The present invention relates to a hepatic abnormality filtration device, and more particularly, to provide a clean water source as well as to provide a clean water source, as well as to easily maintain and clean the water, and to smoothly discharge the filtration water. It is about a simple tap water filtration device which can be discharged.

In general, in rural areas, a simple tap water filtration device is installed to pass valley water or ground water as raw water and then filtered water is used as a water intake source.

That is, "A" in FIG. 1 is a schematic perspective view showing a conventional simple tap water filtering device, "I" is a schematic longitudinal cross-sectional view of "A", and FIG. 2 is a view showing a state of use of a conventional simple tap water filtering device. Schematic longitudinal section view.

Referring to FIG. 1, the conventional simple tap water filtration device 10 includes a main body 20, an inlet pipe 60, an outlet pipe 70, and a washing water supply means 80.

First, the first filter chamber 30, the settling tank 40, and the second filter chamber 50, which are divided by the partition wall 22, are sequentially formed in the main body 20, and the first filter chamber 30 is formed. The inflow pipe 60 through which raw water flows is installed at the upper portion of the silver, and is partitioned by a perforated plate 32, and the upper filter layer 34 for filtering foreign substances such as various sludges contained in the raw water is predetermined. It is laminated at the height of. In addition, the settling tank 40 is communicated with the lower portion of the first filtering room 30 through the communication hole 42, the space in which the fine foreign matter contained in the filtered water filtered through the first filtering room 30 is immersed To provide. In addition, the second filtration chamber 50 is in communication with the settling tank 40 through the transfer pipe 56 provided on the upper portion, the inside is divided into a porous plate 52, the upper portion of the various contained in the filtered water The filter medium layer 54 for filtering foreign substances such as sludge once again is stacked at a predetermined height, and a discharge pipe 70 for discharging the filtered filtrate to the outside is connected to the lower portion. And, it can be seen that the overflow pipe 58 is provided on the upper rear side of the first and second filtering chambers 30 and 50, respectively.

Next, the inlet pipe 60 is connected to the washing water supply means 80 to remove sludge accumulated in the filter media layers 34 and 54 provided in the first and second filtration chambers 30 and 50. Backflow for being connected to the inlet pipe 60 and connected to the washing water supply pipe 82 and lowering the main body 20 and the washing water supply pipe 82 to supply the washing water to the first and second filtration chambers 30 and 50. It comprises a tube (84,86).

Of course, the inlet pipe 60 and the backflow pipe (84,86) is further provided with an intermittent valve (62, 88, 89) to control the flow of the wash water.

Now, with reference to Figure 2, it will be described the operation of the conventional simple tap water filtration device 10 configured as described above.

First, here, the intermittent valves 88 and 89 provided in the counter flow pipes 84 and 86 of the washing water supply unit 80 are not shown, and are locked to prevent the valley water from flowing into the counter flow pipes 84 and 86. The intermittent valve 62 provided in the inlet pipe 60 is in an open state.

In this state, the valley water introduced into the inlet pipe 60 is introduced into the first filtration chamber 30 and passes through the filter bed layer 34 to be introduced into the settling tank 40 through the communication hole 42. The filtered water introduced into the 40 is introduced into the second filtering chamber 50 through the transfer pipe 56 provided at the upper portion, and the introduced filtered water passes through the filter layer 54 provided in the second filtering chamber 50. Once again passed through and is finally discharged to the outside through the discharge pipe 70 provided in the lower portion.

Therefore, the conventional simple tap water filtration apparatus 10 filters and discharges the valley water introduced by the above operation, but the filter medium layer 54 provided in the second filter chamber 50 is transferred through the transfer pipe 56. It can be seen that the passage is formed by being split by the filtered water. That is, the filtered water flowing into the second filter chamber 50 is immediately discharged to the outside through the discharge pipe 70 provided in the lower portion will not maintain the proper level in the second filter chamber 50 itself, thereby Layer 54 will be dry. Therefore, when the filtered water is discharged through the transfer pipe 56 for a long time in the filter medium layer 54 which is kept dry, it is not surprising that a passage through which the filtered water passes is formed at the point where the filtered water falls. Filtered water discharged after the passage is formed in the filter medium is not filtered by the filter layer 54 of the second filter chamber 50, and thus the filter layer layer 54 of the second filter chamber 50 has no function. To have.

