Even if the filter bed surface is not uneven. Therefore, since the distance from the inflow port to the filter bed surface can be shortened, the size of the filtering device can be shortened and the liquid can be uniformly filtered. Moreover, since the liquid is dispersed and evenly poured onto the filter bed surface, the filtration flow rate becomes faster than the flow in which the liquid is collected in one place, and the filtration flow rate increases to improve the filtration efficiency.

FIG. 1 is a schematic sectional view of a filter device according to an embodiment of the present invention. In FIG. 1, reference numeral 1 is a filtering device body, which is a cylindrical container having a diameter of about 1 to 3 m. An inflow port 3 for the liquid 2 is formed on the upper part of the filtering device body 1 so as to project upward.
A conical main baffle 5 supported by a support portion 4 is attached just below the inflow port 3. Below the main baffle 5, a substantially semispherical sub baffle 6 that absorbs the fluid energy of the liquid 1 and disperses the flow of the liquid 1 is provided so as to surround the main baffle 5 from below. . This sub baffle 6
Is formed with 40 through holes 7 having a diameter of 9 mm so that the inflowing liquid 2 is dispersed and flows down. However, the diameter and number of the through holes 7 are not limited to such numerical values. A filter material 8 for filtering the liquid 2 is supported and filled in a lower portion of the sub baffle 6 by a support material 9. Below the supporting member 9, a perforated tube 11 having a large number of through holes 10 is horizontally provided. This perforated tube 1
One end of 1 projects from the filtering device main body 1 and flows out of the outlet 12
Has become. The flange 1 is attached to one end of the perforated pipe 11.
3 is formed and is configured to connect to a drainage pipe (not shown).

通って流出口１２から流出する。Next, the operation of the above embodiment will be described. The liquid 2 for filtering is pressurized and flows in through the inlet 3 of the filtering device. The liquid 2 that has flowed in first hits the main baffle 5 to absorb energy, and then flows downward. The liquid 2 that has flowed down flows into the sub-baffle 6 and then flows down from a large number of through holes 7. The energy of the liquid 2 is scraped by the sub-baffle 6, dispersed by the through holes 7, and poured onto the filter bed surface 14. The liquid 2 that has poured in the shape of a shower drops evenly onto the filter bed surface 14 and does not cause large irregularities on the filter bed surface 14.
The filtrate 15 that has passed through the filter medium 8 and is filtered passes through the perforated pipe 11 and flows out from the outlet 12.

Moreover, since the liquid 2 is dispersed and pours softly and evenly onto the filter bed surface 14, the filtration flow rate becomes faster and the filtration flow rate becomes larger than the case where the liquid 2 flows all together. Due to this improvement in filtration efficiency, the volume can be reduced as compared with the conventional filtration device if the flow rate of the liquid to be filtered is the same.
