Description

A waste water reuseing machine of reverse osmotic pressure clean water machine

The present invention relates to a wastewater recycling apparatus of a reverse osmosis water purifier for eliminating waste of wastewater discharged essentially from a water purifier for a reverse osmosis system.

Currently, the reverse osmosis water purifier that has been developed and used is known to be superior to other water purification methods developed so far in removing contaminants.

The reverse osmosis water purifier is a purified water → sediment filter → single stage detection switch → raw water valve → boost pump → sun carbon filter → membrane filter → fu carbon filter → sterilization lamp → bio ceramic filter and becomes purified water in order of cold water tank and hot water tank. Is stored.

Wastewater separated from the membrane filter is drained out through the flow rate resistor.

However, since the membrane filter is separated into purified water and wastewater and the wastewater is discharged as it is, there is a problem in that a large amount of wastewater cannot be recycled.

Therefore, in order to solve the above problems, Korean Unexamined Utility Model Publication No. 99-6727 'Waste water recycling apparatus for reverse osmosis water purifier' has been proposed.

That is, the wastewater recycling apparatus of the reverse osmosis water purifier includes a sedimentation filter 12, a sun carbon filter 13, a fucarbon filter 15, and a brain filter 14, as shown in FIG. Connecting to the filter unit 1, the single stage detection switch 2 in series to increase the water pressure of the filter unit 1, and to sterilize the purified water generated in the filter unit 1 Cold and hot water tank 17 to allow the user to use as much as necessary according to the control of the check valve 19 and the purified water passed through the sterilization lamp (4) and the sterilization lamp (4) and the bioceramic filter (16). And a purified water tank unit 5 having an 18, and receiving wastewater separated and separated from the membrane filter 14, by an electric signal, to the inlet side of the flow rate resistor 6 or the boosting pump 3 selectively. Outflowing three-way 21, the membrane filter 14 is separated from the discharged waste water to one outlet Controller 22 for controlling the three-way side 21, the boosting pump 3 and the three-way 21 so that the raw water is prevented from flowing back to the three-way side 21 from the inlet side of the boosting pump (3) It consists of a check valve 23 provided between.

Accordingly, the wastewater recycling apparatus of the reverse osmosis water purifier configured as described above is connected to the check valve 23 with the wastewater discharged from the three-way valve 21 in the state where the water level detection switch 2 is opened, and then the boost pump 3 When the flow path is formed at the front end of the c), all the pipes from the front end of the boost pump 3 to the raw water inlet are formed with raw water supply pressure, and according to the high and low pressures, the following irrational phenomenon occurs. do.

First, when the pressure of the raw water is higher than the wastewater discharge pressure, the wastewater passing through the three-way 21 can not pass through the check valve 23 to increase the pressure inside the membrane filter 14 to the membrane filter 14. It can cause fatal damage.

Second, when the pressure of the raw water is lower than the discharge water discharged from the three sides, the wastewater may pass through the check valve 23, but the wastewater receives resistance as much as the raw water pressure, which is a characteristic of the membrane filter 14. We do not expect the proper ratio of waste and water.

Third, the wastewater discharged from the three-way side 21 is connected to the check valve 23 in the state where the water level detection switch 2 is closed to block the supply of raw water, and then the pipe is connected to the front end of the boost pump 3. Although the raw water pressure is not formed from the stage detection switch 22 to the front end of the boost pump 3 when the inlet is formed, the discharge volume (waste water and water purification) of the boost pump 3 is larger than the waste water returning from the closed piping condition. The inside of the pipe to the front end of the switch 2 and the boost pump 3 is formed with a vacuum pressure, which makes it impossible to discharge the boost pump 3 itself.

At this time, the inside of the pipe should be maintained at the atmospheric pressure at all times, the booster pump 3 of the normal water purifier does not have a suction lift capability and is supplied with water at the raw water pressure and has only a pressure discharge function.

Fourth, raw water supply pressure is not the same according to the region or time of use of the water purifier, so it is impossible to predict any of the first to third conditions.

Of course, even if all the above problems are solved, it is unreasonable to control the operation time of the singular detection switch 2 or the trilateral direction to an arbitrary time of 8 minutes depending on the length and length of the time. This is not possible because the control time has to be determined in relation to filter contamination, pump performance and raw water pressure.

For example, when the control time (8 hours) is long, the state of blocking the raw water is maintained, the inflow of waste water is depleted (stopped), and the boosting pump 3 fills the water level of the water purification tanks 17 and 18. The continuous hollow rotation occurs, and when the control time (8 hours) is short, the single stage detection switch 2 is opened to supply the raw water and the wastewater tries to be drawn in, causing serious damage to the membrane filter.

Therefore, the present invention is to eliminate the waste water discharged from the water purifier of the reverse osmosis method to solve the above problems.

The present invention for achieving the above object is a sediment filter for removing rust components and suspended solids contained in the water flowing through the raw water supply hose, and the water filtered by the sediment filter is pressurized through a water supply pipe In the reverse osmosis water purifier, which is transmitted to a sun carbon filter and a membrane filter by a pump, and the purified water separated by purified water and wastewater by the membrane filter is stored in a purified water tank via a fucarbon filter. A waste water return bottle is installed between the filters, one side of the waste water return bottle is connected to a water supply pipe connected to the precipitation filter, and a return pipe for discharging the waste water separated from the membrane is extended to the other side, and one end of the water supply pipe Maintain a constant water level by the water level sensing device, characterized in that the pressurized pump is installed on the lower side.

Extended return pipe 410 for discharging wastewater And maintains a constant water level by the water level detecting device 800 at one end of the water supply pipe 110, and a pressure pump 200 is installed at a lower side thereof, thereby giving a technical configuration feature thereof.

As shown in FIG. 3, the waste water container 700 has an upper portion of the body 710 having a space 701 formed therein for receiving raw water and waste water, and an upper side of the body 710. A raw water connector 720 connected to the water supply pipe 110 is formed, and a waste water supply port 730 connected to the return pipe 410 is formed at a side corresponding thereto, and the raw water contained in the space portion 701 at the bottom thereof. And a connecting pipe 740 for connecting a pressurized pump 200 for supplying wastewater at a predetermined pressure to each filter, and an air passage 751 formed at an upper end of the opening to form a constant atmospheric pressure. It is configured to be covered.
