Abstract
A filtering body, in particular for a rotary separator, which extends about an axis, has two opposite axial faces and is provided with a filtering net constituted by filaments defining a plurality of pores between them and with a frame, which is defined by non-porous solid elements, supports the filtering net and is made in one piece with the filtering net; at least some of the filaments of the filtering net extend from one of the axial faces along respective longitudinal axes, which are parallel.
Claims10
A filtering body, extending about an axis of rotation and having a first axial face and a second axial face opposite to said first axial face, the filtering body comprising:
- a filtering net formed by a plurality of filaments that define a plurality of pores therebetween;
- a frame defined by non-porous solid elements, said frame and said filtering net extending about said axis of rotation forming an inner radial surface facing said axis of rotation and an outer radial surface opposite to said inner radial surface, and said inner radial surface being connected to said outer radial surface by said first axial face and said second axial face;
- wherein, when considering diametrical sections of said filtering body, at least some of said plurality of filaments extend from said first axial face up to said second axial face along respective longitudinal axes that are parallel, and wherein said longitudinal axes form an inclination with respect to said axis of rotation,
- wherein said frame and said filtering net are formed in one piece in an additive manufacturing technique.
A filtering body, extending about an axis and having a first axial face and a second axial face opposite to said first axial face, the filtering body comprising:
- a filtering net formed by a plurality of filaments that define a plurality of pores therebetween;
- a frame defined by non-porous solid elements, said frame for supporting said filtering net and made in one piece with said filtering net;
- wherein, when considering diametrical sections of said filtering body, at least some of said plurality of filaments extend from said first axial face up to said second axial face along respective longitudinal axes, which are parallel, and
- wherein said longitudinal axes form an inclination with respect to said axis of rotation,
- wherein said frame comprises a plurality of beams that extend in a circumferential or tangential direction with respect to said axis of rotation and support at least some of said plurality of filaments,
- wherein said plurality of beams are arranged substantially along said first and second axial faces and support the ends of said filaments,
- wherein said plurality of beams have the same cross-section, which is elongated parallel to a direction having a first inclination angle of between approximately 0° and 75° with respect to said axis, when considering any diametrical section plane,
- wherein each of said plurality of beams has two faces substantially parallel to said direction, in said diametrical section plane, wherein each of said plurality of beams supports the ends of three series of filaments, and wherein two of said three series of filaments are supported by said two faces with the other of said series of three filaments being substantially aligned with said beam.
