Abstract: The present invention relates to a rotary pressure filter comprising a filter drum, a housing, and at least one separating element which divides a process chamber in a gas-tight manner into a plurality of process portions. A sensor is arranged on the side of at least one separating element that faces the housing. The sensor comprises a coil and a rod which is arranged inside the coil. The rod is designed to be displaced in the coil on the basis of a change in the distance of the separating element from the sensor. The invention further relates to a method for detecting wear of a separating element of a rotary pressure filter.

Abstract: The present invention relates to a rotary pressure filter, comprising a filter housing, and a filter drum, wherein a plurality of treatment zones comprises at least a suspension insertion zone and a discharge zone, wherein the rotary pressure filter is configured such that a pressure being present in the suspension insertion zone is higher than a pressure being present in the discharge zone, and that, each time a filter cell, coming from the discharge zone and containing gas having the discharge zone's pressure, enters the suspension insertion zone, the pressure of the suspension insertion zone drops, characterized in that the rotary pressure filter further comprises equipment that is configured to reduce and/or to slow the pressure drop of the pressure in the suspension insertion zone each time a filter cell coming from the discharge zone enters the suspension insertion zone.

Abstract: The invention relates to a rotary pressure filter module (100) which comprises a rotary pressure filter (200) having a plurality of supply lines (302, 318, 330) for supplying a suspension, washing medium, drying medium, and optionally other operating media to be filtered and having a plurality of discharge lines (314, 326, 348) for discharging mother filtrate, washing filtrate, and filter cakes, different sensor devices (306/308/310, 322/324, 334/336, 316, 328, 349) being assigned to the supply lines and the discharge lines, and adjusting devices also being assigned to the supply lines, the rotary pressure filter module (100) additionally comprising a control device (400) which is connected to the sensor devices and the adjusting devices.

Abstract: A rotary pressure filter, comprising a filter drum and a housing. A sensor is attached to the housing and emits light through a light-permeable section of the housing in the direction of a filter cake. The sensor receives light reflected from the filter cake through the light-permeable section of the housing. A processing unit compares properties of the emitted light with those of the received light and determines an absolute thickness of the filter cake and/or a change in the thickness of the filter cake over a pre-determined time. The invention further relates to a corresponding method.

Abstract: A device for tensioning a stuffing box packing includes a plurality of clamping elements, which press a stuffing box gland against the stuffing box packing and thus press the stuffing box packing against a superordinate assembly. At least two clamping elements are connected in a torque-transmitting manner such that rotation of one of the clamping elements causes rotation of the other clamping element or elements.

Abstract: The invention relates to a rotating filter system, comprising a filter housing (110, 210, 310) and a filter rotor (112, 212, 312) which can rotate therein, having filter cells (136?, 136?) with inserted filter means (138) provided in the rotor casing unit (128) thereof in order to filter out the proportion of solids as a filter cake (FK), for instance, from a suspension supplied thereto and in order to evacuate the filtrate via discharge lines (142, 242). The filter rotor (112, 212, 312) can be driven by a drive motor (154b, 254b) via a gear unit (154, 254, 354) with at least one output member (154d, 254d) which is connected to the filter rotor (112, 212, 312).

Abstract: A sealing cord (10) for sealing shafts (14) or other movable machine and equipment parts includes a core (24) having an elastically deformable hollow section (26), the hollow section (26) comprising at least one chamber (26), and a braiding (28) surrounding the core (24). The at least one chamber (26) is equipped with at least one connection (30) for the supply and/or discharge of pressurized fluid (32).
