Abstract:
An extension attachment kit for a filter housing, said filter housing including a cylindrical housing delimited by an open, top end and a closed, bottom end, said bottom end including an inlet fluid distribution tube extending upwardly to said top end of said housing, said inlet distribution tube including a plurality of openings therein for introducing a fluid to be filtered into said housing, said extension attachment kit comprising:an open casing defined by a vertical cylindrical side wall having an open top end and an open bottom end, said bottom end removably and sealably connected to said top end of said filter housing, said top end terminating with an annular collar thereabout, said collar having an inside surface and a top surface, said inside surface including an undercut therein for providing an inner circumferential shoulder;a removable cover for sealably closing said open top end of said casing, said cover in resting contact against said top surface of said collar;an elongate filter basket formed from a perforated cylinder having a first closed end and a second open end, said first closed end comprising a planar plate having a centrally disposed hole therein, said second open end delimited by an annular lip extending away from said cylinder, said filter basket slidably received within said casing and said filter housing wherein said inlet distribution tube projects though said central hole such that said planar plate is in close proximity to said bottom end of said housing and said annular lip rests on said inner circumferential shoulder of said collar;an elongate, disposable filter bag inserted within said filter basket, a bottom of said filter bag having a centrally located opening such that said filter bag bottom is slid over said inlet fluid distribution tube, an open top of said filter bag in resting contact against said annular lip of said filter basket; anda means for holding said casing and said filter housing together at a point of connection, wherein said inlet distribution tube extends upwardly to about said connection point so as to provide an area above said inlet distribution tube which causes a continuous vibration in said filter housing and casing, thereby resulting with a continuous shaking of said filter bag so as to loosen impurities entrapped on said filter bag.
