Filter with closely-spaced vertical plates

Abstract

The filter (1) according to the invention with vertical plates (2) includes plates (2) each including a tube (200) connected to an external manifold (5, 50, 51, 52), and said filter (1) is characterized in that it includes at least two external manifolds (5, 50, 51, 52), in that, for all the plates (2), two adjacent plates (2) are connected to two different external manifolds (5, 50, 51, 52) and in that each plate (2) includes at least one filter element (22), each filter element (22) being constituted of at least two drains (220) and a cloth (221), the (221) having compartments (222) in each of which a drain (220) is inserted. By not discharging two adjacent plates (2) at the same time, only one of the two facing cakes (6) is detached rather than both of them. The construction of these plates (2) enables low inflation of the cloth (221) during discharge and therefore limited movement of the cake (6). It is therefore possible to reduce the space provided between the plates (2) with no risk of causing jams fatal to the operation of the filter (1) when the cakes (6) fall off and with no risk of pressing the discharged cakes (6) onto the plates (2) during filtration. This makes it possible to increase the number of plates (2) in the filter (1).
