The steps of using a hydraulically driven and self-cleaning backwash water filter herein will be described in detail with reference to fig. 1 to 6: initially, the baffle 24 is in an upright position, the connecting chamber 19 is in a flow-through position, the waste discharge chamber 42 is in a blocked position, and the clean water valve 36 is in a blocked position.
When the sewage water purifier works, sewage water flows down from the sewage water inlet 23, large particles in the sewage water can be filtered when the sewage water passes through the filter plate 21, the sewage water after primary filtration flows into the secondary filter chamber 14 from the connecting chamber 19, the sewage water flows out into the storage chamber 12 after secondary filtration through the filter screen 13 on the outer side because the sewage water discharge chamber 42 is in a closed state, at the moment, the floating plate 43 floats on the water surface and slowly rises along with the collection of the sewage water, when the sewage water in the storage chamber 12 reaches a certain degree, the floating plate 43 touches the wide piston 25 and pushes the wide piston to move upwards, so that the narrow oil pipe 27 moves upwards, the T-shaped rod 28 is driven to move upwards, the clean water valve 36 is driven to move upwards, then the sewage water is discharged from the clean water discharge port 44, and when the T-shaped rod 28 moves upwards, the horizontal inclined block 40 connected with the T-shaped rod 28 through the rope moves to the right due to the existence of tensile force, when a large amount of sewage after secondary filtration in the storage cavity 12 flows out, the floating plate 43 will move down again to the original position, and the vertical inclined block 39 will move down due to the pressure of the floating plate 43, so that the horizontal inclined block 40 moves to the left, then the T-shaped rod 28 moves down, then the clean water valve 36 moves down to block the clean water outlet 44, and when the T-shaped rod 28 moves, the vertical rack 30 will be driven to move, so that the first gear 31 rotates, then the first rotating shaft 32 rotates, so that the ratchet 45 rotates, but due to the characteristics of the ratchet 45, only when the T-shaped rod 28 moves down, the ratchet 45 can rotate, so that the second gear 33 engaged with the ratchet rotates, so that the second rotating shaft 34 rotates, then the rotating pin 52 rotates, the rotating pin 52 contacts with the inclined block 47 during rotation to move outward, and when the inclined block 47 is no longer located in the groove of the annular column 51, the ring-shaped column 51 will rotate a quarter turn rapidly due to the restoring force of the spring between the fixed pin 50 and the rotating pin 52, at this time, the groove of the ring-shaped column 51 will accommodate the sloping block 47 at the next position, in preparation for the next rotation of the ring-shaped column 51, after the ring-shaped column 51 rotates a quarter turn, the third rotating shaft 53 will rotate a quarter turn, so that the baffle 24 will rotate a quarter turn, at this time, the connecting cavity 19 will be blocked, the sewage will not flow into the secondary filtering cavity 14 through the connecting cavity 19, and during the rotation of the baffle 24, the baffle 24 will press the sliding block 17 to the left side, then the sewage will flow out to the storage cavity 12 from the gap where the sliding block 17 is located, at this time, the third rotating shaft 53 rotates to drive the fourth rotating shaft 54 to rotate, then drive the third gear 55 to rotate, so that the horizontal rack 56 moves to the right, so that the sewage discharge cavity 42 is in the circulation, however, at this time, because the clean water outlet 44 is in a blocked state, water will begin to accumulate in the storage chamber 12 again, and as the liquid level in the storage chamber 12 rises, sewage will flow from the storage chamber 12 to the secondary filter chamber 14, and will wash away impurities adhered to the inner wall of the secondary filter chamber 14, and then flow out from the sewage outlet chamber 42, so as to achieve the purpose of back flushing, because the sewage outlet speed of the sewage outlet chamber 42 is less than the accumulation speed of the sewage flowing into the storage chamber 12, the liquid level in the storage chamber 12 will rise continuously, so as to drive the floating plate 43 to rise, when the floating plate 43 rises to contact the wide piston 25 and drive the wide piston 25 to rise, the clean water valve 36 will move up to open the clean water outlet 44, so as to flow out the sewage in the storage chamber 12, however, the reset spring 46 will drive the second inclined block 59 to rise, and then push the first inclined block 58 to move left, so as to move the horizontal rack 56 left, even if the sewage drain chamber 42 is returned to the clogged state again, the baffle 24 is then reversed by a quarter turn to put the connection chamber 19 in the circulation state, and the filtering of the sewage is performed again.
The invention has the beneficial effects that: the invention achieves the aim of backwashing by controlling the opening and closing of the valve, judges whether the backwashing is needed or not by the internal and external pressure difference of the traditional circuit control system, realizes the backwashing by hydraulic driving and the lifting of the floating plate, does not need a complex control circuit, can operate the device only by sewage flow, has simple structure, is convenient to maintain, does not need monitoring and fully automatically performs the backwashing operation.
In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
