An outlet cover with a first attachment pin fixed with respect to the outlet cover and having a radially extendable portion deformable upon by a radial force exerted from a hollow inside of the first attachment pin. The radially deformable portion prevents the first attachment pin from being withdrawn from an associated attachment hole, while allowing the first attachment pin to be compressed further into the associated attachment hole, thereby preventing a securing element from stripping any retaining surface, and thus increasing the longevity of the outlet cover. An associated filter plate, filter plate assembly and a filter are also concerned.

A sealing strip for sealing adjacent filter plate assemblies of a horizontal filter press. The disclosure is based on the idea of providing the sealing strip with a stiffener at a base portion of the sealing strip, positioned such that it intersects with a line running through a ridge provided on a distal portion of the sealing strip and extending along a vertical direction, perpendicular to both the length direction and the width direction of the sealing strip, as seen along the cross-sectional profile of the sealing strip. A filter frame, a filter frame assembly and a filter apparatus having such a sealing strip are also provided.

A filter press for separating solid components from liquid components of a slurry. The filter press includes a compression system coupled to a stationary pressure plate of the filter press. The compression system includes at least one electrically operated compression actuator having a planetary screw assembly, and a transport system coupled to a displaceable pressure plate of the filter press. The transport system includes at least one electrically operated transport actuator having a rack and pinion drive assembly. The compression system rigidly connects to the transport system so as to form, for each respective pair of compression actuators and transport actuators, a common actuator link which extends linearly from the stationary pressure plate to the displaceable pressure plate along the longitudinal dimension. A retrofitting kit for a filter press, a method for replacing an existing compression and transport system for a filter press and a method for controlling a filter press are set forth.

A recessed plate filter press for circularly pulling and pushing plates includes a main beam, a thrust plate, multiple filter plates, multiple filter plate handles, multiple plate pulling devices, a push plate, a depressing frame, a chain and multiple sprockets, the thrust plate is arranged on the main beam, and the multiple sprockets are arranged at both ends of the main beam, the chain is installed on the multiple sprockets, the multiple filter plate handles are arranged on both sides of the multiple filter plates, the multiple plate pulling devices are arranged apart on the chain, and the depressing frame is arranged on the push plate, and a plate pulling hook of each plate pulling device is snap-connected with each filter plate handle.

A filter diaphragm for a filter plate assembly of a recessed plate-type filter, such as a filter press or a tower press. The diaphragm includes a sheet-like body having a flexible structure, and, at least on a side of the body, a plurality of distinct attachment studs to be inserted into corresponding distinct attachment holes of a respective filter plate for attaching the diaphragm to the filter plate. The attachment studs are arranged along a sealing region extending along a periphery of the filter diaphragm and extend in a direction perpendicular to the diaphragm body. The attachment studs are equipped with an opening extending through the filter diaphragm, between the opposing sides thereof. A diaphragm filter plate and -assembly, and filter are also concerned.

A filter plate assembly which is resistant to both wear and deformation caused by creeping, while facilitating maintenance thereof. A filtrate vat is provided that is formed on, and integral with the filter plate, in addition to a separate, replaceable vat liner. In this way, a rigid structure of the filtrate vat capable of resisting deformation may be achieved, while the vat liner separates the filtrate from the filtrate vat and the associated filter plate, providing wear resistance and facilitating maintenance. The present disclosure further concerns the filter plate and the filtrate vat.
