摘要： A filtration device can be configured to form filter cakes and filtrate by filtering solid particulates from a slurry. Some embodiments of the filtration device can utilize a mechanism that is configured to separate the formed filter cake from a disc sector for subsequent processing of the solid particulates of the filter cake and/or the formed filtrate. Embodiments of the filter device and/or mechanisms of the filter device as well as methods of making and using the same can help provide improvements in operational efficiency for processing operations in which solids are to be filtered from a slurry.

摘要： A filter apparatus and method is disclosed for separating solid materials from liquid materials in a slurry fluid. The apparatus includes separable plate members (12, 14) that are pressed against each other to form a filter chamber (10) . The plates have mating surfaces (34, 54) and hollow interior portions that create the chamber. A filter medium (28) is placed between the mating surfaces before the plates are closed. The apparatus includes means for forcing wash fluids, liquids or gasses through the slurry to force the fluids from the slurry and to produce a dry filter cake of the solids. After the filtration has been completed, the plates are separated leaving the filter cake on the filter medium and the filter medium is advanced out of the filter chamber moving a clean filter medium between the open filter plates. Another filter operation them proceeds. The filter medium is cleaned outside of the filter apparatus and can be prepared for reuse. The filter apparatus may include stacked multiple filtration chambers with operating mechanism (100) for accomplishing the simultaneous opening of each chamber.

摘要： In a filtering device used for filtering slurries, or the like, and employing pressed together plate members separated by a filter media, there has been a problem in sealing the mating surfaces of the pressed together plates. In accord with the present invention a groove is provided on each of the plate members at their mating surfaces with the grooves at least partially aligned with each other. A fluid connection is provided to each of the grooves and a fluid at a desired pressure is separately applied to each of the grooves. The fluid pressures in each of the two grooves is different and selected to prevent leakage of slurry or slurry filtrate between the pressed together plates.

摘要： A pressure filter includes two continuous mating surfaces movable relative each other and a filter medium capable of being disposed therebetween. A surface, provided for supporting the filter medium, is bounded by and is substantially coplanar with one of the continuous mating surfaces. The filter further includes a shallow inlet cavity, bounded by the other of the continuous mating surfaces, and an inlet distributor in communication with the inlet cavity. The inlet distributor includes at least one opening and may be of internal or external type. When the mating surfaces are pressed together, a shallow filtration chamber is defined by the inlet cavity and the filter medium. The filter apparatus may include a plurality of shallow filtration chambers, stacked one above the other, and constructed as described above.

摘要： A woven fabric filter medium having particular use in a pressure filter apparatus. The fabric is useful in separating liquids from solids in a slurry fed into the pressure filter apparatus. The fabric is woven in a pattern and of materials that provide desired permeability while being capable of capture of the solids in the slurry and permitting the fluids to flow through. The materials used in the fabric are selected for their ability to resist deterioration from the chemical, heat or abrasive characteristics of the slurry while being capable of being cleaned for reuse in a filter apparatus.

摘要： A pressure-filter is disclosed along with its peripheral equipment that permit the automatic controlled operation of the filter for extracting liquids from a fluid liquid/solid slurry and for the formation of a substantially dry filter cake. The efficiency of the filter apparatus is increased by the use of hot gas as a material for treating the cake within the filter for extracting the liquids as filtrate. The hot gas may be hot air, hot inert gas, steam, or combinations thereof in controlled sequences. The filter is adapted to be able to operate under vacuum or elevated pressure and at elevated temperatures.

摘要： A method and apparatus is disclosed for separating a slurry into liquids and solids in a pressure filter apparatus and for forming a substantially dry and often loosely packet filter solids cake wherein a high temperature and high pressure steam is introduced into an initially formed filter cake in the pressurized filter apparatus to force the steam into the interstices of the formed filter cake and then pressure within the filter apparatus is reduced to permit the steam to flash and to expand within the interstices to absorb any remaining fluids within the formed filter cake and to cause the filter cake to become substantially dry and loosely packed. The filtered solids cake is then discharged from the filter apparatus.
