    • PROBLEM TO BE SOLVED: To provide a fluid transfer device which transfers a solid foreign matter such as screen residues removed from sewage with a fluid, and enables efficient discharge of the foreign matter such as the screen residues after being crushed.
      SOLUTION: Water containing screen residues is made to tangentially flow into a treatment water tank 10 by an inflow pipe 12 after being crushed by a crusher 16 installed on a guide chute 14. While the water containing the crushed screen residues is rotated in the treatment water tank 10 by an agitator 22 installed in the treatment water tank 10, the flow of the water is converted to a vertical flow by guide vanes 24, 26. A discharge pipe 36 opens at an intermediate position between a set water level L and the bottom 10-1 in the treatment water tank 10. The water containing the crushed screen residues is discharged by a drainage pump 38 to be transferred to a screen residue treatment site.

    • PROBLEM TO BE SOLVED: To provide a method of dealing with the elongation of a chain of a notched chain transmission device which does not require a preliminary fitting hole for a drive pin and helps simplify operating procedures.
      SOLUTION: The chain 8 is constituted of links 16 which make an endless and consecutive connection with each other by means of a connecting pin 18, and the bottom surface (a belly side) of the link 16 is notched 20. Further, a collar 30 on a drive pin 28 implanted, at an interval complying with a link pace in the circumference of a drive wheel 4, becomes engaged with the notch 20, on a drive wheel. Consequently, the transmission of power from the drive wheel 4 to the chain 8 is achieved. When the contact surface 20A of the notch 20 develops a play S by the elongation of the chain 8, the collar 30 used previously is removed and a collar 30' whose outer diameter is slightly larger, is fitted in place instead of the collar 30, and thus the play on the contact surface 20A of the notch 20 can be eliminated.

      SOLUTION: The sewage residue in a stream from a stream trough 10 is subjected to crushing of a first step by an inflow side crusher 12 and once is sent to an acceptance water tank 14 from an inflow port 30. The sewage residue in the acceptance water tank 14 is subjected to crushing of a second step by an outflow side crusher 16 from an outflow port 32 and then is discharged from a suction pipe 18 under suction by a discharge pump 20. The acceptance water tank 14 is constituted of a rectangular upper side box part 14a having the inflow port 30 and a conical lower side box part 14b narrowing downward and having the outflow port 32. Thereby a straight water stream can be obtained and the sewage residue subjected to crushing of the first step by the inflow side crusher 12 is sent to the outflow side crusher 16 without causing flocculation in the acceptance water tank 14 and crushing of the second step can be efficiently performed.
