Abstract
In a sector-shaped screen segment for disk filters or thickeners with a folded screen for thickening fiber suspensions comprising a frame, two screen carriers and a screen resting on the outer sides of the screen carriers, manufacture is rendered simpler and less expensive by the frame and the screen carriers forming an integral molded part in which the screen is embedded in the molding process.
Claims13
A screen segment for a rotary disk filter having an axis of rotation said screen segment comprising a frame means having opposed surfaces and substantially defining the outer periphery of said screen segment and extending substantially perpendicularly to the axis of rotation said frame means including radially spaced outer and inner legs as well as lateral legs connected to opposed ends of said outer leg and extending toward said axis of rotation and connected to opposed ends of said inner leg;
- screen carrier means having opposed supporting surfaces and encompassed by and joined to said frame means;
- spaced screens defining opposed outer main surfaces of said screen segment and supportably mounted on the opposed surfaces of said screen carrier means and said frame means;
- said screen carrier means and said frame means comprising molded elements in which said screens are supportably embedded.
A sector-shaped screen segment for a rotary disk filter having an axis of rotation, said screen segment comprising a frame extending substantially perpendicularly to the axis of rotation and having an outer leg radially spaced from the axis of rotation and a lateral leg connected to each of the ends of said outer leg, said lateral legs converging toward said axis of rotation;
- screen carrier means attached to at least two of said legs, said screen carrier means having screen supporting elements and openings therebetween;
- and two axially spaced filter screen means defining two opposed main surfaces of the screen segment, said filter screen means being supported by said screen supporting elements;
- said screen carrier means being in the form of at least one molded part in which said filter screen means are embedded.
