Separator apparatus

Claim 2

Separator apparatus for separating a mixture of liquids and solids and comprising; a separating tank; means for passing a mixture of liquids and solids to said separator tank; screen means in said separator tank dividing said separator tank into a mixture compartment, on one side of said screen means, and a filtrate compartment on the other side of said screen means; mixture conduit means for removing mixture from said mixture compartment of said separator tank; filtrate conduit means extending from said filtrate compartment of said separator tank; scraper mounting frame means adjacent to said screen means; conveyor means movable on said mounting frame means; scraper bar means on said conveyor means for moving over said screen means and moving material therefrom, and, movable frame supporting means at at least one end of said mounting frame means, said mounting frame means being movable in said frame supporting means, whereby to permit said mounting frame means, and said conveyor means and said scraper bars to move momentarily away from said screen means to avoid an obstruction.

Claim 3

Separator apparatus as claimed in claim 1 wherein said frame supporting means comprise at least two generally U-shaped slotted members, and including rod members on said mounting frame means extending into said U-shaped slotted members, and being slidably movable therealong to provide movement of said mounting frame means as aforesaid.

Claim 4

Separator apparatus as claimed in claim 2 wherein said frame means and said screen means are mounted at an angle in said tank, and wherein said frame means defines upper and lower ends, said frame supporting means being located adjacent said lower end, and including frame fastening means adjacent an upper end of said mounting frame means, said frame fastening means being releasably attachable to said tank, and securing the same in position therein and permitting movement of at least the lower end of said frame ends.

Claim 5

Separator apparatus as claimed in claim 3 wherein said frame supporting means comprise at least two generally U-shaped slotted members, and including rod members on said mounting frame means extending into said U-shaped slotted members, and wherein said frame means and said conveyor means are removable from said tank, by disengagement of said frame fastening means, and releasing said rod members from said U-shaped members.

Claim 6

Separator apparatus as claimed in claim 1 including movable flow metering means associated with said mixture conduit means, and motor means for moving the same, whereby to continuously clear said mixture conduit means and simultaneously regulate flow of said mixture from said mixture compartment of said separator tank.

Claim 7

Separator apparatus as claimed in claim 5 wherein said flow metering means comprises a spiral auger member, and rod means on which said auger member is mounted, said rod means extending upwardly through said tank, and said motor means being mounted on an upper portion of said tank above the level of liquids therein.

Claim 8

Separator apparatus as claimed in claim 5 including control means for controlling of mixture to and from said separator tank, and for filling and emptying same, and for causing operation of said scraper means only when said separator tank is empty of said mixture, and ensuring that said scraper means remains stationary while said tank contains said mixture.

Claim 9

A separator system for separating a mixture of liquids and solids and comprising; a mixture storage tank; a filtrate accumulator tank, said storage and accumulator tanks being located side by side closely adjacent to one another; a separator tank being mounted above said storage and accumulator tanks; mixture conduit means connected between said storage tank and said separator tank for passing unfiltered mixture to said separator tank; return conduit means for returning mixture from said separator tank to said storage tank, unfiltered; screen means in said separator tank dividing same into a mixture compartment on one side and a filtrate compartment on the other side; solids removal means operable to clear solids from said screen means when said separator tank is empty, and being out of operation when said tank is full of mixture; filtrate conduit means extending between said filtrate compartment of said separator tank and said accumulator tank, for passing filtrate from said filtrate compartment to said accumulator tank; supply pump means in said storage tank, intermittently operable to pump unfiltered mixture from said storage tank to said separator tank; filtrate pump means in said accumulator tank, intermittently operable to pump filtrate from said accumulator tank; level sensing means in said storage tank and in said accumulator tank, for controlling operation of said respective supply and filtrate pump means; separator tank level sensing means for sensing the level of mixture in said separator tank and controlling said supply pump means for operation thereof, and, control means for discontinuing operation of said pump means whereby said separator tank may be permitted to drain, and said control means being further operable to subsequently cause commencement of operation of said solids removal means, when said separator tank has drained, and subsequently cause termination of such operation, and then causing commencement of operation of said pump means whereby to refill said tank with mixture once more.

Claim 10

A separator system for separating a mixture of liquids and solids and comprising; a mixture storage tank; a filtrate accumulator tank, said storage and accumulator tanks being located side by side closely adjacent to one another; a separator tank being mounted above said storage and accumulator tanks; mixture conduit means connected between said storage tank and said separator tank for passing unfiltered mixture to said separator tank; return conduit means for returning mixture from said separator tank to said storage tank, unfiltered; screen means in said separator tank dividing same into a mixture compartment on one side and a filtrate compartment on the other side; solids removal means operable to clear solids from said screen means when said separator tank is empty, and being out of operation when said tank is full of mixture; filtrate conduit means extending between said filtrate compartment of said separator tank and said accumulator tank, for passing filtrate from said filtrate compartment to said accumulator tank; supply pump means in said storage tank, intermittently operable to pump unfiltered mixture from said storage tank to said separator tank; filtrate pump means in said accumulator tank, intermittently operable to pump filtrate from said accumulator tank; level sensing means in said storage tank and in said accumulator tank, for controlling operation of said respective supply and filtrate pump means; separator tank level sensing means for sensing the level of mixture in said separator tank and controlling said supply pump means for operation thereof, and, control means for discontinuing operation of said pump means whereby said separator tank may be permitted to drain, and said control means being further operable to subsequently cause commencement of operation of said solids removal means, when said separator tank has drained, and subsequently cause termination of such operation, and then causing commencement of operation of said pump means whereby to refill said tank with mixture once more.
