PROBLEM TO BE SOLVED: To enable to separate even such small dust particles that pass through a front filter of a conventional liquid transportation device from liquid. SOLUTION: A central room 16 connected with the outlet, and at least one of a circular arc shaped fludizing path 17, 18 connected with at least one of inlets 12, 13 and bent in a recess face toward the central room 16, are formed in a casing 11 having at least one of the inlets 12, 13 for liquid and one outlet. Connection openings 21, 22 to the central room are provided on inside path walls 172, 182 of the fludizing path 17, 18. A normal line of connection openings 21, 22 faces nearly in the radius direction against an ordinate line of the fludizing path 17, 18. |
