Embodiment
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 1, according to water cleaning systems of the present invention, comprise pretreatment unit 10, discharging device, and the first water purification branch road to be connected respectively with the water side of pretreatment unit 10 and the second water purification branch road, the water side of the first water purification branch road is communicated with discharging device respectively with the water side of the second water purification branch road, first water purification branch road has been arranged in series on carbon-point filter core or uf processing unit 20, second water purification branch road and has been arranged in series reverse-osmosis treated unit 30.According to water cleaning systems of the present invention, two independent water purification branch roads are split up into after pretreatment unit, first water purification branch road is purified pretreated former water further by carbon-point filter core or uf processing unit 20, and from discharging device water outlet, is purified the domestic water that grade is relatively low.Second water purification branch road is purified pretreated former water further by reverse-osmosis treated unit 30, and from discharging device water outlet, is purified grade relatively high, the pure water that can directly drink.Also namely water cleaning systems of the present invention passes through first, second water purification branch road independence water purification, clean level different two kinds can be provided to purify waste water, and compared to existing technology, because the second water purification branch road is no longer by carbon-point filter core or uf processing unit 20, effectively can reduce the treatment capacity of carbon-point filter core or uf processing unit 20, extend its working hour, thus improve the life-span of whole water cleaning systems.
Preferably, according to the difference of raw water quality, carbon-point filter core or uf processing unit 20 can be chosen as carbon-point filter core or ultra-filtration element, and particularly, if raw water quality contents of residual chlorine is high, carbon-point filter core or uf processing unit 20 can use carbon-point filter core; If raw water quality colloidal content is high, carbon-point filter core or uf processing unit 20 can use ultra-filtration element; This system can select filter core flexibly according to water quality, has universality, extends lifetime of system.
Shown in composition graphs 1, pretreatment unit 10 comprises the cotton filter core 11 of the PP connected successively and active carbon filter core 12, the cotton filter core 11 of PP is connected with former water interface, first a various granule foreign in former water is filtered, active carbon filter core 12 is connected to the water side of the cotton filter core 11 of PP, there is the effect of filtering with purification, effectively can remove the impurity such as the organism in water.
As shown in Figure 1, water cleaning systems also comprises the first-class gauge 40 be arranged in series on the first water purification branch road, and add up the water yield of the first water purification branch road (i.e. domestic water branch road), the life-span for each water purification unit of the first water purification branch road reminds.Usually, first-class gauge 40 is arranged on the downstream of carbon-point filter core or uf processing unit 20, and traffic statistics are more accurate.
As shown in Figure 1, the second water purification branch road has also been arranged in series entering water electromagnetic valve 50, second gauge 60 and stabilized pressure pump 70 successively, entering water electromagnetic valve 50, second gauge 60 and stabilized pressure pump 70 are arranged between pretreatment unit 10 and reverse-osmosis treated unit 30.Not during water processed, entering water electromagnetic valve 50 is in normally off, opens during water processed, and the effect of second gauge 60 is pure water branch road current total amounts, reminds for each water purification cell life.
Composition graphs 1 illustrates the principle of work of reverse-osmosis treated unit 30, and the water that stabilized pressure pump 70 exports enters reverse-osmosis treated unit 30, and in pipeline, the effect of reverse checkvalve 33 is the aqueous refluxs prevented in pipeline.Reverse-osmosis treated unit 30 also has waste water ratio electromagnetic valve 31 and scouring electromagnetic valve 32, and waste water ratio electromagnetic valve 31 controls discharge of wastewater ratio, and scouring electromagnetic valve 32 is in normally off, is in opened condition when performing flushes instructions.
Preferably, water cleaning systems also comprises and is arranged in series at the second water purification branch road and is positioned at the post-processing unit 80 in reverse-osmosis treated unit 30 downstream, and is arranged on the water cell 90 between post-processing unit 80 and reverse-osmosis treated unit 30.Namely the product water of reverse-osmosis treated unit 30 supplies user through post-processing unit 80, or stores through water cell 90, then flows through post-processing unit 80 and supply user.
Post-processing unit 80 generally adopts composite filter element, composite filter element mainly comprises carbon-point filter core and ultra-filtration membrane filtrate, store the product water after for some time in the product water of further process reverse-osmosis treated unit 30 and water tank 91, finally reach and remove the effect such as bacterium, peculiar smell.
Water cell 90 comprises the water tank 91 and pressure-detecting device 92 that can bear certain pressure, pressure-detecting device 92 mainly detects the water pressures on this water route, and control the entering water electromagnetic valve 50 of preprocessing part, when this branch road hydraulic pressure declines, entering water electromagnetic valve 50 is opened, stabilized pressure pump 70 operates, system water.When this branch road hydraulic pressure raises, entering water electromagnetic valve 50 is closed, and stabilized pressure pump 70 shuts down, and system stops water processed.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
According to water cleaning systems of the present invention, owing to being split up into two independent water purification branch roads after pretreatment unit, compared to existing technology, second water purification branch road is no longer through carbon-point filter core or uf processing unit, thus effectively reduce the treatment capacity of carbon-point filter core or uf processing unit, extend its working hour, thus improve the life-span of whole water cleaning systems.
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.
