In the process of flowing upward, sedimentation is performed again, and finally the water is discharged from the drain pipe 11. Through diversion and re-sedimentation, the sedimentation and filtration efficiency and effect of the vertical flow sedimentator are improved.

[0032] See also Figure 1 , 4 -6, the first spacer ring 41 and the second spacer ring 42 are truncated cone-shaped structures that are small at the top and large at the bottom, so as to facilitate the downward flow of water.

[0033] See also Figure 1 A second sewage outlet 14 is provided on the outer wall of the outer barrel body 10. The second sewage outlet 14 is located on the upper side of the first spacer ring 41 and close to the first spacer ring 41. A first valve 15 is installed on the second sewage outlet 14 to facilitate the discharge of sediment on the upper side of the first spacer ring 41.

[0034] Furthermore, the inner wall of the outer barrel 10 is provided with a second retaining ring 18, and the outer circumference of the first spacer ring 41 abuts against the second retaining ring 18, so as to facilitate the installation and positioning of the flow dividing device 40. Specifically, the second retaining ring 18 is bonded to the inner wall of the outer barrel 10.

[0035] See also Figure 1 , 5 The inner hole of the first spacer ring 41 is provided with a connecting sleeve 47, which extends upward, and the lower end of the central tube 20 is inserted into the connecting sleeve 47, so that the central tube 20 is connected to the diverter device 40. When cleaning, the central tube 20 can also be conveniently taken out.

[0036] See also Figure 1 A conical bucket 16 is provided at the bottom of the outer barrel 10. The conical bucket 16 has two functions: one is to increase the space at the bottom of the diverter 40 to reduce the impact of the water flow on the sediment; the other is to facilitate the collection and discharge of the sediment.

In this embodiment, the outer barrel body 10, the central tube 20, the overflow weir 30 and the diverter 40 are all made of PVC.

[0039] The action process or principle of the utility model is as follows:

[0040] See also Figure 1 , water enters the central tube 20 from the water inlet pipe 21. Due to the tangential connection between the water inlet pipe and the central tube, the water flows downward along the central tube 20 in a rotation. When passing through the diverter 40, due to the centrifugal force, the impurities are closer to the inner wall of the central tube 20, so that the water with more impurities enters the sedimentation channel 46, and the water with less impurities flows out from the lower end of the extension tube 44, flows upward through the guide tube 45, and enters the area between the outer barrel 10 and the central tube 20. Since the lower end of the baffle 43 exceeds the length of the extension tube 44, it has little effect on the water flowing out of the sedimentation channel 46, which facilitates the sedimentation of impurities in the conical bucket 16. As for the water flowing upward through the guide tube 45, since the guide tube 45 plays a role in stabilizing the flow, the water entering the area between the outer barrel 10 and the central tube 20 will not rotate, but will rise steadily, which is conducive to re-sedimentation. Thus, the sedimentation filtration efficiency and effect of the vertical flow sedimentator are improved through diversion and re-sedimentation.
