Definitions

  • a Filters function is to protect the pump and to stop contaminants going into the pump impeller and clogging up the pump possibly stopping the pump or causing damage to same,
  • the invention relates to a filter for use in conduits or fluid systems,
  • the invention relates to a unitary, metallic or non-metallic or (could be if a specific job requires it a metallic stainless steel or other none ferocious metal filter),
  • the filter comprises of a bousing and a removable perforated filter that allows fluid to flow through the perforations (and thus through the conduit or system), while preventing material or build up that is larger than the diameter of the perforations from continuing through the conduit or fluid system, The material that is prevented from continuing through the conduit or system builds up in the filter and must be removed or it would prevent or restrict flow through the filter, Because the filter is removable, it can be readily emptied of this build up and placed back into the filter container,
  • a filter is used in conjunction with a fine particle filter usually a sand filter or an inline fine filters
  • a fine particle filter usually a sand filter or an inline fine filters
  • Filters are also often used in industry to protect pumps, nozzles, valves, heat exchangers, and other expensive equipment from harmful flow contamination by trapping dirt and foreign matter
  • the filter is close fitted to the filter housing so where the filter is close to the outlet pipe the area all around the pipe quickly gets clogged with solids when this happens it reduces the flow of the fluid considerably,
  • a filter for use with a fluid pump having a base and side wall, it has a portion of the side wall that is concaved and traverses up the side and can run up to the full height of the filter such that in use the filter has an area stepped away from the outlet pipe and the side wall of the filter holder, such as in use a concaved portion extends upward from the bottom of the outlet pipe side of the filter and ean terminate at the top of the outlet pipe side of the filter at the rim,
  • the invention filtration can run up to the full height of the filter due to having a an inversion this cause a Concave/Convex tube possibly running the full height of the filter basket on the outlet pipe side of the filter thus creating a much larger surface filter area the Concave/Convex tube then being further away from the outlet pipe and the surface area of the filter holder on the internal wall of the filter holder will allow a lot more debris into the filter meaning it can go longer between cleaning the filter but without reduction of pressure, flow of fluid or performance of the pump, not as most of this type of filters are normally a close fit or touching all around the shape of the filter to the filter holder, this means just a few leaves or dead insects or solids getting sucked in and stuck over the filter covering the area over the outlet pipe will cause it to become blocked (usually the size of the effective area of the filter is no more than the diameter of the outlet pipe) this invention at the moment does not have to have a handle but it can be incorporated if required,
  • the invention maybe moulded as a single, in a two piece non-metallic unit to make it easier to clean
  • the filter can also be made in stainless steel or a brass material along with many other types of metals or plastics and can be made in any size from micron filters to millimetre filters the filter fits snuggly into the filter holder so even though virtually alt filters on the market are of an open net basket style all-round the way the filter allows fluid to pass through it and acts as a filter, the rest of the filter is touching the filter holder so very little fluid passes between the filter and the filter holder the fluid has to pass from the inlet pipe directly to the outlet pipe,
  • FIGURE 1 A first figure.
  • FIGURE 2 A top view showing the close fitting internal Filter 2 and the darker circle being Filter holder 1, With 2 and 1 being so close this will only allow a very small amount of fluid to pass through the filter/strainer wall 2 virtually all the fluid has to pass from the inlet Pipe being 4 through the internal Concave/Convex filter tube 3, then out through 5 being the outlet pipe, the Concave/Convex tube filter/strainer 3 running the whole height and being stepped away from the filter holder it will filter all the debris out of the fluid for a much longer period and far more efficiently:
  • the filter shown is of a complete open net/filter style, but this can be a solid style body as the filter/strainer is close fit to the filter holder 1 (see FIGURE 1) and fluid will not pass anywhere except from the entry pipe 4 (see FIGURE 2) and on through the Concave/Convex filter 3 and then on to 5 (see FIGURE 2) the outlet pipe, the image also shows quite clearly the top sealing rim 6, the bottom or base of the filter 7 is enclosed and is all part of the same single moulding and can be a net/filter style to help keep down the cost or of solid construction same as the body it is generally cheaper to make them out of net/f ilter style as it uses less material, 9 the top of the Concave/Convex tube is enclosed to cover the filter to stop debris going over the top of the Concave/Convex tube and getting into the pump, this should be a solid top and a part of the top moulding of the filter,
  • the filter housing is on a vertical plane thus making sure the filter housing always remains full of fluid (Figure 1 item 1), It is fed from an inlet tube (Figure 1 item 4) just above centre height to the side of the housing and exits from an outlet tube (Figure 1 item 5) just above centre height on the opposing side of the housing, thus not allowing air into the impeller of the pump,
  • the top of the filter housing ( Figure 1 item 8) which is not my design it is a twist to lock & unlock system normally with a transparent window allowing easy access into the unit to remove the filter for cleaning,
  • the WO 00/18487 filter basket is a CONICAL design with the fluid flowing in through the top of the cone area and out through the base of the unit,
  • This design is a CONCAVE/CONVEX design taking up the full height of the filter (figure 1 item 3) and wider than the outlet pipe, giving maximum filtration and allowing maximum flow of fluid, through the side outlet pipe (Figure 1 item 5) of the basket housing this gives a much larger filter surface area and means there are less working hours lost as it takes longer for the solids to block up this filter, over other standard filters of this type currently on the market,
  • Concave Origin: late Middle English: from Latin concavus, from con- 'together' + cavus 'hollow' concave)

Abstract

La présente invention concerne un filtre pour utilisation avec des pompes à fluide, le filtre ayant une base et une paroi latérale, de sorte qu'une partie de la paroi latérale soit rendue concave, de sorte que l'aire de filtration ainsi que la distance entre le filtre et un tuyau de sortie soient augmentées, afin de réduire le blocage.
