RO water purifier structure with purified rinse water RO film filter, comprise raw water inlet, be connected with pretreatment filters on raw water inlet, the end of pretreatment filters connects entering water electromagnetic valve, and entering water electromagnetic valve is connected with booster water pump, booster water pump is connected with the RO film filter water-in of RO film filter assembly, the pure water outlet of RO film filter assembly is connected with the second reverse checkvalve, the second reverse checkvalve is connected with rearmounted carbon filter with pressure pot respectively, rearmounted carbon filter is connected with the pure water tap, the condensed water outlet of RO film filter assembly is communicated with water drain by waste water ratio, be communicated with the branch road with magnetic valve between the RO film filter water-in of booster water pump and RO film filter assembly and between the second reverse checkvalve and rearmounted carbon filter.
Branch road with magnetic valve is provided with the first reverse checkvalve.
Described pretreatment filters is three groups.
Described pretreatment filters is that PP is cotton, gac or ultra-filtration membrane at least one.
The beneficial effects of the utility model: simple in structure; easy to connect; practical; simple to operate, automatic operation, purified the environment of RO film; the RO water purifier work structuring mode of condensed water immersion RO film under stopped status is converted under stopped status and goes out the condensed water in the RO film with pure water; soak the mode of RO film with purified rinse water, improve RO film scale formation under stopped status, greatly extended the work-ing life of RO film.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment 1;
The structural representation that Fig. 2 is the utility model embodiment 2.
Embodiment
As shown in Figure 1, RO water purifier structure with purified rinse water RO film filter, comprise raw water inlet 1, be connected with pretreatment filters 2 (3 on raw water inlet 1, 4), pretreatment filters 2 (3, 4) end connects entering water electromagnetic valve 5, and entering water electromagnetic valve 5 is connected with booster water pump 6, booster water pump 6 is connected with the RO film filter water-in 9 of RO film filter assembly 10, the pure water outlet 11 of RO film filter assembly 10 is connected with the second reverse checkvalve 14, the second reverse checkvalve 14 is connected with rearmounted carbon filter 16 with pressure pot 15 respectively, rearmounted carbon filter 16 is connected with pure water tap 17, the condensed water outlet 12 of RO film filter assembly 10 is communicated with water drain 18 by waste water ratio 13, be communicated with the branch road with magnetic valve 8 between the RO film filter water-in 9 of booster water pump 6 and RO film filter assembly 10 and between the second reverse checkvalve 14 and rearmounted carbon filter 16, described pretreatment filters is preferably three groups.Described pretreatment filters 2 (3,4) is that PP is cotton, gac or ultra-filtration membrane at least one.
As shown in Figure 2, other parts as shown in Figure 1, are to be provided with the first reverse checkvalve 7 on the branch road with magnetic valve 8 with Fig. 1 difference.
Former water (routine is municipal tap water, also can is other water sources) enters filtering system by raw water inlet 1, through passing through successively pretreatment filters 2, pretreatment filters 3, pretreatment filters 4, by entering the RO film filter water-in 9 of RO film filter assembly 10 after entering water electromagnetic valve 5, booster water pump 6; Pure water exports 11, stores for drinking by entering in pressure pot 15 the second reverse checkvalve 14 from RO film filter assembly pure water; Open pure water tap 17, the pure water be stored in pressure pot 15 flows out for drinking after rearmounted carbon filter 16.
Pure water in pressure pot 15 completely after system-down, now entering water electromagnetic valve 5 is closed, magnetic valve 8 cuts out after opening for some time, the pure water in pressure pot 15 enter in RO film filter assembly 10 by magnetic valve 8, the first reverse checkvalve 7, RO film filter water-in 9; Flow to water drain 18 from condensed water outlet 12 outflows, flushing waste water than 13 after extruding the interior condensed water of RO film filter 10, flushing RO film; Magnetic valve 8 cuts out.Make like this RO film under stopped status under clean environment, the RO film is effectively protected, extend RO film work-ing life.The utility model effectively prevents the RO film failure condition that fouling is stopped up under stopped status.
In Fig. 2, the first reverse checkvalve 7 is to prevent that the water after topping-up pump from entering in pure water pipe in the pressure pot 15 that enters the storage pure water by magnetic valve 8.
While after the pure water of water purifying plant production is filled water butt, stopping water processed; magnetic valve 8 is opened; now the pure water in water butt enters RO film filter assembly water-in 9, the former water of high density in RO film filter assembly is flow to water drain 18 from condensed water outlet 12 outflows, flushing waste water than 13 by magnetic valve 8, the first reverse checkvalve 7; consume so a small amount of purified rinse water RO film; make the RO film under stopped status under the pure water guard mode, can extend greatly the work-ing life of RO film.
If magnetic valve 8 adopts electrical ball valve, the stopping valve that can two-wayly cut out, the first reverse checkvalve 7 can save.
