Title: Arrangement for the removal of waste material
IPC: B65F9/00
Filed: 1972-02-15
Abstract: An arrangement for the removal of waste material is disclosed in which waste material is loaded into cylindrical containers at each of a number of filling stations. After being filled, the containers are sealed and transported by lorry, rail or water to a discharge station at which the material in the containers is discharged into a suitable processing plant. Each container is provided with a hatchway engageable with filling means at a filling station, whilst the container is rotated about its longitudinal axis to cause waste material introduced into the container to be compressed by interaction with a helical blade which projects from the peripheral wall towards the interior of the cylindrical container. At the discharge station, the waste material is discharged from the cylindrical container whilst the container rotates in a direction opposite to its direction of rotation of the filling station. At the filling station, the container is mounted on a mono-rail, along which it is propelled to cause its hatchway to engage means for introducing waste material into the container. Each filling station is provided with rails extending transversely of the mono-rail and each container is rolled by a winch across these rails for loading on to a lorry or barge for transporting it to the discharge station. At the discharge station, an arrangement analogous to that which has been described at the filling station is provided, except that means for receiving waste material from the containers replaces the means for introducing the waste material therein. The filled containers, after being sealed, may be arranged to be sufficiently buoyant to float and may therefore be towed along waterways to a discharge station, such as a remote off-shore island.
