[0020] In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0021] like Figure 1-Figure 3 As shown, the flocculation continuous sand filter consists of a frame 1, a discharge valve 2, a cleaning box 3, a cleaning blade 4, a rotating shaft 5, a sealing cover 6, a rotating shaft 7, a feed cylinder 8, a quicksand cylinder 9, a bearing 10, a coupling 11, a frequency conversion motor 12, a support 13, a fixing frame 14, and a stirring motor 15.

[0022] A cleaning box 3 is provided on the frame 1, and the cleaning box 3 is connected to the flocculation component. The flocculation component is supported by a support frame on the side. A fixing frame 14 is provided on the side of the cleaning box 3, and the fixing frame 14 is used to support the cleaning component. The cleaning component partially extends into the cleaning box 3;

[0023] The cleaning assembly includes a stirring motor 15, a rotating shaft 5 and a cleaning blade 4. One end of the rotating shaft 5 extends into the cleaning box 3 and rotates with the inner wall on one side. The other end is transmission-connected to the stirring motor 15 fixedly mounted on the fixing frame 14. The cleaning blade 4 is sleeved on the rotating shaft 5.

[0024] Three sets of cleaning components are provided, and the three sets of cleaning components are provided with different heights.

[0031] How it works

[0032] The sewage to be purified and the flocculant are poured into the quicksand barrel 9. Filter sand is set in the quicksand barrel 9. The frequency conversion motor 12 drives the rotating shaft 7 to rotate and pushes the filter sand mixed with the sewage toward the cleaning box 3. After the filter sand falls into the cleaning box 3, the stirring motor 15 rotates to drive the cleaning blades 4 to break up the filter sand for a second time, so that it contacts the sewage again to improve the overall flocculation effect. Three groups of cleaning components are set inside the cleaning box 3, and they have a certain height difference. During stirring, the height difference setting facilitates the continuous falling of the filter sand. Multiple stirrings ensure the flocculation quality. Finally, the purified water is discharged through the discharge valve 2 to complete the collection. When the amount of filter sand in the quicksand barrel 9 is insufficient, the sealing cover 6 is opened, and the frequency conversion motor 12 drives the rotating shaft 7 to reverse, and the filter sand is brought into the quicksand barrel 9 to complete the filling.
