Power to rotate (320) can be generated, and for ease of rotation, the nozzle (330) is installed to have an inclination in the opposite direction to the direction to be rotated, so that the pressure of the washing water discharged through the nozzle (330) can be adjusted to This is to obtain driving force so that the rotary tube 320 can obtain power to rotate.

In addition, in the present invention, the discharge pressure of the treated water for rotating the rotary tube 320 is controlled by a controller to have different discharge pressures depending on the weight or length of the rotary tube 320, and for this purpose, the controller The pump (P) controlled by can be driven by a servomotor.

Furthermore, the nozzle 330 in the present invention is sprayed to have a spray nozzle angle of 40° to 45° to clean the filter membrane 210 or the inner wall of the housing 100, thereby cleaning the filter membrane 210 or the housing 100. ) It is possible to spray treated water evenly over the entire inner wall.

As described above, the backwash member 300 is operated according to a time set by the operator through the timer 51 provided in the controller 50.

For example, as shown, when the set time for the backwash member 300 to operate is reached through a timer, the controller 50 'closes' the water intake pipe 110 and the water outlet pipe 120 using a valve (not shown). In the controlled state, at least one of the drain pipe 130 and the washing water discharge pipe 140 is controlled to the 'open' state so that all the water present inside the housing 100 can be discharged through the drain pipe 130. make it possible

In this state, the controller 50 opens the supply pipe 310 to allow the inflow of washing water, and the washing water flowing in from the rainwater storage tank 500 through the supply pipe 310 flows into the rotary pipe 320 through the discharge pressure of the pump (P). ) and at the same time is sprayed through a plurality of nozzles 330 to remove foreign substances present on the inner wall of the housing 100 and the filter membrane 210 for a set time.

Here, the washing water mixed with foreign substances is controlled in an 'open' state by the controller 50 so that it can be drained to the outside through the outlet side of the drain pipe 130 connected to the washing water discharge pipe 140.

Finally, when the cleaning of the housing 100 and the filter 200 is completed for a set time and the washing water mixed with foreign substances is drained through the washing water discharge pipe 140, the controller 50 operates the washing water discharge pipe 140 and the drain pipe. (130) and the supply pipe 310 are controlled in the 'closed' state, and the water intake pipe 110 and the water outlet pipe 120 are controlled in the 'open' state so that the supply water flows into the housing 100 and is filtered, Allow water to be discharged to the outside.

Meanwhile, the operation of the backwash member 300 in the present invention may be determined by the controller 50 that receives a measurement value from at least one of the above-described differential pressure sensor or the concentration measurement sensor installed in the water outlet pipe 120.

That is, if it is determined that the filtering effect of the filter 200 has deteriorated based on the measured value of the differential pressure sensor or concentration measurement sensor while the set time through the timer 51 has not been reached, the controller 50 uses the timer 51 ), the backwash member 300 can be operated regardless of the time set in ).

In another embodiment, as shown in FIGS. 10 and 11, the filtration tank in the present invention includes maintenance means for lifting the backwash member 300 together with the heavy chain cover 180 for maintenance purposes. 600 may be further provided, and the maintenance means 600 includes a support body 610 and a screw 620.

As shown, the support body 610 is formed in the form of a bar with a predetermined height and a length in the vertical direction. The lower part is fixed to the outer surface of the housing 100, and the upper part is screwed to the outer surface of the screw 620. A screw hole 611 is formed.

At this time, the position of the screw hole 611 is located directly above the supply pipe 310, so that through rotation of the screw 620, the cover 180 and the backwash member 300 are moved together in the rotation direction of the screw 620. Accordingly, it is desirable to satisfy the structure of raising and lowering the housing 100 so that it can enter and exit the housing 100.

The lower part of the screw 620 screwed into the screw hole 611 is rotatably coupled to the backwashing member 300, and a handle 621 is formed at the upper part to enable rotation through the operator's manual operation.

Here, the backwash member 300 rotatably coupled to the screw 620 is prevented from interfering with the supply pipe 310 connected to the rainwater storage tank 500 through the 'T' pipe, as shown.

Therefore, as shown in FIG. 11, when executing replacement of the filter 200 or maintenance of the backwash member 300, the operator turns the handle 621 to raise the screw 620 to lift the cover 180. As the backwash member 300 connected to ) rises together, it becomes easy to replace the filter 200 or repair the backwash member 300 from the outside.

In addition, in the present invention, the rotation of the screw 620 through the handle 621 is explained as an example, but it is not limited to this, and an automatic rotation structure is also possible under the control of a controller using a motor, etc., if necessary.

And, as shown in FIGS. 1 and 2, the rainwater storage tank 500 stores the treated water filtered by the filter 200 of the filtration tank described above, and at the same time, wash water required for cleaning the backwash member 300. It is configured to supply and includes a pump (P).

For this purpose, the pump (P) controlled through the controller has one end connected to the inside of the rainwater storage tank 500 and the other end connected to the supply pipe 310 to clean the inner wall of the housing 100 or the filter membrane 210. It has a structure in which the treated water can be discharged through the nozzle 330 to have a predetermined discharge pressure.

In addition, the rainwater storage tank 500 in the present invention is described as being used to supply washing water to the backwash member 300, but this is only one embodiment, and other uses that require treated water as needed (e.g. Please note that it is also possible to supply it for use as a building purification facility, etc.

Meanwhile, the rainwater storage tank 500 in the present invention may include a buoyancy valve in the rainwater discharge portion to prevent water overflow of the rainwater storage tank 500 when the inflow blocking valve does not operate due to a failure or the like.

As described above, the filtration device 1 according to the present invention is different from the conventional one in that the supply water flowing into the housing 100 through the water intake pipe 110 is filtered by the filter 200, A plurality of nozzles 330 that can be discharged as treated water through (120) and supply the washing water while the inside of the housing 100 is empty according to the time set through the controller 50 and at the same time spray the washing water. Through the discharge pressure, power to rotate the rotary tube is obtained without a separate motor, thereby realizing the effect of simultaneously or individually cleaning the inner wall of the housing 100 or the filter membrane 210.

As described above, the present invention has been described with specific details such as specific components and limited embodiments and drawings, but this is only provided to facilitate a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , those skilled in the art can make various modifications and variations from this description.
