Operation principle and workflow:
Rainwater enters rainwater rainwater to be filtered district by rainwater water inlet, enters clear water zone by liquid-level difference principle through defecator, and impurity is delayed at filter cloth and water district to be filtered.When impurity is too much, filter cloth is blocked, and rainwater throughput reduces, and district to be filtered water level rises, ball float to floating, pulls frame bar, frame bar to pass through pull rope with water level, walking around fixed pulley, pulling valve door-plate, district to be filtered rainwater enters sewage buffer area by sewage draining exit and flows out.Owing to water district to be filtered water level declines suddenly, water in clear water zone reversely flows into buffer area to be filtered, below filtering holes that filter cloth is recoiled, filter cloth bag impurity attachment surface is by turning on one's side laterally in filter bag, the impurity that will be attached on filter cloth flows out sewage draining exit entrance blowdown buffer area through outlet of sewer discharge with water.
In backwash process, owing to produce big backwash power, it is necessary to strengthen sectional area and the counter-flushing liquid potential difference of sewage draining exit, cause the valve plates needing large volume of ball float just can open sewage draining exit, overall volume will be increased and increase cost.In order to solve the problems referred to above, frame plate arranges pressure balance film apparatus, when district's SEA LEVEL VARIATION to be filtered, hydraulic pressure suffered by pressure balance film apparatus and valve plates device is relative constant, pressure balance film apparatus is by pressure lever one end, make the other end give valve plates lifting force, for reducing the liquid-level pressure suffered by valve plates, make valve plates easily to open.
Being described in detail specific embodiment of the utility model above, but it is only used as example, this utility model is not restricted to particular embodiments described above.To those skilled in the art, any equivalent modifications carrying out this practicality and replacement are the most all among category of the present utility model.Therefore, the impartial conversion made under without departing from spirit and scope of the present utility model and amendment, all should contain in the range of this utility model.
