| (54) | Vertical type solid-liquid separating apparatus |
| (57) A vertical type solid-liquid separating apparatus (1) comprises a frame; an outer
cylinder (2) rotatably supported on the frame; an inner cylinder (3) coaxially and
rotatably disposed within the outer cylinder to define an annular separating chamber
therebetween; a screw blade (5) fixedly attached to the outer circumference of the
inner cylinder so that a small gap remains between the screw blade and the inner wall
of the outer cylinder. An original liquid is supplied into the separating chamber.
The separated, cleaned liquid is discharged from an upper part of the separating chamber
and sludge is discharged from a lower part of the separating chamber. The driving
means comprises a first motor (21) for driving the outer cylinder, a planetary means
(20) connected to both the outer cylinder and the inner cylinder, and a second motor
(22) for setting a speed difference of the planetary means, so that the outer and
inner cylinders are rotated in a same rotational direction and the rotational speed
of the outer cylinder is slightly larger than that of the inner cylinder. |
