The present invention is equipped with a membrane filter and a manual pump integrally mounted inside the pressure vessel without using a pump equipped with a power motor, so that it can be easily carried for leisure or emergency in mountains or the sea, and thus cleans a wide range of raw water from fresh water to sea water. It relates to a portable water purification device that can be 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 filter is in the form of a scroll with a collecting pipe in the middle, and fine pores of about 0.01 μm or less are formed on the surface of the membrane to purify water, and the salt removal efficiency is generally 98% or more. If the raw water to be purified is pumped into the pressure vessel, the pure water is discharged through the collecting pipe, and the concentrated water that has not passed through the membrane is discharged to a separate concentrated water outlet. The indentation force depends on the concentration of the solution. If this is indicated roughly, pressure of about 7 to 21 bar for surface water or ground water, about 15 to 41 bar for brine, and about 22 to 56 bar for seawater is required.

For this reason, the reverse osmosis water purifier must be continuously applied with an osmotic pressure or higher to obtain purified water quality above the proper standard value. Therefore, the power motor is attached and the centrifugal type or two or more piston pump chambers are attached to the reverse oscillating crankshaft. This pump has been used, and the pump pressure is also changed according to the concentration of raw water, and a membrane filter and a water purifier equipped with a pump are used.

Especially in case of portable water purifier without power motor, it is mainly used for low pressure water purification such as surface water or ground water which does not contain salinity due to continuous pressurization and weakness of pump connection part and driving method according to manual pumping action. In addition, there is a problem that can not be purified to salt water or salt water that requires high pressure by a high driving force.

 In order to solve the problems as described above, the present invention is designed to be easily 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.

Membrane filter with high removal efficiency and wide range of operation from low pressure to high pressure and water purifying capacity inside the pressure vessel, and manual piston pump that continuously drives two piston pumps in the form of seesaw by vertical operation of driving lever. Its purpose is to provide a portable water purification device designed to be used as living water or drinking water by treating the wide range of raw water from fresh water to sea water by minimizing container damage and leakage by high pressure.

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

1 and 2, the portable water purifying apparatus according to the present invention will be described. A lever fixing shaft 21 is attached to the upper pressure vessel 19, and a predetermined interval point of one end of the drive lever 11 is provided. The first piston pump and the second piston pump are installed on the left and right sides of the lever fixing shaft 21, and the driving lever 11 and the piston 12 are connected by the connecting rod 22.

In addition, a raw water inlet connector 34 is mounted on one side of the upper pressure vessel 19, and a pressure gauge 36 and a relief valve 37 for releasing excessive pressure are mounted on the opposite side thereof.

Cylinders 15 are mounted on the front and rear ends of the upper portion of the upper pressure vessel 19, respectively, and check valves are mounted on the lower side of each cylinder 15 and connected to the raw inlet connector 34. The cylinder 15 is provided to form a flow path, and the packing 14 is mounted on the upper portion of each cylinder 15 to maintain the airtight, and the packing support 13 is screwed thereon.

The roll-type membrane filter 27 having the brine seal 26 attached to the pressurized side is mounted inside the lower pressure vessel 20, and the membrane is provided at the fresh water port 28 on the pressurized side to which the brine seal 26 is attached. The guide cap 24 is sealed by the O-ring 25 so as to fix the filter 27 and prevent the raw water from flowing into the fresh water port 28, and the end cap 30 is provided at the opposite fresh water port 28. The raw water is sealed and installed by the O-ring 25 so that the water does not flow into the fresh water port 28.

The outer circumference of the end cap 30 in which the brine outlet 31 and the fresh water connector 33 are installed is sealed by the O-ring 25 and fixed to the lower pressure vessel 20 and the fixing ring 29 so as not to be separated. The O-ring 25 is mounted on the pressure side outer circumference of the lower pressure vessel 20 and inserted into the lower portion of the upper pressure vessel 19 so as to slide, and is fastened to the pressure vessel fixing bolt 23.

Referring to the operation of the portable water purification device configured as described above according to the flow path, by lifting the drive lever 11 mounted on the upper pressure vessel 19, the lever fixed shaft 21 and the first piston connected to the drive lever 11 The piston 12 on the side of the first piston pump 51 is pressed down by the connecting rod 22 of the pump 51 and the second piston pump 52 so that the raw water inlet connector 34 is checked. It is closed by the ball 16 and the check ball 16 of the lower cylinder 15, while pressing the spring 17, the raw water in the cylinder 15 is introduced into the pressure vessel. In addition, as the piston 12 on the second piston pump 52 side is lifted and expanded, and the inside of the cylinder 15 is in a vacuum state, the check ball 16 on the raw water inlet connector 34 side sucks raw water and springs. Press (17), through which the raw water is introduced into the cylinder (15).

On the contrary, when the driving lever 11 is pressed, the piston 12 of the first piston pump 51 is expanded and the piston 12 of the second piston pump 52 is pressurized to operate in a seesaw form.

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 34 passes through the membrane filter 27 by a pressure greater than the osmotic pressure and the fresh water port 28. The purified water is collected and discharged through the fresh water connector 33, and the purified water is not discharged to the outside through the pressure control valve 32 of the concentrated water outlet 31.

The pressure regulating valve 32 serves to adjust the pressure to maintain the pressure above the osmotic pressure in accordance with the concentration of raw water in the pressure vessel, the pressure gauge 36 displays a constant pressure that is purified according to the concentration of raw water to maintain a continuous pressure In order to smoothly control the operation of the drive lever 11, the relief valve 37 serves to release it when an abnormal pressure occurs due to excessive operation of the drive lever (11).
