Abstract: A method and apparatus for dewatering a slurry of fine particles including a dewatering table and a forming fabric passed across the table. Vacuum is applied to the table and the forming fabric. A first slurry of particles is introduced through a primary headbox to the forming fabric. A second slurry of finer particles is introduced through a secondary headbox to the forming fabric. The primary and secondary headboxes are positioned relative to each other and the table so that the first slurry is introduced to the forming fabric before the second slurry as the fabric moves across the table. Vacuum is applied to the first slurry to form a mat of first slurry particles upon which the second slurry of finer particles is deposited to be dewatered thereby minimizing the loss of fine particles through the forming fabric and maximizing the amount of retained dewatered particles.

Abstract: Belt 21 on which a residual filter cake has been formed by the action of a suction box (16, FIG. 1) on a slurry, is brought over a filter grid 46 superimposed on a membrane 42 inflation of which causes the filter cake to be compressed upwards against stationary pressure plate 53 for further dewatering. The grid 46 has parallel grooves in its top surface and further parallel grooves in its under-surface, and intersecting with and communicating with those in the top surface, to permit suction to be applied by way of suction pipe 146 and drain duct 45. The belt 21 is intermittently driven, but the arrangement may be such that the belt moves continuously and the grid 46, membrane 42 and pressure plate 53 move in sequence, forwards from a starting position for a certain distance in contact with the belt while applying pressure to the filter cake and then backwards to the starting position out of contact with the belt.

Abstract: A machine for filtering slurry includes a frame with two drums mounted to said frame for rotation and spaced apart from one another. An endless, perforated drainage belt is disposed around the two drums to define a substantially horizontal drainage surface on the top of the drainage belt. A vacuum pan is located below the drainage surface to apply vacuum to material on the drainage surface, and a raising and lowering system is coupled to the vacuum pan to selectively support the vacuum pan in sealing engagement with the drainage belt and to selectively lower the vacuum pan away from the drainage belt.

Abstract: A portable machine for separating liquid from a slurry comprising an interconnected pair of beams cantilevered above the base with a plurality of rollers rotatably mounted between them. An endless belt is carried on and driven by the rollers to move upward from a slurry hopper, over a source of liquid-drawing vacuum, and back down under the hopper and collector tank. The belt and rollers are scraped and washed on the return run and, because of the cantilevered configuration, the belt is easily removed by sliding it off the rolls from one side of the machine.

Abstract: In a rotary drum vacuum filter, the drum sectors are connected by conduits to apertures in a rotary valve member on the drum which is opposed to a fixed valve member. The valve members thus control supply of vacuum (to cause suction filtering) and pressurized gas (to blow the cake of filtered material from the filter) to the drum sectors as the drum rotates. In order to eliminate the time delay between suction and blowing which is needed in order to allow the conduits to purge, another group of conduits is provided, having one-way valves adjacent their connection to the drum surface; this group is used only for blowing. The different groups of conduits are connected to apertures of the rotary valve member at different radial distances from the axis of rotation.

Abstract: In a water screening installation, a traveling water screen removes both refuse and aquatic life from a stream. The aquatic life, such as fish and shrimp, are uplifted in pans that are mounted on an ascending run of the screen. At a location above the stream, the pans are gently flushed by a low pressure spray of water. The fish are then returned to the stream, as soon as practical, to keep the mortality rate at a minimum. Each of the pans has an inner side that is parallel to a screen tray within the traveling water screen. This inner side is also tangential to a curved bottom portion of the pan. Extending tangentially from the opposite side of the curved bottom portion of the pan is an outer side that has a continuing profile at or below an extended tangential line from the point where the outer side is tangential to the curved bottom portion. A spray of water that is directed against the inner side of the pan is deflected to flow smoothly about the curved bottom portion and the outer side of the pan to a discharge lip that curves from the outer side in a direction reverse to the curved bottom portion. Water standing in the pan together with any fish therein are drawn along with the deflected spray water undercurrent.
