Plate filter press

DETAILED DESCRIPTION It is therefore an object of the present invention to provide a filter press which is suitable for pressures of at least about 25 bars to 120 bars and can simultaneously perform the functions of mechanical phase separation, temperature adjustment of the suspension, both heating and cooling, as well as using temperature adjustment to clean the suspension chamber and the filter medium, while avoiding the above-described drawbacks of the prior art filter presses.
The present invention solves these problems by a plate filter press for the mechanical separation of solids from a liquid suspension.
The plate filter press is made of a plurality of vertical membrane plates and filter plates, the membrane plates and filter plates being alternately arranged one after the other.
When the plate filter press is assembled, the space between the membrane plates and filter plates defines a filter chamber, which can be opened by moving the plates apart.
A liquid impermeable and flexible membrane is positioned in the filter chamber and is sealed to the periphery of the membrane plate.
The space between the membrane and the membrane plate defines a pressure medium chamber for receiving pressure medium.
The space between the membrane and the filter plate defines a suspension chamber for receiving the suspension.
Finally, a woven metal fabric filter is positioned on each side of the filter plate.
Both the filter plates and the woven metal fabric filters are planar.
Liquid from the suspension is discharged through the woven metal fabric filter toward the interior of the filter plates.
