Device for plate of disperser and method of grinding paper

FIELD: machine building.

SUBSTANCE: subassembly opposite discs or cones for disperser, wherein each disc or cone has plate or set of segments of plate with front surface on each plate or group of segments of plate, and each surface has sequence of knives, grooves and webs. Knives are arranged in rows, rows are separated by annular webs with substantially fixed radial location, and grooves are located adjacent to blades in rows so that grooves form path in form of serpentine extending radially between opposite plates or set of segments of plate on opposite discs or cones.

EFFECT: opposite plate or plate segments group are located so that annular connection strap on one plate or group of segments of plate face approximately towards middle row of blades on opposite plate or group of segments of plate.

SUBSTANCE: device, in body with dimensions of furniture element, comprises section of pulp making designed to produce pulp from used paper by soaking and battering of used paper, section of paper making designed to produce recycled paper on the basis of pulp from used paper made in pulp making section, and control section designed to actuate and control section of pulp making and section of paper making. Pulp making section comprises a unit of soaking designed to soak used paper by mixing and grinding and a battering unit designed to batter used paper soaked in soaking unit. Battering unit comprises at least one battering facility, and this battering facility comprises multiple battering elements arranged opposite each other with a small battering gap and moving relative to each other, besides, sides of these battering elements arranged opposite to each other interact to form a surface of battering action, and used paper passing through specified battering gap is pressed and battered with specified surface. Paints that form symbols and images on used paper are rubbed.

EFFECT: invention provides for environmental safety, reduced cost of operation and high level of confidentiality.

SUBSTANCE: in body of device of furniture size there is a section of cellulose production from used paper by means of used paper soaking and grinding, section of paper production for production of processed paper by means of treatment of cellulose from used paper produced in section of cellulose production, and control unit to drive and control interaction of cellulose production section and paper production section. Device is located in the room, where used paper is produced. By soaking and treatment of used paper in section of cellulose production, leakage or disclosure of confidential information or personal information written or printed on user paper, may efficiently be prevented, and further cellulose of used paper is processed by section of paper production, and processed paper is produced. Section of paper production includes a latticed conveyor, drying belt conveyor and drying roller.

EFFECT: high secrecy, safety for environment and low costs of production.

SUBSTANCE: invention concerns pulp and paper industry. Open moulding element, intended for double-grid papermaking machine, outfitted by pipeline and supporting moulding grids. Grids are supported by reference element set, which are supported by aspirate boxes tandem. Aspirate boxes has spun supporting surfaces and outfitted by separated areas of water drainage. Aspirate boxes are outfitted by, at least, four separated detached decompression sections. Spun surfaces radius of curvature reduce gradually along-running direction or reduce at consistent supporting surfaces along-running direction. Pitch of grids reference elements within every of decompression section remains steady and reduces in consistent decompression sections, or reduces along-running direction within every of decompression section. Aspirate boxes are located thereby grid reference elements are placed alternate relative to both sides of moulding grids.

EFFECT: improving of manufactured paper products quality.

SUBSTANCE: molding part of hybrid type is intended for paper making machine, which has two molding grates capable of combined displacement in direction of movement. Grates are supported by sets of support elements, which are supported by suction boxes. Suction boxes have curved supporting surface and are equipped with at least four separate detached zones of depression installed inside molding part. Radiuses of curvature of curved surfaces decrease progressively in direction of movement or reducing at serially arranged support surfaces in direction of movement. Pitch of support elements of grates inside every depression zone is constant and decreases in direction of movement in serially arranged zones of depression or decreases in direction of movement inside every zone of depression. Suction boxes, which support grates supporting elements, are arranged so that supporting elements of grates are arranged in staggered order with respect to sides of both molding grates.

EFFECT: increased quality of paper products.
