Description

A kind of pressure-controlling water-saving type RO purifier

Technical field

The utility model relates to family's water purifying plant, relates in particular to a kind of pressure-controlling water-saving type RO purifier.

Background technology

In the market with the water purification machine of pressure water storage barrel, comprise that all there are the bigger problem of wastewater discharge in common 50G reverse osmosis water purification machine or 75G reverse osmosis water purification machine, may occur 5: 1 in actual use even higher waste water ratio, when especially each water consumption was less, the waste water of generation was big more.In addition, water receiving will make topping-up pump start continually and influence its work-ing life repeatedly.Be the working condition of simulation machine in daily use, the waste water ratio during the test machine real work, test in the following way:

1. after the full high pressure take-off of machine pressure water storage barrel water, gently press the pure water tap to open the pure water tap, emit pure water 540ml, the back machine take-off of loosing one's grip is started working, and presses stopwatch, collects all waste water.After the full high pressure take-off of machine pressure water storage barrel water, stop timing, the waste water total amount that metering is collected, the record total run time calculates pure water average discharge and waste water ratio in this 500ml pure water system water process.

2. as above, after the full take-off of pressure pot water, emit pure water 600ml, 1350ml, 2000ml, 3000ml, 5000ml, 9000ml successively, collect the full high pressure of the pressure pot water that at every turn discharges water all waste water during the take-off once more, and timing, calculate the actual waste water ratio of user when disposable water is these flows, and tabulate and add up, shown in the following expression.

Waste water is than test and result under table 1:50G and the 75G reverse osmosis water purification machine actual condition

Find out from the measuring result of last table statistics:

1. disposable water is few more, and waste water is higher than more, and along with disposable water consumption increases, average waste water is than lacking more, but pure useless ratio all is higher than 1: 3.

2. 50G pressure pot work total volume is 9.4L, and the waste water ratio was 1: 3.7 when empty bucket was made water.

3. 75G pressure pot work total volume is 9.2L, and the waste water ratio was 1: 3.1 when empty bucket was made water.

Therefore, there is the problem of serious waste water in existing reverse osmosis water purification machine, especially exists disposable water few more, and the waste water ratio is high more, the serious more problem of wasting water.

The utility model content

Technical problem to be solved in the utility model provides a kind of pressure-controlling water-saving type RO purifier, has deficiency to overcome prior art.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of pressure-controlling water-saving type RO purifier, prefiltration device, preposition low-tension switch, entering water electromagnetic valve, reverse osmosis filter are installed in its pipeline, high-voltage switch gear, pressure water storage barrel, rearmounted charcoal filter and depotition cock, described preposition low-tension switch, entering water electromagnetic valve, high-voltage switch gear all are electrically connected with computer box, it is characterized in that: also comprise being electrically connected with computer box being used for monitoring pressure water butt aquifer yield and making the rearmounted low-tension switch of computer box according to monitoring result start and stop water purification machine.

Described rearmounted low-tension switch is arranged between pressure water storage barrel and the post active carbon.

In order to make water purification machine can adapt to normal system water under the low condition of pressure, the described topping-up pump that before osmosis filtration, also installs additional.

Adopt technique scheme, owing to increased the rearmounted low-tension switch of monitoring pressure water butt aquifer yield, and control the start and stop of water purification machine according to monitoring result by computer box, just start the work of making pure water after so just making water purification machine emit the pure water of specified amount at pressure water storage barrel, avoided causing water purification machine to start the shortcoming that the system water conservancy project is done once opening depotition cock (being that pressure water storage barrel one is emitted pure water), and then avoided few and the problem that the discharge of wastewater ratio is high of disposable water, can accomplish to make water purification machine to do with minimum discharge of wastewater ratio system water conservancy project all the time, thereby greatly reduce the waste of water.Therefore, to solve disposable water few and problem that the discharge of wastewater ratio is high has the advantage of water saving for the utility model.
