the upper side and the lower side of a rubber groove at the lower end of the right side of the filtering pipeline (10) are respectively provided with a threaded hole matched with a screw (37);
the method is characterized in that:
the device is started, the power shaft rotates to drive the gear to rotate, the gear rotates to drive the water inlet channel to rotate by being meshed with the gear ring, at the moment, sewage in the sewage tank is pumped out by the water suction pump and flows into the water inlet channel from the upper end of the water inlet channel, after the sewage enters the water inlet channel, the sewage and impurities in the sewage generate centrifugal force due to high-speed rotation of the water inlet channel, water is thrown into a cabin formed by the bent rod and the secondary filter screen from the centrifugal filter screen, large-particle impurities and the sewage which is not filtered by the centrifugal filter screen flow down along the inner walls of the water inlet channel and the filtering pipeline, pass through the through holes in the circular plate, flow into the lower side in the filtering pipeline, are filtered once again by the sedimentation filter screen and finally flow into the sewage tank, the water thrown into the bent rod can be secondarily filtered at the secondary filter screen and finally enters the water outlet channel, the filter screen of the secondary filter screen is finer than the centrifugal filter screen, and sewage and impurities which do not pass through the secondary filter screen can return to the interior of the water inlet channel and the filter pipeline through the lower side of the centrifugal filter screen and finally fall into the sewage tank;
when the water level continues to rise, can promote the ejector pad when walking inside the closed cabin and make the ejector pad drive the slider and move to the right, the pulling pendulum rod is rotatory, make the dog remove and mutual closure according to hexagonal groove orbit, plug up the mouth of falling into water of the inboard upper end of filter tube, the staff can stop the rotation of power shaft at this moment and dismantle and change the sediment filter screen to the screw after, the sewage that loses centrifugal force and can directly fall this moment will stay in dog upper end position because of the effect of dog, sewage can deposit through centrifugal filter screen's inclination and filter this moment, wait to deposit that the filter screen clearance is changed and finish resetting the device again and can continue sewage treatment, need not stop the water pump and also need not shift sewage, reached and changed the filter screen and need not suspend filterable purpose.
