摘要： The present invention relates to a vibratory screening apparatus which comprises a vibratable screen element (2) mounted in a basket (4), which basket (4) is mounted over a reservoir (6) which contains and holds a pool of liquid slurry (8). A first end (10) of the screen element (2) is disposed within the reservoir (6) such that it is submerged in the body of liquid slurry (8). The reservoir has a deep end (12) in which the first end (10) of the screening element (12) is disposed and a second shallow end (14) above which a median portion (16) of the screening apparatus is disposed. The second end (18) of the screen element (2) is disposed above a portion (20) of the reservoir which extends above the surface of the body of liquid slurry held within the reservoir (6). Vibration means are provided for vibrating the screen element such that oversized solids in the liquid slurry in use of the operation are dewatered on the screen element and are discharged from the second elevated end of the screen element and underside solids pass through the screen element, where they may be collected. A vibratory screening machine is also described.

摘要： The invention relates to a device for filtering liquids, comprising two shafts (11) which are parallel to each other or at an acute angle to each other. Each shaft (1) carries a stack of discs (2) which extend perpendicularly to the shaft axis and which are connected to the shaft (2) in a rotationally fixed manner. The discs (2) of one disc stack are engaged in the intermediate spaces between the discs of an adjacent discs stack. At least one of the shafts (1) is drivable and at least one of the shafts is hollow and is provided with bores (1-2). Some of the discs have channels (2-4) inside them which are conductively connected to the inside of their hollow shaft (1). A ring-shaped distancing element (3) is located between each pair of adjacent discs (2) of a shaft. According to the invention, a device of this type is characterized as follows: the distancing element (3) is sealed in relation to the adjacent discs (2); said distancing element (3) is connected to the shaft (1) in a rotationally fixed manner; and the support ring (3-1) is oversized in relation to the shaft (1) so that a channel (4) is formed between the inner surface of the support ring (3-1) and the outer surface of the shaft (1), this channel extending at least over part of the length of the shaft (1).

摘要： The invention relates to a grading or filtration device for multi-phase mixtures, in particular liquids containing fibrous materials, comprising a housing with at least one supply line, at least one drain line for the treated liquid, at least one drain line for the retentate and the impurities and at least one filtration or grading surface, which is traversed by the liquid and whose rear face is connected to the drain line for the treated liquid. The invention is provided with devices for generating a defined flow characteristic on the filtration or grading surface, onto which the liquid flows. Said device is characterised in that the filtration or grading surface consists of at least one substantially rigid cover surface (10) of at least one essentially circular filtration plate (3) comprising a hollow internal chamber, which can be rotated about a substantially central axis (2, 2'), said internal chamber being connected to the drain line for the treated liquid. At least one additional element lies directly adjacent to the filtration or grading surface and the device also has guide and drive devices, which allow said element and the filtration plate (3) to execute a displacement in relation to one another, parallel to the plane of the filtration plate (3).
