Abstract
A dewatering screen includes a frame, a deck mounted upon the frame, and the deck having a plurality of apertures therein. The frame is mounted on a base with a vibration generator for imparting vibration to the deck. A delivery device delivers wet particulate material to be dewatered onto the deck, and there is at least one dividing wall extending across a portion of the deck, the dividing wall(s) separating the deck into a material dewatering region and one or more water drainage regions. The delivery device delivers wet particulate material to be dewatered onto the material dewatering region of the deck.
Claims18
A dewatering screen comprising:
- a frame;
- a deck mounted upon said frame, said deck having a plurality of apertures therein, an upstream end, and a downstream end;
- a vibration generator for imparting vibration to said deck;
- and
- at least one dividing wall extending across a portion of said deck, said at least one dividing wall partitioning said deck into a material dewatering region and one or more water drainage regions, and said at least one dividing wall extends from said upstream end toward said downstream end of said deck;
- side walls on either side of said deck;
- a rear wall extending between said side walls at said upstream end of said deck;
- said at least one dividing wall extending from said rear wall of said deck towards said downstream end of said deck;
- wherein said material dewatering region is configured to receive wet particulate material from a delivery device for dewatering the wet particulate material at said deck.
A dewatering screen comprising:
- a frame;
- a deck mounted upon said frame, said deck having a plurality of apertures therein;
- a vibration generator for imparting vibration to said deck;
- and
- at least one dividing wall extending across a portion of said deck, said at least one dividing wall partitioning said deck into a material dewatering region and one or more water drainage regions;
- wherein said material dewatering region is configured to receive wet particulate material from a delivery device for dewatering the wet particulate material at said deck;
- and
- wherein drainage apertures, slots or channels are provided in at least a portion of said at least one dividing wall to provide an alternative route for water to pass from said material dewatering region into said one or more water drainage regions and/or into a sump located beneath said deck.
A dewatering screen comprising:
- a frame;
- a deck mounted upon said frame, said deck having a plurality of apertures therein;
- a vibration generator for imparting vibration to said deck;
- and
- at least one dividing wall extending across a portion of said deck, said at least one dividing wall partitioning said deck into a material dewatering region and one or more water drainage regions;
- wherein said material dewatering region is configured to receive wet particulate material from a delivery device for dewatering the wet particulate material at said deck;
- and
- wherein the height of said at least one dividing wall varies along its length, the height being greatest at its upstream end and least at its downstream end.
