Definitions

  • This invention relates to a self cleaning filter such as may be used in an irrigation system.
  • U.S. Patent No. 4060483 discloses a method and apparatus for effecting the cleaning of a fluid filter by a hollow filter cleaning body having an inlet situated in close proximity to the filter member, the flow of water through the cleaning body causing movement of the cleaning body, the cleaning water then flowing through an exhaust port.
  • a self cleaning filter unit having a liquid inlet and a liquid outlet, a filtering member disposed between said filter inlet and filter outlet, an exhaust outlet, means disposed within said filter unit for
  • FIG. 1 is a longitudinal cross-sectional view 25. of the invention, the filter cleaning element not being sectioned, and
  • FIG. 2 is a cross-section on the lines 2-2 of FIG. 1 on an enlarged scale
  • the filter unit can comprise a generally cylindrical casing 1 having an inlet 2 and socket 3 toward one end and 5. an outlet 4 and socket 5 toward the other end. Within the casing there is disposed a cylindrical filter element 6, the element being mounted in rings 7 which are sealed by sealing members 8 to the interior of the cylindrical casing 1.
  • the cylindrical filter element 6 is mounted in rings 7 which are sealed by sealing members 8 to the interior of the cylindrical casing 1.
  • element 6 is positioned such that the fluid will flow in through the inlet 2 into the interior of the casing at that end and then through the interior of the filter 6, and after passing through the filter element 6 is discharged through the outlet port 4.
  • the inlet flows from the inlet 2 through a course prefilter portion 6a into the interior of the filter 6.
  • the cylindrical casing 1 at the inlet end is closed by an end cap 9 provided with suitable
  • sealing rings 10 the cap being maintained in position by a longitudinal rod 11 passing through the filter unit to be secured to the end cap 12 at the outlet end of the filter unit.
  • This second end cap is provided with an exhaust outlet 13 and sealing rings 10, with
  • the rod 11 supporting on a bush 14 and thrust bearing 15, a water turbine 16 between the end cap 12 and the adjacent ring 7.
  • the water turbine 16 has two arms 17 extending radially, each arm having an aperture 28 so that the water is discharged tangentially to 30. cause the turbine to rotate.
  • the hollow member 17 surrounding said rod and extending through the filter element and supported on the rod 11 by a bush 18 at the ring 7 adjacent the inlet 2 to the casing 1.
  • the hollow member 17 is shaped to have a portion 19 adjacent to the inner surface of the filter 6, where the member 17 is provided with a series of slits, 5. holes or apertures 20.
  • the hollow member 17 is also provided with a longitudinal brush element 21 pivoted from the hollow element by suitable arms 22 or the like. The brush element is adapted to contact the interior of the filter element during the cleaning 10. of the filtered material therefrom.
  • the arms 22 are pivoted in brackets 30 attached by screws 31 to the hollow element 17, the brackets 30 having an upstanding flange 32, the arms 22 passing through holes in the flange 32 in a pivotal manner. 15.

  • a drive housing 23 surrounds the turbine 16, 20. and has a radial wall 24 and a sealing ring 25 to seal the turbine drive area from the filter area except through the hollow member 17.
  • the exhaust 13 can be provided with a suitable flow control, and in normal operation of the filter
  • the brush is pivoted to the cleaning element so that it protrudes away from the cleaning element and is biassed by the spring to the retracted position away from the filter element when the filter element is not being cleaned. This is to ensure that the
  • the resistance of the spring is such that it 25. holds the brush in the retracted position, but when the hollow element is rotated, the resistance to movement created by the water causes the brush to pivot into contact with the filter element against the bias of the spring.
  • the spring tension is adjusted so that this occurs, with the spring returning the brush to its retracted position when rotation ceases.
  • the hollow element may have a plurality of apertures therein to allow the water to flow there- 5. through, or could have a longitudinal slit or plurality of slits, which slits can be positioned in relation to the filter and the brush so that as the element and brush rotate the disturbed filtered material and debris would immediately be swept through the 10. slit.
  • the control of the filter unit by the valve positioned in the exhaust aperture or in the exhaust line can be manually operated or alternatively be con ⁇ trolled automatically either by sensing the back 15. pressure in the filter, or alternatively be controlled by a timer or some other control such as the quantity of water which has passed through the filter.
  • valve One suitable form of valve is that s'hown in Australian Patent No. -5-08284 entitled “Automatic 20. Filter Backwash Control”.
  • the filter element with its sealing rings and the hollow member and the turbine can be readily assembled into the outer cylindrical casing through the ends of the cylindrical casing and are retained 25. in positon by the longitudinal rod and the end caps. It will be realised that various forms of water turbines can be provided, that is being either the reaction or impulse type and either operated by way of the use of curved vanes or jets or the like.

Abstract

Un filtre à auto-nettoyage possède un élément creux (17) relié par l'intermédiaire d'une turbine (16) à un orifice d'échappement réglable (13). Le fluide s'écoule dans le filtre (6) et sort au travers de l'orifice de sortie (5) et lors de l'écoulement du fluide au travers de l'échappement (13), la turbine (16) fait tourner l'élément creux (17), des passages de fluide (20) reliant l'extérieur du filtre (6) à l'intérieur de l'élément creux (17). L'élément creux (17) possède un balai pivotant (21) qui se déplace en contact avec le filtre (6), lors de la rotation de l'élément (17) à la suite de la résistance fluide agissant sur le balai (21).
