Abstract: The invention concerns a drum washer. The washer has a shaft formed by two cones (46) placed with their bases against one another. The shaft can be used as a supporting structure for the drum. Vanes (48) can also be placed on it for assisting in collecting washing liquid falling from the upper part of the drum separately from the washing liquid ending up on the bottom of the drum. The washer is especially suitable for washing cellulose pulp.

Abstract: Rotary filter including a perforated, rotatable drum and at least one blowback valve located in close proximity to the interior surface of the drum. In a preferred embodiment, the blowback valve includes an opening adjacent the drum for the discharge of a gas and the opening includes at least one radial position adjusting device alignable with a hole in the perforated drum, whereby the radial position of the blowback valve in relation to the interior of the drum is adjustable externally through perforations in the drum. The external adjustment permits drums longer than possible with prior art rotary filters.

Abstract: A device for preventing re-wetting of thickened suspension in a filter of the type where a plurality of rotatable, axially spaced annular filter disks (3) are partially submerged in a container (1) for suspension, and where a collection trough (4) extends centrally through the filter disks (3) for collecting thickened suspension falling therefrom. Each filter disk comprises a plurality of filter sections (5) and each filter section is connected to a filtrate duct (7) situated at the circumference of the disk. At each filter disk (3) is arranged an arcuated channel (14) extending outside of the edges of the collection trough (4) such that filtrate flowing from a filter disk (3) is guided past the collection trough (4) and down into the suspension container (1).

Abstract: The device comprises a slowly rotating screening drum (1) which is provided with feeding devices for feeding waste water into the screening drum from one end (2) thereof and with devices for discharging solid substances out from the other end of the screening drum. The water is thereby filtered through a mantle (5) of the screening drum. The solid substances for their part are passed forwards inside the screening drum by means of transversal ribs (4) positioned slantingly with respect to the direction of rotation of the drum and, further, are agitated in the screening drum by the action of longitudinal ribs (3) extending over the length of the drum. In order to provide a filtration as effective as possible, at least some of the longitudinal ribs (3) are slanted with respect to the radial direction of the screening drum (1) in such a manner that an angle between that surface of the longitudinal rib (3) which faces in the direction of rotation of the screening drum and the inner surface of the screening drum mantle (5) is smaller than an angle between that surface of the longitudinal rib (3) which faces backwards with respect to the direction of rotation and the inner surface of the screening drum mantle (5).

Abstract: A rotary disc vacuum filter includes a trunnion (2), a plurality of conduits (3) detachably mounted to the trunnion (2) which conduits (3) have an open end (5), an opposite closed end (6), openings (4) therealong and a groove (8) adjacent the open end (5) of the conduits (3) shaped so as to hold an O-ring (9), a collar (11) mounted to rotate with trunnion (2) having apertures (12) for slideably accepting the open end (5) of the conduits (3) so that the O-ring (9) forms a seal and means (15) for detachably mounting the conduits (3) to the trunnion (2) adjacent the closed end (6) of the conduits (3). The filter further including ferrules (37) which are detachably mounted in the openings (4) of the conduits and (3). The plurality of conduits and ferrules mounted in accordance with the above facilitate problems related to replacement and alignment of filter elements.

Abstract: An automatic filter cleaning system which includes a solvent dewaxing filter which removes wax from a wax mix slurry and provides a filtrate. Status control apparatus is connected to the filter for affecting the operational status of the filter. Drain apparatus responsive to a control signal controls draining of the filter. Cleaning apparatus is also connected to the filter. A control network connected to the status apparatus, the draining apparatus and the cleaning apparatus controls those apparatus in a manner so as to automatically change the state of the filter from an operational state to a down state to drain the filter and to clean the filter while the filter is in the down state.

Abstract: A filtering apparatus filters cutting oil containing metal chips so that the filtered cutting oil can be recycled. The filtering apparatus includes a reservoir, a filtering drum journalled within the reservoir and having a filtering screen extending about the periphery of the drum, chip discharge device for carrying separated metal chips of the reservoir, a discharged chip receiving bin disposed outside of the reservoir adjacent to the discharge end of the chip discharge device and a filtered oil receiving bin disposed outside of the reservoir adjacent to a filtered oil discharge area of the reservoir. A permanent magnet is disposed outside the reservoir so as to attract metal chips to the bottom of the reservoir from where the chips are discharged by the chip discharge device.
