摘要： The present invention relates to a process for production of upgraded TMP to SC/LWC qualities. The newsprint pulp is pumped to an LC-refiner (1) in which the average fibre length is reduced, and is then transferred to a primary screen (2) in which the pulp is divided into a primary accept and a primary reject with the aid of a slotted screen basket which has a narrow slot width. The primary accept is transferred to the main line, where the primary reject is dewatered and then refined in an HC-refiner (3). The refined primary reject is then transferred to a secondary screen (4) in which the reject is divided into a secondary accept and a secondary reject with the aid of a slotted screen basket which has a narrow slot width. The secondary accept is returned to the main line and mixed with the primary accept from the primary screen.

摘要： In a method and an arrangement for continuously producing lignocellulose-containing boards, the material is disintegrated into particle and/or fibre form, glue-coated, dried, and formed into a mat (1). The mat is pressed into board form (3) in a continuous steam injection press (2) and the board then passed through an after-conditioning zone (4). A specific volume of air having a specific moisture content and temperature is drawn through the board (3) in the after-conditioning zone (4) by suction.

摘要： A process for separating a fibre suspension wherein undesired impurities, such as printing ink and other contaminating substances, are separated from the fibres in a flotation tank and the fibre suspension in admixture with gas is introduced into the tank via directed jets having a high inlet velocity. The tank has inlet openings for the mixture of suspension advantageously located at or close to the bottom of the tank and the jets of suspension are directed upwards, towards the free surface of the suspension in the flotation tank.

摘要： The present invention relates to a method of manufacturing boards from lignocellulose-containing material, wherein the material is disintegrated into particles and/or fibres, is dried, glue-coated, and then formed into a mat (4). The mat formed in a first step (1) is compressed into a board that has a generally uniform density, and is pressed in a second step (3; 33) into a finished board. According to the method, the board is subjected between the first step and the second step to an intermediate step (2; 32) in the form of at least one operation of machining by cutting, such as to obtain a pattern on or in the board, while retaining the generally uniform density of the board. The invention also relates to an arrangement for carrying out the method.

摘要： Apparatus is disclosed for dewatering aqueous suspensions including a pair of rotatable rolls forming a nip therebetween, so that the aqueous suspension can pass downwardly through the nip and be dewatered by removing a filtrate from the suspension, and the dewatered suspension can pass downwardly from the nip, at least one of the rolls being liquid permeable, and at least one screen adjacent to the roll and disposed below the nip, the screen is separated from the roll by a predetermined distance and extends along its length, the predetermined distance being a sufficient distance so that a film of filtrate on the roll passes between the roll and upper end of the screen on one side of the screen and the dewatered suspension passes on the other side of the screen so that the filtrate is prevented from contacting the dewatered suspension below the nip.

摘要： A doctor arrangement for roll presses includes for each press roll (1, 2) a web transfer device (6, 7) which lies in abutment with the barrel surface of its respective roll or in abutment with a wire mounted on said barrel surface. The web transfer device (6, 7) comprises doctor sections (13) having doctor blades (8, 9) and included in a module system. The sections (13) are supported by a coarse shredded trough (5) arranged above the press roll nip (3) and forming, together with the doctor sections (13), a rigid construction in the longitudinal direction of the rolls (1, 2).

摘要： A centrifugal pump for pumping a pulp suspension where the pump comprises a housing (10) with an inlet and an outlet for the pulp suspension, and an impeller on a rotary shaft (13) with pump blades (15) extending from a hub (16) outward along a wheel disk (17). Openings (19) for the discharge of gas are formed in the wheel disk (17). The hub (16) behind the wheel disk (17) is provided with vacuum pump blades (20), which are surrounded by a vaccum pump housing comprising an outer cylindric wall (22), which is eccentric in relation to the vacuum pump blades (20), and a rear wall (23) with suction port (24) and, respectively, exhaust port (25) for gas. The vacuum pump housing is axially movable for adjusting a gap (31) between the hub (16) and outer wall (22). A gas passage (29) is located outside the outer wall (22) for communication between the openings (19) in the wheel disk (17) and gas suction port (24). The gas exhaust port (25) is connected to a chamber (26) for gas evacuation.

摘要： A screen device for separating fibre suspensions comprises a screen (40) defining a central chamber (36), and a rotor (15) in the central chamber having a first (21) and a second (27) rotor portion, respectively, provided with first (43) and second (41) pulsation elements, respectively, for pulsating the suspension close to the screen along a first (11) an a second (9) axial screen portion, respectively, of the screen. The first rotor portion (21) and the first axial screen portion (11) define a first screen chamber (39) and the second rotor portion (27) and the second axial screen portion (9) define a second screen chamber (37). Distribution means (22, 28) are provided for dividing the incoming fibre suspension into two part streams having the same axial directions in relation to the rotor and for distributing the two part streams to the first and second screen chambers (39, 37), respectively.
