Patent number: 5638960Abstract: A screen for sorting fiber suspensions comprising a plurality of screen perforations having a hole type design, with each screen perforation having an ingress area and an egress area for the flow of fiber suspensions, wherein the ingress area is rounded to a convex curvature. The convex curvature increases the velocity of the fiber suspensions through the screen thereby reducing clogging of the suspensions in the screen and increasing the throughput and the sorting integrity of the screen. Alternative embodiments of the screen include an area of constant cross section connecting the ingress area and the egress area, and transitional edges formed in the transition areas.Type: GrantFiled: March 31, 1995Date of Patent: June 17, 1997Assignee: J.M.

Patent number: 5492225Abstract: A sorter with a symmetric screen which is arranged concentrically in an essentially symmetric housing, and in the interior of which there is contained a concentric rotor drum that features on its periphery sorting elements sweeping across the screen, circulating at least parts of the suspension being sorted around the walls of the drum. The sorting elements are of a design such that they will generate a vortex flow of the suspension in the housing. The housing features at its periphery at least one removal duct for heavy contaminants and, in one of its end walls, a central lightweight dirt drain. The housing end wall that features the lightweight dirt drain has, in the direction away from the screen and the rotor drum, from radially outside to radially inside, a diameter that tapers in conic fashion by maximally 11 mm per each 3 mm of axial housing length, and minimally by 2 mm per each 3 mm of axial housing length.Type: GrantFiled: August 3, 1994Date of Patent: February 20, 1996Assignee: J.

Patent number: 5045183Abstract: The rotor of a sorter has a circumference which, in cross section perpendicular to the rotor axis of rotation, is essentially composed of circular arcs. Depending on sorter size, the number of circular arcs amounts to between two and eight. The eccentricity of the circular arcs relative to their center, based on the rotor axis of rotation, amounts to preferably between 4 and 10 mm. This makes it possible to obtain slight rotor stresses at a good sorting efficacy, preferably also with a mean substance density of more than 3% of fiber suspensions. The difference between the smallest and greatest rotor spacing e=f.sub.max -f.sub.min amounts to maximally 60 mm, preferably 20 mm.Type: GrantFiled: July 17, 1990Date of Patent: September 3, 1991Assignee: J.
