WATER STORAGE TANK STRUCTURE FOR THE WATER PURIFICATION SYSTEM BY REVERSE OSMOSIS

BACKGROUND OF THE INVENTION 5

Field of the Invention

The present invention relates to a water storage tank with multiple water flow passages for a reverse osmosis water purifier and, more particularly, to a tank regulated by a mechanical lever positioner to control the water flow for keep the purified water in a soft bladder inside the tank and extract the purified water by residual water pressure. Waste water stored in the tank stops expanding and flows down to the drain when the bladder of purified water is full. A mechanical lever positioner detects the same water pressure of the reverse osmosis. The purifier then stops the production of water. After dispensing the purified water from the tap, the tank pressure drops and the lever positioner valve activates the residual water to flow into the tank and, thus, expels the purified water out. While the wastewater is drained to the outside, a larger volume of wastewater is available to wash the surface of the reverse osmosis membrane. An automatic shut-off valve or solenoid valve activates the reverse osmosis membrane element to produce purified water to the tank. Waste water cleanses the membrane and flows down into the drain. The method and operation circulate the purified water and wastewater for the system of

reverse osmosis water.

Description of the related technique

The conventional reverse osmosis water purification system 9 is disclosed in Fig. 5 14, in which the feed water at a preset pressure flows to the filter 91 of

the reverse osmosis membrane to separate the purified water from the drainage water. The ratio of purified water and drainage water is approximately 1: 4, which means one liter of purified water for every 4 liters of drainage water. There is a lot of residue. The purified water is stored in a pressurized tank with air 95 with a bladder 951 inside it keeping the pressurized water in the tank when it is full and expelling the water out when the water pressure is released.

To conserve water, the reverse osmosis water system has an automatic shut-off valve. When the storage tank 95 is full, the valve 92 prevents any additional water from entering the membrane 91 thus stopping the production of water. Closing the flow of this valve also prevents water from flowing into the drain. Once the water is obtained from the drinking water tap 97 for reverse osmosis, the pressure in the tank 95 drops and the automatic shut-off valve 92 opens, allowing the water to flow to the membrane 91 and the residual water to flow down to drain 96.

It is noted that the conventional reverse osmosis water purification system 9 generates a large amount of wastewater and can be improved. In addition, tank 95 is limited to an apparatus of a certain high feed water pressure area or to the addition of an auxiliary pump. Because the purified water pressure exceeds the

System back pressure, low pressure reverse osmosis membranes or optional membranes are excluded in the apparatus.

10 DESCRIPTION DETAIL OF THE PREFERRED EMBODIMENT

Referring to Figs. 1 to 5, the present invention relates to a water tank unit "A" of a reverse osmosis water purification system "B". The wastewater of the reverse osmosis water purification system "B" becomes the power to dispense the purified water from the water tank unit "A". The water tank unit "A" comprises a tank 1 having a chamber 11 defined therein, a soft bladder unit 3 being constructed in the chamber 11.

Multiple passages 111, 111a, 111b are defined through the upper part of the tank 1. The tank 1 has an open bottom 12 to which a lower cover 13 is connected. A recess 10 is defined in the upper part of the tank 1, so that it receives a control valve 2 inside. The control valve 2 is fixed by a fixing member 14. An upper cover 15 is mounted above the tank 1. A notch 16 is defined below the side of the recess 10, as shown in Fig. 5, the notch 16 serves to give space to

drain water passage so that it flows smoothly when the soft bladder unit 3 is full.

As shown in Figs. 3 and 6, the control valve 2 has multiple water passages, 5 which include the inlet passage of the drain water "a", the exit path of the drain water "b" and the passage of the inlet / outlet of the water purified "c". The previous 3 passages are connected to the gates 111, 111a, 111b at the top of the tank 1, respectively. The control valve 2 also has a valve body 21, a spring member 22 with a piston core 23 and a diaphragm unit 24. The spring member 10, the piston core 23 and the diaphragm unit 24 are installed sequentially in the dividing chamber 213 of the valve body 21.

