Abstract
A high shear rotating disc filter having a hollow interior and constructed of a porous material such as sintered metal or ceramic with finely structured openings. The disc is mounted and secured onto a hollow shaft. The hollow shaft is connected to a vacuum source, external to the filter, that allows for the passage of the filtrate to a receiver. There are elongated slots in the wall of the shaft which provide the passage of filtrate from the disc. The shaft provides rotational force for the discs.
Claims13
A high shear rotating disc filter assembly in a filtering system for filtering a slurry comprised of liquid and very small particles, said filtering system having at least a feed tank with a slurry input means, a slurry output means, and a slurry recycle input means, a receiver tank, and a vacuum pump, comprising:
- a plurality of rotating discs constructed of a porous material, each said disc having a hollow interior, each said disk being mounted on a shaft;
- an elongated shaft for holding said discs, said shaft having a hollow interior, said shaft having a first end and a second end, said ends defining an elongated, longitudinal shaft axis, said second end being connected to said vacuum pump and said receiver tank, said first end being connected to a rotational drive means, said shaft having a plurality of elongated slots opening into said shaft hollow interior and into said disc interiors;
- a liquid-tight vessel enclosing said discs and a portion of said shaft holding said discs, said vessel being connected to said feed tank slurry output means for receiving said slurry, said feed tank having an output means connected to said feed tank slurry recycle input means.
