Description

Reverse osmosis water purifier

The utility model relates to a kind of water-purifying machine for preparing pure water, particularly relates to a kind of reverse osmosis water purifier.

Along with the raising of people's living standard and the quickening of rhythm of life, and because factors such as worry water pollution, existing increasing people begins purified drinking water.The applicant is 97240602.6 on August 25th, 1997 to the application number that Patent Office of the People's Republic of China proposes, the utility application that name is called " reverse osmosis water purification machine " is exactly a kind of equipment of making purified drinking water, it has the electricity consumption of need not, installation, use and advantage such as easy to maintenance, but finds that in use also there is following deficiency in it:

1, the pure water aquifer yield is not of uniform size under the situation that user's tap water hydraulic differs, the ratio of desalinization instability, and when hydraulic pressure is on the low side, might not water outlet.

2, adopt manual mode flushing reverse osmosis membrane, flush time and flushing are artificially controlled break time, have forgotten flushing sometimes, can't guarantee flushing and rinsing quality to reverse osmosis membrane.

3, adopt the manual mode shutdown, water tank water completely back very important person goes to turn off the tap, otherwise pure water overflows automatically from overflow port, causes water waste.

4, water tank does not have sterilising plant, has the easy secondary pollution of water of water tank.

This practical purpose is to provide a kind of reverse osmosis water purifier, has aquifer yield and ratio of desalinization and stablizes, exists the water of water tank not to be subject to secondary pollution, can save advantage such as water source.

Aforesaid the utility model reverse osmosis water purifier is owing to be provided with electromagnetic pump before reverse osmosis membrane, can improve the intake pressure of water-purifying machine reverse osmosis membrane, reverse osmosis membrane can be worked under desired pressure, make certain aquifer yield of water-purifying machine maintenance and stable ratio of desalinization; Owing to be provided with entering water electromagnetic valve and scouring electromagnetic valve, realize automatic water inlet, system water, washed completely back auto stop of reverse osmosis membrane and water tank water automatically, auto stop in the time of also can realizing the pipeline lack of water, and with the working condition of pilot lamp indication machine; Owing to added ozonizer, can produce ozone at regular time and quantity and squeeze in the water of water tank, make it to reach the purpose of sterilization fresh.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is one of the utility model reverse osmosis water purifier structural representation (omitting the aft section structure);

Fig. 2 is two (omitting the previous section structure) of the utility model reverse osmosis water purifier structural representation;

Fig. 3 is each parts annexation floor map of the utility model reverse osmosis water purifier.

Fig. 1, Fig. 2 and Fig. 3 have provided an exemplary embodiments of the utility model reverse osmosis water purifier, and this water-purifying machine comprises water inlet pipe 1, pre-filter core 2, charcoal filter core 3, reverse osmosis membrane 4, flow-limiting valve 6, outlet valve 8, low water switch 11, water tank 13, float switch 15 and pilot circuit; This water-purifying machine also comprises ozonizer 5, entering water electromagnetic valve 9, scouring electromagnetic valve 10 and electromagnetic pump 12; Above-mentioned each parts all directly or indirectly are installed on the underframe 16; Wherein water inlet pipe 1, entering water electromagnetic valve 9, pre-filter core 2, charcoal filter core 3, low water switch 11, electromagnetic pump 12, reverse osmosis membrane 4 and water tank 13 interconnect with pipeline successively; Reverse osmosis membrane 4, flow-limiting valve 6 and scouring electromagnetic valve 10 interconnect with pipeline successively; Described ozonizer 5 and outlet valve 8 interconnect with pipeline and water tank 13 respectively; Float switch 15 interconnects with water tank 13 and pilot circuit respectively; Ozonizer 5, entering water electromagnetic valve 9, scouring electromagnetic valve 10 and electromagnetic pump 12 are connected with pilot circuit by circuit respectively.

The present embodiment water purification is provided with additional water and chews 17 on water tank 13.Sequence number 14 is a circuit control panel among the figure.

The working process of the utility model water-purifying machine is described below: connect the 220V alternating-current with embodiment, the tap of fetching boiling water, tap water is through water inlet pipe 1, entering water electromagnetic valve 9, the pre-filter core 2 of water inlet, polypropylene spray fusing fiber pre-flock through 20 μ m, be mainly used in the silt in the filtering water, impurity etc., enter charcoal filter core 3 then, this charcoal filter core has three layer filtration, and the first layer is the polypropylene spray fusing fiber of 10 μ m, and the second layer is the high-quality active fruit shell carbon, its granularity is the 28-40 order, chlorine residue in the main planar water, organism thoroughly removes heterochromatic, peculiar smell in anhydrating.The 3rd layer is the polypropylene melt fiber of 5 μ m, and this filtering layer is used for the impurity of further filtering water.Enter electromagnetic pump 12 through the water after the total filtration of charcoal filter, because the pressure of water is opened low water switch 11, electromagnetic pump 12 is started working, and ducted water pressure raises, and enter reverse osmosis membrane 4, reverse osmosis membrane adopts polymeric amide ultralow pressure reverse osmosis membrane, and its filtering accuracy is 1,000,000/millimeter, the inorganic salt in the energy filtering water, carbohydrate, amino acid etc., behind reverse osmosis membrane filtration, pure water flows into water tank 13 from pure water inlet and deposits.Dense water flows to flow-limiting valve 6 and scouring electromagnetic valve 10 respectively through dense water out, and the water of the flow-limiting valve of flowing through is discharged from delivery pipe, and flow-limiting valve adopts the micropore flow restriction, can improve the pressure in the management road, makes reverse osmosis membrane go out water purification.Scouring electromagnetic valve 10 the system water conservancy project as the time close, behind water tank system full water, float switch 15 rises, and opens switch, and scouring electromagnetic valve 10 is opened, water is directly broken through from reverse osmosis membrane, water is walked around flow-limiting valve 6 and is discharged from delivery pipe through scouring electromagnetic valve 10, and the dirt in the reverse osmosis membrane 4 is gone out with water, washes to stop automatically after 5 seconds, close entering water electromagnetic valve 9 simultaneously, complete machine quits work.Behind the water tank system full water, ozonizer 5 is started working automatically for the first time, and the pure water in water tank is squeezed into ozone gas, to reach the purpose of sterilization fresh, closes after 20 minutes, works 20 minutes automatically every 24 hours later on.When in the water tank water being arranged, open outlet valve 7, just can from rising pipe, receive pure water.When complete machine had the system water conservancy project to do, if cut off the water suddenly, then machine can quit work automatically, and having additional water to chew 17 under the water tank can intake to water dispenser automatically.
