摘要： Apparatus and method for thickening a suspension of pulp in liquid employs three rolls (20, 22, 25) arranged in spaced relation with their axes defining a triangle, and a single loop of wire (30) is trained around and in wrapping relation with all three rolls. The first and third roll have a headbox (40, 45) which delivers a flow of the suspension to be thickened in such manner that it is trapped between the wire and the portion of the roll wrapped by the wire so that the trapped suspension is dewatered and concentrated by expression of liquid through the wire. The pulp deposited on the inside of the wire at each of the positions comprising a roll and headbox is collected from the surface of the second roll (22) and is transported out from within the triangular space within the wire loop. In one embodiment, the roll at each roll-headbox station has a grooved surface such that it forms separate strips of pulp on the wire, and the next roll downstream therefrom has a similar grooved surface offset axially from the preceding roll so that it causes strips of pulp to be deposited on the wire between the strips produced by the previous roll.

摘要： Apparatus for thickening a suspension of pulp material which includes an endless foraminous belt (30) wrapping two spaced horizontally supported rolls (20,22). A doctor mechanism is provided for transferring thickened pulp from the surface of the second roll (22) into a trough (50) mounted in the space bounded by the two rolls (20,22) and the upper and lower runs of the belt (30). The doctor mechanism includes a rigid doctor blade (55) mounted with its working edge in close but spaced relation with the bare surface of the roll (22) to remove pulp therefrom without contact with the roll surface. The mounting apparatus periodically oscillates the blade (55) about a horizontal axis to move its working edge away from and back to its closely spaced working relation with the roll (22).

摘要： A system for separating paper fibers from contaminants of similar lower specific gravities employs a reverse centrifugal cleaner (110) wherein the discharge port for lights (reject) is located at the apex of the internally conical cleaner body (125). The discharge port is formed by a tube (123) which has its inner end located in the open apex end of the cleaner body (125) and is of smaller diameter than said apex end to define therewith an annular discharge outlet for heavies (accepts). The tube is releasably secured in position by bayonet locking means (136) so that it can be temporarily retracted to relieve blockage of the heavies outlet.

摘要： s7 Apparatus for screening papermaking stock comprises two annular flat screening plates (36, 46) arranged in parallel spaced relation to form a screening chamber (55) therebetween which is bounded on its outer periphery by a cylindrical wall (35). A rotor (15) includes vane portions (60) 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 (75) outside the screening plates from which they flow into a peripheral chamber (77) having an outlet port (78). The screening chamber (55) includes an annular space (70) 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 (71) which extends through the accepts chamber (77) 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 (15), and a subassembly which includes the other screening plate (46) and can be removed from the main portion to expose the screening plates for replacement or other servicing.
