3. A purifying method of an apparatus for purifying pure water, which is adapted to an apparatus for purifying pure water as claimed in claim 1, the purifying method of an apparatus for purifying pure water comprising the steps of:
s1: firstly, a centrifugal cylinder (02) is driven to rotate on a mounting frame (01) through a driving mechanism, then, the preliminarily filtered water is conveyed between filter cavities (19) through a shunt pipe (06) until the filter cavities (19) are full, the water pressure is kept constant, the water in the filter cavities (19) can continuously permeate reversely through a permeable membrane (17) and then flow into a water collecting tank (18), and finally, the water flows out through a water purifying hole (15);
s2: after long-time use, the inside of the centrifugal cylinder (02) needs to be cleaned, at the moment, a bolt between the upper cover (03) and the centrifugal cylinder (02) is loosened, the bolt between the mounting frame (01) and the upper cover (03) is fixed, so that the rotation of the centrifugal cylinder (02) can not drive the upper cover (03) to rotate, the dirt scraping cover (24) can not rotate along with the centrifugal cylinder (02), the pressure resistant ring (20) can also continuously rotate along with the rotation of the centrifugal cylinder (02), at the moment, the dirt scraping cover (24) can not move, so that the rotating roller (21) can continuously rotate on the surface of the pressure resistant ring (20), and the inner wall of the dirt scraping cover (24) away from the rotating roller (21) can continuously scratch one side of the pressure resistant ring (20) close to the collecting cavity (14), so that impurities centrifugally arranged on the pressure resistant ring (20) can not scratch into the collecting cavity (14);
s3: because the pressure-resistant ring (20) rotates all the time, every time the pressure-resistant ring (20) drives the push plate (25) to rotate to the position of the rotary roller (21), the rotary roller (21) and the dirt scraping cover (24) can push the push plate (25) to move into the slot (16), so that the baffle plate (27) moves towards the sliding cavity (28), the baffle plate (27) can not block the gate (07) any more, and water stains formed by a large amount of impurities in the collecting cavity (14) can flow into the dirt discharging cavity (22) through the gate (07), and directly flow out through an opening below the dirt discharging cavity (22).
