    摘要: Method and apparatus for removing impurities from a fibrous suspension. The method includes conducting a fibrous suspension stream into an inflow chamber of a pressurized screen, concentrating portions of the fibrous suspension stream to be removed in front of a screen basket, discharging the concentrated portions in an overflow stream, passing an other portion of the fibrous suspension stream through the pressurized screen as a throughput stream, and guiding gases out of a central region of the housing of the pressurized screen. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

    摘要: 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.

    摘要: Pressurized screen to remove contaminants from a contaminant-containing fibrous paper suspension. Pressurized screen includes a housing, a first screen element, essentially axially symmetric and rotatably mounted within housing, and a second screen element, which is essentially axially symmetric. First and second screen elements are successively arranged in suspension flow direction. At least one intake, coupled to housing, supplies suspension to housing, and at least one accepts outlet, coupled to housing, conveys a part of suspension that passes through the second screen element out of housing. At least one coarse reject outlet is located within housing to remove a part of suspension not passing through first screen element, and at least one fine reject outlet is located within housing to remove a part of suspension not passing through second screen element. First screen element includes conical shape with opening angle (&agr;) between about 10° and 170°.

    摘要: A pressure sorter for a suspension flow includes a cylindrical housing having at least one inlet opening and at least one outlet opening with a defined pressure drop therebetween. A rotationally symmetric screen basket defining an axis is disposed within the housing. The screen basket has a plurality of openings defining a total screen perforation passage area. The axis of the screen basket is positioned offset a distance of 6 to 12% of the diameter of the screen basket. The axis of the screen basket is disposed in a plane which extends through the housing axis and is perpendicular to the housing outlet opening. A rotor and suspension sorting space are disposed centrically within the screen basket. An accepts space is disposed radially outward of the screen basket between the screen basket and the housing. The accepts space has a cross section causing a pressure drop between the suspension sorting space and the accepts space resulting in a suspension flow through the screen openings having a maximum velocity of 2.5 m/s, and a deviation to higher suspension flow velocity values from an arithmetic mean value based on the total screen perforation passage area across the entire screen basket circumference amounting to a maximum of 25% of the mean value.

    摘要: 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.

    摘要: 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.
