Description

Apparatus of filtering water

The present invention relates to a water filtering device, and more particularly, by forming a hole in the lower cover at one end of the carbon filter, and installing a cover film in the hole, so that water does not pass through the hole, and only air passes. Thus, by adjusting the pressure inside and outside the filter, the present invention relates to a water filtering device for filtering and drinking water in a closed container.

Generally, water is divided into natural water and purified water. Natural water refers to all water that exists naturally such as snow, water, rainwater, light water (well water), soft water (reservoir, lake, river water), and mineral water. It means modified water.

The device for supplying the purified water is called a water purifier and can be classified into a natural filtration type, a direct filtration type, an ion exchange water type, a distillation type, or an inverse osmosis type depending on the principle and method of purification. Such drinking water can be supplied directly through a water purifier or bottled water. You can also buy bottled water in disposable PET bottles or drink bottled water in a water bottle while traveling outdoors without a water purifier or water heater.

However, if you take the purified water in advance, the weight is not only burdensome but also the amount is limited. In addition, there are many cases in which water flowing in the nature and the tundra water can not be used as potable water due to deepening of environmental pollution. Therefore, there is a need for a portable water purifier that can be simply filtered and used as drinking water anywhere.

However, when the water is purified by combining the filter with the portable water bottle, the air in the filter is sucked out through the filter when the water is sucked, and the pressure inside the filter is different from that of the filter.

Therefore, the problem to be solved by the present invention is to form a hole in the lower cover at one end of the carbon filter, and by installing a cover film in the hole, so that water does not pass through the hole, only the air passes through, By adjusting the internal and external pressure, it is to provide a water filtering device for filtering and drinking the water in a closed container.

1 is a configuration diagram of a water filtering apparatus according to a preferred embodiment of the present invention.

2 is a cross-sectional view of a water filtering apparatus according to a preferred embodiment of the present invention.

1 and 2, the water filtering apparatus according to the present embodiment includes a carbon filter 110, a membrane filter 120, a lower cover 130, a cover membrane 140, and an upper cover 150 do.

The carbon filter 110 has a hollow cylindrical shape in which a receiving portion 111 is formed in the longitudinal direction inside. An empty space is formed in the cylinder to allow the membrane filter 120 to be inserted therein. The carbon filter 110 is used for removing various kinds of chemical pollutants, and is particularly effective for removing organic chemicals such as pesticides, herbicides, and industrial wastes. It is also effective in removing radon, chlorine, and odor. When using a high quality carbon filter, 80 - 99% of unpleasant taste including organic chemicals, radon and chlorine can be removed.

The carbon in the carbon filter 110 is called activated carbon, and this kind of carbon is made of special heat-treated coal to form millions of fine holes. Thus, contaminants that were present in the water while passing through millions of holes are filtered. The quality of the carbon filter 110 is a difference in how small the pores can be produced by the technique of producing carbon into the carbon filter 110. That is, the higher the activity, the easier it is to filter out more impurities and to reduce the tunneling phenomenon where water flows only through a certain passage.

The membrane filter 120 is a filter for secondarily filtering the water that has passed through the carbon filter 110 and is inserted and fixed in the inner receiving portion 111 of the carbon filter 110.

The protrusion 121 is formed to fix the membrane filter 120 to the inner accommodating portion 111 of the carbon filter 110, and the protrusion 121 is formed on the upper cover 150. Can be combined.

As an example of the membrane filter 120, a UF (Ultra Filtration) hollow fiber membrane filter will be described.

The UF hollow fiber membrane filter is a porous filter with pores of several tens to several hundred nanometers (nm) in size. It passes through only a small number of micropores distributed on the membrane surface to remove contaminants present in the water. Hollow fibers are composed of several filament yarns like a thread with a hole in the middle, and since there are 100 billion microscopic pores in one hollow fiber, it can be used not only for domestic water purifiers but also for industrial wastewater treatment, ultrapure water manufacturing process and medical artificial elongation It is a filter which is applied variously to various purposes.

Recently, it has been widely applied as a filter for removing bacteria, viruses and particulates. Since the size of pores on the membrane surface is about 0.001 to 0.01 microns (1 / 100,000 to 1 / 10,000 of the thickness of a human hair), it removes impurities such as bacteria, viruses and particulates, but does not filter beneficial substances such as minerals, It has a filtering function.

On the other hand, the type of the membrane filter 120 can be classified as follows depending on the size of the contaminants that can be separated from the membrane.

RO (Reverse Osmosis) removes more than 0.0001 micron particles. It has a pore size of 0.0001 micron and exhibits a high removal rate for ionic substances, as well as the removal of suspended solids, microorganisms, common organic compounds and heavy metals.

