Design Focus
The drum filters are
characterised by following features:
-
filter cells are accessible and can be easily cleaned
(also with online cleaning if required)
-
on small filters, the filter cells can be exchangeable so as to reduce the filter down time for cloth exchange
-
the filter cells can consist of exchangeable plates for ease of maintenance
-
the head valve is designed to pre-separate liquid and air and to offer only a low flow resistance
-
all types of drum filter are adapted to high rotation speeds
-
the drum filters for food and pharmaceutical industry have a simple design for an efficient self cleaning
-
the cake discharge is adapted to the product filtered
-
the filtrate pipes are connected to both leading and tailing edge of each cell to ensure a complete emptying of the cells before cake discharge
-
the slurry level in the trough controls the filter speed for a constant cake moisture and no overflow
-
the overflow is sized to contain all the slurry fed without leakage out of the filter
-
the drain valves are sized to allow a really quick emptying of the trough at shut down so as to avoid sedimentation within the trough if the filter has to be stopped
-
the agitator can be easily removed without dismantling of the drum for reducing the maintenance work
-
the process angles are individually adjusted to each process and client's requirements so as to get the highest possible throughput for the concerned product
-
the filter operation is automatically operated from the start to the stop with a proven interlock system for a safe operation
