Environmental engineering experiments, as a fundamental part of environmental engineering teaching, are an important way to enhance the practical skills of graduates in this field. To achieve both effective and high-quality teaching in environmental engineering courses, innovative and diverse experimental setups and scientifically efficient teaching methods are complementary and indispensable.

[0003] In university experimental teaching, when purifying rainwater or sewage, students need to place various filtration and purification media inside the experimental device, such as pebbles, small gravel, coarse sand, and fine sand.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 7 As shown, a combined water purification experimental device includes: a support 1, an arc-shaped box 2, an arc-shaped cover 3, an outlet pipe 4, an inlet pipe 5, a filter assembly 6, a locking assembly 7, and a hinge 8.

[0032] Multiple brackets 1 are fixedly mounted on top of an arc-shaped box 2. An arc-shaped cover 3 is rotatably mounted on the arc-shaped box 2 via a hinge 8. A water outlet pipe 4 is fixedly mounted on the bottom of the arc-shaped box 2. A water inlet pipe 5 is fixedly mounted on the top of the arc-shaped box 2. Multiple filter components 6 are fixedly mounted inside the arc-shaped box 2. A locking component 7 is fixedly mounted on the arc-shaped box 2 and the arc-shaped cover 3. Different filter media are arranged and assembled inside the arc-shaped box 2 through multiple filter components 6 to filter sewage.

[0033] Multiple brackets 1 are securely installed with arc-shaped boxes 2 by means of bolts or other means. The curvature of the arc-shaped cover 3 is perfectly matched with that of the arc-shaped box 2, and when closed, it can form a complete sealed cavity with the arc-shaped box 2 to prevent sewage leakage.

[0034] The outlet pipe 4 ensures that the filtered clean water can be discharged smoothly; the sewage or rainwater to be filtered can be injected into the arc-shaped box 2 at a uniform speed through the inlet pipe 5.

[0035] Multiple filter components 6 are fixedly installed inside the arc-shaped box 2. These filter components 6 are arranged in sequence according to the filtration order set in the experiment. Each filter component 6 can hold different types of filter media, such as activated carbon, quartz sand, filter cotton, ion exchange resin, etc. The structural design of the filter components 6 is easy to disassemble and assemble, allowing the experimenters to flexibly adjust the type, combination order and filling amount of filter media according to different purification needs. The locking component 7 is fixedly installed at the corresponding position of the arc-shaped box 2 and the arc-shaped cover 3. When the arc-shaped cover 3 is closed, the locking component 7 can be used to lock the arc-shaped cover 3 and the arc-shaped box 2 tightly, further enhancing the sealing of the device and preventing sewage from leaking from the gaps during the experiment.

[0036] In actual experimental operation, the experimenter can assemble different filter media into the arc-shaped box 2 in a specific order using multiple filter components 6 according to the preset purification target. After the device is assembled and confirmed to be sealed, the wastewater to be treated is injected into the arc-shaped box 2 through the inlet pipe 5. After entering the arc-shaped box 2, the wastewater will flow through each filter component 6 in sequence under the action of gravity. Through the adsorption, interception, and ion exchange of different filter media, impurities, odors, harmful ions and other pollutants in the water are gradually removed, and the purification effect is finally achieved. The purified water is discharged through the outlet pipe 4 at the bottom, completing the entire water purification experimental process.

[0037] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the filter assembly 6 includes a fixing ring 61, a cylinder 62, a ring 63, and a round cover 64; the cylinder 62 is movably mounted on the fixing ring 61, the ring 63 is rotatably mounted on the cylinder 62, and the round cover 64 is movably mounted on the ring 63.

[0038] The retaining ring 61, serving as the connection base between the filter assembly 6 and the arc-shaped box 2, is made of stainless steel. Its outer ring diameter precisely matches the preset installation position size inside the arc-shaped box 2, ensuring a stable and secure fit within the box and preventing displacement of the filter assembly 6 during the experiment. The bottom of the cylinder 62 rests stably on the retaining ring 61, and the adjacent retaining rings 61 seal against the cylinder 62 and the ring 63, preventing water leakage to the outside of the cylinder 62 during filtration. The cylinder 62, as the core cavity for containing the filter media, is made of transparent or semi-transparent high-strength acrylic or food-grade plastic, allowing researchers to easily observe the state of the internal filter media. When media needs to be added, the round cover 64 can be opened, and the media can be loaded into the cylinder 62. After filling, the round cover 64 can be closed.

