摘要： A flat bed, Fourdrinier-type, countercurrent washer for cellulosic pulp incorporates a pressing section at the downstream end thereof which includes the couch roll and additional rolls that carry out multiple mechanical pressing operations on the pulp after it has been subjected to multiple stages of displacement washing without mechanical treatment. As a result, where such washers without mechanical pressing deliver pulp of a consistency of the order of 15% solids, this washer increases the pulp consistency to as high as 40% while correspondingly increasing the effectiveness of the washing operation as a whole.

摘要： A disk refiner is provided with refiner plates having a working surface on each side thereof, and these plates are first mounted with one working surface in face to face engagement with the supporting face of the stator or rotor of the refiner. After the exposed working surfaces of the plates have been substantially worn away by use of the refiner, the plates are temporarily removed, their worn surfaces are ground into substantial parallellism with their unused working surfaces, and they are then replaced in the refiner with their ground surfaces engaging the faces of the stator and rotor.

摘要： Screening apparatus for paper fiber stock and other fiber suspension is especially designed to handle relatively suspension containing stringy material. A perforate screen cylinder forms the outer wall of the supply chamber for the stock to be screened, and a rotor operates in the supply chamber and includes vanes which travel in spaced relation with the inner wall of the screen cylinder. These vanes are supported on the rotor hub by imperforate arms of substantial axial extent which act as propeller blades to maintain a high rate of circulation of the stock within the supply chamber and also to direct the stock toward the reject collecting chamber from which stock is continuously discharged at a high volumetric rate approaching or equal to the rate of discharge of accepted stock. Helical ribs on the inner surface of the screen cylinder aid in channeling the flow of reject-containing stock toward the reject outlet.

摘要： A process of preparing a suspension of paper making fibers in water for use in the making of paper includes the steps of treating a mass of fibrous materials, such as shredded waste paper materials, with steam under pressure in a closed vessel, and transferring the resulting mixture of treated materials and steam to a second vessel containing a substantial volume of aqueous liquid in such manner that the mixture impacts directly the liquid in the second vessel at very high velocity causing disintegration of the solid materials into essentially separate fibers and contaminant particles accompanied by dispersion of these solids in the liquid in the second vessel. Systems are described for carrying out these process steps on either a continuous or a batch basis.

摘要： A cutter for comminuting a moving continuous sheet or web, such as paper broke, in the dryer or converter section of a papermaking machine, includes a plurality of high pressure water jet cutting nozzles positioned in a conduit section for receiving such broke from the papermaking machine. In one embodiment the nozzles are arranged in banks positioned to impact the sheet as it passes through the conduit section, from opposite sides, and are mounted on water conduits which, in turn, are mounted for reciprocating movement and are oscillated transversely of the direction of sheet movement by a mechanical drive. The cutting jets from the high pressure nozzles impact the sheet simultaneously at opposite sides, while being reciprocated to reduce the sheet into a multiplicity of smaller discrete or easily separable pieces which fall through the bottom of the conduit section, for further processing or disposal. The nozzles may be directed at an angle to the direction of sheet movement, so as to impart a force component tending to pull the sheet through the conduit section. In another embodiment, an open face roll forms a backing support for the sheet and a mutually reciprocating pair of nozzle banks have cutting jet sprays directed against and through the sheet supported on the open face roll.

摘要： A method for thickening a liquid suspension of solid particles, such as papermaking pulp in water, uses a pair of spaced apart rolls and a woven wire or plastic wire belt trained around these rolls. The suspension is supplied at the first roll for centrifugal extraction and is carried by the belt to the second roll for further water extraction and thickening, and is then discharged from the apparatus. In one embodiment, the first roll is formed with an open surface, and the suspension is delivered to the web at least partially by flowing both into and out a roll chamber via the first roll openings, from a headbox in the on-running wedge zone. The apparatus may also include a second roll which is porous and has auxiliary water-removing appliances associated therewith, including blow boxes for forcing air either radially inwardly or radially outwardly of the second roll, and an auxiliary nip roll for creating a zone of higher compression for mechanical extraction of water from the mat of solid particles between the belt and second roll. Rewetting of the mat caused by water entrained in the wire mesh cavities is reduced by the impingement of air jets to remove such water.

摘要： A method and apparatus for treating a suspension of liquid, paper making fibers and undesirable rejects to remove a substantial portion of the rejects from the suspension. A cylindrical screen is utilized which has narrow slots on the order of 0.001 to 0.008 inch in width disposed normally with respect to the screen axis, and bars projecting from the inlet face of the screen and cooperating with rotating foils for creating a field of high intensity, fine scale turbulence adjacent the inlet face of the screen. This permits the paper making fibers to pass through the narrow screen openings but causes very small reject particles, which would pass through the larger openings of conventional paper making screens, to be removed without fractionation of the paper making stock or appreciable variation in the consistencies of the feed, accepts and rejects.

摘要： Pressure screening apparatus for screening a suspension of paper fiber stock employs a rotor in which a single impulse or foil member is carried or positioned to move along a discrete portion of the screen surface. This arrangement improves efficiency of operation of the pressure screen by reducing the rotational effect of the rotor on the stock suspension being screened and by providing a less disturbed screening region through which the single foil operates. Embodiments are shown in which multiple single impulse elements sweep over discrete portions of a screen and in which a single foil is combined, in screening apparatus, with multiple foils in accordance with the increase in consistency of the stock as it passes through the screen.

摘要： Apparatus for screening papermaking stock comprises two annular flat screening plates arranged in parallel spaced relation to form a screening chamber therebetween which is bounded on its outer periphery by a cylindrical wall, and wherein a rotor includes vane portions which extend into this screening chamber to agitate the stock so that particles of sufficiently small size can pass through the screening plates into annular compartments outside the screening plates from which they flow into a peripheral chamber having an outlet port. The screening chamber includes an annular space which is surrounded by the accepts chamber and is radially beyond the vane portions of the rotor wherein reject material collects for discharge through an outlet tube which extends through the accepts chamber to the outside of the apparatus. The apparatus as a whole comprises a main assembly which includes one of the screening plates and the rotor, and a subassembly which includes the other screening plate and can be removed from the main portion to expose the screening plates for replacement or other servicing.
