If the raw water is supplied to the) is positioned horizontally by the stopper 126. At this time, the raw water is supplied into the secondary filtration tank 130 through the gap G of the secondary overflow pipe 123.

An overflow float discharge pipe 140 is installed inside the primary filtration tank 120 to discharge the suspended matter suspended in the primary filtration tank 120 to the outside of the primary filtration tank 20 during the back washing. In the overflow floating discharge pipe 140, the overflow discharge pipe opening and closing unit 150 for opening the overflow discharge pipe 140 when the water level of the primary filtration tank 120 rises at the time of back washing is provided.

In the non-powered village liver abnormal water filtration apparatus 100 capable of automatic backwashing according to the present invention configured as described above, at the time of normal filtration, the raw water of the temporary storage tank 110 passes through the primary overflow pipe 121 through the primary water. It is introduced into the filtration tank 120 and passed through the downward filtration, and introduced into the secondary filtration tank 130 and discharged through the filtration water outlet pipe 131 through the upward filtration.

On the other hand, in the case of backwashing when the surface of the filter medium in the primary filtration tank 120 is dense and the water level in the primary filtration tank 120 is increased, the primary overflow pipe bulging ball 122 is subjected to buoyancy. It operates by blocking the primary overflow pipe 121, the raw water of the temporary storage tank 110 is supplied into the secondary filtration tank 130 through the secondary overflow pipe 123, the secondary The raw water of the filtration tank 130 is introduced into the primary filtration tank 120 through the downward filtration and the upward filtration of the primary filtration tank 120, the suspended matter in the primary filtration tank 120 is buoyancy By the operation of the overflow discharge pipe opening and closing unit 150 operated by the overflow through the overflow float discharge pipe 140 is discharged to the outside of the primary filtration tank 120.

On the other hand, in the automatic reverse washing method of the present invention, during normal filtration, the raw water of the temporary storage tank 110 is introduced into the primary filtration tank 120 through the primary overflow pipe 121 and filtered downward, and the secondary filtration tank. In the rapid filtration method which flows into the 130 and is filtered upwardly and discharged through the filtration water outlet pipe 131, the surface layer of the filter medium (F1) in the primary filtration tank 120 is dense due to water pollution, so that the primary filtration When the water level in the tank 120 is increased, the primary overflow pipe opening and closing ball 122 is operated by buoyancy to block the primary overflow pipe 121 at the time of reverse washing, and the temporary storage tank 110 ) Raw water is supplied into the secondary filtration tank 130 through the secondary overflow pipe 123, the raw water of the secondary filtration tank 130 undergoes downward filtration and upward filtration of the primary filtration tank 120 Flows back into the primary filtration tank 120 via a suspension in the primary filtration tank 120. Is by the operation of the overflow discharge opening and closing unit 150 to be activated on the buoyancy through the overflow discharge pipe suspended 140 discharged from the primary filtration tank 120.

Hereinafter, with reference to the accompanying drawings will be described in more detail the operation of the non-powered village liver abnormal water filtration apparatus capable of automatic backwashing according to the present invention.

Raw water (valley water) is continuously introduced into the temporary storage tank 110, the unfiltered water of the temporary storage tank 110 at the time of normal filtration, raw water is the primary filtration tank (through the primary overflow pipe 121) 120) flows into. At this time, since the secondary overflow pipe 123 is positioned relatively higher than the primary overflow pipe 121, raw water flows only into the primary overflow pipe 121 during normal filtration.

Raw water introduced into the primary filtration tank 120 is filtered downward through the filter medium (F1) and strainer (S), and introduced into the secondary filtration tank (130) through the strainer (S) and filter medium (F2) After the upward filtration is discharged to the outside of the tank through the filtered water outlet pipe (131). At this time, the on-off valve 125 closes the secondary flow pipe 123 by the torsion spring 126, and the filtered water outlet pipe 131 is kept open.

When a lot of rain falls during the rainy season, fallen leaves or suspended matter may be introduced into the temporary storage tank 110 with the raw water. In this case, primarily the deciduous or suspended matter is filtered by the high turbidity filter 164 installed under the temporary storage tank 110, and the raw water from which the deciduous or suspended matter is filtered is passed through the primary overflow pipe 121. It is introduced into the primary storage tank 120. Here, the high turbidity filter 164 can be visually confirmed from the outside of the temporary storage tank 110 through the see-through window 165, and if a replacement is necessary, loosen the bolt (B) to separate the see-through window 165, The high turbidity filter 164 may be removed, and the new high turbidity filter 164 may be guided and fixed to the guide rail 166 again.

When the turbidity of the raw water introduced into the primary storage tank 120 gradually increases, the surface of the filter medium F1 gradually becomes dense, and the raw water level in the primary filter tank 120 rises rapidly. The back washing proceeds from the moment when the water level of the primary filtration tank 120 rises. First, when the water level of the primary filtration tank 120 rises, the buccal ball 122 of the primary overflow pipe 121 is buoyant. It rises by blocking the primary overflow pipe 121. At this time, the raw water of the temporary storage tank 110 does not flow into the primary overflow pipe 121, but flows into the secondary overflow pipe 123.

 The raw water introduced into the secondary overflow pipe 123 overcomes the elastic force of the torsion spring 126 and pushes the on / off valve 125 and is continuously introduced into the secondary filtration tank 130. When the water level of the secondary filtration tank 130 rises, the suspended matter in the surface layer of the filter medium F2 floats, and when the water level reaches the proper position, the overflow discharge opening / closing ball 153 rises to hinge the blocking membrane 151 ( H) is rotated about the opening, and the float of the secondary filtration tank 130 is first discharged out of the secondary filtration tank 130 through the overflow discharge pipe 140.

Raw water (non-filtered water) continuously introduced into the secondary filtration tank 130 proceeds in the reverse order of the above-described normal filtration to raise the level of the primary filtration tank 120. At this time, the floating material of the surface layer of the filter medium (F1) is suspended, and when the water level reaches an appropriate position, the overflow discharge pipe opening and closing ball 183 rises to rotate the blocking film 181 about the hinge (H) to open. Secondly, the suspended matter in the secondary filtration tank 130 is discharged out of the secondary filtration tank 130 through the overflow discharge pipe 170.

The backwash is continued until the suspended solids of the filter medium F1 and the surface layer of the filter medium F2 are completely removed, and when the backwash is completed, the raw water of the primary filtration tank 120 flows into the secondary filtration tank 130. Therefore, the water level of the primary filtration tank 120 is lowered. At this time, the buccal ball 122 of the primary overflow pipe 121 returns to its original position and opens the primary overflow pipe 121. When the primary overflow pipe 121 is opened, the raw water of the temporary storage tank 110 is introduced into the primary filtration tank 120 through the primary overflow pipe 121, and the raw water introduced into the primary filtration tank 120 is Again, normal filtration through the secondary filtration tank 130.

As the normal filtration process proceeds as described above, when the quantity of valley water suddenly blows due to heavy rainfall or the like, and the turbidity of the raw water increases, the raw water inflow path of the primary overflow pipe 121 and the secondary overflow pipe 123 is switched. By automatically repeating the reverse cleaning process, the managers, workers, etc. working in the water purification plant or control center directly check whether the water level of the filter paper is operating normally, flow inflow and outflow, discharge, discharge, shoot, tax, etc. There is no need to check whether the valves and pumps that perform the functions are operating normally.

As described above, in the present invention, since the normal filtration process and the backwash process are both automatically performed, it is easy to control a series of processes, and there is an effect of reducing the cost by reducing the number of required workers.

As such, the rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications within the scope of the claims. It is self evident.
