The DCV bar screen is a mechanical fully automatic screen used for liquid/solid separation in the pretreatment stage of wastewater treatment plants, pumping station …
ADVANTAGES
- Automatic operation
- Small space constraints
- Material : stainless steel 304L or 316L
- Fineness of screening : 8 mm minimum
OPERATING PRINCIPLE
This screen is operated by a single cable driven by one gearmotor. It starts and stops according to the effluent upstream level (level sensor) or by timer clock.
When starting, the rake leaves its upper position to move downwards to the bottom of the screen. The cable unrolls from the drum. When reaching the bottom of the channel, the rake stops.
When the slack cable detection device is actuated (inductive sensor), the cable drive motor direction is inverted in order to lift back the rake.
Rake closes and starts moving upwards, carrying the waste trapped on the grid to the point of discharge. Waste screenings will then fall down either into a container, a screw conveyor or a screw compactor for transport.
The operating cycle will start again according to preset settings