[0039] like Figure 5 and Figure 6As shown, an annular groove 621 is provided between the outer and inner circumferential walls at the top of the cylinder 62, and a first thread 622 is provided on the outer side wall inside the annular groove 621. A plurality of circular through holes 623 are provided at the bottom of the cylinder 62.

[0040] The cylinder 62 has an annular groove 621 for placing and installing the ring 63, and a first thread 622 is provided to cooperate with the second thread 631 on the ring 63. The height of the cylinder 62 can be adjusted according to experimental requirements to fill different volumes of filter media.

[0041] like Figure 6 As shown, a second thread 631 is provided on the outer circumference of the ring 63. The ring 63 is located inside the annular groove 621, and the second thread 631 cooperates with the first thread 622.

[0042] When the height of the ring 63 needs to be adjusted, the experimenter only needs to hold the top of the ring 63 and rotate it clockwise or counterclockwise. At this time, the second thread 631 on the outer wall of the ring 63 will engage with the first thread 622 on the outer wall of the annular groove 621. When rotating clockwise, the second thread 631 moves downward along the first thread 622, and the ring 63 gradually sinks in the annular groove 621, thereby reducing the filling space of the filter medium in the cylinder 62. When rotating counterclockwise, the second thread 631 moves upward along the first thread 622, and the ring 63 gradually rises in the annular groove 621, expanding the filling space of the filter medium.

[0043] Once the ring 63 is adjusted to the target height, it can remain stably in its current position due to the static friction between the threads. It will not slide on its own due to the weight of the subsequent filter media or the impact of the sewage flow, thus ensuring the stability of the filter media filling space.

[0044] like Figure 6 As shown, the top of the round cover 64 is provided with a plurality of round holes 641, and the diameters of the plurality of round holes 641 and the plurality of round through holes 623 are the same.

[0045] It should be noted that since the same medium is filled inside the same filter component 6, in order to ensure that the internal medium does not leak, the diameters of the circular holes 641 and the circular through holes 623 on the same filter component 6 must be the same, so as to ensure that the internal medium does not leak and that the water flows smoothly.

[0046] like Figure 2 and Figure 7 As shown, an annular step 611 is provided on the inner side of the fixing ring 61, and the maximum diameter of the annular step 611 is equal to the outer diameter of the cylinder 62.

[0047] When the bottom of the cylinder 62 is placed on the annular step 611, the seamless fit between the maximum diameter of the annular step 611 and the outer diameter of the cylinder 62 prevents the cylinder 62 from swaying or shifting on the annular step 611. This ensures that the cylinder 62 remains vertical during the filtration process, preventing uneven distribution of the filter media due to tilting of the cylinder 62, which would affect the filtration efficiency. At the same time, the perfectly matched diameter also reduces the gap between the outer wall of the cylinder 62 and the annular step 611, reducing the risk of unfiltered wastewater leaking through the gaps and improving the overall sealing of the filter assembly 6.

[0048] like Figure 2 and Figure 3 As shown, the top of the arc-shaped box 2 is provided with a water inlet 21, and the water inlet 21 is connected to the water inlet pipe 5. The bottom of the arc-shaped box 2 is provided with a water outlet 22, and the water outlet 22 is connected to the water outlet pipe 4.

[0049] The inlet 21 is tightly connected to the inlet pipe 5; correspondingly, the outlet 22 is connected to the outlet pipe 4, guiding the sewage to flow naturally through the filter assembly 6 along the direction of gravity. The inlet 21 is located in the central area of ​​the top of the arc-shaped box 2, which allows the sewage to diffuse evenly in all directions after entering. The clean water purified by the multi-layer filter assembly 6 is completely collected at the bottom and then discharged through the outlet 22, avoiding residual water in the box.

