Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
The structural representation of the reverse osmosis water purifier first embodiment that Fig. 1 is proposed by this utility model.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
The structural representation of the reverse osmosis water purifier first embodiment proposed by this utility model shown in Figure 1.As it can be seen, the reverse osmosis water purifier that the present embodiment is proposed includes tertiary filter, preset filter group 1 as shown in Figure 1, reverse osmosis membrane filt 2 and active carbon filter 3.The most preset filter group 1 is arranged on reverse osmosis membrane filt 2 front end, and active carbon filter 3 is arranged on reverse osmosis membrane filt 2 rear end.The most preset filter group 1 includes PPF roughing efficiency air filter, UDF filter and the CTO filter being sequentially connected with.Preset filter group 1 can be removed chlorine residue in water, most suspended substances, rust, colloid and partial organic substances and smell and taste.Reverse osmosis membrane filt 2 can play the effect of sterilization, and active carbon filter 3 can further organics removal, smell and taste improve mouthfeel, thus prepare the pure water Gong drinking.
The outlet 22 of reverse osmosis membrane filt 2 is provided with a road water pipeline and a road dense water outlet pipeline.Being provided with Water quality detector 4 in water pipeline, Water quality detector 4 is arranged on the rear end of active carbon filter 3.Water quality detector 4 is preferably TDS and detects sensor.TDS is dissolvability solid amount in water, and units of measurement is mg/litre.The first function of TDS detection sensor is the quality of detection water purification；And simultaneously as in dense water dissolvability solid amount proportional with dissolvability solid amount in water purification, therefore, TDS detection sensor the second function be to detect the quality of dense water.Water quality detector 4 can also select other sensor device, does not limits at this.
Being provided with threeway 11 on dense water outlet pipeline, specifically, threeway 11 can be realized by tee T, threeway parts or other structure with said function or workpiece.Threeway 11 1 tunnel connection backflow branch road 6, a road connection reverse osmosis membrane filt 2, another road connection wastewater outlet 10 is also provided with scouring electromagnetic valve 9.The outlet of backflow branch road 6 connects the import 21 of reverse osmosis membrane filt 2, the dense water produced by reverse osmosis membrane filt 2 causes the import 21 of reverse osmosis membrane filt 2, thus realize again filtering, while preparing more standard compliant water purification, reverse osmosis membrane is rinsed, extends its service life.
The specific works process of reverse osmosis water purifier is: water purifier is started working, the entering water electromagnetic valve 5 of import 21 front end being arranged on reverse osmosis membrane filt 2 is opened, the tap water filtered through preset filter group 1 enters reverse osmosis membrane filt 2, and a part is discharged from water pipeline and passed through active carbon filter 3 and prepares water purification.TDS detection sensor is started working, the TDS value in on-line real-time measuremen water purification.The dense water outlet pipeline of reverse osmosis membrane filt 2 discharges dense water, scouring electromagnetic valve 9 is closed, concentrated stream enters to reflux branch road 6, flows through check valve 7 from the outlet 22 of reverse osmosis filter and waste water ratio 8 returns the import 21 of reverse osmosis filter, be again filtrated to get the water purification of a part.The waste water ratio 8 arranged on backflow branch road 6 can effectively reduce the pressure loss in reverse osmosis membrane, improves the water purification amount prepared further.When the detected value of TDS detection sensor is higher than setting value, it was demonstrated that now water quality is poor, can affect life-span of water quality reverse osmosis membrane impact if continuing cycling through backflow.Now, scouring electromagnetic valve 9 control circuit receives TDS detected value, and generation actuating signal is to scouring electromagnetic valve 9, and scouring electromagnetic valve 9 is opened, and is rinsed reverse osmosis membrane.
The reverse osmosis water purifier that the present embodiment is proposed is by arranging Water quality detector in water purification water side, realize water purification and dense water water quality that real-time online detection reverse osmosis membrane filt is discharged, and opening or closing scouring electromagnetic valve according to real-time water quality, it is ensured that reverse osmosis membrane itself will not be caused damage by the water quality rinsing reverse osmosis membrane.The feed water by reverse osmosis facility that the present embodiment is proposed have the advantage that cleaning water is good and reliability is high.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model each embodiment technical scheme.
