In addition, the prior art has to replace the filter medium at regular intervals, it took a lot of time and effort to replace a large amount of stone. Therefore, in the case of using the conventional filtration device, considering the cost of water and filter medium replacement during backwashing required a huge maintenance cost.

In addition, in the conventional swimming pool water purification system, chlorine disinfection is mainly performed to remove bacteria contained in the water after the water filtering. In this case, chlorine reacts with organic substances in the water, causing the formation of 'trihalomethanes'. Substances may occur, and furthermore, when a user using the swimming pool enters a long time, there is a problem that a respiratory disorder may be caused by chlorine.

The foreign material removal filter and the vacuum pressure transfer tube 235 communicate with each other through a predetermined pipe 237, and the pipe 237 is provided with a valve 237a for blocking vacuum pressure.

3 to 6, the filter unit 250 includes a support plate 251, a filter member 253, and a coil spring 255. The support plate 251 is disposed horizontally with respect to the longitudinal direction of the filtration tank 210 and a plurality of holes 251a are formed. Each of the plurality of filter members 253 has a cylindrical shape, one end of which is open and the other end of which is closed, and a plurality of micro holes (not shown) are formed on the outer circumference thereof. One end of each of the plurality of filter members 253 is communicatively connected to the plurality of holes 251a of the support plate 251. Accordingly, the water introduced into the lower part of the filtration tank 210 through the water inlet pipe 218a is After being filtered while being introduced from the outside of the filter member 253, the filter member 253 is moved up to the upper part of the filtration tank 210 and then discharged to the outside of the filtration tank 210 through the water discharge pipe 218c. .

The coil spring 255 has a length approximately corresponding to the length of the filter member 253 and is inserted into the hollow portions 253a of the plurality of filter members 253, respectively.

The fixed shaft 271b fixed to 271a, and the support rod 271c which mutually support the fixed plate 271a and the fixed shaft 271b are included. The compressor 273 applies the impact to the filter unit 250 by instantaneously spraying compressed air to the inside of the inflow tank 210 to flow up and down the filter unit 250. In this case, the plurality of filter units 253 are shaken in an arbitrary direction by vibration to remove the coating material (C).

The shock absorbing part 275 is installed on the cover 213 of the filtration tank 210 to absorb the shocks received by the filter unit 250 and the movable part 271, and thus the filter unit 250 and the movable part 271 are damaged due to the accumulation of shock. Prevent it.

Such a filtering device 200 supplies the coating material (C) for filtering periodically without the need to replace the filter unit 250 and removes the pre-coated coating material (C) from the filter member 253 through backwashing. Can be used semi-permanently. In addition, when backwashing the filter unit 250, the coating material and the foreign matter attached to the filter unit 250 through the impact by the compressed air supplied from the compressor 273 is peeled together from the surface of the filter member 253 to filter the filter ( It is mixed with the water charged in the 210, and then backwashing the filter unit 250 is sufficiently made by discharging the water inside the filtration tank 210 through the drain pipe 215. In this case, when the present invention is used at the same scale as that of the swimming pool to which the prior art is applied, the water used for backwashing the filter unit 250 corresponds to the amount of water charged into the filtration tank 210, that is, approximately 600L.

The ozone generator 31 is in communication with the pipe 32b by the ozone supply pipe 34 so as to include ozone in the water transported along the pipe 32b by the pump 32a. In this case, when the ozone generator 35 stops operation due to a failure or maintenance due to a predetermined valve 32c installed in the pipe 32b, the filtered water does not directly pass through the pipe 32b. It is supplied to the swimming pool 1 via the mixing part 33 and the ozone reaction tank 35.

The ozone mixing unit 33 is a pretreatment device for mixing the water flowing in the state that is not completely mixed with ozone supplied from the ozone generating unit 31 with ozone to increase the reaction efficiency in the ozone reaction tank 35.

Water discharged from the collecting device 11 is introduced into the filtration device 200, in which case, the water introduced into the lower portion of the filtration tank 210 is moved from the outside to the inside of the plurality of filter members 253 of the filter unit 250. To pass. At this time, the water passes through the coating material (C) pre-coated on the outer circumference of the filter member 253 and then moves to the upper side of the filtration tank 210, but the foreign matter contained in the water does not pass through the coating material (C) filter member 253 As it is attached to the outer periphery of), it is separated from the water.

Water flowing into the filtration tank 210 is introduced into the ozone treatment unit 30 along the water discharge pipe 218a. Water filtered while passing through the filtration device 200 moves toward the ozone mixing unit 33 along the pipe 32b by the pump 32a. At this time, the water flows into the ozone mixing unit 33 together with the ozone generated in the ozone generating unit 31, and then is mixed with ozone in the ozone mixing unit 33. The water mixed with ozone is introduced into the ozone reaction tank 35 to be sterilized and discharged from the ozone reaction tank 35 in a state where ozone is removed from the water sterilized by the ozone removal unit 37.

The water discharged from the ozone reactor 35 is supplied to the swimming pool 1 through a plurality of nozzles 2 arranged at the bottom of the swimming pool 1.

In this case, in the present embodiment, in addition to the sterilization treatment by ozone, a predetermined number of chemical supplies 41a, 41b, 41c controlled by the controller 50 in accordance with the water quality of the water detected by the water quality detection sensor 43 are prescribed. It is also possible to include drugs. As such, in the present invention, the ozone treatment unit 30 and the chemical treatment unit 40 are provided together, thereby increasing the ratio of water disinfection through the ozone treatment unit 30 to relatively disinfect the dependency on the chemical treatment unit 40. As it can be lowered, the disinfected water can minimize the damage such as skin diseases caused to the swimming pool users.

As described above, the purification system according to an embodiment of the present invention can circulate the pool water in a state of continuously maintaining a high purification quality.

In addition, the present invention, when backwashing the filter unit 250 of the filtration device 200, after the impact on the filter unit 250 through the compressor 273 to precipitate the foreign matter separated from the filter member to the lower side of the filtration tank 210 By discharging the water charged into the filtration tank 210 through the drain pipe 215, the back washing can be performed quickly and easily, as well as the amount of water used for the back washing of the filter unit 250 is significantly higher than in the related art.
