In the present invention, the reverse osmosis membrane and the manual pump are integrally mounted inside the pressure vessel without using a pump equipped with a power motor, and thus can be easily carried for leisure or emergency in mountains or the sea to purify a wide range of raw water from fresh water to sea water. The present invention relates to a portable reverse osmosis water purification device which can be treated and used as living water or drinking water.

Reverse osmosis is the separation of solutions with different concentrations that can dissolve with each other in a membrane. Osmosis occurs in the natural state, and the solvent of the solution with the lower concentration is exuded and moved to the higher concentration. It stops when all the solvent has passed or the head pressure on the high concentration side reaches a certain point. The point or state where osmosis stops is called osmotic equilibrium, and the difference in the head pressure on both sides is called osmotic pressure. The osmotic pressure is changed according to the concentration of the solution. It becomes possible.

The commonly used reverse osmosis membrane is in the form of a scroll with a collecting pipe in the middle, and a fine hole of about 0.01 μm is formed on the surface of the membrane to purify it, and the salt removal efficiency is generally removed by removing more than 98% When water is put into a pressure vessel and the raw water to be purified is pumped into the pump, pure water is discharged through the collecting pipe, and the concentrated water that has not passed through the separator is discharged to a separate concentrated water outlet. Silver depends on the concentration of the solution. If this is indicated roughly, the pressure is about 7 ~ 21 bar for surface water or groundwater, about 15 ~ 41bar for brine, and about 22 ~ 56bar for seawater.

For this reason, the reverse osmosis water purifier has been used with a pump equipped with a power motor, because it is necessary to continuously apply an osmotic pressure or more to obtain a purified water quality above an appropriate standard value. In addition, the pump pressure is changed according to the raw water concentration. Water purifier equipped with permeation membrane and pump is used.

Especially in case of portable reverse osmosis water purification device without power motor, it is mainly used for low pressure water purification such as surface water or ground water that does not contain salinity due to continuous pressure and weakness of container and connection part by manual pumping action. There was a problem in that the brine or sea water that requires high pressure cannot be purified into fresh water.

In order to solve the above problems, the present invention has been invented so that it can be conveniently used for leisure or emergency in mountains or the sea, and used as living water or drinking water by treating a wide range of raw water from fresh water to sea water.

To this end, the reverse osmosis membrane, which has a high removal efficiency, a wide range of use from low pressure to high pressure, and a hydrostatic capacity, a manual piston pump, and a gas tube filled with nitrogen gas, are integrally installed inside the pressure vessel. The portable reverse osmosis device was invented to absorb high pressure and maintain proper pressure as the gas tube is compressed, and to be restored at the time of intake of raw water by expansion of the piston pump, to maintain a certain part of the proper pressure, and to purify the water to a quality higher than the proper reference value. The purpose is to provide a water purifier.

In order to achieve the object described above will be described in detail by the accompanying drawings as follows.

1 and 2, the portable reverse osmosis water purifying apparatus according to the present invention will be described. One end of the driving lever 11 is connected to the lever fixing shaft 17 at the end of the upper pressure vessel 26. A piston 14 is connected to the drive lever 11 at the interval point, and a stopper 12 is attached to limit the up and down operating range of the drive lever 11.

In addition, a raw water inlet connector 38 is mounted on one side of the upper pressure vessel 26, and a pressure gauge 41 and a relief valve 43 for releasing excessive pressure are mounted on the opposite side thereof. The gas tube 22 filled with nitrogen at the pressure and the gas cap 19 having the gas injection valve 20 mounted on one side of the gas tube 22 are sealed by the O-ring 18 and are divided into three fixed rings ( 21) is fixed so as not to be separated from the upper pressure vessel (26).

A cylinder 16 is mounted at the center portion of the upper pressure vessel 26 and check valves are mounted on the lower side of the cylinder 16 and connected to the raw inlet connector 38 to form flow paths during pressurization and suction. The upper part of the cylinder 16 is provided with a packing 15 so that the piston 14 and the airtight are kept, and the packing support 13 is screwed on it.

