Filter device, in particular for high-pressure applications in a molten polymer filtration
First Claim
1. A filter device, comprising:
- a first module including a screw-in component with a first threaded section for mounting the filter device and with a second threaded section, including a perforated supporting tube fixedly attached to and extending from said screw-in component at a first axial end of said supporting tube, and including volume displacement component fixedly attached to said supporting tube at to a second axial thereof to form an integral component end of said supporting tube; and
a second module including a metal wool filter medium, including a support grid enclosing said filter medium and including first and second fixing components retaining and fixed to said support grid and said filter medium and spaced from one another by said support grid and said filter medium, said first fixing component being threadedly coupled to said second threaded section of said screw-in component, said second fixing component forming a handle for manipulating the filter device and encircling said volume displacement component, said filter medium encompassing and being supported on an interior thereof by said support tube.

Abstract
A filter device, in particular, for high-pressure applications in a molten polymer filtration, has a screw-in piece (10), provided with a first threaded section (12) for fixing the filter device, and a second threaded section (14) for fixing a filter medium (16), in particular, in the form of a metal wool and with a perforated support tube (18) for the metal wool. The other free end of the filter device is provided with a volume displacer (24). The metal wool is surrounded by a support grid (20) and fixed by two fixing pieces (28, 30), held at a separation from each other by the support grid (20). One fixing piece (28) is fixed to the second threaded section (14) of the screw-in piece (10). The other fixing piece forms a handle (30) for the fixing formed. As a result of the volume displacer (24) being a one-piece component of the support tube (18) and the fixing piece (30) forming the handle covering the volume displacer (24), the filter device is significantly improved in that a simple and rapid assembly procedure for the exchangeable filter medium is provided. Also, the filter element construction is held formed to be free of damaging torsional loads.
