A modular table filter for a circular horizontal rotating table filter includes a number of sections which may be assembled on the support frame thereof. The sections are annular-sector-shaped and, when assembled, form an annulus on the table filter. Each section, in turn, may be broken down into an outer subsection and an inner subsection. Filtration fabric, or textile, may be placed on top of the outer subsection, and secured therein by the inner subsection, which is designed to lock thereinto. Alternatively, each section may be an integral annular-sector-shaped frame having a peripheral groove or channel. Filtration textile may be placed on top of the frame, and over the groove or channel, and wedges driven thereinto to hold the fabric tautly across the frame. The modular table filter greatly simplifies the replacement of the filtration fabric, as the sections holding fabric needing replacement may be removed easily and replaced by ones having fresh filtration textiles without the need for isolating the table filter for an inordinately long time.
A modular table filter, said modular table filter having the form of an annulus assembled from a plurality of annular-sector-shaped sections, each of said sections comprising a filtration textile and means for holding said filtration textile tautly thereacross, wherein each of said annular-sector-shaped sections comprises an outer subsection and an inner subsection fitting therewithin, each outer subsection having a first radial member and a second radial member, said first radial member and said second radial member having an inner surface within said annular-sector-shaped section and an outer surface without said annular-sector-shaped section, said inner surface having a ledge, so that said inner subsection may be supported within said outer subsection between said first radial member and said second radial member thereof, said ledge being provided with fastening means to secure said inner subsection within said outer subsection, said inner subsection also having a first radial member and a second radial member, said first radial member and said second radial member having outer surfaces with fastening means engageable with said inner surface of said first and second radial members of said outer subsection, and said outer surfaces of said first radial member and said second radial member of said outer subsection having fastening means for connection with second and first radial members of outer subsections of adjacent annular-sector-shaped sections, respectively, to complete said annulus, and wherein said means for holding said filtration textile tautly across said annular-sector-shaped sections is the fastening of said inner subsection within said outer subsection over said filtration textile.
A modular table filter, said modular table filter having the form of an annulus assembled from a plurality of annular-sector-shaped sections, each of said sections comprising a filtration textile and means for holding said filtration textile tautly thereacross, wherein each of said annular-sector-shaped sections comprises an annular-sector-shaped frame, said frame having a peripheral channel with parallel walls extending thereabout on a surface thereof, and wherein said means for holding said filtration textile tautly across said annular-sector-shaped sections is at least one wedge, placed above said filtration textile and driven into said channel.
