Abstract
Abstract A hydropulper having spiral structure for feeding into a pulping region and also for classifying, with the use of a self-contained revolving rake structure, primary materials found in household garbage and municipal waste. A vibrating screen structure is used in connection with the rake for separating water and pulp contained therein from floatables such as plastics, rubber and wood. Non-ferrous metals, rock, sand, glass, and so forth, are conveyed upwardly, underneath and past a rake area partition means, so as to be deposited onto conveyor structure. The input pulping mechanism is constructed for ease of revolving drum pulper structure removal, cleaning and maintenance. Valve means control water level for a variety of purposes. The rake structure is preferably inclined and also cam or otherwise elevated proximate the discharge region.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
162 words
Hydropulper and classifying equipment including, in combination: an outer cylinder having a feed hopper, an inner cylinder revolvably mounted within said outer cylinder and communicating with said hopper, said inner cylinder including interior pulping projections, means for rotating said inner cylinder coupled thereto, a tank integral with said outer cylinder, said tank including an inclined trough, an auger journaled for disposition within said trough and extending in an upper end upwardly therefrom, means for rotating said auger coupled thereto, conveyor means disposed beneath said upper end of said auger for receiving contents expelled thereat, revolvable rake means essentially horizontally disposed within said tank, said tank having a side discharge opening proximate the travel path of said rake means, a water-pulp receiving trough operatively disposed proximate said discharge opening, vibrating screen means positioned above said water-pulp receiving trough and proximate said discharge opening, and conveyor means disposed at a lower level than and proximate said vibrating screen means for receiving materials vibrated thereover.
Claim 2
Dependent Claim
162 words
Hydropulper and classifying equipment including, in combination: an outer cylinder having a feed hopper, an inner cylinder revolvably mounted within said outer cylinder and communicating with said hopper, said inner cylinder including interior pulping projections, means for rotating said inner cylinder coupled thereto, a tank integral with said outer cylinder, said tank including an inclined trough, an auger journaled for disposition within said trough and extending in an upper end upwardly therefrom, means for rotating said auger coupled thereto, conveyor means disposed beneath said upper end of said auger for receiving contents expelled thereat, revolvable rake means essentially horizontally disposed within said tank, said tank having a side discharge opening proximate the travel path of said rake means, a water-pulp receiving trough operatively disposed proximate said discharge opening, vibrating screen means positioned above said water-pulp receiving trough and proximate said discharge opening, and conveyor means disposed at a lower level than and proximate said vibrating screen means for receiving materials vibrated thereover.
Claim 3
Dependent Claim
21 words
The equipment of claim 1 wherein said tank includes a drain, and valve means for selectively opening said drain coupled thereto.
Claim 4
Dependent Claim
35 words
The equipment of claim 1 wherein said inner cylinder includes a central shaft journalled at opposite ends, and auger means disposed upon said shaft and positioned below, proximate, and in communication with said hopper means.
Claim 5
Dependent Claim
44 words
The equipment of claim 1 wherein said rake means is inclined for scooping upwardly in the direction of rake travel, and means cooperable with said rake means for elevating said rake means when the latter advances at its respective extremity toward said discharge opening.
Claim 6
Dependent Claim
73 words
The equipment of claim 1 wherein said equipment includes motor means for revolving said rake means and having a shaft, said rake means comprising a pair of rakes pivoted about respective, offset transverse axes to said shaft, and a cam plate fixedly disposed within said tank and having a cam rise disposed proximate said discharge opening and engagable by said rakes, for lifting the latter as the same respectively approach said discharge opening.
Claim 7
Dependent Claim
29 words
The equipment of claim 1 wherein said tank has an arcuate partition defining a travel path lateral extremity for said rake means, said inclined auger passing underneath said partition.
Claim 8
Dependent Claim
13 words
The equipment of claim 6 wherein said rake means include resilient, wiper ends.
Claim 9
Dependent Claim
105 words
Hydropulper and classifying equipment including, in combination, means for receiving non-sewage waste materials, including pulpable products, and for pulping the same in an aqueous environment; rake means, centrally revolvable about a vertical axis, for routing puLped materials into receiving structure; means for advancing heavier-than-water materials gradually upwardly, underneath said routing means, to a discharge end; fixed, horizontally arcuate, vertical partition means supported above and depending into said receiving means, above said advancing means and between said routing means and said discharge end, and positioned proximate said rake means along its revolvement path, for preventing so-pulped products from flowing horizontally toward and into said advancing means.
Claim 10
Dependent Claim
105 words
Hydropulper and classifying equipment including, in combination, means for receiving non-sewage waste materials, including pulpable products, and for pulping the same in an aqueous environment; rake means, centrally revolvable about a vertical axis, for routing puLped materials into receiving structure; means for advancing heavier-than-water materials gradually upwardly, underneath said routing means, to a discharge end; fixed, horizontally arcuate, vertical partition means supported above and depending into said receiving means, above said advancing means and between said routing means and said discharge end, and positioned proximate said rake means along its revolvement path, for preventing so-pulped products from flowing horizontally toward and into said advancing means.
Claim 11
Dependent Claim
161 words
Hydropulper and classifying equipment including, in combination: an outer cylinder having a feed hopper, an inner cylinder revolvably mounted within said outer cylinder and communicating with said hopper, said inner cylinder including interior pulping projections, means for rotating said inner cylinder coupled thereto, a tank integral with said outer cylinder, said tank including an inclined trough, an auger journaled for disposition within said trough and extending in an upper end upwardly therefrom, means for rotating said auger coupled thereto, conveyor means disposed beneath said upper end of said auger for receiving contents expelled thereat, revolvable rake means cooperatively disposed within said tank, said tank having a side discharge opening proximate the travel path of said rake means, a water-pulp receiving trough operatively disposed proximate said discharge opening, vibrating screen means positioned above said water-pulp receiving trough and proximate said discharge opening, and conveyor means disposed at a lower level than and proximate said vibrating screen means for receiving materials vibrated thereover.