Therefore, the conventional simple tap water filtration device 10 is a situation that has a disadvantage in that the filtration function for the incoming valley water is reduced.

In addition, although not shown, it will be described schematically the operation of the washing water supply means (80). If the above operation is performed for a long time, the sludge layers 34 and 54 of the first and second filtration chambers 30 and 50 will contain various sludges and foreign substances. Then, in order to remove this, first, the intermittent valve 62 provided in the inlet pipe 60 is closed and the intermittent valves 88 and 89 provided in the backflow pipes 84 and 86 are opened. Then, the valley water will flow into the first and second filtration chambers 30 and 50 through the backflow pipes 84 and 86, respectively, and as a result, various foreign substances contained in the media layers 34 and 54 will be increased. It floats and is discharged to the overflow pipe 36 and 58 provided in the upper side.

On the other hand, in the above washing process, it is too natural that the various foreign matters that float in the first filtering room 30 to be introduced into the settling tank 40 through the communication hole 42 provided on the lower side, so as to the settling tank 40 The introduced foreign matter will flow into the second filter room 50 unless it is settled in the settling tank 40. If the filter layer 54 of the second filter room 50 is divided as described above, it is natural that they are included in the filtered water discharged through the discharge pipe 70. Even has a problem that can hurt.

Therefore, in recent years, there is an urgent need for improvement of the problems of the conventional simple tap water filtration device 10.

The present invention has been made in order to solve the above problems, it is excellent in filtration function can not only supply a clean intake source, but also very easy to maintain and maintain the cleaning, discharge the filtered water stably discharges the filtered water stably.

And, the settling tank 130 is provided on one side of the first filtration chamber 120, the first transport pipe 132 is provided on the lower outer side, the intermittent valve 134 is intermittent to intercept the water flow; Through each other. That is, the filtered water filtered through the filter medium layer 124 provided in the first filter chamber 120 is transferred to the settling tank 130 through the first transfer pipe 132. Here, the first transfer pipe 132 is not provided inside the main body 110, but is provided outside, so that the user, if necessary, that the filtration water of the first filtering chamber 120 is transferred to the settling tank 130 It is so natural to be able to crack down.

In addition, the second filtering chamber 140 is provided on one side of the settling tank 130 and communicated with each other through the second transfer pipe 146 provided on the upper side, the inside is transversely by the porous plate 122 ' The upper portion is provided with a filter medium layer 144 for filtering foreign substances such as various sludge contained in the raw water, and the discharge pipe 160 for discharging the filtered water is connected to the lower one side. At this time, it is preferable that the filter medium layer 144 provided in the second filter chamber 140 is made of sand having a relatively small particle size, which is finally filtered again before discharging the filtrate.

And, the upper side of the rear of the first and second filtering chambers (120, 140) is provided with overflow pipes (126, 148) to prevent the overflow of the valley water or the filtered water.

Next, the inlet pipe 150 is coupled to the upper portion of the first filter chamber 120 of the main body 110 is a pipe for supplying raw water, that is, valley water to the first filter chamber 120, a predetermined length is extended. Will be introduced to the valley water, is provided with an intermittent valve 152 that can control the inflow.

Next, the discharge pipe 160 is coupled to the lower side of the second filter chamber 140 of the main body 110 is provided to discharge the filtered filtration water to the outside, the control valve 162 is provided, the shape of the Unlike the prior art, the center portion is bent upward. That is, it can be seen that the bent center portion of the discharge pipe 160 is formed higher than the lowest portion of the filter layer 144 of the second filter chamber 140. The operation relationship thereof will be described later, but by bending the center portion of the discharge pipe 160 upward, the water level inside the second filter chamber 140 can be maintained at all times up to the height of the center portion, which is the bending portion of the minimum discharge pipe 160. Thus, the lower portion of the filter medium layer 144 provided in the second filter chamber 140 is not implemented to be dry. In addition, the upper portion of the center of the discharge pipe 160 is interposed with an air injection valve 170 is automatically injected with air in accordance with the internal pressure of the discharge pipe 160 to facilitate the flow of filtered water, the configuration and The operating relationship will be described in more detail below.

