In addition, the water is supplied through the inlet opening 83 formed in the central connecting pipe 74 of the back washing unit 70 through the central connecting pipe 74, the lower connecting pipe 72 and the upper connecting pipe 73. Water is also supplied to the filter opening 51 of the filter member 50 to which the backwashing unit 70 is coupled. The water supplied to all of the plurality of filter members 50 is filtered while passing through the filter hole 53 of the filter member 50 and is discharged to the outlet 37 through the outlet 35.
- the filter device 1 according to the present invention is supplied with water to both filter openings 51 of the filter member 50 through the lower inlet 14 and the upper inlet 15 during the filtration process, the lower inlet
- the filtration efficiency can be improved compared to the case where only (14) is formed.
- the partition member 55 is provided in the filter member 50, the water introduced from the lower inlet 14 and the water introduced from the upper inlet 15 are separated and filtered, respectively, so that the partition member 55 is provided.
- the filtration efficiency can be further improved compared to the case without.
- the partition member 55 by installing the partition member 55 at a position higher than the middle of the filter member 50, the filtration efficiency can be further improved in consideration of the influence of gravity.
- the filter device 1 has a foreign substance (a) through both filter openings 51 of the filter member 50 to the lower connection pipe 72 and the upper connection pipe 73 in the back washing process. Since the water is discharged, etc.), the back washing efficiency can be improved compared to the case where only the lower connection pipe 72 is formed.
- the partition member 55 is provided in the filter member 50, the water introduced from the lower inlet 14 and the water introduced from the upper inlet 15 are separated and filtered, respectively, so that the partition member 55 is provided.
- the backwashing efficiency can be further improved compared to the case without.
- the partition member 55 by installing the partition member 55 at a position higher than the middle of the filter member 50, the backwashing efficiency may be further improved in consideration of the influence of gravity.
- the filter device 1 by using the selection valve 81 in the case of performing only the filtration process without performing the backwash process, all the filter members 50 can perform the filtration process filtration efficiency Can be further improved.
- FIG. 9 is a schematic diagram of a filter apparatus according to another embodiment of the present invention.
- the filter device 100 is a connection pipe of the upper inlet part 15 and the inlet passage part 17 and the backwashing part 70 of the inlet part 13 in the above-described embodiment (
- the upper connecting pipe 73, the selector valve 81, the partition member 50, and the backwash valve 77 are added among the above-described embodiments. Except for this difference, it is the same as the above-described embodiment, and thus the description will be mainly focused on the difference.
- the backwash valve 77 is mounted to the discharge pipe 79 as an example of the present invention to open and close the discharge pipe 79.
