Mark by reference to the accompanying drawings the following drawings mark:
The 1-topping-up pump, 11-water inlet pipe, 12-the first pipe connecting, 2-rough filtering device, 23-the second pipe connecting, 3-T-valve, 34-the 3rd pipe connecting, 36-outlet conduit, 4-fine filtering device, 45-the 4th pipe connecting, 46-the 5th pipe connecting, 5-waste water ratio.
Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.
Water filtering device of the present utility model comprises topping-up pump 1, rough filtering device 2, T-valve 3 and fine filtering device 4 as shown in Figure 1.One end of topping-up pump 1 is connected with the water source by water inlet pipe 11, and the other end is connected with the water-in of rough filtering device 2 by the first pipe connecting 12.Rough filtering device 2 consists of (also can adopt according to actual needs other corresponding filtering membrane) by ultra-filtration membrane or microfiltration membrane, and the water outlet of rough filtering device 2 is connected with the water-in of T-valve 3 by the second pipe connecting 23.The first water outlet of T-valve 3 is connected with fine filtering device 4 water-ins by the 3rd pipe connecting 34, and the second water outlet of T-valve 3 forms the by-pass channel of water outlet by the filtered water of outlet conduit 36 outputs.Fine filtering device 4 consists of (also can adopt according to actual needs other corresponding filtering membrane) by reverse osmosis membrane or nanofiltration membrane, and the water outlet of fine filtering device 4 is connected with rising pipe 36 by the 5th pipe connecting 46, can mix with the water in the aforementioned by-pass channel.
After topping-up pump 1 enters rough filtering device 2 with former hydraulic pressure, water after the coarse filtration enters T-valve 3, the water quality condition of T-valve 3 after according to former quality and coarse filtration distributes the water yield ratio that enters rising pipe 36 and fine filtering device 4, reduce the water yield that enters fine filtering device satisfying under the prerequisite of effluent index as far as possible, when fine filtering device adopts reverse osmosis membrane, the flooding quantity of fine filtering device can not be lower than 10 milliliters, in order to avoid reverse osmosis membrane damages because of dehydration.
Further as shown in Figure 1, fine filtering device 4 also is provided with dense water out, and dense water out connects waste water ratio 5 by the 4th pipe connecting 45, and waste water ratio 5 is used for the output of control fine filtering device waste water.
Better when raw water quality, and can reach water quality requirement after filtering through rough filtering device the time, but that regulating three-way valve is arranged to the flooding quantity of fine filtering device is minimum, thereby improves filtration efficiency; When raw water quality relatively poor (for example larger water quality of heavy metal contamination), but regulating three-way valve is closed the first water outlet of T-valve fully, thereby realizes fully essence filter.
