Abstract
A continuously operable apparatus including a rotatably positioned container having an open upper end and with a stack of annular discs in the container where the discs are of uniform inner and outer diameters for a major portion of the height of the stack but being of progressively smaller inner diameters approaching the upper end of the stack to form a conically shaped inner surface. A helical scraper means is positioned within the stack of discs and has an outer peripheral surface complementary to the inner surfaces of the stacked discs. Brake means are operatively associated with a top member that has the scraper means secured thereto to produce relative rotation of the helical scraper re the stack of discs for scraping solid particles therefrom to deliver them to the upper end of the apparatus.
Claims10
A centrifugal scraper and separator apparatus for fluids having solid particles therein, comprising
- a container having an open upper end,
- means mounting said container on a vertical axis for rotation thereof and adapted for connection to a drive means,
- an inner container having an open upper end operatively positioned within said first container for rotation therewith,
- a stack of annular discs in said inner container, said discs being of uniform inner and outer diameters for a major portion of the height of the stack but being of progressively smaller inner diameters approaching the upper end of the stack to form a conically shaped inner surface, said discs as stacked having fluid flow passages therethrough from their inner to their outer diameters,
- a vertically positioned inlet tube extending from above said container down into said inner container for feed or a fluid mix thereto,
- a helical scraper means supported on said inner container positioned within said stack of discs and having a cylindrical lower section and a conically shaped upper portion for scraping engagement with the inner surfaces of said discs, the convolutions of said scraper means extending upwardly,
- a collector plate at the upper end of said stack of discs, which plate has a center opening therein, the upper end of said scraper means extending through said opening,
- means to remove solids deposited on said collector plate by said scraper means,
- a brake member engaging the upper end of said scraper means,
- means to remove fluids flowing through said stack of discs, and
- brake means for said brake member to engage the same to slow rotation of such member and said scraper means relative to said stack of discs.
A centrifugal scraper and separator apparatus for fluids having solid particles therein, comprising
- a container having an open upper end,
- driver means mounting said container on a vertical axis for rotation thereof,
- a stack of annular discs in said container, said discs being of uniform inner and outer diameters for a major portion of the height of the stack but being of progressively smaller inner diameters approaching the upper end of the stack to form a conically shaped inner surface, said discs outer peripheries being spaced from said container, clearance for flow of fluids being provided between the discs of said stack of discs,
- a vertically positioned inlet tube extending from above said container down into said container,
- a helical scraper means positioned within said stack of discs and having a cylindrical lower section and a conically shaped upper portion for scraping engagement with the inner surfaces of said discs, the convolutions of said scraper means extending upwardly,
- a centrally open collector means at the upper end of the said stack of discs, the upper end of said scraper means extending through said collector means,
- suction means to remove fluids flowing through said stack of discs, and
- brake means for said scraper means to operatively engage the same to slow rotation thereof in relation to said stack of dics.
