BRIEF DESCRIPTIONS OF THE DRAWINGS
[030] Figure 1 is a schematic view and in part a see through or part cross section view of the debris filter arrangement for separating solid waste from fluid in a preferred embodiment of the invention.
[031] Figure 2 is a schematic representation of a further preferred embodiment of the invention for the debris filter arrangement.
[032] Figure 3 is a schematic representation showing a further preferred embodiment of the debris filter arrangement for this invention. DETAILED DESCRIPTION OF THE DRAWINGS
[033] Figure 1 shows a preferred embodiment of the invention wherein the debris filter arrangement (10) includes a main body (12).
[034] The main body (12) has an inlet (14) through which flowing fluid containing solid waste is passable there through inlet (14) shown by way of arrow (15).
[035] In the preferred embodiment shown in Figure 1 for the debris filter arrangement (10) the plurality of blades (21) are rotatably supported by way of the rotatable shaft (20) with arrows (7) showing direction of rotation.
[036] The debris filter arrangement (10) includes a first discharge outlet (16) which is separate from the inlet (14) of the main body (12) of the debris filter arrangement (10) by way of the filter screen (24).
[037] The filter screen includes a multiplicity of apertures best described as a network or series of perforated holes shown as (25).
[038] The second discharge outlet (18) is accessible without having to pass through the filter screen (24).
[039] As is to be envisaged, fluid containing solid waste such as water containing rubbish, would enter the inlet (14) where that flowing fluid would send the plurality of blades (21 ) into rotation with the fluid being able to pass through the perforated holes (25) of the filter screen (24) and with the solid waste then being guided or scraped along through by the plurality of rotating blades (21) along the filter screen (24) out through the second discharge outlet (18) shown by way of arrow (27) wherein the now filtered fluid having had the rubbish separated is free to exit the first discharge outlet (16) shown by way of arrow (28) having passed through the filter screen (24).
[040] A greater understanding of the invention can be further understood by referring to the preferred embodiment shown in Figure 2 wherein the debris filter arrangement is shown generally as (30).
[041] The debris filter arrangement (30) includes the main body (32) having the fluid inlet (31) which would be able to communicate there through fluid containing solid waste into the main body (32) of the debris filter arrangement (30).
[042] The main body (32) also includes the fluid outlet (33) however fluid entering through the inlet is only able to get to the discharge outlet (33) by first passing through the filter screen (39) by way of a multiplicity of apertures (41 ).
[043] As the solid waste that enters with the fluid through the inlet (31), shown by way of arrow (47) is not able to pass through the multiplicity of apertures (41) of the filter screen (39), the rotating blades or baffles (36) on a drum roller (34)rotate around pushing, or guiding, the solid was waste past the filter screen (39) for the rubbish to drop out into the discharge outlet (35) shown by way of arrow (45).
[044] Hence the fluid has exited the debris filter arrangement shown by way of arrow (43) and the rubbish has been separated from the fluid which entered through inlet (31) as rubbish shown as arrow (45).
[045] It is well illustrated in Figure 2 in that the plurality of blades (36) are almost nested in close proximity to the filter screen (39) and as they rotate they define a circumference where that circumference also then matches the curvature of the filter screen (39) so as to assist the scraping or guiding of the solid waste contained within the fluid that has entered through the inlet (31) of the main body (32) shown by way of arrow (47) to be pushed along out past the filter screen (39) and by way of the guide (49) can then drop down to exit as rubbish from the discharge outlet (35) again shown by way of arrow (45).
[046] Hence the fluid entering the inlet (31) passes through the multiplicity of apertures (41) of the filter screen (39) to exit out the discharge outlet (33) with the solid waste separated through the action of the rotating blades (36) which pushes the solid waste along the filter screen (39) but as the multiplicity of apertures (41) are not large enough for the solid waste to pass therethrough, this solid waste as introduced above, is either scraped or swept along and then guided ultimately out through the discharge outlet (35) without having to pass through the filter screen (39).
[047] It is easy to envisage with Figure 2 how the momentum flow of fluid containing solid waste entering through the inlet (31) can flow down upon the plurality of blades (36) and send the plurality of blades (36) into rotation and then to sweep the rubbish so the rubbish (solid waste) is moved away from the filter screen (39) through a simple mechanical action relying on gravity and the momentum of flow of the fluid containing the solid waste entering through inlet (31) of the main body (32) of the debris filter arrangement (30).
[048] Figure 3 shows a further preferred embodiment wherein the debris filter arrangement (50) is consistent with the structural features of the debris filter arrangement (30) shown in Figure 2, however provides an example as to how fluid containing solid waste can be drawn into the debris filter arrangement (50) which in the embodiment shown in Figure 3 is through a screw feed arrangement (62).
[049] The screw feed arrangement (62) would be positioned within a particular waterway requiring separation of solid waste from the water, and the screw feed arrangement (62) would be configured and orientated to be able to draw up the fluid containing solid waste and as shown by arrow (55) is able to be introduced into the main body (51 ) of the debris filter arrangement (50).
[050] The flowing fluid including solid waste shown by way of arrows (55) engages with the filter screen (52) in part because of internal structural arrangements within the main body (51) of the debris filter (50) through the use of structural guides such as that shown as (61) in Figure 3 but as with embodiments discussed in Figures 1 and 2, the fluid is able to pass through the filter screen (56) as it includes a multiplicity of apertures so that the exiting fluid shown by way of arrows (56) can then be discharged out through the outlet (53) of the main body (51) shown by way of arrows (77).
[051] While the fluid now filtered exits the outlet (53), solid waste contained in that original fluid entering the main body (51) is pushed along by way of the rotating plurality of blades (64) where it is then swept on to guide (60) and then the momentum of being paddled forward by the blade (64) and/or gravity flow, has the waste shown by way of arrows (58) existing through the discharge outlet (54) into a waste container (59).
[052] Figure 3 shows use of the screw fed arrangement for drawing the fluid with the solid waste from the waterway into the debris filter arrangement (50) however this invention is not limited to any one particular means for introducing the fluid containing the solid waste into the debris filter arrangements and could equally include alternative methods such as through the use of suction pumps and the like, gravity, hydraulics and air compressors.
