling: Open the sampling valve 11, filter the sample through the microporous filter membrane 14, and add the sample directly into the turbidimeter sample bottle.
[0050] Test: Place the turbidimeter sample bottle into the turbidimeter to perform a turbidimetric test.
[0051] Example 2
[0052] As can be seen from the above embodiments, the experimental equipment uses the filter cartridge 15 and the microporous filter membrane 14 for filtration to prevent impurities from clogging the coarse filter pores 16. Further improvements to the above embodiments are possible, such as... Figures 3 to 8 As shown, a sliding sleeve 18 is slidably mounted on the valve 11 located on one side of the sealing ring 13. Sliding rods 19 are fixedly mounted on both sides of the sliding sleeve 18. The sliding rods 19 pass through the sliding hole 131 opened on the sealing ring 13 and the end of the filter cylinder 15 and are connected to the filter plate 17. The filter plate 17 is slidably connected to the coarse filter hole 16. During normal use, the filter plate 17 and the coarse filter hole 16 maintain a certain distance. The filter plate 17 can also block impurities in the liquid to a certain extent. At the same time, when there are impurities in the coarse filter hole 16, the sliding sleeve 18 can be slid, and the sliding rod 19 moves the filter plate 17 into the coarse filter hole 16, pushing the impurities into the filter cylinder 15.
[0053] Secondly, a positioning sleeve 20 is fixedly installed on the valve 11 located on one side of the sliding sleeve 18. A screw 21 is rotatably installed on both sides of the positioning sleeve 20. An extension sleeve 4 is installed on the outside of the mounting port 3. Threaded holes 5 are symmetrically opened on both sides of the extension sleeve 4. One end of the screw 21 is threadedly connected to the threaded hole 5. The valve 11 is fixed to the side of the beaker 1 by the screw 21, thereby improving the stability of the valve 11.
[0054] In summary, the simplified experimental device for flocculant synthesis and turbidity testing according to this utility model works as follows: the sealing cap 6 is installed on the beaker 1, and liquid is added through the liquid inlet 7. The liquid can be filtered through the microporous filter membrane 14 and the filter cylinder 15, and sampled through the valve 11. Large particulate impurities in the liquid are filtered through the filter cylinder 15 and the coarse filter hole 16. At the same time, the filter plate 17, which has a certain distance from the coarse filter hole 16 during use, blocks the impurities to a certain extent, reducing the impurities from clogging the coarse filter hole 16. Secondly, by sliding the sliding sleeve 18, the sliding rod 19 can carry the filter plate 17 into the coarse filter hole 16, pushing the clogging impurities into the filter cylinder 15.
