A filter device includes a filter housing (10), a filter inlet (12), a filter outlet (14), and a filter element (16). The filter element divides a filter area (18) into two partial areas (20, 22). One partial filter areas is conical in form with the cross-section of that partial area (20) being tape
A filter device includes a filter housing (10), a filter inlet (12), a filter outlet (14), and a filter element (16). The filter element divides a filter area (18) into two partial areas (20, 22). One partial filter areas is conical in form with the cross-section of that partial area (20) being tapered from the filter inlet (12) to the filter outlet (14). The partial areas are separated from each other by the filter element. This arrangement results in an optimum residence time distribution inside the filter device at a uniform flow rate, which is particularly useful for highly viscous fluids such as polymer melts or similar.

The invention claimed is: 1. A filter device comprising: a filter housing with a filter inlet and a filter outlet at opposite ends thereof and with an inside filter space; and a conical filter element subdividing said filter space into first and second subspaces arranged sequentially from said filter inlet to said filter outlet, said first subspace tapering conically in transverse cross-section from said filter inlet to said filter outlet, said second subspace widening conically in transverse cross-section from said filter inlet to said filter outlet to provide a uniform flow rate in said first and second subspaces, said subspaces having respective conicities proceeding constantly in opposite directions, tapering of said first subspace and widening of said second subspace occurring to substantially equal extents in that said first subspace extends outwardly and the second subspace extends toward a center of said filter housing with each subspace being bounded opposite said filter element by a cylindrical wall, said filter element narrowing conically from said filter outlet toward said filter inlet. 2. A filter device according to claim 1 wherein said cylindrical wall bounding said first subspace forms said filter housing; and said cylindrical wall bounding said second subspace comprises a rod-shaped filter element extending along a central axis of and inside of said filter housing. 3. A filter device according to claim 1 wherein said filter element comprises a supporting tube and filter material releasably coupled to said supporting tube so as to be replaceable. 4. A filter device according to claim 3 wherein said filter housing, said filter inlet, said filter outlet, said supporting tube and said filter material are formed of steel material. 5. A filter device according to claim 1 wherein said filter housing is cylindrical in an area thereof receiving said filter element. 6. A filter device according to claim 1 wherein said filter inlet and said filter outlet have open cross-sections toward said filter space ensuring a uniform flow rate of fluid to be filtered. 7. A filter device according to claim 6 wherein the fluid to be filtered has a high viscosity. 8. A filter device according to claim 7 wherein the fluid to be filtered is liquified polymer material or a polymer solution. 9. A filter device according to claim 3 wherein said filter housing, said filter inlet, said filter outlet and said filter element are formed of steel. 10. A filter device according to claim 1 wherein said subspaces extend substantially along a full length of said housing between said filter inlet and said filter outlet, and are of substantially equal length. 11. A filter device according to claim 10 wherein said first and second subspaces substantially taper and widen, respectively, along substantially said full lengths thereof. 12. A filter device, comprising: a filter housing with a filter inlet and a filter outlet at opposite ends thereof and with an inside filter space; and a conical filter element subdividing said filter space into first and second subspaces arranged sequentially from said filter inlet to said filter outlet, said first subspace tapering conically in transverse cross-section from said filter inlet to said filter outlet, said second subspace widening conically in transverse cross-section from said filter inlet to said filter outlet for a uniform rate of flow therein to optimize dwell time distribution over said filter element, said subspaces having respective conicities proceeding constantly in opposite directions, tapering of said first subspace and widening of said second subspace occurring to equal extents in that said first subspace extends outwardly and the second subspace extends toward a center of said filter housing with each subspace being bounded opposite said filter element by a cylindrical wall, said filter element narrowing conically from said filter outlet toward said filter inlet. 13. A filter device according to claim 12 wherein said cylindrical wall bounding said first subspace forms said filter housing; and said cylindrical wall bounding said second subspace comprises a rod-shaped filter element extending along a central axis of and inside of said filter housing. 14. A filter device according to claim 12 wherein said filter element comprises a supporting tube and filter material releasably coupled to said supporting tube so as to be replaceable. 15. A filter device according to claim 14 wherein said filter housing, said filter inlet, said filter outlet, said supporting tube and said filter material are formed of steel material. 16. A filter device according to claim 12 wherein said filter housing is cylindrical in an area thereof receiving said filter element. 17. A filter device according to claim 12 wherein said filter inlet and said filter outlet have open cross-sections toward said filter space ensuring a uniform flow rate of fluid to be filtered. 18. A filter device according to claim 17 wherein the fluid to be filtered has a high viscosity. 19. A filter device according to claim 18 wherein the fluid to be filtered is liquified polymer material or a polymer solution. 20. A filter device according to claim 12 wherein said filter housing, said filter inlet, said filter outlet and said filter element are formed of steel. 21. A filter device according to claim 12 wherein said subspaces extend substantially along a full length of said housing between said filter inlet and said filter outlet, and are substantially of equal length. 22. A filter device according to claim 21 wherein said first and second subspaces substantially taper and widen, respectively, along substantially said full lengths thereof.