Next, the lower side of the main body 110 has a washing water supply means 80 to reverse the water to remove various sludge or foreign matter accumulated in the filter medium layer (124,144) provided in the first and second filter chambers (120,140) Is provided, the washing water supply means 80 is connected to the inlet pipe 150 through which the raw water is introduced as in the prior art is connected to the washing water supply pipe 82 and the washing water supply pipe 82 extending to the lower side of the main body 110 It is composed of a back flow pipe (84,86) is provided with an intermittent valve (88,89) for supplying the raw water to the lower side of the first and second filter chambers (120,140) to regulate the flow of raw water. Since the washing water supply means 80 is the same as in the related art, it has been schematically described, and the same reference numerals are used.

"A" of Figure 5 is a perspective view of the discharge pipe according to an embodiment of the present invention, "I" is a perspective view showing another shape of the discharge pipe according to an embodiment of the present invention, "A" of FIG. And "b" are enlarged cross-sectional views of portion A of FIG. 5 showing the configuration and operation of the air injection valve.

First, referring to “a” of FIG. 5, the discharge pipe 160 of the present invention has an approximately omega shape in which a center portion is bent upward as described above. Of course, this center portion should be formed at least higher than the lowest end of the filter layer 144 provided in the second filter chamber (140). And, the center portion is equipped with an air injection valve 170 for automatically injecting air in accordance with the pressure inside the discharge pipe 160, the configuration thereof will be described in detail below.

Subsequently, referring to "b", it can be seen that the discharge pipe 160 has a stepped shape in which the end portion thereof is bent upward rather than the middle portion thereof bent upward as described above.

Therefore, the discharge pipe 160 of the present invention may have a variety of shapes, but may have any shape, but any one of the discharge pipe 160 is bent to the lowest end of the filter medium layer 144 provided in the second filter chamber 140 It should be noted that it is formed higher than the part.

Now, the configuration and operation relationship of the air injection valve 170 will be described with reference to FIG. 6.

First, referring to "a", the air injection valve 170 of the present invention is coupled to the upper side of the discharge pipe 160, the case 172 is opened up and down so that the air can communicate with the case 172 Including an operating plate 174 that is rotatably coupled via a hinge (h) in the inside and a packing 176 provided in the upper portion of the case 172, the upper surface of the operating plate 174 to be rotated in contact with The air injection valve 170 configured as described above is automatically operated according to the filtered water introduced into the discharge pipe 160. That is, when the amount of filtrate in the discharge pipe 160 increases as shown in the "a", the operating plate 174 is in close contact with the packing 176 provided on the upper side by the pressure to block the inner diameter of the case 172. By blocking the inflow of the air, on the contrary, as shown in the "I", as the amount of filtered water in the discharge pipe 160 is reduced, since the pressure is lowered, the operating plate 174 will be automatically rotated downward, thereby causing the air to It will be introduced into the discharge pipe 160 in the direction of the arrow to facilitate the flow of filtered water.

At this time, the radius of the downward rotation of the operating plate 174 needs to be limited. That is, even when the operating plate 174 is in close contact with the packing 176 and is rotated downward by pressure in a state of blocking the inner diameter of the case 172, only as much as air can flow into the inner diameter of the case 172, that is, 30 degrees. It is desirable to limit the turning radius within to facilitate the re-closing operation.

7 is a perspective view of a porous plate according to a preferred embodiment of the present invention, and "b" is an enlarged sectional view taken along line A-A of "ga".

First, referring to "a", the porous plates 122 and 122 'have a strainer 123 having a pore 123a to prevent clogging caused by various media or sludge or foreign substances. Is mounted. That is, since the conventional porous plate 32 is formed with a plurality of planar holes in the plane, the phenomenon is often blocked by the filter medium provided on the upper portion, in the present invention, the strainer protruding upward on the porous plate 122 The above-mentioned conventional problem is overcome by mounting 123.

Therefore, as shown in "I", the filtered water will be smoothly communicated to the pores 123a formed in the strainer 123 protruding upward of the porous plate 122.

Now, the filtration operation of the simple tap water filtration device 10 of the present invention configured as described above will be described.

