Cylindrical wall for filtering solid particles in a fluid

A cylindrical wall for filtering solid particles in a fluid, through which this fluid is likely to circulate, this wall comprising:

• a perforated cylinder extending in a longitudinal direction, the cylinder being produced from at least one perforated plate,
• a grating assembly, of generally cylindrical form, intended to be in contact with the solid particles, the grating assembly and the perforated cylinder being concentric, the grating assembly comprising at least one grating element, the grating element comprising a plurality of wires each extending in the longitudinal direction, and
• means for assembling the at least one grating element so as to form the grating assembly of generally cylindrical form, the assembly means being arranged to ensure fixing of the at least one grating element on the perforated plate that can be dismantled.
