Lateral dispersion filter basket
View Patent ↗A lateral dispersion filter basket provides turbulence at the bottom of the filter basket reducing strain on the bottom seam of the filter bag disposed therein causing the particulate being filtered to move up along the vertical walls of the filter bag.
1. In a pressurized filter system for filtering fluids, wherein the fluid to be filtered flows under pressure through an input port of a filter vessel housing, having a filter basket adapted to be received by said filter vessel housing and a filter bag adapted to be inserted into said filter basket, said fluid flowing out of an output port disposed proximate a bottom of said filter vessel, each of said basket and said bag having perforated vertical walls and a perforated bottom portion, the improvement comprising:
(a) a hollow, imperforate, hemispherically-shaped insert having an open end, said insert being fabricated from solid material free of apertures and disposed within said filter basket adjacent said basket bottom portion with said open end extending upwardly,
wherein the insert is configured to cause turbulence at the bottom portion of the filter basket to reduce strain on a bottom seam of the filter bag and causing particulate being filtered to move up along the vertical walls of the filter bag.
2. A pressurized filter system, according to claim 1 , wherein said filter bag includes heat welded seams, said seams being inserted into said filter basket in an inverted manner so that said seams extend inwardly.
3. In a filter system for filtering fluids, wherein the fluid to be filtered flows under pressure through, an input port of a filter vessel housing, having a filter basket adapted to be received by said filter vessel housing and a filter bag adapted to be inserted into said filter basket, said fluid flowing out of an output port disposed proximate the bottom of said filter vessel, the improvement comprising:
(a) said filter basket is fabricated with circumferentially extending vertical walls and a bottom having a plurality of apertures disposed through out;
(b) a hollow, imperforate, hemispherically-shaped insert having an open end, said insert being fabricated from a hollow solid material free of apertures disposed, with its open end extending upwardly, at the bottom of said filter basket; and
(c) said filter bag having heat-welded seams, said seams being inserted into said filter basket in an inverted manner so that said seams extend inwardly,
wherein the insert is configured to cause turbulence at the bottom of the filter basket to reduce strain on a bottom heat-welded seam of the filter bag and causing particulate being filtered to move up along the vertical walls of the filter bag.
4. In a pressurized filter system for filtering fluids, wherein the fluid to be filtered flows under pressure through a top input port of a filter vessel housing, having a filter basket adapted to be received by said filter vessel housing and a filter bag adapted to be inserted into said filter basket, said fluid flowing out of a bottom output port disposed proximate a bottom of said filter vessel, each of said basket and said bag having perforated vertical walls and a perforated bottom portion, the improvement comprising:
(a) a hollow, imperforate, hemispherically-shaped insert having an open end, said insert being fabricated from solid material free of apertures and disposed within said filter basket adjacent said basket bottom portion with said open end extending upwardly,
wherein the insert is configured to cause turbulence at the bottom portion of the filter basket to reduce strain on a bottom seam of the filter bag and causing particulate being filtered to move up along the vertical walls of the filter bag.
