Background technology
Water purification, drinking water function unite two into one by water-purifying machine, meet the multiple demand of family or office space drinking-water, it is the major transformation of water way, the principle of work of the water purification machine on existing market is that water is sent into filtration equipment for clarifying by topping-up pump, water after purification is stored in clear water tanks again, reinject and heat or refrigeration system, drink for user.
Usual filtration equipment for clarifying adopts the assemblies such as PP cotton, gac, ultra-filtration membrane, nanofiltration membrane, reverse osmosis membrane, RO reverse osmosis membrane is a kind of semi-permeable membranes, when liquid by semi-permeable membranes time, a part through, and another part is trapped, the part be trapped is commonly called dense water.In existing technology, this part dense water can directly be discharged, and causes very large waste, and in fact, the dense water that RO reverse osmosis membrane produces not is not worth, a large amount of experimental studies shows, dense water is recycled, and still can ensure water quality, and reduce water consumption greatly.Can prevent filter core from blocking to the cleaning of filter core in water-purifying machine, and can take away the impurity in filter assemblies, at present, in water-purifying machine, filter-core back-flushing is washed structure and is adopted multiple magnetic valve to be realized by time variable control, easily causes leaking in pipeline because magnetic valve quantity is more.
Utility model content
Technical problem to be solved in the utility model is the automatic back-flushing device providing a kind of water-saving reverse osmosis water purifier, can realize the cleaning to purification filtering assembly, effectively prevents the blocking of filter assemblies.
The technical scheme that the utility model solves the problem is as follows:
An automatic back-flushing device for water-saving reverse osmosis water purifier, is characterized in that:
It comprises prefilter assembly, water tank, RO reverse osmosis membrane and ozone-sterilizing device, and described water tank inside is separated into former hydroecium, dense hydroecium and pure water rooms successively by dividing plate and baffle plate,
In described pure water rooms, aeration plate is set, be connected by airway between described ozone-sterilizing device and aeration plate, described former hydroecium is connected with prefilter assembly by pipeline, the dense water out of described RO reverse osmosis membrane is connected by pipeline with dense hydroecium, the pure water inlet of RO reverse osmosis membrane is connected with pure water rooms by pipeline
The described water outlet of former hydroecium and the water outlet of pure water rooms are connected respectively by the feed-water end of pipeline with purification filtering assembly, described dense hydroecium water outlet is connected with the water side of purification filtering assembly, the water side of described purification filtering assembly is connected with water pump by pipeline, the water side of described water pump is divided into two-way, one tunnel is connected with the feed-water end of RO reverse osmosis membrane, and another road is installed concentrated water drainage and gone out valve.
As further improvement, spillway is left in the dividing plate upper end between described former hydroecium and dense hydroecium.
Described former hydroecium water outlet, dense hydroecium water outlet and pure water rooms water outlet are provided with line check valve.Can prevent former hydroecium, dense hydroecium, pure water rooms to flow backwards when system works is run pollution like this.
Principle of work of the present utility model is, tap water enters former hydroecium by prefilter assembly, then flow out after purification filtering component filters from the water outlet of former hydroecium, flow into water pump and then flow into RO reverse osmosis membrane, the water outlet of RO reverse osmosis membrane is divided into pure water inlet and dense water out, corresponding inflow pure water rooms and dense hydroecium, along with the dense water in dense hydroecium gets more and more, dense water flows into the circular treatment of former hydroecium realization to dense water by spillway.Described when after system cloud gray model for some time, native system can run backwashing procedures automatically, be used for rinsing purification filtering assembly and RO reverse osmosis membrane by water in pure water rooms by water pump, the concentrated water spout from RO reverse osmosis membrane is escaped and enter dense hydroecium by backwashing water, reaches the requirement of rinse-system.
Compared with prior art, the beneficial effects of the utility model are:
1, automatic back-flushing device structure of the present utility model is simple, the effective flushing to purification filtering assembly can be realized, effectively prevent the blocking of purification filtering assembly, extend the work-ing life of purification filtering assembly, and can situation of leaking be avoided, the water cycle processed can also be shortened by the pressure of water pump.
2, the water tank that water purifying chamber, former hydroecium, dense hydroecium are three-in-one is adopted, its Central Plains hydroecium is connected with dense hydroecium, there is the dividing plate of one piece of certain altitude centre, reach this height after the dense water of RO reverse osmosis membrane enters dense hydroecium etc., former hydroecium can be overflowed into, after mixing with former water, reenter purification filtering system through topping-up pump again, to reach dense Water reuse, play the effect of water saving, greatly save wastewater discharge.
