Strainer drum for pulp and the like

A strainer drum for straining pulp and the like, comprising a substantially circular cylindrical mantle having a longitudinal axis and formed by strainer elements provided with strainer openings, a pair of gables forming opposite ends of the drum and between which the strainer elements are held together to form said mantle, said elements having inter-abutting edges to form a circular series of said elements as viewed in a plane transverse to said axis, there being a plurality of said circular series interposed between said gables, first means releasably interlocking said abutting edges in each circular series to prevent radial movement of said elements, each pair of adjacent circular series having interengaging surfaces, and second means releasably interlocking said interengaging surfaces to interconnect the strainer elements of each circular series in said adjacent pair.
