Abstract
A large percentage of solids are removed from a manure slurry when the slurry is run across a sloped screen separator. The sloped screen on the separator has very small openings. In addition, the separator has a water line with spray heads formed across the sloped screen. The spray heads direct water under pressure onto the sloped screen. Further, the separator controls the air flow through the sloped screen.
Claims39
A separator comprising:
- an input compartment having an input opening and an output ledge, a manure slurry being pumped into the input compartment through the input opening, and flowing out over the output ledge;
- a sloped screen connected to the output ledge of the input compartment, the sloped screen having a plurality of screen openings, the screen openings having a size that ranges from a lower size to an upper size, the lower size being greater than a size that requires shaking before the manure slurry will fall through the screen openings, the upper size being equal to or less than 1.0 mm, the manure slurry flowing out over the output ledge onto the sloped screen when the manure slurry is pumped into the input compartment;
- and
- a collection compartment connected to the sloped screen, the collection compartment having an air flow opening and a slurry exit opening, and receiving a screened slurry that falls through the sloped screen when the manure slurry is pumped into the input compartment, the screened slurry flowing out through the slurry exit opening.

A separator comprising:
- an input compartment having an input opening and an output ledge, a manure slurry being pumped into the input compartment through the input opening, and flowing out over the output ledge;
- a sloped screen connected to the output ledge of the input compartment, the sloped screen having a plurality of screen openings and a width, the manure slurry flowing out over the output ledge onto the sloped screen when the manure slurry is pumped into the input compartment;
- a collection compartment connected to the sloped screen, the collection compartment having an air flow opening and a slurry exit opening, and receiving a screened slurry that falls through the sloped screen when the manure slurry is pumped into the input compartment, the screened slurry flowing out through the slurry exit opening;
- a water pipe connected to the collection compartment that extends across the sloped screen;
- and
- a plurality of spray heads connected to the water pipe, the spray heads outputting a liquid at a rate, the rate ranging from equal to or greater than 113 liters per hour to equal to or less than 1362 liters per hour per approximately 0.31 meters of the width.
