摘要： A process for production of conical filter elements, in particular slotted tube filter elements, includes forming a support structure of a plurality of support rods around which is wound at least one wire profile in individual turns. Slots are left clear in the wire profile through which a fluid may pass. The wire profile is, at least in part, rigidly connected to the support rods and is enclosed in a screen grid. The screen grid, at least in part, rests against the wire profile, follows to the same extent the conical path of the filter element, and is provided on its ends with end components. Since the conical screen grid is in the form of a one-piece pull-on part fitted on the support structure and since the pull-on part is designed to be longer than the support structure, after the screen grid has been pulled onto the support structure, at least one projecting length of the screen grid may be separated for precision fitting and is connected to the respective end component of the filter element. The screen grid may be produced integrally with the remaining filter element in advance of the connection process and subsequently pulled onto the support structure with wire profile like a stocking.

摘要： A method for producing a sealing connection between a filter mat of a tubular filter element and a metallic head piece encircling the filter element at one end. The head piece has an annular groove accommodating the edge of the filter mat. In order to reduce the internal diameter of the annular groove, the wall adjacent to the periphery is compressed by the periphery of the head piece towards the interior by applying a force of pressure which is directed radially towards the interior. The wall of the annular groove adjacent to the periphery is provided with an enlargement which enlarges the diameter of the head piece. The force of pressure for compressing the wall is applied in the area of said enlargement.

摘要： A filtering device for a spinning head for producing plastic threads. The spinning head has a housing in which the plastic melt flows through a filter element under pressure before exiting the spinnerets. The filter element is provided with a filtering material that is subjected to an axial contact pressure through a distributor device, according to the degree of pressure of the melt. This contact pressure acts upon the sealing edges of the filter element to close the sealing gaps. The special geometrical configuration of the filter element and/or its elasticity guarantee advantageous filtering in terms of energy. The filtering system is resistant to pressure and provides good, permanent sealing.

摘要： 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.

摘要： 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.

摘要： A filter apparatus deposits impurities from a fluid stream by use of a filter element (10) accommodated in a filter casing (12). The filter casing (12) has a swirl space (14) such that the fluid stream to be filtered is conducted at least partly in a swirling flow around the filter element (10). The properties of a cyclone are utilized for the actual filtration operation to the extent that the swirl space of the filter casing brings about multiple deflection of the direction of motion of the fluid to be filtered.

摘要： The present invention relates to a process for regenerating adsorbers as used in solvent recovery, for example. Regeneration is effected in that the adsorbed substances are desorbed according to known processes and a gaseous desorbate stream is produced, that the gaseous desorbate stream is fed into one or several pervaporation modules, that the desorbed substances in the pervaporation modules are removed from the desorbate stream by gas permeation via semi-permeable solubility diffusion membranes, and that the reduced desorbate stream is recirculated to the adsorber. Preferred embodiments of the process according to this invention use heatable solubility diffusion membranes. A recovery of the desorbate stream is rendered possible by the process according to this invention, which does not imply a change in state of the entire desorbate stream.

摘要： A filtering apparatus has a plurality of filtering elements (9) in a filter housing (1), a filter inlet (45) and a filter outlet (43). During the filtration operation, one of the filtering elements (9) can be back-flushed by a back-flushing device (13, 21). The back-flushing device has a pressure control device (13) including a hydraulic accumulator (13). One accumulator fluid chamber (67) can be filled during the filtration operation with a quantity of filtered fluid and can be connected for a back-flushing operation via a back-flushing guide (21) to the clean side (59) of the filtering clement (9) to be cleaned. Another accumulator fluid chamber (79) can be subjected to a media pressure.
