摘要： In a hydrocyclone plant for treating fibre suspensions comprising a multiplicity of hydrocyclone bodies (1) each hydrocyclone body is mounted in a hole in a wall (5) and is sealed to the wall with the aid of a sealing ring (18). According to the invention the sealing ring is made of an inexpensive chemical resistant material and is radially cut through to form two free ends on the sealing ring. The hydrocyclone body is provided with a sealing surface (12) having a radial extension which increases along the hydrocyclone body. Axially along the sealing surface (12) a projection (22) extends between the free ends of the sealing ring. When mounting the hydrocyclone body the sealing ring (18) is adapted to be entrained by the wall (5) along the sealing surface (12), so that the sealing ring is expanded and seals between the sealing surface and the wall.

摘要： A suspension containing fine and coarse particles is sprayed under high pressure by means of spray nozzles (10) against a rotating filter medium (7), so that the suspension is separated into a fine fraction, which passes through the filter medium and which contains said fine particles, and a coarse fraction, which does not pass through the filter medium and which contains said coarse particles. According to the invention the filter medium (7) is rotated by means of a drive motor (6) at a speed such that coarse particles and liquid developing on said side of the filter medium are removed from the filter medium substantially as a result of the centrifugal force said coarse particles and liquid are subjected to by the rotating filter medium. In consequence the filter medium is efficiently kept clean during operation, which increases the capacity and improves the separation efficiency.

摘要： PCT No. PCT/SE91/00356 Sec. 371 Date Nov. 18, 1992 Sec. 102(e) Date Nov. 18, 1992 PCT Filed May 17, 1991 PCT Pub. No. WO91/17806 PCT Pub. Date Nov. 28, 1991.In a rotating filter a filter cloth (18) is arranged outside a filter skeleton (34, 36). The filter cloth is provided with at least one bending resistant element (37, 38) extending through a pocket (49) arranged in or on the filter cloth (18) to restrain bulging of the filter cloth due to forces perpendicular to the plane of the filter cloth. The filter sector skeleton (34, 35, 36, 45) is provided with radially outer support and guide means (43, 44) and radially inner support and guide means (45, 46). The bending resistant element (37, 38) is at its ends adapted for detachable engagement with said means such that the ends are undisplaceable perpendicularly to the support and guide means (43, 44, 45, 46). Preferably, at least one end of the bending resistant element is displaceable in the circumferential direction of the filter sector.

摘要： An apparatus for dewatering and squeezing treatment of material in form of sludge, suspensions, peat, etc, includes as ending treatment part a screw press section (12-14; 28-30) including a press screw (12, 13; 29, 30) and a sieve mantle (14; 28) surrounding the press screw. An out-feed section (7-10) positioned adjacent a dewatering device such as a drum filter, disc filter, bow sieve, etc, is positioned ahead of the screw press section. This out-feed section includes an out-feed screw (8-10) and a trough (7) surrounding this screw. The press screw (12, 13; 29, 30) and the sieve mantle (14; 28) of the screw press section is an extension of said out-feed screw (8-10) and said trough (7), respectively, and are arranged on the same central line. The dewatering device (5, 6) is provided with an inlet (1-3) for the material to be treated and an outlet means, for instance a scraper (21), for supplying the material from the dewatering device (5, 6) to the out-feed section (7-10).

摘要： A hydrocyclone assembly comprises at least one hydrocyclone (1) having at least two through flow members (2, 3) for distribution of liquid between the outside and the interior of the hydrocyclone, and circular cylindrical pipes (4, 5) of the same number as that of the through flow members of the hydrocyclone, the through flow members of the hydrocyclone being connected to the pipes, respectively. According to the invention each through flow member (2, 3) defines an annular end portion (6), which extends around a radial bore (7) in its associated pipe (4, 5) and abuts sealingly against the mantle surface of the pipe via a gasket (8) extending around said bore in the pipe.

摘要： Dans une installation à hydrocyclones pour traiter les suspensions de fibres comprenant une pluralité de corps d'hydrocyclones (1), chaque corps d'hydrocyclone est monté dans un trou situé dans une paroi (5) et est obturé par rapport à la paroi à l'aide d'un anneau d'étanchéité (18). Selon l'invention, l'anneau d'étanchéité est en matériau bon marché résistant aux produits chimiques et il est coupé radialement pour former deux extrémités libres sur l'anneau d'étanchéité. Le corps de l'hydrocyclone est pourvu d'une surface d'étanchéité (12) ayant une extension radiale qui augmente le long du corps de l'hydrocyclone. On trouve une saillie (22) disposée axialement le long de la surface d'étanchéité (12) entre les extrémités libres de l'anneau d'étanchéité. Lorsqu'on monte le corps de l'hydrocyclone, l'anneau d'étanchéité (18) est adapté pour être entraîné par la paroi (5) le long de la surface d'étanchéité (12), de sorte que l'anneau d'étanchéité est dilaté et assure l'étanchéité entre la surface d'étanchéité et la paroi.

摘要： La chambre de séparation (2), dans un hycrocyclone comprend une paroi circonférentielle (3) pourvue d'au moins un élément (12) produisant une turbulence, qui s'étend le long de cette paroi et traverse une voie hélicoïdale (10) le long de laquelle un courant liquide est généré au cours du fonctionnement de l'appareil. Selon l'invention, l'élément produisant la turbulence est formé par un épaulement (12) se trouvant sur la paroi circonférentielle (3). Le profil et les dimensions de l'épaulement sont tels que ledit courant liquide ne se trouve pratiquement plus en contact avec la paroi circonférentielle lorsqu'il passe sur l'épaulement. En conséquence, une turbulence est produite dans une couche du courant liquide la plus proche de la paroi sans que ce courant ne produise un déplacement sensible de l'écoulement vers l'intérieur de la chambre de séparation.

摘要： A fibre suspension is separated by a filter device having a hollow filter body (1) with a wall (2) of filter material, and a container (3). The entire fibre suspension to be separated is sprayed in the form of at least one liquid jet onto said wall (2) to force a fine fraction of the suspension containing most of said undesired particles through said wall of filter material into the hollow filter body, thereby leaving a created coarse fraction of the fibre suspension mainly containing fibres in the container outside the filter body. Relative displacement between the liquid jet and the filter material is provided. Said created coarse fraction is dewatered through the wall of filter material, and said dewatered coarse fraction is dicharged from the container.
