Description
Technical field
The utility model relates to purified water device, belongs to water purifying device technical field.
Background technology
The protection of current national to environment is increasing, wherein also more and more higher to the requirement of water, water quality condition is also more and more subject to the concern of more conglomerate, wherein pure water is applied to all trades and professions, as pharmacy, chemical industry, electronics, beverage and community central water supply etc., therefore reverse osmosis water purifier obtains the application of increasing industry; Wherein the emptying problem of the strainer in use procedure is not considered in the manufacture of most of pure water equipment, and when making filtration, operating pressure is excessive, causes raw water pump initial designs pressure excessive, does not reach power conservation requirement; Production cost strengthens, and wastes energy.Therefore design the emptying of strainer, to the operating pressure reducing raw water pump, have very important meaning to enterprise and society.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of and has that structure is simple, cost is low, can the reverse osmosis purified water device of available protecting raw water pump.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of reverse osmosis purified water device, comprise the water inlet pipe by pipeline sequential communication, raw water box, filtration unit, first-stage reverse osmosis device, intermediate water tank, secondary high-pressure pump adds cleaning system, second level reverse osmosis apparatus and pure water tank, it is characterized in that, also comprise a cleaning system and accurate filter, the feed-water end of described accurate filter is communicated with cleaning system, the water side of described accurate filter then adds cleaning system with secondary high-pressure pump respectively, suction culvert between filtration unit and first-stage reverse osmosis device is communicated with, and described filtration unit is also provided with emptying pipe, described emptying pipe is also provided with by-pass valve control, described by-pass valve control is communicated with Controlling System.
Further, the water outlet of described second level reverse osmosis apparatus is also provided with the defective water return line be communicated with described raw water box.
And the water outlet of described first-stage reverse osmosis system is also provided with defective water water port.
In addition, described filtration unit comprises the mechanical filter and activated charcoal filter that are linked in sequence.And be also sequentially set with washing unit, chemicals dosing plant and cartridge filter between described filtration unit and first-stage reverse osmosis system.
The beneficial effects of the utility model are: the utility model structure is simple, practical, use cost is low, be convenient to maintenance, and effectively improve pure water efficiency, by arranging emptying pipe on filtration unit, decrease the original pressure to the raw water pump between raw water box and filtration unit, extend the work-ing life of raw water pump.

Embodiment
Be that the utility model is described in detail below in conjunction with specific embodiment.
Fig. 1 is the one-piece construction schematic diagram of the utility model one embodiment; Fig. 2 is the schema of the utility model one embodiment.
As depicted in figs. 1 and 2: reverse osmosis purified water device, comprise the water inlet pipe by pipeline sequential communication, raw water box 1, filtering system 2, first-stage reverse osmosis device 4, intermediate water tank 5, secondary high-pressure pump adds cleaning system, second level reverse osmosis apparatus 6 and pure water tank 7, also comprise cleaning system 3 and an accurate filter, the feed-water end of described accurate filter is communicated with cleaning system 3, the water side of described accurate filter then adds cleaning system with secondary high-pressure pump respectively, suction culvert between filtering system 2 and first-stage reverse osmosis device 4 is communicated with, and described filtering system 2 is also provided with emptying pipe, described emptying pipe is also provided with by-pass valve control, described by-pass valve control is communicated with Controlling System, opening and closing automatically of by-pass valve control on the emptying pipe of automatic controlled filter system 2, and then control the automatic operation of whole system, lack of water is protected automatically, make system interlink.
In addition, the water outlet of described second level reverse osmosis apparatus 6 is also provided with the defective water return line be communicated with described raw water box 1, for underproof water is back to raw water box 1.And the water outlet of described first-stage reverse osmosis device 4 is also provided with defective water water port, for the discharge of defective water.
In the present embodiment, described filtering system 2 comprises the mechanical filter and activated charcoal filter that are linked in sequence.And be also provided with the washing unit, chemicals dosing plant and the cartridge filter that are linked in sequence between described filtering system 2 and first-stage reverse osmosis device 4, for filtration and the cleaning of water.
Working process of the present utility model is: former water enters raw water box 1 by water inlet pipe, water in raw water box 1 enters mechanical filter and activated charcoal filter by raw water pump, i.e. filtering system 2, then through washing unit, chemicals dosing plant and cartridge filter, enter first-stage reverse osmosis device 4, the qualified water produced enters intermediate water tank 5, defective water discharges through defective water water port, qualified water enters second level reverse osmosis apparatus 6 by secondary high-pressure pump again, the qualified water that second level reverse osmosis apparatus 6 is produced enters pure water tank 7, defective water is back to raw water box 1 by defective water return line.
The above is only the preferred implementation of the utility model patent; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model patent principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection domain of the utility model patent.
