Abstract:

A paper machine includes a traveling belt for carrying a fiber web, and a cutting device disposed below the belt for cutting the fiber web into smaller pieces. The cutting device has an inlet and an outlet. A guiding device guides the fiber web from the belt to the inlet of the cutting device. A pulper is connected with the outlet of the cutting device for receiving the smaller pieces of fiber web from the cutting device. The traveling belt may be in the form of, e. g. , a wire, felt or water impervious belt. The cutting device may be in the form of, e. g. , a shredder, fluffer, water jet cutter, laser cutter and/or roll cutter.

Abstract:

A washing system for washing a fiber suspension associated with a fiber stock preparation system, includes a plurality of rolls and a porous fabric carried by the plurality of rolls in a closed loop. The closed loop includes a lower run defining a washing zone, with the porous fabric moving in a running direction through the washing zone. The porous fabric has an upper surface in the washing zone which carries the fiber suspension thereon. A headbox is positioned with the closed loop and above the porous fabric at an upstream end of the washing zone. The headbox discharges a fiber suspension to be washed onto the upper surface of the porous fabric. An accept removal device is positioned within the closed loop and above the porous fabric at a downstream end of the washing zone. A plurality of showers, each having an inlet, are positioned within the closed loop and above the porous fabric in the washing zone between the headbox and accept removal device. A plurality of dewatering elements are positioned below the fabric in the washing zone.

US Classification:

162 9, 162 57, 1621812, 162182, 162183

Abstract:

An apparatus for continuously loading fibers in a fiber suspension with a chemical compound includes a deflocculating vessel having an interior chamber, a fluid inlet connected with the interior chamber, a fluid outlet connected with the interior chamber, and a high shear imparting device disposed within the interior chamber for imparting high shear forces to and thereby deflocculating the fiber suspension. A mixing container has an interior compartment, a fluid inlet connected with both the interior compartment and the fluid outlet of the deflocculating vessel, a fluid outlet connected with the interior compartment, and a low shear imparting device within the interior compartment for imparting low shear forces to the fiber suspension. A gas supply is connected with the interior chamber of the deflocculating vessel and/or the interior compartment of the mixing container. The gas supply is configured for supplying a gas to and pressurizing each of the deflocculating vessel and the mixing container.
