Abstract
The present invention relates to a filter panel which is intended to be mounted in a drum filter, the filter panel comprising a peripheral frame to which a filter cloth is fixed, the frame being formed by two longitudinal members which are connected at each end by an end cross-member, characterized in that the filter panel comprises a lattice (R1) of crosspieces which connect the inner edges of the frame to one another, the lattice (R1) of crosspieces forming at least a first closed pattern (54) in the centre of the frame and comprising at least four diagonals which are inclined with respect to the longitudinal members and which extend from the first closed pattern to an inner edge of the frame.
Claims18
A rotary drum filter comprising:
- a filter panel including:
- a peripheral frame being formed from two longitudinal members which are connected at each end by an end cross-member;
- a lattice (R1) of crosspieces which connects inner edges of the peripheral frame to one another, the lattice (R1) of crosspieces forming at least a first closed pattern in the center of the peripheral frame and having at least four diagonals which are angled with respect to the longitudinal members and which extend from the first closed pattern to an inner edge of the peripheral frame, the lattice (R1) of crosspieces has at least two intermediate cross-members which are parallel to the end cross-members and which are arranged respectively on either side of the first closed pattern;
- and
- a filter cloth capable of capturing particles in a liquid flow, is fastened to one side of the peripheral frame and completely covers a corresponding side of the lattice (R1).
