摘要： In a slurry filtering apparatus having valves and valve seats of abrasion-resistant metal, a pump pressurizes and ejects a slurry containing hard particles at a high concentration. The flow of slurry is forced upon a filter surface in a direction oblique to it. Since the ejection of slurry causes cavitation and abrupt changes in velocity in the flow, shearing forces are created to scatter larger particles. This prevents filter-cake deposition while permitting parallel-flow filtration.

摘要： An auxiliary filter for removing residual particles from already filtered cutting fluids used in metal cutting machines, the auxiliary filter including a hollow wheel member (20) rotated in a sealed tank (16) into which the filtered liquid flows. Pressurized liquid passes through a fine screen (38) on the perimeter of the rotating wheel to capture any residual particles. A high pressure backwash jets are directed at the screen as it rotates past an array of nozzles (78), and a collection trough (76) draws any dislodged material away and out of the tank.

摘要： The present invention relates to a method for treating a pulp suspension in which the suspension is rotated in a rotationally symmetrical, rapidly rotating and permeable screen basket so that the suspension is subjected to the influence of a centrifugal force and dewatered at the same time as the suspension is conveyed by a rotating screw along the inner wall of the screen basket. The invention is characterized in that the suspension is caused to rotate by means which are arranged at the entrance to the screen basket, and in that the outer edges of the said screw bear against or are immediately adjacent to the screen basket and rotate at a higher speed than does the screen basket so that the screw scrapes the inner wall of the screen basket. The invention also relates to a device for implementing the method, which device comprises a housing (12), a screen basket (20) which is rotatably arranged in the said housing (12) and which is provided with screen openings, a screw body (72) which is rotatably arranged in the said screen basket (20) and which is arranged with a screw blade (79), an inlet (59) to the said screen basket (20) for the pulp suspension which is to be treated, an outlet (46, 52) from the said screen basket (20) for the pulp suspension which has been treated, and on outlet (62, 64) from the said housing (12) for liquid which has been removed. The device is characterized in that the said screen basket (20) is able to be rotated, via a transmission (26) which is arranged with a gearing, by a drive element (30), in that the screw body is able to be rotated, via a transmission (84) which is arranged with a gearing, by the said drive element (30), in that the screw blade (79) of the said screw body (72) moves along the inner side of the screen basket (20), with the gearing of the transmissions (26,84) being chosen so that the screw body (72) rotates faster than does the screen basket (20), so that the screw blade (79) has a scraping effect on the inner side of the screen basket (20), and in that an element (102) for initiating rotation of the pulp suspension is arranged at the inlet (59) to the screen basket (20), which element (102) is able to cause the pulp suspension to rotate when it enters the said screen basket (20).

摘要： In vibratory screen filter apparatus, a plurality of vibratory screening units (110, 112, 114) are provided. Each unit has its own filter screen (e.g. 12) and vibrating means (e.g. 17, 19) for vibrating the screen, and receives mixture to the process from a common inlet reservoir (100) which includes means (116, 118, 120) for varying the relative rates of supply of mixture to the screens of the screening units. Sensor means (130, 132, 134) detects the amount of mixture on each screen, and the output of the sensor means is used by control means (136) which controls the amount of mixture deposited on each unit, and can selectively activate or de-activate units to cope with changes in the required rate at which the apparatus is to process a mixture of drilling mud and cuttings.

摘要： A screw type hydroextractor having a diametrically larger first cylindrical casing (1) and a diametrically smaller cylindrical casing (11) which is disposed in the first cylindrical casing (1), with a ribbon shaped screw vane (14) rotatably disposed in an annular space (13) defined between the two cylindrical casings. Dewatering screens (21,22) are provided in the first and second cylindrical casings at predetermined locations, and an outlet port (6a) for dewatered material is provided at one end of the annular space, the outlet port (6a) being biased by a valve member (41) in a closing direction under a predetermined biasing force. Water that has entered the second cylindrical casing is discharged outward through a water outlet. The ribbon shaped screw vane (14) is rotatable separately from the cylindrical casings (1,11) and, therefore, material being processed can be prevented from turning with the cylindrical casings (1,11). Both the inner (11) and outer cylindrical casings (1) are provided with a screen (22,21). This permits an efficient dewatering operation.
