The stirring mechanism 2 is provided with stirring rods 21 corresponding to the primary tank 11 and the secondary tank 12, respectively.
The stirring mechanism 2 comprises a main support plate 22 which is horizontally arranged, and a central shaft 5 is fixedly arranged at the center of the main support plate 22;
a group of stirring assemblies are symmetrically arranged at two ends of the main support plate 22 respectively, and each stirring assembly comprises two stirring rods 21 respectively arranged in the primary tank 11 and the secondary tank 12 and a roller group 23 positioned on the main support plate 22;
the stirring rod 21 and the roller group 23 are driven by the main motor 6.
Each roller group 23 comprises three rollers distributed in an isosceles triangle, and comprises a driving wheel positioned at the top and two driven wheels positioned at the bottom, wherein the driving wheel is clung to the wheel surfaces of the two driven wheels at the bottom, and the two driven wheels are clung to the upper surface of the edge of the primary tank 11;
a conical fluted disc is arranged on the body of the stirring rod 21 of each stirring mechanism 2, and the main motor 6 drives the stirring rod 21 in the primary pool 11 and the driving wheel in the roller group 23 through a differential 24 respectively;
the power input end of the differential 24 is linked with the motor shaft of the main motor 6, and the two power output ends of the differential 24 are linked with the driving wheel and the stirring rod 21 respectively; one of the power output ends is coaxial with the wheel shaft of the driving wheel, and the other power output end is meshed with a bevel gear disc on the rod body of the stirring rod 21 through a bevel gear.
The stirring rod 21 in the secondary pool 12 is driven by another set of main motors 6 and a differential 24, and two power output ends of the differential 24 are linked with the bevel gear disc of the stirring rod 21 in the secondary pool 12 at one end and linked with the bevel gear disc of the stirring rod 21 in the primary pool 11 at the other end.

The bottom of the sedimentation tank 13 is in a cone bucket shape, and the end with the smaller cone bucket area is the bottom end.
Annular baffle 131 is provided with to the inside wall middle part level of sedimentation tank 13, baffle 132 in the baffle is close to the vertical setting in one side at sedimentation tank 13 center, and interior baffle 132 is the annular equally, and a plurality of breachs have all been seted up on the lateral wall of sedimentation tank 13 and the upper portion of interior baffle 132, and breach circumference array distributes.
When the invention is used, under the condition that the whole tank body is emptied, the valves between the tank bodies are closed and blocked, and then the wastewater and the coagulant to be treated are put into the primary tank 11. The main motor 6 is started, under the action of the main motor 6, the differential 24 drives the driving wheels in the roller group 23 to rotate, and under the friction of the driving wheels, the two driven wheels positioned at the bottom synchronously rotate, so that the roller group 23 drives the stirring mechanism to rotate by taking the middle shaft 5 as a shaft. And in this process, the puddler 21 that is arranged in primary pond 11 starts, because be helical blade on its body of rod, consequently play the effect of the water of turning over in the vertical direction, and puddler 21 in primary pond 11 is the water of turning over from top to bottom, and ordinary stirring leaf of non-drives the water motion in the horizontal direction, because rabbling mechanism 2 is whole just horizontal rotation promptly, so this kind of stirring mode is the first motion route for the annular route on a slow scale, and in this motion process, vertical turning over is the second motion route. After the coagulant and the water in the primary tank 11 are mixed uniformly, a valve between the primary tank 11 and the secondary tank 12 is opened, because a part of flocculation is generated in the primary tank 11 at this time, the stirring rod 21 plays a role of assisting in squeezing the flocculation in the primary tank 11 into the secondary tank 12 under the effect of communication between the lower parts of the primary and secondary tanks through the action of the stirring rod 21. And the main motor 6 corresponding to the stirring rod 21 in the secondary pool 12 is linked with the stirring rod 21 in the primary pool 11 through another differential 24, because it is required to ensure that the force applied to the stirring rod 21 in the primary pool 11 by the output of the two differentials 24 is the same as that for driving the stirring rod 21, the rotation directions of the stirring rods 21 in the primary pool 11 and the secondary pool 12 are opposite, namely, the stirring rod 21 in the secondary pool 12 is moved from bottom to top in the turning action on the water body. This movement pattern helps to carry the flocs out of the primary tank 11. And because of the downward-upward turning, the upper water body can easily enter the space between the side wall and the inner baffle 132 in the sedimentation tank 13, and the upper water body is basically purified water. In the secondary tank 12, the flocculation is relatively heavy, so that the flocculation can be carried upwards by turning over the stirring rod 21, thereby being beneficial to leading the coagulant to have better flocculation effect. And finally, opening a valve between the sedimentation tank 13 and the secondary tank 12, and allowing the water body in the secondary tank 12 to enter the sedimentation tank for sedimentation. Because the liquid level in the original tank body can be reduced after the valve is opened, only the waste water to be purified and the coagulant need to be added, and the water purification effect is not influenced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
