Definitions

  • the present invention generally relates to a treatment system for drainage systems.
  • the invention provides a means whereby debris entering a drain is collected for easy removal therefrom.
  • a common problem associated with drainage systems is the tendency for debris to collect in the drainage system, resulting In blockages. Once the drain becomes blocked the area around the drain floods. This can be extremely hazardous, particularly where traffic is involved.
  • 'debris is taken to mean any item entrained in a liquid. Typically this would mean leaves, branches, rubbish and sand but in some applications can also include chemical pollutants.
  • the present invention provides a treatment system for minimising debris entering a drainage system
  • the treatment system comprises: a support housing which is supportingly received in the drainage system downstream of an opening of the drainage system, the support housing comprising a first drainage means for allowing liquid to flow therethrough; an first insert for collecting debris, the first insert comprising a second drainage means for allowing liquid to flow therethrough whilst preventing the flow through of debris, the first Insert being removably supported within the housing such that when in place the first drainage means and second drainage means align, allowing liquid to pass through the treatment system; wherein the debris collected in the treatment system is removed therefrom by removing the first insert from the support housing.
  • the treatment system of the current invention enables collection of the debris from the liquid passing into the drainage system but also allows the debris to be removed from the treatment system without the need of a vacuum or other machinery.
  • the treatment system can quickly be cleaned by removing the first insert and then placing a new one In its place.
  • the debris in the first insert can be discharged into a bin and then the first insert may be placed back into the support housing.
  • the support housing may comprise a first housing for receiving the first insert, and a securing means to removably support the treatment system relative to the drainage system.
  • the first housing may be tapered inwardly such that an opening of the first housing is larger than the bottom thereof.
  • the first housing may support one or more fixings to which the first insert may be fixed.
  • the fixings may be in the form of brackets located on the inner surface of the first housing.
  • the entire first housing provides the first drainage means.
  • the first drainage means is in the form of a mesh material.
  • the first housing may be formed from the mesh material.
  • the first drainage means is formed of perforated sheet metal.
  • the first housing may be formed from the perforated sheet metal.
  • the support housing may be received within the opening of the drainage system.
  • the securing means comprises two or more arms extending upwardly from the first housing.
  • the distal end of each arm may have an outwardly extending projection adapted to engage a surface of the drainage system.
  • the surface may be the surface upon which the grate is supported when the grate is in place over the drain opening.
  • the securing means is provided by the top portion of the first housing.
  • the top portion may extend outwardly such that it is adapted to engage the surface upon which the grate is supported when the grate is in place.
  • the support housing may also comprise a second housing.
  • the second housing may be located below the first housing such that in use it is downstream therefrom.
  • the second housing may have a third drainage means. Preferably the entire second housing provides the third drainage means.
  • the third drainage means is in the form of a mesh material.
  • the second housing may be formed from the mesh material.
  • the third drainage means is in the form of perforated sheet metal.
  • the second housing may be formed from the perforated sheet metal.
  • the entire first insert provides the second drainage means.
  • the first insert may be formed from a porous woven material, the material being selected according to the minimum sized particle which is to be separated from the liquid.
  • the first insert may be snugly received within the first housing.
  • the first insert may be tapered. By having the first housing and first insert tapered, the first insert may easily be removed from, and inserted into the first housing.
  • the first insert may be slightly shorter than the first housing. This will allow liquid flowing into the drain to bypass the first insert in the event that the first insert is full of debris.
  • the first insert may have one or more handles to allow easy removal of the first insert from the first housing, Each handle may be located on the bracket of the first housing. This will ensure the walls of the first insert remain adjacent to the wall of the first housing, preventing the first Insert from collapsing and therefore not effectively collecting debris as it passes into the drainage system.
  • the treatment system may also comprise a second insert which may be received in the second housing. When in place the second insert may be located below the first housing.
