Description

Filtration apparatus of water tank

The present invention installs a water purifier inside the water tank installed on the roof of a home or building, and removes foreign substances, bacteria, waterborne bacteria, etc. contained in the water supply from the water purification plant and cleans the water while supplying clean water. And a water tank for purifying the filter by draining the flow of water backward after a certain period of time.

In general, the water supplied to each household, restaurant, building, etc. from the waterworks is supplied to each household as it is mixed with various foreign substances generated by the pipe's aging or damage while moving along the pipeline. It is a well known fact.

In particular, in many homes and businesses, water tanks installed on the roof are stored for a long time with water mixed with the above foreign matters, and after a certain period of time, many foreign substances and rust and bacteria mixed in the water tanks, etc. It is a well-known fact that many diseases are caused by bacteria and bacteria in the unsanitary water in the summer, because all of them know that they are very unsanitary because they are largely deposited and they are not easy to clean frequently. .

The present invention has been devised in view of such a point and fills the inner bottom of the water tank with a filter formed of sand, gravel, activated carbon, etc. to purify the supplied water, and discharges the water flow backward after a certain period of time. By allowing the filter to be washed, it is possible to supply the purified water continuously.

In the FRP material water tank (3) provided with the inflow pipe (1) and the outflow pipe (2), a diaphragm (4) is provided above the inflow pipe (1) inside the water tank (3), and spaced below it. A perforated plate 6 provided with a plurality of strainers 5, 5 'is installed so that the upper part of the diaphragm 4 and the lower part of the perforated plate 6 communicate with the water pipes 7 and 7'. The upper surface of the stencil 6 is filled with a filtration filler 8 made of sand, activated carbon, etc., and a drainage tank 10 having a mesh plate 9 attached to the central upper surface of the diaphragm 4 is attached to the contaminated water discharge pipe ( 11) by observing.

In the figure, reference numeral 12 denotes a valve attached to the inlet pipe 1, the outlet pipe 2, and the contaminated water discharge pipe 11.

The present invention thus obtained is filtered based on the filler 8 for filtration such as sand activated carbon filled in the upper surface of the porous plate 6 when water supplied from the water purification plant flows into the inlet pipe 1 installed on the lower side of the diaphragm 4. The filtered water is discharged to the bottom of the porous plate 6 through the strainer (5) (5 ') installed in the porous hole of the porous plate (6) and the water is stored at the same time as the water pipe (7) (7') As it is raised above and stored in the water tank 3 of the upper part of the diaphragm 4, the stored water flows out through the outflow pipe 2, which flows into the upper part of the diaphragm 4, and is supplied to a kitchen of a home, as described above. Foreign substances, bacteria, etc. will be filtered to eat clean water removed.

Here, the filler 8 for filtration filled in the upper surface of the porous plate 6 is filled with a mixture of sand, gravel, activated carbon, etc., but the strainer 5, 5 ′ is provided in the porous portion of the porous plate 6. The filling material such as sand is caught on the strainer (5) (5 ') and is not permanently stacked on the top surface of the perforated plate (6), so as to continuously filter the water introduced into the inlet pipe (1). In addition to the above materials, it is also possible to use commonly used filter media such as anthracite.

On the other hand, the filtration filler (8) is used for a long time, the foreign matter and rust, etc. contained in the water is deposited and loses the filtration function, at this time, the inlet pipe (1) and outlet pipe (2) leaked into the water tank (3) When the valve 12 of the contaminated water discharge pipe 11 is opened while the valve 12 of the valve 12 is blocked, the water filled between the diaphragm 4 and the porous plate 6 is filled with the mesh plate of the drainage tank 10. 9) is discharged to the contaminated water discharge pipe 11 through the water discharged into the contaminated water discharge pipe 11, the water stored in the water tank (3) has a strong hydraulic pressure downward so that the perforated plate (6) is passed through the strainer (5) (5 ') in the reverse direction and is discharged to the polluted water discharge pipe (11) while passing through a strong water pressure between the filtration filler (8) filled on its upper surface for filtration in this process This contaminated water is generated because foreign matter and other impurities deposited in the filler material 8 are turbidly discharged. If you continue to discharge the stored water until it does not come to be able to carry out the contaminants and foreign matters deposited in the filter filler (8) without a separate washing operation.

When the above washing operation is completed, the valve 12 of the contaminated water discharge pipe 11 is again closed, and the valve 12 of the inflow pipe 1 is opened again to store water, and thus, the filtration filler 8 as described above. As a result, the pollutants are stored in a filtered state, thereby providing continuous clean water.

As such, the present invention filters the water in the water tank 3 by the filtration filler 8, so that clean water from which foreign substances and impurities are removed can be eaten, so that the filtration filler 8 is very hygienic and uses strong water pressure. It can be cleaned so that the water tank can be purified and filtered in the long run.