[0050] like Figure 2 and Figure 3 As shown, the inner wall of the arc-shaped box 2 is provided with a plurality of first arc-shaped grooves 23 arranged linearly along the axis, and the inner wall of the arc-shaped cover 3 is provided with a plurality of second arc-shaped grooves 31 arranged linearly along the axis, and the first arc-shaped grooves 23 and the second arc-shaped grooves 31 cooperate with the fixing ring 61.

[0051] When the fixing ring 61 is placed in the first arc groove 23 of the arc box 2, the arc cover 3 is closed, and the second arc groove 31 will cause the fixing ring 61 to be inserted and limit the fixing ring 61, which will support the cylinder 62 on the fixing ring 61. At the same time, the fixing ring 61 can be flexibly adjusted to different positions to adapt to cylinders 62 of different heights.

[0052] Researchers can select filter components 6 of different heights according to changes in filtration requirements, thereby adjusting the number and layers of filter components 6 without requiring structural modifications to the arc-shaped box 2 or the arc-shaped cover 3. This greatly improves the convenience of the experiment.

[0053] like Figure 3As shown, the locking assembly 7 includes a first locking block 71, a second locking block 72, and locking rods 73; the first locking block 71 is fixedly installed on the outside of the arc-shaped box 2, and a plurality of locking holes 74 are respectively opened on the first locking block 71; the second locking block 72 is fixedly installed on the outside of the arc-shaped cover 3, and a plurality of locking rods 73 are rotatably installed on the second locking block 72, and the plurality of locking rods 73 cooperate with the plurality of locking holes 74.

[0054] In actual locking operation, after the arc-shaped cover 3 is closed, the experimenter only needs to rotate the locking rod 73 on the second locking block 72, aligning the locking rod 73 with the corresponding locking hole 74 on the first locking block 71. Then, rotating the locking rod 73 clockwise will cause the external thread at the end of the locking rod 73 to gradually engage with the internal thread on the inner wall of the locking hole 74. As the locking rod 73 is continuously screwed into the locking hole 74, the second locking block 72 will gradually move closer to the first locking block 71 under the force of the threads, thereby causing the arc-shaped cover 3 to fit tightly against the edge of the arc-shaped box 2. This effectively prevents sewage from leaking from the connection between the arc-shaped box 2 and the arc-shaped cover 3 during the filtration process.

[0055] The diameters of the circular holes 641 and circular through holes 623 on the various filter components 6 inside the arc-shaped box 2 are different.

[0056] It should be noted that, since the filter media filled inside each filter component 6 are different, the diameters of the round holes 641 and the round through holes 623 on different filter components 6 are different. This is to prevent the media inside the filter component 6 from falling out of the round holes 641 or the round through holes 623. At the same time, different filter media can be selected and combined in different orders, which greatly improves the convenience and selectivity of the experiment.

[0057] The working principle of this utility model is as follows: First, according to the experimental requirements, the round covers 64 on multiple filter components 6 are opened, and different filter media are placed inside the corresponding cylinders 62. At the same time, the ring 63 can be rotated according to the amount of media to be filled, and the position of the ring 63 inside the cylinder 62 is adjusted so that the ring 63 rises to the specified height. Then, the media is put into the cylinder 62, and finally the round cover 64 is installed on the ring 63.

[0058] Adjust the position of the fixing ring 61 inside the arc-shaped box 2 according to the height of the different filter components 6, so that the distance between adjacent upper and lower fixing rings 61 is equal to the height of the filter component 6. Place the entire filter component 6 on the annular step 611 on the fixing ring 61. After all the filter components 6 are placed, close the arc-shaped cover 3 and screw the locking rod 73 into the locking hole 74 with a professional tool to seal the arc-shaped cover 3 and the arc-shaped box 2. Then, introduce external sewage or rainwater through the water inlet pipe 5 at the top of the arc-shaped box 2. After filtration by multiple filter components 6, the water is discharged through the water outlet pipe 4 at the bottom of the arc-shaped box 2. After the experiment, open the arc-shaped cover 3 and remove each filter component 6 to pour out and recycle the internal medium.
