[0030] A filter assembly for filtering raw water is provided at the bottom of the top plate 4;

[0031] The bottom of the fixed circular plate 18 is fixedly connected to the second annular plate 12, the inside of the second annular plate 12 is fixedly connected to the first circular plate 13, the bottom of the first circular plate 13 is fixedly connected to the second circular plate 14, the bottom of the second circular plate 14 is fixedly connected to the annular plate 16, and the bottom of the annular plate 16 is fixedly connected to the bottom inner wall of the cylindrical reinforced concrete structure 1;

[0032] A mixing assembly for mixing raw water is disposed inside the second annular plate 12 .

[0033] In the utility model, the filtering assembly includes an annular screen 3 fixedly connected to the bottom of the top plate 4, a mounting seat 2 is provided at the bottom of the annular screen 3, and an annular mounting cavity 10 used in conjunction with the annular screen 3 is provided at the top of the mounting seat 2, which can complete the installation of the annular screen 3 and facilitate the replacement of the annular screen 3.

[0034] In particular, the filter assembly also includes a first annular plate 7 arranged inside the mounting seat 2, an annular groove 9 is provided on the outer wall of the first annular plate 7, two symmetrically arranged notches 8 are provided on the top of the first annular plate 7, the notches 8 are connected to the annular groove 9, and two symmetrically arranged protrusions 11 are fixedly connected to the inner wall of the mounting seat 2. The notches 8 and the annular grooves 9 are used in conjunction with the protrusions 11 to complete the installation and disassembly of the annular screen 3 and quickly discharge internal impurities.

[0035] In particular, the mixing assembly includes a plurality of arc-shaped baffles 20 fixedly connected to the bottom of the fixed circular plate 18, gaps exist between the plurality of arc-shaped baffles 20, and the plurality of arc-shaped baffles 20 are arranged in a ring shape, so that the original water can be divided into multiple streams.

[0036] In particular, the mixing assembly also includes a connecting column 21 fixedly connected to the middle position of the bottom of the fixed circular plate 18, a conical block 24 is fixedly connected to the bottom of the connecting column 21, a second conical through hole 23 is opened inside the second circular plate 14, a first conical through hole 22 is opened inside the first circular plate 13, the connecting column 21 is located inside the first conical through hole 22, and the conical block 24 is located inside the second conical through hole 23, which can reduce the space inside the first conical through hole 22 and the second conical through hole 23 and improve the raw water collision effect.

[0037] In particular, a plurality of arc-shaped holes 17 are opened on the outer wall of the fixed circular plate 18, and a plurality of hemispherical plates 25 are fixedly connected to the inner wall of the second annular plate 12. The plurality of hemispherical plates 25 are arranged in a ring shape, and the interiors of the plurality of hemispherical plates 25 correspond to the gaps between the plurality of arc-shaped baffles 20, so that the raw water can be divided into multiple streams before being discharged, thereby improving the collision effect.

[0038] In particular, a rectangular hole 15 is opened on one side of the annular plate 16. The rectangular hole 15 is arranged on the side of the annular plate 16 away from the water inlet pipe 6, so that the raw water can be separated and then reunited to achieve preliminary collision mixing.

[0039] In particular, two symmetrically arranged handles 5 are fixedly connected to the bottom of the first annular plate 7 to facilitate the subsequent removal of internal impurities.

[0040] Working principle: When PAM mixing is required, polyacrylamide is added into the device, and raw water is sent into the cylindrical reinforced concrete structure 1 through the water inlet pipe 6. At this time, the raw water is divided into two streams, entering from both sides of the annular plate 16, and finally entering the inside of the annular plate 16 through the rectangular hole 15 to achieve preliminary collision mixing;

[0041] The raw water merges into one stream and continues to rise. After passing through the conical surface of the conical block 24, it separates again and rises along the second truncated cone through hole 23. After entering the first truncated cone through hole 22, since the first truncated cone through hole 22 is inclined, multiple streams of raw water collide again and are discharged through the top of the first truncated cone through hole 22.

[0042] After being blocked by the fixed circular plate 18, the raw water moves to the top of the first circular plate 13. At this time, the raw water can only pass through the gaps between the multiple arc-shaped baffles 20 and be discharged in multiple streams. Since the arc-shaped holes 17 and the gaps between the multiple arc-shaped baffles 20 are staggered, the raw water divided into multiple streams contacts the hemispherical plate 25 and is separated again, and finally discharged through the arc-shaped holes 17. After multiple separations and combinations, the slow mixer can be directly replaced.

[0043] At this time, the impurities can be directly discharged after being filtered by the annular screen 3, and the impurities remain inside the annular screen 3. When the internal impurities need to be processed, the first annular plate 7 can be rotated by the handle 5. At this time, the protrusion 11 moves inside the annular groove 9. When the protrusion 11 is aligned with the notch 8, the first annular plate 7 and the mounting seat 2 can be detached, thereby quickly discharging the internal impurities, which is convenient to use.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
