Abstract
An improved waste stream homogenizing apparatus and method includes a housing with an inlet port configured to receive a waste stream and direct the waste stream to an exit port. A central shaft configured to rotate within the housing. A blade with a cutting edge connected with a blade hub, where the blade hub is connected with the central shaft and a sizing screen with sizing holes, the sizing holes arranged in a non-concentric pattern on the sizing screen, where the cutting edge of the blade is in contact with the sizing screen where the waste stream is forced past the cutting edge and the sizing screen as the central shaft rotates.
Claims13
An improved waste stream homogenizing apparatus comprising:
- a housing (12) defining an interior volume, an inlet port (14) extending through a housing wall;
- a central rotatable shaft (18) extending through the interior volume of the housing (12);
- a first stage volume (48) within the interior volume and bounded by the housing walls and a first sizing screen (26) having holes (28) extending therethrough, said holes (28) being positioned in a spiral pattern (34), a first stage blade (20) with a cutting edge connected with a first stage blade hub (24) rotatably positioned within the first stage volume (48) and being in contact with the first sizing screen (26), wherein the first stage blade hub (24) is connected to the central rotatable shaft (18), the first stage volume (48) being in fluid communication with the inlet port (14) for receiving a waste stream to be homogenized;
- and
- a second stage volume (50) within the interior volume and downstream of the first stage volume (48), having a second sizing screen (26) with holes (28) extending therethrough, said holes (28) being positioned in a spiral pattern (34), a second stage blade (20) with a cutting edge connected with a second stage blade hub (24) rotatably positioned within the second stage volume (50) and being in contact with the second sizing screen (26), wherein the second stage blade hub (24) is connected with the central rotatable shaft (18), the second stage volume (50) being in fluid communication with an exit port (16) downstream of the second sizing screen (26) and extending through a housing wall to permit waste material that has been homogenized to exit the housing (12).
A method of homogenizing a waste stream comprising the steps of:
- providing a homogenizing apparatus including:
- a housing (12) defining an interior volume, an inlet port (14) extending through a housing wall;
- a central rotatable shaft (18) extending through the interior volume of the housing (12);
- a first stage volume (48) within the interior volume and bounded by the housing walls and a first sizing screen (26) having holes (28) extending therethrough, said holes (28) being positioned in a spiral pattern (34), a first stage blade (20) with a cutting edge connected with a first stage blade hub (24) rotatably positioned within the first stage volume (48) and being in contact with the first sizing screen (26), wherein the first stage blade hub (24) is connected to the central rotatable shaft (18), the first stage volume (48) being in fluid communication with the inlet port (14) for receiving a waste stream to be homogenized;
- and
- a second stage volume (50) within the interior volume and downstream of the first stage volume (48), having a second sizing screen (26) with holes (28) extending therethrough, said holes (28) being positioned in a spiral pattern (34), a second stage blade (20) with a cutting edge connected with a second stage blade hub (24) rotatably positioned within the second stage volume (50) and being in contact with the second sizing screen (26), wherein the second stage blade hub (24) is connected with the central rotatable shaft (18), the second stage volume (50) being in fluid communication with an exit port (16) downstream of the second sizing screen (26) and extending through a housing wall to permit waste material that has been homogenized to exit the housing (12);
- introducing a waste stream to be homogenized into the inlet port;
- and
- withdrawing a homogenized waste stream from the exit port.
