Abstract
An apparatus is presented for effectively sorting and disposing of waste. Waste is sorted into three or more groups enabling post treatment or reutilization of the sorted waste with less possibility of environmental contamination. The apparatus comprises mainly a drum having a plurality of screen means and a plurality of rotatable reducing means, each of the reducing means facing a corresponding screen means, respectively and being driven at a properly selected speed depending on the constituents of the waste and the mesh size of the opposing screen.
Claims5
An apparatus for disposing of and sorting waste, comprising:
- a hopper for receiving waste;
- a cylindrical drum communicating with said hopper and having a discharge opening, said drum being provided with a first screen and a second screen axially disposed;
- and
- a first and second reducing means in opposed relation to said first and second screens, respectively;
- supporting means for rotatably supporting said first and second reducing means so as to rotate said reducing means within said drum, a first portion of said supporting means supporting said first reducing means being coaxial with a second portion of said supporting means supporting said second reducing means,
- driving means for driving said first and second reducing means at an independent rotational speed, respectively through said supporting means;
- a first outer cylinder and a second outer cylinder disposed around said first and second screens, respectively, said first and second outer cylinders being provided witha discharge opening, respectively, so as to discharge the sorted waste received therein which has passed through the corresponding screen.
An apparatus for disposing of and sorting waste, comprising:
- a hopper for receiving waste;
- a cylindrical drum with said hopper and having a discharge opening at a position opposite said hopper, said drum being provided with a first screen and a second screen axially disposed and the mesh size of said first screen being relatively small compared to that of said second screen;
- a first shaft and a second shaft arranged coaxially with each other, said shafts centrally extending through said drum and being rotatably supported;
- a first size reducing means mounted on said first shaft in opposed relation to said first screen within said drum;
- a second size reducing means mounted on said second shaft in opposed relation to said second screen within said drum;
- a first driving means coupled to said first shaft to rotate the same;
- a second driving means coupled to said second shaft so as to rotate said second shaft independently from said first shaft and at a speed different from that of said first shaft;
- and
- a first outer cylinder and aa second outer cylinder disposed around said first and second screens, respectively, said first and said second cylinders being provided with a discharge opening, respectively, so as to discharge the sorted waste received therein which has passed through the corresponding screen.
