Abstract

The utility model discloses a reverse osmosis water filtering device. When a water outlet switch is turned on, pure water stored in a buffer member is used firstly, and the preliminary impurity water generated by a reverse osmosis filtering unit is conveyed to a wastewater conveying pipe by virtue of a branch pipe so as to be discharged; after certain time of water making, the pure water is directly conveyed to the water outlet switch by virtue of a pure water conveying pipe; in the process of conveying the pure water to the water outlet switch, the pure water is conveyed into the buffer member at the same time for supplement and buffer, so that good water making quality can be obtained without mounting a pressure water storage barrel and waiting for the pressure filtering time.

Description

Reverse osmosis water treatment plant

Technical field

The utility model is relevant with reverse osmosis water treatment plant, especially refers to a kind of reverse osmosis water treatment plant of making quality that promotes.

Background technology

General modal tap water uses after boiling tap water exactly, even if but through boiling or cannot effectively removing objectionable impurities contained in water (as heavy metal), be that tap water or other water sources are carried out to reverse osmosis processing so can drink at present the best mode of cleandrinking water, various objectionable impuritiess contained in processed water can be removed.

But with regard to general reverse osmosis treatment technology, total dissolved solids (the Total Dissolves Solids of the processed water in hydraulic pipe-line, hereinafter to be referred as TDS) after stopping water outlet, there will be the slow phenomenon that rises, in the time again opening gooseneck faucet, the TDS of processed water may exceed the TDS of former water within for some time at water outlet initial stage, therefore, after starting water outlet, often must also to wait for that the pressure filtration time of approximately 3 to 4 seconds can obtain the clean water of low TDS, tangible suitable inconvenience on water intaking is used.In order to solve this puzzlement, current modal treatment process is that pure water is first stored in a pressure water storage barrel, allow the initial stage water of high TDS be diluted by the stored pure water of pressure water storage barrel after feed pressure water butt, in the process so using in water intaking, just do not need to wait for the time of pressure filtration, but because pressure water storage barrel has volume to a certain degree, so installing and certainly will will consider that space configures the problem of bringing.

Embodiment

Refer to Fig. 1, reverse osmosis water treatment plant 10 of the present utility model includes a reverse osmosis filtering unit 20, an effluent switch 22, a water purification supply unit 30, a waste water transfer lime 60, a dividing cell 70, and a control unit 80.

Reverse osmosis filtering unit 20 is mainly by the various objectionable impuritiess (as heavy metal) that remove in former water, because reverse osmosis filtering unit 20 is known technology and non-emphasis of the present utility model, in order to save space, repeat no more its thin bilge construction in this appearance.

Effluent switch 22 is the water purification that produce for exporting reverse osmosis filtering unit 20.

Water purification supply unit 30 has a water purification transfer lime 31, a reverse checkvalve 32, a bolster 33, and a high-voltage switch gear 34.Water purification transfer lime 31 has a feed-water end 312 and connects reverse osmosis filtering unit 20 by feed-water end 312, and in addition, water purification transfer lime 31 also has the first water side 314 and one second water side 316 of a connection effluent switch 22; Reverse checkvalve 32 is installed on water purification transfer lime 31 and between reverse osmosis filtering unit 20 and effluent switch 22, can only makes uniflux in order to limit water purification; Bolster 33 is connected in the second water side 316 of water purification transfer lime 31, and supplementing of water purification can be provided on the one hand in making the water initial stage, can be used as on the other hand the buffering of water purification at course of conveying; High-voltage switch gear 34 is installed on water purification transfer lime 31 and between effluent switch 22 and reverse checkvalve 32, in order to the hydraulic pressure in sensing bolster 33.

It should be added that at this, the installation site of bolster 33 can be done to change according to actual needs, in detail, bolster 33 can be arranged between reverse checkvalve 32 and high-voltage switch gear 34, also can be arranged between effluent switch 22 and high-voltage switch gear 34, but in the present embodiment, the installation site of bolster 33 be allow effluent switch 22 between bolster 33 and high-voltage switch gear 34 for optimal selection.

One end of waste water transfer lime 60 connects reverse osmosis filtering unit 20, goes out in order to the discharge of wastewater that reverse osmosis filtering unit 20 is produced.

Dividing cell 70 has an isocon 71 and one point of manifold solenoid valve 72.Isocon 71 has a distributing inlet end 712 and and distributes water end (W.E.) 714, distributing inlet end 712 connects water purification transfer lime 31 and between reverse osmosis filtering unit 20 and reverse checkvalve 32, distribute water end (W.E.) 714 and connect waste water transfer lime 60, be delivered to waste water transfer lime 60 in order to the initial stage water impurity that reverse osmosis filtering unit 20 is produced; Divide manifold solenoid valve 72 to be installed on isocon 71, in order to control the uninterrupted of the initial stage water impurity in isocon 71.

Control unit 80 is electrically connected high-voltage switch gear 34 and a point manifold solenoid valve 72, in order to control respectively the keying of high-voltage switch gear 34 and the keying of point manifold solenoid valve 72.

In the time opening effluent switch 22, as shown in Figure 1, control unit 80 can start point manifold solenoid valve 72 and allow high-voltage switch gear 34 remain on closing condition, make reverse osmosis filtering unit 20 can turn to after entering water purification transfer lime 31 and flow in isocon 71 making the water impurity that the water initial stage produces (that is have high TDS water), then flow in waste water transfer lime 60 and discharge by isocon 71.On the other hand, because high-voltage switch gear 34 is not opened at this moment, so effluent switch 22 is from the interior stored water purification of bolster 33 making the water purification that the water initial stage discharges.

After reverse osmosis filtering unit 20 starts to make water for some time (approximately 3 to 4 seconds), as shown in Figure 2, control unit 80 can be closed point manifold solenoid valve 72 and be opened high-voltage switch gear 34 simultaneously, making the water purification that reverse osmosis filtering unit 20 produces (that is have low TDS water) be flowed directly to effluent switch 22 from water purification transfer lime 31 discharges, simultaneously also can some water purification in the process that is delivered to effluent switch 22 flow in bolster 33 and store, supplement on the one hand bolster 33 and make the water purification of using up making the water initial stage, on the other hand water purification is provided in course of conveying the use of buffering with adjusting, approach full-water level once bolster 33, high-voltage switch gear 34 just can be by sensed water level signal transmission to control unit 80, the motor (not shown) that control unit 80 is controlled in reverse osmosis filtering unit 20 shuts down and reaches the effect that allows reverse osmosis filtering unit stop making water.

In sum, shunting effect initial stage water impurity being provided by dividing cell 70 and bolster 33 supplement making the water purification that the water initial stage provides, make reverse osmosis water treatment plant 10 of the present utility model not need setting pressure water butt and reach and save the object of usage space, also do not need to wait for the time of pressure filtration and increase the convenience that water intaking is used making the water initial stage simultaneously.
