[0018] The first direct flow section 1, the mixed flow section 2 and the second direct flow section 3 can all be conventional pipes, which can be metal pipes or plastic pipes. The first direct flow section 1, the mixed flow section 2 and the second direct flow section 3 are coaxially arranged, and the wastewater flows along the first direct flow section 1, the mixed flow section 2 and the second direct flow section 3 in sequence. The dosing port 4 is used to add a medicine to the wastewater. When in use, the dosing port 4 can be connected to a dosing mechanism, such as a dosing valve.

[0019] The inner holes of the first direct flow section 1, the mixed flow section 2 and the second direct flow section 3 are flow channels for the wastewater. The inner diameter of the mixed flow section 2 is larger than the inner diameters of the first direct flow section 1 and the second direct flow section 3. When the wastewater enters the mixed flow section 2 from the first direct flow section 1, the flow channel becomes larger and the flow rate of the wastewater decreases. Therefore, disturbances will occur at the connection between the first direct flow section 1 and the mixed flow section 2, causing the wastewater to collide and mix with each other, so that the reagents can enter the wastewater more evenly.

[0020] The two ends of the mixing section 2 are detachably connected to the first direct current section 1 and the second direct current section 3 respectively. When the interior of the mixing section 2 is blocked by impurities such as sludge, or when the mixing mechanism is damaged, the mixing section 2 can be removed, the interior can be dredged or the mixing mechanism can be inspected and replaced, and then the mixing section 2 can be installed between the first direct current section 1 and the second direct current section 3. Later maintenance is convenient without the need to remove the entire pipeline mixer.

[0021] Specifically, the two ends of the mixed flow section 2 can be connected to the first direct current section 1 and the second direct current section 3 through the flange 12. The ends of the mixed flow section 2, the first direct current section 1 and the second direct current section 3 are all welded with flanges 12, and the flange 12 on the mixed flow section 2 is connected to the flanges 12 on the first direct current section 1 and the second direct current section 3 through a plurality of bolts. In order to improve the sealing of the connection and prevent water leakage, a sealing gasket is provided between the flange 12 of the mixed flow section 2 and the flanges 12 of the first direct current section 1 and the second direct current section 3, and the sealing gasket can adopt a commonly used sealing material such as an annular rubber gasket.

[0022] The mixing mechanism is used to promote the full mixing of the reagent into the wastewater. The mixing mechanism of this embodiment includes a mounting frame 13, a rotating shaft 14 and a fan blade 15. The mounting frame 13 is mounted on the inner wall of the mixing section 2, the rotating shaft 14 is rotatably mounted on the mounting frame 13, and the fan blade 15 is fixedly mounted on the rotating shaft 14. The mounting frame 13 can be mounted on the inner wall of the mixing section 2 by screws, etc. Specifically, the mounting frame 13 includes an inner cylinder and an outer cylinder, and the inner cylinder and the outer cylinder are fixedly connected by a plurality of radial connecting rods. The rotating shaft 14 is mounted on the inner cylinder, and an annular positioning boss can be provided on the inner wall of the mixing section 2. The outer cylinder is mounted on the positioning boss by a plurality of screws.

[0023] When the wastewater flows through the fan blades 15, the fan blades 15 are pushed to rotate, and the fan blades 15 stir the wastewater, thereby promoting full mixing of the reagent and the wastewater.

The first diverter holes 8 can be 4, 6, etc. When the wastewater reaches the first diverter hole 8, it will flow along the first diverter hole 8 to the first mixing hole 7. When the wastewater is discharged from the first diverter hole 8, the direction of the water flow is inclined toward the center of the first mixing hole 7. Therefore, the wastewater discharged from each first diverter hole 8 will mix and collide in the first mixing hole 7, thereby promoting the full mixing of the reagent in the wastewater with the wastewater.
