Abstract
An apparatus for partial dehydration of a sludge in the centrifugal field of a centrifuge wherein the residual moisture of the sludge is substantially reduced with a comparatively low compression of the sludge, and the non-effective cone length of the centrifuge is reduced without shortening the sludge dwell time. The invention includes an arrangement of agitator elements within the centrifugal drum, coupled with a following shearing centrifuge and decanter, the shearing centrifuge being connected at the discharge of the centrifugal drum.
Claims14
An apparatus for dewatering sludge in the centrifugal field of a solid jacket centrifuge comprising:
- a centerfuge drum,
- agitator elements situated within said centrifuge drum, said agitator elements including impelling means thereon,
- means for causing relative movement between some of said agitator elements and others of said agitator elements in a direction parallel to the rotational axis of said centrifuge,
- means for adjusting the amount of said relative movement between said agitator elements,
- means for adjusting the rotational speed of said agitator elements, and
- means for adjusting the angle of incidence of some of said agitator elements.
