摘要： A filter device has a filter housing (1) having a fluid inlet (8) for unfiltered matter and having a fluid outlet (9) for filtrate, and has at least one one-piece or multi-part filter insert (15, 17) held in the filter housing (1). Filter insert (15, 17) can be cleaned using a backwash device (25) having at least one backwash element (31) in counter flow to the direction of filtration. The backwash element can be moved along the inside of the relevant filter insert (15, 17) by a fluid-conveying drive shaft (29) of a rotary drive (69, 71). The individual backwash element (31) has, at the end adjacent to this inside, at least one gap-shaped passage opening, which extends in parallel to the axis of rotation of the drive shaft (29) and which opens into a flow chamber connected to the drive shaft (29) in a fluid-conveying manner. At least one further backwash device (27) has a further backwash element (31). The fluid-conveying drive shaft (29) is divided into chambers (73, 75) separated from each other. One backwash element (31) of one backwash device (25) is connected to one of the chambers (73, 75). The other backwash element (31) of the other backwash device (27) is connected to another chamber (73, 75).

摘要： A filter device has filter elements (23) received in a filter housing (1) with a filter inlet (19) and a filter outlet (21). Flow passes through the filter elements (23) for a filtration or backwash in both directions. At least one filter element (23) performs the filtration. At least one other filter element (23), for cleaning off its active filter surface, can be backwashed by a backwash appliance. For supporting the backwashing, the appliance contains a pressure control (43) having a pressure control element (45). During a backwash operation, the fluid flow is controllable in a fluid connection between filter inlet (19) and the filter element (23) that is to be cleaned off. The fluid connection has a connection space (29) having element openings (27), each of which can be connected to an open end of the filter cavity forming the unfiltered side of each filter element (23). A fluid pathway (27) is provided via which, during the filtration, unfiltrate flows into the connection space (29). By the pressure control element (45), the flow of unfiltrate through the element opening (27) associated with the filter element (23) that is to be cleaned off can be controlled.

摘要： A filter device for the insertion of filter elements (28) to be positioned in a filter housing (10) having a filter inlet (20) and a filter outlet (22) for the fluid to be filtered. The filter elements (28) are traversed in both directions for filtration or backwashing. Certain filter elements (28) perform the filtration in a filtration position and at least one additional filter element (28) can be backwashed in a backwashing position to clean its active filtration surface. As the individual filter elements (28) are brought into the backwashing position and are then returned to their filtration position in succession by a pivoting device (30), the filter elements are individually displaced into the backwashing position in a temporal sequence, in contrast to prior art, where an arm-type backwashing device is pivoted towards the individual filter elements to carry out the backwashing process.

摘要： A system for gas cleaning has at least one casing (1) with a first chamber (31) into which the gas to be cleaned can be flowed and with a second chamber (33) from which the cleaned gas exits. A filter device (35) can have the gas flow through it and can be arranged between the chambers. The filter device has filter media both for the separation of solid particles and for dehumidifying the gas by separating out coalesced liquid. The system has, upstream of the filter device (35), an arrangement (11, 37) for preliminary dehumidification of the gas.

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.
