Abstract
The present invention provides a flow disrupter within the flow path of a slurry comprising a desired particulate matter and a transport fluid so as to impart a force angularly disposed to an otherwise obtained direction of travel, thereby preventing the formation of a sheet of aggregated particulates against the screen surface. In a method in accord with the present invention a force is imparted to the desired particulate matter in an angular direction to the direction of travel.
Claims13
A centrifugal dryer for separating and drying a particulate material entrained within a transport fluid, said dryer comprising a dryer section, said dryer section including a housing, a screen disposed within the housing and having and inner and an outer surface, and a rotor, wherein
- said dryer includes a flow disrupter comprising a ramp, said disrupter attached to said screen and said ramp directed inwardly;
- said screen includes at least first and second cooperating latch assembly loops, each said loop including an attachment portion for attachment thereof to said screen and a loop portion, and wherein said disrupter is attached to said first latch assembly loop portion;
- and
- said disrupter further includes a disrupter attachment portion, said ramp and said disrupter attachment portion having substantially planar configurations, wherein said ramp and said disrupter attachment portion form an angle θ relative to each other and said disrupter attachment portion has a substantially semi-circular configuration and said first loop assembly loop portion has a substantially circular configuration, said first loop assembly loop portion being received within said disrupter attachment portion.
A centrifugal dryer for separating and drying a particulate material entrained within a transport fluid, said dryer comprising a dryer section including
- a pair of screen support hoops;
- a flow disrupter bar attached to and extending between said support hoops;
- a screen attached to said flow disrupter bar;
- and
- a rotor,
- wherein:
- said flow disrupter bar includes a ramp extending inwardly;
- said screen includes a pair of ends and a first of said ends includes an outwardly directed flange with at least one through hole;
- said flow disrupter bar includes at least one threaded hole corresponding to said at least one flange through hole;
- and
- said dryer further includes a screen clamp bar having at least one through hole corresponding to said at least one flange through hole,
- wherein said screen is attached to said flow disrupter bar by a bolt extending through said screen clamp bar through hole, said flange through hole and into threaded engagement with said screen disrupter bar threaded hole.
