A horizontal leaf filter that discharges cakes as slurries
The basic filtration system is identical to the CFR Type. This model discharges the filtered cake as slurry after spraying the cake or rotating it in liquid.
This model type can recover filtered cake as slurries and also filter residual liquids.
Filtered cake is automatically discharged as slurry. The lower section of the vessel features a mirror plate with a slurry discharge outlet.
A fully automatic filter that can discharge cake as slurry
The filtration system is completely identical to the CFR Type. However, the CFA Type has the ability to discharge the filtered cake as a reslurry by spraying the cake or rotating it in liquid. This capability is beneficial in cases where it is more convenient to handle the filtered cake in slurry form in subsequent processes.
Structure
As with the CFR Type, which is IHI's standard model, numerous leaves are attached to the shaft inside its vessel. The CFA Type is a vertical cylindrical body with the upper casing equipped with a mirror plate on which a drive unit is mounted. The lower casing also features a mirror plate fitted with a slurry outlet.
