The course of work of the utility model:
When work, the filtering foreign that circulating water flow carries recirculated water through steel wire rack, sundries is trapped in steel wire rack, a timing
Between after, intercepted sundries is more and more, will result in secondary filter inlet and outlet and generates certain pressure difference, circulating water flow also can
It reduces.When pressure difference inside and outside strainer arrives greatly preset value, it is necessary to carry out blowdown operation to secondary filter.
Blowdown funnel is designed as cavity format, constitutes a semi-enclosed cavity with steel wire rack.Blowdown funnel is connected with pipe axis, with
The sewage pipe that pipe axis is connected is equipped with blowdown valve after stretching out water inlet pipe, and blowdown valve is connected to circulating water outlet pipe.Recirculated water into
Water (pressure P1) and water outlet (pressure P2) between there are certain pressure difference (△ P=P1-P2)。
The utility model provides a kind of mechanical waterpower economic benefits and social benefits backwash secondary filter, realizes and cleans to the economic benefits and social benefits of strainer.The
One kind cleans strainer using negative pressure backwash principle.When blowdown valve is opened, in the work of recirculated water inlet outlet pressure differential △ P
Under, recirculated water can flow into blowdown funnel on the outside of steel wire rack, simultaneously because blowdown funnel end is with steel wire rack contact site, there are openings, follow
Ring water can also flow into blowdown funnel on the inside of the steel wire rack, after through pipe axis and sewage pipe flow into circulating water outlet pipe, while will be in steel wire rack
The sundries in portion washes away.
To still having the impurity remained on strainer after the backwash cleaning of strainer negative pressure, the utility model provides second of cleaning
