[0024] The stirring device includes a rotating shaft 7 rotatably connected to the tank body 1, a motor 8 mounted on the tank body 1, a first gear 9 driven by the motor 8, a second gear 10 and a third gear 11 coaxially mounted at both ends of the rotating shaft 7, three rotating rods 12 arranged in a ring array and rotatably connected to the partition plate 6, a fourth gear 13 coaxially mounted on the rotating rods 12, multiple sets of first stirring blades 14 linearly distributed on the rotating rods 12, and multiple second stirring blades 15 arranged in a ring on the rotating shaft 7; the first gear 9 and the second gear 10 are meshed together, and the third gear 11 and the three fourth gears 13 are meshed together.

[0025] The bottom of the tank 1 is an inclined surface. The scraper 16 has an inclined part and a vertical part. The inclined part and the inclined surface are slidably connected. Three scrapers 16 are provided on the second stirring blade 15. The scrapers 16 are slidably connected to the tank 1. Four mounting plates 17 are linearly arrayed on the scrapers 16. Multiple leakage holes 18 are provided on the mounting plates 17.

[0026] In this embodiment, after the raw water and oxygen are transported into the tank 1, the motor 8 is started to drive the first gear 9 to rotate. The first gear 9 and the second gear 10 mesh and drive each other. The second gear 10 then drives the shaft 7 and the third gear 11 to rotate. The third gear 11 meshes and drives three fourth gears 13 at the same time. The shaft 7 and the rod 12 then drive multiple sets of first stirring blades 14 and second stirring blades 15 to further stir and mix the raw water in the tank 1, increasing the oxygen content in the raw water and thus increasing the rate at which iron and manganese ions are oxidized into hydroxides or oxides. At the same time, the second stirring blades 15 also drive the scraper 16 and the mounting plate 17 to rotate during rotation. The scraper 16 can prevent hydroxides and oxides from adhering to the inner wall of the tank 1. Meanwhile, the mounting plate 17 increases the fluidity of the raw water during rotation, thereby improving the efficiency of stirring and mixing. In addition, the set leakage hole 18 will generate more turbulence when the water flows through, which helps to better disperse oxygen in the water and increase the contact area between oxygen and water, thereby improving the mixing effect and having good practicality.

The heating pipe 19 and the automatic exhaust valve 21 are used to control the solubility of oxygen to keep it stable and avoid affecting the mixing effect.
