[0031] The working principle is to load the coagulant and flocculant in the first dosing box 2 and the second dosing box 3, and then open the electric control valve 5 (the electric control valve 5 is a solenoid valve, and a suspended particle turbidity sensor is added at the outlet of the flotation tank to detect whether the outlet water is clear. If the outlet water is not clear, the suspended particle turbidity sensor transmits a feedback signal to the processor, and the processor controls the electric control valve 5 to adjust the opening to increase; if the outlet water is clear, the suspended particle turbidity sensor transmits a feedback signal to the processor, and the processor controls the electric control valve 5 to adjust the opening to maintain. Since the above-mentioned control method is an automated PID control method for adding drugs in conventional water treatment, since it is a conventional technical means, the adjustment details will not be described in detail here), and then the coagulant and flocculant can be automatically added without long-term manual access. When in use, the annular sealing block 612 on the cover plate 611 is fixed to the top of the mixing cylinder 63, and the threaded connecting rod 616 is connected to the threaded connecting rod 616.

At this time, the limit rod 610 can be inserted into the rectangular insertion hole 619. At this time, the threaded clamping rod 66 is inserted into the threaded clamping hole 67, and the nut 68 is rotated at the same time so that the nut 68 and the threaded clamping rod 66 are fixed. At this time, the driving motor 62 is started so that the cylindrical body 64 can drive the first connecting rod 65 and the second connecting rod 617 to rotate, and then drive the rotating rod 613 and the stirring rod 614 to rotate. At this time, the electric control valve 5 is started so that the medicine liquid flows out from the first medicine adding box 2 and the second medicine adding box 3, and then can flow to the flotation tanks on both sides in the diverter tube 71. When one side needs to be blocked, the piston 72 is inserted into the diverter tube 71, and the rectangular clamping block 76 is inserted into the rectangular clamping frame 74, and then the positioning rod 75 is inserted into the positioning hole 77 to complete the fixation.
