Combined water flushing vehicle, for cleaning tanks and sewers and the like, has a waste water recycling system with a screening chamber and grid, to recycle its own cleaning water without drawing on public supplies

摘要

The screening system, in a waste water recycling circuit in a combined water flushing vehicle, has a sludge tank (2) which can be opened at the bottom (3). A recirculating pump (5) is at the base of the tank. A housing at the opening base defines a screening chamber (7) with a fixed grid, and cleaners (16) to keep the grid free from clogging. The screening system, in a waste water recycling circuit in a combined water flushing vehicle, has a sludge tank (2) which can be opened at the bottom (3). A recirculating pump (5) is at the base of the tank. A housing at the opening base defines a screening chamber (7) with a fixed grid, and cleaners (16) to keep the grid free from clogging. An inner cover (8) can be moved between a sealed and closed position and an outflow opening (12) linked to a volume capacity (13). An evacuation piping (14) allows the pump to transfer the waste water held in the sludge tank into the recycling circuit after passing through the grid.
