摘要： A method for dewatering a fibrous material web, wherein fibrous material is applied via a headbox on at least one wire and is subsequently dewatered in order to form a fibrous material web. Following the wire section, the resulting fibrous material web is dewatered by several presses, wherein the first press through which the fibrous material web is guided following the headbox is equipped with a double nip. The first press is formed by a wire roll and two couch rolls which are each pressed against the wire roll for forming a nip. Also disclosed is a corresponding device for carrying out the method.

摘要： A double screen belt press for dewatering mixtures of fibrous material suspensions has a wedge compression zone comprising rolls and perforated plates supporting generally upper and lower screen belts. For dewatering mixtures of fibrous material suspensions having a high dry solids content, at least one sealed material feed empties into the wedge compression zone with a high pressure. A generally vertically gravity tower with an outlet port is provided to feed material into the entrance of the wedge compression zone above the lower screen belt and in front of the front roll supporting the upper screen belt. The outlet port area of the material feed is sealed on at least the side facing the lower screen belt and optionally on the side facing the upper screen belt and on the other side of the material feed facing away from the wedge compression zone between the material feed and the lower screen belt.

摘要： The invention relates to an apparatus or plant or arrangement for the treatment of a dilute suspension of fibers or layer of material passed between two endless foraminous belts or wires or the like conveying means, the forming fibrous board being made to pass between the foraminous belts along at least one container for a treatment medium and at least some of the treatment containers being provided with a wall having orifices on the side facing the fibrous board for generating a pressure difference on the same, but being otherwise closed against the environment, and/or at least some of the treatment containers closed against the environment having walls closed against the foraminous belts and thus against the fibrous board, but otherwise open towards the foraminous belts. According to the invention, a reduction of the energy requirement in the displacement washing of filter cakes is sought above all. This is achieved according to the invention in that in particular for countercurrent treatment, conveniently for countercurrent displacement washing, at least one treatment container arranged above the upper framinous belt, in particular in contact with said belt, is formed as a pressure container from which the treatment liquid is dispensed under superpressure to the foraminous belts or to the forming fibrous board or layer of material present therebetween, and further by providing for a pressureless collecting container or pressureless collecting containers to be provided opposite this or these pressure container(s) underneath the lower foraminous belt.

摘要： The invention relates to a method and device for the washing of a medium consistency fibrous slurry, especially a chemical pulp slurry in which the slurry is fed at an inclined angle onto a substantially horizontal portion of circulating filter belt, and then distributed over substantially the entire working width of the filter belt. The distributed slurry is then washed with a washing liquid under localized pressure to produce a slurry having a medium consistency range, i.e., about 8 to 15 percent. In order to increase the consistency to 20 to 40 weight percent, preferably about 30 to about 35 weight percent, the washed slurry is passed to a pressing zone.
