摘要： A hydrocyclone plant comprises a great number of hydrocyclones (1) arranged in groups, and a main chamber (10) for receiving a fraction of a separated liquid mixture from all of the hydrocyclones. Each hydrocyclone group has a sub-chamber (20) for receiving said fraction from the group, and each sub-chamber is connected to the main chamber. According to the invention, said fraction is directed into each sub-chamber, such that a vortex of the fraction is generated in the sub-chamber, for creating an increased counter pressure in the latter.

摘要： A filter for continuous filtering of a suspension under pressure and/or vacuum comprises a vessel (1) having a center axle (2) on which filter discs (3) are arranged at a distance from each other along the central axle. The filter discs consist of filter sectors having surrounding filter cloth and internal channels and between the filter sectors and an outlet from the vessel (1) there is a connection in the central axle (2). Moreover, a removal means (7) is arranged for removing the filter cake (8) on the filter cloth obtained during the filtering operation and means (12) for receiving the filter cake material scraped-off by said removal means (7). Said removal means (7) consists of a substantially vertically arranged scraper for removing at least an outer layer of the filter cake along a substantially vertical line. Furthermore, the central axle (2) is preferably formed with only one channel common for the filtrate and the gas from all filter sectors in vessel (1) and consists preferably of a tube.

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： 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.
