Definitions

  • the container 700 has an external shape which resembles an interior shape of the dewatering drum 652. Namely, the container 700 has a side wall portion 700c, a bottom portion 700b and a protuberant portion 700a whose shapes match an inner side surface 652c, the bottom surface 652b and the protuberance 652a, respectively. However, an outside diameter of the side wall portion 700c is formed slightly smaller than an inside diameter of the inner side surface of the dewatering drum 652.
  • the gap ⁇ d By the gap ⁇ d being ensured, frictional resistance is reduced that would otherwise be produced between the inner side surface 652c of the dewatering drum 652 and the container 700, thereby making it possible to easily lift up the container 700 in which processing refuse are built up.
  • the placing operation is made easy.
  • the center of gravity of the container 700 is made to coincide substantially with a rotational axis of the dewatering drum 652.
  • the lid member 658 and the filter 654 are press fitted to each other by the projecting portion 703 (refer to Fig. 2B ). Namely, by the filter 654 being held between the projecting portion 703 and the lid member 658 to thereby be collapsed, the filter 654 also functions as a packing for preventing grinding water from flowing from a gap between the container 700 and the lid member 658. With this configuration, the flow of grinding water which is discharged through the filter 654 into the gap ⁇ d is suppressed as much as possible during centrifugal separation.
  • a removal jig 750 includes a holding portion 752 to be held by the hand of the operator and two hooks (hook members) 751 which are fixed to a distal end of a shaft 753 which extends from the holding portion 752.
  • an engagement portion 702 to be caught by (which is brought into engagement with) the hooks 751 of the removal jig 750 is formed at an upper end of the protuberant portion 700a which is situated at the center of the container 700.
  • the engagement portion 702 is made up of two holes 702a so as to match the hooks so provided.
  • the engagement portion 802 is constructed in such a manner as to be bent inwards of the container 800 by a hinge provided in a position which coincides with a side wall of the container 800.
  • the distal end portion 861 of the removal jig 860 is allowed to be inserted into the opening 803.
  • Restricting members 805 for restricting the rotation of the engagement portions 802 are provided on an inside of the container 800, whereby the sinking of the engagement portions 802 is prevented by the restricting members 805.
