摘要： The object of the present invention is a method for making mechanical pulp, such as thermomechanical or chemi-thermomechanical stock. The mechanical pulp is used as a raw material for printing paper, and its freeness value is 30-70 ml CSF. The stock refined by the method is screened in several stages to form accept and reject stock portions. The wood raw material is refined at the first stage of refining at a superatmospheric pressure of over 400 kPa to form a stock that has a freeness value of 250-700 ml CSF.

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： The present invention relates to a method and apparatus for treatment of fiber suspensions in the pulp and paper industry. The invention relates in particular to intensifying the so-called post-screening or secondary screening of bleached pulp or pulp in the process of being bleached. It is characteristic of the method of the invention for treating fiber suspension in the so-called secondary screening, during which impurities are removed from the pulp by means of a pressure screen, i.e. a so-called primary screen, and the impurities are further treated at least in one screening stage, that the reject from the pressure screen mentioned is treated in one treatment step or several treatment steps at least one of which is a reverse hydrocyclone step. The apparatus according to the invention comprising at least a pressure screen (30) and intended for treating fiber suspension in the so-called secondary screening process in an apparatus is characterized in that the apparatus comprises at least one reverse hydrocyclone step (40; 46; 48; 57; 64).

摘要： An apparatus for filtering liquids, especially for recovering fibres from white water, includes rotatable filter discs (5) at least partly immersed in the liquid to be filtered, and a shaft wall connected to the discs and forming a circular cylindrical filtrate chamber, which extends centrally through the discs. A rigid stationary partition wall (19) extends in the filtrate chamber dividing the latter into at least two axial channels (20, 21). The partition wall (19) is spaced from the shaft wall and arranged, such that all of said axial channels receive various fractions of filtrate, respectively. Filtrate discharge means is provided for discharging said fractions of filtrate separately from the respective axial channels, such that the pressure prevailing in the filtrate of each channel is at least substantially as high as atmospheric pressure.

摘要： A disk screen or like shaft structure is disclosed in which screen disks (14), surround disks (24), and spacers (28) are connected together in modular relation. The surround disks (24) have metallic flanges (25) which shield the plastic spacers (28) which are located on either side of the surround disks (24) between the screen disks (14). The spacers (28) are formed of resilient plastic to allow the disks to deflect from their radial plane and the flanges (25) of the surround disks (24) are sufficiently smaller then the spacers (28) to avoid contact with the screen disks (14) in their deflected positions. The assembly is placed under a predetermined endwise compression and the module is mounted on a rectangular shaft (27) which is suitably supported for rotation. The assembly is particularly suited for screening of wood chips in the paper making industry where exposed plastic parts is undesirable.

摘要： In screening a fibre suspension, an accept and a reject are tapped off, tapping the reject being controlled by a valve (6). According to the invention, the pressure drop across the screening means is measured, and when this drop exceeds a predetermined first value the valve (6) is opened from a first to a second position and when the pressure drop falls below a second predetermined value or when a given predetermined time has passed the valve is returned to its position prior to opening. In this second position the reject valve (6) is preferably completely open. The accept flow may possibly also be constricted when the reject valve is in the second position.
