摘要： The invention relates to a filter device, comprising a plurality of filter elements (21), which can be received in a filter housing having a filter inlet for a fluid to be filtered and a filter outlet for the filtered fluid, wherein flow through the filter elements (21) is possible in both directions for filtration or backwashing. Because the shut-off element (41) is a fast-closing plate valve (43), which can be actuated by means of a hydraulic piston (53) and blocks the fluid connection mentioned above so quickly that a feeding effect is created in the manner of a pressure blow on the backwashed filter element (21), said feeding effect increasing the cleaning of pollution on the filter element (21), an improved backwashing cleaning is achieved.

摘要： The invention relates to a separating device, particularly for separating solids from liquids, preferably from the quantity of reverse flow of a reverse flow filter system. The separating device comprises: a spinning screen provided in the form of a drum screen (17) having an annular screen wall (21); a spray tube (15), which supplies the liquid to the drum screen (17) and which, with regard to its opening (26) to the inside of the screen wall (21) of the drum screen (17), extends in an at least approximately tangential manner thereto in order to produce a spinning flow of the liquid on the screen wall (21); a housing (19) that surrounds the drum screen (17) while serving to hold the liquid passing through said screen wall (21), and; an exit (29) located at the bottom (27) of the drum screen (17) while serving to discharge the separated substances.

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.
