- the circuit in which the second limit switch 315 is connected to a controller (not shown) forms a separate circuit separate from the circuit in which the first limit switch 314 is connected to a controller (not shown).
- the second limit switch 315 may be used.
- the second limit switch 315 transmits the contact signal to the control unit (not shown).
- the drive shaft 312 to which the contact means 313 is attached is to be controlled so as not to move any more.
- the second limit switch 315 is positioned to face the first limit switch 314, so that the second limit even when the separation distance between the first limit switch 314 and the second limit switch 315 is narrow.
- the switch 315 may allow the contact means 313 to be detected accurately. That is, if the second limit switch 315 is spaced up and down at the same position as the first limit switch 314, if the second limit switch 315 is not sufficiently spaced apart from the first limit switch 314, After the contact means 313 passes the first limit switch 314 and before the second limit switch 315 contacts, the interference between the first limit switch 314 and the second limit switch 315 already occurs.

- the suction rods 321 which are radially attached to the core 322 at a predetermined interval are interlocked according to the rotation and the shank of the core 322 to remove foreign substances attached to the inner circumferential surface of the filter 20.
- the lead length L2 at which the suction rod 321 moves upward while being rotated once is an inlet at which the foreign substance is sucked from the suction rod 321.
- the suction rod 321 is rotated by the length of the lead length L2 which is moved upward while the suction rod 321 is sucked by subtracting the length of the suction port diameter L1.
- the foreign matter attached to the inner circumferential surface of the filter is not sucked and still remains, and the suction surface of the filter 20 sucked by the suction rod 321 does not overlap while the suction rod 321 moves one lead.
- suction surface of filter 20 where suction rod 321 passed Due to the filtration process the filtration process continues without interruption during the backwashing process
- the foreign matter is attached again, so that the foreign matter remaining when the suction rod 321 is rotated downward in the future (these foreign substances are sucked in the suction rod) (321) will continue to attach more during the inhalation process, so that the adhesion thickness of the foreign matter becomes large) and the newly attached foreign matter hit the suction rod 321, so if the process is repeated repeatedly It causes a problem that the damage or damage of the rod 321 is more likely to occur, and the filtration efficiency is lowered due to the foreign matter attached to the filter.
- the lead length for moving the diameter L1 of the suction port 3211 in the suction rod 321 upward while the suction rod 321 rotates once By forming approximately equal to or larger than L2), the lead length L2 of which the suction rod 321 moves upward while making one rotation in the process of operating the automatic washing unit 30 to remove foreign substances in the filter 20 is performed. Since the suction rod 321 forms an interval equal to or smaller than the diameter L1 of the suction port 3211, which is an inlet for the foreign substance to be sucked in, the suction rod 321 moves while rotating one rotation upwards. The suction rod 321 is sucked when the diameter L1 of the suction port 3211 is formed larger than the lead length L2.
- the suction surface of the filter 20 is superimposed so that the suction surface of the filter 20 does not have backwashing on the inner circumferential surface of the filter 20. If there is no part present in the state attached to the material or is superimposed suction, thus, when the suction rod 321 is lowered while rotating downward in the future, the suction rod 321 collides with the foreign matter remaining as in the prior art Since it is also prevented in advance, in the process of backwashing the filter 20 in each filtration unit, the suction rod 321 for sucking the foreign matter can be prevented from being damaged or damaged by frequent collisions with the foreign matter, the filter It is possible to minimize the adhesion of foreign substances to the filtration efficiency is increased.
- the distance (L4) between the plurality of suction rods 321 connected to the core 322 is equal to or greater than the shankdong interval (L5) of the core 322

- the distance L4 between the plurality of suction rods 321 connected to the core 322 as compared to the shankdong spacing L5 of the core 322 By forming the same or smaller, the core 322 is upward While moving, the predetermined area of the filter 20 backwashed between the suction bar 321 and the suction bar 321 is overlapped so that foreign matter does not leave a portion of the filter 20 that is not backwashed, and thus, the core 322 in the future.
- suction rod 321 collides with the foreign substance remaining in the case of moving to the lower side, it is also prevented in advance to suck the foreign substance in the process of backwashing the filter 20 in each filtration unit. 321 may be prevented from being damaged or damaged due to frequent collisions with the foreign matter remaining, and the problem of inferior filtration efficiency.

- the pressure at the inlet is increased compared to the pressure)
- this method is applied to the plurality of filtration units in the body 10.
- the second pressure sensor is installed for each of the plurality of filtration units disposed in the body 10 of the filtration device to measure the pressure inside the filter 20 of each filtration unit ( 50), the first pressure sensor 40 for measuring the pressure inside the post-filtration chamber 162 just before discharge after the filtration process is completed, the post-filtration chamber 162 in the upper surface 130 of the body 10 in the figure
- An example of measuring the internal pressure is shown, but the pressure measured by the outlet portion 120 of the body 10 may be measured, and the filter of each filtration unit measured by the second pressure sensor ( 20) Since the internal pressure is individually prepared, the foreign material backwashing operation is automatically performed by the automatic washing unit 30 only for the filtration unit whose differential pressure exceeds a predetermined range, so that the suction of the discharge pipe 331 is carried out at once.
- Backwash water or foreign objects It can be prevented, and accordingly the flow rate is increased at once in the channel of the discharge pipe 331, or closed it is possible to solve the problem of back pressure increase. That is, assuming that four filtration units are arranged in one body 10 in the present invention, the back washing operation by the automatic washing unit 30 proceeds simultaneously in four filtration units in a conventional manner.
- the discharge pipe 331 When the discharge pipe 331 is discharged, movement of concentrated backwash water and foreign matters is concentrated in the pipe of the discharge pipe 331, and thus, the pipe of the discharge pipe 331 is frequently blocked (that is, the back pressure is excessively increased.
- the backwash water and the pipes of the discharge pipe 331 at once Foreign matters are not concentrated, but the backwash water and foreign matters, which are moved from each filtration unit, are dispersed and introduced into the pipeline of the discharge pipe 331, so that the pipeline of the discharge pipe 331 is blocked at once. And the back pressure is instantly increased to thereby prevent the phenomenon that the back washing operation can smoothly be made can be effectively prevented.
- the second pressure sensor 50 penetrates the upper cover plate 170 which blocks the upper portion of the body 10, that is, the filter inlet hole 131 of the upper surface 130. Since the pressure inside the filter 20 is measured through the measuring hole 173, repair and replacement of the second pressure sensor 50 may be performed even by dismantling only the upper cover plate 170. It can be done.
- the second pressure sensor 50 installed as described above directly penetrates the upper surface 130 of the body 10 to measure the pressure inside the post-filtration chamber 162 or at the outlet 120 of the body 10.
