Background Art Generally, foul water and wastewater has been purified by use of chemicals, such as chlorine, in the prior art. However, economical microbial purification methods have been preferably used for water purification in recent years.

In the conventional microbial purification methods, oxygen must be continuously supplied into a bio-filtering reservoir, otherwise the propagation of the microorganisms which live in a variety of filters of the bio-filtering

reservoir cannot be achieved. To supply oxygen to the bio- filtering reservoir, aeration stones or aeration pipes are provided in the bio-filtering reservoir and feed oxygen, such as highly pressurized oxygen, from an air blower or an air compressor to the reservoir. However, when supplying the oxygen to the bio-filtering reservoir by use of the aeration pipes or etc. , air bubbles generated from the aeration pipes cannot be maintained in objective water for sufficient period of time, but pop up out of the water within several ten seconds due to water pressure, thus being dispersed into atmospheric air.

Disclosure of the Invention Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a device for mixing and feeding negatively charged oxygen ions and magnetized hexagonal water, thus maximizing the amount of the negatively charged oxygen ions dissolved in the magnetized hexagonal water and effectively purifying objective water contaminated with foul water and wastewater.

More preferably, the first and second permanent magnets 186 and 96 may be attached to the lower surface of the second housing 182 and the upper surface of the third housing 190, respectively. The above-mentioned first, second and third housings 172, 182 and 190 are fastened together by a plurality of third locking bolts 199 which are fastened to the third housing 190 after sequentially passing through the first and second housings 172 and 182.

The operation of the above-mentioned device for mixing and feeding negatively charged oxygen ions and magnetized hexagonal water will be described in brief herein below.

When the controller 138 operates the oxygen generator

156, atmospheric air is introduced into the air cleaner tank 152 wherein impurities are removed from the inlet air. After the impurities are removed from the air, the air is fed into the activated carbon tank 154 wherein the air is first purified and then fed into the oxygen generator 156. The oxygen generator 156 generates negatively charged oxygen ions from the inlet air, and guides the negatively charged oxygen ions to the first and second zeolite tanks 158a and. 158b.

The first and second zeolite tanks 158a and 158b completely remove nitrogen from the negatively charged oxygen ions, and feed the negatively charged oxygen ions to the oxygen path 114.

In the meantime, the tormalines 176 are in contact with water, thus holding water therein. When the tormalines 176 which hold water therein come into contact with air, the tormalines 176 generate negatively charged oxygen ions which are guided to the oxygen path 114 while sequentially passing through the second oxygen inlets 180 and the first oxygen inlets 122.

When the negatively charged oxygen ions are contained in the oxygen path 114, the controller 138 operates the mixing motor 132. Thus, the mixing shaft 140 rotates along with the impeller 142. When the impeller 142 which is mounted to the mixing shaft 140 rotates as described above, the negatively charged oxygen ions are guided from the oxygen path 114 to the impeller 142 while sequentially passing

through the first oxygen inlets 122, the second oxygen inlets 180 and the third oxygen inlets 188. In the above state, some of the negatively charged oxygen ions, which have flowed through the third oxygen inlets 188 into the impeller depression 194 having the impeller 142 therein, are dissolved in magnetized hexagonal water which has been produced by the first and second permanent magnets 186 and 196 from water that has been introduced into the impeller depression 194 through the water inlets 198. The remaining ions of the negatively charged oxygen ions are discharged to the outside through the discharge holes 197 while being atomized.

In the meantime, when the tormalines 176 come into contact with, oxygen, the tormalines 176 cause electrolysis in the water because the tormalines are positively charged (+) and negatively charged (-) due to natural characteristics thereof, so that water molecules are decomposed into hydrogen ions and hydroxide ions. During the electrolysis, the positive charged hydrogen ions migrate to the negative electrode (-), and are linked to electrons, so that the hydrogen ions are neutralized and deformed into hydrogen valence hydrogen gas which is maintained in an upper portion of the oxygen path 114. However, the hydrogen valence hydrogen gas is discharged from the upper portion of the oxygen path 114 to the outside through the check valve 124, operated by the controller 138.

Industrial Applicability As described above, the present invention provides for the mixing and feeding negatively charged oxygen ions and magnetized hexagonal water. The device of the present invention selectively collects oxygen, which is contained in atmospheric air at a ratio of about 21%, from the atmospheric air, thus generating negatively charged oxygen ions. Furthermore, the device receives therein water through water inlets, and magnetizes the inlet water using first and second permanent magnets while swirling the water by use of an impeller, thus producing magnetized hexagonal water. Furthermore, the device dissolves the negatively charged oxygen ions in the magnetized hexagonal water by the impeller which rotates at a high rotating speed. Thus, the device maximizes the amount of the negatively charged oxygen ions dissolved in the magnetized hexagonal water, and effectively purifies foul water and wastewater.