8 is a schematic view showing a state of use of the simple tap water filtration device of the present invention.

First, "a" is a longitudinal cross-sectional view schematically showing the simple tap water filtration device 10 of the present invention, first of all, an intermittent valve provided in the backflow pipes 84 and 86 of the washing water supply means 80 not shown. 88 and 89 are locked to prevent the inflow of the valley water into the backflow pipes 84 and 86, and the intermittent valves 152, 134 and 162 provided in the inlet pipe 150, the first transfer pipe 132 and the discharge pipe 160. Is open. In this state, the valley water introduced into the inlet pipe 150 is introduced into the first filter chamber 120 and filtered by the filter layer 124 and then stored under the porous plate 122.

Now, as shown in the schematic plan view of "I", the filtered water filtered by the filter media layer 124 of the first filter chamber 120 is passed through the first transfer pipe 132 provided outside the main body 110 Sea is introduced into the settling tank 130.

Subsequently, as shown in the schematic longitudinal sectional view of "C", the filtered water introduced into the settling tank 130 is introduced into the second filtration chamber 140 through the second transfer pipe 146 provided on the upper side. At this time, it is natural that the various sludge contained in the filtered water introduced into the settling tank 130 to be partially immersed in the bottom surface of the settling tank 130 before being introduced into the second filter 140.

Thus, the filtered water introduced into the second filter chamber 140 is filtered once again by the filter layer 144 provided therein and then discharged to the outside through the discharge pipe 160. On the other hand, since the center portion of the discharge pipe 160 is bent upward and formed higher than the lowermost portion of the filter layer 144 of the second filter chamber 140, the water level inside the second filter chamber 140 is always one dashed line. It will not be lower than the water level line B shown. Therefore, since the water level is maintained in the interior of the second filter chamber 140 so that the lower end of the filter layer 144 is always submerged in water, the filter layer 144 may not dry out. It is possible to prevent the formation of passages due to drying.

As a result, the filter layer 144 provided in the second filter chamber 140 is not dried and is not separated by the filtered water to be introduced, so that the filtering function can be properly exhibited, thereby providing a cleaner intake source. In addition, the discharge pipe 160 is equipped with an air injection valve 170, so that the flow of filtered water discharged can be more smoothly.

On the other hand, although not shown here will be briefly described for the washing operation of the simplified tap water filtration device 100 of the present invention.

First, the intermittent valves 152, 134, and 162 of the inlet pipe 150, the first transfer pipe 132, and the discharge pipe 160 are locked, respectively, and the intermittent valves 88 of the backflow pipes 84 and 86 connected to the wash water supply pipe 82 are respectively closed. 89 will be opened respectively. Then, as in the prior art, the raw water flowing into the inlet pipe 150 does not flow into the first filtering chamber 120, but each of the backflow pipes connected to the lower side of the first and second filtering chambers 120 and 140 along the washing water supply pipe 82. The sludge and foreign substances accumulated in the media layers 124 and 144 of each chamber are floated while being flowed back into the interior through 84 and 86 to be discharged to the overflow pipes 126 and 148 formed on the upper side.

In the washing process, since the first transfer pipe 132 communicating with the first filter chamber 120 and the settling tank 130 is provided outside the main body 110, unlike the conventional method, the flow of filtered water can be easily interrupted. Foreign matters generated during washing can be prevented from entering the settling tank 130, which has the advantage of easy maintenance such as cleaning.

Therefore, according to the simple tap water filtration apparatus 100 of the present invention, since a portion of the discharge pipe 160 is formed higher than the lowermost portion of the filter layer 144 provided in the second filter chamber 140, the second filter chamber ( The lower level of the filter medium layer 144 may be maintained at an appropriate level in which water can be constantly placed in the water, thereby preventing the drying of the filter medium layer 144, thereby improving the filtering function of the filter medium layer 144, thereby providing a cleaner water source. There is an advantage that can supply.

In addition, since the first transfer pipe 132 communicating with the first filtering chamber 120 and the settling tank 130 is provided outside the main body 110, it is possible to easily control the flow of water, so it is easier for maintenance such as cleaning. It has one advantage.

The foregoing has outlined rather broadly the features and technical advantages of the present invention in order to better understand the claims of the invention which will be described later.
