Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
The utility model provide firstly a kind of water cleaning systems, including be linked in sequence by pipeline 21 fore filter,
Entering water electromagnetic valve 6, booster pump 8, reverse osmosis filter 9 and post-filter, fore filter is through low tension switch 2 and tap water
Pipe is connected, and post-filter is connected with pure water tap, and sequential series have water processed between reverse osmosis filter 9 and post-filter
TDS detectors 10, water solenoid valve 11 and high-voltage switch gear 12, in the water outlet of the water inlet end and water TDS detectors 11 processed of booster pump 8
The bypass line of water backflow processed can be made by being parallel between end.
As shown in figure 1, paper folding filter core 3 and preposition carbon-point 4 are serially connected composition fore filter by pipeline 21, typically will
Paper folding filter core 3 is arranged on the water inlet end of preposition carbon-point 4, and the water inlet end of paper folding filter core 3 passes through low tension switch 2 and tap water interface 1
Connection, so as to be connected with running water water pipe, low tension switch 2 detects water feeding pressure, is controlled by entering water electromagnetic valve 6 and is connect with running water
The connection or closing of mouth 1, the water side of preposition carbon-point 4 is connected with booster pump 8 by entering water electromagnetic valve 6, gone out from fore filter
The water purification come is after increase pump 8, into reverse osmosis filter 9, by setting booster pump 8, can make from preposition carbon-point 4 out net
Water enters reverse osmosis filter 9 with steady pressure, avoids pure water caused by tap water inner pipe water pressure shakiness from going out water unstable, carries
The strainability of high reverse osmosis filter 9, meanwhile, the water purification into reverse osmosis filter 9 is also given with certain pressure, further
Improve the filter capacity of reverse osmosis filter 9.The composition of fore filter is also not limited to paper folding filter core 3 and preposition carbon-point 4,
It can be the filter core of any form or structure in the prior art, prefilter requirement can be met.
Water TDS detectors 10 processed are set in the water side of reverse osmosis filter 9, detected from 9 made water of reverse osmosis filter
TDS values, and control system is real-time transmitted to, compared with the preset value built in system, it is determined that whether water TDS processed surpasses in real time
Mark.To solve TDS excessive problems caused by water cleaning systems, when being again started up after especially shutting down every time, from reverse osmosis filter 9
Water TDS excessive problems processed out.Side is associated between the water inlet end of booster pump 8 and the water side of water TDS detectors 10 processed
Siphunculus road, bypass line are arranged between the water inlet end of booster pump 8 and the water side of water TDS detectors 10 processed, can be recirculation water
Enough pressure is provided to complete reflux course, meanwhile, the filtration, purification without re-starting whole flows can solve water processed
TDS excessive problems, so as to reduce power consumption, only one-way conduction in bypass line, conducting state is controlled by bypass solenoid valve 22,
In Water treatment, when the water TDS values processed detected in real time exceed systemic presupposition value, system control water solenoid valve 11 is closed,
Bypass solenoid valve 22 is opened, and entering water electromagnetic valve 6 is now still in open mode, the exceeded water processed come out from reverse osmosis filter 9
The water inlet end of booster pump 8 is back to through bypass line, after 8 voltage stabilizings of booster pump/supercharging, is reentered in reverse osmosis filter 9,
Reverse-osmosis treated again is carried out to exceeded water processed, is detected again through water TDS processed from the water processed of reverse osmosis filter 9 again out
Device 10 detects TDS values and compared with systemic presupposition value, such as still exceeded, continues to flow back, reciprocation cycle reverse-osmosis treated, until water processed
TDS values are less than systemic presupposition value, close bypass solenoid valve 22, open water solenoid valve 11, meet the water processed warp of TDS standards requirement
High-voltage switch gear 12 is entered in post-filter, and in the utility model, post-filter uses rearmounted carbon-point 13, through rearmounted carbon
