    摘要: Method and flotation vessel for removing contaminants from aqueous fibrous suspension. Method includes damming up fibrous suspension at head level above base of flotation vessel, forming a bubble flow of gas bubbles rising counter to field of gravity in dammed up fibrous suspension, and guiding fibrous suspension crosswise to bubble flow, such that as contaminants are deposited on gas bubbles to form thickened flotation foam, fibrous suspension is cleaned. Method also includes discharging cleaned fibrous suspension as accepts, and discharging thickened flotation foam. A flow cross section of flotation vessel lying crosswise to bubble flow is straight on at least 80% of at least one side wall and a length of side wall is at least 1.5 times as great as that of an end wall. This abstract is neither intended to define invention disclosed in this specification nor intended to limit the scope of the invention in any way.

    摘要: The flotation apparatus removes ink- and contaminant particles from a fiber stock suspension which is produced during the preparation of waste paper. Admixing of air to the fiber stock suspension is accomplished in stepped diffusors. The fiber stock suspension admixed with air, prior to infeed into a flotation container, is guided through a deflection element effective as an impact mixer and followed by a mixing diffusor having a preferred flow direction. This flotation apparatus is especially suited for eliminating disturbing or spurious substances which are present throughout a relatively wide grain size spectrum. A particularly preferred construction uses one or more closed flotation containers, wherein the air effluxing from the flotation foam can be advantageously re-used for aeration of further infed fiber stock suspension.

    摘要: Process and apparatus for the separation of solid matter via flotation. The flotation process for the separation of solid matter from a suspension takes place via the utilization of centrifugal forces wherein the suspension is brought into rotation in a separating zone so that the floated components are particularly effectively routed to and concentrated at the center of the separating space, whereby, when viewed axially, floated components and the remaining portion of the suspension is guided in the same direction and out of the separating zone, with the avoidance of vortexes in the flow stream achieving particularly favorable separation effects. In addition, several apparatuses, for carrying out the process, are also set forth.
