A vacuum filter press system may comprise: a frame; a liquid injection system for controllably injecting liquid directly into each of a multiplicity of chambers; a plurality of filter plates configured to form a stack of parallel plates, each of the filter plates being movably attached to the frame and configured to form the multiplicity of chambers, each of the chambers being formed by adjacent filter plates, each of the chambers being lined by filter cloths, wherein the plurality of filter plates, the multiplicity of chambers and the filter cloths are configured to allow water vapor to escape from the chambers while retaining solids from the liquid to form a filter cake; and a vacuum pump connected to the multiplicity of chambers. Furthermore, wherein each filter plate has spacers attached to both sides, for enlarging the width, and hence capacity of the filter chambers.

The invention shows an apparatus for recycling bituminous material bodies by melting, in particular for recycling bituminous composite material bodies comprising a composite material and a bituminous material, in particular roofing materials, in particular in the form of bituminous covering layers of roofing sheets, the apparatus including: a vessel having a vessel wall surrounding an interior space of the vessel extending along a vertical axis of the vessel for receiving the bituminous material bodies, a bottom plate and a compression plate extending transverse to the vertical axis wherein at least the compression plate has a number of through flow orifices adapted to allow a through flow of molten bituminous material, wherein the plates are movable along the vertical axis such that in a first operating state the compression plate is in a middle position for forming a melting space of larger size between the compression plate and the bottom plate for melting bituminous material in the melting space wherein the bottom plate is in a melting position, in a second operating state the compression plate is in a lower position for forming a compression space of minor size between the compression plate and the bottom plate for compressing solid residues and/or solid composite material in the compression space, and
wherein
molten bituminous material is retained in a storing space above the compression plate for storing and/or discharging bituminous material, wherein the bottom plate is in a compression position, wherein the compression plate is movable from the middle position to the lower position.

The present disclosure relates to the extraction of lithium from liquid resources such as natural and synthetic brines, leachate solutions from clays and minerals, and recycled products.

The present invention relates to the extraction of lithium from liquid resources such as natural and synthetic brines, leachate solutions from clays and minerals, and recycled products with the assistance of an alternate phase.

An outlet piece assembly for a horizontal plate and frame-type filter, such as tower press. The disclosure is based on the idea of providing the outlet piece assembly as having a base removably attachable to a filter press (e.g., to the filter plate or plate frame thereof), and a lid removably fixed to the base, such that an internal conduit of the outlet piece assembly running between a vat end and a discharge end is formed between the base and the lid. This enables a part of an associated filtrate vat component, such as the vat liner, to be received between the base and the lid, thereby ensuring secure sealing between these components.
