Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
190 words
A screw type dewatering machine including inner and outer sleeves disposed coaxial with each other, an annular space chamber defined between said inner and outer sleeves, a charge port for material to be dewatered formed in one end of said outer sleeve, a discharge port for said material formed in one end of said annular space chamber, and a coil-like screw rotatably disposed in said annular space chamber to convey toward said discharging port the material to be dewatered charged into said annular space chamber through said charging port, the other end of said annular space chamber being adapted to serve as a dewatering zone to compresses said material to squeeze the water therefrom, said water being discharged to the outside through a discharge screen installed on the inner and/or outer sleeve, the other end of said annular space chamber being adapted to serve as a plug zone to compress material to be dewatered, said screw type dewatering machine being characterized in that a support ring is attached to the outer peripheral surface of one end of said coil-like screw, said support ring being rotatably supported by the outer sleeve.
Claim 2
Dependent Claim
37 words
A screw type dewatering machine as set forth in Claim 1, characterized in that the thickness of the region of one end where the support ring is attached thereto is greater than that of the other end.
Claim 3
Dependent Claim
219 words
A screw type dewatering machine including inner and outer sleeves disposed coaxial with each other, an annular space chamber defined between said inner and outer sleeves, a charge port for material to be dewatered formed in one end of said outer sleeve, a discharge port for said material formed in one end of said annular space chamber, and a coil-like screw rotatably disposed in said annular space chamber to convey toward said discharging port the material to be dewatered charged into said annular space chamber through said charging port, one end of said annular space chamber being adapted to serve as a dewatering zone to compresses said material to squeeze the water therefrom, the water being discharged to the outside through a discharge screen installed on the inner and/or outer sleeve, the other end of said annular space chamber being adapted to serve as a plug zone to compress material to be dewatered, said screw type dewatering machine being characterized in that it further includes; a rotary shaft body inserted in the outer sleeve through said discharge port, one end of said rotary shaft body being connected to one end of the coil-like screw, the other end of said rotary shaft body being supported by a support member, and a rotary driving device for rotating said rotary shaft body.
