摘要： A device for filtering liquids has an annular disc (1) with at least one perforated side wall. A plurality of separate sections (14) of a filter medium are applied onto frames (13) and each said section covers a part of the perforated side wall. According to the invention, the separate sections (14) of filter medium are attached to the respective frames (13), such that each section and its frame form a filter unit (12) separate from the perforated side wall, each filter unit being releasably connected to the disc. The filter units can be made light-weight and suitably identical, which facilitates exchange of filter units with defective sections of filter medium for new filter units.

摘要： Installation à hydrocyclones comprenant plusieurs hydrocyclones (1) disposés en groupes constitués d'au moins deux hydrocyclones, chaque groupe étant composé d'un seul élément unique. Les hydrocyclones s'étendent pratiquement radialement dans un espace d'admission annulaire (11) destiné à un mélange liquide devant être séparé. L'espace d'admission s'étend de manière concentrique autour d'un espace cylindrique de fraction lourde (10) recevant une fraction lourde produite, du mélange liquide provenant des hydrocyclones. Selon cette invention, les groupes d'hydrocyclones sont répartis autour de l'espace cylindrique de fraction lourde dans la direction de la circonférence de ce dernier et sont espacés les uns des autres dans l'espace d'admission de manière à permettre l'écoulement du mélange liquide entre les groupes d'hydrocyclones adjacents.

摘要： A feed and dewatering device for dewatering and squeezing material in form of sludge, sediment, suspensions, peat, etc., comprises two co-operating sections (1; 2), each comprising a feed screw (19, 20; 21, 22) and a seave mantle (4; 15) surrounding the feed screw. The first section (1) in the feed direction is formed for dewatering mainly by self-drainage. The section has a rotating seave mantle (4) and is provided with means (33) for cleaning the seave mantle holes (5). The second section (2) is formed for increased compression of the material, wherein the thread height for the feed screw (21, 22) is less at the outlet (24) of the section (2) than at the inlet to this section.

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.

摘要： A hydrocyclone plant comprises a great number of hydrocyclones (1) arranged in a plurality of separate assemblies (10, 10A, 10B). Each hydrocyclone assembly includes branch pipes (6, 6A), to which the hydrocyclones of the assembly are connected in parallel relationship to one another. There are main pipes (13) of the same number as that of the branch pipes of each assembly, the branch pipes of each assembly being connected to said main pipes, respectively. According to the invention, clamping means (8, 9) are provided for releasably clamping each hydrocyclone substantially transversely against at least one of the associated branch pipes (6, 6A) of the latter, and the individual assemblies include various numbers of hydrocyclones, for optimizing the desired capacity of the hydrocyclone plant.

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.

Date Dec. 27, 1990.A filter for continuous filtration of a liquid includes conventionally a vessel having a center shaft on which is arranged at least one rotating filter element defining an inner space for liquid obtained at filtration. Further there is provided a washing device for washing of material deposited on the filter element, a connection between said inner space and outlet means from said vessel and a separator connected to said outlet and adapted for separating filtrate and gas. Means is provided outside said vessel for generating an overpressure in the gas space of the vessel and a lower pressure in the interior of the filter element at least corresponding to the evaporating temperature of the filtrated liquid for evaporation of the liquid in the separator. The separator is provided with a cooling device for cooling the separated gas and an outlet for condensate obtained at cooling.

摘要： In a hydrocyclone the separation chamber (2) has a circumferential wall (3) provided with at least one turbulence creating member (12), which extends along the circumferential wall and crosses a helical path (10), along which a liquid stream is generated during operation. According to the invention, the turbulence creating member is formed by a set-off (12) on the circumferential wall (3). The set-off is formed and dimensioned such that said liquid stream substantially looses its contact with the circumferential wall, as the liquid stream passes the set-off. As a result turbulence is created in a layer of the liquid stream situated closest to the circumferential wall, without the liquid stream becoming any substantial flow component directed inwards in the separation chamber.