The reverse osmosis membrane 30 with the brine seal 29 attached to the pressurized side is mounted inside the lower pressure vessel 27, and the reverse osmosis membrane with the brine seal 29 attached to the fresh water port 31 on the pressurized side. The guide cap 28 is sealed and installed by the O-ring 18 so as to fix the 30 and prevent the raw water from flowing into the fresh water port 31. The end cap 32 is provided at the opposite fresh water port 31. Is sealed with an O-ring so that the water does not flow into the fresh water port 31.

The outer circumference of the end cap 32 in which the concentrated water outlet 33 and the fresh water connector 36 are installed is sealed by the O-ring 18 and fixed to the lower pressure vessel 27 and the fixing ring 21 so as not to be separated. The O-ring 18 is mounted on the pressure side outer circumference of the lower pressure vessel 27 and is inserted to slide with the lower end of the upper pressure vessel 26 and fastened to the pressure vessel fixing bolt 27.

Referring to the operation of the portable reverse osmosis water purifying device configured as described above according to the flow path, when the driving lever 11 mounted on the upper pressure vessel 26 is lifted, the piston 14 connected to the driving lever 11 is lifted up. As the inside of the cylinder 16 is in a vacuum state, the check ball 23 on the raw water inlet connector 38 is sucked into the raw water, and the spring 24 is pressed, so that the raw water is introduced into the cylinder 16.

On the contrary, when the driving lever 11 is pressed, the piston 14 is pressurized and the raw water inlet connector 38 is closed by the check ball 23, and the check ball 23 at the lower portion of the cylinder 16 presses the spring 24. Raw water inside the cylinder 16 compresses the gas tube 22 and flows into the pressure vessel.

When the driving lever 11 is repeatedly operated in this way, a constant pressure is formed in the pressure vessel, and the raw water introduced through the raw water inlet connector 38 passes through the reverse osmosis membrane 30 by a pressure greater than the osmotic pressure and is a fresh water port 31. The purified water is collected and discharged through the fresh water connector 36, and the purified water is not discharged to the outside through the pressure control valve 35 of the concentrated water outlet 33.

The pressure regulating valve 35 adjusts the pressure to maintain the pressure above the osmotic pressure according to the concentration of raw water in the pressure vessel, and the gas tube 22 filled with nitrogen gas is subjected to water shock when the piston 14 is pressurized. It absorbs the pulsation and pressure caused by the pressure and serves to maintain a certain pressure inside the pressure vessel during expansion of the piston (14).

In addition, the pressure gauge 41 displays the proper pressure purified according to the concentration of the raw water to smoothly operate the driving lever 11 to maintain the continuous pressure, and the relief valve 43 is operated by the excessive operation of the driving lever 11. When abnormal pressure occurs, it releases it.

Referring to Figure 4 describes an embodiment used in connection with the component, by connecting the raw water inlet hose 46 to the pre-treatment filter 44, the strainer 45 is mounted on one side of the raw water inlet connector (38) And immersing the pretreatment filtration filter 44 in the raw water tank 49, the fresh water discharge hose 48 is connected to the fresh water reservoir 50, and the concentrated water discharge hose 47 is placed on the drain.

 When the driving lever 11 is operated, the raw water of the raw water tank 49 is introduced into the strainer 45 into the pretreatment filter 44, and the fine float and the like are firstly removed by the pretreatment filter filled with the cartridge type. Inhaled and pressurized by the container and passed through the reverse osmosis membrane 30 and purified water is stored in the fresh water storage tank 50 through the fresh water discharge hose 48 and the purified water is not purified water through the concentrated water discharge hose 47 Discharged to the drain.

As described above, the present invention has a cylindrical pressure vessel structure to use a reverse osmosis membrane, which is a general standard, and does not use a pump with a power motor, and reverse osmosis membrane, a manual piston pump, and a water shock when pressurized. The gas tube that can absorb pulsation and maintain a certain part pressure is integrated in the pressure vessel, minimizing vessel damage and leakage due to high pressure, and treating raw water from fresh water to sea water for purification. Or invented for use as drinking water.
