[0035] Preferred embodiments of this utility model will be described in detail with reference to the accompanying drawings, which will facilitate the implementation of these embodiments by those skilled in the art. However, this utility model can be implemented in various different forms, and therefore is not limited to the embodiments described below. Furthermore, for clarity, components not connected to this utility model will be omitted from the drawings.

[0036] A high-density sedimentation tank for improving solid-liquid separation efficiency includes: sedimentation tank 1, fixed plate 2, motor 3, reducer 4, fixed base 5, drive gear 6, driven gear 7, stirring element, and scraper 9;

[0037] like Figure 1-2 As shown, the bottom of the sedimentation tank 1 is a conical structure, and the top is a columnar structure;

[0038] The two ends of the fixing plate 2 are fixed to the top of the sedimentation tank 1;

[0039] The motor 3 is mounted on the top of the fixed plate 2;

[0040] The reducer 4 is connected to the output end of the motor 3, and both ends of the reducer 4 are connected to the fixed plate 2 via the fixed rod 21;

[0041] like Figure 3-6 As shown, the two ends of the fixing base 5 are fixed to the top of the sedimentation tank 1, and an annular ring 51 is provided in the middle of the fixing base 5;

[0042] A ring of teeth is provided on the inner wall surface of the annular ring 51;

[0043] The drive gear 6 is located at the center of the annular ring 51, and the drive gear 6 is connected to the output end of the reducer 4.

[0044] There are three driven gears 7, which are evenly arranged around the driving gear 6, and the driven gears 7 respectively mesh with the teeth of the driving gear 6 and the ring 51.

[0045] The bottom of the drive gear 6 is connected to a first rotating rod 61;

[0046] like Figure 7-11 As shown, the stirring component includes: annular sleeve 81, support rod 82, vertical plate 83, and blade 84;

[0047] Each driven gear 7 has a second rotating rod 71 connected to its bottom;

[0048] Multiple stirring components are sleeved on both the first rotating rod 61 and the second rotating rod 71, and threaded holes are provided on both the first rotating rod 61 and the second rotating rod 71.

[0049] Multiple support rods 82 are evenly connected to the outer wall of the annular sleeve 81; multiple vertical plates 83 are fixed on each support rod 82; the annular sleeve 81 is provided with a through hole, and a screw passes through the through hole, so that the annular sleeve 81 is fixed together with the first rotating rod 61 and the second rotating rod 71.