The spring member 22 provides a spring force P3 to push the piston core 23. The control valve 21 has a body 210 and two side covers 211 and 212. The diaphragm unit 24 includes a film 241 and a seat 242 connected . The two side covers 211 and 212 are connected respectively to both ends of the valve body 210. The drain water passage "a" and the purified water passage "c" are located, respectively, in two side covers 211 and 212.

The outlet passage of the drain water "b" communicates with the interior of the body 210. The stepped hole 213 includes a first access 214 and a second access 215, in which the first access 214 communicates with the inlet path. of the drain water "a" and the second access 215 communicates with the drain path of the drain water "b". The piston core 23 has a first flow spacer 232, a second flow spacer 233 and a retaining seat 234. The valve piston core 23 is

located in the stepped hole 213, the first flow spacer 232 is located in the first access 214 and the second spacer 233 is located in the second access of the path. The piston core 23 is located in the stepped hole 213, the first spacer 232 is located at the first access 214 and the second spacer 233 5 is located at the second access 215.

As shown in Figs. 2 and 5, a soft bladder unit 3 is located in zone 11 of tank 1 and has a bladder 31 with an axial support shaft 32 connected therein. The axial support shaft 32 has a connection path 33 connected to the upper part thereof. The connection path 33 is connected to the purified water path "c", so that the purified water is dispensed from the soft bladder unit 3 through the purified water path "c" and the connection path 33. The bladder 31 accumulates a pressure level set by the purified water. Drainage water temporarily stored in tank 1, encompasses bladder 31, as shown in Fig. 7.

As shown in Fig. 6, a flow regulator 4 is connected to the connection portion between the inlet path of the drain water "a" and the zone 11 of the tank 1, and another flow regulator 4a is connected to a connecting portion between the path of the inlet of the drain water "a" and the first access 214. The flow regulator 4, 4a prevents the drain water from entering the water tank unit "A" or the first access 214 due to excessive water pressure.

As shown in Figs. 4 and 7, The water tank unit "A" cooperates with a filter

5, a first filter 6, a filter unit 61, an automatic shut-off valve 62, a second filter 7, a 4-way connector 73, a drain pipe 82 and other pipes to assemble the osmosis water purification system Inverse "B" of the present invention. The inlet 51 of the filter 5 is connected to the first filter 6, the outlet 52 of the filter 5 5 is connected to the purified water path "c" of the water tank unit "A" and the second filter 7 via the 4-way 73. The drain water outlet 53 of the filter 5 is connected to the drain water inlet path "a" of the water tank unit "A".

The "B" reverse osmosis water purification system of the present invention uses low pressure and medium pressure to cooperate with the feed water source with preset pressure, so that an auxiliary pump is not required to send the water from The source of feed water. When the water from the source of the feed water flows to the filter 5, the present invention processes the water and generates purified water 15 and drain water. Purified water and drainage water flow respectively through holes 111b and 111 through the path of purified water "c" and the inlet path of drainage water "a" of the water tank unit "A ". The purified water flows to the bladder 31 to form the purified water area by a connection path 33 and the drain water encompasses the bladder 31 inside the tank 1 to form the waste water area 20.

As shown in Figure 8, the purified water flows through the purified water path "c" and the pressure P2 in the purified water area pushes the second part 233 to the left to communicate the exit path of the water from drain "b" and hole

111a, so that drain water enters the second access 215 and the first access 214 through the hole 111a. The drain water then flows to the drain line 82 through the drain path of the drain water "b". If the pressure P2 is less than the spring force P3, the piston core 23 moves to the left to close the communication between the drain water outlet path "b" and the hole 111a, as shown in the Fig. 6.

As shown in Figs. 4 and 9, when the bladder 31 is completely filled with purified water and has a pressure P2 to close the valve 62, as shown in Fig. 4 to 10 through the path of the purified water "c", a diaphragm piece 621 in the automatic shut-off valve 62 it stops the feed water towards the filter 5. This stops both the production of purified water and drainage water. The water tank unit "A" has a small amount of drainage water inside.