NF (Nano Filtration) removes more than 0.001 micron particles. It is also called ultra pure water filtration or nano filtration and is called membrane softening. Nanofiltration exhibits high removal rates for divalent ions such as calcium and magnesium.

UF (Ultra Filtration) removes 0.0015 - 0.1 micron particles or more. Also called ultra-fine filtration or ultrafiltration, when the pore size is less than 0.1 micron, the water pressure required to maintain constant water constant also increases simultaneously. In the case of ultraprecision ultrafiltration, the required water pressure is about 1.4 kg / cm because the pore size is quite small, from 0.0015 to 0.1 micron.

MF (Micro Filtration) removes 0.1 - 1.0 micron particles or more. Also known as microfiltration, it removes suspended matter or microorganisms of 0.1 to 20 microns and serves as a membrane with membrane pores in the simplest way during the membrane separation process.

The water that has passed through the membrane filter 120 is water that can be consumed by the user.

The lower cover 130 blocks one end of the carbon filter 110 or the membrane filter 120. At least one hole is formed in the lower cover 130 so that air can be introduced and removed. However, since the water that has not passed through the carbon filter 110 or the membrane filter 120 may pass through the hole, the cover membrane 140 is installed on one surface of the lower cover 130. [ At this time, it is preferable that the cover membrane 140 is installed on the opposite side of the surface of the lower cover 130 to which the carbon filter 110 or the membrane filter 120 is coupled.

The reason for forming the hole in the lower cover 130 is to balance the pressure inside the carbon filter 110 or the membrane filter 120 with the external pressure. When drinking water that has passed through the carbon filter 110 or the membrane filter 120, the pressure inside the filter becomes lower than the external pressure, and it becomes difficult to continuously suck water. Therefore, the pressure is balanced through the hole The cover film 140 is formed so that the water is not filtered and can not pass through.

The cover 140 is formed of a silicone material so that water can not pass through the hole formed in the lower cover 130. The cover membrane 140 is brought into close contact with the lower cover 130 to prevent water from flowing into the carbon filter 110 or the membrane filter 120 through the hole formed in the lower cover 130 When the air is blown into the carbon filter 110 or the membrane filter 120, the air can escape through the holes formed in the lower cover 130.

The protrusion coupling portion 141 located in the center of the cover film 140 for coupling the cover film 140 and the lower cover 130 is preferably hollow. When the inside of the protrusion coupling portion 141 is empty, the protrusion coupling portion 141 is condensed so that when the cover film 140 is fitted to the lower cover 130, the lower cover 130 and the cover film 140 are coupled It is convenient to do.

The protrusion coupling portion 141 of the cover film 140 is inserted into the hole of the lower cover 130 so that the cover film 140 and the lower cover 130 are engaged.

The upper cover 150 closes the other end of the carbon filter 110 or the membrane filter 120 and strengthens the coupling between the membrane filter 120 and the carbon filter. The upper cover 150 is provided with a recessed groove 151 for fixing the membrane filter 120.

When the membrane filter 120 is rotated by inserting the protrusion 121 of the membrane filter 120 into the recess 151 of the upper cover 150 and then the membrane filter 120 is inserted into the inner receiving portion 151 of the carbon filter 110, (Not shown).

3 is a cross-sectional detail view of a cover film according to a preferred embodiment of the present invention.

Referring to FIG. 3, a protrusion coupling portion 141 formed vertically in the middle of the blocking film 142 is shown.

The protrusion engaging portion 141 has an inner shape that is deformed when pressure is applied to the protrusion engaging portion 141 when inserted into a hole in the lower cover 130, thereby facilitating insertion.

The blocking membrane 142 allows only air to pass without passing water through the hole formed in the lower cover 130. When water is sucked in, the blocking membrane 142 is brought into close contact with the lower cover 130, so that the water outside the filter does not enter the inside of the filter, and air is discharged to the outside of the filter through the hole of the lower cover 130 , The pressure inside and outside the filter is balanced. In addition, although the shielding film 142 is shown as a circle in FIG. 3, it is not limited to this, and a polygon such as a quadrangle or a pentagon is also possible.

Referring to FIG. 8, the water suction device 610 according to the present invention includes an air inlet 800, an air membrane 810, an inlet 820, and an air inlet 830.

The air inlet 800 is a hole through which air can enter the water storage container 710. The balance between the internal pressure of the water storage container 710 and the external pressure can be adjusted through the air inlet 800. [

Since the air membrane 810 has the same function and shape as the cover membrane 140 shown in FIG. 3, detailed description thereof will be omitted. That is, when the air is introduced through the air inlet 800, the air membrane 810 is separated from the air inlet 800.
