The opening process of press filter from feeding to discharging is described briefly
Close all piping valves and continue to remove extrusion pressure.After opening the filter, the filter press is opened and the cake discharge is carried out.
Open the central blowback return valve, send compressed air, and clean the inlet channel. The time is set according to the experience and the setting time.
Start and close the filter press.Open the feed valve.Starting feed pump.Control feed pressure or time, or two at the same time, to the set value, stop feeding.Close feed valve.With diaphragm extrusion equipment, start the diaphragm extrusion pump, correctly open the valve of each extrusion system, control the extrusion pressure, and then stop the extrusion after the setting value.Slow release of extrusion pressure, generally to about 7bar, stop pressure release.
