Abstract

A two-vector centrifuge rotates on a central axis, while each centrifuge drum also rotates on the drum's own axis. The inside of each drum has flighting or threads to direct and force material to the bottom of the drum as the two-vector centrifuge rotates. Perforations in the top part of the drum allow liquids to be expelled from the drum, while dried, solid material is ejected though a gap in the bottom of the drum. A pair of troughs keep the ejected liquid fraction separate from the ejected solid fraction, and each fraction is removed from the centrifuge while the centrifuge is operating, allowing the centrifuge to run for extended periods without needing to be cleaned or have accumulated material removed.

Claims4

Dependent claims

A centrifuge comprising a rotor, a rotating platform comprising a plurality of drum openings, and a plurality of drums in which

(a) said rotating platform has a central primary axis,
(b) each said drum has a central axis of rotation,
(c) each said drum opening houses a drum,
(d) the rotor is connected to the rotating platform such that operation of the rotor causes the rotating platform to rotate on the central primary axis, and
(e) each drum rotates on the axis of rotation of the drum when said rotating platform rotates on the central primary axis,
(f) each said drum comprises an inside, an inside surface, an outside surface, a top portion, and a bottom portion,
(g) said inner surface comprises a downward movement means,
(h) said top portion comprising perforations that allow passage of liquids such as water from the inside of the drum to the outside of the drum,
(i) said top portion comprises an inlet, and
(j) said bottom portion comprises an egress.

7 more elements

A centrifuge comprising a housing, a rotor, a rotating platform comprising a plurality of drum openings, and a plurality of drums in which

(a) said rotating platform has a central primary axis,
(b) said rotating platform is largely planar,
(c) each said drum has a central axis of rotation,
(d) each said drum opening houses a drum,
(e) the rotor is connected to the rotating platform such that operation of the rotor causes the rotating platform to rotate on the central primary axis, and
(f) the rotating platform is in communication with each said drum such that each drum turns on the axis of rotation of the drum when said rotating platform rotates on the central primary axis,
(g) each said drum comprises an inside, an inside surface, an outside surface, a top portion, and a bottom portion,
(h) said inner surface comprises a downward movement means,
(i) said top portion comprises perforations that allow passage of liquids such as water from the inside of the drum to the outside of the drum,
(j) said top portion comprises an inlet,
(k) said bottom portion comprises an egress,
(l) Said housing comprising an inside top space and an inside bottom space separated by said rotating platform,
i) said inside top space comprises a liquid trough and a liquid egress port,
a) said liquid trough comprises a slant and a nadir terminating at the liquid egress port,
ii) said inside bottom space comprises a solid trough, a scraper, and a solid egress port, said scraper causing solids ejected through the solid egress port to move in the solid trough to the solid egress port,
(m) the top portion of each drum is above the level of the liquid trough, and
(n) the egress of the bottom portion of each drum is below the level of the liquid trough.
