Some embodiments relate to a filtering sector for a filtering disc of a rotary filter, which includes: a structural element made up of a ribbed inner draining medium and a frame that surrounds the draining medium, which is provided with a connecting tube; and a filtering fabric that covers the structural element, wherein the structural element has a thickness which increases progressively towards the connecting tube and in that the draining medium is made up of a single sheet. The draining medium is made up of a single ribbed sheet provided with an alternation of channels, the depth of which increases as it gets closer to the mouth of the tube of the medium.
The filter (1) with vertical plates (2) according to the invention comprises plates (2) each comprising a nozzle (200) connected to an external manifold (5, 50, 51, 52), the said filter (1) is characterized in that it comprises at least two external manifolds (5, 50, 51, 52) and in that, for all the plates (2), two plates (2) which are adjacent are connected to two different external manifolds (5, 50, 51, 52). By not stripping two adjacent plates (2) at the same time, only one of the two filter cakes (6) facing one another is detached, rather than both. In this way it is possible to reduce the space left between the plates (2) without the risk of causing blockages fatal to the operation of the filter (1) as the filter cakes (6) drop off. This makes it possible to increase the number of plates (2) in the filter (1).

By not opening two adjacent plates (2) at the same time, only one of the two cakes (6) facing each other is detached, instead of the two. The construction of these plates (2) allows a slight swelling of the cloth (221) during plate opening and therefore limited movement of the cake (6). This allows the space provided between the plates (2) to be reduced without a risk of clogging that will prevent the filter (1) from functioning when the cakes (6) fall and without a risk of the removed cakes (6) being pressed against the plates (2) that are filtering. This makes it possible to increase the number of plates (2) in the filter (1).
