Abstract
Abstract Apparatus is disclosed for separation of liquid and solid waste materials from a mixture or other combination of such materials. A container is provided with a vertically disposed interior screen or perforated wall that is capable of retaining solid material while permitting liquid material to pass therethrough. The perforated wall divides the container into first and second portions. Waste material is provided to the first portion, and liquid material is removed from the second portion. Preferably disposed in the first portion is an onion bag or other porous, screening or filtering material for receiving the combination of liquid and solid material and retaining of the solid material. Liquid material can be removed from the second portion via a drain, or alternatively by a pump controlled by a liquid level sensor. The pump would be operated whenever the liquid level sensor sensed a sufficiently high predetermined level of liquid in the container.

Claim 1
Independent Claim
326 words
Apparatus for receiving effluent comprised of solid and liquid effluent material and separating the solid effluent material from the liquid effluent material for the purpose of collection, said apparatus comprising: a container having a closed bottom surface and an open top end facing opposite said closed bottom surface; means for separating the container into separate respective solid and liquid effluent chambers, said means for separating extending in a plane substantially perpendicular to said closed bottom surface; means for directing the solid and liquid effluent material to the open top end of the container into said solid effluent chamber; a porous bag disposed in said solid effluent chamber for substantially separating liquid effluent material from solid effluent material and having an open top end; said means for directing the effluent material having an outlet port disposed within said open top end of said container and aligned with said open top end of said porous bag, said outlet port for directing said effluent to fall by gravity into said open top end of said porous bag; means attached to said container for disposing the porous bag such that said porous bag is hanging in said solid effluent chamber and such that said porous bag is positioned to receive the solid and liquid effluent material therein; means disposed in the liquid effluent chamber for enabling collected liquid effluent material received from said porous bag, absent any substantial solid effluent material removed by said porous bag, to be directed to a liquid drain; wherein said means for disposing the porous bag is arranged to dispose the porous bag above the closed bottom surface of said container with a gap between said bag and the closed bottom surface of said container; said container including means for releasably supporting said means for disposing said porous bag; and, said porous bag including means in the vicinity of said bag open top end for releasable connection to said means for disposing the porous bag.

Apparatus for receiving effluent comprised of solid and liquid effluent material and separating the solid effluent material from the liquid effluent material for the purpose of collection, said apparatus comprising: a container having a closed bottom surface and an open top end facing opposite said closed bottom surface; means for separating the container into separate respective solid and liquid effluent chambers, said means for separating extending in a plane substantially perpendicular to said closed bottom surface; means for directing the solid and liquid effluent material to the open top end of the container into said solid effluent chamber; a porous bag disposed in said solid effluent chamber for substantially separating liquid effluent material from solid effluent material and having an open top end; said means for directing the effluent material having an outlet port disposed within said open top end of said container and aligned with said open top end of said porous bag, said outlet port for directing said effluent to fall by gravity into said open top end of said porous bag; means attached to said container for disposing the porous bag such that said porous bag is hanging in said solid effluent chamber and such that said porous bag is positioned to receive the solid and liquid effluent material therein; means disposed in the liquid effluent chamber for enabling collected liquid effluent material received from said porous bag, absent any substantial solid effluent material removed by said porous bag, to be directed to a liquid drain; wherein said means for disposing the porous bag is arranged to dispose the porous bag above the closed bottom surface of said container with a gap between said bag and the closed bottom surface of said container; said container including means for releasably supporting said means for disposing said porous bag; and, said porous bag including means in the vicinity of said bag open top end for releasable connection to said means for disposing the porous bag.
Claim 3
Dependent Claim
27 words
Apparatus as recited in claim 1 wherein said means separating the container into separate chambers includes a perforated wall that is disposed substantially vertically in the container.
Claim 4
Dependent Claim
20 words
Apparatus as recited in claim 2 wherein said hanging porous bag is disposed substantially parallel to said vertical perforated wall.
Claim 5
Dependent Claim
18 words
Apparatus as recited in claim 1 wherein said means disposed in the liquid effluent chamber includes a pump.
Claim 6
Dependent Claim
17 words
Apparatus as recited in claim 4 including conduit means for coupling the pump to the liquid drain.
Claim 7
Dependent Claim
23 words
Apparatus as recited in claim 5 including float means for controlling the pump as a function of the liquid level in the container.
Claim 8
Dependent Claim
32 words
Apparatus as recited in claim 1 wherein said solid effluent chamber and said liquid effluent chamber together have a single planar continuous level bottom surface defined by the bottom of said container.
