LIQUID FILTRATION INSTALLATION, FIXING DEVICE, FILTER ENVIRONMENT ELEMENT, METHOD OF OPERATION AND METHOD OF MAINTENANCE OF SUCH INSTALLATION

摘要

The invention relates to an apparatus (1) for filtering a liquid containing a filter chamber (3), discharged by gravity and which is stationary, at least during discharge of the filter cake. The installation also contains a filter medium element (4), comprising a sleeve (4a) having, during operation, a vertically closed periphery extending inside the space with the filter chamber (3) limited at least in the transverse direction, as well as a loading hole (4b) ) and discharge opening (4c). There is also a drainage means (2a) configured to receive the filtrate from the filter chamber (3) through the filter medium element (4), as well as a compression device (2b) configured to apply a compressive force to the filter chamber (3) outside the element ( 4) filter medium. The invention also proposes a fixing device (5), an element (4) of a filter medium, as well as an operation method and a maintenance method.
