Device for separating a heterogeneous mass of solid material into fractions

Claim 1

A device for separating high density and low density constituents from a heterogeneous mass of solid material in household, industrial, and other similar waste, in which the material is first dried and then separated into said constitutents, comprising a trough-shaped container having a material charging end for receiving the mass, a vibrator connected to said container to produce vibrations causing the segregation of said high density constituents downwards and said low density constituents upwards, said container having a lower zone and an upper zone; take-off devices in both said lower zone and upper zone, and an intermediate take-off device arranged between the take-off devices in said upper and lower zones, said take-off devices being operable for removing the separated constituents from the container, said intermediate take-off device being connected to a material charging device which leads back to the upper zone of the container, said take-off devices in said upper and lower zones and said intermediate take-off device each having a take-off opening and a conveyor means subsequent thereto, each of said take-off devices further constituting pipes such that at least one of the take-off openings is arranged in a wall of the container, wherein the conveyor means of the take-off device in said upper zone includes an exhaust device connected thereto, the take-off pipe of said device in said upper zone projects into the container from above, and further wherein the take-off pipe of said device in said upper zone is inclined towards the material charging end of said container and the inclination is adjustable to ensure that the take-off device in the upper zone removes only the low density constitutents.

Claim 2

A device for separating high density and low density constituents from a heterogeneous mass of solid material in household, industrial, and other similar waste, in which the material is first dried and then separated into said constitutents, comprising a trough-shaped container having a material charging end for receiving the mass, a vibrator connected to said container to produce vibrations causing the segregation of said high density constituents downwards and said low density constituents upwards, said container having a lower zone and an upper zone; take-off devices in both said lower zone and upper zone, and an intermediate take-off device arranged between the take-off devices in said upper and lower zones, said take-off devices being operable for removing the separated constituents from the container, said intermediate take-off device being connected to a material charging device which leads back to the upper zone of the container, said take-off devices in said upper and lower zones and said intermediate take-off device each having a take-off opening and a conveyor means subsequent thereto, each of said take-off devices further constituting pipes such that at least one of the take-off openings is arranged in a wall of the container, wherein the conveyor means of the take-off device in said upper zone includes an exhaust device connected thereto, the take-off pipe of said device in said upper zone projects into the container from above, and further wherein the take-off pipe of said device in said upper zone is inclined towards the material charging end of said container and the inclination is adjustable to ensure that the take-off device in the upper zone removes only the low density constitutents.
