Title (EN) CANDLE FILTER SUPPORT AND PLATE ASSEMBLY FOR POLYMER MELTS
(FR) SUPPORT POUR FILTRE-BOUGIE ET ENSEMBLE PLAQUE POUR MATIÈRES POLYMÈRES FONDUES
Abstract:
(EN) A polymer melt candle filter having a support which comprises a hollow cylindrical body (101) defined by a first end (102), a second end (103), and a cylinder wall (104) having a first end portion (105) and a second end portion (106). The first end portion (105) includes a screw thread (107) on its outside surface and optionally a hex fitting (203) on its inside surface for receiving a hex wrench. The second end portion (106) includes a plurality of holes (108) in the cylinder wall (104). The area of the openings (301, 302) of the holes (108) on the outside surface of the cylinder wall (104) may be larger than the area of the openings (301, 302) of the corresponding holes (108) on the inside surface of the cylinder wall (104). The shape of the openings (301, 302) of the holes (108) on the outside surface may be non-circular. A polymer melt filter plate assembly which comprises (a) a support plate (1604) comprising a plurality of threaded holes (1610); (b) at least one filter which is screwed into at least one of the threaded holes (1610) via the screw thread (107) on the outside surface of the first end portion (105) of the filter support (100, 1605); (c) a tie rod (1606) with (i) a first end extending through a hole (1005) in a cone insert (1619, 701) and a cap (1001, 1611) located at the second end (103) of the filter support (100, 1605), and (ii) a second end extending through a threated hole (1610) in the support plate (1604); and (d) a cross bar (1607) which is attached to the second end of the tie rod (1606) for holding the support plate (1604) inside a shaft (1601) of an apparatus for filtering a polymer melt.
(FR) L'invention concerne un filtre-bougie pour matière polymère fondue comprenant un support constitué d'un corps cylindrique creux (101) défini par une première extrémité (102, 103), une seconde extrémité (102, 103), et une paroi de cylindre (104) ayant une première partie d'extrémité (103, 105, 106) et une seconde partie d'extrémité (103, 105, 106). La première partie d'extrémité (103, 105, 106) comprend un filetage (107) sur sa surface extérieure et éventuellement un raccord hexagonal (203) sur sa surface intérieure pour recevoir une clé hexagonale. La seconde partie d'extrémité (103, 105, 106) comprend une pluralité de trous (108) ménagés dans la paroi de cylindre (104). La surface des ouvertures (301, 302) des trous (108) sur la surface extérieure de la paroi de cylindre (104) peut être supérieure à la surface des ouvertures (301, 302) des trous correspondants (108) sur la surface intérieure de la paroi de cylindre (104). La forme des ouvertures (301, 302) des trous (108) sur la surface extérieure peut être non circulaire. Un ensemble plaque à filtre pour matière polymère fondue (705) est en outre décrit, ledit ensemble comprenant (a) une plaque de support (1604) comprenant une pluralité de trous taraudés (1610, 1614); (b) au moins un filtre qui est vissé dans au moins un des trous taraudés (1610, 1614) par l'intermédiaire du filetage (107) sur la surface extérieure de la première partie d'extrémité (103, 105, 106) du support de filtre (100, 1605); (c) un tirant (1606) ayant (i) une première extrémité (102, 103) s'étendant par un trou (1005) dans un insert de cône (1619, 701) et un capuchon (1001, 1611) situé à la seconde extrémité (102, 103) du support de filtre (100, 1605), et (ii) une seconde extrémité (102, 103) s'étendant par un trou fileté (1614) dans la plaque de support (1604); et (d) une barre transversale (1607) fixée à la seconde extrémité (102, 103) du tirant (1606) pour maintenir la plaque de support (1604) à l'intérieur d'un arbre (1601) d'un appareil pour filtrer une matière polymère fondue.
