Definitions

  • the present invention relates to a filtering device. More particularly, the filtering device of the present invention is intended to facilitate filtering or concentrating of solids in fluids.
  • a filtering device may also be known as a concentrating device.
  • filtering devices function by passing a liquid to be filtered through a membrane that impedes that flow of the solid material whilst allowing the fluid to pass through it. Over time, solids build up on the membrane, thereby impeding the flow of the fluid through the membrane. Eventually the flow of fluid through the membrane may cease completely.
  • a filter membrane needs to be cleaned by either a method of removal or by back flushing/cleaning. This results in unnecessary “down-time” which can become a significant cost.
  • Some mechanisms are known that employ a moving member that passes over the surface of a filter in a way that provides a cleaning mechanism while in use. Mechanisms such as these comprise large numbers of moving parts which can result in increased maintenance, costs and chance of breakdown.
  • a filtering device that provides a useful alternative to those already known in the industry. It would be an advancement in the art to provide a filtering apparatus that can filter fluids whilst they are pumped from one location to another. A further advancement would be the provision of a filter able to be set to continually self-clean without stopping the flow of fluid through the filter.

  • the filtering device further comprises a pump, adapted to pump fluids and solids to the filter member inlet.
  • the outlet valve is adapted to operate in an open position or a closed position, whereby in the closed position, solids and fluids may pass through the valve and in the closed position the flow of solids and liquids is impeded.
  • the filter member is of substantially circular cross section.
  • the filter member may preferably be provided with a support device to retain the shape thereof.
  • the support device may be provided in the form of a screen mesh.
  • the support device may be provided in the form of support rods.
  • the filter member is provided in the form of a woven hose.
  • the woven hose may be comprised of monofilament fibres, multifilament fibres or a combination of monofilament and multifilament fibres.
  • the filter member may be in the form of a multifilament polyester synthetic yarn with warp of about 12.1 strands per 2.5 cm and weft of about 10.2 strands per 2.5 cm.
  • the filtering device of the present invention has particular application in the filtering of slurries.
  • the slurries may comprise solids contents from 0 % to a maximum % determined by the pumping capacity of the pump of the filtering device.
  • the length of the filtering device is between 24 and 100 m.
  • the filter member inlet comprises a valve, adapted to vary pressures within the filter member and the housing.
  • At least one of the or each housing outlets has provided therein a valve, adapted to be able to vary pressures within the housing.
  • each of the housing outlets have a valve provided therein.
  • the filtering device is further characterised by an inlet manifold and an outlet manifold, the inlet manifold being in fluid communication with the filter member inlet and the outlet manifold being in fluid communication with the filter member outlet.

  • Feed Pressure 320 kPa (average) % Solids: 48.9 % (average) SG of Solids: 3.8
  • the feed pressure fluctuated between 270 - 350 kPa with corresponding flow rates from 115 - 185 L/min.
  • the line pressure was, on average, higher than obtained during laboratory tests (Examples 1 and 2).
  • the filtrate flow was around 5 L/min over the 24 m pipe length compared with 50 L/min over 96 m of pipe length for the laboratory trial of Example 1. This represents a lower flow rate/m of pipe length despite a feed pressure that was double the laboratory pressure. This could arise from a finer particle size in the solids treated but at a p80 of 120 ⁇ m this would not be expected to be a problem although the % passing 38 ⁇ m was over 50 %. A finer particle size of solid would give a higher cake resistance and hence a lower filtration rate.
