Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 1, the invention provides a kind of water-purifying machine system, include pretreatment unit 10, intermediate treatment unit 20 and post-processing unit 30, wherein pretreatment unit 10, intermediate treatment unit 20 and post-processing unit 30 are connected successively; Pretreatment unit 10 includes the cotton filtration unit 11 of pp and active carbon filtering device 12, the cotton filtration unit 11 of pp is mainly used in the macrobead things such as silt in preliminary Filtered tap water and iron rust, and active carbon filtering device 12 is mainly used in adsorbing the peculiar smell in tap water; Tap water after pretreatment unit 10 filters tentatively can improve the water quality of tap water, prevent the impurity in tap water or particulate matter from impacting damage to the film in middle processing unit 20 or post-processing unit 30 filtration unit, improve the work-ing life of film further.For meeting the demand of people to different quality, intermediate treatment unit 20 includes first flow path parallel with one another and the second stream; Wherein first flow path is preferably provided with reverse osmosis unit 23, and for effectively to improve cleaning water, reverse osmosis unit 23 is provided with stabilized pressure pump 21, because reverse osmosis membrane filtration precision is higher above, fenestra is less, resistance is comparatively large, therefore needs stabilized pressure pump 21 to provide system working pressure; Second stream is provided with nanofiltration device 22, and be preferably ultralow pressure nanofiltration device, ultralow pressure nanofiltration device does not need can meet system works demand according to the hydraulic pressure of tap water self when stabilized pressure pump; It should be noted that ultralow pressure nanofiltration device normally works under the hydraulic pressure of tap water self, it can retain the small organic molecule that in water quality, monovalent metallic ion and a small amount of divalent-metal ion and relative molecular mass are less than 200, can retain ion such as sodium ion, potassium ion etc. useful to human body in water quality so to greatest extent; Based on such scheme, for meeting user's demand higher to water quality, mixing device 26 is provided with between intermediate treatment unit 20 and post-processing unit 30, mixing device 26 fully can mix the water quality after the purification of first flow path and the second stream, it is made at utmost to retain the material of human body requirements, and remove objectionable impurities to greatest extent, improve the hygienic quality of tap water, reduction user drinks water risk; Preferably, mixing device 26 can regulate the throughput ratio of first flow path and the second stream, to realize the ratio of adjustable first flow path and the mixing of the second stream water quality, thus improves the quality of mixing water quality.
Further, for the ease of the control between stream different in water cleaning systems, first flow path is also provided with the first magnetic valve 25, after preferably reverse osmosis unit 23 is located at by the first magnetic valve 25; After second stream being also provided with the second magnetic valve 24. preferably nanofiltration device 22 being located at by the second magnetic valve 24; The water processed in water cleaning systems between different stream effectively can be controlled by the setting of above-mentioned magnetic valve, water quality after facilitating user only need take nanofiltration device purification or the water quality after only needing reverse osmosis unit to purify, at utmost improve the hommization demand of water cleaning systems.
Further, post-processing unit 30 can be composite filtering equipment, and composite filtering equipment elects granulated active carbon and ultra-filtration membrane combination as; Such design effectively can ensure that the water quality after reverse osmosis membrane or nanofiltration membrane does not have peculiar smell.
Further, as shown in Figure 2, for ensureing that water cleaning systems fully, timely can provide water purification, pressure pot 40 can be provided with between mixing tank 26 and post-processing unit 31; For storing the mixed water quality of mixing tank 26, for user provides water purification for subsequent use.
According to above technical scheme, introduce working process and the principle of water-purifying machine system of the present invention below further:
As shown in Figure 1 and Figure 2, when tap water enters pretreatment unit 10, successively after pp face filtration unit 11 and active carbon filtering device 12 filter, enter intermediate treatment unit 20; Enter intermediate treatment 20 and can be divided into first flow path and the second stream; First flow path purifies through reverse osmosis unit 23 after being pressurizeed by stabilized pressure pump 21 again, and the second stream directly purifies through nanofiltration device 22; Can enter after water quality after intermediate treatment unit 20 purifies is mixed by mixing tank 26 in pressure pot 40 again and store or directly can flow to discharging device after processing unit 30 purifies; For improving the suitability of this water cleaning systems further, when user only needs pure water (water namely after reverse osmosis unit purification) time, the second magnetic valve 24 on the second stream can be closed; When user only needs nanofiltration water (water namely after nanofiltration device purification), the first magnetic valve 25 in first flow path can be closed; And when first flow path or the second stream work independently, mixing tank 26 quits work, System Operation power consumption can be saved like this, reduce use cost; When user needs mixing water (i.e. the water of mixing after reverse osmosis unit and nanofiltration device purification), on first flow path first magnetic valve 25 and the second stream, the second magnetic valve 24 is in normally open simultaneously, and mixing tank 26 normally works simultaneously.
According to such scheme, the present invention also provides a kind of water-purifying machine, mainly comprises above-mentioned water cleaning systems or the control method of water cleaning systems.
Apply above technical scheme, the present invention brings following technique effect:
By adopting above technical scheme, water cleaning systems provided by the invention, providing for user multiple-quality water demand simultaneously, at utmost can ensure material useful to human body in water quality, and removing objectionable impurities to greatest extent; And after mixing further, reach the best demand of human body water, improve drinking water safety.
Separately, by adopting above technical scheme, the invention provides the control method of water cleaning systems, adopting the easiest method, effective steering logic can be reached, for user provides control method that is the most convenient, reliable, low cost.
To sum up, water-purifying machine provided by the invention, can meet the demand of user for drinking water safety, health, low cost.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
