These industries benefit from semi automation by increasing batch efficiency, protecting finished products, and making the work environment safer for operators.
The semi automatic filter press follows the standard principles of pressure filtration while adding layers of control and automation to enhance operator efficiency. It is especially effective in processes that require consistent batch filtration with clean discharge and minimal downtime.
The slurry is pumped into the chambers using an external pump. Automatic inlet valves control the flow and shut off once the chamber is full.
The operator closes the plates using a hydraulic system. Once sealed, the filtration process begins.
Liquid passes through the filter cloths mounted on each plate. The solids are retained and form cakes between the plates.
As filtration occurs, any minor leakage due to the cloth capillary action is caught by the bomb door drip tray system. This prevents contamination of discharged cakes and maintains clean floors.
After filtration, plates are automatically or semi-automatically shifted. Filter cakes fall onto a rubber belt conveyor, which carries them into a hopper for collection.
Operators can use the individual plate transport system to open specific plates for cleaning or replacement before starting the next cycle.
