Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, with the Household water processor of the RO film device of automatic backwash, the work-ing life of improving the RO film.
The utility model solves the problems of the technologies described above the technical scheme that adopts:
A kind of Household water processor with automatic backwashing RO film device, comprise the RO film filter, magnetic valve, topping-up pump, waste water ratio, pipeline and controller, topping-up pump connects RO film filter water-in by magnetic valve, waste water ratio connects RO film filter wastewater outlet, it is characterized in that: described RO film filter, magnetic valve, topping-up pump, waste water ratio has two covers, an i.e. RO film filter, the first magnetic valve, the first topping-up pump, the first waste water ratio and the 2nd RO film filter, the second magnetic valve, the second topping-up pump, the second waste water ratio, the original water inlet end by threeway respectively with the first topping-up pump be connected topping-up pump and be connected, the pure water inlet of the one RO film filter and the 2nd RO film filter is connected to pure water inlet by threeway, the outlet of the first waste water ratio and the second waste water ratio is connected to wastewater outlet by threeway, and controller is controlled respectively the first magnetic valve, the second magnetic valve, the first topping-up pump and the second topping-up pump.
RO film in the described RO film filter also can replace with nanofiltration membrane.
Because the utility model has been taked above-mentioned technical measures, it compared with prior art has following advantage:
1, adopted two film filter system, realized the automatic mutual phase back flushing of two film filters, Effective Raise the work-ing life of film;
2, simple in structure, dependable performance.

Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the current direction synoptic diagram that state is made in the RO film filter water conservancy project processed of the utility model embodiment;
Fig. 3 is the current direction synoptic diagram of the RO membrane filter backwash state of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to figure l, the utility model comprises two its system of cover RO film filter, i.e. a RO film filter 5, the first magnetic valve 3, the first topping-up pump 2, the first waste water ratio 8 and the 2nd RO film filter 15, the second magnetic valve 17, the second topping-up pump 18, the second waste water ratios 11.The topping-up pump of every cover system connects RO film filter water-in by magnetic valve, and waste water ratio connects RO film filter wastewater outlet.For example, the first topping-up pump 2 connects a RO film filter water-in 4, the second topping-up pumps 18 by the first magnetic valve 3 and connects the 2nd RO film filter water-in 16 by the second magnetic valve 17.Former water or pre-process water source entrance end 1 by threeway 10 respectively with the first topping-up pump 2 be connected topping-up pump 18 and be connected, the pure water outlet 14 of a RO film filter 5 and the 2nd RO film filter 15 is connected to the pure water tap of pure water inlet 9 by threeway 10.The outlet of the first waste water ratio 8 and the second waste water ratio 11 is connected to the wastewater drainage pipe of wastewater outlet 12 by threeway 10.Controller is controlled respectively the first magnetic valve 3, the second magnetic valve 17, the first topping-up pump 2 and the second topping-up pump 18.
With reference to Fig. 2, during normal water processed, controller is opened the first magnetic valve 3 and the second magnetic valve 17, two RO film filter work, pre-process water flows out from the pure water water side of RO film filter by RO film 19 rear generation pure water, is pooled to the pure water tap of pure water inlet 9 by threeway 10, the RO film filter is processed the waste water of water generates and is discharged from the waste water mouth of RO film filter, is pooled to the wastewater drainage pipe of wastewater outlet 12 by threeway 10.
With reference to Fig. 3, when needs carry out back flushing to the RO film, controller controls the first magnetic valve 3 and cuts out, the pure water that the 2nd RO film filter 15 produces is then pressed to the pure water water outlet 7 of a RO film filter 5 by pipeline under the effect of the second topping-up pump 18, further press to again the RO film water purification face of a RO film filter 5, pressed again its RO film, press to the waste water face, discharge by a RO film filter waste water mouth 6, realize the back flushing of the RO film of a RO film filter 5; When controller controls the second magnetic valve 17 and cuts out, the pure water that the one RO film filter 5 produces is then pressed to the pure water water outlet 14 of the 2nd RO film filter 15 by pipeline under the effect of the first topping-up pump 2, further press to again the pure water surface of the RO film of the 2nd RO film filter 15, pressed again its RO film, press to the waste water face, discharge by the 2nd RO film filter waste water mouth 13, realize the back flushing of the RO film of the 2nd RO film filter 15.Like this, by controlling the working order conversion of two cover topping-up pumps and magnetic valve, make the mutual automatic backwash of film more than two or two.
