摘要： A deaeration vessel has a partition wall dividing the hollow vessel body into first and second portions, and defining a weir with a top surface establishing the level of pulp suspension in the vessel body. Turbulence in the deaerated pulp is minimized by providing the outlet for deaerated pulp immediately adjacent the partition wall, in the bottom of the vessel body first portion (on the same side of the weir as the inlet conduits for the suspension being deaerated). The weir is preferably configured so that the top surface, defining the liquid level within the vessel, overlies the outlet. A partition wall may extend substantially linearly at an angle of about 60.degree. to the bottom of the vessel, or it may have a vertical bottom with a top extending at an angle to the bottom, or it may be continuously curved from the vessel bottom to the top surface, about a horizontal and/or vertical axis. The outlet may have an enlarged, non-circular configuration at the bottom, which then tapers to a circular outlet conduit.

摘要： A device for cleaning obstructions from the reject end of a centrifugal separator without interrupting normal opertion. Modern small-sized separators, in particular, are liable to become blocked, and the usual method of removing the blockage is to use a water jet or pressurized air which is led to the obstructed reject end by various methods. The disadvantage associated with these methods is that the impurities removed by the jet partially contaminate the regular flow. This invention will help to avoid this because cleaning is effected by means of a device having a chamber into which the flow containing the rejected material is directed when the plug of the separator is opened. The chamber is fitted with a discharge orifice. In this way, the reversed flow removes the obstruction in the reject orifice, thus preventing it from contaminating the accept mass.

摘要： White water from a paper machine is treated in an improved fiber recovery process, i.e., the "save-all" process. Prior to the mixing of sweetener stock into the white water the sweetener stock is fractionated (undiluted) into fine and coarse fiber fractions, of which only the coarse fraction is fed as sweetener stock into the white water. The inlet line for the sweetener stock is provided with a fractionation apparatus for removing the fine fraction from the sweetener stock. Treatment apparatus may also be utilized to separate the white water into fine and coarse fractions before passing the fine fraction to a mixer for mixing with the sweetener stock coarse fraction.

摘要： A twin hydrocyclone used for instance in cellulose and paper mills for purifying pulp suspension, the twin hydrocyclone consisting of two hydrocyclones mounted with their larger ends against each other and having one common infeed connector and one common purified fraction discharge connector. The hydrocyclones of prior art have the drawback of complex design and of division of the feed flow causing disturbances in the feed flow in view of the hydrocyclone's operation. The twin hydrocyclone, meant to solve these problems, is characterized in that the feed flow from the common infeed connector of the hydrocyclones is directed to each hydrocyclone as a separate feed flow by means of a helical member the helices of which constitute, in each hydrocyclone, feeding ducts confined by the walls of the hydrocyclones.

The hydrocyclone comprising a separation chamber consisting in part of a cylinder part provided with at least one passage for the tangential input of the fibre suspension to be divided into different fractions and having within itself a coaxially disposed tube for removal of the lighter fraction, and in part of a sorter cone on the extension of said cylinder part and on the apex of which has been adjoined a conical nozzle which has been made more abruptly tapering than the cone part and which at its apex has a removal aperture for the heavier fraction. On the inner surface of the sorter cone and conical nozzle has been disposed at least one guide vane running in the axial direction of the cyclone and which imparts to the heavier fraction, travelling along a spiral path on the inner surface of the sorter cone and of the conical nozzle, a radially inwardly directed component of motion. The guide vane common to both the sorter cone and the conical nozzle is located at their point of juncture.

摘要： The present invention concerns a feed and accept duct system (4) for hydrocyclones (1), comprising common feed and accept ducts (7,8) which have by connecting tubes been connected to the parallel hydrocyclones. This type of construction is used, for instance, in purifying fiber suspensions, in which process the suspension is fed into the hydrocyclones (1) and the purified suspension is removed therefrom as a so-called accept fraction into the accept duct (8). It is essential in the invention that the connecting tubes of the feed and accept ducts (7,8) have been so placed on the different hydrocyclones (1) that the tubes are located substantially in parallel, that the feed and accept ducts have been formed inside a common shell (5) by dividing the space confined by it into two parallel ducts by means of a zigzag partition (6), and that the ends of the connecting tubes (11,12) are located at the folds formed by the bights of the partition, the partition confining the feed duct connecting tubes to be on the feed duct side and the accept duct connecting tubes to be on the accept duct side.

摘要： A method and apparatus for treatment of recycled fiber material and/or of the reject fraction discharged from paper mill screening systems of the short circulation of a paper machine, recover fillers as completely as possible and return the fillers back to the process as efficiently and economically as possible. The loss of fiber/mineral discharge as mill rejects from vortex cleaning and filler manufacture is decreased by treating a concentrated mineral fraction of the rejects to disperse the filler-mineral fraction and return the filler back to the paper making process.
