Abstract
A pair of rotatable shafts are mounted within a housing. The shafts are spaced apart along the same plane with each shaft having a plurality of longitudinally spaced disks mounted thereon. The space between the shafts and the dimensions of the disks are such that disks on each shaft extend into the space between adjacent disks on the other shaft to provide pressing areas. One shaft is rotated clockwise; the other shaft is rotated counterclockwise. A slurry or semi-solid is fed into the in-running sides of the disks. A cake forms on the disks by the flow of liquid through liquid passageways in the disks. Pressing to a high consistency takes place in the pressing areas. The cake thus formed is removed from the disks at the out-running sides of the disks.
Claims5
A disk press comprising:
- a pair of rotatable shafts, said shafts being spaced apart along the same plane;
- a plurality of longitudinally-spaced disks mounted on each rotatable shaft, the space between the shafts and the dimensions of the disks being such that disks on each shaft extend into the space between adjacent disks on the other shaft to provide pressing areas;
- means for rotating one shaft clockwise and the other shaft counterclockwise;
- means for feeding wet material into the in-running sides of the disks;
- means for forming cakes on the in-running sides of disks;
- said cakes being pressed to a higher consistency in the pressing areas;
- and longitudinally-spaced sets of doctors extending into the spaces between the disks for removing the pressed cake from the disks at the out-running side of the disks, said doctors being constructed to provide separate in-running and out-running sides of the disks, and prevent removed cake from re-entering the in-running sides of the disks.
A disk press comprising:
- a housing;
- a pair of rotatable shafts mounted in said housing, said shafts being spaced apart along the same plane;
- a plurality of longitudinally-spaced disks mounted on each rotatable shaft, the space between the shafts and the dimensions of the disks being such that disks on each shaft extend into the space between adjacent disks on the other shaft to provide pressing areas;
- means for rotating one shaft clockwise and the other shaft counterclockwise;
- means for feeding a slurry into the housing at a location such that slurry enters the housing at the in-running sides of the disks;
- means for forming cakes on the in-running sides of the disks;
- said cakes being pressed to a higher consistency in the pressing areas;
- longitudinally-spaced sets of doctors extending into the spaces between the disks for removing the pressed cake from the disks at the out-running sides of the disks, said doctors being constructed to provide separate in-running and out-running sides of the disks, and prevent removed cake from re-entering the in-running side of the disks;
- and a dilution liquid inlet for flowing dilution liquid into the housing at the out-running sides of the disks to form a low consistency material suspension.
