PURPOSE:To constitute a strainer having a gas-liquid separating function, to which another function to discharge an excess of gas to the outside of a device by detecting the lowering of liquid level resulting from an increase of a separated gas phase is added. CONSTITUTION:When COM flows into the outside of a cylindrical filtering body 17 from a flow-in port 5 of a treating tank 4, coarse particles are captured by a filtering surface, and the COM containing a portion of small particles smaller than the regulated screen openings of the filtering surface passes through the surface to flow out of a discharging port 6. A gas phase portion contained in the COM is captured on the filtering surface to grow up to gas bubbles, and the gas bubbles are gathered by a scraper 18 sliding on the filtering surface and rise along the scraper 18 to be stored in a separated gas storing part 9 through holes of a buffle plate 8, and the liquid level is lowered with an increase of the stored gas, and accordingly, a float 11 is lowered which causes an opening of a gas exhausting port 10 to discharge the gas portion, and also that causes the rise of liquid level to close the port 10 by a valve 14. The coarse particles are discharged from a drain port 7 by a scraper 16. |