15 As shown in Figs. 4 and 9, when the dosing tap 72 is open, the purified water in the water tank unit "A" flows to the second filter unit 71 and through the tap 72 by the force created by the amount of drainage water entering the drainage water area to the water tank unit "A" and the accumulation force compresses the bladder 31, with the bladder 31 having a pressure P2 stored therein, so that the purified water is expelled out of bladder 31 through the path of purified water "c". The pressure P2 then drops and activates the reverse osmosis water purification system "B" to produce purified water again. The drain water flows into the water tank unit "A" through the holes 111, 111a and the inlet path of the drain water "a". The pressure in the area of the drainage water is established

by the inlet of the drainage water so as to maintain the compression of the soft bladder unit 3 to dose the purified water until the tap 72 is closed. The water tank unit "A" is then in the state of producing water purified as shown in Fig. 8.

5

As shown in Fig. 10a, to prevent the water tank unit "A" from exploding due to high pressure due to automatic shut-off valves 62, 63, a regulating valve 4b is connected to the connecting pipe "d" connected between the drain water outlet path "b" and the purified water path "c". This means that when the pressure in the water tank unit "A" is too high, the pressure P2 of the purified water is able to activate the regulating valve 4b, and a portion of the purified water is released through the path drain water outlet "b" to prevent water tank unit "A" from being damaged by high pressure.

15 As shown in Fig. 11, which shows a reverse osmosis water purification system "B1" that is connected to a water tank unit "A", the difference between the reverse osmosis water purification system "B" and the reverse osmosis water purification system "B1" is that the automatic shut-off valve 63 and the 3-way connector 74 used in the reverse osmosis water purification system 20 "B1" are used for supply water source with a specific pressure, without

No auxiliary pump The "B1" reverse osmosis water purification system is capable of producing purified water.

As shown in Fig. 12, which shows a water purification system by

reverse osmosis "B2" that is connected to the water tank unit "A", the difference between the reverse osmosis purification system "B2" and the reverse osmosis water purification system "B1" is that the system reverse osmosis purification "B2" uses a pressure switch 64 or a solenoid valve and an auxiliary pump 65. The 5 pressure switch 64 or solenoid valve and an auxiliary pump 65 are electrically connected to the electrical control module 81 and the power source 8. The reverse osmosis water purification system "B2" uses the auxiliary pump 65 to supply the water from the feed water source and generates a preset pressure. Water with the preset pressure pushes a 631 diaphragm into the self-closing valve

10 63 and flows to filter 5, so that it produces purified water and drainage water. He

purified water and drainage water, respectively, flow into the water tank unit "A" through the purified water path "c" and the inlet path of the drain water "a".

15 When the water tank unit "A" is completely filled with water, the pressure P2 of the purified water is applied to the diaphragm 631, which blocks the path of the water pumped from the source of the water supply so that it does not enter the filter 5, and a water pressure builds up. When the pressure switch 64 detects the pressure, the electrical control module 81 will close the solenoid valve and the pump 65.

twenty

When the water tank unit "A" doses water, the pressure in the automatic shut-off valve 63 drops, so that the water from the water source can close the automatic shut-off valve 63 and flow to the filter 5. When the pressure switch 64 detects the low pressure, the electric control module 81 activates the pump 65, so that it allows

25

that water from the water source flows to the filter 5 through the automatic shut-off valve 63, to produce purified water and drain water. Purified water and drainage water are stored in the water tank unit "A". The circulation makes the reverse osmosis water purification system "B2" work properly.

As shown in Fig. 13, the method of operation of the water tank unit "A" comprises:

• a step (a) of installing drainage and purified water paths: prepare a water tank unit "A" that has a tank 1, an inlet path of the drain water "a", an exit path of the drain water "b" and a path of purified water "c" that are defined in tank 1;

• a step (b) of installing a soft bladder unit 3: install a soft bladder unit 3 in tank 1 to store purified water inside, and

• a step (c) of installing a control valve: installing a control valve 2 between the drain water inlet path "a" and the drain water outlet path "b", communicating the control valve 2 with the path of the purified water "c" and controlling the drainage water and the purified water to introduce it into and extract it from the water tank unit "A".
