10. A method of using the high efficiency flow directing device for flocculation according to any one of claims 1 to 9, characterized in that: The specific steps of the method for using the high-efficiency flow guide device for flocculation are as follows: S1: First, the flocculant is added to the inside of the dosing ring (3) through the dosing pipe (301), and then the flocculant will flow through the through hole (302) to the inside of the first flow guide cylinder (1), and then the water pump (6) and the frequency conversion motor (4) are started; S2: The water pump (6) will draw raw water into the inside of the first flow guide cylinder (1) through the water inlet flange (601) and the water inlet pipe (602) during operation, and the baffle (7) provided at the water outlet of the water inlet pipe (602) will split the raw water during use, so that it enters the inside of the first flow guide cylinder (1) through the periphery of the baffle (7); S3: The frequency conversion motor (4) drives the paddle (402) to rotate rapidly through the rotating shaft (401) during operation, and the paddle (402) can fully stir the raw water and flocculant in the first flow guide cylinder (1) during rotation, and the paddle (402) can also lift the treated water during rotation, so that the water in the first flow guide cylinder (1) flows upward, and the first backflow pipe (103) is provided, which makes the flocculated water in the first flow guide cylinder (1) flow back into the first flow guide cylinder (1) during use, which is beneficial to improve the flocculation effect and form better alum flowers, which is beneficial to subsequent precipitation and improves the water quality; S4: With the work of the paddle (402), part of the treated water will flow into the second flow guide cylinder (2), which can strengthen the flocculation reaction and improve the flocculation effect during operation, and the filter plate (205) provided in the second flow guide cylinder (2) can improve the water quality of the outlet water; S5: The rotating shaft (401) can also drive the rotating block (5) to rotate during rotation, and the rotating block (5) will drive the scraper (502) to rotate through the rotating plate (501) during rotation. When the scraper (502) rotates, it will scrape off the solid impurities on the lower surface of the bottom filter plate (205), thereby improving the water outlet effect of the device.
