Abstract
Abstract An apparatus for treating waste material contained in drums comprises a conveyor for moving said drums to a purging chamber having an inlet door and outlet door, a conveyer in said purging chamber for moving said drums through said outlet door, a conveyer outside said purging chamber for moving said drums to a shear station where the bottom lids of the drums are sheared off, a compactor chamber for receiving and compacting said drums and extruding said waste materials therein, and a sorter for sorting the waste materials into liquid and solid components and conveying said sorted liquids and solids to respective storage facilities.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
182 words
A waste treatment apparatus for separating liquid/sludge and solids components of waste materials, comprising: first conveyer means for conveying upright large industrial-type drums containing waste materials including said liquid/sludge component and said solids component; a purging chamber for receiving said upright drums from said first conveyer means, said purging chamber having an inlet door and an outlet door; second conveyer means within said purging chamber for conveying said upright drums therefrom; third conveyer means outside said purging chamber for conveying said upright drums to shear means and to compactor means; shear means, disposed in the path of said third conveyer means, for shearing off only the bottom lids of said upright drums being conveyed by said conveyer means; compactor means for compacting said sheared drums received from said shear means, each drum being a cylinder, and the compaction being in the direction of the cylindrical axis, whereby the waste materials are extruded from the bottom of said upright drums; and sorting means for receiving said extruded waste materials and for separating them into a liquid/sludge waste component and a solid waste component.
Claim 2
Dependent Claim
182 words
A waste treatment apparatus for separating liquid/sludge and solids components of waste materials, comprising: first conveyer means for conveying upright large industrial-type drums containing waste materials including said liquid/sludge component and said solids component; a purging chamber for receiving said upright drums from said first conveyer means, said purging chamber having an inlet door and an outlet door; second conveyer means within said purging chamber for conveying said upright drums therefrom; third conveyer means outside said purging chamber for conveying said upright drums to shear means and to compactor means; shear means, disposed in the path of said third conveyer means, for shearing off only the bottom lids of said upright drums being conveyed by said conveyer means; compactor means for compacting said sheared drums received from said shear means, each drum being a cylinder, and the compaction being in the direction of the cylindrical axis, whereby the waste materials are extruded from the bottom of said upright drums; and sorting means for receiving said extruded waste materials and for separating them into a liquid/sludge waste component and a solid waste component.
Claim 3
Dependent Claim
35 words
A waste treatment apparatus as defined in claim 1, wherein: said shear means is fixed, and each drum is moved thereagainst by said third conveyer means, whereby the lid of the drum is sheared off.
Claim 4
Dependent Claim
49 words
A waste treatment apparatus as defined in claim 2, wherein: said compactor means has a chamber for receiving said drums, an outlet adjacent the open end of a sheared drum, and a compactor head for compacting said sheared drum, whereby the waste materials therein are extruded through said outlet.
Claim 5
Dependent Claim
59 words
A waste treatment apparatus as defined in claim 3, wherein: said sorting means comprises a housing which is located beneath said compactor means and which has separator means for separating the waste materials from said drums into solid and liquid/sludge components, and which has discharge means for discharging said solid and liquid/sludge waste components to separate storage containers, respectively.
Claim 6
Dependent Claim
35 words
A waste treatment apparatus as defined in claim 4, wherein: said separator means comprises a perforated floor which permits passage of liquids and sludge and blocks passage of solids which thereby collect on said floor.
Claim 7
Dependent Claim
68 words
A waste treatment apparatus as defined in claim 5, wherein said discharge means comprises: valve means for controlling the discharge of solids collected on said perforated floor and having a normally closed discharge port; valve-controller means for opening said discharge port when a predetermined amount of solids has collected on said perforated floor; and means for moving said collected solids from said floor to said open discharge port.
Claim 8
Dependent Claim
23 words
A waste treatment apparatus as defined in claim 5, further comprising chute means, disposed beneath said shear means, for receiving the sheared lids.
Claim 9
Dependent Claim
23 words
A waste treatment apparatus as defined in claim 7, further comprising: a water-containing tank beneath said chute means for receiving said sheared lids.
Claim 10
Dependent Claim
34 words
A waste treatment apparatus as defined in claim 8, further comprising: a conveyer in said compactor for moving the compacted drums therefrom; and chute means for directing said compacted drums into a water-containing tank.
Claim 11
Dependent Claim
45 words
A waste treatment apparatus as defined in claim 4, further comprising: drum receiving chamber means, disposed downstream of said compactor means, for receiving only partially compacted drums ejected from said compactor; and fourth conveyer means for moving said partially compacted drums away from said apparatus.
Claim 12
Dependent Claim
25 words
A waste treatment apparatus as defined in claim 13, further comprising piston-and-cylinder means for ejecting said only partially compacted cans onto said fourth conveyer means.
Claim 13
Dependent Claim
61 words
A waste treatment apparatus as defined in claim 11, wherein said third conveyer means comprises: can-pushing means engaging each can at a point above said shear means and passing above said shear means; and plate means, engaging each can at a point below said shear means and passing below said shear means, for pushing the sheared-off lid into a discharge chute.
Claim 14
Dependent Claim
22 words
A waste treatment apparatus as defined in claim 3, wherein: said shear means is movable to shear the lids of said drums.
