After mixing in the case 5 and thoughtlessly accomplishing in advance, rotate covering 8 and make it be in vertical state, keep rotating motor 7's operation this moment, mix the liquid in the case 5 and flow out from the liquid outlet under rocking, fall into in the coagulation basin 2. After the liquid in the mixing tank 5 is completely dispensed, the covering member 8 is rotated to be in a horizontal state, and preparation is made for the next wave of premixing. After the coagulating sedimentation treatment is completed, water flows into the post-treatment tank 3 for other treatments.
When the liquid level of the coagulation tank 2 is high, the extendable agitating plate 81 may be extended from the auxiliary tank. Then the covering part 8 is rotated left and right, and the telescopic stirring plate 81 extends into the liquid in the coagulation tank 2 for stirring and stirring.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
